Abstract: 1, 059, 648. Determining the parameters of raceways. ZKL VYZKUMNY USTAV PRO VALIVA LOZISKA. Aug. 31, 1964 [Oct. 31, 1963], No. 35505/64. Heading G1M. In an apparatus for checking the parameters of races e.g. ball bearing races, the races 1 are fed in along a shoot 2 and moved through a cleaning device 17 by a reciprocable ram 3 on to a platform 5 mounted on a reciprocable bar 8. In the displaced position of the bar 8 the race 1 is supported by contacts 21, 22 and between pivoted levers 11, 12. A rotatable disc 15 is then moved to the left (as shown in Fig. 1) inserting its centre part into the bore of the race to impart rotation to the race 1. A guard roller 13 lying in contact with race 1 is rotated by its movement. The periphery of the roller 13 is provided with a slotted disc 13c, so that by illuminating the slots the number of revolutions of the roller may be detected by a photo-electric device. To determine the shape deviation of the raceway, the raceway is mounted on contacts 21, 21, contact 22 being rotatably mounted on spring blades so that at any deviation the contact 22 moves to operate an electrical detector. The magnitude of the diameter of the raceway is determined by an air pressure jet incorporated in the contact 22. The diameter and non-sphericity of the raceway are also determined by an electrical stylus 23.

Title: Improvements in and relating to the continuous milling of plastic materials
IPC: B29B7/52
Filed: 1954-12-08
Abstract: 778,678. Continuous-discharge mixing- machines. UNION CARBIDE & CARBON CORPORATION. Dec. 8, 1954 [Dec. 10, 1953], No. 35522/54. Class 86 In a continuous-discharge mixing and milling device for the compounding of plastic materials such as synthetic and natural rubbers and synthetic resins, a smooth-surfaced, cylindrical roll 10 is mounted concentrically in a smooth-surfaced, cylindrical casing 12, the casing having an inlet 22 for the plastic material at one end and an outlet 24 for the milled material at the other and being provided with - a longitudinally extending dam 15 projecting inwardly towards the roll to leave a milling clearance 16 between the roll and the dam. Seals 17, 18 are provided at respective ends of the roll 10. In operation, the plastic material which does not pass through the milling clearance collects in the space 13 ahead of the dam 15 and, due to the roll rotation, a pressure is built up in the collected material which acts to propel the material through the mill and through the outlet 24 in a steady flow. If, for example, the viscosity of the material changes or the roll speed alters, the delivery flow rate will be affected but will 'be restored quickly to the desired rate by an appropriate increase or decrease in the quantity of material collecting behind the dam with consequent increase or decrease in the propelling pressure, the parallelsided form of space 13 ensuring that the pressure varies linearly with the said quantity of material. In modifications, mills having two, three or four rolls and. in which the sides of the collecting space diverge slightly in the direction of roll rotation are described.

Title: Firing of projectile fuses or igniters
IPC: F42C17/04
Filed: 1970-07-22
Abstract: 1317977 Fuzes and igniters GENERAL ELECTRIC CO 22 July 1970 [22 July 1969] 35568/70 Heading F3A [Also in Division H4] A method of detonating a projectile fuze or rocket motor igniter at a predetermined distance along its flight path, comprises transmitting to the fuze or igniter radio frequency pulses which are counted and cause detonation at a predetermined summation. The predetermined distance is measured with a laser and an X-band radar transmitter issues pulses at a rate inversely proportional to the measured distance. In one embodiment, Fig. 2, the fuze comprises an antenna 26, an electronic device 28 for amplifying and counting the pulses received by the antenna, a thermal battery 30, and a detonator 38 carried by a centrifugal rotor 32. A C-shaped element 44 locks the rotor in a safe position but is expanded under the effect of centrifugal force to release the rotor for movement towards the armed position. An electrical contact 42 touches the base of the battery in the armed position and conducts current to a bridgewire 40 when the predetermined number of pulses has been received. The battery 30 is activated by melting a solid electrolyte with the heat from a charge ignited by a percussion cap, the cap being ignited by the set-back of a striker on firing the projectile. In another embodiment, Fig. 7, an igniter for a rocket motor comprises a nozzle plug 202, an antenna 206 wound on a dielectric core 208, a pulse detector 210, a thermal battery 214, a counter 216, a detonation initiator 218, and an igniter 220. The counting device in both the fuze and igniter is an electronic fixed-set digital counter consisting of twelve flip-flop stages in a cascade configuration. An automatic reset circuit for the counter precludes premature detonation whilst the voltage of the battery is building up.

Abstract: 773,867. Induction generators. AERO MATERIAL AKTIEBOLAGET. Dec. 13, 1955 [Dec. 16, 1954], No. 35745/55. Class 35. In a variable-speed A.C. generator comprising two asynchronous machines G 1, G2 on the same shaft and with their rotor windings 3, 4 connected together in star and their stator windings 9, 5 connected in series, similar to that described in Specification 700,036, the output voltage and frequency are controlled by a small constant frequency source F whose output is injected into the stators through a saturable transformer Tl. The magnetizing current is supplied from condensers through a saturable transformer T2 whose effective ratio is controlled by a saturating winding 8 fed from rectifiers 14 and controlled in accordance with the load power-factor by a potentiometer 19 adjusted by a Ferraris phase angle detector 20, 21. The rotor windings are energized by currents induced by mechanically rotating the stator 9 with respect to stator 5. The angular displacement is adjusted with the speed if necessary, particularly at low speeds. At higher speeds which require less adjustment, the voltage is controlled by a saturating winding 10 fed by the difference between the rectified line voltage and the rectified voltage of a tachometer generator 16, the current being adjusted by a variable resistor 15. The output voltage is adjusted by means of a variable resistor 17 controlling the current in the saturating winding 11 of transformer T1. This resistor 17 may be further governed by a voltage regulator to provide a close control. The presaturating winding 10 of machine G1 is placed in slots 52 outside the winding slots 51, the coils being wound round cores 53, as shown in Fig. 2.

Title: Improvements in laundry ironing machines
IPC: D06F67/04
Filed: 1935-12-27
Abstract: 468,070. Ironing - machines. MANLOVE, ALLIOTT, & CO., Ltd., and HASTIE, W. A. Dec. 27, 1935, No. 35803. [Class 138 (ii)] Goods are fed to an ironing-machine 1, 2 by the operator securing their leading edges to clips carried by transverse bars 13 mounted on wheels 14 which traverse rails 15, 16 in a closed path. The loaded carriage 13, 14 is pushed by the operator to a point where it is stopped by a pin 34. This pin is withdrawn in timed relation to the working of the feeding device and the carrier descends to a point X. It is there engaged by a catch 9 on a horizontally-reciprocating member 7 and advanced up the inclined portion of the track 16 so that the trailing portion of the article is laid over the usual feed tapes 3. The friction roller 5 that co-operates with the feed tapes is raised by a cam 31 associated with the mechanism that reciprocates the member 7 to permit the passage of the carrier underneath it. At the top of the incline the clips on the bar 13 are released by an abutment 17, the carrier is raised by the cam portion 8 of the member 7 on to the upper track 15 for its subsequent return along that track on the return movement of the member 7. The article has meanwhile been wholly deposited on the tapes 3 and passes to the ironer ; in so passing it depresses a lever 33 which breaks the circuit to the motor operating the reciprocating mechanism for the member 7 until the article completely passes the lever which then rises and restarts the reciprocation of the member 7. Immediately in front of the feed tapes 3 are arranged transversely two pairs of endless conveyers, one pair 22 being above the track 16 and the other pair being below it. The members of each pair move in opposite directions in such a way that the lower laps of the top pairs and the upper laps of the lower pairs travel outwardly from the central feed line as shown in Fig. 2. Each conveyer carries rollers 24 which contact with the articles and, whilst not interfering with their forward travel, tend to stretch them outwardly from their mid-line and so remove creases. To allow the passage of the carrier 13, 14 between the conveyers the upper pair are movable vertically, such movement also being controlled by the cam 31 associated with the reciprocating mechanism.

Title: Improvements in or relating to feed-water heating systems
Inventor: STARMER ROY
IPC: F22D11/06
Filed: 1961-10-06
Abstract: 1,044,832. Feedwater heating systems. RICHARDSONS, WESTGARTH & CO. Ltd. Oct. 4, 1962 [Oct. 6, 1961], No. 36037/61. Heading F4A. In a feedwater heating system in which exhaust steam from a turbine 10 is condensed in a condenser 12 and subsequently used as feedwater for a steam generator, steam at a higher pressure and temperature is bled from the turbine through a line 16 and part of this bled steam is led to an ejector 18 in which it is used to recompress a portion of the exhaust steam from the turbine. The resulting combined stream of steam at an intermediate pressure flows through a heat exchanger 20 to the condenser 12 heating the feedwater in so doing. The feedwater from the heat exchanger 20 is pumped to a further feedwater heater 22 in which steam bled from the turbine through line 16 effects further heating before flowing to the heat exchanger 20. In a modification (Fig. 2, not shown) a number of ejectors are used to compress the low-pressure steam to varying pressure levels, each of the ejectors being associated with a separate feed-water heater arranged in series with the other heaters with respect to the flow of feedwater. In an alternative arrangement the bled steam is used to compress the low pressure steam by means of a turbine-driven compressor instead of an ejector. The invention may be combined with the condensing system described in Specification 1,044,831.

Filed: 1946-12-06
Abstract: 640,247. Revolving barrel locks. GILJE, A. Dec. 6, 1946, No. 36155. Convention date, May 18, 1942. [Class 44] A safe lock comprises a guiding piece 2, Fig. 5, fixed to the inside of the safe door 1 and a horizontally slidable bolt carrier 3 which may be locked to the guide piece 2 by four spring-actuated pin tumblers 4 which are slidable in holes in the boltcarrier 3 and project into corresponding holes in the guide piece to engage with slidable pins 8. A barrel 12, provided with a row of holes for the pin tumblers, is rotatable about a cylindrical projection 6 on the guide 2, this barrel being locked to the guide by means of a second set of spring-pressed pin tumblers 15, Fig. 1. arranged displaced at an angle, preferably 90 degrees to those of the main lock. When the barrel is locked to the guide by means of the pins 15, the pins 8 of the main lock press against the front edge of the projection 6 so that access to the main lock from outside is prevented until the barrel is unlocked and rotated through the necessary angle. The pins 15, when projecting in locking position into the barrel hole row, engage pins 7, one of which has a recess into which a third set of pin tumblers 19, 20, substantially perpendicular to the other pin tumblers 4, 8, 7, 15 project, to prevent rotation of the barrel 12, even when pins 15 have been pressed back correctly. The key 17 has notches 18 in one of the pins to engage with the pins 19 when the key pins are pushed into the barrel holes. The pins 19, 20 are thereby pushed outwards against their springs until their contacting surfaces are flush with the slide face between the barrel 12 and the fixed member 16, so freeing the barrel for rotation, the barrel being provided with guide slots for stop screws to limit the rotation. The cover 5 of the bolt carrier 3 has attached to it a pin 9 which projects into a hole in the locking bolt 10. The bolt being slidable in guides, not shown, may be moved by an exterior handle when the bolt carrier 3 is not locked to the guiding-piece 2.
