Filed: 1991-06-11
Abstract: ABSTRACT          The  stem  of  an  inching  valve  for  a  power-shift transmission,   particularly   for   lift   trucks,   is controlled   by   a   hydraulically-operated   piston whose  axis  is  distinct  from  and  parallel  to  the axis  of  the  stem  and  which  is  connected  to  the stem  by  means  of  a  mechanical  transmission.  The risk of contamination of the fluid used for operating the  piston  (which  is  the  fluid  of  the  vehicle's braking circuit)  by the oil used in the power-shift transmission is thus avoided.

Abstract: An ATM (Asynchronous Transfer Mode) cell format conversion system writes in a memory only a plurality of ATM cells each being 53 octets long and mapped in the payload fields of virtual containers VC-4-NC which have been multiplexed in the form of STM-N frames. A 1 octet long cell overhead is added to each of the ATM cells read out of the memory in response to base frame pulses which are synchronous to the STM-N frames, whereby the ATM cells are converted to l-octet added ATM cells each being 54 octets long.  The 1-octet added ATM cells and an idle cell are mapped in an imaginary 5 column groups x 9 rows matrix frame by frame and then outputted.  This allows each of the STM-N frames to be switched to otherwise processed on an ATM cell basis.

Abstract: A multi-stage rotary type compressor is constituted in such a manner that an electric motor and a plurality of compression elements to be driven by the electric motor are disposed in a closed container and the compression elements thus-disposed are sequentially connected in series. The compressor thus-constituted is arranged in such a manner that the space in the closed container is filled with the pressure discharged from the final stage. Furthermore, lubricating oil, the pressure of which is equivalent to the level of the pressure discharged from each compression element, is introduced into a back side chamber of a vane of each compression element to urge the back side of each vane with the pressure of lubricating oil. As a result, the wear of the tip end of the vane and the input loss are prevented. Therefore, satisfactory durability and compression efficiency can be obtained.

Abstract: An adjustable slew rate amplifier (26) in the input stage of an amplifier circuit (10) helps reduce off-channel frequency splatter. In instances where test sequences are input to an amplifier circuit that are used to measure maximum permissible input levels to the amplifier (34), inclusion of a low slew rate amplifier in the input loop further prevents the production of off-channel frequency splatter caused even by the input test sequence. The adjustable slew rate amplifier (26) is run at full slew rate, providing full-bandwidth amplification, during periods of normal circuit operation.

Title: Device for clamping recording substrates in sheet form
Inventor: BALZEIT RALF
IPC: H04N1/08
Filed: 1990-11-17
Abstract: The invention relates to a device for clamping film material in sheets to the recording drum of a reproduction arrangement and the method of operation of said device. The recording drum (1) has axially directed rows (6) of suction apertures for securing the image substrate (22) by a vacuum. In the walls (8) of the recording drum (1) there are suction channels (7), each interconnecting the suction apertures (5) of one row (6). In the recording drum (1) is arranged a vacuum distributor (25; 26; 27; 29) controllable by the rotary movement of the drum (1) which selectively connects the individual suction channels (7) or the appropriate rows (6) of suction apertures to a fixed vacuum pump (13). The vacuum distributor (25; 26; 27; 29) can be controlled in such a way that, during the clamping process, first of all the vacuum is applied to those rows of suction holes on which the leading region of the recording substrate (22) lies. This produces a high initial vacuum so that the recording substrate does not slip. Thereafter further rows (7) of suction apertures are connected in accordance with the greater extent to which the recording substrate is wound on the rotating recording drum (1) and vacuum is applied to them. The actuation of further rows (7) of suction apertures depending on the peripheral length of the recording substrate (22) is terminated at that row (7) on which the end region of the substrate (22) lies. The device especially makes it possible to clamp and secure large-size recording substrates on the recording drum (1) without creasing and slip.

Inventor: DOSHI BHARAT T
IPC: H04L12/56
Filed: 1992-06-23
Abstract: Congestion in a high speed connection oriented packet is avoided by an in-call negotiation scheme for reserving bandwidth for real time calls and reserving buffer capacity for bursty calls. For a real time call, a centralized call controller in each switch in the network determines which of its outgoing trunkshas available the peak bandwidth needed to accommodate the call. If so, the callrouting is set up so that the call is directed through that trunk. Calls involving bursty data cause the call controllers in the switches to set up the routing of the call and allocate some minimum bandwidth on selected output trunks. A special packet which contains an indication of a requested buffer capacity is produced by the call transmitter and sent to all the switches along the route. At each switch along the route, a check is made to see if there is sufficient unallocated buffer capacity on associated trunks equal to the requested capacity. If so, that amount of buffer capacity is allocated to the call and the special packet is passed unchanged to the next switch. If that amount of buffer capacity is not available, then the switch may refuse the call by placing an indication of such refusal in the special packet and which is passed to the next switch. When the special packet has reached the intended destination of the call, an acknowledgment packet is produced and sent back to the origin. If the request for buffer capacity has been completely denied by one of the switches or if a smaller amount of requested buffer capacity has been written into the special packet by one of the switches,the acknowledgment packet deallocates the excess previously allocated buffer capacity on its trip back to the origin and notifies the transmitter of the buffer capacity which has been allocated along the route of the call, if any. If the call has not been completely denied, the data making up the call is then sent along the prescribed route at a rate which will not cause an overflow of the buffers allocated to the call.
