Title: Improvements in or relating to tool holders
IPC: B23B29/24
Filed: 1946-11-25
Abstract: 619,186. Turning. HAASTEREN, J. M. VAN. Nov. 25, 1946, No. 34971. Convention date, April 18. [Class 83 (iii)] A tool-holder for use with a lathe has a releasable carrier mounted by means of a dovetail connection on a triangularly-shaped support, a dovetail-shaped groove being of such width as to fit over an entire side of the support. The latter 1 is rotatably adjustable and clamped in position by a nut 4 to the usual tool-slide. The tool-carrier 5 is adjustable for height by a set-screw 8 and is clamped against the post by a wedge-piece 10 which has a cylindrical seating on the side of the post not used for the carrier. Two nuts 13, 13<SP>1</SP> are used for clamping, the first is lightly clamped and the latter fully tightened to effect the wedging when the toolcarrier is arranged as shown, but, when occupying the broken line position on the other side of the post, the nuts are operated in the opposite manner.

Title: A device for increasing the pressure of a fluid working medium
IPC: F04B53/14
Filed: 1965-08-17
Abstract: 1,120,261. Compressors. L. G. FORTINOV. Aug. 17, 1965, No.35160/65. Heading F1N. A compressor comprises a two diameter plunger 2, 6 reciprocable in a casing 1 by compressed gas continuously supplied from a source or sources to inlet ports J, E in the casing, so that the gas entering through the inlet port E is increased in pressure by movement of the plunger 2, 6 and is discharged through an outlet valve 4. The compressed gas supplied to the ports J, E enters a chamber I to act on the small diameter end 2 of the plunger and a chamber II to act on the large diameter end 6 of the plunger. The chamber II has an outlet port H closable by a plunger valve 9 urged towards the open position by a spring 10 disposed within the plunger. When the outlet port H is closed by the valve 9, pressure in the chamber II causes the plunger to perform a compression stroke. The valve 9 remains closed during the compression stroke, despite the action of the spring 10, due to the pressure in the chamber II. At the end of the compression stroke the valve 9 is opened by the contact between a projection 7 on the plunger and a shoulder 11 on the valve so that the inlet port J closes and gas in the chamber II passes out through the port H for possible use as a cooling fluid for the compressor. A fresh charge of compressed gas enters the chamber I to return the plunger and thus cause the valve 9 to close the port H and open the port J whereafter the cycle is repeated.

Patent GB-430422-A (GB)
Title: Improvements in and relating to the manufacture of rubber
IPC: C08C1/14
Filed: 1933-12-14
Abstract: Soft rubber is obtained from the latex of Hevea brasiliensis by a process which consists in adding a small amount of an alkali to the latex, followed by sufficient acid to effect coagulation.  The wet coagulum is then heated in air at a temperature above 70 DEG  C. but not materially above 100 DEG  C. until dry, and until the required degree of softness is obtained.  The alkali which is added may consist of either caustic soda, caustic potash or ammonia.  It is essential that the alkaline latex should be coagulated before the addition of any compounding ingredients.  The coagulating acid may be added at once or after a lapse of one or more days and before coagulation the latex may be diluted, e.g. to approximately 1/4 lb. dry rubber per gallon.  The coagulum may be washed with water, and if desired treated with anti-oxidants.  In an example when employing field latex of approximately 3 1/2 lbs. of dry rubber per gallon, a 10 per cent solution of caustic soda is added to give 1/2 per cent of alkali by weight on the latex.

Title: Improvements in or relating to circuit arrangements for use in a colour television receiver
IPC: H04N9/24
Filed: 1963-09-09
Abstract: 1,026,127. Colour television receivers. PHILIP'S ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 9, 1963 [Sept. 12, 1962], No. 35478/63. Heading H4F. In a colour television receiver circuit comprising a cathode-ray tube 7 the screen of which incorporates (a) strips for producing an indexing signal of frequency fi which is applied to a frequency divider 4, and (b) " run-in " strips for producing a signal of frequency fo which is applied to cause the divider to operate in the correct phase, means are provided for establishing a minimum value of beam current during a line scan, so that in the absence of a video signal there is sufficient current to ensure the continuous operation of the frequency divider, and for producing a value of beam current during at least a part of the " run-in " interval which is substantially higher than said minimum value. Valve 11 forms a part of the frequency divider 4 and during the interval when the divider is operating, i.e. during the interval t 1  to t 2  in Fig. 3, it is biased negatively by rectifiers 13, 14 so that a potential change is produced across anode load 16, 17 as shown in curve c. Valve 19 is biased to cut-off by line flyback pulses and produces a potential change in the same load as shown in curve b. The resulting combined signal is as shown in curve a and is applied to cathode 10 of tube 7 which is otherwise biased so that beam cut-off occurs at level 21. The tube beam is accordingly (1) cut-off during the fly-back interval t 2 -t 3 , (2) established at a predetermined minimum during the line interval t 1 -t 1 , and (3) established at a substantially higher value during the " run-in " interval t 3 -t 1 . The magnitude of the higher value is determined by selection of resistors 16 and 20. In a second embodiment, Fig. 6 (not shown), the signal from valves 11 and 19 is applied through an inverter stage to control a gate stage through which the combined monochrome and chrominance signal is applied to the cathode-ray tube grid. The operation is such that the gate is cut-off during the " run-in " interval and a pulse of appropriate amplitude established in the video signal. The cathode-ray tube is blanked at the cathode by a circuit which establishes the desired minimum value of current during the line interval. A third embodiment, Fig. 4 (not shown) is identical with that shown in Fig. 1 of Specification 1,026,128. Specification 975,622 is referred to in connection with details of the frequency divider. Specification 1,026,126 is referred to in connection delay requirements of the circuit. Reference has been directed by the Comptroller to Specifications 926,183 and 954,941.

Title: Improvements in and relating to apparatus for delivering liquids at a constant mean rate
Inventor: EDEN GEORGE EDWARD
IPC: G21H5/02
Filed: 1957-11-14
Abstract: 856,302. Liquid meters; valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 14, 1958 [Nov. 14, 1957], No. 35516/57. Classes 69 (2) and 135. Apparatus for metering liquid at a controlled mean rate comprises a free piston 12 in a cylinder 11 and a system of valves 13-16 operated at predetermined intervals by timing means to allow liquid from a pressurized source to pass alternately into opposite ends of the cylinder, thus displacing the piston and discharging liquid from the other end of the cylinder. The liquid is supplied to the apparatus from a reservoir 23 which may be pressurized or located high enough to provide sufficient head or a pump 22 may be provided. The valves 13-16 comprise short lengths of polyvinylchloride or other flexible tubing which are nipped in pairs (e.g. the inlet valve 13 to one end of the cylinder and the outlet valve 16 from the other end) by an arm 17 or 18 which is pressed on the tubes by springs 17a or 18a, but can be raised when an electromagnet 19 or 21 is energized. To compensate for slight variations in thickness of the tubes, the arms 17 and 18 are slit to form two prongs or, alternatively, abutments against which the tubes are pressed are made resilient and, to avoid liquid bypassing the cylinder, the valves are arranged so that each pair of valves closes not later than the other pair opens. For timing the valve operation, a clockwork switch may close a contact at regular intervals of, say, half a second and, to vary the intervals, the time switch may operate through a cascade of relays having a selector switch by which intervals of ¢, 1, 2 or 4 seconds may be chosen; alternatively, the time switch may act through a multibank uniselector, a set of stepping relays or an electronic multivibrator. The maximum rate of operation of the valves must not exceed the rate at which the supply pressure can drive the piston so that the piston waits at each end of the cylinder until the valves change over. By providing interchangeable pistons of different lengths, the volume displaced per stroke can be altered. The cylinder may be made of transparent material so that movement of the piston can be checked visually and the piston and cylinders heads are arranged so that the valve ports are sealed at the ends of the piston strokes, the sealing being improved by a resilient ring round the port or in the end of the piston. Where the liquid being metered is radio-active, the reservoir and other parts of the apparatus may be shielded and a switch may be provided for opening all four valves when it is desired to wash out the apparatus.

Abstract: 828,223. Electroluminescent screens. SYLVANIA-THORN COLOUR TELEVISION LABORATORIES Ltd. Feb. 28, 1958 [Nov. 28, 1956], No. 36444/56. Drawings to Specification. Class 39(1). [Also in Group XL(b)] A layer of zinc sulphide activated by copper and lead is disposed between an electron permeable layer-like electrode of aluminium and a light permeable layer-like electrode of stannic oxide so that it may be subjected to the combined effect of an electron beam and an alternating field applied between the electrodes. The resulting luminescence has an intensity determined by the intensity of the beam and the amplitude of the field, and a colour determined by the frequency of the field. In accordance with the invention, the electron beam is caused to scan the layer whilst control means synchronously vary the intensity of the electron beam, the amplitude of the field, or both, and likewise synchronously vary the frequency of the field, or the relative. amplitude of components of the field of different frequency, in such manner that an image of different colours in different areas of the layer is reproduced. The invention is stated to be of general application, television, illuminated signs and advertisements being referred to, but is described only as applied to television receivers [see Group XL(b)]. The receivers reproduce only two colours, green in response to a 50 c/s alternating field and blue in response to a 10,000 c/s alternating field. Reference is made to a rear-viewing cathode-ray tube in which the screen electrode facing the electron beam is permeable to both electrons and light and the other electrode is opaque and reflecting to light.
