In the embodiment shown in Fig. 2, the thickness of the roof coal band 13 is sensed during the floor cutting stage by a nucleonic sensing and detecting probe 20 to control the cutting horizon 16. Other parameters may be sensed, in addition to that of the roof coal band thickness, to steer the mining machine, these include the position of the machine along the working face, the position of the mine roof 12 with respect to the top of the machine, the position of the cutter drum 2' during the floor cutting stage with respect to the conveyor, the inclination of the machine in a direction normal to the conveyor, and the position of the cutter drum 2' with respect to the machine. The sensed parameters are fed to a control means 40, e.g. an analogue or digital computor. A restriction of the adjustment of the position of the cutter head relative to the conveyor is imposed to avoid large steps in the floor 9. The cutter drum winning the upper coal may lead the machine so that the probe can sense the cutting horizon associated with the roof cutting stage during both directions of traverse of the machine. The steering method may also be applied to a double end ranging drum shearer.

Abstract: 1370329 Casting processes PRECISION METALSMITHS Inc 7 Dec 1971 [9 Dec 1970 28 May 1971] 56757/71 Heading B3F  A method of casting metal in a gas-permeable mould 120 comprises applying a vacuum to the opening 122 of the mould, introducing molten metal under vacuum into the mould through said opening, increasing the pressure on the metal in the mould, and applying a vacuum to the outside of the mould prior to solidification of the metal. The increased pressure applied to the metal in the mould may be provided by releasing the vacuum applied to the opening of the mould. The mould 120 is located in a housing 18 secured to a framework 15. A second housing 19 provided with wheels 47 is movable along rails 40 between a position above the housing 18 and the broken line position shown in Fig. 1. The rails 40 are pivoted at one end to the framework 15 and at their other end are connected to a piston and cylinder unit 44 which is used to raise and lower the rails. When the rails are in their lowered position the housing 19 engages the housing 18 to form a sealed enclosure having a pouring chamber 65 and a mould chamber 66, the two chambers being isolated from one another. The mould is contained within a perforated flask 128 and is located on a metal plate 72 provided with a gasket 73. A refractory core is positioned within a mould passage 123. The pouring chamber 65 is provided with a laddle 95 which may be tilted by an external handle 102 and filled through an opening 103 in the housing 19. In operation, the mould is placed in the housing 18, the housing 19 moved into engagement with the latter, both chambers 65 and 66 are evacuated, the metal is poured from the ladle 95 into the mould, and the vacuum is released in the chamber 65 whilst maintaining the vacuum in the chamber 66 during at least partial solidification of the metal.

Title: Snapaction electric switches
IPC: H01H21/44
Filed: 1971-12-07
Abstract: 1384552 Snap-action switches; variable resistors CTS CORP 7 Dec 1971 [7 Dec. 1970] 56851/71 Headings H1N and HIS A snap-action switch comprises a stationary contact 41, a resilient member 44 having integral therewith both a movable contact 54 and a first terminal 53 of the switch, a movable cam 55 mounted for rotational movement in an interference path with the resilient member 44 to produce movement of contact 54 into and out of engagement with contact 41, the resilience of member 44 providing the snap action and the contact-making pressure, and a stationary, surface 52 to control movements of member 44 and impart additional loading thereto to enhance the snap action, the contact 54 being movable towards and away from contact 41 and also along the surface thereof with a wiping action. As shown the arrangement is combined with a variable resistor and is operated by a shaft 18 which rotates a disc 19 carrying wipers 20 having contact fingers (21, Fig. 4, not shown) wiping an arcuate resistance element 12 connected to terminals 13, and studs (22) wiping a slip ring 14 connected to a terminal 15. The cam 55 is formed on the reverse of disc 19 which also has a projection 34 co-operating with a portion 33 (bent in from cover 31) to limit rotation to less than one complete revolution, and to locate the OFF position as shown in Fig. 6. The cam 55 acts on a lateral extension of the end of member 44 to urge its contact surface to follow an X-shaped path (Fig. 10, not shown). Thus, clockwise rotation of cam 55 from the Fig. 6 position lifts the contact 54 (in conjunction with surface 52) until its corner 50 snaps over the cam corner 56 and the contact 54 snaps into engagement with contact 41, as in Fig. 5. Reverse rotation of cam 55 now lifts contact 54 to slide up contact 41 until corner 50 snaps over corner 56 and the OFF position of Fig. 6 is restored Thus contact 54 makes and breaks at different points on contact 41, and, owing to the curvature of surface 54, the points of making and breaking are also somewhat spaced on contact 54 itself.

A rotary-piston I.C. engine, particularly but not exclusively of the trochoidal type, comprising as shown, a peripheral casing wall 1 having a bi-arcuate epitrochoidal inner profile 2 and a three-sided piston which on planetary rotation controls peripheral admission and exhaust passages 9, 11, includes a pipe 19 connecting the compression space 17 with the suction space 16 of the engine at a point 20 between the admission and exhaust passages so that part of the compressed air or air-fuel mixture is forced into the suction space to blanket the admission passage from the exhaust passage to prevent or at least reduce the flow of exhaust gases into the suction chamber. A closable flap 23 at the inlet 21 to the pipe 19 is linked to a throttle valve 22 in the admission passage 9 so that when the throttle valve is closed during idling and at low load the closable flap 23 is fully open to ensure regular running of the engine and when the throttle valve is opened to increase power the flap 23 moves towards closure and remains closed from a predetermined engine-speed range upwards when the flow of exhaust gases into the suction space is of less importance. The inlet 21 is located at a position so that it is passed over by a piston corner as soon as the exhaust passage 11 has been passed over by the next piston corner so that the flow through the pipe 19 does not last longer than the overlap between the admission and exhaust passages.
