Title: Improvements in or relating to diazotype developing machines
Inventor: LONGDON WALTER
IPC: G03D5/06
Filed: 1959-10-13
Abstract: 890,530. Photographic developing apparatus. HALDEN & CO. Ltd., J. Sept. 13, 1960 [Oct. 13, 1959], No. 34595/59. Class 98(2). Developer liquid is applied to an exposed photographic paper 16 by a transfer roller 12 which is in peripheral contact with a liquid supply roller 10, the two rollers rotating in the same direction; the roller 12 also rotates in the same direction as the moving paper 16, but at a considerably-greater peripheral speed. Thus a narrow meniscus of liquid accumulates between the paper and roller 12 just where the two converge. Accordingly, the paper is subjected to a sufficient quantity of liquid to ensure proper development, but only a small quantity of liquid passes with the paper over roller 12, because the higher speed of the latter smooths off the liquid, so that the paper leaves the machine as dry as possible. The paper passes further between a take-off roller 19 and -an absorbent roller 17. The relative speed of the roller 12 both to the paper 16 and to the roller 10 can be varied.

Abstract: 429,694. Jib cranes; grab-buckets. MEYER, J. F., 700, Flintridge Avenue, Pasadena, California, U.S.A. Dec. 8, 1933, No. 34640. [Class 78 (iv)] [See also Groups XVIII and XV] A coin-freed vending-machine of the kind in which a jib 15, Figs. 1, 2, carrying a grab bucket 40, is moved laterally by rotating a hand wheel 85 to position the grab over a selected part of the platform 5 on which articles are arranged, is characterized by the provision of a collar 100 for limiting the vertical movement of the beam in varying degrees in different directions. The upper edge of the collar is so shaped that the end of the jib may lie over the front corners of the platform 5 but not outside its side and front edges. The grab comprises claws 39 connected by links 38 to a ring 37, the inner ends 41 of the claws being connected to a closing ring 42. After the insertion of a coin, levers 47, 48, 53 to which cables 34, 35, 50 are attached are so controlled by cams 57, 58, 59 driven by a motor 60 that the jib 15 and cables 34, 35 are lowered to place the grab upon a desired area on the platform, the grab closed and raised, the jib lifted to position the grab over the shoot 8 and the cable 34 lowered to release the article. The forward position of the jib may be adjusted by a lever 95 provided with a pin 94 for engagement with a rack 93 on the lever 50, the lever 95 being controlled through a friction clutch 106 by the hand wheel 85. A pin 107 on the pivot 24 of the jib engages lugs 108, 109 on the inside of the collar 100 to prevent the jib striking the rear wall of the machine. A spring 110 assists the jib outwardly during its initial movement from the vertical. Closure plates 121, 124, Fig. 5, prevent fraudulent extraction of articles from the shoot 8, the plate 121 normally being closed and the plate 124 open, the initial opening movement of the plate 121 automatically closing the plate 124.

Title: Power transmitting coupling
IPC: F01P7/04
Filed: 1963-09-04
Abstract: 994,954. Hydrodynamic couplings. EATON MANUFACTURING CO. Sept. 4, 1963 [Sept. 17, 1962], No. 35017/63. Heading F2C. A shear-type fluid coupling for driving a fan is generally similar to that described in Specification 898,442, having a plate 80 separating a reservoir 82 from an operating chamber having a driving member 42 co-operating with an adjacent wall of a driven body member 62, but flow of fluid between the reservoir and the operating chamber is controlled by means which is either responsive solely to the temperature of the coupling fluid, or is responsive to the temperature of the coupling fluid and to the ambient temperature. As shown, a helical bi-metallic element 102 is mounted on the exterior of a cover-plate 78 and serves to rotate a valve arm 108 from a position completely closing a port 110 to positions in which the port is partly or fully open. A bi-metallic strip 112 is welded at one end to the plate 80 and its other end overlies the valve arm 108 and partially obstructs the port 110, this end being closely adjacent the port 110 when the fluid is cold and moving axially away from the plate 80 to increase the effective opening of the port as the fluid temperature rises. The port 110 permits flow of fluid from the reservoir to the operating chamber, flow from the operating chamber to the reservoir being effected through a port 118 which is disposed ahead of pumping means comprising a projection 116 on the plate 80 which is disposed in an annular recess 56 formed on the driving element 44. In a modification the valve arm 108 and the exterior bimetallic element are dispensed with, in another modification the bi-metallic strip 112 cooperates with the port 118, the valve arm 108 either being dispensed with or co-operating with the port 110.

Title: Improvements in or relating to multichannel pulse communication systems
IPC: H04J3/18
Filed: 1947-12-31
Abstract: 656,151. Pulse multiplex signalling. STANDARD TELEPHONES & CABLES, Ltd. Dec. 31, 1947, No. 35125. Convention date, Aug. 6, 1943. [Class 40 (v)] Before transmission, the normal interlaced channel pulses of a multiplex pulse train are rearranged into successive groups each comprising a plurality of pulses all belonging to the same channel but to a different channel from those of adjacent groups. In one embodiment the six channel signal sources S1 ... S6, Fig. 2, are connected to the target electrodes 1 ... 6 respectively of a cathode-ray distributer O to produce a train of interlaced amplitude-modulated channel pulses at terminals C1, C2. These pulses are stored on the screen of an iconoscope tube II, in columns A1 ... A6 to A<SP>1</SP>1 ... A<SP>1</SP>6, Fig. 3, in a time T and then scanned horizontally in a further time T to produce the rearranged pulse groups. While the transcription is taking place, the next series of input pulses is being stored on a second iconoscope tube, or a double-beam tube may be used. One of the channels may be modulated with a characteristic signal to serve as a synchronizing channel. At the receiver, Fig. 5 (not shown), the incoming signals are stored on an iconoscope tube and transcribed to produce the normal interlaced train which is fed to a cathode-ray distributer feeding the individual channel circuits. In another receiver embodiment, the groups of received channel signals are separated by the cathode-ray distributer O, Fig. 6, and each group recorded magnetically at high speed on a steel wire U by a recording-head T1. The reproducing head T2 is arranged to produce output pulses at the normal rate, the relative speeds of the wire U and heads T1, T2, being suitably adjusted. A plurality of systems may be connected on a time-sharing basis to the same coaxial line circuit, Fig. 7 (not shown).

Abstract: 1,220,546. Travelling - wave tubes. THOMSON - CSF. 11 July, 1969 [12 July, 1968], No. 35173/69. Heading H1D. In a crossed-field travelling-wave tube, a grid 11 is disposed in front of, and close to, the surface of the cathode 1, which is itself mounted parallel to, and in face-to-face relationship with, the initial portion of the delay line 3 (of which only two portions are shown), whereby an auxiliary accelerating electrode plate opposite the cathode may be dispenesed with, with a consequent reduction of noise on the beam. As shown, a second cathode-grid assembly 11, 11<SP>1</SP> may be employed, at a distance downstream along the sole electrode 2 sufficient to ensure that the beam from the first cathode has moved sufficiently close to the delay line to reduce its space charge effect upon emission from the second cathode. In a modified arrangement (Fig. 3, not shown) the cathode surface and grid. are raised above the level of the sole electrode. The grid is held from one to several hundred volts negative with respect to the cathode. The tube, which may be of cylindrical rather than linear geometry, includes a screening electrode 8, and the meander delay line 3 is mounted on an insulator 5.

Title: Process for recovering platinum group metal from composites containing same and alumina
IPC: B01J23/96
Filed: 1957-11-12
Abstract: During the treatment of spent alumina platinum group metal catalysts to recover the metal values contained therein, solutions of aluminium salts such as the sulphate and chloride are formed by heating the spent catalyst to 121-204 DEG  C. at a pressure of 1.14 to 18 atmospheres with a concentrated acid such as sulphuric or hydrochloric acid.  In an example quoted, the catalyst was heated with 95% sulphuric acid for 4 hours at 149 DEG  C. in a sealed vessel. At the completion of the digestion, a polyacrylamide which has been 10-50% hydrolysed, by sodium hydroxide for example, is added to coagulate the noble metal, in an amount of 0.001-5% by weight of the aluminium salt present.  The noble metal is allowed to settle for 1 hour and the solution of the aluminium salt is removed by decantation.  Specification 755,487 is referred to.ALSO:Platinum group metals are recovered from spent catalysts consisting of a mixture of the metal and alumina, by digesting the mixture with acid to dissolve the alumina and adding a partially hydrolysed polyacrylamide to coagulate the platinum which is then separated from the solution of the aluminium salt. The spent catalyst is first heated in a oxidizing atmosphere to remove carbonaceous matter and is then heated to 121 DEG C-204 DEG C at a pressure of 1.14 to 18 atmospheres with concentrated acid e.g. sulphuric or hydrochloric acid.  In an example quoted, the time for digestion was 4 hours at 149 DEG C, using 95% sulphuric acid in a sealed vessel.  When treating a platinum-containing catalyst, a quantity of aluminium particles at least equal to the theoretical quantity required to precipitate any soluble platinum as metal may be added during the later stages of the digestion.  At the completion of the digestion, a polyacrylamide which has been 10-50% hydrolysed, by sodium hydroxide for example, is then added to coagulate the noble metal, in an amount of 0.001%-5% by weight of the aluminium salt present.  The noble metal is allowed to settle for 1 hour, the supernatant liquid decanted and the noble metal recovered.  Specification 755,487 is referred to.

Abstract: 1,021,665. Packaging-machines. J. G. H. OLLIER, G. F. GROSSHANS, and R. G. MASSON. Sept. 14, 1962, No. 35208/62. Heading B8C. [Also in Division B6] In a machine of the kind in which a succession of cups or pockets is formed in a web, the cups filled and a second web applied to close the cups to produce sealed packages, means is provided to ensure correct registration of printing &c. on the second web with the cups. The means comprises a device scanning registration marks on the second web, these marks being at a different spacing from the cups, and altering the position of the second web relative to the cups as necessary for correct registration. The invention is illustrated as applied to the machine as shown in Figs. 1 and 2 of Specification 866,314. The second web 2 is fed from a roll 4 to cover vacuum formed cups la, passing round a tensioning roller 40 and roller 4c to beneath heat sealing means securing it to the cups. In one embodiment a transparent web 2 is scanned by photo-electric means 34, 36 responding to opaque registration marks which are arranged at a spacing which is a function of that of the printed labelling 2b, the latter being spaced at intervals less than those of the cups. The combined webs are fed forward a distance equal to the cup spacing, but towards the end of this movement a signal from the means 34, 35 detecting a mark causes a roller 32 to descend and clamp the web 2 so that it is stretched to produce the correct registration on the cup about to be sealed. In a second embodiment (not shown) the labels are again at the lesser spacing and a device for producing a line of perforations extending transversely across the strip is provided to the right of roller 4c as viewed in Fig. 3. In this case a further forward movement of the combined webs after the clamping of roller 32 causes the strip 2 to tear just behind the cup about to be closed. The sealing jaws are wide enough to extend across the gap so formed so that the web 2 both forward and rearward of the tear is welded to strip 1. A web of metallic foil may be used. In a third embodiment suitable for use with metallic foil, the label spacing is arranged to be greater than that of the cups and the roller 32 is fitted with a ridge 32b (Fig. 5, not shown) which presses against the strip to form a transverse crease or deformation and reduce the effective spacing of the labels to an amount less than that of the cups. After the rollers have been clamped, further forward movement of the strip 2 causes extension of the web 2 by reduction in the size of the deformation. The photo-electric cell in this embodiment can be placed on the same side of the strip as the source of light in order to receive reflected light. Alternatively, the detectable means may be apertures in the strip.
