Abstract: 272,146. Chaplin, C. J. March 23, 1927. Linear-dimension gauges.-A measuring in. strument, specially adapted for measuring the summer growth of wood with reference to the total width of wood made, comprises two scales E, D, and a single cursor H so arranged that as the cursor is moved over a series of distances, a pointer G shows on the scale D the total distance traversed, and a pointer F shows on the scale E the sum of selected distances within the series. The scale D is attached to a plate A which is slidably mounted on a pillar N of a base plate M, and is slotted to receive a slide B upon which the scale E is marked. The slide B is slotted to receive a slide C which carries the pointers F, G and the cursor H. A magnifying eye-piece P is arranged over the cursor H, which may be of any suitable form. In use, the piece of wood to be measured is placed upon the base M, and the plate A is lowered until a pin K engages the wood. An adjustable pin L is engaged with the wood to hold it rigid. The cursor is then traversed across the zones corresponding to alternate summer and winter growth in sucession, the distance corresponding to winter growth being traversed by operating a micrometer nut S which moves the slide B, and the distance corresponding to summer growth being traversed by operating a nut T which moves the slide C. The scale E may be calibrated in percentages of a total movement shown by the scale D. The apparatus may be used in connection with textiles, and several secondary slides C may be provided. The arrangement of the scales &c. may be modified.

Title: Improvements in and relating to the coking of liquefiable bituminous substances
IPC: C10B55/00
Filed: 1951-04-10
Abstract: 692,325. Coking pitch etc.; vertical retorts. RUTGERSWERKE AKT.-GES. April 10, 1951 [May 8, 1950], No. 8269/51. Classes 51(ii), 55(i) and 55(ii) A two-stage continuous process for the coking of pitch and the like comprises first heating the pitch to render it viscous and to free it from most of its volatile matter and then coking the viscous material at a raised temperature, the material passing through both stages under the action of gravity. The apparatus consists of a vertical retort 2 surmounted by a distillation column 1. Preheated, molten pitch enters column 1 through a pipe 3 and flows downwardly over plates 4, the column being heated to 300‹- 500‹C by a jacket 5 supplied with hot combustion gases. The vapours from the pitch discharge through a pipe 11 whilst the viscous residue containing about 20 per cent volatile matter passes in the form of thin streams through a distributer 13 and falls through an empty coking chamber 14 which forms the top section of the retort 2, and which is heated to 1000‹C by a jacket 18 supplied with hot combustion gases. The pitch is coked as it passes through chamber 14 and collects in a calcining chamber 15 into which air is admitted through pipes 24, part of the coke being burnt to free the remainder from residual volatile mattter and to supply the hot combustion gases for the jackets 18 and 5. Additional heating gas and air may be supplied through pipe 19 and to ensure even heating, the gases enter and leave the jackets through annular channels 20, 22, 7 and 9 which are each provided with throttling strip, as shown at 29 in Fig. 2, the height of which decreases as the distance from the inlet or outlet pipe increases. The calcined coke finally passes into a water jacketed cooling chamber 16 and is continuously extracted from the retort by a worm 17.

Inventor: OATLEY ARTHUR FREDERICK
IPC: F24C7/08
Filed: 1962-03-02
Abstract: 1,040,881. Stoves. OATLEY TECHNICAL DEVELOPMENTS Ltd. March 4, 1963 [March 2, 1962], No. 8295/62. Heading F4W. An electric cooker comprises an oven 4 having in the upper surface of its top wall a heating plate 7 and, above the oven a grill 5 having a horizontal, downwardly directed, radiant 6 confronting heating plate 7 and vertically movable to adjust the distance of the radiant from the heating plate. Radiant 6 and cover 19 are secured to horizontal arms 22 fastened to rails 23 which slide in channels 24, Figs. 3, 4 (not shown), between the rear wall of the oven and its back inner wall 10. Radiant 6 may be raised or lowered by means of a pulley, wire cable and counterweight system, Fig. 2 (not shown). Radiant 6 and heating plate 7 cannot be energized simultaneously since both are controlled by the same switch 21 through a selector switch 34. Radiant 6 or heating plate 7 can only be switched on when the radiant is a predetermined distance from the heating plate. This is achieved either by a detent 36, Fig. 3 (not shown), connected to switch 21 and interlocked with the lower end of one rail 23 or by an isolator switch operated by bifurcated arm 40, Fig. 4 (not shown), engaging a pin on one rail 23 so that raising or lowering rail 23 operates the isolator.

Title: Solar thermoelectric generators
IPC: H01L35/00
Filed: 1960-03-09
Abstract: 887,202. Semi-conductor devices. AMERICAN MACHINE & FOUNDRY CO. March 9, 1960 [March 9, 1959], No. 8307/60. Class 37. A solar thermo-electric generator has a number of thermocouples mounted in a housing with a window through which radiation enters, a cooled junction being adjacent the window and the hot junction, a flat plate receiver being spaced from the window. As shown, Fig. 1, solar radiation enters the housing through the window 6 which has a high transmission in the visible and near infra-red spectrum and a low transmission of longer wavelength and is received on a plate 5 which may be of metal to increase heat absorption. This plate is a poor reflector for wavelengths below α microns and a good reflector and poor emitter for wavelengths above. The window is spaced from the plate by rigid sides of poorly heat-conducting material, for example wood. The sides are sealed with respect to the receiver and window by gaskets, low-melting-point solder, or an organic polymer cement and the window may be doubleglazed with a space between the plates evacuated or filled with an inert gas. Each thermal element is a cylindrical ingot of bismuth-tellurium alloy and the element 13 is a metal strip such as copper or aluminium. The couples are connected in series by soldered contacts, but pressure contacts may be used. The hot junctions are in contact with the receiver plate but are spaced from it if it is electrically conducting by flakes of mica or polytetrafluorethylene. Fig. 4 shows an arrangement in which the thermal elements 19, 20 are of a bismuth tellurium alloy with traces of other elements to render them electrically positive or negative joined by copper strips 21, 22. In the arrangement of Fig. 5 (not shown), the whole housing is heat-insulated except the window and a heat sink is provided below the receiver plate. This sink may consist of a reservoir of water, a saline solution or a gravel bed. The space beneath the cover may be evacuated in which case the thermocouples may act as supports, this being a convenient way of making pressure contacts. Further thermoelectric materials referred to as suitable are the heavy metal oxides and sulphides, for example ZnO, PbS and zinc-antimony and bismuth-antimony alloys.

Abstract: 610,711. Aerials ; radiolocation. SPERRY GYROSCOPE CO., Inc. Feb. 3, 1943, No. 8373/45. Convention date, Aug. 12, 1941. Divided out of 610,704. [Class 40 (vii)] In a radiolocation scanning system in which a reflector is oscillated about one or more axes, the oscillations take place at the natural resonant frequency of the moving system. In the construction shown, Figs. 1, 2, reflector 8 with an antenna element 7 at its focus is mounted for movement about horizontal and vertical axes in trunnions 45 on a yoke 46 pivoted at 47. Yoke 46 carries a transverse bar 48 connected by a spring 49 to a crank disc 51 driven by a motor 52. The rear portion of bar 48 is adjustably connected to springs 53, 53<1>, the system 8, 46, 48, 49, 53, 53<1> being resonant at the desired frequency of oscillation. Movement about a horizontal axis is effected by levers 64 connected to the plungers of two solenoids 62, 62<1> energized by the closure of contacts 61 by projections on crank disc 51 so that the rate of vertical scanning bears a definite ratio to that of horizontal scanning. Springs 131, 132 connected to levers 64 control the resonant frequency for the vertical oscillations. In a modification, Fig. 5 (not shown), the antenna element 7 is oscillated in a vertical plane for the horizontal scanning and the reflector oscillates about a horizontal axis for the vertical scanning. Specification 610,704 is referred to.

Title: Improvements in or relating to phial making machines
IPC: C03B23/18
Filed: 1951-04-11
Abstract: 699,035. Making phials. GUSTI, A. April 11, 1951 [April 11, 1950], No. 8375/51. Class 56. An apparatus for automatically opening and annealing phials and selecting and sorting the phials according to the diameter of their necks comprises a notched framework'6 adapted to receive the phials, means 3, 4 to advance the phials by transferring them from notch to notch along the framework, annealing means 25, 26: and opening means 36 adjacent the beginning of the framework, and a series of gauges 5 forming part of the framework so that each phial is introduced to each gauge in succession and may pass. through one gauge under the action of gravity and so be removed from the framework. The phial from the blowing &c. machine is introduced into a hopper 1 which has an adjustable end wall 2 whereby the position of the phial relative to the framework 6 is adjusted. The phials are collected and moved by a framework consisting of notched inverted U joists 3, 4 adjustably connected by bolts and given a cycloidal translatory movement by means of eccentrics 9, 10 driven by a motor 13 via a friction wheel 7, disc 15, pulleys 16, 18, and belt 17. This movement of the framework 3, 4 is intermittent being arrested when a rod 23 urged by spring 24 engages a recess in the eccentric 10, but freed when the rod 23 is withdrawn by means of a cable 22 which is operated by passage of a pair of pliers of the blowing &c. machine. While the phial is supported on the first notch of the framework 6 and on gauge 38 the bottom of the phial is heated by a burner 25 which directs a series of small parallel circularly arranged flames, while the tip is heated by an opening burner 36 whereupon the heated enclosed air forces a hole in the tip of the phial. At the second notch the phial is heated for rapid annealing by burner 26 which has convergent flame jets to heat the body in the proximity of the base without raising the temperature of the base. Gauge 38 selects and removes any phials with irregular necks. At successive notches the top of the phial is supported on gauges 5, which vary for example by 0.25 mm., until it passes through a gauge and slides tip forward into the, corresponding slide 27-30 and hence to the collecting box 32-35. Any phials which will not pass through a gauge 5 are passed to a collecting box 31. The lever 32a of an automatic counter is fitted in the hopper 1. A jet of air introduced through a nozzle 37 arranged in the slide of the hopper 1 gives an audible signal at the passage of a phial, and this signal varies, to warn the operator, when an unsound phial passes.
