Title: Method of stowing discrete material in mine workings
IPC: E21F15/08
Filed: 1974-05-24
Abstract: 1446128 Mining; concrete structures P H COOPER 24 May 1974 [28 May 1973 20 July 1973 6 Feb 1974 6 March 1974] 23454/74 Headings E1F and E1W [Also in Division B8] A method of stowing discrete material in mine workings consists in electing in situ an open frame, locating against the frame a filter medium that is composed of fabric of adequate strength, elasticity and resistance to tearing and having interstices of sufficient dimension to allow of free passage of water while retaining substantially all of the solid constituents of a grout, which is delivered into the filter, as the watery constituents percolate outwards through the filter to leave the solid constituents to set or compact within the filter. Preferably the grout is a cementious grout. The fabric may be woven polyalkylene, e.g. polypropylene, sisal, nylon, or a woven mixture of such polyalkylene and natural fibres, or a coarse base material sprayed with latex to reduce the pore size of the material so that the material has a light passing area of between 40 and 80%, preferably 63%. The fabric can be in sheet or tubular form, but is preferably in the form of a bag. The bag may be of composite form with a foot 20 of substantially water impervious material and at least the lower portion 18 of the sides formed of the pervious fabric. The configuration of the bag may be that of a substantially rectangular shape or it may taper from top to bottom, and it may have a closed top 22 with an inlet in the side walls near the top thereof.

Title: Improvements in the production of readily-trickling, fine-particled polyvinyl chloride containing plasticizer
IPC: C08J3/12
Filed: 1958-07-22
Abstract: Particles of polyvinyl chloride containing a softener are obtained by subjecting an aqueous suspension or emulsion containing P.V.C. and a softener to spray drying at 110 DEG -180 DEG C. and are subsequently rendered free-flowing by treatment with a current of a hot gas, e.g. air, at 140 to 200 DEG C.  Softeners specified are dioctyl and dibutyl phthalate, higher esters of adipic and sebacic acids and tricresyl phosphate.  Suitable emulsifiers, when used, are alkylsulphonates and alkali metal salts of alkysulphuric acid esters. In examples (i) 20% and (ii) 40% of dioctyl phthalate (by weight of the solids) is stirred with an emulsion of 48% P.V.C. and 2,5% sodium alkylsulphonate and the mixture spray dried at 140 DEG C.  The product is further dried in a current of hot air at 170 DEG C.

Title: Improvements in apparatus for measuring the difference between two fluid pressures
IPC: G01B13/02
Filed: 1959-07-08
Abstract: 890,970. Linear dimension gauges; pressure gauges. PRECISION MECANIQUE LABINAL. July 8, 1959 [July 16, 1958], No. 23509/59. Class 106 (2). A differential pressure gauge has a pair of deformable and connected diaphragms 9, 10 mounted in a narrow housing 28, and an optical system including a mirror 20 moved in accordance with movement of the diaphragms and arranged to deflect a light beam projecting a luminous spot on to a screen. In a pneumatic gauging unit in which air is supplied to two gauge heads 3, 5, the back pressures set up behind the heads 3, 5 are conducted to chambers 6, 7 separated by the double diaphragm unit 9, 10. Movement of this unit turns a lever 15 and thus a shaft 14. Pivotal movement of the shaft 14, which lies in the space between the diaphragms, acts on a mirror 20, hinged to rotate about a shaft perpendicular to the plane of the diaphragm unit, and thus deflects a light beam, the resulting movements of which are read from a scale extending parallel to the shaft 14. Thus the apparatus is kept within a narrow space and several such indicators may be set up alongside one another.

Title: Internal combustion engine piston
IPC: F02F3/10
Filed: 1962-06-19
Abstract: 962,036. Casting composite articles. H. MAHLE, and E. MAHLE, [trading as MAHLE KOMM.-GES.]. June 19, 1962 [June 19, 1961], No. 23525/62. Heading B3F. [Also in Division F2] An I.C. engine piston comprises a forged light-metal head 1, Figs. 1 and 2, formed integrally with pin bosses 3 and bearing, only in the region of the pin bosses, against the inner face of a separately produced light-metal skirt 4, the material of the head having a greater coefficient of thermal expansion than that of the skirt. The head 1 may be made of an Al-Cu alloy and the skirt, which may be of Al-Si alloy may be cast or forged. When made by casting the associated head is employed as the core together with two removable core members to provide clearances 5. The pin bosses are supported relatively to one another by ribs 6. In practice, the diameter of the skirt in the direction of the pin axis is made smaller than that of the engine cylinder. In operation, the head 1, which expands to the greater extent on heating, presses against the skirt 4 in the boss zone so that the skirt is ovalized due to the provision of the clearances 5 whereby its diameter increases in the direction of the pin axis and is reduced perpendicular thereto. In Fig. 3, a cast skirt 4 is connected to the piston head by headed or differential screws 7, 7<SP>1</SP>. Expansion-inhibiting steel plates 8 are cast integrally with the skirt and curve on heating due to their lower thermal expansion coefficient thus improving the contraction of the skirt. Alternatively, the steel plates may be replaced by a dove-tail shaped ring inserted in the inner surface of the skirt or by cast-in wire rings or by steel rings shrunk into the skirt.

Abstract: 891,224. Filing papers. COPELANDCHATTERSON CO. Ltd., and MANN, O. May 20, 1958 [July 25, 1957], No. 23565/57. Class 146(1) A loose leaf binding unit comprises two retaining bars which contact the covers of the book to which the unit is to be applied and each of the retaining bars has at least one projecting pin, one of which pins passes through aligned holes in the sheets to be filed when assembled and the other of which telescopically engages the first pin, a locking screw or bolt being provided which is mounted in the side of one of the pins so as to engage the other pin and lock the two retaining bars in position when screwed home and allow the bars to be drawn apart when loosened. As shown the bar 2 carries tubular pins 4a, 4b, 4c which pass through perforations in the sheets. Pins 3a, 3b, 3c on the bar 1 are inserted in the bores of the pins 4a, 4b, 4c so that the sheets are secured between the bars 1, 2 and distance pins 10, 11 on the bar 1 pass through further holes in the sheets to engage the bar 2. The parts are locked in this position by a screw 5 in the wall of the pin 4b which is tightened so as to grip the threaded or otherwise roughened surface of the pin 3b. A sleeve 6 encloses the pin 4b and has a slot 7 which engages an unthreaded portion of the screw 5 and prevents the screw from being screwed completely out of the pin. The centre holes of the sheets to be filed are slotted out to the edges of the sheets so as to allow access to the screw 5.

Abstract: 298,978. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalÚmit). Oct. 18, 1927, [Convention date]. Controlling flow of lubricant.-The supply of oil to a member is controlled by subjecting the flow, near the member, to a resistance by causing the oil to flow through a long capillary tube d, Fig. 1, arranged within a pipe c which is connected to a lubricator plug a by means of a screwed sleeve g which wedges a biconical ring f into conical seats in the plug and sleeve, the tube d being secured to a plug e closing the end of the pipe. According to the Specification as open to inspection under Sect. 91 (3) (a) the supply of oil may be controlled by arranging in the plug a an annular-grooved member h, Fig. 2 (Cancelled), of which the diameter is slightly less than the bore of the plug a, the member being held in position between the end of the pipe c and a shoulder i at the lower end of the plug a. This subject-matter does not appear in the Specification as accepted.
