Title: Improvements relating to gramophones
IPC: G11B17/02
Filed: 1933-03-08
Abstract: 417,926. Gramophones. SCHULER, H. A. H., 1, Gartenstrasse, St. Georgen, Schwarzwald, Germany. March 8, 1933, No. 7026. [Class 40 (ii).] An automatic stopping mechanism for a gramophone comprises a part driven by the gramophone motor at the same angular speed as the tone-arm, relative movement between the tone-arm and the driven part causing the motor to be stopped. The tone arm 14 is adjustably secured to a spindle 8 on which are freely mounted a worm wheel 7 and a toothed wheel 23 adapted to be frictionally driven thereby through a spring 24, the wheel 7 being driven by a worm 6 on a flexible shaft 5 driven by the motor 2 in such manner that the angular speed of the wheel 7 is the same as that of the spindle 8 when the tone arm is traversing the spiral part of the record. An arm 26, fast on the spindle 8 carries a switch 25 which completes the motor circuit when a tooth on the switch engages between teeth on the wheel 23. At the end of the playing period relative movement occurs between the wheel 7 and the spindle 8, the wheel 23 thus being rotated to break the motor circuit. The turntable 4 may be braked, when the motor circuit is opened, by a spring- pressed plunger 40, Fig. 3, which is retracted, during playing by a solenoid in parallel with the motor. According to a modification, a low voltage relay may be employed to release a sear retaining the plunger in withdrawn position, the actuation of the sear causing the plunger to break the motor circuit and to apply the brake to the turntable. In a further modification, an arm 31<1>, Fig. 5, may be frictionally clamped to the wheel 7, the arm having a cam end 31 which engages with a projection 321 on a spindle 32 carrying the contact arm 25 of the switch. On relative motion occurring, at the end of the playing period, between the arm 311 and the member carrying the spindle 32, the projection 32<1> is actuated by the cam 31 to open the switch.

Title: A fluid pressure operated valve device
IPC: F16K31/40
Filed: 1949-03-16
Abstract: 672,696. Fluid-actuated valves. UNITED AIRCRAFT PRODUCTS, Inc. March 16, 1949, No. 7237/49. Class 135. A valve actuated by fluid pressure under the control of an electromagneticallyoperated auxiliary valve member has inlet and outlet ports 16, 19, respectively, Fig. 2, a main movable valve member 27 coacting with a seat 28 and integral with a piston 24 and a fluted guide 25, and an auxiliary valve member 35 coacting with a seat at the end of a passage 34 through the piston and valve member and urged, against a spring 36, towards closed position by an armature 37 upon energisation of a solenoid 42. The piston 24 permits leakage from the inlet ports to a chamber 32 whence fluid may escape through the passage 34 except when the auxiliary valve member is closed, when pressure developed in the chamber 32 opens the valve member 27 against a loading spring 29. In a modification, the auxiliary valve member seats on a fixed orificed plate at the end of the cylinder accommodating the piston and is spring-urged to the closed position, so that the main valve member is opened when the solenoid is de-energised. Also, instead of providing a leaky piston, an external conduit supplies fluid to the chamber behind the piston. Fig. 4 illustrates a further modification, also having a spring-closed auxiliary valve member 94 seating on a fixed plate 87, but in which the housing is formed to facilitate connection into a pipe line whereas the other constructions are intended for insertion into a pump casing. In Fig. 4, fluid from the inlet 79 passes through an orifice 91 into a chamber 92 connectable through a passage 103, with the outlet 81 under the control of the auxiliary valve member. Specification 493,169 is referred to.

Title: Improvements in filler bodies for carrying out reactions of gases with solids in fluidized beds
IPC: B01J19/30
Filed: 1955-03-15
Abstract: A reaction between a gas and a fine grained solid is carried out by passing the <PICT:0774325/III/1> gas through a fluidized bed of the solid containing hollow cylindrical filler bodies having portions cut out and projecting inwardly from the cylinder wall, e.g. as illustrated in Fig. 1. By means of said bodies the bulk density of the bed is increased and pressure fluctuations reduced; they may advantageously be allowed to remain stationary in the bed by selecting a suitable gas speed although vibratory motion is referred to.  Tables are given showing the increased bulk density of a fluidized bed incorporating said filler bodies.  The filler bodies may be made from metal, ceramic or synthetic materials and the process may be applied to adsorption or catalysis by the fine grained solid, to pyrites roasting or calcining calcium carbonate. Specification 630,155 and German Specification 853,159 are referred to.

Title: Improvements in Manufacture of Foam-Filled Sheet Products.
Inventor: MCCALLUM WILLIAM POTTER
IPC: D04H1/68
Filed: 1966-08-22
Abstract: 1,167,151. Non-woven fabrics; apparatus for impregnating webs; treating textiles. W. P. MCCULLUM. 22 Aug., 1966, No. 7701/66. Headings D1L, D1P and D1R. A reinforced foam-filled sheet product is made by compressing a compacted batting material of non-woven discontinuous fibres randomly oriented by forcing a foaming mixture in substantially inactive state into the batting and then expanding it in situ to space the fibres away from one another to a thickness greater than that of the compacted batting before compression, and curing the expanded foam. The batting may be of cotton, rayon or nylon fibres, preferably crimped and compacted by needling. The foam may be of polyurethane, and may have fine pores at the surface but coarser pores in the interior of the sheet. As shown, reactants forming the foam are supplied through lines 11 and 12 to a mixing head 10 which is oscillated across a carrier belt 15, of which the upper surface is coated with a release agent. Compacted batting material 25 lies on the belt, receives the mixture and is carried between the rolls 19 and 20, which compress it and force the mixture into it. A covering web 22 of paper coated with a release agent is also applied by the roll 19. The assembly then passes between steel plates 29 and 30. A manifold 31 supplies air to flexible hoses 32 and pipes 23 connected to recessed spaces or perforations in the inner surfaces of the plates, to provide air cushions between the plates, and the belt 15 and covering web 22. The bottom plate 30 is fixed, but the upper plate 29 floats vertically, but has a bag 39 fed with compressed air through a conduit 40 between it and a pressure plate 38. The pressure in the bag 39 is controlled to prevent too-rapid expansion of the foam. As the web emerges from between plates 29 and 30, foaming is substantially complete. The product is then passed through an oven 41, the covering web removed and wound up at 24, and the product carried again through the oven by a festoon conveyer and wound up at 43.
