Title: Fully adjustable non-slip, jack safety prop
Inventor: BAKER GORDON THOMAS
IPC: B66F3/36
Filed: 1969-01-14
Abstract: 1,236,193. Jack safety props. G. T. BAKER. 21 Nov., 1969 [14 Jan., 1969], No. 2244/69. Heading B8J. A safety prop for a mobile hydraulic lever jack 13 is adapted to fit between lifting pad pivot pin 18 and trolley axle 12. The prop comprises three parts: a tubular lower support member 1 with a cradle 11 to fit the axle 12 ; a tubular centre support member 2, sliding rotatably in the member 1 and having a nut 15 secured to its upper end; and an upper support member 3, which is a threaded bar 16 having a cradle 17 to fit the pin 18 and carrying a locknut 19. In use, the members 1, 3 are relatively displaced by turning the member 2. Means may be provided, Figs. 2, 3 (not shown), to prevent the members 2, 3 from being separated in transit or at all. The cradles 11, 17 may surround the respective axle 12 or pin 18, thus attaching the associated member 1, 3 to the jack.

Abstract: 1,189,263. Klystrons. ENGLISH ELECTRIC VALVE CO. Ltd. 9 Oct., 1968 [16 Jan., 1968], No. 2247/68. Heading H1D. Compensation for the variation with temperature of the resonant frequency of a klystron cavity, due to change both in the cavity volume and in the gap 6 between the drift tubes 5, is provided by a capacitative element disposed in the cavity in the neighbourhood of the gap, and so constructed or supported as to vary its position in relation to the gap with variation of temperature. As shown, the capacitative element 7, is constituted by a bi-metallic plate disposed in the cavity outside the ceramic envelope 4 of the tube and supported from the cavity wall by a bar 8 of material of high thermal conductivity; the plate is arranged to bend away from the gap 6 with increase of temperature. In an alternative arrangement, the element is a copper plate which is caused to move, with a change of temperature, by a separate bi-metallic element.

Abstract: 510,310. Making emulsions. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 25, 1938, No. 2250/39. Divided out of 510,318. [Class 1 (i)] [Also in Group IV] Secondary amines containing at least two aliphatic hydrocarbon radicles each containing at least three carbon atoms and together containing at least eight carbon atoms attached to nitrogen are treated with phosgene and the condensation products reacted with an organic aminocarboxylic, aminosulphonic or hydroxysulphonic acid, an amino sulphuric acid ester or with an organic aminopolyhydroxy compound. The secondary amines may be obtained from the following carboxylic acids : fatty acids such as isobutyric, isovalerianic, caprylic, palmitic, oleic, ricinoleic, and oc-ethylhexylic acid, carboxylic acid mixtures obtained by the oxidation of paraffin or by treating the mixtures obtained by the catalytic hydrogenation of carbon 'oxides, with alkali, carboxylic acids obtained by treating carbon mono- or dioxide with steam in the presence of an olefine and hydrogen and by saponifying nitriles resulting from the treatment of a halogenated hydrocarbon with potassium cyanide. Amines may also be prepared from halogenated hydrocarbons and ammonia or amines. The products are stated to be useful as emulsifying agents and may be used in association with soap, mucilage, glue, soluble cellulose derivatives, starch, bentonite, saponine, solvents such as butanol or xylenylglycol, sodium carbonate, Glauber's salt, sodium pyrophosphate, trisodiumphosphate, sodium metaphosphate, sodium perborate and sodium hypochlorite. In examples : (1) di-isoheptylamine is reacted with phosgene in the presence of chlorbenzene saturated with hydrochloric acid and the resulting di-isoheptylcarbamic acid chloride condensed with sodium methyltaurine. (2) di-(#-ethylhexyl) amine is reacted with phosgene and the resulting carbamic acid chloride condensed with sodium butyltaurine; the latter may be replaced by isobutyltaurine, #-ethylhexyltaurine, sulphanilic acid, metanilic acid or ethanolamine sulphuric ester. (3) n-butyltetradecylcarbamic acid chloride is condensed with sodium sarcosine. (4) a mixture of carbamic acid chlorides prepared from secondary amines obtained from carboxylic acids resulting from the oxidation of paraffin is condensed with metanilic acid. The following components are mentioned: methylglucamine, hydroxyethanesulphonic acid and albumin decomposition products.

Title: Input/output equipment
IPC: G06F3/09
Filed: 1958-01-23
Abstract: 876,180. Digital data-storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 23, 1958 [Jan. 24, 1957], No. 2299/58. Class 106 (1). A data storage medium comprises a plurality of sectors each of which is allocated a respective input/output device and is divided into a number of subdivisions in each of which a data character may be stored, each subdivision being identified by a number, and in apparatus for transferring data between the input/output devices and the storage medium, each sector is allotted recurring time periods in which data transfer may take place, means is provided for determining and storing, for each sector, the number of the subdivision to or from which data transfer is to take place in the next recurring time period, a counter indicates the number identifying a subdivision available for data transfer at any instant, and means is responsive to a comparison of successive stored numbers with the output of the counter to transfer one or more data characters between respective ones of the input/output devices and the appropriate subdivisions. In one embodiment described the subdivision number store is a shift register 11 in which each position corresponds to a sector of a magnetic storage drum, each number being stored in the form of five binary bits in parallel. As each sector of the storage drum moves into data transfer position a pulse is applied to open gates 19 and a number stored in flip-flops 18 is transferred to flip-flops 14. A delayed sector pulse shifts the first number stored in register 11 into flip-flops 18. Counter 16 is reset at the end of each sector period and counts the subdivisions as they enter the data transfer position. When the output of counter 16 corresponds to the number n stored in flip-flops 14 a pulse is delivered by coincidence gates 21, and is fed over a path introducing a delay to open gates 26 when the output of counter 16 is n+k, k characters being transferred for each sector in one revolution of the drum. The number n+k is thus transferred to flip-flops 31 ready to be entered in register 11. Block 40 controls the writing of data characters into the drum, and in the case illustrated k is three and each data character is a five-bit number stored in sets of flip-flops 44, 45, 46 prior to their transfer to the drum. An output is obtained on lines 61, 62, 63 if a number is stored in the respective set 46, 45, 44, line 62 opening gate 43. The pulse from gates 21, signifying that the correct subdivision is in position for data transfer, triggers flip-flop 41, 42 which then produces a pulse train to open gates 51, 52, 53 and shift the data characters into successive subdivisions. When the last number has passed out of set 45, gate 43 is closed and flip-flop 41, 42 produces only one more pulse to transfer the last character from set 46. A similar block 40 is provided to read data from the drum to an output device. In another embodiment, Fig. 2 (not shown), the output n of flip-flops 14 is fed direct to an adder where k is added, so that the number n+k is again entered in register 11.
