Title: Gas discharge detection apparatus
IPC: G01N27/70
Filed: 1962-12-11
Abstract: 987,279. Leak detecting apparatus. VARIAN ASSOCIATES. Dec. 11, 1962 [Dec. 15, 1961], No. 46794/62. Heading G1N. A leak detector for a gas discharge device 13 operating at very low pressure within a vacuum tight envelope 14 to be monitored comprises a power supply 12 for the discharge device 13 means 75 (Fig.2) for providing a voltage proportional to the total current drawn by the device 13, means 154 to provide a variable voltage in opposition to the first voltage and means 16 for measuring the difference between the two voltages. In the embodiment shown in Fig. 1 the power supply 12 includes a constant voltage transformer 20 which is bypassed unless the current drawn by the discharge device 13 which is a sputter ion pump is below a certain value when relay 13 opens removing the current from relay 36 and connecting the primary winding of the transformer 34 to the secondary winding of the constant voltage transformer. The current passing through the sputter pump 13 produces a voltage across resistors 75 which is compared with the voltage produced on potentiometers 120, 123 by a long tailed pair 95, 96 giving an indication on meter 135. If an external record is required switch 103 alters the differential amplifier circuit and provides a signal at 145 which has one side earthed for use with external equipment. To operate the device switch 25 is depressed switching in relay 21 which is self holding, and switch 42 is closed short circuiting relay 58. As the sputter pump 13 reduces the pressure the current falls to a steady value which is so low that the constant voltage transformer 20 is switched into the power supply circuit. Switch 42 is now opened so that too large a current through resistor 55 switches relay 58 thus removing the power. Switch 74 is then adjusted to give an indication on meter 67 and then the D.C. voltage source provided by potentiometers 120 and 123 is adjusted in conjunction with sensitivity switch 129 to give a half scale reading on the sensitive meter 135. To test for leaks a gas is now sprayed on the discharge apparatus and any resultant change in equilibrium current is detected on meter 135. If two gases are used, say oxygen and argon, then deflections will occur in opposite directions further improving the sensitivity. It is stated that the detector is useful for the control of the manufacture of discharge devices. The connection of the point 51 to the core of transformer 34 is stated to reduce the effect of transformer leakage currents.

Title: Improvements in and relating to photographic printing apparatus
IPC: G03B27/80
Filed: 1969-09-29
Abstract: 1,222,906. Photographic printing control. AGFA-GEVAERT A. G. Sept. 29, 1969 [Sept. 27, 1968], No.47796/69. Heading G2A. In a photographic printing apparatus, part of the printing light from source 13 falls on a photo-multiplier 4 forming part of a timing circuit which terminates the exposure after a predetermined quantity of light has been received by the photo-multiplier. A constant intensity light source 18 is also provided for standardization or calibration purposes whose light falls on photo-multiplier 4 only when it is not illuminated by source 13. As shown, light from source 13 passes through the original 14, and is focused by a lens 15 on to the copy sheet (not shown). This light beam may be interrupted by a shutter 16 controlled by an electromagnet 17. Part of the light is deflected by mirrors 11, 12 to the photo-cathode of the multiplier 4, which is part of a timing circuit including a capacitor 21 and a switching triode 23. Light from the constant intensity source 18 can also be interrupted by a shutter 19 controlled by an electromagnet 20. When the printing step is initiated, a relay 22 operates, which opens shutter 16 and closes shutter 19. After the charge on capacitor 21 has reached a predetermined value, the triode 23 becomes conductive, and actuates a relay 24 which releases relay 22. The triode is thus rendered non-conductive, and shutter 17 closes, so terminating the exposure. The multiplier 4 is connected to the secondary of a transformer 3, whose primary is connected to a voltage supply through a number of variable resistors 5, 6, 7, 8. These can be adjusted to take into account various properties of the original or copy sheet. To standardize the apparatus, a change-over switch 9a switches into circuit a variable resistor 10 in place of resistors 5, 6, 7, shutter 16 is maintained closed, and shutter 19 is opened, so that the photo-cathode receives light only from source 18. The exposure time is measured by a clock 25, and resistor 10 can be adjusted so that this is a round figure, e.g. 1.00 sec.

The open end of the closed bladder is secured by a split ring to a spray ring 57 by means of which a curing medium, cooling water or vacuum may be introduced into the bladder; this ring is secured to a cylinder 65 supported on a vertically adjustable post 66. With the press closed and the ring 57 in its lowermost position the bladder rim is clamped between the ring and a bottom toe ring 56. The closed end of the bladder incorporates a moulded-in socket portion 71 supported by and connected to a correspondingly shaped member 70 at the top of a post 68 attached to a piston 67 operated pneumatically within the cylinder. A tyre ejection mechanism includes a pilot hose 51 which fits within the socket portion and is attached to a rod 50 extending through a cylinder 45 and depending from a piston and cylinder assembly 49 on the cylinder. The ejector mechanism is driven vertically by an ejector cylinder 42 to eject the cured tyre from the upper mould section following which the assembly 49 moves the nose 51 relative the cylinder to move chuck plate segments 54 radially inwardly relative an upper toe ring 47 whereby the cured tyre falls on to a discharge conveyer 122. The pilot hose is grooved to operate pivoted bell cranks 53 connected to the chuck segments. In the modification of Fig. 2 a guide tube 92 carrying the socket member 70 slides within a sleeve 84 and is urged upwardly by a spring 94 to extend the bladder, the upward stroke of the tube 92 being controlled by an adjustable stop nut 91 on a post 89. With the press in the open position of Fig. 3 the loader 98, mounted on a bracket 99 depending from the upper part of the press locates a fresh carcass C on the lower mould section. The loader includes a carriage 102 vertically movable between guides 100 on the opposite sides of the press, and includes a drive cylinder 105 on a support 104 which actuates tyre gripping fingers 108. A bladder restraining plate 114 is urged downwardly by a spring 116, and a pilot nose 115 engages within the socket portion of the bladder. Before retracting the carriage the bladder is inflated to grip the carcass. In a modified chuck arrangement for engaging the upper beads of tyres in the press, a number of chuck sector plates 126, Fig. 6, are pivoted to a housing 131 by pins 133 and are connected to a pilot nose 127 by links 137 whereby rotation of the nose in opposite directions produces radially inward and outward swinging movements about their pivots. Rotation of the nose is effected by a pair of pneumatic cylinders whose drive rods are connected to an arm extending diametrically from a rod carrying the nose.
