Title: A plasma arc generator
IPC: B05B7/22
Filed: 1968-04-17
Abstract: 1,221,317. Cutting and welding by fusions. ROMANIA ACADEMIA REPUBLICH SOCIALISTE MANAGER OF. 17 April, 1968 [17 April, 1967], No. 18180/68. Headings B3R and B3V. [Also in Divisions B2 and H5] A plasma arc generator establishes an arc between a tungsten electrode 1 and a nozzle 2. Air or other gaseous mixture Qp introduced into the nozzle through a pipe 5 is caused to rotate by its passage through helical channels 6a. Air or other gaseous mixtures e.g. methane, hydrogen, Qs is injected through a pipe 12 and caused to rotate by its passage through helical channels a around the nozzle 2. The arc is caused to rotate by coils 8 and 10 on ferromagnetic cores 9, 11. The nozzles 2 receives D.C. through a resistor R1, cable 22, connector 23a, coil 10, screw 23b and body 18 of the nozzle. Low pressure zones are created around the electrode and the nozzle, and the arc is concentrated between the electrode and a metal workpiece P. For cutting, the gases Q P , Q S , and the arc inside and outside the nozzle, all rotate in the same sense. For welding or built up welding with a welding wire, the arc rotates in opposite senses inside and outside the nozzle, and the arc rotates in an opposite sense to the gas Q P  or Q S  inside or outside the nozzle. For metalizing or ceramic deposits, the metallic or ceramic powder is introduced through pipe 12 and channels a, which are then straight. The generator may work with or without a transferred arc gas QE, which is part of gas Q P , is evacuated through helical channels b and an ejector 19 and is reintroduced through pipe 12 with gas Q S . Cooling water circulates the electrode holder 7a, 7b by ducts 14 (15, Fig. 3), and the nozzle 2 by ducts (20, 21, Fig. 4). The generator may alternatively be used with alternating single- or poly-phrase systems. In a three-phase system (Fig. 6) the three phases (R, S, T) are connected respectively to the electrode (29) and two mutually insulated nozzles (30, 31). The nozzles have coils (32, 33) and three arcs (c, d, e) are established. A reaction gas may be introduced between the two nozzles to promote chemical reactions.

Title: Improvements relating to slicing machines
IPC: B26D1/153
Filed: 1939-06-22
Abstract: 530,392. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.Y., and Berkel, C. F. M. van). June 22, 1939, No. 18182. [Class 28 (ii)] In a slicing-machine of the type comprising a substance-carrier inclined for gravity feed, and an inclined slicing knife disposed in a plane at right angles to the direction of feed, a slicereceiver is caused by the operation of the machine to oscillate in harmony with the substance-carrier and presents a substantially horizontal slice-receiving surface forming with the plane of the inclined knife at the rear thereof a convergent slice-receiving space ; the slicereceiver is also lowered automatically to make room for successive slices. The substance-carrier 7, 8 reciprocates along guides 9, 10 past an inclined disc-knife 11 rotated by an electric motor 12. A horizontal slice-receiver 15 has a boss 40 slidable along a vertical shaft 41, but turnable therewith under the action of a rack 42 mounted on the carrier support 8 and engaged with a toothed sector 43 on the shaft 41. The slice-receiver 15 is lowered step-by-step by means of a saddle-nut 44 mounted on the boss 40 and held by a spring (with hand-release) in engagement with a screw 45, which is journalled at its ends to swing bodily to and fro as part of the same unit as the shaft 41. The screw 45 is intermittently rotated by a ratchet- and-pawl mechanism 47, 48 operated by the oscillatory movement of the slice-receiver shaft 41 and associated parts.

Title: Improvements in or relating to radar systems
Inventor: BRANDON PERCY SAMUEL
IPC: G01S13/58
Filed: 1948-07-07
Abstract: 680,704. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 22, 1949 [July 7, 1948], No. 18302/48. Class 40 (vii): In a frequency-modulated radar in which the direct and reflected signals are heterodyned to give a beat note having a frequency dependent on the distance of the target, means are provided for discriminating between targets having different relative radial velocities or for determining the magnitude and sense of the relative velocity. The invention utilizes the fact that the beat note produced by a stationary target comprises a group of harmonics of the modulation frequency whereas a moving target produces corresponding components which are displaced by the Doppler shift frequency and according to the invention the beat note is applied to a " comb " filter having a plurality of pass or rejection bands, the frequency spacing between mid-points of adjacent bands being equal to the modulation frequency. Thus, when the pass or rejection bands are centred at harmonics of the modulation frequency, the filter will pass frequency components produced by targets moving at less than or greater than a predetermined velocity which depends on the bandwidth. When asymmetrical modulation is employed, e.g. sawtooth, the components of the beat note are shifted in a direction dependent on the sense of the relative velocity and this may be utilized to determine the magnitude and sense of the relative velocity by analysing the frequency components by means of a variable comb filter or by heterodyning the components with a variable frequency and applying the resultant to a fixed comb filter. Range indication may be provided by heterodyning the filter output with a cyclically varying frequency and applying it through a bandpass amplifier and a detector to a cathode-ray tube display, e.g. P.P.I., Fig. 1 (not shown). Due to the finite response time of the comb filter, the heterodyne frequency variation should comprise spaced sawteeth, Fig. 2. Alternatively, each band of a fixed comb filter may be constituted by a plurality of separate elements each having a single narrow pass or rejection sub-band, the sub-bands of each group of elements being substantially contiguous in the frequency spectrum and the elements being connected to individual detectors indicating range, speed and sense. When using a rejection comb filter the modulation frequency should not be less than the maximum Dopple shift frequency. Specification 595,063 is referred to.

Title: Improved device for locking the control levers of carburettors of internal combustion engines in aircraft
IPC: F02D11/02
Filed: 1937-07-06
Abstract: 498,675. Spray carburetters. TAMPIER, R. July 6, 1937, Nos. 18769/37 and 1306/38. [Class 7 (iii)] In an aircraft carburetter having throttle and " mixture " levers operable independently of each other in some positions, the mixture lever may be looked in the " weak " position and be moved automatically or manually therefrom when the throttle lever is in a position in which the " normal " mixture position is essential. The throttle lever operates through a sliding rod 3 having a reduced portion in the lower face of which is an angular recess 6 opposite a recess 5 with inclined sides in the upper face of the rod. The reduced portion of the rod slides within and across a spring- pressed plunger 7 having a conical nose adapted to engage in either a recess 13 or aperture 12 in a sliding tube 4 forming part of the mixture control means. The tube is urged to the left or " normal " position by a spring 14 engaging an abutment 17 within the tube and having a lost-motion connection with a control tube 11. A conical shoulder 20 formed in the end of the tube 1 1 is adjacent the aperture 12. As shown in Fig. 1, with the throttle in the closed and the mixture lever in the normal position, the mixture lever cannot be moved as the plunger 7 is held in the recess 13 by the rod 3 which fits between the end of a fork on the plunger and a transverse pin 8. Movement of the throttle lever to the right, i.e. to the cruising position brings the recess 5 opposite the plunger 7 and the mixture lever can then be moved to the right to the weak position, compressing the spring 14; the plunger 7 enters the aperture 12 to lock the mixture control. If now the throttle is opened more, the inclined end of the recess 5 lifts the plunger 7 and the spring 14 returns the mixture control to the " normal '' position. Further movement of the throttle lever moves the recess 5 away from the plunger 7 and the rod 3 locks it in the recess 13. Two throttle rods 3 may be associated with a single mixture control 4 or the rods may be replaced by two rotatable discs co-operating with an intermediate fixed disc. In a modification, the recesses 6, 13 are omitted to give the throttle freedom of movement and the mixture control freedom unless the throttle is in the intermediate position and .the mixture control has been moved to the " weak " position. As shown in Fig. 5, a throttle lever 22 is formed with a cam member 27 having a recess 28 on its underside. A coaxial mixture lever 21 is urged to the normal position by a spring 23 and when the lever is moved to the " weak " position, a spring-pressed catch 31 thereon engages a fixed catch 30 if the throttle has been moved to its intermediate of " cruising " position permitting a roller 25 on the lever to enter the recess 28. The catch may be disengaged by depressing a knob on the mixture lever or by movement of the throttle lever displacing the roller 25 from the recess 28, the spring 23 then returning the mixture to the normal position.
