Title: Improvements in tungsten-rhenium alloy filament lamps
IPC: H01K1/08
Filed: 1965-05-26
Abstract: 1,053,020. Alloys. GENERAL ELECTRIC CO. May 26, 1965 [ July 8, 1964], No. 22357/65. Heading C7A. [ Also in Division H1] A lamp filament is made from tungsten which contains grain-growth-promoting additives, such as aluminium, potassium and silicon, and is alloyed with rhenium in amounts of from 0À1% to 7% by weight of rhenium, the filament having a metastable grain structure comprising a mixture of equiaxed grains of a size substantially less than the diameter of the filament mixed with elongated grains. During the life of the lamp the grain structure changes to one consisting predominantly of more elongated grains. In one method of treating the filament during lamp manufacture to develop the required grain structure, the filament wire wound on its mandrel is first passed through a tubular electrical annealing furnace at a speed of 22À5 feet per minute. The furnace has a hot zone about 20 inches long and a temperature of 1500‹ C., and contains an atmosphere of wet hydrogen which cleans the wire as it passes. The mandrel is then cut into sections carrying filaments of the desired length and the sections are placed in tungsten trays and pushed into an electric tube annealing furnace for two further heat treatments each of 10 minutes duration. The first treatment is at 1130‹ C. with a wet hydrogen atmosphere and the second is at 1500‹C. with a dry hydrogen atmosphere. The mandrel sections are then dissolved out in known manner and the filaments are mounted and sealed in glass lamp envelopes. The development of the crystal structure is completed by "flashing" the filament for six successive periods of two seconds. In a lamp designed to be run at 120 volts, flashing voltages of 130, 150, 150, 175, 175 and 150 are employed.

Title: Improvements relating to automatic controlling means for hydraulic presses
IPC: B30B15/16
Filed: 1947-08-15
Abstract: 631,908. Hydraulic presses. TALLIS. C. E. Aug. 15, 1947, No. 22692. [Class 69 (ii)] In a hydraulic press operated by a variabledelivery swash - plate pump such as the press described in Specification 614,132, the means for controlling the action and determining the time interval for which the pressure exerted is to be maintained comprises a body h having coaxial bores m and n with pistons o and p respectively, a spring q intermediate the pistons, a spring-loaded plunger r associated with the piston p and means for controlling the flow of liquid to and from the bores, the plunger transmitting movement from the piston p to the swash-plate c to effect retraction of the press. The ram when ascending uncovers a port, Fig. 1 (not shown), and the liquid actuates a plunger g to move the swash-plate c to the horizontal position. The liquid displaced.by the plunger g passes into the bore m at a rate determined by a valve s and moves the piston o down until it is checked by a shoulder. The spring q forces the piston p and thus the plunger r down at a rate controlled by a valve y which determines the pressure interval. When a port 5 in the plunger r is uncovered, the liquid beneath the piston p is exhausted and the spring q actuates the plunger to reverse the pump. The plunger r is returned by a spring 7, and liquid enters the bore n through a suction valve x whilst the piston o is urged up under the control of the valve s.

Class 7(5) In a two-directional engine - starting apparatus including two pairs of clutch elements 23, 28 and 24, 29, Fig. 1, one element 23, 24 of each pair being carried by a driving clutchmember, such as collar 22, and the other by a driven clutch - member 25 the arrangement being such that rotation of a driving shaft 2 tends to bring one or other pair of clutches into engagement by relative axial movement between members 22 and 25 whereas after starting the overrun causes disengagement of the appropriate pair of clutches, and a slip coupling, for example two or more centrifugally actuated levers 34, Fig. 2 which exert a frictional drag on the collar 22, Fig. 1, so that rotation of a shaft 11 in one direction or the other causes the collar to move in the corresponding direction due to the drag exerted by the levers 34, Fig. 2, there is provided a manually-controlled stopmechanism, such as a lock 44, having two operative positions in which it limits the relative axial movement of the members 22 and 25 in one direction or the other to prevent engagement, when the overrun occurs, of that pair of clutches which is arranged to transmit motion in the opposite direction to that in which the engine is being started. The shaft 1, which is driven by a starting motor, not shown, is connected by a worm 2 and a worm-wheel 3 or other reduction gearing to a hollow driven-shaft 4 in a stationary casing 7; within shaft 4 is the hollow starting-shaft 11, one end of which is connected by a multi-plate friction-clutch 14 to a flange 8 integral with the shaft 4. The collar 22 is connected by threads or helical splines 17 to the other end of starting-shaft 11 whilst the driven member 25 surrounds the collar 22 and is coupled to a turbine rotor 51; the levers 34, Fig. 2, are pivoted to the member 25 by bolts 33 and one end 35 of each lever is formed as a shoe to exert a frictional drag on collar 22 whilst the other end is acted upon by a spring 36; movement of the collar 22, due to the action of the levers 34, is limited either by a ring 18, Fig. 1, or the end 20 of a sleeve 21, whereupon one of the two sets of clutch teeth is engaged. The lock 44 may be moved into one of three positions by a lever 42 and a rod 37 to protrude through shaft 11 and prevent the movement of the collar from the central position or to enable it to be moved only to the left or right from the central position. A switch mechanism, not shown, controlling operation of the starter motor in either direction is conjointly locked or operated with the lever 42. The friction clutch 14 may be set to slip when maximum torque is being transmitted. The central position of rod 37, lock 44, and hence collar 22 may be dispensed with and more than one lock may be provided; the driven clutch-member may be axially slidable on a fixed driving clutch-member.

Filed: 1961-06-27
Abstract: 969,341. Lubricating devices. SHIBAURA KYODO KOGYO KABUSHIKI KAISHA June 27, 1961, No. 23275/61. Heading F2A. A lubricating system comprises a number of primary lubricating or distributing devices 3 to 8 each of the same construction, the outlet of the last device, e.g. 8, being connected to the inlet, e.g. 48, of the first of a number of secondary lubricating devices 11, 14, and 15. The primary unit 8 for example comprises parallel cylinders 19, 20, 21 with multi-land type piston valves located therein. The cylinders have pairs of outlet ports 22, 23, 24, 25, and 26, 27 respectively and inclined conduits 28 to 31 which connect the centre region of a preceding cylinder to each end of a succeeding one. Lubricant under pressure entering unit 8 from a supply pipe 9 (see Fig. 2) forces the first piston valve upwards thus connecting the conduit 29 with the pipe 9. This upward movement of the valve closes the port 23 by piston 16b and opens port 22 between pistons 16 and 16a. Due to this action lubricant is also supplied, via conduit 29, to the second valve in cylinder 20, the piston therein being forced upwards whereby lubricant at the upper end of cylinder 20 is expelled via conduit 28 to the outlet 22. In consequence of this piston movement lubricant is allowed to pass to cylinder 21 causing subsequent movement of the piston therein and expulsion of lubricant through outlet 24. This sequence of operation is repeated for any number of distributing valves and when completed a change over valve (not shown) is operated to supply lubricant through the pipe 2 which causes the downward movement of the valves and a reverse sequence of operation, through each of the primary devices. Upon completion of this sequence the lubricant passes from the last primary device, say 8, via outlet 23 and pipe 10 into the inlet 48 of the first secondary device 11. This operates the combined change-over and distributing valve in the cylinder 35 setting off a sequence of operations for discharging lubricant through given outlets to selected points on apparatus to be lubricated, similar to the sequence of operations described for the primary devices. The cycle of operation continues until the supply of lubricant under pressure to the inlet port 48 is interrupted. The number of distributing valves in both primary and secondary units may be varied to suit requirements, only one combined change-over and distributing valve being required for the secondary unit.
