Title: Improvements in or relating to finishing textile fabrics
IPC: D06M15/09
Filed: 1940-12-05
Abstract: 545,702. Treating textiles with liquids ; cellulosic compositions. HERCULES POWDER CO. Dec. 5, 1940, No. 17334. Convention date, Aug. 2. [Classes 2 (ii) and 15 (ii)] Textile fabric is impregnated with an aqueous emulsion of a water-immiscible solution in a volatile organic solvent of a solid film-forming composition comprising ethyl cellulose and a plasticizer therefor in the proportion of 30- 100 per cent. by weight of the ethyl cellulose. The treatment is such that there is deposited in the fabric an amount of dry plasticized ethyl cellulose composition insufficient to fully impregnate the individual threads of the fabric and insufficient to fill the interstices between the threads. The amount of emulsion remaining in the fabric is such as to leave, on drying, an amount of plasticized ethyl cellulose composition not in excess of about 5 per cent. by weight of the untreated fabric. The water and volatile solvent are evaporated from the emulsion contained in the fabric and then the fabric is pressed at a temperature at which at least incipient fusion of the ethyl cellulose composition occurs, e.g. 180‹-320‹ F. The treatment imparts a permanent finish or size without giving a stiff or starched appearance. The treated fabrics have a soft handle and are pervious to moisture and air. The ethyl cellulose used may have an ethoxyl content of 41-51 per cent. The plasticizer may be dibutyl phthalate, triphenyl or tricresyl phosphate, methyl or ethyl phthalyl methyl or ethyl glycollate, di-(p-tert. butyl phenyl) mono- (5-tert. butyl-2-xenyl) phosphate, or white mineral oil. The emulsifying agent for preparing the aqueous emulsion may be an alkali metal salt, sodium lauryl sulphate, sodium stearyl sulphate, sulphonated castor or olive oil, sodium stearate, potassium oleate, sodium oleate, sodium butyl or isopropyl naphthalene sulphonate. The organic solvent for the ethyl cellulose composition may be toluene, xylene, petroleum hydrocarbons, naphtha, butanol, or pine oil. The textile fabric may be of cotton, wool or rayon. In an example, a solution of ethyl cellulose, triphenyl phosphate, xylol, Hi-flash naphtha and butanol is mixed with water containing potassium oleate and the emulsion completed by passing the mixture through a homogenizer. Cotton fabric is passed through the diluted emulsion. The excess liquid is squeezed out and the impregnated fabric is ironed dry at 240‹ F. The finish is permanent to repeated launderings.

Title: A motor for the conversion of heat to power
IPC: F01K11/04
Filed: 1938-06-13
Abstract: 511,639. Vapour engines. NOBLE, P. W., and NOBLE, H. June 13, 1938, No. 17463. [Classes 110 (iii) and 122 (iii)] [Also in Group XXVIII] Comprises a motor for the conversion of heat into power wherein an air-free rotor comprising a vapour generator and a condenser either of which surrounds a rotary or reciprocating engine coaxial therewith operated by steam or other vapour.. The torque distributed is balanced by a pendulum. ' A vapour generator 2 rotates in a refractory enclosure 3 supported by a sheetmetal structure 4 on a stationary frame 5.

Title: Telegraph signal bias and distortion meter
IPC: H03M1/00
Filed: 1963-05-03
Abstract: 1,036,475. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. May 3, 1963 [May 8, 1962], No. 17537/63. Heading H4P. In a distortion indicator in which received bits gate high-speed clock pulses to a counter, the output of the counter is converted to a magnitude, related to the count, which is displayed on a meter. The embodiment described employs 64 clock pulses per bit, and the counter has a capacity of 96. The counter operates during space bits and, to cope with two or more adjacent space bits, it is arranged that the first five stages are reset to zero after every 32 pulses and the sixth stage is set only during counts corresponding to 1-1¢, 2-2¢ &c. bit lengths. In this way, when the received space bits terminate, the count transferred to the following circuitry will be 64 minus the marking bias or 64 plus the spacing bias. The analogue value of the count is obtained and backed off by an amount equivalent to a count of 64, the resultant signal feeding a centre zero meter to indicate the distortion. The analogue is also fed to a circuit comprising a peak detector and an integrator feeding a meter which shows the shortest average plus length ratio.

Title: Machine and method for processing photographic film
Inventor: MATHESON RALPH GLENDON
IPC: G03D13/00
Filed: 1968-04-11
Abstract: 1,224,187. Reversing gearing. R.G.MATHESON. 11 April, 1968, No. 17599/68. Heading F2D. [Also in Divisions G2-G3] A gear-box can be set so that the Output shaft periodically and automatically reverses its direction of rotation. As shown, the drive from an electric motor 100 is transmitted via a chain 102 to the input shaft 131, which passes into the gear-box 101 and drives a shaft 120. A worm 121 on shaft 120 transmits the drive, via a worm-wheel 129, to a shaft 122 mounted at right angles to shaft 120. Shaft 122 is spring- loaded, and by turning a handle 128 worm-wheel 129 can be brought into or out of engagement with worm 121. An eccentric cam 130 is mounted on shaft 122, and revolves whenever wheel 129 is rotating. The input shaft 131 has an axial recess 132 in which slides a cam follower 133, spring-urged into engagement with cam 130. A collar 138 is slidably mounted on a sleeve 137 which surrounds shaft 131. A crossbar 141 extends through collar and follower to tie them together, and passes through axial slots 142 in sleeve 137 and shaft 131. Thus, collar 138 and follower 133 slide together along shaft 131. A spring-loaded pin 143 on collar 138 can engage, when the collar moves to the right (Fig. 7), in a hole in a gear 136 freely mounted on shaft 131, and another spring-loaded pin 144 can engage, when the collar moves to the left, in a hole in a similarly mounted gear 135. Thus, when worm 121 is engaging with wheel 129, the rotating eccentric cam 130 drives the follower shaft 133 first in one direction and then the other, so that shaft 131 is engaged with gears 135 and 136 alternately. The output shaft 119 carries a pair of gears 147 and 148. Gear 147 meshes directly with gear 136, but gear 148 meshes with gear 135 via an idler gear 149. Thus, gears 135 and 136 drive shaft 119 in opposite directions. By adjusting the length of travel between collar 138 and one or other of gears 135, 136, the rotation of output shaft 119 can be made longer in one direction than the other, and by disengaging wheel 119 from worm 121 the reciprocating mechanism can be disabled so that output shaft 119 can rotate continuously in one direction or the other. The gear-box is described in connection with a film processing apparatus (see Divisions G2-G3), in which it is used to control the movement of a film strip through a tank of processing liquid.

Title: Spectrometric cell structure
IPC: G01N21/03
Filed: 1959-05-25
Abstract: 856,087. Spectrometer cells. NATIONAL RESEARCH COUNCIL. May 25, 1959 [June 3, 1958], No. 17765/59. Class 97(1) A cell for containing samples of liquid for infra-red spectroscopic analysis is made as a unitary body from a single piece of material. For preference, rock salt is used, but other materials which are transparent to infra-red radiation may also be used; for example, the halides of the alkali-metals, silver, barium calcium and lead, and also arsenic-trisulphide. If the cell is made from rock salt, a single crystal must be used of sufficient size to allow the cell to have dimensions of the order of 2cm x lcm x 0.5cm. The cell cavity is formed by ultrasonic impact drilling and is normally rectangular in shape with planar parallel faces as shown in Fig. 1. The uppermost portion of the cavity is first drilled by conventional means to form a circular aperture for a stopper. If it is desirable to have a small opening in order to minimize evaporation, this is drilled in a separate piece of rock salt which is then bonded to the top of the cell by moistening with aqueous sodium chloride and clamping under pressure at a temperature of 110‹C for 12 hours. To obtain a very thin cavity without deformation of the grinding tool, the tool is reinforced with cylindrical bars on both sideedges. The resulting cavity will then have a dumb-bell shaped cross-section as in Fig. 8 in the central parallel-sided portion of which the test liquid is held by capillary action without the cylindrical portions having to be filled.

Abstract: 549,957. Specific-gravity estimating apparatus. UNITED AIRCRAFT CORPORATION. Dec. 17, 1940, No. 17779. Convention date, Dec. 27, 1939. [Class 97 (iii)] For estimating continuously the density of a fluid such as a gas or air a casing 10 is divided into three intercommunicating chambers 12, 14, 16 together with a flow channel 18. The chamber 12 is provided with a pump 66 which passes into chamber 14 a definite volume of gas for a particular constant speed of the pump. A valved orifice 34 provides communication between the chambers 14, 16 and the chamber 16 communicates with the flow channel 18 by duct 22 adjacent a constriction 70 in the flow channel 18. The valve 36 is provided with a stem 38 under the control of a spring 56. The pressure difference at opposite sides of the orifice 34 is a function of the density of the gas and is measured by means of a manometer 65 or operates a servomotor connected to the chambers at 62, 64. The orifice 34 is conditioned to the volume of gas passing and therefore to the particular constant speed of the pump by means of a speedresponsive device or governor 40 driven from the pump 66 by gears 72, 74, 76 and acting on the stem 38 of the valve 36. The pump 66 may be driven by a flexible shaft or by means of the gas flow.
