Filed: 1976-02-03
Abstract: 1527111 Thermal regenerators BRITISH STEEL CORP 3 Feb 1976 [4 Feb 1975] 4748/75 Heading F4K Refractory brickwork with through passages therein and comprising the heat transfer material in a thermal regenerator is arranged as a plurality of sets 29 spaced apart one above another and each set is supported by individual support means at least one of which comprises pipes connected to a source of coolant (e.g. steam). In the arrangement shown in which each set comprises two layers 30 separated by spacing means 31, the individual support means for the upper set comprises horizontal portions of pipes 20. For the remaining sets the support means comprises pipes 24 which are supported along the central axis of the regenerator on annular platforms 25 secured to rings 26 which encircle as a column, vertical portions of the pipes 20. Both the pipes 20 and 24 ,which may have an external covering of refractory material, may be cooled by steam which is subsequently used for electric power generation. Intermediate support structures 27 comprising flat spirals are positioned between the brickwork sets and the support means 20, 24. The regenerator shown comprises a hot-blast stove with a combustion chamber 13 and reversing valves 14, 19 which operate together to direct alternately through the mass, combustion gases from the chamber 13 which pass ultimately to a stack 17, and combustion air from an inlet 18 which after heating is directed at 21 to a blast furnace 16 is a temperature sensor acting to initiate reversal of the valves 14, 19. Waste heat boilers (not shown) may be positioned in the stack 17.

Title: Improvements in and relating to gas-blast electric switches
IPC: H01H33/91
Filed: 1935-02-14
Abstract: 451,431. Gas-blast switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Feb. 14, 1935, No. 4805. Convention date, Feb. 14, 1934. Addition to 451,233. [Class 38 (v)] In a gas - blast switch as claimed in the parent Specification and in which the compressed gas is produced by the operation of the circuitbreaker, the contacts are arranged, during the initial stage of the switching-off movement, to remain in touch and to move together over a portion of the break path. In the arrangement shown, the nozzle b is carried by a member u slidably mounted, under the control of a spring r, on the end of the tube c surrounding the contact a. The gas blast is produced by a piston x carried by the tube c. When the switch opens, the tube c, nozzle b and contact a are moved downwardly, and the contact d follows the movement, under the action of a spring y, until its further movement is prevented by an adjustable stop z. The tube c continues its downward movement, with separation of the contacts and shortly afterwards the nozzle b is raised either by the air pressure beneath it or by the engagement of a lever s with a cam t, to open the air passage through the nozzle, whereupon the air blast blows out the arc.

Abstract: 1,170,967. Reservoir marking instruments. STANDARDGRAPH FILLER & FIEBIG G.m.b.H. 2 Feb., 1967 [4 Feb., 1966], No. 5029/67. Heading A4K. [Also in Division B6] A porous writing tip for a reservoir pen is formed by enclosing a cluster of intertwined metal fibres in an adherent liquidproof sheath. Stainless steel wires 1 are enclosed in a sheath 2 of nickel, deposited electrolytically. The nickel may be overcoated with hard chrome, to resist wear. The end 3 is ground to a point. The sheath may alternatively be formed by vapour deposition, on immersing the wires in a liquid solder and then passing them through a die. In another form (Fig. 5, not shown), the wires are placed in a stainless steel tube which is drawn through a die to reduce its diameter and cause it to grip the wires. The wires may alternatively be gripped by closing the seam of a half open free-rolled metal tube. An outer covering of plastics material may be formed by extrusion to produce a larger diameter writing tip, or by immersing the wires in a lacquer adhesive and withdrawing them through a die.

Title: Improvements in Fire Extinguishers.
Inventor: DEHN FRANK BERNHARD
IPC: A62C13/00
Filed: 1916-04-13
Abstract: 101,925. Dehn, F. B., (Pyrene Manufacturing Co.). April 13, 1916. Extincteurs or chemical fire-extinguishers.- Compartments 2, 3, respectively for the fireextinguishing fluid and for the generation of gas by suitable chemicals, are separated by a partition 4 containing a cup 5, the entry into which of the gas tube 12 is protected by a oneway valve 14, 15 and a small-mesh screen 13. When the extinguisher is inverted, a stopper 22 falls away from an acidcontaining bottle 21, standing normally upon flanges on the base of the cup and held on inversion by a wire screen or cage 23, whereupon the reaction takes place, with generation of gas passing through apertures or conduits 25, the position of which precludes the trapping of gas with consequent expulsion of chemicals into the fire-extinguishing liquid chamber. The accumulation of gas in the chamber 3 forces the liquid out through a screen 36 and hose 35. The gas. generating chamber is removable for recharging, irrespective of the amount of liquid present in the lower chamber.

When condensation appears on the window, the resistance between the electrodes 3, 4 decreases, causing the electronic switching circuit to connect the heater to the vehicle power supply. One of the electrodes is curved so that the spacing of the electrodes is reduced in the centre of the window, thereby increasing the sensitivity of the system to condensation in the central area of the window. The heater and the electrodes are preferably formed by material deposition on the window.
