Title: Removing wax from new steel cables with hemp core - where cable travels through cleaning blades mounted on rotary carrier
Inventor: STEINERT ERWIN ING GRAD
IPC: D07B7/16
Filed: 1974-10-29
Abstract: Device for the cleaning of steel cables, esp. steel hoist- or traction-cables made from multi-strand steel cable with a hemp core, the novelty being that the cable is surrounded by two semi-circular ring elements forming a holder for a two-part split dish supporting a split ball thrust bearing; the bearing is used to house a split carrier which leaves only a small clearance round the cable, and a cleaning blade is mounted on the carrier. The ring elements are pref. bolted on angle-iron supports which also carry scraper blades, whereas the cleaning blade pref. forms a rosette-shaped cavity matching the cross-section of the cable. The hemp core of the cable is usually treated with paraffin mineral wax for long-term flexibility but wax oozing out of new cables interferes with, and fouls, the drive-units, cable-brakes etc. the invention provides rapid and simple removal of the wax seeping out of the cable.

Title: Lamp cap conveyor loading appts - has spring loaded retainer between rotor and stationary guide
Inventor: GRISCHAEW GENNADY IWANOWITSCH
IPC: H01K3/28
Filed: 1975-02-21
Abstract: The mechanism loads lamp caps into the cells of an end less chain conveyor (the mechanism is designed for use in a lamp cap smearing installation). In this mechanism, between a rotor, which carries lamp caps to the cells of the chain conveyor, and a stationary guide arranged to accumulate lamp caps are fitted a spring-loaded retainer and a means for positively moving lamp caps from the stationary guide into the rotor slots. The spring loaded retainer prevents the lamp caps from leaving the guide and periodically, when a lamp cap is fed into a rotor slot, is positively moved out of the retaining position. This constructional arrangement provides for sure feeding of lamp caps into the conveyor cells practically at any conveyor speed.

Title: Glass plate stacking device - with suction lifting head and attached variable pressure touch sensor
Inventor: KLAUS KARL-HEINZ
IPC: B65H7/16
Filed: 1975-04-17
Abstract: Device for stacking and lifting plates, esp. glass sheets, comprises >=1 sucker operated by a jack which moves towards a stack of plates together with a feeler which releases an impulse causing movement of the shaft of the piston when it touches the stack of plates, the height of which varies on loading or unloading a plate.

Title: Roller bearing cage with anti-corrosion coating - has nickel layer applied to steel surface by heating under gas or in vacuum
Inventor: PREEN WOLFGANG VON DR
IPC: F16C33/44
Filed: 1975-12-17
Abstract: The roller bearing cage is of non alloyed or slightly alloyed steel, into the surface layer of which nickel is diffused. To achieve this, after the mechanical machining of the cage, a nickel layer is applied by means of a galvanising process. The cage is then heated to a temp. under protective gas or in a vacuum at which the nickel layer is diffused partly into the base material. The gas can be so adjusted that it causes carbonisation, so that carbon is diffused into the base metal at the same time as the nickel. The time during which the diffusion temp. is maintained is determined by the depth to which the diffusion is required to be achieved.

Patent DE-2619744-A1 (DE)
Inventor: SCHARF FRIEDRICH DIPL PHYS DR
IPC: F24V50/00
Filed: 1976-05-05
Abstract: The method uses fossil primary energy via an additional heating system (17), solar energy via a solar collector (12) and environmental heat via an air heat exchanger (13). These energy sources take over, individually or in combination, according to the quantity of energy arising, the heat supply. The method also makes use of a heat pump (16) and a heat accumulator (15), e.g. a latent-heat accumulator. The heat accumulator (15) is charged by the solar collector (12) when a surplus of solar energy is available, or when, in the case of incapacity of the solar collector (12) for direct heating, the heat requirement is covered by the heat pump (16), where appropriate together with the additional heating system (17). The additional heating system (17) which consumes the fossil primary energy is only switched in when the heat requirement cannot be covered by the solar energy, the environmental energy and the energy stored in the heat accumulator (15), where appropriate with interconnection of the heat pump (16). As a result, it is possible to limit the consumption of fossil energy. <IMAGE>

Abstract: The building panel made of highly heat-insulating material, such as hard foamed plastic, perlite or vermiculite, has an uneven surfacing and/or a lining on one or both sides. Set between load bearing masonry and its external cladding, it provides hollow rear-ventilating spaces, without involving precautions against accidental spillage of mortar into these. The panels heat-insulating body has depressions on one side, running continuously from top to bottom and bounded by protrusions.

Title: Pressure vessel safety valve preventing refilling - has sealing device bearing against edge between two bore sections
Inventor: WALKER ROBERT
IPC: B65D83/14
Filed: 1976-10-08
Abstract: The pressure vessel safety vavle prevents refilling, and has a housing (108) with central bore (112, 124) connecting the mouth to the pressure vessel (100), the lower part (112) of the bore being narrower than the upper (124), for filling and emptying the vessel. A sleeve with an internal thread (180) screws onto the housing, and when the latter is screwed for the max. distance into the sleeve a sealing device (132) bears against the edge formed between the upper and lower parts of the bore. It also does so when refilling is attempted after emptying. A centre piece (116) with a central bore fits in that of the housing, and the sleeve (176) rotates, but cannot slide axially, in relation to this piece. In the latter there is a passage from its own bore (120) to the lower part of the housing bore, outside the sealing device, which slides in the lower end of the centre piece bore, in which there is a stop to prevent it coming free.
