Abstract: 484,752. Delivery apparatus for printing-machines. GOSS FOSTER, Ltd. April 19, 1937, No. 11153. Convention date, April 20, 1936. [Class 100 (i)] In delivery apparatus for newspaper-printing machines, means are provided whereby a choke between the delivery belt 23 and the stripper 28 causes the prevention of papers passing from the folding-off rollers 3, 4 to the rotary fly 9. For this purpose, the portion of the belt 23 adjacent to the stripper 28 is supported by a roller or rollers 33 carried by arms 34 on a shaft 35 having a segmental gear 37 meshing with a worm 42 fixed to a spindle 43 slidable in bearings 44, 45 against the action of a spring 48, so that the roller 33 can yield if a choke occurs between the belt 23 and the stripper 28. Movement of the spindle 43 caused by such yielding operates a lever 61 connected to the spindle 43 by a pin-andslot device 55, and the end of the lever is formed with a guide 62 which, in the displaced position of the lever, diverts the papers away from the fly 9. Adjustment of the normal position of the roller 33 can be effected through the gearing 37, 42 by rotating the spindle 43, and this position is not effected by the yielding of the roller.

The inlets 12 extend over only a small part of the area of the top of the heat exchanger passages 17, 19, the remaining area forming a free outlet 14. The burner may be replaced by an electric element, and catalytic material may be arranged in the combustion chamber 20. The flow of gases may be from a central inlet to the annular passages, the burnt gases flowing up the central baffle. The walls of the concentric passageways may be corrugated to provide an extended contact surface.

Title: Improvements in and relating to lifting tackle
IPC: B66D3/16
Filed: 1919-05-07
Abstract: 142,302. Barnsley, P. G., and Barnsley & Sons, J. May 7, 1919. Self-sustaining gear for lifting-tackle is shown as applied to a pulley-block. The hand-wheel k is loose on its shaft e and, in hoisting, drives the shaft by the engagement of a lug r on the outer side of the hub with a lug s on a sleeve s' keyed on the shaft. When the lugs r, s are engaged, a dog q on the inner side of the wheel is disengaged from a lug p on a sleeve engaging a screwed part of the shaft and connected to the sleeve by a lost-motion spring connexion n. The spring connexion keeps the sleeve j contacting with a friction disk v in a recess in the bearing h, so that when the pull is removed from the hand-wheel, the shaft e tends to rotate backwards and presses the screwed sleeve against the friction disk and the collar t on the shaft against the bearing h, and so sustains the load. In lowering, the dog q on the hand-wheel engages the dog p on the screwed sleeve, and so rotates the sleeve on the screwed shaft and releases the brake. In a modification, an anchored ring is arranged in the recess in the bearing, with friction disks on both sides of it.

A suitable apparatus comprises a kettle 1, capacity preferably 100 gallons or over, which is heated from below by a firebox 10.  The sides and top of the vessel are also heated by electrical heating units 11 and 13, or by means of steam coils, so that condensation of vapours, such as glycerine, is prevented.  An outlet 18 is provided for such vapours.  A stirring device 15 is provided, which has a turbine-like blade, whereby the foam is sucked down to the bottom of the kettle and then forced out radially, as shown by the arrows 16.  The material is removed by suction applied to the outlet pipe 19, inert gas preferably being introduced to follow the liquid.  The treatment of copals and the formation of copal esters is referred to.  Specification 319,651, [Class 1 (i)], is referred to.

Class 108(3) In a constant force spring support device, the load is supported on a tube 7 pivoted to arms 1, 2, at 6. Arms 1, 2 are pivoted to a frame 3 at 4, 5. Helical springs 8, 9 provide the load supporting force. A compensating spring 10 comes into operation when tube 7 has descended far enough, under the appliad load, for a shoulder 13 to abut the top of the spring 10. The spring 10 may be housed inside the tube 10. In this case the top of the spring 10 is held against a fixed plug in the upper end of the tube 7 by a pair of pins which abut the lower end of the spring and slide in longitudinal slots in the tube. At a predetermined point in the downward travel of the tube 7 the pins abut fixed stops on the frame 3, thus compressing the compensating spring as the tube 7 continues its downward movement.

Radio-active ions are separated from solution by passing the solution through a filter on which is a sparingly soluble salt of a non- radio-active isotope of the radio-active element to be separated. Rapid ion exchange takes place between the solution and the solid material and radio-active ions accumulate in the solid. A membrane filter may be used and the solution passed through at 1-100 mls/ cm<SP>2</SP>/min. Several filters may be arranged in a column. In an example Ba 140 ions are removed from solution by filtering through inactive BaSO 4 . The process is useful for decontaminating radio-active waste water solution and for selective separation of radio-active ions.

Abstract: The invention comprises pyridinium salts of the formula <FORM:0742673/IV(a)/1> where R is a keto or hydroxy substituent, and X is a halide or aromatic sulphonic acid anion.  The compounds are prepared by dissolving cortisone or hydrocortisone in pyridine and adding thereto an aromatic sulphonyl halide, e.g. the sulphonyl chlorides or bromides of benzene, p-toluene or a - or b -naphthalene, thereby obtaining a mixture of halide and aromatic sulphonic acid salts, from which the halide salts are separated by washing the solid product with acetone.  The sulphonic acid salts are isolated by concentrating the reaction mixture to dryness, triturating with acetone and finally subjecting the residue to fractional crystallization.  Examples describe the preparation of D 4-17a -hydroxy-3:11:20-triketo-pregnenyl - 21 - pyridinium p - toluene sulphonate and chloride, and D 4 - 11b  - 17a  - dihydroxy - 3:20 - diketo - pregnenyl - 21-pyridinium chloride from p-toluene sulphonyl chloride, pyridine and cortisone or hydrocortisone respectively.
