Abstract: 1445879 Rubber filler compositions CHEMISCHE WERKE HULS AG 6 Dec 1973 [9 Dec 1972] 56618/73 Heading C3P A pulverulent rubber mixture containing a filler is produced by adding mixing under pressure a filler with a solution in an organic liquid of a rubber which is polybutadiene or a butadiene-styrene copolymer containing at least 40% by weight of butadiene units and which has 8-50% of vinyl groups produced by homopolymerization of butadiene or copolymerization of butadiene and styrene in the presence of a lithium catalyst and reducing the pressure acting on the flowable mixture thus obtained so that the organic liquid flashes off and a rubber-filler mixture is obtained as a free flowing powder which does not cake together. The solution may contain a plasticizer oil and the filler (e.g. carbon black or silica) may be added to the solution as a solid or as a dispersion in an organic liquid. In the examples butadiene is polymerized alone or copolymerized with styrene in hexane or pentane in the presence of nbutyl lithium and ethylene glycol dimethyl ether or tetrahydrofuran and a dispersion of carbon black or silica in hexane containing in some cases plasticizer oil or sulphur and zinc oxide is mixed under pressure with the rubber solution produced.

Abstract: 1,151,975. Grooving of plastics strip. ETHYLENE-PLASTIQUE S.A. 22 Dec., 1967 [30 Dec., 1966; 8 Sept., 1967; 7 Dec., 1967], No. 58489/67. Heading B5A. In a process of producing a strip of plastics material having improved flexure properties, one or more grooves are formed in it whilst the temperature thereof is from 25-100‹ C. below its crystalline melting point, and the strip is subsequently stretched longitudinally. The strip may be of polyethylene, polypropylene or of polyamides; it may comprise laminates composed of polypropylene and propylene copolymer, in which the latter provides surface layers on a polypropylene core. The grooves may be formed by milling wheels arranged in a plane or round a roller on which the strip is passed. Alternatively, Fig. 5, metal cables 6 on driving rollers 1, 2 are pressed on the strip 4 as it turns on a smooth roller 5 to form the grooves. Instead of cables 6, a number of circumferential ribs are provided on the roller 5 and are forced into the strip surface by a smooth steel strip forced against the strip 4 by the rollers 1, 2.

Abstract: 1,267,750. Film transport. AGFAGEVAERTA.G. Dec.1, 1969 [Nov.30, 1968], No.58517/69. Heading G2A. A camera for roll film having a perforation per picture frame has a feeler finger 3a on a lever 3 which is urged to engage in the said perforation 2a by rotation of the film transport mechanism, and when so engaged the lever 3 blocks the film transport against further movement. As shown, lever 3 pivots on a pin 4, and is clasped by the end of an arm 6 which is supported by a bearing ring coaxial with ratchet wheel 5. Wheel 5 is attached to the take-up spool, and when this is rotated to wind on the film 2 a frictional drive is imparted to arm 6, which urges lever 3 clockwise. When a perforation 2a aligns with feeler 3a, the latter enters. This movement also brings a toothed end 3b of the lever into engagement with the ratchet wheel 5, blocking the film transport. When the camera release 7 is pressed, an oblique surface 7a thereof engages against arm 6, so pivoting lever 3 and lifting feeler 3a out of the perforation and toothed end 3b away from ratchet 5.

Title: Improvements in compandors
IPC: H03G3/00
Filed: 1969-12-04
Abstract: 1,273,168. Compandors. STANDARD TELEPHONES & CABLES Ltd 4 Dec., 1969, No. 59271/69. Heading H4R.  In an expander for use in a LINCOMPEX compandor system in which a pilot signal is transmitted frequency modulated with the degree of L compression applied to a signal at the transmitter to enable restoration of the original signal range at the receiver, gross variations in the expander control signal at the receiver are detected and the amplification is adjusted to a pre-set value during periods of such gross variation. Fig. 1 shows an expander in which speech signals are separated from the incoming signals by a filter 2 and fed to a variable gain circuit 4 whose gain is controlled by a pilot signal derived from the incoming signals by a filter 3. The pilot signal waveform is shaped to provide constant amplitude constant width pulses of frequency equal to the pilot signal frequency to feed to cup and bucket discriminator 6 which produces a control voltage whose value depends on the pilot frequency. The control voltage is applied to one input of a differential amplifier 7 feeding via antilogue circuit 10, the control input of the variable gain speech amplifier 4. The other input of the differential amplifier is provided by a guard voltage. During normal reception of the pilot the guard voltage, derived from the pilot signal before application to the discriminator, is such as to allow normal operation of the differential amplifier to pass control signals to the amplifier 4. If however the pilot signal is interrupted the differential amplifier is inhibited and the resulting change in output signal causes, via the suppressor circuit 9, the control signal applied to the gain controlled amplifier to be adjusted to produce mid range amplification in amplifier 4. The suppressor circuit may be a trigger circuit actuated by a control voltage exceeding a predetermined value to connect the control line to a standard potential point, Fig. 2 (not shown), or a simple transistor connected to be switched on by an excess voltage at its base to connect the control line to a standard potential, Fig. 3 (not shown).
