Title: Improvements in or relating to television receivers
IPC: H04N5/64
Filed: 1949-07-18
Abstract: 662,114. Television. MULLARD RADIO VALVE CO., Ltd., BIRKBECK, G., and PHILLIPS, S. J. July 18, 1949, No. 18913/49. Class 40 (iii). A cabinet for a television receiver of the type in which a picture image is produced by optical projection'on to the back of a translucent screen 21 along a projection axis which is substantially horizontal, comprises a part 15 carrying the screen and pivoted to the main body of the cabinet at 22 so as to be movable from a closed position (Fig. 2, not shown) in which it is partially housed within the body to an open position (as shown) in which the screen is brought to the correct viewing position in relation to the cathode-ray tube projection apparatus 12. A spring-urged flap 30 engages the face 18 of part 15 and ensures that no opening into the cabinet occurs with the pivoted part in the open position. In an alternative construction of part 15, the edge between faces 17 and 18, and the rear edge of face 18 are of equal radii from pivot 22 so that the edges coincide with the forward edge of top 29 in the open and closed position respectively. In a further alternative construction, face 18 of part 15 is omitted and a flap of equal size is pivoted at the front edge of top 29, the flap occupying the place of face 18 and enclosing the apparatus when the pivoted part is in the open position, and covering the screen 21 when in the enclosed position. An on-off switch is operated by the pivoted part to switch on the receiver when the part is moved to the open position. The operating controls are carried by the pivoted part so that they are concealed within the body when the pivoted part is closed.

Title: Process for the production of bipyridyls
Inventor: BAINES ALBERT
IPC: A01N43/40
Filed: 1961-05-26
Abstract: The invention comprises 2,21-dimethyl-4, 41-bipyridyl and 2, 21, 6, 61-4, 41-bipyridyl. These with other bipyridyls are manufactured by treating a pyridine with sodium at a temperature of at least 50 DEG C. and oxidising the sodium-pyridine interaction product so formed. Preferably the pyridine is treated with sodium at a temperature in the range 75-100 DEG C. The sodium may be dispersed in a liquid medium, e.g. a petroleum fraction or an alkylated benzene. The oxidation may be carried out by means of molecular oxygen or chlorine. The mixture may be heated after the oxidation in the presence of water to precipitate sodium hydroxide (sodium chloride if chlorine is used as oxidising agent). Examples are given of the preparation of bipyridyl, 2,21-dimethyl-4, 41-bipyridyl and 2,21, 6, 61-tetramethyl-4, 41-bipyridyl.

Reciprocating machines.-The rock-shafts 6 of a massage machine are rocked by means of electromagnets 3 having horizontally reciprocating armatures 4 which are connected to the rock-shafts and themselves effect periodically an inversion of the current supply to the electromagnets. The electromagnets are controlled for alternating actuation by a pivoted lever 16 connected to extensions 12 of the armatures 4. The main switch is actuated by relays 18 controlled by an automatically actuated switch 19 connected by a link 21 to the lever 16. The switch 19 has a pair of contacts, one connected to one of the relays 18 while the other is connected to the other relay. In association with a manually operable switch 251, contacts 1, 2, 3 are arranged, upon which the switch may be selectively positioned to control thereby the automatically acting switch so that the main switch is moved to circuit-closing position at an earlier or later instant in the movement of the armatures.

Title: Manufacture of iron and steel and products obtained thereby
IPC: C21C1/00
Filed: 1952-07-31
Abstract: Alloy steels, particularly stainless steels, are produced in a fine-grained, low-sulphur form by preparing an iron-containing melt, adding the alloying constituents, e.g. Cr, Mn, Mo, Ni, W, Cb, Co, Ta, Ti, Zr and Si. to it during furnacing, deoxidizing and adding a composition consisting of a rare earth oxide, or plurality of rare earth oxides, and a reducing agent.  The term "rare earth oxide" includes the carbonate, chloride or silicide and the reducing agent may be selected from the group: Ca, Al, Ni, Mg, Si and B and a boride, borane or silicide of Ca, Sr, Mn, Cr, Fe, Mg, Ni, B and Co. The composition consists of 1 part of oxide and 0.2-1 part of reducing agent and an oxygen-containing source, e.g. a nitrate of Na, K, Ca and Mg may be added in an amount from 60-70 per cent. of the weight of the reducing agent.  The mixed and briquetted composition is added to the melt, at the rate of 1-5 lbs./ton of steel, before, during or after deoxidizing.  If the melt is poured in a ladle, the composition is added before the ladle is half-full or is initially placed on the bottom of the ladle and covered with calcium silicon deoxidizer, or put in a thick-walled closed pipe which is placed on the ladle bottom, and the melt then poured on top.  The rare earth metal content of the resultant alloy should not exceed 0.018 per cent.  The preparation of alloys consisting of: C 0.07 per cent., Mn 1.73 per cent., S 0.025 per cent., P 0.015 per cent., Si 0.52 per cent., Ni 20.8 per cent., Cr 24.7 per cent. Cu 0.26 per cent., rare earth metals 0.005 per cent., balance Fe; and C 0.11 per cent.; Mn 1.72 per cent., S 0.007 per cent., P 0.02 per cent., Si 0.46 per cent., Ni 20.7 per cent., Cr 24.9 per cent., Cu 0.26 per cent., rare earth metals 0.005 per cent., balance Fe; and alloys within the ranges: C 0.26-0.31 per cent., Mn 1.71-1.92 per cent., S 0.026-0.03 per cent., P 0.011-0.019 per cent., Si 0.21-0.26 per cent., Mo 0.43-0.47 per cent., rare earth metals 0.005 per cent., balance Fe; are described.
