Title: Improvements in or relating to roof supports for underground mines
IPC: E21D15/48
Filed: 1952-07-17
Abstract: 748,868. Chocks for mines. MUSCHAMP, N. J., and COWLISHAW, F. July 17, 1953 [July 17, 1952], No. 18056/52. Class 20(2). A mine roof support comprises a pair of uprights 1 connected by a bridge 2 formed with inclined bearing plates 3, a chock 4 slidable on each bearing plate 3, and a shoe 7 which overlies each chock 4 and bears thereupon through the intermediary of a transverse wedge 18 by which the shoe is adjusted vertically, each shoe 7 being connected to the bridge 2 by a pivot bolt 8 which passes through vertical slots in the side plates of the bridge 2 to allow bodily vertical movements of the shoe 7 and bolt 8. The roof is supported through the intermediary of bars or beams 25 resting on the shoes 7. The support is collapsed by operating a lever 26 which releases the chocks 4 so that they slide down the inclined bearing plate 3, allowing the shoes 7 to swing downwardly on their pivots, Fig. 2, in such a manner that the bars or beams 25 are freed and are consequently ejected from between the support device and the roof. The support may also be square in plan having four uprights 1 and two bridges 2, there being a chock and shoe at each corner. Specifications 684,403 and 720,537 are referrred to.
Patent GB-180993-A (GB)
Abstract: 180,993. Krupp Akt.-Ges., F. June 3, 1921, [Convention date]. Cash registers with several item-value totalizers.-In a key-set independently-operated machine, depression of a key in one bank, for example a clerk's key, initiates a setting-movement which is completed by the depression of a key in another bank, say the cash key in the transaction bank, so that in the subsequent operation of the machine and in addition to the usual differential actuations, the totalizer of the particular clerk concerned is thrown into operative position. The clerks' keys F are individually locked except when a detachable key H<4> is present in its rotatable barrel H connected with the stem of the key F by an arm f<1> engaging a helical slot in the barrel. Pivoted on a spring- controlled plunger M<1> arranged in an extension M of each barrel casing is a lever M<3> pinned at one end to the arm f<1> and having its other end M<4> extending into the path of movement of the flange n<1> of a slide. N. The stem of the cash key B has a cross-pin b<1> bearing on this flange so that when a clerk's key F has been depressed, and the lever end M<4> consequently brought against the flange n<1> the depression of the cash key carries along the slide N and also, through the lever M<6>, the plunger M<1> which is thereby thrust forward as a stop to limit the differential displacement of a disc P serving to throw into operation the particular clerk's totalizer. In the case of transactions other than cash, the transaction key ACR, Fig. 8, when depressed advances a stop t<1> to cause through the disc P the corresponding special transaction totalizer to be put into active position. Any of the transaction keys serves to start the machine by shifting a slide Q, and the ends of the key stems also act as stops for the differential displacement of a disc S connected with the transaction indicator and printing-mechanism. The clerks' keys perform a similar function in conjunction with a disc K. Specifications 173,219 and 177,506 are referred to.

Filed: 1937-06-30
Abstract: 495,213. Manual exchange systems. ERICSSON TELEPHONES, Ltd., and GREEN, B. A. June 30, 1937, No. 18168. [Class 40 (iv)] The calling indicator of a party line is controlled by a capacitative timing circuit so that it operates only in response to a continuous calling signal and not to the intermittent calling signal employed in calls between parties on the line. The timing circuit may be common to a number of incoming lines. Line relay LA responds to alternating calling current as shown or to direct current and connects up relay P. Relay A operates and connects up relay B which locks and disconnects A. A high capacity condenser QA which charges before B pulls up now discharges through A and holds this relay for a definite period. If LA is still up when A falls back, a circuit is completed for the indicator IN, but if LA falls back first, the relapse of P immediately restores the timing circuit to its original condition.

Abstract: 546,288. Aircraft arrester gear. BLACKBURN AIRCRAFT, Ltd., THARRATT, R., and THIRSK, W. H. Dec. 30,1940, No. 18223. [Class 4 An arrester gear for aircraft comprises a telescopic arm pivoted rearwardly of the tail wheel so as to be capable of swinging from a stowed position against the fuselage to an operative position as well as laterally, the arm having a hook at its free end to engage wires stretched across the land deck. An arm 10 of hollow rectangular section is pivoted about a vertical pivot 3 fixed in a block pivoted about a transverse pivot 1 in a block 2 fixed beneath the fuselage. Sliding within the arm 10 is a cylindrical member 11 having a square head 30 fitting the interior of the arm 10 so as to prevent rotation of a hook 12 at the rear end of the member 11. Lateral swinging of the arm 10 is limited by rubber-faced stops 6 and resisted by a spring pressed roller 8 engaging an edge cam 9 fixed to the pivot 3. The member 11 is urged outwardly by a spring 36 until the head 30 encounters a buffer 4, but in the stowed position a pin 15 on the hook 12 is engaged by a forked member 13, Fig. 3, fixed to the fuselage, this fork carrying a catch lever 14 which also engages the pin 15. To release the arm, the lever 14 is moved by a cable 16, on arm 18 on the lever ensuring the disengagement of the pin 15 from the forked member 13. The pin 3 is connected to the piston rod of an oil damper 19 which allows the arm 10 to fall freely but resists return movement. The damper is supplied with oil from a reservoir 20 and the flow is controlled by a relief valve 21 as described in Specification 525,016. The arm 10 is enclosed by a streamline casing 37.

Title: Improvements in or relating to billiard tables
IPC: A63D15/00
Filed: 1935-06-27
Abstract: 458,787. Billiard tables. MOULE, H. A., 222, Jeffcock Road, Wolverhampton. June 27, 1935, No. 18389. [Class 132 (ii)] [See also Group XVIII] In a coin-freed billiard table game, pocketed balls are at first returned to the player by way of a series of traps leading to an open receptacle, the first ball pocketed passing through the first trap and closing it, the second ball passing over the first trap and through the second, and so on, until all the traps are closed, pocketed balls then passing over all the traps to be delivered to another receptacle from which they are recoverable only after insertion of a coin. Alternatively, only a ball or balls of a certain size (e.g. the larger cue ball employed in the game of pyramids) are at first returnable by way of the traps, the other balls (e.g. smaller object balls) being always non-returnable. The construction shown is of this form. Pocketed balls are led to spaced inclined rails 14 between which the smaller object balls drop to an incline 40 which conveys them to a coin-freed drawer 24. The larger cue ball, however, runs along the rails 14 to an incline 16 having a series of apertures 17 with hinged cover flaps 18 which are at first all in raised position. The first time the cue ball is pocketed, it passes through the first aperture 17, and is led by a lower shoot 20 and a curved guide 21 to an open receptacle 23 always accessible to the player. In passing through this aperture 17, the ball engages an abutment 19 on the flap 18 which is turned over to close the aperture, so that the next time the ball is pocketed, it passes through the second aperture for return to the open receptacle 23, and so on. When the cue ball has been pocketed as many times as there are apertures, the next time it is pocketed, it passes over all the now closed apertures, and falls to the coin-freed drawer 24. The flaps 18 are raised again for further play as the drawer 24 is opened to obtain the balls, by means of transverse pins 39 carried by a pair of slides 38 connected by a lever 36 with the drawer. The invention is applicable to the apparatus described in Specification 425,237.

[Class 20(iv)] Wall or ceiling boards are attached to supporting structures by first securing to the surface of each board, each at a small distance from one of the two opposite edges, two reinforcing members having outwardly projecting flanges. the boards being supported by suspension units fixed to the structure and passing between adjacent boards to interlock with separate, readily releasable, locking means disposed on the outer face side of the boards the suspension units supporting the boards through the reinforcing members and engaging the flanges thereof to prevent their lateral displacement. In the form shown, reinforcing members 2, consisting of metal angle sections, are attached to the upper faces of boards 1 near the edges thereof. The boards are attached to the structure to be lined by supporting means positioned at each end of the members 2, the means comprising a suspension unit 3, a supporting unit 4 and two locking members 5 which serve to lock units 3 and 4 together. The unit 3 has a slot 6 through which passes a strap 7 attached to the structure. Before erection the end corners of each board are cut away to accommodate the supporting unit 4 which engages under the members 2. The unit 3 is then placed against the unit 4 with its lateral arms 8 engaging over the upstanding flanges of the members 2. The locking members 5 and 6 are then slid towards each other in the coincident slots 9 and 12 and the arms 17 bent up, as shown in Fig. 1, to lock the assembly together. The entire weight of the boards is thus supported by the reinforcing members 2 which bear on the members 4, and the lining can be readily detached from the supporting structure without damage to the boards.
