Title: Improvements in or relating to the projection of stereoscopic cinematograph images
IPC: G03B35/00
Filed: 1943-10-16
Abstract: 570,878. stereoscopic kinematography. WRIGHT, E. H. Oct. 16, 1943, No. 15220. Addition to 555,670. [Class 97 (i)] A system for projecting right and left eye stereoscopic images arranged alternately on a film comprises stationary means situated in the light beam for producing plane-polarized light and means for converting the plane-polarized light during picture shifts alternately into clockwise and anti-clockwise circularly polarized light, so that the right and left eye images are projected respectively by light of clockwise and anti-clockwise polarization, or vice versa. As shown, the light beam passing the condenser 2 is plane-polarized by passage through a plurality of Nicol prisms 4 with their polarizing axes parallel. It then passes through the film 5 and a band 7 of half-wave retardation material which is formed with sprocket holes and moved with the film, and is such that it rotates the plane of polarization through a right angle during the projection of alternate frames. Thus, it may consist of a flexible carrier with windows of mica or other half-wave retardation material with their axes alternately at 45 degrees,. and parallel, to the plane of polarization. Alternatively, it may consist of a continuous strip of half-wave retardation material with the portions corresponding to alternate film frames cut away or rendered inactive. The light beam then passes through the objective 8 and a quarter-wave retardation plate 31 which causes the beam to be circularly polarized in opposite directions during the projection of successive frames. An angularly adjustable half-wave retardation plate 11 may be provided to phase the polarized light correctly with the viewing analyzers. Quarter-wave retardation devices may be substituted in the endless band 7 for the active and inactive half-wave portions, the stationary quarter-wave plate 11 being dispensed with. Other systems are described using rotating or oscillating half- or quarterwave plates in place of the flexible band 7. Specifications 486,111 and 519,488 are referred to.

Title: Improvements in or relating to u-shaped pipe bends
IPC: B21C37/28
Filed: 1933-06-01
Abstract: 420,172. Closing pipe ends by dies. WHITTLE, R. W., Elworth Works, Sandbach, Cheshire. June 1, 1933, No. 15791. [Class 83 (iv)] In forming a U-shaped pipe bend, dies d contract the end of a single tube, formed at the end of two tubes, to produce a tubular extension which ultimately becomes closed and parallel-sided providing a substantial length h for welding together the material. A die l, having a small recess n corresponding in location to the extension, forces inwards and compacts the extension to form an homogeneous mass, the thickness of which decreases as the distance from the end increases. The initial contraction is effected by a series of reciprocating and rotating dies having in successive dies conical openings, of progressively varying angularity, leading to parallel sided circular openings which gradually diminish in size in successive dies. Specification 420,106 is referred to.

Patent GB-158592-A (GB)
Abstract: 158,592. Western Electric Co., Ltd., and Deakin, G. July 28, 1920. Automatic exchange systems. - The hunting movement of a group selector, or of a line selector when making connection with an idle line of a series allotted to a private branch exchange, is prevented if all the lines of the wanted group are busy, or is brought to a stop if the last idle line becomes busy after the hunt has begun, and is resumed when one of the lines becomes idle. The Figure shows a modification of the circuits of the line selector shown in Fig. 3 of Specification 132,546, for connecting to an idle line of a group leading to a private branch exchange. The cut-off relay 365 of each P.B.X. line 361 - - 364 has a relay 366, 367, 368 or an equivalent resistance 369 in parallel with it, these parallel circuits being interdependent, so that any one of them is closed only when all the following lines are busy. When the selector is set on the first P.B.X. line 361, the sequence switch 300 moves to its 6th position. If the line 361 is idle, the relay 396 is energized, opencircuiting the power-magnet 377 and closing a circuit through the highresistance winding of relay 379, which locks itself through its lowresistance winding in series with relay 380, which drives the switch 300 out of its 6th (hunting) position. If all the P.B.X. lines are busy, so that the relay 365 of the first line is bridged by the resistance 369, the relay 396 is energized, in spite of the busy condition of the line, and prevents the selector from hunting, but the relay 379 is unable to energize and the switch 300 remains in its 6th position, and hunting commences as soon as a line becomes idle. If the first line 361 is busy but a subsequent line is idle, the relay 396 is unab. e to energize, and hunting takes place until the idle line is found, but if the last idle line becomes busy while the hunt is in progress, the relay 396 is energized over a relay such as 366 and stops the hunt until a subsequent line becomes idle.
