Abstract: A radio-controlled rolling toy has a hollow shell containing a radio-controlled vehicle which may be caused to move sidewardly relative a shaft mounted coaxially with the outer surface of the shell. The vehicle may also be caused to perform a rotation relative the shell, the combination of said two movements enabling the shell to follow any type of tortous path on the ground.

Abstract: The casing serving as a safeguard against burglary for tape recording cassette containers is made of a plastic material and includes in the narrow wall opposite of the insertion opening a perforation of the wall close to an edge and extending at its center substantially at the level of the angularly adjacent inner surface of the casing into the casing. Two locking bodies arranged adjacent of each other and integrally connected by a base disk and having a hook-like broadened and thereafter wedge-like sharpened end section are inserted into the perforation. The hinged lid of the tape recorder cassette container is kept somewhat depressed by the hook-like broadened end section which end section simultaneously engages over the adjacent side wall of the contained wherewith the container of the cassette and the casing are interlocked. In order to unlock the connection the interconnection between the locking bodies and the base disk resting against the outside of the casing is ruptured by means of a special tool.

Abstract: This invention provides improved structure and detection methods for electromagnetic field ferromagnetic security detection stations of the type conventionally used at airports and the like. Improved sensitivity to ferromagnetic masses, such as knives or firearms carried by a person in the vicinity of the feet, ankles or lower legs is achieved by interosing a riser platform to assure that the person is introduced into the detection electromagnetic field above the floor or ground plane a predetermined distance that increases sensitivity of the detection of ferromagnetic msses carried by the person in the lower leg portion of the body. Even greter improvement in detectability is afforded by the requirement that the person stand in place at a position in the detection field affording more sensitive detection. The invention is simply used to retrofit field stations by introduction of a riser platform.

Abstract: For better efficiency in removing scale and deposits in pipes, a high gauss permanent magnet unit, requiring no servicing or external power, mounts on the exterior surface of the pipes for establishing a flux path encompassing a greater portion of the flow path than heretofore feasible. Even more effectiveness results from mounting units in diametrically opposed pairs. The units have a pair of alnico magnetic plates straddling an arc on the pipe surface to focus the magnetic flux into a preferred pattern into the fluid flow path. By blending two permanent magnetic circuit paths from different permanent magnetic materials offering different advantages, a multi-pole, multi-axial magnetic flux generator uniquely distributes and concentrates the magnetic forces for maximum de-scaling effect. Standard units fit different diameter pipes, provide very high fluid treatment flux concentrations over a wide range of pipe cross section area and have long life in the presence of magnetic interference or electrical shock.

Abstract: The invention concerns the joining of webs in adjacent cassettes, particularly as a supply for a ticket issuing machine. A web supply system comprises a plurality of cassettes (12) each containing a fan folded web (13) of material, each cassette having a common web exit and web entrance, the cassettes being arranged side by side and the leading end of a first of the webs being arranged to pass through the exit of that cassette to an operating/issuing machine and the trailing end (19) of the web of each cassette (except the last) extending through the entrance of that cassette and being joined to the leading end (19a) of the web from the next adjacent cassette, the web extending in a loop between adjacent cassettes so that the web from all the cassettes can be supplied as a continuous web to the processing/issuing machine.

Abstract: This invention provides improved body length adjustment value structure for a vacuum powered lifting system of the type that embodies a variable length lifting body responsive to the differential of pressure inside that body with atmospheric pressure to resolve critical manual control problems. Thus control is provided by proportional movement of a control member over a substantially linear range producing a smooth progressive movement of the lifting mechanism. This permits non-critical lowering and release of a work load object by unskilled operators. Thus, an air injection valve with an air release port, is positioned within the lifting body having an elongated slot operable over a control range proportionately change the body length by release of a progressively increasing flow of air into the body to increase air pressure and body length over the critical range of lowering and releasing the work load object in response to a corresponding substantially linear movement of the control member.

Abstract: A satellite controlled TV audience response system provides means for current processing of answers to audience polls so that answers may be presented in TV pictures alongside the questions substantially instantaneously. This system has the capacity to process both local audience responses such as those in the vicinity of a particular TV station, and audiences over a large geographic area, so that responses can be analyzed to take into account regional differences in response or differences in the listeners to different TV station audiences. The system is fully capable of interaction with local cable networks. Responses can be analyzed at local ground stations for billing purposes, etc., and can be analyzed at the satellite station for retransmission of various audience responses to the polled audience. This invention makes feasible a fully automated instantaneous nationwide TV polling and response feedback system.

Electric pulses having a selected shape and carrier frequency are digitally synthesized in response to a count comparator.

Abstract: A sealing arrangement, particularly for a rail vehicle slack adjuster, between a generally tubular housing (7) and a rod (1), which is axially and rotatably movable relative thereto, has a cup (10) engaging the rod with a sealing ring (11) so as to be movable with the rod. This cup extends along the rod over the free end of the housing so as to form a type of labyrinth sealing. The cup is preferably provided with a protective and guiding internal ring (12) cooperating with the housing.

Abstract: Shingles are formed of a top sheet and a bottom sheet of plastic confining solar energy conversion means therebetween. The sheets are sealed together about a perimeter to form flanges for fastening in overlapped order to a roof. The contour of the shingles is domed to provide for better solar energy conversion efficiencies. Insulation and support members disposed along an underside of the dome sructure provide support to the assembly and insulate the roof. Decorative structure and shingles of this nature permit a roof surface which does not belie its nature as a solar heating system. The plastic sheets may either form flow passageways for a solar heatable fluid or may encompass photovoltaic cells to form unitary shingle-solar conversion structure.

Abstract: A pair of slit type horizontal fin rolls (18) and a pair of vertical side rolls (19) having such a shape as having the conventional vertical side roll (19) formed by contracting its center portion are utilized, and due to the construction in which one set of each horizontal fin roll (18) and vertical side roll (19) adjustable horizontally, the depressing force is not applied to the material, and since the edge is restrained and shifted widthwise only with the horizontal force of the vertical side rolls (19) rotating freely, threading can be conducted very smoothly irrespective of the sectional shape of the material after break down, and even if the material size is changed, the threading can be conducted very smoothly without adjusting the roll position as strictly as in the past.

Abstract: Apparatus for centrifugally extracting meat from crab bodies is disclosed. The apparatus comprises a housing (10) for supporting a rotating drive means (32). A crab body holding means (26) is supported along a spin axis so as to restrain crab body sections in a selected orientation against a support structure (116). The selected orientation is such that when the holding means (26) spins around the spin axis, centrifugal forces on the crab bodies extracts the crab meats through openings in the shell structure. As the meat is propelled from the holding means (26) it is collected by the receiving compartment (30). The support structure (116) contacts and supports the crab body during the spinning of the crab body at specific locations of the crab shell structure to provide the minimum amount of obstruction to the meat being extracted while at the same time minimizing breaking and collapse of the shell structure. Further included is a braking means (34) for stopping the spinning of crab body holding means (26).

Abstract: This invention relates to a catheter (1) and accompanying system for diagnosis of the cardio-vascular system of a patient. The catheter (1) flexible tube body (2), having at least one channel (3) therethrough leading from the extracorporal proximal end to the distal area having a fluid discharge opening (6) is introduced into preformed vessels (31) of the body to extend into the heart for measuring physical parameters representative of the cardiac condition of the patient. A temperature sensor (8) is disposed on the catheter toward the proximal end with respect to the opening (6) at the distal end to allow for diagnostic and interventional measures to be taken in the left heart. Between the opening (6) and the sensor (8) may be disposed a dilatation balloon (7) inflatable from the outside. Also, it is advantageous to provide a second temperature sensor (17) in the area of the distal openings (6) as well as a further opening (21) in the area of the first temperature sensor.

Abstract: The conventional keyboard is replaced by a virtual keyboard pattern on the computer screen by this invention. Selection of keystrokes is made by a mouse, or the like, positioning a cursor at a desired key for keyswitch selection. This manner of selection of pre-formed patterns available from the computer, such as alphanumeric characters and computer commands is particularly advantageous in a computer aided drafting and design system. Thus, notations and lettering need not be formulated by analog movement of the mouse, but can be selected digitally from the computer store by keyswitching. The resulting equipment therefor eliminates the conventional keyboard but not its operational advantages thereby permitting full computer operation with a mouse or the equivalent.

Abstract: Conveying apparatus for use in an environment having significant variations in temperature, and having a molded plastic screw conveyor on a metal drive shaft is disclosed. The molded plastic screw conveyor includes a non-circular axial aperture which receives a cooperating drive shaft with a coefficient of expansion different than the plastic screw conveyor. The cross-sectional shapes of the drive shaft and the axial aperture extending through the plastic screw conveyor are such that rotation of the drive shaft results in rotation of the plastic screw conveyor. However, axial motion between the plastic screw conveyor and the drive shaft can occur to accommodate variations in length due to changes in temperature. A journal plug or end means is also included which may receive rotational forces from a motor or other source. The journal plug is joined to the drive shaft such that rotation of the journal plug results in rotation of the drive shaft and consequently in rotation of the plastic screw conveyor.

Abstract: Physiological activity of a patient is detected and analyzed by means of a single sensor situated in the vascular system of the patient. Pulmonary activity is derived from analysis of changes in cardiac activity, such as sensed from blood flow, pressure or volume changes, measured in a preferred embodiment as impedance change within the right heart. Pulmonary activity is separated from cardiac activity implicit in such changes by filtering lower and higher frequency components. The separated signals are processed to derive control signals for stimulating the heartbeat in a pacemaker system, preferably by a single sensor-stimulator electrode implanted within the right heart. Thus, a single functional parameter, namely intra-cardiac impedance, varying both with the intrathoracic pressure fluctuations following respiration and with cardiac contraction is representative of the pulmonary activity and of the cardiac activity.

Abstract: A data processing keyboard system is provided wherein data and command signals from the keyboard are entered by two or more successive keystrokes. This makes available from the comprehensive capability of present day computers large numbers of keyboard accessible commands. Also surprisingly then this invention can replace a normal QWERTY typewriter keyboard with most of its functions by a set of only seven or twelve keys. Thereby alphabetic characters, decimal digits and a store of computer command entries may be processed with each entry requiring two or more strokes of the computer keyboard keys. Functional commands such as spacing, return or shift can be intermixed with the choice of data characters. Means for shifting from a single-stroke-per-entry computation mode to a two-stroke-per-entry alpha mode of computer operation may be provided. Keyboard selected modes change the key assignments.

Abstract: Automatically operable protection is afforded to eliminate pollution to the atmosphere caused by failure of fabric filter bags in a filter network. This is achieved by increases after bag failure in aerodynamic flow volume of fluid in the flow path to the individual filter bags past a closure valve structure. Critical and rapid response is achieved by an aerodynamic substantially flat plate member pivotably mounted off center to initiate movement toward a closure position. A counterweight on the smaller area side moving toward closure assures closure of the flow path. The valve may be latched close, and may telemeter closure to a central location visible to an operator. For reverse jet type systems the valve is mounted in a fluid output flow path from the filter bags in a location where the reverse jet flow does not pass through the valve. Consistent operation of a plurality of networked valves is assured by locating them in flow path positions having little turbulence.

Abstract: Alphameric electronic computers are made with fewer keys in keyboard assemblies for selection of a large range of input characters and instructions. To achieve this the computer and keyboard operates in two modes with one providing for example decimal digit processing from single keystroke entries and the other providing for example alphabetic character processing from two successive keystroke entries. The keys, strokes and instructions are cooperatively integrated by means of a visual display integrally located on the computer with coded indicia representing the entries and identifying the key or keys to be stroked and in the case of successive keystrokes representing the sequence of stroking. Accordingly reference to external manuals for computer operating or data entry instructions is rarely necessary.
