Patent GB-422200-A (GB)
Title: An improved method of electric signalling
IPC: H04Q3/42
Filed: 1933-07-04
Abstract: 422,200. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, both in London. July 4, 1933, No. 18955. [Class 40 (iv)] In a register-controller system, the transient cessation of current in the out-impulsing circuit which occurs when the switching relay of a selector operates is utilized as a signal to initiate transmission of the next digit, and brings about a momentary release of highspeed relay such as that described in Specification 405,436, [Group XXXVII]. In the case of the final selector the transient is incidental on the operation of the change-over relay. The invention is described with reference to the register-controller of Specification 411,462, which is shown in skeleton with the added parts in dotted lines. The standard intertrain pause is measured by the stepping of the sending switch S from position 18 to normal under the control of impulse springs IS 1. The high-speed relay VA energizes in the outimpulsing circuit when a short-circuit is removed by the operation of SZ at the end of a train and closes a charging circuit for a condenser K. On the momentary release of VA, a second high-speed relay VB pulls up due to the discharge of the condenser and connects up VC, which disconnects SZ while maintaining the impulse springs IS2 short-circuited, and causes the sending switch S to self-drive rapidly to normal, whereupon VC falls back and allows the next digit to be transmitted. The digit control switch CS is advanced by an impulse due to the operation and release of VC. Alternatively the receipt of the signal may bring into operation a second sending switch. Instead of employing common impulse springs IS1, 2, each register-controller may be provided with an individual impulse generating device of the kind described in Specification 334,516, [Class 40 (iv)], comprising cyclically operating relays shunted by condensers, the capacities of which may be changed by suitable cross-connections to vary the rate of impulsing for different trains.

Title: Liquid settling tanks
IPC: C02F1/52
Filed: 1974-04-30
Abstract: 1445301 Settling tank R P MOORE 30 April 1974 [11 May 1973] 18976/74 Heading BID A flat based circular settling tank comprises liquid recirculating means whereby liquid may be pumped from either a pipe 74 or pipe 76 to fixed nozzles 72 or rotary nozzles 26 to maintain a sludge blanket suspended above the floor of the tank, and a sludge sump 52 into which sludge from the blanket overflows. An inlet (40 Figs. 1 and 3 not shown) on wall 14 comprises a unit for mixing liquid with floc forming chemicals and leads through wall 14 to a downwardly inclined tangential nozzle. Nozzles 26 wash settled solids across the tank floor to sump 46 and rotation of the nozzles is induced by additional tangential nozzles at the free ends of nozzle arms 24. Baffles 34 on tank wall 14 deflect rotating liquid downwardly. Clarified liquid overflows weir 16. Sludge sump and tank floor have interconnected sludge wells 62 and 46 from which sludge is removed either by manual control of valve 68 or automatically using sludge level sensor 70 to actuate pump 50. A rotary scraper 66 traverses the sump floor.

Title: An improved electric switch
IPC: H01H21/42
Filed: 1922-07-11
Abstract: 197,867. McDowell, J. B. July 11, 1922. Switches, quick-action; covers. - In quickaction switches of the dead-centre type, the movable contacts 24 - - 27 are secured to a carrier 42, loose on the main shaft 36 and actuated by a member 37 secured to the shaft and engaging through teeth an arm 50 pivoted at 52. The arm carries a pin 53 in a slot 51, and between the pin and a part 41 of the carrier 42 is stretched a spring 57, which keeps the pin in engagement with a guide 54 attached to the lid 20. The part 41 of the carrier works in a slot in a guide 47, also attached to the lid, and by engaging a projection 58 on the switch wall, prevents the lid being lifted when the switch is on. To operate, the shaft 36 and member 37 are rotated, whereupon a lug 39 engages the part 41 and rotates it. The arm 50 also is rotated to tension the spring 57, which, after the initial movement, rapidly completes the action. The contact carrier 42 has a depending part 43 to which is secured an insulating plate 28 on which the movable contacts are mounted. As shown in Fig. 3, the movable contacts are rotated in a clockwise direction to close the circuit, the dotted lines 29, 30 being inter-connecting leads.

Filed: 1951-08-20
Abstract: In an Oxo synthesis at 200-450 DEG  F. and 2500-3500 p.s.i.g there is simultaneously fed to the carbonylation zone a lower boiling olefine or olefines of 2 to 5 carbon atoms per mol. together with a higher boiling liquid olefine containing at least 6, preferably 7-20, carbon atoms per mol., the latter acting as a solvent for the lower boiling olefines, the lower and higher boiling olefines being in the reaction zone for the same length of time.  Higher boiling olefines mentioned are a C12 polypropylene, a C7 fraction from propylene butylene polymerization and C12, C13 or C14 polymer olefines.  Lower olefine mentioned are propylene, normal or isobutylenes and amylenes.  Usual conditions of synthesis are observed and in an illustration a C12 polypropylene polymer cut of B.R. about 350-425 DEG  F. containing 1-3 per cent of a cobalt soap together with propylene is treated with H2 and CO in a ratio of 0.5-2 mols. of H2 per vol. of CO at about 275-450 DEG  F. and 2500-3500 p.s.i.g., the reaction products being passed to a catalyst removal zone where cobalt is deposited by treatment at about 200-400 DEG  F. with stripping by H2 at 15-200 p.s.i.g. and the liquid products are hydrogenated at about 300-500 DEG  F. and 2500-4500 p.s.i.g. in the presence of the usual catalyst to yield a mixture containing normal and isobutyl alcohols and C13 alcohols which are recovered by fractional distillation.  Desirably 2-50 per cent of water is present in the primary reactor.  In an example, propylene and isobutylene are treated in a heptene fraction from propylene butylene polymerization at 350 DEG  F. and 2800 p.s.i.g. with a H2/CO volume ratio of 1/1 in the presence of cobalt oleate and water, the final hydrogenation occurring in the presence of a sulphactive molybdenum sulphide catalyst and water.

Abstract: 1,036,900. Optical apparatus. I. D. MARTIN. Aug. 5, 1964 [May 18,1963], No. 19839/63. Heading G2J. [Also in Division F4] A lamp for producing coloured light comprises a housing 10 (Fig 1, not shown) containing a source of light 14 and at least two plane and spaced apart light filters 16 mounted within the housing for rotation in a horizontal plane about a common vertical axis. A motor 20 mounted within the housing drives the filters through rotatable members 22, 23 in driving engagement with the outer peripheries of the respective filters. The members 22, 23 are made of resilient material, e.g. rubber, and are so constructed that the filters are rotated, either intermittently or continuously, at different, but substantially constant, mean rotational speeds. To achieve this the members are formed with cylindrical surfaces of different diameter, or alternatively the surfaces are of the same diameter but one has discontinuities 24 (Fig. 3, not shown). The filters are mounted in three rotatable nylon bearing members 17 spaced around their outer peripheries, and each filter is subdivided into three equal sector-shaped portions which are differently coloured. The light bulb 14 is mounted in a reflector 15 to pass light through the superimposed filters, so that as each sector passes in turn over the bulb a succession of changing hues is obtained.
