Abstract: 390,183. Totalizators. FISHBURN, J. E., 39, St. James' Street, London, and DEGEN, A. A. C., Peveril, Headstone Gardens, Harrow, Middlesex. Sept. 25, 1931, No. 26798. [Class 106 (i).] In a totalizator system in which the ticket machines are connected to the registering equipment over common wires, one for each competitor, an automatically rotated switch device applies a test potential to each machine in succession, which, when applied to a machine at which a bet is set up is extended over the starting circuit of the machine and a competitor line to the appropriate registering circuit, and is maintained until the bet is registered. At each ticket machine A, B .. are contacts k for competitors 1, 2 .. 8 connected through contacts rp1, .. rp8 to the competitor lines CWW1 .., CWW8 which lead to the corresponding competitor counter magnets W and to the pool counter magnet TW. Control lines E1, E2, .. from the different machines are connected seriatim to the bank of an assigner RLS which is normally stepped by interaction between its drive magnet DM and a relay H. To set up a win bet at machine A, for example, which may be as described in Specification 330,264, [Class 106 (i), Calculating &c.], a competitor key k is depressed causing closure of master contacts CB1, CB2. When the wiper SW of assigner RLS reaches the position shown a circuit is made over contact f2, SW, line E1, contacts CB1, relay R, contact k of the competitor 6 for example, rp6, line CWW6 to the corresponding competitor registering magnet W in series with the pool magnet TW. At " early operating " contacts tw1, w1 relays H and WG are energized, contacts h1, wg1, thereof maintaining the drive magnet DM energized. When the magnets W, TW have fully operated " late operating " contacts w2, tw2 close to energize a release relay F which locks over f1, h2 and at f2 breaks the registering circuit whereupon magnets W and TW release, in turn releasing relays WG and H. Relay F then releases to deenergize DM and the assigner RLS steps as before. Place betting. A key RP3 at a ticketissuing machine is depressed energizing a relay RP which at change-over contacts rqr1, .. rp8 connects the lines 1, .. 8 to the place lines CPW1, .. CPW8 leading to the place competitor and pool counter magnets P and TP operated similarly to W and TW. Ticket-machine operations. When the registering circuit is made over line E1 relay R energizes, locks by way of contacts r1, CB2, and, at r2, energizes the ticket-issuing start magnet SM the competitor key and contacts CB1, CB2 being reset during the ticket-issuing operation. Precautionary arrangements. Switches S are provided in the competitor lines to isolate competitor counters corresponding to non-runners. Secondary relays X, XX and Y, YY are provided to operate in parallel with the pool counter magnets TW and TP respectively contacts x1, yl, xx1, yy1 in parallel with tw1, tp1 ensuring operation of relay H during bet registration. An alarm lamp AL, Fig. 2, is provided and illuminated if either of the secondary relays fail to operate.

Title: Non linear network
IPC: H03B28/00
Filed: 1973-08-21
Abstract: 1485116 Waveform changing SOLARTRON ELECTRONIC GROUP Ltd 21 Aug 1974 [21 Aug 1973] 39386/73 Heading H2F [Also in Divisions H3 and G4] A function generator converting a triangular wave to sine wave form comprises a non-linear circuit 62 consisting of first and second transistors 64, 66 disposed in parallel paths and first and second non-linear devices (e.g. Schottky diodes) 72, 74 connected between base and collector of respective transistors. In addition, further non-linear devices (e.g. further Schottky diodes) 82, 80 are disposed between base and emitter of respective transistors. The dynamic resistance of the network 62 is very small for large excursions of positive or negative current when one of the transistors 64, 66 is conducting, but relatively large at small currents where it corresponds to the value of resistances 70, 76, 78 in series. For intermediate currents, the resistance is determined by the diodes 72, 74, 80, 82 and the transfer characteristic between the output voltage at terminal 60 and the input current from collector circuit off approximates in shape to the cosine function between #/2. If a triangular wave is applied to the input, a sinusoidal output is obtained. The triangular wave is generated from a rectangular wave applied to the base of transistor 8. A transistor 18 is connected to act as a current mirror for transistor 8 and thereby provide a high source impedance for current pulses applied to a capacitor 28 which integrates them. A Darlington pair 32 provides a low impedance output the triangular wave appearing across capacitor 28. A feedback loop comprising capacitor 84, diode 88, amplifier 94 and resistor 104 is responsive to the peak value of the triangular signal appearing at emitter 36. This is compared with a reference signal V ref  in amplifier 94 which adjusts the gain of transistor 8 so as to maintain constant the said peak value. Since the diode 88 is temperature responsive, the peak value is reduced with increasing temperature and the drive voltage of network 62 correspondingly reduced. This has the effect of compensating for the temperature coefficient of the non-linear network.

Title: Process for the recovery of cobalt catalysts
IPC: C07C63/06
Filed: 1962-10-31
Abstract: Cobalt containing catalysts are recovered from liquors containing cobalt benzoate by interaction with a cation exchange resin at 10-90 DEG  C., treating the resin with strong acid, dividing the solution issuing from the resin into head and tail fractions containing cobalt, intermediate fractions having less than 5% of cobalt salt and central fractions having 5-10% cobalt salt and recovering the cobalt from the central fractions.  The starting liquor may be boiled with activated charcoal or a diatomaceous earth before interaction with the resin.  The resin may contain carboxyl or sulphuric acid groups and may be in the form of a column. Benzoic acid may be recovered from the treated starting liquor, e.g. by adding it to the product of the main oxidation reaction.  The cobalt impregnated resin may be washed with water at 70-80 DEG  C. prior to acid treatment and the washings added to the treated starting liquor for benzoic acid recovery.  Suitably acid elements are HCl, H2SO4 and any acid stronger than the resin.  The head and tail fractions are discarded and the intermediate fractions are used, with the addition of strong acid for regeneration of the resin with hydrogen ions in subsequent experiments.  The central fractions may be treated with an alkali metal salt of an organic acid to give a desired cobalt salt for catalysis.

Abstract: 925,390. Optical slit diaphragms. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. Nov. 17, 1961 [Nov. 22, 1960 (2)], No. 41278/61. Class 97 (1). A pair of jaws, defining a slit, are mounted on carriers each supported from a pair of cantilevered leaf springs which bias it into contact with guides so located that each carrier is movable in the plane of the slit and perpendicularly to the slit axis so as to alter the slit width. As shown, two slits 20, 21 are defined by jaws 16, 18 and 17, 19, the jaws 16 and 17 being mounted on a carrier 14 and the jaws 18 and 19 being mounted on a carrier 15. These carriers are connected by leaf springs 12, 13 to a pair of cantilevered leaf springs 6, 7 whereby they are pressed against guide rollers 22. A tension spring 24 biases the carriers so as to decrease the width of each slit, whereas increase in width is obtained by rotating a cam 31, e.g. in synchronism with wavelength variations, so as to operate a rocker arm 29 having rollers 25, 26 in contact with shoulders 27, 28 on the carriers. Rollers 23, turning about axes parallel with the plane of the slits, resist the turning movement on each carrier due to the biasing form of springs 6, 7 and reaction of the guide rollers being in spaced parallel planes. Specification 887,239 is referred to.
