Abstract: 927,218. Pharmaceutical beads and apparatus and methods for preparing the same. C. E. FISHER, and C. H. WILSON. Jan. 25, 1960 [Jan. 30, 1959], No. 2565/60. Class 81 (1). [Also in Group V] Substantially dry spherical pharmaceutical beads are made by directing preferably under pressure and through an orifice, a fine continuous stream of a composition comprising a sol of a congealable material e.g. gelatin, zein or carbowax and a pharmaceutical material, the temperature of said composition being above the congealing temperature of the sol, into a body of an immiscible liquid for said composition at a temperature below the congealing temperature of the sol, the body of the immiscible liquid moving transversely relative to the direction of movement of the stream of the composition and the depth and spread of the body of immiscible liquid being such that successive spherical beads are formed of substantially uniform diameter without interference of one bead with the other. An apparatus for making said beads comprises a reservoir 10 of congealable material containing said pharmaceutical material connected to a chamber 12. A plurality of orifices 14 are provided in chamber 12. Air under pressure in chamber 12 forces the sol through the orifices 14 into the immiscible liquid provided by a pump 16 from a supply 17 said liquid being directed over a trough 18 in a layer below the orifices, said layer being of a sufficient depth to prevent the beads formed from striking the trough. Heating coil 19 maintains the sol above its congealing temperature in reservoir 12. Cooling means 20 maintains the immiscible liquid below the congealing temperature of the sol. The beads formed range in size from 10-80 mesh U.S. standard and after formation are washed in a solvent e.g. naphtha or carbon tetrachloride and dried. The sol may also contain plasticizing agents e.g. sorbitol and substances reducing solubility e.g. for a gelatin sol, aldehydes such as formaldehyde, vanellin benzaldehyde or phenol. The beads may also be tanned. Specified pharmaceutical materials are D-amphetamine sulphate, Vitamin B12, Riboflavin, Thiamine hydrochloride, sulphaguanadine, D - amphetamine. Other constituents of the sol include isopropyl alcohol and flavouring agents. The spherical beads formed may be mixed with excipients e.g. lactose and magnesium stearate and compressed into tablets. The beads may also be coated with carbowax, shellac starch paste, glucose or acacia dried and compressed or may be enteric coated.

[Class 146 (iii).] A pencil holder comprises an open leadguiding tube 2 surrounded by an internally racked feeding-tube 3 angularly and longitudinally movable in the outer case 1 and normally pressed away from the point by a spring 4, and' a pusher 6 slidable in the tube 2 and provided with a resilient tooth engaging with the teeth of the tube 3, but adapted to be disengaged and pressed into the tube 3 when it is rotated in the case. The tube 2 is secured in the case 1, which is preferably formed of two sections secured together, and is provided with a slot through which the tooth on the pusher 6 passes into engagement with the teeth of the tube 3. The teeth on the tube 3 are of arcuate section, so that on rotation of the tube, the tooth on the pusher is brought into engagement with the untoothed part of the tube. The tube is formed with an external flange 10 engaged by the spring 4, which is enclosed by a cap 5 on the end of the casing. In use, the lead and pusher are inserted from the rear end into the tube 2, and are propelled by reciprocation of the tube 3. By turning the tube 3, the pusher is disengaged from the teeth, and the lead can then be pushed back into the tube 2. In a modification, a bayonet-slot connection between the cap 5 and tube 3 prevents the tube from being pushed in when the pusher is disengaged from the rack.

When paraffin is used, petrol may be used for starting. Compressed air is supplied by a pipe 4 to the interior of the jet nozzle, and issues through a restricted orifice into a mixing-chamber 25, where it meets the liquid fuel, which is supplied under pressure by a pipe 19. The mixture issues into a chamber 28 through an orifice 26 slightly larger than the orifice 3. Additional air is supplied to the chamber 28 through a hit-and-miss valve 30. The inner member. 1 of the nozzle is adjustable in its sleeve 5 to adjust the fuel opening into the cham. ber 25. When paraffin is used, it is supplied through the pipe 19 and petrol for starting through a pipe 20, control being effected by a three-way cock 9. When the engine has been running for some time, the cock 9 is automatically operated to shut off the petrol and connect the paraffin supply to the nozzle. The cock 9 is controlled by a rod 11 held in one of two positions by a spring-loaded lever 38 adapted to engage with notches 41, 42. The rod 11 is acted on by a spring 43 tending to hold it in the position shown. When petrol is being supplied to the jet, the lever 38 is in notch 42, and, as the engine-speed rises, so increasing the suction in the chamber 28, a piston or diaphragm 33 is acted upon to withdraw the lever 38 and so allow the spring 43 to shut off the petrol and open up the paraffin supply. Alternatively, the engine governor may control the lever 38.
