Title: Improvements in and relating to the bonding of dissimilar metals to one another
Inventor: WALTER DEREK OSCAR
IPC: B23K35/30
Filed: 1964-08-13
Abstract: 1,088,052. Welding by pressure. JOHNSON MATTHEY & CO. Ltd. Aug. 10, 1965 [Aug. 13, 1964], No. 33014/64. Heading B3R. In a method of bonding together two dissimilar metal parts capable, on heating together, of forming an eutectic alloy, the metal parts are fed along a guide and during the feeding at least the mutually contacting faces of the two metal parts are heated to a temperature above the eutectic melting temperature for a period sufficient to allow the formation of enough liquid eutectic alloy necessary to effect an efficient metallurgical bond at the said faces without significant deformation. Slugs of metal parts 14, 15, for example copper and silver slugs for bonding to form electrical contacts, are fed through a tube 1, which may be a thickwalled silica tube, to be initially heated by a resistance heating wire or tape 6 and subsequently heated to above the eutectic melting temperature by a similar heater 9. The slugs are then cooled by a fluid cooler 7. Hydrogen may be introduced into the tube at 10. By means of, for example, a thyristor device or saturable reactor, and a thermocouple a variable power supply is delivered to the heaters to take account of the speed of the slugs through the tube in order to produce consistent uniform bonds. The distance between the heaters 6 and 9 may be adjustable.

Title: Edge-lighted photo timer
Inventor: BALL JACK
IPC: H05G1/44
Filed: 1958-10-24
Abstract: 856,520. Timing X-ray exposures. PICKER X-RAY CORPORATION WAITE MANUFACTURING DIVISION Inc. Oct. 24, 1958, No. 34059/58. Class 40(3). In apparatus for timing X-ray exposures of the type in which light from a flourescent material in the path of the X-rays is directed by material of high refractive index to a photo-tube, a number of pieces of the fluorescent material of size appropriate to the part of the body under examination is provided, each associated with a photo-tube which may control the timer. In the arrangement shown in Fig. 3 the X-rays after passing through the subject under examination and the X-ray film in its cassette fall upon fluorescent material 24 attached to a Lucite sheet which guides the light to a photo multiplier tube 22 and upon a further layer of fluorescent material on the underside of a further light guide 21 associated with another multiplier tube (not shown). A paper screen 26 renders the central portion of the lower square 25 ineffective to avoid the variable filtering effect of the upper square. A double sided aluminium reflector may be provided between the plates. In a further arrangement (Fig. 4, not shown) fluorescent material is provided on both faces of the light guiding plate. In a further arrangement Figs. 6-8 (not shown) the light guides and fluorescent material are situated between the X-ray source and the film cassette. The Lucite sandwich consists of upper and lower lucite plates 44, 45 carrying respectively patterns 47, 48 of fluorescent material. The upper fluorescent material 47 is carried on a strip 44a dovetailed into the upper plate 44, the cracks in the dovetail being filled with an aluminium powder. The effect of the strip is to minimize light dispersion from the small fluorescing area. In a vertical arrangement (Fig. 10) the three plates of Lucite 60, 61, 62 are mounted side by side each carrying fluorescent material 60b, 61b, 62b. The outer plates are so spaced as to correspond with right and left chest cavities and direct their light to a single photo-multiplier 63 although they may feed separate multipliers 63, 66. The central plate feeds multiplier 64. The circuit consists of a condenser charging at a rate determined by the selected multiplier tube to trigger a relay-operating tube. A switch device permits connection of the selected tube in circuit.

Patent GB-487321-A (GB)
Title: Improvements in or relating to thermionic valve circuits
IPC: H03K4/12
Filed: 1936-12-12
Abstract: 487,321. Valve generating circuits. WHITE, E. L. C. Dec. 12, 1936, No. 34161. [Class 40 (v)] A relaxation oscillator comprises a condenser 8 adapted to be charged, or discharged, at a desired rate whilst an associated valve 1 is nonconducting, the condenser charge restoring instantaneously to its normal value through the grid-cathode space of the valve 1 when flow through a further valve 2 ceases, the two valves being inter-connected by a common impedance 6 in their cathode leads. As shown in Fig. 1, the condenser 8 charges over resistance 9. The valve 2 is conducting so that the cathode 11 of valve 1 is at potential V2, Fig. 4, due to the anode current of valve 2 flowing through resistance 6. As the condenser charges the effective bias of grid 10 becomes less negative so that valve 1 begins to pass anode current. This results in a fall in the potential of anode 12 and this is applied to grid 13 so that the anode current of valve 2 is reduced. This decreases the potential of cathode 11 so that the anode current of valve 1 increases further, the action being cumulative until valve 2 is biassed to cut-off. The potential of cathode 11 falls rapidly as indicated by 26 /24, Fig. 4, and the potential G of the grid 10 follows the cathode potential down to value V1, the condenser 8 discharging over the gridcathode space. The condenser 5 charges through resistance 7 and the anode-cathode space of valve 1, the potential of grid 13 starts rising again, valve 2 begins to conduct, valve 1 is cut off and the cycle repeats. The condenser 8 may be connected in parallel with resistance 9, in which case it charges rapidly and discharges at a desired rate. An alternative arrangement using a pentode is described in which resistance 3 and condenser 5 are connected to the screen grid and the output is taken from the anode. The invention may be used for frequency division or multiplication and for counting impulses, controlling pulses of either positive or negative sense being applied to a suitable point in the circuit.
