Title: Improvements in or relating to apparatus for closing containers
Inventor: COOPER GRAHAM BABTIE
IPC: B65B31/04
Filed: 1963-07-24
Abstract: 1,005,947. Container closuring; packaging. METAL BOX CO. Ltd. May 29, 1964 [July 24, 1963], No. 29385/63. Headings B8C and B8T. A filled container, e.g. of powdered milk, has its gaseous content changed prior to the closuring thereof by gas-tightly covering its open end, withdrawing air therefrom while impeding the contents thereof against withdrawal, and restoring atmospheric pressure in the container by introducing an inert gas, e.g. hydrogen or nitrogen. As described this process immediately precedes the application of a cover to the container; the apparatus comprises a continuously rotatable spider 6 receiving filled containers 7, one at a time, from a conveyor, not shown. Each container is associated with a pad 10 having a filter 34, preventing the flow of container contents therefrom, and each pad is mounted on a hollow spindle 11 carried by an arm 12 extending from a pillar 13 rotatable with the spider. A cam roller 14 on each spindle engages a stationary cam 15 so that during rotation each pad is vertically reciprocated against spring action. Each spindle has a gas passage 32, 33 and slides in a stationary sleeve 28. The pillar includes a vacuum chamber 21 connected to a vacuum source, and a gas chamber 22 connected to an inert gas source; connections from chambers 21 and 22 lead to annular recesses 29, 30 in each sleeve 28. In operation the pad sealingly engages the container and the passage 32 is aligned with recess 29 causing the removal of air; continued spider rotation causes the spindle to rise to connect passage 32 to recess 30 thus permitting inert gas to be introduced. The container is then delivered to the sealer, not shown, which also has means for introducing an inert gas into the container headspace during the closuring operation.

Abstract: 1,080,463. Gear-cutting. DAVID BROWN GEAR INDUSTRIES Ltd. Oct. 18, 1965 [July 17, 1964], No. 29401/64. Heading B3K. A machine for producing globoidal worms and hobs comprises a support 18 rotatable about an axis 13, a tool spindle 22 rotatable about, and slidable along, an axis 29 intersecting the first axis and contained in a plane perpendicular thereto, and a work spindle 14 rotatable about a third axis parallel to, or contained in, said plane and tangential to a circle having its centre on the first axis. The support 18 is movable on guides 17 on a rotary table 12. The spindle mounting 19 is adjustable axially by rack-andpinion gearing and a hand wheel 21. The spindle is rotated by an electric motor (27) and belt gearing 25. In operation, the table 12 is rotated in unison with the work 30 so that the tool makes a sweeping traverse. The rotations are then quickly reversed to return the parts to their initial positions. The work is then indexed if there is to be more than one start or the tool is fed-in and a second cut taken. A finish-cut can be made with a grinding- wheel, the speed of rotation of the tool-spindle being increased. To ensure a true tooth-flank, finishing tools are of smaller diameter and are set so that the area of contact 14a, Fig. 4 (not shown), of the tool and one flank lies on the axis of the worm. Each flank is then finished separately.

Abstract: 1,081,780. Photo-electric exposure control. PENTAGON DRESDEN KAMERA-UND KINOWERKE VEB. July 14, 1965, No.29874/65. Heading G1A. Photographic printing apparatus includes a photo-multiplier, used to control the charging current to the exposure-timing capacitor, and having adjustable control elements, for the colour and density corrections and for linearizing the photo-multiplier output, which elements are connected to the cathode and to a number of the dynodes located near to the cathode, the remaining dynodes being at fixed potentials independent of the potential of the electrodes associated with the correction device. The latter dynodes 10-11 (Fig. 1) are supplied by constant voltage sources 13. A potentiometer 2, representing a number of elements correcting for colour and density, is supplied by source 1 and connected to the cathode 4 through potentiometer 3 and dynodes 7-10 via potentiometers 6, 9. The apparatus obviates the disadvantages of a system in which the photo-multiplier output is controlled by elements which alter all the electrode potentials simultaneously. In such a system the supply power has to be high and the linear range of the photo-multiplier is found to be sufficient. In the system of Fig. 1, the supply 1 for the control devices is of lower output since less dynodes are adjustably controlled thus reducing the degree of stabilization required. The linear range of the photo-multiplier can be extended by adjustment of the potentiometers 3, 6 and 9.

Title: Improvements in or relating to carrier current transmission systems
Inventor: CANNON JAMES ROWAN
IPC: H04B3/10
Filed: 1950-12-07
Abstract: 700,105. Automatic volume control. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 29, 1951 [Dec. 7, 1950], No. 29973/50. Class 40 (4). In a carrier current communication system, the gain in each direction is controlled by two pilot signals, one of which compersates equally over the whole range for a change of gain, and the other corrects for frequency-dependent changes of gain. A change in the level of either pilot exceeding a predetermined amount is prevented from operating the regulating means and the apparatus for effecting the correction for frequency-dependent changes is rendered inoperable whilst a change of flat gain is being made. Pilot currents transmitted one at each end of the band to be transmitted are applied to a gain control receiver GCR, Fig. 1, where they are separated, amplified and rectified to control through apparatus CEF and CES (shown in detail in Fig. 2) motors FCM and SCM which drive ganged capacitors in variable attenuators FCU and SCU. An increase in line attenuation reduces the current through relay SRA, Fig. 2, and closes contacts SBA1(L) which operate relays IG and F to prepare the circuit of motor FCM and operate a relay DS. The latter starts a timing circuit of the type described in Specification 614,472, [Group XL(c)], in which a valve V1 is made to strike and operate a relay PA after a condenser C1 normally biassing the grid of V1 negatively has discharged through resistors R4, R6 and R7 and recharged in the opposite direction. This can give the regulating equipment a delay in operating of up to 30 seconds. Relay PA energizes a relay SCF which locks up over contacts of relay F and releases the relay DS. The circuit of valve V1 reverts to normal and relay PA is released to complete the motor circuit. Contacts SRA1(L) open when sufficient adjustment has been made and the relays are all restored to normal. Should the flat-gain adjustment result in an excessive gain of the second pilot then contacts SRB1(H) close and motor SCM is operated through relay SCS to increase the attenuation at that end of the frequency band. Adjustment of the slopegain whilst the adjustment of flat-gain is in progress is prevented by relay F which opens the + ve feed to contacts SRB1. Relays SRC and SRD are operated if there is a rapid change of more than 4 db. and relays LAF and LAS are operated respectively to prevent the operation of the motors. Further contacts on these relays operate an alarm over' a lead 12 and light alarm lamps LPA, LPD. Overrun of the potentiometers is prevented by camoperated contacts FCC and SCC which open the motor circuits and provision is 'made for manual control over keys KC and KD. Specification 631,151, [Group XXXV], also is referred to.

Title: Improvements in and relating to catalyst manufacture
IPC: B01J23/00
Filed: 1957-09-25
Abstract: A catalyst is prepared by vaporizing aluminium chloride or bromide on to a previously prepared carrier consisting of a refractory oxide, such as silica, alumina, titanium dioxide, zirconium dioxide, chromia, zinc oxide or a naturally occurring form, and a metal selected from Groups VIa or VIII of Mendeleev's Periodic Classification of Elements; and heating the carrier to above 300 DEG C., preferably 400-600 DEG  C., to remove any unreacted aluminium halide.  The refractory oxide can be synthetically prepared gamma alumina and it can contain 0.01% to 8% combined halogen, preferably fluorine, and the metal, for example, Cr, Mo, W, Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pr, is composited with the refractory oxide by drying or precipitation or other known methods.  Platinum in the form of an ammoniacal solution of chloro platinic acid can be admixed with alumina and dried, or it can be precipitated by hydrogen sulphide from chloroplatinic acid and an alumina-gel slurry to give a concentration of 0.01% to 2%, by weight, of platinum.  Aluminium chloride or aluminium bromide is vaporized or sublimed on to the composite in the form of pellets or irregularly shaped particles. The vaporization can be carried out under pressure, or in the presence of diluents, such as inert gases including paraffin hydrocarbons, hydrogen and nitrogen, and a reaction is indicated by the evolution of hydrogen chloride.  Subsequent heating at above 300 DEG  C. results in either (a) the removal of the unreacted aluminium chloride, or (b) an additional reaction of the sublimed aluminium chloride as evidenced by the further evolution of hydrogen chloride. In the preferred embodiment whereby aluminium chloride is sublimed on to a platinum-alumina composite the temperature of composite during sublimation and the temperature of the composite during the subsequent heating, is the same.  For example, 112.1 grams of platinum-alumina composite in a vertical furnace at 600 DEG  C. was connected to 45 grams of heated anhydrous aluminium chloride for 3.5 hours until aluminium chloride vapour appeared at the top of the furnace.  The composite, after cooling, was found to have gained 6.7 grams in weight per hundred grams of composite.
