Title: Improvements in and relating to suspended conveyors
IPC: F16H1/16
Filed: 1937-08-17
Abstract: 487,188. Endless -- chain conveyers. COWEY, L. E. Aug. 17, 1937, No. 22567. [Class 78 (i)] In conveyers of the kind in which trolleys each comprising a pendant arm are suspended on grooved wheels from a single overhead track and are driven by a chain arranged beneath the track and operated through worm and sprocket gearing from a source of power, each pendant arm is provided with means adapted to coact with the underside of the track rail to prevent displacement of the wheel therefrom. The track 2, Fig. 1, is of ovoid or streamline crosssection and is carried by horizontal arms 8 secured to supports 7. Adjacent lengths of tubing forming the track are butt jointed and connected by tightly fitting liners 9, Fig. 7. Each trolley wheel 3 is made from sheet steel in counterpart halves which are secured together by screw studs and nuts to form a peripherally grooved wheel with a perforated web 15 that houses the outer race of ball bearings 12. The trolley arm 4 is secured on the spindle 13 of the wheel 3 by a nut, and its lower end is secured to the upper part 6a of the load carrier 6 and to the driving chain 1 by a bolt and nut 19. The load carrier 6 comprises a pair of prongs on which rests the collar of a bottle neck. This carrier may be replaced by a ring 6, Fig. 3a, of metal, rubber, &c. which receives the discharge spout of a siphon head. A grooved guard roller 20 is mounted on the arm 4 and prevents displacement of the trolley from the track. Alternate links of the driving chain 1 are engaged by the bevelled teeth a of the driving sprocket A which is mounted on the driving shaft 30 by means of a sleeve 52 secured thereto by nuts 57. An adjustable slipping clutch between the sprocket A and the shaft 30 comprises a fibre ring 54 and a pair of annular plate springs 55, the tension of the latter being adjusted by moving an internally threaded disc 56 along the sleeve. The flanged end 53 of the sleeve bears against a tubular distance piece 53a, the upper end of which runs in the reduced end 40b of the tubular boss of the gear-box 40 and abuts the inner race of the ball bearing 32. An extension 33b of the hub of a worm wheel 33 also abuts this race, and is surrounded by a tubular boss 40a formed on the bottom of the gear-box and filled with grease. The wormwheel 33 gears with a worm 34, the shaft of which is connected 'through an Oldham, or other self-aligning coupling, to the shaft of a motor. Oil is fed to the worm gearing by a small worm wheel 60 rotatably mounted on a spindle 61. Flanges on the gear -box are secured to a cover 47 which is secured to an overhead support D. Webs 48 on the cover are integral with a tubular housing 49 which forms a grease box for lubricating the ball bearing 31 for the shaft 30. In a modification, the track is of circular cross-section and its bottom has a groove which receives a pin on the arm 4.

Abstract: 669,995. Telemotor systems. STARCK, G. P. B. Aug. 27, 1948, No. 22660/48. Class 69 (ii). In a telemotor system of the type comprising a transmitting member and a receiving member each including a hydraulic cylinder and a piston therein one element of each member, i.e. either the piston or cylinder being movable and the other stationary and a pump positively driven by the movable element of the transmitting member during predetermined portions of its strokes for supplying liquid to the system so as to compensate for leakage the movable element of the receiving member is positively stopped in a predetermined position during each operative stroke for defining one end of each such stroke and a relief valve is provided for permitting any surplus liquid to escape at a pressure above the normal working pressure of the system. As shown, fixed pistons 2, 4 co-operate with movable cylinders 1, 3 respectively. The transmitter cylinder actuates a piston 16 which pumps oil into the system and an adjustable stop 12 is provided to limit the stroke of the cylinder 3. When the pressure rises at the end of the stroke excess liquid, if any, is returned to the pump suction by a valve 21. The cylinder 1 is operated for instance by a cam (not shown) which co-operates with a roller 5. The return stroke is effected by fluid such as air under pressure. As shown, air under pressure from a tank 13 acts directly or indirectly (through the medium of oil) in a space 14 of the cylinder 3.

Title: Improvements in or relating to gasification of solid carbonaceous materials
IPC: C10J3/00
Filed: 1947-08-19
Abstract: 630,048. Induction heating. KOLLER, K., and ESZTERGALY, F. Aug. 19, 1947, No. 23016. Convention date, Oct. 26, 1942. [Class 39(iii)] [Also in Group XII] In an electrical process for the continuous gasification of solid carbonaceous materials such as coals and oil shales, the heat required is supplied indirectly by induction, the gasification occurring in an electromagnetic field by contacting the material with a gas containing combined but not free oxygen. In the form shown the apparatus comprises a casing 1, of an electrically conducting material such as cast iron or cast steel, enclosing a gasification chamber 2 and surrounded by an induction coil 3 embedded in a lining of an insulating material 4 and energised by alternating current. This causes induction heating of the casing which radiates heat to the charge therewithin; when thus heated the charge itself also becomes capable of being further heated by induction. A gas such as steam carbon dioxide or furnace gas, preferably preheated, is introduced into chamber 2 through openings 10 in the ash plate 12, a portion of the gas also entering at openings 8 after being further heated by passage through the spiral duct 6 in casing 1. To vary the composition of the final gas more steam &c. may be introduced through openings 5. The raw material enters the chamber 2 through openings 21, the producer or water gas leaving by openings 22. The gas entering openings 8 and 10 passes up through the bed at sufficient velocity to loosen the charge and cause the smaller particles at the top to circulate through and around a funnel-shaped body 25 supported coaxially in chamber 2, this body also being of electrically conducting material and being heated by induction.

Abstract: 1298190 Data transmission; polling BUNKER RAMO CORP 19 April 1971 [13 April 1970] 23106/71 Heading G4A [Also in Division H4] A digital electric device 16A-16N for generating polling messages to a plurality of addressable stations AO-AN in a predetermined sequence uses a table of station addresses received from a central processing unit 10. An interface 12 multiplexes signals from several such devices in both directions. The table of addresses is stored in a delay line, magnetic drum, or disc store 14, and device 16 recognizes a station address and polls that station over a telephone line 18. If the station provides a negative response the device selects the next address in the table and polls the next station. If the station produces a positive response this is stored in delay line 14, or, if a polled station fails to respond to a poll, or generates on error (e.g. parity or no replay received in a certain time), or the end of the table is reached, a response message is sent to CPU10. The CPU can then send a fresh table. Fig. 2 (not shown) shows a flow diagram for polling. This arrangement is stated to reduce the number of interrupts to the CPU and also simplify changes in polling sequence by changing the table. Also mentioned are diagnostic routines for errors, shift registers, and erasure of polled addresses in the table.

Plants, treatment of growing.-In the separation of carbon dioxide from gases containing it by absorbing it in a liquid and subsequently freeing it by means of heat, carbon dioxide substantially free from steam and sufficiently pure for use in a green-house is produced by employing the same current of air for condensing the steam and for conveying the carbon dioxide through the apparatus. In the apparatus shown in the Figure, heat from a furnace 1, which is also the source of the carbon dioxide, is used to drive off the latter from the saturated liquor collected in the boiler 8 from the packed absorption chamber 2. The mixture of carbon dioxide and steam passing through the condenser 10 is cooled by the same current of air employed to entrain the substantially dry carbon dioxide leaving the pipe 14. Condensed steam is returned to the boiler 8.
