Patent DE-3808327-A1 (DE)
Title: Pivot-arm device
Inventor: MANNER ROLAND
IPC: F16M13/02
Filed: 1988-03-12
Abstract: The pivot-arm device provided for bearing, for example, a projecting screen is mounted on a table by means of a clamping securing means. The pivot arm of the pivot-arm device is freely rotatable about the axis of the pivot bearing, as a result of which there may be a risk of the table tilting up. The novel pivot-arm device is intended reliably to prevent uncontrolled pivot movements. In order to restrict the pivot path of the pivot arm, a first and a second adjustable stop are assigned to the pivot bearing of the pivot arm in order to restrict the pivoting movement and secure against rotation of the carrying arm. When the pivot arm pivots, these stops interact with in each case one counter-stop of the pivot bearing. By virtue of the fact that the pivot arm can be arrested, the pivot angle thereof can be restricted to a non-risk pivot range, with the result that the pivot arm cannot be pivoted beyond the edge of the table. When the table is displaced, the risk of it tilting up as a result of the pivot arm projecting can thus be prevented.

Title: Mixture-compressing two-stroke internal combustion engine
Inventor: MANZ PETER DIPL ING
IPC: F02B33/44
Filed: 1988-05-13
Abstract: A mixture-compressing two-stroke internal combustion engine (1) is described, which for each cylinder has two inlet ports (9, 10), controlled by timing devices (11, 12), for feeding fresh gas and at least one exhaust port (21, 22) controlled by a valve (23, 24) for the discharge of combustion gases. In addition, a charging unit (17) for raising the inlet pressure level is provided on the fresh gas side. In order to achieve the most favourable residual gas scavenging from the cylinder working chamber without the risk of fuel passing into the exhaust, it is proposed that, of the two inlet ports (9, 10), the one (9) be provided for the feeding of a mixture enriched with the fuel to be burnt and the other (10) for feeding in pure air. It is proposed that the assigned timing devices (11, 12) then be designed in such a way that the inlet port (10) to which pure air is admitted be opened earlier on in the power stroke than the inlet port (9) to which mixture is admitted. As a result it is possible to assign a fuel feed device (26) to the mixture-carrying inlet port (9), which device commences the fuel feed even before opening of the inlet port. <IMAGE>

Title: The method for composing bicycles and advertising surfaces
Inventor: BACHNICK MARTINA
IPC: G09F21/04
Filed: 1988-05-19
Abstract: To make more customers among the chance customers aware of special offers of specialised shops or retailers, in particular in quiet locations, the bicycle serves as advertising medium while maintaining its function as a vehicle which is to be displaced manually, and is placed predominantly in the main shopping streets with a lot of public business. The advertising surfaces, printed on or glued with advertising posters, having diverse formats, can be fitted in various manners to bicycles of any kind. Single-sided or double-sided, in one piece or unfoldable as desired, they can be glued over at any time so that the offers of the businessmen can be updated. So that the advertising on the bicycle is effective also during the night, the advertising surfaces can be brightly lit by means of illuminating bodies. In this manner, using bicycles for advertising purposes and in conjunction with advertising surfaces offers a valuable opportunity for the trade to access a larger clientele.

Title: Pumping device for liquids
Inventor: RODE PETER DR
IPC: H02K7/118
Filed: 1988-07-11
Abstract: Particularly in the case of domestic appliances such as laundry machines or dishwashers which carry water, split-cage motors are used virtually exclusively for driving the drain pump, which motors have a low efficiency and, in consequence, also occupy a relatively large volume. The use of a single-phase synchronous motor (1) having a permanent-magnet rotor (2, 3) results in a powerful drive with a small space requirement for the motor. The arrangement of a starting aid (10) in the form of a freewheel device (11, 12) provides automatic starting, despite a sliding bearing (5) and a shaft seal (9). <IMAGE>

Patent DE-3935395-A1 (DE)
Inventor: ATKINS THOMAS M
IPC: B60T8/48
Filed: 1989-10-24
Abstract: The system utilizes a separate solenoid-actuated, two position, three-way valve 29, (47, 53) in each controlled channel of the brake system for controlling the application of pressure to the respective wheel brake circuit. The valve includes a first port 29b connected to the controlled wheel brake(s), a second port 29a connected to an outlet of a hydraulic pump 33, and a third port 29c connected to the inlet of the hydraulic pump. The valve is only moveable between a first position wherein the outlet of the pump is connected to the wheel brake to increase pressure to the wheel brake, and a second position wherein the wheel brake is connected to the inlet of the pump to decrease pressure to the wheel brake. An electronic control cyclically moves the valve between the first and second positions during a predetermined time period to alternately increase and decrease pressure to the wheel brake. More specifically, the control generates a pulse-width- modulated signal to modulate the time periods during which the valve is maintained in either the first or second positions to control the effective pressure to the wheel brake to obtain a net increase, decrease, or constant pressure to the wheel brake during the predetermined time period. <IMAGE>
