Patent DE-3739932-A1 (DE)
Title: Bed frame
Inventor: KAMPS HEINZ
IPC: A47C20/04
Filed: 1987-11-25
Abstract: In a bed frame having a head part which can be put up at an angle about a pivoting axis on the frame plane, provision is made for the lower front end of the head part, lying close to the pivoting axis, to be arranged so as to be adjustable upwards out of the frame plane. The adjusting device intended for this can be constructed to work stepwise or steplessly. Consequently, in addition to the known upward-pivoting possibility of the head part, by adjustment upwards out of the frame plane a step-like or platform-like arrangement can be provided. Consequently, an ideal position for the cervical-vertebra region of a sleeping person can be set, and to be precise such that the cervical-vertebra region is supported such that it bends neither downwards nor upwards.

Title: Method for controlling an intercom system
Inventor: HUTT HANS-ULRICH
IPC: H04M9/00
Filed: 1988-03-05
Abstract: An intercom system is intended to be able to be controlled with the operating elements of terminals connected to a switching system, the same operating procedures being performed as those which are performed in setting up, for example, telephone connections. The intercom system is connected via interfaces directly to a communications switching system, e.g. a multi-user dealing room system. The control commands which are formed by the operating elements of the terminals connected to the switching system are forwarded by the central control device of this switching system directly to the intercom system. The method offers particular advantages if operators on workstations or answering stations, in particular multi-user dealing room systems, are able to speak directly to one another and set up the required connection using conventional operating procedures at the same terminal.

Title: Working method for the further processing of rolled bars continuously supplied by a rolling train and collected into groups and equipment for carrying out this working method
Inventor: BOEHMER BRUNO
IPC: B23D33/02
Filed: 1988-07-16
Abstract: A working method for the further processing of rolled bars which are continuously supplied by a rolling train and are deposited on cooling beds 1. From these, they are transferred to lateral roller tables 2, collected into groups and straightened in a single pass through a multi-strand straightening machine 4. After passing through the straightening machine 4, the rolled bars are cut jointly to predetermined lengths by successive cuts with a cutting device 5 and conveyed onwards. The feed motion of the rolled bars through the straightening machine 4 is interrupted when the lengths of rolled bar which have emerged from it reach a cutting position in the cutting device 5. The cutting of the predetermined lengths of rolled bar is then carried out with the rolled bars stationary and the feed motion of the remainders of the rolled bars in the straightening machine 4 is then continued to bring the subsequent lengths of rolled bar into the cutting position. <IMAGE>

Title: Auxiliary support for bearing the workpiece in a circular grinding machine, in particular a roll-grinding machine
Inventor: BAEHR THEODOR
IPC: B24B5/37
Filed: 1988-12-03
Abstract: For the auxiliary support in a roll-grinding machine there is provided a carrying ring 1 having clamping bolts 2 distributed uniformly in two circumferential rows. By means of these clamping bolts, the roll is centred within the carrying ring 1 and the entire auxiliary support. In this arrangement, the carrying ring runs with its running surface on supporting rollers 4 which are arranged to the left and right of the central vertical plane of the roll on a crossmember 3 which, in turn, is supported via a vertical column 9 on a hydraulic lifting element 30. The auxiliary support is displaceable transversely to the roll on an upper sliding surface of a carrying construction 24. This auxiliary support takes up at least 80% of the proportional roll weight at the respective roll end, so that the main-steady bearing arrangement only has to carry the remaining proportion. <IMAGE>

Title: Forced-draught gas burner
Inventor: OEHLER HEINRICH
IPC: F23D14/36
Filed: 1989-01-28
Abstract: In the case of a forced-draught gas burner, as homogeneous a fuel/air mixture as possible is to be produced, in order to achieve a reduction in the NOx formation during the combustion. A gas lance 6 has, for this purpose, in a first zone 8 seen in the flow direction gas outlet openings 7 with a small overall cross-section for producing a pre-mixture which is not yet combustible and in a second zone 9 gas outlet openings 7 with a sufficiently large overall cross-section to produce a combustible mixture. Both mixtures together result in a very homogeneous fuel/air mixture, the combustion of which leads to a reduced NOx formation. <IMAGE>

Title: Method for the operation of a two-stroke internal combustion engine
Inventor: BAUMUELLER ANDREAS DIPL ING
IPC: F02B75/12
Filed: 1989-04-05
Abstract: In a two-stroke internal combustion engine functioning with an intermittent fuel injection in the idling and partial load condition, in addition to the intermittent actuation of the injection nozzles the throttle valve is opened beyond the usual position in the transition to the idling or partial load condition and at the same time the fuel injected at a constant opening angle and constant volumetric flow. Reliable ignition of a lean mixture is thereby ensured in idling or overrun conditions, resulting in idling or overrun operation with advantageous smooth running, beneficial in terms of both consumption and exhaust emissions.

Filed: 1989-07-27
Abstract: In the measurement of pressure with a sensor element in the form of a piezoresistant resistance bridge on a silicon membrane, the aim is to amplify the differential voltage on the output diagonal of the resistance bridge independently of temperature. To ensure economical temperature-independent amplification of a differential voltage, both inputs (16, 21) of an amplifier (16) are connected alternately by means of a reversing switch (14, 23) to the input terminals (2, 3) to which the differential voltage (Ud) is applied and to the output of a second amplifier (20). The second amplifier (20) has an amplification of 1. Its own input (28) is connected to one input terminal (2) and its other input (29) is connected to its output (19). The output (30) of one amplifier (15) is connected alternately, with inphase rectification, by means of a third reversing switch (32) to a capacitor (34) arranged upstream of a Darlington stage (33) and to a reference potential. The Darlington stage is connected on the one hand via a resistor (26) to the output (19) of the second amplifier (20) and to earth; the amplified differential voltage can be tapped at the emitter resistor (39) of the Darlington stage (33). The circuit arrangement can be used in pressure transducers with a silicon sensor.
