Title: Improvements in or relating to spraying apparatus
IPC: B05B3/08
Filed: 1947-03-31
Abstract: 622,587. Sprayproducers. NORRIS, E. O. March 31, 1947, No. 8619. Convention date, April 3, 1946. [Class 69 (iii)] A high-speed series type motor within the housing 1, drives a collecing case 11 inside the casing 5 at approximately 10,000 r.p.m. Paint or other liquid to be sprayed is fed by gravity or pressure into the collecting case where it is spread out into a thin film, by centrifugal force, on the interior wall of the collecting. case. A rotatable distributer 20, which comprises two flat discs 22, 25, with shallow rims 23, 26, is mounted close to the interior wall of the collecting case 11, as shown in Fig. 3, and makes contact with the paint film and is rotated thereby, causing a finely atomised spray of paint to be projected through the opening 14 in the front of the collecting case. The paint enters a chamber 48 from container 63, via supply pipe 61 and a control valve 57, Fig. 8, which is actuated by a trigger control 64. From the chamber 48 paint flows forward into the rear chamber 16 of the collecting case, where it is fed by centrifugal force through passages 18 on to the interior wall of the collecting case. The rotary distributer 20 is mounted on a shaft 31 which is rotatably supported in a bearing sleeve 32 and permitted to move axially within the limits of travel of the nut 40 in the sleeve 34. When paint reaches the wall of the collecting case it makes contact with the rim 23 of the rotary distributer and pushes it back against the spring 43 within the hollow bore 39 of the shaft 31, when the paint supply is cut off the rotary distributer is returned to its former position by the action of the spring 43. The action of the rotary distributer in addition to sending a band of spray through the opening 14 in the collecting case causes extensive agitation of the paint film and prevents separation of the paint into its constituent parts, oil, pigment, &c., by the centrifugal action. In a modification, the movement of the rotary distributer into the paint film, is accomplished by mechanical rotation of an eccentric bush 76, Fig. 8, by a mechanical link 82 from the actuating trigger controlling the paint supply.

Patent GB-1028450-A (GB)
Title: Webs of thermoplastic polymeric materials
IPC: B29C48/355
Filed: 1965-03-02
Abstract: A process for preparing a web of a thermoplastic polymer, which resembles a non-woven fabric, comprises melt-extruding a film of a foamable composition of the polymer under conditions such that foaming takes place to give a product with closed cells. Thereafter, this product is treated to rupture at least 50% of the closed cells, the said treatment comprising stretching the foamed film, or heating it to cause shrinkage, whilst restraining shrinkage. It is preferred that the extrusion takes place through an annular die, such that it can be expanded by an internally-applied fluid pressure.  A fluid-impervious backing which contacts at least a portion of the extruded film permits further rupturing of cells and expansion by restricting the flow of the fluid through the ruptured cells. Suitable apparatus is illustrated in Fig. 1 (not shown), in which 12 is the annular die, the fluid pressure is applied through pipe 16, and 20, 20A are the fluid-impervious backing.  The invention is suited to polyvinyls and polyolefines, but any thermoplastic polymer may be used, e.g. polyurethanes, polycarbonates, cellulose acetate, polyamides. Any conventional chemical or physical blowing agents may be used.

Title: Improvements in fuel-feeding devices for furnaces
IPC: F23K3/00
Filed: 1920-03-26
Abstract: 140,819. Holbeck, A. A. Dec. 27, 1913, [Convention date]. Fuel, feeding.-Pulverulent fuel is fed from a hopper 9 by a screw conveyer 12 on to a rotary table 15 driven by an electric motor 17, and is swept off the table by a fixed plate or wiper 24 into the suction conduit 21 of the fan 20. The fuel is delivered by the fan through a distributing- pipe 25 communicating by means of pipes 27, each provided with a manually-operated valve 30, with furnaces such as 5. Surplus fuel is returned through a pipe 29 to a collector 18 from which fuel escapes through the discharge pipe 19 to the hopper 9. Air is withdrawn from the collector 18 by a pipe 34 connected to the suction pipe 21 of the fan. The speed of the motor 17 is automatically regulated by a controller 44 provided with an arm 43 connected by a rod 42 and lever 36 to a rod 37 from which is suspended a float 38 arranged within a cage 39 depending from the suction pipe 21 into a well 40 containing liquid. Any variation of pressure in the pipe 21 caused by opening or closing the valves 30 for varying the feed to the furnaces thus causes a variation of the level of the liquid in the cage and affects the speed of the motor.

Abstract: 1536204 Ignition systems LUMENITION Ltd 1 March 1977 [5 March 1976] 09020/76 Heading F1B The speed of revolution of an I.C. engine having an ignition coil providing spark ignition is limited by means of a semi-conductor breakdown device, e.g. Zener diode 24, and a series connected semiconductor switch, e.g. Darlington pair PD, arranged between the terminal B connected to the primary winding of the ignition coil and earth, and operable, (by biasing the switch to be continuously conductive when the speed exceeds a predetermined value), to limit the voltage developed in the primary winding to a voltage equal to the breakdown voltage of the Zener diode 24 and hence to prevent ignition. As shown, a chain of inverse switching transistors T1 to T4 is controlled by the pulses from the coil on operation of an ignition semi-conductor switch to switch the Darlington pair on and off for normal operation. A delay circuit Cl, Z2 prevents operation of transistor T2 if the ignition pulses are too close together signifying excessive speed, to leave the PD conducting continuously. Again, Fig. 3 (not shown), a Schmidt trigger may replace transistor T2.
