Patent DE-2604411-A1 (DE)
Title: Integrated two transistor component - has electrodes length selected to provide different transistor current strength
Inventor: GOERTH JOACHIM DIPL ING
IPC: H01L29/423
Filed: 1976-02-05
Abstract: The semiconductor component has several transistors formed by integrated circuit technique in a semiconductor chip. An emitter zone bounds each substrate surface and is surrounded by a base zone with a connecting electrode, extended parallel to the pn-junction between the emitter and base. The transistors are operated with identical base-emitter voltages, but conduct different currents. With identical size of the emitter zones (2a, 2b) of the individual transistors (T1, T2), the length of the base connecting electrodes (5a, 5b) is so chosen, as to provide different currents through the transistors. Preferably the electrode length equals the emitter zones width.

Title: Diaphragms for electrolytic cells - comprising (asbestos) fibre suspension deposited on cathode screen with fluorocarbon binder
Inventor: PATIL ARVIND SHANKAR
IPC: C25B13/04
Filed: 1976-03-01
Abstract: Diaphragms for electrolytic cells are made by depositing a fibre suspension on the cathode screen and bonding the fibres together by contacting them with a fluorocarbon binder.

Title: Rack mounted massive busbar pair - has forward and return conductors separated by thin insulation forming HF strip line for HF propagating voltages
Inventor: MENZEL WILLI
IPC: H05K7/06

Title: Amino-substd. alkyl nitriles prodn. - from amines, carbonyl cpds. and hydrogen cyanide, useful e.g. as pharmaceutical and agrochemical intermediates
Inventor: DISTLER HARRY DR
IPC: C07C255/24
Filed: 1976-05-15
Abstract: Prepn. of glycine nitriles of formula R3R4N.CR5R6.CN (I) comprises reacting amnes R3R4NH (III) with carbonyl cpds R5COR6 (IV) and HCN in presence of water for 0.1-4 hrs. at 0-80 degrees C. The condn. of HCN never exceeds 0.9 wt. % of the reaction mixt. In the formulae, R3-6 are aromatic, cycloaliphatic or araliphatic gps.; R3 and R4 may together complete a heterocycle; R4-6 may also be H, and R5 and R6 may also be aliphatic, and when R5 and/or R6 is aliphatic aromatic, cycloaliphatic or araliphatic, then R3 and R4 can also be aliphatic. Pref. the products where R3-6 are aromatic gps., R5 and R6 may also be H, aliphatic, cycloaliphatic or araliphatic, and R4 may be H, are subsequently treated with an acid at pH 1-7. (I) are stabilisers; intermediates for dyes (e.g. indigo) fungicides, bactericides, textile auxiliaries and antigelling agents; and by saponification give glycine salts useful as selective adsorbents for CO2, SO2 and H2S, and by hydrogenation give assymetric diamines useful for making pharmaceuticals and plant protection agents. Cf. the process of DT 1543342. This method is simpler and more economic giving better yields of purer products. Water pollution and formation of resinous by-products are minimised, and subsequent acid treatment obviates expensive purification steps and avoids losses of solvent.

Title: Coupling and splicing point adjustment for light waveguides - ensures accurate connection between incoming and outgoing waveguides by reducing intensity of scattering
Inventor: WITTMANN JULIUS DIPL ING
IPC: G02B6/38
Filed: 1976-06-15
Abstract: The light wave guide adjustment is for coupling and splicing points and ensures accurate connection between incoming and outgoing light wave guides. The coupling provides a detachable connection bub splicing does not. If the ends of the light wave guides are not exactly adjusted to each other at the coupling points, losses of light will occur at the coupling points. Light is fed into the incoming light wave guide (1). The intensity of scattering light produced at the coupling point (K) is determined at the coupling point. The light wave guides (1, 2) are adjusted such that the intensity of the scattering light is kept to a min.

Title: Draw-leaf table with stable extension plate - has keyed engagement between extended leaf and table
IPC: A47B1/05
Filed: 1976-11-12
Abstract: The draw-leaf table is provided with a least one pull-out extension leaf (4) which in the extended position is in keyed engagement with the table top (1) which is rigidly attached to the top rail (2, 3). This positive engagement can be achieved by providing one of the plates (1, 4) with a projection (10) which engages in a recess (12) provided in the other plate. This fixed positioning of the extension plate allows the table to be moved even when the plate is extended and also prevents the plate from being extended too far. Furthermore, the extension plate can be moved back beneath the table top (1) without the latter having to be raised. The longitudinal guide for the extension plate (4) can be a bar (6) attached to the underneath of the plate for movement in a recess in the top rail of the table and can be vertically adjusted relative to the table top (1).

Title: Casting plastics toothed transmission belt with spiral reinforcements - in mould comprising annular outer component, and core with axial indentations
Inventor: KLOSOWSKI MANFRED
IPC: B29D29/00
Filed: 1976-12-08
Abstract: Mould for mfr. of toothed transmission belts from casting resins, with embedded, longitudinal, helical, filamentous, reinforcements, has an annular outer part and a mould core with axial depressions corresponding to the teeth of the transmission belt. The outer part is provided with (approx.) circumferential depressions in its inner mantle surface.

At the same time, the depressions in the mould mantle surface facilitate removal of the casting from the mould once the resin has set.
Patent DE-2705263-A1 (DE)
Inventor: TRESCH ERWIN
IPC: G08B17/10
Filed: 1977-02-09
Abstract: The smoke detector has a radiation source with a radiation characteristic in the shape of a tapered ring and a radiation sensor which is arranged in the axis of the tapered ring and receives the radiation dispersed onto smoke particles in the radiation area in the shape of a tapered ring, and evaluates the said radiation in order to output signals. In order to achieve a radiation characteristic in the shape of a tapered ring, a radiation-emitting element (6) is arranged inside a conic-section rotation face (3), the axis of the conic section being arranged at an angle with respect to the axis of rotation or axis of the cone or, if the generatrix is a conical surface, its centre point is arranged outside the axis of rotation. The radiation which is emitted by the radiation-emitting element (6) laterally onto the rotation surface (3) is concentrated into the desired zone (K) which is in the shape of a tapered ring in conjunction with a surface (4) which surrounds the axis in an annular shape and is also constructed as a conic-section rotation surface with an oblique axis. Additionally, the radiation which is output forwards by the radiation-emitting element (6) in the direction of the axis of the cone is interrupted by a further surface (5) which is also constructed as a conic-section rotation face which has an oblique axis or is eccentric, and is concentrated into the same zone (K), in the shape of a tapered ring, as the radiation passing via the reflector (3). The utilisation of the radiation and the efficiency of the smoke detector are thus improved. The smoke detector is provided in particular for warning of fires. <IMAGE>

Title: Alternating alkaline effluent and flue gas neutraliser and cleanser - has two zone column and alkalinity monitor regulating gas throughput
Inventor: ANTIPOVIC PETR DIPL ING
IPC: B01D53/48
Filed: 1977-03-03
Abstract: The plant consists of a contact cooler, an absorber or scrubber and a pH regulator; the contract cooler being formed by a vertical vessel with a butterfly valve regulating the feed of the flue gases. At its upper end there is a sprinkling arrangement for washing the hot gases with effluent which is drained away at the bottom. A pH regulator monitoring the drain fluid controls the servo for a valve in the gas feed line. The installation takes up little room and is controlled automatically. The content of organic impurities in the liq. is reduced at the same time as the alkalinity is neutralised, and sulphur and dust are removed from the flue gases. Method is cheaper and less dangerous to health than using hydrochloric acid.
