Title: Improvements in or relating to recording apparatus
IPC: G01D9/00
Filed: 1934-03-22
Abstract: 438,720. Recording - apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, TURNER, H. C., and NUTTALL, T. C., c/o Salford Electrical Instruments, Silk Street, Salford, Lancashire. March 22, 1934, No. 8978. Addition to 428,028. [Class 106 (iv)] The apparatus of the parent Specification, in which a plurality of interconnect ed driving members coming into operatior successively effects the drive of the recording apparatus according to a non linear law, is, according to the present in. vention, so arranged that each driving member operates the driven member through a friction drive. The driven member consists of an arm 1 secured to the shaft 2 on which is mounted a chart drum. The driving members consist of a plurality of wheels 3 arranged around the shaft 2 with their axes equidistant from the shaft 2. These wheels are geared together so that each wheel is driven at a sub-multiple of the speed of the preceding wheel in the direction shown by the arrows. The wheels may be driven by an operating member such as an electric motor, or the first wheel may be considered as the operating member. Each wheel has a wedge-shaped rim. The arm 1 is made of two phosphor bronze plates 4 separated by a spacer 5. The outer edge 6 frictionally engages the wheels 3 in turn and is thus driven to rotate the shaft 2. The wedge rim is forced between the plates 4 so as to force them apart and obtain the required grip. The edge 6 is so shaped that the desired non-linear relationship is produced between the displacement of the shaft 2 and that of the wheel 3 engaging the arm 1, whilst the gear ratio between succeeding wheels is such as to maintain the continuity of the relationship as the arm passes from wheel to wheel. Each wheel is first engaged by the leading end 7 of the edge 6 at a point near the periphery of the wheel and the point of engagement approaches the axis until finally the trailing end 8 engages the wheel at a point near its axis. Specification 427,989 is referred to.

Title: Improvements relating to Surface Treatments for Porous Plastics Materials.
Inventor: HULL GRAHAM RODNEY
IPC: C08J9/36
Filed: 1966-03-07
Abstract: 1,190,551. Porous polymeric material. PORVAIR Ltd. 2 May, 1967 [7 March, 1966], No. 9976/66. Heading B2E. [Also in Division C3] A grain leather-like appearance is imparted to the surface of a body having a surface zone of porous polymeric plastics material e.g. microporous polyurethane, by bringing a solvent e.g. N, N'-dimethyl formamide, for the plastics material in a finely divided state into contact with the surface, the structure of the remainder of the body not being significantly effected. A grain leather-like appearance may be imparted to a surface of a flexible water vapour permeable body including a microporous surface zone of soluble polymer substantially all of the pores opening through the surface having no dimension in the plane of the surface greater than 100 microns by depositing solvent for the polymer on the surface in finely divided liquid form and heating the surface to remove the deposited solvent to' produce a water vapour permeable material having an increased resistance to the ingress of liquid water through the treated surface. The solvent or solvent composition is sprayed on to the surface; the spray being directed at the surface and traversed back and forth across the surface whilst the surface moves transversely to the direction of spraying. A current of air, which may be heated to between 40 and 100C. may be blown across the surface between the surface and the source of the spray. The surface may be coloured and may be darkened and made less matt by the solvent in finely divided form having substantially all of the droplets of diameter between 1 and 30 microns when they contact the surface; between 60 and 70% of the droplets may have diameters of 1 to 10 microns. The spray may be formed by means of air under a pressure between 15 and 30 Ibs/square inch. The microporous surface zone may be made by coagulating a solution of polyurethane with a non- solvent; or from a solution of polyurethane having dispersed therethrough three parts by wt. of microscopic removable solid filler per part by wt. polyurethane by coagulation with a non-solvent which removes the solvent and the filler. As exemplified, the body may be needle punched nylon felt into which polyurethane is precipitated, and which has been split into sheets the smooth surface of which is doctor knife coated with a polyurethane composition containing removable filler e.g. sodium chloride, dried, further doctor knife coated with a polyurethane composition containing removable filler, immersed and then washed with water and dried. The body is sprayed with dimethylformamide or cyclohexanone, which may contain lacquer working material such as polyurethane. The porous plastics may also be made by a melt-roll coating process.
