Title: Improvements in or relating to evacuated discharge tube and like windows
Inventor: SLARK NORMAN ARTHUR
IPC: H01J9/26
Filed: 1962-10-01
Abstract: <PICT:1026805/C1/1> A window for an evacuated tube has the transparent member 2 mounted across an aperture in a supporting structure 1 by means of a thin silver member 3 having a flexible portion 3C between two side portions 3A, 3B, one of which 3A is joined by a silver chloride seal on one side to the window 2 and the other of which, 3B, is joined on the other side to the support 1. The support 1 thus carries the member 2 when it rests upon the support at 3A, but the flexible portion 3C allows for different thermal expansion of the window and support. The window may be a light-permeable window in a cathode-ray tube, or the output window of e.g. a magnetron.

Title: Synthetic Filaments having a Rough Texture on their Surfaces and process for the production thereof
IPC: D01D10/04
Filed: 1968-08-02
Abstract: 1,199,385. Synthetic filaments having a rough surface. TEIJIN Ltd. 2 Aug., 1968 [2 Aug., 1967; 21 Aug., 1967 (2); 23 May, 1968], No. 37046/68. Heading B5B. Filaments having a rough surface are produced by drawing a substantially undrawn length of filament composed of a crystallizable synthetic organic polymer, the length of the filament consisting of an amorphous core and a crystalline skin or, alternatively, the filament consisting initially of drawn and undrawn portions alternating along its length, the undrawn portions consisting of an amorphous core and a crystalline skin. The amorphous core and crystallized skin microstructure may be imparted to an amorphous undrawn filament prior to the drawing step by applying to the filament a crystallization-promoting agent for a time and at a temperature such that only the skin of the filament is caused to crystallize, the core of the filament remaining amorphous. As soon as a crystallized skin of the required thickness has been formed, the agent is removed from the filament. During the application and removal of the agent, drawing of the filament is avoided, and after the removal of the agent the filament is drawn. The difference in density between the core and the skin of the undrawn filament may be at least 0À025 g./c.c. and the thickness of the skin, as measured by means of a polarizing microscope, may be from 0À3 micron to 30% of the radius of the cross-section of the filament. In the case of filaments which have been "semidrawn", i.e. amorphous filaments which have been drawn under such conditions that the filament is converted into a condition where it consists of drawn and undrawn portions alternating along its length, the above conditions of density and skin thickness may apply to the undrawn portions of the filament. The filament may be composed of a polyester, a polyamide or a polypropylene; polyester filaments being preferred because they retain their amorphous character when stored. Suitable crystallization promoting agents for polyesters include benzyl alcohol, aldehyde or amine; anisole; chloro-or nitro-benzene; phenol, cresol, dioxane, acetone, methyl ethyl ketone, dimethyl formamide, dichloromethane, chloroform and methyl acetate. They may be used neat, but are preferably applied as solutions in water or alcohol or as emulsions in water. Examples of suitable agents for polyamides are methylamine, methylenediamine, benzaldehyde, benzyl alcohol, benzylamine, anisole, chloro- and nitrobenzene, phenol and cresol. Suitable agents for polypropylene are decalin, tetralin and toluene.

Title: Improvements in or relating to distilling and coking mixtures of solid carbonaceous materials and hydrocarbon oils
IPC: C10B55/02
Filed: 1934-12-31
Abstract: In the distillation of coal/oil mixtures to obtain oils of low boiling point and coke, the coal/oil mixture is first preconditioned by heating it under complete refluxing conditions to 325 DEG  C., and the mixture thus obtained is then heated rapidly under non-refluxing conditions to 600 DEG  C., the vapours evolved being removed substantially at their speed of formation.  The first stage is carried out in a <PICT:0449619/III/1> retort 13 to which oil is fed from a tank 12 and finely divided coal peat, shale, &c. through a hatch 19, and which is provided with a reflux condenser 14 and a stirrer and mixer 15, 16.  The preconditioned charge is then fed to a retort 1 where it is distilled to dryness, the vapours evolved being fractionated in a column 3 in which fractions boiling at 200, 150 and 100 DEG  C. are collected from plates 5, 6, 7 while vapours and gases pass off to a trap 8 from which condensate is refluxed to the plate 7.  The products boiling above 200 DEG  C. are collected in a still 4 and pumped to the storage tank 12 where they are maintained at 275 DEG  C. A charge of carrier oil is provided as required by distilling coal in the retort 1 and collecting the condensate in the still 4 from which it is pumped to the tank 12.  The first stage may be conducted in an atmosphere of inert gas and the gases evolved may be led to the fractionating column to reduce the vapour pressure of the vapours from the second stage.  A small proportion of coke is preferably added to the charge.

Title: Blood pumping
IPC: A61M60/851
Filed: 1972-08-16
Abstract: 1413801 Extracorporeal blood pumps BENTLEY LABORATORIES INC 16 Aug 1972 [16 Aug 1971] 38293/72 Heading A5R [Also in Division F1]. A pump for extracorporeal blood pumping comprises a disposable flexible envelope 20, Fig. 1, e.g. of polyurethane, with inlet and outlet lip valves 42, 41, and a diaphragm 33 which is reciprocated by a pneumatic or hydraulic actuator 16 to compress the envelope 20 to discharge its contents and to release the envelope to permit refilling by venous blood under its own pressure. The initiation of the discharge stroke is controlled either by a sensor 89 detecting filling of the envelope 20, or by a timer. The pump also may be controlled by the R wave of the patient's ECG waveform. The upper limit of the discharge stroke is determined by closure of an aperture 75 by a projection 77, thereby creating back pressure in an air tube 73 to provide a signal in a pneumatic circuit for reversing actuator 16. The diaphragm stroke is adjusted by rotating a sleeve 56 by a gear train, Fig. 3 (not shown), sleeve 56 being threaded on a sleeve 50 fixed to actuating shaft 43, and having a stop 57 engaging an O-ring 59 at the end of the downward stroke. The diaphragm may be manually actuated by mounting a crank assembly in bushes 78, 79 and engaging an eccentric in recess 83. The envelope and valve assembly is held in place by a cover 29 secured by a releasable clamp, Fig 2 (not shown). The envelope 20 comprises a tube 105, Fig. 4, clamped at each end to inlet and outlet valve assemblies 101, 106 each comprising a lip valve 103, 108, e.g. moulded from silicone rubber, the valve being provided with a slit by cutting first in an axial direction and then intersecting the first cut by a transverse cut, thereby forming clean, sharp edges on the valving surfaces 152. The inlet and outlet fittings 100, 110 and the valves are of substantially constant flow cross-sectional area. The valve width is several times greater than its height. The fittings 100, 110, e.g. of polycarbonate, each comprise a cylindrical portion 115 and a tapered portion 118, and are clamped to tube 105 by metal clamps 135, 136 and 172, 173.

Title: Temperature stabilisation of transistor voltage regulators
IPC: H02J7/14
Filed: 1969-07-31
Abstract: 1,202,349. Automatic voltage control. GENERAL MOTORS CORP. July 31, 1969 [Sept. 24, 1968], No.38390/69. Heading G3R. A voltage regulator generally similar to that described in Specification 1,174,875 is provided with a thermistor 64 which ensures the correct switching action of the transistor 56 over the operating range of ambient temperature to which the regulator is subjected. At high temperatures the resistance of thermistor 64 decreases to shunt away the base current of transistor 56 and so maintain its non-conductive condition in circumstances when, due to increasing temperature, the voltage required to break down the forward biased diode 71 and the base emitter diode of transistor 56 is decreasing faster than the decreasing voltage across the collector-emitter circuit of the driver transistor 66. At low temperatures the thermistor functions to provide a high base drive current for the thransistor 56. The voltage protection circuit comprising members 98, 100, 102, 104, 106 functions to maintain the regulated voltage at a higher value than normal, in the event of a disconnection between the leads 42, 44 or 22, 24. In a modification, Fig.3 (not shown) the diode 71 is replaced by a transistor (110) whose base is connected through a resistor to the conductor 42. Thus when the latter becomes disconnected from 44, the forward biasing of the transistor (110) (from the battery 26) is removed and it becomes non-conductive to permanently switch off the transistor 56 and so reduce the generator output voltage to zero. The driver and output stages of the regulator can be fabricated as monolithie chips Fig. 2 (not shown) which are mounted, together with the thermistor 64, on a ceramic substrate. The latter can be placed in a support mounted within the end frame of the alternator 10.

Title: Improvements in or relating to methods of and means for positioning in-soles in relation to lasts
IPC: A43D3/02
Filed: 1928-12-31
Abstract: 327,182. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Dec. 31, 1928. Pulling-over; lasts.-Prior to a pulling-over or other operation, the insole is jigged on the last by a device portable with the last and adapted to cooperate with positioning surfaces provided on the bottom of the last.. The device is removed prior to a subsequent operation so that the positioning surfaces may be used in positioning the work for the subsequent operation. The device may comprise a strip 18 of steel having, riveted to its ends, pegs 20 adapted to engage holes in the insole and bushed holes in the last a. The holes in the last are spaced laterally across the forward part, and sufficiently inward of the edge to allow of the overlaying of the edge of the upper. The strip 18 is normally curved longitudinally, so that the pegs 20 bind in the holes, and the strip has bevelled edges so that a tool may be inserted between the strip and the insole to prise the device from its position. In a modification, the device is stamped from a metal blank the ends 38, Fig. 8, being bent downwardly to form the positioning projections. These projections are curved laterally, the curves merging into the upper face of the blank to stiffen the angles. The body portion 36 is bowed as in the first example, so that pressure on its centre spreads the legs to enter the holes, and the distortion of the device causes the legs to bind in the holes. Specifications 230,433 and 252,252 are referred to.
