Title: Improvements in or relating to the manufacture of molded articles, and more particularly to articles such as artificial teeth
IPC: A61C13/08
Filed: 1946-05-24
Abstract: 612,477. Artificial teeth. DEHN, S. G. (Justi & Son, Inc., H. D.). May 24, 1946, No. 15854. [Class 81(ii)] [Also in Group V] Artificial teeth are moulded from thermoplastic material, e.g., methyl methacrylate polymer, by transferring the material from a central reservoir in a mould part into radial mould cavities 14 by means of centrifugal force. The cavities are first filled with translucent material 17 to form the incisal tip and part of the labial surface, then with a contrasting material 20 and if desired with further material 21 which contrasts with both the materials 17 and 20. The shape taken up by the material 17 in the cavities may be varied by varying the speed of rotation of the mould. The change in colour between each material may be abrupt of gradual.

Each watt-hour (or water or gas) meter 20 includes a resonant circuit 56, 58 of a respective resonant frequency. A unit 32 in the repeater unit 14 applies the resonant frequencies in turn to conductor 72 via an amplifier 34. If a unit of the utility is consumed at 50, a relay contact 60 is closed and when the resonant frequency of the particular meter arrives the low impedance at 56, 58, 60 causes an increase in power consumption at the amplifier 34 which is detected at 36 (by an amplifier, rectifier and thresholder) to apply a count pulse to a counter in 16 respective to the meter. Conductors 30 and 72 are provided within an insulating covering which insulates them from each other and the outside, the insulator surrounding one conductor being connected by a narrow neck to the insulator surrounding the other. Conductor 72 may be provided in the form of a group of parallel strands within its portion of the insulating covering. Other repeater units with respective groups of meters may also be provided, e.g. with the insulating coverings surrounding their stranded conductors 72 being linked, by necks to that surrounding the same conductor 30. A central station may interrogate the repeater units to read out the counts to it. As a modification, A.C. signals can be supplied by the meters to conductor 72, conductor 30 being used as a return conductor.

Abstract: 1,181,235. Valves. E. F. J. WOODS, [trading as AMOTS & CO.]. 7 July, 1967 [13 April, 1966], No. 16099/66. Heading F2V. A butterfly valve comprises a body 11 defining a valve seat 25 and a valve disc 27 tiltable out of the plane of the seat to permit rotation of the disc to open the valve, the disc being carried on a spindle 41 mounted at one end in a pintle bearing or ball-and-socket joint 33 to permit both rotation and pivoting of the spindle and at the other end in a bearing which permits only rotation but is itself movable. A bush 43 non- rotatably mounted on the valve spindle 41 has a pair of oppositely-projecting lobes 47, 45 to co-operate with an opening cam 51 and a closing cam 49 driven from a spindle 55 by a bush 63 which has a spur member 91 to engage a notch 93 in an end portion 95 of the spindle to rotate the latter when it is in the tilted position. The bush and cams may be provided with interengaging projections to provide driving engagement or they may be made in one piece with a drive-shaft 55. During anticlockwise rotation, the cam 51 tilts the spindle 41 away from the seat and is provided with a portion which is clear of the lobe 47 during rotation of the valve and spindle through 90 degrees, the valve being held at a constant angle of tilt by engagement of the lobe 85 with a portion of constant radius on the closing cam 49. During reverse rotation, the latter first restores the spindle to its upright position and then exerts a wedging action during the final portion of its travel. The valve may be operated by a hand wheel or by pneumatic, hydraulic or electrical means and a spigot 97 on the bush 43 may act as an end stop.

Title: Method and apparatus for the manufacture of asbestos-cement tubes

Filed: 1930-05-27
Abstract: 361,933. Moulding pipes and tubes from pulp. NICOLAJENKO, N. I. and KRAUSE, V. J., Potschtowoje Otd, Koliberevo, Moscow, U.S.S.R. May 27, 1930, No. 16332. [Class 87 (ii).] In manufacturing tubes from asbestos cement by a paste-board machine, the forming-roller is moved axially relatively to the pressure rollers so that the pulp is wound therein in overlapping conical layers in helical formation. The reduced ends of a series of forming rollers 6, Fig. 4, 9 and 11, are supported end-to-end on transverse supports 20 stretched between a pair of driven travelling chains. As each roller comes into the zone of the pressure-rollers 5, 7 it is engaged and rotated by the pulp-carrying belt driven by the roller 5, during which movement the pulp is transferred to it from the belt. On passing beyond this zone, the wound roller is removed, stripped, and re-inserted at the other end of the machine. By this means tubes longer than the length of the individual forming-rollers may be manufactured. The rollers 5, 7 are weighted at 12, 14 to press against the roller 6 and are carried in spherical or universally-jointed bearings 10 so that they can be adjusted both vertically and horizontally. In operation the rollers 5, 7 are slightly coned and are set at an acute angle to the axis of the roller 6, which angle varies in accordance with the diameter and thickness of the tubes to be produced. The rollers 5, 7 on opposite sides of the roller 6 will be inclined equally in opposite directions, and the run of the pulpcarrying belt will be at right-angles to the axis of the driving-roller 5. In a modified form sets of conical belt-carrying rollers 5, Figs. 14 and 16, are arranged in cages so as to rotate and also feed the core 6 forward bv friction. The core is introduced to the half-cages 32 and first full cage 33, Fig. 16 and thence is fed to the pulp-applying apparatus 25, being delivered finally to the cages 30 and half-cages 31. The non-pulp-applying cages may be driven at greater speeds than the pulp-applying ones at will to effect quick delivery and initial feed.

Abstract: 1390017 Mechanical switches without quick action JOSEPH LUCAS (INDUSTRIES) Ltd 17 May 1972 [21 May 1971 9 July 1971] 16390/71 and 32259/71 Heading H1N An electric switch is operated from a reel assembly of a vehicle safety harness through a reduction gear whereby contacts 17, 19, Fig. 2, engage after a required number of turns of the reel 9. In the example shown the reduction gear comprises a Geneva mechanism 11, 12 with the notched driving disc 12 coupled to the reel shaft 18 and a further pinion 13 engaging an inner toothed gear casing 14 carrying a bridging contact 17 co-operating with a pair of contacts 19 on a fixed housing 10. The gear casing 14 may be withdrawn axially against a compression spring 16 to disengage the gears 13, 14 during initial setting. In another embodiment a conductive ball contact (34), Fig. 4 (not shown), bridges a pair of fixed contacts (36, 37) mounted respectively on fixed and rotating casing parts (30, 31) whereby the ball moves radially in a groove (35) of the fixed part,(30) under the action of a scroll groove formed by a spiral spring (33) attached centrally to the rotary part (31) which permits overtravel due to the spring (33) having a free outer end. In other modifications the movable contact comprises a threaded nut or flanged disc 116, Fig. 8, movable axially along a threaded spindle 113 driven from the reel through a coupling 111, 112. The contact disc 116 is held against rotation by projections 115 on a sleeve 114 which is frictionally held against rotation in a fixed housing 110 but which can be rotated as by a tool engaged in a central slot 118 for initially setting the axial position of the disc 116.

The valves are constituted by plugs such as 24, Fig. 4, controlled by springs 44 actuated by handles 32 the channels for the fluid being formed in plates 27, 29 and a plate 28 being interposed between the handles and plate 27 and carrying the appropriate legends such as " on", " off ", " propeller brake " &c. Fluid flow takes place when the valves 22, 24 are disposed as in Fig. 3, flow being inhibited by valves 21, 23..In the case of a propeller brake where there are two extreme positions but no neutral position, a buildup of pressure when the extreme position is reached is avoided by using the valve 22, Fig. 5, in which the lower faces of ports 83, 84 are larger than the upper faces so that when pressure increases the valve body which is cylindrical, moves against the action of spring 44 until channel 116 connects the supply direct with the discharge channel.
