Title: Improvements relating to iron castings
IPC: C22C37/10
Filed: 1924-10-01
Abstract: 245,196. Fletcher, J. E., and Young, H. J. Oct. 1,1924. Annealing, tempering, and modifyiwg physical characters of metals.-Iron castings are produced with a predominantly pearlitic structure by casting in moulds &c., the composition of the iron being regulated and metals or metalloids such as nickel, chromium cobalt, molybdenum, tungsten, vanadium or boron being added in such proportions that the metal has the required grey fracture when cast. The castings so produced are then heated to a temperature above the Ac1 point and then quickly cooled in air, oil, water, &c. so that the structure of the metal is converted into the austenitic or partly austenitic state. The casting is then reheated to a temperature not exceeding the Ac, point and quickly cooled so that the structure of the metal is converted into the martensitic, sorbitic or troositic states or a mixture of constituents possessing these characteristics. Instead of reheating the casting, the casting is removed from the quenching medium at an intermediate stage whilst retaining sufficient heat to bring about the desired structure and then cooled in air, sand or other slow-cooling medium. The heating and cooling of the castings may be effected in a bath of molten metal or molten salts. In an example, a casting containing 2.8-3.2 per cent of carbon, 0.4-1.0 per cent of manganese, 0.2-0.5 per cent of phosphorus and 0.8-1.3 per cent of silicon is referred to, and the proportion of nickel added may be 0.5-5.0 per cent.

Title: Improvements in and relating to electric discharge devices
IPC: H01J17/30
Filed: 1934-08-14
Abstract: 447,536. Discharge apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 14, 1934, No. 23448. Convention date, Aug. 16, 1933. [Class 39 (i)] A device contains, in addition to the main electrodes, an auxiliary cathode adapted to generate positive ions independently of the main discharge, and the gas-pressure is so high that the cathode drop is approximately equal to the ionization potential, the auxiliary cathode being so arranged that the independent discharge further reduces the cathode drop. In one form, in a rectifier a discharge is maintained between a thermionic or cold cathode and an anode across the path of the main discharge, the voltage drop of which is thus reduced. The gas-pressure is equal to or greater than 1 micron, for example, 3 microns. The cathode may be alkaline-, earth-, thorium- or caesium-coated. In a modification, an auxiliary cathode 24, Fig. 3, negatively biassed with respect to the main cathode 20, is arranged inside the anode 28, and the auxiliary discharge is varied by a transformer 46. The auxiliary cathode may be housed in a cylinder having a constricted aperture adjacent the main cathode. In another modification, the auxiliary cathode is arranged inside the main cathode which consists of a double-walled cylinder having heaters between its walls. The anode is then constituted by two plates closing the ends of the cathode. In a lamp, Fig. 6, the auxiliary cathode 69 is arranged inside the main cathode 63, which is heated by a filament 67 and is surrounded by heat shields. The auxiliary cathode may surround the main cathode and may be unheated if it receives emissive material sputtered from the main cathode. Specification 298,906, [Class 39 (i)], is referred to. Reference has been directed by the Comptroller to Specifications 363,914, 393,849 and 396,725.

Title: Tea-brewing apparatus
IPC: A47J31/52
Filed: 1935-08-22
Abstract: 457,944. Tea - brewing apparatus. LAWTON, N., 5, Wessington Terrace, New Washington, Co. Durham. Aug. 22, 1935, No. 23551. [Class 129] In apparatus for making tea at a predetermined time, the teapot is mounted on a movable platform which is depressed when boiling water from the kettle is syphoned over, to cut off the supply of heat. An alarm clock 27 is set at the desired time and the slotted knob 15 engaged with the alarm winder 27. When the predetermined time is reached, the winder 27 turns the rod 16 till stopped by the engagement of the plate 17 on the rod with the stop 19. This causes the switch 23 to make the contacts 21, 22, completing the circuit through the lighter filament 25 and opening the gas cock 10 by the plate 17. When the water in the kettle 29 boils, it syphons into the teapot 7. When very little water has entered the teapot, its weight overcomes that of the weight 8 and tilts the lever 5 about the pivot 3. This causes a Bowden wire 20 to move the stop 19 out of the path of the plate 17 so that the winder 27 can then turn the rod 16 till the plate 17 encounters the fixed stop 33. This causes the cock 10 to be turned off and the contact 21, 22 to be broken.. The water continues to enter the teapot by syphon action. A vent is provided in the lid 30 to ensure that only boiling water is syphoned to the teapot. The knob 15 may be turned by hand if desired.

Title: Memory device
IPC: G11C11/06
Filed: 1967-05-22
Abstract: 1,137,442. Magnetic data storage apparatus. NATIONAL CASH REGISTER CO. 22 May, 1967 [27 June, 1966], No. 23571/67. Heading H3B. A magnetic thin film data store of the type employing two storage elements per bit is provided with writing and sensing apparatus suitable for storing and reading ternary digits. The construction of the store may be similar to that described in patent Specification 1,037,205, the control circuitry being modified to handle ternary data. In one arrangement code translators employing AND and OR gates are provided to convert binary data to ternary data for storage and to reconvert sensed ternary data back to the binary form. The store requires only four storage planes to store a word in ternary form that would require six storage planes in binary form. In Fig. 9 a code translator is included in the digit plane selector 75. Binary digits applied at 77 control energization of digit drivers 40, 60 of each pair of storage planes, a " 1 " and a " - 1 " being registered by energizing one or other driver and a " 0 " by energizing neither. The two storage elements for each digit may be formed of adjacent regions of an isotropic magnetic film deposited on a conductive rod, with a word winding wound on each rod and a digit-sense winding for each storage element wound on the word winding. The storage elements each have two remanent states in one of which they are saturated in a longitudinal direction and in the other of which they are magnetized to below saturation in the same direction. If the current supplied to the word windings during read-out is less than that required to produce a permanent change in magnetization read-out is non- destructive. In this case an inhibit current is preferably supplied by the unselected digit driver 40 or 60 of a pair of storage planes during writing of a " 1 " or a " - 1." The inhibit current is equal and opposite in polarity to the normal digit current. The winding arrangement is stated to be such as to give cancellation of noise.
