Title: Apparatus for monitoring radar systems
IPC: G01S7/40
Filed: 1956-03-02
Abstract: 798,362. Radar. S.A.D.I.R. CARPENTIER. March 2, 1956 [March 18, 1955], No. 6661/56. Class 40 (7). A monitor arrangement for a pulse radar system includes means for tapping off a small fraction of the power being fed to the aerial, delaying it for a period longer than the receiver is disabled, and feeding it to the receiver input to produce an indication on the display. In one embodiment pulse modulator 2 controls the generation of pulses in transmitter oscillator 1 and these are fed over line 3 and directional coupler 11 to antenna 4. An anti-TR arrangement 5 is provided and a TR unit 6 couples the aerial feeder to the receiver 7 which is provided with a cathode-ray tube display unit 8. A small part of the power fed through coupler 11 to the aerial is tapped off and fed over line 12 to gate 13. This gate is controlled by pulse generator 16 coupled through delay network 17 to modulator 2. It is opened for a period commencing at a time delayed after the front edge of the transmitted pulse by less than the pulse length and finishing at the end of the transmitted pulse. Energy passing through the gate 13 is fed to a ceramic delay line 19 having at its far end normally closed gate 20. The pulse from generator 16 is fed to open gate 20 through a conventional delay means 21. The delay introduced by means 21 is the delay period it is desired to give the monitor signal (less the delay at 17) and is an odd multiple of the delay time of line 19. Thus high-frequency energy fed into the line is reflected up and down between the two closed gates until the required delay time is reached. Gate 20 then opens and it is fed along line 15 to coupler 11 and thence to the receiver. If the system is functioning correctly a spot is obtained on an intensity modulated display or, in the case of a P.P.I. display a bright circle round the zero position. A suitable construction for gates 13 and 20 is described with reference to Fig. 2 (not shown). Specification 767,077, [Group XL (b)], is referred to.

Abstract: 774,032. Piston-rings; stuffing-box substitutes. GOETZEWERKE F. GOETZE AKT.- GES. March 9, 1955 [March 11, 1954], No. 6923/55. Classes 122 (1) and 122 (5). A packing - ring, applicable to pistons or stuffing-boxes and constructed of steel, cast-iron, bronze or other non-ferrous material, has a circular back part 4 adapted to fit in a corresponding groove 2 and a flange 5 which is inclined towards the space to be sealed so that the pressure of the medium to be sealed acts to turn the ring about its section, thus pressing the face 6 on the surface to be sealed and pressing the back part into the groove. By making the ring of sufficiently elastic material and of open section, as shown for a piston in Fig. 7, the sealing effect is increased by spreading of the ring section. The ring 11 is a scraper ring and has axial passages 12 so that some lubricant can reach the rings above it. For sealing in two directions, rings or groups of rings may be fitted with their inclined faces pointing in opposite directions.

Filed: 1956-03-07
Abstract: 799,805. Air guns. BIRMINGHAM SMALL ARMS CO., Ltd. March, 7, 1957 [March 7, 1956], No. 7095/56. Class 119 In an air gun that has an air chamber formed in the rear end of a barrel 3, a piston moves forwards to compress the air and is fitted with a buffer 19 on its head 5 serving to cushion the impact of the piston on that end of the chamber 1 which is formed by the breech end 21 of the barrel. The buffer 19 is a ring of a material having high impact strength, tensile strength and elasticity, preferably moulded nylon. It is sprung into a recess 13 in the piston head where it retains a cupped piston ring 17 and a washer 15 against a flange 11 on the head 5. The washer 15 may also be of nylon, whilst the piston ring 17 is of leather and the head 5 and tube 7 are of metal. The piston head is carried on a tube 7 housing a spring 9 whose release after compression causes the piston assembly to move forward, compress air, and drive a projectile from the bore. The breech end 21 of the barrel 3 is tapered similarly to the piston head and buffer 19, but the outer surface of the latter projects slightly beyond the piston head to ensure contact with the breech end 21. Wedging of the piston head in the breech-end seating reduces rebound.

Patent GB-1306144-A (GB)
IPC: B25C1/04
Filed: 1970-02-16
Abstract: 1306144 Fastener driving tools D HAUBOLD [trading as DIETER HAUBOLD INDUSTRIELLE NAGELGERATE] 16 Feb 1970 [15 Feb 1969] 7364/70 Heading B4C A control valve assembly in a pneumatically actuated fastener driving device including a driving piston reciprocable in a cylinder is such that the piston will perform repeated working strokes whilst a trigger (not shown) is actuated. The assembly alternately couples a passage 5, communicating with the cylinder, with an air supply line 3 and vent passage 26. Actuation of the trigger raises a hollow stem 12 (see Fig. 3) to permit air from the line 3 to pass via bores 22, 46, and 36 and valve member 45 which has been raised from its seat and act on the bottom surface of a differential piston 31. The piston is raised from its collar stop 49 to permit air to act on the bottom surface of a valve member 4. The piston and valve member 4 thus move upwardly together. A sealing ring 18 on contacting a surface 21 of housing 10 interrupts communication between the passages 5 and 26, and further movement of the piston and valve member 4 opens communication between the supply line 3 and passage 5 (see Fig. 3) thus permitting the driving piston to be driven on a working stroke. Simultaneously air passes via ports 52 and annular passage 48 into chamber 43 and the piston 31 is forced downwardly relative to the valve member 4 to open chamber 35 to the vent passage 26 (Fig. 3). Venting of chamber 35 results in the valve member 4 and piston 31 being returned to their initial positions (Fig. 1) thus closing communication between the supply line 3 and passage 5 and reconnecting passages 5 and 26 to permit the driving piston to perform a return stroke. The annular passage 48 and chamber 43 are vented via a check valve comprising a sealing ring 56 when the piston 31 has contacted its stop 49 and the valve member 4 continues its downward movement towards a buffer 53. If the trigger continues to be actuated a further cycle of operations of the valve assembly will commence. The speed of upward movement of the valve member 4 can be varied by adjustment of a screw controlled throttle needle 47.

The dihydrobenzothiadiazine compounds are prepared by heating a 2:4-disulphamoyl -5-Z-aniline with a dihaloacetaldehyde or an acetal thereof, preferably in an inert organic solvent, in the presence of an acid catalyst e.g. in ethanolic hydrogen chloride; or by reducing a benzothiadiazine compound, preferably by the action of an alkali metal hydride or a dimetal hydride, suitably sodium hydride, sodium borohydride or lithium aluminium hydride. The benzothiadiazine compounds are made by reacting a 5-chloro-, bromo- or trifluoromethyl-2:4-di-chlorosulphonyl-aniline with a dihaloacetic anhydride or halide, reacting the resulting dihaloacetanilide with ammonia to give a 5-substituted -2:4-disulphamoyl-dihaloacetanilide and heating. Alternatively a 5-substituted -2:4-disulphamoyl aniline may be heated with a dihaloorthoacetate and refluxed in ethanolic hydrogen chloride.  Difluoroacetaldehyde is made by converting difluoroacetic acid to the acid chloride with benzotrichloride, reacting with dimethylamine to give N,N-dimethtl-difluoroacetamide and treating with lithium diethoxyaluminohydride.  Pharmaceutical preparations having diuretic and saliuretic properties comprise the above compounds of the invention and a carrier or diluent preferably in the form of tablets or elixirs for oral administration, but also in suspensions or solutions for parenteral injection.
