Abstract: A sheet transfer apparatus is for a sheet counting apparatus in which paper sheets stored in a hopper in a stacked state are fed by a payout roll from the hopper to a stacker at the downstream side of the payout roll. A guide assembly is disposed opposite to the periphery of the payout roll and is adapted to separately guide the paper sheets from the hopper toward the stacker in cooperation with the payout roll. According to the invention, the guide assembly, which has a frame member carrying a separating roll, a pinch roll and a guide plate, is pivotally mounted so as to be movable between a closed position in which it is close to the periphery of the feed-out roll and an opened position in which it is farther away from such roll. The position of the frame member is controlled by a pivotable opening/closing device engageable with the frame member for selectively holding the frame member in the closed position or the opened position.

Abstract: An oscillation damping device having a differentiated action in the two directions of sliding of a rigid stem with respect to a rigid case, comprising a plurality of rigid rolling elements, interposed between a rolling race of viscoelastic material and one or more skidding metallic races, shaped in such a way that upon moving the stem in one direction, the rolling elements are encased within said metallic races, spaced out from the viscoelastic race and exert a limited braking effect, while upon moving the stem in the opposite direction, the rolling elements are advanced into interference with the viscoelastic race and thereby exert a strong braking effect.

Abstract: An elastically damping device for the suspension of an engine of a vehicle, by which the engine vibrations are prevented from being transmitted to the body of the vehicle, is disclosed. The damping device is provided with a first fluid chamber and a second fluid chamber, each of which is defined by an elastically deformable wall. The fluid chambers are separated from each other by means of a partition plate, of which at least one portion is formed into a movable plate being movable in such a direction as to lower the increased inner pressure of the fluid chambers, and which has a restricted passageway for communicating the fluid chambers. The damping device of the present invention further comprises two stopper portions for stopping the movement of the movable plate and an electromagnetic coil for operating one or two stopper portions so as to control the movable distance of the movable plate in accordance with the driving condition of the vehicle.

Abstract: A speed governing mechanism is provided utilizing plano-centric gearing and centrifugal braking. An outer cylindrical member serves as a cable drum and is rotated by playing out of the cable. A central shaft is fixedly mounted for supporting the assembly. Plano-centric gearing within the outer cylindrical member turns an inner rotary member on the fixed shaft at an increased speed, while a centrifugal brake assembly is fixed on the inner member and has brake shoes that fly outwardly under centrifugal force to bear against an inner cylindrical reaction surface on the outer cylinder, and thereby to limit the speed of rotation of the outer cylinder. Guides are provided coacting with the brake shoes to cause them to move rearwardly relative to the direction of rotation, and thereby to provide a wedging action with the reaction surface.

Abstract: A high speed feeder for cartons being fed into a cartoner includes both mechanical and fluid flow environments for precisely delivering cartons. A preferably inclined conveyor receives cartons stacked on their edges and in a generally vertical orientation. A rotating metering wheel at the downstream end of the conveyor engages the top edges of the cartons and separates them one at a time from the incoming stack. A blower is provided to direct air onto the cartons adjacent the metering wheel to (a) blow the cartons against the metering wheel, (b) blow air between the first and second cartons of the stack as the metering wheel separates the first from the second, and (c) blow the cartons down to a horizontal attitude. Horizontal feed chains having feed lugs receive the horizontal cartons and advance them one at a time into the cartoner. Vacuum nozzles are provided to aid in controlling carton placement on the feed chains and lugs throughout a broad range of feed speeds. Methods are included.

Abstract: An automatic sheet feeding mechanism adapted to separate a single sheet from a stack of sheets and transfer the single sheet via airjets to the exposure platen of an exposing apparatus. After airjet positioning and exposure, the single sheet is lifted from the platen and delivered to an exit port also via airjets.

Abstract: This suction foot or "sheet sucker" has a cylinder and a hollow piston fitted in the cylinder. The piston has a piston rod whose tip protrudes downwardly from the cylinder to apply suction to the top sheet of stock in a small press. The cylinder is supported from and moved by a hollow support rod that is connected with the suction system of the press. The piston and rod are spring-loaded upward relative to the cylinder. The hole in the support rod communicates with a point in the cylinder cavity below the piston. Applied suction consequently draws the cylinder and rod downward, against the spring action, in effect telescoping the suction foot tip outwardly toward the stock. When a sheet of stock closes the bottom end of the hollow piston and rod, pressure on the cylinder is equalized and the suction foot tip retracts, raising the stock for travel into the press. The necessary air communication is effected by several fine air passageways in the cylinder side wall and top wall.

Abstract: The invention relates to a brake jaw arrangement for a disc brake. The brake jaw essentially consists of two brake levers which carry on one end thereof a brake lining holder and on their other end are connected to cooperate with an operating mechanism. The operating mechanism causes the ends of the brake levers equipped with the brake lining holders to be moved toward each other or away from each other.

Abstract: A dynamic linear vibration damper consisting of a support member and an inertia member assembled by an elastomer for vibration damping purposes. An extension defined on the support member is received within an opening in the inertia member, and an elastomer interposed between the extension and the opening surfaces is installed under tension whereby the resiliency of the elastomer places the elastomer under compression as confined by the opening to frictionally maintain the assembly of the components.

Abstract: A sliding caliper disc brake includes a caliper slidably mounted on a fixed torque-taking member to urge one friction pad onto one side of a rotatable disc and having a fluid actuated piston which urges the other friction pad onto the other side of the rotatable disc. The caliper is connected to the torque member by a pin so as to permit sliding of the caliper in an axial direction of the rotatable disc and also pivoting of the caliper with respect to the torque member. The pivoting of the caliper in the inward direction is restrained by an extension which is formed on the caliper and is in contact with the torque member while the pivoting of the caliper in the outward direction is restrained by a link plate which is oscillatingly disposed on one friction pad and is in contact with the caliper.

Abstract: In a fluid-pressure operated braking system for vehicles operating fluid from a supply for actuating a wheel brake is supplied to the brake through a skid control unit interposed in the line between the supply and the brake, and a skid responsive device responsive to a skid signal is incorporated for operating a valve assembly to relieve the pressure of the fluid supplied to the brake at a skid point. The unit incorporates a memory chamber for controlling the rate of brake re-application following correction of a skid, and the memory chamber is charged with air only when the skid signal is received. When separate control units are provided for the brakes of wheels at opposite ends of an axle, the memory chambers are interconnected by a pneumatic connection incorporating a restrictor.

Abstract: An envelope hopper (20) is capable of selectively handling stacks of short envelopes (SE), stacks of long envelopes (LE), or stacks of envelopes of intermediate dimensions. The envelope stack rests on a table frame (26) in such a manner that at least a portion of a bottom-most envelope overhangs a breaker plate edge (32). At appropriate points in an machine cycle suction cups (64) rise from below a breaker plate (30) to attract the underside of the overhanging envelope and then fall to deflect the attracted envelope. Rotating arcuate surfaces (202) of segmented rollers (66) thereafter make contact with the underside of the deflected envelope. Cooperating rollers (72) are pivoted into a position to contact the upperside of the deflected envelope, to engage the deflected envelope between the rollers (72) and the driven segmented roller (66), and to apply a pressure which facilitates displacement of the envelope from the stack by the application of rotational motion from the segmented roller (66).

Abstract: Disclosed is an antilock braking device including a first braking hydraulic adjusting member actuated so as to restrain braking oil pressure of wheel cylinders individually corresponding to left and right front wheels in response to antilock braking oil pressure for front wheels; a second braking hydraulic adjusting member actuated so as to restrain braking oil pressure of wheel cylinders individually corresponding to left and right rear wheels in response to antilock braking oil pressure for rear wheels; an antilock control system having a reservoir and a pump for pressurizing control oil from said reservoir to generate said antilock control oil pressure; and a tandem type master cylinder having a pair of output ports independent of each other connected to said both braking hydraulic adjusting members to generate braking oil pressure of each of said wheel cylinders, characterized in that a proportional reducing valve is interposed between both braking hydraulic adjusting members in order to supply braking oi

Abstract: A pneumatic sheet feeder for removing individual sheets from a stack comprises a table having a surface for supporting a stack of sheets. A pair of parallel guide rails are provided on the table and with facing surfaces so that the stack is confined between the guide rails for movement in a feed direction across the table. Blast nozzles are provided in the guide rails for blowing air against the stack to form an air cushion between lower sheets of the stack. A suction cylinder is rotatably mounted to the table and includes a suction chamber therein for receiving a vacuum. Radial openings in the suction chamber cause a suction induced adhesion of a leading edge of a lowermost feed in the stack so that with rotation of the cylinder, the lowermost feed is fed in the feed direction away from the rest of the stack. A single blower is provided with a pair of two-way solenoid valves and a switching circuit is provided for alternately activating the valves.
