Title: Improvements relating to the treatment of textiles to render the same highly resistant to shrinkage and felting
Filed: 1955-04-25
Abstract: Goods composed wholly or partly of wool are treated with dry chlorine until the amount of chlorine combined with the wool amounts to 0.2-1.5 per cent by weight of the wool, and are then impregnated with 1.0-3.5 per cent (by weight of the goods) of a melamine-formaldehyde condensation product and subjected to a drying or finishing treatment to cure the resin.  Goods composed wholly of wool are dried to a moisture regain less than 9 per cent by weight and cooled to 60-90 DEG  F., prior to the treatment with dry chlorine and, after chlorination, are washed in an aqueous bath, dried to a moisture regain less than 12 per cent by weight and impregnated with the melamine-formaldehyde condensation product.  Goods composed of wool blended with other fibres are subjected to the same sequence of operations but, prior to chlorination, the drying is taken to a moisture regain less than 4 per cent and the cooling to 32-55 DEG  F. Before or after chlorination the goods may be subjected to an aqueous alkaline scour containing soap or a synthetic detergent.  The goods to be treated may be already dyed or may be dyed after the chlorination and before or after the resin treatment.  The impregnating composition may be an acid colloidal solution of an alkylated melamine-formaldehyde and may contain a non-ionic detergent.  The resin may be cured at atmospheric or elevated temperature in a drying chamber, brattice dryer or tumbler dryer. The chlorination may be effected under vacuum in an autoclave.  The resin bath may be re-used with replenishments of resin and periodic additions of acid.  In the wool blends the other fibres may be of polyamides, polyesters or cellulose.

Abstract: 1,042,740. Compressors. INGERSOLLRAND CO. March 22, 1965 [March 27, 1964], No. 12031/65. Heading F1N. In a compressor, Figs. 1 and la (not shown), wherein a plunger 21 reciprocates in a packing assembly 19 to compress gas supplied to a compression chamber 18, the heat generated by the friction between the plunger and the packing assembly is absorbed by conducting the compressed gas or the gas to be compressed through passages 39 disposed adjacent the packing assembly 19. The compression chamber 18 is closed by a three part valve body 23, 24, 25 having an inlet valve 28 and a concentric annular outlet valve 32. Gas such as ethylene compressed in the chamber 18 passes through passages 29, 30 in the valve body sections 23, 24 and past the outlet valve 32 into an annular outlet chamber 33 formed in the periphery of the body section 25. The compressed gas passes from the chamber 33 to passageways 38, formed between a valve sleeve 26 and a housing 11, and communicating with the passages 39. The passages 39 are defined in part by the outer surface of the packing assembly 19 and hence the compressed gas flowing therethrough to an outlet 35 cools the packing assembly. In a second construction, Figs. 4 and 4A (not shown) gas is admitted to the compression chamber after first cooling the packing assembly.

Title: Improvements in or relating to prepayment meters
IPC: G07F15/02
Filed: 1935-04-23
Abstract: 455,620. Prepayment mechanism for meters. GRASEBY, R. C., Venner Works, Kingston By-pass Road, New Malden, Surrey. April 23, 1935, No. 12171. [Class 27] In prepayment meter mechanism in which coins of different diameters are inserted through a single slot into a turntable receiver and the diameters gauged to determine the extent the mechanism is set forward, the coin gauging means comprises two elements which are each movable in the direction of the width of the coin so that they can be opened to receive the coin between them and closed on the coin to gauge it and which are turnable with the receiver. The coins are inserted through a slot 2 at the top of a casing 1, Figs. 1 and 2, into a receiver formed by a drum 4 provided with a coin-pocket 5, switch closing means 6 and actuating means 7 operable by a handle. Most of one-half of the drum is cut away but enough is left to form one wall 4a, of the pocket 5. To the external face of the wall 4a rockers 8, 9 extending downwardly are pivoted and each has a spring 11 which tends to move it towards the other, the spring of the rocker 9 being stronger than that of rocker 8. The rockers are guided in their movement by rods 10 and each has a lug 8a, 9a respectively, extending through the wall 4a, the two lugs acting conjointly to gauge the coin. The free ends of the rockers co-operate with fixed cams 12a, so that when the drum is in the position shown in Fig. 1, to receive a coin or turned halfa revolution therefrom, the rockers are moved apart. When the drum is turned through 90‹ the cams allow the springs 11 to move the rockers towards each other. If a penny 17 is inserted, Fig. 3, the rocker 9 acts through the penny and, since its spring 11 is the stronger, moves the rocker 8 until this is stopped by the end of the drum. The diameter of a penny is such that the end of rocker 9 then engages a star-wheel 15 and during the remaining rotation of the drum rotates this wheel 15. When a shilling is inserted, the rocker 9 pushes the rocker 8 as before until rocker 9 meets an inner stop formed by a bridge piece 4c. The end of the rocker 8 is then in position to engage and rotate a star-wheel 14. The star-wheels 14, 15 rotate a shaft 13, one twelve times as much as the other, through an epicyclic gear comprising a compound planet wheel constituted by a pinion 20 and a crown-wheel 21 meshing respectively with a crown-wheel 22 and pinion 23 secured to the star-wheels 14, 15. The planet-wheel is on a stub-shaft fixed to the shaft 13. To prevent backward rotation of the drum with a coin therein after a star-wheel has been actuated, a spring- pressed detent 25 is pivoted to the casing 1 at 24, Fig. 2, the free end of the detent being provided with teeth 27 which engage the edge of the coin. The drum has a transverse slot 26 which allows the requisite movement of the detent.

Title: Improvements in flying machines
IPC: B64C3/38
Filed: 1920-05-03
Abstract: 157,053. Tekniske Forsogsaktieselskab. Jan. 15, 1920, [Convention date]. Machinery, utilizing inertia to obtain movements in.-In flying-machines having supporting planes which are reciprocated in a horizontal or slightly curved path and have their angle of incidence automatically reversed at the end of each stroke, the planes are reciprocated by centrifugal mechanism such as that described in Specification 157,870. In one form, Fig. 5, the plane T is supported by a pair of reciprocating carriages g sliding on fixed rods a<1> between adjustable buffers h<1>, h<2>. The reciprocation is brought about by the variation in the resultant of the centrifugal forces due to the rotation of weights o', o<2>, o<3> about the shaft 1, the weights o<1>, o' being connected together and rotated in the opposite sense to the weight o<2>. The weight o<2> is carried by an arm s<2> from a sleeve n<2>, and the weight 0<3> by an arms s' from a sleeve n<3>, and the sleeves n<2>, n' are driven in opposite senses by the gears r<4>, r <3> and r<2>, r<1> respectively which slide along the driving-shaft w as the plane is reciprocated. More than three weights may be used. In a modification, in which the plane moves in a slightly curved path, the plane is carried by an arm which is oscillated in a vertical plane about a pivot at its lower end; the weights rotate around the arm in the same way as the weights in Fig. 5 rotate around the shaft 1; and the gears are driven by a flexible shaft.

Title: Thermal controller
IPC: G05D23/24
Filed: 1958-04-17
Abstract: 827,701. Automatic thermal control systems. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. April 17, 1958 [May 22, 1957; Jan. 29, 1958], No. 12213/58. Class 38 (4). In a thermal controller for an image transfer printing machine, a Wheatstone bridge 47 supplied at a low voltage from the secondary of a mains frequency transformer 42 has shunted across one arm a thermistor 54 kept at platen temperature. The out-of-balance signal from the bridge is amplified by a triode 63 and applied to the grid of a thyratron 71. When the out-of-balance signal exceeds a predetermined value and is in phase with the anode voltage of the thyratron derived from the primary of the transformer 42, a relay coil 98 is energized and a pair of contacts 98A, 98B, in parallel, close the supply to a platen heater, not shown. The amplified out-of-balance signal is also rectified by a diode 143 and the resultant negative-going pulses are applied to the grid of a triode 70 which is cathode biased from the primary of the transformer 42 through a resistor 155. At a predetermined amplitude, the negative going pulses on the grid reduce the anode current of the valve 70 so that a relay 91 is de-energized, cutting off the supply to the machine drive control circuit, not shown. The platen temperature is adjusted by a variable resistance 57, and a variable resistance 148 adjusts the platen temperature limits at which the machine drive control circuit is energized. In another embodiment, Fig. 2, not shown, the triode 70 is self-biased and the rectifier diode is so arranged that an increase in the rectified out-of-balance signal applied to the control grid energizes the relay coil 91 and break the supply to the machine drive control circuit. Specifications 703,336 and 782,633, [both in Group XVI], are referred to.
