Title: Improvements in or relating to electron beam switching tubes
IPC: H01J31/04
Filed: 1951-06-04
Abstract: 691,577. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES. Ltd. June 4, 1951 [June 7, 1950]. No. 13179/51. Class 39(i). A cathode-ray tube for a switching circuit comprising at least one. electron gun 11 and at least one pair of deflection plates 12, 19 which are adapted to direct an electron beam to either of two electrode systems each of which comprises a secondary emitting cathode 13, 20 respectively and a further electrode 14, 21, is characterized in that between the electrode system there is arranged a screening plate 17 having a fixed high positive potential constituting a common secondary electron collecting electrode and opposite this plate in each system there is a plate shaped deflection control electrode 15, 22, and also in each system there is a further plate shaped deflection electrode 16, 23 at zero or low potential approximately in the plane of the first deflection electrode and between it and the pairs of deflection plates. A screen grid 18 may be provided and may be connected to the plate 17. In operation the electrons are directed by the deflection plates 12, 19 into one or other of the two electrode systems. If the grids 14, 21 are connected to the plate 17 the output cathode 13 or 20 of the system in use is either at the potential of the applied voltage (70v) or at the potential of the plate 17 (200v) according to whether the potential on the control deflection electrode 15 or 22 is such that electrons from the gun do not or do reach the cathodes. Thus an alternating voltage applied to the appropriate deflecting plate 15 or 22 is transmitted to its respective cathode as a pulse voltage the sides of which may be made steep by providing the cathodes with slanting edges 24, 25. In another method of operation inputs may be applied to the grids 14, and when the beam is deflected to pass to one of the cathodes, the corresponding grid is effectively connected to the cathode so that signal voltages may pass from the input to the output. In Fig. 4 there are only two electrode systems but a further pair may be provided on the opposite side of the cathode, the same cathode serving for both pairs of systems.

Title: Improvements in and relating to hand-operated die moulding machines, embossing machines and the like
Inventor: ENTWISTLE JOHN
IPC: A21C11/00
Filed: 1955-05-07
Abstract: 839,741. Pie-moulding machines. ENTWISTLE & WALKER Ltd. Aug. 7, 1956 [May 7, 1955], No. 13254/55. Class 87(2). [Also in Groups XI, XVI and XXXVII] A compression moulding press e.g. a pie blocking machine, has an electrically heated die head to which interchangeable dies may be detachably clamped by complementary quick release devices on the head or machine frame and dies, each die having a plane heat exchange surface for abutment contact. with a corresponding surface in the said head and the current to the electrically heated die head being controlled automatically whereby such current may be supplied for predetermined periods of time at predetermined intervals. As shown, the die head 14 is mounted on the lower end of a plunger 13 which is reciprocated in a sleeve 12 by the action of a cam-slot 37, or a cam surface corresponding to the top edge of the slot, in a lever 33 upon a roller 32 carried by a pin 31 mounted in the bifurcated top end 30 of the plunger 13. The cam-slot 37 is so shaped that the plunger travels rapidly on the first part of its downward path and then more slowly, the downward thrust thereon being at its greatest in the final stages of the plunger's descent. The roller 32 is mounted eccentrically on the pin 31 so that angular movement of the pin, which is locked in a given position by means of a recessed quadrant 39 attached thereto and a pin 40 slidably mounted in the bifurcated portion 30, results in a variation in the limit of movement of the die. The handle 38 of the lever 33 is offset at 38a so as tobe nearer the operator's right hand. When the handle 38 is released after the press has been operated a counterweight 36 on the lever 33 restores the parts to their inoperative positions. The supply of current to the heating element 16 in the diehead is controlled by an automatic energy control regulator 23 (see Group XXXVII). The die head carries levers 25 pivoted to the portion 14 which engage an annular groove 28 at the upper edge of a removable die 29 for the purpose of securing it to the die head. In a modification, wherein the die remains stationary and the workpiece is moved, the annular groove in the die is engaged by spring-biassed lugs mounted on the machine frame. Specification 839,742 is referred to.
