Title: Improved apparatus in and relating to trail carriage guns mounted on endless tracksfor varying the height of the line of fire of the gun
IPC: F41A23/34
Filed: 1922-12-21
Abstract: 202,905. Schneider et Cie. Nov. 25, 1922, [Convention date]. Addition to 182,813. Field carriages. - Relates to carriages having endlesstrack trucks and means for varying the firing-height of the carriage above these trucks as described in the parent Specification, and consists in the provision of springs for balancing the weight of the parts to be raised and lowered. As shown in Figs. 1 and 3, the carriage A is connected to the endless-track trucks C by a shaft B', so that the trucks can be rocked about this shaft by means of handles J adapted to be fitted to spring pawls H, H', which, at the ends of the rocking movement, snap alternately into a notch g in a sector G fixed to the carriage. When the trucks are rocked from the position shown to the other extreme position, the rear part of the truck and the gun are raised and the front end of the truck only bears on the ground. A spring buffer R is interposed bv means of a rack and sector S between the carriage and the truck, so that the spring is compressed by the weight of the parts when they are lowered, and the reaction of the spring helps the reverse motion. The sectors G may be locked to the shaft B<1> by a pivotal spring bolt T by unscrewing a screw T', thereby allowing the nose of the bolt T to enter a notch in the sector G. In a modification, Fig. 6, the carriage axle-box B<3> is raised and lowered in a vertical slot, and balance springs R are arranged in telescopic toggle-like links X.

Title: Wire printer mechanism
IPC: B41J2/24
Filed: 1954-12-03
Abstract: 772,512. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 3, 1954 [Dec. 7, 1953], No. 35039/54. Class 100(4) In a wire printer such as described in Specification 763,407, where the wires are carried by a reciprocable, print head towards and away from the platen for printing, the print head is moved by drive wires slidable in curved tubes which are straightened to reciprocate the head. 'Tubes 15 surrounding print wires 16 are confined so as to prevent longitudinal movement in a print head 10 slidable in a frame 12. The wires are set by a control rod 38 in a housing 19 as described in Specification 763,407. Drive wires 22 are secured in openings 94, Fig. 4, in the print head 10, while flexible tubes 28 surrounding them are secured in grooves 92 in a part 88 of the frame 12. The other ends of the wires 22 and tubes 28 are attached to slides 24, 30, Fig. 1, respectively, in guides 96 and are reciprocated therein by cam followers 26, 32 controlled by a double lobed cam 34. The printer operates cyclically and, with the print wires 16 set in a previous cycle, the tube cam follower 32 drops off the cam high 18 degrees before the follower 26, thus causing the tube 28 to be straightened so that the wires 22 project from the print head end cause it to advance and effect printing. When the wire follower 26 leaves the cam high, it withdraws the wires 22 in the tube thus quickly overcoming their straightening effect and stopping the forward movement of the print head 10, and finally, as both followers restore, withdrawing it to its initial position. When a double lobed cam is used during this restoration, the relative movement occurs between the drive wire tubes which could be used to effect resetting of the print wires. This relative movement can be prevented if two separate cams are used. The continued forward movement of the head 10 after printing aids the normal rebound to restore the set print wires 16 before the head is returned to its normal position thus allowing extra time for the re-setting of the wires for the next operation. The drive means may be used with banks of printers or to effect embossing, punching or stencil cutting.

Title: Improvements in or relating to lasers
IPC: H01S3/105
Filed: 1962-09-14
Abstract: 1,018,826. Lasers. SIEMENS & HALSKE A.G. Sept. 14, 1962 [Sept. 14, 1961; Oct. 4, 1961], No. 35070/62. Heading H3B. The beam of radiation in a laser crystal undergoes multiple reflections at various surfaces of the crystal before a part of the radiation energy emerges from an exit surface; at least one of the reflections being caused by the process of total internal reflection at a crystal surface. In the embodiment of Fig. 1 a square cross-section laser crystal 1 is used in which the beam 11<SP>1</SP> is directed along a spiral path by total internal reflection at the inclined surfaces of truncated pyramids I<SP>1</SP>. The outside truncated pyramids have faces 11 and 12 respectively cut into them to provide two surfaces between which the radiation beam is reflected, the face 11 being partially reflecting so as to permit an emergent beam. Oscillation of the laser output during the period of a pumping pulse is damped by making the transparency of the face 11 small. In the square cross-section crystal 41 shown in Fig. 4 the beam emerges and passes through a glass transparent body 42 by using the tunnel effect at a surface of total internal reflection of the beam. The distance D between the crystal 41 and the body 42 is less than about ten wavelengths and is adjustable by moving stops 45, 46 against which the transparent body is pressed by a spring 43. Variation of this distance D varies the transparency of the output face. It is stated that the power transmitted by the output face is preferably equal to the power absorbed there. If the refractive index of the crystal is less than 1À4 a cross-section in the form of a polygon with an even number (>4) of sides must be used to obtain total internal reflection. The laser crystal may be ruby, calcium tungstate, strontium tungstate, barium tungstate, barium molybdate or strontium molybdate.

Title: Process for the steady state measurement of the subcriticality of a nuclear reactor
IPC: G21C17/10
Filed: 1972-07-27
Abstract: 1365775 Monitoring and testing reactors GES FUER KERNFORSCHUNG mbH 27 July 1972 [27 July 1971] 35070/72 Heading G6C Subcriticality of a nuclear reactor which is shut-down is measured by causing after-heat production to raise the core to successively different temperatures to produce reactivity change and neutron flux change from which the subcriticality is determined. A neutron detector 10 measures the change, ##, in neutron flux caused by a temperature change, ##, which itself is measured by a sensor 8 responsive to the sodium coolant outlet temperature. Where insufficient neutrons are produced by spontaneous fissions in the fuel, a synthetic neutron source is placed in the core 1. The induced reactivity change, #k, is obtained from the expression: #k = c# . ## where: c# is the known temperature coefficient of reactivity for the reactor core. The suboriticality is then determined from the expression: #k = #k.#/## where: #k is the subcriticality. # is the measured neutron flux prior to raising the temperature. As shown, the reactor coolant loop includes a circulation pump 2 and one side of a heatexchanger 4 whose other side forms part of a secondary coolant loop including a circulation pump 3 and flow-control valve 5. The different core temperatures are obtained by varying the primary or secondary coolant flow rate by means of the pumps 2, 3 or valve 5, or the primary coolant temperature also by means of the pumps (to vary the heat-exchange rate at heat-exchanger 4). The determined subcriticality is of importance, for safety reasons, during fuelling of the reactor.

Title: Improvements in or relating to methods of and apparatus for separating the components of a liquid system or solution
IPC: C11C1/10
Filed: 1946-11-28
Abstract: <PICT:0637726/III/1> A mixture of water, an oil, e.g. stearic or oleic acid, and a volatile organic solvent such as methanol, which is miscible with water, but does not form an azeotropic mixture with it, is separated by introducing it into a stripping column down which it flows in countercurrent to steam from a boiler at the base of the column into which the stripped water/oil mixture is conducted. The boiler is in communication with a settling receiver where the water and oil stratify, the oil layer being periodically withdrawn.  The solvent vapours, which are preferably of approximately the same composition as the water/solvent component in the original mixture, are withdrawn from the top of the column and condensed.  In an example, a feed mixture of 49 per cent fatty acid and 51 per cent of methanol/water solvent-consisting of 90 per cent methanol: 10 per cent water-was fed in the top section of an eight-plate bubble column 1, the stripped oil/water mixture dropping into a boiler working at 104 DEG  C. and having a boiling section 5 separated by a perforated baffle plate 12 from a stratifying section 6.  Oil is withdrawn through outlet 8, the oil-free water flowing back to the boiling section through passageway 13.

Title: Improvements in advertising and display devices with moving effect
IPC: G09F13/00
Filed: 1938-12-05
Abstract: 522,179. Moving signs. AXE, E. C. (SHIGLEY, W. W.). Dec. 5, 1938, No. 35382 [Class 3 (i)] Lamps 29 are carried on a spider 1 rotating about a spindle 14 mounted on the outer end of an arm 2 turning on a shaft 7. An electromagnetic brake comprises a shoe carried by the arm 2 and acted upon by a solenoid energized through a rheostat and a brush touching a rotating contact. The spider is positively driven from a motor 3 through gearing 9, 10, 12, 13, the wheels 10, 12 being unitary and loosely carried on the shaft 7. The shaft 7 is driven through friction discs 15, 16, the latter of which is positively rotated from the motor 3 through worm gearing 18, 19. The disc 15 is splined on the shaft 7 and can be slid along same under pressure by a spring 28 by a cam 20 bearing on a block 21 having a finger 23 engaging a groove 24 on the hub of the disc 15. The cam 20 is mounted on a shaft 30 geared to the motor 3, but the gear wheel 35 thereon can be withdrawn from engagement with its partner 32 by retracting a sleeve 36. The cam 20 can thus either rotate constantly and give a varying speed ratio to the rotations of the spider 3 and of the arm 2, or can be stopped and adjusted to any position and locked therein to give a selected constant speed ratio. The lamp contacts are made through strips 44 and 48 and an insulated rod 49 passing through the shaft 7. A modification is described in which the arm 2 extends on both sides of the shaft 7 and carries a counter-weight to balance the spider. The spider end has a centrifugal brakeclutch which causes the arm 2 gradually to rotate with greater speed, and a solenoid-operated brake is provided to bring the arm to a stop. In this form the device may be double-sided to display a lamp-carrying spider from two directions. Specification 454,293 is referred to in the Provisional Specification.
