Patent DE-3302294-A1 (DE)
Inventor: RIZK REDA R
IPC: F02M59/36
Filed: 1983-01-25
Abstract: A fuel injection arrangement for air-compressing, spontaneous-ignition, internal combustion engines. The arrangement includes at least one electromagnetic control valve via which a high-pressure channel of a fuel injection pump can be connected with a low-pressure channel. The control valve includes a valve body which is in the form of a piston valve, is spring-loaded, and is axially movable in a housing chamber which is provided with at least one connection on the high-pressure end, and with a connection on the low-pressure end. The piston valve is in operative connection with an electromagnetic adjusting device which can preferably be controlled by an electrically-operating data processor. The piston valve region on the high-pressure end is delimited by a valve seat and has a fixed diameter which corresponds to the diameter of the valve seat. The piston valve region on the low-pressure end has a diameter which is less than that of the piston valve region on the high-pressure end. The housing chamber taken in its entirety is sealed off in such a way as to be resistant to high pressure. The chambers on the low and high pressure ends can be connected by at least one line. The inventive fuel injection arrangement is characterized by an extremely stable behavior of the control valve and an absolute sealing in the closure position of the piston valve, so that the fuel injection arrangement itself is operational at the highest injection pressures.

Title: Venting and boiling valve
Inventor: OCHS HUBERT DIPL ING
IPC: A47J27/09
Filed: 1983-05-27
Abstract: The subject matter of the invention is a venting and boiling valve for a pressure cooker, which valve closes and opens depending on the conditions occurring during cooking inside the pot. The intention is to guarantee the desired course of the cooking process satisfactorily using simple means, which is not always guaranteed in a valve body which closes as a function of pressure. According to the invention, the valve body is moved as a function of temperature. The temperature anywhere in the pot is reliably not less than the temperature reached in the lid region of the pressure cooker. In a preferred embodiment, the valve body is mounted on a lifting piston of a cylinder containing an expansion medium.

Title: Circuit arrangement for automatically adapting the volume of a loudspeaker to an interfering noise level prevailing at the loudspeaker location
Inventor: LEYSER KLAUS DIPL ING
IPC: H03G3/32
Filed: 1983-06-18
Abstract: A circuit arrangement for automatically adapting the volume of a loudspeaker to an interfering noise level prevailing at the loudspeaker location is specified, particularly for mobile radio receivers such as car radios or the like, which exhibits an adjustable function network (18) with a transfer function, which generates a correcting variable for a volume controller (11) in dependence on the interfering noise level in such a manner that the useful voltage level at the loudspeaker is logically combined with the interfering noise level via a predetermined characteristic. For the purpose of adapting the volume to the interfering noise level in accordance with an individual characteristic which can be automatically adapted to the situation in an internal vehicle space and to the requirements and the auditory sensation of the motor vehicle passengers, a curve adaptor (19) is connected to the function network (18) and a volume control (12), which adjusts the function network (18) in such a manner that the predetermined characteristic can be modified at least section by section in dependence on the operation of the volume control (Figure 1). <IMAGE>

Title: Arrangement for drying tobacco
Inventor: FLASDIECK JOERN DR DR ING
IPC: A24B3/04
Filed: 1983-06-25
Abstract: The vapours (with expelled moisture, preferably highly enriched drying air) from a drier for tobacco are fed to a heat exchanger, in which they heat fresh drying air. The heat exchanger is advantageously operated in such a way that a part of the moisture in the vapours, which are at the saturation limit, condenses on cooling; the heat of condensation thus recovered gives a good energy balance. <IMAGE>

Title: Mounting of a lower roller for spinning or twisting machines of great length
Inventor: GEISLER HARALD
IPC: D01H5/56
Filed: 1984-05-11
Abstract: The invention relates to a mounting of a lower roller for spinning or twisting machines of great length, the lower roller being separated into two lower-roller parts, being arranged in stands and mounted in rolling bearings and being driven in the same direction of rotation and at the same rotational speed at the start and at the end, in each case by means of a gear. The object on which it is based is to avoid reducing the production of the machine and to lower the outlay for the mounting of the lower-roller parts. This object is achieved in that the lower-roller parts (2, 3) of the lower roller (1) are received at the parting point in a common stand (4), and a rolling bearing (5, 6) is arranged on each lower-roller part (2, 3) at the parting point. Fig. The invention achieves the technical effect that the full spindle speed of the machine is maintained and the mounting of the lower-roller parts is simplified.

IPC: E04B2/74
Filed: 1984-05-16
Abstract: In order to erect room divisions, in particular in the case of open-plan offices or trade-fair halls as so-called partitions, in a variable manner and to be able to change them at will at any time, wall panels are provided at the upper and lower edge with perforated rails, the spacing between the perforations being matched to the wall-panel thickness as the perforation-spacing pattern.

The connecting plates can be longitudinal strips with which the panels can be arranged in rows. The connecting plates can also be perforated crosswise or at an angle and also in the shape of a T, such that angular erections or branchings can be effected at any point on the perforated rails of the wall panels. The desired room divisions then result by arrangement in rows and by the angular, crosswise and T-shaped branchings.

Title: Blowing device for sheet feeders
Inventor: FUEGMANN UTA DIPL ING
IPC: B65H3/48
Filed: 1984-07-06
Abstract: The invention relates to a blowing device for sheet feeders of sheet handling and sheet processing machines, especially printing presses. The aim of the invention is to improve decollation or separation of sheets. The object is to produce a blowing device which ensures guiding of sheets which acts on the whole surface of the sheet and is flutter-free, and in which the nozzle effect does not occur and the danger of collision with the sheet raised by the suction lifting device and the suction lifting device itself is eliminated. According to the invention, the object is achieved in that a blowing nozzle which rotates about a vertical axis in the region of the rear edge of the stack and the air outlet aperture of which is automatically altered by the quantity of conveyed material in an approximately proportional manner is provided. The blowing nozzle which adapts to the stream of blowing air in each case is cone-shaped. The air outlet aperture of the blowing nozzle has a rectangular cross-section. As the stream of blowing air increases, the air outlet aperture becomes larger, the width of the latter remaining the same, only its height being altered. The blowing air is only active while the rotating blowing nozzle is inserted between the stack of sheets and the sheet raised by the suction lifting device. <IMAGE>
