Filed: 1951-05-28
Abstract: 703,094. Sifting and separating apparatus. NEUHAUS, R. May 28, 1951, No. 12521/51. Class 117 In an apparatus for cleaning and sorting seeds the seeds are fed from a funnel 1 through an opening 4 controlled by an adjustable member 5 to a dust sieve 6 fixed in the reciprocating sieve box 7, the dust passing into a box 8. A fan 11 blows air through a further sieve 15, a fine mesh sieve 20 allowing air to pass through but causing particles carried by the air stream to fall down the inclined plane 21 to the outlet 19. The seed passes to a sieve 22, which is cleaned by vibrating elements 23, large seed being carried to the exit 24, and seed which passes through to the sieve 25 being cleaned by brushes 26 and moved to the exit 27 where it may be discharged at 50 by operation of a valve 49 or transferred via a shoot 48 to the rotating sorting drum 36. The frame 32 for the brushes is slidable on rails 31 in the sieve box 7 and is carried by a rod 33 pivoted to the machine frame at 34. The drum 36 contains a trough 37 and reciprocates in opposition to the movement of the sieve box, the drum being supported on a shaft 38 which is secured at one end to a lever 39 pivoted to the machine frame, and at the other end to a double-armed lever 40 pivoted at 41 to the machine frame, and connected to a link 42 which is pivotally connected to the sieve box. The other end of the sieve box is supported by springy members 54. An eccentric 44 through the rod 30 reciprocates the sieve box, and through the levers 42, 40 reciprocates the drum 36, the masses of the sleve box and sorting drum being so arranged that vibration on the machine frame is minimized. Material falling into the trough 37 due to the rotation of the drum is passed to the exit 45, and material remaining in the drum passes along to the exit 46.

Inventor: CLIFT FREDERIC HOLLOCOOMBE
IPC: G01P1/10
Filed: 1916-09-13
Abstract: 111,308. Clift, F. H. Sept. 13, 1916. Pitot-tube apparatus.- Relates to air-speed indicators of the kind in which a pressure gauge is actuated by the air passing through a Pitot tube, and consists in arranging for an audible signal to be given when the speed of the aircraft falls below a predetermined rate. The pressure diaphragm b carries a boss h which, at a predetermined pressure, contacts with a spring finger e and forces the contact point e<1> away from a second point m<1> carried by the finger m and so breaks an electric circuit passing by way of the terminals f, f<1>, through a buzzer. Normally, when the aircraft is in flight, the circuit is broken, but when the speed falls too low, the buzzer gives an alarm. By means of a screw n, pinion o and wheel r fitted with an indicator t, the alarm can be set to any desired speed. The diaphragm b may operate a visual speed indicator also. The ends of the pressure and static tubes c<1>, d<1> are located in the slipstream of the propeller.

Title: Automatic hardness testing device
IPC: G01N3/44
Filed: 1950-05-24
Abstract: 698,413. Testing hardness of materials. REICHERTER, G. May 24, 1950 [May 30, 1949], No. 13059/50. Class 106 (ii). An automatic Rockwell testing device comprises means for holding the pointer of the dial gauge in deflected position indicating the hardness of a piece just tested until the initial stage of the following test. A frame 1 has fixed thereto a minor load spring 19 and a major load spring 20, and provides seatings for a test box 2 and the head 15 of a test rod 3 when they are inoperative. The test rod 3 terminates in a penetrator 21 and carries an arm 7 supporting a dial gauge 8 whose plunger co-operates with an arm 5 which rests on a knife edge 6 fixed to the test rod 3 and is pivoted to a plunger 4 sliding in the test box 2 to which the plunger 4 is frictionally coupled by a locking member 13 urged by a spring 16 when the spring 16 is free of a sliding block 17 which co-operates with a stop 22 in the frame 1. Initially, a wedge 11 sliding on the arm 5 is urged by a spring 12 to maintain the relative positions of the arms 5 and 7 to hold the pointer deflection of the previous test, as a screw 24 lifts a test piece 25, the test piece lifts the test box 2 against a spring 23 and to a lesser extent the test rod 3 due to penetration under the influence of the minor load spring 19, a bell-crank lever 9 pivoted to the arm 7 engages a stop 10 in the frame 1 and pushes the wedge 11 free of the arm 7 so that the spring 14 urging the plunger 4 down causes the arm 5 to lift the dial plunger and set the dial gauge to read 100, further lifting of the test box 2 carries the spring 16 clear of the slide 17 which is held by the stop 22 and the spring 16 locks the plunger 4 to the test box 2, the dial still reading 100. Further lifting of the test piece 25 brings the test rod 3 into contact with the major load spring 20 and under its influence relative movement of the arms 5, 7 due to further penetration causes movement of the dial indicator. Lowering the test piece 25 removes the major load and while the minor load is retained the pointer moves back to indicate the hardness of the test piece, further lowering releases the bell-crank lever 9 from the stop 10 and the wedge 11 locks the arms 5 and 7 to hold the dial deflection, final lowering causes the slide 17 to unlock the plunger 4 and the test box 2 and test rod 3 to be reseated.

Title: Improvements relating to the treatment of effluent liquors
Inventor: NICKLIN THOMAS
IPC: C10K1/00
Filed: 1956-04-30
Abstract: In a process for treating ammoniacal effluent liquors from coal carbonization processes, thus producing waste liquors which have a reduced tendency to absorb oxygen and which are thus more acceptable to sewage works, the liquor is first steam-distilled to remove free NH3, H2S and CO2 and then treated with lime to remove fixed NH3 and convert phenols, thiocyanates and thiosulphates to calcium salts. The thus treated liquor is then decanted from precipitated solids, neutralized with an acid forming an insoluble calcium salt to liberate phenols from solution and filtered to remove the precipitated calcium salt, the filtrate being freed from phenols by solvent extraction, e.g. with methyl isobutyl ketone and passed through carbon filters to remove residual organic compounds.  The filtrate from the carbon filters may be further treated by chlorination. The treatment with lime may be effected in a lower part of the still used for distilling off the free NH3 and the liquor from the lime treatment is preferably acidified by passing CO2 through it.
