Title: Dispensing head for connection to a cartridge gas container
IPC: F24C3/14
Filed: 1973-11-12
Abstract: 1448463 Fluid - tight connector; valves APPLICATION DES GAZ 12 Nov 1973 [10 Nov 1972] 52490/73 Headings F2G and F2V  A gas dispensing head for connection to a compressed gas cartridge 11 has an elongate control member 25 slidable within a sleeve 20 and biased outwardly by a spring 19 which unseats a valve member 12 in the cartridge but which will not puncture a perforable type of cartridge if the head is erroneously connected to such a cartridge. In one embodiment, as shown, the lower part 25c of the member 25 also acts as a needle-type valve in deforming a square bore 21a in a resilient seal plug 21. An outlet tube 28 and the sleeve 20 are slidable under the action of a cam surface 22a on a piston 22 carried on the member 25. Before connection to the cartridge the member 25 is held retracted by a lug 26a in abutment with the rim 16a on a sleeve 16 in the main body of the head. When a control knob 26 on the member 25 is correctly orientated the lug 26a can pass through a notch 16b in the rim 16a and the spring 19 moves the member 25 and the inner assembly downwards. Continued rotation of the knob turns the cam surface 22a to allow the member 25 to emerge further through the plug 21 to unseat the cartridge valve and to control the gas flow through the bore 21a. In another arrangement the cam surface is on a stationary sleeve and is contacted by a pin (42) (Figs. 14, 15, not shown) on the control member. In a further arrangement the control member acts automatically under the spring action to unseat the cartridge valve and a separate needle valve controls gas flow (Figs. 1 and 2, not shown).

Title: Controlling arcing conditions in electro-discharge machining apparatus
IPC: B23H7/18
Filed: 1971-11-17
Abstract: 1323968 Electro-erosion CINCINNATI MILACRON Inc 17 Nov 1971 [21 Dec 1970] 53433/71 Heading B3V [Also in Division G3] The occurrence of arcing during electrodischarge machining is sensed by detecting the absence of signal noise during a discharge pulse and thereupon alternately decreasing and increasing the machining gap size to restore normal conditions. In the system shown, a D.C. supply 32 is switched by a circuit 30 to provide pulses to a machining tool 12 and workpiece 14 spaced by a gap 16, the magnitude of which is controlled by a servomechanism (not shown). Under normal conditions, each voltage pulse is immediately followed by a noise signal, but this signal disappears if arcing takes place, and a detector circuit 18 then supplies a signal to a cycle controller 36. A first controller output signal drives a stepping motor 42 to reduce the gap incrementally until a short circuit is detected by a circuit 24. At the same time, a second controller signal reduces the pulse energy to a minimum by adjusting switches 46, 48. The short circuit detector 24 now terminates the first output signal, and the controller 36 stores the distance moved by the tool 12. A switch 50 cuts off the pulses to the gap, and a motion generator 38 is energized to cause the motor 42 to move the tool away from and towards the workpiece a number of times to dislodge from their surfaces any deposits which might be causing arcing. Next, the controller 36 drives the motor 42 to separate the tool and workpieee by the same distance as before arcing was detected. The noise detector 18, Fig. 6a (not shown), includes pulse voltage and current sensors and multivibrators which define a sampling window. The part of the pulse lying in the window is applied to a megacycle pass filter which gives a zero output in the absence of noise. The reception of several successive zeroes may be necessary to trigger the cycle controller.
