Abstract: 1,161,211. Copying lathes. ENFIELD, LONDON BOROUGH COUNCIL OF. 15 Aug., 1966 [15 May, 1965], No. 19510/65. Heading B3T. [Also in Division G3] An automatic machine tool, having a cutter or tool bit movable in at least two directions, has a position signal generator giving rise to a succession of digital signals representing successive positions of the tool bit in a first direction, a servo system controlling movement in a second direction, and a programme device providing pairs of signals the first signal of each pair representing a particular position in the first direction and the second signal representing, according to the programme selected, the setting in the second direction the tool shall take up under control of the servo-system, on reaching the position represented by the first signal of the pair as determined by the signal generator. A copying lathe is fitted with a motorized actuator 12, Fig. 2, for the copying stylus which is mounted on the rear of the lathe saddle by a plate 23. The actuator comprises a screw jack ram 21 driven by an electric motor 22 through gears 24, 25. The ram has a hardened tip 26 which engages the copying stylus. A digital position encoder 30 is coupled to the ram by a collet 34. The ram is manually set up by a knob 33. The programmed instructions on a punched tape 16, Fig. 1, for the machine tool include two parallel series of 12 bit binary number, one series (the X channel) representing successive incremental positions of the saddle relative to a datum, and the other series (Z channel) which are paired with the first series, representing the diameter to be machined. The X, Z instructions are read into two buffer stores, one acting as a memory 15 for the Z instruction and the other as a co-ordinator 17, comparing the X number with a digital position feedback from an encoder 41. At coincidence, the Z channel number is gated into a comparator 18 by a trigger signal from the coordinator 17. The comparator, through a V-scan decoder 19, in response to the output of the encoder 30, controls the motor 22 through a controller 20 to position the stylus 13, through the ram 21, to machine the desired radius. The motor has a constant field excitation and the armature current from the controller 20 is pulsed and has a variable mark-space ratio to provide a degree of digital velocity control as the required ram position is reached. It is stated the arrangement can be adopted for multipass operation, or point-to-point positioning as required for drilling machines and presses.

Title: Improvements in or relating to catalysers for the synthesis of alcohols
IPC: C07C31/04
Filed: 1927-07-25
Abstract: 275,600. Compagnie de Bethune. Aug. 6, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Methanol and other alcohols.-The synthesis of alcohols, particularly methanol, by the hydrogenation of carbon monoxide is performed with the use of catalysts comprising irreducible metallic oxides to which 2-10 per cent of nickel, its oxide or salts, has been added. Instead of irreducible oxides, the corresponding formates deposited upon a porous support, as described in Specification 274,492, may be employed; inert metals may also be present. The addition of the nickel renders the catalyst less susceptible to deterioration and permits of a reduction of the reaction temperature. According to the example, heated active carbon is immersed in a solution of zinc and chromium formates containing a little nickel formate, and the whole evaporated to dryness; methyl alcohol is obtained by passing a mixture of carbon monoxide, hydrogen, nitrogen and methane at 800 atmospheres pressure over this catalyst maintained at a temperature of 300‹ C.
