Patent GB-740358-A (GB)
Title: Improvements in or relating to electron discharge device for microwaves
Inventor: SVENSSON REGNAR HOLMFRID
IPC: H01J25/24
Filed: 1952-05-13
Abstract: 740,358. Velocity-modulated tubes. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 13, 1952, No. 12140/52. Class 39 (1). The cavity resonator 24 of a reflex tube is directly secured to a metal disc 35 sealed through the tube envelope for connection to an external waveguide 39, energy being transferred by a rectangular iris aperture 30, has a flexible wall 11 for tuning and an opposite wall having an inwardly projecting tube 27 serving as a focusing electrode and the end of which has a stepped portion 37 for capturing returning electrons after their passage through the resonator grids 36. The resonator 24 is soldered to disc 34 at 32 to give a good electrical and thermal contact; the disc can thus facilitate cooling of the resonator. The coupling of the resonator to the guide can be varied by rotating the tube about its axis. Insulating plates 25, 33 carry the gun 28, 29 and reflector 6 respectively. The gun comprises concave indirectlyheated cathode 28 and focusing electrode 29. A conical cap 4 with two diametrically opposed lugs 5 is attached to diaphragm 11 and the lugs 5 forming a yoke are attached to one end of support 12. Tube 14 containing heater 15 is attached by a lug at its upper end to support 12, and 14 and 12 are both secured at their lower ends to member 13 of a second yoke which supports the resonator via two yoke members 23. On energizing heater 15, tube 14 expands and support 12 pivots about its lower end, so decreasing the resonator gap spacing and reducing the oscillation frequency and also moving the reflector 6 by an equal distance. The frequency may be varied by varying the heater current of 15, e.g. by a magnetic amplifier. To tune the frequency automatically up and down within the tuning range, two contact springs 21, 22 are provided which are also actuated directly or indirectly by the thermal tuning member 14, 15 to switch on or off circuits controlling the extreme deformation positions of flexible wall 11. To increase the speed of tuning the maximum possible increase in length of 14 is made greater than that theoretically required for a given tuning range. To prevent excessive bending and consequent fracture of flexible wall 11, stopping devices may be used. The stopping devices may also prevent movement of the flexible diaphragm until the temperature of heater 15 is greater than say 250‹ C. The invention can also be applied to other discharge tubes with resonators enclosed within the envelope.

Title: Improvements in or relating to colouring treatment of anodic coatings on aluminium and its alloys
IPC: C25D11/24
Filed: 1936-04-29
Abstract: 474,609. Electrolytic surface treatment of aluminium and its alloys. ELECTRO - METALLURGICAL RESEARCH CO., Ltd., (in Liquidation), WERNICK, S., and HENLEY, V. F. F. April 29, 1936, No. 12236. [Class 41] [Also in Group XV] Anodically produced oxide coatings on aluminium or its alloys are subjected to the action of hot aqueous dye liquor of an organic mordant dyestuff which contains no metal in complex combination (other than a metallic radical when the dye is in the form of its salt, e.g. sodium salt) and in the absence of any reagent capable of reacting with the dyestuff to form such a complex combination; after the coating is fully tinted the treatment in the dye-bath is continued at a temperature of at least 180‹ F., and preferably at boiling point for a further period adequate to seal the pores of the coating. The dyes known under the Registered Trade Marks "Solway" "Solochrome " and "Chlorazol" are suitable. The anodic coating may be produced in a bath containing 20 per cent by volume of sulphuric acid at 75‹ F. with a voltage 11-12. Dyeing is effected after washing and without intermediate drying. The dye-bath may contain a small amount of acetic acid to assist penetration and a small amount of substance such as potassium dichromate which improves the corrosion resistance of the product. The dyed articles may be dipped in a solution of nickel acetate, nickel sulphate, or copper sulphate to improve the light-fastness. Specification 423,467, [Group XV], is referred to.

Filed: 1918-07-27
Abstract: 128,444. Napier &. Son, D., and Draper, F. R. July 27, 1918. Drawings to Specification. Preventing escape of oil from crank and cam shaft casings.-In order to prevent the passage of lubricant into the combustion chamber of an internal-combustion engine on the suction stroke, the pressures existing during this stroke on the opposite sides of the piston and at the opposite ends of the valve guides are equalized, or their normal ratios are varied. For this purpose the crank-case and a chamber enclosing the valve guides are made air-tight and are connected to the induction pipe. A three-way cock is placed in the communicating pipe so that the vacuum in the crank-case and chamber may be varied or destroyed, and this cock may be connected to the engine throttle in such a way that the prsesureequalizing effect only takes place when the throttle is nearly closed.

Title: Improvements in or relating to signalling apparatus for railways
IPC: B61L3/04
Filed: 1929-04-20
Abstract: 326,072. Price, N. J. April 20, 1929. T r a c k apparatus actuating signals on trains.-The driver of a locomotive is given warning and the brakes are partially applied whenever the train approaches a signal, whether the signal is in its " line clear " or its " danger " position. The locomotive carries a valve casing 1 with two chambers 2, 7 separated by a partition 6 with a port 8 normally closed by a valve 9 carried by a diaphragm 10. The chamber 2 is connected to the siren 4 through the valve 5 operated by the ejector handle, and the lower chamber 7 is connected by the pipe 11 to the train vacuum pipe. A pivoted lever 14 is connected to the diaphragm and its end may be raised by a rod 14 the lower end of which carries a framework with a shoe 19 to slide over the track ramps. The apparatus is normally in the position shown, the valve 9 being closed by the atmospheric pressure on the underside of the diaphragm 10. When the shoe passes over a ramp the diaphragm and the valve 9 move downwards. The vacuum pipe 11 is thus placed in communication with the atmosphere through the siren 4. This gives an audible signal and causes a partial application of the brakes. The operation of the brake handle to the release position closes the valve 5 and the apparatus resets itself owing to the difference of pressure on the two sides of the diaphragm.

Filed: 1969-03-10
Abstract: 1,259,967. Digital data routing. BURROUGHS CORP. 10 March, 1969 [21 March, 1968], No. 12440/69. Heading G4A. An apparatus for routing digital data among the processing elements of a computer can operate when the number of bits M in a data word is greater than, equal to, or less than the number of processing elements N. Five processing elements (PE'S) 11 are shown each holding a five bit word. Each PE is coupled to each other PE by a one bit wide path. N equals M (Figs. 3 to 6, not shown).-The words to be routed are stored in respective Registers 13 (Fig. 2) and three steps performed. Firstly four of the five bits of each respective word are transferred to the other PE'S through drivers 15 and each register 13 receives four bits, one from each of the other four words, through the receivers 17. This causes the layout of Fig. 3 to be changed to that of Fig. 4. Secondly the bits in each register 13 are shifted left or right end around by a predetermined route amount by a shift register 19 to produce Fig. 5. Thirdly the first step is repeated to give Fig. 6 where the rows of Fig. 3 have been interchanged. N greater than M (Figs. 7 and 8, not shown).- There are six PE'S each having a word of four bits, at least four of the PE'S must have drivers, receivers, registers and shifters that are six bits wide. The procedure is then as for M equals N. In another apparatus (Figs. 9, 10 and 11, not shown) an array of PE'S comprises a number of subarrays each having a number of PE'S equal to M. The corresponding PE'S of each subarray are coupled together (Fig. 10) by a bidirectional 5-bit path so that word swapping can occur. Where there are more than two subarrays the words cross to the next highest lower numbered subarray in an end-around fashion. N less than M (Figs. 12 and 13, not shown).- The bits are grouped so that there are the same number of groups as there are PE'S in the array, i.e. a 10 bit word for a 5 PE'S array is grouped into 5 two-bit groups and the routing is carried M out by groups as before. If - is an odd number N a mixture of the previous techniques is used.

Title: Means for adjusting the reading of a travel-indicator to compensate for elastic elongations in hydraulic machines, particularly in forging presses
IPC: B30B15/18
Filed: 1968-03-14
Abstract: 1,189,407. Forging presses. SCHLOEMANN A.G. 14 March, 1968 [14 March, 1967], No. 12556/68. Heading B3H. An hydraulic machine, such as a forging press of the type having a fixed and a movable part, includes a travel indicator mounted upon a stationary part of the machine, said indicator being movable in the direction of the stroke of the machine. In this way, by appropriate movement of the indicator, its reading may be adjusted to compensate for the elastic elongation of the machine when under load. In the example shown in the Figure, a rack carried by the upper movable platen of a forging press (see Figs. 1a-1c, not shown), co-operates with the pinion of a travel indicator mounted in a stationary member 6 between a piston 4 and a spring 5 having the same elastic characteristics as the machine. In operation, during the working stroke the platen actuating pressure fluid is supplied through pipe 6 to cylinder 3, thus moving the indicator against the action of the spring in the direction of the stroke by an amount equal to the elongation of the press. During the return stroke the indicator is moved in the reverse direction by the spring.

Title: Afterburning apparatus for exhaust gases from internal combustion engines
IPC: F01N13/02
Filed: 1973-03-16
Abstract: 1383881 Treating exhaust gas P AUGUST 16 March 1973 [7 Dec 1972] 12872/73 Heading FIB  A method of removing noxious constituents from I.C. engine exhaust gases comprises passing the gases through catalytic reactors and afterburners and is characterized in that after starting from cold and during the warming-up period and at vehicle speeds up to 60 km/hr, all the exhaust gas is passed through a catalytic reactor and at speeds greater than 60 km/hr, the greater proportion of the exhaust gas is passed through an atter-burner. The device comprises an after-burner formed by a central duct 6 in which the CO and CH present in the exhaust gas is oxidized by the oxygen present in secondary air admitted upstream of the device, e.g. adjacent the exhaust valves of an engine producing the exhaust gas stream. At the upstream end of the duct is a throttle valve 4 which can be closed to direct the gas into a catalytic reactor 5, through which the gas passes to a second after-burner 7. The units are enclosed in a common housing which has a heat insulating wall 14 and an internal heat conducting partition 15 between the duct 6 and the catalytic reactor 5. During the warming-up period following starting from cold, and when the engine is running light i.e. at speeds up to 60 km/hr, the exhaust gas is directed through the catalytic reactor 5. At other times, the valve 4 is opened so that the majority of the gas passes through the duct 6, the amount of gas which passes through the catalyst being adjusted to maintain the temperature of the catalyst so that it heats the duct 6 and promotes oxidation of the CO and CH. In a modification, Fig. 2, the second after-burner 7 is arranged as an annulus around the catalytic reactor 5, the gas passing upwardly through this annulus. Each of the after-burners is packed with steel chippings 13 to promote mixing of the exhaust gas with the secondary air. The chippings 13 are retained in discrete portions of the bores of the after-burners by spaced-apart perforated screens . In a second modification Fig. 4 (not shown), the catalytic reactor 5 is arranged at the centre of the housing and is surrounded by the after-burner 6. In a third modification the device consists of two afterburners, one downstream of the other, the steel chippings being coated with a catalyst, and the whole of the exhaust gas, whatever the engine operating conditions, being passed through both after-burners. Some of the exhaust gas, after passing through the device may be recirculated to the engine intake. The apparatus for withdrawing the portion to be recirculated minimises the inclusion of soot particles in the recirculated portion.
