Patent DE-3011694-A1 (DE)
Title: Wear resisting coating, esp. for electric contacts - consists of intermetallic cpds., esp. hard carbide(s), obtd. by sputtering onto contact carrier
Inventor: MENGELBERG HANS-DIETER DR RER
IPC: F02P7/063
Filed: 1980-03-26
Abstract: The contacts consist of a carrier, which is coated on at least one surface by sputtering using a high-frequency plasma. The sputtering target consists of intermetallic cpds., e.g. hard carbides; and is exposed to ions in the plasma so neutral atoms and/or ions leave the target and are deposited on the carrier. The target pref. consists of sintered pressings made of pure or mixed carbides of the transition metals in gps. IVB-VIII of the periodic system. Alternatively, the target may consist of mixts. of metals and/or non-metals which cannot be made by melting; or of intermetallic cpds. sepd. from a molten bath. Masks are pref. used, so only a desired area of the carrier is coated. A very simple method is provided for forming contacts, esp. for low electric currents, where the contacts have a low electric resistance, and do not weld together. The sputtered carbides have a resistance similar to that of hard gold.

Title: Evaporator esp. for solvents has moisture separator - has helical plate in annular space between vessel wall and central tube
Inventor: FUEHRING HEINRICH
IPC: B01D1/12
Filed: 1980-05-21
Abstract: An evaporating vessel, esp. for the sepn. of volatile solvents from mixts. contg. paint, dye etc., has a double-open ended hollow bylinder mounted above the liq. surface and forming an annular space between itself and the vessel wall; this space is closed by a top plate. The gas-liq. mixt. enters this region below the top plate. This annular space contains a helical plate descending from the top plate, causing the mixt. to descend along a helical path down into the vessel. The inlet pipe pref. enters the annular space tangentially. In a variant, there may be a similar helix in the form of a metal strip on the inner face of the hollow cylinder. Used partic. for sepg. very large quantities of vapour from mixts. entering at rates of up to 1000 litres per minute. In such large quantities splashing of the liq. and consequent entrainment of liq. with the discharged vapours is very difficult to prevent. This arrangement provides a more effective, space-saving liq. droplet separator to prevent liq. being entrained by the gases leaving the vessel.
Patent DE-3020656-A1 (DE)
Title: Adsorptive sepn. of combustible materials from gas mixt. - by multiple active carbon stages with interstage cooling of gas
Inventor: BAURHENNE GEORG
IPC: B01D53/04
Filed: 1980-05-30
Abstract: The adsorptive sepn. by active carbon of combustible hydrocarbons and/or solvents from gas mixts. with low (up to 12 vol.%) oxygen content in a multi-stage process involves cooling the mixt. after each succeeding stage to approx. its temp. on entering that stage. The material absorbed at each stage is recovered by known desorption methods, e.g. with steam. Also claimed is the appts., a vertical or horizontal column divided into separate chambers each contg. a body of activated carbon with a free space before and after. From the space following each body of carbon the gas passes to an external cooler and is then returned to the space before the next body of active carbon. Used e.g. for recovering hydrocarbons from the gas emerging on filling fuel tanks, after addn. of inert gas (nitrogen, methane) to reduce explosion risk. Since large volumes of air are not added (as with known systems) the appts. is compact, and the final emission is low in pollution.
Patent DE-3022434-A1 (DE)
Title: Induction motor for controlled variable speed drive - uses magnet ring and detector coils to produce speed feedback signal
Inventor: BUCHER HEINZ
IPC: G01P3/487
Filed: 1980-06-14
Abstract: One end of the motor rotor carries a magnet ring (23) on which a number of equally spaced alternating north-south pole pairs (41,42) are placed. These poles are made of permanent magnet material. Attached to the motor frame are two detector units (40). These are arranged diametrically opposite each other and axially in line with the magnet poles. The coils of the detector units are connected electrically in series. The output is rectified to give a speed feedback signal to the regulator. This feedback assists in setting the phase control to the correct position. The use of a separate speed sensing system eliminates the distortion and noise due to leakage fluxes inherent in the use of a stator winding derived feedback.
Patent DE-3030115-A1 (DE)
Title: Differential amplifier with multiple threshold voltages - employing multi-emitter transistor as one part of amplifier
Inventor: MEYER FRITZ DR ING
IPC: G01R19/17
Filed: 1980-08-08
Abstract: The proposed amplifier is intended for use at frequencies of hundreds of MHz, and is applicable to a digital data processing, in particular, Analogue-to-Digital converters. With increasing frequency the matching of differential amplifiers becomes increasingly uneconomical as the component count increases making integrated circuits more difficult to construct. The present amplifier is intended to overcome this problem. A multi-emitter transistor (T3) with n-1 emitter connections for an n level pulse sequence has its base connected to a reference supply (u(t)). One emitter is connected to the collector of the signal (S) input transistor (T4) and to the emitter of one output transistor (T5). The other emitters of the first transistor (T3) are similarly connected (T7,T6). The output transistors (T5,T6) have their bases connected to the level reference voltages (U1,U2). The output (A) is taken from a resistor (RA) connected to the zero volt reference. Switching points are determined by the relative magnitudes of the reference supply (u(t)) and the level references (U1,U2).

Title: Process for producing a puff pastry bakery product
IPC: A21D13/00
Filed: 1981-03-11
Abstract: The process relates to the production of a puff pastry bakery product. Puff pastry bakery products of the conventional type have the disadvantage that they taste too one-sidedly like a flour dough product and moreover do not satisfy. The proposed puff pastry bakery product avoids the disadvantages and permits the production of highly satisfying puff pastry bakery products of very variable taste which enable in particular the processing of foodstuffs produced locally in large amounts such as chicken farm poultry meat, meat from a large scale animal husbandry or cheese from a dairy. This object is achieved by laying one on the other in any desired sequence one or more ham slices, one or more cheese slices or portions and a portion of meat, in particular poultry meat, on a puff pastry slice, adding a spice mixture, folding over the edges of the puff pastry slice to form a closed casing and baking the puff pastry preproduct at about 220 to 250 DEG C for approximately 20 to 25 minutes in a baking oven and the like.

Title: Device for loading rail vehicles which are combined to form a train behind gallery driving machines
Inventor: KIRCHMAIR GERHARDT DIPL ING
IPC: E21F13/02
Filed: 1981-03-26
Abstract: The invention relates to a device for loading rail vehicles which are combined to form a train. The invention has the object of avoiding the disadvantages of previously used devices, which is achieved in that the traction vehicle which is assigned to the train in addition to the locomotive is a traction vehicle which is located on the front side of the site and is smaller and slower with respect to the locomotive. Manoeuvring with such a traction vehicle takes place without direct support on the rock or the conveyor. Therefore, in comparison with winches attached to the rock or chain transporters, the laborious resetting which impedes operation of the said winches and transporters is dispensed with. Furthermore, the traction vehicle has a working speed which is matched to the size of the load and as a result of its lower height does not impede subsequent clearing of tubbings and track material even in very small galleries.
Patent DE-3115093-A1 (DE)
Title: Harmonica
Inventor: HWANG CHIEN-SHU
IPC: G10D7/12
Filed: 1981-04-14
Abstract: Harmonicas are usually designed as a rectangular bar. During playing, the sounds are produced directly when the player breathes out or in through his mouth which bears closely against the tongue plate base. To change the sounds, the player can change the position of his mouth which bears closely against the tongue plate base, and thus he must move the harmonica laterally in order to change the position of his mouth which bears closely against the tongue plate base. During playing the harmonica according to the invention, however, the mouth of the player remains unchanged in the position of the airtight device on the harmonica and the notes are changed by changing the position of the tongue plate on the airtight housing by means of the sound-changing handle. The external appearance, the playing action and in particular the structural form of the harmonica according to the invention are thus completely different from those of conventional harmonicas.

Title: Circuit arrangement for triggering a switching process which is dependent on rotation speed
Inventor: SCHEMITZEK ERICH
IPC: F16H59/36
Filed: 1981-06-19
Abstract: A circuit arrangement is proposed which is used for triggering electrical switching processes as a function of the rotation speed of an internal-combustion engine. The circuit arrangement comprises two series-connected monostable multivibrators, each of which is formed from a timer (19, 33) and a comparator (27, 35). A switching stage (38) is connected to the output of the second comparator (35), and feedback is connected to the input of the first comparator (37). The timers (19, 33) are connected to the first input of the comparators (27, 35), whose second inputs are connected to a voltage divider by means of which the switching threshold of the comparators is set. As a result of this construction, a rotation-speed switch can be produced having high switching accuracy, with the individual switching elements permanently fitted for economical mass production, which permanent fitting of the individual switching elements can be used for overrun fuel cut off, rotation-speed limiting, sudden shifting of the ignition timing and for changing gear (gear shifting) with an internal-combustion engine. <IMAGE>
