Title: Fuel injection system with continuous fuel supply - has timing relay effecting run-down of fuel pump on ignition switch=off
Inventor: NOELLE KARL-OTTO
IPC: F02M37/08
Filed: 1980-08-16
Abstract: The combustion engine fuel injection system supplies continuous fuel admixture into suction manifold. It has an electric fuel pump with at least one differential pressure control valve and at least one injection valve. When the engine ignition has been switched off a timing relay (23) permits the fuel pump (15) to run down. In this manner the injection system pressure is maintained until the suction manifold vacuum has ceased. The time relay may be connected in parallel to the pump relay. The injection system disposes in a simple manner with problems connected with hot engine starting. This has been attained by supply of a certain basic volume of fuel to the suction manifold from the injection lines during the engine run down. This volume, however, is not sufficient for the engine idle run.

Patent DE-3111516-A1 (DE)
Title: Identity card with IC chip
Inventor: HOPPE JOACHIM
IPC: G06K19/077
Filed: 1981-03-24
Abstract: Identity card with IC chips for the processing of electrical signals. The IC chip and the conductor tracks and contact surfaces necessary for operating the chip are fastened on a separate carrier in such a way and are embedded in the identity card in such a way that the IC chip lies in a region of the card of maximum permissible thickness, whereas the contact surfaces are arranged outside this region. The placement of the IC chip in the raised card region (for example embossing region) allows thicker encapsulation of the chip with correspondingly improved protection against mechanical loads. On the other hand, the region of the carrier element with the contact surfaces is accommodated outside the raised card region, for example in the magnetic strip region. Since the carrier element can be made very thin in the region of the contact surfaces, its installation in the region of the magnetic strip of the card presents no problems in terms of production. Finally, this unproblematical installation of the thin contact-surface or conductor-track region arranged on the carrier element separately from the IC chip allows a very variable design of the contact surfaces in their dimensions and in their position on the identity card.

Patent DE-3128561-A1 (DE)
Title: Agricultural machine
Inventor: POHLMANN REINHARD
IPC: A01B59/043
Filed: 1981-07-18
Abstract: In an agricultural machine with a machine frame or machine structure having connections for coupling the machine to the three-point hydraulics of a tractor, for example in respect of fertiliser spreaders or silo-block cutters, the two lower-link connections of the machine frame are respectively attached to hydraulically actuable pivoting arms mounted on the machine, thereby making it possible to raise the machine beyond the pivoting range of the lower links of the three-point hydraulics without the use of a complicated lifting frame shifting the centre of gravity of the machine rearwards away from the tractor. The two pivoting arms can also be coupled rigidly to one another mechanically and be actuated by a common hydraulic piston/cylinder unit.

Title: Process for fabricating integrated MOS field effect transistors, employing a surface layer consisting of phosphosilicate glass on the intermediary oxide between polysilicon plane and metal conductor track plane
Inventor: WICHMANN BERNHARD DIPL PHYS
IPC: H01L21/3105
Filed: 1981-08-05
Abstract: The invention relates to a process for fabricating integrated MOS field effect transistors, which involves rounding the edges and borders on the surface steps or in the contact hole zones (6) of the intermediary oxide (3) between the polysilicon plane (2) and the metal conductor track plane with the aid of a surface layer (4) consisting of phosphosilicate glass by planarisation of this layer (4), before the metal conductor track plane is generated. In the process, planarisation of the layer (3) having a phosphorus content </= 6% by weight and the layer (4) is carried out at </= 900 DEG C in conjunction with densification of the intermediary oxide (3), the surface layer (4) is removed without changing the surface topology, and only then is the photoresist technique (7) for opening the contact holes (6) carried out. The process is used in the fabrication of complementary MOS field effect transistor circuits (CMOS-FETs). <IMAGE>

Title: Electro-pneumatic hammer drill
Inventor: FUCHS MICHAEL ING GRAD
IPC: B23B45/16
Filed: 1981-09-12
Abstract: An electro-pneumatic hammer drill, which is equipped with a device for changing over from hammer drilling to rotary drilling and vice versa, which device, to produce the rotary-drilling operating state, enables the tool spindle to be displaced axially away from the pneumatic percussion mechanism and enables it to be locked in this displacement position and which, to produce the hammer-drilling operating state, permits axial displacement of the tool spindle against the restoring force of an energy accumulator within limits while neutralising the locked position eliminating an axial movement of the tool spindle, is to be improved to the effect that it works free of vibration in the rotary-drilling operating state and permits deadly accurate positioning of the tool. For this purpose, it is proposed that the drive of the percussion mechanism be switched off automatically during change-over to the rotary-drilling operating state and that, after changing back to the hammer-drilling operation, it be switched on by pressing the tool against the workpiece. <IMAGE>

Title: Process for purification of flue gas from SO2, HCl, HF and preferably NOx downstream of coal-fired or oil-fired power stations and refuse incineration plants or other fired plants
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/50
Filed: 1982-08-14
Abstract: In flue gas purification, SO2, HCl and HF are separated by a circulating washing fluid which contains calcium ions, consumed calcium ions being replaced by addition of lime, so that calcium sulphate is formed as the end product. The process is less suitable for separating nitrogen oxides likewise contained in the flue gas. For this purpose, the gas is passed, after the desulphurisation, through a droplet separation device, to the first stage of which is supplied an oxidising agent, for example sodium hypochlorite solution, while an alkaline washing water, for example weak ammonia water, is supplied to a second stage. Both liquids are trapped together and conducted into a circulation tank and from there into a stripper column, in which the chemically bound ammonia is released, so that the liquid can be reused as washing water.

Title: Windsurfing board
IPC: B63B35/79
Filed: 1982-09-15
Abstract: A windsurfing board with fastening devices for a universal-joint mast and drop centreboard is designed according to the invention as a twin-hull board with an intermediate piece forming the standing surface. This results in greater stability, especially for beginners, improved usability in extreme wind and wave conditions as well as suitability, for example, as a bathing island or for transporting several persons. This construction is advantageously configured in such a way that it can be divided into the two hulls and the intermediate piece in order to improve transportability. In this arrangement, the two supporting hulls are advantageously designed as longitudinal halves of a board of conventional construction so that a faster board which is more interesting to sail and is of commercially available construction can also be assembled with these parts.
