Title: Hydraulic control device for an automatic motor vehicle gearbox
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/02
Filed: 1984-06-28
Abstract: The hydraulic control device has a main pressure control valve (1) for generating a main pressure as a function of the load state of the vehicle engine for the operation of control means of the gearbox, the main pressure control valve having a control piston (10), which is loaded on one side by an engine load dependent control pressure supported by a spring (11) and on the other side by pressure medium pressures bearing on stepped rocker surfaces (21a to 23a). In addition a control valve (3), inserted between a manual control valve and a control element (2) assigned to the forward gears of the gearbox, is provided, which ventilates the pressure admission line (6) leading to the control element when the accelerator pedal is released. In order, in a control device of this type to achieve a speeding up of the re-engagement process of the control element (2) at least when standing still or at very low speeds of travel of the vehicle, it is proposed that a pressure admission chamber (27) assigned to one of the rocker surfaces (21a to 23a) of the main pressure control valve (1) be connected to the pressure admission line (6) leading to the control element (2). In this connecting line (8) leading to the pressure admission chamber (27) it is proposed that a reversing valve (4) be arranged which in a first position ... Original abstract incomplete. <IMAGE>

Title: Bayonet closure having a sealing element for closing a container
Inventor: LOUVATIERE JIMMY
IPC: B65D41/04
Filed: 1984-07-24
Abstract: A bayonet closure having a sealing element is proposed which has a double lip and a central elevation whose upper terminating surface lies above the plane of the flange connected to the double lip. The rotation of the closure cap by interaction of the inclined webs arranged on it with the inclined ribs of the neck causes deformation of a part of the double lip which is pressed in a sealing manner against the orifice of the neck. The rotation of the cap is limited by vertical webs which act as a stop, are arranged at the end of the inclined webs and abut the inclined ribs. The rotation of the closure cap in the opening direction causes an axial displacement to act on the closure cap due to the elasticity of the sealing element. When the inclined webs are disengaged from the inclined ribs, the pressure acting inside the container causes the closure cap to be pushed out. The closure is therefore particularly suited for closing bottles containing carbonated liquids.

Title: Hydraulic brake system for motor vehicles
Inventor: BECKER HORST-PETER
IPC: B60T13/16
Filed: 1985-06-29
Abstract: A hydraulic brake system (2) for motor vehicles is created with a brake master cylinder and a hydraulic booster (4) for the power actuation of the brake master cylinder, the hydraulic booster (4) having an operating piston (26) and a booster piston (16), and with a servo-pressure pressure medium source, especially a pressure medium pump (6) and with a pressure control valve (9), which by simple means without costly valve systems feeds a foot force-dependent pressure to the brake booster (4). This is achieved in that a working chamber (28), to which pressure medium is admitted, is defined by the operating piston (26) and booster piston (16), which chamber is connected by way of a pressure medium line (40) to the pressure control valve (9), so that when the operating piston is operated a pressure is built up between the operating piston (26) and the booster piston (16), which is fed by way of the pressure medium line (40) to the pressure control valve (9), in order to control the pressure delivered to the brake booster (4) by the pressure medium source (6) as a function of the foot force. <IMAGE>

Patent DE-3537096-A1 (DE)
Title: Data transmission system
Inventor: KADIN JOSEPH
IPC: H04B1/713
Filed: 1985-10-18
Abstract: A frequency hopping data transmission system is described. A pseudo-noise generator generates two frequency hopping codes at the transmitting end according to the two states of a binary data signal to be transmitted. A modulator connected downstream of the pseudo-noise generator, controlled by the binary data signal, forwards either the one or the other frequency hopping code to a frequency synthesiser. A further pseudo-noise generator which is synchronised with the pseudo-noise generator at the transmitting end generates the same two frequency hopping codes at the receiving end and controls the tuning of the receiver section to the reception frequency which is to be expected at the respective time. <IMAGE>

Title: Method and device for monitoring the cleaning state of food lines for free-flowing foods
Inventor: NERB WOLFGANG DIPL ING
IPC: B08B9/032
Filed: 1985-10-29
Abstract: A method for monitoring the cleaning state of a line for free-flowing, in particular liquid, foods, and a device for this purpose are distinguished by the fact that a measuring sensor (18) is arranged in the line (12, 14), which measuring sensor responds to the electrical conductance of the liquid in the line. If the line is cleaned using a cleaning agent, for example an acid, this change in the conductance is recognised by the measuring sensor (18) and stored in a control system (16). If after a fixed period of, for example, two weeks, the line (12, 14) has not been cleaned, an acoustic and/or visual warning is firstly given to the operator of the line system and, if still no cleaning of the line is carried out within the fixed period, a shut-off member (20) is actuated by the control system (16) which interrupts the flow of liquid in the line. The blocking of the line is maintained until the line has been cleaned. <IMAGE>

Abstract: The invention relates to a method for processing legumes, starch sources or the like to give feedstuffs for monogastric animals. The invention is based on the object of creating a method by the aid of which legumes, starch sources or like material can be processed to give a feedstuff which has a high digestibility and thus has a high ability to supply energy. In achieving the object, a method according to the invention has been developed in which the material is broken by fluted rollers and is then subjected to a thermal treatment in a temperature range from 75 DEG  to 105 DEG C. In the method according to the invention, the material is preferably flaked after the thermal treatment, pelleted after flaking and cooled after the pelleting. Before flaking, the material is preferably dried.

Title: Hollow spherical joint with sliding lock
Inventor: HILLE ERICH DIPL ING
IPC: F21V21/29
Filed: 1986-02-08
Abstract: There is a very particular lack in the lamp building production branch of the electric industry of spherical joints which render it possible for cable lines or similar to be guided through invisibly without loss of movement, for lamp parts to be influenced in their mobility up to complete blockage in a manner capable of stepless control, for the angle of movement to be increased, and for assembly to be facilitated. The innovation takes account of all these defects by providing cable cavities (Parts 1 and 4) in a compact system (Fig. 1, 2 and 3), by effecting a sliding lock with the aid of incisions in the joint sleeve (Part 4) and the brake linkage (Part 5), and finally by achieving an angle of movement of 60 degrees by taking account of the individual torques. Dividing the ball cup (Parts 2 and 4) enables the lamp body to be mounted without difficulty. The mounting bores were arranged (Fig. 2) such that they guarantee the greatest possible stability in the smallest space. Their counterbored holes for screw heads were partially provided in a halfround fashion in order to provide a variety of screwing angles frequently required. The system can be produced both from plastics and from aluminium alloys. <IMAGE>
