Abstract: 1330865 Testing impedance to earth RANSBURG CORP 17 Sept 1970 [17 Sept 1969] 44435/70 Heading G1U [Also in Divisions G4 and H3] In an arrangement for checking whether an object 15 which should be earthed, is earthed by a sufficiently low impedance path, (and therefore checking the propensity of the object for becoming electrostatically charged) a potential is applied to the object by a probe 14 and if sufficient current flows (indicating an adequate earth) a trigger 21, 22 fires to energize a relay 25 which holds over its contact 61 and prevents, by opening its normally closed contact 60, the energization of a lamp and bell which would otherwise normally occur following detection of the presence of the object 15 at the testing position by a micro- or photo-electricswitch 10 closing a contact 16 and thereby energizing a relay 35 which, via its contact 62, controls the lamp and bell. If the current that flows following the application of a potential to the object 15 is too low to fire the trigger 21 and 22, the normally closed contact 60 is not opened, and hence when the contact 16 closes, indicating the presence of the object 15, the lamp and bell are energized. A further relay 27 is provided which, by its contact 64 and a capacitor 29 is arranged to cause a transistor 31 to conduct momentarily following the opening of contact 16 when the object is removed from the testing position, in order to release relay 25 (which, if it has been energized, will be holding over its contact 61). The relay 35 may, if desired, be provided with a hold contact 63 and a normally closed release contact 36. The system described is for use in an electrostatically coating plant in which metal objects 15 are suspended by earthed hooks for conveyance through a coating unit, and in which, because the hooks may become dirty or covered with the coating being applied, a suspended object 15 may be inadequately earthed thereby presenting a hazard since such an object may become electrostatically charged and cause an explosion.

Title: Overrunning brakes
IPC: B60T7/20
Filed: 1971-11-23
Abstract: 1364540 Over-running brakes for trailers KOBER-MANPAR AG 23 Nov 1971 [27 Nov 1970] 45342/73 Divided out of 1364539 Heading F2E An over-running brake for trailer wheels comprises an internal shoe drum brake with two shoes including an expanding device so mounted between two adjacent shoe ends that in one direction of hub rotation the primary and secondary shoes act respectively as leading and trailing shoes and in the reverse direction their functions are reversed, an adjusting device mounted between the other ends of the shoes, and resiliently compressible bracing means supporting a bolt which is mounted in a guide slot formed in the secondary shoe and extending at an acute angle to the tangent at the radiallyadjacent friction surface of the secondary shoe, the bracing means bearing against the secondary shoe at a position closer to the expanding device than the guide slot. As shown, the upper shoe 2, Figs. 1 and 3, is anchored at 10, while the lower shoe 3 is adjustably anchored at 32, 34 (see below) to a slackadjusting device. The shoes are actuated by two levers 16, 16<SP>1</SP> and 17, Fig. 2, pivoted together at 18 and operated by a Bowden cable 56. A stop 57, Fig. 1, limits the movement of lever 16, 16<SP>1</SP>. When the trailer is moving forward (arrow 4, Fig. 1), 2 is the leading shoe and 3 is the trailing shoe. For forward and over-running braking, anchoring of shoe 3 is effectively by contact of a bolt 21, located in a slot 20 in the web of shoe 3, with the bottom end of part 32 of the slackadjusting device. Trailer reversing.-When the trailer is reversed by the tractor vehicle, the Bowden cable 56 is automatically pulled, tending to apply the brakes. But the wheel is now rotating in direction 5, Fig. 1, so shoe 3 is the leading shoe. Initial friction contact between the drum and shoe 3 moves shoe 3 counter-clockwise, whereupon the shoe, by means of part 24 of a stay structure 22 forming part of the bracing means, compresses two springs 25 and is thereby enabled to move transversely of bolt 21 by slot 20, the end of the shoe web meanwhile riding up into a gap 34, Fig. 3, provided in the end of part 32. Slot 20 is so orientated in relation to the tangent to the drum at that point that the abovedescribed movement of the shoe carries it away from the drum. Since also, in these circumstances, shoe 2 is the trailing shoe, and since the shoes are floating, the brake is hardly applied at all. Part 23 of stay 22 is in two parallel sections joined by the bolt 21. Slack-adjusting.-The device consists of the parts 10, 32, Fig. 3, with adjacent wedge-shaped ends, mounted in a tube 29 through which extends transversely a threaded member 31 whose wedge end 30 engages the parts 10, 32. The end of member 31 is located outside the back plate and provided with an adjusting nut.
