Abstract: 611,260. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. April 25, 1946, No. 12525. Convention date, May 2, 1945. [Class 39 (i)] A tuning mechanism for adjusting the spacing between two electrodes resiliently connected together in an electron discharge device of the velocity modulation type, comprises a lever system interposed between the electrodes adjustable by a single controller device to produce a purely translatory motion between the electrodes that has to rotational component. A cavity resonator 16, Fig. 2, of the type described in Specification 554,574, comprises two portions interconnected by a flexible diaphragm 26. The resonator portions support grid electrodes 17, 18 which are held rigidly with respect to annular metal plates 15, 14 respectively. The metal plates 14, 15 are also interconnected by tension springs 29, Fig. 3. Compression springs may be used, Figs. 6-8 (not shown). The parallel motion producing mechanism is chiefly supported on the lower plate 14 by means of a mounting plate 30. The mechanism comprises pivoted at 33 a tuning lever 35 which has a bifurcated lower leg 34 provided at both terminals with upstanding tabs 37, 38, Fig. 5. These tabs have bearings 39, 41 seating on the adjacent ends of a U-shaped yoke lever 42 rockably supported by pivots 43, 44. One of these bearings may be the end of a screw which may be adjusted in the leg 34, to ensure proper bearing contact and relative parallelism between the leg 34 and yoke 42, Figs. 6-8 (not shown). Struts 49, 50, 51 threaded in plate 15 bear on the rockable levers, Fig. 3. Rotation of the tuning lever 35 about pivot 33 to oppositely rock the leg 34 and yoke 42 and so produce parallel motion between plates 14, 15 and hence electrodes 17, 18, is -effected by a micrometer mechanism comprising drum 61 controlling tuner shaft 58 for course adjustment and knob 71 controlling trimmer shaft 57 for fine adjustment. The fine adjustment shaft may be dispensed with, Figs. 6-8 (not shown). The struts 49, 50, 51 may be of a compound thermal compensation type and are pre-adjusted to secure the original parallelism between the electrodes. In another embodiment, Fig. 9, tuning lever 113 is engaged by a tuning shaft 119 for course adjustment, and the leg 112 of the tuning lever 113 supports on pivot 122 a trimmer lever 124. Adjustment of trimmer lever 124 by trimmer shaft 125 results in a small but permissible departure from parallelism of the resonator grids for fine tuning.

Title: Improvements relating to means for and methods of performing dimpling, countersinking or analogous operations on sheet metal
Inventor: SINCLAIR JAMES
IPC: B21D22/04
Filed: 1956-04-25
Abstract: 804,122. Dimpling; flanging; joggling. SHORT BROS. & HARLAND, Ltd. June 3, 1957 [April 25, 1956; May 20, 1957], Nos. 12702/56 and 15923/57. Class 83 (4). A process of performing a dimpling or countersinking, flanging or joggling operation on a sheet metal workpiece, e.g. alloys of aluminium with magnesium or titanium, is characterized in that it is effected in stages during which (a) the workpiece is submitted to an initial pressure between dies maintained at the appropriate temperature until the workpiece has absorbed sufficient heat to enable it to collapse under said initial pressure, and (b) when full forming pressure is exerted to complete the formation of the dimple or countersink. Apparatus for carrying out the process comprises a C-shaped yoke 10 carrying a stationary die 13 and a reciprocable die 14 operated by an hydraulic ram 21 through links 16, 17 and 19. Each die heater comprises a core plate 23 (Fig. 9) bonded to the die and wrapped in a mica insulating sheet 24 about which is wound an electrical resistance element 25 the whole being enclosed in an insulating envelope 27. Temperatures between 100‹ and 500‹ C. may be obtained with a voltage of 24 volts and a current of 4 to 5 amperes. The die 13 is provided with a pilot pin 28 which locates the workpiece in the die prior to the dimpling or countersinking operation and when the dies reach the correct temperature thermocouples (not shown) in the dies actuate a control valve to admit low-pressure fluid to the ram to lower the heated die 14 into contact with the workpiece. Heat absorbed by the sheet from the dies is automatically compensated by a boost circuit on the control apparatus. When the resistance of the workpiece is overcome the die continues its movement and an adjustable striker 30 engages a bell crank lever 31 to trigger a micro switch 32 which actuates the control valve to admit full working pressure to the ram and die 14. As soon as full working pressure has been applied, automatic means are energized to retract the ram and open the dies to reset the apparatus for the next operation.

Abstract: 311,218. United Water Softeners, Ltd., and Higgins, E. B. Feb. 6, 1928. Divided on 311,253, Chloramines, caustic soda, and chlorine; obtaining; liquids, treating; electrolytes, circulating; electrodes.-A plant for the manufacture of sterilizing and germicidal agents and the like comprises two or more electrodes arranged so that the space between them is extremely small relatively to the cross-section of either electrode; the electrolyte enters through one or both of the electrodes. In the apparatus shown, electrolyte is forced through central apertures in both electrodes n, Fig. 3; the streams impinge to form a discshaped radial stream o, which flows through a gap between insulating sleeves r. The products of electrolysis formed at either electrode are forced by the pressure of the liquid through fine passages s into annular ducts t from whence they are conducted away by valve-controlled pipes u. The electrodes may be adjustable to vary the gap which should be about 0.2 m.m. In a modification, the passages s are dispensed with, the products of electrolysis passing off with the excess electrolyte. In another modification, a number of intermediate bipolar electrodes are bolted with spacing members between end electrodes so as to form a number of radially outward streams of electrolyte. In another modification, electrolyte enters through the anode only and impinges on the cathode so as to carry away the products of electrolysis. Brine may be electrolyzed for the production of caustic soda and chlorine. Fig. 1 shows a plant for the sterilization of a main water supply by the introduction of chloramines. Water from a pipe e is bye-passed through a vessel a filled with common salt and a vessel b containing chloride or other salt of ammonium to an electrolytic cell l of the kind described from which it is returned to the pipe e by a pipe p. The proportion of water passed through the cell is controlled by valves m. The electrolyzing current may be generated by a dynamo h coupled to a watermotor f driven by the water stream.

Title: A method of and apparatus for manufacturing helically-twisted concrete reinforcing rods
IPC: B21D11/15
Filed: 1957-04-25
Abstract: 803,310. Twisting. KOHLER, F. April 25, 1957 [June 15, 1956], No. 13220/57. Class 83 (4). A method of making rectilinear twisted concrete-reinforcing rods, in which the ends of the rod to be twisted are held in gripping devices that are twisted relatively to each other whereafter the rod is allowed to twist oppositely in the measure of its elastic torsional deformation, is characterized in that the reverse twisting produced by the natural elasticity of the rod is braked or retarded during or after the release of at least one of the gripping devices. The braking may be effected by gradual release of the jaws of one or each gripping head, the jaws being actuated by fluid pressure or by mechanical means. Alternatively a separate braking head may be associated with one, or both, of the gripping heads which is applied to the rod after twisting has been completed and gradually lifted to allow the rod to untwist slowly after the gripping head has been released. The braking head may be locked to the rod and allowed to rotate, under a brake, as the rod untwists. For long and heavy rods these may rest on supports between the two gripping heads, the frictional force between the rod and supports being sufficient to brake the untwisting, the other braking devices may be used as well.

Abstract: 862,094. Laminates. MENDIP (CHEMICAL ENGINEERING) Ltd. July 24, 1959 [April 26, 1958], No. 13315/58. Class 140. [Also in Group XIII]  A heat-exchanger water box or header (see Group XIII) is made by applying successive layers of fibre reinforced synthetic resin to a mould each layer-being separately polymerized or all of the layers being polymerized simultaneously. In forming the box, an initial layer (layer B), of polyamide, polyester or polyacrylic fibre is moulded to the required inside shape of the box, and then a synthetic resin such as a polyester or epoxide is applied in the form of a viscous liquid and worked into the fibre layer, the resin containing a suitable catalyst or hardener such that it will harden only after several days at room temperature, Reinforcement in the form of a prefabricated steel network R is then pressed into the resin before the latter hardens and thereafter a final layer of (layer C) of synthetic resin reinforced by glass, polyamide, polyester, polyacrylic or other fibres is applied. Layers B and C may contain a filler such as calcium carbonate to modify the characteristics of the material, layer C containing more filler than layer B, this being said to obviate excessive stresses which would otherwise arise due to unequal contraction of layers B and C. A condensed silica may be added to the resin to facilitate application. Each of the layers B and C may be formed by several applications of the resin. The steel network R may be omitted.
