Consists in a machine, specially for filling metal-link belts of the kind described in Specifications 5898/15 and 11753/15, comprising a reciprocating plunger operated from a rotary handle; a feed movement for the belt in which a lever, actuated during the return stroke of the plunger, engages the previously inserted cartridge; means for preventing backward motion of the belt; and a feed-hopper into which the cartridges are correctly placed bv hand, or, alternatively, are thrown in indiscriminately, the cartridges, in the latter case, being correctly arranged by gravity in passing from the hopper to the position in front of the plunger. In the construction illustrated, a table a carries a. hopper b<1> and feed-shoot b, a belt-guide c, a reciprocating plunger d, and mechanism for operating the plunger comprising a rotary handle f and a disk f<3>, both on a sheet f<1>, a pin f<4> on the disk engaging a slot in the lever f<6> which is connected by a link f<7> to the plunger. The lower part of the feedshoot b is open at each end and is provided with spring tongues at the sides to grip each cartridge as it arrives at the delivery end of the shoot. The belt e to be filled has pairs of clips c<1>, c<2> into which the cartridges are pushed by the plunger, and knuckles e<3> connecting consecutive links coact with a spring tongue g, which is fixed by a braclcet g<1> above the guide c so that its forward end g<2> engages successively behind the knuckles. The belt is fed forward intermittently by a lever h pivoted at h<1> and having the forward end h<2> arranged over the belt in position to engage the last cartridge inserted in the belt at a point between the clips e<1>, e<2>. The rear end of the lever h is fitted with a yielding cam i pivoted at i<2> and engaging a stop i<1> on the plunger, as in Fig. 5, so that the cam yields during the forward stroke of the plunger, but reciprocates the lever h during its return stroke. A modified form of hopper j<1>, Fig. 8, and shoot j may be used to sort the cartridges so that the rim end is always presented to the plunger, the shoot consisting of two plates j<4> which are too close together to permit of the rim of a cartridge passing between them.

Title: Improvements relating to prepayment meter mechanisms

Abstract: 562,093. Prepayment mechanism for meters. CHELTENHAM METERS, Ltd., and PORTER, J. Sept. 8, 1942, No. 12644. [Class 27] The control valve or switch of a meter is operated by a shaft d having a pin f adapted to engage notches k formed in the peripheries of two cams or discs g, h, so that when the notches coincide the pin enters the recesses and the valve &c. closes to cut off the supply. The spindles i, j of the discs are geared together by gear-wheels o having different numbers of teeth (e.g. one may have 20 teeth and the other 21), these gear-wheels being driven from the meter through a pinion p and an idler q.. The disc g is fixed on its spindle i, but the disc h is connected to its spindle j through a pawl n and ratchet m, so that it can be rotated thereon by means of a lever t also loose on the spindle and carrying pawls u, v engaging a ratchet-wheel s on the disc. When a coin is inserted in a slot 3 it falls down a shoot and rests, as shown at 6, against the end of the lever t and a fixed stop 5. A finger lever y is now depressed and rocks a lever w on the same shaft x, this lever forcing the coin down and thereby rocking the lever t so that the disc h is rotated through a certain angle and forces the pin f out of its notch thereby opening the meter valve. As gas is used, the meter drives the gear-wheels o, and the discs g, h rotate, but at different speeds, and the valve does not close until the notches coincide again after a number of revolutions of the discs depending on the ratio of the gears o. If two or more coins are inserted a corresponding additional quantity of gas will be available. When coins of different denominations are to be used, a corresponding number of coinadmission slots and finger levers are employed, the latter being adapted to impart movement to the disc corresponding to the value of the coin. In a modification, Figs. 4 to 7 (not shown), the discs or cams g, h are coaxial and the cam h drives an indicator showing the quantity of gas available and indicating when the maximum number of coins has been inserted.

Title: Improvements in or relating to process of preparing thiosemicarbazide
Filed: 1954-05-03
Abstract: Thiosemicarbazide is obtained by heating hydrazine with ammonium thiocyanate in aqueous solution, preferably under reflux. The reactants may be used in equimolecular proportions but it is desirable to have at least 2-3 mols. of thiocyanate present per mol. of hydrazine.  The former then exerts a buffering effect and keeps the pH at 7 or more.  Thiosemicarbazide separates on cooling the mixture and may be separated, dissolved in a water-miscible solvent such as ethanol and the solution diluted with water to precipitate the thiosemicarbazide.  Experimental details are given.

[Class 80 (iii)] [Also in Group XXXVII] A toggle lever mechanism, especially for electrical switches, consists of a leaf spring 1, Fig. 1, of shallow channel shape, having its ends connected to the parts to be controlled, represented by forces P, and which is released by a lateral force F, so that it suddenly bends into the shape shown in Fig. 3, thus ceasing to resist the forces P. The spring 1 may carry at its ends suitable bearing pieces for attachment to the parts to be actuated and the releasing force F may act on a lateral projection of each bearing piece. Two springs may be used together. their concave or convex surfaces being opposed and the releasing force F being applied by a rotatable lever or by a slidable cam member arranged between them. As applied to an electric switch the spring 1 has end pieces 6 connected to a bar 14 with push button 15 and to the movable contact 19. when the switch is closed it is held in that position against the action of the contact spring 18 by a catch 24 engaging a slot 23 in the bar 14. The catch 24 slides in a fixed plate 29 and is pivoted to a weighted lever 25 resting against a stop pin 28, the end 26 of the lever being located adjacent the upper piece 6. Projections 8 on the pieces 6 are engageable either by a hand operated rod 17 or electric solenoid actuated armature 21 to collapse the toggle 1 to open the switch contacts 19, 20. The engagement between the end piece 6 and lever end 26 disengages the catch 24 from the bar 14 and allows the toggle to straighten itself so that the switch is set ready for the knob 15 to be actuated to again engage the contacts 19, 20.
