Title: New and improved explosive elements
Inventor: DAVIDSON SAMUEL HENRY
IPC: F42B3/00
Filed: 1954-11-08
Abstract: 776,185. Filling hydrostatic pressure-resistant ammonium nitrate explosive charges. IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 29, 1955 [Nov. 8, 1954], No. 32220/54. Class 9 (2). Explosive elements for use at high hydrostatic pressure are produced by packing a charge of an ammonium nitrate powder explosive containing not less than 0.1 per cent. and not more than 1.0 per cent. of water, based on the ammonium nitrate, into a sheet metal canister, subjecting the canister after sealing to such a temperature and for such a time that at least a layer of the explosive close to the sides of the canister attains a temperature which is at least the transition temperature for ammonium nitrate IV to ammonium nitrate III, i.e. 32.3C, is below the fusion point of any solid fusible organic sensitizing agent which may be included in the explosive, and does not exceed 80C and thereafter allowing the canister to cool so that the explosive which is at least at the transition temperature is converted into hardened explosive. The composition may contain at least 75 per cent. ammonium nitrate and usual ingredients, e.g. vegetable tissue, sugar, starches, trinitrotoluene, aluminium powder, orthonitrotoluol, and dinitrotoluol oils. The canister may be 0.012" thick metal, and heating may be in air or water, but is preferably to 60-70C by total immersion in water, so that the exposive is hardened throughout. In examples ammonium nitrate (100 per cent.-30 B.S.S., 98 per cent.- 60 B.S.S., 83 per cent.-100 B.S.S., 70 per cent.- 120 B.S.S., 34 per cent.-170 B.S.S., and 7 per cent.-240 B.S.S.), containing Acid Magenta is mixed with orthonitrotoluol with or without water wet nitrocellulose (4) (1), or with anthracite and orthonitrotoluol or trinitrotoluene (2), (3), and the resulting compositions are loosely packed in tins and roll seamed.

Title: Improvements in vulcanisation
IPC: B29C45/73
Filed: 1959-09-22
Abstract: <PICT:0898830/IV (a)/1> <PICT:0898830/IV (a)/2> Rubber-like materials (i.e. natural or synthetic rubber) are vulcanized by preheating to a temperature approximating to but not exceeding a "limit temperature" (defined as the temperature which cannot be exceeded, even for an instant, without the unvulcanized condition being replaced substantially instantaneously by a vulcanized condition) and charging the preheated material into a mould heated to a temperature appreciably above the "limit temperature" so as to bring the temperature of the material rapidly above the "limit temperature" throughout its mass.  The preheating temperature should be such as to provide a "scorch time" longer than the time required for charging the mould and the mould temperature limited to that which the material can endure without deterioration.  The result of the application of this method is claimed to be the reduction of vulcanization times which previously were reckoned in periods of minutes to periods which can be reckoned in seconds.  A suitable mould is shown in Fig. 1 comprising two parts 1, 2 insulated on the outside by lagging 9, 10 and containing electric heating resistances 3, 4, 5, 6. Alternatively, the mould shown in Fig. 4 may be used, the two parts 20, 21 being of insulating material embedded in a metal reinforcing body and provided with internal metal casings 22, 23 heated by an electric resistance 24.  With this mould, the preheated material can be introduced into the mould cavity before the casings 22, 23 are heated which is of particular importance if large moulds are to be filled without the risk of scorching. Other moulds (not shown) have only one metal casing covering all or part of the cavity surface of one of the mould parts. Alternatively, a continuous method of moulding in which the material is preheated before being fed on to a rotary moulding device or during the first part of its progress on the device, or a batch method of moulding, may be used.

Title: Machine tool indicator
IPC: B23Q17/22
Filed: 1946-11-01
Abstract: 618,387. Boring and drilling gauging devices. WILLIAMS, L. S., and DEFIANCE MACHINE WORKS, Inc. Nov. 1, 1946, No. 32431. [Class 83 (iii)] [Also in Group XIX] A linear-movement indicator for a machine tool part is operated by a rack which is guided in a stationary frame and has a disengageable connection with the machine tool part so that the indicator may be rendered inoperative when not required; the rack engages a spiral gear and can be flexed laterally at any point along its length to move it up or down the spiral of the gear for the correction of errors in the drive to the indicator. As applied to a horizontal boring-machine, the indicator 20, Fig. II, is mounted on the saddle and comprises a pointer 22 reading against a scale 27 graduated in thousandths of an inch and an integrating pointer 25 reading against a scale 26 graduated in inches. The zero mark of the scale 27 can be set at any position by rotating the annulus 21 by means of a knob 43 having a friction drive engaging the rim of the annulus. The clock gearing operating the two pointers is driven by a tube 63 connected by bevel gears 74, 75, Fig. VIII, to a shaft 76 which is mounted in the saddle and has a spiral gear 80. The gear 80 engages the rack 87 which is carried by a slide 85 supported on rollers 84 and can be flexed at any point by a series of screws 89, 90. The slide 85 has a plug 106 that is normally held in a socket 107 on the spindle ram 17 by a permanent magnet in the socket, but the slide can be prevented from moving with the ram by a handle 118, Fig. II, that places a finger in the path of a pin on the slide so that the magnetic connection between it and the ram is broken as the ram moves forward. The plug 106 is connected to the rack slide by flexible ribbons 94, 98 placed at right angles to each other so that it easily aligns itself with the magnetic socket 107. The rack slide can be moved to engage with the ram at any position of the latter by a handle 125, Fig. XIX, which drives the pinion 80 through a spring-loaded friction clutch 130, gearing 128. 134 and a sliding clutch having pins 142 engaging the pinion 75.

Filed: 1929-10-26
Abstract: 342,258. Low temperature carbonization. PATENTAKTIEBOLAGET GRONDAL-RAMEN, 3, Norrmalmstorg, Stockholm. Oct. 26, 1929, No. 32607. Convention date, May 25. [Class 55 (i).] In a low temperature carbonization process the coal is continually conveyed in deep containers, forming continuous grooves, through a coking chamber in which it is first heated to remove some of its volatile constituents (250‹ to 300‹ C.) before final coking takes place, the containers being heated by gases which are circulated around them and through heat exchangers. Coal from a hopper c is pressed into narrow and high containers b on an endless supporting member a. Gases, which may be those generated, or extraneous gases, are circulated by fans g through heat exchangers f and down past the containers b. Owing to the generation of gas there is a gradual longitudinal flow towards the gas outlet h. The coke is discharged through a conduit t. The heat exchangers are heated by hot combustion products passing through them from an inlet flue k to an outlet m, and the temperature of each zone may be separately controlled by dampers in the heating gas flues.

IPC: H04N5/10
Filed: 1949-12-21
Abstract: 691,858. Pulse discriminating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 5, 1950 [Dec. 21, 1949], No. 32684/49. Class 40 (vi). A pulse width discriminating circuit comprises a valve to which a series of narrow and a sequence of wide pulses are applied, an integrating circuit producing from the wide pulses further pulses which are of greater amplitude than those produced from the narrow pulses and a time constant network which causes the further pulses derived from the wide pulses to be of progressively decreasing amplitude. Fig. 1 shows the application of such a circuit to separating frame synchronizing pulses from the combined picture, line and frame synchronizing signals in an interlaced television system. The combined signal in which the synchronizing pulses are of positive polarity is applied to the control grid of valve 1 which is biased so that the negative going picture signal is ineffective and does not appear in the valves output circuit. The anode circuit of the valve 1 comprises a ringing circuit constituted by inductor 14 tuned by its self capacity and a damping resistor 13, and an integrating network 7, 8 and the screen-grid circuit comprises a network 11, 12 which has a time constant longer than that of the integrating circuit 7, 8. When the combined synchronizing signal is applied to the control grid of valve 1, narrow line synchronizing signals are integrated to produce an anode potential change of valve 1 as shown at 10 in Fig. 3, the spikes shown at 15 being caused by circuit 13, 14 ringing. The wide frame synchronizing pulses produce integrated pulses as shown at 9 in Fig. 3, but the capacitor 12 has such a value that the peak cathode current of valve 1 commences to fall after the first wide pulse so that the amplitude of the pulses 9 progressively decreases. Diode 16 is biased to pass only those signal peaks which occur below the chain-dotted line shown in Fig. 3, the resulting output signal being employed to trigger a frame pulse generator valve 19. In order to reduce the possibility of line frequency transients passing to valve 19 via the inter-electrode capacity of diode 16 a further diode 20 is connected with its anode in parallel with that of diode 16 and earthed via a small value capacitor 21.
