Title: Inflatable boat with double skin floor - has inflatable floor provided with built in stiffening spacing floor layers apart
Inventor: HOFFMANN ALFRED
IPC: B63B7/08
Filed: 1976-03-26
Abstract: The inflatable boat with special dimensional characteristics has sides (4), stern (5) and bow (7) sections made up of communicating lengths of inflatable tube. The cylindrical side- and stern sections have a dia. 1/4-1/3 of the boat beam and the length of the side sections is 3-5 times that dimension. The curved bow section tube (7) increases in dia. progressively to a max. at the bow of 1 1/2 times that of the side tubes. The floor (6) is double-skinned, the outer skin being flat when the sides are inflated. Between the two skins there are distancing threads (16) to keep the sides parallel when the floor is inflated and also helps to stiffen the floor. The single filling valve (9) for the side tubes is located in the lower part of the bow tube for protection. The floor filling valve is nearby.

Title: Tape recorder with circuit indicating signal level - has compander whose expander has auxiliary channel compensating amplitude reduction
Inventor: WIEDENROTH BERND ING GRAD
IPC: G11B20/00
Filed: 1976-04-13
Abstract: Signals to be recorded pass through a compressor of a compander unit, whose output is connected to the input of a signal circuit supplying the recording head and the level meter. Output signals of the reproduction circuit pass through the expander of the compander unit. The expander has an auxiliary channel whose output is connected to the output of the main channel with linear frequency characteristic, so that the signal compression is cancelled. Output signal of the expander auxiliary channel is applied during reproduction to the recording signal circuit connected to the compander output, with such phase and polarity, that amplitude reduction due to expansion is compensated in the recording signal circuit.

Title: Non-slip fabrics prodn. - by treatment with a foamed aq. dispersion of a film forming polymer and drying
Inventor: ROESSLER ERICH
IPC: D06M23/04
Filed: 1976-07-28
Abstract: High slip fabrics are rendered non slip by treatment with a foamed conc. to highly conc. aq. dispersion of a film forming polymer, followed by heat treatment. Pref. the textile is treated with 10-50, esp. 15-25 wt. % of the foamed dispersion, calculated as 100% polymer. The polymers are known materials based e.g. on vinyl acetate, vinyl chloride, vinylidene chloride, ethyl acrylate, acrylonitrile or 2-ethylhexylacrylate, or (esp.) copolymers based on ethylene, malic acid, acrylic acid, methyl methacrylate, butyl acrylate, styrene, butadiene, vinyl ether, 2-hydroxy-ethylacrylate and divinyl benzene. The polymer may also contain cross linking gps. derived e.g. from N-methylol (meth)acrylamide. The process is esp. useful for treating high slip fabrics such as those with a net- or gauze like construction and those with a low fibre count in the warp or weft. The use of foamed dispersions gives improved non slip characteristics while using less polymer than in prior art systems using unfoamed polymer dispersions.

Title: Echo suppressor with switches for telephone systems - has amplifier delivering constant output signal and controlling threshold detector
Inventor: PIERREL HANS-JOACHIM ING GRAD
IPC: H04B3/20
Filed: 1976-09-28
Abstract: The suppressor has a receiver responding to a control tone. The receiver has at its input a preamplifier stage followed by a wideband control amplifier without limiter effect. It delivers a constant output signal and controls a selective threshold detector with automatic band width switching. Its response threshold is only a little below the level of the constant output signal. The threshold value detector is connected through a double branch line unit (V4, V5) and uses an inverter unit (TS4) to control the echo trigger transistor. The method enables an enhancement to be obtained of the signal strength from marine cables and satellite communication signals.

Title: Self healing, wound capacitor - with outside metal layers separated by insulating layer and joined to terminals
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01G2/14
Filed: 1976-11-04
Abstract: A wound capacitor of the self-healing type is surrounded on its periphery by a first metal layer which is separated from a second metal layer by an insulating layer, the latter melts or its plastically deformed by an excessive temp. rise. One or both metal layers are connected to wires leading to outside terminals. If a fuse is connected to a circuit which is closed by a short-circuit between the metal layers, the capacitor is securely cut off from the supply thus preventing the capacitor housing bursting. The device is used in capacitor motors or fluorescent lamps.

Title: Gudgeon pin preventing piston rotation - has projecting end sliding in slot in cylinder wall
Inventor: PARO DANIEL
IPC: F16J1/16
Filed: 1976-12-29
Abstract: The pistons (1) slide in the cylinder block (2) and are driven by cams (8) acting on cam followers (4). Each cam follower (4) is connected to its piston (1) by a gudgeon pin (3). The gudgeon pin (3) is provided with a plastic cap which is pressed by a spring against the bottom of the groove (5) which is cut in the cylinder wall. The piston (1) is thus prevented from rotating without the use of any additional guiding devices. Where two pistons operate in parallel bores close to each other, a slot through the dividing wall replaces the groove (5). The end caps of the gudgeon pins are then arranged to abut against each other.

Title: Protective cover for nozzle in ink jet printer - is positioned during printing away from recording surface but can contact head when inoperative
Inventor: MORISHITA TANEJI
IPC: B41J2/165
Filed: 1977-06-07
Abstract: An ink jet printer has as cover by means of which the nozzle of the printing head can be protected or sealed off. The cover system (220-228) is positioned outside the region of the recording paper carrier. When no printing is taking place the printing head (101) is positioned so that the cover and nozzle are in mutual contact thereby sealing off the nozzle. When printing ceases the head is, e.g. displaced to the left and a signal is generated to turn a cam (222) through 80 deg.. This allows the cover holder (220) to be moved under spring action (221) towards the head's guide rail (217) so that the cover (226) contacts the outlet of the nozzle (101a).

Title: Vehicle hydraulic transmission with air-released main clutch - has torque converter lock-up clutch engaged at predetermined speed, and main clutch released by solenoid valve controlled air motor
Inventor: RUMJANCEV LEONID A
IPC: F16H61/14
Filed: 1977-08-19
Abstract: The vehicle transmission includes an air released main clutch connected between a torque convertor and multiple ratio gear transmission. A lock up clutch for the converter turbine and impeller is engaged by hydraulic pressure when an engine drive governor reaches a predetermined speed and opens a governor valve. The main clutch is released by a motor controlled by a solenoid valve which selectively connects the motor to a source of air pressure or to atmosphere via a restricted orifice and a normally closed air inlet valve. The restriction retarts the engagement of the main clutch when the engine is rotating below the predetermined speed, above which, the governor valve opens to engage the lock-up clutch and to open the air inlet valve so that the main clutch may be engaged at a faster rate.
