Patent GB-139222-A (GB)
Title: Power transmission systems and mechanism
IPC: H02P9/00
Filed: 1920-02-21
Abstract: 139,222. Tanner, H. L. Dec. 18, 1917, [Convention date]. Controllers, drum; electric braking. - Power transmission is effected by two dynamo-electric machines which have different functions at different periods. During one period, which covers the low transmission ratios, the machines work simply as generator and motor; during the second period, which covers the higher transmission ratios, one machine exerts a direct magnetic torque on the other, without mechanical contact, and the currents are utilized to charge a. storage battery. Arrangements are made for starting the prime mover from the battery and for electrodynamic braking. A hand-operated drum controller makes the required circuit changes. The disposition of contacts &c. on the controller is fully described in the Specification. To obtain reversed drive, as may be required on a vehicle, a reversing drum switch 38, Fig. 14, is employed. This is interlocked with the main controller 35 by means of a slidable spring-seated bolt 47, Fig. 17. working in notches formed in disks 41 and 43 respectively attached to the main controller handle 47 and the reverser handle 44. The effect of the interlock is that the reverser can be changed over only when the main controller is in the off " or " engine starting " position. A braking action can be obtained at any time by making connexions so as to throw an electric load ou the machine D working as a generator. Depression of a pedal 64 increases the braking effect by successively cutting out resistances. A locking magnet 60 prevents depression of the pedal in case the electric load current exceeds a safe value. The pedal is preferably arranged, by means of a linkage 67 and a ratchet bar 69, to move the controller drum to braking position. When this position is reached, the ratchet is kept pressed upon the driven teeth by reaction against a stop 72, so that the controller cannot be set back by hand while the pedal is down.

Abstract: 549,492. Magnesium compounds. OCEAN SALTS (PRODUCTS), Ltd., PRYTHERCH, W. E., ANDERSON, J. H., and ADAMS, B. A. April 29, 1941, Nos. 5564, 5565 and 5566. [Classes 1 (i) and 1 (iii)] Magnesium hydroxide is obtained from brine and like waters by the following steps: lime is added to the water in sufficient quantity to precipitate calcium carbonate and magnesium hydroxide and to give a mother liquor containing magnesium ions at least equivalent to the precipitated calcium carbonate; the precipitate is separated, dried and calcined ; the calcined mixture is reacted with the mother liquor thereby precipitating magnesium hydroxide free from calcium compounds ; the precipitate is washed, dried and finally washed with fresh water. The final washing is effected in a ball mill or other grinding apparatus. The settling of the precipitate produced by the addition of lime is facilitated by the use of organic flocculating agents, i.e. alginates and humate products from seaweed, peat and lignite; shredded seaweed or a sodium hydrate or carbonate extract of seaweed are suitable materials. Specification 527,139 is referred to.

Title: Improvements in and relating to joints in structures, particularly aircraft wings orlike structures
IPC: B64C1/26
Filed: 1944-03-31
Abstract: 579,438. Joining metal plates. BOULTON PAUL AIRCRAFT, Ltd., NORTH, J. D., and CLARK, B. F. March 31, 1944, No. 5951. Drawings to Specification. [Class 20 (ii)] [Also in Groups XXV and XXXIII] Two panels or other structural elements, particularly of aircraft, are connected by a hinge of which the pin can be expanded radially to make the joint rigid. The pin is preferably in the form of a tube helically wound from strip material, which tube may contain a second oppositely wound tube. It is expanded by axial pressure produced by plugs screwed into the ends of the hinge members or by nuts on a tie rod extending through the tube; alternatively it may be initially of greater diameter than the sockets of the hinge members and be stretched axially during insertion and then allowed to resume its normal shape, in which case it may be necessary to lock it against axial extension, when in position, by transverse pins or screws or by an axial tie rod or end stops. The axis of the joint may be curved, as the pin is flexible, but in this case no hinging action is possible. The invention is described as applied to the aircraft wing forming the subject of Specification 571,990, [Group XXXIII], in which it is used for connecting the upper and lower halves of the wing together and to internal webs. Applications to aircraft fuselages, cowlings, and access panels in wing or fuselage are also mentioned.

Title: Improvements in electromagnetic releasing devices for use in automatic circuit-breakers and like electric switches
IPC: H01H50/32
Filed: 1935-02-27
Abstract: 447,791. Electrically - released switches. SADLER, A., 44, Waterloo Street, Birmingham.-(Schiele & Bruchsaler Industriewerke Akt.-Ges. ; Baden-Baden, Germany) Feb. 27, 1935, No. 6203. [Class 38 (v)] An electromagnetic releasing device, for use in automatic circuit-breakers and the like, is provided with an armatureretractive device which is energized by and during the manual closing of the switch and operates, on the opening of the switch, positively to displace the armature out of contact with the pole-pieces of the electromagnet. Any danger of the armature sticking to the pole-pieces due to residual magnetism is thereby removed. In the arrangement shown, as applied to a circuitbreaker of the leakage-current release type, the movable contact 2b is carried by a spring 2 which is flexed by a cam 3a on the operating shaft 3 when the switch is closed. The switch is locked in the closed position by the engagement of a catch with a lever 6 connected to the switch mechanism, the catch being released, on energization of a coil 1, by the attraction of the armature 1a to the pole-pieces 1c, 1d. On release of the catch, the spring 2 moves to the "off" position and rotates the cam 3a and shaft 3 in the clockwise direction. During this movement, a second cam 3b on the shaft 3 strikes an extension 1e of the armature, and positively displaces the armature from the polepieces.

Title: Method and apparatus for uniform heating of metal slabs and the like
IPC: F27D99/00
Filed: 1962-02-19
Abstract: 969,067. Continuous furnaces; manipulating furnace charges. STEIN & ROUBAIX. Feb. 19, 1962 [June 27, 1961], No. 6324/62. Heading F4B. In metal slab heating plant incorporating at least one heating zone and at least one equalizing zone uniform heating of the slabs is promoted by turning the work over through 180 degrees between the last heating zone and the first equalizing zone. The turning of the slabs is accomplished by a device comprising two sets of L-shaped levers 1, 2 mounted on parallel shafts 3, 4 which lie transverse to and just below water-cooled slipways b on which the slabs a travel under the action of the pusher c. The slab a is first lifted by upward rotation of the upstream lever 1, the lever 2 rotating at the same time in the reverse direction to meet the lever 1 before it has reached the vertical. From this point the two levers rotate together past the vertical to a point at which the lever 1 reverses and returns to its original position while the lever 2 continues with the slab " a " which is thereby deposited in an overturned position on the refractory girders g of the equalizing zone hearth. The originally upper face is heated in the heating zones to a temperature higher than the exit temperature to allow for cooling in the equalizing zone while the originally lower face is heated in the latter zone to give a final exit temperature which is the same for both faces. Cantilever type supports for the slipways (Fig. 9, not shown) serve to assist the uniform heating of the slabs in the heating zones. The shafts and levers are water or steam cooled, the shafts serving as inlet manifolds for the levers which are constructed of boiler tubes bent to the necessary shape (Figs. 17, 18, not shown). Each shaft 3, 4 is of hollow construction having a core of non-uniform diameter with a helical fin (Fig. 19, not shown), so that the cooling fluid flows along the shaft through a helical passage of rectangular section. The diameters of the sections of the core, the dimensions of this helical passageway and the diameters of the tubes forming the levers are so chosen as to give uniform velocity throughout the entire circuit. Fluid cooled bearings comprising rectangular section boiler tubes shaped to form a double cradle (Fig. 20, not shown) and lined with polished alloy steel shells support the inner ends of the shafts 3, 4.
