Title: Improvements in or relating to phase adjusting and/or measuring devices
IPC: H03H7/20
Filed: 1936-12-18
Abstract: 487,338. Impedance networks. STANDARD TELEPHONES & CABLES, Ltd., and BARNARD, R. M. Dec. 18, 1936, No. 34858. [Class 40 (iii)] [Also in Group XXXV] A phase-shifting arrangement which will operate over a range of frequencies comprises a solenoid A with distributed capacity and resistance K to simulate a line, the voltage, the phase of which is to be adjusted, being applied at one end of the line through a variable condenser K1 for adjusting the wavelength of the line, the other end of the line being closed through a resistance R which is adjusted to be equal to the characteristic resistance of the line. When Kl and R have been adjusted to suit the frequency, 180‹ phase shift may be obtained by movement of the contact C along the solenoid. To avoid loading the line the output is taken through a valve amplifier V3. Adjustment of the condenser K1 is effected by means of a valve V1 the grid of which is connected to the centre of the solenoid. The switch S is opened and the switch S2 placed so that the meter M is in the anode circuit of the valve VI. K1 is then adjusted until the meter reading is a minimum. To obtain correct value of R a valve V2 is provided its grid being connected to the output end of the solenoid A. The switch S1 is closed and R is adjusted until the meter reads the same whether it is in the anode circuit of the valve V1 or V2. In a modification two T filters with ganged condensers are used. In this form one of the filters is tapped and only 90‹ phase shift is obtained.

Universal joints.-The intermediate member of an Oldham coupling, modified to allow also tilting and axial movements, comprises an annulus having an inwardly-projecting web with radial slots to receive lugs on the driving and driven members, and provided with an external cylindrical flange extended to form a casing. The coupling may be used to transmit power to the track-wheels or axles of electric locomotives, tram-cars, &c., for example, in the transmission gear described in Specification 291,159. The annular intermediate member 28 has end-discs 44 bearing by rounded edges on rings 42 secured to the flanged coupling members 32, 33 to form a dust tight oil bath, and is centred by leafsprings 45. Lugs 34, 35 on the members 32, 33 slidably engage bearing-pads 31 in slots 30 formed in housings 37, which are carried by a web 29 of the member 28 and may be united at their edges to form a box structure. The web 29 may be apertured for lightness. Lateral flanges 36 on the pads 31 have slots 41 adapted to hook over and depress the ends of cantilever springs 38, which are centrally supported by collars 39 in bores 40 of the housings 37. Recesses 50 in the part 28 communicate with oil-ducts 51 in the pads 31. The pads and lugs may also be bored to facilitate lubrication. The Provisional Specification states that resilient means may be interposed to transmit the torque through or between the coupling elements.

Title: Improvements in foot treatment pads and their manufacture
IPC: A61F13/02
Filed: 1935-12-27
Abstract: 448,610. Corn and bunion shields. SCHOLL MANUFACTURING CO., Ltd., 188, St. John Street, Clerkenwell, London.- (Scholl, W. M.; Chicago, U.S.A.) Dec. 27, 1935, No. 35840. [Class 81 (ii)] A foot-treatment pad comprises a reeess-aper tured body-ring having a bottom fabric coated witladhesive on its underside and a fabric cover-piece adhesively mounted on the body-ring and struc. turally domed above the ring-aperture to increase the depth of the shielding recess beyond that afforded by the ring The cover and body-ring may also be jointly curve contoured in their con nected portions but the body-ring and cover-piece are preferably flat at the rim adjacent to the peri meter of the body. As shown in Fig. 2, an oval pad comprises a cover piece 14 domed at 17 and mounted on a body ring 11, a marginal portion of the pad forming a flat rim 19 to facilitate the mounting of the pad adhesively on a flat carrier strip of crinoline or the like. The body-ring may be made of several layers with interposed films of adhesive. The cover piece and the bottom layer of the body-ring should be of closely woven stretch resistant fabric Cotton-flannel may be used for the intermediate layers. In manufacture, a pre-united multi-ply strip of body stock 11S (Fig. 6) having previously been punched to form the apertures 12 is fed together with a strip of cover-piece stock 14S over a table aperture 40. By raising a centreforming plunger 41 the cover-piece stock is gathered into a hump and by bringing ring members 42 and 43 towards their mating positions the cover-piece is united with the body-stock. Finally by giving a further slight thrust to the plunger 41 the domed portion of the cover-piece is slightly stretched and given a permanent "set." At a subsequent station (Fig. 9) a punch 31 strikes the completed pad through a corresponding die 33 on to a flat carrier strip 20 of crinoline supported on a table 36 after which the crinoline is moved forward and cut into lengths by a blade 37. Preferably, the punch forming the apertures 12 and the punch 31 should both be in the depressed position, extending through the stock while pad-forming operation is performed at the intermediate station shown in Fig. 6. To prevent adhesions the table and plunger (Fig. 6) may be provided with openings for the circulation of cooling medium and the body layer may be given a light under coating of alcohol. To assist the adhesion of the pad to the crinoline, the table 36 may be heated by an electric heater 46.

Abstract: 1404336 Covering cores by winding F CAVALLARIN and G ROSSI 2 Aug 1972 [5 Aug 1971] 36124/72 Heading B8G [Also in Division B5] A method of manufacturing a cylindrical article comprises winding a glued strip 5 of wood or similar material about a core 3 and drawing off the wound strip from the core. In a preferred method the end of a wooden strip 5 is inserted into a slot 15 in the core 3, which is expandible by means of adjustable spokes 16 secured to the driving shaft 19 of a motor 2. A glue trough 6 has a roller urged against the strip being wound by cylinders 10. The motor 2 rotates the core to wind the strip therearound, the strip being braked by a shoe 13 mounted on a spring 14. When a sufficient number of layers have been wound the strip is cut, the core contracted and the article removed. Instead of the spokes 16 the core 3 may be expanded by a pair of co-axial frusto-conical plugs.

Stamping; bending. -Process for making tubes and tubular containers by bending a metal sheet and welding or otherwise connecting the adjoining edges is characterized in that the bending is effected by repeatedly pressing the sheet metal into a semi-cylindrical die proceeding longitudinally from one end of the metal sheet towards the other in the direction of the tube axis. The sheet metal 1 is bent progressively as shown in Figs. 4, 5 and 6 to tubular form by means of a semi-ovoidal shaping die 13 which co-operates with a wooden die 12 supported between girders 10, 11, the die 13 being movable longitudinally beneath a girder 9 attached to the girders 10 and 11 at each end. Alternatively the shaping die 13 may be in the form of a wheel or ball. The edges of the tube may be welded or joined by means of a deformable tubular member 14, e.g. of soft iron or copper, arranged between up-turned edges 2a of the tube and enclosed by a fish-plate 15. The member 14 is deformed by fluid pressure to form a fluid-tight seal as shown in Fig. 8. Finally the tube ends are closed by plugs 4 and 5 held together by a tie-rod 6 and fluid-pressure is passed into the tube to shape it against a die 8. This also tests the tightness of the longitudinal seam.
