Title: Improvements in and relating to the waveguide transmission of electromagnetic waves
IPC: H01P1/18
Filed: 1945-07-10
Abstract: 608,494. Electric resonators. JOHNSON, W. A., RAWLING, A., and CULLEN, A. L. July 10, 1945, No. 17641. [Class 40 (viii)] [Also, in Group XL (c)] A wave-guide has a plate or rib of conductive material projecting into the guide substantially in the plane of the electric field so as to modify the effective length of the guide and thereby shift the phase of wave energy propagated through the guide. In Fig. 1, a conducting plate 1 may be inserted to a variable degree into a rectangular guide carrying a transverse electric wave through a slot 2 formed with quarter-wave chokes 3 to reduce leakage. To minimize sparking, the lower edge of the plate is not permitted to approach closely the lower wall of the guide, and the lower edge of the plate may be rounded or protected by insulating material. The lower corners of the plate 1 may be chamfered or the plate may taper from one end to the other to reduce mismatch. In Fig. 3, the plate 1, which has rounded edges to reduce sparking and increase mechanical strength, can be cyclically inserted and withdrawn from the guide by insulating radius rods 5 on a shaft 6. The guide has a series of antenna slots 4 or the equivalent, the unit being used for producing an oscillating beam of radiant energy. In Fig. 4a, the vanes are in the form of radial ribs d, f on a conducting cylinder e which rotates close to extension walls h, i of a wave-guide a, b, c. Thus, in the position shown, the guide walls are completed by ribs d, e and the circumference of the cylinder between them. When the cylinder is rotated so that one of the ribs projects into the guide, the ribs on either side serve to complete the guide walls. By rotating the cylinder continuously, a repetitive phase shift is introduced. Alternatively, two cylinders may be used on opposite sides of a rectangular guide (Figs. 6a, 6b, not shown). The ribs may be in the form of ridges along a rotor having a starshaped cross-section (Figs. 5a, 5b, not shown). Fig. 7a shows a form in which the rotor runs gradually into a wave-guide from the lower end where the guide is separated from the rotor which, at this point has a circular cross-section, to the upper end where the rotor has a ribbed cross-section, Fig. 7b. Specification 589,603 is referred to. Reference has been directed by the Comptroller to Specification 617,381, [Group XL (c)].

Abstract: 709,069. Operating clutches. PILLMAN, A. H. July 25, 1951, No. 17683/51, Class 80 (2) [Also in Group XXX] A driving mechanism for double drum scraper winches includes the combination of a driving shaft, a gear thereon meshing the driving gear of the winch drum, a friction clutch to lock the former gear to the high-speed shaft and means operated by a control lever for applying a force to hold the dutch in engagement, said force being independent of the force exerted by said control lever. As shown, a driving shaft 1, Fig. 1, is connected for rotation with gears 2, 3, meshing gears on the drum shafts, through plate clutches 4, 5 alternatively engaged by a pivoted lever 6 pulled to one of its two operative positions by a spring 8. In modifications, Figs. 2, 3 (not shown), the clutches are engaged by servo meams. In a further modification, Fig. 4, a sleeve 16 between the clutches. 4, 5 is axially slotted to receive levers 18, pivoted at 19, having toe portions 20 which urge the clutches into engagement when the levers fly out under centrifugal force, a collar 22 surrounding the sleeve and levers 18 and being moved axially by the pivoted control lever 6 to prevent one or other of the levers from flying out.

Abstract: 513,377. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and ARMAN, A. N. June 14, 1938, No. 17701. [Class 36] A high-tension cable comprises a conductor 1 surrounded by inner and outer layers 2, 4 of laminated dielectric which are separated by an impervious envelope 3 consisting solely of insulating material, the inner dielectric layer being maintained under pressure (e.g. a pressure of between 150 and 300 pounds per square inch) by compressed gas, such as nitrogen or carbondioxide, contained within the envelope 3. A metallic screen 5 and a lead or like outer impervious sheath 6 complete the cable. The inner dielectric layer may be of dry or preimpregnated paper, the interstices of which are filled by the compressed gas ; or oil-impregnated paper may form the inner dielectric layer, the envelope 3 being a loose fit on the layer to provide a space in which the gas is accommodated. The envelope 3 may be formed of rubber, "Neoprene" or other oil-resistant rubber-like compositions, cellulose products, such as benzyl cellulose or cellulose acetate, or of polyvinyl chloride resins, such as those known under the registered Trade Marks "Mipolam," "Igelit" and "Koroseal." The envelope maybe applied by extrusion, or by lapping the inner dielectric layer with thin tape, the turns of which are subsequently coalesced by heat. The outer dielectric layer 4 may consist of oilimpregnated paper, varnished cloth or paper, cellulose acetate, or acetylated or esterified paper. Specification 439,575 is referred to.

Abstract: 636,616. Rolling. AETNA-STANDARD ENGINEERING CO. July 4, 1947, No. 17736. Convention date, May 24, 1946. [Class 83 (iv)] [Also in Group XXXIV] Mill rolls 1 are adjusted axially by means of a screw 59 which moves a sleeve 43 containing one end bearing R<SP>1</SP> axially in its bearing block 9, the bearing block 10 at the other end being free to slide axially in the frame. The bearing blocks 9, 10 are adjusted vertically, relative to an identical assembly below, by any known means, both assemblies sliding between vertical guide faces 11-14 of the frame, the bearing block 9 being restrained from axial movement in the frame by guide plates 66, 67. One end of the shaft 8 on which the roll 1 is taper fitted and keyed runs in the bearing R held in position thereon by sleeves 23, 32 and nuts 25, 33 and in the block 10 by flange 29 so that axial movement between the shaft and block is prevented. The other end of the shaft runs in a similarly fixed bearing R<SP>1</SP> axially held by a flange 44 in a sleeve 43 which is axially slidable in a bore in the bearing block 9. An adjusting screw 59 mounted on the end of the sleeve 43 by the cap 46 is actuated by a nut 64 on a detachable yoke 50 which is secured to the bearing block 9 by pivoted screws 53, 54 in slots 51, 52. A flange 49 on the sleeve 43 engages a shoulder 48 on the block 9 to limit axial movement of the shaft and roll. The rolls may be mounted horizontally, vertically or in an inclined position, and the guides 66, 67 are slotted at 70 to allow rapid removal from the studs 68. Operation. To adjust the roll 1 axially, the nut 64 is turned, moving the sleeve 43 axially in the bearing block 9 and carrying with it the shaft 8, the bearing R and block 10 sliding axially between the faces 13, 14 of the frame. After adjustments the screw 59 is locked by a nut 65.

[Class 103 (iii).] In a device for cleaning grooved tramway &c. rails, longitudinallyarranged beams carrying a scraper 20 at each end are freely mounted on a shaft 8 driven from the vehicle wheels by gearing 10, 9, 3, 5, 4 and a clutch 6, 7 controlled by the driver, friction discs 11 mounted above the rails being keyed to the shaft 8, and each beam being pressed by springs 13 into contact with one of the discs so that when this disc rotates the beam will rotate until the scraper at one end engages the rail after which the disc slips relatively to the beam. Each beam is in two parts each comprising a disc-shaped member 12 for engaging the disc 11 having an arm 15 connected by a helical spring 16 to a rod 17 formed at its end into a bracket 19 to which a forked member 21 is pivoted at one end and pulled by a spring 22 into contact with the bracket at its other end. The scraper 20 is adjustably secured by a pin passing through the member 21 and through one of several holes 201 in the scraper.
