[Also in Divisions G4, H3 and H4] The output 12 from a stabilized voltage source is fed back over network 93 to a transistor T13 where it is compared with a reference voltage supplied by Zener diode Z2, the difference voltage serving to pulse-width-modulate a free-running pulse generator (see Division H3-H5) comprising transistors T14, T15, T16 and feedback circuit 17. The transistor 16 consequently supplies pulses of current from input 102 to a smoothing network comprising inductor 105 and capacitor 106, the duration of the pulses being controlled so as to maintain the output at terminal 12 equal to the reference voltage supplied by Zener diode Z2. Zener diode Z2 is supplied from a stabilized source including Zener diode Z3. Diode D12 switches on when transistor T16 switches off to maintain current flow in inductor 105.

Abstract: 815,706. Testing hollow-ware for leaks. CANADIAN INDUSTRIES Ltd. Oct. 4, 1957 [Oct. 11, 1956], No. 31134/57. Class 106 (2). A method of testing tubes 14, closed at one end, for pin holes or cracks comprises applying partial vacuum to the tubes by lowering a mercury-filled . container, and operating, a sorting mechanism according to whether or not a circuit formed in part by the mercury is broken. Tubes 14 are fed by means not shown to pockets 12 on a rotatable plate 1. Each pocket 12 has a sealing ring 13 and a passage 7 connecting it to a tube 8 inside a cup 3 containing mercury. The tubes 8 are fixed to the plate 1 but the cups 3 move vertically under the influence of a fixed cam 5 whilst rotating with the plate 1. When the cup 3 is at its lowest position, a partial vacuum is set up in the tube 14 being tested and if the tube is free from pin holes or cracks, contact is maintained by the mercury between electric leads 10, 11. If the tube 14 is faulty, the mercury in tube 8 falls and contact is broken. The breaking of the circuit causes electro-mechanical means (not shown) to pull the faulty tube from the pocket 12 at one point, but if the circuit is not broken, the tube passes to a further distribution point.

Abstract: 692,955. Tape dispensers. MINNESOTA MINING & MANUFACTURING CO. Dec. 27, 1950 [Feb. 4, 1950], No. 31375/50. Class 18. Pressure sensitive adhesive tape is delivered from a dispenser by an endless belt 30 mounted on pulleys 25, 27, a spring loaded pulley 31 pressing the tape into adhesive contact with the belt. The outer surface of the belt is longitudinally divided so that as the belt passes round the outer pulley 27 the segments of the belt are spread apart thereby releasing themselves from contact with the tape which continues out through an aperture 21 in the casing of the dispenser. A cutter 19 may be positioned near the aperture for severing the tape and a spring plate 22 may serve to clear the tape from the cutter after a. length has been severed. The belt may comprise a continuous spiral spring and the pulley 31 may be shaped to conform the tape to the circular shape of the belt, curving of the tape in this manner adding rigidity to it and further facilitating the separation between the tape and belt when the belt commences to pass round the pulley 27. Alternatively the belt may be made from flexible material the outer surface of which is longitudinally divided. The outer surface of the belt may be convex or recessed, and the pulley 31 may be correspondingly shaped to conform the tape to the shape of the pulley. A finger operated lever 36 having a chain driving a sprocket connected to the pulley 27 serves for advancing the tape.
