Patent DE-2758804-A1 (DE)
Title: Electric cable twisting unit - has a strand guide and feed mechanism which handles a larger number of strands
Inventor: VOGELSBERG DIETER DIPL ING
IPC: H01B13/02
Filed: 1977-12-29
Abstract: The equipment to twist electric cable material, with layers of left and right twists, has a tubular rotating body as the store unit. For each strand there is a guide fixed to the twisting disc running radially to the store. Thsi brings out the strands from the store. A non-rotating guide outside the twisting unit brings all the twisting strands in parallel to the store, radially to the store, as it does not rotate round the twisting axis. The feed and/or the drawing out guides slide forwards and back along the lines of the twisting unit. The system allows the use of a higher number of twisting strands, and the gap between the twisting direction change-over points gives at least more beaten lengths.

Title: Quantitative measurements of traces of harmful substances - using inert gas to expel substances from soln. to adsorption device
Inventor: BURGER KLAUS DR
IPC: G01N30/91
Filed: 1978-01-05
Abstract: Quantitative measurement of very small traces of cpds. (I) having a vapour pressure at 200 degrees C of >=1 mbar, in solns. is effected by expelling (I) from the soln. by an inert gas stream and then passing this stream through an adsorption device, esp. a packed column or thin-layer chromatography plate, where (I) are pptd. Used partic. for measuring very small quantities, of the order of parts per billion, of carbinogens, mutagens, teratogens and other harmful substances. Typical solvents used are pentane, hexane, dichloromethane, chloroform, acetone. Typical adsorption agents are silica gel, kiesel-guhr, polyamide, activated charcoal. Method ensures that only very small quantities of the accompanying substances present in the extract are precipitated in the adsorber. Thus the trace substances to be detected are concn. and sepd. from the accompanying substances in a single rapid stage.

Title: Appts. for producing resin-bonded fibre rods and tubes - with counter-rotating sets of filament reels feeding into tube with double resin application
Inventor: BERG A EINAR
IPC: B29C70/52
Filed: 1978-04-05
Abstract: Rods and tubes are produced from e.g. synthetic resin binder and e.g. fibre reinforcement. A number of first discs rotate in opposite directions, each bearing several reels of fibre material, these reels have control guides and brakes, the fibres are drawn through an orifice, a bath of binder lies between guides and the orifice whose inner conical part has a bell-shaped interior held in a cylinder. When the discs rotate, the fibres pass against the wall of the bell shape so as to form a dense mat after passing through the orifice; above that orifice the binder flows also through a ring gap in a valve to coat the outside of the mat; a number of other discs, also with fibre supply reels and guides, rotate in opposite directions and their guides systems are set close together to apply additional fibres round the outside of the mat. The fibres criss-cross to produce high impact strength, the outer and inner fibre layers have different winding angles, one orifice can produce cylinders or cones, the winding angle and/or fibre content can be altered as required.

Title: Double glazing panes - with at least one pane curved in centre and with plane peripheral strips
Inventor: SAWATZKI ROLF
IPC: C03C27/12
Filed: 1978-07-13
Abstract: A double glazing window has >=1 panes with a convex curvature to the outside. The edges of the curved pane are, however, plane strips for the width of the frame, i.e. a width of 10-15 mm. Pref. a layer of butyl rubber seals the joint between the side flanges of the frame and the panes; the channel between the edges f the panes and the outside web of the frame is filled out with thiokol. Bull's eye types of glass windows can thus be produced in double glazing design with the same quality of seal as plane windows.

Title: Locking hook for two-hinged sections - is guided by cylinder rotation to move from release to intermediate position overlapping pin which secures locking position
Inventor: REIBER HEINZ-JOACHIM
IPC: E05B65/08
Filed: 1978-07-31
Abstract: The locking hook operates in conjunction with a cylinder lock. The locking hook rotates into locking position for holding together two hinged parts. The hook closes both parts without a gap and ensures sealed connection. The seal fitted within the gap is deformed without any intervention from outside. The locking hook (15) is guided on rotating of the locking cylinder (7) so that this hook moves from a releasing position intermediate position in which it overlaps the locking pin (3). On further rotation the hook carries the locking pin along in straight line and ensures tight locking position. The locking hook (15) has at its locking cylinder end a circular hole (16) to accommodate a guiding washer.

Title: X=Ray intensifying screen contg. transparent microspheres - embedded in surface to prevent adhesion to films
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: G21K4/00
Filed: 1978-08-16
Abstract: An X-ray intensifying screen with a rough surface has small transparent, smooth balls of 80-120 mu dia. and high abrasion strength embedded in its surface and projecting above it by 15-50 (20) mu; the quantity of balls is 10-50(15-20)cm-2. Pref material for the balls is a polyamide possessing low friction and high wear resistance. Where the screen consists of a backing layer, a reflecting layer, a fluorescent layer and an antistatic protective coating contg. a hydrophilic pigment, (esp. frosting (matting) silica, the small spheres penetrate through the protective layer. This arrangement of small spheres in the screen surface enables it to be brought into contact with and subsequently removed from X-ray films without sticking to the films. The process can be repeated many times without sticking.

Title: Delay reduction for signal trains triggered by pushbuttons - uses repeated operation of same pushbutton for controlled delay of triggering after last individual triggering, using preset time stage
Inventor: ZAHNER PETER
IPC: B41J5/28
Filed: 1978-12-23
Abstract: The pushbutton circuit, for an electronic keyboard, is designed so that, when the same key (T) is operated repeatedly after the last individual triggering during the coarse of a given time stage, the triggering of the signal train is delayed by less than the duration of the original time stage. A second circuit (SK2) contains two memories (S1, S2) and a device (V) triggering the time delay when the key is operated, and a multiple pulse stage (MI). After the delay time has expired, a pulse appears in the pulse stage and, after the key has opened, the first memory is cleared, whilst the second memory remains set. The circuit is particularly intended for electromechanical typewriter key operation control, related to the individual key pressure values.

Title: Bread loaf dividing machine - has revolving cutter blade shaped like Archimedean spiral
Inventor: WARNKE KURT
IPC: B26D1/28
Filed: 1979-01-27
Abstract: A mechanical cutter to divide large round bread loaves into two is housed in a casing in which a horizontal shaft, driven by a gear motor and carrying a cutter blade, is accommodated in one section. The blade has the contour of an Archmedian spiral, with a radius of curvature increasing with increasing distance from the shaft. A partition with a slot for the blade divides off a second section with a door through which the bread loaf is introduced. A microswitch cuts off the motor when the door is open. A light barrier stops the knife blade away from the bread department after one revolution through 360 degrees. Such a machine has a higher capacity than a breadsaw.
