Title: Electric sockets
IPC: H01R13/453
Filed: 1974-10-12
Abstract: 1484911 Electrical sockets MIDLAND ELECTRIC MFG CO Ltd 9 Oct 1975 [12 Oct 1974] 44288/74 Heading H2E  A socket comprises a housing having a front panel with spaced first and second holes for current carrying pins of a plug, and a third, earth, hole that is slightly offset from a line joining the axes of the first and second holes, there being further provided a shutter member that is movable substantially parallel to said line only by substantially simultaneous insertion of pins in the first and second holes. The shutter member is biased to a closed position where access to current carrying contacts via the first and second holes is prevented, the earth connection being accessible in both the closed and open positions. In a first embodiment, Figs. 1 and 2, shutter member 24 pivots about spring-loaded plungers 26, 27 if an object is inserted through only one hole 15, 16 a projection 32 or projections 34 which engage in corresponding recesses 33, 35 preventing lateral sliding of the member 24 to its open position. Upon simultaneous insertion of pins in the first and second holes 15, 16 and initial displacement of member 24 the projections 32 and 34 are clear of recesses 33, 35, the pins then sliding the member 24 via ramp portions 30, 31 against the bias of spring 40. In a further embodiment, Fig. 5, simultaneous insertion of pins 135 into holes 102, 103 causes abutment of the pins 135 with cam surfaces 124, 125 so as to clear projections 117, 118 from recesses 111 against a bias from arcuate resilent arms 126, 127. The pins then engage corresponding ramp portions 122, 123 so as to move the shutter member 112 against the bias of spring 133 to its open position, a pin 130 travelling in an L-shaped slot 131 to limit movement of member 112. In both embodiments a central aperture in the shutter member allows access to the earth contact at all times.

Title: Stamping apparatus for bottle closure caps
IPC: B67B3/04
Filed: 1962-12-04
Abstract: 961,799. Making caps; capping. HOLSTEIN & KAPPERT MASCHINENFABRIK PHOENIX G.m.b.H. Dec. 4, 1962 [Jan. 20, 1962], No. 45755/62. Headings B3A and B3Q. A stamping device for use on mild bottle capping-machines which produces aluminium caps in two different sizes comprises two stamping machines disposed adjacently in one housing into which a drive shaft having an eccentrically disposed coupling projects, the shaft being adapted to be coupled optionally with either of the stamping tools by a connecting ram. Two tools having split rams 6 connected by an adjustable link 7 are mounted in a housing 1 and driven via a shaft 3 having an eccentric end 4 on which is attached a looselyfitting coupling 5 which is optionally connected to one of the rams 6. The lower ends of the rams are pivotally connected at 8 to the diecarriers. An aluminium band is fed to the left-hand unit from an upper draw-off roll 10 and a guide roll 13, over a tensioning roll 12 on a bell-crank 11 moved by means of an eccentric (not shown) contacting a roll 15, over a guide roll 14, lower guide rolls 12, 13, and past the dies to a discharge mechanism comprising a pair of rolls 16, 17, one of which is driven. The right-hand unit is similarly fed from a lower draw-off roll after disengaging the upper guide and tensioning rolls 13, 12 and engaging the lower guide and tensioning rolls 13, 12 in conjunction with the lower draw-off roll 10. In operation, the respective tensioning rolls 12 are moved by the eccentric against the strip to prevent the drawn-off strip from moving through the dies during the stamping operation. The speed of rolls 16, 17 is adjusted to the greatest band feed so that slipping occurs with lower feeds dependent upon the tension applied to the strip by the tensioning rolls.

In use, the support arms 13, 13A and the shaped member 15 are rotated about the axis of the pivot bar using a lever 12, Fig. 2, and optionally a foot stirrup (33), Fig. 1 (not shown) so that the curved bar 34 catches the animal behind its rear legs; at the same time the curved bar 18 catches behind the animal's front legs and forces the animal backwards onto the shaped member 15 which acts as a cradle supporting the animal on its back. By adjustment of the effective length of the arms 19 and/or the position of the pivot point 41, Fig. 3, between the arms 17 and the arms 13, 13A, the orientation of the shaped member 15 corresponding to the closed position of the curved bar 18 can be varied. The bar 18 may be removable so that the animal may be lifted off the shaped member 15 by means of a conveyor. The curved bar 34 is movable relative to the shaped member 15 and may be drawn against the animal's rear legs by means of a chain 38, Fig. 3, attached to a bracket 39 on the frame. The posts 25 are mounted on a rotatable bar 26 and can be raised and lowered by means of a lever (29), Fig. 1 (not shown). The apparatus may alternatively be hydraulically powered.
