Class 97(1) A panoramic projection system uses a film in which the two halves of the scene have been recorded lengthwise on either. side of the longitudinal centre line. In the form shown in Fig. 15 the lens system 104 is disposed in front of the film 101 and light therefrom is reflected from a mirror 105 the beam being divided by a reflecting wedge 164 the two halves of the beam are reflected from mirrors 107, 108 and passed through objectives 109, 110 and wedges 111, 112 to form images on the two halves of a curved screen 102. A member 177, having longitudinal ribs, is rotated by a motor 167 in the parts of the light beam corresponding to those parts of the images which are to be overlapped on the screen. This produces a shading effect which renders the join inconspicuous. All the lens systems are axially adjustable for focusing and the wedges 111, 112 are rotatable for aligning the projected images on the screen. The various reflectors are also adjustable. In the form shown in Fig. 4 the light beams from the film images pass through faces 31 of prisms B and are first reflected from the faces 30 and then through further. right angles, by other faces, downwards through the lens systems comprising.components U, V and W and then through achromatic prisms B. The lens systems are axially adjustable and the prisms are rotatable. The special: film required may be printed from one on which the whole panoramic image is recorded transversely on wide film or longitudinally on a film of normal width having a double shift.

Title: Improvements relating to card feeding mechanisms
IPC: G06K13/08
Filed: 1928-08-20
Abstract: 321,953. Thomas, A., and Power, R. F. Aug. 20, 1928. Paper - carriages; cardclamping arrangements; linespacing mechanism.-In a card-feeding arrangement for printing or punching machines, particularly the selectivepunching machine described in Specification 321,952, [Class 31 (ii), Punching and perforating machines &c.] , the cards are held cantilever-fashion in a carriage by clips engaging a card edge which lies in the direction of movement of the card, the carriage being associated with a line-spacing escapement and with means for opening and closing the grippers at predetermined intervals. The carriage is associated also with tabulating- mechanism, and means is provided for feeding cards from a magazine to the carriage. The card carriage comprises a vertical plate 103, Fig. 1, with pivoted card clips 100, which carries a rack 52, and is urged to the left by a cord wound on a spring-drum. The rack is engaged by a pivoted check pawl 62 actuated by a T-lever 33 pivoted to the frame, and an actuating pawl 64 on a lever pivoted to the frame and connected by a link 66 to the actuating-plate 27 for the punch-striker. Depression of a key moves the rod R to swing the lever 33 and raise the check pawl and the pawl 64 is lowered by the plate 27. Release of the key restores the check pawl and the movement of the carriage forces up the pawl 64 to move the plate 27 which restores the member R and resets the keys. The tension of the carriage thus restores to original position the striker actuating mechanism and resets the keys. When the key is fully depressed the carriage is momentarily held by both pawls. The card clips are controlled by a bar 104 and a bell crank 106 which is engaged on the back movement of the carriage by a pin 108 to open the clips. In this position the bar 104 is held by a detent which is released when a register pin 110 is projected through a hole on the carriage when the latter is in starting posifion. Tabulating - mechanism; carriage - releasing arrangements.-A finger-plate 69 on depression, actuates the lever 33 to raise the pawl 62 to allow the carriage to skip the whole length of its travel. A skip key 70 on depression rocks a rack 73 carrying adjustable clips 76 into the path of a projection on the carriage. The rack 73 on rocking actuates a lever 79 to free the pawl 62 and allow the carriage to skip a predetermined distance. Sheet-feeding arrangements.-The cards are stacked in a spring-urged magazine capped by a glass plate 118, and the top card is fed between an abutment on the plate 103 and the card clips by a picker mounted on a shaft 121 with lever 127 rocked by a lever 124 from the carriage. The magazine is arranged so that when one side is swung down for replenishing the cards the springs are held compressed. An aligning shutter 137 is rocked by a pin on the carriage to ensure the top cards being in alignment. The cards are received in an adjustable framework.

Abstract: 317,757. Rheinische Kampfer Fabrik Ges. Aug. 21, 1928, [Convention date]. 1, 8-Cineol (eucalyptol) is obtained from mixtures thereof with 1, 4-cineol, such us those obtained by the action of water-eliminating agents on various terpene compounds such as terpin hydrate, terpineol, terpin, and terpinenol, by treating The mixture at temperatures below 0‹ C. with substances having a hydrating action, wherehy the 1, 4-cineol is reconverted into terpineol or terpin hydrate, separating any terpene hydrocarbons, and recovering the unchanged 1, 8- cineol by subjecting the solution, preferably rendered alkaline, to steam distillation. Sulphuricacid of 60 per cent or phosphoric acid of 80 per cent may be used as the substance having a hydrating action. In examples, a mixture of terpene hydrocarbons (chiefly limonene, terpinolene and alpha-, #- and gamma-terpinene) and 1, 4- and 1, 8- cineol, which has been obtained by the action of water-eliminating agents on terpin hydrate, terpineol and the like, is cooled to -15‹ C. and added gradually to 60 per cent, sulphuric acid cooled to -12‹ C. The terpene hydrocarbons are separated, and the solution is made alkaline and steam distilled to obtain an oil containing eucalyptol, from which terpineol may be removed by vacuum distillation. The terpin hydrate and terpineol obtained may be treated again with watereliminating agents, and the resulting mixture containing 1, 4- and 1, 8-cineol may be again subjected to the separation process.
