Filed: 1922-12-30
Abstract: 213,338. Guttmann, N. Dec. 30, 1922. Cigarette-making machines.-In a machine of the tube-filling type, the cigarette tube is received by a holding-apparatus by which it is held and guided until the finished cigarette is delivered. The cigarette tubes are held in chambers a having feet which slide in V-grooves f in a block d mounted on a shaft e, the ends of the slots being closed by cheeks f<1>, f<2>. Each chamber g contains a stationary cheek h and a movable jaw i, Fig. 2, controlled by a spring i<1>. The jaw i is operated by a bell-crank lever l, an adjusting- screw k enabling the distance between the jaw i and cheek h to be varied so that the filled cigarette is held gently. The jaw i and cheek h are removably mounted and interchangeable to make cigarettes of different sizes. The cigarette tube is inserted into the chamber g when this is in the position w, Fig. 2, and bearing against the stop f<2>, Fig. 1, the jaw i being, held open by the engagement of the bell-crank lever l with a cam-rail m. The tube is cut off by shears and the shaft e rotated through 90‹, bringing the chamber g into the position s, Fig. 2, in which it is in line with the filler rod c, Fig. 1. A push-rod n bears on the foot of the chamber g, a projection n<1> at the same time bearing on the bell-crank lever l and releasing the cigarette tube, which is pushed by a stop p<1>, moving simultaneously with the push-rod n, on to the filling-member of the filling device, on to which it is pressed by an abutting member b, the chamber g being at the same time moved into engagement with the stop f<1>. The required quantity of tobacco is pushed by the filler rod c into the cigarette tube, t'he stop p<1> simultaneously receding into the position shown dotted, to act as a stop for the projecting tobacco filling. The abutting member b then releases the filled tube and the push-rod n releases the bell-crank lever l, causing the cigarette to be firmly held. A plunger o, moving simultaneously with the movement of the filler rod c, then engages the foot of t'he chamber g and moves this into engagement with the stop f<2>. The shaft e is then rotated through 90‹, bringing the filled cigarette into the position t, Fig. 2, in which the ends are cut. A further rotation of the shaft e through 90‹ causes the cigarette to be brought into the ejecting position u, Fig. 2, the bell-crank lever l being operated by the cam-rail m to release the cigarette, which is ejected by a rod v with a cleaning-brush v<1>, or by a gripping device. The length of the cigarette may be altered by simultaneously adjusting the block d on the shaft e, the plunger o, the stop p<1> and the push-rod n.

Title: Arrangements for modulating high frequency oscillations
IPC: H03C7/02
Filed: 1937-12-23
Abstract: 490,990. Valve modulating circuits. LORENZ AKT.-GES., C. Dec. 23, 1937, No. 35685. Convention date, Dec. 23, 1936. [Class 40 (v)] High frequency currents are modulated by varying the internal resistance of a valve included in an oscillatory circuit which is coupled to an oscillation generator or its load. The oscillatory circuit 2 of the magnetron generator 1 is coupled to the radiation dipole 6 by means of the Lecher system 5. An oscillatory circuit 7 consisting of the inductance 8 and the capacity of the split-anode tube 9 is coupled to the Lecher wire in series with the load 6. The cathode 12 of valve 9 and the centre tap of inductance 8 are earthed, and modulation applied to the grid 11 varies the attenuation of the oscillatory circuit 7 and thus the power supplied to the load. The circuit 7 may be coupled symmetrically to the Lecher system or may be coupled directly or through an additional oscillatory circuit to the oscillator 1. The modulating potentials may be applied to the anode of the modulating valve which may have a magnetic field or may be replaced with a simple diode or triode. Reference has been directed by the Comptroller to Specification 466,082.

Patent GB-358190-A (GB)
Abstract: 358,190. Cables. CALLENDER'S CABLE & CONSTRUCTION Co., Ltd., HUNTER, P. V., Hamilton House, Victoria Embankment, WATSON, J. F., Preston Lea, Woolwich Road, Abbey Wood, and BRAZIER, L. G., Hamilton House, Victoria Embankment, both in London, Aug. 11, 1930, Nos. 23988/30, 24953/30, 25491/30, 25624/30 and 1440/31. [Class 36.] A single core cable 1 is built up with impregnated layers of insulation 3 such as helically lapped paper on the conductor, the insulated core having a non- circular form in cross section, e.g. an elongated ellipse, a triangle or four-sided figure with rounded corners and, advantageously, slightly convex sides. The non-circular form of the core is preferably obtained by applying insulation to a non-circular conductor 2, or strips of insulation may be applied to a circular conductor so as to form a non-circular base on which the insulation layers may be wound. The conductor may be formed of a non-circular configuration which rotates about the conductor axis along its length as shown in Fig. 6. A lead sheath 6 surrounds the core and contacts lightly with a conductive layer 4 wrapped over the core insulation. The lead sheath may be non-circular to fit the core, or a circular lead sheath 6 may be applied, the clearance 7 thus formed being preferably filled by compound and a quantity of inert gas which may be contained in flexible walled vessels. Filling pieces may, however, be arranged round the core to enable a circular lead sheath to fit closely. A small radial clearance may be left between the core and the sheath, and, in order to maintain the layer 4 in electrical contact with the sheath 6, a metal tape 14 with springy projections 15, Figs. 4 and 5, may be wound on the core, the projections 15 extending inwardly towards the layer 4. The projections 15 may be produced by stamping up the centre part of a tape 14, or a metallized fabric or paper tape may be threaded through by a wire or metal strip. The tape 14 may be applied as an open helix. Three of the Provisional Specifications describe multicore cables of non-circular section with a space between the core and lead sheath which is preferably filled partly with compound and partly with inert gas, flexible vessels enclosing the gas and conductive layers with springy projections for bridging the space between the core and sheath also be referred to in connection with multicore cables. Specification 350,714 is referred to.

Title: Balancing Apparatus for Rotatable Bodies
Inventor: HAYES STEPHEN VIPAN
IPC: G01M1/36
Filed: 1966-08-10
Abstract: 1,186,676. Balancing rotary members. NATIONAL RESEARCH DEVELOPMENT CORP. 3 Aug., 1967 [10 Aug., 1966], No. 35819/66. Heading F2U. Relates to means for dynamically balancing a rotating body 1 by masses which cannot conveniently be located in the same radial plane as that of the body and hence would otherwise produce an unbalanced couple. For this purpose pairs of masses 7, 11 and 8, 12 are arranged in spaced planes on a hollow shaft 2 attached to the body 1, each mass of each pair having an equal moment about the axis of rotation as the other mass of that pair, masses 11 and 12 being secured to an inner shaft 9, and masses 8, 7 to an intermediate concentric sleeve 4. By turning the four masses together relative to the body 1 during rotation, the plane of the couple they produce can be brought into coincidence with the plane of the unbalance in the body 1, as indicated by minimum unbalance. The pairs of masses can then be turned relative to each other to vary the magnitude of the unbalance of the mass pairs until it balances that of the body which is then balanced for forces and couples. The masses may also be axially movable. The shafts 4 and 9 are rotated by an electric motor 13 through pinions 16 and 17 and worm gears 25, 27 and 31, 33 respectively, engagement of an electromagnetic clutch 18 driving the shafts in the same direction, and engagement of clutch 22 driving the shafts in opposite directions.

Title: Improvements in and relating to telegraph transmitters
IPC: H04L17/06
Filed: 1936-12-31
Abstract: 491,491. Type printing telegraphs. TELEFONBAU UND NORMALZEIT AKT.- GES. Dec. 31, 1936, No. 35877. Convention date, Dec. 31, 1935. [Class 40 (iii)] In a telegraph transmitter of the kind having motor driven contact actuating members which are set by intermediate members which are themselves set by permutation members, the permutation members are provided with springs by means of which they are selectively moved when a key is depressed and auxiliary mechanism, set by the depression of a key, holds the intermediate members in the position in which they are set by the key until the setting of the contact actuating members in accordance with the setting of the intermediate members has been completed. Depression of a key tilts a latch 15 to release a stop bar 10, pivoted on a rod 11, under the action of a spring 19. This allows such permutation bars (a-e) as are not held by the depressed key to move to the right so tilting corresponding levers 32 (a-e) about their pivots. The movement of the stop bar 10, by means of an arm 43 and lever 50, also causes the depression of a plate 55 and five associated hook-shaped members 51 (a-e) each of which holds its corresponding lever 32 in the actuated or unactuated position. The arm 43 also allows, by pawl mechanism 40, one revolution of the contact operating shaft 22. This carries five discs 29 (a-e) capable of slight movement relative to the shaft 22 and so mounted that when a projection 34 strikes a corresponding projection 33 on a lever 32 this movement takes place against the action of a spring 31 and the appropriate rod 28 (a - e) is allowed to shoot forward under the action of a spring 27 (a-e) carrying with it a contact operating cam 23 (a-e) as described in Specification 389,999. After being set by the levers 32 the discs 29 force these back against springs 35 and pass them. Signal impulses are sent during the remainder of the revolution by means of the cams 23 and immediately the discs have passed the levers 32 the latter are unlocked and restored to their normal position by cam mechanism Fig. 1 (not shown) operated by the driven shaft 22. The contact cams and discs are reset in their original positions after actuating the contacts. If a second key is depressed before the first revolution is completed it serves merely to set and lock the intermediate levers 32 in the new position until these have reset the contact operating discs.

Title: Continuous process for cracking hydrocarbon oil
IPC: B01J8/38
Filed: 1962-09-27
Abstract: In a process for the fluidized catalytic cracking of hydrocarbon oils to gasolines in which a mixed fresh and recycle oil feed is contacted with catalyst in a reaction zone and catalyst is regenerated in a separate regeneration zone by contact with an oxygen-containing gas, the contact time of hydrocarbon and catalyst and the reaction temperature are adjusted according to the feed to produce a coke deposit on the catalyst such that a temperature of at least 620 DEG C. is maintained in the regeneration zone and the flow of oxygen into the regeneration zone is controlled responsive to the difference in temperature between the catalyst section and the gas outlet section of the regeneration zone to maintain a predetermined temperature difference, whereby the oxygen content of the outlet gas is minimized and after-burning (combustion of carbon monoxide) precluded.  The operating variables controlling coke deposition are fresh feed temperature, catalyst circulation rate, fresh feed to recycle oil ratio and space velocity.  The regeneration zone temperature is maintained at 620-677 DEG  C. and the gas outlet temperature generally not more than 14 DEG  C. higher.  At the high regeneration temperatures used this temperature difference gives an indication of the oxygen content of the flue gas and by trial and error the necessary difference is found and thereafter maintained corresponding to an oxygen content below 0.2%.
