Title: Method of separating the fat, the ossein and the tricalcic phosphate of bones by means of aqueous solutions of sulphurous anhydride and of salts of sulphurous acid
IPC: C05B17/00
Filed: 1920-05-07
Abstract: Ossein is obtained by breaking up bones and treating them with a hot aqueous solution of sulphurous acid or its salts.  The calcium phosphate forms a soluble compound with the acid solution, while the fat contents become white and separate out on the surface, the ossein remaining at the bottom practically unaltered.ALSO:Bones are broken up, and heated with a hot aqueous solution of sulphurous acid or its salts.  The calcium phosphate forms a soluble compound with the acid solution, while the fat contents become white and separate out on the surface, the ossein remaining at the bottom practically unaltered. On adding calcium hydrate to the solution a crystalline precipitate of calcium phosphate is obtained, and calcium salts of sulphurous acid are formed which may be recovered and used again.ALSO:Calcium phosphate is obtained from broken bones by treatment with a hot aqueous solution of sulphurous acid or its salts.

Title: Improvements in paper feeding and guiding mechanism for typewriting machines
IPC: B41J13/10
Filed: 1926-05-19
Abstract: 276,078. Myers, L. C., and Royal Typewriter Co., Inc. May 19, 1926. Sheet and card feeding and guiding arrangements.-A bail carrying feedrollers is so mounted that the feedrollers can engage the platen at positions remote from or adjacent to the printing line for tho purpose of feeding sheets or cards respectively. A bail 3 carrying feed-rollers 1 is pivoted ou rocking arms 4 secured to a rod 7 which is mounted in recesses in the carriage A and is retained by yokes 9. Springs 11 connected to the bail and yokes retain the feed-rollers in engagement with the. platen. A finger-lemer 20 frictionally pivoted on one of the arms 4 and movable between stops 25, 26 is formed with shoulders 22, 23 co-operating with a stop 24 to determine the position of the feedrcller. When the shoulder 22 engages the stop the feed-rollers occupy the sheet-feeding position, and on pulling forward the bail and depressing the finger-lever the shoulder 23 engages the ston and the feed-rollers occupy the card-feeding position. When the feed-rollers are in either sheetfeeding or card-feeding position the bail can be pulled forward to release the feed-rollers, the movement being limited by contact of lugs on the rocking arms and a lug or roller 16<1> on the bail with the yokes and carriage respectively. On releasing the bail thq feed-rollers are, restored to their original position. When the feed-rollers are out of use the bail is turned back to the position shown in Fig. 5, the bail being retained in this position by the springs 11. When the bail is again depressed it is presented from moving forward with the arms 4 and thereby carrying the feed-rollers to the forward or released position, by means of a pivoted latch 27 having hooks 31, 32 co-operating with a pin 33 on the bail. The latch is pivoted on a rod D and has a lug 30 which is retained in contact with the carriage by a spring 29. When the arms 4 are in the position shown in Fig. 1 or Fig. 5, and the bail is depressed, the pin co-operates with the hooks 31 or 32 and constrains the bail to carry the feedrollers to sheet-feeding or card-feeding position respectively. When the dial is again turned back the pin clicks over one or both of the hooks.

Title: Improvements relating to electric cable joints
Inventor: PLODOWSKI RYSZARD
IPC: H02G15/24
Filed: 1967-03-20
Abstract: 1,221,651. Cable joints. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. and CENTRAL ELECTRICITY GENERATING BOARD. 20 March, 1968 [20 March, 1967], No. 13021/67. Heading H2E. In a cable joint wherein a system of passages is provided for the passage of insulating fluid through solid insulation surrounding the jointed cable ends, part of the passage system comprises a passage which is shaped so as to follow a non- cylindrical equipotential surface in the electric field which arises in use. As shown, a joint is made by stripping back lead sheath 12, copper tape 11, screening tape 10 and insulation 8 to reveal conductor 4 with oil duct 6. A steel mandrel 14, temporarily plugged, is pushed into conductor 4 and an aluminium ferrule 16 attached. Another cable is similarly prepared. Oil-impregnated rolls 18 are slipped over the insulation 8; the ferrules 16 are connected by an aluminium coupler 20; an insulating tube 22, which accommodates a stress ring 26, is slid over coupler 20; a stress core 48 is positioned at each end of tube 22; and on insulating tube 52 and a copper tube 86 sealed at 92 are slid over the assembly. These members define oil passages 32, 34, 36, 30, 38, 28, 72, 74, 76, 100, 102, 98. The passages 72, 76 follow an equipotential surface, preferably 35% (where the conductor potential is 100%). The surfaces of passages 38, 72, 76 are conductive; passages 72, 76 being electrically connected at 54 e.g. by aluminium spinnings, and passage 38 being connected to stress ring 26 at 40. Lead or copper wire 80 is soldered to sheath 12 at 84, wound over a conductive surface 63 on core 48, connected to a brass ring (not shown) in a recess 64 to provide an earth stress-core electrode. Members 22, 48, 52 are preferably silica-filled epoxy resin castings. As applied to a stop-feed joint (Figs. 2A, 2B, not shown), a solid aluminium coupler (20<SP>1</SP>) and a stress ring (26<SP>1</SP>) block oil flow through passages corresponding to 32, 36, 38. Radial oil passages (34) contain valves (122). The passage (76<SP>1</SP>) corresponding to passage 76 is blocked and split longitudinally, so that oil flows from a passage (72<SP>1</SP>) through the lower half of passage (76<SP>1</SP>) and back along the upper half thereof.

Abstract: 804,798. Screwing-up and unscrewing drill rods. JOY MANUFACTURING CO. May 6, 1955 [May 11, 1954], No. 13159/55. Class 83 (3). Mechanisms for making and breaking the joints of oil-well drill-pipe has jaws for gripping and rotating one pipe section, whilst a lower pipe section is held by other jaws. The holding jaws 40, Fig. 2, and rotating jaws 41 are carried by a built-up frame 13, 14 on a slide 5 which is horizontally and vertically adjustable on a pillar 7 by hydraulic cylinders 8, 9, the pillar being supported on the derrick floor 3 of the drill rig. Both sets of jaws consist of serrated grippers 27, Fig. 8, pivoted at 28 to floating links 26 and operated by links 31 connected to pins 32 slidable in slots 33 in jaw levers 34 pivoted on pins 35. The pins 32 are movable along slots 33 by hydraulic cylinders 91 to cause the jaws 27 to move to gripping position, and the levers 34 are swung about pivots 35 to grip the pipe 4 by rotation of a cam 53 acting on toggle links 61, Figs. 8 and 15. Springs 67 tend to open the jaws. The jaws and levers are laminated, as shown in Figs. 4 and 6. The pivots 35 are carried by a laminated yoke 43, Figs. 4 and 8, in which the cams 53 are rotatable, the cams being slidable along arcuate slots 54, Fig. 14, in the frame plates 13, 14. Hydraulic pistons 82, 85, Fig. 6, in cylinders pivoted at 77 to the frame, actuate links 84, 87, Figs. 6 and 8, connected to the pivots 35 of the jaws, to rock the jaws into and out of gripping engagement with the pipe sections, the lower cam 53 being held stationary by a link 50, Fig. 4, connected by a slot 51 to a pin 21 on frame 14, during this movement. After gripping the pipe sections, fluid is admitted to cylinders 76, Figs. 2 and 7, also pivoted at 77 and whose pistons are connected by links 74 to a yoke 71 integral with the upper cam 53, whereby the upper jaws 41 are rotated to break the joint between the pipe sections. A fluid circuit is described in which the supply is controlled by a set of manually-operable valves to actuate the cylinders in sequence to tighten up or unscrew a pipe joint.
