Patent DE-4202574-A1 (DE)
Title: Timer circuit using IC having counter, e.g. for domestic appliance - has two optical display elements alternately switched in dependence on counter state
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: G04G9/02
Filed: 1992-01-30
Abstract: The circuit includes an integrated circuit IC which contains a counter timer TIM with power-up reset POR, clock input TE, measurement logic input and output (ME, MA) and output OUT. The output bus TA and mark-space control TVS are processed by evaluation logic AS to produce drive signals to two LEDs (OAE1, OAE2). The drive current to the LEDs is controlled in mark-space ratio which is complementary. At the start of the timing interval measured by TIM, the mark-space ratio on OAE1 current drive is maximum, and on OAE2 minimum. As the timing interval progresses, mark-space (MS)OAE1 decreases as MSOAE2 increases, resulting in the relative brightness of the two LEDs varying to indicate the timing cycle progress. USE/ADVANTAGE - Timing indicator for domestic appliances such as battery chargers, Toasters and egg boilers. Does not require large number of LEDs, but achieves high resolution.
Patent DE-4203076-A1 (DE)
Title: Synthetic multifilament yarn process with prevented broken filament at high speeds
Inventor: SCHIPPERS HEINZ DIPL ING DR IN
IPC: D01D10/04
Filed: 1992-02-04
Abstract: Synthetic filament yarn is produced from spinning or a drawing zone in which the yarn is drawn at an angle around draw rolls, and then wound at a tension by a triangular lead to a traverse motion. Draw rolls angle, alpha, and the surface speed of the rolls, are arranged so that the rolls revolve at a greater speed than the yarn output speed, so that there is slippage around the surface, which is measured relative to alpha, without regard to the dynamic friction. Multifilament synthetic is pref. produced by spinning and combined into a yarn, which is fed through the guides at a short distance. Draw rolls take the yarn under the first roll and over the second roll, so the yarn contacts the surface of the rolls with a surface angle, alpha, of 90-270 deg.. Rolls are constructed with a special surface for their purpose, and are driven together at one speed, or independently and at different speed, according to yarn requirments. Lower guides form the triangular pattern, as the traverse motion winds the yarn on to the reels.

Title: Tyre fitted with withdrawable spikes in tread - has internal diaphragm which is cured circumferentially inside shoulder and can be pressurised to force spikes out through holes in tread
Inventor: SCHEIBENPFLUG HANS
IPC: B60C11/16
Filed: 1992-03-10
Abstract: A tyre has tread features from which spikes can be moved out or withdrawn again by means of a cover operated with compressed air. The cover is applied to the interior of the tread; it forms an inner chamber which can be filled with compressed air or vented again; the spikes are on the chamber side of the cover and they can move through holes in the tread. Pref. the tread (3) with the internal chamber (13) which is held at the same pressure as the tyre interior (21) or higher, and the spikes (7) are withdrawn i.e. in their normal position. Inside the main interior (21) is the pressure cover (5); this is cured in position on to the inside wall of the tyre by circumferential wedge-shaped pieces (9). This structure prevents excessive thickening at the critical shoulder area (4). Both the cover (5) and wedges (9) are cold cured i.e. contain suitable curing catalysts etc. A valve arrangement either admits the main tyre pressure or simply atmospheric pressure to the chamber (13). The tyre can be initially supplied with the holes (8) plugged so that it is then modified if required. ADVANTAGE - The design of the tyre is simple. It meets the latest technical specifications (unlike earlier types).

Title: Humidity reducing appts. for unheated rooms - uses Peltier element to condense water from cooled air and then warms dehumidified air from heat dissipated by element
Inventor: BORNHOLDT STEFAN DIPL PHYS
IPC: F24F3/14
Filed: 1992-08-17
Abstract: The damp air enters the dehumidifier through a vent (1) and passes down through a comb of ribs (2) in a vertical container. This air is cooled by a Peltier effect element (3), and the condensed water runs off downwards into a funnel (4) where it is collected. The other side of the comb array (6) is heated by the Peltier element and this means that the dehumidified air is drawn upwards by convection, exiting into the room through vent (7). An electronic sensor switches the appts. on when a preset humitity level is reached. ADVANTAGE - Dehumidifying with min. energy expense; no special room ventilation needed; compact construction; inexpensive to mfr.
