Title: Device for generating superimposed electric oscillations
Inventor: DOMES RAINER
IPC: H04M1/50
Filed: 1981-03-25
Abstract: To generate the summation signal of two electric oscillations with different frequencies which are to be superimposed on one another, a sinusoidal value memory (SSP1, SSP2) with binary-coded output values which is activated on the input side by means of assigned address decoders (DEC1, DEC2) is allocated in each case to each of these oscillations. The memory inputs of the sinusoidal value memories (SSP1, SSP2) are activated cyclically by the address decoders. The frequencies of the sampling cycles are identical to the frequencies of the corresponding oscillations which are to be superimposed on one another and which are replicated at the inputs of the address decoders (DEC1, DEC2) by corresponding pulse strings. The summation signal is obtained from the sum of the output values of the sinusoidal value memories (SSP1, SSP2) which is derived in digital form by means of an adder (ADD) through subsequent digital-analog conversion in a digital-analog converter (DAW). <IMAGE>

Title: Device for the electrical starting of internal combustion engines
Inventor: WELSCH DIETER J
IPC: F02N11/12
Filed: 1981-06-22
Abstract: Low power internal combustion engines which serve as drive for lawn mowers, rotary cultivators or similar appliances are often reluctant to start. Causes of this are, for example, relatively long periods between use, inadequate maintenance, oiled-up spark plugs, reduced compression due to wear and/or sticking gasket rings etc. Since drives of this type generally do not have any electrical starter and are started manually, for example by means of a starter cord, the starting process can be difficult and protracted where the above-mentioned reasons apply. It is known that a suitable starting device for reliable starting is one which can also drive the internal combustion engine to be started at a sufficiently high speed for a longer period of time than in the case of a manual starting device. The basic concept of the invention is that a commonly available tool, with the aid of a special device, is alternatively used as electrical starting equipment. In this the torque of a conventional power drill is used to start the internal combustion engine, the torque being transmitted to the internal combustion engine by the device, fig.1 showing a possible application. <IMAGE>

Title: Suspendible grid ceiling, in particular strip-grid ceiling
IPC: E04B9/26
Filed: 1981-12-09
Abstract: The invention relates to a suspendible strip-grid ceiling having continuous strip-grid longitudinal profiles and, at the points of intersection, strip-grid transverse profiles butted against the strip-grid longitudinal profiles, and also having a suspension construction for the strip-grid profiles and optionally insertable ceiling panels. In order to realise an extremely simple construction in respect of manufacture and installation, the invention teaches that the strip-grid longitudinal profiles are constructed as flexible panels and the strip-grid transverse profiles are constructed as flexible panel portions, and that the suspension construction has supporting rails onto which the panels can be clamped from below transversely to the rail longitudinal direction directly and onto which the panel portions can be clamped from below in the rail longitudinal direction by means of clamping profiles, forming any desired grids. Like the panels and the panel portions, the clamping profiles can also be constructed as flexible panel portions and can be clamped into the panel portions forming the strip-grid transverse profiles and also clamped from below onto the supporting rails. <IMAGE>

Title: Centrifugally actuated coupling in the motor drive on office machines, especially typewriters
Inventor: MICHEL INGO DR ING
IPC: B41J29/38
Filed: 1982-03-11
Abstract: Centrifugally actuated coupling in the motor drive of an office machine, especially typewriter. The coupling allows the load-free starting of the electric motor and the automatic cut-in of the transmission when the motor has reached the speed necessary for the reliable functioning of the machine. The cost-effective coupling necessitating a low outlay is to safeguard the permanent operative connection between the motor and transmission above the cut-in speed in the event of abrupt loads and speed changes. This purpose is served by the arrangement and design of the centrifugal weight and the formation of the coupling tooth in conjunction with the design of the element to be driven. The coupling uses only a single sprung centrifugal weight having a coupling tooth which engages into one of a plurality of grooves made in the element to be driven. <IMAGE>

Title: Grinding device for gears with variable profile displacement
Inventor: LENZ SIEGHART DIPL ING
IPC: B23F1/02
Filed: 1982-08-13
Abstract: The invention relates to a device for grinding gears with profile displacement, variable with regard to the tooth width, on a tooth-flank grinding machine by varying the radial distance from the grinding body to the workpiece as a function of the stroke movement of the tool carrier. A device is to be provided for grinding precision gears with large variable profile displacement, with respect to the tooth width, on a tooth-flank grinding machine, which device requires no changes on the machine casing and entails no substantial losses in productivity. Inclination of the machine column is to be avoided and the horizontal mass forces are to be minimised. This is achieved by virtue of the fact that the grinding spindle head saddle is supported radially to the workpiece relative to the machine frame on the guide part of the tool carrier via a lever, a sliding piece and a bell-crank lever which are arranged so as to be connected in series from the tool carrier. However, the grinding spindle head saddle can also be supported radially on the guide part via a lever, a sliding piece movable at right angles to the stroke direction and a connecting rod which can be adjusted in length. <IMAGE>

Title: Device for removing pollutants from the hot gas fed to an engine
Inventor: EICKMANN KARL
IPC: F02G3/02
Filed: 1982-10-13
Abstract: The invention perfects the structure or the combustion system of an engine. Thus, the working cylinders are flushed by fresh air when the power stroke is complete, and this fresh air is precompressed in the working cylinders during the inward stroke of the pistons. High compression is then effected in the main compressor. The throughflow and onward transfer of the gases and the fresh air is brought about by appropriately designed valves, which are preferably swivelling or swing valves. A plurality of fuel tapes positioned one above the other at different locations to ensure completeness of combustion. Ash and foreign matter is collected by rotation and compressed in chambers under pressure to give solid masses which can be removed and stored better as small lumps. An automatic replacement device for the foreign matter collection container can be provided. Large piston strokes amounting to 40 per cent of the spacing of the relevant axes can be achieved. Pressure waves can be used to make combustion more complete or more intense. Water can be preheated or vaporised in the exhaust gas in the exhaust or in chambers of the system which are to be cooled, in order to inject steam or preheated water into the hot gases, cooling the hot gases, with the result that the temperatures of the system can be controlled better, mechanically, for high pressure drops ...
