Abstract: 1,225,659. Packaging - machines. A. SCHMERMUND. 18 July, 1969 [14 Aug., 1969], No. 38786/68. Heading B8C. In a cigarette packing machine which serves to position alternate rows of fifty and fifty one cigarettes into a container S, cigarettes are fed, by means of a feed belt 31 and a drum 34 having suction troughs 32, on to the grooves of a pair of multi-start screw spindles 1, 2, driven by a servocontrolled motor M, and are held stationary for a fraction of a second while a line of cigarettes is removed by a suction plate arrangement comprising a withdrawable centre part 7 having a single cigarette receiving trough and two lateral parts 5, 6 each having twenty five troughs. In order to pick up fifty cigarettes from the spindles 1, 2 the plates 5, 6 are moved laterally together by cams 25 and linkage 23, 26 to displace the centre part 7 upwardly, and are connected to a source of suction before being lowered, by cams 20 and follower linkage 15, 17 to pick up fifty cigarettes from the spindles 1, 2 as the latter are momentarily stopped, the spacing of the cigarettes 4 on the conveyer 31 allowing feed by the drum 34 to continue without piling up cigarettes behind the drum 34. The cams 20 then raise the suction plates 5, 6 which are subsequently moved to the left, Fig. 3, by means of cranks 12, directly above a container 34, the spindles 1, 2 being rotated again immediately after the pick-up of the cigarettes, and the suction plates 5, 6 being lowered, as the cams 20 continue to rotate, to deposit the fifty cigarettes in the container S4 on top of the preceding row of fifty one cigarettes, in staggered relation, as suction to the plates 5, 6 is cut off. On release of the cigarettes the cams 20 raise the plates 5, 6 and the crank 12 returns the plates to position them above the feed spindles 1, 2 as the centre part 7, connected to the plates 5, 6 by a parallel linkage 10, 11, is lowered to extend between the plates 5, 6 by the cams 25, so that, when the suction plate 5, 6, 7 is lowered again to repeat the packing operations, it picks up fifty one cigarettes, the spindles 1, 2 feeding the cigarettes, this time, through a distance more than the previous feeding action by one half the diameter of a cigarette. The container S4 is lowered after each layer of cigarettes has been deposited, by a stepping mechanism, the containers S 1 -S 8  being moved by conveyers and pushers in directions indicated by arrows in Fig. 3. A segmental core 45 in the drum 34 blocks off suction holes 44 which are not required to convey cigarettes at any one time the drum 34 also having grooves 47 in which strippers 48 engage. A curved carry-over member 49 assists in the transfer of cigarettes which are guided by rails 51. In a modification, Fig. 6, not shown, the spindles 1, 2 are replaced by a troughed belt (101). Both spindles 1, 2 and troughed belt can be modified to carry cigarettes of different diameters, and the suction plate may have only two parts instead of three.

Abstract: 1,232,400. Anti-siphon means for pumps. PORT OF LONDON AUTHORITY. March 13, 1969 [Dec.22, 1967], No.58405/67. Heading F1C. An anti-siphon valve mounted on the crown of a siphon discharge tube of a pump is mechanically biased to the open position and provided with means to open and close it, the means for closing it being arranged to come into operation only when the pump is operated, and there being means for providing a delay between the commencement of pump operation and the operation of the valve closing means. The anti-siphon valve 1 is biased towards the open position shown by a spring or a counterweight 2. When the electrically driven pump (not shown) is started, a solenoid valve 18 electrically connected with the pump opens to admit high-pressure air via time-delay means comprising a uni-directional port 17 and an air reservoir 16 to an air-operated valve 12 to open the latter. The valve 12 then admits high-pressure air from a line 14 to a line 13 to move a valve 8 against the action of a spring 9 into the position shown, in which it admits highpressure air from a line 10 into the left-hand side of a cylinder 5 to cause a piston 4 to close the antisiphon valve 1, and also vents the right-hand side of the cylinder to atmosphere. The time delay permits the discharge of air and formation of the siphon. In cessation of pump operation, the valve 8 reverts to its normal position and admits lowpressure air from a line 11 to the right-hand side of the cylinder 5 to open the anti-siphon valve 1 and also vents the left-hand side of the cylinder to atmosphere. In the event of failure of the electrical supply or the air supply, the system fails safe, with reversion of the anti-siphon valve 1 to its open position. To guard against mechanical failure, position-indicating switches may be mounted on the spindle of the anti-siphon valve 1 to transmit a warning to a control room. Instead of being pneumatically operated, the anti-siphon valve may be opened and closed by a pair of opposed solenoids, an electrical time-delay means being used to ensure delay of operation of the solenoid for effecting closure.

Abstract: 1294836 Transistor pulse circuits; repeater amplifiers H DUTTON HAYWARD J SCHULEIN and MASCHULEIN 17 March 1971 7136/71 Headings H3T and H4R [Also in Division G4] In a shared-transmission medium signalling system, a plurality of receivers distinguish signals from respective transmitters from signals from the other transmitters by pulse height. A plurality of transmitters are connected over a common line-pair including a line amplifier to respective receivers. At a transmitter, detection of a burglar starts a multivibrator to supply, via a pulse shaper to the line-pair, a train of pulses each of the same amplitude set by a potentiometer and characteristic of the transmitter. Thus different transmitters use different prfs to reduce interference between pulse trains from different transmitters. At a receiver (Fig. 3) an incoming pulse at 26, 28, as long as its amplitude exceeds a threshold defined by potentiometer 96, produces a signal at 120 by conduction of transistor 84, provided it does not exceed the threshold by more than an amount defined by diode 106 which would cause transistor 86 to conduct to cut off transistor 84. The signal at 120 charges capacitor 118 and provided it lasts long enough, transistors 114, 116 conduct to light lamp 132, the conduction being sustained via resistor 130 (and can be ended by means not shown to extinguish the lamp). Compensating for stray capacitance on the linepair (Fig. 5).-A pulse across line-pair 24, 28, is amplified 30 and applied to capacitor 156. After a time delay defined by charging of this capacitor, SCR 148 conducts to short the line-pair, abruptly terminating the pulse, capacitor 156 discharging via diode 162.
