IPC: B67D7/16
Filed: 1921-11-25
Abstract: 192,536. Poore, C. T. Nov. 25, 1921. Addition to 29087/13. Fixed-chamber apparatus; valve systems for; varying quantity measured in; with counting and registering aparatus.-The apparatus described in the parent Specification is mounted by (1) arranging the weir and gauge bar to counterbalance each other and to move in opposite directions, (2) improved means for effecting the pump and discharge interlock, and (3) improved means co-operating with this interlock and locking the gauge bar which moves rectilinearly. A vessel a contains a weir b with depending overflow tube c connected to a pipe e associated with the bucket chember f. The weir is connected to the gauge bar g by a chain h. The pump 3 delivers through a pipe k passing to the top of an encircling stand pipe m communicating by means of an elbow n with the bottom of the vessel a. Siphoning is prevented by providing a pierced cap o. The gauge bar is provided with a handle s and a slide plate p guided along the rods t. This bar may be locked by a bolt u shot into one of a series of recesses in the slide p. Each recess is formed in a fitting which may be adjusted along a slot in the plate p and then clamped. The discharge valve 2 and pump 3 are interlocked by means of a bolt 4 an arm 5 on which is adapted to engage a notched plate 6 or the valve spindle while an arm 8 is connected through link 9 and lever 10 to the pump locking member 11. A third bolt 12 carries a rack 13 for operating gear 14 connected to a counter and may be permitted to move differentially by the introduction into its path of any one of a series of stops 16 of different lendgths on the gauge bar. All the bolts are operated in proper sequence by a rotary spindle 18 which can turn in one direction only, having three cams 21, 22, 23. Assuming all bolts retracted then on turning the spindle the cam 21 shoots the bolt u and holds the gauging bar and weir in adjusted position. The next cam 22 engages a pin 23<x> on a head 24 sliding freely on the bolt 12 against a spring 28 and moves the bolt which itself slides against a spring 25. The third cam 23, when the valve 2 is closed, shoots the bolt 4 and frees the pump. The retraction of the bolt 4 may be effected by a quadrant lever 32, 33 connected to the overflow bucket. On opening the valve 2 a pin 35 engages and causes idle movement of a weighted lever 36, while on closing the valve, the pin rocks the lever 36, the part 38 engaging the pin 39 and retracting the bolt a.

Title: Method and Apparatus for Curing Elongated Articles
Inventor: FOLKES HUGH LORAIN
IPC: B29C35/02
Filed: 1965-11-10
Abstract: 1,175,521. Curing presses; laminating. DUNLOP CO. Ltd. 3 Nov., 1966 [10 Nov., 1965; 14 July, 1966], Nos. 47594/65 and 31657/66. Headings B5A and B5N. An elongated article such as rubber or plastics belting, chipboard or plywood is cured by passing it stepwise through a press comprising a plurality of pressing units, each of which consists of upper and lower heated platens. The units are successively clamped on to the article at a first station, move with the article to a second station whence they are removed, and are finally transported back to the first station for re-use. In the embodiment shown in Fig. 3, two belts 4 and 5 are cured simultaneously by continuously steam-heated units 1A-1G and 2A-2G which move in a closed path from belt to belt. The units are hydraulically clamped at stations S3 or S1 on to the belts and move forward therewith in the direction of the arrows, the belts themselves being intermittently forwarded by clamps 6-9 and 10-13. As each unit arrives at stations S4 or S2 it is unclamped from its associated belt and transferred across suitable runways and turntables (not shown) to stations S1 or S3 whence it is re-engaged with the other belt. During the curing period the edges of the belt are constrained by irons inserted between the platens by stations 20 and 21. In a second embodiment (see Figs. 8, 9, 11 and 13, not shown) for use with two belts, the platens are heated only at the beginning of the pressing and curing operation by passing the units, located about the belt, between the heated plates of a stationary press. The units are clamped together by screws whilst still in the press, subsequently removed from the press by forward movement of the belt and are removed from the associated belt and transferred to the other belt as in the above embodiment. In a third embodiment (see Fig. 15) for use with a single belt, the belt is looped to pass between the upper and lower tiers of a stationary double daylight press 108, and the pressing units are not contiguously disposed during the curing but are spaced apart to give alternating cured and uncured areas after the first pass through the press. In operation, the pressing units are pre-heated, applied to the upper run of the belt at S1, and then passed with the belt, through the press to station S2. The units are then unclamped and transferred to station S3, via a second pre-heating unit, applied to the lower run of the belt at the areas not previously cured, and moved with the belt back through the press to station S4. The units are finally removed from the belt and transferred, via a pre-heating unit back to station S1 for reapplication to the belt.

Abstract: 693,590. Fuel-injection Pumps. C.A.V., Ltd. Dec. 3, 1951 [Dec. 30, 1950], No. 31681/50. Class 7 (iii). A spring-loaded stop f setting the normal maximum supply position of a fuel injection pump control rod a is movable transversely of the rod a by a manually operated plunger j to permit the end i of the rod a to enter an aperture h in the stop to provide an increased fuel supply for starting, the plunger j being disengaged from the stop f by the motion of the rod a to its starting position. A bevelled collar k on the plunger j co-operates with the chamfered entrance n of the aperture a to cause depression of the stop f when the plunger j is moved to the left. A projection o holds the rod a in a reduced supply position, Fig. 2, while the rod j is depressed to prevent the excess fuel supply being obtained at times other than starting. When the plunger j is released the rod a is moved to the right by the governor loading spring, and the entry of the part i into the aperture h moves the plunger j back to its inoperative position so that the stop f returns to its normal position after starting when disengaged by the rod a.

Abstract: 918,036. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 15, 1960 [Sept. 17, 1959], No. 31884/60. Addition to 888,196. Class 40 (4). In a selection control arrangement, for marking an idle one of a number of circuits, consisting of a number of stages each associated with one of the circuits, each stage has a marking output at which marking potential appears only when " free " potential is applied to its testing input and " release " potential to its coupling input, and a coupling output at which " blocking " potential appears when marking potential appears at the marking output, or when " blocking " potential is applied to the coupling input, the arrangement being such that the blocking potential appears at the coupling output without time lag, the connection between the coupling input and coupling output of each stage is established by a transistor and the stage at which an attempt at selection is to be commenced is determined by connecting a further potential to an auxiliary input of that stage which input is connected to the coupling output of the respective stage. Each of the stages A, B ... N may be in accordance with any of the stages disclosed in the parent Specification which has a transistor connected between its coupling input k1 and its coupling output k2. The auxiliary input n is connected to k2 over rectifier G1 and to the base of the transistor over G2, and the stages are connected in a closed ring. A device Sp connects positive potential corresponding to the release or idle potential to input n of one stage and a negative potential corresponding to the blocking potential to the others. In the one stage the positive potential appears at k2, and hence at k1 of the succeeding stage, which is thus the first choice stage. This potential also disables the transistor of the one stage.
