Single-type composing and casting machines; matrices.-Matrices are formed on the side opposite to the formative cavity with a stop-surface adapted to co-operate with mechanism for deter. mining the set-width of the mould; a number of such matrices may be mounted in groups on an endless chain which can be traversed horizontally and shifted verticallv to bring the selected matrix into register with the mould, and each group of matrices may be associated with a stop-member for determining the body width of the mould. Matrices 10, Fig. 4, are formed on the sides opposite to the formative cavities 76 with stopsurfaces or cavities 77 of depths corresponding to the set-widths of the formative cavities. The mould is arranged so that one or, in some cases both, of the side walls 72, 73 can be adjusted set-ways by means of a bar 83 having a wedge surface 82 engaging a bar 81 operated by a lever 80 arranged between spring-plungers 78, 86. When a matrix is in register with the mould, the plunger 86 is operated by an eccentric 85 and the plunger 78 enters the cavity 77 and determines the adjustment of the mould. The plunger 78 serves also as an aligning-means for the matrix. The matrices may be mounted in carriers 9, Fig. 1, connected to form a chain passing over sprockets 13; preferably there are seven matrices in each carrier, and a group of fifteen carriers is provided for each style of type employed. A pinion 40 drives the shaft 39 of one of the sprockets by means of a slipping clutch 44, driving in the opposite direction, by means of pinions 48, a disc which can be connected by means of an electromagnetic clutch 43 to the shaft 49 of another of the sprockets. By controlling the clutch 43 and the rotation of the pinion 40, the chain can be traversed in one direction or the other to bring a group of carriers into position and to bring a carrier into register with the mould.

Title: Improvements in or relating to automatically variable change speed gear devices
IPC: F16H61/02
Filed: 1936-12-14
Abstract: 472,016. Variable speed gearing. BERLIN, D. W. Dec. 14, 1936, No. 34312. [Classes 80 (ii) and 80 (iii)] Relates to automatically-variable changespeed gear devices of the kind with centrifugal weights drawn round over eccentrics which transmit alternating impulses through oneway friction ratchets or grips, and particularly to means comprising a centrifugal governor to prevent wear in these ratchets when idling on high-speed direct drive. In Fig. 1 is shown the application to the gear device described in Specification 422,368 in which 1 is the sleeve which carries the eccentrics to which the alternating impulses are imparted. The forward impulses are transmitted directly to a driven shaft 2 through one-way grip rollers 8 ; the rearward impulses are transmitted as forward impulses through one-way grip rollers 9, through a reversing train 4, 5, 6, and through one-way grip rollers 10. The idlers 5 are non-planetary being upon fixed supports, and the high-speed direct drive takes place through the jammed rollers 8 with both sets of rollers 9, 10 overrunning. A centrifugal governor 14 carried by the driven shaft 2 eases the engaging springs 22, Fig. 10, not only of the overrunning rollers 9, 10, but also of the jammed rollers 8. The expanding weights 14, Fig. 1, act against a spring 17 and through a U-shaped fork 13 and ring groove 13b to thrust a muff 12a leftwardly. The muff 12a has ring groove connections with radial pins 12b which are constrained to turn with the shaft 2 by straight grooves 12c therein. The pins 12b pass through inclined slots 12d, Fig. 5, in a double-ended roller housing 11, and this axial shift of the muff causes an angular shift of the housing 11 relatively to the shaft 2 which releases the spring pressure on both sets of central rollers 8, 10. The outer set of rollers 9 are likewise released by the angular displacement of their housing 12 by pins 12f engaging inclined slots 12g in the housing and carried by a drum 12h having a straight-groove connection 12i with annular grip flange 3 of the gear 4. There is described with reference to Figs. 2 and 6 (not shown), an application to the gear device described in Specification 413,039 in which the idle toothed gears corresponding to the gears 5 of Fig. 1, are supported in a revoluble abutment member which turns solidly forwards during direct drive.

Abstract: 902,035. Knitting. COTTON Ltd., WILLIAM. Oct. 24, 1958 [Nov. 5, 1957], No. 34405/57. Class 74 (2). In a straight-bar machine having two sets of simultaneously-operated needles and means for changing between rib and non-rib work during knitting, the machine needles 2 have associated with them yarn control elements 7 which not only, by means of abutments such as 7A, position new yarn under the beards of the needles 2, to space it clearly from the old loops RLF on those needles, but which also penetrate and spread the last drawn machine needle loops, for these loops to be pierced by empty frame needles 1A, in changing back to non-rib work. The elements 7 may have points 7c slightly offset from, and their abutments 7a set over to, their centre lines and have each a clearance for the associated frame needle head. In the elements of Figs. 17 and 18, abutments are formed by cranked parts which also provide for loop spreading, either without shogging, or with shogging, when a coacting groove 26 is provided in the machine needle to receive the point of the element. Figs. 19 and 20 show forms of yarn control element operating respectively from above and from below the machine needles. Fig. 21 shows yet another form of element. The needles 1A have associated therewith points 5 which not only close the beards of the needles 1A during rib knitting, so that kinks of the newly-fed yarn Y are landed on to those beards and thence on to noses 3A of pairs of sinkers 3, to be taken therefrom by the machine needles 2, but which also, immediately before the change from non-rib to rib work, form a picot course by transferring the last-drawn loops from these needles 1A to the other frame needles 1B. Specification 841,471 is referred to.

Title: Method of forming a thermometer
IPC: G01K5/04
Filed: 1972-08-22
Abstract: 1412761 Moulding thermometers THERMEX Inc 22 Aug 1972 34490/72 Heading B5A [Also in Division G1] A thermometer comprising in combination a capillary element and a reservoir bulb, is calibrated by completely filling the bore and reservoir with an indicator liquid maintained at an elevated temperature, cooling the indicator liquid to a preselected lower temperature, determining the location of the top of the liquid column in the capillary bore at this lower temperature, and placing a scale on the capillary element with an indicium thereof corresponding to the lower temperature positioned accurately in alignment with the determined top of the liquid column. As described for moulding and then calibrating the thermometer, a carbon rocket wire 22 (Fig. 2) plated with brass is strained between a support 24 and retainer member 28 through an injection mould 18, 19. Polystyrene or polypropylene is injected around the wire to form a capillary tube, the mould halves 18, 19 are opened (Fig. 5) and the capillary tube 11a pushed out of the mould by support 24. The retainer member 28 is lowered and the support 24 returned to the left to pull the wire 22 back into the mould for moulding of a further capillary tube, while the already moulded tube 11a is held by posts 30, 29. As the mould halves 18, 19 close, a camming surface 51 rotates the post 30 (see Fig. 2) to urge the tube 11a to the right to retension the wire 22. Two capillary tubes can be moulded simultaneously (see Fig. 1, not shown).  A moulded plastics bulb 12 (Fig. 11) having an embedded, cold rolled steel sleeve 16, is then sonic welded to the capillary bore. After completely filling the bore with indicator liquid 15 heated to 112‹ F., a projection 31 (Fig. 9) on the end of the capillary tube 11a is bent over to seal the tube, by a heated former 32; (alternatively the bore is left open ended). The indicator liquid is cooled to 98‹ F., and the level in the capillary bore sensed with a radiation source (41) and photo-electric cell (40) (Fig. 13, not shown) which actuate an impression die (38) for applying a scale to the capillary tube.
