Abstract: 1,135,441. Fluid-pressure servomotor systems. IDEAL-STANDARD Ltd. April 5, 1966 April 5, 1965], No.14431/65. Heading G3P. A fluid control valve for controlling the flow of gas to a boiler comprises a main valve 28 carried by a diaphragm 9a and controlling the flow from an inlet 4a to an outlet 5a. The inlet is connected through passage 38, choke 11a and passage 41 to a first chamber 10a and the pressure in the chamber 10a is controlled by a valve 13acontrolling the flow to a weep passage 12a which is connected to the burners. A second choke 17a controls the flow of gas from chamber 10a to a second chamber 16a which has a weep passage outlet 45 connected to the burners through control valves responsive to flame failure, temperature and time. With the control valves open, the valve 13a opens to reduce the pressure in the chamber 10a which allows the inlet pressure to open the main valve. When one of the control valves closes, the valve 13a closes which causes closure of the main valve. The valve is of particular use in controlling large size gas flow pipes and provides a rapid closure response.

Title: Heating particulate thermoplastic materials
IPC: B01J8/18
Filed: 1964-04-09
Abstract: 1,059,091. Heating particulate thermoplastic material, Z. LORENIAN. April 9, 1964 [April 20, 1963], No. 14734/64. Heading F4U. In a method of heating particulate thermoplastic material, the material is conveyed along a tubular channel by a stream of hot air at a temperature higher than the softening temperature of the material. In an example, the material is contained in a hopper or container from which it is sucked and conveyed to a nozzle for feeding into a tubular channel in which a hot air stream flows. The material is carried along the tubular channel by the hot air stream and the length of the channel is such that the particles arrive at the end of the channel at a temperature at or above their softening temperature and in a free running condition. To prevent the material from sticking to the nozzle which becomes heated by the hot air stream the nozzle may be cooled. In a modified arrangement the material is fed into a cold air stream through a first nozzle and the particulate material and cold air is then fed into the tubular channel through a second nozzle. The material may be heated as required by varying the pressure and temperature of the air stream and/or the length of the tubular channel. The channel diameter may be reduced locally at the nozzle inlet to reduce pressure in the air stream.

Filed: 1962-04-17
Abstract: 1,033,141. Polyacrylonitrile filaments. COURTAULDS Ltd. April 16, 1963 [April 17, 1962], No. 14765/62. Heading B5B. Fibres formed by wet-spinning polymers containing acrylonitrile units are reacted with aldehydic cross-linking agents while the fibres are in a swollen condition and before they have been dried for the first time. The polymer may contain at least 10% of acrylonitrile units, suitably 10-20% acrylonitrile units and 90-80% butyl acrylate units, or approximately equal weights of acrylonitrile units and vinylidene chloride units, or at least 80%, especially 90-95%, acrylonitrile units, the balance being, e.g., vinyl acetate or methyl acrylate. A swelling agent may be applied to the neverdried fibre, and, simultaneously or subsequently, an aldehydic cross-linking agent may be applied. The aldehydic cross-linking agent, or a substance capable of giving rise to an aldehydic cross-linking agent, may be incorporated in the fibre during its production. Specified aldehydic cross-linking agents include formaldehyde, acetaldehyde and trichloracetaldehyde. Trioxane and paraformaldehyde may also be used in acid conditions causing conversion to formaldehyde. Specified swelling agents include water, dimethyl formamide, a mixture of dimethyl formamide with water, an aqueous solution of sulphuric acid, and trioxane as an aqueous solution or in the molten state. In Examples:-(1) An acrylonitrilemethyl acrylate polymer solution in aqueous sodium thiocyanate is wet-spun into aqueous sodium thiocyanate, and the never-dried fibres immersed in a bath containing sulphuric acid and paraformaldehyde. (2) An acrylonitrilemethyl acrylate polymer is dissolved in a mixture of dimethyl formamide and toluene and wet-spun into toluene and the never-dried fibres treated as in (1). (3) An acrylonitrile-butyl acrylate polymer solution in dimethyl formamide and containing 5% of trioxane is wetspun into water and the wet filaments treated with sulphuric acid. (7) An acrylonitrile-butyl acrylate polymer solution in acetone is spun into water and the never-dried filaments immersed in a bath containing sulphuric acid and paraformaldehyde. The treatment increases the wet modulus and tenacity of the fibres, especially at elevated temperatures, and enhances receptivity to disperse and acid dyes.

Filed: 1959-04-30
Abstract: 908,790. Pattern movement stopping-registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 30, 1959 [July 30, 1958], No. 14779/59. Class 106 (1). [Also in Group XL (c)] Fig. 4 shows a shift register in which each stage comprises bi-stable pairs of transistors T1 T4; T2, T3; T5, T6; T8, T9 and T11, T12. T1, T2, T3, T4, T5 and T6 are of PNP and T7, T8, T9, T10, T11 and T12 of NPN type in each stage. Information S is fed in at terminals 70 and is shifted by clock pulses applied to terminals 25 so as to successively appear at the outputs 63, 65 and its complement at outputs 64, 66. When a positive pulse indicative of binary 1 is present at input 70 and a positive clock pulse at input 25, transistors T4, T16, T8, T2 conduct and T7 remains non-conductive which gives positive output at 63. The next negative clock pulse makes T4, T16 cut off, T1, T13 conduct, T9 holds T2 conductive so that T11 conducts and T10 cuts off, a positive output being obtained at 64. It is shown that at the end of each clock period the input signal S has been transferred one stage further along the chain. The output 72 of the final stage may be connected back to the input 70 so that the device functions as a counter circuit.

Abstract: 1414139 Tipping containers TELEHOIST Ltd 22 March 1973 [30 March 1972] 15139/72 Heading B7B A vehicle has an open ended chassis 1, Fig. 1, and a parallelogram-type linkage on each side member 2 of the chassis, the linkages being connected to a frame 7 supporting a container with means to raise and to tip the frame. As shown in Fig. 1, the frame 7 is supported on links 8, 9 which are connected by longitudinal links 25, the frame being pivotally attached to the rear pair of links 8. Hydraulic rams 13 controlled by a tractor mounted control valve (not shown) are extended to raise frame 7 which engages beneath a top rim of the container Fig. 5 (not shown). On raising, the links 8 engage abutments 22 while latching struts 21 drop behind abutments 24 on the chassis after riding up ramp faces of the abutments. The rams are further extruded to lift the frame 7 off the front links 9 for rearward tipping about the pivotal connection to the rear links 8. As the frame is raised a latching member 16 moves automatically by means of a linkage 17, 18, 19, over a rearward projection of the container which is thus secured during subsequent tipping. For lowering the frame 7, ram pressure is temporarily applied to take the container load, and lever 26 is actuated to pivot, via linkage 28, bell crank lever 29 which engages a pin 30 of strut 21 to raise the strut above the abutment 24 for subsequent lowering of the frame under gravity. In another embodiment, Fig. 3, latch members 21a hook around abutments 24a on the chassis when the raised non-tapped position is reached. The latch member 21a may be released by a bell crank lever 29a actuated by release linkage 27, 28. Prior to tipping front frame pivot 12 is latched to front links 9a by a hook-link member 38 pivoted to frame 7 and engageable below upper link pivot 12. Movement of the rod 28 in the rearward direction swings member 38 clear of pivot 12 so that ram extension tips the frame 7 and container as before.

Abstract: 144,652. Pierrard, L. June 7, 1919, [Convention date]. Roller-slides. - In a roll-film magazine adapted to be attached to a camera in place of a darkslide, the winding handle is given a constant movement and the take-up spool given a decreasing rotation as the film is wound up so as to compensate for the increasing size of the take-up spool and draw the same length of the film into position for successive exposures. The winding handle 1 carries a pawl 3 which drives a ratchet wheel 4 in gear with the winding ratchet 8 of the take-up spool 22. The handle 1 moves between a shoulder stop 13 on a pivoted arm 14 and a fixed stop 12. On each return movement of the handle a connecting-rod 16 advances a counter wheel 17 which in turn advances a wheel 5 loosely mounted on the same shaft 2 as the handle 1. The wheel 5 has a cam 7 which is thus intermittingly advanced and retards the engagement of the pawl 3 with the ratchet 4 to a progressive extent for successive exposures. After the last exposure the pawl 3 engages a notch 24 in the cam 7 and on turning the handle J. the wheel 5 and counting disk 17 are advanced and in the return movement the pawl 3 engages behind the end 7<1> of the cam. On a further operation of the handle the pawl 3 both engages the ratchet 4 to wind up the last portion of film and advances the cam 7 back to its starting position and the counting wheel 17 to zero. The film spools 23, 22 and guide-rollers 30, 31 are mounted on an inner case 25 of the box 26. The film passes through, guides over a flat plate 27 and the outer case 25 has a sliding shutter 29.
