Patent DE-3016260-A1 (DE)
Title: Temp. control system for hot air baking oven - has temp. selector switch for baking or roasting, coupled to switch for blower speed control
IPC: F24C15/00
Filed: 1980-04-26
Abstract: The system adjusts different temperatures and blower outputs in a baking and roasting oven, using interconnected switchgear. The switchgear for the temp. selection is so coupled with that of the blower speed that at temp. adjustment for roasting a low blower speed is engaged. This speed is such that no fat swirling takes place. When switching a temperature above 240 centigrades at the end of the roasting programme, an increased blower speed is engaged. The device for this temp. control comprises a temp. sensor (8) in a cooling sleeve, which is so connected to a change-over switch for the blower speed (5) that the speed reduction in the roasting range is cancelled, at least partly, when the temp. of the atmosphere air in the cooling sleeve has exceeded a preset limit value. The roasting range is pref. between 180 and 240 centigrades.

Title: Underground heat extraction cycle for central heating - uses spiked tubes containing water circulating tube, under insulating and waterproof layers
Inventor: GRUBER HEINRICH
IPC: F28D20/00
Filed: 1980-04-29
Abstract: The central heating system for a house extracts heat by using rods buried underground to extract heat from the earth, and combines this with a solar heating system. The heat obtained is used to provide underfloor heating and also wall heating, for interior walls. The water circulating coils are also embedded in outside walls which carry insulating layers. The underground extraction system uses spiked tubes (61) each containing a copper tube bent into a hairpin shape, the spiked tubes being inserted in a pattern over an area. The copper tube bends are interconnected to form a pattern radiating outwards from a collector tube (68) for the water circulating circuit. The area is covered by a heat insulating layer (76) which terminates in a vertical extension (77) enclosing it, and covered with a waterproof layer (78). The spiked tubes are corrosion resistant, and filled with a concrete or cement mass, and are perforated.

Title: Automatic gas density measurement - by determining expulsion time under compression from water via isolating piston
Inventor: ABRAMOWITSCH ALEXANDER
IPC: G01N9/32
Filed: 1980-07-10
Abstract: An automatic gas density measurement device uses the Bunsen-Schilling method which involves comparing the specific wt. of the gas with that of air. It eliminates the errors associated with mixing of the mixing of gas or air with water vapour when water is used to compress them directly. The gas or air is separated from the compressing water by a free piston in a compression chamber connected to the calibrated orifice or nozzle. Iron plates attached to the piston operate inductive proximity switches in the highest and lowest positions of the piston. The arrangement ensures positive isolation of the gas or air from the water. The procedure involves measuring the times taken to expel defined vols. of gas and air in succession.

The cover members are arranged end to end along the base of the wall panel with the yieldable end sections of adjacent cover members being positioned in a juxtaposed relationship with each other. The yieldable end sections enable the cables to be extended from the utility space between adjacent end sections so that only the portions of the yieldable end sections in close proximity to the cables are deformed.
Patent DE-3030954-A1 (DE)
Title: Dynamometer brake for monitoring engine torque - has moving brake part hydrostatic bearings for reduced friction related errors
Inventor: HEINSCHER KLAUS DIPL ING
IPC: G01L3/22
Filed: 1980-08-16
Abstract: A dynamometer brake for measuring torques of engines has rotationally mounted braking components which are deflected by the torque from their initial positions against the force of a spring or gravity. The bearing friction of the moving brake components contributes to measurement errors. This effect is considerably reduced compared to similar devices. The bearing friction is reduced by using hydrostatic bearings (9) operating in both radial and axial directions and supplied with water from the water supply. The throughput of liquid in the hydrostatic bearings of the brake components is limited by the choking effect at cross-sectional restriction points. The moving parts are completely separated from the stationary parts by a thin film of water. Hence the lubricating characteristics of the liquid used are not important.

Abstract: The method of producing emulsions and suspensions with long-term stability is to feed the pre-metered starting components by means of two pumps operated in co-current to a dispersing device. The latter comprises a stationary, conical, toothed outer ring and a conical rotating body which rotates in the outer ring and is provided with teeth to match the teeth of the outer ring. At the same time, an annular grinding gap which tapers in the flow direction towards the outlet cross-section is formed as a result of the conicity of the outer ring and of the rotating body. Cavern-like recesses are formed by the teeth in the lateral boundary walls of the gap in order to produce wall-reflecting, annular turbulence zones. <IMAGE>
Patent DE-3105189-A1 (DE)
Title: Tipping device
Inventor: POHLE HELMUT
IPC: B61D9/08
Filed: 1981-02-13
Abstract: The tipping device for the containers of suspended monorail conveyors for and around mining and tunnelling is intended to ensure that the container rotates in each case only in the predetermined direction during the emptying process and, in this process, tips out the material carried along. This is achieved in that adaptor and suspension gear are connected to one another in such a way that the load point or the load points are arranged at a distance from the central rotation on the edge of the container. For this purpose, adaptor and suspension gear are constructed as discs which are mounted so as to be capable of rotating in one another and can be fixed with respect to one another and whose fixing points are arranged as closely as possible to the edge of the container. Even when the container is loaded inconveniently, a tipping device of this kind prevents the container rotating unexpectedly in the direction of the overload since the lever arm between centre of rotation and bearing point is too large to permit this. <IMAGE>

IPC: F16H61/40
Filed: 1981-12-24
Abstract: Method and device for controlling a motor vehicle power unit consisting of an internal combustion engine and a variable-ratio power divider transmission. For adjusting the output, use is made of the data from the only sensor sensing the speed at the transmission output end, and from the accelerator and brake pedals. The resultant reference value is directly transferred to an engine function generator in which engine characteristics are stored. The output signal from the engine function generator is used to control the throttle or the fuel supply system actuating lever. The reference generator also directly influences a speed function generator, in which the optimum speed is stored. Its output signal is linked with the indication from the sensor so as to form a reference value for the transmission ratio and is processed in a transmission control unit for form actuating signals for the transmission.
