Title: Flexible corrugated material - corrugations in sheet or tube material allow flexibility in several axes
Inventor: CIESLIK JOHANN
IPC: F16L11/118
Filed: 1973-11-07
Abstract: A corrugated material is provided in the form of a tube which has corrugated walls with the corrugations lying in planes transverse to the axis of the tube. The corrugations are of truncated 'V' section and have the particular advantage that gas flowing throught the tube set up a toroidal circulation in each of the corrugations which reduces frictional flow losses. The shape of the corrugations is optional and the material may be supplied in tube or sheet form, or with two sheets which sandwich between them acoustic insulation to be flexed in several directions and thus avoids the necessity for bending machines.

Title: Battery discharge indicating circuit - compares terminal voltage at differing rates of discharge under two load conditions
Inventor: PECHER HANS DIPL ING
IPC: G01R31/36
Filed: 1975-03-18
Abstract: The circuit monitors the effect on battery terminal voltage at the differing rates of discharge under two load conditions. When the difference reaches a predetermined high magnitude an alarm or indication is switched in. The terminal voltage when receiving may be stored in a capacitor and then compared, via suitable amplifiers and gates, with the value obtained under one condition. The latter may be applied via a monostable vibrator for a sufficiently long period to enable comparison and allow the subsequent switching of a flip-flop, if the set difference magnitude is exceeded. The alarm or indicator is under the control of the flip-flop, and switching back to the other condition resets the voltage on the capacitor.

Title: Crank shaft oil-ways formed, curved, by electrolytic machining - have low resistance to flow and cause less contamination
Inventor: SCHMEISS CHRISTIAN
IPC: F16C3/14
Filed: 1975-05-16
Abstract: Oil ways (8) are formed between the main bearings (4) and crank pins (3) of a crankshaft, in the form of two intersecting curves, thus providing a flow path for the lubricating fluid with characteristics far superior to those paths formed by straight drilling or boring from different angles. Electrodes (9), curved to the shape of the holes to be formed can be used with electrolytic machining methods to form several oil ways in one operation, 'S' shaped paths being formed by two 'C' shaped electrodes entering at different points on the crank shaft and rotating in opposite directions until they meet. The decrease in contamination caused by this type of machining and the possibility of using suitably formed electrodes to shape the entry and exit areas of the oil ways are further advantages for the process.

Title: Air cushioned surface skimming craft - has air curtain directed downward from ducts and nozzles in stub wings
Inventor: WITTMANN MANFRED DR ING
IPC: B60V1/22
Filed: 1975-11-27
Abstract: The surface skimmer has downwards angled wings (1) to trap a cushion of air between it and the ground, to support the craft. The wings are fitted with air ducts (25, 26) powered by a compressor (24) and providing an air curtain via jets (22) at the edges of the wings. The air curtain contains the air cushion and enables the craft to ride at a greater spacing from the ground. The jets are angled slightly inwards so that the cushion effect is enhanced with the jets nearer the ground. This prevents the wing tips from touching the ground. The greater operational height enables the craft to bank for turning. It dispenses with heavy skirts and also enables the craft to negotiate heavy waves.
