Title: Mortar composite cladding for wall surfaces - has regular spaces in grid weave for mortar to form protruding pattern
Inventor: LUX HERBERT
IPC: E04F15/02
Filed: 1975-12-20
Abstract: The process is for cladding floor, wall, ceiling or partition wall surfaces with square, rectangular or other panels, which may be made of natural or artificial stone or concrete, plastic, glass or ceramic materials. A stable but elastic grid weave of glass, plastic, cellulose, or stone thread is used. Open areas are left in this, in a set pattern, and by these the soft mortar, being pressed through, makes up a clear, plastically protruding closed joint configuration. The mortar strands making up the grip pattern may correspond to the normal joint gap breadth. The rib formation is made up from soft mortar, not yet set, offering no resistance to edge-less panel laying.

Title: Switching capacity testing of metal cased power switches - using case voltage supply of opposite polarity to test voltage to allow for open circuits
Inventor: HUBER HERWIG
IPC: G01R31/333
Filed: 1975-12-27
Abstract: A method of synethic testing of the switching capacity of metal encapsulated power switches is designed to take account of open circuit failures in the system of voltage leads between the voltage paths and the earthed casing when multiple contact switches are being tested. The metal casing of the switch is insulated from earth potential and connected to a voltage of opposite polarity to the test voltage via a resistor, an inductor, or a series or parallel combination of a resistor and an inductor. This ensures correct loading of the non-earthed side of the test specimen in the event of failures leading to open circuits.

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: C07D295/15
Filed: 1976-06-10
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.
Patent DE-2630775-A1 (DE)
Title: Peristaltic liquid pump for medical use - has recess in hose to provide minimum free area(BE070177)
Inventor: CALVET GERARD
IPC: F04B43/00
Filed: 1976-07-08
Abstract: The pump has a flexible hose (1) which is periodically compressed between rollers and released to vary the internal volume and thus propel liquid through it. A semi-circular recess (3) is cut longitudinally on the inside of the hose at one part of the cross section. Because of this at least the cross section of the recess is left open even when the rollers fully compress the hose. There is thus a minimum free area left through which air entrained in the liquid is free to flow back to an air vent and this area is maintained at all rates of pumping and delivery pressures. This provides the safety required of blood pumps used during certain surgical operations.

Title: Automatic speed control for tracked vehicles - uses optical method independent of central processing station and associated signal transmission cables
Inventor: MEIER HERMANN DIPL ING
IPC: B61L3/06
Filed: 1976-08-09
Abstract: A speed control system is for tracked vehicles in partic, electrically driven vehicles. It uses transmitters and receivers mounted on the vehicle and interacting with the control system. It is designed to operate without a central processing location and associated cables. The information determining the safe speed for each stretch of track is passively stored on that stretch. The transmitter is a light source so directed towards a reflecting strip along the back that its light beam is reflected to the receiver. Speed control is achieved by arranging different polarisation plane rotations for the various speeds in different track sections. The receiver converts the light into a control current proportional to the polarisation angle and hence speed.

Inventor: PUETZ GEORG ING GRAD
IPC: F02G5/00
Filed: 1977-03-02
Abstract: Dwelling houses and business premises combine to provide an economic energy supply. The energy source would be natural gas or heating oil feeding conventional internal combuston engines and boilers. The energy producing engines could run continuously or intermittently with energy storage. All waste heat would be diverted to the heating circuit. The engines would be run at the most economical load and any excess produced would be converted to heat and transferred to the heating system. The advantage claimed is that the public supply system would be stabilised.
