Abstract: 333,299. Standard Telephones &. Cables, Ltd., (Deakin, G., and Polinkowsky, L.). May 14, 1929. Automatic exchange systems.-In a two wire junction including a transmission bridge, a relay is provided to cut out the bridge immediately the junction is seized, thus providing a metallic loop for impulsing, a. polarized relay reinserting the bridge when impulsing has finished. When the junction is seized under control of a register-controller, Sbr pulls up energizing Ar which cuts through a metallic circuit including polarized relay Cr. Br energizes and feeds forward holding earth for the switch train. When the register controller releases, current flow is reversed over the a wire and Cr pulls up releasing Ar which re-inserts the transmission bridge. When the called party replies Scr energizes replacing Sbr by low-resistance, relay Sar enabling a supervisory condition to be returned. When the calling party clears Sar releases and Br falls away releasing the following switch train. The invention is illustrated as forming part of the system described in Specification 333,300, in which reverting-impulse control is employed.

Title: Sheet separating device
IPC: G03B27/24
Filed: 1947-06-11
Abstract: 626,017. Sheet delivery-apparatus. BRUNING CO., Inc., C. June 11, 1947, No. 15410. Convention date, July 23, 1946. [Class 100 (i)] [Also in Group XX] A method of separating a pair of sheets in face-to-face relation is described for the separation of sheets of sensitized material 25 from tracing sheets 23 after passing through a printing-apparatus comprising a " Pyrex " (Registered Trade Mark) or other light-transmitting cylinder 17 in which is arranged a mercury vapour lamp 19. The cylinder 17 is arranged in a casing fitted with an exhaust pump 40 which causes ventilating air to enter passages 42, 44, 46, and the cylinder 17 is formed with a duct 20 which acts as a ventilator, and/or light shield or reflector. The sheets 23, 25 are fed to the cylinder 17 by means of tapes 21 and rollers 26, 27 keep the sheets in place on the tapes until engaged by the cylinder, and after printing the sheet 23 is detached from the sheet 25 which is led to a developing apparatus, the sheet 23 being separated by a separator 36 and delivered to a tray 37 fitted with a scraper 38. Fig. 2 shows one form of separator in which a pressure chamber 51 is connected by a pipe 49 to a blower 47 driven by the same motor 50 which drives the pump 40. The sheets 25, 23 pass over a coverplate 56 fitted to the chamber 51 at a spaced distance, and orifices 54 direct air at a high velocity between the cover-plate 56 and sheet 23, thus inducing a subatmospheric pressure which attracts the sheet 23 towards the plate 56, while at the same time the sheet 25 is attracted to the bands 21 by the subatmospheric pressure due to the ventilating action at the passage 44. The stripping of the sheets from the cylinder 17 is assisted by air blasts directed by the plate 56 from apertures 61 in the chamber 51. In a modification, Fig. 3, the separation is effected by means of a pair of slightly staggered pressure cylinders 71, 72 formed with restricted openings 74, 77 which act on both sheets similarly to the action of the separator, Fig. 2, thus causing the sheets 23, 25 to take different paths as shown. The chamber 51, Fig. 2, can be moved away from the cylinder 17 for cleansing purposes.

Abstract: 658,716. Pit props. SCHUBERT, A. June 10, 1949, No. 15468. Convention date, June 11, 1948. [Class 20(ii)] A plurality of rolling pieces o, in the form of laminal or elongated section, is arranged between two parallel gripping, jaws m, n between flanges m<SP>1</SP>, n<SP>3</SP> on which they can roll, and which, under the action of wedges f, g, frictionally connect upper and lower members a, b of a pit prop. The wedges f, g are arranged in a box or casing carried by the member b f being slidable and g fixed, and gripping pressure is applied to the upper member a by driving a wedge member h transversely of the casing. Downward movement of the member a due to subsidence causes the pieces o to roll into a position of greater radial length and give rise to a supplementary frictional resistance of movement of member a relatively to member b. The position of the inner jaw m may be regulated by a screw p to limit the rolling path and control the weighting. The member n is normally held raised by a spring q. The prop head may be connected to the upper prop member a by a ball retained in position by a ring welded to the member a. A friction packing may be placed between the gripping jaw and the upper prop member. In a modified form the inner gripping member a may be dispensed with the rolling pieces then bearing directly against the upper member of the prop around its circumference.
