Title: Coin deposit shopping trolley limit mechanism - blocking use of deposit system beyond limit
Inventor: FUCHS PETER
IPC: G07F7/06
Filed: 1991-11-19
Abstract: The system for limiting the length of shopping trolley rows where a coin deposit system is used, consists of trolley aisles (1) made of angle iron or similar and a control mechanism (2). The control mechanism is contoured to match the profile of the coin deposit system on the right of each trolley, and while permitting movement of the trolley in and out of the row, blocks use of the coin deposit system within its boundary. This results in a limit to the length of trolley row (5).
Patent DE-4141069-A1 (DE)
Inventor: SCHMID RAIMUND DR
IPC: C09C1/28
Filed: 1991-12-13
Abstract: In order to produce glossy pigments based on platelike silicate substrates provided with several coatings, the substrates already coated with a first layer of colourless or selectively absorbing metal oxide are (a) at first coated with a second, non-selectively absorbing layer essentially composed of carbon, metal and/or metal oxide, and then (b) are coated, if required, with a third layer of colourless or selectively absorbing metal oxide. The carbon layer (step a) is applied by thermal decomposition of oxygenated hydrocarbons which contain at least one oxygen atom for each pair of carbon atoms. The metal layer (step a) is applied by gas phase decomposition of volatile compounds of said metals in an inert gas. The metal oxide layer (steps a and/or b) is applied by gas phase decomposition of volatile compounds of said metals in the presence of oxygen, steam or mixtures thereof. In case (a), said layers are applied on substrates already coated with a first metal oxide layer and in case (b), said layers are applied on substrates coated with a second, non-selectively absorbing layer (a). Also disclosed are special pigments, the production and use of such glossy pigments for colouring lacquers, printing inks, plastics, decorative cosmetic compositions, glass and ceramic products.
Patent DE-4200922-A1 (DE)
Inventor: BENZ WILLI
IPC: B21D1/02
Filed: 1992-01-16
Abstract: In a method for straightening plates in which the plate is fed through straightening gaps formed by a plurality of adjustable upper and lower straightening rollers (12, 15) and set to correspond to the cross-section and nominal strength of the plate and, after initial maximum deformation, is then bent several times in opposite directions with large reductions in the degree of deformation, improved operation is obtained if the straightening region of a straightening machine is enlarged to encompass thicker plates by using a smaller number of straightening rollers (12, 15) in engagement and thus a higher roller pitch in the case of plate thicknesses which go beyond the nominal plate thickness of the straightening region. <IMAGE>

Title: Method of emptying acetylene-cylinder groups and arrangement for carrying out the method
Inventor: HAMMER KLAUS-UWE DIPL ING
IPC: F17C13/04
Filed: 1993-03-19
Abstract: The invention relates to a method of emptying acetylene cylinders and acetylene-cylinder groups from which extraction is effected individually until an "empty indication" with following change-over to the next cylinder or the next cylinder group. In order to achieve better emptying of the cylinders, it is proposed that, after an empty indication and change-over to a still productive cylinder group and after a regeneration time has expired, the operation be switched back to the preceding cylinder or the preceding cylinder group to which the empty indication referred. To this end, in an arrangement for carrying out this method with two acetylene cylinders or acetylene-cylinder groups and with means for the alternative connection of a cylinder or a cylinder group, it is proposed that a stored-program control be connected at least to devices testing at least the line pressure and to means for the alternative connection.

Title: Melting aluminium@ alloy scrap - with vortex motion of liq. melt produced by means of a magnetic field generator
Inventor: SATO YASUSHI
IPC: C22B21/06
Filed: 1993-04-23
Abstract: A rotating force is applied to molten metal held in a cylindrical chamber, so that it causes, through the effect of the resulting centrifugal force, the metal to rise along the inner surface of the chamber. At the same time, the liquid surface of the metal is caused to assume the form of a parabola, so that a vortex is generated in the molten metal. Al alloy scrap is introduced into this vortex. The installation comprises a furnace body, a cylindrical region for entry of the charge material, and a device located along an outer wall of the region, for generation of a magnetic field. The cylindrical entry region is incorporated into or connected to the furnace body so that the molten metal circulating in the furnace body flows into the cylindrical entry region. USE/ADVANTAGE - In the metallurgical industry. In comparison with known alternatives, the plant involved is simpler and less energy consuming, with its efficiency not critically dependent on the constructional accuracies.

Title: Removable and damage-free fastening device on riding saddles for bags, blankets, riding coats etc.
Inventor: DANY WOLFGANG
IPC: B68C1/20
Filed: 1993-06-28
Abstract: Virtually all commercially available riding saddles for dressage, jumping and general purpose use offer no possibility for fastening things like rain jackets, horse blanket, first aid kit etc. If it is desirable to carry these things, it is necessary subsequently to screw holding devices on the saddle, as a result of which the saddle tree and the upper leather are damaged permanently. Screwing on and thus the damage can be avoided with the removable fastening device. The fastening device consists of a wire bow into which three holding devices are integrated and which is connected to a plastic hook by an approximately 40 cm long flat rubber band. The wire bow is clamped behind the saddle, the rubber band pulled forwards on the saddle underside, and the plastic hook is hooked in at the front of the saddle. The removable fastening device is suitable for all commercially available dressage, jumping and general purpose saddles.

Abstract: In a device (12) for feeding a refuse-sorting plant (10) with the contents of refuse bags, a feeder device (14) for the refuse bags is followed by an obliquely ascending conveyor track (16) which is suitable for supporting and transporting refuse bags and their contents and which terminates at its upper end above the feed point of a conveyor traversing the sorting region. Arranged above the conveyor track (16), near its upper end, is a deflector rake (22) which is pivotable about an axis (30) spanning the conveyor track (16) and the prongs (32) of which approach one another obliquely downwards opposite to the conveying direction of the conveyor track (16), in a receiving position of the conveyor track (16), and can be moved out of this receiving position opposite the conveying direction into a throw-back position lifted off from the conveyor track (16). The deflector rake (22) can be driven in a movement going to and fro between the receiving position and the throw-back position. Tearing-open devices (40) assigned to the refuse bags extend from a mounting (34) following the deflector rake (22) in the conveying direction, so as to engage through the interspaces between the prongs (32) and increase their distance from the conveyor track (16) opposite to the conveying direction, the said tearing-open devices (40) being jointly pivotable out of a basic position counter to a restoring force about an axis (36) spanning the conveyor track (16), the conveying movement along the feeder device (14) being regulatable in dependence on the angular position of the tearing-open devices (40) in relation to the basic position. <IMAGE>
