Title: Driving device for a windscreen wiper
Inventor: SEIFERT NORBERT
IPC: B60S1/34
Filed: 1983-09-29
Abstract: A driving arrangement for a windscreen wiper is specified, in which the driving spindle for the windscreen wiper is divided and that part of the windscreen wiper spindle which is connected to the wiper blade executes a lifting movement which overrides the swivelling movement and matches the curvature of the windscreen. As a result, the contact pressure of the wiper blades against the windscreen can be kept constant and, with the omittance of the contact-pressure springs and joints which are otherwise required, the inherent elasticity of the wiper arms themselves can be utilised for applying the contact pressure.

Patent DE-3341718-A1 (DE)
Title: Units through which fluid flows with pistons moving backwards and forwards in cylinders, such as pumps, motors, combustion engines or internal combustion engines
Inventor: EICKMANN KARL
IPC: F02B75/18
Filed: 1983-11-18
Abstract: Twin-piston engines and free-piston engines are investigated for their advantages and disadvantages. It is found that free-piston engines are difficult to control satisfactorily at high frequencies due to the necessity of braking the kinetic energies of the piston. In addition, excessively sudden pressure and power peaks occur next to troughs. New engines are therefore proposed, in which the stroke movement of the free piston is monitored and controlled. Furthermore, twin-piston engines are specified which are simple to control and inexpensive to produce and manage without the conventional valves or with simple valves. It is thus even possible to construct high-speed combustion engines which, while having a low weight, can output high power at the crank drive or in fluid flows. These new types of engine promise to deliver such high power at such a low weight that it no longer seems impossible that they will almost come to equal shaft gas turbines for use in aircraft as regards their power to weight ratio. The provisional theoretical basis for the calculation of such engines is provided in a mathematical analysis. <IMAGE>

Patent DE-3405268-A1 (DE)
Title: Device for the sterilisation of an endoscope
Inventor: WOLF HANS JOACHIM
IPC: A61B1/12
Filed: 1984-02-15
Abstract: A device for the sterilisation of an endoscope comprises a trough and a carrier insert for insertion in this trough. The trough and the carrier insert have a central, deep region and a higher region surrounding the latter, so that regions which lie on top of one another are only slightly spaced apart on insertion of the carrier insert in the trough. The observation part of the endoscope is placed into the central, deep region of the carrier insert, while the supply hose and the observation hose are guided annularly and in parallel with one another around this central region onto the second, higher region of the carrier insert and are completely covered by the liquid disinfectant. This device permits complete disinfection of an endoscope with a minimum requirement of liquid disinfectant and secure holding of the endoscope.
Patent DE-3406228-A1 (DE)
Title: Hydraulic system for an agricultural tractor
IPC: A01B63/10
Filed: 1984-02-21
Abstract: A hydraulic system for agricultural tractors, which is divided into a main circuit and a secondary circuit, is disclosed, each circuit to be supplied from its own hydraulic pump. The flow of hydraulic fluid required by a device in the secondary circuit, such as, for example, power-assisted steering, must be approximately constant, so that an excess flow of residual fluid conveyed by the hydraulic pump of the secondary circuit is branched off. This flow of residual fluid is, via a valve, either fed to the main circuit or conveyed directly back to a reservoir, the valve allowing the feed to the main circuit only when the units located there actually require the available quantity of residual fluid. This ensures a considerable reduction of the hydraulic power losses of the hydraulic system as a whole.

Title: Mid-stream urine collector
Inventor: CAWOOD CHARLES DAVID
IPC: A61B10/00
Filed: 1984-08-17
Abstract: There is described a sterile mid-stream urine collector which has an open-end, tubular body and a dish fitted therein. The dish has an open end provided with a covering which is at least partially made of a water-soluble material. On use of the apparatus the covering at the beginning deflects a urine stream which flows through the collector, and the covering dissolves within seconds in such a way that a following, uncontaminated part of the stream can enter the dish. A sample discharge passage extends away from the dish and is connected to a collecting tube arrangement or is designed such that it can be connected to the collecting tube arrangement which may have the form of an evacuated collecting tube having a piercable closure or which is formed by a syringe with a retractable piston.
Patent DE-3434552-A1 (DE)
Title: Process for forming a pn boundary layer
Inventor: ITOH HARUO
IPC: H01L21/223
Filed: 1984-09-20
Abstract: The invention relates to a process for forming a pn boundary layer by using an ion implantation process with low-resolution mass separation or without mass separation, and an annealing process. Into the semiconductor substrate, ions are implanted by means of ion implantation with low-resolution mass separation or without mass separation, which results in a high throughput, and the semiconductor substrate is then annealed to form an oxide film on the substrate surface and to diffuse the dopant in an oxidising atmosphere. In the case of a solar cell, a p-type silicon substrate is subjected to ion implantation without mass separation, using PH3 as the discharge gas. The ion implantation process is carried out with an energy of 25 keV and an overall ion dose of 5 . 10<15> cm<-2>. This is followed by annealing the substrate in humid oxygen at a temperature from approximately 700 to 1000 DEG C. The resulting solar cell has an off-load voltage of approximately 0.58 volt.
