Title: Lime fertiliser prepn. - using wedge-slotted screen for removing fines and oversize
Inventor: LOGES JUN HEINRICH
IPC: C05D3/00
Filed: 1980-03-31
Abstract: Lime is prepared for manuring purposes to a consistency where it is free-running and suitable for spreading by passing it over a special screen to remove the dust and fine particles as well as the oversize particles.The screen has wedge-shaped openings, achieved by laying steel ropes or flap bars on edge into the slots of cross bars with a serrated top at different pitch. This prevents clogging of the spreader openings by fine lime which attracts most of the moisture. It also eliminates lumps which have a lower fertilising efficiency.

Title: Pressure cooker with adjustable pressure set by screw-on cap - has pressure-indicating pin always emerging by same distance for easier monitoring
Inventor: BECHT ALEXANDER
IPC: A47J27/09
Filed: 1980-07-17
Abstract: The closure spring (2) holds the valve body in the closed position against the valve seat. There is a resetting spring (3) which acts on the pressure-indicating cooker pin (4). They are each supported on a screw face (16,17) of the cao (8) whose pitches are measured so that as the cap (8) rotates relative to the valve socket thereby setting the bias of the closure spring the ratio of the resetting forces of the closure spring (2) and resetting spring (3) remains constant. The system ensures that the pin emerges by the same length from the upper opening of the cap at any cooking stage so that to monitor the cooking process only a single marking which is the same for each cooking stage has to be observed.

Patent DE-3142093-A1 (DE)
Title: Low-cariogenic sweeteners
Inventor: TAKAZOE ICHIRO
IPC: A23L27/30
Filed: 1981-10-23
Abstract: The sweetener prepared by adding palatinose to sucrose is a low-cariogenic sweetener since palatinose is not only low-cariogenic itself but also inhibits the formation of insoluble glucan from sucrose in the oral cavity. Since the sweetener is virtually identical to sucrose with regard to sweetening power, dissolution capacity in the mouth, palatability etc., and moreover low-cariogenic when used in foodstuffs, it is suitable as a sweetener. Since, furthermore, the sweetener is usually in crystal or powder form, it is easy to handle.

Filed: 1981-12-11
Abstract: Heating installation with a heating circuit (18) which interacts with a gas-fired or oil-fired heating boiler (14), a service water circuit (24) and, interacting with the latter, a heat recovery aggregate (16) consisting of a refrigerating medium (Freon 12) pump (68), a heat exchanger (60), condenser (70) and evaporator (10). To increase the degree of efficiency of the heat recovery aggregate (16) and for better utilisation of all the energy used, the evaporator (10) is arranged in the flue gas take-off (12) of the heating boiler (14), there being provided in the flue gas take-off (12) in front of the evaporator (10) an opening (30) leading into the environment (heating space or the like), which during operation of the heating boiler (14) can be closed by a room air flap (32). For still better utilisation of all the energy, the evaporator (10) is connected downstream of a flue gas heat exchanger (Economiser 34), in the flue gas take-off (12), which is part of the heating return run (20) and by the cooled return run water of the heating circuit (18) which is preheated before it passes into the heating boiler (14). Heating circuit and service water circuit can be separate from one another or directly fluidally connected. Of crucial importance, however, is the coupling between heating and service water system via the evaporator (10), arranged in the flue gas take-off, of the heat recovery aggregate (16) assigned to the service water circuit (24). <IMAGE>

Title: Process for the false-twist texturing of chemical fibres
Inventor: DAMMANN PETER DIPL ING
IPC: D02G1/08
Filed: 1982-06-24
Abstract: In a process for false-twist texturing, the yarn consisting of synthetic continuous filaments is guided through between two continuously rotating parallel surfaces which form a friction false twister and which clamp the yarn between them. The friction false twister is arranged between an entry delivery unit and an exit delivery unit. The yarn tension between the friction false twister and the exit delivery unit is set by the adjustment of different rotational speeds or rates of revolution of the friction surfaces, in such a way that no periodic fluctuations of yarn tension or only fluctuations of yarn tension with a fluctuation time of less than 3 seconds occur. Fluctuations of yarn tension in the texturing zone result in a low texturing quality, and differences in yarn tension from one texturing station to another signify irregularities of the yarns produced at the individual stations relative to one another and therefore a lower quality of the production as a whole.
Patent DE-3226886-A1 (DE)
Title: Single-wheel suspension for motor vehicles
Inventor: GESSNER FRIEDER
IPC: B60G15/06
Filed: 1982-07-17
Abstract: The invention relates to a single-wheel suspension for motor vehicles, having a telescopic shock absorber which serves as a wheel guide and of which the upper mounting on the body is obtained by means of a rubber element fixed indirectly or directly to the body and surrounding a sleeve, a rod-shaped fastening part of the shock absorber being received in the sleeve and being held by axial clamping by means of a threaded connection. To achieve a simple adjustability of the wheel camber, the inner contour of the sleeve is made in the form of a long hole. In order, at the same time, to make the upper mounting of the shock absorber more flexible in the longitudinal direction of the vehicle than in the transverse direction, the outer contour of the sleeve is made essentially oval, whilst the outer circumference of the rubber element is circularly symmetrical.
