Abstract: 1,233,042. Time switches. J. P. NORMAN. 5 Feb., 1969 [5 Feb., 1968], No. 5668/68. Addition to 1,211,007. Heading H1N. A programme for burglar alarm systems, for example, comprising a 24-hour dial 1 carrying wiping contacts 2 and 3 co-operating respectively with fixed contacts 4 and 5, has an auxiliary microswitch 15 which is closed each half-hour when a follower roller 13 seats in depressions 12 around the edge of a disc 9 attached to dial 1. Switch 15 may thus be used to ensure that current only passes for short periods between successive changeovers of contacts 2 to 5, i.e. while the moving contacts are unequivocally engaged or disengaged with fixed contacts. The dial 1 is adjustable on its shaft 6 and carries time-of-day indicia 7 which are read at a fixed point 8. The dial 1 also carries two pins 18 which step a fourteenpointed star-wheel 17, located by a roller 21 and carrying a wiper co-operating with fixed contacts whereby contacts 4 are only operative on those days selected by push-buttons 22. The star-wheel 17 may be manually set to an intermediate position wherein the arm 20 carrying roller 21 acts on the arm 14 to lift roller 13 while dial 1 is being reset. The wiping contacts 2 and 3 correspond to the first rotor of the parent Specification while the disc 9 corresponds to the cam 17, and wheel 17 and buttons 22 are analogous to the second rotor and terminals 5 and 11.

Abstract: 1,252,184. Valves. VARIAN ASSOCIATES. 3 Feb., 1969 [19 Feb., 1968], No. 5762/69. Heading F2V. [Also in Division F1] A valve which is designed to place an apparatus in communication either with vacuum or with atmosphere, is connected to the apparatus via a line 24, has its body 6 disposed within a vacuum manifold 3, and includes a spring-biased plunger 14, the degree of movement of which plunger may be varied. With the plunger in the position shown, and in the absence of the vacuum seal provided by the depicted operator's finger, the apparatus communicates with atmosphere via line 24 and passages 27 and 28. Upon establishment of such a vacuum seal and subsequent depression of the plunger 14 from its uppermost, seated position, communication with atmosphere is interrupted and the apparatus is connected to vacuum via line 24 and passages 21. The innermost end of the passage 28 is threaded to receive a suitably threaded sleeve, the interior of which sleeve constitutes passage 27, and the innermost end of line 24 has extending thereacross a pin 26, the sleeve and pin co-acting to form a stop for limiting the extent of plunger downward movement, adjustment of such extent being achieved by appropriate manipulation, through the free end of passage 28, of the sleeve.

Abstract: 1,252,746. Gear pumps. BARMAG BARMER MASCHINENFABRIK A. G. Dec. 2, 1968 [Dec. 23, 1967], No. 57016/68. Heading F1F. A gear pump particularly for spinning artificial fibres, comprises pump sets 5, 2, Fig. 2, separated from each other by intermediate plates 3, 4, having drive wheels 9, 10 secured one behind the other to a common drive-shaft 8 and driven wheels 15, 13 freely mounted on solid and hollow pins 16, 14 respectively with the bore of the hollow pin connected by transverse and longitudinal ducts 19, 18, Fig. 1, in the plate to the discharge side of the intermeshing gears 9, 15 of the pump set 5 to serve as a delivery duct. With this arrangement of ducts, the gear-wheels are relieved of axial pressure from the liquid being delivered from the pump set 5 thus reducing pump wear and at the same the delivery flow travels along a short path. In another construction, the driven wheels of each pump set are each associated with a pair of driven wheels with the driven wheels of one pump set freely mounted on solid pins and the driven wheels of the other pump set freely mounted on hollow pins. The number of pump sets are not necessarly limited to two.

Abstract: 1,252,922. Fluid-pressure synchronizing systems, automatic speed-control. ALBRO FILLERS & ENG. CO. Ltd. Jan.31, 1969 [Feb. 1, 1968], No.5278/68. Headings G3P and G3R. Synchronous operation of a series of machines 1-3 in a bottling plant, and of screw feeders 14-16 driven by the respective machines, is obtained by means of sensors S between each adjacent pair of feeders which detect speed variations between the feeders and restore synchronism by adjusting respective valves 13 which control the flow to hydraulic motors 5, 6 from pump 9. Motor 4 driving machine 1 serves as the master for this system. The sensors may comprise Fig.3 a helical track 20 on one feeder shaft 14 which co-operates with a pin 22 carried by a sleeve 21 slidably keyed to the other shaft 15, such that relative rotation causes axial adjustment of sleeve 21 and finger 23 to actuate a spool valve controlling valve 13. Machine 3 may have a separate pump for its motor 6. In Fig. 7, pneumatic pulse generators 26-28 driven by two of the machines have their outputs fed to pneumatic flip-flop 29 which, when supplied with air from AND gate 30 supplies air to flip-flop 32 whose air source X 3  is directed to piston 33 to restore synchronism. In an electrical equivalent of Fig. 7, rotating magnets co-operate with reed switches controlling a solid-state switching network which actuates a solenoid valve to restore synchronism. The Fig.3 sensor could alternatively control valve 12 through a leak-off pilot valve. In Fig. 1 (not shown) machines 1-3 are driven by serially arranged hydraulic motors (4-6) whose speeds are controlled by sensors (11, 12 or 11a, 12a), which detect crowding or separation of the bottles on feed conveyer (10), and control valves 13. These sensors can be hinged gates, air jets or light-beams.

As shown the rotary device is a disc (which may be circular, ellipitical or near-symmetrical) adjustable on shaft 5 and there may be stirrers 7 adjacent the wall attached to the disc 6 or shaft 5 or on a separate shaft. The apparatus may be used for mixing solids with solids or liquids, catalysed chemical reactions, drying particulate solids, roasting, and evaporating solutions or dispersions. The embodiment depicted is intended for evaporation, there being liquid inlets 8 at disc level; gas and particulate solids are discharged at 10 and separated e.g. in a cyclone.

Abstract: 1355649 Television BRITISH BROADCASTING CORP 27 July 1972 [27 July 1971] 35312/71 Heading H4F A television signal is recorded on magnetic tape in analogue form, the read-out signal being sampled to provide an analogue or digital sampled signal, the sampling being controlled by clock pulses timed by a pilot signal which is either derived via a band-pass filter from a signal added to the television signal prior to recording, or is read out from a separate track on the magnetic tape, or is derived from the sync. signals and colour bursts of a replayed colour television signal. Approximate timing of the clock pulses may be achieved using the sync. signals of the replayed television signal, accurately timing them taking place relative to the pilot signal. As shown the read-out signal is sampled in an analogue to digital converter 26 and the clock pulses also control read-in of the sampled signal to a store 28, read-out from the store being controlled by read-out pulses from 32, derived from local reference signals, to eliminate timing errors in the replayed signal. A signal from store 28 indicative of the difference in timing between the clock pulses from 24 and the read out pulses from 32 may also be fed to a control circuit 38 to control the speed of the videotape machine 16 to keep timing errors within the limits with which store 28 can cope. Store 28 may be replaced by a variable delay line controlled by the signal indicative of the timing differences between the pulses from 24 and 32. In the event of drop-out store 28 is arranged to insert either a signal delayed by one line interval, or the value of the signal immediately prior to drop-out.
