Title: Improvements in electrical delay lines
Inventor: BUHLMANN FREDERICK THEODORE
IPC: H01J23/28
Filed: 1958-02-27
Abstract: 882,997. Travelling wave tubes. MULLARD Ltd. Feb. 27, 1958, No. 6384/58. Class 39(1) [Also in Group XXII] The interdigital delay line of a travelling wave tube is made by taking grid wires 1, Fig. 1, which are flat or substantially flat and which are provided with two longitudinal parallel backbones 2, the wires then being bent to hairpin form round a preferably grooved mandrel 5, Fig. 4, and the backbones 2 clamped between a pair of supports 7 (which may form parts of a waveguide) by releasable securing means such as bolts 8 two sets of such hairpin elements being assembled to form an interdigital line. The backbones which are metal strips 2 are arranged in a circle and adjacent ones are inclined in opposite directions to a radius, the grid wire being wound in grooves in the backbones when a mandrel carrying the backbones in recesses therein is rotated by a shaft. After removal from the mandrel the wires are attached to the backbones. The wires are severed at the mid points between alternate backbones so as to leave wire lengths extending between backbones 2a and the free ends are trimmed off. After removal from the mandrel 3 and clamping to the mandrel 5 the wires are attached to the backbones by brazing the wires to the backbone grooves or by swaging the grooves over the wire and the backbones are brazed to each other. The wires are straightened by moving the backbones in opposite directions until the wires extend at right angles to the backbones. The grids are then stretched to set them. The grid wires are then bent over the curved edge of the mandrel 5 to hairpin shape; the mandrel 5 preferably but not necessarily has grooves at 6 to take the grid wires. The recesses or grooves in 2 are -inclined at 45 degrees as shown in Fig. 4, and bending the wires over the mandrel brings the backbones 2 into contact with one another. The hairpin structure is clamped to mandrel 5 and the assembly is secured between two blocks 7 by bolts or other threaded members 8. The clamp holding the wires 1 to the mandrel 5 is now removed and the mandrel 5 leached out by solvent. The two sets of hairpins each hairpin being carried by an individual pair of backbones 2 are now interleaved and clamped together by bolts to form an interdigital delay line. In a modification the mandrel may be leached out before the structure is bolted together between blocks 7. After bending the wires into loops the backbones are brought into contact with a different surface of the mandrel and the mandrel with the looped wires thereon is put between two metal blocks. The two backbones can if desired be additionally secured together by fusion of metal.

Patent GB-787262-A (GB)
Title: Improvements in or relating to inking devices for printing machines
IPC: B41L13/18
Filed: 1955-03-04
Abstract: 787,262. Inking-apparatus. ROTOWERKE AKT.-GES. March 4, 1955 [March 8. 1954], No. 6502/55. Class 100(2) [Also in Groups XVII and XXIX] Ink is supplied to an inking roller in a printing machine, e.g. a multi-drum stencil duplicator, under pressure derived from the vapour pressure of a volatile liquid propellant which vaporizes at normal room temperature; when ink emerges the vapour pressure reduced by the volumetric increase in the space containing the propellant is restored by further vaporization. The propellant 34 (such as propane or butane) and ink 32 may be contained in a cylindrical container 5, either separated as at 25 or mixed together; where separated as shown a small amount of the volatile liquid may be added to viscous ink to assist flow; when not separated, the proportions may be predetermined to ensure that sufficient vapour is developed to expell all the ink; in the latter arrangement, the outlet is at the bottom of the container. The piston 25 shown is of resilient material and its top fits the container top 22 for maximum ink expulsion. It may be replaced either by a simple rubber bladder (35, Fig. 8, not. shown), clamped at its open end by the edge of the cover 22 (or the base 23), or by a flexible rubber tube (36, Fig. 7, not shown), lying against the container sides, which is clamped at one end by the edge of the cover 22 and is turned back inwardly at its closed end 'to form a space for the propellant 34; as the closed end moves upwards similarly to the piston 25, the flexible wall doubles back further. The container 5 is connected to a flexible pipe 12 by a self-sealing coupling device 27 ... 31 (see Group XXIX), or a simpler coupling (Fig. 4, not shown), which is initially sealed but not self sealing (see Group XVII); the pipe 12 leads to a nozzle 10 mounted in a frame 6 pivoted at 7 and spring-loaded downwards at 8; when the frame 6 is manually rocked, the nozzle valve 11, Fig. 6, is opened by a pivoted cam 20 depressed by a fixed plate 19 extending across the machine, whereby ink may flow from the outlet 12a on to the roller 3. The nozzle 10 slides across the machine on guide rods 18 which form the lower side of the rectangular frame 6; a handle 9 similarly slides along the upper side of the frame 6, and is so connected to the nozzle 10 by a cable 16 running over pulleys 17a ... 17f, Fig. 5, that the handle and nozzle perform the same movement; the pipe 12 is taken over pulleys 21 and is kept taut by a spring 13. The left-hand end, Fig. 5, of the frame 6 is detachable to allow the rest of the frame together with the parts supported thereby to be withdrawn and changed in multicolour work.

Abstract: 159,838. Corn Products Refining Co., (Assignees of Brindle, R. G.). March 8, 1920, [Convention date]. Surface-tension separating processes and appartus.-In a process and apparatus for separating gluten from starch, the gluten and starch suspended in water are subjected to agitation and aeration for the production of a froth from which the starch is allowed to drain, and the froth of gluten is separated from the starch-containing liquid. The suspension is fed through a pipe B to a vessel A provided with an agitator C and airinlet H. The resulting froth passes down an incline D having a sill E over which the gluten froth passes to a trough F while the starch and liquid pass through an opening 11 to a trough G. Preferably a number of vessels A are used in series, each trough G leading to the next vessel A, wich a common trough F. The starch-containing liquid from the last trough G is treated in settling-vessels K each provided near the bottom with a small agitator 26. The middlings from the settling-vessels may be re-treated in the frothing-apparatus; or part may be withdrawn from time to time and passed over a starch table L. According to the Specification as open to inspection under Sect. 91 (3) (a) the invention is not limited to the separation of starch from gluten. This subject-matter does not appear in the Specification as accepted.
