Title: Method of and apparatus for rendering solder coated on a metallic surface level and thin
IPC: H05K3/34
Filed: 1968-07-01
Abstract: 1,216,577. Soldering. BROWN ENG. CO. Inc. 1 July, 1968 [6 July, 1987], No. 31396/68. Heading B3R. To produce a level and thin coating of solder on a metallic surface coated with solder, the surface is moved across a tank containing liquid at a temperature above the melting point of the solder and the liquid is discharged as a spray on to the surface in a direction opposite to the direction of movement of the surface. A rectangular tank 11 having walls insulated by panels 13 is carried on a frame 12 and contains oil or molten potassium nitrate F heated by an immersion heater 48. Two channels 16 extend across the top of the tank to form a track for printed circuit boards which are conveyed from left to right in the figure by a driven chain 25 having board engaging elements 26. A pump 30 submerged in the oil &c. F has its intake 31 near the tank bottom and discharges through a pipe 32 into two horizontal parallel pipes 35, 36, one above the channels 16 and the other below. A number of spray nozzles 37 are provided on the pipes which are inclined towards the left in the figure. A solder trap 44 is supported in the tank below the channels 16 with a screen 45 overlying the trap and the space above the trap enclosed by a cover 46. An outer upper cover 47 encloses the top of the tank. In operation printed circuit boards coated with solder by wave soldering or electrodeposition are fed along the channels 16 to the right in the figure and sprayed oil &c. from the tank impinges against the upper and lower surfaces of the board to melt the solder and spread it evenly, excess solder falling into the trap 44. When using eutectic 63% tin, 37% lead solder the oil &c. should be 40-60‹ F. above the melting point (380‹ F.) of the solder, e.g. 430‹ F.

Title: Method and apparatus for arranging bricks into proper row size for stacking and packaging
IPC: B65G47/32
Filed: 1975-07-29
Abstract: 1506444 Arranging bricks for stacking, and packaging FORREST PASCHAL MACHINERY CO 29 July 1975 [29 July 1974] 31596/75 Heading B8C Apparatus, for altering the row sizes of brick courses removed from a kiln car K in preparation for stacking and strapping, comprises a table 10 having a receiving end 11 and a discharge end 13; means 12 for accumulating and moving courses of bricks S toward the discharge end 13, the courses comprising a plurality of rows and columns with a known number of bricks therein, a carriage 16 slidably attached to the end 13 for reciprocation longitudinally thereof between a retracted position beneath the discharge end and an extended position beyond the discharge end; and a pushoff means 18 for moving the bricks collected on said carriage transversely thereof. Each stack S includes a plurality of double-layer courses of bricks with successive courses in orthogonal relationship, alternate courses being rotated 90 degrees so that each course is deposited upon the marshalling end 11 of the table with the rows of headers extending longitudinally of the table. Two courses S are unloaded from a kiln car K whereupon the push mechanism 12 is actuated to move the courses against an upstanding carriage wall 17. The continuous pressure exerted by the push mechanism 12, commences to move the carriage 16 outwardly against the air, or fluid, pressure of a cylinder (76). When a prescribed number of bricks per row have been moved on to the carriage 16, the latter engages a limit switch (80) so that the clamp 14 is lowered to engage the remainder of the bricks, the push mechanism is deactivated, and the cylinder (76) is energized to move the carriage 16 gently to its fully extended position. The push mechanism 18 is then actuated to transfer the bricks collected on the carriage on to a conveyer 20 which transports the bricks to a stacking, and strapping apparatus. If, at this time, the number of bricks on the table is less than the said prescribed number, the push member 12 will have been retracted to push another group of courses down the table 10. Two tables (10<SP>1</SP>), with their discharge ends directed towards each other, and a common carriage 16<SP>1</SP>, Fig. 5, not shown, permit the unloading of two kiln cars at once from opposite ends of the tables. The pusher 12 and the table 16 carry pairs of rollers 38, 74, respectively, which move along tracks formed by the bottom flanges of a pair of side frame members 50, the pusher 15 also being guided by a rack-andpinion mechanism 60, 42. The pusher 12 is operated by a piston-and-cylinder unit (30, 32) which could be replaced by a rotary drive means, not shown, which drives the pinion 42, Fig. 4. Other regroupings may be formed by using the apparatus.

Title: Improvements relating to control means for electrically operated welding machines
IPC: B23K11/31
Filed: 1935-11-15
Abstract: 465,806. Electromagnetic switches. BUCKLEY, SAUNDERS, & CO. (PONTELEC), Ltd., and BUCKLEY, P. Nov. 15, 1935, No. 31641. [Class 38 (v)] [Also in Group XXXV] Switching control.-For the purpose of timing a weld, the actuation of the ordinary control means simultaneously brings into operation movable means which tend to break the welding circuit but is controlled by an adjustable dashpot. When the electrodes are closed on to the job by the pedal, contact 4 closes a circuit through the operating member in the contactor casing A, thus supplying current from mains T<1>, T<2> to the primary winding 20 of the welding transformer, and simultaneously energizing solenoid 5 which then moves its armature 6a upwards under the control of dashpot piston 7. After an interval, depending upon the setting of the dashpot byepass valve 11, disc 12 on the armature 6a engages lever 13 and opens contacts 15, 16, thus breaking the welding circuit and de-energizing the solenoid 5. The armature 6a and dashpot piston then move downwards in readiness for the next weld, a one-way valve in the piston allowing such movement freely. The lever 13 and contacts 15, 16 may be adjusted vertically to give a time adjustment in addition to that given by the valve 11. The contacts 15, 16 may be replaced by wipe contacts.

Filed: 1926-12-14
Abstract: 281,873. Griffiths, T. L. Dec. 14, 1926. Making burners; wick burners, solid - flame. - A wick burner nozzle is formed by first slitting transversely one end of a tubular metal blank b at c and flanging or flaring its other end d, as shown in Fig. 4, then expanding the slit end to oval formation, thereby forming,horns f as shown in Fig. 7, and finally clipping away the material between the horns f to the required state of nozzle required, as shown in Fig. 10. The blanks may be subsequently cleaned, tinned, or galvanized. Alternatively, two nozzles may be formed from a single blank by first flaring the blank at the ends, then subjecting the middle of the blank to a denting operation to give it an oval crosssection, and finally piercing the blank at the middle in the direction of the minor axis by a tool which shapes the end of each section to the required form. In some cases the blanks may be formed with an integral wick tube or closed at the base to receive the wick tube.

Title: Lock-up clutch controls
IPC: F16D47/06
Filed: 1972-07-06
Abstract: 1336705 Change speed control GENERAL MOTORS CORP 6 July 1972 [5 Aug 1971] 31707/72 Heading F2D In a motor-vehicle in which a gas-turbine 28 drives through a fluid-pressure engaged friction clutch 32, which as shown, is a lock-up clutch of a fluid coupling 30, and a transmission 26 providing four speed ranges DR1 ... DR4, under control of a manual selector valve 18, the clutch 32 is controlled through a shift valve 22, which is biased left, to'exhaust the clutch engage line 98 at 102, by a spring 104 and by pressure (modulated as described below) in a disengage bias line 108, and is biased right, for pressurizing the clutch with line pressure 16, by speed responsive pressure 100 from an output driven governor 24; by modulated pressure in an engage bias line 110; and, after rightward movement, by line pressure 16, acting on a differential area of the valve to provide hysteresis. The disengage and engage bias lines 108, 110 are alternately pressurized and exhausted by a control valve 54 which is biased left by a spring 122 and right by line pressure 16 fed to a line 46 in DR1 setting of the manual selector valve 18, the pressure 68 thereby supplied to the bias lines 108, 110 being modulated by a valve 20 loaded negatively by engine compressor pressure 56, whereby modulated pressure 68 is inversely proportional to engine torque. Action is as follows: (a) DR1 setting. DR1 pressure 46 moves the control valve 54 right to supply modulator pressure 68 to the engaging bias line 110, which assists governor pressure 100 in shifting the shift valve 22 right to engage the lock-up clutch 32. If the modulator pressure is sufficiently high, i.e. at low engine throttle opening, lock up will occur even at zero speed. With the vehicle in motion governor pressure acts with modulator pressure to produce lock-up, and above a predetermined speed the combined pressure will produce lock up even up to minimum modulator pressure (i.e. at full throttle torque); (b) any setting other than DR1. The DR1 line 46 is exhausted permitting the control valve 54 to move left to supply disengage bias pressure 108 to the shift valve 22. Due to differential lands b, c on the shift valve, this bias pressure 108 assumes a fixed value above a predetermined modulator pressure 68 and is equal to modulator pressure below that value, so that governor pressure 100, acting on the shift valve 22, causes lock up at progressively increasing speeds with decrease in engine torque (increase in modulator pressure), up to the said predetermined modulator pressure value, above which lock up is speed responsive only. The transmission 26 may be that described in Specification 1,310,070.

Abstract: 893,111. Centrifugal pumps. EDWARDS, M. L. Oct. 6, 1958, No. 31844/58. Class 110 (1). [Also in Group XXVIII] A submersible fuel pump P, Figs. 3 and 4, is inserted by means of a tool T into an aircraft fuel tank C through an access hole in the top wall of the tank. With the discharge conduit 12 of the pump in engagement with a discharge fitting F carried by the tank, the pump is rotated by means of the tool T to bring hook-like lugs 12f on the conduit 12 into the position shown in Fig. 3 in which they engage screws 40 on the discharge fitting F. Splined nuts 41 are then tightened by means of a socket wrench. Gas and vapour in the liquid entering the pump impeller 28 are expelled back to the tank through passages 24 and directed by a lip 25 away from the pump inlet. The pumped liquid passes through diffuser vanes 31 and then through an annular passage 13 to cool the motor M before entering the discharge conduit 12. In a modification, the discharge fitting F is attached to the bottom wall of the tank and is turned upwardly at an angle to receive the correspondingly downwardly-angled pump discharge conduit 12. In a further embodiment the discharge fitting F is integral with the top cap of the pump. The pump, with the top cap and fitting F bolted to it, is inserted into the tank through a hole in a side wall of the tank and the fitting F is then bolted to the tank around the hole. The pump can be unbolted from the top cap and dropped down from it for replacement without removing the top cap and fitting F from the tank. The pump shown in Fig. 10 is connected to the discharge fitting F by means of a pipe 174 and an elbow 188 and is supported partly by the fitting F and partly by the engagement of a spigot 178 with a supportmember 180. If the pump fails it is by-passed by a check-valve 177. In a modification, the discharge fitting F is attached to the top wall of the tank with the pump depending from it through a vertical pipe. The base of the pump engages a support-ring attached to the bottom wall of the tank.
