Abstract: 989,121. Stacking-machines; suction lifting devices. WOODFIELD BENNETT Ltd. April 25, 1961 [June 8, 1960; Feb. 1, 1961], Nos. 20220/60 and 3846/61. Headings B8C and B8H. A machine for stacking bricks &c. comprises a gripper head for picking up bricks from a conveyer and depositing them in prearranged patterns, the head being capable of rectilinear tilting and rotational movements under automatic programmed control. The programme is fed in by a punched tape scanned by feelers operating switches controlling stops and pneumatic valves. The gripper head 10 is suspended from a carriage 7 running on rails 6, Fig. 4. The rails 6 are mounted on a frame 5 capable of vertical movement along a post 3a forming part of a structure 3. The structure 3 runs along rails 1b Fig. 1, and its movements are controlled by solenoid operated stops 23a, 23b, mounted on rails 21. Similar stops 45, 65, Figs. 1, 6, control vertical movement of the frame 5 and horizontal movement of the carriage respectively. The movements are effected by pneumatic motors and further similar motors enable the head 10 to be rotated, tilted relative to horizontal about axes 10a and 12, Fig. 4, and to make slow limited vertical movement, the latter to control pick-up more precisely. The pick-up head operates by suction pads engaging each brick and vacuum to each pad may be subject to separate control so that desired numbers of bricks may be raised or released. Alternatively bricks advanced by a conveyer 91, Fig. 2, travel across rollers 103 to a stop 97, the rollers being mounted on a series of supports 104-107. The stop may be raised and lowered by linkage 90, 99, 101 and a motor 102, but additionally, the supports 104-106 may be lowered when solenoids 121- 123 are operated to connect their supporting linkage to the link 99. Bricks on the lowered supports are thus not picked up by the head. Pneumatic and electrical circuits are described. The gripper head 10, Figs. 1, 10, comprises a frame having partition bars 10b and flanges 10c, 10j, retaining plates 10f urged downwards by springs 10i. Each plate has a gasket 10e and vacuum tube 10h to form the brick engaging means. Specification 989,122 is referred to.

Convention date, March 18, 1931. Divided on 398,264. Drawings to Specification. [Class 29.] Apparatus elements located at different levels are cooled alternately by a closed-cycle condensing-evaporating heat transfer system having its parts in open gas and liquid communication and consisting of two limbs connected at their upper and lower ends, and a vessel containing additional medium connected only to the lower end of one limb. This vessel undergoes temperature variations to change the effective liquid column in one limb and thereby bring about the alternate cooling action. The invention is described with reference to the cooling of the condenser and generator-absorber of the refrigerating system set forth in Specification 386,475, in which also the operation of the heat transfer system is described, but is applicable to cooling purposes generally.

Title: Process for the manufacture of yellow ferric hydroxide
IPC: C01G49/06
Filed: 1928-07-12
Abstract: 320,409. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 12, 1928. Ferric hydroxide is obtained by oxidation at a temperature above 40‹ C. of a precipitate containing ferrous hydroxide or carbonate in the presence of a solution of a salt of a, trivalent metal or of a suspension of the hydroxide obtained from such a salt by the action of a base. When a ferric salt is present, treatment with an oxidising gas may be unnecessary. According to examples: a solution of ferrous sulphate at 90-95‹ C. is treated with sodium carbonate to precipitate the iron partially, a ferric chloride solution then added, and oxidation effected by air at 90-95‹ C.; oxidation is continued after a further addition of ferric chloride, sodium carbonate being slowly added to complete the precipitation as oxidation proceeds. The product is filtered, washed until neutral, and dried at 100‹ C. A mixed solution of ferrous sulphate and ferric chloride at 90‹ C. is treated with sodium carbonate to precipitate the iron partially, and the precipitate is oxidized by air. Precipitation is then completed with continued oxidation by slow addition of sodium carbonate. A solution of ferrous sulphate containing aluminium chloride is treated with sodium carbonate at 90‹ C. with continuous oxidation bv air. A mixed solution of ferrous sulphate and chloride and ferric chloride at 100‹ C. is precipitated with calcium hydroxide or slaked or burnt lime with continuous oxidation by air. In each case oxidation is continued until a full yellow shade is obtained.

Abstract: 1282674 Links DANA CORP 28 April 1970 [30 April 1969] 20450/70 Heading F2K [Also in Divisions E2 and F1] In a throttle linkage arranged between a maximum speed control unit (not shown) and a carburetter 16, Fig. 1, of an I.C. engine, a Bowden cable 20 is connected at one end to the speed control unit and, at its other end, has its sheath 22 fixed to one end of a tubular housing 28 and its core 26 fixed to a member 42 carried by a plastics sleeve 46 slidably mounted in the tubular housing. The member 42 is connected to throttle valve arm 18 by ball-andsocket means 63, via an axial slot in the wall of the tubular housing. A compression spring (56), Fig. 2 (not shown), arranged between member 42 and one end of the tubular housing biases the core 26 into an extended position. During engine operation below the set maximum speed, pedal-operated throttle actuating linkage 14 controls arm 18 in the conventional manner. However, at engine speeds above the set value, the speed control unit moves the core 26 relative to its sheath to thereby move the arm 18 in a speed-correcting direction.

Abstract: 241,669. Mills, L. D., and Crowe, T. B. Sept. 3, 1924. Alkali cyanides; hydrocyanic acid.- Cyanogen is recovered from solutions containing compounds thereof by acidifying the solution, passing it in a finely-divided state through a relatively large counter-current of air so as to remove the hydrogen cyanide from the solution, and bringing the hydrogen cyanide gas in contact with an alkali solution.' The solution containing the cyanogen compounds is transferred from a tank 9 at a constant level through a long subdivided chamber 12 containing rotating agitators 19 which throw the solution up into a stream of sulphur dioxide gas which is pumped through the upper part of the chamber. A pump 36 transfers the acidified solution to a disperser 35 where it flows downwards through a series of grids 42 meeting a countercurrent of air from a pump 45 and pipe 46. The air laden with hydrogen cyanide passes round a partition 38 and down a compartment 39 to a pipe 49 leading to an absorber 48 having grids through which an alkaline solution from a tank 55 is caused to trickle. The air deprived of its hydrogen cyanide is led back to the inlet pipe 59 of the pump 45. A second disperser 61 and a second absorber 62 are arranged in series with the first ones. Modifications with acidifying towers and an alternate arrangement of dispersers and absorbers are described.

Abstract: 256,403. Plumstead, A. E. Aug. 22, 1925. Uniting by fusion; angular bending.-In making or repairing plated structures such as gas-holders, tanks, boilers, &c. by electric arc or gas welding, the plates are first given a slight curvature, the edges then tack-welded and the parts finally welded; so that when contraction occurs after welding the effect of previously curving the plate is to reduce the curvature of the plate and strains in the structure are thus eliminated. The plate may be curved as indicated at D by heating the outer surface of the edges of the plate to red heat by an oxyacetylene or other gas flame, carbon arc, &c. and then allowing the plate to cool. Using a plate of # of an inch in thickness, the surface of the plate may be heated at B to a distance of about <3>/16 of an inch from the edges C.
