Patent GB-268812-A (GB)
Abstract: 268,812. Jerike, J. April 3, 1926, [Convention date]. Thermometers.-Apparatus depending on the differential expansion of metals for use as a thermometer or for thermostatic control comprises an expansion member consisting of one or more elements each comprising two similar parallel members 1, 4 connected by diagonal members 2, 3 having a coefficient of expansion differing from that of the members 1 4, the diagonals being connected to the members 1, 4 by hinges or the equivalent g1 of such form that changes in the distance between the members 1, 4 are produced as a result of temperature change by stresses acting along the diagonals, without any bending of the members taking place. In Fig. 1 the diagonals are not connected to each other in any way at the point at which they cross; in Fig. 2 they are connected by a single joint g2 at their point of intersection, in which case the arm 2 may be integral with the arm 3 and the arm 2<1> with the arm 3<1>; in Fig. 3 the diagonals are connected by a member d and two joints g2. In using the temperature-sensitive element the member 1 is fixed and the movements of the member 4 towards or away from the member 1 are utilized for measuring or controlling temperature. Fig. 9 illustrates a number of elements connected together in series to produce a magnified movement. When a number of elements are used as in Fig. 9 the diagonal members may consist of unitary steel bands q, q<1>, Fig. 12, passing through the system and soldered to the parallel members or to caps fitting over the said members. The base b, Fig. 9 may be adapted to be adjusted in position by means of a screw and the lengths of the parallel members may be adjustable as by a right-and-left handed screw arrangement inserted in their length. In order to ensure the parallelism of the members 1, 4, distance pieces r, Fig. 23, may be employed having claws r1 and tongues r fitting between the parallel members. The joints between the parallel and diagonal members may be made with play or lost motion so that no operative movement of the system occurs until the temperature reaches a predetermined minimum. This lost motion may be made capable of adjustment so that the apparatus can be adapted to operate at a number of different temperatures. Instead of linear members above described the members 1, 4 may be made in the form of parallel circular rings connected by spherically-curved plates constituting the " diagonals."

Abstract: 750,021. Magnetron oscillators. WESTERN ELECTRIC CO., Inc. Oct. 2, 1953 [Oct. 2, 1952], No. 27071/53. Class 39 (1). [Also in Group XL (b)] Hollow dielectric waveguides 30, 40 are used, separately or together, to discriminate between the oppositely-travelling components of a degenerate mode, waveguide 30 being arranged to absorb the unwanted component more heavily than the wanted component, while waveguide 40 is directional so that the unwanted mode passes to non-reflective termination 45 and the wanted mode passes out to load 38. The arrangement shown is for the #/2 mode and every fourth one of segments 14 is connected by one of the set of four straps 26 ... 29. Resonator 30 is coupled to three successive inter-segment cavities by couplings 32, 33, 34, the centre coupling being double that of the outer ones and reversed in direction. Vanes 35 reduce the wave velocity in the guide so that the couplings are a quarter wave apart and it is stated that this causes the anticlockwise mode to be strongly absorbed by non-reflective inclined lossy wedges 131, while the clock-wise mode is not so strongly absorbed. Resonator 40 is similarly loaded by vanes 55 and is coupled over five cavities with similar couplings 51 ... 54 to the first, second, fourth and fifth and none to the third; this is shown to give co-directionality with the desired suppression of the anti-clockwise mode and transmission of the desired clockwise mode by way of a transition section and window to load 38. Similar arrangements can be made for the 3#/2 mode, Fig. 3 (not shown).

Abstract: 735,040. Making cupped forms. BIGINELLI, O. F. A. Nov. 19, 1951 [April 17, 1951; Sept. 18, 1951], No. 27125/51. Classes 83 (2) and 83 (4). Extruding; cupping.-A cylinder with a closed end is made by extruding a solid billet into an annular space between a die and a mandrel and then drawing down the walls of the cupped blank by pushing it through the die on the end of the mandrel, a restriction at the outlet of the die during the extrusion stage causing the metal to conform closely to the shape of the mandrel. A cylinder 2 is secured to the frame 1 of the machine by a flange 5, pins 8 and nuts 9. A cap 14 is screwed over the upper end of the cylinder and through it passes a fluid pressure inlet pipe 13 which screws into a closure member 10 with a sealing ring 11. A piston 500 with a sealing ring 52 operates in the cylinder and carries a mandrel 49 which passes through a sealing ring in the lower end of the cylinder. Screwed into the flange 5 is the upper end of a generally tubular cage 17 to the lower end of which a die 37 is secured by a collar 41. The die, Fig. 5, has a generally cylindrical bore with a flared lower end 41 and a slightly restricted throat portion 46. The lower end of the mandrel is slightly tapered. An electric heater 48 surrounds the die. In operation, a solid billet is placed on the upper surface of a fluid pressure ram 55 which is raised so that the billet is extruded through the annular opening formed between the mandrel and the die, the throat 46 of the die, Fig. 12, causing the extruded metal to conform to the shape of the mandrel. The ram 55 is then lowered and pressure fluid supplied to the inlet 13 so as to force the mandrel down, thus drawing the extruded walls of the blank through the narrowing gap between the throat and the tapered end of the mandrel. A stripper 64 (not shown) is moved into position around the mandrel immediately below the cage 17 and the piston 500 raised by pressure fluid admitted to the cylinder 2 through an inlet 31. Cooling liquid may be circulated around the mandrel in a space 27 formed beneath the cylinder 2 and above a ring 22 seated within the upper part of the cage 17. Nozzles may eject lubricant on to the mandrel.

Abstract: 181,646. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 13, 1921. Stop-gear. - Speed governing and emergency governing is effected by attaching the spring- loaded supply valve 9 of a prime mover to the central portion of a lever 22, one end of which is operated by the speed governor 37, while the other end constitutes a movable abutment which falls to close the valve 9 when the emergency governor operates. A link 24 attaches the lever 22 to the piston 41, which is held against the cover 44 of the cylinder 42 by fluid pressure, preferably of the oil in the lubricating system, supplied from a chamber 64, Fig. 2, through the valve 50 operated by the emergency governor. The emergency device comprises an eccentric ring 62 flexibly mounted on the engine shaft 38, operating at excessive speeds a trip lever 57 which releases the rod 49 and spring 56, and permits the double-ended valve 50, 51 to slide to the right on the rod 49, thus closing the supply valve 50 and opening the valve 51 through which the pressure fluid is discharged from the cylinder 42 by conduit 45. The piston 41 then falls under the action of the spring 43 to close the valve 9. The trip-gear is re-set by moving the lever 67 to the left to engage the rod 49 and reverse the valve 50, 51 by the pressure of the spring 56 engaged by a collar 55 on the rod, the tripping lever 57 automatically re-setting itself to engage the end of the rod 49 by the pressure of the spring 60. A small amount of the pressure fluid is permitted to discharge past the piston 41 by passages 75, 74, and needle valve 73, for cooling purposes. The speed governor preferably operates the end 21 of the lever 22 through the system of levers shown in Fig. 1 in combination with a servo-motor 28, 29, rack and pinion 26, 25, and cam plate 19. The valve is positively closed in the event of sticking, by the pin 40 on the cam plate, engaging the hook 39 on the lever.
