Abstract: 903,881. Coin-freed vending apparatus. CHARBONNAGES DE FRANCE. Oct. 3, 1960 [Feb. 24, 1960], No. 33862/60. Class 27. [Also in Group XXX] Coin-freed apparatus for dispensing articles, such as bags 3 of solid fuel, comprises vertical storage columns 1a 1b leading to a common shoot 6, an endless conveyer 32 for conveying the leading bag in the shoot up an inclined plane 8 into an outlet 35 and means for releasing doors 7a, 7b at the base of each column in succession so that the columns empty successively. Inserted coins 19 fall into a recess 10 in a slide 11 and hold a pawl 18 clear of a notch 11b so that it can be moved to operate a lever 15 and a switch 17 for energizing the conveyer motor 26. A full-stroke pawl 12 is provided and an air damper 21 ensures that the slide returns slowly enough to allow escape of the coins to a coin box. The motor rotates a gear 27 from which there are chain drives to rollers 29, 30 and the belt 32 is driven so that one of two or more members 33, 34 on the belt transfers the leading bag to the outlet 35 and then the gear 27 operates a switch to stop the motor. At each revolution of the gear 27, a cam 36 pivots a pawl-carrying plate 37 so that a rack bar 43 is displaced one step. The rack bar has a number of teeth corresponding to the total number of bags in the apparatus and rollers 44 are so spaced from latch levers for the doors 7a, 7b that, as each column empties, its latch is tilted and the door is allowed to open. When all the columns are emptied, the rack bar 43 operates a switch 49 which de-energizes the motor circuit and moves a blocking member behind the coin slot.

At low engine speed the magnet energizing current is maximum and the magnet 4 moves the valve element 12 right to connect the servo chamber 10 to a vacuum supply 16 for clutch disengagement. As engine speed increases and the magnet energizing current decreases, the valve element 12 moves left under the action of a spring 19 and the differential pressure across the valve element to close the vacuum supply duct 16 and slowly admit air to the chamber 10 through ducts 14, 20, 18. During ratio shift in a following change speed gear the magnet 4 is energized by closure of a gear shift lever actuated switch 31 for clutch disengagement. As shown movement of the clutch actuating servo piston 7 is transmitted to a clutch actuating lever 27 through a lever 40 and hydraulic linkage 41, 42. In Fig. 1 (not shown) the piston 7 is mechanically linked to the clutch actuating lever 27.

[Also in Group XXXIV] A fluid bearing has a rotatable member supported by fluid-pressure in an annular housing and means are provided for producing and maintaining said pressure, said means is effective by fluid supplied from a nozzle which extends around the cushion area. In an embodiment, a rotatable circular window 10 has outwardly-converging bearing surfaces 14, 15; two rings of turbine blades 16; and impulse buckets 17 on its periphery. The housing 11 has bearing surfaces 19, 20 and pressurized air is supplied to the clearances between the bearing surfaces 14, 19 and 15, 20, by means of inlets 28, 29 and passages 22, 23 and the air leaves through annular outlets 31, 32. In operation, the window 10 is rotated by nozzles 18 which direct air to the buckets 17 and by air from the outlets 32 which impinges on the blades 16. In a modification, the window has pressurized air directed on to one of its circular faces so as to balance the force caused by a relative movement between a craft, having said window fitted thereto, and the ambient air. The window is locked against rotation by an inflatable ring, heating elements are provided to overcome icing and a distributer for de-icing, or insect solvent, may be provided. The rotating of the window may be stopped by directing air to the buckets in an opposite direction to that of rotation. In an embodiment a shaft 120, Fig. 13, is supported in a housing and the axial length of the clearance therebetween is varied; the greatest length being at the lower part of the housing to compensate for the weight of the shaft &c. and the smallest length being at the upper part of the housing. A construction of a rig for testing bearings is described in the Specification. Specification 936,073 is referred to.

Title: Improvements in spinning viscose
IPC: C01B17/06

Abstract: Viscose fibres having a stable curliness are obtained by spinning a viscose according to the process described in the parent Specification, i.e. of salt point 0,1--0,2 or lower, and subjecting the fibres to vibrations and slight stretchings towards the end of, or shortly after coagulation.  The vibrations may be produced by using a spinning funnel whose exit is narrowed so that the parallel flow of the precipitating solution is changed to turbulent flow or by causing the fibres to enter water in which whirls are caused by the precipitating liquid entering with the fibres.  In the latter case a small quantity of acid or salt or both may be added to the water.

Title: Improvements in or relating to the continuous centrifugal casting of metals

Filed: 1957-11-08
Abstract: 827,262. Casting-processes. METALLURGIQUE D'ESPERANCE-LONGDOZ S.A: Nov. 8, 1957 [Nov. 9, 1956], No. 34914/57. Class 83 (1). In a method of continuous centrifugalcasting in a mould, or between two concentricmoulds 1, 2, a ring 5 of molten metal heavier than the casting-metal is interposed between the casting and the interior of the external mould 2. The heavy metal, which is particularly lead, silver, bismuth or alloys thereof, should not contaminate the cast-metal, e.g. steel, and must have a melting-point much lower than the cast-metal and a boiling-point, at the pressure created by the centrifuging, at least higher than the temperature existing in the mould at the contact with the solidified wall of the casting. The interior of the external mould may be finned, and in a further modification, Fig. 3, a member 8a reduces the heavy metal-ring to a thin lubricating film over the greater part of its length. The leakage may be collected by a trough, which may be of spiralform and connected to the mould, and returned to the supply. The system is self-regulating, in that a variation of the flow of heavy-metal will cause a variation in pressure in the ring, with consequent variation of casting diameter, which is then balanced by a variation of leakage-flow acting in the opposite direction on the pressure in the heavy-metal ring. The system can be controlled, manually or otherwise, by measuring the strain exerted by the external mould on its bearings and regulating the supply of heavy-metal to maintain this strain at an acceptable value. Specification 817,847 is referred to.
