Title: Improvements in static converters of thermal energy in particular of nuclear origin, into electric energy
Inventor: KLEIN SIEGFRIED
IPC: H02N3/00
Filed: 1963-03-13
Abstract: 1,032,775. Discharge apparatus; thermo-electric devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 13, 1963 [March 16, 1962; April 12, 1962; Nov. 6, 1962], No. 10001/63. Headings H1D, H1K and H1X. [Also in Division G6] In apparatus for converting thermal energy into electrical energy, a hot ionized stream of vapour is passed between a pair of electrodes, which are maintained respectively at temperatures below and above the temperature of condensation of the vapour, to develop a potential difference between the electrodes. As shown, a series of pairs of electrodes are disposed on opposite sides of thin ionized vapour jets B n , Fig. 2. Each pair comprises a water-cooled copper electrode A n  and a non-cooled graphite electrode C n  electrically connected to, but thermally insulated from, the cooled electrode of the adjacent pair of electrodes. The vapour jets are formed by introducing a readily vaporizable and ionizable substance, e.g. potassium chloride/carbonate, suspended in a stream H o  of air or oxygen into gas burner flames. In an alternative arrangement, Fig. 5, cylindrical ionized vapour jets are employed between pairs of electrode A n , C n  have semi-cylindrical facing surfaces. In Fig. 8, the converter is disposed in the moderator 16 of a nuclear reactor. The ionized vapour jet is obtained from pools 20 of Na, Hg, H 2 O, Cs or K heated by the radiations from the reactor. The non-cooled electrodes G n  are of steel coated with uranium 13 or a compound thereof, neutrons from the reactor producing fission reactions in the coating. In a further arrangement for use in a nuclear reactor, a fissionable element 114, Fig. 10, immersed in heavy or light water, or Na or K, produces a plasma jet 115 which condenses on cooled electrode 116 producing a potential difference between electrodes 116, 120. A plurality of such converters, connected in series or in parallel, may be arranged side by side in a reactor. In a more elaborate arrangement, Fig. 11, the plasma jet is directed through a nozzle 120c, connected to a hot, rod electrode 139 and is deflected by plate 145 to condense on casing 116a which constitutes the cold electrode. Metal grid 137 prevents liquid droplets from passing through nozzle 120c. Mounting and sealing arrangements are described in detail.

Filed: 1938-04-04
Abstract: 513,661. Modulating systems. STANDARD TELEPHONES & CABLES. Ltd., and TERRY, V. J. April 4. 1938. No. 10258. [Class 40 (v)] A frequency translating system employing a plurality of non-linear impedance elements in approximately balanced relations has inserted in paths, where leakage current flows due to unbalance, networks having low impedance to the currents properly flowing and an impedance, intermediate between the forward and backward resistance of the non-linear impedances, for the most important frequencies applied to at least one of the inputs of the system. Telegraph signals applied terminals C, C cause either rectifier bridge B1 or B2 to be conducting, depending upon their polarity, and thus connect the carrier source S to the load T through transformers S1, S2, with a phase which reverses when the signal changes from marking to spacing or vice versa. Impedances R1, C1 in the carrier paths minimize the effects caused by leakage of the signal due to unbalance of the bridges B1, B2. Other more complex circuits than R1, C1 may be used to reduce interference ; or impedance elements already in circuit may be re-arranged for the same purpose. Specification 471,548 is referred to.

Title: Improvements in or relating to the method of and apparatus for forming bolts and thelike
IPC: B21K1/44
Filed: 1954-04-09
Abstract: 762,523. Forging bolts and the like. GUEST, KEEN & NETTLEFOLDS (MIDLANDS), Ltd., and ACTON BOLT, Ltd. April 9, 1954 [April 27, 1953; July 31, 1953; Oct. 9, 1953], No. 10455/54. Class 83 (4). In the manufacture of bolts and the like, the side faces of a preformed head are cold swaged to the required profile in at least two operations by a plurality of radially-acting dies 20 which operate so that there is always at least one unconfined side face during the swaging. Blanks 40 each having a substantially polygonal shaped preformed head, formed by one or more heading operations, are fed down a shoot to gripping fingers which transfer the blanks into the central aperture 21 of the swaging machine where their shanks are gripped between jaws 41. Means are provided to ensure that the preformed flats on the head are aligned with the swaging dies. The top face of the head is confined by an adjustable plug 46 carrying an ejector rod 47. Six swaging dies are operated in two sets of three in alternate sequence by rollers 25 carried by a rotating roller ring 26, 27 and cams 28 carried by a rotating cam ring 31. The roller and cam rings have peripheral teeth 30, 36 respectively in mesh with driving pinions and are both driven in the same direction but with a speed difference. When the cams and rollers come into alignment the latter act upon the outer ends 24 of the dies and press them inwardly to perform the swaging which occupies two revolutions of the roller ring and during which six blows are struck by each die; the relative rotary movement of the cams and rollers causes the rollers to move inwardly gradually during these two revolutions. During the next two revolutions the blank is ejected and a new blank is inserted. The cams are adjustably mounted in eccentric slots in the cam ring so as to vary the movement of the dies 20. The latter are retracted by a cam 37 which is secured to the roller ring and which engages the inturned ends 39 of the dies. The gripping jaws 41 have projecting fingers 5 engaging in a cam groove 44 in a gripper actuating ring 42, having peripheral teeth 45 in mesh with a driving pinion. Examples are given of the speeds of rotation of the cam, roller and gripper rings for swaging 75 and 60 bolts per minute. In another embodiment, Fig. 3 (not shown), rollers 25 are mounted in elongated slots in the roller ring and are spring-loaded therein so as to allow the rollers to roll over the ends of the dies and thus minimize friction between the cams, rollers and dies. The screwed plug 46 may be replaced by a reciprocating punch, particularly in the case when socketed bolts are being made. The six dies 20 may alternatively be operated in three sets of two, or one set of two or three dies may be used with the blank which is indexed between successive strokes of the dies. The invention may be used for making bolts with hexagonal, square, or octagonal heads, or for bolt heads with two flat side faces and two curved side faces.

IPC: A41C1/00
Abstract: 105,512. Kops, D. Oct. 16, 1916, Corsets.-A corset has at each side a rear band made up of a number of strips 16, Fig. 8, converging towards the hip section, to which they are attached either by sewing or by lacing, and either directly or through an auxiliary band 50. The rear edge may be sewn or laced to the corset. A stiffening or spacing member 22 may be used for the strips, and the band may be interrupted by a section of elastic material. Alternatively, the strips may converge to a point and be secured by hooks and eyelets. A second band of strips, converging to a point and similarly secured, may be provided on the front at each side, in addition to the gradually convergent rear band, and this may fasten inside or outside the corset. Or the second band may be of the kind described in Specification 1175/15. In the double band arrangement, each band is separately secured at the hip section, or each may be secured to an intermediate piece, which may in turn be secured to the corset. The self-reducing strap described in Specifications 23407/12 and 16288/14 may be used with the rear strap. In the form shown in Fig. 12, an elastic front strap is secured at each end to an auxiliary band 105, 112, and the rear strap is secured partJy by interlacing with the rear lacing of the stays and partly through an auxiliary band, the eyelets 100, 102 being out of register. The laces are passed outwards through eyelets 104, 115, 116 to enable the adjustment to be effected from outside. Specification 12502/15 also is referred to.

Title: Improvements in or relating to amplifiers for "echo" sounding apparatus
IPC: G01S7/527
Filed: 1939-04-05
Abstract: 527,264. Echo-sounding apparatus. GLAZER, D. S. T., and MARIE, R. April 5, 1939, No. 10643. Convention date, April 5, 1938. [Class 118 (ii)] [Also in Groups XL and XXXIX] An amplifier for aerial or submarine echo sounding apparatus comprises a band-pass filter and a two-stage tuned amplifier coupled by a tuned transformer to a gas discharge device which operates the chronographic apparatus. The Figure shows amplifying valves 31, 32 with a filter 36 and tuned transformer input 37 and a tuned coupling 41, 42. The output is applied through tuned transformer 47 to a gas discharge device 49, limiting being effected by diodes 86. The tuned circuits are shielded by thick ferromagnetic screens 50 ... 52. Operation by interference is reduced by accurate adjustment of the supply voltages by barretter 53 and gas discharge regulator tube 56. Cam 64 applies a prohibitive bias to amplifier 31 during operation of the emitter 67 and progressively increases the sensitivity of the amplifier the longer the period before the echo is received. Cam 74 ensures that the non-receipt of the echo for a pre-determined time indicates that the vessel is in a safety zone. The time constants of relays 60, 77 are adjusted by condensers 78, 79 and by resistance 80 to produce signals of adequate duration. The Specification as open to inspection under Sect. 91 comprises also a microphone construction in which the unit is protected from acoustic and mechanical vibration by insulating material 6, 7, 8 and from electromagnetic interference by a screen 12. Fig. 1 (Cancelled). The horn is shaped to be selective to the frequency received. This subject-matter does not appear in the Specification as accepted.
