Abstract: 454,732. Two-part couplings combined with switches. SCHMIDINGER, J. F., 2808, 35th Street, Long Island City, New York, and BOHNER, C. C., 74, Kendal Avenue, Maplewood, New Jersey, both in U.S.A. May 21, 1935, No. 14848. Convention date, May 23, 1934. [Class 38 (i)] An annular container 2 containing means for flashing the filament is mounted around the base 4 of an electric incandescent lamp. The flashing means comprises a contact 8 on the armature 10 of a permanent magnet 12, a fixed contact 14 insulated from the base 4 and connected to the filament 16 of the lamp and to a resistance 18, and an expansible wire 20, which may be a continuation of wire 18 and which is secured to a spring strip 22 connected at its other end to the container 2 and to the armature 10 by a screw 24. The contact 14 is connected by a strip 36 to the filament lead 37. The contact 8 may be wedge-shaped so that the distance between the contacts may be adjusted by slight relative rotation of the container and lamp. Alternatively, the contact arrangement shown in Fig. 3 may be employed, in which the lead wire 37 is brought out through the base and formed with a hook 40 to receive the end of the resistance 18, part of the wire 37 being silver plated to contact directly with the silver plated armature 10. The wire 18, 20 is fused in a glass bead 26 in which is also fused an anchor wire 28 ; the tension of the wire 18, 20 is adjusted by the wire 28 which is thereafter welded to the container, the adjustment being such that the contacts 8, 14 are spaced when the resistance 18 is cold, but contact when the resistance is heated by the passage of a current therethrough. A modification of the adjusting means comprises an insulating sleeve mounted on a pin to which a locking wire is spot welded after adjustment; the sleeve is formed with a passage through which the wire 18, 20 passes and a channel to receive the locking wire. Alternatively, the tension adjustment devices may be such that the tension may be adjusted in use.

Title: Improvements in or relating to the bonding of parts of dissimilar metal
IPC: B23P11/00
Filed: 1955-05-25
Abstract: 805,660. Making composite sheets and bearings. BRENNAN, J. B. May 25, 1955, No. 15066/55. Addition to 734,275. Classes 83 (2) and 83 (4). Soldering; welding by pressure.-In bonding two parts of dissimilar metal, the first part is heated over the whole of that face which is to engage the second part whilst cooling the whole of that face which will be directed away from the second part, the second part is heated over the whole of that face which is to be brought into engagement with the first part and then the two heated faces are brought and pressed together while cooling at least one of the parts over that face which is directed away from the other part. In an embodiment the surfaces 3, 4, Fig. 1, of two flanged tubular parts, 1 being of aluminium and 2 being of copper containing 20 per cent lead, are heated e.g. in a vacuum or inert atmosphere by flames 5 or by high-frequency induction, the parts being held in ceramic or metallic fluid cooled parts 6, 7. After heating the surfaces to 400-500‹ F., the softening temperature of the aluminium part, the parts are slid axially under pressure of 500- 1000 pounds per square inch into telescoping engagement and the parts may be rotated or twisted. When the surfaces 4 abut they are rotated relatively or twisted. Nickel, nickel and tin, tin, germanium, indium, silver, lead or iron powder may be applied to the surfaces 3, 4 of the part 2 by spraying or dusting and fusing the powder. Two split bushings which may or may not have their seams welded are similarly joined. Two strips may be slid over one another axially or may be relatively rotated on one another as in Fig. 5 to effect joining. Copper or bronze sintered liners may be joined to aluminium or steel sleeves, the liners being then impregnated with molten lead, e.g. in partial vacuum by dipping the composite body into lead protected by molten salt, e.g. potassium nitrate. The parts may be of tube produced by casting, turning or extruding.
Patent GB-198561-A (GB)
Title: Improvements relating to defibration of cotton seed or cotton seed hulls
IPC: D01B1/04
Filed: 1922-05-30
Abstract: 198,561. Segundo, E. C. de. May 30, 1922. Scouring.-In a process for the removal of the residual fibres retained by cotton seed after ginning, or for the removal of fibres from the decorticated hulls of cotton seed or other fibre-bearing material, the heavily-fibred seeds &c. are segregated from the fibreless or lightly-fibred seeds at any stage of the process, and subjected to a further defibrating operation. The segregator, which is separate and distinct from the defibrating machine, comprises a shallow dish 1 formed with a central compartment 2 and an outer compartment 5 with a sloping floor 3 roughened or coated with abrading-material 6. The dish is suspended from a support 8, and a wobbling movement is imparted by means of a pin 9 mounted eccentrically upon a rotary shaft 13 and working in a bearing 10 at the centre of the dish. An opening 18 with a closing shutter 19 is formed in the floor 3 above a shoot 20 leading to a conveyer 22, an opening 23 with closing-shutter 24 is formed in the. wall 4 of the compartment 2, and an opening 27 is formed above a shoot 28 leading to a conveyer 30. The seeds are fed to the outer compartment, and those with little or no fibre gravitate to the bottom of the mass, and fall through the opening 18; the more heavilyfibred seeds on the other hand tend to collect at the upper level of the mass, and pass through the openings 23 and 27 respectively, and are returned to the defibrating machine.

Title: Improvements in magnetic means for producing, modifying, and transmitting, mechanical movements
IPC: H02K41/00
Filed: 1920-01-21
Abstract: 165,392. Fereday, H. J. Jan. 21, 1920. Variable-speed epicyclic gearing.-Magnetic means is employed to produce the swashing of a plate against a stationary surface, the rotation on its own axis of the plate being conveyed directly by flexible means, such as a universal joint, to the driven shaft etc.; the inclination of the plate may be variable either during running or only when at rest to provide for change of speed of drive, or change of speed or reverse may be obtained by altering the position of the universal joint. The swash-plate A is connected by a universal joint G to the shaft F and bears frictionally or by engagement of teeth a<6>, e, or by combined toothed and friction engagement in which the pitch circles need not coincide, against a stationary pathway E to which are connected twelve electromagnets B. Current is supplied by three leads to the magnets in sets of four, the first lead being excited, then the first and second, then the second, and so on, the plate A being thereby attracted so as to receive a swashing motion, which produces a slow motion of the, shaft F in the same direction as the swashing. The plate A may be further inclined to increase the speed of the shaft F. If the position of the universal joint is changed without altering the inclination of the plate A, so that it approaches and eventually passes beyond the pathway E, the velocity of the shaft F passes through zero to the reverse direction.
Patent GB-420372-A (GB)
Title: Improvements in electric starting systems for internal combustion engines
Filed: 1933-05-27
Abstract: 420,372. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. May 27, 1933, No. 16366. Convention date, May 28, 1932. [Class 38 (iv)] In an electric starting system for internal-combustion engines in which the circuit of the starting motor is controlled by two pairs of contacts 12, 13 ; 14, 15, in parallel, one pair of contacts 14, 15 is retarded both in the opening and closing movement by retarding means 36. A starter switch 4 is controlled by a coil 8 energized on closure of a manual switch 9 and by the two sets of contacts 12, 13 ; 14, 15, the former set being normally open and the latter normally closed. Contacts 12, 13 are closed by the action of a coil 5 carrying motor current and contacts 14, 15 through a resilient lost motion connection 27, 28 by an armature 25 acted on by two coils, one 34 being a generator voltage coil and the other, 31, a motor voltage coil, the movement of the armature being retarded in both directions by a bellows 36 having an adjustable bleeder 39. Closure of switch 9 energizes the coil 8 through contacts 14, 15 and closes the switch 5. This energizes the motor S.M. and coil 5 which closes contacts 12, 13 before contacts 14, 15 are opened by the coil 31 energized by closure of switch 5. Decrease of motor current when the engine starts causes opening of the contacts 12, 13 by the residual E.M.F. of the motor on the coil 31 and the delay action of the bellows 36 maintains the contacts 14, 15 open until the generator voltage builds up sufficiently to hold the contacts open: During slow running of the engine, " rolling " or " kicking " effects thereof on the generator voltage are taken up by the lost motion connection 27, 28 and the bellows 36 and premature or undesirable closure of the starting switch 4 is thereby prevented.

Title: Improvements in method and apparatus for drawing tubes
IPC: B21C1/22
Filed: 1931-05-27
Abstract: 364,494. Drawing tubes. FULTON SYLPHON CO., Knoxville, Tennessee, U.S.A. May 27, 1931, No. 15500. Convention date, June 25, 1930. [Class 83 (iv).] Drawing tongs and mandrels.-The walls of a tube are thinned to size by drawing it through a die while supported internally on a mandrel, and the surface of the tube is burnished by the return stroke of the tube and mandrel through the die, and by part of the forward stroke of the tube through the die while it is being pulled over the mandrel to bring a fresh part of the tube, on the mandrel, so that that part may be drawn and so on. Figs. 1, 1a and 1b pieces end to end give a view of the complete machine. A gripper block 82, having been dropped into the tube 80 to abut against the inturned end, the tube is pushed over the mandrel head 46 of the rod 40 which is tilted upward by the guide 42 moved by fluid pressure cylinder 44. The tube &c. is then lowered, the die 56 is moved to position on it to begin drawing, the drawhead 60 is moved up to operate by levers and gripper jaws 72 to grip the inturned end of the tube between the jaws and the block 82 and the ring nut 75 is screwed up to secure the grip. The pull rod 48 is now screwed into the mandrel 46 and is tensioned by admitting fluid pressure into the cylinder 49. The hand lever 167 is then released. As the crank 27 reciprocates the crosshead with attached racks 34 to the right, the mandrel 46 and the tube thereon is thrust through the die 56 the tube being also pulled through by the stroke of the drawhead 60 when coupled by pawls 67 to the racks 34. The mandrel is also assisted by being pulled by the pull rod 49. When the crosshead starts to return to the left it pulls the drawhead 60 and the tube and mandrel with it, owing to the pawls 70 thereon now being engaged with the racks 33. After about 4/5ths of this stroke which effects a burnishing of the tube in the die 56, the trigger lug 115 releases pawls 70 to stop the tube and engage a pawl 138 with the rack 139 and also allows the clutch 21 to be engaged to rock a toothed sector 141 engaging the rack 139 so that the drawhead 60 is again fed forward to the right. This draws the tube forward to right, further burnishing it while the mandrel 46 is still moving back. When the mandrel 46 and rack bars 34 &c. reciprocate to the right again and overtake the rack 139 the pawls 67 again engage the racks 34 and the drawing through the die 56 takes place on the next portion of the tube as before. When the tube has been completely drawn the handlever 167 is moved to disengage all the pawls so that the drawhead 60 may be slid along and the tune released from the gripper 71 and removed. Specification 298,407, [Class 83 (iv), Metals, Working], is referred to.

Title: Analytical method and free energy measuring apparatus
IPC: G01N25/00
Filed: 1967-04-05
Abstract: 1,132,795. Measuring free energy, osmotic pressure. J. A. PATTERSON. April 5, 1967 [April 5,1966], No.15591/67. Headings G1L and G1S. An apparatus for measuring the free energy or osmotic pressure of a fluid comprises a chamber containing at least one symmetrical particle 38 formed from a fluid swellable, hysteresis-free, cross-linked organic polymer; inlet and outlet means 40, 35 communicating with the chamber for flowing fluid into and out of contact with the particles and means for measuring either the change in volume of the particles at constant pressure or the change in pressure of the particles relative to the internal surface of the chamber at constant particle volume caused by solvating the particles with the fluid. An example given of the particle composition is a cross-linked copolymer of a polyvinyl aryl compound and a monovinyl aryl compound or a divinyl benzene and polystyrene. The apparatus shown in Fig.3 operates at constant volume, pressure changes necessary to keep the volume control being measured by a pressure gauge 48. The apparatus comprises a chamber 31 in which is movable a double-ended piston 32 sealed against the chamber walls by rings 33, 34. A plurality of beads 38 are positioned in the lower end of the chamber between retention screens 41, 42. Test fluid enters at inlet 40 passes through the beads and thence out through right angle channel 35. A read out arm 43 is connected at right angles to the piston so as to convey the movement of the piston to a read out component 45. In operation pressure is applied to the top of piston 32 from pressure source 46 while a standard fluid is introduced at the inlet, the pressure at this time being taken as a standard. The test fluid is then fed in at the inlet; if the osmolarity of the test liquid is less than the standard liquid, the beads will expand moving piston 32 upwardly. By applying additional pressure to the top of the piston 32 it can be moved back until the movement is nullified. The increase in pressure required is directly proportional to the difference in osmolarity a free energy of the standard liquid and the test liquid. In other examples described the constant pressure change in volume method is used the expansion or contraction of the beads operating an arm to a read out device in a manner similar to the arm 43.
