Title: Automated chemical analyser
IPC: G01N35/10
Filed: 1969-01-21
Abstract: 1,224,863. Automatic analysis apparatus; analysis filter. BECKMAN INSTRUMENTS Inc. 21 Jan., 1969 [22 Jan., 1968], No. 3397/69. Headings B1D and B1X. Capsules 24 (Figs. 7, 8, not shown) are fed individually by a mechanism 28 (Figs. 13, 14, not shown) on to a horizontal transporter 22, 26 which feeds them progressively from left to right in Fig. 1, a rotary turntable 32 carrying a series of sample-containing test tubes (Figs. 15, 16, not shown) presenting each in turn to a probe (243), which withdraws the sample and then moves laterally (mechanism 30) and expels the sample into compartment (116) of the capsule. As the capsule moves to the right, it passes device 40a, which adds a precipitant to the sample, then dispenser 34 (Figs. 11, 12, not shown) drops a filter cup (Fig. 9, not shown) into compartment (116) and suction device 36 draws filtrate through the upper base into the cup. Device 38 (Fig. 17, not shown) withdraws the filtrate into a probe (328), which moves laterally and discharges it, followed by a quantity of water, into another compartment of the capsule. Subsequent devices 40b..40n add colour developing and arrest reagents to the filtrate, which may be heated at this point by an incubator block 400, shaped to fit round the capsule compartments during its raised periods. A probe (354) (Fig. 18, not shown) picks up the colour-developed sample and conveys it through colorimeter apparatus 50, then an array of probes (374) empty all the compartments of the capsule, which moves off the right-hand end of the transporter for disposal, together with its filter cup. The ends of the capsules rest on rails 22 which are moved up and down by pneumatic ram 80. On each down movement, each capsule engages over a pair on teeth on racks 26, which are then moved rightwards by pneumatic ram (90), sliding the capsules one step along the rails 22, which are then raised while racks 26 move leftwards, in preparation for the next step. Most of the time capsules 24 are held in their raised positions, and the various operations described above are all intitiated by the capsule lifting operation, engagement of the capsule with a microswitch closing an electric circuit, triggering a flip-flop which controls the pneumatic ram controlling the operation in question. Some operations use several rams, each triggered by completion of movement of its predecessor or by a timer, (Fig. 19, not shown). Turntable 32 is raised by its ram (270) to immerse probe (243) into each test tube in turn, and is rotated by a ram (290). The number of reagent adding devices may be varied and they incorporate compressed air nozzles (392) (Fig. 10) to agitate the liquids. The various probes are connected to reciprocating pumps whose actions are similarly controlled to those of the rams, and the adding devices involve similar arrangements to deliver predetermined quantities of liquid.

Cutting-edges, treating; disc and wheel apparatus; processes, special; wheels and other tools.- -Knife blades and other articles are ground by traversing them, while submerged in an abradent carrying liquid, across a rotating soft non-abrasive member. For knife blades the polishing may be done in three stages, the rotating member being driven at a lower speed during the second stage. and a felt' rubber and a finer abradent being used for the final operation. A bath 14 containing water carrying a relatively small amount of flotative abradent, e.g. about 20 per cent, is mounted on a carriage 10 reciprocated on rollers 9 through crank mechanism 41, 40, 39. The blade Kb is secured inside the bath by a magnetic chuck 16 carried by a ledge 15. The power shaft 39 through gearing 37, 35, 34, 30, 29 drives a pulley 28 splined to a shaft 19 urged downwards by an adjustable spring 23 and thrust washer 25. To the lower end of the shaft is secured an annular member of birch wood or other substance. In order to suspend the polishing while the direction of motion of the blade is changing a cam 42 on the carriage actuates a bell-crank 43, 44 to relieve the pressure of the spring 23. When a mirror finish is desired 4F emery is used for the first two stages and "Chromotron" for the third stage.

Patent GB-1486544-A (GB)
Title: Production of containers
IPC: B21D51/26
Filed: 1976-02-02
Abstract: 1486544 Making hollow bodies; necking; flanging NATIONAL CAN CORP 2 Feb 1976 [3 Feb 1975] 03981/76 Headings B3A B3Q B3E and B3J Aluminium can bodies &c. 30, Fig. 3, are necked and flanged in apparatus in which they are moved, along a horizontal path with their axes vertical, to a necking station 24 where an annular die forms the nesk, and then to a flanging station 26 where freely rotatable rollers form an outwardly-turned flange. An endlessbelt conveyer 38 delivers the bodies 30 to a feed screw 40 for conveying them past a lubricating or waxing station 22 where lubricant is applied to the upper, free edges. A star wheel 42 transfers the bodies to a turret mounting the necking dies from which the bodies are transferred by a star wheel 52 to a further turret 26 where they are flanged. A further star wheel 60 replaces the flanged bodies on the conveyer 38. The areas below the star wheels 42, 52, 60 have vertically adjustable hardened wear plates. Drive for the machine is through gear-boxes and a belt 509 from a motor 500, although a separate motor (580), Fig. 1 (not shown), and a chain (584) may be used for the conveyer 38. A turret may be adjusted relatively to its driving gear 520, Fig. 8, by releasing clamping bolts 530 and turning the turret by screws 524 bearing on a projection 522 from the gear 520. Lubrication is effected by four brushes 70, Fig. 4, past which the bodies are rotated by contact with a driven band 112 at one side while bearing at the other against a stationary rail 110. Lubricant is supplied to the brushes 70 through conduits 104 from a manifold 102. The brushes are adjustably carried by a shaft 82 which may be turned by a fluid ram 96 to place them over a trough 98. Necking is caused when a respective support 194, Fig. 5, is raised as the turret 24 rotates about a stationary cam track 196 on which bear followers 197, 198 carried by the support 194. Ejection of the necked body from the necking die 178 is by compressed air assisted, if necessary, by a plunger 200 operated by a stationary cam track 214. Compressed air is supplied to a channel 224 from which it passed to ports 228 in a member connected by conduits 230 to axial bores in the plunger shafts 202. Flanqing by flanging heads carried by the turret 26, Fig. 7, occurs when rotation of the turret causes supports 324 to be raised by a stationary cam track 329 on contact with followers 326, 327 on the suuports. The flanging heads mount pinions 342 meshing with a stationary gear 340 so that they rotate on their own axes as the turret rotates. Freely rotatable rollers 384, Fig. 10, on the flanging heads form the flanges. A vacuum applied to the supports 324 through conduits 410, 418, Fig. 7A, strips the flanged container from the rollers 384 when the supports are lowered.

Filed: 1939-02-07
Abstract: 526,104. Turbine-driven aircraft. BAYNES, L. E., and MUNTZ & CO., Ltd., A. Feb. 7, 1939, No. 4055. [Class 4] [Also in Group XXVI] An aircraft has a plurality of airscrews and gas turbines, a separate turbine being associated with each airscrew to form a unit mounted on the wing, and conduits connecting one or more gas generators housed in the fuselage to each of the turbines. In the form shown in Fig. 1, two banks of gas generators, for example of the kind described in Specification 515,457, mounted in the bottom of the fuselage 11 have upper and lower manifolds 25 for the supply of compressed air, and a manifold 19 leading the combustion products to a vertical conduit 20 having branch conduits 21 supplying the turbine units which are arranged in casings 17 in the wing. Valves 29, 30 regulate the supply of gas to the port and starboard sides. Each unit comprises an airscrew 16 driven by a turbine through gearing in the casing 17, an auxiliary turbine driven by the exhaust of the main turbine operating a blower which draws in air from the front of the casing and delivers it under pressure to a branch conduit 22 of conduits 23 in the wing, and deliver it through a vertical conduit in the fuselage to the headers on manifolds 25 of the generators. The turbines operating the blowers exhaust to atmosphere and operate more quickly as the external air is more rarified. The air for the generators may be produced by turbine-operated blowers arranged in the fuselage. Auxiliary turbines are provided in the fuselage for generating electricity, for filling a compressed air storage bottle for starting the gas generators, and for supplying compressed air for the fuselage, which may be of the kind described in Specification 526,105. The fuselage 11 has transverse bulkheads 15, and longitudinal girders 13, 14 and contains the generators and other machinery that may require attention during flight. The gas generators are coded by fluid passing through flow and return passages 27, 28, Fig. 6, in the leading edge of the wing, which is thus de-iced. In the form shown in Fig. 8, gas generators 77 are arranged in a watertight fuselage 70, the upper part of the fuselage being provided with tanks for water, fuel, oil, and coolant. The fuselage also contains an air reservoir for starting. The gas is passed through a conduit in a short wing 71 to turbine units mounted in casings 72 pivoted about trunnions 73. The casings carry the land wheels 76 and have watertight compartments, so that the aircraft can alight on water. In the position shown, the aircraft acts as a helicopter. When the aircraft is in the air, the units are rotated to bring the axis of the.propellers in line with the longitudinal axis of the aircraft, which then acts as an aeroplane. The blades 75 of the airscrews are pivoted on their hubs. Specifications 157,927, [Class 4], and 493,439 also are referred to.
