Patent GB-466301-A (GB)
Abstract: 466,301. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and PUCKETTE, C. C. March 2, 1936, No. 6232. [Class 40 (iv)] An emergency impulse transmitter for sending fixed trains of impulses e.g. for calling a fire station in case of fire comprises a setting device consisting of a pulley and operating cord or rack and pinion or a rotary handle, coupled to an assembly comprising a governor-controlled toothed disc, an impulse sending disc and auxiliary members, which is uncoupled from the setting device when this has been moved to a fully operated position, the impulse trains being transmitted during the return of the assembly to normal whereupon the setting device is re-coupled to the assembly. As shown, the impulse transmitter is set by pulling a cord 5 rotating a pulley 6 which, by engagement of a pawl 10 thereon with a plunger 12, rotates an assembly comprising a toothed governorcontrolled disc 13, an impulse disc 21 and a control disc 25, in the clockwise direction. A projection 24 on disc 25 ultimately moves a masking cam 23 from the position shown in which impulse springs 22 are held closed to a position in which projection 29 engages stop 30 in which springs 22 are free to engage impulse disc 21 and off-normal springs 31 are operated. Disc 25 is thus held, and further rotation of disc 21 permitted by slotted connections 35 enables plunger 12 to engage a depression 36 in disc 25 whereby the driving engagement with pawl 10 is released and discs 13, 21, and 25 rotate back to normal under the control of spring 20 and governor 15. The pulley, when released, is returned to normal by spring 8. When disc 25 approaches normal, projection 24 restores the masking cam 23 and relative movement between discs 25, 21 thrusts down the plunger 12 for engagement by the pawl 10 which yields as it passes the plunger. The impulse contacts 22 may be in series or parallel with the dial contacts the off-normal springs 31 disconnecting the dial contacts in the latter case and remaining off-normal to loop the line until re-set manually, removing the receiver prior to sending the alarm call being unnecessary.

Abstract: 1502478 Aligning a mask with photosensitive material INTERNATIONAL BUSINESS MACHINES CORP 14 Nov 1975 [23 Dec 1974] 46970/75 Heading G2A A process for producing a desired angular relationship between two objects comprises (a) providing a pair of marks on the first object (e.g. a patterned mask) which are a known distance apart, (b) providing a mark on the second object (e.g. an XY table for a semi-conductor wafer), (c) moving the second object so as successively to align the mark on the second object with the marks on the first object, (d) verifying the accuracy of the alignments by determining the distance between the alignments and comparing with the known distance, (e) repeating steps (c) and (d), if necessary, until the alignments are sufficiently accurate, (f) determining the angular position of the first object with respect to the second object from the change in position of the second object between the alignments of verified accuracy, and (g) producing the desired angular relationship between the two objects, the angular position of the second object being maintained constant during step (c). As shown, a table 11 having an alignment reticle 43 in the form of a Greek cross is movable in X and Y directions by means of motors for coarse and fine movement in each orthogonal direction from a reference position determined by sensors 27 and 29 into successive alignment with cross marks 68 and 69 on a mask 45 which is mounted for rotation about a pivot 54, after determination of the angular relationship between table 11 and mask 45 (Mask may alternatively be rotated about its centre). The marks to be aligned are viewed on a TV monitor screen 81 and alignment is effected by manual movement of a joy-stick 83. (The alignment may alternatively be effected automatically). During each alignment, interferometers 39 and 41 having associated counters 118 measure the movement in the X and Y directions, the measurements being stored in a system controller 85. After relative alignment of table 11 and mask 45, step and repeat exposure of a photo-sensitive wafer 21 on table 11 is effected (with repeat alignment when more than one mask is employed). In these exposures, an image of a pair of Greek cross marks is formed at each exposure site (the marks being a known distance apart) and these marks are employed for aligning the mask relative to the mask images for the formation of second level images. This alignment is effected by repeating the original alignment using a mark (2a) Fig. 7A (not shown) of one of the pairs and then successively aligning the other mark (2b) of the same pair, and a mark of a spaced pair, with the second mark 69 on the mask.

Abstract: 1,167,894. Telescope mirror blanks. OWENS-ILLINOIS Inc. Oct.24, 1966 [Oct. 23, 1965], No.47551/66. Heading G2J. [Also in Division C1] A light-weight glass or glass-ceramic "telescope mirror" blank is formed by positioning or inserting at least one shaped core 13 Fig.5 in a molten vitreous mass 11 in a mould 12, a part of the core extending to an outer surface 19 of the vitreous mass and such part 17 having a smaller cross-sectional area than that of the remainder 18 of the core and the core having a melting point below the fibre-softening point of the vitreous mass, the vitreous mass then being cooled until self-supporting and the core or cores then being melted and removed to leave cavities in the glass blank which is heat-treated to give the glass-ceramic, when such a glass is used. For some low melting cores, immersion in the glass cools the glass until self-supporting and melts the cores; alternatively annealing of the glass or the heat-treatment to form the glass-ceramic may be used to melt the cores which are then poured out. The cores 13 may be secured to the base of the mould 12 and molten glass poured in, or as shown in Fig. 5, the cores 13 are secured by pins 15 to a platen 14 and the cores are pressed into the glass in the mould 12. Hollow cores may be used, in which case the securing means to mould on platen incorporates inlet and outlet tubes for a heated fluid to maintain the core at the required temperature. As shown in Fig.8, pairs of cores 45, 46 are inter-connected by a securing pin 47 and by an annular part 48 having a plurality of openings 49 communicating with openings 50 in a recessed part 51 of pin 47, the pin 47 extending through the platen 56 and having a central bore 52 which can be connected to a vacuum source. After insertion in the molten glass, the vacuum is applied to assist the flow of glass between the cores 45, 46.

[Also in Divisions G3 and H2] In a " no break" A.C. supply system as disclosed in the parent application comprising a battery and mains fed charging unit feeding a thyristor inverter, two inverters 5, 6 are utilized having their inputs in parallel and phase displaced outputs in series, the extent of the phase displacement being controlled by a differential amplifier 8 responsive to a combined output so as to maintain the output voltage constant. The inverters are normally fed directly from a stabilized rectifier unit 1, but on failure of the supply from a trickle charged battery 2 through a diode 4. The frequency is determined by a quartz crystal 900 (on Fig. 2B) followed by a series of frequency dividing stages 901 to give outputs at A and B of 50 c.p.s. displaced by 180 degrees which are amplified by transistors T1-T4 and passed through differentiating circuits 32, 35 and diodes 36, 37 to give a series of positive pulses to a monostable circuit T5-T7 which has a square wave output L of variable width dependent on the signal H from amplifier 8, which signal has a threshold value determined by a Zener diode 39. The signal L is passed through a transistor T8, a Schmitt trigger circuit T9, T10, differentiating circuits 57, 58 and 65, 67 and diodes 59, 66 to a flip-flop circuit 11, 12, the diode inputs being synchronized through resistors 30, 31 with the outputs of transistors T2, T4. The flip-flop output 0 and a high frequency input P from a multivibrator circuit (Fig. 2C) including transistors T17-T20 is fed to a AND circuit formed by diodes 68, 69 to give a resultant signal Q which is supplied to transformers 82, 83 after amplification by transistors T13-T16. These transformers fire one pair of thyristors, e.g. 119, 126 and similar circuits (Fig. 2C) supply other pairs. The thyristors pass the battery current to transformers 143, 144 whose series connected secondary windings give a stepped square wave output to a load 149 whose voltage after rectification is sensed by the differential amplifier 8 comprising transistors T21, T22, which compares the voltages across potentiometers 157 and 164, 165 the output being amplified by transistors T23, T24 and passed to transistor T5. A resistor 170 provides negative feedback and improves linearity. Commutating circuits are provided for the thyristors as shown. The arrangement may be multipled to give a polyphase output.
