Abstract: 1,249,560. Heavy-current switches; contact members for switches. SIEMENS A.G. 29 Aug., 1969 [30 Aug., 1968], No. 43230/69. Heading H1N. A rotary switch, operable by a handwheel 42 or by a motor, comprises a frame 5 rotatably supporting contact blades 2 on a spindle 3 for engagement with laminated contact members 12 providing flexible connections to busbars 11 via terminal portions 13, the frame 5 being fixedly supported independently of the busbars, and includes a loading device 25, which creates contact pressure in the closed circuit position, the device 25 being coupled via a friction coupling with the drive means for the contact blades 2. The loading device 25 comprises two thrust plates 26 on spindle 3 in the form of nuts having opposite threads, and the blades 2 are connected together and to the thrust plates 26 by clamping bolts 30. Two discs 32 on spindle 3 act as stops for the plates 26, the discs 32 being supported by spring washers 33 against nuts 34 on the spindle. Between the discs 32 and plates 26 are friction discs 35 permitting relative rotation. Upon opening of the switch, plates 26 move apart along the threaded portions 36 of the spindle 3 to release the contact pressure between blades 2 and contact portions 14 of contact members 12. Upon hitting the stops 32, the plates 26 follow the rotation of spindle 3, carrying the blades 2 with them until the opencircuit position is reached. This position is determined by a plate 37 secured to the blades 2 and plates 26 by bolts 30 and co-operating with slots (not shown) on the frame 5. Closing of the switch reverses the procedure, until plates 26 apply clamping pressure in the closed-circuit position. With a motor drive, limit switches 40 are operated in each end position, Fig. 2 (not shown). Adjustable comb-like distance pieces 16 are provided between the contact members 12.

Abstract: 1,194,838. Refrigerating. ELECTRIC & MUSICAL INDUSTRIES Ltd. 28 Sept., 1967 [28 Sept., 1966], No. 43468/66. Heading F4H. Cooling apparatus comprises a tube through which a liquefied gas passes to an expansion orifice, part of the tube being cooled by the expanded gas from the orifice and part being arranged in contact with a device to be cooled, the latter part of the tube being isolated from the expanded gas. As shown, liquefied gas 4 is maintained under pressure in a reservoir 1 by a relatively volatile liquid 3 on the remote side of a free piston 2 and is supplied through tube 5 to a helical coil 6 in an enclosure 7. A length of tubing 8, 12 arranged outside the enclosure connects coil 6 to a further coil 13 and a further length of tubing 14, 18 connects coil 13 to another coil 19. The latter is connected to an expansion orifice 25 by tubing 20, 24. Each length of tubing outside the enclosure includes a coil 9, 15, 21 wound around an infra-red detector 11, 17, 23. Thus, coils 6, 13 and 19 are cooled by gas from the orifice 25 while detectors 11, 17, 23 are cooled by the liquid in their associated coils in the absence of such gas. This is stated to reduce the noise level in the detectors. Enclosure 7 includes a further orifice supplied with liquefied gas through line 29 from reservoir 28.

A ball joint, see Fig. 1, is fitted with a bush 13 of hard, low friction, plastics material, the bush being interposed between the joint pin 2 and an inner side face of a collar 9 and rotatable with the joint pin. At one end, the bush faces the joint housing 1 and it is formed at the other end with a supporting flange 14 against which the end face of a collar lip 16 bears. The lip may be undercut and a clamping ring 10 may be located in the undercut area. To prevent the collar sliding towards the housing a portion of the joint pin is surrounded by a distance sleeve 11. In another embodiment (Fig. 2, not shown), a more efficient seal is achieved by means of annular ribs (18) formed around the outer surface of the bush, snugly engaging in complimentary grooves formed in the inner side surface of the collar. In a further embodiment (Fig. 3, not shown) the bush is formed in one piece with the distance sleeve. In a further embodiment (Fig. 4, not shown) a rib (20) formed on the joint pin is arranged to abut against the inner end faces of the bush and collar to prevent the collar sliding towards the joint housing.

A seed or fertilizer metering device comprises a body 22 and a rotary metering member 15 having a fluted portion 45 and a tubular extension 46 non-rotatably mounted on a drive shaft 19, and a cylindrical cut-off element 48 freely rotatably mounted on the extension 46, the shaft 19 being axially movable by means of a handle 71 so as to bring the metering member 15 into an in-use or an out-of-use position, from which latter position the member may be withdrawn from the body in a direction transverse to the said axis. The device is mounted beneath an aperture 18 in a storage hopper. The fluted portion 45 rotating with the shaft 19 meters quantities of material to a seed boot 43 hung on the hooks 41. A locking ring 51 prevents the extension 46 and the cut-off element 48 from moving axially with respect to the shaft 19. A sealing disc 56 axially movable relative to the shaft 19 and fluted portion 45 is rotatably journalled in an aperture 26 in the body 22, a U shaped spring 60 holding the disc in position. When the member 15 is to be moved to the out-ofuse position the lever 71 is operated to move the shaft 19 from right to left (as seen in Figs. 2 and 4). The locking ring 51 and hence the cut-off-element 48 are thus moved to the left, the latter replacing the part of or the whole of the fluted portion 45 which is in the chamber 69. The member 15 may be removed from the body by detaching the spring 60 from the bearing surfaces 65 and extracting the member 15 so that the cylindrical portion 48 passes through the open slot 28 and the shaft 19 through the slot 29. A cut off flap 68 is provided having a cross member 95 supported between the depending side walls 94, A spring control plate 98 is mounted on a shaft 20 and has a spring locator 101 and an abutment face 104 which engages the surface 103 on the flap 68. The flap is adjusted by rotating the shaft 20 and is able, because of the spring 100, to adjust itself in response to the amount or size of material being discharged by the fluted member 45. In an embodiment, Fig. 5 (not shown), a replacement fluted portion having smaller flutes is described.
