Abstract: 836,035. Making heat-exchangers; stamping. REYNOLDS METALS CO. Sept. 26, 1956 [Dec. 1, 1955], No. 29437/56. Classes 83 (2) and 83(4). A method of expanding a pressure-welded passageway panel for a heat-exchanger comprises expanding the panel between dies in pressure engagement with opposite sides of the panel, at least one of the said dies being arranged to yield under the panel expanding pressure during the panel expanding operation whilst maintaining pressure engagement with the panel from a point approximating zero expansion to a point of desired expansion. A panel 1 is clamped between a spring-loaded upper die 7 and an hydraulically-operated lower die 5, the clamping pressure being between 200 to 1000 p.s.i. The expansion apparatus 9 is operated to force hydraulic fluid into the passageways 3 to expand them against the spring-loading of the upper die. An expansion pressure of between 3000 to 4000 p.s.i. is required. During the expansion the metal 12 between the crest 11 and the body of the panel is worked and strengthened and the hitherto tendency to neck down avoided. The springs of the upper die are designed to exert a clamping force equal to the expansion force when the panel is fully expanded. Alternatively, gauge blocks 14 determine the guide position of the dies. In a modification the upper die is stationary.

Patent GB-394542-A (GB)
Title: Improvements in or relating to lubricating systems for reciprocating piston and cylinder machines
IPC: F16N13/18
Filed: 1932-10-21
Abstract: 394,542. Lubricating. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN and KYLEN, K. E., 17, Artillerigatan, Gothenburg, Sweden. Oct. 21,1932, No. 29502. [Classes 12 (i), 12 (ii), and 12 (iii).] In a reciprocating piston and cylinder machine, lubricant is constrained to pass through an antifriction bearing on the crank pin 65 to an antifriction bearing on the gudgeon pin 51 and thence to the cylinder walls. Lubricant entering the crank-case at 87, Fig. 1, passes through a main roller bearing 63 to a lubricating ring 70 on the crank web and via a passage 69 to a hole 76 in the crank pin. The crank pin bearing assembly comprises rollers set 73, separated by a loose spacing and oil-distributing ring 79, inner and outer race rings 72, 71 and sealing rings 75. The rings 72, 71 are each provided with radial holes and an annular groove enabling oil to pass to a port 82 below an inertia-operated pump comprising a pump cylinder 100 mounted in the connecting rod, a piston 83 and inlet and outlet ball valves 103, 84. The end movements of the piston 83 are cushioned by oil trapped below the valve 84 and above ports 102, 102a. Oil discharged by the pump passes through a groove 86 and a passage 89 to a roller bearing 47 surrounding the gudgeon pin 51. Oil escapes at the ends of this bearing into a channel 48 formed partly between a spring-pressed packing device 52 and the gudgeon pin and passes thence to the cylinder walls via channels 58, 59. The other main bearing 62 is lubricated by grease which is prevented from escaping by a shield 64. Air escapes back into the crank case by holes 60. In a modification, the roller bearings of the gudgeon pin are mounted in the piston 50 and the passage 89 communicates by a radial passage with the interior of the gudgeon pin by the open ends of which oil reaches the cylinder walls. Radial oil passages lead from the interior of the gudgeon pin to the roller bearings, excess oil also passing out of the bearing ends to the cylinder walls. Four other forms of the sealing devices 75 are shown and described. In two of them, the inner race ring is omitted and the rings are integral with or abut the outer race and extend to the gudgeon pin. In another form, the sealing rings are integral with the inner race ring and extend to the inside of the outer race ring. In the fourth form also, they extend to the outer race but are separate from the inner race. In this last form, additional spring-pressed sealing-rings are located between the connecting-rod and the crank webs, Fig. 5 shows an alternative form of pump having a piston 38 with a throughbore 36 in which the delivery valve 37 is positioned. The pump chamber 39 is separate from the connecting rod and the piston 38 has projecting nozzles 41, 42 by which the air-oil mixture is cushioned in annular chambers 44, 43. A cross bore 45 permits oil to escape from the chamber 44. In this form the inlet valve 27 is spring-loaded.

Abstract: 504,630. Electron multipliers. FARNSWORTH TELEVISION, Inc. Oct. 29, 1937, No. 29591. Convention date, Nov. 9, 1936. [Class 39 (i)] In an electron multiplier wherein an electron cloud is caused to oscillate to impact the secondary emitting surfaces a number of times, longitudinal drift of the cloud is effected by setting up a potential gradient along an electrode centrally arranged within the emitting surfaces. Electrons from a cathode 6, Fig. 1, pass a control grid 7 and enter a secondaryemitting cathode 29 through an aperture 30. To the collector 19 is connected a high resistance wire 20 forming a central electrode and oscillations relative to this wire are applied to the cathode 29 from an oscillator 31 whereby the electrons. are caused to make repeated impacts with the interior of the cathode 29; the potential gradient is formed along the wire 20. A focusing coil 33 is provided. In a modification, Fig. 3, electrons are oscillated between two high resistance secondary emitting cathodes 47, 49, between which a herring-bone grid, with high resistance supports and leads 55, 56 is arranged ; the potential gradient is formed along this grid with its supports. The bias for the cathodes 47, 49 is obtained by connections to the grid. The collector 62 is placed beyond the cross-grid 59 formed at the end of the main grid.

Title: A new or improved indicating device for use on centrifugal machines to facilitate obtaining balance thereof
IPC: C25D5/06
Filed: 1932-10-24
Abstract: 406,797. Testing balance of rotary apparatus. STROUD, B., 1, Eastgate, Bourne, Lincolnshire. Oct. 24, 1932, No. 29688. [Class 106 (ii).] A device associated with the drum or basket of a centrifugal machine, indicates, when the load is unbalanced, that part of the drum or basket where an increase in the load is necessary to produce balance. A circular cup 1 with a transparent top 6 is attached to the machine shaft by the boss 2 and screw 3, and a few small holes 7 form passages which assist in keeping the top 6 clear. The cup contains a hollow metal body 8 of octagonal section containing a steel ball 9, and carrying on its top a pivoted pointer 10 with a weighted tail 12. The lower face of the body 8 has a central external protuberance 10, and also has a number of countersunk holes 14 in which the ball 9 can rest. If the drum is unbalanced during working and the shaft sways, the body 8 moves to a position on the wall of the cup dependent upon the loading of the drum, and the position of the pointer has a definite relation to the point where more weight is required in the drum. During rotation of the machine, the ball 9 moves to one side of the body 8 and is seated in one of the holes 14 thereby maintaining the body 8 in the indicating position while the machine is stopping. In the modification shown in Fig. 5, the octagonal body 8 is replaced by a solid rectangular block 16 with its sides shaped to form appropriate pointers 17. The block may be faced with leather to facilitate easy movement. In the further modification shown in Fig. 6, the indicator body is of hollow form having a rectangular frame 18 with an annular base 19 and contains a ball 20. The top has an indicator mark 21. In a modification suitable for use with an overdriven machine, an annular frame surrounds and rotates with the spindle. An annular recess in the frame carries the indicating body or block.
