Abstract: 583,550. Relief valves. VENNING, J. D. E. Aug. 10, 1944, No. 15289. [Class 135]. In a gas venting valve for liquid pipe lines having an axial bore constricted to form a seat 6, Fig. 1, for a ball 7 or other valve member normally held off the seat by the extended end 10 of a spring 9, a piston 14 engaging the ball 7 is formed with grooves 15, 16 to allow the passage of escaping gas. When the liquid reaches the piston the grooves offer such resistance to flow that the piston overcomes the spring pressure and pushes the ball on to its seat thus closing the valve. In a modification, the spring acts on the ball through a non-return valve 24, Fig. 4, seating on the construction, and a hollow ported piston 25 is used.

Title: Improvements in and relating to continuous gauges
IPC: G01B5/04
Filed: 1937-06-07
Abstract: 479,656. Linear - dimension gauges. NILES - BEMENT - POND CO. June 7, 1937, No. 15703. Convention date, Aug. 1, 1936. [Class 106 (ii)] Relates to gauges of the kind described in Specification 445,812 in which the work is passed between gauging rolls mounted on a body member and on a relatively movable member, the relative movement being indicated by an indicator controlled by an armature actuated by a rod mounted on one of the relatively moving members, and in which a micrometer is provided for setting the gauge; and consists in arranging the micrometer spindle in axial alignment with the armature actuating rod. A body portion 10 is supported by parallel links 11 from a slide 12. A vertically disposed member 14 provided with friction rollers 15 slides in guideways in the body 10 and carries a gauging roller 17 whose axis is parallel to a similar gauging roller 16 carries in the frame the axis being at right-angles to the direction of movement of the strip w to be gauged. Both rollers have narrow workengaging surfaces. To counteract the weight of the slide 14 and to provide means for varying the pressure of one roll against the other, springs 19 are provided surrounding lugs on a member 18 adjustably clamped to the body 10 and bearing against opposite surfaces of the slide 14. Outstanding from the slide 14 is a projection 20 in which is disposed a slidable rod 21 normally pressed upward by a light spring 22 and clamped by means 23 engaging a thin sleeve 24 surrounding the rod. Engaging the rod 21 is the spindle 25 of a micrometer adjustment device secured by a nut 36 to the slide 14 the rod 21 forming in effect an extension of spindle 25. A gauge head 30 mounted upon a plate 31 secured to the body 10 houses a flexibly mounted armature 32 the free end of which lies between coils 33 and which is pressed upwards by a light spring 29. The coils 33 are connected to two solenoids 40 to form a potentiometer to which an E.M.F. is applied by a transformer connected to a source of alternating current. The instrument 34 is connected across the potentiometer through a plate rectifier 39. To adjust the gauge the rolls 16, 17 are placed in contact and clamp 23 released. The spindle 25 is now moved and the armature 32 is adjusted so that instrument 34 reads zero. The micrometer thimble 37 is then adjusted so that its zero aligns with the reference line of the body. Now it is merely necessary to release clamp 23 again and to adjust the micrometer to indicate the thickness of the sheet to be tested, when the instrument 34 will read zero when the material between the rollers is of correct thickness and variations will be shown right and left of zero.

Class 20(ii) In a telescopic pit prop, the inner member 2 which may be tapered, is clamped to the outer member 1 by means of a movable pressure jaw 4 and a pressure jaw 3 secured to or integral with the outer member 1, pressure being effected by toggle levers 6, 7 pivoted to the jaws 3, 4, the toggle joint 8 being supported for vertical adjustment by a cross wedge 9 carried on the outer member 1 and the joint 8 being carried in the lever arm 7 for displacement along that arm. The joint 8 is supported in a socket in a cross piece 10 between which and an inclined surface on the end portion 12 of the lever arm 7 is arranged a wedge H with its base supported on the cross wedge 9. When setting the prop, the wedge 9 is driven inwards, so that the wedge 11 is pressed upwards and the joint 8 thereby displaced sideways until resistance is reached by the jaws 3, 4 abutting the inner member whereupon further movement of the wedge 9 swings the toggle levers upwards to clamp the inner member 2. The jaws 3, 4 may have friction inserts of aluminium alloy.

[Also in Division D1] A pneumatic mechanism is provided associated with a circular knitting machine and operates by drawing a cast-off stocking into a cylindrical container 7 gripping the stocking at one end by a gripper 5 whereafter the air flow is reversed so that the stocking is held horizontally extended. The flow of air is then shut off and the bottom of the container opened as the gripper simultaneously releases the stocking to let it fall into a deep tray positioned beneath the container. A number of stockings produced on the machine are thereby laid out in the tray one piled on another. In the event of the gripper 5 failing to hold the stocking when the flow is reversed the loose stocking impinges on an electrical contact 6 which operates to stop the machine.

Title: Method for treating a permeable mass

IPC: C09K8/50
Filed: 1963-04-22
Abstract: A solution containing a polyepoxide having more than one epoxy group <FORM:0971855/C3/1> per molecule, a curing agent, a ketone and an aromatic hydrocarbon is injected into the pore space of a permeable mass and retained in the mass for a sufficient period to permit an intermediate resinous product to separate from the solution, deposit on the particles of the mass and cure to a hard cross-linked resin. The compound is obtained by reacting diphenylolpropane with an excess of epichlorohydrin in alkaline medium, has a molecular weight of 350-400 and contains an average of 1.85 epoxy groups per molecule. The curing agent is an amine such as bis(3-methyl -4- aminocyclohexyl)methane, the ketone acts as a reaction retarder and is preferably acetone, and the aromatic hydrocarbon used as or in the solvent is benzine or a benzine derivative, or is obtained by extraction of kerosene or other oils. To ensure total separation of the resin, phenol is added to the solution but when using curing agents other than bis(3-methyl-4-aminocyclohexyl) methane the phenol may be dispensed with. The total amount of compound and curing agent in the solution is 3-50 vol per cent. The injection process may be used to strengthen earth, the strengthening being accompanied by partial or total loss of permeability. Specification 971,854 is referred to.  Reference has been directed by the Comptroller to Specification 928,127.

Abstract: 687,787. Expanding pulley variable-speed gearing. ELLIOT, T. W. J., DRUCE, H. SKINNER-, and INDUSTRIAL DRIVES, Ltd. Feb. 21, 1951 [June 27, 1950], No. 15968/50. Class 80 (ii). An electric motor 1, Fig. 1, is mounted on a slide 4, Fig. 4, in an undercut groove of a guide 3 inclined to the axis of a base part 2, and is moved by rotation of a handwheel 7. The driving shaft of the motor carries an expanding pulley 8, 9 consisting of two telescoping barrels 11, 12, Fig. 7, the barrel 11 being keyed to the motor driving shaft 10, while the barrel 12 is keyed for rotation with the barrel 11 but is axially slidable thereon. A spindle 15, with a lubricating nipple 17, is mounted in a bearing 16 in the barrel 12, which can thus rotate round it. The spindle 15 is attached to a slide 21, Fig. 1, on a guide bar 18 adjustably. secured to the base 2 by supports 20, the axis b-b of the slide being parallel to the pulley faces. The path a-a traversed by the motor is similarly parallel to the pulley faces. As change of velocity ratio is produced, by transverse movement of the pulley and the corresponding increase or decrease in the separation of the pulley flanges 8, 9, the plane of the belt is kept constant. In a modification, Fig. 8 (not shown), the pulley has one inclined face and one plane face. A form of countershaft gearing is described, Fig. 9 (not shown), in which two pulleys according to the invention are mounted on a shaft rotatably secured to inclined guide means, similar to those 3, 4 of the motor, one half of each pulley also being connected to an inclined guide bar. The countershaft is used with two belts in series, the arrangement being such that as the distance between the faces of one pulley is decreased, the distance between the faces of the other is increased. The guide means may be curved, to correspond to the use of curved pulley flanges.
