Title: Improvements relating to reflectors
IPC: F21V7/22
Filed: 1941-02-20
Abstract: 540,480. Reflectors. MOND NICKEL CO., Ltd. Feb. 20, 1941, No. 2329. Convention date, Feb. 26, 1940. [Class 97 (i)] [Also in Group XXXVI] In producing reflectors such as reflectors for searchlights and submarine mirrors, a matrix is first prepared by the electrodeposition on the concave surface of a glass mould 21, Fig. 13, of a layer of silver 22 followed by a thicker layer 23 of copper, applying a stop-off layer 24 of lacquer &c. and stripping the whole from the mould. On the convex surface of the matrix so formed a layer 25, Fig. 18, of rhodium is deposited followed by a thicker layer 26 of gold, platinum, or palladium, or an alloy of these metals. Over the last-mentioned layer a thick supporting layer 27 of copper or nickel is applied and covered with a stop-off layer 28 of lacquer &c. Stop-off layer 24 is now taken off and the silver and copper layers 22, 23, removed by nitric acid or by electrolysis, to produce the mirror shown in Fig. 20.

Title: Improvements in or relating to reel rewinding apparatus

Abstract: 696,285. Unwinding and winding webs; inkribbon mechanism. BLOCK & ANDERSON, Ltd. April 30, 1951 [Jan. 30, 1950], No. 2389/50. Classes 100(i) and 100(iv) An arrangement for rewinding a web, e.g. of carbon paper, which passes over a roller, platen or the like, comprises a driven supply roll and a rewind roll between which a loop of the web passes over the roller, platen or the like, and a disconnectable driving connection between the supply and rewind rolls, said driving connection being controlled by a movable feeler member arranged to deflect the path of the web to the rewind roll, such that the position of the feeler member is dependent on the web tension. As applied to a carbon paper feed roll attachment device for a typewriter, the carbon paper x, unwound from a spool supported at one end by a rotatable stub shaft 24 and at the other end by a similar but axially spring-pressed stub shaft, is passed around the typewriter platen roller and over a rod 56 and is then rewound on a second spool carried by a similar pair of rotatable stub shafts. The spring-pressed stub shafts permit the ready removal of the spools. The rod 56 is carried by a pair of pivotally mounted arms 55, such that an increase in tension of the paper x during winding causes a roller 57 on the rod 56 to engage an arm 37 of a bell crank lever 34 so as to lift a rotatable coupling roller 32 having a frictional surface out of engagement with two wheels 27 and 29 having frictional peripheries. The wheels 27 and 29 are fixed to the stub shafts supporting the unwind and rewind spools at one of the ends. The unwinding of carbon paper from the unwind spool caused by rotation of the platen roller during advancement of the work causes winding of the winding spool when the roller 32 drivingly contacts the wheels 27 and 29, the roller 32 normally being held in contact by a weight 40, and/or by a spring. A pair of end frames carrying the stub shafts are readily attachable to the back plate 11 of the typewriter by screws 18, the plate 11 being extended by an extension plate 21. For attachment to various sizes of machines the rod 56 mav be telescopic. The attachment may be applied to adding machines, teleprinters, tabulators and accounting machines which employ a platen or other roller by which work is fed and in which carbon or like paper is used. Specification 466,720 is referred to. According to the Provisional Specification the arrangement may be utilized for rewinding a typewriter ribbon.

Abstract: 1,065,103. Making finned tubing; coiling helices. TUBE PRODUCTS Ltd. March 15, 1966 [Jan. 20, 1965], No. 2444/65. Headings B3A and B3E. Helically finned tubing for use in a heat exchanger is produced by welding a fin forming strip 10 to a tube forming strip 11 to form a composite strip of T-section, and then helically coiling the strip 11 and welding its contiguous edges to form a tube. The initial welding of the two strips can be high frequency contact resistance welding, and the coiling is performed using conventional or suitably slotted guide rollers. The strip 10 can be slotted or slitted as at (14) (Fig. 3, not shown) to produce fingers (16). More than one strip 10 can be welded to the strip 11 to produce multiple fins, or the strip 10 can be inclined to the length of strip 11 to form a helical fin of different pitch from that of the tubing. The metals of the strips may be different from one another.

Title: Process and apparatus for the production of road surfaces and foundations for railway tracks

Filed: 1932-02-01
Abstract: 397,882. Ramming road material. WALDVOGEL, H., Wollerau, Schwyz, Switzerland. Feb. 1, 1932, No. 2973. [Class 124.] A method of making road coverings, or foundations for railway tracks, with gravel, sand, or like material and a binder, such as cement or bitumen, comprises ramming the material beneath a template corresponding to the finished road or foundation surface by means of compressed air ramming tools. In the device shown in Fig. 14, a pair of tools 63, arranged at each end of the machine, carry between them a ramming plate 68. The two tools 63 are pivoted at 62 on a frame 60, which also carries a hopper 61 and an air compressor 67. Material is deposited on to the ground when the tools are withdrawn by means of a lever 72. The machine is moved forward by the action of an arm 73 on the lever 72, engaging the plate 68 and pressing the latter against the material previously rammed. The arrangement of the compressor on the machine ensures that the vibrations of this member provide the necessary vertical ramming of the material. In an alternative arrangement, the rammers are carried on a travelling frame 87, 91 mounted on rollers 89 as shown in Fig. 18. The template 92 is formed in a number of sections, each of which is pivoted at 93 to the frame 91 and is suspended by a hook 94 on a bar 95 of the frame 91. A hook 96 pivoted on the ramming tool 97 is also supported on the hook 94. The material is forced under the templates 92 by means of the hand-controlled rammers 97 and the vibrations of these rammers are also transmitted through the hooks 96, 94 on to the templets in order to provide the vertical ramming of the material. To enable the machine to be moved forward, the forward part of the machine is adapted to be supported on a roller 90 which is mounted in a slot in a lever 102 pivoted to the frame 87. A pivoted lever 103 is adapted to be moved into alignment with the lever 102 to depress the roller 90 and cause it to support the frame when the machine is to be moved. During the ramming operation, the hook 94 is disengaged from the bar 95 of the frame.
