Title: Improvements in or relating to fastener-separating apparatus
IPC: A43D71/00
Filed: 1952-08-02
Abstract: 730,593. Feeding tacks. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). July 31, 1953 [Aug. 2, 1952], No. 19617/52. Class 78 (1). A tack-feeding device comprises a raceway having a tack-feeding groove 40 (Fig. 7), a discharge passage 46, a separator 50 having a recess 70 and moving to receive a tack in the recess from the groove and to position it to be discharged by a discharge block 80 through said discharge passage 46. As shown, reciprocating separator 50 (Fig. 7) discharging from grooves 40, 42, carries in a slot therein the arm 72 pivoted at 76 and carrying said block 80 so that when cam 86 formed on arm 72 meets the tip of spring 88 said block 80 moves to eject the tack contained in .recess 70. The reciprocation of separator 50 is derived from the reciprocating tack nozzle 20 of a shoe lasting machine (Fig. 2), said nozzle 20 being secured to plate 112 carrying pivotally arm 120; and stud 127, which works in a slide in said arm 120, is carried by one arm 128 of a bellcrank lever pivoted at 124, the other arm 190 of which lies between and swings pairs of arms 192, 194. The ends of the latter embrace and reciprocate block 198 which in turn, through linkage 200, 84, reciprocates separator 50. This movement is transmitted with arm 120 urged against one of two end stops 152, 154 by the pressure spring- impelled plunger 136 and is secured thereat by spring-impelled arm 170 having tooth 172 engaging in alternate recesses 180, 182. The plunger 136 is connected by levers 138, 156, 158 to shift arm 166. The operator moves the latter and so swings over the plunger 136 which in turn so positions the separator 50 to discharge tacks from the other tack groove 42. The pair 'of arms 192, 194 are connected by spring 196 so that when a tack jams, one of the arms yields to stop the reciprocation of separator 50. In order that the tacks should be presented in overlapping formation down groove 40 (or 42) the groove is formed with a notch 310 (Fig. 10) which serves to so orientate the tacks.

Title: Improvements in and relating to regulating or tap changing mechanism for electric transformers
IPC: H01H9/00
Filed: 1939-07-06
Abstract: 535,372. Top changing switches for transformers. HACKBRIDGE ELECTRIC CONSTRUCTION CO., Ltd., MARSH, F. P., and RYCROFT, C. W. July 6, 1939, No. 19678. [Class 38 (v)] In a tap-changing switch for transformers operable by variations of voltage or by hand, the variations of voltage cause the timed operation one way or the other of an electrically-driven pump 5, 6 which pumps liquid into one of two cylinders 13 thereby raising a piston 15 against the action of a spring 20 and lifting a pawl into engagement with a ratchet wheel 23. When the pump stops, the piston 15 descends at a rate determined by a bleed hole 12 and rotates the ratchet wheel 23 through one step thereby oprating mercury switches controlled by cams on the shaft 19 of the wheel 23, and effecting the change from one tapping to the next. The ratchet wheel 23 is rotated in the reverse direction by the other pawl when the motor pumps liquid into the other cylinder. In the preferred circuit arrangement, Fig. 6 (not shown) the change in voltage causes the energization of one or other of two delayed action relays which cause the tilting of one or other of two mercury switches controlling a change-over switch such as described in Specification 535,373 which last switch operates the motor of the pump in one direction or the other. After the change-over switch and therefore the motor have operated for say half a second, they are de-energized and after say 2 seconds the relay itself is de-energized and thus brought back to its original position.

Title: Improvements in or relating to a device for measuring and recording pulse frequency
IPC: G01D9/10
Filed: 1961-06-01
Abstract: 967,367. Pulse recorders. TESLA, NARODNI PODNIK. June 1, 1961 [June 10, 1960], No. 19788/61. Heading G1J. In apparatus for measuring and recording the frequency of pulses, the pulses are supplied to a digital pulse counter P which is so arranged that it produces a mark on a record sheet S on receipt of the K-th pulse, the mark being made with a recording device R moving across the sheet S according to a law x = #(t), where t denotes time and x denotes the distance of the device R from a reference point on the track of the device R, so that the co-ordinate xf of a mark made on the sheet S at the arrival of the K-th pulse is xf =#(K/f) and is indicative of the frequency f. The apparatus may be arranged so that after the lapse of a predetermined period the counter P is reset to zero and switched over in such a manner that it produces a mark at the arrival of the K<1> pulse where K<1> is a predetermined fraction of K selected to enable two ranges of frequencies to be clearly recorded on different scales and after the resetting of the counter to zero, the movement of the device R may be stopped tor a period to avoid a gap between the two scales. In a practical embodiment, Fig. 2, a sleeve 5 is moved alternately to the left and to the right by rotation of a screw 2 having a left-hand and a right-hand thread engaged alternately by a spring urged pin 51 housed in a frame 52 fixed to the sleeve 5. The sleeve 5 carries a holder 6 for a recording device 1 and stops 8, 9 located at points a third and two-thirds of the path across the sheet S co-operate with a pin 7 spring-loaded into contact with steps on the sleeve 5. Initially holder 6 moves with sleeve 5 from right to left with pin 7 on the highest step so that in due course it engages stop 9 and prevents holder 6 moving further with sleeve 5 until their relative movement brings the pin 7 down on to the middle step free from stop 9. Holder 6 moves with sleeve 5 again until pin 7 engages the lower stop 8 where it is held until the relative movement brings the pin 7 over the lowest step free from stop 8. Holder 6 and sleeve 5 move to the left hand end and return to the right together with the pin 51 following the other thread of the screw 2. The holder 6 is stopped first and the sleeve continues until the pin 7 has climbed to the top step and movement is reversed. When the pin 7 touches either stop 8 or 9 electric contacts are made to zeroize the counter and switch a relay cicuit so that the K<1>-th pulse is counted instead of the K-th. In order to change the scale of recording over ranges varying within one power of ten, K = 10 K<1>.

Title: Improvements in or relating to the production of uranium tetrafluoride
Inventor: NAIRN JOHN SYME
IPC: C01G43/06
Filed: 1956-06-28
Abstract: A vaporous mixture of uranium hexafluoride and carbon tetrachloride comprising 2-4.5 mols. of carbon tetrachloride per mol. of uranium hexafluoride is heated at 150-400 DEG  C. to produce uranium tetrafluoride.  In the preferred procedure, streams of the reactants are separately preheated to at least 150 DEG  C. and passed through concentric tubes into one end of an inclined rotary tube of nickel-lined stainless steel heated by a furnace where they are mixed rapidly with the assistance of a deflector plate, and pass down the tube which is maintained at 285-310 DEG  C. over most of its length. The resultant solid progresses toward the lower end of the tube into a settling chamber from which it is periodically removed and blown with dry air at 300 DEG  C. to remove adsorbed vapours.  The vapours leaving the settling chamber have fine particles of tetrafluoride removed and are then cooled to 20 DEG  C. to condense out excess carbon tetrachloride and then scrubbed with caustic soda to remove chlorine.  The remaining vapours comprising fluoro-chloro-methanes are recovered by adsorption on charcoal and condensation at -20 DEG C. followed by fractional distillation.  The invention is stated to have particular application to the conversion to UF4 of UF6 enriched with respect to U235.  The Provisional Specification is not restricted to the above-mentioned proportions and mentions relative flow rates of 2-7.5 mols. of carbon tetrachloride to one of uranium hexafluoride; it is also stated that unless adequate residence time is provided in the tube, fluorides of intermediate composition tend to be formed.  Specification 801,382 is referred to.ALSO:Vapours consisting mainly of CCl3F and CCl2F2 with small amounts of CCIF3 are obtained after separation of dust, chlorine and carbon tetrachloride, in a process wherein a vaporous mixture of uranium tetrafluoride and carbon tetrachloride having a molar ratio of 1 : 2 to 1 : 4.5 is subjected to a temperature of 150-400 DEG  C.  The fluorocarbons may be recovered partly by adsorption on charcoal and partly by condensation at -20 DEG  C. followed by fractional distillation. Specification 801,382, [Group III], is referred to.

Abstract: 1,001,646. Radio navigation. WESTERN ELECTRIC CO. Inc. May 25, 1962, No. 20118/62. Heading H4D. [Also in Division G3] In a system for determining the relative distances of spaced aerials, the aerials radiate different double side-band (d.s.b.) suppressed carrier signals derived from a common carrier, one of the d.s.b. signals is demodulated to reconstitute the carrier wave, and the reconstituted carrier wave demodulates the other d.s.b. signals to produce outputs whose magnitudes correspond to the relative distance to the respective aerials. The invention is applied to the control of orientation of an earth satellite which carries the foregoing aerials. In one embodiment, the satellite, Fig. 1, carries dipoles 10, 12, 14 at the vertices of a triangle 16 the plane of which is to be maintained normal to the line-of-sight 18 to a ground control station; each dipole is excited by a different d.s.b. signal, derived from a common carrier generated by R.F. oscillator 20, and generated in respective balances modulators fed with L.F. signals of frequencies f 1 , f 2 , f 3 . At the ground station, Fig. 2, the satellite's radiations are received by aerial 34 and passed to mixers 38, 40, the suppressed carrier being reconstituted at oscillator 42 controlled in accordance with a synchronous detection method described in Proc. I.R.E., December, 1956, pages 1713 et seq. The reconstituted carrier demodulates the sidebands f 2 , f3 to yield D.C. error signals corresponding to carrier phase differences from aerials 10 and 12, and 10 and 14; the error signals are utilized to control orthogonal motors 86, 88, Fig. 1. Each motor derives a flywheel; or the motor armatures are weighted. In a second embodiment, in order to increase accuracy without ambiguity, the satellite carries two systems of aerials, Fig. 3 (not shown) and at the ground station corresponding error signals are combined, Fig. 4 (not shown).
