Title: Improvements in or relating to Epicyclic Gearing and method of Gear Changing
IPC: F16H3/66
Filed: 1967-01-20
Abstract: 1,169,920. Planetary change-speed gearing. TATRA NARODNI PODNIK. 20 Jan., 1967 [21 Jan., 1966], No. 3146/67. Heading F2D. In a change-speed gear having two planetary trains in series to give four forward and two reverse ratios, the first train planet carrier 4 is rigid with the second stage sun pinion 13 and may be connected by a friction clutch 30 to the second train planet carrier 17 which is rigid with an output shaft 27. In a motor vehicle, a gear input shaft 1 is connectible to an engine crank-shaft 25 by a friction main clutch 23. The first train comprises planets 5 meshing a reaction sun 6, a reaction annulus gear 7, and stepped planets 3 which in turn mesh an input sun pinion on the shaft 1. A brake 28 holds the sun 6 for first train reduced drive, a clutch 10 couples the sun 6 and the carrier 4 for first train direct drive, and a brake 26 holds the annulus 7 for reverse. The second train comprises a sun 13, planets 14, and an annulus gear 15. A brake 29 holds the annulus 15 for second train reduced drive, and the clutch 30 couples the sun 13 and planet carriers 4, 17 together for second train direct drive. The four forward ratios are obtained using the following first and second train ratio combinations: reduced-reduced, direct-reduced, reduced-direct and direct-direct. The reverse ratios are obtained using reverse-reduced and reverse-direct. All clutches and brakes are friction disc types, and all are disengaged for Neutral. As shown, with the main clutch 23 and the gear-box on opposite sides of a driven axle (not shown) the input and output shafts 1, 27 extend coaxially from the same end of the gear-box, the shaft 27 driving a final drive bevel 22 via pinions 19, 20. Alternatively the shafts 1, 27 may extend from opposite ends of the box (Fig. 2, not shown).

Title: Improvements in or relating to dehydrogenation catalysts and method of preparing same
IPC: B01J27/232
Filed: 1945-06-19
Abstract: A dehydrogenation catalyst is prepared by calcining a superficial layer of granules of a naturally-occurring carbonate of calcium or magnesium to a stage in which decarbonation of the granules to a state of oxide takes place only to a minor proportion of their weight and discontinuing the calcination at a stage in which the granules are still in a state containing an uncarbonated inner carbonate core constituting the major proportion by weight of the catalyst and of substantially the same carbonate composition as that of the original granules.  The carbonate treated may be limestone, dolomite, dolomite limestone, ferruginous limestone, or magnesite.  The calcination is preferably effected at temperatures of 600-650 DEG  C.  The calcination may either be effected in a pre-calcination step or in situ in the dehydrogenation reactor by flowing preheated steam, organic vapours to be dehydrogenated, or mixtures thereof, over the granules.

Title: Line voltage regulator apparatus in x-ray systems
IPC: G05F1/52
Filed: 1968-01-22
Abstract: 1,149,709. Automatic voltage control. WESTINGHOUSE ELECTRIC CORP. Jan.22, 1968 [Feb.16, 1967], No.3190/68. Heading G3R. [Also in Divisions H1 and H2] In an automatic A. C. voltage regulator of the type including a transformer with a tap selector switch having a pair of jointly movable contacts which normally engage a single stationary tapping- contact on a winding of the transformer and which momentarily bridge adjacent contacts when jointly moved from one contact to another, there is provided an interlock arrangement which ensures that the movable contacts do not stop in the bridging position when a tap change is effected. As shown, a load such as an X-ray tube X is supplied from an A. C. source by way of an auto-transformer T1, a transformer T4 and a rectifier R; the primary winding of the auto-transformer T1 has tappings connected to stationary contacts 32, 33, 34 co-operable with a pair of jointly movable contacts 30 which are inter-connected by a choke coil Xl and which are driven by a reversible motor MD1. A regulating circuit RM, including a voltage divider R1-R11, a reference tube V3, thyratrons V1, V2 and relays Kl, K2, controls the motor MD1 in dependence upon fluctuations in the secondary voltage of the auto-transformer so that the contacts 30 are moved in one direction or the other in a sense to restore the secondary voltage to a predetermined value. The choke coil Xl has a centre tap connected to one side of the A. C. supply source so that the ampere-turns of the two winding halves will cancel each other when the contacts 30 are on the same stationary contact; when a tap-changing movement is effected by the motor MD1 under control of the regulator RM, however, the contacts 30 will momentarily bridge adjacent stationary contacts. In this position, the winding halves of the choke coil Xl carry unequal currents and a signal is produced in a detector winding DW electromagnetically coupled to the coil Xl ; this signal is applied to modify the action of the regulator RM to ensure that the motor MD1 will not stop while the movable contacts are in the bridging position, thus providing protection from burn-outs of the auto-transformer winding during operation of the tap selector switch. When the load is an X-ray tube as shown, it is desirable to prevent operation of the tap selector switch while an X-ray exposure is being taken, and to prevent the taking of an X-ray exposure while the tap selector switch is being operated; the relays K3 and Kt are inter-connected, as shown, with the relays K1 K2 for this interlocking function.

Title: Improvements in or relating to the production of printing plates
IPC: C23C16/455
Filed: 1956-02-01
Abstract: 786,245. Printing surfaces. COMMONWEALTH ENGINEERING CO. OF OHIO. Feb. 1, 1956, No. 3221/56. Class 100(2) A method of producing a printing plate comprises the steps of heating a mould surface to at least 200F. and contacting the heated surface of the mould with a metal compound e.g. a vapour containing a nickel carbonyl whereby the vapour is decomposed depositing metal over the mould surface. The metal film is subsequently backed with a strengthening material such as lead and the upper face of the plate may be provided with a thin layer of chromium. As shown carbon dioxide gas is fed from a tank 1 through a line 4 to a carburetter 5 where a nickel bearing compound is vaporized. The tank 7 containing the carburetter 5 is filled with oil which is kept at a constant temperature by a thermostat device 10. The nickel-bearing vapour is passed to a pump 20 where it is pumped into a chamber 22 on which there is secured a metal plate 24 insulated from the walls by members 25. The vapour is pumped along a conduit 26 and issues from apertures 28 where nickel is deposited on a mould 27. The chamber 22 is surrounded by a water jacket 30 adjacent which is an inductive heating coil 36. One end of the chamber is provided with a removable cover 38 for the insertion of moulds. The cover is provided with a conduit 40 leading to a trap 42 surrounded by cooling water. The nickel still being carried by the carbon dioxide is deposited in the trap 42 while the carbon dioxide passes out to the atmosphere. The mould, which may be of papiermache, plastic, or lead is kept at a temperature of 200-280F., the carburetter temperature being in the range 50-75F. The plating gas preferably consists of nickel carbonyl and a carbon dioxide carrier. In an example a papier mache mould was maintained at 280F., and the carburetter at 70F. The rate of flow of carrier gas was 20 litres per minute and the rate of deposition 0.0015 inch per minute. This gave a nickel coating of 0.005 inch in a mould of 4 inches by 4 inches in approximately 3 minutes.

Title: Automatic Monitoring System
IPC: G01N33/00
Filed: 1968-01-22
Abstract: 1,187,541. Sampling radiation. ATELIERS DE MONTAGE ELECTRIQUES. Jan.22, 1968 [Jan.20, 1967], No.3226/68. Heading G1A. In a sampling system both the duration of individual sampling operations and the interval between samplings are discretely altered as the level of successive samples transgresses a threshold value. An apparatus for measuring radioactive particle content of air by deposition on a filter paper is described. As shown a pump 13 is periodically operated say for four minutes once every hour and draws air through a portion 14a of the filter paper. After each period the paper is advanced by a motor 16 so that the exposed portion moves to a detecting zone 14b adjacent a Geiger counter 17. The pulses produced by the Geiger counter are amplified at 19 and after regneration by a monostable circuit 20 are applied to a gate 21 which is opened at the appropriate time for a period determined by a timer 41. The pulses passed by the gate are applied to a divider circuit 22 which passes every pulse, every other pulse or every fourth pulse (according to its setting as described below) to a counter 24 and to a printer 23. The counter 24, a threshold valve storage circuit 27 and a comparator 28 together constitute a counter which gives an output pulse on a line S 1  when the count passes a first threshold, an output pulse on a line S 2  when the count passes a second threshold and an output on a line a to an alarm device 29 when the count passes an alarm threshold. The pulses on the lines S 1  and S 2  are counted on a counter (not shown) within a circuit 25. The counter which comprises a pair of bistables is re-set once during each period and controls latching relays which determine the scaling factor to be used by the divider 22 during the next test period. The relays also control a speed reducer 262 through which a cam shaft 263, functioning to produce timing signals for the various operations, is driven. Thus for example as the level of radioactivity detected increases the sampling periods change from four minutes once every hour to two minutes once every half hour then to one minute every quarter hour. The precise moment at which a danger level is reached can thus be determined accurately while economising on power that may be supplied from a battery.

Abstract: 434,518. Furnace floors. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.-(Assignees of Shellenberger, R. ; 203, North Chestnut Street, Westfield, New Jersey, U.S.A.) Feb. 1, 1935, No. 3359. Convention date, Feb. 2, 1934. [Class 51 (i)] In a furnace adapted to retain at the bottom a pool 68 of molten slag, the furnace floor comprises metallic blocks 50 secured to spaced cooling tubes 16 and means positioned externally of the blocks and co-operating with the tubes to form narrow slag solidifying passages communicating with the joints between the floor blocks. The blocks are preferably of rectangular form and are secured to water tubes 16 by means of clamps 52 which bridge the joints between adjacent blocks and which are formed with side portions 54 having recesses to engage the undersides of the tubes. The clamps are spaced from the undersides of the blocks to form passages 58 into which the slag flows from the spaces 56 between the blocks and in which the slag solidifies, thus preventing leakage from the molten pool. Flow of slag may be further retarded by heat resisting material forced into recesses 60 at the ends of the clamps and by plastic refractory material forced into the spaces between the blocks. The molten slag is drawn off through a tap hole 70. The tubes 16 are connected at their discharge ends with a header 36 communicating with a steam and water drum 22 through tubes 38 and 42 and their inlet ends with a header 46 communicating with the drum 22 through tubes 44. The walls are formed by rows of tubes 12 and 14.

Abstract: 646,353. Radiolocation; pulse modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 9, 1945, No. 3367. Convention date, Oct. 26, 1943. [Classes 40 (v) and 40 (vii)] In a system for determining the speed or drift of an aircraft relative to the ground utilizing the Doppler effect, pulses of radio frequency energy are radiated towards the ground in two directions so that the carrier frequencies of the two sets of reflected signals are shifted by different amounts, the difference frequency being a measure of the required velocity. According to the invention the two sets of reflected signals are applied to a detector giving a pulse train amplitude modulated at the difference frequency which is fed to a circuit tuned to the pulse recurrence frequency to give a similarly modulated sine wave signal, the modulation frequency of which is extracted and applied to a frequency meter. As shown, the transmitter 12 controlled by the 15 kc/s. master oscillator 13 and pulse generator 14 radiates pulses in the forward and rearward directions from the aerials 10, 11 and the pulses reflected by the ground in these directions are received by the aerials 22, 21 and fed to two parallel receiver channels where they are heterodyned first by the common local oscillator 26 and then by the synchronized local oscillators 46, 47; the common oscillator 26 may comprise a tuned-grid tuned-anode oscillator with the grid and anode circuits coupled to separate mixers in the two receiver channels to avoid cross-coupling. Due to the Doppler effect, the wave frequencies of the pulses received in the forward and rearward directions are respectively increased and decreased and the I.Fs. of the two sets of pulses produced by the two channels differ in the same way. These two sets of pulses are combined in the amplifier 57 and applied to the detector 69 to give a 15 kc/s. pulse train 76 amplitude modulated at the difference frequency which is applied to a 15 kc/s. resonant circuit 59 of low Q to give a sinusoidal wave 78 also modulated at the difference frequency. The wave 78 is rectified by the diode 61 and integrated by the filter 83 to give a series of pulses 84 having a recurrence frequency equal to the difference frequency and these pulses are shaped by valve 86 and applied to a pulse counter 62 which indicates the difference frequency and hence the forward ground speed of the aircraft. Owing to the finite beam width of the directional transmission, reflection would take place from a considerable ground area and in order to limit this area the received signals are gated at a predetermined range by applying the output from the master oscillator 13 through a phase shifter 16 to the pulse generator 17 and shaper 20, the negative pulses 18 from which are applied as gating pulses to the cathode of the normally biassed-off detector 69. If required, the separate transmitting and receiving aerials could be replaced by common aerial systems.

Abstract: 877,715. Trueing grinding wheels. CINCINNATI MILLING MACHINE CO. Feb. 1, 1960 [June 25, 1959], No. 3441/60. Class 60. A method of thinning the workpiece-engaging periphery Z of a grinding wheel R comprises rotating the grinding wheel and moving forming tools 62, 63 towards the axis of the grinding wheel in straddling relation to the plane of the grinding wheel and in succession discrete movements, and, after each disorder movement, swinging the tools across opposite corners of the grinding wheel always in opposed relation. The forming tools, which may be diamonds, are carried on arms D, E secured to spindles 40, 41 having gears 53, 54 engaging idler gears 55, 56 on spindles 57, 58, the arrangment ensuring that rotation of the spindle 40 carrying the arm D in one direction results in rotation of the spindle 41 carrying the other arm E in the opposite direction. The spindles are mounted in bearings 42, 49 in a carriage 16 slidably adjustable on a support 15 by a screw-threaded spindle 25 which bears against a stop 27 on the support 15 and is provided with a knob 26. The device may be mounted in a vertical position above the grinding wheel and springs are provided on pin 28 secured to the support to partly counterbalance the weight of the carriage. In operation, the carriage is adjusted by the knob 26 to a position proximate the grinding wheel with the tools 62, 63 straddling the peripheral surface Z and is clamped in position by a screw 20. The spindles 40, 41 are rotated by a lever 65 to move the tools across the corners of the wheel, the tools moving together towards or away from the axis of the grinding wheel to balance the shearing forces acting on the wheel during the forming operation. A pin 49 cooperates with stops 66, 67 to limit the amount of rotation of the spindles. The carriage is then advanced a small distance and the process repeated until the periphery Z is of the desired width. At the end of the forming operation, the carriage is raised by the knob 26 to cause a trip member 68 to operate a switch 69 controlling the circuit of the machine so that the grinding operation may be recommenced.
