[Classes 35 and 38 (ii)] [Also in Group XXII] Sheets for transformer cores, dynamos, &c. are made from steel containing more than 5 per cent and not more than 7 per cent silicon, by casting an ingot, transferring it, while several hundred degrees above room temperature, e.g. 600‹ C., to a furnace and heating (or soaking it for about 4-6 hours) to 1200 to 1300‹ C. and rolling first into bars with reheating for 4-6 hours at 1000 to 1100‹ C. and then rolling into sheets which are doubled and interleaved with softer sheets, e.g. of mild steel containing 3 per cent selenium and heated to not less than 325‹ C., and pack rolled to within a predetermined percentage, 12 per cent, of the final thickness and then finishing by rolling at a lower temperature, e.g. about 850-900‹ C. or, to within 8 per cent of the final thickness and finish rolling at 700 to 760‹ C. The ingot may be transferred to the furnace as soon as it has become solid. The pack of sheets are sheared and separated immediately after the final pass preferably at 200‹ C. or before it drops to 95‹C. A sheet so made and containing from 6 to 6À5 per cent silicon is said to result in minimum noise when used for transformer cores. Specification 380,387, [Group XXII], is referred to.

Filed: 1957-07-22
Abstract: 802,866. Agricultural implements. SMITHBURN, G. E. July 22, 1957, No. 23100/57. Class 6(1). A rotary cultivator comprising cultivating blades 12 mounted in front of a pair of landwheels 17 is provided with an adjustable drag stake 19 providing with the blades 12 an initial support for the machine with the wheels 17, which are freely rotatable, clear of the ground. The stake 19 can be adjusted to determine the depth of cultivation of the blades 12. As shown in Fig. 1, no forward motion occurs until the blades have dug to the depth for which the stake is set. When this occurs the wheels will contact the ground and the machine will move forward until the wheels are clear of the ground when the blades will commence digging again. A motor 18 drives the blades 12 by means of a belt and pulley drive 83 and a vertical shaft mounted in a casing 26. A jockey pulley 86 acts as a clutch and is moved by a handle 92. The wheels 17 are vertically adjustable by means of bolts 42 engaging in holes 41 in wheel supporting members 36, Fig. 2 (not shown). The stake 19 is adjustably mounted in a bracket 54 adjustably carried by an arm 53 pivoted in the machine.

Title: Numerical control system for centre lathes
IPC: G05B19/18
Filed: 1972-05-17
Abstract: 1388769 Numerical control of machine tools ING C OLIVETTI & C SpA 17 May 1972 [18 May 1971] 23258/72 Heading G3N In a numerical control system for a lathe, discrete signals representing the transverse position of the lathe tool are used to produce a continuous transverse position signal. The ratio between a desired cutting rate signal and the continuous transverse position signal is calculated and used to control a servomotor which regulates the speed of rotation of the lathe mandrel. As shown, a punched tape reader 26 reads discrete positional data X 2 , Z 2 , prescribed tool feedrate F in mm. per revolution, prescribed cutting rate per unit time S, and offsets P and D representing X and Z divergences from a standard tool. The positional data are passed to an interpolator 96 of the type described in Specification 1154761 together with the feedrate signal F, converted into a mm. per unit time signal by multiplication by the angular speed of the mandrel supplied by a sensor 92 through a frequency divider 91, using a clock controlled accumulator 88. The resulting continuous position signals X' n , Z' n  are passed through D-to-A converters 102, 104 to lathe slide servos 110, 112. The X position signal X' n , after allowing for the offset P, is fed to a flip-flop register 122 to convert it to parallel digital form for use in a dividerconverter circuit 126. Other inputs in similar form are derived from the cutting rate data S and the gear ratio G between a servomotor and the mandrel. The circuit 126 includes variable gain operational amplifiers, Fig. 3 (not shown) to form a signal N representing the ratio between the cutting rate S and the X position signal allowing for the selected gear ratio G. The signal N is fed to the mandrel servomotor. Manual adjustments 72, 74, 132 are provided for the offsets P, D and cutting rate S, respectively. The frequency divider 91 may also be adjusted.

Title: Process for the production of ª--cyan-ª--alkyl-ª--phenyl acrylic esters
IPC: C07C255/34
Filed: 1960-07-04
Abstract: a -cyano-b -alkyl-b -phenyl acrylic acid esters are prepared by reacting an N-alkyl substituted alkyl phenyl ketimine with a cyanoacetic acid ester in the presence of at least the stoichiometric amount of acid.  The ketimine may be first prepared by reacting an alkyl phenyl ketone, in which the ring may be substituted e.g. by alkyl or alkoxy groups, with a primary alkylamine and the so-obtained ketimine reacted with the cyano ester optionally in the presence of an organic solvent.  The acid may be organic or inorganic and acetic acid is preferably used. In examples ketimines obtained from cyclohexylamine and acetophenone, p-methoxyacetophenone and propiophenone are reacted with methyl and nonyl cyanoacetates to give the corresponding substituted acrylates.
