Filed: 1923-05-16
Abstract: 220,699. British Thomson-Houston Co., Ltd., (International General Electric Co.). May 16, 1923. Automatic circuitbrcaken; switches, quickaction. - Heating devices such as flat irons are provided with a switch in the heating circuit which is held closed against the action of a spring by a pin 18 anchored in fusible material 16. The pin 18 has an upper end which extends through a hole 47 in a pivoted member 37 and normally prevents the member 37 from rotating in a counter-clockwise direction, Fig. 3, under the influence of a catch 35 forming part of the switch mechanism, but when the material 16 melts the pin 18 tilts, the members 37 rotates, the catch 35 becomes disengaged from it and allows the switch to open, and the member 37 and pin 18 are then returned to their original positions either by a spring 46, Fig. 3, or by an extension 70 of catch 35, Fig. 8. The pin 18 is supported at its lower end on a flexible diaphragm 55 which forms the cover of a sealed well 15 containing the fusible material 16, and attached to the pin is a V-shaped perforated anchor member 59. The switching mechanism, Fig. 3, comprises a contact bridge 52 pivoted at 29, an operating member 41 pivoted at 43 and carrying the catch 35 and a member 33, and a spring 30 which by means of a link 32 pulls one end of the member 33 downwards and thereby tensions a link 34 joining the other end of the member 33 to the bridge 52. This tension normally holds the switch closed, but when the iron overheats and the member 37 can rotate, the spring 30 pulls the whole mechanism downwards, the link 34 passes the dead centre position, and the switch opens with a snap action. The switch is closed similarly with a snap action when a button 53 is pushed upwards. Specification 207,507 is referred to.

Title: Manufacture of organic oxidation products
Inventor: HAWKINS EDWIN GEORGE EDWARD
IPC: C07C409/12
Filed: 1948-05-19
Abstract: Di-isopropyl benzene is oxidized to the mono-and di-hydroperoxides by treatment with oxygen-containing gases in the substantially homogeneous liquid phase between 110 DEG  and 140 DEG  C. in the substantial absence of oxidation catalysts other than organic peroxides.  The starting material may be a pure isomer or a commercial mixture of the o-, m- and p-isomers, of which the preacts easily, the mless readily and the oto a very small extent only.  The oxidizing gas may be pure oxygen or a mixture containing it, e.g. air, and the quantity of oxygen introduced is preferably in excess of that absorbed.  Acidic by-products which p  interfere with the reaction are neutralized by adding a small amount of an alkaline substance (e.g. sodium hydroxide), preferably in the form of an aqueous solution or suspension.  The water thus added is quickly vaporized and helps to remove the acidic materials by entraining them, and at the same time the steam minimizes the risk of explosions in the gaseous phase. Extra water or steam may be added, provided the quantity is not sufficient to produce a separate liquid phase.  The various products may be separated and purified by conversion into their alkali metal salts and subsequent hydrolysis, as in Specification 641,250.  Examples are given.

Title: Improvements in or relating to electron discharge tubes with crossed electric and magnetic fields
IPC: H01J25/52
Filed: 1955-05-13
Abstract: 776,215. Travelling wave tubes; magnetrons. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 13, 1955 [May 13, 1954], No. 13970/55. Class 39(1). In a crossed field travelling wave tube or magnetron the anode segments or delay line teeth have two sides of unequal length so that electrons deviating from their mean path strike the end faces but not the sides of the segments or teeth, the end faces being at least partially directed towards the oncoming electrons. The tubes can be straight or circular and can use ladder or interdigilated lines or multicavities separated by vanes or teeth. The ends of the segments may be cylindrically concave, straight or stepped, Figs. 2, 3, 4 (not shown). The invention may be applied to a multicavity magnetron oscillator, Fig. 5, having an indirectly heated cathode 33, and to a crossed field travelling wave tube having a ladder delay line 44, Fig. 7. The invention can also be applied to backward wave oscillators with crossed fields. If the ends of the segments or fingers are not inclined as in the prior art primary electrons bombarding the sides of the fingers generate secondary electrons which absorb high frequency' power and secondary emission multiplication can take place between the sides and sides and ends of each slots, but the secondaries emitted from the ends of the fingers return thereto due to their positive D.C. potential exceeding their h/f potential and so are not harmful. The inclined ends of the fingers are therefore so arranged that the primary electrons can bombard only their end faces so that no secondaries can be generated in the spaces between the fingers. The relationships between the areas of the slots and end faces of the fingers the angle of inclination of the end faces and the angle of approach of the electrons striking the end faces, are discussed.

Abstract: 1422470 Driving vehicle wheels; measuring wheel forces R WEBER 22 March 1973 [23 March 1972] 13978/73 Heading B7H [Also in Division G1] A transducer which measures the forces and moments acting on a rotating member, e.g. a vehicle wheel, comprises two coaxial parts which fit around the shaft of the rotating member, the inner part bears on the shaft through a roller bearing while the outer part is fixed to a support. Each part has a radially extending flange which is joined to a flange of the other part by bolts which carry strain gauges and which lie parallel to the shaft. The forces acting on the rotating member are transmitted via the shaft and the roller bearing to the inner part of the transducer, thus stressing the bolts and altering the strain gauges. In Fig. 2 the inner and outer parts are shown at 11 and 10. The inner part 11 has a flange 18, seen in the upper part of the drawing, which is joined by bolt 21 to flange 17 of the outer part. The inner part has a further flange at its other end shown at 19 in the upper part of the drawing, but bolt 21 passes through that flange without touching it. The bolt 21<SP>1</SP> shown in the lower part of the drawing is diametrically opposite bolt 21 and it connects flange 19 to a flange 16 of the outer part and passes through flange 18 without touching it. An even number of such bolts are used and they alternately connect flange 18 to flange 17 and flange 19 to flange 16, Fig. 3 (not shown). The inner part 11 bears on a hollow wheel shaft 14 via bearings 12, 13, while the outer part is fixed to a support (not shown). To permit a degree of flexibility in the assembly the wheel flange 15 is driven by an intermediate shaft 38 passing through the hollow shaft 14, flexible diaphragms 36 and 37 being provided at its ends. The right hand end of shaft 38 is driven from shaft 20 via constant velocity joint 31. This flexibility allows radial, axial and flexual motion between the transducer parts. In another embodiment, Fig. 3a (not shown), the flanges are shaped such that flanges 17 and 19 lie in a plane, and flanges 16 and 18 are also coplanar. Fig. 4 shows the disposition of the strain gauges 1-6 on four bolts. Each bolt carries four gauges at its centre and two gauges at one end. Bridge circuits using various combinations of these gauges are given, Figs. 5-9 (not shown), which allow the forces P, S, U and moments M R , M S  shown on Fig. 4 to be measured. At least four bolts are required, and they may be made hollow to increase the sensitivity.

Title: Improvements relating to grinding machines

Filed: 1946-05-09
Abstract: 611,812. Grinding gems &c. STALLER, K. May 9, 1946, No. 14016. [Class 60] A machine for grinding gems or other small objects using an enlarged model of the desired finished product as a pattern, comprises a frame g which may be rocked about an axis A parallel to the face of the grinding-wheel K and locked in any adjusted position, and an axially adjustable dop f and chuck h for the workpiece D and model m respectively which are mounted in the frame and may be indexed about parallel axes B and C perpendicular to the axis A. The chuck and dop are interconnected by 1: 1 gearing o so that, when the model is indexed, the workpiece is moved through the same angle. The model is engageable by a stop l which is slidable laterally and may be adjusted vertically by a screw n operating through a lever system P which also effects movement of the grinding-wheel support through an adjusting screw r. The lever system is such that the ratio of the movements of the wheel and stop is the same as the ratio of enlargement of the model. In operation, the screw r is adjusted so that the ratio of the distances X and Y of the wheel and stop from the axis A is the same as the ratio of enlargement of the model, and the chuck h is adjusted so that the axis of the model is concurrent with the axis A. A stop t on the dop f is adjusted so as to arrest the feed when the axis of the workpiece is concurrent with the axis A. The model is then indexed and the frame g rocked until one of the faces of the model is parallel to the stop l, the frame then being locked in position. The stop l is then engaged with this face by means of the screw n, thus raising the grinding-wheel K a corresponding amount, and grinding is then effected by feeding the dop downwardly until the feed is arrested by the stop t. The process is repeated for the other faces of the model.
