Title: Improvements relating to x-ray analysing apparatus
IPC: G01N23/20
Filed: 1964-09-07
Abstract: 1,020,930. Diffraction apparatus. PICKER X-RAY CORPORATION WAITE MANUFACTURING DIVISION Inc. Sept. 7, 1964 [Sept. 6, 1963], No. 36584/64. Heading H5R. Diffraction analysis apparatus includes a goniostat for rotating the specimen about any of three axes, particularly about # and # axes (Fig. 2). The specimen S is mounted at the end of a goniometer head 19 (Fig. 1, not shown) which is itself carried by the # lead 17. The # head 17 is mounted on an annular, externally toothed gear member 15 which is caused to rotate within the housing 10 about the # axis, by turning handle 50 to rotate the # worm gear 33 which engages with the teeth of member 15. Rotation of the goniometer head within the # head about the # axis may be accomplished in two ways. When member 15 is stationary and the # handle 75 is turned to operate gear train 77-79, the # drive gear 81 meshes with ring member 22 which rotates within the housing 10, and operates on the gear 21 which in turn causes the worm 70 to operate on gear 71, thus rotating the goniometer. Again, if ring member 22 is stationary, rotation of the member 15 carrying the # head also causes rotation of gearwheel 21 and correspondingly the specimen. Movement of both members 15 and 22 causes # rotation at some function of the relative speeds, which can be adjusted, if required, to zero. Rotation of the specimen about the # and # axes is recorded on the odometers 74 and 63, respectively. The # odometer works through bevel gears 65 from the # drive-shaft 32. The # odometer necessarily operates using a differential 85 and is geared to the # drive through the chain 82, and, through the differential 85, to the # drive worm 33 through gears 102, 104 and 105. Special arrangements utilizing spring-urged devices (Figs. 3 and 8, not shown) enable the worms 33 and 70 to be moved from operative to non-operative positions relative to their complementary gears 15 and 17, allowing in the latter positions direct manual movement of the # head and goniometer, respectively. A computer may be used to control the 9 and # drives, instead of the use of handles 50, 75, while the odometer readings may be fed to the computer for analysis.

Abstract: 341,647. Loud-speakers. MACKINTOSH, E. V., 32, Ernle Road, Wimbledon, London. Dec. 4, 1929, No. 37235. [Class 40 (iv).] In an electromagnetic vibrating device, such as a loudspeaker, having an armature constrained to move in a direction inclined at an angle of less than 20‹ to the co-operating surfaces on the armature and a magnet pole, the stiffness of the armature support is made such that the natural frequency of the vibratory system comprising the armature and the diaphragm or other member to which it is connected, lies in the lower audible range. The construction shown comprises a magnet 1 having polar extensions 2, 3 each terminating in a pair of pole tips 4, 5 and 6, 7 respectively. Coils 8 surround the upright portions connecting the pole tips, the opposed surfaces of which are inclined as shown. The armature structure, comprising armatures 9, 10 connected by rods 11, is secured to thin strips 12, 13 anchored at each to the magnet poles, the strips furnishing the requisite small restoring force. Two opposite surfaces of each of the armatures are inclined as shown, so that these surfaces are parallel to the pole surfaces with which they co-operate. A rod 14 connects the armature structure with a diaphragm 15. According to one arrangement, the angle between the direction of movement of the armature and the co-operating surfaces of the armature and magnet poles is 15‹ and the natural frequency of the vibrating system is approximately 100 cycles per second whilst in another construction the angle is 9‹ and the natural frequency is only slightly in excess of 50 cycles per second. According to a modification, an armature co-operates with one fixed magnet pole and is itself polarized by being arranged in contact, through its supporting means, with the other pole.

Title: Switching Arrangement For The Regulation Of Circulating-Current Controlling Current-Converter Reversals
Inventor: BECK DIETRICH
IPC: H02P7/26
Filed: 1966-08-23
Abstract: 1,158,156. Control of D.C. motors. ELEKTROPROJEKT BERLIN VEB. 23 Aug., 1966, No. 37697/66. Heading H2J. [Also in Division G3] In a system in which an electric motor 15 is reversibly supplied through converters 12, 12<SP>1</SP>, circulating current through the converters is kept to a constant low value. The desired value for the circulating current is set on a potentiometer 4 supplied from a constant voltage source 5, and is applied equally to both channels; to this, in the channel appropriate to the required direction of rotation, is added a speed signal voltage U8 or U8<SP>1</SP> produced from a voltage U3 by a pair of resistors 2, 2<SP>1</SP> and diodes 3, 3<SP>1</SP>. The combined voltages U6, U6<SP>1</SP> form reference values with which actual converter current signals U7, U7<SP>1</SP> are compared to effect control of the converters by unspecified control devices 9, 10 and 9<SP>1</SP>, 10<SP>1</SP>. Thus, for a given direction, the "idle" converter passes only the circulating current as determined by 4 while the other passes this plus the motor current as determined by U3. The voltage U3 may represent the difference between a desired speed signal U1 and an actual speed signal U2. In Fig. 2 (not shown), the resistors 2, 2<SP>1</SP> and diodes 3, 3<SP>1</SP> are connected in a series/parallel arrangement. Fig. 3 (not shown) employs the same arrangement but in addition the voltage across potentiometer 4 is reduced by a signal representing actual motor current, applied through a function generator. Fig. 4 (not shown), has additional potentiometers associated with diodes 3, 3<SP>1</SP> and potentiometer 4 whereby, at high motor currents, the circulating current is prevented from falling below a prescribed minimum.

Abstract: 833,106. Cathode materials and processing. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 20, 1958 [Dec. 6, 1957], No. 37964/57. Drawings to Specification. Class 39(1). A photo-emissive surface is formed from tellurium, antimony and three different alkali metals. Preferably a tellurium layer is sensitised by caesium or rubidium and a layer of antimony, or a compound or an alloy of antimony, is then deposited on the telluride and sensitizing layers of sodium and potassium are added. A layer of tellurium is evaporated on to a glass support, this layer being sensitised by distilling caesium or rubidium on to it at 160‹C. until peak sensitivity is reached. The telluride of the sensitising metal is formed. A layer of antimony is evaporated on to this surface at room temperature. Further sensitisation is by sodium at 220‹C. until half sensitivity is achieved, and potassium at 140- 170‹C. until peak sensitivity is reached. Any two alkali metals may be used in these latter stages so long as they are different from that used to sensitise the tellurium. Antimony alloys or compounds with indium or bismuth may be used. The alloy composition should be 12 : 1 and 6 : 1 respectively for Antimony-Indium and Antimony-Bismuth. Such a surface is suitable for use as a photo-cathode in a multiplier or photo-emissive mosaic in a pick-up tube. In this latter case evaporation takes place through a stencil. The surface has an increased sensitivity in the range 4000-5500 Š compared with a known surface of antimony sensitised by two or three different alkali metals.
