Title: End connection for synthetic cable - has sleeve with tapering bore clamping ring through which threads turn over
Inventor: WALDMANN KARL
IPC: D07B9/00
Filed: 1977-12-15
Abstract: A cable or rope of threads or fibres, esp. a synthetic cable in which the threads run parallel to each other, has an end connection formed by a sleeve in which the threads running axially are clamped by means of a fastening detail. This is a ring through which the threads are passed, whilst their free ends are turned back over the outer surface of the ring. The ring has its opening coaxial with the bore of the sleeve and it is clamped by the bore of the sleeve which tapers inwards. Supersedes an expensive anchorage and sealing system, which, whilst being acceptable for heavy cables is disproportionately costly for lighter products. The new end connection is fully capable of standing up to all requirements, as regards loading to the maximal capacity of the cable, but is cheap. Where a constriction is used, a painted line shows up any deformation due to overloading.

Title: Tablets produced from chewing gum granulate - obtained by cooling chewing gum until it becomes brittle
Inventor: NORDSTROEM RABBE DR
IPC: A61K9/16
Filed: 1978-02-25
Abstract: New tablets are produced from a chewing gum granulate. Tablets based n chewing gum granulates can be produced using conventional tabletting equipment. The chewing gum granulate can be used to achieve prolonged or delayed release of medicament. Furthermore, a sweet chewing gum core can be surrounded with a mantle contg. a bitter active ingredient; in this case, the initial bitter flavour becomes overlaid with the sweetness of the chewing gum, which is more acceptable than the usual case of an initially sweet flavour accompanied by a bitter aftertaste. The chewing gum granulate may contain the active ingredient, or the chewing gum granulate may be compressed together with a conventional tabletting granulate contg. the active ingredient. In an alternative formulation, the tablet may be in several layers, some of which may consist of conventional tabletting granulates.
Patent DE-2809194-A1 (DE)
Title: Gas pressure regulator with pilot control - uses small stable control diaphragm with input pressure on both sides
Inventor: GOTTFRIED JOSEF ING GRAD
IPC: G05D16/06
Filed: 1978-03-03
Abstract: The pressure regulator comprises a pilot diaphragm (5) and main control diaphragm (2) located in the same housing. The pilot diaphragm compares the output pressure set by the spring (29) with the actual pressure in the output nozzle (14). Deviations are converted to control commands for the main diaphragm which operates the regulator valve (22). Since the main control diaphragm is affected by the input pressure on both its sides, it has a high control stability and can be relatively small compared with the pilot diaphragm which determines the control accuracy. This arrangement provides rapid control action due to the small size of the control diaphragm, and the control valve (6) can be easily taken out of service if it is required to disable the regulating action.

Title: Printed circuit board mfr. - from prepregs coating metal carrier with plastic coated through holes
Inventor: BURGER RAINER
IPC: H05K1/05
Filed: 1978-03-15
Abstract: Printed circuit boards are produced by coating a metal carrier sheet on both sides with prepregs, applying the conductor racks and completing the through holes. The holes are enlarged by etching in the metal carrier and the space is filled by an insulating plastics layer of constant thickness. A metal carrier is cleaned and roughened before the layers of prepregs are applied. A pressed-on copper foil is etched to leave the conductor tracks under a mask. Etching also widens the bore of the holes which are produced and the wider section is filled up by an electrophoretically applied plastics layer. After removal of the mask, the connecting wires can be inserted from the bottom and soldered to the tracks. Coating is of uniform thickness, free from porosity of oxide layers which can be applied without major capital investment.
