Title: Improvements relating to band clips
Inventor: MASON GEORGE FREDERICK
IPC: F16L33/04
Filed: 1963-11-01
Abstract: 1,013,352. Band clips. CALDMORE TOOLS Ltd. Oct. 28, 1964 [Nov. 1, 1963], No. 43122/63. Heading E2B. A band clip comprises in combination a pair of abutments 10, 11 a band 12 interconnecting the abutments, the band and the abutments being moulded integrally with each other from a synthetic resin material and the band being stretched without breakage beyond the yield point after moulding, and adjusting means 15 operative upon said abutments. The stretching of the band beyond the yield point ensures that when in use there is little or no stretching of the band until the yield point is reached during tightening after which continued tightening will cause the band to break. In the construction shown the adjusting means is a screw which is engaged with a screw threaded hole in the abutment 10 and the band adjacent the abutment 10 is formed with a V shaped aperture through which the abutment 11 is passed in use to be engaged by the tip of the screw threaded bolt 15. The band as shown is provided with lateral ribs 13 but these can be omitted if desired. In a modification two bands interconnect the abutments.

IPC: B60T13/16
Filed: 1971-09-16
Abstract: 1306304 Wheel brake control systems GENERAL MOTORS CORP 16 Sept 1971 [9 Oct 1970] 43226/71 Heading F2F A vehicle wheel brake control system comprises an open-centre hydraulic booster 11 actuating a master cylinder 10 to supply fluid via a modulator assembly 20 to the wheel brakes; the modulator assembly comprises a valve 54, biased by a spring 44 to allow fluid to flow therethrough and movable by the fluid pressure to interrupt the flow, and a piston 36 subject to fluid flow from a source to the booster such that upon booster actuation, fluid pressure acts on the piston to assist the spring. The bias of the spring 44 is such that it is sufficient to maintain the valve 54 in the open position against master cylinder hydraulic pressure when the booster 11 is inoperative. During normal braking, a modulator control valve 74 allows fluid from a steering pump 62 to pass to both sides of the piston 36 and to the booster 11, the valve 74 being in the position as illustrated. Due to differential piston areas, the booster back-pressure upon actuation produces upward forces on the piston 36. If a wheel-lock situation develops, a electrical signal actuates a solenoid 92 to move rightwardly the valve 74, allowing fluid to pass to a chamber 38 above the piston 36 only, thus closing the valve 54. If pressure build-up in the chamber 38 causes full downward piston movement, subsequently the pressure is relieved by a one-way valve 42 in the piston, so that fluid is continuously supplied to the booster operation. To attain normal braking the electrical signal is removed and the valve 74 takes up its previous position. Fluid is allowed to escape from chamber 38 slowly by a flow control valve 99 to avoid sharp brake actuation.

Title: Process for the extraction and recovery of acid constituents, such as phenols, thiophenols and/or homologues thereof, from non-aqueous mixtures containing them
IPC: C07C37/72
Filed: 1961-12-04
Abstract: Phenol, thiophenol and/or their homologues are extracted from non-aqueous mixtures containing them, using an aqueous solution of an alkali metal salt of benzoic acid, preferably sodium benzoate, as the extraction agent.  The extraction agent may also contain another salt of a relatively strong base with a relatively weak acid.  The aqueous extract obtained is washed with an aliphatic hydrocarbon to free it from traces of non-phenolic substances, and then the phenol, thiophenol and/or their homologues are extracted from it, using a branched chain alcohol with a boiling point above 230 DEG C. as the extraction agent.  The solution of phenol, thiophenol and/or their homologues thus obtained is then fractionally distilled to retrieve the phenolic products.  The aliphatic hydrocarbon used is preferably a benzine fraction free from aromatic substances.  The branched chain alcohols specified are those containing at the most 20 carbon atoms and which are prepared by the "oxo"-synthesis, such as 2:3:4:7-tetramethyl-nonanol-(9) or 2:2:4:8:10:10-hexamethyl-7-methylol-undecane.  One example is given which compares the relative extraction efficiencies of aqueous sodium benzoate and sodium phenolate solution when each of them is used to extract phenolic substances from a "carbolated oil" at 70 DEG C.

Abstract: 1281207 Converting RCA CORPORATION 10 Sept 1969 [20 Sept 1968] 44610/69 Heading H2F [Also in Divisions H1 and H4] In a colour television receiver using a tube with superimposed layers of different coloured phosphors which are excited according to the energy of the beam from a single electron gun, a staircase colour switching waveform is applied to the screen and an inverse staircase waveform is applied to a grid adjacent the screen to correct raster errors which would otherwise arise to the varying velocity of the beam. In Fig. 2 the V+ supply is connected through a protective relay 50 to the primary winding of a saturable transformer 57, and a circuit is completed when SCR 58 is triggered by a pulse applied through transformer 61. The capacitor 68 is then charged to the maximum level B from the transformer; SCR 58 turns off as the current decreases, and the capacitor 68 discharges through transformer 57 for one line duration (53 microseconds) when the transformer saturates. The transformer and capacitor resonate and the charge on the capacitor reverses, whereupon the transformer desaturates for a further line duration to produce the minimum level R. At the end of this period the SCR 62 is fired by a pulse applied through transformer 65 so that the charge on capacitor 68 can be transferred through transformer 57 to capacitor 64 and dissipated in resistance 63, resulting in the intermediate output level G. The output voltage on capacitor 68 is combined positively and negatively with an EHT voltage derived from a deflection circuit and supplied through resistance 69, to provide the two complementary staircase waveforms shown at opposite ends of the transformer winding.
