Title: Improvements in or relating to closures for containers
IPC: B65D47/26
Filed: 1967-06-06
Abstract: 1,165,418. Container closures. W. LEEDS and L. A. MICALLEF, [trading as LEED & MICALLEF]. 6 June, 1967 [16 June, 1966], No. 26153/67. Heading B8T. A dispensing closure comprises a cap 29 rotatably mounted on a container mouth 23, and a base 26 incorporating a plug 24. A spout 28 passes through the base 26 and can rotate therein about an axis B, offset from the central axis A of the cap. In the closed position, Fig. 1, the spout 28 is completely enclosed by the cap 29, but on rotation of the latter, a cam 37, Fig. 8, rotates the spout 28 in such a way that the end 33 emerges from the cap 29 through an aperture 34. A part (35), Fig. 3 (not shown), fixed to the base 26, closes the aperture 34 when the cap is in the closure position with the spout 28 retracted, and also provides stopping means (35a, 35b) for the rotation of the spout 28. In order to close the container, the cap 29 is rotated in the direction D, Fig. 8, when first the edge of the aperture 34, and later a further cam 38, cause the spout 28 to turn and retract into the closure position. The spout 28 may be provided with an air-vent 51, and also has a valve arrangement 41. In a modification, Figs. 9-11 (not shown), the axis B may be set at an angle to the axis A. In a further modification, Figs. 13- 15 (not shown), suitable for use with aerosol cans, a support (61) is provided so that the aerosol valve (58) cannot be depressed when the cap is in the closure position. In any of the embodiments, the aperture 34 may initially be closed by a frangible seal.

Title: Improvements in or relating to process of and apparatus for forming ceramic bodies
IPC: C04B35/14
Filed: 1939-09-20
Abstract: 532,781. Glass manufacture ; artificial stone. GARBISCH, N. S. Sept. 20, 1939, No. 26220. Convention date, Dec. 16, 1938. [Class 56] [Also in Group V] Waste sand from the grinding of plate glass is formed into tiles, bricks, and similar structural bodies by placing the material in a pan composed of relatively thin heat-resisting metal, placing the pan in a mould at a temperature above the sintering point of the glass contained in the material, and then subjecting the heated material to strong pressure to consolidate it into a coherent body. Glaze may be applied to the body while it is still hot. The pan 60, Fig. 7, preferably comprises flexible side walls 61 which are unconnected with one another, the dimensions of the pan being such that it fills the mould completely. The material in the pan is covered with a metal plate, and the filled pans are fed in succession through a tunnel kiln 63, Fig. 1, by a rod 65 provided with arms 66. The rod reciprocates and partly rotates, and the arms engage the pans and push them forwards As each pan leaves the kiln, it is received on the bottom plate 44; Fig. 4, of a mould 36 which is secured to the table 23 of a press 15. The table is raised and lowered by fluid-pressure cylinders 19 to move the mould to and from a plunger 58 which slides in a boss 52 secured to the press head 18. The mould bottom 44 is secured to a rod 43 which slides through the mould and is stopped, during its downward movement, by a screw 47, so that it does not descend below the level of the machine table 38. The mould is heated by the combustion of gases directed through channels 29 in the mould support. The plunger 58 is allowed to descend as the mould falls to reduce the flow of heat to the press head. After a pan of the heated material has been pressed, it is pushed off the mould bottom by a crosshead 80 operated by a cylinder 77, and passes over the table 38 and falls down a slope 82 on to a conveyer belt 83. During the fall, the pan engages a bar 81 and is inverted. The conveyer carries the pans between inclined endless belts 91, Fig. 1, which engage opposite sides of the pans and lift them off the pressed articles. The empty pans are deposited on a conveyer 99, while the articles are carried beneath the conveyer into a re-heating kiln 107. From this kiln, they are pushed into an annealing kiln 119 at the entrance to which powdered glaze is shaken on to them from a hopper 117. In a modification, the cover plates are removed from the pans by the application of suction through passages in the press plunger, and the glaze is applied while the pressed articles are still in the pans. Be-heating is unnecessary and the glazed articles pass directly into the annealing kiln.

Filed: 1971-04-19
Abstract: 1345177 X-ray apparatus M MOSS 19 April 1971 [27 April 1970] 26926/71 Heading H5R Apparatus suitable for taking panoramic, intra-oral occlusal and cephalometric radiographs of the head, jawbone, and teeth includes an X-ray source and a film holder coupled to one another for rotation about a patient positioned therebetween, and interchangeable means permitting movement, with respect to the patient, of the pivot point of the rotation. The radiographic apparatus is mounted on, and is vertically adjustable with respect to, an upright column 14 by means of a counterweighted support member 22, to which a hinged arm 26 supporting a head positioner 24 and an adjustable cassette holder 36 is also attached, the column 14 being itself horizontally adjustable along a base 12 by use of a control lever 41. The rotatable anode X-ray tube 16 and film holder 18 are mounted at opposite ends of a member 54 which also carries a motor 51 which, by driving a friction wheel 78 resting on a centrally apertured platform 50, can cause member 54 to rotate upon the platform. The member 54 has a pair of arms 58, 58<SP>1</SP>, the axis of rotation of member 54 being determined by the engagement of a cam follower pin or pins secured to a bracket 60 with apertures in a cam plate 52 mounted on platform 50 to extend over its central aperture. Both bracket 60 and plate 52 are readily detachable whereby, by use of differently pinned and apertured replacements, a desired axis of rotation may be achieved; further, by use of suitably shaped apertures in plate 52 (Fig. 5c, not shown), movement of the axis during rotation may be produced. For the taking of panoramic radiographs of a patient's head, the X-ray tube is locked in a position facing the film holder, which latter is additionally rotated about its axis in synchronism with the rotation of member 54. A changing axis of rotation may be produced either by use of a suitable cam plate 52, in which case the patient's head is secured in a central head positioner 98, or by operation of lever 41. For intra-oral radiography, nut 132 is loosened to permit the X-ray tube to rotate about its axis 134, a collimator 130 is coupled to the tube, and the film is positioned within the patient's mouth. For cephalometric radiography, the patient's head is held in the head positioner 24 and the film in cassette holder 36, towards which the collimated X-ray beam is directed. Hinge 27 in arm 26 enables positioner 24 and holder 36 to be swung out of the way, to permit X-raying of the chest.
