Title: Improvements in or relating to covered sliding clasp fasteners
IPC: A44B19/40
Filed: 1955-03-04
Abstract: 783,453. Sliding clasp fasteners. RYSER, E., and VOUMARD, B. March 4, 1955 [March 6, 1954; March 6, 1954], No. 6452/55. Class 44 A method of manufacturing a sliding clasp fastener comprises casting each fastening element directly on to an edge of a supporting strip so that its clasp portion covers a smaller width of the strip than is covered on the opposite side, and defirming the portion of the fastening element on the latter side towards the central longitudinal plane of the fastener so that the strip extends as far as that plane and thus covers that side of the clasp portion which, would otherwise be visible when the fastener is closed. The clasp portion of the element is defined as that part of the element which engages with the elements on the opposite strip. As shown, each element 12 is cast in a threepart mould 24. 26, 28, on to the beaded edge 22 of a supporting strip 10, the casting material being fed through a passage 29 to form two arms 30, 32 of the element, the arm 30 being formed with a projection. 37 and complementary depression 38 by which the elements are interengaged one with the other. A nose 34 on the arm 32 is deformed to clamp the element on to the strip 10. In other arrangements Figs. 5-12 (not shown), the nose 34 may be defined by a notch and the arm 32, or the arms may be plain and the clamping action obtained by a swaging operation, or the arm 32 may be flush with, or extend laterally of the arm 30. Also, the bead' portion 22 may be of a shape other than that shown on Figs. 2-4 and may be disposed symmetrically to or asymmetrically to a plane parallel to the supporting strips and passing through the centre of the arm 30. The elements may made of metal or synthetic plastic. In a further arrangement Figs. 12 to 15 (not shown), the strip is perforated, whereby the two arms of each element are joined through the strip.

Title: Continuous filter rod making machines
IPC: A01D46/247
Filed: 1972-02-11
Abstract: 1424664 Cigarette filter rod: crimping and condensing filaments MOLINS LTD 9 April 1973 [7 Jan 1972 11 Feb 1972] 891/72 and 6614/72 Heading D1F A filter for a continuous cigarette filter rod is formed by feeding a band of filaments onto a suction surface which is moving at a slower rate so that the filaments are crimped, and then narrowing the band to form the filler while retaining the crimp in the filaments. The filter material may be cellulose acetate. In a first embodiment an upper run of a perforate conveyor moves from left to right, Fig. 1 and has a cover 12 whose upstream edge is turned over to form, Fig. 2, a part-conical deflecting tunnel 13. A suction chamber beneath the conveyor has end wall 16 extending parallel to the tunnel. Filaments are fed into the conveyor at a faster speed than the conveyor so that they are crimped, and are conveyed until rotated clockwise within the tunnel by tunnel wall 14, while moving in the tunnel diagonally of the conveyor. Air from duct 15 assists the filament rolling. Alternatively, a continuous suction conveyor has a lower run moving in a direction F, Fig. 1, to narrow the filament barrel. The lower run 120A, Fig. 4, is carried in member 121 oscillated on spindle 122 and containing suction chamber 123. In a second embodiment, Fig. 5, two perforate suction drums 210, 213 rotate at the same peripheral speed about suction-blanking members 212, 215. Suction through the drums draws crimped filaments from between walls 218, 219 at a speed greater than that of the drums to further crimp the filaments. Drum 210 carries away the filaments which are plasticised with liquid and heated to set the crimps, and are transferred to suction drum 220. Before, during or after transfer, the filament band is narrowed by converging baffles 221. In a modification (Fig. 6, not shown) the converging baffles guide the filament band from rectangular to circular crosssection between the second and third rollers, the circular band being carried in a semicircular suction groove in the periphery of the third drum. To reset the filaments in their circular form during their passage around the third drum, solvent or plasticiser may be applied, or the filaments may be reheated. For Figures see next column

Patent GB-765972-A (GB)
Title: Improvements in or relating to aldehyde hydrogenation
IPC: C07C29/141
Filed: 1954-03-09
Abstract: Aldehydes are hydrogenated to alcohols by a continuous process in which the aldehydes are heated to hydrogenation temperatures in a heating zone and then passed to a catalytic hydrogenation zone for conversion to alcohols at elevated temperature and pressure, there being maintained an extraneous cooling fluid at a pressure above and a temperature below those obtaining in the hydrogenation zone and means provided for the admission of this fluid to the aldehyde-comprising stream passing from the heating zone to the hydrogenation zone when the temperature of this stream reaches a predetermined maximum safe value, the fluid being admitted in amounts sufficient to decrease the temperature of the flowing stream to below this safe maximum, the fluid being hydrogen or an inert fluid, e.g. water.  The maximum safe temperature is that above which temperature runaway takes place in the hydrogenation zone such as occurs when the aldehyde feed is overheated in the heating zone.  The process is described with particular reference to the hydrogenation of oxo aldehydes using a hydrogenator comprising a plurality of hydrogenation zones interspersed with cooling zones, the catalyst being a molybdenum, nickel, copper chromite or other hydrogenation catalyst but preferably molybdenum sulphide on activated carbon.  The aldehydes, with small amounts of water to prevent secondary reaction, are fed to a heating zone from which the issuing stream at 400-550 DEG  F. passes with hydrogen into the hydrogenator.  The hydrogenation products are then cooled to about 120 DEG  F. and the liquefied alcohols separated from unchanged hydrogen.  This unchanged hydrogen is continuously circulated with make-up hydrogen in a closed system containing a compressor whereby the circulating gas is maintained at a pressure above that in the hydrogenation zone which is normally about 2500-4500 p.s.i.g.  Part of this hydrogen is fed with the aldehyde into the heating zone, some is added to the heated stream from this zone and another portion is fed to the cooling zones of the hydrogenator for normal control of the reaction.  The bulk, however, is available for introduction into the effluent stream leaving the heating zone whenever the effluent temperature reaches about 600 DEG  F., this admission being affected automatically by a temperature recording controller automatically operating appropriate valves.  In an alternative embodiment there is provided, in place of the circulating body of cooled hydrogen, a supply of water at about 60-100 DEG  F., maintained under a high pressure, e.g. 3500 p.s.i.g., the admission of the water being likewise automatically controlled. Specifications 664,974 and 671,608 are referred to.

Title: Improvements in or relating to radio transceivers
IPC: H01J17/04
Filed: 1952-03-17
Abstract: 703,894. Waveguides. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 17, 1952 [March 20, 1951], No. 6833/52. Class 40 (8). [Also in Group XL(c)] A radio transceiving device for carrier wave pulses comprises transmitting and receiving waveguides 3, 5 directionally coupled by slots 9 in a common wall so as to decouple the transmitter 2 from the receiver 7, and gas and/or vapour switch cells 11 at the slots completing the decoupling by blocking the slots and receiver waveguide each time a pulse is transmitted to a common transmitting and receiving aerial 4. By this arrangement voltage spikes are prevented from reaching the receiver at the commencement of a transmitted pulse due to the finite time for ionization of the switch cells, and may be directed to another aerial or absorbed by a wedge-shaped plate 12 of resistance material at the end of the receiver waveguide remote from the receiver. Further the coupling factor may be unity so that waves reflected at 12 are almost entirely retransferred back to the waveguide 3. The directional coupling may be formed by a transverse slot in the common wall and by a longitudinal slot near one end of the transverse slot, so that the coupling is little dependent on frequency variations about the mean frequency. In a modification gas-tight windows of insulating material are placed across the receiver waveguide at both sides of the coupling slots and the latter filled by insulating gas seals to form a chamber containing gas or other ionizing medium, across the slot seals of which a glow discharge spreads on a transmitted pulse. The waveguides may alternatively connect at an angle. A mechanical rotary switch may replace the gas cells. The arrangement may be applied to radar or duplex pulse communication systems.

Class 111 A scraper carried for a sedimentation or like tank is of buoyant tubular construction, is adapted to be secured rigidly at its ends to endless chains or other flexible scraper-traversing means, and has a scraper blade attached to one side of it. Such a carrier may comprise a closed metal tube d, Fig. 3, secured between chains a which are located one at each side of a tank b, Fig. 1. A rubber or like scraper blade e or a longitudinal series of blades may be balanced by a mass f on the opposite side to obviate torque on the chains when the carrier is traversing the vertical part of the path. Alternatively, the points of attachment to the chains may be so disposed that the carrier itself counterbalances the weight of the scraper. The diameter and mass of the carrier are chosen so that the weight is counterbalanced by the upward thrust of the liquid. The horizontal portions of the chain are supported on skids c, Fig 1, or rollers. The scraper when moving along the floor of the tank sweeps the deposits thereon into a collecting trough g and when moving along the surface of the liquid in the tank sweeps the floating matter into a duct h at the other end of the tank.

Abstract: 525,949. Diaphragm pumps. BIGNELL, J. C. March 3, 1939, Nos. 7071 and 12308. [Class 102 (i)] [Also in Group XXIX] A diaphragm pump particularly for introducing liquids, e.g., calcium hypochlorite, into elevated tanks, or systems containing liquid under pressure, comprises suction and delivery valves, each housed in a sleeve which is applied to the pump-casing and is closed at the outer end by a cap-like member formed with a suction or delivery passage. In the pump shown in the Figure, a diaphragm 11, clamped between the casing 10a and a chamber 10b, is connected by a slide 18 and rod 17 to an eccentric on a shaft 14 driven by a motor 13. The pump-chamber 10b communicates with suction and delivery valves 29, 30, each consisting of a slotted sleeve 31 covered by a rubber sleeve 32 formed with slits 33. Each valve is surrounded by a glass or syntheticresin sleeve 24 which is seated in a recess 20 or 21 in the chamber and is retained by a cap or fitting 25 formed with an inlet 34 or outlet 38 and secured by a screw 27. Each sleeve 24 and a flange on the associated sleeve 31 abut on gaskets 26. The discharge-fitting 25 is provided with a diaphragm 36 which normally closes a passage 35. Ball or like valves may replace the above-described valves. The eccentric consists of an eccentric sleeve 41 which engages a strap on the rod 17 and is secured by a screw to an eccentric part 40 of the shaft. On slackening the screw, the sleeve 41 can be adjusted to vary the stroke of the diaphragm. A backing-plate 19 for the diaphragm conforms thereto at the end of the discharge-stroke.
