Title: Improvements in and relating to automatic electric control systems
Inventor: WARREN RICHARD FREEMAN
IPC: B21B37/16
Filed: 1961-06-07
Abstract: 916,404. Automatic thickness control. INDUSTRIAL NUCLEONICS CORPORATION. June 7, 1961, No. 20619/61. Class 38 (4). The thickness of a strip 10 issuing from the stands 12, 14 of a rolling mill is measured by a radiation detector 62 coupled to a recording device 64. The measured thickness is compared with a desired thickness set by a target indicator 96, and an error signal representative of any difference is applied to the input of an amplifier 162 the output from which controls a servomotor 186 which repositions a vernier rheostat 32 in the control circuit of a motor 16 driving the stand 14 whereby the speed of the motor is varied and the strip tension thereby regulated to maintain the thickness constant. The servomotor 186 also drives a tachogenerator 204 which produces a second signal proportional to the speed of readjustment of the rheostat 32, and this second signal is applied to the input of the amplifier 162 in opposition to the error signal, so that the adjustments are performed in accordance with the time integral of the error signal. Transportation lag, inertia &c. are compensated for by a phase lead circuit, comprising resistors 154, 156 and capacitor 158, for the error signal.

Title: Clothes washer machine
IPC: D06F37/36
Filed: 1960-06-13
Abstract: 895,827. Washing-machines. GENERAL MOTORS CORPORATION. June 13, 1960 [June 25, 1959], No. 20643/60. Class 138 (2). [Also in Groups XIII and XXIV] To obtain controlled slipping of a low-speed belt 94 in a two-speed drive used during both the spin drying and agitating operations performed by a washing machine, a drive unit comprising a two-speed reversible electric motor 44 having a drive shaft 62 carrying low and high-speed pulleys 78, 76 is pivoted about its centre of gravity at 152 and is biased to turn by springs 104 to tension both a belt 92 connecting the high-speed pulley to a driven pulley 48 and the low-speed belt 94 connecting the low-speed pulley to a driven pulley 50, the tension of the springs being adjustable. The driven pulleys 48, 50 rotate a casing 46 containing the mechanism (not further described) producing both the spin drying and the agitating motions. The high-speed belt 92 is a conventional V-belt and the low-speed belt 94 is neoprene coated. Change of ratio is effected by a solenoid 84 acting through a lever 82 pivoting at 83 to slide a clutch disc 80 rotating with the motor drive shaft 62 either upwards of Fig. 4 to engage a friction disc 86 thereon with the high-speed pulley 76 or downwards to engage dogs with corresponding dogs upon the low-speed pulley 78. Adjustment of the position of the ratio shift lever 82 is obtained by thumb-screws 168, 178 threaded upon the shaft 166 of the solenoid 84, and coacting with a surrounding spring 174 to connect the ratio shift lever resiliently to the actuating armature. The pivot bolts 152 mounting the motor are carried in arms 98, 100 of a support secured by bolts 120 to a resiliently mounted snubber frame 52 within the washing machine, slots 102 through which the bolts are passed to enter tapped holes in the mounting bracket 114 permitting lateral adjustment of the two arms for variable tensioning of the drive belts 92, 94. The springs 104, 106 are each secured at one end 108 to brackets on the electric motor 44, and at the other end are attached to one or other of a number of holes 130, 136 according to the tension required. The lateral position of the motor 44 is adjusted by means of the bolts 120 and the tension of the springs 104 is also adjusted, to obtain a tension of 30-35 pounds in the top belt 92, which is then found to give sufficient slipping in the lower belt 94 to prevent " hunting " of the starting device controlling the motor. The motor shaft 62 also drives a pump used to empty the washing- machine receptacle. In a modification, the springs 104 are replaced by a single strip spring engaging the motor casing, Fig. 7 (not shown). The cycle of washing operations is controlled automatically by means not further described.

Title: Improvements in carboxylation of alkali metal salts of phenols
IPC: C07C51/15
Filed: 1938-07-12
Abstract: 511,393. Hydroxy carboxylic acids. CALCO CHEMICAL CO., Inc. July 12, 1938, No. 20654. Convention date, July 31, 1937. [Class 2 (iii)] Alkali metal salts of phenols or naphthols, particularly #-naphthol, are carboxylated by the action of carbon dioxide on a substantially - anhydrous solution ; thereof in a solvent having as the major component pyridine, compounds containing condensed pyridine rings or their homologues. Examples of suitable solvents are pyridine, the picolines, lutidines, and collidines, quinoline, quinaldine, lepidine, isoquinoline or mixtures of such compounds obtained from the acid soluble coal tar fraction. Phenols mentioned are phenol, cresols, chlorphenols, naphthols, hydroxyanthracenes, '5, 6, 7, 8-tetrahydro-2-naphthol, p-benzylphenol, hydroxycarbazoles and hydroxybenzocarcazoles. The prepared alkali metal salt may be directly dissolved in the solvent, or the phenol may be dissolved in the solvent and'alkali added, water formed being removed with excess alkali as a layer which separates on warming below the alkali phenolate solution, or by the use of lime or calcium carbide as dehydrating agents, or by distillation with or without a portion of the solvent. Wet 'solvent may be re-dried by refluxing over quick lime. In the case of phenols prepared by alkali fusion of sulphonic acids, the ground salt may be extracted with the solvent, alkali phenolate being dissolved and inorganic salts left. The dry phenolate solutions are reacted with carbon dioxide at ordinary or slightly elated temperatures, and the sodium' salts of the hydroxycarboxylic acids precipitate. When the reaction is effected at raised temperature, the pressure must be increased to increase the solubility of the carbon dioxide in the solvent. In the case of sodium betanaphthalate, two isomeric acids are formed, the salt of the 2-1 isomer being formed at lower temperatures and the more valuable 2-3 isomer at higher temperatures, e.g. 230-270‹C. Preferably in this case carbon dioxide is introduced at 230- 270‹C, the pressure being raised slowly and not too high to avoid formation of the 2-1 acid which tends to form a naphthoxanthene and tarry by products. Some pure betanaphthol is preferably present in the starting solution. Iron apparatus is not suitable. Nickel and its alloys are suitable materials. Examples describe the preparation of (1) sodium 1-hydroxy-2- naphthoate from sodium alpha-naphtholate in pyridine ; (2) the sodium salt of 5, 6, 7, 8 tetrahydro-2-hydroxy-3 naphthoic acid from the corresponding phenolate in pyridine ; (3) the sodium salt of 2-hydroxy-3 naphthoic acid from sodium #-naphtholate in pyridine or quinoline or an acid soluble coal tar oil of boiling point 250-260‹C ; (4) the potassium salt of 2-hydroxy- 1 naphthoic acid from potassium #-naphtholate in pyridine. Specifications 384,619 and 483,795 are referred to.

Abstract: 1,099,508. Centrifugal governors. F. HEINZMANN. May 17, 1965 [May 22, 1964; July 25, 1964], No. 20665/65. Heading G3B. A centrifugal governor comprises a rotatable body, a pair of flyweights 3 pivoted at 4 to the body, a control member 9 carried by the governor body and operatively connected to the flyweights for movement thereby, and at least one spring means 6 carried by the governor body and of U or channel shape with the ends 6a of the U directly engaging the outer peripheral surfaces of the flyweights. The spring means is secured by screws 7 to a flyweight carrier 2 and engages balls 8 set in the outer surfaces of the flyweights which are of arcuate shape and connected by pins 10 to the control member or sleeve 9 for operating the fuel metering or distributing device of an I. C. engine against a weak spring-bias. In a modification Figs. 5 and 6 (not shown) the spring is secured to a groove in the control sleeve by a snap ring 11 which may be replaced by another of different thickness to vary the governor characteristic. Alternatively, the characteristic may be varied by providing a series of holes in the flyweights to enable the position of the balls 8 to be varied. In further modifications, the balls are replaced by knife edge contacts with the spring, rollers are used in place of balls and the spring is provided with apertures or with cylindrical or spherical sockets to receive them. An adjustable connection between the spring and the carrier may also be provided in the form of a slot or a plurality of holes to receive the fixing screws and a multi-element spring may be used. In Fig. 33 (not shown) the governor spring may be pre-stressed by screws 29 which in Fig. 36 (not shown) the spring stress is varied by shifting a sleeve 32 riveted to the spring loops 31a or provided with a flange which adjustably and partially embraces the spring. A number of springs brought into operation in succession may be used to provide the governor with a discontinuous characteristic and one of the springs may be provided with separate adjustment means and co-operate with either a spring or fixed support.

Abstract: 947,636. Synthetic polymer wrinkle-finish films. SWIFT & CO. Feb. 24, 1960 [July 16, 1959], No. 20700/63. Divided out of 947,635. Heading B5B. [Also in Divisions B2 and C3] The invention comprises wrinkle-finish films based on a resin mixture comprising a vinyl halide polymer having at least 50% by weight vinyl halide units, and a polyepoxide. The preferred process is to apply such a mixture as a continuous film on the surface of a supporting object, to apply an epoxy curing agent to the surface of the film, and to subject the film to curing conditions to cause the surface to shrink and pucker. The supporting object and film may be heated in order to fuse the film, before the fibre is subjected to curing conditions. And the curing conditions are normally the application of heat. Long lists of suitable compounds are given (see Division C3), the preferred ma terials being P.V.C., epoxidized linseed oil, and a variety of polycarboxylic acids and anhydrides and boric acid. The vinyl halide polymer and the polyepoxide are preferably intimately mixed and applied as a plastisol, organosol, latex, solution or dry mix, by casting, milling, dipping, brushing, knife coating, roller coating or spraying. The curing agent may be applied as a spray from solution in a conventional solvent (e.g. lower alkyl alcohols and ketones, lower boiling chlorinated hydroacrbons and aromatic hydrocarbons), as a dispersion in a liquid carrier, in dry particulate form or as a gas. The only substrate mentioned is steel. One or both sides of the fibre may be wrinkled while the film is supported or unsupported.

Abstract: 652,126. Phase displacing. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd., and BEAUFOY, R. Aug. 5, 1948, No. 20738. [Class 38 (ii)] [Also in Groups XXXVI and XL (c)] A phase-splitting circuit for providing from a single input voltage of frequency F two voltages of the same frequency but differing in phase by 90,degrees, for use in an oscillator circuit (see Group XL (c)), for producing a circular time base for a cathode-ray tube, comprises two series circuits connected in parallel between the input terminals, the two circuits comprising in the order named a resistor and a capacitor, and a capacitor and a resistor, the product RC of the resistance R and the capacitance C in the two circuits being equal. One pair of output terminals is coupled to the resistor in one circuit and one pair to the capacitance in the other and the values of R and C are such that F=1/2 #RC. In Fig. 2 the phase splitter which is constituted by elements 20, 21 and 23, and produces the quadrature outputs across resistor 20 and capacitor 22, is used as one arm of a bridge 14, 15, 16, 17 which constitutes the feed-back network of a resistance-capacitance oscillator. The capacitors 19, 20 and 23 are equal and are ganged so that when they are varied to change the frequency, the two output voltages remain substantially constant in amplitude and in phase quadrature. The frequency may be varied by altering the values of resistors 14 and 15. Constant amplitude may be ensured by making resistors 14 and 15 temperature sensitive or by inserting a resistor in series with arm 16 of the bridge. Specification 653,815, [Group XL (c)], is referred to.
Patent GB-464755-A (GB)
Title: Fermentation of beet molasses
IPC: C12P7/28
Filed: 1935-07-23
Abstract: An essentially soluble carbohydrate mash containing beet molasses as a major component is fermented by means of bacteria of the group clostridium saccharo - acetobutylicum, in the presence of proteinaceous material from grain alcohol distillery slop.  The presence of ammonia nitrogen in other than relatively low concentration is usually detrimental.  Mineral nutrients such as phosphates are added as required.  The mash should be maintained more alkaline than is usual for other carbohydrate mashes and should fall within the final range pH 5,5 to 7,0, preferably 5,7 to 6,5.  The alkalinity of the beet molasses is usually sufficient to ensure this but, if necessary, the correct pH may be ensured by continuous or semi-continuous neutralization with soluble alkalines, or by an insoluble neutralizing agent.  The slop may be that from the malt, the amylo or the acid hydrolysis process, and is used in proportions of 5 to 50 per cent by volume, preferably 10 to 20 per cent.  In examples: (1) a mash containing a beet molasses and grain alcohol distillery slop was fermented with clostridium saccharo-acetobutylicum a ; (2) as in (1); (3) as in (1) and containing (NH4)2 HPO4; (4) as in (1) and containing CaCO3; (5) as in (1) and containing K2HPO4; (6) a mash of 50 per cent beet molasses and 50 per cent hydrol, grain alcohol slop and (NH4)2HPO4 fermented by the same bacterium. With a mixed mash as in (6) the fermentation may be started in the molasses and the hydrol-slop mixture (2) added. Specifications 437,121, 450,530, and 464,127 are referred to.
