Patent GB-1187833-A (GB)
Title: Improvements in or relating to Ball Bearing Cages.
IPC: F16C33/38
Filed: 1967-04-04
Abstract: 1,187,833. Making ball race rings. FAFNIR BEARING CO. 4 April, 1967 [8 April, 1966] No. 15292/67. Heading B3A. [Also in Division F2] A cage 16, Figs. 4 and 6, for a ball bearing comprises a ring having a number of ballreceiving holes 18 therein and having an inwardly-directed finger 20 between adjacent holes. Each finger 20 has an axial dimension which is less than the axial dimension of the ring, has arcuate opposed surfaces 24 which engage and prevent balls 14 from escaping inwardly through the holes 18, and has lugs 22 with opposed part-spherical surfaces 26 which prevent the balls from escaping outwardly. The balls are inserted into the holes 18, being forced between the surfaces 24 of the fingers 20. In another embodiment a cage 30, Figs. 9 and 12, has ball-receiving holes 34 therein; balls 36 are prevented from escaping inwardly by means of pairs of fingers such as 40A, 40B having opposed part-spherical surfaces such as 44A and 44C. The balls are prevented from escaping outwardly by means of arcuate projections 46. In a modification a cage has arcuate projections 64, Fig. 14C, and has single fingers 58. In a method of making a cage for a ball bearing, a ring is formed with a number of spaced radial holes having a diameter which is less than the balls to be received therein. Inwardly extended fingers are formed between the holes and the finger and the holes are machined by means of a cam-actuated recessing tool (not shown). The tooling process increases the size of the holes in accordance with the size of the balls to be received therein, forms ball-retaining seats on the fingers, and forms ball-restraining means. The latter may be the part-spherical surfaces 26 of the lugs 22, Fig. 4, or may be the arcuate projections 46 in flanges 38, Fig. 12.

Patent GB-597158-A (GB)
Title: Improvements in or relating to therapeutic agents or compositions
IPC: A61K31/18
Filed: 1944-08-17
Abstract: A therapeutic agent or composition is obtained by heating a mixture of a "sulpha" drug and elementary iodine until the evolution of fumes of iodine ceases.  The sulpha drugs consist of sulphanilamide and its derivatives such as sulphapyridine, sulphathiazole, sulphapyrazine, sulphaguanidine and sulphadiazine, including their salts and substitution products such as sulphanilamide phosphate and sulpha-methyl-diazines.  The heating step may be effected at a temperature of 40-80 DEG  C., according to one example in the presence of alcohol.  The product of the heating step is preferably digested with alcohol or other solvent which will dissolve iodine or the sulpha drug containing adsorbed iodine, but is a poor solvent for the sulpha drug itself. The separated solution (fraction "A") is evaporated to dryness and treated with a selected solvent for free iodine such as petroleum ether to remove unadsorbed elementary iodine.  The undissolved extraction residue (fraction "B") is washed with alcohol or other solvent for free iodine.  Both fractions retain the gross physical and chemical characteristics of the sulpha drugs, but have enhanced antibacterial potency brought about by an obscure chemical change.  Fraction "A" contains adsorbed iodine. Fraction "B" is free from iodine.

Title: Improvements in or relating to platen printing presses
IPC: B41F1/28
Filed: 1935-06-29
Abstract: 463,542. Sheet-delivery apparatus. THOMPSON & SON, Ltd., T. C., and THOMPSON, F. S. June 29, 1935, No. 15840. [Classes 100 (i) and 100 (ii)] In a platen printing-press the sheets are delivered from the press after printing by a reciprocating gripper device which also oscillates about an axis parallel to its reciprocatory movements so as to move with the platen. The grippers 11 at their lower end have an extension 11<b> pivoted on a bush 12 slidable along a bar 13 extending axially from the pivotal shaft of the movable platen. A guide member 14 on the extension 11<b> engages a bar 15 fixed to and extending laterally from the platen so as to cause the grippers 11 to move with the platen. Reciprocation of the grippers to and from sheet receiving position is effected by an oscillating toothed sector 23 driving a pinion 22 on a shaft 21 carrying a crank 20 pivoted centrally to a link 19 itself pivoted at its upper end to a member 16 slidable on the bar 13 and on a bar 18 and having mounted therein the bush 12. A roller 19<a> on the bottom end of the link 19 is adapted to engage a guide 33 directly below the shaft 21 as the crank 20 approaches the vertical to cause the members 19, 20 to cross over one another and thus increase the travel of the slide 16 and grippers 11. The grippers 11 are opened and closed by means of a spring-controlled lever 35 carrying a roller 35<a> engaging a cam 34 mounted on the bar 13 and oscillated by a cranked-lever 38 mounted on the bar 18.

Abstract: 926,444. Crushing machines. N. LOVERDO. March 16, 1962 [May 4, 1961], No. 16138/61. Class 59. A crushing machine for use in the production of industrial diamond powders comprises a crushing member 2 pivoted to a base member 1, a reciprocable crushing member 14, means to connect the crushing members so that the crushing member 2 is tilted about its pivot 9 during a portion of the upward stroke of the crushing member 14, a feed hopper 3 attached to the member 2, and a receptacle 6 for receiving crushed material. Removable plates 5, 13 are arranged so that the lower one is recessed into the base assembly to form an adjustable crushing space and the hopper 3 is provided with a removable comb 8 so that only material of or below the optimum size is fed. A spring clip 11 secured one on each side of the member 2 by screws 10 has an inturned upper end portion 16 which displaceably engages a protuberance on the upper end of the member 14. When the member 14 is raised, it first moves relatively to the member 2 until the spring clips engage the protuberances, whereafter the member 2 is tilted until it reaches a stop 17 so that it no longer moves with the member 14 in its upward stroke. This tilting action serves to deliver material from the hopper 3 and discharge ground material into the receptacle 6. A knob 21, or alternatively an electromagnet, is provided so that the member 2 can be retained in its lowermost position when it is desirable that several crushing strokes should be applied to the same material. Several machines could be used in tandem so as to progressively reduce the size of the particles of material.
