Title: Improvements in or relating to radar pulse length discriminator circuits
Inventor: DAY FRANK EDWARD GILBERT
IPC: G01S7/292
Filed: 1968-05-15
Abstract: 1,212,265. Radar pulse discriminators. MINISTER OF TECHNOLOGY. 6 May, 1969 [15 May, 1968], No. 22983/68. Heading H4D. In a discriminator (Fig. 1) for separating wanted radar echo pulses from unwanted longer pulses, the radar video channel excites a pulsator circuit 1 generating reciprocal differentiated pulses from the leading and trailing edges of the unwanted and wanted pulses respectively; a delay circuit being triggered on a negative pulse to generate an output pulse of target echo form and preset duration, whose trailing edges triggers a monostable to produce a delayed target pulse. A further monostable is triggered direct by a negative-going pulse of the reciprocal waveform to produce a target pulse, and the monostable outputs are applied to a coincidence gate, whose output develops a target echo pulse of width equivalent to the delay at 2; such output pulse (Fig. 2, not shown) not being produced by input pulses exceeding a target echo pulse in duration (e.g. from precipitation) but an output pulse being produced by an input pulse of target echo duration, whether or not superimposed on a signal of longer duration.

Filed: 1963-06-11
Abstract: 971,450. Hydraulic pit props. MASTABAR MINING EQUIPMENT CO. Ltd. June 11, 1963, No. 23158/63. Heading E1E. In an hydraulic pit prop having a two-stage pump 32, 36 and a setting valve 42, 44, 52, the member 42 has a restricted clearance therearound as shown whereby the valve bore 40 is filled with trapped fluid when the valve is first put into service. The valving arrangement is such that when the members 42, 44 are abruptly lifted against the action of a spring 40 due to the build up of pressure in the chamber 18, a back pressure impulse is set up to assist the return spring to move the ball valve 42 against its seating 52 whereby a distinct click is communicated to the operator and also felt through the pump operating handle connected to the pump piston rod 38. Excessive movement of the pump handle depresses the piston rod 38 to operate a release valve 53, 54 and then to separate the ram parts 20, 24 to permit a free return of fluid to the pump reservoir.
Patent GB-737235-A (GB)
Title: Method of carrying out polymerisation reactions
IPC: C08G77/06
Filed: 1953-08-21
Abstract: Polymerization reactions are carried out by including polymerizable monomeric organic substances in canal-formers and then reacting together the monomeric substances to form a linear polymer. Canal-formers are substances the molecules of which have canal-like cavities, or can be made to have such cavities, e.g. urea, thiourea, desoxycholic acid and dinitro diphenyl. Specified polymerizable substances are 2,3-dimethylbutadiene-1,3, styrene, butadiene, a mixture of 2,3-dimethyl butadiene-1,3 and styrene, cyclo-hexadiene-1,3, cyclopentadiene, dicyclopentadiene, 2-chloro-butadiene, cyclooctatetraene, vinyl chloride, tetramethyldihydroxydisiloxane, and trihydroxydisiloxane. Cross-linked products may be prepared by polymerizing compounds having functional groups which do not react in the canal-former but can be made to do so after removal therefrom.  Thus a ,o  - silanols having another hydroxyl group in the middle position are polymerized in a canal-former, the canal-former removed, and the middle hydroxyl groups of the separate macromolecules condensed together.  The polymerization may take place under pressure or at raised temperature provided that the temperature is lower than that required for appreciable dissociation. Pressure may be applied by heating in a sealed vessel or through pressure-transmitting media, e.g. mercury, in a press.  The canal-former may be present in such amount as to include the entire reactable compound or in excess of this amount, and may be removed after the polymerization when, in the case where excess was used, a porous polymer remains.  When the canal-former is being removed it is preferred to add simultaneously emulsions or dispersions of substances for the further working-up of, or further reaction with, the polymer, the continuous phases of such emulsions or dispersions being solvents for the canal-former only.

Filed: 1933-08-24
Abstract: 424,890. Photographic contact printing-apparatus. MASON, B., Octo, Seaview Avenue, West Mersea, and MASON & SONS, Ltd., E. N., Arclight Works, Colchester. Aug. 24, 1933, No. 23530. [Class 98 (ii)] The apparatus has one or more arc lamps supported by a carriage which moves to and fro transversely to the printing paper and is caused to stop for a predetermined period at the ends of the travel in order fully to expose the edges of the paper. As shown, arc lamps 1, 2 are supported by a carriage 5 ona a track 4, and an electric motor 10 drives through reduction gearing a crank or disc 15 with a roller 17 which engages with a slot to produce a uniform to and fro motion of the carriage. The slot is formed in a cross-head 18 secured to the machine frame, and comprises straight portions 19, 20 joined by curved portions 21, 22 which have a radius of curvature equal to the length of the rotating crank. The roller is guided into each curved portion successively by gates 23, 24 which are connected by pivoted links 26, 27, 29, 30, 31, 32, 34. The bell-crank links 27 32 are pivoted to the framework at 28, 33 respectively, and have extensions 35, 36 in position across the slots 19, 20 such that when the roller engages them the gates are moved into the position to guide the roller on its return movement into the appropriate curved portion 21 or 22. The carriage is brought to rest smoothly by a brake device consisting of a spring-actuated shoe 38 engaging a curved blade 37 of steel. In a modification, the motion of the lamp carriage is produced by a rotating pinion which engages with an endless rack movable in a transverse direction. The straight portions at the ends determine the period of stopping of the lamps. In another modification, the carriage is moved backwards and forwards by a screw spindle with left and right-hand threads, and at the ends the pitch of the threads is reduced. The member engaging the screw threads is returned into engagement at the ends by a rotating cam which determines the period of delay. Means for obtaining a variable speed reduction comprise two sets of sprockets, one rigidly mounted, and the other 62 (Fig. 10) loosely mounted, on a hollow shaft 60 provided with a slot 61. A rotating shaft 64, which can be slid along by a forked lever 68 mounted on a collar 67, can engage by means of a spring-pressed dog clutch 66 any of the sprockets 62. Circulation of oil in the apparatus is ensured by a pump 72 and branch pipes 75.

Filed: 1920-08-11
Abstract: 158,858. Griscom-Russell Co., (Assignees of Price, J.). Feb. 9, 1920, [Convention date]. Fluid-actuated valves.-In evaporators, especially such as are used for distilling sea water, in which the liquid level is maintained constant by a float valve or the like, the rate at which the concentrated liquid is discharged is regulated by the rate of flow of the incoming liquid, so that the concentration reached is kept approximately constant. For this purpose the incoming and issuing liquids are passed through restricted orifices 10, 19 of the Venturi type. The throats of the Venturi tubes are connected to the upper and under portions respectively of chambers 11, 14 containing diaphragms 11<a>, 15 while the wide portions of the conduits are connected by pipes 12<a>, 16a to the under and upper portions of the same chambers. The diaphragms 11<a>, 15 are connected by a rod 13, the motion of which operates through linkages an equilibrium valve 21 controlling the discharges from the evaporator. The relation between the rates of flow, and the resulting concentration, can be regulated by a needle valve 26 in the Venturi tube 10. In a modification, only one diaphragm is employed, the throats of the two Venturi tubes being connected to the spaces above and below it. Reference has been directed by the Comptroller to Specification 156,501, [Class 86, Mixing &c.].
