Patent GB-531460-A (GB)
Abstract: 531,460. Rotary distributers. SCINTILLA, Ltd. July 24, 1939, No. 21443. Convention date, July 22, 1938. [Class 38 (v)] A spark-jump rotary distributer, particularly for use on aircraft, and in which it is ensured that the spark-plugs are supplied in correct order, comprises a rotor 25 having two distributing conductors 27, 28, the lower ends 29, 31 of which co-operate with electrodes 201 ... 209 in the form of teeth on a ring 18 to which the H.T. lead 16 is connected. The upper ends 30, 32 of the conductors 27, 28, co-operate respectively with electrodes 221 ... 229 and 231 ... 239, corresponding to eighteen spark plugs. As can be seen from Fig. 3, the teeth 201 &c. are in the same radial planes as the electrodes 221 &c. and the member 27 has its tips 29, 30 in the same radial plane, whereas the electrodes 231 &c. are spaced halfway between the radial planes of electrodes 221 &c. and the tips 31, 32 are spaced from one another half an electrodepitch. In Fig. 3, therefore the electrode 221 is fed with H.T. by way of electrode 201 and member 27 but, assuming anti-clockwise rotation of the rotor, the next electrode to be fed will be 236, by way of conductor 28 and electrode 206. After that, 222 will be fed by member 27 from electrode 202, and so on. The double gap in air formed when member 27 moves away from electrodes 201, 221, prevents the next impulse from again breaking down the ionized path between those electrodes instead of passing, as it should, to the electrodes 206, 236. Insulating ridges 35 ... 37 and 39 are also provided to increase the air-distance between parts under tension and parts that are " earthed." In a modification, Figs. 4, 5 (not shown), the rotor has horizontal flanges containing the distributing member, these flanges being interleaved by inwardly-projecting flanges on the distributercasing so as to increase air-distances.

Abstract: 1387200 Dolls M I GLASS [trading as MARVIN GLASS & ASSOCIATES] 8 Dec 1972 [30 Dec 1971] 56682/72 Heading A6S A doll which first shuts its eyes and then falls over as if asleep has a head 12. Fig. 7, and a torso divided into two chambers 38, 76 with passageways 64, 70a, 50, &c between them through which sand, &c can flow. The upper chamber 76 is flexible, and holes 70a, &c are arranged only on the side of the doll shown, so that sand 41 empties more quickly from that side of the doll than from the other: this sand falls upon an inclined portion 48 of the bottom chamber, so that the upper chamber collapses towards that side and the doll ultimately falls over on that side. In the upright position shown, a valve 52 allows only slow flow of sand 41 from the upper to the lower chamber 38. By turning the doll upside down, Fig. 5, the valve 52 moves to an open position, uncovering a relatively large hole 66 for rapid flow of sand 41 from the bottom chamber 38 back into the upper chamber 26. At the same time, sand 41 flows through holes in a valve plate 108 to an extensible portion 100 of the upper chamber 76. The extensible portion 100 fills and expands inside a hollow neck 88 so that two weights 134, connected by a chain 132 to eye and eyelid operating mechanism 124a, &c, are held in the position shown. When the doll is re-inverted from the Fig. 5 position to the Fig. 7 position, the extensible portion 100 empties through the holes in the valve plate 108 into the upper chamber 76, thus allowing two weights 134 to fall and taughten the chain 132, so as to actuate the eye mechanism and close the eyelids 20. The doll subsequently falls over as described above. The dolls head 12 can rotate on a flange 118 of the neck. The head and torso shown are held inside a garment (28), Figs. 1-4 (not shown), which includes stuffed arms and legs.

Abstract: 1,273,410. Holography. SIEMENS A. G. Nov.25, 1969 [Nov. 26, 1968], No.57561/69. Heading G2J. An arrangement for reproducing Lippmann- Bragg holograms wherein the hologram E is illuminated by a light source Q, and a given observer position B o  is provided, from which position the line of sight S o  is so chosen that the reconstituted image is seen in the zone of optimum sharpness S B , includes means to suppress or substantially reduce any unwanted reflection S r  of the light source to the observer position, which reflection would at least partially overlap the image. Preferably the reflection suppressing means is a prism P a  which contacts the hologramcarrier H t  through an immersion liquid. The wedge angle of the prism may be chosen so that the reconstituted optimum wave S o  exits from the prism unrefracted Fig. 7. Desirably a prism of similar geometric proportions contacts the hologram carrier during recording of the hologram. One alternative way of erradicating undesired reflection is to apply a non-reflective coating to the front surface of the hologram. In a further embodiment Fig. 7 the light source Q<SP>1</SP> produces linearly polarised light which is incident on the front face of the hologram at the Brewster angle Y. It is preferred to use a white light source Q a beam of which is split by a polarisation splitter. The reflected polarized component is further reflected to be parallel to the non-deflected component and has its plane of polarisation rotated through 90 degrees.
