Filed: 1962-08-02
Abstract: 944,392. Counter scales. W. & T. AVERY Ltd. Aug. 2,1962, No. 29652/62. Heading G1W. A counter scale, which may utilize a Roberval, Beranger or like lever system, comprises a load counterbalancing weight mounted for rolling movement along a lever so as to vary the moment in opposition to a load on the scale, the position of the weight being manually controlled by a handle disposed externally of the housing and being movable in one direction to unlock the weight and rotatable in a second direction to move the weight. As shown Fig. 1 the handle 1 when moved in the unlocking direction 'A' pushes against a plunger shaft 5, in a hollow drive shaft 6, thereby moving a slidable collar 7 to which plunger 5 is fixed by a pin through a slot in shaft 6. The collar 7 moves, in an anti-clockwise direction, the lever 8 which is pivoted at B. The said movement of lever 8 does two things. Firstly, it pulls, via a cable 10, the lever 12 into engagement with a crank 13 to cause the crank to raise a spring loaded wheel 3 (Fig. 2) from a toothed rack 14 carried by the roller weight 4 thereby freeing the roller weight. Secondly, it disengages a wedge shaped end of a lever 9 from a gear-wheel 2, thus freeing the gear-wheel. Rotation of the handle 1 turns the drive shaft 6, gear-wheel 2 and a combined gearwheel and pulley 16, and by means of a cable 17 from pulley 16 moves the roller weight,the cable passing round a pulley 18 and being anchored to the roller weight. A further cable 23 connects the gear-wheel 2 to an indicating mechanism (not shown) the graduations of the indicator being directly proportional to the tooth pitch of the rack 14. The roller weight 4 moves on rollers along two rails 20, 21 mounted on two parallel arms of a main weighing lever 32. The lever 32 is coupled at 33 to a weigh platform (not shown) and at 34 to a load indicating headwork (not shown).

Abstract: 226,526. Soc. Anon. Solex. Dec. 19, 1923, [Convention date]. Spray corburettors.-In multi-jet carburettors means are provided to increase the output of the auxiliary nozzle at the end of the slow-running period, and to reduce its output at high speeds. This is effected by providing the throttle valve f, Fig. 6 with an enlargement f<1> which obstructs the outlet from the auxiliary mixture passage e. the lower portion of the enlargement being substantially on a level with the axis of the valve in the closed position. As the throttle is opened, the upper edge of the enlargement f<1> recedes from the wall of the body d, but the lower edge remains adjacent 'thereto, so that the output of the auxiliary nozzle progressively increases dur ing this period, the output decreasing when the enlargement passes above the outlet. In a modification, the passage e opens into the body d both adjacent the edge of the closed throttle and also at a point on the engine side thereof, a valve being provided to control simultaneously an air inlet and the connection between this second outlet and the passage e. This outlet supplies rich mixture for starting, the throttle being kept closed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also (1) a modification of the construction shown in Fig. 6, in which the outlet from the passage e is adjustable in height, and consists of an eccentric passage in a rotary plug, the passage opening into an annular groove in the plug which communicates with the passage e.

Abstract: 396,367. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Oct. 29, 1931, No. 30033. 'Convention date, Nov. 8, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (iv).] In a system in which the initial locking circuit of the switching relay CR of the line switch includes a normal contact 3 of the subsequent selector, a permanent lock-up is liable to occur should the line relay BR of the selector fail to energize due to the subscriber hanging up at the moment of switching through or due to some fault. Several arrangements are described for obviating this defect. In Fig. 1, relay GR which energizes in the test circuit closes a local circuit through resistance R2 for line relay BR which connects up relay ER. The test circuit is transferred at contact 9 through resistance R1 and relay GR falls back, followed by relays BR, ER if the loop is open at this stage, and relay FR energizes momentarily. Contact 9 is restored, but the original test circuit is opened at contact 12 for a time sufficient to ensure release of relay CR. In Fig. 2, relay GR connects up relay ER directly, the operation being otherwise the same as in Fig. 1. As a modification, the switching relay CR may be a twostep relay, which does not complete its locking circuit at contact 5 until the test circuit is transferred at contact 9 through resistance R1 by the operation of relays BR, ER. Relay GR may in this case be replaced by a resistance.
