Title: Loudspeaker amplifier circuit for telephone appts. - has voice signal amplifiers in each channel controlled by two FETs
Inventor: FORDAN GUENTER
IPC: H04M9/10
Filed: 1977-03-07
Abstract: The loudspeaker amplifier circuit is intended for telephone apparatus and has voice signal amplifiers (EV, SV) in each channel in place of the channel relative switchable attenuators, control amplifiers and voice level comparators. These voice signal amplifiers are controlled by voltages derived from part of the voice signal at the amplified loudspeaker (L), using two field-effect transistors (FT1, FT2). The voice signal amplifier in the reception channel (EV) has additional voltage supplied by the second control field-effect transistor (FT2). Thus the voice signal input in this channel is AC connected. The other transistor (FT1) in the transmission channel (SV) is DC coupled with amplifier input, affecting the working point.

Title: Aminoplast resin modified with 5,5-di:methyl-hydantoin - useful in prodn. of non-cracking decorative surfacing sheets for chipboard
Inventor: SCHEDLITZKI DIETMAR DR
IPC: C08G12/40
Filed: 1977-06-03
Abstract: (I) is added as modifying agent to aminoplast precondensates used for surfacing wood based panels. The (I) is added at 1-20 wt.% on the amino resin. The laminating resin used is pref. a melamine-formaldehyde resin. The (I) may be condensed into the resin during mfre. or it may be added to the impregnating bath. The modified aminoplast resins are used for impregnating overlay papers of the type used for surfacing wood based panels such as chipboard. (I) has an excellent plasticising effect in the cured amino resin and gives cured resin films having excellent water and weather resistance coupled with increased resistance to cracking and cracking. (I) does not retard the cure of the amino resin or cause instability of the impregnating bath, and does not cause contamination of the drier used to dry the impregnated laminating film. The flow of the molten resin is improved and the cured resin has improved transparency, so that the printed pattern of decorative overlay papers is given increased brilliance.

Title: Furniture castor with brake - has roller mounted on carrier which is biassed downwardly away from brake element
Inventor: SCREEN STAFFORD THOMAS
IPC: B60B33/02
Filed: 1978-01-12
Abstract: The castor has a roller (20) mounted on a carrier (17) which is structurally separate from the castor body (14), the body being adapted to mount the castor on an article of furniture via an attachment member (11).

Title: Scraper chain conveyor for mines - has gas collector chambers at intervals between slide and floor plates with chamber connected via common collector to exhaust system
Inventor: RENNER KURT DR ING
IPC: E21F7/00
Filed: 1978-04-24
Abstract: The scraper chain conveyor is for deep mines, having trough sections with slide and floor plates assembled together. The floor plates each have openings leading to the bottom run, and the space between them and the slide plates forms a gas collector chamber connected to a gas exhauster system at the side. At intervals in the lengthwise direction of the conveyor between the slide and floor plate are gas collector chambers. Each collector chamber is connected via a common chamber to the exhauster system, and shaped so as to give even loading of the exhaustion openings, which are situated on arcs about a central point. The latter is on the extended axis of the exhaustion passage in the collector chamber. The portion of each collector chamber towards the coal face has more openings than that towards the discharge point.

Title: Probe which measures electrical conductivity of liq. - uses coils to generate and detect induced voltage in liq.
Inventor: PRANZAS GUENTHER
IPC: G01R27/22
Filed: 1978-05-26
Abstract: The equipment measures the electrical conductivity of fluids. a probe (9) containing a primary (1) and a secondary (4) parallel coil is inserted into the fluid. The primary coil induces a voltage in the fluid in the probe holes (12, 13) between the coils and the secondary coil which is tuned by the resistor (6A) and the capacitor (6) to oscillate at the primary frequency which detects, amplifies and displays (7) the signal. Both coils are capacitatively screened and inductively screened from each other. A temp. probe (14) alters the measurement voltage (2) to compensate for temp. variations.

Patent DE-2855366-A1 (DE)
Inventor: WATANABE KAZUO
IPC: D05B3/06
Filed: 1978-12-21
Abstract: The sewing machine has a device for forming a stitch (DV) comprising an upper drive shaft turned by a motor (M) of the machine and generating one synchronisation pulse per revolution. A static memory (ROM) stores a certain amount of pattern control data comprising the control data for forming a buttonhole. The static memory is addressed sequentially to extract the data controlling the pattern per revolution of the upper drive shaft. The data will drive the device forming the stitches (DV). A counter adds the synchronisation pulses generated by the device forming the stitches (DV), that is to say the number of stitches to be formed during which a stitch pattern is produced. A memory (L1, L2) stores the number of synchronisation pulses added by the counter (C). Comparison means (COMP1, COMP2) compare the counts of the synchronisation pulses by the counter (C) and the number of stitches stored in memory (L1, L2) in order to cyclically form a buttonhole with a defined number of stitches and a pattern selector (PS) operating selectively in order to address the control data for the buttonhole (I1, I2) stored in the static memory (ROM). <IMAGE>

Title: Electrostatic loudspeaker with overlapped transducers - uses smaller transducers in layers mechanically coupled for large unit equivalent output
Inventor: REICH STEFAN
IPC: H04R19/00
Filed: 1979-01-09
Abstract: The electrostatic loudspeaker of reduced size is obtained by using small transducers, one behind the other in a staggered honeycomb overlap formation. All transducers operate in phase, and the depth of the stagger does not cause distortion because the pneumatic effect from all transducers combines to produce the output of a larger speaker system. All the grid electrodes (10, 12, 14; 11, 12) are mechanically linked together alternately and to each output terminal of the amplifier (6). The polarisation electrodes are again alternately connected (1, 3; 2, 4) and either positively or negatively polarised from the local mains (5). The final configuration is a complete interlace structure of amp output, +ve polarisation, amp second output, -ve polarisation, amp output etc. throughout the structure. The construction may be used for either loudspeaker or headphones.
