Abstract: A machine for feeding cards one by one from a vertical stack including a platform for supporting the trailing edge of the stack and a stripper type support for the leading edge corner portion of the stack in the form of a needle having a downwardly angled tip portion extending inwardly under the corner of the stack so that the leading edge of the bottom card rests against the tip portion of the needle. A suction cup is mounted for vertical movement between an upper position in which the cup is in engagement with the bottom card of the stack adjacent the needle and a downwardly retracted position which is below the tip portion of the needle so that the leading edge of the bottom card flicks past the tip of the needle as the card is drawn downwardly.

Abstract: A robustly constructed box-shaped reinforcing member is securely mounted to a vehicle floor panel with its one end portion located at a side sill above which a door opening is defined. A bracket member is securely mounted to the hinged side door at a portion which is engageable with the end of the reinforcing member when the door assumes its closed position. Thus, when the side door tends to be forced into the passenger compartment by an external force applied thereto, the bracket member movable with the door is brought into engagement with the end of the reinforcing member thereby preventing the side door from continuing its inward movement.

Abstract: A crime prevention apparatus for controlling the operation of an elevator which comprises a night detector for detecting night, a passenger detector for detecting the presence of only one adult passenger in an elevator cage and a start instructing unit for enabling the operation of the cage only when the passenger and the night detectors are operated, thereby allowing the operation of the cage only when one adult passenger rides in the cage during the night and thereby preventing most crimes from occuring in the cage during the night.

Abstract: A pillar garnish cooperates with a center pillar to define therebetween a space which serves as a demister duct for conveying hot, dry air directed from a side demister nozzle to a rear side window.

Abstract: A platform scale in which the force applied to the platform is transmitted to a capacitance transducer whereby the output of the transducer is correlated to the force on the platform. The transducer includes two parallel square plates spaced apart and insulated from each other. Each plate has four slots, one projecting inwardly from each edge of each plate and each slot being generally parallel to the adjacent edge whereby each plate has four identical cantiliver beams. The free ends of each beam of one plate are connected to but insulated from the free ends of the corresponding beams of the other plate. The space between the plates constitutes the dielectric of the transducer and this space is reduced by an amount virtually correlated to the force applied to the platform so that the output of the transducer is very closely correlated to the force applied to the platform on the scale.

Abstract: A time display apparatus for producing an analog-type display using liquid crystal display elements, electrochomic display elements, or the like is described. The display of this apparatus is divided into two parts: a main display portion for indicating the hour and for indicating the number of minutes past the hour in units of 2.5 minutes, and an auxiliary display portion for indicating the number of minutes in units of 1 minute. The main display portion requires 48 display elements, and the auxiliary display portion requires 4 elements, compared to 120 elements required in conventional time displays. Through this reduction in the number of elements, a small-sized, low-priced display apparatus can be achieved.

Abstract: A sheet fed printing press having an impression cylinder with a feed board presenting a sheet with its leading edge in a position for pick up. A rotary sheet feeder is interposed between the feed board and the impression cylinder for picking up the leading edge of the sheet from its stationary position and transferring the leading edge to grippers on the moving impression cylinder. The sheet feeder is directly driven by a high powered electric motor. High resolution pick up heads and associated angle coders produce output signals respectively representative of the phase position of the cylinder and sheet feeder. A programmed phase offset device is provided defining a predetermined relation of desired feeder phase as a function of impression cylinder phase.

Abstract: The pressure regulator includes a valve member which is supported to slide back and forth in a valve housing having a high pressure port, a low pressure port and a bypass port. Pressure fluid from the high pressure port is bypassed through the valve member via an orifice, a passage and a metering opening formed in the valve member, the passage communicating with a compensating chamber located between the valve member and the valve housing. As the bypass flow increases, the increased pressure drop across the orifice reduces the pressure in the chamber to compensate for the progressive resistance imposed upon the valve member by a bias spring and by increasing fluid reaction forces. The compensating chamber enables the regulator to maintain a more substantially constant pressure drop across the high and low pressure ports of the regulator at various bypass flow rates.

Abstract: Linkage is disclosed for adjusting the position of a diesel engine injection pump control rack in dependence on the position of the driver's accelerator pedal and also on a system for automatically maintaining the vehicle speed at a desired value. The injection pump rack is positioned by means of a pneumatic piston-cylinder assembly and connecting linkage. The pressure in the piston-cylinder assembly is adjusted by means of a driver-controlled valve in a supply line from a pressure source, and this valve is adjusted by the driver's accelerator pedal. A normally open valve is also connected in the pressure circuit and a normally closed exhaust valve is provided. When the automatic speed control system is in operation, the driver fully opens the driver-controlled valve (by fully depressing his foot pedal) and the automatic system adjusts the other valves to hold the speed at the desired value.

Abstract: A platform type weighing scale having four platform suspensions mounting a scale platform on a base, a bendable load sensing beam supported by a pair of spaced beam suspensions on the base, first and second transfer means respectively interconnecting first and second pairs of said platform suspensions to each other and to sensing beam at first and second points spaced along the beam to preselected distance from the first and second beam suspensions respectively to apply first and second forces to the sensing beam in a direction transverse thereto that are respectively correlative with the sum of the loads applied to the first and second pairs of platform suspensions, and electrical transducer means for sensing the sum of the moments produced in the sensing beam by the first and second forces.

Abstract: A machine for feeding cards one by one from the bottom of a vertical stack into a receiving nip, the trailing edge portion of the stack being supported on a platform and the leading edge of the stack having a stripper type support in the form of a projection which extends under the corner of the stack, the platform being foreshortened to provide a window adjacent the projection. A suction cup supported on a sucker block faces upwardly into the window. The sucker block is mounted on a block carrier which is reciprocated in forward and retract directions. A cam surface and cam follower are interposed between the sucker block and the carrier and a striker is blockingly arranged in the path of retracting movement of the sucker block so that when the carrier is retracted the sucker block engages the striker causing the sucker block to be cammed upwardly completing an L-shaped path in which the suction cup suckingly engages the underside of the bottom card.

Abstract: A rotary coupling for connecting tubular members is disclosed including a first tubular base member having external threads and a second tubular member with one end telescopically mounted within the first tubular member. Near the lower end of the second tubular member there is provided an exterior circumferential bead and a bearing member shown as a split ring is provided which encircles the lower end of the tubular member and holds it against relative axial movement. An O-ring seal is also fitted over the second tubular member within the bearing member. A retaining nut encircles the second tubular member and threadably engages the external threads of the first tubular member. When the nut is tightened, the bearing member axially grips the bead, with a lip on the bearing member engaging the bead flexing so that the telescoped members can still rotate relative to each other.

Abstract: A sewing machine in which the start and stop of a main shaft is controlled by a cam mechanism through a motion control mechanism at the sewing cycle corresponding to a predetermined number of stitches. The working position of a work holder is controlled by positional data in original instructions stored in a memory. Additional instruction corresponding to the number of stitches to reach the next stop time point controlled by the cam mechanism is prepared for back-tacking, unless the number of stitches corresponding to the original instructions are equal to an integral multiple of the predetermined number of stitches.

A mode switch for selecting on delay, off delay, or dual delay; a sensor polarity switch, and a wired-OR sensor input are provided so that the improved electromagnetic noise immunity of the self-contained design is obtained with a coincident increase rather than decrease in system flexibility.

Abstract: A device for clamping a railroad rail to a concrete tie includes a hollow vertical member which projects down into the tie alongside the rail and has an interior bearing surface which projects downwardly and inwardly toward the centerline of the tie. A generally C-shaped spring is disposed with its upper end abutting an upwardly facing surface on the rail and its center portion projecting down into the hollow member, the lower end of the spring abutting the bearing surface. A wedge acts between another interior bearing surface on the member and the center portion of the spring to flex the latter somewhat and cause the spring to clamp the rail tightly against the tie.

Abstract: Washers are cascaded downwardly from a vibratory feeder into a reservoir which overlies a rotatable disc having a series of angularly spaced pockets. As the disc rotates, each pocket picks up a washer and carries the washer to an assembly station where a screw blank is telescoped into the washer, the screw blanks being delivered to and being carried by heads spaced angularly around a rotatable turret. A feeler senses the approximate quantity of washers in the reservoir and causes the vibratory feeder to be activated automatically when the supply of washers is low and to be de-activated when the supply is large. An arcuate shoe, an agitator, and a sensor also are provided for camming the washers into position to be received by the pockets, for agitating the washers in the supply, for ejecting excess washers from the pockets, for detecting the absence of washers in the pockets and for ejecting any washers which might not receive screw blanks, respectively.

Abstract: A sensor in an air conditioning duct produces a differential pressure signal which varies as a function of the volumetric flow rate of air through the duct. The sensor includes an array of angularly spaced and radially extending arms disposed around and across the duct and each having upstream and downstream sensing tubes formed with ports spaced along their upstream and downstream sides, respectively. Pressure signals are transmitted to the tubes by way of the ports and are averaged by high and low pressure averaging chambers located at the center of the sensor and communicating with the upstream and downstream sensing tubes, respectively. The output signals from the averaging chambers constitute a differential pressure signal which is highly representative of the volumetric flow rate of the air even though the air flows through the duct in an asymmetrical pattern.
