Abstract: 1,235,947. Spinning processes. MASCHINENFABRIK RIETER A.G. 26 March, 1969 [27 March, 1968], No. 15734/69. Heading D1F. In a mixing process, a pressurised air stream supplying entrained fibres of different origin is divided into secondary streams and flocks separated and deposited therefrom are compressed by air into individual flock columns each consisting of superimposed part flock columns of different flock origin. The uniformly descending columns are joined into superimposed fibre layers, forming an angle of not more than 90 with respect to the direction of column descent, which are continuously conveyed, laterally compressed, separated into flocks and reentrained in an air stream. In the apparatus shown, impact flocks, produced by a plucking roller successively engaging with circulating bales a - f of fibres and sucked away and blown by a fan 39 into a duct 8, are distributed by means of adjustably mounted deflecting heads 8' into chutes 1-6 of different heights from which air under pressure exhausts through perforated walls (29, 30) and side ducts (33, 34 and 35, 36). Thus, in each chute is assembled a compressed column formed by superposed part columns of fibres from different bales. On emerging from the chutes the columns form superposed layers which are removed and compressed by belts 18 and 20, seized and compressed by pairs of rollers 22, 23, opened by take-off rolls 24, 25, to form flocks of mixed fibres in a chamber 26 whence they are removed through duct 28 in an air stream supplied through intake 27. The chutes may be divided into groups separately fed from corresponding plucking machines through separate air ducts, Fig. 4 (not shown) and/or the chutes may be the same height with the conveyor belts (47, 46), corresponding to belts 18, 20, moving the layers in a direction at an angle of more than 90 e.g. 120, to the direction of fibre descent in the chutes, Fig. 3 (not shown).

Title: Safety controls for gaseous fuel burners
IPC: G05D23/02
Filed: 1944-08-17
Abstract: 590,606. Safety cut-off valves. MAY, P. (Grayson Heat Control, Ltd.). Aug. 17, 1944, No. 15756. [Class 135] A safety cut-off device for gas burners comprises a control valve for the main burner, manually re-set means which operate in response to a flame at the pilot burner to govern the operation of the control valve, a stop valve' which in one position establishes flow of gas to both the main and pilot burners and in a second position allows gas to flow to the pilot burner only, and stop means on the stop valve which prevent actuation of the manually operated resetting means except when the stop valve is in the second position. The manually re-set means comprises an armature 138 attracted by an electromagnet 144 energized by a thermocouple 166a exposed to the pilot flame. The control valve is also governedthermostatically in accordance with the temperature of water heated by the main burner. The construction described is similar to that described in Specification 590,605 but in this case the skirt of the stop cock 23 has a slot 180 which is only in alignment with the stem 174 of the re-setting button 170 when the cock is in the second or " pilot " position and thus it is only in this position that the control valve 190 can be re-set. The rigid arm carried by the stem 174 and the sleeve it operates are dispensed with since the main gas supply is cut off by the cock 23 during the re-setting operation.

Abstract: 770,098. Ammunition cartridges. RENVALL, H. G. June 1, 1955 [July 7, 1954], No. 15770/55. Class 9 (1). A cartridge adapted to be inserted in the tail of projectiles such as rockets and mortar bombs comprises a cardboard casing 1 closed at the base by apertured discs 2, which support one end of an axially disposed flash tube 5. A layer 3 of paper closes the outer end of the tube, which may be of celluloid. An annular air space 9 around the tube 5 is defined by cardboard sleeves 6, 8 disposed between rings 4, 7. The forward end of the tube 5 is supported in a plug 11 closing the cartridge and abutting a cardboard sleeve 16 which encloses the propellent charge 10. Within the tube 5, between a stopper 14 and a partition 12 of celluloid or other inflammable material, is a secondary ignition charge 13. A cardboard disc 15 covering the plug 11 has a central boss 15a to position the cartridge in the projectile. Cellulose acetate may be used to coat the outer surface of the cartridge. The cartridge may be fired by means of a percussion cap (not shown) adjacent the base, the flame from the cap being sufficient to perforate the layer 3 and pass through the tube 5 to ignite the charge 13 which in turn ignites the propellant. The propellent gases expand into the air space 9 before escaping from the cartridge. In a modification the flash tube extends through only part of the cartridge and is supported only at the base. The air space is then at the forward end of the cartridge and the secondary ignition charge is omitted. The air space in both forms of cartridge may contain a porous and/or easily compressible material such as cellulose plates formed by moulding celluloid or plastics powder or superposed corrugated plates which together form a cellular structure.

Filed: 1938-05-31
Abstract: 509,953. Rotary engines ; clutches. DEAN, E. May 31, 1938, No. 16214. [Class 110 (ii)] [Also in Group XXIX] In a rotary engine, pump, or the like, the vane tips follow a track a, shaped by measuring quantities radially from a base circle b, each quantity being of a value equal to half the difference between the maximum and minimum radii of the track and the sine of a multiple (according to the number of lobes of maximum radius desired upon the track) of the angle moved through. Thus, the quantity de in Fig. 1 is obtained by .3125 sin 45 degrees since there are two lobes to the track and the angle turned through from the datum point c is 22¢ degrees. Fig. 2 shows a pump with vanes h in a rotor i moving around a track g, and provided with inlets and outlets k, m. The shoes j may be spring-pressed outwards. The construction may be modified to act as a motor or compressor. Figs. 4, 5, 6 show the invention applied to a hydraulic clutch. A shaft t drives a casing u and a ring v attached.. Chambers w act as ports for fluid distribution to a rotor chamber x which has its track shaped in accordance with the invention. Abutments y, pivotally mounted in the chambers w, close automatically when the casing u rotates, and a pressure is built up between the abutments and the vanes z to cause rotation of the rotor 8. A plate 13 having teeth 14 meshing with teeth 15 on the abutment member, is loosely mounted on the shaft 9. To hold this plate in a central position, a sleeve 11, operated from a clutch pedal or the like, is moved to the left so that a projection 10 engages a hole 12 in the plate. The abutments y are then in the position shown dotted, Fig. 5, so that maximum slip may occur, and the clutch can free-wheel. To provide for one-way operation of the clutch, plungers 18 are moved laterally by the backward movement of the sleeve 11, to bring the plungers into alignment with the plate 13. A spring-pressed ball 20 holds each plunger in the desired position. Make-up liquid flows to chambers w from a space 22 via ports 21. The abutment y may be replaced by a rotary, sliding or other type 'of member. In a modification, rocking abutments are pivoted to a fixed casing, and have shoes j at their ends which bear continuously on the periphery of a rotor shaped according to the invention.
