Title: Improvements in television receivers
IPC: H04N5/53
Filed: 1946-03-12
Abstract: 609,755. Television receivers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 12, 1946, No. 7775. Convention date, March 12, 1945. [Class 40 (iii)] [Also in Group XL (c)] In a television receiver in which automatic gain control is obtained by peak rectification of the synchronising impulses a limiter is utilised to prevent noise impulses from affecting the gain control. The detector is direct-coupled to the video amplifier 36 over the limiter 34. The output of the amplifier 36 is direct-coupled to the cathode of a valve 64 over a resistance 60 which reduces the capacity loading on the amplifier anode circuit. The cathode and grid of the valve 64 provide a peak-rectifying diode having a load circuit 68, 70 to which a negative delay potential is applied via a resistance 76 and glow-discharge tube 74. The gain control potential is obtained over a filter 72, 80. The valve 64 also forms the separator for synchronising impulses, which appear in the anode circuit and are clipped and amplified in a subsequent stage 93. Reference has been directed by the Comptroller to Specification 613,026, [Group XL (c)].
Patent GB-1568456-A (GB)
Title: Impact fuse device
IPC: F42C1/02
Filed: 1978-02-28
Abstract: In the case of known impact fuzes, the opening at the end of the fuze housing (1) is closed for the purpose of sealing against moisture during storage and water penetration in flight. In order to simplify the production and in order to improve the response sensitivity, the fuze housing (1), with a cylindrical recess (2) for the axially displaceable impact plunger (3), is closed by an end wall (6). This end wall (6) is integrally connected to the fuze housing (1) and has a nose part (8) which is connected to the fuze housing (1) via a ring (7) of reduced wall thickness (t). This ring (7) forms a weak point for the nose part (8) and can be dimensioned in accordance with the required response sensitivity. <IMAGE>

Title: Measuring the estrogen content of a liquid
IPC: G01N33/74
Filed: 1976-02-27
Abstract: 1497652 Oestrogen determination H YEE 27 Feb 1976 [15 Aug 1975] 07820/76 Heading GIB The oestrogen steroid concentration of a liquid, e.g. wine, is determined by first separating the steroids from the liquid, then hydrolyzing the separated steroids, extracting the hydrolyzed steroids from the hydrosylate, reacting the hydrolyzed steroid extract with a chromogen forming reagent and evaluating the steroidal concentration by spectrophotometric measurement of the chromogens. Separation can be effected (a) by ammonium sulphate precipitation and centrifuging or solvent extracting or (b) by chromatography. Hydrolysis of the separated steroids may be by treatment with an enzyme mixture of #-glucaronidaze and phenol sulphataze. Chromogen formation may be accomplished by reaction of the steroid extract by coupling of its phenolic groups with a conjugating agent and then oxidizing; 4-aminoantipyrine or 3-methyl-2-benzothiazolinone hydrazone hydrochloride can be used as the conjugating agent and ferric or ceric salts as the oxidants.

Filed: 1952-03-27
Abstract: 781,442. Flame traps. HIBBERD & CO., Ltd., F. C., and POTTS, G. E. Nov. 27, 1953 [March 27, 1952], No. 7881/52. Class 7(2) [Also in Group XXIX] A metal casing 1 is divided by a vertical partition 2 into substantially equal compartments 3, 4 in communication with each other by way of an aperture 5 in the partition, exhaust gases passing through the aperture being deflected downwardly by a baffle 6. There is an inlet 14 for the gases in a vertical wall of the compartment 3 and a gas outlet 16 near the top of a vertical wall of the compartment 4, and each compartment contains a coolant liquid such as water maintained at a predetermined level 7 when the flame trap is in use. As shown, the gases are introduced into the compartment 3 through a distributer pipe 12, Fig. 3 of rectangular crosssection and adapted to be inserted into that compartment through a hand-hole 13 situated opposite the inlet 14; longitudinal slots 15 in the lower wall of the pipe allow the gases to pass downwardly to impinge on the surface of the water in the compartment before passing through the aperture 5 to an outlet grille and the outlet 16. The flame trap is supplied automatically or manually with water fed from a tank mounted above the casing 1 and fitted with a combined filler cock and discharge valve (Fig. 6, not shown). The trap incorporates a safety device as described in Specification 781,441 [Group XXVI] for automatically cutting off the fuel supply to an I.C. engine in the event of untoward rise in temperature conditions prevailing within the trap, and a valve is associated with the pipe 12 to prevent water passing from the trap to the exhaust pipe of the engine.

Abstract: 915,134. Toothed gearing. MACKIE & SONS Ltd., JAMES. March 10, 1961 [March 10, 1960], No. 8490/60. Class 80 (1). [Also in Group IX] A winding-machine of the kind in which yarn is traversed by a rotating scroll 20, Fig. 1, to cross wind the yarn on to a rotating spindle 10, is characterized by gearing that interconnects the scroll 20 and the spindle 10 such that the relative angularity of the spindle and the rotary traverse member can be varied in order to wind a parallel package, or a package having a predetermined conicity, without bringing any of the gears out of mesh. In Fig. 1 the spindle 10 is driven by a spiral gear 26 in a movable part 44 of the frame meshing with a spiral gear 28 in a stationary part of the frame. By temporarily slacking some bolts 46 the setting of the movable part 44 can be adjusted to vary the inclination of the spindle 10 without disengaging the gears 26, 28. The spiral gears could be replaced by bevel gears. As the package 16 increases in diameter the scroll 20 moves away from the spindle 10 by pivoting about an axis A-A. A spiral gear 30 dips into an oil bath to transfer oil to the spiral gears 26 and 28. In a modified construction, Fig. 4, the spindle 10 of the yarn package 16 is fixed in position but the scroll 20 is supported by a bracket 62 that can be locked in any desired setting about an axis 58. The axis of the scroll 20 and that of the spindle 10 may thus be parallel or at an angle to each other. The axis 58 comprises a spindle carrying spiral gears 55, 56 that mesh with spiral gears 54, 57 driving the spindle 10 and the scroll 20, respectively. The spiral gears 54, 55, 56, 57 may be replaced by bevel gears. As the yarn package 16 increases in size the scroll 20 moves away from the spindle 10 by pivoting about an axis A. Specification 910,842 is referred to.
