Abstract: 131,178. Roch, C. M. J., and Mouchel & Partners, L. G. Aug. 29, 1918. Decks. - Reinforced - concrete floors, decks, &c. are formed of. beams and slabs ' without the use of temporary shuttering by means of previously cast beams g, Fig. 1, which are provided with tensile reinforcement and stirrups, but are otherwise unfinished and are temporarily strengthened by wire rope or chain ties d and one or more struts c. The ties d are connected to pins p inserted in holes in the beams, and the struts c are secured by wedges a. Notches r may be formed in the beams to receive transverse joists, Fig. 7, which are similarly strengthened by ties and struts and have their bars m projecting at the ends into the notches r. The ends of the joists are supported either on wooden or other blocks b secured by clamps p<1>, or on corbels e, Fig. 12, formed on the main beams. Concrete slabs q, Fig. 8, rest at their ends on the joists, and the spaces t between their ends receive the stirrups l; the edges of the slabs may rest either on blocks b clamped to the main beams or joists, or on continuous or nearly continuous ledges v. The joints are then grouted, and a top layer f of concrete may be applied over the slabs and joints. The main beams may rest on brackets or corbels formed on concrete pillars, and the reinforcements of the beams and joists and slabs may be interconnected in the grouting of the junctions. The transverse joists may be omitted.

Title: Improvements in or relating to electric relay devices
IPC: H03K17/54
Filed: 1940-09-10
Abstract: 542,821. Electromagnetic relays. SANGAMO WESTON, Ltd. Sept. 10, 1940, No. 14056. Convention date, April 8. [Class 38 (v)] [Also in Group XL] The moving and fixed contacts 2, 3, 4 of an instrument-type relay are made highly flexible so as to be in a state of continuous vibration and are associated with a thermionic valve 5 so as to control the anode circuit. in the form shown, the valve 5 is a grid-controlled gas tetrode. The secondary of a transformer 9 tends ing alternate half-cycles but the potential of the to send current through the anode circuit durgrid G, normally prevents the current flowing. When the contact 2, which may be responsive to temperature, pressure, humidity, illumination or other quantity, engages either of the contacts 3, 4, the potential of the grid G, becomes substantially that of the cathode K and current passes to an alarm or control element 12. In a modification condensers are added to provide a time delay. In another modification, the anode ,circuit normally carries current and engagement of the contact 3 or 4 blocks it. In another modification, the contacts 3, 4 control the grids of two separate valves, the anode circuits of which include the two primary windings of two transformers which feed the field windings of a reversible impulse motor of the double field, double rotor type. The motor is thus driven one way or the other according to which contact is engaged, and may produce conditions tending to move the movable contact 2 back again. The motor is arranged to reach full speed within one half cycle of A.C. so that its speed depends upon the integrated time of closure of the contacts and will increase as the contact 2 tends to move more from its central position.

[Also in Division H3] Selecting matrix, connecting control lines in a super-conductive store to a pulse source, has a cryotron having three equal ranking control conductors provided at each intersection of the matrix with the first control conductors of all the cryotrons in each row being connected in a series chain, the second control conductors of all the cryotrons in each column being connected together in a series chain and the third control conductors of all the cryotrons being connected together in a series chain, wherein one terminal of the gate of each cryotron is connected together with the corresponding terminal of the gates of a plurality of other cryotrons to form at least one group, the other terminal of the gates being adapted for connection to respective control lines of a superconductive store. The cryotron matrix has the first and second control conductors connected in series chains as shown in Fig. 1b The third control conductors (not shown) are connected in a series chain coupling all cryotrons and this conductor carries a setting current more than twice as large as the critical current so that all cryotrons are held in their normal conductive state. Control currents Is I z , both greater than the critical current are combined to cancel out the effect of the setting current at the cryotron situated at the junction of the selected row and column conductors. The now super-conductive cryotron passes current I a  to the appropriate control wire of the memory. Each row wire connected to the pulse terminal E may include a decoupling two-controlwire cryotron r as shown in Fig. 2 or the said cryotron may not be present. Their presence produces a smaller time constant for the circuit.

Abstract: Esters or amides of the sulphonic or carboxylic acids of the benzene or naphthalene series are made, in the naphthalene series, by reacting the chlorides of 2-diazo-naphthol-(1)- or 1-diazo-naphthol-(2)-sulphonic or carboxylic acids with aromatic hydroxyl compounds such as phenols, naphthols, 1 - nitro - 2 - naphthol, N - benzoyl - p-aminophenol, N-acetyl- or N-benzoyl-1 : 5- or -2 : 8-aminonaphthol, hydroxy-phenanthrenes, 2-hydroxychrysene, hydroxynaphthimidazoles, 4 : 41 - dihydroxydiphenylsulphone - b  : b - bis - (4-hydroxyphenyl)-propane, or 1- or 2-hydroxyanthroquinone or with primary or secondary amines or diamines such as N-methylaniline, N-ethylnaphthylamine, 2 : 4-dichloraniline, p-phenetidine, p - aminodiphenylamine, aminofluorene, aminodiphenylene oxide, dodecylamine, p-phenylene diamine, diamino-diphenylmethane or naphthylene diamine in aqueous alkaline solution.  Thus (example 1) 2 mol. of 2 - diazo - naphthol - (1) - 5 - sulphochloride and 1 mol. of 4 : 41-dihydroxy-diphenyl-sulphone are heated in aqueous dioxane solution of sodium carbonate and cooled to separate the condensation product which is then washed with water and recrystallized from dioxane.  In example 9 the same sulphochloride is reacted similarly with metol and with 7-hydroxynaphthalene-1-biguanide.  Example 10 describes the production of 2-diazonaphthol-(1)-4 : 7-di-(sulphon-N-ethylanilide) by reduction of the azo dye produced from diazotized aniline and 1-hydroxy-naphthalene - 4 : 7 - di - (sulphon - N - ethylanilide) (for preparation see Group IV (c)) with hydrosulphite and caustic soda and diazotization of the resulting 2 - amino - 1 - hydroxynaphthalene - 4 : 7 - di - (sulphon - N - ethylanilide) Of the benzene derivatives example 8 describes the production of 6-methyl-benzoquinone-(1 : 2)-diazide - (2) - 4 - sulphon - N : N - diphenylamide by conversion of 6-methyl-2-amino-1-hydroxybenzene-4-sulphonic acid into 6-methylbenzoxazolone - 5 - sulphonic acid and this into the corresponding sulphochloride, which latter is heated with excess of diphenylamine and the resulting amide is hydrolysed to produce 6 - methyl - 2 - aminophenol - 4 - sulphon - N : N-diphenylamide. Diazotization then produces the diazide.  Specifications 401,898, 418,011 and 699,412 are referred to.ALSO:Diazotized aniline is coupled in aqueous dioxane with 1-hydroxy-naphthalene-4 : 7-di-(sulphon-N-ethylanilide), which latter is made by condensing 1-naphthol-4:7-disulphonic acid with benzene sulphochloride in alkaline solution to make the sodium salt of the 1-benzene-sulphonic acid ester of 1-hydroxy-naphthalene - 4 : 7 - disulphonic acid, treating this with phosphorus pentachloride to produce the disulphochloride which is converted with monoethylaniline to the corresponding disulphon-N-ethylanilide.  Hydrolysis of the ester produces the hydroxy compound.  Specifications 401,898, 418,011 and 699,412, [Group IV(b)], are referred to.
