Patent GB-479248-A (GB)
Abstract: 479,248. Solid-fuel stoves. SVENSKA AKTIEBOLAGET GASACCUMULATOR. March 8, 1937, No. 6785. Convention date, March 7, 1936. [Class 126] In a continuous combustion stove for solid fuel, the walls of the ash-pit 11, Fig. 1, are insulated against the outward radiation of heat so that immediately beneath the grate 7 there is a heatinsulated space in which the combustion air is preheated by radiation from the firebox, and the total area of the grate surface formed by the spaces between its bars is at least twice, preferably three times, as large as the total area of the grate surface occupied by the bars, so that heat transmission through the grate is facilitated. The grate, which may be made ot a chromium-iron alloy, bulges downwardly at the centre and rests by narrow projections 9 on ledges 10. A ledge 12 constricts the firebox above the grate. A thermostatically actuated valve 15 controls the air supply. The walls of the ash-pit and firebox may be integral or connected by heat-conducting material, to facilitate the passage of heat to the ash-pit. The Specification as open to inspection under Sect. 91 describes also passing the air in contact with the outsides of, or through ducts 14 in. the walls of the ash-pit 11, Fig. 3 (Cancelled). Fins 18 are provided. An insulating member 19 separates the walls of the ash-pit and firebox. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,057,140. Masted lift trucks. EATON YALE & TOWNE Inc. Dec. 5, 1963 [Jan. 9, 1963; Feb. 27, 1963], No. 48050/63. Heading B8H. In a lift truck, a load carriage 14 is raised on the mast, which comprises fixed primary uprights 11 and slidable secondary and tertiary uprights 12, 13, and the mast is extended by an hydraulic ram 15 having a cylinder 17, which is movable vertically relative to the mast, and a telescopic piston 18, 19. Chains 16 extend from anchorages on the carriage 14, and pass around sheaves 20, 21, supported on brackets 26, 24 mounted at the top of the piston 19 and adjacent the lower end of the cylinder 17 respectively to brackets 22 adjacent the tops of the uprights 11. The brackets 24, 26 are provided with guides 25, 27 which slidably engage guide rails on the uprights 12, 13 respectively. In operation, initial extension of the ram 15 raises the carriage 14 at twice the speed of extension of the ram until the guides 27 engage stops 28 adjacent the top of the tertiary uprights 13, Fig. 9 (not shown), whereupon the uprights 13 are raised at the speed of extension of the ram and the carriage 14 continues to rise at twice the speed of extension of the ram until it engages stops 29 secured to the tops of the uprights 13. As the uprights 13 are initially raised, a latch member 30 thereon automatically engages the bracket 26 to lock the piston 19 to the uprights 13. After the carriage 14 has reached the top of the uprights 13, further extension of the ram raises the carriage 14 and uprights 13 as a unit and raises the ram through the chains 16 and sheaves 21. Upward movement of the ram raises the secondary uprights 12 through engagement of the guides 25 on the ram with stops 31 at the lower end of the uprights 12. The uprights 13 now rise at the speed of extension of the ram plus the speed of upward movement of the ram cylinder, while the uprights 12 rise at the speed of upward movement of the ram cylinder. Further extension of the ram causes the uprights 13 to pick up the uprights 12 through engagement of stops 32 adjacent the lower end of the uprights 13 with stops 33 at the upper end of the uprights 12. In a modification (not shown), the stops 31 on the uprights 12 are omitted so that the uprights 12 remain stationary until they are picked up by the uprights 13. The latch member 30 is held in the non-latching position, when the uprights 13. are fully lowered, by engagement with the top of uprights 11 and is spring-urged into latching engagement with the bracket 26 on the ram piston 9 when the uprights 13 are raised.

Abstract: 1,247,889. Navigational computers. CANADA, NATIONAL DEFENCE, MINISTER OF. 15 Oct., 1968 [23 Oct., 1967], No. 48910/68. Heading G4G. [Also in Division H4] An aircraft Doppler ground speed and track vector OX is corrected for the effect of surface motion of the sea by a device in which the track angle correction XOZ is obtained by inserting into an algebraic summer 14 the (estimated) surface wind angle and the Doppler track angle, feeding into a sin/cos resolver 15 the output of the summer and the (estimated) surface motion speed XY, and dividing the quantity XY sin X#YZ = ZX, on line 18, by an estimated magnitude OY to give the track angle correction XÈZ on line 23; angle XÈZ and the Doppler track angle are combined to give the corrected track angle. The invention   assumes that XÈY is, as in practice, very small. In the embodiment an electric analogue input of Doppler track angle is inserted at CX, is converted by conventional servo loop 12 to a shaft rotation and summer 14 utilizes a mechanical differential. Resolver 15 may be a potentiometer or a synchro resolver and its second input is controlled manually and proportionally to surface motion speed. Ground speed is followed by a potentiometer IS/TX and is added as a bias to servo amplifier 20. Magnitude XZ, on line 18, is divided by a selectable resistor 22 (or an equivalent potentiometer) in accordance with ground speed indicator 20a.

Abstract: 1359877 Hydrogen-carbon oxide mixtures PULLMAN Inc 26 Oct 1971 49766/71 Heading C5E In a process for producing mixtures of hydrogen and carbon oxides by partially oxidizing a hydrocarbon-containing feed and then catalytically reforming the partially oxidized gas mixture the partial oxidation is performed in a mixing and combustion zone into which the hydrocarbon feed is passed at a hypothetical longitudinal velocity of 15-60 feet per second and oxygen containing gas is concurrently introduced along the longitudinal axis of the zone at a longitudinal velocity of 4 to 16 times the hypothetical longitudinal velocity of the hydrocarbon feed and the hydrocarbon feed flows through the zone so as to surround the faster moving oxygen-containing gas so that the oxygen-containing gas penetrates the slower moving hydrocarbon feed and a stable flame is maintained. Hydrocarbon feed, which can be a partially reformed mixture derived from natural gas, refinery gas, liquid petroleum gas or naphtha, is passed into the zone 21 tangentially via the conduit 1 at 400-1000‹ C. Oxygencontaining gas (e.g. air + steam) at 600- 1600‹ F. is passed into the zone 21 via the conduit 5, suitably in a molar ratio of oxygen to hydrocarbon of 0À02-0À2. The partially oxidized mixture in which, e.g. up to 70% of the hydro. carbon feed has been converted to hydrogen and carbon oxides is passed into the catalytic bed 31, e.g. after a residence time of 0À05-2 seconds in the zone 21. The catalyst bed suitably comprises iron, nickel, cobalt, an oxide of one of these, or molybdenum oxide and can have a top layer of chromia catalyst. The exit gas 19 can have a pressure of 100-1000 p.s.i.g. and a temperature of 1100-2000‹ F.

A third track (C), Fig. 6 (not shown) may be provided on the record tape (36) with control signals whereby the effect of tape elongation and tape speed variations on the reproduced sound may be corrected. The sound may be recorded by frequency modulation as variations in tape thickness in lateral stripes (36). Variations in phase on reproducing the sound image may be converted to variations in amplitude by a quarterwavelength phase-shift plate (41). The record tape is produced using photo-resist and hot pressing methods.
