Title: Improvements in or relating to valves of the velocity modulation type
IPC: H01J25/18
Filed: 1946-05-17
Abstract: 627,980. Velocity-modulated tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 17, 1946, No. 15071. Convention date, March 25, 1944. [Class 39 (i)] A velocity-modulated tube of the radialbeam, concentric resonator type is tuned by means of deformable end walls, which may simultaneously alter the width of a slot coupling the two resonant cavities. The radial beam passes from cathode K, Fig. 1, through a control grid G, through grid bars A, B associated with the buncher resonator R and grid bars M, N associated with the catcher resonator C, finally impinging on anode P, which may have a cooling jacket. Although a threaded plug T is shown in Fig. 1, according to the invention tuning is effected by deforming the flat end walls of the resonators. Instead of coupling the resonators by the loop Q, the common wall between them may have a continuous slot concentric with the axis of the device. In this arrangement, deformation of the end walls for tuning also simultaneously alters the width of this slot, and therefore the coupling, as shown in Fig. 3. The Specification as open to inspection under Sect. 91 also describes a pair of annular discs D1, D<1>1 and a further pair D2, D<1>2, Fig. 6 (Cancelled), carrying suitable potentials, which are disposed so as to focus the beam. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,005,254. Cathode-ray tube displays. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 27, 1962 [April 27, 1961], No. 15265/61. Heading H4T. Alpha-numeric characters are traced on the screen of a cathode-ray tube by a succession of straight line motions of the scanning spot. The beam deflections necessary to produce such motions are of unit magnitude but the relative magnitudes of the units for the X and Y deflections may be different to produce a desired aspect ratio. For each character the scanning spot, which starts and finishes at the centre of the screen, moves under the control of the coordinate deflection signals which may have magnitudes of 0, 1, 2, 3 or 4 units and positive or negative polarity. The beam is normally suppressed and brightening pulses which are produced only for the wanted parts of the trace have different magnitudes to ensure even illumination between traces of different lengths or traces " written " at different repetition frequencies. Fig. 1 shows the sequence in which the characters and simple recognizable shapes representative of ships, aircraft &c. are traced. A maximum of ten " legs " is provided for each character &c., the scanning spot being initially directed towards the centre of the screen, position O, to which it returns in the paths 1, 2, 3 &c. which include portions, shown as dotted lines, during which the beam is blanked off. The magnitudes and polarities of the component X and Y deflections required in tracing the various " legs " of the letter " H " together with the magnitudes of the brightening pulses B are shown in the table in Fig. 1. The various potentials controlling the production of the X and Y deflections for the different " legs " are derived by an arrangement of magnetic cores X1, X2 &c. (Fig. 2) the secondary windings N2 of each of which consists of the same number of turns (about 100) whilst the primary windings of the different cores consist of a number of turns proportional to the number of units of magnitude required for the co-ordinate deflections of each leg the polarity of which is determined by the direction of such windings. The generators for the X and Y deflections control signals are similar except that, as described above, the magnitudes of the units may be different to produce a desired aspect ratio. The generators for the brightening pulses are also similar but produce signals of positive polarity only.

Title: Improvements in or relating to backfire-preventing means for rectifiers
IPC: H01J13/50
Filed: 1932-05-30
Abstract: 406,651. Inductances. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Slepian, J. ; 1115, Lancaster Street, Pittsburg, U.S.A.) May 30, 1932, No. 15270. Convention date, July 4, 1931. [Class 37.] Relates to means for preventing backignition in rectifiers. The Specification states that the initiating cause of a back-fire is active only for a small period of time, of the order of a few micro seconds, and if the current is prevented from rising to a value sufficient to sustain an arc during a period slightly greater than the active period, the backfire will be prevented from becoming effective. The means consists of a reactance designed to saturate at a very low value of current (smaller than that necessary for a self-sustaining arc) the time taken to saturate being greater than the period of activity of the back-fire initiating cause. This reactance is connected in series in the anode lead. A theoretical discussion of the design of such a reactance together with a consideration of the effects of eddy currents on the design is given in the Specification. Fig. 3 shows the response curve for such a reactance in which the current is plotted to a time base, and it will be seen that the current remains practically constant at a low value during an initial time period. Since the reactance has to stand the full load current it is preferably constructed in the form of a single layer winding on a ring core. This core may be reduced in cross-section at one point in order to adjust the saturation value. In a multi-phase rectifier, Fig. 5, two anodes may be fed from a single phase through a reactance 51 designed as above but having two windings arranged so that they are non-inductive when the anodes are normally conducting current. Since the self-capacity of the winding may effect operation various means are employed to counteract this. In Fig. 12 the winding 80 is completely embedded in the core which is composed of slotted laminations 78 and ring laminations 81, 82. In a modification, Fig. 13, the turns 84 are uniformly spaced between the core 85 and a shield 86. In a further modification, condensers are connected between the turns and one end, and in another modification between the turns. Since a high potential is built up across the reactance during the back-fire initiating period, protective means are provided such as lightning arresters connected between the grids or resistances or condensers connected between the anodes and cathode.

Abstract: 186,659. Marks, E. C. R., (Akt.-Ges. fiir Tiefbohrtechnik und Maschinenbau Vorm. Trauzl & Co.). June 2, 1921. Regulating.-In Diesel engines, particularly motor-car or marine engines, in which the quantity of fuel injected is regulated by hand, the moment of opening, and if desired also the amount and duration of opening, of the fuel-injection valve is varied automatically according to the speed by means of a speed regulator or the variable pressure occurring in the suction pipe or the cooling-water pipe. In the form shown, the stroke of the fuel pump 19, actuated by a cam 21 and lever 22, is varied bv means of a handwheel 24 and screw 25. The cam 29 actuating the fuel-injection valve 5 is formed tapering, as shown in Fig. 2, and is moved axially by the governor 30 so as to cause the valve to be opened earlier at high speeds than at low speeds. The lift of the valve is also increased, and by making the effective length of cam-surface increase also, the duration of opening will also become greater as the speed increases.

Filed: 1949-06-14
Abstract: Linear co-polymeric siloxanes of the formula <FORM:0659012/IV (a)/1> where n is a positive value and R is a methyl or ethyl radical, are made either by mixing, co-hydrolysing and co-condensing the silanes (CH3)3SiX and/or C2H5(CH3)2SiX and CH3. C2H5SiX2, where X is a halogen or alkoxy radical, or by separately hydrolysing the above silanes and mixing and co-condensing the resulting siloxanes by contacting them with an interaction catalyst.  When n is an integer from 1 to 4 the products are distillable and above 4 they are non-distillable.  In the former method, the reaction may be effected with or without catalysts, with or without solvents and at temperatures between 0 DEG  and 250 DEG  C.; in the latter method the preferred temperature is between 80 DEG  and 200 DEG  C.  In examples: (1) ethylmethyldichlorosilane is co-hydrolysed and co-condensed with trimethylchlorosilane and the resulting product fractionally distilled to give four fractions of the formula <FORM:0659012/IV (a)/2> in which n is 1, 2, 3 and x; (2) a cyclic ethyl-methylsiloxane is condensed with (CH3)3SiO Si(CH3)3 in the presence of concentrated sulphuric acid and the product is fractionally distilled after washing, drying and filtering; (3) ethyldimethyl end blocked siloxanes are made by co-hydrolysing and co-condensing ethyldimethylchlorosilane and ethylmethyldi-chlorosilane.  The products are liquids freezing below - 120 DEG  C. and may be used as lubricants and damping media for use in aircraft.

[Class 118 (ii).] A manoeuvre signalling device for motor vehicles comprises an upper arm section 4 in the form of a flat tubular member rigidly secured through the sleeve 8 and a pin to the rotatable shaft 7, and a fore-arm section 5 with hand 6 in the form of a flat tubular member fixed to the shaft 10 rotatably mounted in the upper arm member 4. A sleeve 14 is pinned to the shaft 10 and has rigidly secured thereto two arms 15, 16, the one 15 being connected by a spring-link connection 24a, 25, slack when the members 4, 5 are vertical, to an eye 24 on the member 23, and the other 16 being connected by a spring 17 to the bracket 18. The member 23 extends outwardly from a sleeve 22 clamped on a rotatable shaft 19 having the member 20 extending from one end thereof to engage with a cam 27 rigidly secured to the shaft 7. The members 4, 5 are provided with stops 11, 12, 13 to limit their relative rotations. Rotation of shaft 7 to a first signalling position rotates the member 4 and the member 5 relative to the member 4, the spring 17 overcoming the spring-link connection 24a, 25. Further rotation of the shaft to a second signalling position rotates the member 4 to a horizontal position and causes the cam 27 to rotate the member 20, shaft 19 and member 23 clockwise to cause the spring- link connection 24a, 25 to overcome the spring 17 and rotate the member 5 into horizontal alignment with the member 4. Further rotation of the shaft 7 to a third signalling position rotates the member 4 to a position below the horizontal, the cam 27 still engaging the member 20 and the member 5 remaining in alignment with the member 4. The shaft 7 is rotated to the different signalling positions through the lever and bell crank system shown in Fig. 1, the lever 28 being fixed to the shaft 7 and the system being operated by hand from the handle 40, a spring-pressed locking dog 41 engaging notches 39 corresponding to the different signalling positions.

Abstract: 612,629. Coin-freed apparatus. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., and HASTED, H. C. May 28, 1946, No. 16098. [Class 27] Coin action, weight and multiple-coin; testing coins.-Mechanism requiring simultaneous insertion of coins to a predetermined value in each of a plurality of denominations comprises a plurality of weighing scales for the different denominations, and interlocks between the scales such that partial tipping only is permitted until all the scales have been partially tipped, this occurring when each has rereived the required number of coins of its respective denomination, whereupon all the scales are released by the interlocks for a full tipping movement to discharge the coins. One or more of the coins so discharged may then free the associated apparatus, e.g. a vending machine or a turnstile, or the said full tipping movement may itself free the apparatus. In Figs. 1 and 4 a pair of scales 2 and 3, pivoted on parallel axes 4 and 5 and provided with screw-threaded adjustable counterweights 7 and 11, are arranged to receive coins passed to them by way of insertion chutes 16 and 17. The interlock between the scales comprises an arcuate member 21 connected by a radial arm 22 to the scale 2, and a similar arcuate member 24 carried by the scale 3. These arcuate members are relatively disposed as shown (see Fig. 4) and allow a small partial tipping of either scale alone limited by the leading edge 30 or 26 of the corresponding member abutting the tail 29 or 27 of the other. When both scales have been partially tipped under the weight of the required coins, the tail of each arcuate member moves clear of the leading edge of the other so that both scales are released for a full movement which discharges the coins to lower chute sections 12 and 13. In a modified interlock (Fig. 13), full tipping of either scale is prevented by engagement of a part 26 of an abutment 36 secured to it, under a stop 31 projecting from a respective weighted lever 32 pivoted at 33. A cam part 34 on each lever is engaged by the other scale when partially tipped, and this rocks the lever to clear its stop 31 from the abutment 26 of the first mentioned scale so freeing it for full movement. In this way both scales tip fully to discharge their coins only when both have received their full weight of coins. The two levers 32 are pivoted on a common axis 33 to depend between the two scales which are arranged coaxially. Clearing-apparatus.-The upper chute sections 16 and 17 are pivoted at 14, 15 and can be rocked by the operator to sweep the coins off the scales to a return chute if they fail to tip the scales and operate the associated apparatus.
