Title: Improvements in and relating to electric motors
IPC: H02K3/28
Filed: 1921-08-26
Abstract: 193,879. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 26, 1921. Alternating - current motors; windings.-In order to prevent a high speed polyphase induction motor from running at speeds considerably below synchronism, the distributed primary winding is wound with fewer conductors at the outer edges of each phase belt than would be required if the total number of conductors were evenly distributed over the entire periphery. This may be effected by omitting conductors from some of the slots at the outer edge of each coil side, or by arranging the winding so that each coil side subtends a less angle than is necessary for the complete winding to be distributed evenly over the entire periphery, as shown for a two-phase winding I, II. The winding may be a fractional pitch winding.

Title: Process for the generation of chlorine dioxide
IPC: C01B11/02
Filed: 1948-08-30
Abstract: In reacting nitrogen dioxide with a chlorite, such as sodium, potassium or calcium chlorite, to produce chlorine dioxide and the corresponding nitrite, additional chlorine dioxide is produced by reacting the nitrite with a non-volatile mineral acid, such as sulphuric, phosphoric or nitric acid, to give a mixture of nitrogen dioxide and nitric oxide, oxidizing the latter by adding excess air to the mixture and reacting the nitrogen dioxide with further chlorite.  In a continuous process, nitrogen dioxide, diluted with air, nitrogen or argon, is passed upwardly through the first of three chambers charged with chlorite, preferably admixed with porcelain saddles or broken glass tubing, and the chlorine dioxide evolved is withdrawn to point of use.  When the chlorite has been used up, the supply of nitrogen dioxide is switched to the second chamber which has previously been charged with chlorite.  Sulphuric acid is then admitted at the top of the first chamber simultaneously with air at the bottom, and the resulting nitrogen dioxide is withdrawn to storage or to the chamber being used for chlorine dioxide generation. The second chamber is then used for nitrogen dioxide production and the third for chlorine dioxide generation, while the first is being cleaned, dried and charged with fresh chlorite.  Specification 595,813 is referred to.

Abstract: 644,262. Radio signalling. M-O VALVE CO., Ltd., and CLACK, B. N. Aug. 30, 1948, No. 22840. [Class 40 (v)] [Also in Group XL (a)] One or more gas-filled electric discharge devices are connected between the primer electrode of a T-R switch and the main electrode with which the primer co-operates so as to indicate the existence of a potential difference between the primer and the main electrode. A primer electrode 8 co-operates with the hollow conical main electrode 7 of a T-R switch of the kind described in Specification 594,460, and is connected through a current-limiting resistor 12 to the negative terminal of an H.T. supply. A neon tube 14 is connected in series with resistor 15 between the primer and the earthed main electrode 7. If these electrodes are short circuited, or the water-vapour in the switch is cleaned up the neon tube 14 will fail to start, while if an unusually high voltage exists between the electrodes 7 and 8 due to the failure of the priming discharge to start, neon tube 14 will glow abnormally brightly. A circuit breaker may be provided in the neon tube circuit to ensure that the primer discharge starts before the neon tube. Specification 594,460 is referred to.

Abstract: 372,188. Position-finders. ZEISS, C. [Firm of], Carl Zeiss Strasse, Jena, Germany. Aug. 13, 1931, No. 22849. Convention date, Aug. 30, 1930. [Classes 97 (i) and 97 (ii).] Apparatus for finding the position of a target emitting short flashes of light, e.g. a gun in action, comprises means for determining the bearing and the range of the target, each such means comprising a telescope having in its field of view a layer of a light-retaining substance. The distance between the point on such layer which receives the image of the target and the optical axis of the telescope can be read on a scale. Fig. 1 shows a range-finding device having two parallel sighting lines so that two images of the target are produced. The ray pencils are received by reflectors 2, 3 and after passing through lenses 5, 6 are directed by reflectors 7, 8 into the field of view of a single eyepiece 11. A plate 10 in the field of view is provided with a layer of a light-retaining substance on the surface remote from the eyepiece. This surface is imaged in the field of view of an eyepiece 35 by reflectors 16, 17 and a lens 18. Means are provided in the field of view of the eyepiece 35 for measuring the distances between the two images of the target which are produced on the plate 10 when the target emits light. The measuring means comprises plates 23, 24 capable of being displaced by screws 25, 26. The surfaces of these plates which face each other are practically in the same plane and are provided with marks 33, 34 respectively. The plates are adjusted until the marks coincide with the two images of the target, and the distance between the marks can then be obtained from scales 31, 32 and micrometers 27, 28, the range of the target being deduced from this distance. For finding the direction of the target a telescope mounted to be moved round an azimuth scale is used, this telescope being provided with a light retaining layer and with a graticule by which the azimuth distance between any point on the layer and the optical axis of the telescope can be determined.

Title: Improvements in or relating to magnetic induction accelerators
IPC: H05H11/00
Filed: 1953-08-19
Abstract: 749,851. Magnetic induction accelerators. BROWN, BOVERI & CO., Ltd. Aug. 19, 1953 [Aug. 19, 1952], No. 22876/53. Class 39 (1). A double beam betatron in which the electrons are alternately accelerated in two opposite directions of rotation, has an orbit expansion coil L surrounding the central flux, connected over two inversely parallel connected thyratrons V1, V2 to a condenser C. The energy of one beam at expansion is regulated by adjusting the phase α1 at which the thyratron V fires, while the energy of the other beam remains constant at approximately its maximum value. The second beam is expanded by firing the thyratron V2 at phase α2= 270+#, where # is so chosen that the amplitude of the expansion pulse for the first beam is proportional to the guide flux at the instant of expansion. Acceleration of the first beam commences at phase α=0 and of the second beam at phase α=180. Fig. 3 shows the voltage UC across the condenser and UL the voltage induced in the expansion coil by the accelerating flux. From this Figure is derived the necessary expression for #. The Specification also describes the derivation of the appropriate voltages applied to the control grids of the thyratrons. Specification 656,627 is referred to.

Abstract: 855,558. Dielectric heating of foodstuffs. RADIO HEATERS Ltd. July 13, 1959 [July 17, 1958], No. 22989/58. Class 39(3). [Also in Group VI] In a method of heating, e.g. defreezing, foodstuffs are subjected to dielectric heating between electrodes the overlapping portion of which, viewed in a direction transverse to the planes of the electrodes, are wholly within the free edges of the foodstuffs. As shown, slabs of butter 4, or frozen fish, are arranged in contact with one another on a conveyer band electrode 6. The upper electrode 8 is narrower than the slabs 4, and may have adjustable plates mounted thereon by means of which its effective dimensions can be varied. The electrode 8 may be supplied with energy from a radio frequency generator mounted above the screening shell (not shown) of the oven. Overheating of foodstuffs at the beginning and end of each run can be avoided by arranging slabs of dummy material having the same characteristics as the foodstuff at each end. If desired, a balanced electrode system can be used, i.e. alternating voltages of the same order of magnitude or in phase opposition may be applied to two electrodes arranged above the conveyer.

Title: Hinge fitting for pivotally adjustably connecting a seat portion to a back rest of a seat
IPC: B60N2/225
Filed: 1974-05-23
Abstract: 1470992 Seat hinge KEIPER KG 23 May 1974 [23 May 1973] 23097/74 Heading A4J [ Also in Division F2]  In a hinge arrangement for connecting a seat to a backrest the hinge arms are pivotally interconnected by hypocycloidal gearing, the annulus being secured to one hinge arm and the planet being secured to the other, the closeness of the  mesh between planet and annulus being adjusted by varying the eccentricity of the planet axis with respect to the annulus axis. This facilitates the locking of the hinge in a desired position. In one form (Figs. 1-5) the planet axis is defined by an eccentric assembly 26, 30, 13 on a shaft 23 concentric with the annulus. The sleeve 30 has an axial cam surface coacting with a mating surface on a flange 26 which is fast with the shaft 23. Springs 34 urge the shaft to the right in order to increase the eccentricity of collar 30 and thereby ensure close mesh of annulus and planet. Leftwards movement of the shaft 23 may be achieved by:- (a) engagement of a pin 37 on a cam surface 39, Fig. 4, of knob 36, such that initial rotation of the knob causes axial leftwards movement of the shaft followed by rotation when the pin 37 engages shoulder 38 of the cam surface. (b) the rotation of an internally screwed bush (47) Fig. 5 (not shown) engaging external screwthreads on the shaft, the bush being held against axial movement. In this embodiment the actuating knob is clutched to the shaft in such manner that axial movement of the knob releases the engagement. In the disengaged position rotation of the knob causes rotation of the bush relative to the shaft. (c) a ring with a radial lever and concentric with the shaft may engage an axially acting cam face. In an alternative embodiment, Fig. 6, an eccentric sleeve 70 is mounted for rotation about an eccentric spigot 68 which in turn is mounted for rotation about pin 65 concentric with the annulus. Relative rotation of sleeve 70 with respect to spigot 68 causes variation of the overall eccentricity of sleeve 70 with respect to pin 65. Sleeve 70 is rotated by knob 74, and spigot 68 is fast with knob 76. The knobs may be rotated as a unit or the knob 74 may be declutched from knob 76 by relative axial rightward movement.
