Patent DE-3103383-A1 (DE)
Title: Device for limiting the axial displaceability of a floating caliper relative to a carrier of a pin-guided floating caliper disc brake
Inventor: STOKA ROBERTO
IPC: F16D55/2265
Filed: 1981-02-02
Abstract: The invention provides a device which prevents the guide pin (3) from being withdrawn completely from the hole (2) during the servicing of the brake, in particular during the changing of the brake shoes. This ensures that the sliding behaviour is not impaired, for example by dirtying of the sliding surfaces of the pin (3) and the hole (2). The device consists essentially of two stops, which strike against one another when the pin (3) is moved outwards in the hole (2). In Fig. 1, one stop is formed by the side wall (21) of the groove (17) in the hole while the other stop is formed by the side wall (15) of the spring ring (6) secured on the pin (3) in a groove (13); in the relaxed condition, the spring ring (6) has a diameter which corresponds to the diameter of the groove (17) and thus ensures mutual abutment. In the push-in direction, the ring (6) is compressed by chamfers (5, 10) to the diameter of the hole and, as a result, there is no stop in this direction. <IMAGE>

Title: Priming composition for surfaces made of cement mortar or concrete
Inventor: SAKATO NAOYUKI
IPC: C08L31/04
Filed: 1981-02-20
Abstract: The priming composition contains as essential constituent, dissolved in an aqueous medium, a modified polyvinyl alcohol etherified in the side chains by long-chain alkyl groups in defined molar proportions, in particular by lauryl groups or stearyl groups. The priming composition can additionally contain a synthetic resin emulsion, in which case the synthetic resin of this emulsion consists at least essentially of vinyl acetate. Owing to the high effectiveness of the modified polyvinyl alcohol, an adequate priming effect is achieved when the modified polyvinyl alcohol is present in a concentration as low as 1% by weight, based on the total solids content of the priming composition, the remaining solids content of the priming composition being accounted for by the synthetic resin of the added emulsion. The priming composition improves the adhesion of inorganic mortar coatings on concrete and cement mortar surfaces and improves the water-barring properties of such coatings.

Title: Pneumatic door drive with a reversing switch device
Inventor: KLATT ALFRED
IPC: E05F15/41
Filed: 1981-02-27
Abstract: Pneumatic door release for pneumatically actuable doors, especially pivoting or folding doors in vehicles serving for passenger transport, are provided with a reversing switch device triggerable by mechanical means and converting the door-closing movement into an opening movement when persons or objects are jammed in a closing door. Since the door, when it reaches the end position, comes to a stop by striking, the same effects as when a door strikes against a person can occur, with the result that there is the possibility that a reversal of the door movement out of the end position can take place in exactly the same way as a reversal when the door comes up against a person or an object. In order to prevent such a reversing movement of the door out of a closing or opening end position, mechanical means have been provided according to the invention.
Patent DE-3118826-A1 (DE)
Title: Gauge roll for feeding rod-shaped material
Inventor: WENGENROTH KURT
IPC: G01B7/04
Filed: 1981-05-12
Abstract: In the dimensionally accurate feeding of rod-shaped material to a shear, errors can arise because after each cut the rod material that has not as yet been cut rebounds as a consequence of the elastic forming energy, it being possible for the material to slip through under a pressed-on gauge roll. During the following conveying operation, a feed is simulated in that the material firstly runs forward again with its leading edge up to the mouth of the shear. In order to avoid such a setting error, the invention provides a gauge roll that rotates in braked fashion and an easily rotating pressure roll, which is independent from said gauge roll and is capable via a stop of driving along the gauge roll, which is provided with a dog, in the conveying direction. When the pressure roll then runs back under the effect of the impulsive rebound, it runs back empty without driving along the gauge roll. During the next feed, the material of the leading edge runs forward up to the start of the mouth of the shears without the gauge roll being driven along. It is only from this point on that the gauge roll is driven along and then displays a reliable measured value.

Patent DE-3132949-A1 (DE)
Title: Machine for producing mouldings from plastic granules and/or composite material granules
Inventor: GOEHRING KARL DIPL ING
IPC: B29C31/04
Filed: 1981-08-20
Abstract: A machine for producing mouldings from plastic granules and/or composite material granules is described, in which the plastic granules, to which fillers may be added if appropriate, are compressed under the effect of two counteracting plungers. The mould cavity and the interior space of the cylinder located between the two plungers have previously been evacuated, so that there are no problems as a result of air displacement. The surfaces of the granules are then plasticated under the effect of heat between the two plungers, the evacuation being continued. In this manner, a devolatilisation of the granules, effected by the heat, is made harmless. After compaction of the superficially plasticated granules between the two plungers, the preform thus produced is slowly pressed, via a large-surface-area press-in opening, into the mould cavity of the casting mould with the further travel of one piston and return travel of the other piston. The evacuation of the mould cavity is set at a specific degree of filling by closing a corresponding valve. The superficially molten layers of the granule bodies solidify again in the mould cavity, during which they are held under pressure by the compression plunger. The mouldings thus obtained, which can be produced with any wall thicknesses, have outstanding homogeneity without air inclusions and gas inclusions.

Title: Process for the adsorptive purification of a gas stream from vapour-form or gaseous impurities
Inventor: WINTER KARL DIPL PHYS
IPC: B01D53/04
Filed: 1982-08-28
Abstract: To purify a gas stream from vapour-form or gaseous impurities in a two-layer or multi-layer sorption filter with the lowest possible energy consumption, the gas stream to be purified is passed through the sorption medium layers connected together in parallel, until the sorption medium layers are exhausted. To recover their absorption capacity, the sorption medium layers are regenerated, a gaseous desorption agent passing through the sorption medium layers connected together in series. It is particularly advantageous, as the desorption proceeds, to remove initially the first, then the second layer and so on from the desorption agent circulation. The process can be carried out in a corresponding manner for the cooling following the desorption.
