Title: Method of, and apparatus for, accelerating ionized gas
Inventor: CONSOLI TERENZIO
IPC: H05H1/54
Filed: 1964-04-27
Abstract: 1,015,734. Linear particle accelerators. COMMISSARIAT A L'ENERGIE ATOMIQUE, and BOEING CO. April 27, 1964 [April 29, 1963], No. 17403/64. Heading H1D. [Also in Division F1]  Charged particles are accelerated in a given axial direction by simultaneously subjecting them to a transverse electric field of frequency f and having a gradient in the axial direction, and to an axial magnetic field varying in the axial direction in such a manner that, if f c  is the corresponding cyclatron frequency, then fc/f > 1 where the magnetic field and the gradient of the electric field have the same sense, and fc/f < 1 where they have opposite senses. Charged particles from a source 4 are directed through a quartz tube 8A which passes through a cavity resonator 11A in which a high-frequency transverse electric feed, of frequency f, having a halfwavelength equal to the length of the cavity resonator, is maintained by a source 6. It is stated that, if a uniform axial magnetic field B is present in the cavity, the mean axial force F acting on a particle, e.g. an electron, is given by F = - e<SP>2</SP>#(E<SP>2</SP>)/4mw2(1-b<SP>2</SP>) where b=fc/f, and fc is the   cyclytron frequency eB/2#mc. Thus, if B is   arranged to be non-uniform in the axial direction, in such a manner that (1 - b<SP>2</SP>) changes sign when V (E<SP>2</SP>) changes sign, the particles may be accelerated continuously throughout the length of the resonator. A D.C. energized coil 5, or a permanent magnet, provides the non-uniform magnetic field, decreasing linearly from end 2 to end 3, the corresponding cyclatron resonance frequency being arranged equal to f at the centre plane of the cavity, where the axial gradient of the transverse electric field changes sign (Figs. 2 and 6, not shown). The method may be employed for accelerating electrons, ions, or a plasma, in the latter case the ions of the plasma being accelerated by the space charge of the accelerated electrons. The accelerator may be used for jet propulsion; for injecting accelerated particles into the two ends of the magnetic bottle of a nuclear fusion apparatus (Fig. 4, not shown), or for producing a high vacuum, by connecting its inlet to the vessel to be evacuated and its outlet to a backing pump, and employing an electromagnetic field sufficiently intense to ionize the gas flowing through the tube 8A (Fig. 5, not shown).

Title: Method of Kerfless Cutting of Wood.
Inventor: COLLINS ERNEST HOBART
IPC: B27M1/00
Filed: 1967-04-17
Abstract: 1,187,063. Woodworking. WEYERHAEUSER CO. 17 April, 1967, No. 17444/67. Heading B5L. A method of severing wood comprises reciprocating a knife at a predetermined frequency and stroke along a line inclined to the knife edge and passing the knife through the wood to be severed, the temperature of the knife being regulated by the speed of the wood moving relative to the knife. The temperature of the knife may be from 150‹ F. up to the metallurgical limit of the knife material and causes plasticizing of the layers of the wood at the cut face thus reducing the risk of splitting. The knife may be heated by an electric current. In apparatus for carrying out the method, the wood is fed by rollers 34, 36, Fig. 1, between side pressure rollers 35 adjacent the knife 37 which is reciprocated in an inclined direction at up to 50 c.p.s. through a stroke of 1 inch by hydraulic mechanisms 40, 41 which also act to tension the knife. In another embodiment, the wood is fed along a feed table 49, Fig. 2, by rollers 55 to a pair of knives 75, 78 carried by arms 60, 61. Each arm is mounted at one end on pivots 67, 72 and at the other end connected by rods 85, 86, 93, 94 to a crank-shaft 89 driven from a chain drive 100. The knives are reciprocated at 60 c.p.s. with a stroke of 0À3125 inch. Side pressure rollers 57 prevent splitting of the wood. In a further embodiment, the wood 176, Fig. 4, is fed through the apparatus by rollers 114, 115, 122, 123 and first passes between pairs of scoring knives 137, 152, 138, 153, 139, 154 which successively cut deeper into the wood and are reciprocated in a vertical direction by mechanisms 128, 129, 130 and 143, 144, 145. The wood then passes between upper and lower rollers 158, 159 and side pressure rollers to a knife 170 which severs the wood and is vertically reciprocated and tensioned by mechanisms 166, 173. In a final embodiment, the wood 193, Fig. 7, is fed along a table 185 to a knife 191 connected to upper and lower ultrasonic generators 187, 189 which reciprocate the knife through a stroke of 0À006 inch at 25,000 c.p.s. Alternatively, each generator may be connected to respective blades each of which extends approximately half way through the wood.

Title: Improvements relating to Signalling Lamps, Aircraft Recognition Lamps, Motor Vehicle Headlights and the like.
Inventor: ALDIS ARTHUR CYRIL WEBB
IPC: F21V7/04
Filed: 1918-10-25
Abstract: 134,281. Aldis, A. C. W. Oct. 25, 1918. Signal, vehicular, and like lanterns.-A lightprojecting apparatus, for use as a signalling or aircraft-recognition lamp or motor-vehicle headlight, comprises a small source of light such as an electric focus bulb a, Fig. 1, having a closelywound spiral filament b and a spun metal or other reflector c shaped so that an inner parabolic zone 1, 2 reflects the light parallel to the axis of the reflector and the outer zones 2 - - 5 reflect the light at different angles to the axis of the reflector. The light reflected from the end zone of the reflector is at an angle equal to the maximum angle of the direct light from the bulb, which angle is limited by the diameter of the open end of the reflector. A portion of the inner end of the reflector approximately equal in size to the lamp bulb is not used as a reflecting-surface and may be occupied by the bulb socket. In motorcar head-lights, parts of the reflector reflecting light upwardly and outwardly may be blackened to prevent gla.re. In recognition lamps, the reflector terminates at its inner end in a cylindrical pocket containing the bulb-holder, and at its outer end is adapted to receive a removable coloured screen secured by a detachable metal ring. An annular hood extends beyond the screen. The bulb is formed with a metal stem h, Fig. 3, provided with a collar i having radial projections j. The collar is inserted through a correspondingly-shaped aperture in a plate k fixed in the bulb-holder, and is locked by partial rotation. The collar and plate form one electrical connexion, and a spring plunger l contacting with a central terminal on the bulb forms the other. The Provisional Specification states that, by means of the collar, the lamps may be conveniently standardized so as to require no adjustment relatively to the reflector after insertion.
