Abstract: 1,228,349. Delivering sheets; endless conveyers. BROOKHIRST IGRANIC Ltd. 2 April, 1969 [12 April, 1968], No. 17196/69. Headings B8A and B8R. Delivering in counted batches.-Folded newspapers from a printing-machine are fed by belts 14, 16, 18, Fig. 2, past a counter 24 on to one of several pairs of blades 46 carried on chains 28, 30, Fig. 1, so as to form a batch, being guided below the next upward pair of blades by a member 22. When the counter indicates a predetermined number in the batch, the chains are moved to bring said next upward pair of blades down into the feed path, so that the following newspapers are delivered on to said blades, the member 22 being swung upwards by a solenoid SOL3 to allow this. After a delay, the chains are again moved to bring the upper blades into the original position of the lower blades, and the operation is repeated. This second movement causes the lower blades to move apart round the lower chain wheels and drop the completed batch on to a table 4 having a bottom formed of idler rollers 56, flared side members 54, Figs. 2 and 4, and resilient gate members 54a. If further batches are to be dropped on to the table to constitute a single stack, the table is rotated 180 degrees after each batch to compensate for the wedge shape of the batches. When the stack is complete, as indicated by a pre-set batches-in-stack counter, the stack is removed on to either one of the conveyers 8, 10, according to the setting of selector switches, by means of U-shaped pushers 74 carried on chains 60 which are moved in the requisite direction. The switches can be set to cause automatic alternate delivery to the conveyers 8, 10. While on the blades, the batches rest against a pair of back guides 50 and are aligned laterally by angled side guides 52.

Abstract: 1,232,022. Spray carburetters. STANDARDTRIUMPH MOTOR CO. Ltd. May 30, 1968 [March 2, 1967], No.9815/67. Heading F1B. The fuel nozzle 32 discharges into a primary air duct 12 to form a rich mixture which is subsequently mixed with secondary air flowing through the passage 11. A suction actuated piston 18 maintains a constant suction downstream thereof and carries a tapered fuel metering needle 26 the upper portion 27 of which is cylindrical to avoid leakage of air from passage 11 to passage 12 when piston 18 is in its lowest position. Mixture enrichment for starting is obtained by rotation of a member 33b which lifts the position 18 to increase the fuel supply but blocks the space beneath the piston to prevent any increase of airflow. The carburetter is attached at 16 to a mixture passage leading to the cylinders of the construction described in Specification 1,232,021.

Abstract: 1,232,360. Automatic phase lock. FUJITSU Ltd. 25 June, 1969 [25 June, 1968], No. 32186/69. Heading H3A. In a bit synchronization circuit in which a local oscillator is phase locked to the incoming data signal, the oscillator phase control signal is inhibited when the received signal-to-noise ratio falls below a predetermined level. In one embodiment, Fig. 2, the received signal is fed to a delay circuit 7 in which capacitor C has a short time constant charging path and a long time constant discharging path. The output from the delay circuit is fed to a gate 8 to disconnect the signal input to phase comparator 3 when the signal-to-noise ratio is too low. In a first modification of the delay circuit, Fig. 4 (not shown), two capacitors are employed, one having a short time constant charge and discharge path and the other a long one. In a second modification, Fig. 5 (not shown), this short time constant is made zero by omitting one of the capacitors. The synchronization circuit, Fig. 1, comprises an input stage 2 tuned to the bit frequency, a limiter 2<SP>1</SP> to square the output from the stage 2 and a phase comparator 3 fed with the output from the limiter 2<SP>1</SP> and the local oscillator 5. The output from the phase comparator is used to control a varactor VC in the tuned circuit of the oscillator. In a modification of Fig. 2, the signal to the delay circuit is taken from the output of stage 2, Fig. 8 (not shown).

Abstract: 1,239,623. Fastener driving tools. SWING- LINE Inc. 4 July, 1968 [4 Dec., 1967], No. 31844/68. Heading B4C. [Also in Division B8] In a pneumatically operable fastener driving device a string of fasteners, e.g. nails is housed in a storage container 67 (Fig. 21) and the fasteners are advanced to a fastener driving position by a reciprocable pawl member 48 (Fig. 19). Reciprocation of the pawl member is effected by compressed air acting on piston 44 to advance the fasteners and by a spring 59 to return the pawl member when the space behind the piston is vented to atmosphere. A retaining member 60 (Fig. 17) is provided with projections 61, which permit advance only of the fasteners. An alternative form of retaining member is illustrated in Fig. 6. The storage container includes a body portion 69 and a lid portion 71 which are locked together by a coupling member 89. An arm 90 of the coupling member is located in a detent (75) (Fig. 1, not shown) in the lid portion and a hooked end 91 of the coupling member is located in one of three apertures 82 in a hollow stem 78 connected to a stem 70 by a screw 81 locatable in any of three apertures 80 in the stem 70. Thus the container may be adapted for fasteners of different lengths. Initially a string of fasteners is placed in the container 67, a pivoted door 92 is opened and the leading fasteners are positioned as illustrated in Fig. 19. Then compressed air is supplied to reservoir 31 and via passages 30, 33, 34 (Fig. 7) to either side of a valve member 20 and to bore 43. Thus the piston 44 moves to advance the pawl member so as to position the leading fastener in passage 100. Upon actuation of trigger 39 the bore 43 and passages 33, 34 are vented to atmosphere, and thus the pawl member is returned by spring 59 and the valve member 20 is raised by air pressure acting on its under surface. Compressed air then forces driver piston 12 on a driving stroke. Upon release of the trigger compressed air is admitted to passage 33 and bore 43, and the valve member is urged downwardly and opens a vent 27. The driver piston is returned by spring 19, and the the fastener string is again advanced.

Abstract: 1,258,794. Endless conveyers for tubular cans: USM CORP. 23 May, 1969 [24 May, 1968], No. 26365/69. Heading B8A. Tubular articles B are conveyed from a receiving station (Fig. 7) to an ejection station (Fig. 1) by a plurality of drive lugs 62 each provided with a leg 64 for engaging a trailing edge portion of an article B.. The leg 64 is provided with article engaging projections 80, 84, extending in spaced relation to the lug 62, whereby a leading edge portion of an article and a trailing edge portion of a preceding article, can be received between the respective projections 80, 84, and the lug 62. Lug positioning means (a cam surface 72) are provided whereby the leg 64 of each drive lug can be moved into an operative condition. Lug maintaining means (horizontal cam surface 42) enable each drive lug 62 to be maintained in the operative condition as it moves along from the receiving station to the ejection station. At the latter station a pair of a series of eight pairs, of arms 90 mounted on the conveyer drive sprocket 30, are brought into position by-the action of a cam 114 carried by the conveyer framework. In this way the arms 90 engage, on opposite sides of a lug 62, between the rear edge of the leading cam and the leading edge of the following cam. As the cam is accelerated away by the action of the arms 90, an abutment 120 on the sprocket 30 (there are eight such abutments on the sprocket) engages a cam portion 66 of the lug 62 and causes the latter to be pivoted into a retracted position and to cause its projection 80 to be disengaged from the following can. In. a modification (Fig. 8, not shown), the projection 84 is dispensed with. In another modification (Fig. 9, not shown), there is a downwardly sipping section (42a) of the lug maintaining means 42; following the lug positioning means 72. The cam portion 66 of each lug, is replaced by spaced cam surfaces (266), (268).
