Title: Improvements in or relating to apparatus for use in surveying for radioactive substances
IPC: G01V5/02
Filed: 1959-02-03
Abstract: 909,207. Photo-electric direction-finding and position-finding apparatus. TAKAHASHI, K. Feb. 3, 1959 [Feb. 5, 1958], No. 3792/59. Class 40 (7). In surveying apparatus for locating radioactive ores, a scanner, Fig. 1, comprises a cylindrical vessel 2 containing a scintillation counter 1, e.g. sodium iodide, a photo-electric amplifier 6 and a lead shield 3 provided with an aperture 9 between two walls 4, 5, which is rotated around the axis of the vessel 2, pulses produced by the photo-electric amplifier due to the impingement of γ-rays on the scintillation counter being used to indicate on a C.R.T. the direction and intensity of the γ-rays. In Fig. 4, the deflection coil 22 of the C.R.T. 23 is rotated in synchronism with the shield 3 by means of synchro generator and receiver 18, 19. The 18 kc./s. output of a sawtooth generator 50 is fed to a 10: 1 frequency-divider 51 to produce pulses which provide concentric coordinates 40, Fig. 3, on the screen of the C.R.T. as the survey vector scans. The latter is produced by a sawtooth wave operating at 360 c./s. derived from a second frequency divider 52. A cam 53, rotated in synchronism with the shield 3, operates contacts 54 of a flashing arrangement 55, 56 which provides azimuthal co-ordinates 41 on the screen. The pulses derived from the crystal 1 may be passed to the C.R.T. via a network of Type A or B. The former, which is preferably used for measuring weak radiation, produces a display as shown in Fig. 3A, the density of the dots in any radial direction representing the intensity of radiation. Type B network contains a pulse integrator 61, a diode clipper 62 fed with the output of 61 and a reference wave of the sweeping frequency of the survey vector, and an automatic plotter, and it produces a continuous curve display as shown in Fig. 3B. By plotting readings taken at two different positions the location of a particular radiation source may be determined.

Abstract: 720,113. Forging. WIGGIN & CO., Ltd., H. Feb. 10, 1953 [Feb. 13, 1952], No. 3872/52. Classes 83 (2) and 83 (4). Making turbine blades.-A deep die press has a punch 6 and a die 2 which co-operate to enclose the workpiece 56 during the pressing operation, the recess in the die being defined by a stationary central piece 10 and two end pieces 12, 14 which can rock with respect to the central piece from a position they occupy during the pressing operation to a position in which they cause the workpiece to break contact with the central piece and partly with both end pieces. The latter have bevelled faces 34 which mate with the bevelled faces 36 of the stationary central piece 10. These end pieces are each mounted in a die holder 28 pivoted on a spindle 30 and are lifted during the upstroke of the punch by rods 46 having nuts and washers 50, 52, which are engaged by a crosshead 44 of the press ram 8. During the pressing operation the holders 28 each rest on strip 40 secured to the bolster 4. The press is used for forging a turbine blade from a dumb-bell-shaped blank of nickel/chromium-based alloy which blank is formed by hot rolling a billet in an apparatus of the kind described in Specification 668,882. The rolled blank may be roughly machined before forging, to bring it to the definite volume required., and it is so shaped that no part thereof initially touches the joints between the die pieces and therefore no flashes are produced. After forging the blade may require final machining although this may be unnecessary with accurately forged blades. Single-rooted blades may also be forged from mushroom-shaped blanks.

Filed: 1939-02-08
Abstract: 524,833. Making hollow glass blocks. CORNING GLASS WORKS. Feb. 8, 1939, No. 4161. Convention date, March 3, 1938. [Class 56] Relates to a process for making sealed hollow glass articles, such as building blocks or double window panes, in which complemental preformed parts are heated along their edges and welded together and the characteristics of the atmosphere enclosed in an article are controlled, as described in Specification 518,652. According to the present invention, a gas in other than gaseous form is supplied to at least one of the glass parts, the gas is allowed to volatilize to sweep out air from the complemental parts, and the parts are then joined together in timed relation with the volatilization so as to trap the desired amount of gas within the finished article. The parts G, G<SP>1</SP> of a hollow glass brick may be supported, heated, and moved into contact with one another as described in the prior specification, and shields 38, 40 may be used to enclose the parts during the sealing operation. While the parts are in the position shown, a charge of gas in liquid form may be run into the part G<SP>1</SP>. A charge of gas in solid form, such as solid carbon dioxide, may be supplied from a mass 86 contained in a cylinder 84 fitted with an air-operated piston 90 and a rotating cutter 96. Other substances such as ammonium carbamate, nitrosyl chloride, or alkyl amines may be used instead of carbon dioxide.

Title: Improvements in or relating to free-piston engine gas compressors
IPC: F02B71/00
Filed: 1934-02-08
Abstract: 427,668. Two-stroke-cycle directacting engines. JUNKERS, H., 21, Hauptmann Loeper Platz, Dessau, Anhalt, Germany. Feb. 8, 1934, No. 4209. Convention date, Feb. 16, 1933. [Class 7 (ii)] [See also Groups XXVIII and XXIX] In a free-piston gas compressor the charge of fuel to the internal-combustion engine is adjusted to vary the stroke and simultaneously the suction or delivery pressures or both are adjusted automatically to maintain constant the recoil energy. The internal-combustion engine cylinder 1 has an inlet port 3 and an exhaust port 4, and pistons 2 are connected to pistons 10 of the compressor cylinders 5, 6. The racks 21, 22 engage a pinion 23 and a cam 26 actuates, through a lever 27, the plunger 24 of a fuel injection pump supplying an injector 29. The output of the pump 25 is adjusted by rotating the plunger 24 through pinion 30 by a spring loaded piston 32 subjected to pressure from the pressure of the receiver 14. The ratio of delivery pressure to suction pressure above the value set out in Specification 425,708, [Group XXVIII], is termed a high pressure ratio and below that value is termed a low pressure ratio. For high pressure ratios the delivery pressure should be decreased when the stroke is decreased and for this purpose a throttle valve 9 is provided which consists of a piston 44 secured to the valve 43, wherein the compressor delivery pressure upon the annular surface 45 together with the receiver pressure upon the surface 43<1> acts in opposition to the spring 46. A fall in the receiver pressure results in a greater delivery pressure being required to overcome the spring, whilst at the same time the pump 25 is adjusted to increase the fuel supply. If the pressure ratio is low the delivery pressure should be increased when the stroke is decreased and the throttle valve 9 then consists of a double beat valve 53, 54 attached to a piston 57 loaded by a spring 59 and subjected to delivery pressure on the surface 57<1>. The spring abutment 61 is adjusted by receiver pressure through pipe 60. The valve 9 may be omitted and the same result obtained by employing positively driven adjustable valves upon the compressor. Throttle valves may be employed in the suction pipes. The Specification as open to inspection under Sect. 91 states also that the discharge from the compressor cylinder does not commence until the inlet and exhaust ports are sufficiently open to permit efficient exhausting, scavenging and charging. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,120,691. Refrigerating. WORTHINGTON CORP. 31 Jan., 1966 [13 April, 1965], No. 4255/66. Heading F4H. In an absorption system using lithium bromide as absorbent and water as refrigerant, the generator is heated by low pressure steam which is passed from a steam header 110 through a tube bundle 44 in the generator to a condensate header 118 from which condensate makes a pass 44a through solution in the generator to cool the condensate to a temperature at which it will not flash on discharge to atmosphere. As illustrated, condensate from the pass 44a passes to a portion of the steam header formed by a partition 112 for discharge at 120. Baffles 104 in the generator cause solution to follow a sinuous path over the tube bundle from an inlet (38) to an outlet (46), Figs. 1 and 3 (not shown). In a modification, Fig. 4 (not shown), condensate from the partitioned portion of the steam header makes a second pass to a partitioned portion of the condensate header before discharge, and starshaped inserts (126) are included in the condensate passes (44b) to inhibit passage of steam. Operating temperatures and pressures are disclosed.

Abstract: 330,553. Parsons, Sir C. A., Cook, S. S., and Douglas, L,. M. Feb. 11, 1929. Toothed gearing.- In gearing for coupling an exhaust-driven turbine to a reciprocating engine, or for other purposes, accurate meshing of the teeth independent of the flexure of the main shaft is secured by locating the bearings for the turbine-driven pinion in a casing which is centred on the main shaft of the reciprocating engine. As applied to a double-reduction gear, a casing C, Fig. 3, is centred in bearings D embracing a main shaft A. The casing contains bearings for the wheels F, K and G. The pinion G may be connected to the turbine by a long and flexible shaft, or a flexible coupling may be used. The weight of the gear-wheel B is taken by the external bearings of the engine, but the casing may be supported by a spring S. Rotation of the casing about the shaft A is prevented by coacting abutments M, N which may have flat or spherical surfaces concentric with the axis of the high-speed pinion G, with or without interposed rollers M', and which may be bolted together by bolts and spring or other suitable washers. In a simpler form applied to single reduction gearing, rotation is prevented by a link L, Fig. 1, below the axis of the pinion. The link may be resilient and may co-operate with a similar link above the axis. Lateral movement of the casing may be prevented by spring or other abutments, which may comprise collars on the main shaft, or foundation abutments. The teeth may be straight or helical.
