Abstract: 348,824. Refrigerating ; raising liquids. ELECTROLUX, Ltd., 153, Regent Street, London.-(Assignees of Lenning, A. ; 2, Norrmalmstorg, Stockholm.) April 8, 1930, No. 11143. Convention date, April 9, 1929. [Class 29.] Absorption systems.-In a circulation system for liquids wherein vapour generated from the liquid serves to raise it through a capillary or small bore tube to a higher level, the upper part of the lift tube is sloped or shaped so as to diminish the effective pressure head of a liquid column in the tube, whereby tendency to back-flow is reduced. As shown in Fig. 5, the lift pipe 13 from a heated coil 12 communicating with the low-level vessel 10 slopes steeply in its lower part 16 and less steeply in its upper part 17, which may be in the form of a coil. The lift pipe may be formed to a continuous curve sloping away from the vertical, or it may have a bore increasing towards the top but still of capillary dimensions. The application to a continuous-cycle refrigerating system is shown in Fig. 7, in which a generator 20 with a central flue 21 heated by a gas burner 22 is provided with a "pumping" coil 12 continued upwards as an inclined straight pipe 16 and a coil 17 discharging into a chamber 24. This chamber has a central tubular baffle with apertures at the bottom through which the liquid flows into a pipe 23 back to the generator, while gas separated from the liquid passes on to the usual rectifier 27, condenser 29, and evaporator, not shown. The absorber 10 is fitted with apertured discs 38 and communicates with a gas heat exchanger 32. Strong liquor flows from the bottom of the absorber by a pipe 11 and interchanger 43 to the "pumping" coil 12, and weak liquor returns from the generator by pipe 44, interchanger 43 and pipe 46, to the top of the absorber. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the application of the modified lift-tube to circulating systems in which vapour is introduced into the liquid. This subject-matter does not appear in the Specification as accepted.

[Class 38 (v).] Flexible - pull actuation; interlocked switches ; contacts.-A switching device for connecting an X-ray tube to a high-tension circuit comprises stationary and movable contact members having surfaces with large radii of curvature, the movable contact members being attached to movably supported end sleeves of the high-tension cables. In one arrangement, Fig. 1', having overhead high-tension lines 1, 2, the cable end sleeves 11, 12 and movable contacts 13, 14 are carried by a rigid supporting member 15, and are raised towards or lowered from the fixed contacts 5, 6 by means of a flexible pull 18. In a modification, Fig. 2 (not shown) the switching operation is effected by rotating the supporting member. When the heating current for the cathode of the X-ray tube also flows through the switching device, the contact members on the cathode side are constructed as shown in Fig. 5. In this construction, a porcelain insulator 34, carrying two conductors 36, 37 connected to the cathode, is mounted at one end of a supporting piece 47 which is raised or lowered to effect the switching in or out of the X-ray tube. The upper portion of the insulator carries metal contacts 38, 39, of large radius of curvature, separated by insulation 40, the contacts being connected to the conductors 36, 37. In the closed position of the switch, the contacts 38, 39, engage metallic elastic rings 41, 42, which are insulated from each other and connected to conductors 44, 45 leading to the source of heating current for the cathode. These conductors are enclosed in a metal tube 46, which is in electrical connection with one of them and is also connected to one of the high-tension lines. In another arrangement, Figs. 7 and 8, the X-ray tubes are connected directly to the high-voltage source, comprising a Villard arrangement with transformer, rectifiers and condensers in a container 69 enclosed in an outer casing 48. The cables 49 ... 52 leading to a pair of X-ray tubes are furnished with end sleeves 55 .... 58, to which are secured metal balls 59 .... 62. The cable end sleeves corresponding to each tube are connected together by shafts 53, 54, either of which can be rotated to bring the balls carried by one pair of end sleeves into engagement with contacts 63, 64 connected to the high voltage terminals. Locking devices 65, 66 may be provided to prevent movement of the shafts unless the primary circuit of the transformer is interrupted. Pumps 73, 74 serve for the circulation of cooling fluid from the anodes of the X-ray tubes. Additional interlocks may be provided to prevent the energization of more than one tube at a time, or to prevent the filament voltage from being switched off while the tube is connected to the high voltage circuit.

Abstract: 1332205 Cathode-ray tube displays HEWLETT-PACKARD CO 26 April 1971 [11 May 1970] 11406/71 Heading H4T In an arrangement for tracing characters on a CRT in response to a sequence of digital instructions, each instruction specifies a straight-line vector by its end points (Xa, Ya, Xb, Yb) and in addition includes further digital data specifying the time to be taken over the trace so that the tracing velocity may be kept constant. As shown each character word is loaded in succession into 13 under control of a "ready" signal from 33 (which also over 55 advances the screen X position along the line, or shifts to the next line of characters over 55 and 57), and this addresses the first stroke in a read-only memory 19, thus reading out the X and Y start coordinates to 29, 30. The address in 19 is then incremented and the next X, Y co-ordinates read into 31, 32 (33 continues to order the alternate loading into these pairs of registers). At the same time a Z part of the stroke word is passed to 43, and this contains "length of stroke" data which is decoded and passed to 41 where it produces a ramp voltage of period corresponding to the length of stroke. This ramp voltage controls the speed of switching of the input of D-A converters 21, 27 (comprising current sources and a weighted resistor network) from registers 29, 30 to 31, 32. The outputs of the D-A converters are combined respectively with the character position outputs of 59 and 61, and passed to the CRT. The Z data also controls the unblanking of the tube beam, and provides an end-of-character signal at the last stroke to order the loading of the next character.
