Title: Valve block
IPC: F16K31/40
Filed: 1962-11-22
Abstract: 970,776. Valves. PARKER-HANNIFIN CORPORATION. Nov. 22, 1962 [Dec. 5, 1961], No. 44251/62. Heading F2V. A valve block has passages therein for flow of fluid therethrough and passages in which are mounted two valve elements 51 slidable axially to and from each other, each valve element including a plunger portion 50 on which fluid pressure is designed to act to move the element axially in one direction, and a valve head 54 spaced from the plunger portion, the valve block having axially spaced seats 47, 48 on each side of the head for alternate engagement by the head upon movement of the element in opposite directions. When the valve elements are in the positions shown, fluid from an inlet 9 flows through the right-hand seat 48 to a service port (not shown) while a second service port is connected through the left-hand seat 48 to an exhaust port 10. Energization of a solenoid 35 pulls an armature 38 on to a valve seat 40 to isolate a space 64 between the plungers 50 from a passage 27 and a check valve 26 leading to the inlet port 9 and to connect it through a seat 39, opened by the same movement of the armature, and through passages 70, 67, 68 and 69 with the exhaust port 10. Fluid pressure acting on the left hand side of the head 54 of the left hand element and on the right hand side of the plunger 50 of the right hand element now displaces the two elements axially towards each other to reverse the connections to the service ports. The passage 27 communicates with a reservoir (not shown) to permit continued operation in the event of failure of the supply to the port 9 while a cam 42 permits manual actuation of the armature. A plug 12 may be removed to enable remote pilot pressure to be used while plug elements 18, 29 are mounted for slight relative movement in separate parts 2, 3 of the block to accommodate misalignment of an electrical supply connection during assembly. A second connection between separate parts 3 and 4 of the block allows the solenoid to be detached. Fingers 47<SP>11</SP> on the seat 47 hold the seat 48 in place and a spring 53 between the valve elements may be replaced by C-shaped springs on the stems 56. In a modification, two solenoids are employed to control a pair of valves for connecting the space between the plungers to supply and exhaust. Specification 970,777 is referred to.

Title: Treatment of cellulosic fabrics
IPC: D06M11/11
Filed: 1962-11-27
Abstract: Cellulosic fabrics are crease proofed by impregnating then with an aqueous liquid containing an aldehyde, or a substance which is capable of liberating an aldehyde, in the absence of an acid catalyst, and then contacting them with gaseous hydrogen choride, sulphur trioxide or sulphur dioxide at a temperature below 50 DEG C. while maintaining the moisture content of the fabric at from 3 to 20% by weight.  Suitable aldehydes and aldehyde liberating substances which preferably applied to the fabric in an amount of from 1 to 25% by weight, are formaldehyde, glyoxol, glutaraldehyde, paraformaldehyde, acetal, methylol hydantoin and hexamethylene tetramine.  The aqueous liquid may also contain an aldehyde catcher, i.e. a substance capable of holding or retaining the aldehyde during the drying and acid treatment, e.g. polyethyl acrylate, polybutyl acrylate, polyethyl butyl acrylate, polyhydroxy ethyl acrylate, methyl cellulose, ethyl cellulose and hydroxy ethyl cellulose, blueing agents, brightening agents and softeners, e.g. polyethylene, polypropylene and silicon type softeners.  After treatment with the aqueous liquid the fabric may be dried at a temperature between room temperature and 120 DEG C. to reduce its moisture content to 3-20% by weight and then treated with an atmosphere containing 1-100% by volume of gaseous hydrogen chloride, sulphur trioxide or sulphur dioxide.  The fabric may be contacted with the gaseous acid substance by introduced or by contacting it with a continuously travelling porous belt, e.g. polystyrene sponge sheet, impregnated with hydrochloric acid so that the fabric is contacted with the hydrogen chloride gas developed.  The fabric may be contacted with the gaseous acid substance for a few seconds up to 90 minutes and then washed. Alternatively after treatment with the gaseous acid substance the fabric may be left to stand in an acid-free atmosphere at a temperature below 50 DEG C. until the reaction is complete and then washed.  The gaseous acid may be mixed with air, nitrogen or moisture.  Woven, knitted or non-woven fabrics comprising cotton, linen, hemp, viscose rayon or cuprammonium rayon fibres alone or in admixture with cellulose acetate, polyamide, polyester, polyacrylonitrile, polyolefin, polyvinyl chloride, polyvinylidine chloride or polyvinyl alcohol fibres may be treated.  The fabric may be mercerized of alkylated with dimethyl sulphate, diethyl sulphate, butyl chloride, ethyl chloride, butyl bromide, ethyl bromide, ethylene chlorohydrin, ethylenebromohydrin, chloracetic acid, bromoacetic acid or ethylene or propylene oxide in an aqueous medium or in an alcohol or benzene in the presence of an alkali prior, to the treatment.  Example 3 refers to the treatment of viscose rayon staple fibres graft copolymerized with ethyl acrylate.

Filed: 1969-09-11
Abstract: 1,254,613. Bowling pin detection apparatus. BRUNSWICK CORP. 11 Sept., 1969 [23 Sept., 1968], No. 44935/69. Heading A6D. In bowling pin handling apparatus, pin detection apparatus comprises a normally operative primary detection means to detect standing pins, and a normally inoperative auxiliary detection means to detect fallen pins when a pin is standing out of range of the primary detection means. Standing pins are normally detected after a ball by means of switches positioned behind resilient pads in the apertures in the deck structure when this is lowered to engage the heads of the standing pins. If, however, a standing pin has been moved to a position out of range of one of the apertures and engages the deck structure or one of the lateral extensions thereof (45, Fig. 3), this is prevented from lowering, making detection by the primary means impossible, and a switch (110) is actuated to actuate the auxiliary detection means. The auxiliary detection means comprises a counter switch 95 connected into an electronic counting circuit and actuated by an arm 96 engaged by one end of a trip lever arm 75 having at its other end a roller 77 which is displaced, thereby pivoting arm 75, by a pin passing between the walls 65, 66 of a cross conveyor 19 along which the fallen pins are transported. After deadwood has been removed, a switch is manually operated which, after a predetermined time delay disables the auxiliary detection means and restores normal operation of the handling apparatus.
