Title: Reduction of viscosity of water-soluble non-ionic cellulose ethers
Inventor: GILL JOHN ERNEST
IPC: C08B11/20
Filed: 1962-02-16
Abstract: The viscosities of water-soluble non-ionic cellulose ethers is reduced by treating the cellulose ether, without substantial dissolution, with an aqueous solution of hydrogen peroxide, the duration and temperature of the treatment being controlled in accordance with the amount of reduction in viscosity desired.  The cellulose ether may be suspended as a slurry in a liquid in which it is insoluble at the treatment temperature and the aqueous solution of hydrogen peroxide added to the slurry.  Alternatively, the cellulose ether, either dry or moistened with a liquid in which it is insoluble at the treatment temperature, may be sprayed evenly with a proportion of an aqueous solution of hydrogen peroxide insufficient to dissolve the ether and may thereafter be subjected to sufficient heat treatment to effect the required viscosity reduction.  The cellulose ether may be soluble both in hot water and in water at ordinary temperatures. In the slurry method the cellulose ether may be suspended in an aqueous alcohol of sufficient alcohol concentration to prevent gelling of the ether. If the ether is soluble in water at room temperature and insoluble in hot water, it may be suspended for treatment in water maintained at a temperature above the gel point. In this case the ether may be methyl, ethyl, ethyl methyl-, hydroxyethyl methyl-, hydroxyethyl ethyl, hydroxypropyl methyl, or hydroxypropyl ethyl-cellulose. The treatment may be effected at a pH of between 5 and 9. The viscosity of the cellulose ether may be determined in a 2% aqueous solution of the ether at 20 DEG C., by the method of BSS 188 (1957). If ethyl alcohol is present with the mass of ether being treated the treatment temperature must be sufficiently high to evaporate off the alcohol before the peroxide becomes effective.  The process is applicable to ethers which, although insoluble in neutral aqueous solutions, are soluble in alkaline aqueous solutions.

Title: Improvements relating to card cutting machines and to loom jacquards and dobbies
IPC: D03C17/00
Filed: 1936-02-15
Abstract: 469,654. Jacquards; cutting cards. JONES, N. Feb. 15, 1936, No..6086/35. [Class 142 (i)] Relates to devices wherein a pattern or design is scanned by a point of light and the reflected light controls electric circuits actuating electromagnets for operating the needles of a loom Jacquard or dobbie or of a Jacquard used in a punching machine. The design &c. is divided into parts mounted on respective rollers d, d<1>, d<2> on a sliding carrier D<1>, which is reciprocated by an oscillating arm E on a stud carrying a wheel oscillated by lever mechanism controlled by cams. The design &c. is thus traversed line by line in front of light projectors F, the rollers being intermittently rotated after each traverse by pawls engaging ratchet wheels therein and carried by rods d<6> operated by levers d<5> controlled by stops d<4>. The light reflected from the design &c. operates photo-electric cells in circuit with amplifiers H. These each control a relay circuit connected to the respective three contact points j<1> of an oscillating contact moving over stationary contacts j, which are electrically connected to wiper contacts k<3> moving over plug contacts K<2>. The contacts k<3> are carried by rods on a frame, which is vertically reciprocated by cam-controlled mechanism and the contacts K<2> are connected to electromagnets c<2> on a sliding frame C. At each stroke of the carrier D<1> selected electromagnets c<2> are energized and corresponding pivoted catches operated by their armatures are raised. Corresponding latches are thereby released and fall into position to engage, when the frame C moves to the left, cranked push needles a<1>, which operate corresponding jacquard needles a. These are shown as controlling a repeater card cutting devices, but they may be the needles of a loom jacquard and by connecting each contact K<2> to several electromagnets, several looms, each weaving the same pattern, may be simultaneously operated. The released latches are returned to operative position in a manner described and illustrated in Figs. 5 and 6 (not shown), and an automatic check can be made by wiring double sets of circuits and photo-electric cells working oppositely to the first sets of circuits, the wiring being such that the electromagnets will not operate unless the two sets of circuits synchronize.

Abstract: 1422707 Making sheet steel containers; cupping K M ENG AG 12 Feb 1973 [11 Feb 1972] 6834/73 Headings B3A and B3Q A method of making a sheet steel container from a deep drawn cup-shaped sheet steel blank comprises subjecting the cup-shaped blank to a series of forming steps, each comprising simultaneously deep-drawing and ironing the blank by forcing it through a single annular deepdrawing and ironing die with a punch member 32 within the blank. Blanks (2), Fig. 1 (not shown), are subjected to a series of deep-drawing operations in separate assemblies to form successively cup-shaped blanks (8a) to (8g), Figs. 2 to 8 (not shown), followed by piercing of the bottom of the cup-shaped blank, which is then necked, and the necked part curled. Alternatively the bottom of the blank may be domed inwardly, Fig. 17. A blank 8i is placed inside a stretch ring 13 and is supported on an ejector 16. Lubricant and/or coolant is supplied either through conduits 44 in a stripper member 45 or through conduits in a ring member 41. The latter conduits are directed at an angle α, which may lie between 0-90 degrees with reference to a punch member 14. Lubricant conduits 46 may also be provided in the stretch ring 16. The punch 14 has a central passage 18 for return of lubricant supplied to the interior of the blank. A number of stretch forming operations are performed, in which the cupshaped blank is formed to the required height, while its walls are reduced in thickness. The portion 20 of the blank, which does not pass through the stretch rings, is bent and trimmed to form a flange 29, Fig. 20. The blank is placed in a die member 30 and a resilient member 35 is located on a punch member 32 inside the blank. A pressure stamp 36 is driven downwardly to expand the member 35 radially outwardly thereby forming a smooth outer surface to the side wall. The deep-drawing and stretch forming operations are performed simultaneously on a plurality of blanks, each blank being passed through each working stage in succession. The piercing and curling of the necked part of the blank may take place after stretch forming. In an alternative method, the sheet steel blanks are cut in joined pairs which are separated and then the pairs deep drawn and stretch formed together. The deep-drawing operations may be performed in two stages, the direction of drawing being reversed for the second stage, Figs. 22, 23 (not shown).

Title: Device for Measuring Absolute Vibrations in Rotor-Stator Systems.

Filed: 1967-02-14
Abstract: 1,165,631. Measuring vibrations electrically. KHARKOVSKY FILIAL INSTITUTA AVTOMATIKI. Feb.14, 1967, No.7029/67. Heading GIN. Absolute vibrations of a body are measured by an inductor whose inductance or Q factor is varied by vibration of the body. The inductor is connected in a tuned circuit connected to amplitude modulate the output from an oscillator and is mounted by resilient spring means from a second body so as to be substantially stationary in an inertial frame of reference. As described, an inertial mass 2, Fig. 1, is supported by springs 3 in a cylindrical casting 1, 4, which may be filled with a viscous liquid, and which is fixed on the stator 10 of a stator, rotor system. Vibrations of the rotor 11 are detected by inductor L connected in series with capacitance C coupled to an oscillator (13, Fig. 2 not shown). The amplitude modulated signal from the series resonant circuit LC is converted by circuit 16 to a 1.f. signal indicative of the amplitude and frequency of vibration of the rotor 1 which is fed via resistor 17 and h.f. choke 18 to amplifier 19 and meter 20. Vibrations of the stator are additionally detected by an inductive transducer 8 comprising a coil 12 on the mass 2 and a magnet M on the housing 4 which vibrates with the stator.
