Title: Improvements in or relating to devices for storing and relaying data received in theform of electric signal impulses
Inventor: BAGGOTT ALBERT JEFFRIES
IPC: H03K21/02
Filed: 1959-08-26
Abstract: 886,977. Counting-apparatus. LANDIS & GYR Ltd. Aug. 22, 1960 [Aug. 26, 1959], No. 29189/59. Addition to 822,331. Class 106 (1). The arrangement described and claimed in the parent Specification, in which impulses from a plurality of transmitters are temporarily stored, the stores being sensed by an electronic switch so that an output pulse is sent to a totalizing counter from each store which has received a pulse, is modified in that the electronic switch, instead of comprising a multicathode counting tube, comprises a plurality of normally non-conducting electronic switching elements such as thyratrons. The Figure shows a typical pulse store B and the electronic switching device for scanning the various stores B, comprising a counting chain consisting of thyratrons V50/1, V50/2, &c. A mains transformer 54 supplies an operating potential to a pulse generator comprising a thyratron V51  and associated RC circuits R53, C52 and R55, C53. Initially, all the tubes V50/1 &c. are cut  off, the first pulse from the generator V51 fires, after a delay produced by an RC circuit, the first tube V50/1 over an auxiliary electrode connected between resistors R62, R63. The conduction in the tube V50/1 raises the grid potential in the tube V50/2 which fires on receipt of the next impulse from the generator V51, and since the tubes V50/1 &c. are connected to a common anode resistance R52, the tube V50/1 is extinguished. The tubes V50/1 &c. are connected in a ring and fire successively in this manner. Each time a tube such as V50/1 fires, a scanning impulse is sent over the corresponding line 56 to the associated storage device which, if storing a pulse, as described in the parent Specification, causes a voltage drop across an associated circuit R12, C8 to cause a transistor 51 to operate the energizing coil of a counter (not shown). Each store B is connected to an associated counter (not shown) via a terminal on a block TB1. Specification 827,041 also is referred to.

Abstract: 309,476. Balz-Erzr÷stung Ges. April 11, 1928, [Convention date]. Addtion to 303,055. Roasting furnaces.-In the roasting of zinc blende and like ores in superposed hearth furnaces as described in the parent Specification, sulphurous gases are withdrawn by a fan from one part of the furnace and returned to another, either alone or mixed with fresh air, for renewed participation in the process. In the furnace shown in Fig. 1 the hearths are hollow, and the spaces 5 therein are in communication on the one hand through valve-controlled pipes 6 with sources of supply for hot or cold air, and on the other with a collector 10, which leads through the fan 12 and connection 11 to the hollow rabble shaft 3, and which can be put into communication with the atmosphere through a valve 17. The three lowermost chambers communicate with the corresponding spaces 5 through apertures 8, and the respective connections 9 to the collector 10 are controlled bv valves 13. In operation cold air is supplied to the spaces 5 of the uppermost chambers, and sulphurous gases are withdrawn from the three lowermost chambers by the fan 12, the mixture being passed to the second and third chambers through the apertures 4, and to the lowermost chamber through the perforations 15. Hot air may be delivered to the spaces 5 of the lower chambers for supplying additional heat. In a modification, Fig. 2, in which the hearths are alternately fixed and rotary, and in which the lowermost hearth is heated by a fire-place 29, and certain of the fixed hearths are cooled by air chambers 5, sulphurous gases are withdrawn through the connection 23, and are returned through either or both of the connections 25, 11<1>. Air may be supplied to the circulation system either through the pipe 6' or from the spaces 5. In a further modification, Fig. 3, the uppermost chamber 31 acts solely as a dust-collecting chamber, and the space 5 in its floor is in communication with the atmosphere through the valve 7 and with a collector 10 through the valve 13. The space 5 of the second floor is in communication with the atmosphere through the valve 7<1> and with the chamber beneath it through apertures 8, and the air and gases passing into the space are supplied by the fan 12' through the perforated nozzle 24 to the discharge space 14 of the furnace. The spaces in the remaining hearths are each connected at two points to the collector 10, the connections above the valve 32 being controlled by valves 13<1>. By this arrangement air can be passed through the uppermost hearth only, or if the valve 32 is closed and the valves 13<1> opened, the air from the uppermost hearth can be passed through the spaces 5 of the two lowermost hearths on its way to pipe 11 and rabble shaft 3. The Specification as open to inspection under Sect. 91 (3) (a) describes a furnace similar to that shown in Fig. 2, but in which none of the hearths is cooled. This subject-matter does not appear in the Specification as accepted.

Abstract: 704,675. Feeding sheets. AYERS, F. L., and GRIMSHAW, J. P. Oct. 17, 1951 [Dec. 11, 1950], No. 30227/50. Class 100 (1) Faulty-feed detecting devices.- A device for detecting the absence of a sheet in the feed of sheets, e.g. to a wrapping machine, comprises a switch actuating mechanism having a displaceable switch actuating member, e.g. a push button 4 located in a recess 5 in the feed table 2 and operated by a plunger 1 which, when there is a sheet of material 3 in position bears on the material and urges it against the switch actuating member 4 to move it and effect operation of the machine and which is arranged to avoid contact with the switch actuating member in the absence of a sheet of material. The plunger 1 is formed with a tubular end which, in the absence of a sheet 3, will telescope over the end of button 4. The button is preferably arranged below a corner of the sheet 3. The plunger is lifted to allow a sheet to pass thereunder by a sliding bar 7 having a wedge shaped cam surface 9 passing through openings 1b in the plunger 6a in the guide block 6. The bar is displaced, to lift the plunger or allow it to fall under gravity to actuate the switch, by a cam 10 acting through a follower rod 11 and links 8. When it is desired to put the actuation of the machine under the control of the operator, the bar 7 may be supported on a spring-carried platform 14 so that the switch is not actuated until the operator has applied finger pressure to the upper end of the plunger to compress the springs 15. An eccentric 17, bearing on the upper side of the bar 7 is rotatable to press the bar downwardly so that the springs 15 are compressed and the actuation of the switch becomes automatic. The plunger is lifted to free the sheet as soon as the switch is actuated to effect operation of the machine by a gravity loaded lever 21 which is freed (by movement of a part of the machine) to bear downwardly on the bar 7 through a pushrod 20 so that the bar pivots about the platform 14 and lifts the plunger slightly. Specification 692,796 is referred to.
