Title: Improvements in and relating to pneumatic despatch apparatus
IPC: B65G51/16
Filed: 1937-11-27
Abstract: 493,484. Pneumatic despatch apparatus. DART CASH CARRIER CO., Ltd., EDWARDS, W. A., and MACHIN, F. Nov. 27, 1937, No. 32778. [Class 78 (i)] In pneumatic despatch apparatus of the closed tube type a main control valve is normally held closed on to its seating by the combined effect of gravity and the main suction pull in the tube line, but is caused to open by an auxiliary suction when a flap in the suction line is opened for the insertion of a carrier and thereby breaks the main suction pull, the opening of the valve being followed by the shutting off of the auxiliary suction communication which had opened it, whereupon the valve returns to closed position by gravity. The main control valve 18 in its lowest position closes the mouth of the air inlet tube 13 leading to the carrier tube 10. This valve is secured to a sleeve 19 which slides on a rod 20 depending from the top of a casing 23. 'A flexible diaphragm 24 attached to the sleeve and to the walls of the casing forms the bottom of a chamber 25 which is in communication with the suction line 29 by means of the passages 26, 28 and with the atmosphere through a passage 37. The passage 28 is provided with a rotatable valve 30 which is actuated by a paddle member 32 projecting into the tube 13 and also is controlled by balance weights 33. When a carrier is inserted in any part of the tube 10 by opening a flap, such as 15, the vacuum is broken and since the valve 18 is no longer subjected to suction, it is raised by the flexible diaphragm 24 and air enters the tube 13 through the opening 22. The air flow forces the paddle 32 downwards and the valve 30 is rotated to stop communication between the chamber 25 and the tube 29. Since the diaphragm 24 is no longer subjected to suction it descends, the valve 18 again closes the tube 13, and the balance weights 33 return the valve and paddle to the position shown. The rate of descent of the valve is controlled by the timing screw 36. A ball valve 27 drops on to its seating when the valve 30 is closed and prevents any suction effect in the chamber 25 due to leakage. The magnitude of the suction exerted on the diaphragm 24 is regulated by a set screw 34. Specification 433,000, [Group XVIII], is referred to.

Abstract: 342,683. Photographic surveying. SOC. ANON. DES USINES GALLUS, 77, Boulevard de la Mission Marchand, Courbevoie, Seine, France. Oct. 30, 1929, No. 32924. Convention date, Nov. 30, 1928. [Class 97 (ii).] In apparatus for use in preparing maps &c. from aerial photographs, in which two photographs of the same tract of country taken from different viewpoints are projected by adjustably mounted projectors on to a screen, the screen is marked with a series of parallel straight lines and the projectors are adjusted so that corresponding rays fall on the same line, thus avoiding the necessity for moving the screen vertically until the said rays intersect on the screen. In the apparatus shown the projectors 1, 2 are mounted so as to be rotatable about their optical axes in members 3 which are pivoted about axes Y, Y<1> in forks 4 which are pivoted about axes O, O<1> in members 5 slidably mounted on tubes 6, 7 rigidly connected together. The tube 6 is supported by a member 8 rotatably mounted in a sleeve 9 which is integral with a sleeve 10 slidably mounted on the member 11 which supports the projection screen E. A number of parallel lines a .. d are marked on the screen so that in using the apparatus it is only necessary to adjust the projectors until the traces m, n of corresponding rays fall on the same line of the series. Adjustment according to the scale of the map to be produced is effected by varying the distance between the projectors and the height of the sleeve 10 on the support 11. Instead of a series of lines, a single line may be used ; this may be marked on the screen which is then made movable in its own plane, or the line may be marked on a separate strip which can be traversed across the screen. For use in apparatus based on stereoscopic vision the apparatus is modified by displacing the projector 2 laterally with respect to the projector 1.

Abstract: A paper-machine felt is made by weaving a base structure of more than one layer so as to have both mutually united front and back layers therein of which the back layer is formed so as to contribute the major proportion of the tensile strength of the base of the front layer is composed wholly or mainly of wool and then needling the front layer into and on to the back layer.  The base structure may be a duplex fabric, i.e. two single woven plies bound together during weaving by binder yarns, or a semi-duplex fabric, i.e. a fabric which comprises either two layers of warp threads woven together with a common weft or two layers of weft threads weaving with a common warp. Preferably, the base structure is woven tubular with yarns of lower twist in the outer layer and yarns of harder twist in the inner layer and is transferred to a needling machine wherein the weft yarns become the circumferentially lengthwise yarns.  After needling, the felt is turned inside out and a further needling operation is carried out on the now outermost layer.  The yarns of the front layer are spun yarns containing at least 70% of wool fibres and at most 30% of synthetic fibres.  The yarns of the back layer may be composed wholly of wool or may be spun from a blend of wool and synthetic fibres or may be formed by twisting together a wool yarn and a continuous multi-filament synthetic yarn or may be formed by twisting a yarn spun from a blend of wool and synthetic fibres with a continuous multifiliament synthetic yarn or may be composed entirely of synthetic fibres or continuous synthetic multifilaments.
