A thermocouple, intended particularly for use in ignition safety devices for gas-heated appliances, has a pin-shaped inner member 10 surrounded by a sleeve-shaped outer member 11 with an insulating space 12 between the two members which are joined at their outer ends 110, 111 to form a hot junction, the outer ends 110, 111 of the two members 10, 11 being flattened at the hot junction so that they have a rectangular cross-section with an aspect ratio b: d exceeding 3:1. The axial dimension a of the hot junction is not greater than half the width b. The inner member 10 is shaped before assembly and is pushed into the unformed sleeve-shaped outer member 11 of which the outer end is then deformed under pressure to its final form 111, allowing the inner member 10 to be pushed home, whereupon the hot junction is formed by resistance welding and its end face is ground smooth.

Abstract: 222,540. Cottier, R. G. June 1, 1923. Brick-laying machines.- A machine for laying bricks comprises a travelling band 1. Fig. 1, for conveying the bricks 2 by gravity, a guide-plate or shoot 3, movable deflecting plates 5, Fig. 3, acting in conjunction with a device 7 for turning the bricks as headers when required, pusher rods 8. and a mortar hopper 9 An auxiliary conveyer 36 has projections which space the bricks before they reach the shoot, and a gate 26 or trip-piece times the passage of the bricks from the shoot. The turning device 7 is a bottomless box and can be lifted bv a cam independently of its rotation by a cam-actuated crank 22. To lay headers, the device 7 is lowered with the deflecting plates 5, and the bricks pass to a flat plate and a spring check 6 under the device 7. The pusher rods 8 are reciprocated by an oscillating wheel 19, pinion 14, and rack 13, and carry pivoted pieces 15 which draw the bricks into the receptacle 16. The cover of this receptacle is moved diagonally above the bottom of the hopper 9 to release the mortar for the bed and again for the joints; one side of the receptacle is moved inwards to adjust the bricks, and they are pressed downwards by cams acting on a plate 41. The machine is suspended from rails 31, and the conveyers are fed by hand from a cradle 50.

Patent GB-402085-A (GB)
Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1932-05-23
Abstract: 402,085. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, BEALE, C. E., 59, Towers Road, Wavertree, and RICHARDS, I. T., 61, Muirhead Avenue, all in Liverpool. May 23, 1932, No. 14592. [Class 40 (iv).] In a telephone system provided with switches which hunt for and are held by a potential on the test wire and in which metering is effected by reversal of this potential, a relay is provided to respond to this reversal and transmit back a metering impulse, the holding relay being held energised over a second winding whilst the reversed potential is being received over the test wiper. A rectifier in the test circuit discriminates between the marking or holding and the metering potentials, and the relay which repeats back the metering impulse also acts as both the change-over relay and the interruption relay. When the switch is seized, A operates followed by B and the first impulse series is repeated by A to VM, G, which holds in series with VM during the train, shorting its left hand winding to make it slow to release. When the train terminates, G falls away completing the circuit for RM and G and RM interact to step the wipers until either P1 or P2 finds a free line, when HA or HB operates to switch the circuit through. If P1 and P2 both encounter free lines priority is given to P1. The metal rectifiers MRA, MRB test the direction of current flow over the test wipers to prevent the switch cutting in on a reversed polarity test. Assuming P1 has found a free line, HA operates over its two windings in series and shorts out its left hand high resistance winding to mark the line as busy. A, B and G fall away. If no free line is encountered the switch steps to its eleventh position, cam springs S operate, HA is energised over YA to hold A, and busy tone is returned in the usual way. When the switch train has been completely set and the called subscriber has replied, the potential received back over P1 is reversed in sign, enabling G to re-operate in series with the left hand winding of HA. G repeats back a booster battery metering impulse over P to meter the call. No change occurs in the polarity of the magnetic flux in HA as, although the potential on P1 is reversed in sign, the connections to the left hand winding of HA are transposed. When the metering pulse terminates G relapses and HA is again held over its low resistance winding. A traffic recorder may be connected over 10 if required. Specifications 368,821 and 401,695 are referred to. The Provisional Specification states that the devices MRA, MRB may be metal rectifiers, gas discharge tubes or vacuum tubes.

Arms 21<SP>1</SP> arranged to rotate with a shaft 16 are positioned adjacent the ends of the belt 1 to pass between a pair of said belts to lift and transport a bottle b along a pair of curved supports 20. The supports deliver the bottles in a substantially horizontal disposition on to a pair of spaced endless chains 37, which in turn deliver the bottles to containers 40 attached to an intermittently driven endless chain 41. Desposed above each pair of chains 37 is an arm 48 pivotally mounted on a framework 46 about an axis extending parallel to the chains and angled downwardly at 45 degrees such that with the passage of a bottle, neck first, along the chains 37 the arms are pivoted clear of the path of the bottle by engagement with the taper of the neck. If, however, the bottle is in the reverse position, i.e. bottom first then on engagement with an arm 48 the framewotk 46 pivots with its mounting shaft 44, to which is attached an arm 50 for engagement with a micro-switch 52. The switch may actuate a visual or audio warning or may disengage a clutch (see Division F2) to disconnect the drive to the shaft 16. The arms 21<SP>1</SP> are connected to the shaft 16 by a torque limiting means comprising balls 27 urged by springs 28 into engagement with indents 30 in the shaft 16.

Patent GB-617350-A (GB)
Title: A process of and apparatus for separation of one or more metals from alloys
IPC: C22B7/00
Filed: 1946-05-17
Abstract: A process for separating metal constituents from alloys consists in melting the alloy, causing stirring action in the molten alloy during the separation treatment by induction current and treating the alloy while so stirred with air, steam or gas, either alone or in conjunction with salt mixtures capable of absorbing one or a group of metals contained in the alloy or by treating the stirred alloy with salt mixtures alone.  Different salt mixtures may be used successively, each mixture being capable of absorbing different metals from the alloy and each salt mixture being removed before the succeeding one is added.  The alloy may be melted by electrical resistance heating or melting and stirring may both be effected by high or low frequency-induction in an induction furnace.  The apparatus used may consist of an induction furnace and a set of gas blowing tuyeres fitted on top of the furnace and adapted to blow into the centre of the bath of metal in the furnace, the tuyeres being adjustable so that the discharge end thereof can be raised or lowered to blow either on the surface or within the molten metal, a hood completely covering the top of the furnace and through which the blowing gear passes, and a discharge pipe connected to the hood to allow the passage of gas with entrained metal oxides.  The Specification refers to the removal of zinc from brass contaminated with more than 0.01 per cent antimony or with iron or aluminium, magnesium cadmium and sulphur in which process air or gas is blown over the surface of the molten brass, the zinc being liberated and blown away as metal or as zinc oxide.  Tin and antimony may be separated by the process of the invention from an alloy of these two constituents and lead by covering the molten alloy with a mixture of soda ash, borax and fluorspar in the ratio of 2 : 1 : 1, blowing with air or oxygen-enriched air to remove the tin, removing the salt layer containing the tin and then oxidizing and absorbing the antimony in a fresh salt layer of the same composition during continued blowing.

This is said to reduce mixing of the phosphors during manufacture with resulting improvement in colour purity. Barrier electrodes S n  can confront the ribs g n . In Figs. 4 and 5 the red phosphor is in the same position but the green and blue phosphors are in different sides of the ribs. The invention can be applied to a D.C. panel as shown or an A.C. panel where the electrodes are covered by a layer of dielectric, Fig. 7 (not shown). The panel is filled with rare gas at low pressure.
