Title: Improvements in or relating to conveyor systems
IPC: B61B10/02

Abstract: 816,848. Overhead conveyers. KING, D. M. Dec. 13, 1957 [Dec. 27, 1956], No. 39319/56. Class 104 (2). In a conveyer system in which loadcarrying trolleys 20 are propelled along a fixed track by pusher dogs 19 carried by an endless chain 10, the dogs 19 are supported on the endless chain 10 so as to be capable of lateral displacement from an operative position in which they engage the loadcarrying trolleys 20 to an inoperative position in which they are clear of the trolleys 20. In the arrangement shown the dogs 19 are pivotal, in the direction of travel of the endless chain 10, about a pin 18 carried by a member 16 in turn pivotal, in the transverse direction of travel of the chain 10, about a pivot 17 mounted in a clevis 15 which supports the chain 10 on rollers 12 carried by a track 13. The dogs 19 are normally guided by angles 21 but at holding stations A, B along the track the dogs 19 are pushed transverse to the direction of travel of the chain by pivoted bars 22, 26 out of the trolley-engaging position (shown in full lines) to the inoperative position (shown in dotted lines). The pivoted bars 22, 26 can be manually or electrically pivoted from an inoperative position in which the dogs 19 engage the trolleys 20 to an operative position shown in Fig. 3 in which the dogs 19 are laterally pivoted out of engagement with the trolleys 20, thus allowing the continuous forward movement of the endless chain 10 but retaining the trolleys 20 in the holding station. When the trolley 20 is to be moved from the holding station A the bar 22 is moved to the inoperative position so as to enable a dog 19 to engage and propel the trolley 20. The limit of the pivotal movement of the dogs 19 is determined by a safety-bar 25 which may be fixed to the guides 21 or coupled to the bar 22. The bar 26 is generally similar to the bar 22 but is provided with a forwardly-extending portion 28 bent to form a cam-like part 30 which normally lies in the path of a trolley 20 at the forward station A so that the trolley 20 engages the cam 30 to tilt the bar 26 to the operative position in order to pivot the pusher dogs 19 out of engagement with the trolleys 20 occupying the preceding station B.

[Also in Division H1] A plate 14, through which electrical conductors 13 pass and which may be bolted over an opening 17 in the wall of a tank, e.g. the tank of a distribution transformer, has recesses 22 provided around bolt holes 15 in the plate so that when it is bolted over the opening the nuts 21 lie below the level of its surface. The plate is preferably moulded from a plastics material, e.g. an epoxy resin, with the strip-like conductors sealed in bosses 12. Electrical connections to the conductors 13 are made using the boltholes provided at each end of the conductors, the resilience of the plate permitting the connections to the terminals of the transformer winding to be rigid. A gasket 18 ensures that the plate seals the opening against leakage of fluid once nuts 21 have been tightened. A cable box 26 may subsequently be bolted over the plate without unscrewing these nuts.

Title: Improvements in fabric width gauge

IPC: G01B7/04
Filed: 1957-12-23
Abstract: 868,062. Measuring width of sheet materials. FIRESTONE TIRE & RUBBER CO. Ltd. Dec. 23, 1957, No. 39916/57. Class 40 (1). The relative positions of the two edges of continuously - moving sheetmaterial are detected by feelers contacting the edges and inducing voltages representing deviation of the edges, the voltages being added algebraically to give a measure of the instantaneous width of the material and balanced against a third voltage which is adjustable to bring the resultant of the voltages to zero. In Fig. 3 a roller 17 follows the edge of the material 7 and the drag due to movement of the material which tends to rotate the arm 15 about the pivot 16 is compensated by a spring 22. As the position of the edge fluctuates, the arm 13 pivots about the axis 40 against a spiral spring 46, and rotate the wheel 48 to which is attached the transformer core 68 via the cable 52. The lower end of the core is joined to another cable 69 which passes over a pulley 70 and is anchored by a spring (Fig. 4, not shown). A similar device senses the other edge of the material and the two transformer cores 68, 78 (see Fig. 5) thus move in accordance with the positions of the edges. The primaries of the transformers are fed with A.C. in series with each other and with the rebalancing transformer 90, and the secondary outputs are added together to energize the servomotor 92. This moves the core 93 until the rebalancing voltage fed to the amplifier 91 is sufficient to cancel the input to the servomotor. The latter operates a pointer 94 to record width variations on a moving chart, and can also drive a controller to adjust the width as necessary. Reference has been directed by the Comptroller to Specification 710,177.
