Abstract: A coin sorter is provided comprising a rotatable disc with a resilient surface and a stationary disc having its first surface positioned proximate to the resilient surface of the rotatable disc. Coins placed between the two disc surfaces are pressed into the resilient surface by pressure from the stationary disc surface. Accordingly, coins rotate with the rotatable disc. Selected areas of the stationary disc are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force. The selected areas of the stationary disc which are recessed, guide the coins along a path which results in each demonination of coin escaping from between the two discs at different positions along the periphery of the stationary disc. Recesses and ridges are provided on the underside of the stationary disc which recirculate improperly aligned coins.

Abstract: An engine stopping device for rendering an internal combustion engine of a spark ignition type by grounding an ignition circuit includes a contact section for achieving grounding which is exposed to air flow passing through an engine cooling air passage, to clean off dry grass or other foreign materials from the contact section.

Abstract: A gripping mechanism is mounted on a carriage and is adapted to be shifted back and forth along an inverted L-shaped path to pick up and transfer parts. Inverted L-shaped cam tracks are formed in a main support member and receive and guide rollers which support the carriage. The cam tracks and the rollers are arranged to allow the rollers to roll freely without skidding while preventing radial play between the rollers and the tracks. A flexible drive linkage is connected between the carriage and its actuator and is capable of yielding in both directions in order to prevent damage to the actuator if the carriage becomes jammed when the carriage is being either advanced or retracted. Before being picked up by the gripping mechanism, the parts are held in a track by an escapement having spring-biased fingers adapted to move between open and closed positions.

Abstract: The turning cylinder and storage cylinder in a perfecting printing press is provided with changeover mechanisms having spring-loaded electromagnetically releasable latches and sensors for detecting latched adjustments. Moreover, a contactless sensor is provided for detecting clamping of the calendering suckers in the storage cylinder even when the cylinder is rotating. Contactless proximity switches determine the correct phase adjustments between the storage cylinder and the turning cylinder for both perfecting and first form printing. An access door and interlock guarantees that the cylinders are turned to a normal position and braked before the access door is opened, and the access door cannot be closed for subsequent printing until changeover has been completed. An indicator array indicates the sequence of adjustments to follow and abnormal conditions.

Abstract: A method of inhibiting the absorption of nutritional elements, principally food, from the gastrointesinal tract is disclosed which comprises ingesting perfluorodecalin in an amount sufficient to form a nutritional element-impermeable film thereof on at least a substantial part of the inner wall of the upper intestine and maintaining the film for a time long enough to inhibit the absorption from the gastrointestinal tract of a significant proportion of the ingested nutritional elements. An emulsion dosage form is preferred for carrying out this method, which emulsion contains perfluorodecalin, water, and a non-toxic emulsifier, preferably Pluronic F-68, and optionally flavoring and/or coloring agents.

Abstract: A windscreen mounting arrangement for a motor vehicle comprises an integral extrusion defining to channels facing in opposite directions. One channel grips a flange surrounding the windscreen opening, and the windscreen glass is fitted into the other channel. After that, a stiffening member is placed in a groove in the extrusion to hold the glass in position. A metal reinforcing carrier embedded in the extrusion has a channel-shaped portion embracing one channel and an integral sideways extension which is embedded within the material defining the base of the other channel. This sideways extension facilitates initial fitting of the windscreen mounting arrangement onto the flange and stabilizes the mounting arrangement when it is bent to follow curves in windscreen openings.

Abstract: A reversible d.c. torque motor advances and retracts a cone mechanism for radially expanding and contracting the stones of a tool for honing a bore in a workpiece. The motor is adapted to advance the cone mechanism at three different speeds so as to effect expansion of the tool first at a rapid traverse rate, then at a slower coarse feed rate and then at a still slower fine feed rate. Pulses representative of changes in position of the cone mechanism are routed to and are counted by a reversible counter which causes the cone mechanism to retract to different starting positions as the stones of the tool wear and reduce the effective diameter of the tool.

Abstract: A photographic camera converting a captured optical image to a series of electronic signals is disclosed comprising a recording mechanism to record these signals including a recording head which executes transverse scanning movements with reference to a magnetic record medium so that at least one scanning movement corresponds to each image. The magnetic record medium is contained within a cassette that is removable from the camera body.

Abstract: A rivet having a cylindrical head portion, a cylindrical shoulder portion of reduced diameter and a tenon portion of further reduced diameter is projected through first and second parts which are to be fastened together. The head portion abuts one side of the first part, the shoulder portion extends a substantial distance through an opening in the first part and the tenon portion projects through and beyond a hole in the second part. An axial bore opens through the head portion and extends into the shoulder portion but stops short of the tenon portion, the bore terminating in an end wall. A first tool is projected into the bore and bears against the end wall to place substantially all of the shoulder portion in tension and to hold the rivet while a second tool engages the tenon portion to deform the latter and form an enlargement engaging the second part, the tenon portion thereby being in compression.

Abstract: Described is a belt buckle to which may be attached a tool in the form of a flat plate. The buckle body is formed by a fitting case and a base plate mounted to the rear surface of the fitting case. A leaf spring is mounted in the buckle body for pressingly holding the tool in the housed state. The plate spring has a pair of short strips for acting on the central part of the tool and a long strip for acting on the inner end of the tool. The upper and lower sides of the foremost portions of the fitting case are bent back to provide an engaging portion for preventing inadvertent withdrawal of the tool from the buckle body. When withdrawing the tool housed in the buckle body, it is only necessary to apply finger pressure on the end of the tool exposed through the central end notch of the fitting case.

Abstract: A wheel-mounted tire pressure sensor employs a Bourdon tube which deforms in relation to tire pressure to drive a pivotal arm. Opposite ends of the arm support magnets which can close reed switches arrayed around the path of travel of the magnets. The reed switches are connected to passive resonators in such a way that for each of a number of regions of travel of the arm, a unique combination of resonators is activated. The resonators are connected to a wheel-mounted antenna which faces a stationary antenna. Frequency signal matching the frequencies of the resonator are sequentially broadcast by the stationary antenna to the resonators, which are excited to oscillate if activated by the corresponding switch or switches. The excited resonator broadcast their frequencies back to the stationary antenna and to a display unit which decodes the combination of resonator frequencies to display the corresponding tire pressure.

Abstract: A miniature cassette is disclosed comprising a casing having two rotatable spools for storing magnetic tape, guide rollers mounted in the casing for guiding the tape in different paths between the spools, and apertures in the end walls of the casing allowing the tape to exit from and enter into the casing along different paths between the spools wherein one of the paths is substantially perpendicular to the end walls of the casing.

Abstract: The invention relates to intruder detection systems of the microwave radiation type in which a number of microwave transmitter/receiver units are placed around an area under surveillance. If a moving intruder is present, the microwave radiation emitted by one or more of the units will undergo a slight change when reflected back to the same unit. Mixing the received radiation within the transmitted radiation will therefore produce a low frequency output which can be detected by a Doppler amplifier. The Doppler amplifier will also produce an output if microwave radiation inadvertently received by that unit from another unit has a frequency which is such that the mixing produces a signal within the Doppler amplifier bandwidth. In order to prevent the latter signal causing a false alarm, any Doppler amplifier output is used to shift the frequency of a modulator controlling the pulse repetition frequency of the transmitted radiation.

Abstract: A fluid transfer system including a cap member having a first fluid transfer member therein and being removably mountable on a second fluid transfer member. Cooperating lugs and slots formed by the cap member and second member lock the two members together when the cap is placed on the second member and rotated relative thereto. A resilient annular gasket is disposed between the second member and cap member and surrounds the liquid passageway therethrough to prevent leakage. The second member and cap members form an annular space on one side of the outer peripheral portion of the gasket, and an annular bead presses against the other side of the outer peripheral portion of the gasket so that the bead bends that portion of the gasket into the annular space to effect a liquid-tight seal on both sides of the gasket.

Abstract: An ink metering arrangement for a printing press including a fountain roller having a plurality of slides arranged edge-to-edge in respective column positions, each slide being adjustable so that its tip forms a gap with the roller thereby determining the rate of ink flow in the corresponding column position. Each slide has a reversible motor for driving the slide over a limited range of movement with respect to a slide reference position. A potentiometer is connected to the motor for producing an electrical output signal corresponding to the degree of slide displacement, the potentiometer having a stop to establish a reference output condition. A slip clutch is interposed in at least one of the motor connections so that when the motor is energized in a first direction the potentiometer and slide are both driven to their reference positions accompanied by relative slipping movement of the clutch notwithstanding the fact that the tip of the slide may have been shortened by wear against the roller.

Abstract: In accordance with the invention, a plate-clamping mechanism is provided for clamping and locking flexible printing plates on a printing cylinder wherein a clamping jaw fitted into a cylinder cavity has a leading edge for clamping one end of printing plate which is (1) non-parallel to the cylinder's axis of rotation and (2) coincident with the periphery of the cylinder when the clamping jaw is in its opened or closed position. In addition, the clamping jaw's axis of rotation is parallel to the jaw's leading edge. Such a clamping jaw eliminates any void between the printing plate and the cylinder surface which might otherwise exist after the plate is tensioned and clamped: such a void is common in printing cylinders with clamping jaws having leading edges non-parallel to the cylinder's axis of rotation.

Abstract: An automatic calibration arrangement for a tape recorder is disclosed. The arrangement includes a microprocessor which responds to pre-stored calibration signals to write predetermined tones onto each track of the tape using the record circuits and record heads of the tape recorder, and then monitors the corresponding signals as replayed by the replay heads and replay circuits of the tape recorder so as to automatically adjust parameters of the record and replay circuits accordingly. The record and replay circuits are arranged to be settable by means of digital numbers produced by the microprocessor. Parameters which may be adjusted include record bias, record drive current (to produce 1% third harmonic distortion), and the mid band and band edge filter circuits, and phase adjustment of the replay circuits. Recorders not having replay circuits (but having replay heads) can still have their bias level and record current calibrated and can record replay calibration frequencies for external calibration purposes.
