A radiation detector includes a thermal sink 22, Fig. 3, with a film of thermally conductive but electrically insulating material 24 spanning a cavity 23 in the sink with a collector body 26 of electrically conductive material-which in use will be heated by the detected radiationon the film overlying the cavity, this body also serving as the junction bridge of a thermocouple consisting of thermoelectric members 28, 30, each of which is physically connected at one end to the body 26 and thermally coupled (through the film 24) to the sink at the other end. The junction may be covered by a radiation absorbing body 40. A single body 22 may carry a plurality of couples spanning a single cavity and the couples may be connected in series by linking member 28 of one couple to member 30 of the next by cold junctions 29 as shown in Fig. 2. At their cold ends the members 28, 30 may be covered by highly thermally conductive bodies 50 (Figs. 2A and 3A, not shown) to improve the thermal coupling to the sink. Preferred materials are: for the sink 22, copper or aluminium; for the film 24, aluminium oxide; for the radiation collector 26, gold or silver; for the thermoelectric members 28 and 30, antimony and bismuth; for the radiation absorbent body 40, a porous agglomeration of surface oxidized particles of bismuth; and for the thermal coupling members (50) at the cold junctions, gold or silver. The collector body 26 and thermoelectric members 28, 30 may be deposited by evaporation through photo-resist masks, and the oxidized bismuth coating 40 by vapour phase deposition of bismuth smoke derived by heating a bismuth source in a low pressure oxidizing atmosphere.

In a multi-valve oscillator system, each valve is associated with a number of resonant circuits and a coupling of an odd number of half-wavelengths is arranged between circuits of different values to stabilize the frequency and phase of the generated oscillations. Two magnetrons 13, 14, Fig. 5, may be coupled over a coaxial path 20 of adjustable length. If the cavities 16, 22 are to be in-phase then the path is an even number of wavelengths, but if there is a phase reversal in the coupling, the path is made an odd number of wavelengths. Similar couplings 26, 27 are provided for connection to further magnetrons while output is taken from the guides 32, 34. A number of magnetrons may be arranged in a ring, Fig. 4 (not shown), with different lengths of coupling to reduce the possibility of the system operating at an undesired frequency. Coupling between non-adjacent magnetrons may be employed and a number of couplings may be joined at a common point, Fig. 6 (not shown).

The substrate or coating may comprise particles of natural stones, slags, shales, silaceous pit residues, devitrified soda glass, crushed refractory brick, ceramics, spinels, alumina, chrome residue, chrome ore, iron ore or oalcined bauxite. The natural stones may be of igneous or metamorphic rock such as metamorphic grit stone, basalt or granite. The coating particles may, in addition, comprise bauxite or a spinel/alumina mixture. Where necessary the coating particles may be mixed with a binder having a lower melting point than the coating particles. The binder may be a slag, "red mud" from aluminium manufacture, clay, pulverised fuel ash, shale, sodium fluorosilicate, sodium silicate, olivine or other silaceous or calcareous mineral, optionally mixed with a flux such as calcium fluoride. Where a binder is not used the particles and granules are heated in a rotary kiln so the surface of the granules melts and accepts the particles. When a binder is used, a stiff slurry of binder and particles is mixed with granules in a rotary kiln which is slowly heated to first dry then sinter the coating at 800 to 1600C. Alternatively a mixture of damp granules, particles and binder may be used. Furthermore the binder and particles may be formed into pellets of a size not greater than the granules: then the pellets may be mixed with granules in a rotary kiln. The pellets may be dried or fired before being so mixed.

Title: Improvements in or relating to arc-welding
IPC: F27D99/00
Filed: 1953-07-03
Abstract: 721,017. Supply systems for welding arcs. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 3, 1953 [July 8, 1952], No. 18501/53. Class 38 (4). In an arrangement for reducing the voltage in an arc-welding circuit during periods of non-welding, of the kind wherein a relay 9 for switching in or out a voltage-reducing resistor is controlled by contacts 13, 14 of a further relay 15 responsive to the voltage obtaining in the welding circuit 6, 10, reduction of the circuit voltage during short unintended interruptions of the arc is avoided by associating with the winding 18 of the relay 15, a timing circuit 17, 19 which delays, by say one second, the response of that relay to the high voltage then obtaining in the welding circuit. The relay 15, which may be energized over a rectifier 16, must be such that it will pick up (with delay) when fed, over the timing resistor 17, by the high open circuit voltage, will drop out quickly (with resistor 17 short-circuited by contacts 24, 25) under the voltage conditions obtaining whilst striking the arc and will not pick-up at the normal welding voltage. Contacts 20-22 of relay 15 ensure that the timing condenser 19 is discharged (by resistor 23) and isolated from the relay winding 18 and thus ineffective to impose delay during " drop out " of the relay. The voltage-limiting resistor controlled by the relay 9 may be one element of a potentiometer 5 which shunts the secondary winding 4 of the welding transformer 2.
