Title: Means for interconnecting male and female members
IPC: F16B2/16
Filed: 1973-11-27
Abstract: 1491446 Spigot-and-socket joints MATTHIAS SPENCER & SONS Ltd 27 Nov 1974 [27 Nov 1973 (2) 55058/73 and 55059/73 Heading F2M [Also in Divisions E1-E2] A coupling member, e.g. a pick box 10, is adapted to receive a shank or spigot on another member, e.g. a mine pick 13, by providing it with a socket of a cross-section, e.g. square, corresponding to that of the shank or spigot, and arranging a ball or roller in such a way that it is biased to project into the socket so that its curvate surface engages the shank or spigot frictionally, whereby, on inserting the shank or spigot, the ball or roller rolls against the bias out of the path of the shank or spigot, whilst being operative to wedge the shank or spigot against reverse motion, externally accessible release means being provided for shifting the ball or roller against the bias to a position out of rolling engagement with the shank or spigot to permit removal of the latter. In Fig. 1, a roller 15 rolls within an inclined passage in pick box 10, the passage opening at one side into the socket interior. A rubber pad 16 urges the pin upwardly as shown so that it engages spigot 12, formed on the pick 13, with a frictional force sufficient to ensure that attempted withdrawal of the spigot causes the pin to roll and increase its gripping force on the spigot. The ends of the pin project beyond the sides of the pick box 10 so that the pin can be manually depressed, compressing the pad 16, to allow withdrawal of the spigot. In the embodiment of Fig. 4, the retaining element is a spherical ball urged upwardly by a rubber pad 18 within a bore inclined upwardly towards the interior of the socket, the ball being retractable by axial sliding of a pin 19 having a waisted portion normally allowing the ball to engage the spigot. The waisted pin 19 may be replaced by one having a recess for receiving the ball in its operative position and which is rotated to cause retraction of the ball (Fig. 7, not shown). In the embodiment of Fig. 9 a part-spherical end 29 of a lever 30 resiliently mounted by a rubber block 31 in a wall of the pick box is normally urged by the block 31 upwardly in an inclined bore so that it can engage the spigot and roll as in previous embodiments, the lever being moved manually to retract the end 29 when required. The end 29 may be barrel shaped or have flats on its periphery. In the embodiment of Fig. 12 an eccentrically mounted pin has a body recessed to accommodate a rubber pad 51 which urges it to rotate such as to exert a camming action on the spigot 42. A hexagonal end of the pin is engaged by a key for releasing the spigot.

Title: Improvements relating to welding power sources
Inventor: NEEDHAM JAMES CHRISTOPHER
IPC: B23K9/10
Filed: 1967-12-20
Abstract: 1,210,099. 099. Arc welding control circuits. NATIONAL RESEARCH DEVELOPMENT CORP. Dec. 19, 1968 [Dec. 20, 1967], No. 57921/67. Heading G3R. An arc welding power supply includes a magnetic amplifier controlled in response to the arc voltage, the time constant of the rate of change of the control current being less than one tenth of a second. In the embodiment described, the magnetic amplifier includes a control winding 16 which is shown with its control unit in Fig. 2. The amplifier is energized by an A. C. supply of frequency between 200 and 2000 c/s. A reference voltage, which may be modulated, e.g. for pulsed arc welding, is derived from a potentiometer R7 and is compared with the instantaneous arc voltage by a transistor T1. The conductivity of the transistor T1 is thus determined by the arc voltage, and the current in the control winding 16 is limited by a resistor R1 if the transistor is conducting, and by a resistor R2 if the transistor is blocked. A switch 53 may be closed to provide positive feedback from the arc. A network including transistors T2, T3 operates to bias the transistor T1 into full conduction when welded is first begun, the bias being removed when the arc has been struck.
