Title: Process for obtaining quilted foam-to-fabric laminates
Inventor: MCCONNELL ALBERT LAWRENCE
IPC: B29C44/00
Filed: 1968-01-23
Abstract: 1,215,503. Quilted laminates. SCOTT PAPER CO. 23 Jan., 1968, No. 3617/68. Heading B5N. A method of making a laminate comprises applying a non-combustible liquid to certain part of the surface of a sheet of foamed plastics material to obtain selected masked and unmasked areas, activating the surface with flame treatment to render the unmasked areas adhesive, contacting the surface with a fabric sheet and laminating under pressure. The masked areas may be spaced diamond-shaped areas, Fig. 2 (not shown), to produce a quilted laminate. Alternatively, the masking fluid may define squares, stripes or dots on the foam sheet. The liquid may be applied by a printing operation, e.g. by transfer from small diamondshaped areas on the outer periphery of an engraved roller (10), Fig. 1 (not shown), or by brushing or spraying. The liquid may be water, to which a wetting agent may be added and its viscosity may be increased by adding agents based on either colloidal silica or carboxymethyl cellulose. The foamed plastics sheet may be of polystyrene, polyethylene, polypropylene, polyurethane or p.v.c. The fabric sheet may be of cotton, rayon, nylon or muslin. The treated surface of the foam sheet (4) may be activated by a burner (14) immediately before passing, together with the fabric sheet 18 through the nip between two rolls (20) and (22), Fig. 1 (not shown).

Title: Improvements in and relating to the extraction of extranecus material from fluids or gases
IPC: B01D45/06
Filed: 1927-02-09
Abstract: 289,192. Gordon & Co., Ltd., J., (Hagan Corporation). Feb. 9, 1927. Density separators. - Extraneous material is extracted from a stream of gaseous fluid centrifugally and is carried away by a thin liquid film moving constantly along a collecting surface in the direction of the flow of the stream. The apparatus is shown in Fig. 1 as a steam separator secured inside the boiler f and having a casing a with an annular steam inlet provided with vanes d to give the entering steam a whirling motion. The outlet port c contains a cylindrical member h, preferably with a machined surface. located so as to provide an annular gap l between it and the edge of the discharge conduit m. The end of the member h is flared and its outer surface is tapered away from the gap to the point l<1>. Steam enters the annular port; impurities and water are deposited on the casing a and are carried away by the pipe g. When the fluid leaves the casing a it deposits moisture on the member h and owing to the nature of the surface of the member, the moisture spreads as a thin film; it is subject to the entraining action of the rapidly-moving fluid stream, and carries upwards with it any deposited impurities. The construction of the upper end of the member h tends to prevent the film from breaking as it passes over the upper edge and down to the point l<1>. The separated liquid collects in the chamber and is discharged through the pipe k<1>. In a modification, the outlet h is arranged above the casing a. In this form the casing a is arranged inside the boiler and the outlet h outside the boiler. In another modification shown in Fig. 2, the separator is constructed for connection in a steam main. Steam enters the annular port b<1> from the flanged entry g<1> and passage g<2>, the latter of which partially surrounds the secondary stage of the separator. The matter collected by the member h<1> is passed into the chamber j' and is discharged through the pipe u while the steam is passed into the discharge pipe r. An annular row of inlet apertures may be provided near the bottom of the member h for the introduction of liquid to form the film where the material undergoing separation contains insufficient liquid for the purpose.

IPC: F16H61/44
Filed: 1958-02-05
Abstract: 887,194. Valves. HYDRAULIK A.S. Feb. 5, 1958, No. 3753/58. Class 135. A pressure-responsive valve has an inlet closure formed by cylindrical port 141 and a larger cylindrical port 142 respectively tightly slidably fitting cylindrical openings 145, 144, port 141 having its opening before port 142 opens passage 144, means being provided to supply fluid to the face of port 142 to prevent a vacuum forming during opening. The pressure-responsive valve has an upper chamber 102 with a fluid outlet 83 and a pressure fluid inlet 80 and a lower chamber 103 having a fluid inlet 84 and outlet 85, and a cylinder 109 of smaller cross-sectional area than and in axial alignment with the first inlet, a valve member 111 having a first land 112 for closing the first inlet, a second intermediate land 114 for closing the opening 108 between the chambers and a third land forming a piston 115 in the cylinder 109, a bore 140 extending axially through the valve from the first to the third land, and an adjustable compression spring 119 urging the first land to close the first inlet and the second land to be spaced from the opening 108. Pressure from pump 2 controlled by valve 3 acts via 13 to drive a motor 10 connected on the same shaft as a motor 82 across the pipes 83, 84 to which the pressureresponsive valve is connected as a by-pass valve. With the valve open, motor 10 drives motor 82 as an unloaded pump circulating fluid through the open by-pass valve. When the load on motor 10 is sufficiently high the pressure in 13 acts via inlet 80 to move the small cylindrical port 141 down sufficiently until the pressure acts on the larger port 142 to quickly open the inlet and close the opening 108 so that pressure now drives the motor 82. Valve 114 closes opening 108 slightly before the inlet is fully opened. Suction at the shoulder between the two cylindrical portions 144, 145 is relieved by notches in the periphery of disc 142. Valve 114 is guided into opening 108 by recesses 147 on the lower face of the valve and the third land 115 is provided with a plug 148 forming a buffer with casing 109, 149. Specification 774,315 is referred to.

[Also in Division B7] Electrically-propelled storage carriages 1a- 1d are movable between fixed end-positions with means to provide a service passage between the carriages. The drive motor of each carriage is supplied from pairs of conductors 2a 1 , 2a 2 -2d 1 , 2d 2 , through trolleys 3a-3d, the polarity of each conductor-pair being reversible by units 4a-4d. Double-pole switches 9a-9d have their positions determined by the direction of travel of the carriages, and couplings such as 10a 1 , 10b 2 , are adapted to interconnect the control circuits of adjacent carriages. Actuation of push-button 8c causes the unit 4c to reverse the polarity of conductors 2c 1 , 2c 2 , so that the carriage 1c is driven towards the left. If the push-button 8d is pressed, both carriages 1c, 1d, are driven leftward. The conductor pairs may comprise end conductors separated from the main conductors by small insulating gaps. The drive motors are de-energized when the trolleys engage a pair of end conductors which are not connected to a voltage-source, and for the purpose of reversing polarities, each conductor pair and its end conductors are connected to a unit 4a-4d. The motors may be of the threephase type, closure of a master switch and momentary actuation of a push-button of any carriage energizing a relay to operate a drivemotor which is stopped after a predetermined period. An emergency switch may be operated by a pedal to open the master switch. In another embodiment, the motors are operated from two phase mains.

Abstract: 456,576. Linear dimension gauges. TURPIN, T. K., Finaghy Park North, Belfast. Feb. 11, 1935, No. 4290. [Class 106 (ii)] A measuring gauge has means including a plurality of balls or rollers contained in an arcuate track for converting motion in one direction' of a feeler into motion in a direction at an angle thereto of a member associated with indicating mechanism. Movement of a feeler 1 is transmitted through a number of balls or rollers 3, in a curved tube or groove 4, to a rod 8 loaded by a spring 16 and adapted to bear against a tappet 19 for actuating a pointer 37 moving over a dial 2 supported by a sleeve 18 mounted on a tube 14 secured to a block 11 containing the curved track. The block has a threaded aperture 20 to receive an abutment 21 which may be replaced by others of different length. By inserting the gauge in the part to be measured and adjusting the pointer to zero, the gauge may be used as a limit gauge. Accurate measurement of internal cylinder diameters is obtained by forming on the block 11 bored lateral extensions 30, Fig. 2, in each of which a rod 31 slides. A spring 32 on each rod bears against a plate 33 provided with a pair of arcuate knife edges 34, concentric with the axis of the feeler, movement of the plate being limited by collars 35 riveted to the rear ends of the rods. When the gauge is inserted in a cylinder A, the abutment 21 and the knife edges have three-point contact with the wall, and the axis of feeler and abutment will lie in a plane containing the cylinder axis, so that the measurement of no other chord than a diameter is ensured. Rocking of the gauge about the feeler axis does not affect the location of the feeler and abutment in an axial plane of the cylinder. The block 11 may be made in halves and the curved groove lined with white metal. In a modification, the single abutment 21 may be replaced by a pair of fixed abutments symmetrically space relative to, and in a line normal to and intersected by the axis of the feeler.
