Title: Process for the production of stable emulsions and suspensions
IPC: C09K23/00
Filed: 1931-06-01
Abstract: The process of the parent Specification, according to which oils, fats or waxes are formed into emulsions, with positively charged particles in an aqueous mixture of a protective colloid and an aluminium salt, is extended to the treatment of water-insoluble organic substances in general, except bituminous substances, and insoluble inorganic silicates, sulphates, and the like, with protective colloids in conjunction with reversing agents other than aluminium salts, including positively charged hydrosols such as that of aluminium hydroxide.  Examples refer to the emulsification of paraffin, neatsfoot oil, benzol, or trichlorethylene, with aqueous solutions of glue containing aluminium hydroxide sol, acetic acid, hydrochloric acid, copper sulphate, sugar of lead, ferric sulphate, or thorium nitrate.  A further example comprises 12 kg. of barium sulphate, 5 kg. glue, 1 litre of 30 per cent hydrochloric acid, and 82 litres of water. When using acid such a quantity is used as will render the pH of the colloid less than 4.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the addition of reversing agents to prepared concentrated emulsions or dispersions which are diluted before use.  This subject-matter does not appear in the Specification as accepted.

Abstract: 692,395. Rolling. PETERSON, E. T. July 6, 1951 [July 13, 1950], No. 16123/51. Class 83 (iv). In a cooling bed comprising two intermeshing sets of carry-over bars, relatively movable up and down and backward and forward, one end of the first set of bars is pivotally mounted, the opposite end of the second set is pivotally mounted, an eccentric is operatively connected to the other end of the second set, and a rocker, pivotally mounted intermediate its ends, is connected at one end to the eccentric and at the other end to the other end of the first set of bars. One set of carry over bars 20 is supported at its ends on beams 23, 24, and the other set 21 is supported at its ends on beams 25, 26, the beams being preferably sectionalized every 15 feet laterally of the bed. Rockers 50 pivoted at 51 each engage at one end 54 beneath an eccentric roller 48, Fig. 5, carried on a crank portion 34 of an eccentric electric motor-driven shaft 32, made up of sections joined by tubular connections 36 which allow of expansion or contraction, the crank portions 34 being connected to the beam 25 by eccentric straps 46, bolted at 61, 62, springs under the bolts 62 allowing of expansion and contraction. The other end of each rocker is pivotally connected to one end of an adjustable link 56 whose other end is pivotally connected to the beam 24. The beam 23 is pivotally mounted on foundations 31, and the beam 26 carries rollers 63, 63<SP>1</SP> supported on tracks 64, the rollers 631 at one end of each section of beam 26 being without flanges, to permit lateral movement on the track to allow for expansion and contraction. In operation, the set 20 pivots at one end on the beam 23 and moves up and down at the other end under the action of the shaft 32 and rockers 50, acting through the links 56. The set 21 moves up and down and back and forth at the end supported on the beam 25 under the action of the eccentric straps 46, and at the end supported by the beam 26, pivots about the rollers 63, 63<SP>1</SP> and also moves back and forth on the tracks 64. The cooling bed may be used with any combination of run-in table, pack-amiealing bed and run-out table, e.g. Fig. 1, shows a run-in table 67 having individual electric driving motors 68, lifting apron 70 and kick-off mechanism 71, and a run-out table comprising eccentrically operated shuffle bars 73, raised or depressed by levers 75, and run-out rolls 76. Other forms of known run-in tables appear in Figs. 2 and 3 (not shown).

Abstract: 852,876. Door operating appliances; sliding jaw clamps. KING, H. W. M. April 23, 1959 [May 22, 1958], No. 16494/58. Classes 44 and 65(1). In a pneumatically or hydraulically operated piston and cylinder device for moving a sliding door, the piston rod and cylinder being anchored one to the door and the other to a stationary part of the surrounding structure, the piston rod anchorage comprises a friction coupling which holds the piston rod during normal door-operating thrusts but allows it to become free from its anchorage if the door is subjected to a thrust exceeding a predetermined value. In the device illustrated the bullet-shaped nose 20 of the piston rod 12 is frictionally held by a clip or clamp comprising a fixed part 21 and a similar part 22 biased towards the first part by springs 23. Pilot release valves may be provided to control the exhaust of fluid from the cylinder as the door approaches the limit of its travel in either direction to produce an adjustable buffer effect, and similar valves may be provided to relieve the fluid pressure in the event of the door becoming obstructed.

Title: Improvements in or relating to chucks
IPC: B23B31/12
Filed: 1946-05-31
Abstract: 612,855. Chucks. ULVSUNDA VERKSTADER AKTIEBOLAG. May 31, 1946, No. 16588. Convention date, June 8, 1945. [Class 83 (iii)] A chuck is provided with an external holding sleeve which is axially displaced to subject a series of balls to radial pressure so that they engage a rotatable and axially movable member to effect opening of the jaws. Secured in the body 2 is a sleeve 8 provided at its upper end with two diametrically opposed radial recesses which accommodate the ends of the rectangular head of a screw 5 having a helix angle sufficiently steep, for instance nine degrees, to prevent it from being self-arresting. The screw engages a member 3 slidably housing the jaws 13 which are provided with grooves 19 (Fig. 4) to engage balls 18 mounted in lugs on an annular jaw holder 15. A thrust bearing 25 is interposed between the latter and the sleeve 8. The jaw holder has two conical surfaces 23, 24 providing a race for a series of balls 21 arranged in bores 22 in the body. Under the action of centrifugal force the balls enter a space 29 in the holding sleeve 26 which is displaceable on the body and provided with an oblique rolling race 30. To open the jaws the holding sleeve is raised, causing the race 30 to bear on the balls 21 and place them in engagement with the jaw holder which is thus rotated together with the member 3 at a speed higher than that of the body and the screw so that the member 3 is downwardly displaced to open the jaws. A slow opening movement is obtained due to the fact that the contact points of the balls on the jaw holder are radially nearer to the centre of the balls than the contact points on the race 30. The jaws are closed by retarding the member 3. Since the jaws and the screw do not move axially, a constant depth of insertion is provided for the tool.
