Title: Organosilicon compositions
IPC: C08K5/01
Filed: 1965-11-18
Abstract: A curable composition comprises the following ingredients in the proportions stated: (a) 10 equivalents of RHSiO present as a liquid siloxane consisting essentially of siloxane units in the unit ratio of 10 units of RHSiO to from 0 to 300 units of R2SiO, where R is a monovalent hydrocarbon radical free from aliphatic unsaturation, there being an average of at least 10 units of RHSiO per molecule; (b) from 7 to 10.9 equivalents of a liquid alpha olefin; (c) from 0.04 to 2 equivalents of a liquid alpha, omega-diolefin; and (d) a catalytic amount of Pt, the total equivalents of terminal olefin groups present being within 10% of the equivalents of the RHSiO units present.  The composition on heating to a temperature of 90 DEG  to 170 DEG  C. cures to a solid material (resin, rubber or gel) that is insoluble in organic solvents, though curing can be effected at room temperature. Ingredients specified are (b) hexene-1, decene-1, 2 - ethylhexene - 1, styrene, octadecene - 1 and methylstyrene; and (c) octadiene-1,7, 2-ethylhexadiene - 1,5, decadiene - 1,9, octadecadiene - 1,17 and divinylbenzene.  In a typical example (1) H2PtCl6 was added to a mixture of a trimethylsiloxy-terminated methylhydrogenpolysiloxan and a mixture of liquid alpha-olefins of 9 to 11 C atoms per molecule, 4% by weight of the olefin mixture being alpha-omega diolefins, and the resulting composition was heated to yield a soft gel.  Uses: for sealing and for potting electronic components.

Filed: 1975-12-02
Abstract: 1521130 Selective electro-plating, etching or electro-machining STANDARD TELEPHONES & CABLES Ltd 30 Nov 1976 [2 Dec 1975]  49405/75 Heading C7B Conductive workpieces are selectively electroplated e.g. connector parts mounted on a moving band, by at least partially immersing cathodically connected workpieces in a plating bath e.g. Ni and Au plating tanks, whilst selectively subjecting immersed portions of the workpieces to ultrasonic radiation of a wavelength shorter than the shortest dimension of the irradiated portions so that no cavitation of electrolyte is produced. The ultrasonic radiation may be generated from a lead zirconate/ titanate Piezo-electric transducer driven from an oscillator via an RF amplifier, the transducer resonating at the oscillator frequency; a polymethyl methacrylate lens may be mounted in front of the transducer. The process is also applicable to selective electro-machining and etching e.g. for producing Cu printed circuit board.

Abstract: 1,157,333. Heat exchangers. FORD MOTOR CO. Ltd. 4 Nov., 1966 [21 Dec., 1965], No. 49447/66. Headings F4K and F4S. A heat sink 12 (or 12<SP>1</SP>, Fig. 5) is disposed in the path of a hot fluid passing to a heat exchanger 10 (or 10<SP>1</SP>), the fluid being initially and temporarily at a high temperature and subsequently at a lower (steady state) temperature. The arrangement is intended for use with plant such as gas turbine plant wherein the initial temperature of the hot turbine exhaust gas when the plant is started up is inordinately high and would cause an undesirable temperature differential in the heat exchanger. The heat sink absorbs some of the initial heat and acts to quickly reduce the temperature differential to that of the steady state operation of the heat exchanger. In the preferred form, the heat sink comprises honeycomb passages formed by corrugated members 56 secured between thin sheet stock 58. The heat exchanger, in which air is heated by the hot gases, may be a rotary matrix type regenerator (Fig. 5) or as shown it may be a recuperator in which the fluid passages are formed by plates 18 spaced apart by corrugated elements 16 in the air passages and 14 in the gas passages, the latter passages being of larger crosssectional area than the air passages.

Abstract: 1532786 Measuring ignition timing REGIE NATIONALE DES USINES RENAULT 8 Dec 1975 [10 Dec 1974] 50310/75 Heading GIU [Also in Division H3] In an ignition timing system of the type in which sparking plug pulses from a pick-up 111, Fig. 2 attached to the plug lead of a cylinder under examination, and top-dead centre pulses from a pick-up 101, alternately turn on and off a bistable trigger 21, to produce a pulse train whose markspace ratio, which is displayed on a meter 24, represents the timing of the sparking plug pulses with respect to top-dead centre, in order to compensate for variations in the level of background noise in the signal from the top-dead centre pick-up 101 resulting from variations in engine speed and irregularities in flywheels, the signal from the pickup is transmitted to the trigger via a coupling capacitor 108, a lead 13, a variable attenuator 15 in the form of a variable potential divider 105, T6, and a threshold circuit 16, 17, the variable attenuator being controlled by the average dc level of the signal from the pick-up, this being extracted by an amplifier 18 and a lowpass filter 19. Thus, in effect the signals from the pick-up 101 are so attenuated that their background noise is maintained constant, and then only those peaks that extend above the noise are transmitted to the trigger 21 by the threshold circuit 16, 17.

Abstract: 1494327 Data processing COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 3 Dec 1974 [4 Dec 1973] 52305/74 Heading G4A A data processing arrangement includes an arithmetic and logic unit arranged in response to an op-code to process two multi-byte words, one of which is fed through a field selecting and shifting circuit where a specified field of bits from the multi-byte input word is shifted by a specified amount. As described a two, eight-bit-byte word read from a store MA, addressed by code KAR, is fed to bit inputs a1-a16 of a shifting circuit SC, Fig. 2 (not shown). The circuit is responsive to a shift code kk, a rank code rr and a field length zz, is to select a field of bits from the input word and to right or left justify the field. The circuit has two parts, the first of which (M1) includes gates (1-16) arranged selectively to swap the two bytes in response to the state of the shift and rank codes, Fig. 3 (not shown). The second part (M2) includes gates 1-16, each consisting of eight gates selectively enabled by control signals derived from the rank and field length codes to shift the outputs received from the first part so as to produce the required field of bits in the required position. The circuit also produces a set of mask bits m which may indicate those bit positions of the output of the circuit which are not carrying a significant output due to the field selection and shifting. It is stated that the shift code may, instead of being a single bit indicating right or left justification, indicate a shift of a specified number of bit positions. The output of the circuit SC is fed to an arithemtic and logic unit #B where it is combined with a further word B in response to an op-code K#B. The resulting field of bits, it being stated that the logic circuit #B does not produce carries beyond the field of bits selected by circuit SC, is fed via the word output of unit #B to a shift network TS where, in response to control signals KTS, it is gated to an output unshifted or shifted one bit to the left or right. Circuit TS is also arranged to gate part of a further word, e.g. the word B, to the outputs under control of the masking bits m to fill in those bit positions which do not contain a significant output.
