Title: Method of manufacturing a pressurized fluid control valve
IPC: F16K11/044
Filed: 1969-12-01
Abstract: A reciprocating spool-type valve, particularly for controlling the supply and exhaust of pressure fluid to and from an actuator such as the jack 40, 42, comprises a valve body 22 having a chamber for the spool with longitudinally spaced inwardly projecting wall portions forming at least three annular valve seats such as the four seats 56, 60, 64, and 62, and a spool-like valve member having at least a pair of collars, such as the three collars 66, 68, 70, provided with corresponding closure surfaces for co-operation with the at least three seats, two of these closure surfaces 60, 64 being provided on one collar 68, such that one of these two closure surfaces along with a third closure surface such as 72 or 62, will seat simultaneously on the corresponding body seats. The valve may be controlled from the supply pressure of an air bottle 30 through a pilot valve 87 as shown. The valve may be pressure balanced by making the outer pair of closure surfaces of smaller diameter than the inner pair, Fig. 8 (not shown). In a double push-button valve, Fig. 4 (not shown), the inner pair of closure surfaces is made smaller so that the valve is held in each operated position by the fluid pressure. Similar effects can be achieved by recessing the inwardly projecting wall portions of the body, Fig. 13 (not shown). Methods of making.-Either the valve body or the spool, or both, may be moulded in a resiliently deformable plastics material such as polyurethane, neoprene, polyethylene, or rubber, and the spool is assembled by temporarily deforming one or other, or both, of the parts. Thus in Fig. 22, the plastic body 22 has been previously moulded in the material, using either a solid core which has been forcibly extracted or a destructible core otherwise removed. The spool is inserted, by bulging the body between plates 510, with an insertion tool 5081. The original body mould may be left on to form an outer casing (203), Fig. 6 (not shown). A spool 241, Fig. 23, pre-formed by the lost-wax process, has a lapping material 512 adhered to its closure surfaces by a substance 514 which can later be disintegrated and flushed away. Other details and variants.-A main spool and pilot spool valve arrangement may be formed in a one-piece body, Fig. 11 (not shown). The body can include an integral actuating lever with a roller (300, 302) or a solenoid (180) recessed into the body, Figs. 10 and 12 (not shown). Collar parts (105) only of the spool may be resilient, and grooves (157) may form flexible sealing lips carrying the closure faces, Figs. 8 and 18 (not shown). In a variant, the seats are flat and lands on the spool are grooved axially at (116). An adjustable flow restrictor in the exhaust passages is formed by a thin-walled portion of the body which is deformable by a ball (128) engaged by a screw (132), Figs. 15 and 16 (not shown).

Title: Improvements relating to devices for grinding scissors, knives and similar tools
IPC: B24B3/54
Filed: 1969-12-06
Abstract: In a device for grinding scissors, knives and similar tools, having a grinding wheel coupled to an electric motor and a guide member adapted to be located in a position relative to the grinding wheel in which at least one surface of the guide member forms a guide surface for one type of tool to be ground, the guide member is movable relative to the grinding wheel and is adjustable in different positions which each correspond to different supporting surfaces of of the guide member. A grinding wheel 4 is mounted on the shaft 3 of an electric motor 2 the wheel and motor are contained in a housing 1 having a base 6 and a reduced diameter portion 5 accommodating a motor-controlling switch 7. A cut-away portion 8 in the housing wall gives access to the grinding wheel. The housing has a stud 9 on which is rotatably mounted a circular guide member 10 having radial slots 11 symmetrically distributed round its circumference and bounded on either side by surfaces 12 for supporting the articles to be ground. The shapes, dimensions and slopes relative to the grinding wheel of the various supporting surfaces 12 are different and adapted to diverse kinds of tool, e.g. knives, scissors, chisels and screwdrivers which have different grinding angles. For grinding a tool, the guide member 10 is rotated so that the desired supporting surface 12 is directed to the grinding wheel 4 through the cut-away 8. Instead of using a separate guide member, a part of the housing may move relative to the remainder of the housing and be provided with supporting surfaces. The grinding wheel 4 may be external to the housing 1, the cut-away 8 being then dispensed with entirely or in part. The guide member may be in the form of an elongate strip 13 displaceable in the direction of its length to move the various supporting surfaces formed in it to a position above the grinding wheel. The guide member may be held in the different positions by a ball detent 14.

Title: A procedure with its corresponding device for the control of consistent effect yarns, with slacks twisted by a hollow spindle.
IPC: D01H/
Filed: 1977-08-12
Abstract: The invention relates to a procedure and its corresponding device for the control of consistent effect yarns, with slacks twisted by a hollow spindle.  The basis of the invention is to suspend the supply of the material when the base or fastening yarn, unwinding from the hollow spindle, is broken.  The issue is resolved by directly feeling the finished effect thread, the tension of which is altered by holding the slacks, formed by the yarn producing effect.  The slacks of the effect yarn are held by a small hook when the base or fastening yard is broken. This small hook is positioned in front of the yarn guide and immediately in front of this yarn guide is the contact tension measurer, the feeler arm of which exerts pressure on the finished yarn.

Title: Reciprocating piston beam engine
IPC: F02B75/24
Filed: 1978-05-11
Abstract: In the disclosed internal combustion engine opposing identical pairs of pistons drive back and forth arm ends of a centrally pivoted beam which is symmetrical about its pivot. Torque is extracted from the beam through an eccentric mechanism which is located between the end of one arm and the pivot. The other arm is provided with a symmetrically located second eccentric mechanism symmetrically spaced from the pivot and substantially identical with the first as regards the dynamic balancing, but not connected to the same output shaft as is the first eccenter mechanism. Also disclosed are combinations in which two or more such engines are connected together as units so that one or more of the units may be completely decoupled from the output shaft and thus inactivated. A special controllable coupling connecting the main shafts of such multiple units permits selective disengagement of the units and synchronized reengagement with predetermined relative angular orientation. Lubrication of the beam pivot is particularly effective when the beam is pivoted on the rotating output shaft of the engine, since that permits an effective lubricant film to be maintained.
