Title: Collet actuating mechanism
Inventor: PARSONS HUBERT JEPTHA
IPC: B23B31/20
Filed: 1962-10-22
Abstract: 955,406. Chucks; mandrels; sockets. HARDINGE BROS Inc. Oct. 22, 1962, No. 39823/62. Heading B3B. A collet actuating mechanism comprises a hollow spindle 12 within which is located a draw-tube 14 to which the collet is attached. Relative movement between the draw-tube and spindle to secure or release the collect is effected by a number of equally spaced screws 16 which co-operate with an annular internallythreaded sleeve 18 which is secured to the drawtube by a port 19. The heads of the screws are in the form of helical pinions 25 which engage a helical gear 27 which is attached to and movable with the draw-tube. The longitudinal movement of the gear 27, with the draw-tube 14, rotates the screws 26 urging them against a collar 22 secured to the spindle. A ball bearing with its inner race 30 secured to the gear 27 and its outer race attached to a hand lever 33 facilitates movement of the gear 27 and drawtube to effect gripping or releasing by the collet. The action of the screws in this device permits the retention of the collet in the open or closed position since axial pressure on the screws alone will not effect movement of the gear 27. Adjustment means is provided initially to set the draw-tube and spindle relative to each other and to accommodate workpieces which may differ in diameter. In an alternative embodiment the actuation of the mechanism is effected pneumatically, whereby a piston and cylinder assembly is formed around the gear and screws, the piston being adapted to co-operate with the ballbearing to effect axial movement of the gear and draw-tube when compressed air is emitted to either one side or the other of the piston.

Abstract: Pharmaceutical and like tablets comprise coated tablet core having a plurality of foundation sub-coats, an ink-receptive resinous coating of film-forming material containing a lubricative plasticizer on which is ink-printed indicia of a distinguishing colour, and an outer transparent coating over the said resinous coating and indicia. Suitable film-forming materials are shellac, epoxy resin and sandarac; suitable lubricative plasticizers (which reduce the brittleness of the resinous coating and also lubricate the coating so that the tablets may be readily fed into the printing machine) are high molecular weight fatty alcohols and glycerides of higher fatty acids and for use in the transparent outer coating there are mentioned carnauba wax and bees-wax.  The coating steps may be carried out by the conventional pan-coating method and the ink-printing may be applied before the resinous coating has completely dried, preferably using an ink which has the same resin base as the coating.  Specification 842,613 is referred to.

Abstract: 1,029,169. Carton erecting machines. SOMERVILLE INDUSTRIES Ltd. Oct. 6, 1964, No. 40694/64. Heading B5D. A machine for securing in position partitions in an egg carton, the carton being of the type shown in Fig. 8 partly erected, comprises feeding means for the folded blanks, gripping devices which grip the two side walls, actuating means for causing the gripping devices to spread out the folded blank and a plunger for interlocking the partitions with the carton walls. In one form the folded blanks are stored in a magazine 34 and removed singly by a pair of suction pads 44 which deliver each blank to rails 50. Kicker bars 53 push the blank beneath pairs of further suction pads 54, 60 which are then actuated to unfold the carton to the position shown in Fig. 8 when the partitions 12 orientate themselves with slots in the carton side walls. The plunger 74 then descends and forces the partitions into interlocking engagement with the side walls and continued downward movement of the plunger forces the carton down a shoot 76 thereby folding up the side walls. All the members so far described are actuated by various linkages actuated in the appropriate sequence by cams on a cam-shaft 90. The shaft 90 is driven by gears 94, 96 from a further shaft driven by a belt 98 from an electric motor and speed reducer combination. The suction to the pads 54, 60 is controlled by a vacuum switch 172 operated by a cam 170 on the shaft 90. Suction to the pads 44 is controlled by a switch 122 actuated by a detent 120. In another form, the plunger moves horizontally instead of vertically the carton being set up in a position turned at 90 degrees from that shown in Fig. 8. The magazine of this form of machine has a conveyer forming the lower wall, the conveyer being operated by a ratchet mechanism to advance another blank each time the plunger is actuated.

A rotary fan for internalcombustion engine cooling systems comprises a central rotary body 3, a plurality of blades 6, extending from the body, a stem 6a on each blade 6, a quickpitch screw-thread 7 or equivalent means whereby radial movement of the stem 6a will be accompanied by angular movement thereof, and a rubber or rubber-like member 12 of hollow form acting between the body 3 and the stem 6a for resisting both radial and angular movements. Bushes 4, mounted in the body 3, have screwthreads 7 which engage with complementary threads on the stems 6a. A head 10, on the inner end of the stem 6a, of square or similar crosssection, is secured to a plate 11 to which is bonded a cylindrical rubber member 12. The other end of the member 12 is bonded to a disc 13 which has claws 13a engaging in recesses 4a in the bush 4, to prevent relative angular movement between the disc and the bush. Thus radial and angular movement of the fan blades 6 is resisted by the member 12 and the blade pitch will decrease as the engine speed rises.
