Patent GB-822025-A (GB)
Title: Pipe coupling
Inventor: DORRICOTT WILFRED GEORGE
IPC: F16L23/08
Filed: 1956-02-25
Abstract: 822,025. Pipe couplings. TALBOT-STEAD TUBE CO. Ltd. Feb. 25, 1957 [Feb. 25, 1956], No. 5956/56. Class 99(1). [Also in Group XXV] Flanges 12 on pipe ends 10, 11 are drawn together by clamping means 14 and compress a resilient sealing washer 13 received in shallow concentric recesses 15 in the opposed ends of flanges 12 of which the peripheral portions 16 receive an external rib 17 of the washer 13. The dimension of the washer 13 in its free state from each end face 18 to the face 19 of the rib is equal to the depth of the recess 15 so that the flanges engage the related faces of the washer simultaneously and the rib 17 is more tightly compressed than the main portion when the coupling is tightened. As described the flanges are fixed to the pipes by providing internal circumferential grooves 20 into which the material of the pipe and walls is expanded. The peripheral rib 17 is approximately half the thickness of the main portion of the washer and in its free state projects radially a similar amount or less. The clamping device 14 comprises two semi-circular members hinged together at one end and tightened by a tangential clamping screw at the other. The outward faces 25 of the flanges are conoidal and are engaged by complementary shaped walls of the recesses 26 of the clamping members which are of arcuate shape extending along the middle parts only of the clamping members so as to engage the flanges on opposite sides of the pipe. When the clamping screw is tightened the sealing ring 13 is compressed and its bore tends to bulge inwards thus avoiding the formation of crevices. The pipe may be of stainless steel, the ends projecting beyond the flanges and finished flush.

Title: Method of coating a porous cathode body with osmium
IPC: H01J9/04
Filed: 1968-02-07
Abstract: 1,145,967. Cathode materials and processing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 7 Feb., 1968 [10 Feb., 1967], No. 6058/68. Heading H1D. [Also in Division C7] Porous W cathode bodies having Ba compounds in their interiors are coated with Os by heating in an H atmosphere and so reducing Os oxide. Os oxide may be vaporized by heating and brought into contact with the bodies, which are at at least 300‹ C., so that Os coatings form on them, or Os oxide coatings may be formed on the bodies and reduced by heating in H to at least 300‹ C. The Os oxide coatings may be made by immersing the bodies in a solution of Os oxide, such as an ammoniacal aqueous solution. High-frequency heating may be used to heat the W bodies and where Os oxide is vaporized a crucible containing it may be heated by a surrounding resistance heating coil.

Title: Improvements in the construction or manufacture of boots and shoes
IPC: A43B9/06
Filed: 1925-03-05
Abstract: 257,963. Shoe Inventions, Ltd., and Rice, F. E. March 5, 1925. Lasting, methods of; welts; connecting uppers td insoles and soles. - A method of shoe manufacture includes the use of a templet to which a welt is temporarily attached for positioning and securing to the shoe, is characterized in that means are provided in the templet, such as rebating, marking, or holeing whereby the position of the welt is determined thereto. A preferred method of lasting, not claimed per se but only in combination with the use of the above templet, consists in attaching an insole B, Fig. 3,.to a last A with a templet T<1> attached to the forepart on the last. An upper D is then lasted on with the edge abutting the templet T<1>. The toe is held by a binding wire and tacks (not shown). The edge of the upper is then secured by leather strips F which may, or may not, be removed later. A welt L, Fig. 4a. is then solutioned to a rebated templet T<4> in a groove 4<a>. This templet is then tacked to the first templet T<1> to coincide with it as in Fig. 4. The shoe may now be removed from the last and the welt sewn on, the edge of the templet acting as a guide. The shoe is then relasted and both the templets removed and a bottom filling added. The shoe now has a flat bed for soleing. A preferred form of welt is shown at L, Fig. 6, where the welt is wedge-shaped and split at L<2>, stitches L<1> securing it to the upper being laid in the channel L<2>. The channel is afterwards closed down. In place of the rebate 4a, Fig. 4<a>, in the templet T<4>, a line of markings or holes t<3>, Fig. 5, may be used and these holes may also be used to secure the upper templet to the lower one T<1>. The edge of a welt M solutioned to the templet may be scolloped to aid bending. The templet may be reinforced by a metal border t<1> and by a steel waist piece N. It is stated that welted shoes with crepe rubber outer soles and crepe welts, reinforced with canvas or the like, may be made in this way with advantage. Specification 248,409 is referred to.

Abstract: 739,954. Valve amplifying circuits; transistor amplifying circuits. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. March 2, 1954 [June 26, 1953], No. 6163/54. Class 40 (6). A distributed line amplifier is divided into two or more sections (5, 6, 7, 8) the input and output of each of which is connected to the input and output respectively of the next through phase reversers 9, 10. The latter may be transformers having series inductors to compensate for the shunt capacitance of the transformer or valve phase reversers. When the valves of the amplifier are biased for class B operation by the use of the invention the distortion in one section may be balanced out by that in the next in the manner of the conventional push-pull circuit (Fig. 1, not shown). The valves may be replaced by transistors.

Abstract: 990,409. Printing-machines. ACCOUNT)- TOKENS Ltd. Feb. 19, 1963 [Feb. 19, 1962], No. 6312/62. Heading B6C. A printing machine comprises a base-plate 1, a printing-head 8 pivoted to the base-plate, an inked impression roller 9, a manually operable lever 11 to move the roller along the head, and means to latch the head tightly against the baseplate, one part 17 of the latch means being mounted on the pivoted head and the other part 20 being mounted in the base-plate, the two parts being adapted to release the head from the base-plate at the end of the printing stroke of the roller along the head. In operation a plate 3 carrying embossed information, such as a name and address and a code number, is located on the base-plate beside date wheels 6 and a plate 5 carrying for instance the name and address of an issuing authority. At least one record sheet is then located by flanges 7 on the base-plate and the head 8 is depressed by pulling the lever 11. This first movement pivots the head against a spring 15 until the head abuts a screwthreaded adjustable post 16 whereupon the hook member 17 latches with the part 20 which is in the form of an adjustable eccentric rod. Further movement of the arm 11 moves a link 12 causing the roller 9 to be moved along the head in guides 10 to effect printing on the record sheet. At the end of the travel of the roller 9 its supporting fork 13a engages a bell-crank part 18 of the latch member 17 so that the latch is released and the head 8 returns to its initial position under spring action.
