[Also in Group XL (c)] A resonant transfer switching circuit for a time division multiplex system comprises a number of subscribers' stations e.g. A1, An connected to a common transmission medium via low-pass filters LP, inductors L1, Ln and switches K1, Kn. The last element of each filter comprises a shunt capacitance C1, Cn which forms a resonant circuit with the inductance. The total stray capacitance Cj is increased such that Cj = <SP>2</SP>/ 3 C or <SP>2</SP>/ 15 C where C = C1 = Cn. The charge on Cj is then mainly zero at the end of a transmission pulse, any small remaining charges being removed by periodically operating the contact Kk. The input circuit to the switch Kn includes a series capacitance C, which may be shunted by a resistor Rp, the value of the capacitance C and the primary inductance of the transformer Tr being chosen such that the control current of the switch has a zero value at or about the rear edge of the control pulse (see Group XL (c)). The control circuits of a number of switches 11 . . . 23 may be connected to form a matrix, Fig. 11. In order to operate, say, switch 12, contacts gv2, gh2 are closed and the subsequent closure of contact Km allow current to flow through the control circuit of switch 12.

Title: Improvements in or relating to Inking Mechanism of Printing Presses.
IPC: B41F31/08
Filed: 1917-12-27
Abstract: 115,001. Goss Printing Press Co., (Goss Printing Press Co.). Dec. 27, 1917. Inking-apparatus.-Relates to means for driving an ink-supply roller of a printing-press from a source independent of the press, and means controlled by the speed of the press for varying the speed, so that the roller is driven at lower speed relatively to that of the press as the speed of the press is increased; a spraying-device for supplying the roller with ink is described. As shown, the ink drum 11 is inked by a messenger roller 13 from a supply roller 12 on to which the ink is sprayed from a reservoir 18 through nozzles 14, pipe 15, and valve 19 by means of a force pump 16 in the reservoir driven by a shaft 17. The roller 12 is driven by bevel gear 27, 29, shaft 3) and worm gear 31, 32 from an electric motor 34. This motor is controlled by a rheostat 35 which is set to drive the motor at a comparatively high speed when the press is at rest. The arm 36 of the rheostat is operated by a governor 37 on a shaft 38 geared to the press, and when the press is driven, and as its speed increases, the arm 36 is moved to increase also the speed of the motor 34 and the roller 12, but to a less extent than the increase of the speed of the press. The speed of the roller 12 therefore is less relatively to the speed of the press when the press is running at high speed. The ink on the roller 12 is regulated by a blade 21 adjustable by a number of screws 22, and surplus ink removed by the blade falls into a trough 23 and passes back to the reservoir 18 through a pipe 24 and strainer 25. A scraper blade 26 removes lint &c. from the roller 12.

Filed: 1939-07-03
Abstract: 534,460. Preserving food. BENSEL, D. July 3, 1939, No. 19374. Convention date, April 26, 1939. Drawings to Specification. [Class 49] A process of preserving food comprises placing the cleaned food product in a flexible container of impervious material capable of being sealed by heatsealing this container and placing it in a rigid closely, confining cooking container which prevents the flexible container from being ruptured by the internal pressure generated during the cooking, and then subjecting the rigid container to heat to cook the food. The cooking container is subsequently cooled and the flexible container removed therefrom. The flexible container may be made of chlorinated rubber, such as the material known under the Registered Trade Mark " Pliofilm," or of transparent or opaque heat-sealing paper products. The charged and sealed containers are placed in side-by-side compartments in a vessel having a pressure-tight lid retained in position by pivoted screw-clips, and after cooking and cooling are removed from the compartments and placed in carriers constructed of rigid board or chip board. Alternatively, the containers are superposed in a deep confining vessel, adjacent containers being separated by sheets of paper. The separator sheets may be dispensed with by making the flexible container of laminated sheet, the inner ply being of " Pliofilm " and the outer ply of paper or other suitable non-sticking material. Inspection windows may be formed in the outer ply, the transparent inner ply permitting inspection. Food products requiring cooking in a partial vacuum, commercially known as dry pack, are placed in the flexible container and the required vacuum drawn,.following which the containers are hermetically sealed and subjected to cooking and cooling as before. The flexible containers are now placed in the carrier containers, or they may be first placed in the latter and cooked until done and thoroughly sterilized. When the food is to be used, the flexible containers are heated in boiling water, opened and the food is served.
