Patent GB-570696-A (GB)
Title: Improvements in and relating to the treatment of textile fabrics
IPC: D06M15/423
Filed: 1943-10-28
Abstract: Raised fabrics of improved appearance and handle are obtained by impregnating the unraised fabrics containing fibres of cotton, wool, regenerated cellulose or casein, with an intermediate resin or resin forming components, e.g. cyanamide-formaldehyde, urea-formaldehyde, or glycerine-phthalic anhydride, subjecting the fabric to a raising operation and heating to insolubilize the resin.  The resin may be applied to the unraised woven or knitted fabric, and either before or after dyeing, or it may be applied to the thread or staple fibre before its conversion into fabric.  In the examples: (1) viscose rayon fabric is impregnated with a solution containing a urea-formaldehyde precondensate and boric and lactic acids, dried, raised, heated at 135 DEG  to 140 DEG  C., and finally treated with live steam to remove residual formaldehyde; (2) viscose rayon fabric is padded with a liquor containing formaldehyde, cyanamide and ammonium thiocyanate, dried, damped and raised, dried and heated at 140 DEG  to 150 DEG  C.  A softening agent, e.g. sodium cetyl sulphate, may be added to the impregnating solution of either example.  Specification 506,793 is referred to.

Filed: 1929-06-10
Abstract: 316,292. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. July 27, 1928, [Convention date]. Filaments. -- To enable a more concentrated arrangement of filament to be obtained without risk of disruptive discharges, especially in gas-filled bulbs, it is divided into a number of parts of concentrated form which are connected in series and arranged in pairs so that their ends are opposite each other, one end of one part in each pair being connected to the remote end of the other part, the potential difference between opposed ends of the parts thus being much less than the supply voltage. The filament may be of the doubly-wound helical kind. When the filament is arranged in three straight parallel sections as shown in Fig. 2, the potential difference between opposed ends is only one-third of the supply voltage, and when it is arranged in two parts. lying in a circle as shown in Fig. 6, the potential difference is one-half of the supply voltage.

Title: Improvements in fluid control valves
Inventor: EATON MAURICE BARRY
IPC: F16K31/385
Filed: 1962-05-12
Abstract: 972,052. Valves; fluid pressure brakes. GIRLING Ltd. April 16, 1963 [May 12, 1962], No. 18361/62. Headings F2F and F2V. A valve for controlling the supply and exhaust of fluid to a braking system comprises a valve head 19, Fig. 1, movable between aligned seats 18, 21 to control the supply and exhaust of fluid to an outlet 12. The valve head is provided with extensions 35, 37 of a diameter slightly smaller than seats such that when the valve head moves towards either seat, flow through the seat is throttled prior to valve closure.

Title: Transmission ratio control system
IPC: B60W10/00
Filed: 1976-05-05
Abstract: 1496475 Hydrostatic transmission control SUNDSTRAND CORP 5 May 1976 [8 May 1975] 18380/76 Heading F2W The transmission ratio of a hydrostatic transmission 14 driven by an engine 10 is adjusted by a ratio control valve 50 which is biased by a signal proportional to engine speed in opposition to a signal, responsive to main line pressure in the transmission, proportional to engine torque so as to set a certain engine speed for each value of torque to maximize fuel economy. In the embodiment shown in Fig. 1 the ratio control valve 50 has a spool 51 acted on by pressure in a line 62, a valve 55 being controlled by flyweights 56 such that this pressure is proportional to speed. The opposite end of valve spool 51 is acted upon by the main line pressure in the transmission 14 via an actuator 83 and a lever 70, the position of the actuator relative to the lever being varied in dependence on the pump 16 swashplate position, through linkwork 27, 84. The engine torque is a function of transmission pressure and swashplate position and the arrangement is such that the lever 70 acts on valve spool 51 with a force proportional to engine torque. Movement of the valve spool 51 from the equilibrium position shown supplies pressure from a line 63 to either of a pair of control cylinders 25, 26 to adjust the transmission ratio until the equilibrium position is regained. A pedal 102 provides engine braking by adjustment of a valve 100 to supply fluid under pressure from a port 105 through a line 106 to the actuator 83 to modify the transmission ratio to increase engine speed. The pressure in line 63 which adjusts the transmission ratio is controlled by a variable relief valve 64 in dependence on engine speed so that at low engine speeds (less than 50% of rated speed) this limits the displacement of the pump 16. In an alternative embodiment, shown in Fig. 4, the main line pressure acts directly on one end of valve spool 51 in opposition to the speed responsive pressure and a spring 119 whose bias is varied by a cam 115 associated with the pump swashplate 24 through linkwork 110, 111. The combined effects of spring 119 and the main line pressure provide a bias proportional to engine torque which acts in opposition to the speed signal. The transmission may be in a tractor or truck.
