Title: Improvements in mills for grinding paints and other materials
IPC: B02C4/34
Filed: 1926-03-19
Abstract: 274,162. Drysdale, H., and Smith & Blyth, Ltd., S. March 19, 1926. Roller - and - breast mills.-In a mill for grinding paint, inks, &c. and of the kind comprising an axiallyreciprocated roller and an adjustable grinding bar or block, the hopper, feedthroat, and grinding- block are hingedly mounted to enable the roller and housing surfaces to be cleaned. The surface of the grinding-block is made proportionate to the amount of wear occuring upon its contacting surface to obviate the need for endwise adjustment. As shown, the hopper 1 and throat 2 are carried in frame members 4 mounted at one side of the mill on a hinge spindle 5 having at one end a wheel 6 meshing with a worm 7 on a spindle 8 carrying a hand-wheel 9. The frame 4 is normally secured in the operative position by means of eye-bolts 10 pivoted to the framework 11. A weight 50 suspended from an arm 51 on the spindle 5 counterbalances the frame 4 when in its raised position. The hopper and throat are mounted in the frame 4 by means of lateral extensions 14 on the throat engaging over a pair of micrometer screws 15 engaging the frame and are held in position at the desired height by means of nuts 17, the throat taking its main bearing through a central pin 18. The grinding-block 20 is secured by screws 21 in a housing 19 integral with the throat 2 and hopper 1, and the pressure on the block is regulated by nuts 26 bearing upon springs 27 on bolts 24 which pass through a crossbar 22 secured to the members 4 bv nuts 23. Bolts 25 for adjusting the block pass through the cross-bar 22 and are formed with milled heads 28. The roller 3 is reciprocated on its shaft 30 by means of a cam-grooved pulley 33 engaging a coned roller 34, the spindle of which is carried in a bracket 35 secured to the framework. Setscrews 36, 37 are provided for adjusting the position of the roller 34. The bearings 38 of the shaft 30 may be adjustable by means of micrometer screws at each end mounted in the framework 11. A collecting-box 40 at the front of the mill has its base constituted by a scraper blade 41 pressed by springs 42 against the roller. The box 40 is supported on a rod 44 carried by brackets 45, one or more slotted lugs 46 on the under side of the blade 41 engaging over the rod 44. The roller and the walls of the hopper and throat may be hollow to contain a heating or cooling medium.

Title: Improvements in fuzes for ammunition projectiles
IPC: F42C9/18
Filed: 1941-06-17
Abstract: 551,654. Projectile fuzes. MEFINA SOC. ANON. June 17, 1941, No. 7651. Convention date, July 9, 1940. [Class 9 (i)] A projectile fuze of the type in which a striker is operable by impact or by a spring in the event of the target being missed so that the projectile is destroyed before reaching the ground, has a tubular pellet surrounding the striker and coacting with centrifugal members to lock the striker and pellet against firing movements. The striker 10 is surrounded by a tubular pellet 13 adapted to be thrust against centrifugally released stop members 11 by a spring 14. The pellet is provided with radial apertures in which are disposed round-ended loose members 15 coacting with an inclined surface 16 on the projectile body so that during initial rotation of the projectile as it leaves the gun, the pellet is raised against the action of its spring and the stop members 11 are released and fly outwardly by centrifugal force, so that the projectile is armed. If the target is struck the impact thrusts the striker forward to strike the detonator 18 but in the event of a miss, the rotation of the projectile falls and eventually the thrust of the spring 14 overcomes the centrifugal raising effect between the members 15 and the inclined surface, and the striker and pellet are actuated by the spring to fire the detonator. Specification 516,564. is referred to.

Abstract: Red leaf and other impurities are extracted from wholly or partly manufactured tea by suction nozzles connected by pipes to a suction duct forming a bench of seats for operatives holding the nozzles, one in each hand.  Stationary, revolving or vibrated tables or a travelling belt support the tea in front of the operatives and slope downwardly from hoppers supplying tea at the upper end towards the conduit so that the tea, after picking, is discharged at the lower end into a container.  The suction duct has one or more doors for removing the impurities and baffles near the doors preventing the impurities reaching the suction fan.
Patent GB-1375392-A (GB)
IPC: H04J3/12
Filed: 1972-02-23
Abstract: 1375392 Automatic exchange systems; tone generators MARCONI CO Ltd 23 Feb 1972 [26 March 1971] 8035/71 Heading H4K A tone generator, e.g. for producing dialling, engaged or out-of-order tones in a T.D.M. exchange system comprises a digital code store having a plurality of individual code store positions and means for storing in such positions a digital code representative of an instantaneous amplitude value of a tone to be generated and further comprising means for sequentially  sampling each of the stored codes in a predetermined order whereby a sequence of digital codes is obtained which, when decoded, provides the required tone. A generator for supplying, to a P.C.M. highway via a multiplexer 11 the codes representing either a 400 Hz or an 800 Hz tone includes two diode matrix stores 5, 6 one for each tone. The 400 Hz tone store comprises 5 storage locations which each store a 7 bit binary code and the store is read by sequentially pulsing lines 1-8 of 1 out of 8 decoder 4 with a binary one. The five codes represent five instantaneous amplitude values of one quarter cycle of the frequency tone to be produced, and the five codes are simultaneously applied to AND gates G8-G12 via inverting gates G20-G24 respectively. These AND gates are opened by applying pulses to them via OR gates G1-G5. The operation is as follows:-a fixed high frequency generator is used to pulse wires 1-8 of 1 out of 8 decoder 4 sequentially, each wire being pulsed once every eight cycles. This frequency divided by 8 is further divided by 32 by divider 3 to produce an 8 KHz signal which sequentially pulses lines 0-9 of 1 out of 10 decoder 8. By this arrangement gates G8-G12 and then gates G12-G8 are sequentially opened, each gate being open for a time corresponding to the corresponding data store position being read 32 times to enable the code to be fed to all 32 time slots of the P.C.M. highway if necessary. Ten successive codes are hence fed via the gates G8-G12 to the same time slot in 10 successive frames, the codes representing 10 successive amplitude values of one half cycle of a 400 Hz tone. In order that negative codes need not be generated for the negative half cycles of the tone a polarity bit is introduced using divide-by-two circuit 10 which causes gate G7 to produce a binary 1 before each code of one half cycle of the tone and a binary 0 before each code of the following half cycle. The 800 Hz tone codes are similarly produced but only two amplitude values are used for each quarter cycle. The tone generator of Fig. 2 may be triplicated to enable majority voting techniques to be used for the tones produced.
