Abstract: 1,258,415. Valves. MAC VALVES Inc. 24 Dec., 1968 [14 Oct., 1968], No. 61429/68. Heading F2V. In a solenoid-operated reversing valve having an inlet port 14, a service port 21 and an exhaust port 26, Fig. 2 (not shown), control of flow between the respective ports is achieved by appropriately changing the state of a solenoid 13, the solenoid, when energized, causing downward movement of an armature 50 and hence corresponding movement of a valve member 38, such downward movement being effected in opposition to a return spring 34. Interposed between the valve body 10 and the solenoid and armature, there is a floating polepiece 53 which, in the de-energized state of the solenoid, is urged by a spring 59 on to an abutment 58. Subsequent to the solenoid being energized and valve member 38 engaging the lowermost seating 22, the polepiece overcomes the force of spring 59, moves upwardly and, by virtue of the provision thereon of a shading coil 57, locks on to the armature and so serves to reduce the inrush current to a locking current. The armature stem 37 is made to contact the valve member stem 11 at all times by the provision of a spring 83 between the topmost part of the armature and the valve casing cover 44. The valve member is made from two resilient portions 35 separated by a metallic flange 67.

An exchange system has link circuits C, called conversation bridges, in which there are stores for the identities of a calling and a called subscriber, the stores being accessed for writing and read out over associated gates P that are blocked against writing if the link is busy, a scanning counter CIA driven from clock-pulse source 1 examining subscribers' lines one by one and halting on off-hook conditions, such halting operating a switch 2 to divert the clock pulses to a link scanning counter CCP which reads out all the identities of subscribers in the link stores one by one to be matched at 5 against the identity of the off-hook subscriber set up on counter CIA, the absence of a match indicating a call origination and operating a bi-stable 6 to prime the link gates P and start up counter CCP in its second function of finding a free link C, the gate P of the first free link being uninhibited and allowing the calling line identity from CIA to be written in the calling subscriber's store of the link, a match being established in circuit 5 in order to throw the switch 2 and continue the scanning count in CIA. The first pulse to advance C1A resets the link scan counter CCP and the bi-stable 6. If the off-hook condition found by counter CIA relates to a line already associated with a link C, the first scanning function of CCP finds the corresponding identity in a link store and a match produced in circuit 5 throws switch 2 to restore scanning by CIA. If the off-hook condition is a call origination but the second scanning function of CCP finds no free link C, the position of counter CCP and the set state of bi-stable 6 opens an AND gate to throw switch 2 and continue the advance of CIA. The scanner counter CIA functions in the manner described in co-pending Application No. 14135/69.

Abstract: 1321974 Educational appliances MATSUSHITA ELECTRICAL INDUSTRIAL CO Ltd 3 Feb 1971 3854/71 Heading G5G [Also in Division G2] An apparatus suitable for projecting an ordinary film and an educational film having portions of its images relating to questions and answers includes a light source, screen, film loading device and means for preventing part of the image from being projected. As shown in Fig. 12 there is a screen 103 on one face of housing 102 which includes the light source and film loading device (not shown). The right hand side of the screen 103 may be blanked off by frame 117, when rotated through ninety degrees from the position shown. Apertures 125a, 125b, (125c) in the frame 117 are filled by plates 126a, 126b, (126c). Knobs 131a, 131b, 131c when rotated with the frame 117 parallel to the screen 103 rotate their respective plates back to the position shown. Thus in the projection of an educational film, a question posed by an image on the screen requires the viewer to select one of three (or more if extra plates are present) answers by rotating the appropriate knob. This permits an image to be projected on to the now no-longer blanked off portion of the screen 117 so that the viewer can be informed whether his selected answer was correct. When an ordinary film not requiring an input from the viewer is projected, the frame 117 and hence the plates 125a, 125b, (125c) are placed as shown so that the whole screen can be used. The frame may be held by a magnetic plate 167 or clip (267), Fig. 15 (not shown). Alternative embodiments use various means to move the plates. As shown in Fig. 3 knob 31a having band 30 can wind up a blind 26a covering aperture 25a by co-operating with extension 28 of rod 27a when the frame 17 is in position for the projection of an educational film. In this embodiment the frame 17 is held in its two positions by spring plate 24 engaging one of the notches 23a, 23b in the wheel 22. In Figs. 16, 17, 18 (not shown) the knobs 131a, 131b, 131c are replaced by knurled discs (330a), (330b), (330c) on the shaft about which the frame and plates pivot. Part of the periphery of these knobs projects through the casing of the apparatus and the viewer responds by rotating the selected disc and thereby its plate. In Figs. 19, 20, 21, (not shown) the plates are simply sheets slid in behind the screen. The films shown may be accompanied by a commentary provided by a magnetic tape recording and this tape may include control instructions to automatically advance the film when the apparatus is not being used with the screen partially obscured.
