Title: Heavy loads handling system - carriage mounted hydraulic jack supports load and is moved stepwise by hydraulic cylinder operating against notched guide rails
Inventor: CERNY ROSTISLAV DIPL ING
IPC: B65G7/02
Filed: 1974-10-08
Abstract: A roller mounted carriage supports a load on a hydraulic lifting jack. The carriage is located between guide rails that consist of notched plates. Horizontal motion is produced by a double acting hydraulic cylinder operates by a manually actuated control valve supplied from a power pack. The cylinder piston rod is equipped with a thrust bar that locates in the notched sections of the guide rails. In operation the control valve is set to supply flow to the left hand side of the cylinder and the thrust bar rides over the guide rail projections via a taper. When fully extended the control valve position is inverted and the thrust bar reacts against the rail notches. The load is moved axially the stroke distance of the cylinder. Repeated operation of the control valve results in step-by-step horizontal movement of the load.

Title: Filling a porous sheath with electrode active paste - by temporarily blocking the pores, injecting paste under pressure, then unblocking the pores
Inventor: LAHME NORBERT ING GRAD
IPC: H01M4/16
Filed: 1974-12-20
Abstract: In a lead acid accumulator using porous sheaths permeable to electrolyte surrounding the leads and packed with partly active material comprising PbO, H2SO4 and sufficient water to reduce the viscosity, the sheaths are filled with paste by injecting under pressure after the sheaths have been partially or completely conditioned with a material which fills and partly or completely covers the pores, and the permeability to electrolyte is reestablished (in)directly. The conditioning material is pref. a film former such as 4% CMC, PVA etc. which blocks the pores during filling and is subsequently removed with a solvent.

Title: Valve controlling exhaust gas injection into inlet manifold - operated by accelerator pedal through elastic connecting rod
Inventor: BAUER ALFRED
IPC: F02M26/52
Filed: 1974-02-15
Abstract: Reducing the temperature of combustion in an I.C. engine reduces the production of the harmful gas nitrous oxide, and this can be achieved by injecting exhaust gas into the inlet manifold. The valve has a valve head operated by the rod which is actuated by a lever. The lever is in turn operated by the connecting rod which is actuated by the accelerator pedal through a hooked end. Depressing the accelerator pedal opens the valve admitting exhaust gas from the pipe into the inlet manifold. To prevent jamming of the accelerator pedal if the valve seizes, the connecting rod has a spring which is compresses under excessive load.

Title: Tiered pallet rack - for inter process storage of printed paper sheets with proximity to machines
Inventor: BUSCH GERHARD
IPC: B65G1/04
Filed: 1975-02-12
Abstract: The vertical storage procedure operates without fork lift trucks. On each side of an elevator there are storage racks. The tiers are tracked for pallet runners to travel between the tiers and the elevator platform. Stops on all tiers retain the runners in position, releasing to permit runner traction when the platform is at a relevant level. The elevator drive motor is interlocked to actuate the platform only if a runner thereon is fully home. Another switching permits unloaded platform working. Space is saved by this arrangement as well as providing a clear over-all view.
Patent DE-2512972-A1 (DE)
Title: Tipper with non jamming flap - has hinges set flat along tipping direction and with spring link in operating levers
Inventor: WINTER LUDWIG
IPC: B62D33/037
Filed: 1975-03-24
Abstract: The side wall of the tipper drops as the load is tipped. In order that the operation can be controlled from the cab the wall is operated by a set of levers (9, 10, 11) linked to the top of the wall (5). The wall is hinged on the chassis by metal strips which are flat over most of the wall, and which are turned edge on to the wall at the bottom (8). This prevents stones etc. from jamming against the strips and blocking the wall when it is swung up again. The bottom edge of the wall is pointed (7) so that the risk of jamming small stones under it is considerably reduced. The tipper can thus be operated with little risk of the wall jamming and being damaged. For added protection the linkage is joined to the wall by a spring coupling (6).
