Abstract: 1,129,076. Fluid heaters. FOSTER WHEELER CORP. 28 April, 1966 [11 June, 1965], No. 18729/66. Headings F4A and F4S. A process fluid heater has rows of vertical tubes 41 extending through an enclosure 21 into which burners 31 fire, the gases from the enclosure 21 then passing over convection heated tubes 27. The tubes 41 are supported by a weight and pulley arrangement 49 from frame 53, and are supplied with fluid from upper header 50 through connectors 58, 60. The tubes 41 are provided with removable end caps 47, through which catalyst (54, Fig. 5) and catalyst support cones (51) may be inserted. From the tubes 41, the fluid passes through connectors 55 to a horizontally extending lower collector header 42, which is mounted in a support casting 44 by a bracket and slot arrangement (48, 46, Fig. 2) to permit longitudinal expansion of the header. A metal bar 61, having expansion rate similar to that of the header 42 is placed parallel thereto in contact with and between the tubes 41, a little above the point of connection of the connectors 55 to the tubes. This expands as the header does, thereby bowing out the tubes 41 at their lower end, and preventing the connectors 55 from breaking. The bar is formed from a plurality of half sections 63, Fig. 3, each section engaging four of the tubes, the sections being bolted together at their edges. The sections associated with each row of tubes, are cross linked by members 73, to form the bar 61 which is maintained in place by spaced lugs (77, Fig. 2) on the tubes. In a modification (Figs. 5 to 8) provided with a single row of vertical tubes, the bar (61) is formed from two overlapping half bar sections (81).

Abstract: 1,051,419. Cameras and cartridges therefor. AGFA A. G. Feb.28, 1964 [Sept. 30, 1963], No. 8480/64. Heading G2A. A film cartridge or cassette has an external feature or mark mechanically explorable by a member in the camera itself, the mark being indicative of the film sensitivity, and the member automatically adjusting an exposure-regulating device in the camera accordingly. In the form shown, the cartridge 4 has a flattened surface 7 on which is a pin 9 near one end thereof. The distance between pin 9 and the edge 8 of the flattened area 7 is a measure of the sensitivity of the film. On inserting the cartridge into the camera 1, pin 9 comes up against a feeler element 12 loaded by a spring 18, and pushes it back  against the loading. The element 12 is part of a lever system 14, 20, pivoted at 19, and the other end of lever 20 has a toothed end 21 meshing with a pinion 22. This rotates a moving coil galvanometer forming part of the exposureregulating device, whose setting is thus altered according to the position of pin 19, i.e. the film sensitivity. Various alternatives to the pin 9 are shown in the other Figures, some of which are adjustable, such as a rotatable disc Fig. 5, (not shown), or a clip having a projection which engages feeler 12. Such clips may advantageously be attached after the cartridge has been loaded with film.

A bed 7, Fig. 1, or other wheeled load, is pulled into a lift car 3 by a carriage 8 which is propelled by a plate chain 9 driven by an electric motor 13 in the lift. The chain is guided round sprockets 12 in the lift and the bed is guided by rails 16. Photo-cells 29 sense the presence of the bed and automatically summon the lift car and control the loading sequence. The lift is open fronted and each landing has a vertically sliding door 6. The carriage, Fig. 3, has arms 19, 20 which are in the position illustrated when the carriage is moved out to engage a bed. As the carriage moves forwards a sensing finger 22 contacts a rod 7.2 on the bed frame and is pushed back flush with the face 19.21 of the arm 19. This operates a switch which energizes an electromagnet and raises the arm 20 against a return spring, and stops and reverses the chain driving motor 13. The bed is now drawn into the lift, the door closes and the lift moves to the preselected floor. The reverse procedure is followed when the bed is unloaded. Figs. 5, 6 (not shown), illustrate an embodiment in which a single electromagnet operates both arms instead of a separate electromagnet being provided for each.

Abstract: 1,258,980. Controlling burners. DANFOSS A.S. 9 July, 1969 [13 July, 1968], No. 34594/69. Heading F4T. [Also in Division H2] An A.C. powered burner control circuit comprises a D.C. operated relay M, bridged by a rectifier D1, contacts F2 of a photo-electricallyoperated relay F, bridged by a resistance R1, and a heating coil V for a thermally-operated time-delay switch V1, arranged in series, the relay M having contacts M1 operating a motor 5 supplying fuel-oil to a burner, and the bridging resistance R1 being so rated that, when contacts F2 are open, the current flow is sufficient to maintain the state of relay M, but insufficient to actuate relay M or switch V1. A thermostat KT supplies power to the circuitactuating relay F, contacts F2 then actuating relay M and starting motor 5, and contacts F1 supplying current to an ignition transformer 8 supplying a spark igniter. If ignition occurs, a photo-resistor 9 makes a transistor Tr conduct, tripping relay F and thus disconnecting ignition transformer 8, and reducing the current through relay M and coil V, without shutting off motor 5. If ignition fails to occur, coil V heats sufficiently to switch contacts V1, lighting an indicator lamp 6 and cutting off the power to the device until, after cooling, switch V1 returns to the illustrated position, initiating a further ignition cycle. If the flame should go out, relay F trips, starting a further ignition cycle.

Abstract: 1,264,400. Endless conveyers. W. G. SCHULTZ. 19 Nov., 1969 [16 Jan., 1969], No. 56672/69. Heading B8A. An extendible conveyer 10 used in a mine passageway 17 comprises a storage unit 11, a drive unit 12 and a tail terminal unit 13, all the units supporting an endless belt 14 on to which material from a boring and loading machine 15 is fed. As the machine 15 advances, a belt storage section 21 allows the belt 14, where it passes around a drum 50 of the loading machine, to move with the machine. The drive unit 12 comprises drums 33, 34 and is provided with a shoot 40 for transferring material from the belt 14 to a conveyer (42), Fig. 1 (not shown). The storage unit 11 comprises a pressure-sensitive winch (67) connected by a cable (80) to a carriage 74 for a belt drum 77. The carriage is slidable on cables 73 secured to the units 11 and 12. Both units have skids but are normally secured to the floor. As the loading machine 15 moves away from the drive unit 12 the winch (67) permits restrained movement of the carriage towards the unit 12 and, although extra belt is provided from the storage section 21, correct tension on the belt is maintained. For additionally supporting the belt, a number of roller units 81 are removably located in the floor. In a modification, Fig. 4 (not shown), the material is transferred directly from the conveyer (10) on to a conveyer (42<SP>1</SP>) at rightangles thereto.

A valve 37 with a straight passage 40, mounted between valve seats 41 in a chamber of a female element 11 of a disconnectible pipe coupling, is operated by a sleeve 35 slidable on the female element, and when in the open position, its passage is aligned in a straight flow path with the chamber inlet and outlet, and the passage 15 of a male element 10, coupled to the female element. The sleeve 35 operates a pin 43 in a transverse groove 42 in the valve 37, adjacent to one end of the valve, so that axial sleeve movement opens or closes the valve. In the uncoupled position, the sleeve 35 is retracted and rotated so that the pin 43 is locked in a transverse aperture (46) in the female element body, Fig. 4 (not shown); also locking balls 34, held in tapered holes 33 in a socket part of the element 11 are aligned with corresponding grooves 36 in the sleeve end, so that the male element 10 can enter the socket. The sleeve 35 is then rotated so that the pin 43 emerges from the aperture (46) and the grooves 36 are rotated away from the balls 34, locking the balls into a groove 17 in the male element. The sleeve then moves axially with the pin 43 sliding along the axial margin (45) in the body of element 11, opening the valve 37, and the sleeve is rotated to lock the pin into another transverse aperture (47). Though in this position, the grooves 36 are aligned radially with balls 34, the sleeve axial displacement causes the balls to -be positioned beyond the groove inner ends. The procedure for valve closure and subsequent uncoupling is a reversal of the above procedure. A passage 50 is provided in the valve 37 for pressure relief, which communicates the male element passage 15 with the atmosphere when the valve is closed.
