Patent DE-3706645-A1 (DE)
Title: Heat exchanger
IPC: F28F13/14
Filed: 1987-03-02
Abstract: With the invention a heat exchanger with at least one heat exchanger surface consisting of material with high heat conductivity and impacted on both of its surfaces by exchange fluids of different temperatures, which heat exchanger surface in its extension transverse to the desired heat transfer is subjected to a temperature gradient, is improved in such a way that the heat exchanger surface on at least one partial area of one of its surfaces is covered by a protective layer of a material of low heat conductivity. The heat conduction resistance of the protective layer in the direction of the temperature gradient is different in such a way that the temperature gradient is essentially equalised or at least kept within specified limit values.
Patent DE-3712357-A1 (DE)
Title: Self-clamping clamping head for receiving a bobbin
Inventor: BESEMANN ALFRED
IPC: F16D1/06
Filed: 1987-04-11
Abstract: A self-clamping clamping head for receiving a bobbin (17) consists of a plurality of clamping segments (6) which are operatively connected via driving and spreading elements (7, 8, 9, 9a, 9b, 12, 12a, 12b) to two threaded nuts (3, 4) movable in opposition on a central threaded spindle (2). With the threaded spindle firmly braked, a torque exerted on the clamping segments from outside brings about an opposed movement of the threaded nuts on the threaded spindle and, as a result of the effect of the wedge faces of the spreading elements, a radial movement of the clamping segments towards the inner face of the bobbin tube. <IMAGE>
Patent DE-3712819-A1 (DE)
Title: Safety gas compression spring
Inventor: OTTO GUENTHER
IPC: A47C3/30
Filed: 1987-04-15
Abstract: In a known safety gas compression spring, a single non-return valve for letting off a dangerous overpressure in the event of excessively high thrust loading of the spring is provided. To supplement this, the existing overflow valve for length adjustment of the spring can here be constructed as a second non-return valve in case of overloading in the tension direction. This design is relatively elaborate and expensive. The novel gas compression spring is to be simpler and less expensive and meet high safety requirements. The novel gas compression spring is characterised by a second non-return valve (4) which is arranged in or on a further overflow channel (40) likewise in the piston (2), acts in the opposite direction to the first non-return valve (3) and is intended for pressure equalisation between the two cylinder spaces (14, 15) upon compression of the compressed gas in the other cylinder space (15) beyond a pressure threshold value. The safety devices of the spring are arranged concentrated on the piston and can be constructed simply and symmetrically, i.e. with the same components. The gas compression spring is thus less expensive and can be manufactured simply in various versions. The gas compression spring is to be used, in particular, for lifting devices for the continuous adjustment of table tops, chair seats, armchair backs and the like. <IMAGE>

Particularly suitable in a television receiver for mounting a loudspeaker enclosure (1) which matches the shape of the picture tube.
Patent DE-3741792-A1 (DE)
Title: Method for reducing the programme cycle times, especially in domestic washing machines
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F34/30
Filed: 1987-12-10
Abstract: In known washing machines, in a laundry-loosening phase the laundry articles are newly distributed by means of laundry-correcting cycles, so as to reduce the laundry unbalance, during the spinning programme before the actual spin-up. The duration of the laundry-loosening phase is the same for all types of laundry, loading quantities or washing programmes and is often needlessly long. The object of the invention is to adapt the number of laundry-correcting cycles to the abovementioned parameters and thereby reduce the entire washing-programme cycle time. The number of laundry-correcting cycles which is stored in the electronic programme-control unit is linked logically to the keys of the input keyboard and to the programme sector, so that a highly specific number of laundry-correcting cycles is assigned to each type of laundry, loading quantity and spinning programme. The method is suitable for optimising the programme time in domestic washing machines. <IMAGE>

Patent DE-3803069-A1 (DE)
Title: Brake pad
Inventor: WEIDENWEBER MICHAEL
IPC: F16D55/00
Filed: 1988-02-03
Abstract: The invention relates to a brake pad for a spot-type disc brake which is held and guided in a brake well. Particularly when the brakes are operated only occasionally, the carrier plates for the brake shoes tend to corrode inside the brake well, making operation more difficult. The difficulties which occur may be increased further by the use of a soft metal (aluminium) for the brake housing, for reasons of weight for example. Due to the considerable forces which occur during braking, the guide surface of the well may then be damaged by the hard material of the carrier plate. The selection of different metals increases its tendency for corrosion even further (electrolysis). It is the object of the invention to improve the guidance of the brake pads within the brake wells, especially where the housings are made of aluminium. As a solution, the invention proposes to clad the guide surfaces of the carrier plate with a suitable metal layer. Advantageous further developments of the invention are concerned with the anchoring of the metal layer in the carrier plate and with possibilities for increasing the area of support. <IMAGE>

Title: Tarpaulin frame, in particular for lorries and trailers
Inventor: DIETRICH UDO
IPC: B60J7/10
Filed: 1988-04-15
Abstract: The known tarpaulin frames are assembled following a module-type of construction principle from the individual tarpaulin-frame parts, namely stakes with receiving pockets for the insert laths, bows and longitudinal roof struts. Production of the tarpaulin frames is expensive since the individual frame parts cannot be prefabricated in series. The weight of the tarpaulin frames made of iron profiles is, moreover, very high. The intention is to be able to assemble the novel tarpaulin frame from series-produced profiled parts in accordance with the dimensions desired by customers. The stakes (2), bows (5a, 5b), longitudinal roof struts (6a, 6b) and optionally the insert laths (4) of the tarpaulin frame (1) are designed as telescopic tubes and are made of light metal. The tarpaulin frame is suitable for lorries and trailers of all makes on the market. <IMAGE>

Patent DE-3837147-A1 (DE)
Title: Flowmeter for fluids of low viscosity
Inventor: MARTENS JOERN
IPC: G01F1/36
Filed: 1988-11-02
Abstract: Flowmeter for fluids of low viscosity, having two pressure controllers (1, 4) which are connected together via a connecting tube (3), of which the second (4), seen in the direction of flow of the fluid, actuates a pointer (7), whose displacement distance is a measure of the volume flow (D), via its valve shaft (5) and a linkage (6). The pressure controllers hold the exit pressures (pa1, pa4) constant. The displacement of the controller (4) therefore corresponds to the volume flow (D) through the device. The displacement distance (L) of the valve shaft (5) is detected as a measure of the volume flow by means of a sensor (8) and indicated by a measuring electronic unit (10) as a total quantity on the indicator display (11). A (safety) mechanism (27), which is actuated electromagnetically, depending on the displacement distance (L), shuts off the gas flow in an emergency (gas failure safety, safety in the case of conduit breaks). <IMAGE>

Title: Guide, including drive for a web made of paper or board
Inventor: BEISSWANGER RUDOLF
IPC: D21F7/02
Filed: 1988-12-06
Abstract: In the guide, including drive for a material web made of paper or board, a fixed point having a fixed rotational speed is produced by guiding the web with a large wrap angle over at least one hollow roll which is provided with holes in the cover and generates a low pressure. By this means, in the wrap region of this roll 1, the web is coupled to it firmly, so that the rotational speed can be adjusted very accurately. This is further improved by coupling together either two hollow rolls 1, 2 or one hollow roll and one neighbouring deflection roll of correspondingly large diameter via a transmission 4 to 7. In this case, a correspondingly large wrap angle of the material web W is to be provided around the rolls coupled via the transmission. Application is mainly foreseen in coating installations for webs of paper or board. <IMAGE>
