Abstract: 737,300. Thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 27, 1953 [July 30, 1952], No. 20771/53. Class 39(1). An electrode system is supported from the envelope by means of a mica spacer whose edges consist of arcs which make obtuse internal angles at each intersection. Mica disc 5 has its edges formed by four arcs of radius Rc, preferably 20-30 per cent greater than Rb, the internal radius of that part of the envelope with which the mica engages. The diameter of the mica from corner to corner is at least 0.5 per cent greater than 2 Rb and the tolerance of Rb is less than 0.33 per cent. Elongated micas may be obtained by varying Rc for two arcs located opposite each other. Each electrode may alternatively have a separate mica support.

Title: Improvements in and relating to coin freed dispensing machines for liquids
IPC: G07F13/02
Filed: 1932-08-11
Abstract: 405,963. Coin-freed liquid-delivery apparatus. HIGHT, G. F., 26, Blockley Road, North Wembley, and WEBB, C. H., 22, St. Mary's Crescent, Hendon, both in Middlesex. Aug. 11, 1932, No. 20849. [Class 27.] A removable reservoir 5 is held in an inverted position in a casing 1 by a support 7, closed by a rod 8, and by a cup 6 held by spring clips 16. The reservoir neck 11, Fig. 4, is closed by a removable spring-pressed valve 13 bearing against a seating 12 till inserted in position, when the valve 13 is raised by the abutment of its head 15 against a plug 17 fixed to the cup 6. Liquid from the reservoir can then pass the valve 13 and enter a pipe 19 through an aperture in the plug 17, the cup 6 remaining full up to the level of the valve exit 10. The pipe 19 is connected to a manually operated 3-way cock 28, Fig. 6, whereby it may be put into communication with a preferably removable measuring chamber 26, Fig. 5, provided with a small bore vent tube 38. The chamber 26 is visible through a window 41, and by turning the handle 29 through approximately a right angle, the cock 28 allows it to discharge its contents through pipes 24, 25 to a delivery nozzle over a drip catch. A spring 32 fixed to a disc 33 on the cock 28 returns the latter on release to put the reservoir 5 and chamber 26 again into communication. Spring-pressed paper cups can be removed through an opening 58, and after use can be deposited in a bin 60 through an opening 59. Coin action, weight.-The coin slides down a chute 43 to fall on a lever 46 pivoted at 47 and having a rear extension carrying an adjustable balance weight 49 and also forming a projection 50 which engages a recess 51 in the disc 33. The weight of the coin tilts the projection 50 out of engagement with the disc 33, thus freeing the handle 29 for actuation, and until actuation occurs the lever 46 rests on an arm 52 projecting from the disc 33. Testing coins and fraud preventing.-The chute is provided in its length with a slot 44 through which undersized coins are rejected, and has at the bottom a sharpened or serrated edge which cuts a string &c. by which repeated actuation by one coin may be attempted. Coin - discharging mechanism; exhibiting coins.-The coin after actuation falls on a counterbalanced platform 54 where coins accumulate until the platform is tipped by their weight and they fall into a receptacle 55. A window 56 allows the last inserted coin to be seen.

Abstract: 1488468 Change-speed control; linkwork JSJ CORP 20 May 1976 [21 May 1975 4 Sept 1975] 20939/76 Headings F2D and F2K Levers 50, 70 pivotally mounted at 52, 72 on a pin 32 are operated in succession by a selector plate 20 rotatable by a shaft 40 actuated by a lever 30. The levers 50, 70 have elongated holes 54, 74 to clear the shaft 40 and follower pins 57, 77 received in cam slots 24, 23 in the plate 20, the latter having a neutral position in which each pin 57, 77 lies at the mid point of its respective slot. The slot 24 is so shaped that the first part of the movement of the plate 20 in either direction from its neutral position actuates the lever 50, whereafter further movement of the plate brings a dwell portion 29 or 31 into engagement with the pin 57 so that no further movement of the lever takes place. The slot 23 has a dwell portion 25 corresponding to the first part of the movement of the plate and operative portions 26, 27 such that the lever 70 is displaced in one direction during the second part of the movement of the plate 20 in either direction. The apparatus is for controlling an interaxle transfer box of a four wheel drive vehicle, the lever 50 selecting high or low ratio and the lever 70 locking the differential. Notches 64, 65 engaged by a spring-loaded pin (not shown) locate the plate in the positions corresponding to selection of high or low ratio but before displacement of the lever 70 to lock the differential. Holes 56, 33, 76, 66 receive an alignment pin for initial setting up. In a modification the cam slots are formed in the levers and the selector plate, formed integrally with the lever 30, carries the follower pins.

The coal is charged into the hoppers 2 containing oscillating agitators 14, passes through the retorts and is discharged through the opening between reciprocating plates 15, Fig. 7, supported upon rollers 16. The gases generated in the retorts pass through the vent pipes 7 or the spaces between the H-section plates to the headers 10. The flues are heated by hot gases which pass in a zig-zag path from the lowest to the highest of the flues before exhausting to the chimney. Dampers may be provided to by-pass the hot gases into the spaces 26 between the retorts, such spaces communicating through the outlets 12 with the headers 10. In a modification, gases are burned in the lowest flue 30, Fig. 16, and auxiliary burners 32, 32', 32" are located in alternate flues. The apparatus may be combined with a bunker containing wet coal with which the heated coal is mixed.

Preferably these proportions fall within the ranges 38-42 per cent, 15-48 per cent, 11-45 per cent respectively and the proportion of cerium is between 0À05 and 12À5 per cent of the halophosphate. Up to 10 per cent by weight of the calcium and/or strontium, calculated as calcium alone, may be replaced by manganese. The material may include one or more of the alkali metals lithium sodium or potassium, e.g., as a carbonate or chloride in a proportion of up to 10 per cent by weight of alkali metal in the material. The materials may be made by heating at 900‹-1200‹C. a halophosphate matrix or a mixture of materials that will yield the halophosphate matrix on heating (e.g., Ca HPO 4 , CaF 2  and (NH 4 ) 2  HPO 4 ) together with compounds which will on heating incorporate the cerium or cerium and manganese activators in the matrix. Examples are given of firing at 1120‹C.-1150‹C. for three separate periods of half-hour each in a closed silica crucible. The materials when excited with ultraviolet light of 2537‹A wavelength emit luminescence ranging from ultra-violet to pink depending on the starting materials and their relative proportions,
