Title: Improved method of printing photographic sound records
IPC: G03B27/46
Filed: 1935-03-21
Abstract: 449,633. Photographic printing of sound-record films. MIHALY, D. VON, 3, Hildegardstrasse, Wilmersdorf, and PINTSCH AKT. - GES., J., 71, Andreasstrasse, both in Berlin. March 21, 1935, No. 8851. Convention date, June 16, 1934. [Classes 98 (i) and 98 (ii)] The single sound track on a primary film 1 is copied on to a secondary endless band film 4 in the form of a continuous track extending a number of times round the band parallel to the edges thereof, the record shifting at intervals from one track to the next, by repeatedly passing the band in the same direction through the light beam from a source 8, which, after passing through the film 1, is reflected on to the band 4 by mirrors 9, 10 through a slotted mask 11, and by causing inter. mittent relative movements between the band and the light beam in a direction transversely of the band after each sub. stantially complete passage of the band through the light beam. The film 1 and band 4 are driven respectively by sprockets 6, 7 mounted in a common driving spindle 18. As shown, the mirror 10 and mask 11 are mounted on a movable support 19 carrying a ratchet bar 16 with which engages a pawl 15 forming the armature of an electromagnet 14 in the circuit of which is a contact 13 which glides on the edge of the band 4 and is adapted to engage at intervals in a notch 12 therein so as to close the circuit of the magnet 14 and cause the mirror 10 and mask 11 to be shifted in a direction transversely of the band. Alternatively, the control of the relative lateral movements may be obtained from the film 1 which is then provided with notches or perforations at intervals corresponding to the length of the band 4. In the case of contact printing, one of the two films is moved laterally at predetermined intervals. The original track may be transferred on to a narrow endless band at a reduced scale and the record on the endless band may be made up from the sound records of several different primary films or from selected records of a multi-track primary film.

Filed: 1929-03-20
Abstract: 308,722. Associated Electrical Industries, Ltd., (Assignees of Penney, G. W.). March 27, 1928, [Convention date]. Stuffing-boxes, substitutes for; draining; cooling; with packing device acting when apparatus is at rest; packing, metallic.-Packing, which is particularly applicable for preventing the escape of hydrogen from the casing 3 of a dynamoelectric machine, comprises in combination an oil or other liquid seal, a ring, which is adapted to seal the casing when the apparatus is at rest and to be lifted by the oil pressure when the shaft is running, together with oil throwers and an auxiliary packing. An undivided ring 6 may be employed, which may have grooves 6a, and is attached to the bearing 4 by a bellows 7 enclosing a space 8. When the apparatus is at rest, the ring 6 is pressed against a collar 5 on the shaft by springs 10. Oil admitted under pressure to the space 8 by a passage 9, when the apparatus is running, presses the ring 6 away from the collar 5 and forms a liquid seal. The ring 6 may be replaced by segmental rings 24, Figs. 2 and 4, compressed by garter springs 25, the rings fitting closely in grooves in the casing and preventing the escape of gas when the apparatus is at rest. During running oil supplied by a pipe 9 lifts the rings from the shaft by a wedging action, which may be increased by means of wedge-shaped recesses 32 at the ends of the segments. Leakage oil is drained by a pipe 34 through a trap 35, the remaining oil being removed by throwers 17 and drained through a pipe 36 and trap 15. Oil vapour is prevented from entering the casing by gas circulated by a fan 37 and admitted by a pipe 38 to a space in a labyrinth packing 18. The gas is returned to the casing by a pipe 43, after passing through a chamber 42 in which the oil is absorbed. In a modification the packing box is cooled by oil circulated through a passage surrounding the grooves of a pair of packing-rings 24. Part of the oil is admitted to the space between the packing-rings, for sealing purposes.

Abstract: 1,018,299. Moderator structures. SOC. DES FORGES ET ATELIERS DU CREUSOT. March 11, 1963 [March 12, 1962], No. 9513/63. Heading G6C. A nuclear reactor reflector is formed of an annular ring of graphite blocks which are urged inwards against the pressure vessel by springs mounted on the external thermal shield. The blocks are air-cooled, bonded together by graphite keys and are shaped so that adjacent blocks engage only at the radially outermost surfaces so as to reduce the distorting effect of Wigner growth. Heat insulating bands are mounted on the reflector outer cylindrical surface, at the upper and lower ends, to reduce cooling and hence Wigner growth, at these areas. The springs bear against vertical metal bars which extend the full height of the reflector and which lie in vertical grooves in the periphery of the graphite ring. A horizontal reflector, which closes the lower end of the annular ring, is formed of two separate layers of graphite bars.

Abstract: 900,925. Transfer devices for feeding bread slices to endless conveyers. DEVONSHEER MELBA CORPORATION. March 21, 1960 [Oct. 15, 1959], No. 9838/60. Classes 78 (1) and 78 (3). A transfer device (Fig. 1), feeds bread slices on to endless articulated-plate conveyer 26 which feeds the slices into an oven to be baked. The device comprises pick-up 7 carried by support 8 mounted on pivoted arms 13, 14. The arms are driven by motor 25 via sprocket 24, rod 20, crank 19, gear 17, and pinions 9 and 10, so that the pick-up 7 engages and lifts slices on table 6 and deposits them on a plate 26 of the conveyer, the arms then swinging back for the next cycle. Endless conveyer 26 (Fig. 1). Plates 26 of the conveyer are articulated at pins 29; the conveyer being driven by the engagement of pins 29 in the teeth of sprocket 34, and the sprocket 34 being driven from motor 25 via sprocket 36, chain 37, and sprocket 24. Each conveyer plate 26 carries a complimentary plate 30 for covering the bread slices, and each complimentary plate 30 is pivoted at 29 and influenced by cam 32 so as to open to receive the slices. Pick-up 7 (Fig. 6).-The pick-up 7 has a carrier plate 48 which carries pins 42 and which moves relative to frame 45. The pick-up is shown about to pick up slices 41 from table 6, the piercing of the slices by the pins being assisted by the engagement of bell-cranks 57 (on pick-up 7) with projections 60 (on table 6) to cause the bell-cranks to move inwards to engage and lock the plate 48 to frame 45. Conversely, when the pick-up is about to discharge slices upon conveyer plate 26 (not shown in Fig. 6), heads 52 (on carrier plate 48) engage plate 26 to move carrier plate 48 upwards relative to frame 45 to strip the slices from the pins 42 to drop them on to conveyer plate 26, the bell-cranks now being free. Heads 55 act as limit stops.
