Patent GB-1018970-A (GB)
Title: New copolymers and articles
Inventor: CLARK KEITH JASPER
IPC: C08F210/00
Filed: 1963-09-16
Abstract: A transparent copolymer of 5,5-dimethyl-hexene-1 with a minor amount of a linear 1-olefine having from 4 to 18 carbon atoms is made by copolymerizing a mixture of the monomers in the presence of a catalyst which under the polymerization conditions will polymerize propylene to a polymer which is at least 70% insoluble in boiling heptane, and deashing the obtained copolymer using a dry reagent to reduce the ash content of the polymer to less than 0.1% by weight. The copolymer may be random or block.  The copolymerization may be effected in the presence of hydrogen, and in bulk, or in an inert diluent or solvent, such as a petrol fraction boiling between 180 DEG and 220 DEG  C., toluene, or chlorobenzene. The 1-olefine may be butene, pentene, hexene, or heptene.  The de-ashing reagent may be a hydrocarbon miscible alcohol such as isopropanol, butanol, nonanol, isodecanol, an acid such as n-nonoic acid, an amine such as 3,5,5-trimethylhexylamine, or a mixture of an alcohol and a complex-forming carbonyl compound e.g. isopropanol mixed with acetylacetone. The exemplified catalyst is a mixture of Al(C2H5)2Cl and TiCl3 obtained by reducing TiCl4 with aluminium ethyl sesquichloride.

Abstract: 367,927. Testing physical qualities of materials. HOUNSFIELD, L. H., 3, Durrington Park Road, Wimbledon, London. Dec. 3, 1930, No. 36416. [Class 106 (ii).] In apparatus in which the load applied is measured by a spring the deflection of which is indicated by a liquid gauge, means are provided for eliminating air from the gauge system. The load is transmitted to a spring beam 1 the deflection of which moves a spring- pressed plunger 18 to force mercury or other indicating liquid up a tube 21 and into an indicating capillary tube 22, the end of which is open and provided with a screened and perforated cap between which and the tube is a felt washer. The block 19 has screwed into it a barrel in which works a plunger 82 the barrel communicating with the mercury space. The screw 81 is cut away at 85 to allow a free passage of fluid from one side to the other. On raising the plunger the air can escape through a vent 83. Bubbles of air rising to the top when the mercury is lowered can escape through the hole 84. In a modification to obviate mercury spilling through the hole 83, the latter is dispensed with and the plunger made of felt. In further modifications the plunger is solid as in the Figure, and the mercury or indicating liquid may escape either through a vent into an adjoining chamber or into an annular chamber above the plunger. In either case vents are provided from the tops of these chambers to the atmosphere, which vents are closed by felt wads.

Title: Regulated voltage supply circuits
IPC: G05F3/22
Filed: 1973-08-02
Abstract: 1432027 Automatic voltage regulation SONY CORP 2 Aug 1973 [7 Aug 1972] 36771/73 Heading G3X A circuit suitable for fabrication as an integrated circuit supplies an amplifier with a voltage which is independent of input voltage variations and which is compensated for temperature characteristics of the amplifier. As shown, an amplifier 30 is supplied with a regulated voltage derived from a supply V cc  by a network including three pnp transistors and one npn transistor. Transistors 1 and 2 form a constant current source, the regulation of which is improved by feedback through the base-emitter and base-collector circuits of transistors 3 and 4. The constant current produces a constant voltage drop across transistor 3 equivalent to two pn junctions, so that a supply-independent voltage is produced and temperature effects are eliminated if the amplifier 30 has a Darlington form. Different output voltages can be produced by including additional pn junctions between the bases of transistors 3 and 4 or elsewhere in the circuit Figs. 2, 3 (not shown). The output voltage may be taken from an emitter follower stage, Fig. 4 (not shown), and additional diodes or transistors may be included to improve the stabilization, Figs. 5 and 6 (not shown).
