Abstract: 1,237,319. Selective punching apparatus. MOHAWK INDUSTRIAL LABORATORIES Inc. 4 Nov., 1969 [1 April, 1969], No. 54028/69. Heading B4B. [Also in Division G4] In apparatus for selecting cards from a stack in which selector bars co-operate with coded notches on one edge of the cards, the selector bars are also used to control the operation of punches for selectively notching the edges of new cards. First embodiment, Fig. 3.-Keyboard-actuated solenoids 61A set respective selector bars 29A by moving them longitudinally so that recesses 60 no longer lie over lift bars 64 and their right-hand ends lie under punches 140. A new card is inserted between guides 148 so that the edge to be notched enters recesses 142 between dies 141 and punches 140. The punches 140 may be operated by means of cams on a rotating shaft which raise bars 64 by way of pivoted levers (not shown). Alternatively, a solenoid 160 may be energized to raise bars 64 against punches 140. A further solenoid 152 is used to punch a notch in the opposite edge of the card. Second embodiment Fig. 16.-A nylon covered cable 207 is attached to a punch assembly 203 at one end, is wound several times round a motor driven polished pulley 209 and is attached to a fixed point at its other end. The cable 207 thus drives the punch assembly across the ends of selector bars 29 until a longitudinally moved bar 29 is reached. At this point the cable slips on pulley 209 and contacts are closed to energize a solenoid 212 which operates the punch plunger 215 by way of arm 213 and elongated lever 214. On completion of punch operation, solenoid 218 is energized to reset the selector bar 29 by means of a plunger 219 carried on assembly 203, and the cable 207 is then able to advance the assembly 203 to the next set selector bar 29.

Abstract: 1,216,000. Machine tool details; press control; stamping; extruding. SIEMENS A.G. 28 Nov., 1968 [28 Nov., 1967], No. 56600/68. Headings B3B, B3H, B3Q and B3P. In a milling, turning, planning, drawing, extrusion, moulding or press tool operation, the tool is moved up to the workpiece with a fast traverse, and when a value of spindle torque, or tool pressure, exceeds a threshold value, the rate of traverse is reduced. In a turning operation the work spindle 5 is rotated by an electric motor Mn, the tool-holder 7 is moved in the Z direction by a stepping motor Mz, and in the X direction by an electrohydraulic stepping motor Mx. The input to motor Mx is connected through a switch 10 with a voltage frequency converter 11, which receives its input from a threshold value device 12. Three means for supplying an input voltage to device 12 are shown, but only one of the means will be used in any one arrangement. The first means is a torque transducer 15 and amplifier 14, the second means is a piezoelectric crystal 16 against which the tool 8 is pressed, and an amplifier 18, and the third means is a resistor 17 connected into one of the supply leads to motor Mn. In operation, with transducer 15 in use, switch 10 is closed and tool 8 moves at a fast rate along line Z, until it contacts the work at point X 1 . The rise in torque is detected by transducer 15 and causes the response threshold E1 of device 12 to be exceeded, thus reducing its output voltage. A pulse sequence of reduced frequency is supplied to motor M X  and the tool moves at a slower cutting rate. At point X 3  the torque is reduced, the voltage output from device 12 is increased, and the tool feed rate is increased until it reaches point X 4 . To avoid tool fracture with an excessive initial setting, a second threshold valve device 19 can be acted on by one of the devices 15, 16 or 17 and this has the effect of retracting the tool in the Z direction, or slowing down the movement in the X direction. Fig. 2 (not shown), describes a construction of the device 12.

Heading C5E. Dimethyl styrenes are produced from corresponding xylenes by reaction with ethylene and oxygen in the presence of at least one lower aliphatic carboxylate of palladium, e.g. the acetate, propionate or monochloroacetate. A saturated aliphatic acid may also be present, e.g. acetic, propionic or butyric. The palladium carboxylate may be used as such, in which case it acts as a reactant, or it may be supported on a porous carrier, in which case it acts as a catalyst. Suitable carriers are silica, alumina, silicaalumina, boria and active carbon. The catalyst may be promoted with an oxide or lower carboxylate of Cu, Ag, Pb, Cr, Mo, Mn, Fe or Tl. The catalyst may be conditioned by a basic nitrogen-containing organic compound, suitably present during deposition of the active components on the carrier, typical N-compounds being ethylamine, aniline, quinoline, pyridine acetonitrile, and benzonitrile. Aqueous ammonia may be used for the same purpose. The additional presence of a small amount of triphenyl phosphine prevents a decrease in catalyst selectivity during reaction. It is stated that when the catalyst is promoted with an oxide or lower carboxylate of thallium, optionally together with another of the promoters referred to above, p-xylene reacts only slightly or not at all. This phenomenon may be applied to the separation of p-xylene from the other xylenes.
