Title: Improvements relating to thermionic valves or electron discharge tubes
IPC: H01J19/44
Filed: 1927-04-26
Abstract: 283,941. Naamlooze Vennootschap philips' Gloeilampenfabrieken. Jan. 22, 1927, [Convention date]. Vacuum tubes.- In a thermionic valve or other discharge tube in which a high vacuum is obtained by means of a conductive getter such as magnesium, the surface lying between electrodes which are maintained at different potentials during operation is roughened so as to provide a long leakage path and effective insulation in spite of any deposit of conductive particles. Roughening mav be produced by mechanical means such as sand-blasting, or by chemical means. An aqueous suspension of calcium carbonate may be applied to the pinch and dried by heating to 120‹. The pinch is then sealed into the bulb which is heated to 350‹-500‹ C., and the carbon dioxide and water vapour evolved are evacuated by a pump. Calcium oxide in a pitted state remains on the pinch, and, in addition to providing insulation, also serves to absorb water vapour. As shown. the top 5 of the pinch, and a glass or quartz arm 7 carrying filament supports 6, are roughened.

Title: Improvements in or relating to meat slicing machines
IPC: B26D1/143
Filed: 1929-04-10
Abstract: 309,499. Sabbe & Steenbrugge. April 11, 1928, [Convention date]. Grant of Patent opposed. Cutting slices in succession.-In a disc-knife reciprocating table machine, the slice feed mechanism becomes operative only towards the end of the return stroke of the under carriage, thus avoiding the rubbing of the meat against the knife. As shown in Fig. 1, the adjustable stop 4 on the machine frame contacts with an arm of a lever 5, which is retained by a spring 12 and has an arcuate upper end 5<a> with teeth which engage a pinion 6 loose upon the feed screw and carrying an arm 7 on which a pawl 8 is pivoted. The pawl 8 engages a ratchet wheel fast upon the feed screw. The pinion 6 has a smaller radius than the arc 5a, so that it moves through a greater angle than the are. This magnifying gear produces relatively large feed movements for small movements of the under carriage, thus permitting the feed to be effected very near the end of the return stroke of the carriage. In a modification, Fig. 3, the adjustable stop 4 is in the form of an eccentric and it contacts with a lever 7 pivoted at its lower end to the under carriage. 'The lever is connected to a pawl lever 5 by a link 6 and is returned by a spring 12. This arrangement also magnifies the feed motion. Reference has been directed by the Comptroller to Specifications 14291/13, 278,783, 282,761, and 2821,825.

Title: Improvements relating to locking devices for doors and the like controllable from a distance
IPC: E05C17/50
Filed: 1923-04-26
Abstract: 220,023. Dempster, D. E. April 26, 1923. Electrically operated fastenings; multiple bolt fastenings; catches, automatic; sliding bolts.- The spring-closed door of a bank, office &c. is adapted to be held in the open position by a catch and locked when closed by bolts entering recesses in the hinged end of the door in such a way that if a button at a distance is pressed, as by the cashier of a bank, electromagnetic means cause (a) release of the catch allowing the doors to close, and (b) the shooting of the bolts to lock the door preventing egress of a suspected person. The bolts are retracted by hand, springs or electromagnetic means. In the form shown in the Figures racked bolts 7 enter recesses 9 in the door to secure it and are operated by pinions 11 on vertical shafts 12 contained in light casings 13, the shafts 12 having each a pinion 14 engaged by a rack 15 on an extension 16 pivoted to the core 17 of a solenoid 18. A switch is arranged under the cashiers desk allowing him to energize the solenoid to attract the core 17 and so move the rod 16, turning the shafts 12. The catches 6 engaging members 5 on the doors to hold them open are first released by cams 40 on the shafts 12, allowing the doors to be closed by their springs, when the pinions 11 shoot the bolts 8 to secure the doors. A littte lost motion between the release of the catches 6 and the shooting of the bolts gives time for the doors to close before the bolts shoot home. The racks 15 are arranged so as to actuate the shafts 12 in the correct direction to shoot the bolt 7 simultaneously when the device is applied to double doors.

Divided out of 1,255,801. Heading C1A. The production of agglomerates for sintering  is controlled by mixing ferromagnetic mineral materials, water, fuel and return fines and measuring a magnetic property of the sintered material, comparing this with a predetermined value corresponding to the desired properties, and where a difference occurs, adjusting -the fuel input' accordingly. A " magnetic index"  may be measured corresponding to the electromagnetic characteristic of a circuit including a coil with a core formed by continuously taken sample of sintered material, taken preferably from the output of the sintering stage. The sample may consist entirely of return fines. The control of the fuel content may be automatic. The sample may also be taken from the end of an auxiliary sintering process operating under corresponding -conditions to the main sintering apparatus. In Fig. 1, for example, ore from 1, return fines from 2, ore from 3 and water from 6 are mixed at 5. The mixture passes to main sintering strand 10 and after two screenings the magnetic properties of the fines are measured at 25. In this Figure an auxiliary sintering apparatus is not shown. Specification 1,255,801 discloses the use of magnetic measurement in addition to gas permeability measurement to control the process.
