Patent DE-3200872-A1 (DE)
Title: Electronic balance
Inventor: KNOTHE ERICH ING GRAD
IPC: G01G7/02
Filed: 1982-01-14
Abstract: In electronic balances of high definition, for example on the principle of electromagnetic force compensation, the sensitivity has to be checked and, if appropriate, corrected after each change of location and otherwise from time to time. For this, the storage and change of a calibrating factor is necessary. So that non-volatile EAROMs or nv-RAMs with their limited number of recording cycles can be used for this, the invention proposes the division of these memories into part regions which are used in succession under the control of change-over means. At the same time, the number of recording cycles is likewise also stored, and after the maximum number of recording cycles has been reached the change-over means are activated so that there is a change-over to a new part region of the memory. <IMAGE>

Patent DE-3237606-A1 (DE)
Title: Electronic level switch with self-protecting control unit
Inventor: NORDT GUENTER OSKAR ING GRAD
IPC: G01D21/00
Filed: 1982-10-11
Abstract: The circuit arrangement is based on the protection philosophy that an unambiguous function monitoring can only occur if a predeterminable variation of the output variables with time is monitored in the active components. By using the change in these output variables as switching commands for subsequent or preceding switching members and corresponding functional dependence, a self-protecting circuit with unambiguously defined output signal is obtained for the fault case with a simple fault. Such a condition is satisfied since all switching components of this circuit arrangement are periodically operated and thus dynamically monitored for functional capability.

Next to each of the first two chambers (28, 31), other chambers (29, 33) are provided, which are delimited on the sides away from the first chambers (28, 31) by membranes (9, 16) differing with respect to selective permeability from the membranes of the first chambers (28, 31) and which are filled with liquids, which prevent the formation of sparingly soluble products. <IMAGE>
Patent DE-3242638-A1 (DE)
Title: Waveguide for radio-frequency transmission
Inventor: YOSHIMURA HIROFUMI
IPC: H05B6/70
Filed: 1982-11-18
Abstract: The invention relates to a waveguide having an intrinsically tapering cross-section as is required in particular for transmission of the radio-frequency energy produced by a radio-frequency oscillator into the interior of the heating space of a radio-frequency heating apparatus, in order to reduce the structural height and to increase the compactness of the apparatus. In order to avoid an expensive deep-drawing process for producing such a waveguide, the side wall of the waveguide (20) which runs in the E-plane of the radio-frequency energy to be transmitted is constructed such that it is divided by surface parts (24, 27, 28), which makes it possible to produce the waveguide as a stamped part. The slots (29, 30) which exist between the surface parts are held at a width of less than 1/10 of the wavelength used. <IMAGE>

Inventor: GANSER HANS-GUENTER
IPC: H05B41/231
Filed: 1982-12-11
Abstract: A circuit arrangement for operating a high-pressure gas discharge lamp (3) with a pulsatory direct current produced from an alternating voltage supply (A, B) via a full-wave rectifier (1). The output of the full-wave rectifier is shunted by a series arrangement of a diode (4) and a capacitor (5). The capacitor (5) has a value of 10 nF to 1 mu F and a resistor (6), which is high-ohmic with respect to a current limiter (2) in series with the lamp (3), is connected in a current circuit between the end of the capacitor facing the diode and the lamp (3). As a result, a low re-ignition voltage is attained during the head-up phase of the lamp.

Title: Portable speech unit for persons with speech impairment
Inventor: GUTWENIGER OTTO
IPC: G10L13/047
Filed: 1982-12-15
Abstract: The invention relates to a small speech unit, which enables speech by calling up mainly syllables, made up of vowels and consonants of a language by keys (Fig. 2) of static speech memories (14) by means of a speech processor (13) using a binary number register to locate the corresponding speech elements. This is rendered possible only through the progress made in electronics in storage and recording using digital values, and replaces storage on audio tapes used hitherto for the same purpose. As a result, the unit has virtually no moving parts and is much more reliable, much smaller and much less expensive. The symmetrical disposition of the keys (1) (Fig. 1) enables easy two-handed operation of the unit, either hanging on the chest or lying on a table. The words can be input using keys for syllables, vowels and consonants and, after being added together, can be called up using a key (8) or can be immediately reproduced directly at the push of a button in the loudspeaker (4), whereby the speech is rendered more lively. <IMAGE>

Title: Screen-like covering for roof gutters
Inventor: HOFFBAUER LOTHAR U
IPC: E04D13/076
Filed: 1983-05-05
Abstract: Soiling in roof gutters prevents smooth water discharge. In order to prevent soiling screens are required. Screens only work when they are clean. The invention of the screen-like covering for roof gutters is based upon the fact that, by way of its shape and the way in which it is attached in the second or following rows of roofing tiles, it permits soiling to trickle away or to be rinsed off by rainwater. The screening effect is thus retained over a considerably longer period of time.
Patent DE-3318797-A1 (DE)
Title: Cellular-wheel feeder
Inventor: BEIRLE WALTER
IPC: B65G53/46
Filed: 1983-05-24
Abstract: In cellular-wheel feeders which are used as feeders for pneumatic conveyor pipelines which are under pressure, the unavoidable stream of leaked air picks up the fines of the powdered or granular conveyed material and carries it into the aspiration section. This causes a loss of a percentage of the material, environmental problems or additional costs for the filtering. With the invention a cellular-wheel feeder design is proposed which permits elimination, to a very substantial extent, of the fine material, carried off by the stream of leaked air, from the stream of leaked air while it is still in the feeder region, and return of the fine material to the stream of material. This is achieved by the application of guiding means and by designing a system of channels in the feeder attachment, within which the particles of material which have been carried off are separated from the stream of leaked air 1. by multiple deflection of the stream of leaked air with a movement component pointing transversely to the force of gravity or with one movement component pointing transversely to and another pointing in the direction of the force of gravity, 2. by expansion and 3. via the rebound effect, and are then guided into the cells of the cellular wheel together with the stream of material.

Title: Control method for charging a hot water tank or for heating at least one room
Inventor: TAAG JUERGEN
IPC: G05D23/20
Filed: 1983-08-01
Abstract: The present invention relates to a control method for heating at least one room or for charging a hot water tank which is operated with overnight reduction. Within a controllable period before the instant of switchover to the overnight reduction, the rate of change of the actual value is interrogated when the desired value has been reached by the actual value, and the heating of the room or the charging of the tank is suppressed before the instant of switchover when this rate of change leads to a system deviation in the desired value which is within a selectable shortfall at the instant of switchover. This prevents the rooms or the tank from being heated up once again to the original desired daily value shortly before the overnight reduction. <IMAGE>
