Title: Detergent compositions
IPC: C11D17/00
Filed: 1963-05-01
Abstract: Liquid detergent compositions comprise, by weight, (a) 10 to 40% of a mixture of a water-soluble alkyl mononuclear aryl sulphonate detergent having an average of 8 to 15 carbon atoms in the alkyl group and a multi-branched alkyl polyoxyethylene ethanol having 8 to 18 carbon atoms in the alkyl group and an average of 5 to 30 ethylene oxide units, the ratio of the alkyl aryl sulphonate to the alkyl polyethoxamer being from 10:1 to 1:4 by weight with at least 3% of each material present in the composition, (b) 5 to 20% of a water-soluble alkanolamine having 2 or 3 carbon atoms in the or each alkanol group, and (c) 1 to 15% of a water-soluble hydrotropic sulphonate, the balance being wholly or predominantly water, the compositions having an alkaline pH and being in the form of substantially homogeneous pourable liquids at room temperature. Specified alkyl groups in the alkyl mononuclear aryl sulphonates used are nonyl, dodecyl, pentadecyl, n-decyl, ceryl, and tridecyl groups. The sulphonates are used as sodium, potassium, ammonium, lower alkylolamine salts and alkaline earth metal salts, e.g. magnesium, have at least 85% purity and may contain sodium or potassium sulphate.  Examples of alcohols used to obtain the alkyl polyoxyethylene ethanols are 2,4,5,5,7-pentamethyl-1-octanol; 2,3,5,7-tetramethyl-1-nonanol; 3,5-di-ethyl-1-octanol and 2,4,6,8-tetramethyl-1-nonanol. Preferably multi-branched tri-decyl polyoxyethylene ethanol is used.  The hydrotropic sulphonates used are alkali metal organic sulphonated salts having a lower alkyl group up to 6 carbon atoms, e.g. sodium or potassium xylene, toluene, ethylbenzene or isopropyl benzene sulphonates, and isomers thereof. Alternatively, lower alkyl sulphate salts having 5 or 6 carbon atoms may be used. Mono, di- or tri-ethanolamine and isopropanolamine are exemplary of the alkanolamines.  The pH of the composition is at least 9 and may be adjusted by adding alkali, e.g. NaOH.  Soil suspending materials, e.g. carboxy lower alkyl cellulose, cellulose sulphate, polyvinyl alcohols, polyvinyl pyrrolidone and castor wax may be incorporated into the composition.  Preferably the composition also contains 1 to 10% of an alkylolamide, e.g. those having 8 to 18 carbon atoms in the acyl radical, each alkylol group having one to three carbon atoms, and include lauric, cupric, myristic and coconut di-ethanolamides, monoethanolamides and isopropanolamides which may be condensed with one to two moles of ethylene oxide. Other ingredients specified are perfumes; colouring materials; corrosion or tarnish inhibitors; sequestering agents; germicides; softening or bleaching agents; fluorescent dyes; alcohols, (e.g. fatty alcohols, ethanol), and urea.

Title: Circuit for sequentially flashing photoflash lamps
Inventor: WATROUS DONALD LELAND
IPC: H05B37/02
Filed: 1970-04-10
Abstract: 1,262,623. Control systems for photoflash arrays. GENERAL ELECTRIC CO. 10 April, 1970 [29 April, 1969], No. 17259/70. Heading H2H. A circuit arrangement for flashing in sequence an array of replaceable photoflash lamps comprises a plurality of circuits connected across a pair of supply lines in parallel and sequencing control means coupled with the lamp circuits so as to flash the lamps in sequence from the first to the last together with means for inhibiting the flashing of each lamp until the preceding lamp has been flashed. An array of four flash lamps 11a-11d is connected across D.C. supply lines 13, 14 each time a camera shutter operated switch 17 is closed. Each lamp has a semiconductor device-such as thyristors 15a-15d -connected in series therewith and the lines 13, 14 are energized each time a switch 17, associated with the camera shutter release 19, is closed. The first closure of the switch 17 causes thyristor 15a to fire whereupon the lamp 11a is flashed. The current passing through the lamp 11a upon flashing creates a voltage drop across resistor 16, which turns on a thyristor 25 and thence a transistor 28 thus establishing a current path between the lines 13, 14 through resistor 24. No current thus flows through the Zener diode 23 and the bus-bar 21 remains de-energized. After a short time-8 milliseconds-the lamp 11a burns out and the thyristor 15a turns off. Upon the next operating of the switch 17 current flows through a circuit comprising resistors 16, 24, Zener diode 23, the emitter-base path of a transistor 20b, a resistor 22b and the gatecathode junction of thyristor 15a. Thyristor 15b is thus gated on to flash lamp 11b and the current flowing therethrough again develops a voltage drop across resistor 16 to turn on thyristor 25 and transistor 28 to de-energize bus-bar 21 thus turning off thyristor 15a. Thyristor 15b turns off when the lamp 11b burns out and the circuit remains quiescent until the switch 17 is again closed whereupon the operation repeats for the third lamp 11c and so on. Other embodiments are shown wherein open-circuited lamps are automatically by-passed, so called air lamps are burned out and flashed, short-circuited lamps may be visually indicated to enable the array to be replaced. In some embodiments current or light sensing operates the lockout transistor 28 or the lamp sequencing initiated by an externally generated pulse. Furthermore modifications may be made so that the sequencing of the lamp flashing may be interrupted at any selected time, the circuit may be de-energized after a predetermined interval or the start of the lamp flashing sequence delayed after the closing of the camera shutter.

Title: Improved means for attaching engine cylinders to crankcases
IPC: F02F1/04
Filed: 1921-06-27
Abstract: 182,678. Armstrong Siddeley Motors, Ltd., and Viale, S. M. June 27, 1921. Locking nuts.-Engine cylinders are held down by means of a nut A, held in position inside the crank case B by the ring E and spring ring E2 and rotated from outside the crankcase by the pinion F2 and shaft F which is locked by the plate H2, Fig. 2., engaging with the dogs F5. The plate H2 can be fixed in three angular positions, and since there are eight dogs F5, a position of the plate H2 can always be found at which the bar H very nearly fits between the dogs. Instead of the pinion P2 remaining permanently in the crank case, a removable tool may be used to tighten up the nut A, and a locking device, cut with teeth as shown in Fig. 5, inserted to take its place. The four sets of teeth shown, occupy different positions relatively to the axes XX, YY so that one of the sets will always coincide very nearly with the teeth on the nut when the locking-device is inserted. The said locking device is itself locked by expanding the outer split end thereof by means of a cone. The shaft F may be parallel with the cylinder axis in which case the upper end may be splined to take a locking-ring by which it may be locked in many positions in a manner similar to that previously described.

Title: Improvements in or relating to the oxidation of aliphatic carboxylic acids to peracids
Inventor: HAWKINSON ALFRED THEODORE
IPC: C07C409/24
Filed: 1954-12-02
Abstract: A method of preparing an aliphatic peracid comprises oxidizing with hydrogen peroxide an aliphatic carboxylic acid in the presence of a nuclear sulphonated aromatic hydrocarbon cation-exchange resin in its hydrogen form.  Suitable resins are sulphonated polymers of polyvinyl aryl compounds, such as divinyl benzene and the sulphonated copolymers of such polyvinyl aryl compounds with monovinyl aryl compounds such as styrene described in Specification 571,029, [Group IV].  Preferred are aliphatic acids of 1 to 4 carbon atoms.  When a liquid, the acid is usually employed in excess as the reaction medium.  Reaction temperatures of 15 DEG  to 70 DEG  C., preferably 25 DEG  to 50 DEG  C. are suitable.  The hydrogen peroxide is of at least 25 per cent and is preferably of 35 per cent strength.  In Examples (1) and (2), glacial acetic acid is oxidized to peracetic acid by treatment with 50 per cent aqueous hydrogen peroxide at 40-45 DEG  C. in the presence of a cation exchange resin (in the hydrogen form) obtained by sulphonating a copolymer of styrene and about 8 per cent divinyl benzene, the resin containing about one -SO3H group per benzene ring; (3) perpropionic acid is similarly prepared from propionic acid.

Title: Improvements in closures for bottles and other containers
IPC: B65D39/12
Filed: 1926-07-14
Abstract: 280,261. Carpmael, R. H. July 14, 1926. Capsule and like closures ; stoppers hinged at one side; retaining devices in receptacle neck above closure ; retaining devices below closure ; closures completed by outstanding packing rings. -A closure for bottles and other containers comprises a resilient disc a formed with peripheral fingers b adapted to engage the internal wall of the container and a central bulged portion d adapted to be moved from one side of the horizontal to the other to move the fingers into engagement with the mouth of the container. The closure may be operated by a knob &c. e secured to the bulged portion d. The ends of the fingers may be flanged to engage an undercut groove k, Fig. 4, in the wall of the container and a flanged outer cap g, secured to the disc, may engage the rim of the container. When the closure is to be used repeatedly, it may be hardened' or toughened in either its release or secure position so that it will return to that position, means being provided for locking it in the displaced position or in both positions. The cap g, Fig. 7, is secured to the disc a by the shank f of the knob e, the shank passing through an aperture in the cap and being provided with a feather m which normally rests in a groove l in the cap but which is removed therefrom when the knob is pulled upwards to release the cap and may be secured by rotating the knob. In other modifications, the groove is L-shaped to permit the closure to be locked in the secure position and the top of the cap is formed with cam portions along which the feather slides so that rotation of the knob operates the closure. The disc may be secured directly to the cap, a boss on the disc or cap ensuring the. necessary distance between them. The fingers may be used to expand a rubber ring against the wall of the container. In another form, upstanding projections i<1>, Fig. 17, on the inner side of the ledge in the container mouth prevent withdrawal of the flanged fingers b from the undercut groove j when the disc is rotated slightly after being inserted in the container mouth. A construction especially suitable for a cartridge case is shown in Fig. 22, the disc having secured to its underside a sealing-member g<1> which is pressed on a packing in the container mouth. As applied to the cover of an oil cup, the cap g, Fig. 15, is formed with projections x which engage grooves in the cup to exclude dust. The fingers may be replaced by one or more leaf springs.

IPC: B28B7/18
Filed: 1920-06-29
Abstract: 169,781. Crozier, A. O. June 29, 1920. Delivery; stream-cutting machines; moulding- machines.-Hollow cementitious articles such as bricks, building blocks and tiles, drain and sewer pipes, &c., are made by providing in an upright shaft or container having vertical cores a column of cement mixture preferably of such a height as to effect by its own weight a compacting of the lower part of the column, which is cut off and removed. Fig. 1 shows a machine in which the cement fills the shaft 13 having cores 33. The lower end of the shaft 13 is closed by one of a series of pallets 16. The cores 33 are raised by means of a rod 28 and cam 32 on the shaft 22 and, in rising, lift the rod 42 by means of tappets 45, 46 and operate the severing-knives 37, Figs. 1 and 5, by means of levers 41. The severed portion is then lowered on its pallet 16 by means of a table 17, rods 18, cams 24, and rollers 23, and is removed by the endless chain 63, which also brings a fresh pallet into position. The table 17 then rises, the knives 37 are withdrawn, and the cores 33 together with the column of cement drop, the impact facilitating the compacting of the lower portion of the concrete. The cores are preferably heated by means of steam or hot-water pipes 34, 35. The cores may be stationary and the shaft vertically movable, or both the cores and shaft may be movable. Figs. 14 and 18 show a hand-operated machine in which cores 73 within the upright shaft 70 are raised by levers 77, and the lower portion of the column of cement is severed by taut wires 39 which are operated by a frame 90 and given a sideways sawing movement. The severed lower portion resting on a pallet 80 is lowered by means of the table 81. wedge 82, and lever 87, and is removed through the doors 107. If the block is to be subdivided, cutting- wires are attached to the rods 99, which are raised with the cores.
