Patent DE-2207066-A1 (DE)
Title: Sinker - with upper edge raised above level of sinker - nose and closing edge
Inventor: KOHL KARL
IPC: D04B27/04
Filed: 1972-02-15
Abstract: Designed for use with spring beard needles in a warp knitting machine, esp. when working with bulky spun yarn, the upper edge of the sinker - (in the pressing zone) - is lifted to a plane above the sinker nose in a variety of symmetrical or assymetrical patterns or in a ridge. The purpose is to provide the pressing action on the needle, to press the already-formed stitch before the new stitch, without requiring the needle to be further lifted so that operating speeds can be increased.

Title: High yield pure divinyl sulphide prepn - from alkali metal sulphide and acetylene in aq. medium under mild conditions
Inventor: TROFIMOW BORIS ALEXANDROWITSCH
IPC: C08F28/04
Filed: 1972-12-11
Abstract: Divinyl sulphide (I) is prepd. by reacting an alkali metal sulphide with C2H2 in aq. or aq. organic medium at is not >170 degrees C followed by sepn of I. A 1-step reaction under mild conditions gives high (82 wt.%) yields of pure I from cheap and easily available raw materials. H2S, as industrial waste material, can be utilised. No waste prods. are produced. I is a monomer and intermediate, e.g. for oil additives, fuel antioxidants and stabilisers for synthetics. I is also a cross-linking agent.

Title: Travelling sheet metal oven - controlled by thickness-dependent potentiometer in series with resistance thermometer
Inventor: AHRENS DIETER
IPC: C21D9/56
Filed: 1973-05-23
Abstract: The temp. in a travelling heat treatment oven for metal sheets is measured by a resistance thermometer, and the thickness of the sheet metal entering the oven is measured by a feeler attached to a potentiometer. The thermometer is connected in series with the potentiometer and a controller for a servomotor which adjusts the heat output of a burner as a function of thickness and temperature. This saves any manual readjustment of the desired temp. when the sheet metal thickness fluctuates.

Title: Hydraulically assisted control rod insertion - for pressurised water reactor
Inventor: LANDGRAF HELMUT
IPC: G21C7/12
Filed: 1973-06-06
Abstract: Pressurised water reactor control rod actuation system in whic accelerated insertion of the rod is effected by a hydraulic loop linked in a parallel circuit off the main primary coolant circuit. The loop may be either manifolded or run in separate lines to each control rod actuator containment to minimise the consequences of loop failure. Pressure within the loop is maintained consistently above primary circuit pressure by a separate pump and thermal and particulate factors are accommodated by a cooler and filter. Isolating valves are provided for control and maintenance and a non-return valve locates in each line at each containment. The pressure drop through the containment is realised by the narrow annulus formed by the actuator and reactor stand-pipe and sleeve. The actuator is of the electro-mechanical type with a ratchet type actuator rod.
Patent DE-2330998-A1 (DE)
Title: Embrittlement temp. determination method - is for ferritic-pearlitic structural steels for general use and for shipbuilding
Inventor: BOEHM DIETER
IPC: G01N33/20
Filed: 1973-06-18
Abstract: The method uses nondestructive test. The embrittlement temperature (e.g. the NDT temperature) is determined for selected steel grades by the usual methods, and the ultrasonic attenuation is determined for the same batches of tested steel grades by the pulse echo method. A comparison curve is plotted for the two values. Further determination of the embrittlement temp. of finished components of specified steel grades is made only by the ultrasonic attenuation method. The NDT temp. is obtained from the comparison curve. The determined echo amplitude attenuation for the tested object is compared and evaluated with a screen image corresponding to a certain sheet metal thickness and brittle fracture temperature. The screen image for the echo pulse attenuation of the tested object is compared with an image for a reference speciment with known NDT temperature, and evaluated.

Title: Heating element support for glass-ceramic hot plate - uses leaf spring to press elements against top surface
Inventor: FISCHER KARL
IPC: H05B3/74
Filed: 1973-08-11
Abstract: The inverted view shows the rectangular frame which is divided by a longitudinal box section member in two rectangles, each of which is sub-divided into two unequal rectangles by similar box-section members. The heating elements are housed in dished pressings which have rectangular depressions around the edges of the undersurface. A channel section member is rivetted to a central support of the pressing and is supported at its other end by a leaf spring rivetted to the member with a tongue which engages with the depression. The method of support permits the use of the thinnest possible glass-ceramic hot-plate cover with better heat transmission.

Title: Dialling units in PBX's - consist of MOS subassemblies and evaluate key dialling signals
Inventor: REUSCH HARTMUT
IPC: H04Q3/62
Filed: 1973-12-20
Abstract: Key dialling signals converted into binary values are, on application of a first clock pulse, received by a first register through the dialling unit inputs. When the second clock pulse appears, they again arrive at the same dialling unit inputs, and after reception of the second key dialled digit they are again stored in the first register, connected by an adder to a shifting pulse source wich adds the register contents and retransmits them for further connection build-up to further switching elements. After the first clock pulse reception the first register input is blocked through an AND circuit, its output is unblocked, and a second register prepared for the converted signal reception.

Title: Ice cube making machine has low thermal inertia - obtained by using refrigerator tubes as walls of cube moulds
Inventor: JURETIC MIROSLAV
IPC: F25C1/04
Filed: 1974-03-01
Abstract: An ice cube making machine comprises a housing, containing a group of inveted, i.e. open-bottomed moulds, into which water is sprayed from below, and also an inclined grating down which the discharged ice cubes travel into a storage chamber. The tubes of the evaporator are flat in cross-section and themselves constitute the side walls and top walls of the ice cube moulds; inside these flat tubes, there are heating fluid pipes for warming the moulds when the ice cubes are to be discharged. The refrigerant flowing through the flat tubes passes around the external surfaces of these heating pipes. Pref. the flat tubes constituting the side walls of the cube moulds are trapezium-shaped in cross-section, so that the upper ends of the moulds are narrower than the lower ends; pref. also, the heating fluid pipes are in those flat tubes which form the side walls, optionally also in the tubes forming the top of the moulds. The freezing poing of the heating fluid is pref. below the lowest temp. encountered in operation. The thermal inertia of the system is low since heavy moulds are not used. Therefore the quantities of heat required are reduced.

Title: Bottle checking and sorting installation - uses oscillating circuit to sort out bottles containing cleaning liquid remainders before re-use
Inventor: RICHTER OLAF A
IPC: G01N33/00
