Title: Lathe having variable speed spindle
Inventor: WISTI MORRIS DENNIS
IPC: B23Q5/34
Filed: 1969-10-28
Abstract: 1282788 Controlling spindle speeds STAR MACHINE & TOOL CO 28 Oct 1969 52796/69 Heading B3T In a lathe, particularly when used for facing operations, means is provided to maintain a constant predetermined cutting speed by controlling the speed of rotation of the workpiece in direct relationship to the diameter being turned. The lathe comprises a work spindle 14 connected by gearing 54, 56 to a drive shaft 52, a main motor 82 mounted on the cross-slide 32 and in driving connection with the shaft 52 by way of a belt 90, pulley 87 and a variable pulley 75. A further belt drive from the shaft 52 to a cross-slide feed gear-box 41 is provided, whereby in operation as the cross-slide moves, the distance between pulleys 75 and 87 changes which is compensated for by changes in diameter of the variable pulley, thereby effecting a change in speed of the work spindle as the cross-slide moves the cutting tool 49 across the face of the workpiece. In the embodiment described, in which the workpiece is a brake disc, a pair of cutting tools 49 are mounted in tool posts 46 in spaced relationship, whereby both sides of the workpiece are machined simultaneously.

Abstract: 1,209,546. Recording and playback. W. E. POSADAS. 11 Nov., 1968, No. 53221/68. Heading G5R. A strip is composed of two layers of materials having different physical (e.g. magnetic) properties, the interface between the two layers forming a hill-and-dale recording which may be read by external means responsive to the different physical properties of the two layers. As shown, two strips 1 of plastics material, each carrying an independent hill-and dale recording, are arranged face-to-face with the varying space between them filled with a ferromagnetic material 2. Flux from a magnet 3 passes through the ferromagnetic material 2 and the nearer recording is played back by means of a head comprising a core 5 with a projecting point 4 and a winding 6. Two heads may use a common core 5. The ends of the composite strip are joined to form a M÷bius loop so that both recordings may be played back in sequence by the same head. The strip is contained in a cassette (9, Fig. 5).

An alkali metal vapour dispenser comprises a container 1 provided with a slot 2 through its wall and containing a mixture of particles 3 including an alkali metal chromate, a reducing agent, and a proportion of very fine particles of a metal which can be at least partially sintered at temperatures below 600‹ C. and has a vapour pressure substantially lower than that of the alkali metal released when decomposition of the alkali metal chromate takes place. The sinterable metal may be Fe, Ni, Co or Ti. A getter material may be added to the mixture to prevent the evolution of O 2  and H 2 O during the reduction. The getter may be Zr or Zr alloy which acts also as a reducing agent. Alternatively the reducing agent may be Si.

In operation, 'valve 35 is opened and liquid fuel which is under pressure in chamber 25 is forced through. passage 33 into the conduit and passes into reaction chamber 13. Alternatively, reaction chamber 13 may initially contain a pressurised solution some of which is forced down the conduit to mix with a solid fuel component in chamber 25 when valve 35 is opened. The catalyst is so arranged in chamber 13 that as the fuel level rises in the chamber, the fuel comes into contact with a greater catalyst surface area. As the hydrogen pressure increases in chamber 13, fuel is forced back into chamlber 25. The rate of generation of hydrogen is thus dete:rmined by the rate of withdrawal of hydrogen through valve 21. The fuel may be an aqueous alkaline solution of sodium or potassium borohydride; the catalyst may be nickel, platinum, iridium, alumina.
