Title: The manufacture of wetting agents
IPC: D06M13/256
Filed: 1937-07-14
Abstract: Wetting-agents are manufactured by reacting organic sulphonic acids or acid sulphuric esters having wetting power per se and containing either an aliphatic radicle containing at least 12 carbon atoms or an aromatic radicle substituted by aliphatic side chains containing at least 3 carbon atoms, or their salts, with salts of quaternary ammonium bases having attached to the pentavalent nitrogen atom, either directly or through a bridge consisting of an ether, ester or carboxylic acid amide group, a straight or branched chain aliphatic or cycloaliphatic radicle of 5 to 11 carbon atoms or an araliphatic radicle containing either a single aliphatic residue of 5 to 11 carbon atoms or two or more aliphatic residues having a total of 5 to 11 carbon atoms, the other radicles attached to the pentavalent nitrogen atom being either short aliphatic or heterocyclic residues. Suitable organic sulphonic acids and acid sulphuric esters are alkylated aromatic sulphonic acids and sulphonation products of unsaturated fatty acids or hydroxy fatty acids or preferably of their derivatives in which the carboxylic acid group is protected by esterification or amidation.  In examples: (1) a sulphonation product of oleic acid diethylamide is reacted with the ammonium salt prepared by reacting trimethylamine with 2 : 4-diisopropylbenzyl chloride; similar products are obtained if in the preparation of the ammonium salt the diisopropylbenzyl chloride is replaced by triisopropylbenzyl chloride, or the trimethylamine by pyridine or methylpiperidine; (2) the sodium salt of the sulphuric ester of hydroxystearic acid (obtained by sulphonating oleic acid) is mixed in aqueous solution with an ammonium salt obtained by reacting benzenesulphochloride and an excess of trimethylamine with n-octanol; (3) sulphonated ricinoleic acid butyl ester is reacted with an ammonium salt obtained by condensing chloracetic acid isoheptyl ester with trimethylamine; (4) the sodium salt of the dibutylated naphthalene-sulphonic acid prepared as described in example 1 of Specification 246,817, [Class 2 (iii)], is warmed with isoheptyltrimethylammonium methosulphate (obtained by peralkylating isoheptylamine with dimethyl sulphate). Samples have been furnished under Sect. 2 (5) of products obtained by the interaction of the following compounds: (I) the sodium salt of dibutylated naphthalenesulphonic acid (as in (4) above), and cyclohexyltrimethylammonium methosulphate (obtained by peralkylating cyclohexylamine with dimethyl sulphate); (II) the sulphuric ester from oleic acid dimethylamide, and the ammonium salt obtained by reacting octyl chloromethyl ether with trimethylamine; (III) the sodium salt of the sulphuric ester of hydroxystearic acid (as in (2) above), and an ammonium salt obtained by reacting chloracetylisoheptylamine with trimethylamine.

Abstract: 1,178,645. Ultrasonic cleaning apparatus. BRANSON INSTRUMENTS, Inc. 26 April, 1968 [9 May, 1967], No. 19847/68. Heading A4F. Ultrasonic cleaning apparatus, comprising for example a transducer arranged to produce ultrasonic vibrations in cleaning liquid in a tank in which articles to be cleaned are immersed, includes an oscillating electric circuit which energizes a transducer at a frequency higher than the antiresonance frequency of the transducer. In the transistor oscillator circuit illustrated, current pulses of mean value Io pass to the transducer 14 via the primary coil 24aa of a transformer 24, whilst current pulses of greater mean value Ii pass to a condenser 22 via the transformer primary coil 24a, whereby current pulses are produced in the transformer secondary coil 24b of mean value If proportional to the difference between Ii and Io. The latter current pulses pass in a feedback circuit to the base of the transistor 30 to initiate the driving pulses of the oscillator in a transformer primary coil 28a. The circuit is such that in the event of an increase in the current value Io due to a resonance condition at the transducer 14, the reduction in the difference between Io and Ii reduces If to increase the frequency of the oscillation to a value above that causing resonance at the transducer 14.

Title: Improvements in or relating to controlling systems for lifts
IPC: B66B1/16
Filed: 1936-04-14
Abstract: 458,988. Lifts. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CHUBB, A. A., c /o General Electric Co., Ltd., Stoke, Coventry. April 14, 1936, No. 19917/35. [Class 78 (ii)] In a lift-controlling system wherein the destination of the car is under the control of floor switches and car switches, the floor switches are rendered ineffective for call storage during a predetermined period after each closure of a lift gate by an electromagnetcondenser combination. The lift is controlled by a set of floor push buttons lp1 .. lp4 and a set of car buttons cp1 .. cp4. When a push is operated a corresponding storage relay A .. D is operated and relays R, H are operated in series. The operated storage relay opens a short-circuit across relay DR and extending over wiper W1 of a stepping switch which occupies a position corresponding to that of the lift. Relay DR prepares the circuit of a second winding of the relay DR and in conjunction with relay R energizes the " up " or "down" relays UD, DD which starts the driving motor ST in the appropriate direction. An indicator relay Z is operated by the passage of the lift past points intermediate between the floors and the switch W is stepped until, when the lift passes the intermediate point prior to the selected destination, relay PS is operated over wiper W1. Relay H operated in series with R prevents, at contact h1, other landing pushes from storing calls. Operation of relay PS prepares a short-circuit for R and connects a condenser CA into circuit. When the lift arrives within a short distance of the selected floor an inductor relay S is operated and R is short-circuited to stop the motor, open circuit all push button circuits to prevent further storage of calls, and open-circuit relay PS which, however, holds up under the control of the condenser CA for a time sufficient to enable a passenger to open the lift gate. Opening the gate releases relay G which prevents restarting of the lift and charges a condenser CB. When the gate is closed the car buttons are given priority over the floor buttons for a period determined by the condenser CB which discharges slowly through relay H to prevent storage of calls from the floor buttons.

Two endless side chains 11 running over sprockets 12, 15 and over adjustable jocket pinions 14 carry a plurality of clips 10 which engage the rod 7 at the top of the lowermost of the panels stacked on the supports 8 and lift the panel out of view at the window 3. The clips 10 convey the rod 7 past the pinions 14 and the panel trails over a roller 13 on which the sprockets 12 are fixed. When the bottom rod 7 of the moving panel is free of the roller 13 the panel drops by gravity into an inverted and back-to-front position, its trailing rod 7 falling on top of the supports 8, and its leading rod being directed by guides 17. The roller 13 is covered with cloth to provide sufficient friction to move the panel after the leading rod 7 has dropped out of its clips 10. Motive power is applied to one of the chains 11 and is conveyed to the other chain 11 and its associated wheels through the roller 13. The supports 8 may each be formed of an inclined and a horizontal portion and between these parts a reciprocating spring-cushioned member is mounted to pack the rods 7 tightly against one another. The member is reciprocated by an eccentric mounted on the stub shaft of the pinion 14. The screens may be aligned by projections on the chains 11 co-operating with pivoted levers carrying cushions pushing the rods 7 into place. The panels may be made wholly or in part of flexible and transparent material in envelope form to hold articles. In modifications the chains 11 are replaced by a single central chain, belt, band, &c., which may be endless and move uniformly or be a length which is reciprocated.

Abstract: 1331815 Bi-stable circuit INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [22 Jan 1970] 20078/71 Heading H3T [Also in Division G4] A bi-stable circuit SP1 comprises two coupled double-emitter like conductivity type transistors T1, T4 each having an emitter connected to an emitter of a respective control transistor T2, T3 and to a bit line VB1, VB2, each control transistor having a potential on its base which can be varied to write data bits into the circuit. The circuit is " read " by raising the voltage at the junction of the collector load resistors Z so that the emitter potential of the on transistor, say T1, rises and therefore causes a decrease in collector current of the emitter-coupled transistor T2 which can be measured by a sense amplifier with inputs connected between termi. nals 19. When " writing " a logical 0 into the circuit, assuming a logical 1 is stored, the potential at the base of transistor T3 is held constant and the potential at the base of transistor T2 is lowered. Lowering of the potential at the junction of the two load resistors Z then causes the state of the circuit to be changed. The bit line VB2 at the emitter of transistor T3 is restored via this transistor when the potential at the said junction is lowered. Each control transistor T2, T3 is operated by a driver circuit T5-T9 in response to signals applied to the bases of transistors T8, T9 and an enabling signal VRN to current source transistors T5, T6. The appropriate circuit SP1 is selected by a word decoding network 31 and a phase-splitting network 32. The phase splitting network causes a current-limiting resistor in series with the two load resistors Z to be by-passed by a collectoremitter path of a transistor (TC, Fig. 1, not shown) to raise the potential at said junction when reading from or writing into the circuit. Bit decoding network 33 selects via phase splitter 34, the corresponding drive circuit T5-T9.
