Abstract: In the operator's station of a vehicle, it has been common practice to mount the steering wheel and the control levers needed to manipulate the vehicle on an adjustable control console. The control console may then be moved fore and aft to accommodate the individual operators that may operate the vehicle to enhance their comfort. Mechanical latching mechanisms have been used that provide only a selected number of positions to which the control console may be placed, and are often rather cumbersome. Hydraulic cylinders have also been incorporated into an adjustable control console design to provide an unlimited number of positions that the control console may assume. These designs, however, are quite complex, involving a plurality of hydraulic cylinders and extensive valving componentry. The present invention overcomes these problems by providing an actuating mechanism that is positioned about one of the pivot shafts that is utilized in the pivotal mounting of the control console to the vehicle frame.

Abstract: In order to soften or stiffen the support offered by an elastic sheet, and in particular a vehicle seat back, the device comprises a flat spring (1) which is at each of its ends connected to the sheet (38), and fixed to a case (2, 3) containing an inclined disc (10, 12). Two discs are fixed to a control rod (24) which is mounted in the frame (36) of the seat and, when this rod is rotated, they cause the cases to be pivoted symmetrically, so that the spring is extended and stiffens the sheet or is shortened and renders the seat more soft.

Abstract: A furniture seat base which employs a series of front and/or back torsioned sinuous spring bands. Predetermined patterns of torsioned bands produce an interaction which generate spring dynamics designed to produce a seat unit which may be sat upon from the front, back, sides, or corners with excellent comfort characteristics. The bands are selectively supported adjacent the rails to obviate objectionable "lean-out.

Abstract: An envelope feeder for mounting on a computer printer, electronic typewriter, word processor or other programmable printer. The envelope feeder uses a centrally located drive separator roller and separating tongue to effect envelope separation.

Abstract: Improvements result from using a feed roller always rotating at a constant surface speed to feed mail items successively with gaps between them from a stack to a franking machine without undue variations in the gap lengths when there are variations in the mail item lengths in respective stacks. A cam rocks a cradle about an input roller axis to bring a feed roller against the stack at a frequency to feed the items forward one by one. Gearing between rollers drives a two speed transmission to a cam via one way clutches. For envelopes shorter than a predetermined limit, the higher speed drive operates. When a rear mail guide member engages envelopes longer than the limit, a lever allows a pawl to disengage a wrap spring clutch disabling the higher speed drive and rendering the lower speed drive effective.

Abstract: A paper feeding apparatus for a printing device, comprising a rotational shaft connected through a one way spring clutch to a forward and reverse rotatable driving motor supported by the printing device, feed rollers mounted on the rotational shaft so as to be in pressure contact with the uppermost surface of pieces of printing paper stacked on a holder table, and a coil spring wound around the rotational shaft and supported at one end thereof by a frame for preventing the rotation in the other direction of the rotational shaft induced by the reverse rotation of the driving motor. The holder table is supported by the frame pivotally through an adjusting means utilizing an eccentric shaft.

Abstract: In the particular embodiments described in the specification, a pressure-actuated brake system for motor vehicles with a brake slip control includes a control means electronically detecting the commencement of a brake slip control operation to provide a signal to increase the brake pressure of at least some of the other wheels which are not yet under brake-slip regulation. The pressure applied to those wheels is increased above the pressure inherently applied by the operator's actuation of the brake pedal at the wheel brake cylinder until such time as brake slip regulation commences at those wheels as well.

Abstract: A continuous scalloped stream of paper sheets is divided into a succession of discrete sections by an accelerating device in cooperation with one or more belt conveyors which receive the sections. The accelerating device has an elongated rubber pad attached to an endless chain conveyor which can move the pad into the path of movement of the stream of sheets toward the belt conveyor or conveyors. The belt conveyor(s) and the chain conveyor are accelerated from the speed of the advancing stream to a higher second speed as soon as the trailing end of the section which is about to be separated from the stream is engaged by the trailing end of the pad on the chain conveyor. The chain conveyor and the belt conveyor(s) are decelerated back to the speed of the stream as soon as the entire freshly formed section is transferred onto the belt conveyor(s) and before the fresh leader of the stream reaches the discharge end of the conveyor for the stream.

Abstract: There is disclosed a piston-cylinder assembly for use as a die spring wherein one end of the cylinder is connected to the source of nitrogen at high pressure to bias the piston outwardly through the opposite open end of the cylinder. The open end of the cylinder is provided with a high pressure seal and the opposite end of the piston is likewise provided with a high pressure seal. An annular chamber of relatively small cross sectional area is provided between the piston and the cylinder. A valve stem on the piston controls a passageway communicating with the annular chamber. Axial pressure is applied to the seal on the cylinder to produce firm sealing engagement with the piston by pressurizing the annular chamber or by arranging a compression spring between the seal and a shoulder on the cylinder.

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.
