Abstract: A hydraulic motor which varies its displacement in accordance with varying torque loads on its output shaft. The motor is biased to a low displacement, low torque, high speed mode, and changes to a high displacement, high torque, low speed mode when the torque load on its output shaft increases. The motor has eccentrically disposed gerotor gears that rotate and orbit relative to each other to expand and contract fluid chambers on opposite sides of a center line of eccentricity. The gerotor gears can change their orientation relative to each other in response to changes in the torque load on the output shaft, changed, in order to change the displacement of the motor.

Abstract: Weighing apparatus including plural load cells. The load cells have parallel-connected inputs and outputs. The paralleled load cells are connected to a voltage measuring instrument through intrinsic safety barriers. The internal resistances of the load cell are selected such that excitation current limitations imposed by the intrinsic safety barriers are not exceeded and that the load cell output voltage variation accompanying a one grad change in the weight applied to the apparatus is great enough to be measurable by the instrument.

Abstract: A noble gas leak detector is provided using a non-evaporable getter pump to remove active gases but not noble gases during leak detection. The vacuum system is constructed of all-metal valves, metal connection devices and metal passageways to reduce out gassing and minimize the permeation of helium into the system. Valves are appropriately located to seal off unnecessary devices during the actual leak detection. In addition, a process of calibrating a noble gas leak detector is provided using americium 241 alpha as the calibrating source.

Abstract: Deflector device with clamping device for a safety belt in motor vehicles in which the deflector is mounted on slider movable back and forth. The clamping device has a stationary jaw and a space swivelable jaw movable toward the stationary jaw to clamp the belt passing up between the jaws and then over the deflector surface. A spring normally urges the swivelable jaw away from the stationary jaw. An end of slider is disposed adjacent the swivelable jaw such that a belt pull sufficient to overcome the spring force will move the deflector device and attached slide causing the swivelable clamping jaw to swivel and move toward the stationary jaw clamping the belt therebetween.

Abstract: Safety belt system for motor vehicles, with a support point for the belt trap provided above the shoulder of the vehicle passenger to be protected, in the form of an end or deflection fitting which can be fastened at different heights in the vehicle, preferably to the central column thereof, for adaptation to the size of the body of the vehicle passenger. A substantially vertical anchor track is firmly fastened to a central column of the vehicle. The fitting is guided in the track so as to be longitudinally movable. For fixing the fitting at the desired height, a moving slider is likewise supported so that it can be moved lengthwise and locked.

Abstract: A power assisted steering gear has an internal valve member 10 capable of restricted rotation in response to a steering input relative to a valve sleeve 11 rotatable with a pinion 4 driving a rack bar 3. The valve sleeve 11 is rotatable in a cylinder 9 of a valve housing 2 and has an annular recess 25 in an external annular face 12. Recess 25 provides a fluid pressure conduit from an input port 26 and fluid flow is controlled by control ports 13, 14 between the valve members 10 and 11 in response to restricted relative rotation between those members. At axially opposite ends of the annular face 12 the valve sleeve 11 forms alternating pressure chambers 35, 36 communicating with ports in the housing 2 for connection to a power assistance ram. Chambers 35 and 36 communicate through passages 39 and 44 with the control ports 13, 14 to control fluid flow to and from the power assistance ram as directed in response to a steering input.

Abstract: A fluid flow control system includes a priority valve which is controlled by a pressure differential applied across the valve, and which directs priority flow to a steering circuit and excess flow to an auxiliary circuit. The system insures that during steering, a relatively high pressure differential is required to shift the priority valve away from a priority steering position in which all fluid flow is delivered to the steering circuit. It also insures that when the flow to the steering circuit is sufficient to satisfy the steering demand, and the valve is also directing flow to the auxiliary circuit, a lower pressure differential is required to shift the valve in a direction for increasing the flow to the auxiliary circuit.

Abstract: A power assisted steering gear has an internal valve member 10 capable of restricted rotation (in response to a steering input) relative to a valve sleeve 11 integral with a pinion 4 driving a rack bar 3. Control ports 13, 14 between the valve members 10 and 11 are adjusted in response to relative rotation between those members to control fluid flow to power assistance means. The valve members are rotationally biased relative to each other and to a neutral condition of the control ports by a C-shaped spring 21. The valve sleeve 11 and pinion 4 are axially restrained by a bearing 5. The valve member 10 is axially restrained by a compact arrangement of a rod 27 located in a co-axial bore 27a of the valve member 10 and secured by pin 21 for rotation with that valve member and carried by bearings 28 for rotation in the pinion 4. Bearing 28 restrains the rod 27 from axial displacement relative to the pinion.

Abstract: Anchorage for the belt latch of a safety belt arranged in vehicles, especially motor vehicles, with a lock fitting which is connected to the height-adjustable seat. A frame fitting, relative to which the lock fitting can slide in a guide. A locking part for connecting the above-mentioned fittings upon the action of a pulling force cancels the holding force of a connecting element on the belt. The locking part designed as a rocking lever is pivoted on the one side at the height-adjustable seat and on the other side at the lock fitting. The locking part has a detent serration which in normal operation is held by the connecting element (shearing pin) at a distance from a detent element of the frame fitting and is swung, after the holding force is overcome, and is detented by the detent element forming a lock.

Abstract: In electro-erosive machining apparatuses with multidimensional relative motion between a tool-electrode and a workpiece electrode, a simple and adaptable control is provided for these relative operating movements, with a superimposed shaping-limiting control and subordinated cyclic repetitive oblique erosion. In this connection, the tool-feed is limited, within individual oblique-erosion cycles, by achieving a predetermined shaping envelope-surface. The apparatus comprises two separate coordinating-function-transmitters by means of which two operating movements, at an angle to each other, are each determinable according to a resultant relative operating movement between the tool and the workpiece, one being used for shaping-limiting control and the other for oblique erosion. Initiation of the consecutive oblique-erosion cycles is effected by means of a repetition-circuit as a function of a rated-value/actual-value approximation of the shaping-limiting control.

Abstract: Belt strap-clamping device for safety belts in motor vehicles which has a roll-up device with a belt strap which is rolled-up on a belt drum, and which can be rolled out against a spring-force. The belt from the roll-up device is partially wrapped around a deflection member with an arched deflection surface, hinged around an axis, and arranged after the belt drum. The belt strap works in conjunction with a clamping surface which is fixed in the fitting, such that the deflection member is moved when an increased force is applied, and the belt strap is clamped between the clamping surface and the deflection member. At a normal pulling out of the belt the deflection member is held at a distance from the clamping surface by the force of a spring. The deflection surface is formed by a sleeve-like deflection member, which is during normal operation freely rotatable on an eccentrically supported roller, which can be displaced on a predetermined angular path in relation to a clamping surface.

Abstract: In swinging wire guides for generally conical finishing surfaces, the problem exists of a reliable automatic coaxial setting of the guide axes according to the particular angular position of the wire electrode in the workpiece finishing zone.As a solution, the wire guides (DF1, DF2) supported swinging on the support elements (TO1, TO2) are joined together by a coupling device, which has a guide member (FG) joined correspondingly with the support elements. The latter is set by the relative movement of the wire guides (DF1, DF2) to the desired angular position of the wire guides according to the ideal wire guide axis (D--D). Through swinging coupling gears (SK1, SK2) the angle position of the guide member (FG) is transmitted to the wire guides (DF1, DF2).

Abstract: There is disclosed herein a dynamic focusing circuit for the minor deflection circuit, hereinafter referred to as to the vertical deflection circuit, for a cathode ray tube to compensate for defocusing characteristics thereof. Such a cathode ray tube employes a major deflection circuit, hereinafter referred to as the horizontal deflection circuit, for deflecting the beam along a horizontal axis at a relatively high raster scan frequency, such as on the order of 28 KHz. Additionally, such a cathode ray tube has associated therewith a minor deflection circuit for deflecting the beam along the vertical axis at a second substantially lower scan frequency and which may be on the order of 50 Hz. A focusing circuit normally receives a steady state DC focusing signal for focusing the beam as it is scanned along the respective horizontal and vertical axes.

Abstract: A scale includes a movable platform which is supported by a plurality of improved force transmitting assemblies. Upon sideways movement of the platform, the force transmitting assemblies and platform interact to align the force transmitting assemblies and to center the platform. Each force transmitting assembly includes a slider which is movable along a base surface. A rocker pin transmits force between the slider and a load cell beam which is connected with the platform. When the platform is moved sideways relative to the base, the rocker pin is tilted to a maximum offset position in which horizontally offset vertical force components are applied to the rocker pin. In accordance with the present invention, stop surfaces on the slider and load cell beam are disposed in abutting engagement when the rocker pin is in a maximum offset position.

Abstract: An improved method of applying color to hair includes gripping the hair between a pair of panels having nonlinear edges. While the hair is gripped between the panels, a hair coloring agent is applied to the portion of the hair extending outwardly from the nonlinear edges on the panels. Heat is applied to the hair to expedite the coloring of the hair. The panels are then moved outwardly along the hair and the hair is cut along the nonlinear edges of the panels.

Abstract: An apparatus for supplying fluid under pressure, such as compressed air, to movable using devices, includes a feed line having tap points spaced along it, with a tap valve at each tap point. A connection unit for connecting the feed line to the user is movable along the feed line and can receive fluid at any tap point. As the connection unit slides into place at the tap point, the tap valve automatically opens to supply fluid. Each valve has a rotary or slide-type valve member movable between open and closed positions, which is always exposed to equal fluid pressure all about it so as to require only a small force to actuate the valve. The valve member is tubular and open-ended and extends parallel to the feed line. Both mechanical and magnetic means for actuating the valve member are disclosed.

Abstract: Mechanism for blocking a belt shaft of a roll-up device for a safety belt in a vehicle characterized by the features that the control pawl is pivoted in the stationary roll-up housing of the mechanism in the tangential direction range to the pitch circle of the teeth, can be swung with the detent tip of the control pawl by positioning means of the danger sensor into the range of the teeth of the control disc, can be swung further upon rotation of the control disc toward the tooth base by a pulling force on the safety belt against the detent tip with the latter, taking along the blocking pawl into the area of the ratchet wheel teeth and can be moved, at least in the range of its tip, against an elastic force by a pulling force on the safety belt transmitted via the cam of the control disc where if a tooth of the control disc is struck by the tip of the control pawl, a distance between the next tooth of the ratchet wheel is provided by mechanical design to ensure engagement of the blocking pawl with the teeth o

Abstract: Bottom opening pockets in a newspaper stuffing machine sequentially move newspapers to a transfer station at a first speed with closed edge portions of the newspapers downward and major sides of the newspapers on which headlines are printed facing in the direction of movement of the pockets. The pockets are sequentially opened and the closed or folded edge portion of each of the newspapers in turn moves into engagement with a receiving conveyor. The receiving conveyor accelerates the closed edge portion of a newspaper while the open or cut edge portion of the newspaper remains in a pocket and travels at a slower speed. This results in deflecting or bending of the newspaper. As the closed or folded edge portion of the newspaper is accelerated, the paper is moved into an underlapped relationship with an immediately preceding newspaper. The underlapped newspapers are moved into an overlapped relationship by an inverter.
