Patent DE-2910353-A1 (DE)
Title: Infusion syringe drive - with spur gear stages chosen by drag keys inside hollow shafts
Inventor: WEBER FRIEDRICH
IPC: A61M5/145
Filed: 1979-03-16
Abstract: An infusion appliance for electro-mechanical operation of hypodermic syringes is fitted with synchronous electric motor and a multi-gear box, e.g. consisting of constantly meshing spur gears of ten different ratios. The output gears run on a hollow output shaft and the chosen ratio is engaged by pulling a drag key along the shaft. A similar second stage, consisting e.g. of three spur gears, is again engaged by moving a drag key inside a hollow shaft. The last gear ratio finally actuates a feed screw mechanism for the syringe plunger. This simple device enables a precisely reproducible amt. in many small steps to be injected.

Abstract: The initiator has a rectangular housing designed for firm fastening and is connectable to an electric line. It contains an electric measuring head with an oscillator, an evaluator portion and a cable aperture. The housing is divided into a fixed lower part with the cable aperture, and a releasable upper part containing the measuring head and the evaluator part. In the region of the housing long centre axis the lower part has threaded bores, while the upper part has through bores, aligned with those in the lower part. All the bores are separate from, and independent of fastening element for securing the housing on a base. A set of three bores are provided, one lies in the region of the cable aperture facing front side, the other two being near the front side facing the measuring head. The through bores may contain screws in non-releasable arrangement.

Title: Winding device with moving arm to form windings - fits in chambers for making field coils and coil sets for electric motor
IPC: H02K15/04
Filed: 1979-04-17
Abstract: The device has an arm via which wire passes into the consecutive chambers. A cog cooperates with a pawl rotatable about the same axis and has a shutter partially covering its teeth. The pawl is driven by an electromotor and pivots through 180 deg. in order to cause the arm to jump from one chamber to the next. At the same time the cog rotates through a given angle, dependent on the position of the shutter, and the movement of the pawl is transferred to the arm. A slide sits on the arm and is moved by an endless chain. The chain wheel is preceeded by a gear that transfers the pivoting motion of the cog in both directions to the chain wheel.

Title: Water meter outlet and stop valve screw connection - has collar on stop ledge, and valve cone shaft near disc seal
Inventor: SEPPELFRICKE OTTO DIPL ING
IPC: F16K27/00
Filed: 1979-05-26
Abstract: The pipe socket end (2), protruding into the box nut (4), for which it has a stop ledge (19), is also fitted with an inward valve-seating collar (6) in the cross-sectional plane of the ledge. It is used in a screw coupling connecting a water meter outlet to a stop valve. The screw coupling pipe (1) contains a spring-pressed valve cone (8), with the shaft turned away from the collar. Its thread end (3) is a removable cap (13), not wider than the box nut hole (5). A hard disc seal (14) is clamped inside, and a guide cross-piece (11) for the valve cone shaft is located between this seal and an inside ledge (12) on the pipe. This needs neither a special valve with integrated return flow stop, nor separate return flow stop.

Title: Closed TV circuit - for observation of performance of lorry mounted concrete mixers
Inventor: SCHREYER WILFRIED ING GRAD
IPC: B28C5/42
Filed: 1979-06-20
Abstract: A large-capacity mixer, esp. a lorry-mounted concrete mixer, is equipped with a closed TV circuit which allows an inspection of the progress, uniformity and consistency of the mixt., and also any wear on exposed surfaces. A powerful lamp and a TV camera are mounted under a flap with a power cylinder drive at the charging end of the mixer and their cone of vision is directed axially in the vessel, when the flap is open. The TV screen is arranged at a suitable spot, such as the driver's cab. In view of the poor accessibility for inspection of such mixers, the new method is especially important for mixes which are to be transported by pumps.

Title: Monitoring circuit for carrier frequency regulating circuit - has amplifier with logarithmic characteristic, series connected to pilot signal filter, amplifier and rectifier
Inventor: BLOEMKER UWE
IPC: H04B3/10
Filed: 1979-08-09
Abstract: The monitoring circuit is intended for pilot-controlled regulators of high frequency amplifiers. It is used for such control circuits in case of level surges. An amplifier with a logarithmic characteristic is series connected behind a device for filtering, amplifying and rectifying of the pilot signal, for linearising the pilot direct voltage. The series-connected amplifier is used for attaining a constant steepness of the voltage characteristic over the entire control range. Pref. the setting voltage is so matched to the linearised pilot voltage, using a function generator, that the alarm warning and blocking of the control devices takes place always when identical input levels occur. The monitoring circuit thus provides constant response value also in case of large level deviation.

Patent DE-3001318-A1 (DE)
Title: Coal conversion into hydrocarbon(s) - in unit with compression chamber, hydrogenation chamber and hot separator
Inventor: KOCH KLAUS DIPL PHYS
IPC: C10G1/06
Filed: 1980-01-16
Abstract: Coal is coverted by hydrogen into hydrocarbons by feeding dry coal particles in powder or granules continuously through sealed metering devices into a chamber where they are compressed and transformed by frictional heat into a plastic state. The plastified coal is kept in intensive motion with uniformly distributed and dispersed hydrogen to effect the hydrogenation in a treatment chamber followed by a hydrogenateion chamber. The final state is a hot separator for plastic and gaseous products of hydrogenation. This combines the process stages of compression, heating, plasticising and hydrogenation in one common unit at very great savings in cost. The process requires no expensive paste producing oil. The compact design requires very little space.

Title: Serum insulin normalising sulphonyl-urea deriv. - N-chloro-methoxy-benzamido-ethyl-benzene:sulphonyl-N'-methyl-urea
Inventor: ENZMANN FRANZ DIPL CHEM DR
IPC: A61K31/64
Filed: 1980-03-22
Abstract: Use of N-/4-/2-(5-chloro-2-methoxybenzamido) ethyl/ benzenesulphonyl/ -N'-methylurea (I) and its physiologically tolerable salts of normalising the serum insulin level is new. (I) (a known hypoglycaemic agent - see DE2413514) lowers supranormal insulin serum levels. In addn., (I) potentiates the nutrition-induced increase in insulin level when the serum insulin level is subnormal or is at the normal basal level. (I) is accordingly suitable for the treatment of maturity onset diabetes, as well as for use in the treatment of overweight patients with hyperinsulinism.
Patent DE-3020520-A1 (DE)
Title: Amusement game with transparent container - involves air bladder changing liq. pressure to change buoyancy of floating objects
Inventor: SEEFLUTH UWE C
IPC: A63H23/08
Filed: 1980-05-30
Abstract: The amusement game consists of a liq. container which is at least partially transparent, in which a floating element is located movable by changing the degree of buoyancy. The buoyancy can be adjusted by compression of an air bladder positioned inside a hollow chamber of the floating element housing through a pressure generator in the liquid container. The liq. expelled out of the housing of the floating element during an extension of the air bladder or of the air filled space inside the floating element produces an especially horizontally directed acceleration created by the recoil force.

Title: Bulk material treatment appts. - with enclosed casing having air circulation through perforated conveyor belts and slotted gas nozzles
Inventor: KAMMER GUENTHER
IPC: F26B17/08
Filed: 1980-11-17
Abstract: A device for the treatment of bulk materials, specially material such as sugar beet shreds which are to be converted to animal feeding stuff, has an enclosed casing with air inlet slots through which fans draw in air. Several conveyors with perforated belts are so arranged that the air must pass through the perforations. Baking arms above the belts keep the material in a loose state. In addition, slotted gas nozzles are fitted below each belt for a compressor to blow gases through the material. This ensures a uniform treatment and saves energy for the subsequent drying stage by a predrying from 75 to 6% moisture content.
