Abstract: 1,228,229. Reinforcing edges; laminated fabric. KOBUNSHI KAKO KENYUJO K.K. 19 Dec., 1968 [19 Dec., 1967], No. 60301/68. Headings B5K and B5N. [Also in Divisions D1-D2] A split fibre non-woven fabric 41 is made by passing one or more split fibre webs 13 through one or more flat air ducts 17 through which an air current flows to loosen and spread the web and blow it against a rotating element 20 to deposit a uniform density web thereon. The web is then removed from the rotating element as a warp web and a weft web 30, made by the same process as the warp web, is cast across the width of the warp web by blowing compressed air passing through a further flat air duct. The compressed air is then stopped and the weft web is cut whilst simultaneously depositing the weft web on the warp web by suction applied from beneath the travelling warp web. The casting of the weft web is repeated and the webs are bonded together with a liquid binder. The fibres in the web may be of polypropylene polyethylene, polyvinyl chloride, polyacrylonitrile, polyvinyl alcohol, polyvinylidene chloride, polyamide, polyester, or a copolymer or derivative thereof, regenerated cellulose or cellulose ester. The binder can be applied to the webs prior to and/or after casting the weft web on to the warp web. The binder may be the same as the polymer of the fibres, or may be copolymer of the same monomer used in the split fibre webs and a momer having an acid, hydroxyl, chloride, ester, amide, or cyanida active group attached thereto, or may be a chlorinated polymer or organic titanate. The weft web portions may overlap each other slightly. The fabric can have polyethylene selvedge tapes 33, 34 applied to the edges thereof. The web can be passed through an oven 37 supplied with hot air and pressed with rollers 38, 39. The non-woven fabric can be embossed with a canvas sheet which may produce tiny holes in the fabric, Ex. 2, or it can be crumpled and bulked by nipping it between a rubber and a fluted roller (Ex. 6).  A plurality of layers of the non-woven fabric formed may be stiched and stuck together under pressure. The non-woven fabric may be sandwiched between two paper sheets bonded with the same binder as used to bond the warp and wefts together. The non-woven fabric may be bonded to either side of a polyethylene film by hot pressing (Ex. 3). The non-woven fabric may be bonded between conventional non- woven fabrics (Ex. 4). The non-woven fabric may be spread on the screen of a paper-making screen and have pulp and size passed therethrough whilst the screen is vibrated. The fabric-reinforced paper product is then dried and hot-calendered (Ex. 6).

Abstract: 1,228,647. Inductive control systems. SABA SCHWARZWALDER APPARATE - BAUANSTALT AUGUST SCHWER SOHNE G.m.b.H. 11 June, 1968, No. 27684/68. Heading H4U. In a control system, e.g. for automatic door opening, oscillations of different characteristic frequencies are produced by a plurality of oscillators and operating signals are produced by a detached passive element comprising a corresponding plurality of resonant circuits which are tuned respectively to the oscillator frequencies and are brought into inductive or capacitive coupling with the oscillators, a control signal being effective when all the operating signals are coincident. The passive element may be in the form of a key, and the resonant circuits may be embedded in moulded resin or the like and spaced by the distance between aerials connected to the oscillators. As shown, characteristic frequencies fa, fb are generated by oscillators 2, 2<SP>1</SP>, respectively, and frequency-swept by means of a low-frequency generator 3, e.g. at 2 c/s. When two resonant circuits tuned to frequencies fa, fb are brought into the vicinity of aerials 1, 1<SP>1</SP>, the output of the oscillators 2, 2<SP>1</SP> is briefly reduced, resulting in pulses of highfrequency oscillations which are detected at 4, 41. The aerials may be arranged in pairs for each oscillator so that the fields at a distance cancel. The low-frequency pulses from the detectors are fed via bandpass filters 7, 7<SP>1</SP> and amplifiers 8, 81 to rectifiers 9, 9<SP>1</SP>, the resulting voltage being smoothed and amplified at 10, 10<SP>1</SP> and supplied to an amplifier 11 controlling a relay 12 connected, for example, to a door opener. Only when the two signals coincide and exceed a theshold value will the relay be operated. If disturbance signals are present, which may be arranged to be produced by a burglar detector, they are separated from the signal pulses by high pass filters 13, 13<SP>1</SP>, ampli. fied at 14 and supplied to rectifier 15 which is oppositely poled to rectifiers 9, 9<SP>1</SP>; The rectified voltage from 15 is amplified and smoothed at 16 and causes the input to amplifier 11 to be shortcircuited so that the relay does not operate. An alarm may be operated at the same time. Low pass filters 5, 5<SP>1</SP> extract the D.C. component from the output of demodulators 4, 4<SP>1</SP> which via amplifiers 6, 6<SP>1</SP> controls the amplitude of the oscillations from oscillators 2, 2<SP>1</SP>, respectively. It is stated that, in a modification, a further frequency modulated oscillator is controlled to produce from the disturbance signals frequencymodulated oscillations distinguishable from the signals produced by the characteristic frequencies, which may be used as before to disable the output circuit.

[Also in Division H4] A rat repelling device comprises a waveform generator for electronically producing a signal above the human audible range which simulates the sound made by a frightened rat, the signal being amplified and fed to at least one output transducer with an automatic gain control circuit for maintaining a constant output level. Circuit. The output of a relaxation oscillator 10 comprising a unijunction transistor 34 (Fig. 2) and operating at an adjustable frequency of about 40 kHz is amplitude modulated by the output from a common emitter amplifier 11 whose output consists of 50 millisec trains of pulses of about 20 kHz, separated by about 20 millisecs. The pulse trains are produced by a multivibrator circuit 13, having NPN transistors 76, 77, which modulates the output of an adjustable 20 kHz relaxation oscillator 12 comprising unijunction transistor 51. The 40 kHz amplitude modulated signal is amplified by transistor 96 in a common emitter amplifier 14 and then passed through transistor 112 operating in a constant gain control amplifier circuit, the signal is then amplified in a driver amplifier 19 and also by NPN transistor 125 and PNP transistor 126 operating as an output push-pull amplifier from where the signal is fed by means of one of the jack sockets 136 to one or more transducers. The output signal to jack sockets 136 is fed through a decoupling resistor 141 and a rectifying circuit comprising diodes 137, 138 to the base of transistor 147 of a control voltage inverter amplifier 22. The collector 152 of transistor 147 is directly connected to the base 153 of transistor 113 whose load impedance comprises resistors 162 and 163 in series with diode 109. The impedance of diode 109 depends upon the collector current in transistor 113 and acts as a shunt to the signal output from collector 107 of transistor 96 in the composite signal buffer amplifier 14 such that a reduced output signal to jack sockets 136 leads to a reduced shunting effect of diode 109 thereby increasing the signal strength, and similarly an increased output signal increases the shunting effect of diode 109 thus stabilising the signal output.
