Filed: 1937-02-26
Abstract: 484,943. Rolling sheets. TRIGGS, W. W. (American Rolling Mill Co.) Feb. 26, 1937, No. 5793. [Class 83 (iv)] Rough plates A with initial transverse convexity are sheared from the product of a continuous hot mill 1, so as to have less width (54in.) than the desired width (66in.) of finished sheet D, are turned round and so cross rolled at 2 (preferably in a matched pair) from B to C where the original convexity is preserved and are again cross rolled without turning round in rolls 3 (e.g. 5 to 7 passes) to produce a finished flat sheet D. The mill 2 may therefore be of short rolls and the mill 3 of long rolls. The rolling to finished size is carried out with the heat retained in the sheet as it comes from the rough mill 1. The degree of convexity may be affected by cooling the centre part of the rough sheet by water, or by flexing the rolls.

Title: Shaft head or shaft bottom operating equipment with an electro-hydraulic master control unit for controlling the working devices provided at the shaft head or bottom
IPC: B66B17/20
Filed: 1962-02-16
Abstract: 993,436. Automatically loading wire cages. G. DUSTERLOH FABRIK FUR BERGWERKSBEDARF G.m.b.H. Feb. 16, 1962 [March 11, 1961], No. 5993/62. Heading B8E. An electro-hydraulic control unit, Fig. 3, automatically operates the necessary working devices at a shaft head or bottom when either mine cars or men are to be loaded and raised or lowered, after an electromagnetic valve 13 has been moved to one or other of its two operative positions, which correspond to either " cars " or " men." In addition a further electromagnetic switch 14, operated by a banking cage, ensures that the working devices pertaining to the appropriate one of two cages which operate in the shaft are selected. For winding cars gates 4, Fig. 1, platforms 5, catches 6, 8 and a ram 7 are all operated. When men are to be wound only gates 4 and platforms 5 are required to be operated. To wind cars a banksman moves the valve 13 to the left in Fig. 3 to admit liquid from a pump 11 to the right hand end 28 of a valve 15. This moves a piston 30 to the left against a spring 31 and connects conduits 22a, 23a, 24a, 25a with conduits 22- 25. When a cage banks the valve 14 is moved to either right or left, depending on which cage banks, to admit pressure liquid to either the right or left hand end of a valve 16 thereby moving a piston 36 to either the left or right. This movement connects conduits 22-25 with either conduits 22b-25b or 22c-25c, these two latter groups of conduits leading to the working devices at the shaft head associated with the two cages. As soon as the piston 36 reaches either end of the cylinder communication is established between either conduits 37, 34 or conduits 38, 35 so that as soon as valves 18-21 are opened by a hand lever 17 carrying operating cams liquid flows either through conduits 33, 34, 37 or 33, 35, 38, through one of the oneway valves 39 and conduits 22a, 22, 22b, 25a, 25, 25b to the working devices. When the devices have operated the cam-shaft 17 turns back, the conduits 22-25 are connected to unloading pipes 40, 41 and all the devices and valves return to their inoperative positions. If men are used the valve 13 is moved to the right in Fig. 3 and liquid passes into a chamber 29 of the valve 15 through a conduit 27, this moves the piston 30 to the right and the construction is such that only conduits 24, 25 are connected to conduits 23a, 24a. This ensures that only the gates 4 and the platforms 5 are operated. The rest of the control is effected as previously described. Individual working devices may be operated by manually opening any of valves 18-21 with valve 13 in the " car winding " position.

Title: Safety control device for mine hoists and the like
IPC: B66B5/08
Filed: 1924-03-10
Abstract: 235,288. Logan, H. H. March 10, 1924. Dash-pots.-In safety-control apparatus for mine hoists of the kind in which a member connected to braking means is released upon excessive speed and at the ends of the wind and the movement of the member is controlled by a dash-pot that is cutout on an overwind, the movement of the dash-pot mechanism is controlled by one passage during the main run and is freed near the ends of the wind by the opening of a normallyclosed by-pas passage by cam mechanism geared to the hoist. As illustrated, a weighted arm, which applies the brake, is connected to the piston of a dash-pot 5, which in addition to a small orifice 24 in the piston has ports 7, 8 leading through hollow trunnions to a valve. During the main run a rotating member 17 of the valve prevents direct communication between the passages 11, 12 leading to the ports, leaving the orifice 24 as the sole means of communication between the upper and lower sides of the piston. In the event of an overwind, one of two cams geared to the hoist, operates a lever to rotate the valve member 17. This establishes direct communication betwen the passages 11, 12 to a greater or less extent, depending on the amount of overwind, and correspondingly frees the piston for rapid descent. When the weighted arm is raised by hand for re-setting, a by-pass 20 furnished with a one-way ball valve 21 operates to permit ready pasage of the fluid from the upper to the lower side of the piston. Specification 152,466, [Class 78 (v), Winding and paying-out apparatus &c.], is referred to.
