When the lever A<SP>1</SP> is moving clockwise, it engages a pin a<SP>5</SP> on the switch plate A<SP>2</SP> to move the switch plate and pointer clockwise. When the lever A' moves anticlockwise the leafspring A<SP>3</SP> connecting the lever A<SP>1</SP> to the switch plate A<SP>2</SP> causes corresponding movement of the switch plate A<SP>2</SP> and the pointer A. The switch D<SP>1</SP> may be of the mercury type and is adjustable in a slotted member d relatively to the scale. When the switch D<SP>1</SP> has been adjusted to a new position the switch plate A<SP>2</SP> and consequently the pointer A may be moved manually clockwise by means of a pivoted arm D<SP>3</SP> engageable with the switch plate A<SP>2</SP> to check the setting at which the switch will operate, flexure of the leaf-spring A<SP>3</SP> permitting this motion to be made without disconnecting the link a<SP>1</SP> between the lever A<SP>1</SP> and the control coil B. The arm D<SP>3</SP> may be turned by a knob external to the casing of the gauge. A telltale pointer A<SP>4</SP> may be used to indicate the maximum movement of the pointer A, the telltale pointer A<SP>4</SP> being moved by a pin a' depending from the pointer A and being returned to zero when desired by an anticlockwise move. ment of said knob causing a wire attached to the pivot of the lever D<SP>3</SP> to engage and move the tail end of the pointer A<SP>4</SP>. The coil B may be a Bourdon tube.

Abstract: 670,901. Applying closures to cans. CONTINENTAL CAN CO., Inc. Jan. 26, 1950 [Feb. 17, 1949], No. 2112/50. Class 125(ii) In an apparatus for removing air from the head spaces of filled cans, whilst cover and can complements are conveyed towards a closing means with each cover disposed over and spaced from the open top of its can, means are provided for directing a gas (steam or inert gas) into the space between each cover and can to expel air therefrom, the means being so located and directed that the gas stream splits, as shown in Fig. 10, on each can flange, a portion of the gas being deflected downwardly over the can wall to prevent an upward movement of air towards the space which is cleared of air by the undeflected portion of gas. The gas jets, which may be arranged to direct parallel streams across the top of the can, or as shown in Fig. 9, as two side sets 26 and a central set 25, are formed in an arcuate plate'18 arranged at the top of each canreceiving pocket 16 in the turret plate 14. The gas is supplied by a pipe 62 to a port passage 61 extending for about 120 degrees around a stationary sleeve 43, the ports 40 in the rotary central core 37 registering in succession with the port 61 to connect the corresponding jet plates 18 through the passages 23, 44 to the gas supply 62. The filled cans are fed to the turret plate 14 by a conveyer A passing through a steam tunnel 67, and the covers 72 are dropped singly, e.g. by screws 73 on to inner and outer rails 74, 75 over which they are pushed, by enagement with the higher of two lugs 33, 34, Fig. 5, secured at the sides of each recess 16, through a marking station C, Fig. 1. Whilst moving over the rails, the covers are engaged by frictional retarding means for restoring engagement of the covers with the higher lugs 33, if the marking device momentarily moves them in advance of the lugs. The conveyer A feeds the cans under an insulated turret guard plate 50 having guide means which receive the covers from the guides 74, 75 and are sloped to drop them upon the tops of the jet plates 18, the outer parts of the covers being then supported by a guide rail 96. At the sloped parts of the guides, the top of each cover is engaged by ribs 113 on a spring-pressed shoe 108 carried by the guard plate 50, the cover being thus retarded and prevented from bouncing over the low lug 34, the accurate location of the cover between the lugs 33, 34 ensuring alignment of the cover with the can. The guides for the partly assembled covers and cans are gapped at 117, 118 to permit the cans and covers to be raised, and to permit the pads of the closing turret F to go down through the guides and engage the covers on the rising cans.

Title: Improved electric burglar-alarm
IPC: G08B13/22
Filed: 1945-01-31
Abstract: 589,369. Burglar and like alarms. HORVITCH, G. M. Jan. 31, 1945, No. 2431. [Classes 40 (i) and 118 (i)] [Also in Group XXXVII] An electrical burglar alarm system comprises a detector resistor 1 and a shunt resistor 4 at each point of possible entry, an indicating meter 18, a bell 27 and a buzzer 28. By means of a mechanically-locking switch 7 entry at a point " A " shorts out the detector and shunt resistors 1, 4 moving the meter pointer 21 to the right to indicate point a' on the scale 26 and close a self-locking bell circuit at contact 25. A break in the portion of the circuit containing the detector and shunt resistors 1, 4 .... 3, 6 moves the meter pointer 21 to the left and closes a self-locking buzzer circuit at contact 24. A compensating rheostat 15 keeps the system in correct calibration. The switch 7, Fig. 1. may be mounted in the frame of a door or window and opening the door or window 60 (Fig. 2) releases a spring-urged. plunger 31 whose lug 32 strikes a pivoted lug 43 to swing an operating member 40 clockwise about its pivot 41. The top portion of the operating member 40 is thus forced between two spring contacts 35 to short-circuit the detector resistance 1 which may be mounted within the switch casing. The operating member is retained in this operative position against the pull of a return-spring 42 by the frictional grip of 'the contact springs 35. Subsequent retraction of the plunger 31 has no effect on the operating member 40 since this should be clear of the plunger lug 32. Should the operating member be imperfectly retained by the contact springs 35, however, any return movement of the plunger 31 may cause the plunger lug 32 to strike the lug 43, but this, being pivoted, will ride over the plunger lug 32 without disturbing the operating member 40. The switch can be re-set only by screwing a threaded cylindrical key into an annulus 56 to force out a rod 49 and so move the operating member 40 counter-clockwise about its pivot 41.
