Void [Abridged as open to inspection under Sect. 91 of the Acts, July 7, 1932]. [Class 38 (v).] In an "expansion " switch the contact - pin is withdrawn from the fixed contact through a number of liquid - filled pressure-developing chambers in series so that extinguishing liquid is forced into the arc both towards the fixed contact and towards the moving contactpin. In the arrangement shown in Fig. 1, one additional liquid filled expansion chamber d is employed depending into the main chamber a and formed with orifices for the passage of the pin contact c into engagement with the fixed contact b. When the pin is withdrawn, the arc vaporizes the liquid, for example, water, in its neighbourhood and extinguishing medium is forced from the chamber d towards both ends of the arc, and, at the upper end, into the condensation space y. Two auxiliary pressure chambers d, one above the other, may be used and a space may be left between them communicating with the main chamber by means of lateral openings n, Fig. 3.

Abstract: 1,046,296. Crimping pliers. D. A. VANOORT. May 8, 1964 [May 23, 1963], No. 19316/64. Heading B4W. Pliers for crimping a tubular connector on to a wire comprise a crimping head 20 which includes a central die carrier 50 having angularly spaced, substantially radial die guiding passages 54 extending outwardly from a concentric central bore 56 which is adapted to receive the connector to be crimped, crimping dies 62 being slidably mounted in the passages 54 and having outwardly projecting ends actuated by an outer camming head surrounding the die carrier and rotatable in relation thereto. The head comprises four interleaved laminations 21-24 having registering, central openings laminations 21, 23 being connected to the handle 30 of the pliers and laminations 22, 24 being connected to the handle 32. In operation the pairs of laminates 21, 23; 22, 24 are relatively rotatable in opposite directions. The laminations have openings 80 which accommodate the die heads 70, the openings in the pair of laminations 22, 24 having camming faces 82 which act on the die head faces 74 whereas the pair of laminations 21, 23 have camming faces 83 which act on the die faces 72 in a circumferential direction opposite to that of the cam faces of the pair 22, 24 on the die face 74 so that on closing the handles 30, 32 the dies are forced radially inwards. On opening movement oppositely acting cam faces 90, 91 force the dies out. A pawl and ratchet mechanism 110, 114 prevent the tool from being operated in either direction until the movement in the opposite direction is completed. In a modification, Fig. 7 (not shown) the die carrier is provided with an adapter ferrule 130 for centring an enlarged connector part. In another modification, Fig. 13 (not shown), the axial portion of the die carrier is a separate member 503 which is rotatably adjustable and carries a flange 504 provided with seating surfaces for the dies at different radial distances from the die carrier axis.

Abstract: 1,214,771. Fluidic circuits. CORNING GLASS WORKS. 16 April, 1969 [23 April, 1968], No. 19379/69. Heading G4P. A fluidic circuit having n control inputs gives an output dependent on the number of inputs energized. In a first embodiment, Fig. 1, signals on control inputs C of monostables 12, 14, 16 switch jet P from output B to output A. Outputs B are combined at input C of bi-stable 18 and outputs A are combined at D, so that bi-stable 18 gives an output B only when there are less than two control signals present simultaneously. By replacing monostables 12, 14, 16 by bi-stables similar operation occurs in response to sequential input signals. Bi-stable 18 may be replaced by a proportional amplifier, giving an output proportional to the ratio of the number of energized to unenergized control inputs. In the latter modification n may be even.

IPC: H01J19/00
Filed: 1957-06-20
Abstract: A metal is painted with an aluminium paint consisting of aluminium powder of high leafing value suspended in a liquid medium and binder e.g. polymethyl methacrylate solution, allowed to dry and heated to a temperature not exceeding 400 DEG C. to remove the binder, and thereafter heated under non-oxidising conditions to a temperature sufficiently high to cause the aluminium to react with the basis metal and produce a black intermetallic surface layer.

Abstract: 1454794 Detecting fluid level electrically AUTOMOTIVE PRODUCTS Ltd 21 Feb 1974 [25 April 1973] 19602/73 Heading G1N A fluid level warning device, wherein a selfheated temperature-sensitive resistance senses a difference in thermal conductivity between the fluid and air, comprises an element of semiconductor material having a negative and a positive thermal coefficient of resistivity respectively above and below a critical temperature, one face of the element being in thermal and electrical contact with a container provided therefor to which a first electrical connection is made, another face of the element having a second connection attached thereto. A doped Ge or Si chip 1 is attached by one face to the inner end 2 of a metallic can 3 held by a plastics holder 8 screwed into the wall 10 of a hydraulic reservoir of a motor vehicle. Electrical connections to the chip are by leads 5 and 6 passing through a seal 4 and attached respectively to the interior of the can 3 and to another face of the chip 1. An electric supply is applied by an ignition switch 14 to a lamp 13 in series with the chip 1, and the lead 5 is earthed to the vehicle chassis. The heat generated by electric current in the chip 1 is quickly dissipated if fluid 11 is present, so that the temperature of the chip 1 does not rise high enough to cause a fall in resistance sufficient to light the lamp 13. If the fluid 11 gives way to air of lower thermal conductivity, the chip 1 now heats to above the critical temperature, whereupon its resistance falls and thermal runaway ensues, until an equilibrium is reached wherein most of the supply voltage is dropped across the lamp 13. In very cold weather the change from n.t.c. to p.t.c. below the critical temperature avoids a highresistance condition wherein the chip 1 might fail to draw sufficient current to generate the heat  necessary to begin the thermal runaway in the presence of air.

Abstract: 122,169. Barrett Co., (Assignees of Downs, C. R.). Jan. 5, 1918, [Convention date]. Sulphonic acids.-The sulphonation of benzene is effected under reduced pressure in order to remove the water formed and thereby prevent dilution of the sulphonating acid. Preferably, the benzene is continuously added to the acid and brought into intimate contact therewith, any excess of benzene passing off with the water being recovered. The conditions may be adjusted so as to prcduce benzene mono- or di-sulphonic acids ; appropriate temperatures and pressures are specified. Using the apparatus shown, two or more jacketed sulphonators 1, 2 are charged with sulphuric acid and benzene (liquid or vapour) is led in by pipe 5; the tops of the sulphonators are connected by a pipe 8 to a vacuum pump 12 and condenser 13; the pipes 5, 8 are connected by a pipe 11. Supply pipes 22, 24, and draw-off pipes 23, 25, also are provided. By manipulation of the valves on the several pipes, the sulphonators may be worked in parallel or in series. A partially sulphonated mixture of benzene,' its monosulphonic acid, sulphuric acid, and water, may be heated under reduced pressure as described to remove the water and complete the sulphonation. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the sulphonation of other hydrocarbons and their derivatives in the manner described above. This subject-matter does not appear in the Specification as accepted.
