Patent DE-4315914-A1 (DE)
Title: Vane pump
Inventor: ZELLNER UWE
IPC: F04C14/26
Filed: 1993-05-12
Abstract: A vane pump has the following features: There are vanes guided in a tube (2). The vanes slide along at their outer periphery in a cam ring. A flow-control piston (14) displaceable in a housing bore (12) projects into a pressure space (6). The pressure space (6) receives pressure medium via pressure pockets (7, 8) which are arranged in a pressure plate (5). The pressure space (6) is connected to an outlet (15) via a choke device. The choke device (17), with regard to its direction of flow, lies radially inside the two pressure pockets (7, 8) and at an angle to the longitudinal axis of the vane pump in such a way that - with regard to the direction of flow - it runs from a radially inner area to a radially outer area. <IMAGE>

Title: Fuel-injected two-stroke IC engine adaptive misfire control
Inventor: SCHOMMERS JOACHIM DR ING
IPC: F02D17/02
Filed: 1993-10-20
Abstract: A method for controlling a fuel-injected type two-stroke IC engine in the lower load range, involves interrupting the supply of fuel to the combustion space, or permitting the fuel supply to the combustion space, as a function of the operating parameters.For each injection procedure, the number of working strokes (required) for which fuel injection is to be interrupted is read out from a characteristic diagram (F), which depends on the operating parameters. The fuel supply is interrupted for (required) working strokes, and after the (required) working strokes, without fuel supply, have elapsed, the ignitability of the working gas is checked, and the characteristic diagram (F) is adaptively corrected as a function of the ignitability of the working gas.

Patent DE-4343704-A1 (DE)
Inventor: KOOPMAN PHILIP J
IPC: H04L7/10
Filed: 1993-12-21
Abstract: If a transceiver has a message to send during an idle medium condition, it transmits a jam pattern onto the medium for a predetermined time (based on maximum network propagation delay). If a transceiver detects a jamming pattern, it inhibits its own transmissions and waits for the next slot progression. If multiple transceivers begin jamming within a propagation delay of each other (within the network vulnerable time), their jamming transmissions will not destructively interfere with each other. When jamming ceases, all transceivers begin a slot progression. Thus, the end of the jamming period when all transceivers have finished jamming serves as a network-wide synchronization for the start of bus master arbitration, a token bus protocol or an implicit token slot progression. <IMAGE>

Title: Conveying holder for traffic signs
Inventor: SCHROEDER KLAUS
IPC: B60R11/00
Filed: 1994-04-19
Abstract: The invention relates to a conveying holder, in particular for traffic signs. Traffic signs are required for safeguarding roadworks on public roads. For this purpose, a certain number of traffic signs are taken along on the construction vehicles or road-maintenance vehicles. Some of these traffic signs are loose on the vehicles or are wedged between tools. As a result, the traffic signs are subjected to pronounced mechanical wear, leading to the traffic signs being rapidly scratched and hence unusable. The invention is based on the object of providing a space-saving holder which holds the traffic signs whilst they are being conveyed and secures them in such a manner that they are prevented from rubbing against one another while they are being conveyed. The holder is attached by the base frame to the vehicle tail board. After the shaft has been raised, the traffic signs are placed between the frame and the shaft. After the shaft has been lowered, the traffic signs are pressed by the pressing rollers against the frame by their own weight and are hence secured.

IPC: F01C19/06
Filed: 1994-11-09
Abstract: The round cylindrical combustion chamber volumetrically is four to ten times as large as the stroke volume of one of the compressor chambers (4). The fuel at the end of the compressed air input in the compressor outlet channel (5) issuing tangentially in the combustion chamber is injected into the combustion chamber by a high-frequency injection nozzle (6).The expander inlet (7) leading from the combustion chamber then opens when the fuel is burnt and then closes when the pressure in the combustion chamber drops again to the compression end pressure. The expander work chambers (8) are so large that the accommodated combustion gas expands up to the stroke end to the ambient pressure at the end of the power stroke.
