Patent DE-4340449-A1 (DE)
Inventor: ZUNDEL WERNER
IPC: B29C51/46
Filed: 1993-11-27
Abstract: By the invention it is intended to bring about a rapid build-up of the mould pressure for the compressed-air forming of an article made out of a thermoplastic sheet, without exceeding the predetermined value. This is achieved by installing a proportional valve, which feeds the forming air initially with the full cross-section and then, dependent on the forming pressure produced, constricts this cross-section shortly before reaching the forming pressure and closes it when the forming pressure is reached. The invention is represented characteristically by Figure 1. <IMAGE>

Title: Device for removing wild weed growth on facilities, such as paths, squares and parks
Inventor: WEISS GUENTHER
IPC: A01B19/06
Filed: 1994-03-11
Abstract: The invention relates to a device for removing wild weed growth on paths, squares, parks and similar facilities, which in particular have a covering of pebbles, sand, broken stones or the like. The device has a device carrier with at least one movable component, on which at least one tool is mounted, which is to be brought into contact with the ground. In order to achieve a great cleaning effect for the device with only minimal damage to the ground, it is envisaged that the tool has a shoe-like base part which, on its front edge facing in the direction of travel and on its side edges, has cutters, with which it penetrates the ground at least partly, and that the tool performs an oscillation movement which runs essentially transversely to the direction of travel. At the same time, the tool can be inclined downwards in the direction of travel. The base part is preferably of essentially plate-shaped design and the cutters are formed by downwardly bent edge regions of the base part.
Patent DE-4409677-A1 (DE)
Title: Motorised sledge
IPC: A63C5/08
Filed: 1994-03-17
Abstract: Motorised sledges in use have the disadvantage that the person to be conveyed is situated on this sledge. As a result, the sledges are of compact construction and limits are therefore set on their off-road mobility. The novel, universal sledge is independent of the person to be conveyed since this person propels himself on skis and is pushed by the sledge. This system is very mobile off-road and can be used as equipment for sports, rescue or for transportation in difficult, snow-covered terrain. By removing the snow chains and the corresponding wheels and by fitting two floating shoes and a propeller this sledge can be used in the summer by a water skier.
Patent DE-4412805-A1 (DE)
Title: Shoulder belt for the safety-belt system for pregnant women
Inventor: WIPPER ANDREAS DIPL ING
IPC: B60R22/02
Filed: 1994-04-14
Abstract: In the event of road accidents involving vehicles, pregnant women are very much at risk with or without the conventional safety belt of a motor vehicle. In the event of accidents, the belt running over the stomach and the pelvis results, in most cases, in pregnancy-related injuries. The invention solves the problem since the shoulder belt for the safety-belt system for pregnant women ensures a belt-free zone for the stomach area (child-bearing area) and the chest of the pregnant woman. The shoulder belt (1) runs from the belt retractor (2), between head support (6) and back rest (5) or seat shell (5), over the right and left shoulders of the pregnant woman, and beneath the right and left arms through to the belt buckles (4). <IMAGE>

Title: Measuring surface elasticity of liq.
Inventor: STEWEN ALWIN
IPC: G01N3/00
Filed: 1994-05-05
Abstract: A gas bubble (8) is produced in the liq. (F) concerned and, from the results of measuring the relative change in the surface of the bubble and its internal pressure, the surface elasticity of the liq. is derived. A pressure unit (P) produces the gas bubble via a capillary tube (5).The bubble can be radiated by parallel laser light for reflection from the surface area. The change in the latter can then be calculated from the change of light shadow cast by the bubble. This surface change can be measured optically by a laser source (1) and a photocell (12) sensitive to laser light. The evaluation unit (A) pref. consists of a voltameter measuring the photo-voltage produced by the cell (12), a pressure pick-up for the internal pressure of the bubble and a data processor to calculate and display the surface elasticity.

Title: Boiler burner control and regulation
Inventor: EISFELD FRITZ PROF DR ING
IPC: F23D14/60
Filed: 1994-08-08
Abstract: The start-up burner for a boiler is fuelled via electronic-mechanical control. This feed is choked off after a pre-set time and simultaneous release and increase of fuel feed up to normal operation level. The start-up burner is then cut out. Either gaseous or liquid fuels can be used and the switch to start-up takes place directly the burner has been cut out. The mix ratio of the fuel is monitored by mechanical-electronic control of air and fuel volumes and the burner is cut out should the mix deviate from the permitted band range. Mix ratio is typically controlled using a sensor which interrogates the position of a blower air flap for comparing with the fuel pressure upstream of the vaporiser, cutting the burner out if mix deviates, followed by immediate switching to start-up etc.
