Title: Load carrier which can negotiate curves - has front slewing travel roller set back from forward end, and bar to absorb tension and compression loads slewing with rear travel roller
Inventor: GRUBE ERWIN
IPC: B65G1/133
Filed: 1977-10-04
Abstract: The load carrier is capable of negotiating curves, being particularly for a monorail hanger conveyor. It is in boxor multi shelf foam, with two travel rollers (3, 4) slewing on a vertical axes (5, 6). The front roller (4) in the travel direction is set back from the forward end of the carrier, so that on a curve this end swings outside it. Where the carrier form a part of a chain it can have a bar-shaped member absorbing both tension and compression loads, and slewing with the rear travel roller, while its forward end is coupled to the rear roller of the preceding carrier.

Title: Dynamically balanced rear suspension for car - has transverse supports linked to moving suspension points in centre of vehicle
Inventor: PUCHAS CHRISTIAN
IPC: B60G3/26
Filed: 1977-10-29
Abstract: The rear suspension is braced by transverse supports (5) which are linked in the middle of the vehicle by swivel joints (17) set on the middle of the torsion bar (14). The torsion bar is bent forwards near the middle so that that point moves with the suspension deflections. The suspension is thus dynamically balanced with axle loadings without requiring a large vertical space. It is suited for compact cars and provides additional stability for cornering.

Patent DE-2908789-A1 (DE)
Inventor: PFLAUM AUGUST
IPC: B65H27/00
Filed: 1979-03-07
Abstract: A guide roller having a roller casing (1) for guiding a paper web in a rotary printing machine is arranged rotatably on a shaft (41) via two rings (2) and bearings (3). The bearings (3) and the rings (2) are arranged axially offset by more than one bearing width (b) from the end face (11) of the roller casing (1) in the direction of the middle of the roller casing (1). As a result, the subcritical speed range is increased considerably as a result of both the reduction in the bearing spacing and a lower weight of the guide roller, itself made possible by shortening the bearing spacing. Furthermore, greater resistance is thereby opposed to the sag, that is to say a considerably more favourable bending line is obtained. <IMAGE>

Title: Mould closure system in injection moulding optical lenses - where final pressure compresses system to give exact cavity size
Inventor: HUENTEN WERNER
IPC: B29C45/56
Filed: 1979-04-07
Abstract: Mould closure mechanism, in injection moulding plastics, has a lever system and pressure cushion which first almost close the mould, polymer is then injected into the cavity, and the tools are finally fully closed by raising the hydraulic pressure on the cushion to a set value. Before injection, the pressure is raised to a first level to bring the mould tools into position, pressure above that to open the mould then closes it; after injection the pressure is raised further by elastic yield of the mould tools so as to reduce the cavity size exactly by the desired amt. Produces very accurate size mouldings e.g. optical lenses with uniform refractory index.

Abstract: The root crop harvesting machine is esp. used for beet. It has a device which digs up the crop or picks it up from the soil and a conveyor to transfer the crop to a collection bunker. A good level of fill is obtained by a stepped relative motion between the shaker cone and the transfer point. The collection bunker (2) is connected with a control device which, on operation, allows a starting and stopping of a relative movement between cone and transfer point. Economical harvesting of the crop may be achieved.

Title: Multiphase thyristor control circuit - uses converter to synchronise output and auxiliary sawtooth voltages with determined period value
Inventor: HOHENLEITNER FRITZ ING GRAD
IPC: H02M1/084
Filed: 1979-05-30
Abstract: The multi-phase thyristor control system with a control section using six control thyristors forming a bridge circuit, uses firing angle control for each phase. The outputs are fed to an A/D converter to equalise the amplified phase differences using a periodic sawtooth voltage. Conversion is carried out using a common sawtooth voltage and the phase position at a zero position is varied at the input by an amount equal to one sixth of the network period. An auxiliary sawtooth voltage is synchronised with the input so that a pulse train is obtained which has this period. This determines the shape of the sawtooth waveform.

Title: Motor vehicle engine assembly - has supercharger driven at variable speed independently of engine speed
Inventor: KIRSTENPFAD FRITZ
IPC: F02B39/04
Filed: 1979-06-28
Abstract: The engine (1) drives the vehicle through a gearbox (10). At the other side of the engine there is a gear drive (2) to a supercharger (3) in the engine air intake manifold. The last stage of this drive consists of a variable speed gear (11,12). The accelerator pedal (5) controls the quantity of fuel supplied by the fuel pump (4). An extension of the linkage (6,7) from the accelerator adjusts the variable speed gear (12). The linkage is arranged to give greater supercharging at lower engine speeds. This maintains a constant excess air volume and thus increases the engine efficiency. The variable speed drive can also be electric or hydraulic.

Title: Adhesion activator application to light metal - by dipping in electrolytic bath with specified concn. and current cycle
IPC: C25D11/04
Filed: 1979-11-09
Abstract: An adhesion activator layer is produced on light metal parts by dipping the part as the anode in an electrolytic bath which contains at least one water soluble component of glasses in at least 20 percent of the max. possible concentration. The cathode is a conductor which is inert to the components. A current is passed through the electrolyte to form an oxide layer and the voltage is then raised periodically to produce intermittent sparks on the metal surface. This continues for at least 10 sec.

Title: Safety lamp socket with inner insulator - has threaded body with recess having leaf spring and latching cam for insulator movement
IPC: H01R33/96
Filed: 1980-04-11
Abstract: The lamp socket has a protection against touching, when the lamp is unscrewed. The current carrying contact parts, which are accessible, are separated by an insulator longitudinally slidable inside the socket. The latter has a threaded body (7) for retaining the incandescent lamp (8). The body has a recess (10) with a leaf spring (11) having a latching cam (12). During screwing home of the lamp, the leaf spring is pressed against the wall of the socket, which simultaneously releases the insulator (6) held by the latching cam of the leaf spring and also fitted with recesses (23). Thus it is slid, against the force of a coil spring (29), so far axially in the direction of the socket bottom (13) using guide strips (5), until the electric middle contact (14) passes through a bore for contacting the lamp cap centre contact, while the lateral outer contact (15) passes through a recess for contacting the lamp cap threaded part.
