Abstract: 1,231,101. Electric calculators; meters. ENGLISH ELECTRIC CO. Ltd. 21 Feb., 1969 [21 Feb., 1968], No. 8411/68. Heading G4A. A digital circuit continuously calculates KVA demand (Z) from pulsed KWH and KVArH inputs (R and W) from the relationship shown in the curve of Fig. 3. Pulse inputs sets bi-stable T1 or T2 which are scanned alternately by bi-stable S1, any stored pulse setting a monostable Z1 to produce a +ve pulse A, while a voltage is produced at S1 which is 0 or +ve depending on whether the detected pulse is at R or W. A timer X1 produces phase-opposed square waves X 1 , X<SP>1</SP> 1  of eight times the frequency of Z 1  and S 1 . The pulses Z 1  are applied to a register B1-4 counting up to 16. Pulses Z 1 , X 1 , X<SP>1</SP> 1 , S 1  are applied in combinations to gates 15-18 to produce bunches of 8 pulses each. Gates 16-18 produce interleaved sets of 8 pulses each time the store W operates, to feed a reversible register A1-6 which counts forward as far as 64 and is then reversed by bistable A7 until it reaches zero again, corresponding to the left and right halves of the curve in Fig. 3. Register A1-6 resets when register B1-4 reaches full capacity. A logic system 35 produces an output which is fed to AND gates 36, 37 together with forward or reverse control from bi-stable A7 and the outputs from gates 16-18. OR gate 30 and EXCLUSIVE OR gate 25 combine to give a true or false output representing electronic subtraction of Z from 128, an inhibit input from 33 ensuring zero output between pulses. The resultant pulses feed a stepping motor 27 to drive a KVA demand indicator 28.

The locking means comprise detents 33, 38 which, in their locking positions (as shown) are retained in engagement with respective recesses 31, 37 in the shank 19 by retainer elements 42, 45. The latter are spring-urged to their retaining positions, but are longitudinally slidable so as to allow release of the detents into respective recesses 80, 81 of the elements 42, 45. The latter are slidable to their release positions upon rotation of an outer sleeve 71. This is secured to a cam member 63 which, when rotated relative to the chuck body 15, brings its cam slopes into engagement with follower rollers on a carrier 44 thus causing the latter to shift axially to move retainer elements 42, 45. Rotation of sleeve 71 can be effected while the machine spindle S is rotating. During axial shift of carrier 44, the latter abuts the rear of an ejector 83 and causes the forward portion of this to abut a flange 29 on the tool adapter to eject the same. The carrier 44 is releasably locked in its forward release position. It is released from this position upon insertion of another adapter 20 into the socket since the ejector 83 then acts as a trip which releases the carrier 44 when a flange 29 abuts the ejector forward portion. The adapter 20 has a ring 27 for grasping, and jaws 24 actuable by rotation of nut 25. As shown, the chuck has a shank 17 received in spindle S, but in a modification it is integral with the spindle.

In the machine described, a pair of the foil supply rollers 27, Fig. 1, is carried in frames 25 adjustably mounted on a beam 36 of the machine frame 12. The cutters 17 together with their motors 16 are adjustably mounted on a beam 13 of frame 12, and the workpiece supports 41 are adjustably mounted on beams 42 which are mounted for reciprocating movement on the frame 12. In operation of the machine, a workpiece 10, Fig. 5, such as a furniture panel, is placed on the supports 41 and held in position by suction devices. The beams 42 are then advanced so that the leading edge of the workpiece engages a projecting portion of the adhesive foil 26 which is supported between rollers 28, 29 on the frame 25. As the workpiece is advanced the foil 26 is adhered to one of its faces by the roller 28. When the foil extends across the whole width of the workpiece the latter operates a limit switch which causes the cutter blade 33 to sever the foil. The workpiece passes to a cutter 17 where a V-groove is cut opposite the foil. The groove may extend partially or wholly through the workpiece thickness. The walls of the groove may be subsequently glued and the workpiece folded to form, e.g. a furniture body. The machine may include drilling devices 24 adjustably mounted on the frame 12.
