Title: Method for effecting an automatic continuous operation of copying telegraphs
IPC: H04N1/10
Filed: 1922-02-07
Abstract: 175,617. Petersen, M. H. Feb. 17, 1921, [Convention date]. Copying-telegraphs.-Relates to copying telegraphs in which a number of pictures can be telegraphed successively and automatically without interruption, and comprises means in the receiving apparatus whereby only that one of several recording arms may be illuminated which is operative at any instant. The pictures to be transmitted are carried on metal plates a<1>, a<2>, a<3>, which are fed from right to left through gearing operated by the synchronous motor e. A spider i is rotated by the synchronous motor k and, in the transmitting apparatus, carries at the ends of its four arms contacts which wipe successively over the plates, only one of the contacts being operative at a time. The receiving apparatus is similar, but sensitized paper is therein carried on the plates a<1>, a<2>, a<3>, and the arms of the spider carry optical apparatus, shown in plan, for projecting light upon the paper. A fixed vertical pencil of light d<4> is reflected by one of the faces b<1> of a pyramidal reflector along the arm i<1> to a reflector m<1>, while the reflectors and spider rotate together through a quadrant. The pencil then falls on the next face b<4> of the pyramidal reflector and thence passes to the reflector m<4> and so on. In order to secure synchronism, the motors e, k at the transmitting and receiving stations are synchronous motors all driven from the same source of power. The projecting devices may be given a reciprocating instead of a rotating motion. Specifications 105,914 and 168,650 are referred to. According to the Specification as open to inspection under Sect. 91 (3) (a), the metal plates a<1>, a<2>, a<3> carrying the pictures to be transmitted may be replaced by a band of metal foil passing over rollers, while the spider i is replaced by a revolving belt carrying contacts, similar changes being made in the receiving apparatus. This subject-matter does not appear in the Specification as accepted.

Title: Oil gas process and apparatus
Inventor: RICHARDSON ELLO ELWIN
IPC: C10G9/00
Filed: 1956-02-06
Abstract: 829,878. Oil gas. GAS MACHINERY CO. Feb. 6, 1956, No. 3618/56. Class 55 (2). In making oil-gas by alternately heating checkerbrick and dispersing oil on it, the heat run is effected by the tangential introduction of fluid fuel and preheated combustion air, or the combustion products therefrom, into the top of the shell containing the checkerbrick, to produce a helical downward flow with consequent uniform heating of the checkerbrick, the make oil being supplied at the top of the checkerbrick for downward passage through the shell whilst being converted to oil gas. As shown, two shells 11, 12 are used, air being admitted at 17 to be preheated during the ascent in the shell 11 to the conduits 29, 30, which are arranged tangentially to both shells 11, 12. Additional air is admitted at 15 and fuel oil is sprayed into the shell 12 by a spray 36, or into the top of the shell 11 by a similar spray, not shown. The heated air, or combustion products, enter the shell 12 tangentially and spiral downwardly to the stack 23. After a short steam purge from pipe 37, the stack valve 28 is closed, and oil is sprayed into the tops of both shells 11, 12. The oil sprayed into the shell 11 is partially vaporized and converted to oil gas by the residual heat at the top of the shell, and steam may be introduced at 37 to prevent any substantial downflow of oil vapours in the shell, the steam passing with the oil vapours to the shell 12. The oil gases pass down the shell 12 to the stack 23 and through a pipe 31 and wash-box to storage or distribution. At the end of the make run, a short steam purge from 38 precedes the reverse heat run, the air entering through conduits 18, 16 and the fuel oil through the spray 36 or the spray at the top of the shell 11. The combustion products descend spirally in the shell 11 and pass out through the open stack-valve 28. U.S.A. Specification 2,746,852 is referred to.

Title: Improvements in or relating to pulse delay system
IPC: H03K5/13
Filed: 1946-02-06
Abstract: 614,550. Saw-tooth or pulse generating circuits. PHILCO RADIO & TELEVISION CORPORATION. Feb. 6, 1946, No. 3709. Convention date, April 29, 1944. [Class 40 (vi)] A pulse delay system comprises a multivibrator circuit regenerativety intercoupled to produce a single cycle of operation when triggered by a pulse. The load circuit of one valve includes a differentiating circuit from across which an output is taken, the interval between the triggering and output pulses being determined by a cross-coupling between the valves comprising two serially connected time delay circuits, one of which has an adjustable delay. Valve T1 of a cathode-coupled multivibrator is normally cut off and valve T2 isconducting. A positive pulse applied to input terminal 26 causes the grid of T2 to drop in potential to well below its cut-off value. When condensers 21 and 24 have discharged through their shunting resistances sufficiently for the grid of T2 to reach its cut-off value, the valve conducts. When the cut-off value of T2 is reached, normal regenerative action occurs, there is a rapid rise of current through the inductance 12 in the cathode circuit of T2 and a pulse is produced at output terminal 27. The interval between the triggering pulse and the output pulse is dependent upon the time delay of networks 19 and 20 and is adjusted by the setting of potentiometer 14. In a modification, Fig. 3 (not shown), the delay networks are comprised by two condensers in series between the anode of one valve of the multivibrator and the grid of the other valve so that a direct-current path is not provided but such a path is provided between this grid and the cathode of the valve either directly or through a suitable potential source. A variable resistance may be provided in shunt with one of the series condensers.

Filed: 1975-01-29
Abstract: 1503191 Weighing apparatus W & T AVERY Ltd 9 Jan 1976 [29 Jan 1975] 3852/75 Heading GIN In a weighing machine wherein a digital weight signal is produced in successive sampling periods, a print-out of the weight is automatically made when the weight signal is unchanged for two consecutive sampling periods. As shown, the digital weight signal obtained from an A-D converter 11 during a sampling period is fed to a comparator 12 together with the weight signal of the previous sampling period retained in a store 10. The unit 12 determines the difference between these two weight signals and feeds this value to detector circuits 14, 16. Simultaneously the store 10 is updated. Detector circuit 14 senses when at least two consecutive outputs from unit 12 are below a predetermined value e.g. zero. When this condition is satisfied the wieght signal is assumed to be correct and a signal is fed to circuitry 26 to produce a print-out of the weight, unit price and total price of the test body, the information being obtained from random access memory 24. Detector circuit 16 senses when the difference signal from unit 12 is less than a predetermined value and prevents a further print out until there is a significant change in weight.
