Title: Teletypewriter apparatus
IPC: H04L12/04
Filed: 1939-04-06
Abstract: 527,335. Type-printing telegraphy. STANDARD TELEPHONES & CABLES, Ltd. April 6, 1939, No. 10789. Convention date, April 7, 1938. Drawings to Specification. [Class 40 (iii)] Type-printing telegraph apparatus comprises two units, one consisting of a keyboard and message recorder and the other, at a separate point but electrically connected therewith, consisting of permutation code sending and receiving means. The keyboard unit comprises the keyboard itself together with either (i) contacts individual to each key for energizing a selection of relays for code transmission (Figs. 9 and 10, not shown) or (ii) code bars each having an associated contact for code transmission (Figs. 9A and 10A, not shown). The contact distributer (Fig. 10, not shown), on the cam distributer (Fig. 10A), and its driving means are situated at a point remote from the keyboard and are connected to it by a wall jack. The decoding means of the receiver are also situated at the remote point and comprise a start-stop distributer, a set of receiving relays and a set of transfer relays (Fig. 11, not shown) which control a set of fanning-out relays (Fig. 12, not shown), which in turn control a cross-bar or co-ordinate switch (Fig. 13, not shown). The contacts of this switch selectively operate a set of character-forming relays (Fig. 14, not shown) which energize combinations of magnets in the keyboard unit to control the message recorder. Each magnet causes a needle to be pushed through a paper tape, the relative positions of the selected needles forming the outline of the letter (Figs. 5, 6, 7, not shown). Instead of perforating a tape, the needles may press a carbon tape against it, or cause marking electro-chemically.

Patent GB-758395-A (GB)
Title: Condensation products of arylhydrazines
Inventor: MILLER JOHN
Filed: 1954-04-14
Abstract: Condensation products of arylhydrazines with reactants capable of reacting therewith, namely aldehydes, ketones, urea, cyanates and thiocyanates are prepared by heating an aqueous solution of the corresponding sodium or potassium arylhydrazine-N-sulphonate with sulphuric or preferably, hydrochloric or hydrobromic acid, neutralizing the excess of acid over one molar equivalent, e.g. with sodium or potassium hydroxides, adding the reactant (i.e. the substance with which condensation is to take place), if necessary heating until condensation is complete and isolating the product. In the arylhydrazine-N-sulphonate the aryl group may be phenyl or a - or b -naphthyl or a suitable substituted derivative thereof. The N-sulphonates are prepared by alkali metal sulphite reduction of aryldiazonium salts and the crude liquors thus obtained may be used, although the solid recrystallized N-sulphonates are preferred. Preferably two molar equivalents of acid are added to the N-sulphonate solution, the mixture refluxed for 1-2 hours, the excess acid over one molar equivalent neutralized with caustic alkali to about pH3 and the reactant added.  When the free arylhydrazine is required for condensation the acid liquor is neutralized to about pH 8.  In examples, (1) sodium phenyl- or p-tolyl-hydrazine-N-sulphonate is reacted with urea to give phenylor p-semicarbazide and phenylsemicarbazide is also obtained by using sodium isocyanate instead of urea; (2) the reaction liquor from the sodium sulphide reduction of benzene- or p-toluene-diazonium chloride gives similar results to (1).

Title: Improvements in dynamo electric generators
IPC: H02K23/02
Filed: 1952-05-02
Abstract: 698,655. Exciting D.C. generators. MACFARLANE, J. W., and MACFARLANE, W. I. May 2, 1952, No. 11117/52. Class 35. In a cross-flux amplifying generator having a short-span armature wind. ing, the normal excitation of the machine is done by main pole field coils ener. gized by a function of the generator output so that substantially no constant excitation current flows in the short-circuited quadrature axis, but only that required for control purposes. The machine is very similar to that described in Specification 566,168 except that in that machine the con. trol windings 10, 11 are arranged, when a continuous output is required, to be sufficiently out of balance to produce a continuous current in the short-circuited axis Q-Q which, in turn excites the main axis M-M to produce the required output at the main brushes X1, X2. In the present case the windings 10, 11 are mutually balanced in the absence of any signal and the load of continuous excitation is taken off the quadrature axis by the use of a selfexciting winding 12 in parallel or, as shown, in series with the continuous load terminals. The speed of reaction may be increased by the use of a transformer coupling from the main to the quadrature axis or by connecting a quadrature axis field winding in the short-circuit lead 7.
