Title: Electronic timing device
Inventor: LOVETT VERNON
IPC: G04F10/00
Filed: 1958-05-06
Abstract: 856,844. Time interval measuring. H. & B. PRECISION ENGINEERS Ltd. May 12, 1959 [May 6, 1958], No. 14465/58. Class 37 Apparatus for timing a vehicle or competitor over a fixed distance comprises at the beginning of the distance a pressure sensitive shoe 11, operated to close hydraulic switch 12 to energise relay 8 which holds over one pair of contacts and connects timebase generator 2 to electronic decade counter tube 3 registering hundredth second intervals, which at every tenth count operates similar counter tube 4 registering tenth second intervals. At every tenth count the latter impulses a cold cathode tube 6 to strike and magnetically operate a mechanical counter 5 constructed to count seconds on its first pair of digits and minutes on its remaining pair. At the end of the distance a photocell 17 whose illumination is obscured by the vehicle or competitor pulses a radio signal from transmitter 16 producing a further pulse in receiver 13 to operate relay 14, which opens contacts 15 to release relay 8 and disconnect the timebase so that the electronic counters and the mechanical counter register the elapsed time. Switches 9, 10 may be respectively operated for manual starting and stopping of the apparatus, and switch 18 may be opened to reset the counter. The apparatus is energised by direct voltages from alternating current power supply 7, and the pressure sensitive shoe switch is replaceable by a photocell arrangement or vice versa for operation of the appropriate relays. The signals starting the apparatus may be transmitted to the timing apparatus over a similar transmitter-receiver link.

Filed: 1951-06-20
Abstract: 703,939. Shoe sole attaching press. MARASCO, H. E. June 20, 1951, No. 14582/51. Class 17(1) A shoe sole attaching press of the turret type comprises a stationary supporting column 10 and a vertically disposed cylinder 14 rotatably mounted thereon and carrying a plurality of radially arranged presser units. This cylinder constitutes a reservoir for the supply of pressure air or other fluid. It carries at its lower end a six-lever Geneva disc 17 and is driven intermittently by a mutilated disc 18 pinned to the upper end of a shaft 19 driven at constant speed through a one-revolution clutch 25 by a motor 24 on the bottom of the column 10. Depression of the operating handle 29 causes the clutch to be tripped by a pivoted dog 26 and the cylinder 14 is moved through 60 degrees. Boxes 34. which may be adjustable in slots 33 on angularly disposed base plates 32, are provided with flanged side walls and inflatable pads so as to conform outer soles placed on lasted shoe upper pressed against the pads when these are inflated. Inflation and deflation of the pads is produced by operation of an arm 41 which controls a sliding sleeve valve 40 and an exhaust port 49 and is moved to and held in its open position by a cam 43 on the top 12 of the machine frame and is engaged by a roller 42 on the arm 41. The arm 41 may also be operated manually at any time to close the valve or it may be operated at the final station of the machine by a treadle 46. The pressure fluid in the cylinder 14 is maintained by a connection to a swivel joint 48 from any convenient source such as an air compressor. Arms 54 carrying pivoted toe and heel posts 55, 56 respectively are vertically adjustable on the cylinder 14 and bear upon the forepart and cone of a last within the shoe and support it against the thrust of-the inflated pad.

Patent GB-737295-A (GB)
Title: Improvements in or relating to the production of alkali metal and ammonium thiosulphates in anhydrous or lower hydrate form
Inventor: DIMSDALE WILFRED HAMPDEN
IPC: C01B17/64
Filed: 1953-05-26
Abstract: Anhydrous alkali metal and ammonium thiosulphate are prepared by adding an aqueous solution of the thiosulphate to a substantial volume of a water-miscible organic liquid which is non-solvent for the thiosulphate and which does not form an azeotrope with water and thereafter recovering the crystallized anhydrous thiosulphate. Alternatively the thiosulphate hydrate may be added to the organic liquid which is maintained above the melting-point of the hydrate when, on agitation, a lower hydrate is formed which after separation can be rendered anhydrous. Methanol is the preferred liquid and after separation of the thiosulphate the methanol can be distilled off and reused. Examples illustrate the production of anhydrous ammonium and sodium thiosulphates by adding solutions thereof to methanol maintained at 20 DEG  and 60 DEG  C. respectively.  The separated thiosulphate may be heated to drive off residual methanol.  A further example illustrates the addition of sodium thiosulphate pentahydrate to methanol maintained at 60 DEG  C., and subsequently cooling to 30 DEG  C. to deposit the trihydrated thiosulphate.  On vacuum drying at 50 DEG  C. an anhydrous sodium thiosulphate is formed.

Title: Improvements in the manufacture of cellulose
IPC: D21C3/16
Filed: 1934-05-16
Abstract: To prevent deterioration of the cellulose during the extraction of wood, wood pulps &c. with nitric acid, the latter contains a substance resulting from the treatment of a lignocellulose material with nitric acid.  The acid may be obtained by heating a nitric acid solution with wood substance, and then bringing the acid to the desired concentration by the addition of water or acid; and the acid employed for the extraction may be used repeatedly after suitable adjustment of its concentration.  In a p  modification, there is added to chemical wood pulp to be refined, finely divided raw wood or mechanical pulp, and the whole treated with nitric acid solution. The acid treatment may be followed by a treatment with alkali, in particular with dilute alkali at an elevated temperature, and such alkali solution may also contain a substance resulting from the treatment of a lignocellulosic material with alkali as described in Specification 438,434.  The alkali treatment may be in two stages, preferably first with dilute alkali at elevated temperatures and optionally under pressure, and then with cold, stronger alkali.  The products are suitable for the preparation of cellulose esters and ethers and for the manufacture of paper.  Specifications 263,938, 312,098, [both in Class 2 (ii)], and 438,435, also are referred to.

Title: Improvements in or relating to telephone systems
IPC: H04M7/06
Filed: 1939-05-19
Abstract: 529,448. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. May 19, 1939, No. 15010. [Class 40 (iv)] In a non-register-translator system in which two or more satellites each of which includes several thousands of lines share a ten thousands digit, the number of digits dialled is kept to the minimum without running separate junction groups from the main exchange for each of the thousands in the satellites by providing a discriminator set DRS, Fig. 2, which switches the call to the proper satellite in accordance with the thousands digit and subsequently, with the help of an impulse regenerator of the type described in Specification 458,095, sends that and subsequent digits thereto. Metering in accordance with the junction selected is controlled from the discriminator set. Circuit arrangements. Line relay A repeats the thousands digit to magnet JHM of switch JH and to receiving magnet RM of the regenerator. At the end of the digit, dialling relay C releases marking magnet MM which it previously engaged and ON pulls up and locks. At the same time a circuit is made over the discriminating wipers 8 of switch JH whereby HA pulls up with or without the wiper changing relay HB and the switch is sent home. The removal of a short circuit over wiper JH7 now allows JHR to pull up and lock whereupon JH hunts like a line switch under control of K. The latter in addition to switching through energizes the regenerator sending magnet SM and releases P to initiate the sending of the first of the stored digits. IP pulls up on the relapse of P to ensure a pause between digits. When all the digits have been sent ON is released and extends the junction back to the supervisory relays I, D. The distant line relays are held during the switch-over by resistance YB. According to the Provisional Specification discrimination may be controlled by a separate counting chain instead of by a numerical operation of JH. If an unobtainable thousands digit is dialled relay NB is operated over JH8 and sends back NU tone. If the switch JH finds all trunks busy NB is operated over JH5 or JH6 and since HA is operated sends back busy tone. Metering. On the response of supervisory relay D, S and Z relays DA, DB connect metering relay MP to the appropriate pulse lead 11 or 12 for a cycle.
