Patent GB-131883-A (GB)
IPC: B25B1/10
Abstract: 131,883. Rocher, M. Aug. 29, 1918, [Convention date]. Vices.-In a vice of the kind in which the movable jaw is initially adjustable by a screw, the head of which is fitted in a block which may be rapidly displaced to effect the gripping of the work by a cam engaging the fixed jaw, the cam is provided with an integral shoulder adapted to co-operate with a stop on the vice frame to effect instantaneous release of the work. As shown, the movable jaw B is initially adjusted by a screw E and hand-wheel Q. The screw E engages a. nut D in the jaw B, and its head rotates in a block J to which is pivoted a cam N which co-operates with a stop L on the fixed jaw H to slide the block J in one direction to grip the work, and is formed with a shoulder to co-operate with a stop bar M on the vice frame A to slide the block J in the other direction to release the work. By removing the cam and securing the block J to the frame A, and replacing the hand-wheel Q by a hand-lever, the vice may be used as an ordinary screw vice. To grip tapered work the jaw B may be replaced by a jaw holding a pivoted jaw face. The Specification as open to inspection under Sect. 91 (3) (a) states also that the vice may be converted into " multiple apparatus " by " substituting for the jaw-chucks provided jaws of other suitable profiles," and the vice in this case may be used for milling, drilling, planing, &c. This subject-matter does not appear in the Specification as accepted.

Title: Battery Charging Systems
Inventor: WRIGHT MAURICE JAMES
IPC: H02J7/14

Abstract: 1,174,897. Supply systems for road vehicles. JOSEPH LUCAS (INDUSTRIES) Ltd. 8 March, 1967 [25 March, 1966], No. 13261/66. Heading H2H. [Also in Division G3] A battery-charging system for a road vehicle is provided with a warning lamp 20 controlled by a transistor 19 responsive, via circuit members 17, 18, 22, 23, to the output of the vehicle generator, the arrangement being such that the lamp is extinguished when the generator is producing an output and the lamp is illuminated when the generator is not producing an output. With no output, closure of a switch 16 (e.g. the ignition switch of the vehicle) charges a capacitor 18 to make transistor 19 conductive and so illuminate the lamp. A terminal 23 is connected so as to be responsive to the generator output which, when present, causes the potential of terminal 23 to vary between positive and negative battery potential, this action in turn causing the capacitor 18 to discharge and charge. However the time constants of the circuit are so chosen that capacitor 18 cannot charge sufficiently to make the transistor 19 conductive and hence the lamp 20 is extinguished when the generator is producing an output. The generator may be an alternator/ rectifier unit or a D.C. generator. In the former case, the terminal 23 is connected to a phase point or to the star point of the alternator. Other connections are possible, providing that the potential at the junction of members 17, 18 is never allowed to become sufficiently positive to turn on the transistor 19. For example the terminal could be connected to the field winding of the generator. In a modification, Fig. 2 (not shown), the circuit comprising members 19, 20, 21 is connected directly across the terminals 13, 14, members 17, 18, 22 are omitted and the transistor 19 is controlled by a circuit comprising a second transistor and two resistors. In this modification there is no time delay effect.

Class 64(i) A gas heater or other heat transfer apparatus comprises a fluent gas-pervious mass of pellets flowing downwardly under gravity through a plurality of upper zones 10 and throat conduits 12 into an adjacent lower chamber 11 with a bottom outlet 14 for pellets, the conduits 12 being symmetrically arranged relatively to the outlet, and the upper zones 10 containing equal quantities of pellets and having equal crosssectional areas and receiving from a common source 13 equal streams of gas, which comes into direct contact with the pellet mass. In the form shown, the zones are in separate chambers symmetrically arranged around a combustion chamber 13 with a burner inlet at the top and radial passages 32 leading to the chambers 10. Pellets from the outlet 14 are carried by a bucket conveyer to a bin above the heater, and flow from the bin to the chambers 10 through conduits 20 the outlets of which are at the same level. In a modification, the plurality of upper zones are sectors of an annular chamber surrounding the upper part of a combustion chamber with burners at the bottom, and are connected by a ring of conduits to the lower chamber, which may be a heat exchange chamber or an intermediate chamber leading to the heat exchange chamber.

A rocket firing device, e.g. for firing lines, comprises a firing tube 10 the rear end of which is in communication with a firing device 12 through a firing duct 32 formed in a holder tube 11. The firing device 12 houses and explodes a cartridge, hot gases from which explosion pass through the firing duct 32 to ignite the rocket propellant charge. The gas stream from the propellant charge is deflected forwardly of the rocket firing device. To this end, a deflector member 18 is provided, the member 18 preferably having apertures 21 in its circumference and a ring-shaped holder 19 by which the rear of the rocket 22 is centred in the device. The forward end of the device is provided with a guide frame 28 to which a firing line may be connected, the rocket being centred therein by spring elements 35 and a holding means 36. The holding means 36 also connects the guide frame to the rocket. The annular space about the centred rocket forms a duct for the forward escape of the propellant gases.

Abstract: 623,847. Conveyers. FORD, E. May 19, 1947, Nos. 13361 and 20386. [Class 78 (i)] In a conveyer comprising one or more receptacles suspended from an endless chain or the like, the swinging motion of the receptacles is reduced by a ratchet and pawl or other mechanism restraining the pivot between each receptacle and the chain. The dough-carrying tray 12 shown is riveted by its vertical wall 11 to a bar 5 rotatably mounted on an extension 3 of one of the rivets 2 of a sprocket-driven chain 1. Pawls 6 pivoted to the bar 5 are urged by springs 9 against the teeth of a ratchet wheel 4 keyed to the rivet extension 3. Thus when the tray is passing round the chain sprockets its weight causes the pawls 6 to ride over the ratchet teeth so that the bar 5 remains vertical, but swinging of the tray in the opposite sense relatively to the chain is limited to the extent of one ratchet tooth. In an alternative construction where the chain may be driven in either direction, the ratchet wheel and pawls are replaced by two discs engaging each other by shallow serrations on their faces and spring-urged together, one of the discs being secured against rotation relatively to the chain and the other being fixed to the bar 5.

Abstract: 290,174. I. G. Farbenindustrie Akt.- Ges. May 6, 1927, [Convention date]. Titanium dioxide; double salts. - Titanium cres are treated with sulphuric acid and the titanium then brought into solution as a double salt by treatment with an alkali salt such as sodium, potassium, or ammonium sulphate. Preferably, the solution step is effected under heat and the proportions so chosen that a saturated solution is obtained, from which, after filtration, the double salt may be crystallized out. The crystals may be washed with a saturated solution of alkali sulphate or be re-crystallized from dilute sulphuric acid to free them from iron. From a solution in dilute surphuric acid or a suspension in water of the double salt, titanic acid may be obtained by hydrolysis, if desired under pressure. The mother-liquor containing sulphuric acid and alkali sulphate may be used in the solution step of the process.
