Patent DE-2054532-A1 (DE)
Title: Single crystal pulling technique - with concentric and subsequently eccentric hf heating coil
IPC: C30B15/14
Filed: 1970-11-05
Abstract: The crystal pulling can be improved by melting the upper zone of a rotating polycrystalline semiconductor bar by a concentric HF inductor coil and by shifting the latter to an eccentric position over the face. This ensures uniform melting. Crystal pulling can begin after a seed crystal has been brought into contact with the molten surface. As the dia. of the extracted single crystal grows, the coil is returned to its concentric position.

Title: Copper-plated aluminium wire prodn - with cross-section reduction effected to form diffusion layer between copper and alumini
Inventor: STEIN DIMITRI R
IPC: B21F19/00
Filed: 1971-10-26
Abstract: The wire is formed in the usual way but is reduced in cross section either by pref. 80% without application of heat or by >=50% a pref. 400 degrees C to induce the formation of a diffusion layer between the Cu and the Al.

Title: Sprung vehicle driving seat - has double shear arms and torsion spring adjustable by moving arms under screw thread
Inventor: WANSCHURA ERNST
IPC: B60N2/02
Filed: 1973-07-13
Abstract: The driving seat is supported by shear arms lined to the base by a fixed point at one end and running in a slide at the other.

Title: Sorting paper and plastics foil from rubbish - uses comminution, spreading, dusting with iron powder and magnetic separation
Inventor: MOTEK HERBERT
IPC: B03C1/01
Filed: 1973-10-01
Abstract: Paper and plastics foils are sorted from rubbish by comminution, spread out and a dusting with iron powder, followed by exposition to the action of a magnetic field. Preferably the rubbish is first comminuted in a beater mill and metal parts separated. It is then spread out on a conveyor belt and subjected to impacts or shaking before the iron powder is applied. After powder dusting, the rubbish is dried by an infra-red or similar dryer before exposure to the field of the magnetic separator. Adhesive liquid may be sprayed on before the iron powder, and it may be suspended in distillation tails.

Title: Refuse compactor with retractable refuse container - has ram plate with raised edge for preventing catching of large tins
Inventor: HERMEIER WERNER
IPC: B30B9/30
Filed: 1973-10-23
Abstract: The ram plate has an upwards turned rear wall in order to ensure that tins are not trapped on the edge of the ram plate. If trapped the tins are lifted up together with the ram and the refuse container collides with the lifted tin so that it cannot be pulled out from the refuse compactor. The turned over edge is at least one fifth of the height of the refuse collection chamber and the side walls of the ram plate are also turned upwards. The compacting press has a retractable refuse container and the compacting ram has a compacting ram plate which comes into contact with the refuse to be compacted. This arrangement ensures that the compacted refuse remains in the refuse container when the ram plate is retracted from the refuse container.

Title: Antilipolytic medicaments contg. thiophene derivs - with a thioalkanoic acid, thioalkanol or thioalkanal-acetal gp.
Inventor: AHRENS HANNS DR
IPC: C07D333/34
Filed: 1974-05-21
Abstract: Antilipolytic medicaments contain thiophene derivs. of formula (I):- (where one of R1-R4 is Rx, 0, 1 or 2 of R1-R4 are Ry, and the rest are H; Rx is -S-CHR5-COOH, -S-CHR5-CH2OH or -S-CHR5-CH(OAlk)2, where R5 is H or 1-6C alkyl and alk is 1-4C alkyl; Ry is 1-6C alkyl, 1-6C alkylthio or CHO), or enantiomers and/or salts thereof, opt. in combination with conventional additives and carriers. The medicaments inhibit the prodn. of free fatty acids (FFA) due to lipolysis in the fatty tissue, and are thus useful for the treatment of arteriosclerosis (by suppressing the conversion of FFA into triglycerides in the liver) and diabetes mellitus (since FFA interfere with glucose utilisation). Unlike known natilipolytics, they are not subject to tachyphylaxia (loss of activity on repeated administration) or the rebound phenomenon (increase in FFA levels after initial lowering), and they have no effect on the heart frequency.

Title: Electric controlled steam generating room humidifier - has automatic electric water level control valves
Inventor: NALINI LUIGI
IPC: F24H1/00
Filed: 1974-09-10
Abstract: The system uses a water tank with water supply and drain pipes controlled by taps or valves. Two spaced electrodes supplied with alternating current are partly immersed in the water and by heating up generate steam which is conducted through pipes and nozzles to the room. The current flowing between the electrodes and the energy consumed is constantly monitored. The values obtained are used to control the inflow of water or the outlet of water from the tank so that a preset constant amount of water is converted into steam. The system automatically compensates for scaling up of the electrodes or for variable water conductivity.

Title: Complementary field effect transistor - produced by widening windows for one to windows for other channel type
Inventor: SPLITTGERBER HEINZ DIPL PHYS D
IPC: H01L21/8238
Filed: 1974-11-11
Abstract: Complementary field-effect transistors (FETS) are produced by applying an insulating layer on the surface of the n-type semiconductor substrate exposed in the first windows. To produce-channel FETs some windows are widened and a doped silicon layer is deposited. This doped silicon layer is used to produce both the substrate regions for the n-channel FETs by a heat treatment and a conductor track plane for p-channel FETs. This reduces the number of necessary operational steps to a minimum. It creates an additional conductor track plane which is an advantage for integrated circuits.
