The braking means 8, carried by the lever 7, has a brake friction surface 15 mounted on a resilient member 14 to supply braking force by contact with the track 2. The shape of the cam plate 5 is such that progressively increasing braking force is applied during the initial stages of contact of the roller 9 with the cam plate 5, but braking force is reduced below its maximum value before a resilient ultimate stop 10 on the trolley contacts the cam plate 5. Each carrier trolley may have a hold-back device 16 to prevent the trolley from travelling faster than the chain 22 and each trolley may comprise several coupled trolley members, the leading member of which includes the dog 6.

Abstract: 1308744 Cathode-ray tubes; electron multipliers NORTHROP CORP 23 June 1971 29464/71 Addition to 1174038 Heading H1D A cathode-ray tube of the type described in Specification 1,174,038 is characterized in that each dynode 17-19, Fig. 3, is provided with electrodes arranged in different finger patterns on each side. In Fig. 3, the first dynode is provided on one face with two vertical strip electrodes 31a and 31b connected to a flip-flop 56, and on the other face with two horizontal strip electrodes 32a and 32b connected to a flip-flop 57. With the potentials shown, electrons from the cathode 13 can pass through the apertures only in the top left quadrant, since in the other quadrants there is no accelerating field across the dynode. Similarly electrodes 18 and 19 have different finger patterns on opposite faces, so that a matrix of 8 x 8 apertures may be controlled by only three dynodes. The finger patterns illustrated are for use with Gray code, but alternative patterns could be provided for ordinary binary code. In a modification, Fig. 5 (not shown), the electrodes on each face of each dynode are arranged in four groups each connected to a respective flip-flop; a 16 Î 16 matrix may then be controlled by only two dynodes.

Abstract: 1309731 Rotary drum vacuum filter DAVEY PAXMAN & CO Ltd 24 March 1970 [24 Dec 1968] 61335/68 Heading B1D In a rotary drum vacuum filter comprising an endless belt 1, shown as the filter cloth but alternatively being arranged to apply pressure to material on the drum surface, the belt is automatically adjusted to compensate for lateral movement and for any tendency for one edge of the belt to move ahead of the other. The belt is also constructed of panels 2, sewn together along transverse lines 3, and reinforced by edge strips 4 to resist stretching. Each edge of the belt is normally gripped by a pair of rollers 10, 11 mounted on inclined shafts so as to pull the edges outwards, but if one edge moves sufficiently to engage a feeler 18, this closes a micro-switch which controls a pneumatic device to lift the corresponding roller 11 off the belt so that the rollers at the opposite edge pull the belt back. Before returning to the drum 6, the belt passes over roller 22, whose opposite ends are vertically adjustable in frames 25, by handwheels 26 and by pneumatic rams 31. Metal plates 46 are sewn into opposite edge portions of the belt, and any misalignment thereof is detected by magnetic heads 44, which then operate a solenoid valve (Fig. 2 not shown) which supplies air to opposite ends of rams 31 to tilt roller 22 and correct the misalignment. As shown, belt 1 is a filter belt which discharges cake in passing round roller 8 and is washed by water from spray pipe 19 and tensioned by contact with tube 20.

Title: Telephone accessory equipment
IPC: H04M1/658
Filed: 1970-05-01
Abstract: 1313404 Substation apparatus E R SALZBERG 1 May 1970 21149/70 Heading H4K A telephone answering device responds to the receipt of an incoming call on a first line by seizing a second subscriber line, dialling out a transfer number on this second line and reverting to the caller a recorded message and interconnecting the first and second lines when ringing or busy tone is sensed. In the equipment shown, the transfer number is recorded on magnetic drum 12 by interrupting oscillator OSC output in accordance with dial pulses and the recorded message is recorded by means of microphone 20 and amplifier 22 feeding recording head 24. Both the dial pulses and message are recorded such that they can be replayed simultaneously during one revolution of the drum. The incoming call on L1, L2 is detected initially by relay E which brings up a relay F to seize the outgoing line L3, L4 by closure of contact f 2 . Relay D closes after a time delay sufficient for dialling tone to have appeared on L3, L4 and starts the drum rotating as well as seizing lines L1, L2 by choke CH2. The recorded dial pulses are sensed by lead 40 and operate relay H whose contact h1 applies the interrupt pulses to lines L3, L4. At the same time the recorded message is sent by head 30 to the caller on lines L1, L2. Ringing tone is sensed at 44 to bring up relay J which causes relay Z to operate and connect line L1, L2 to line L3, L4 through amplifier 48. If engaged tone wave sensed relay IT would operate by winding K<SP>1</SP> to reset the device. After 1 minute of ringing tone or 5 seconds of busy tone the disconnect relay IT operates. Similarly when the call is ended dialling tone is sensed by sensor 46 which operates the disconnect relay 46. The transfer number may be charged from a remote location by the caller injecting a tone on to the lines L1, L2 (e.g. by a whistle) which is sensed at 50 to operate relay M and release the line L3, L4 as well as connecting in the recording circuitry to head 18. Dially pulses on the lines L1, L2 are sensed at 54 to operate relay P which interrupts the output of the oscillator. The dialling information may be tones. Alarm system.-Operation of a fire or burglar sensor contact causes of line L3, L4 to be seized and the recorded number is dialled out as before. In this case if the engaged tone is received relay V is operated to cause the number to be repetitively dialled until a connection is made.

Abstract: 1337041 Measuring visibility DEFENCE SECRETARY OF STATE FOR 13 Jan 1972 [15 Jan 1971] 2096/71 Heading G1A In an apparatus for measuring visibility including a light source 4 and a detector 6 receiving scattered light the angle of intersection of light beam 5 and the field or view of the detector 6 and the distance of the point of intersection from the detector are kept constant but the point of intersection is caused to scan the atmosphere by rotating the source 4 and detector 6 together on a shaft 1, Fig.1, as shown, or by keeping the source and detector stationary on either side of two mirrors mounted on opposite ends of a horizontal rotatable shaft Fig.2, (not shown). Alternatively, the position of the two mirrors and the source and detector may be reversed with the mirrors stationary. The shaft in the Fig.1 arrangement may be omitted and the source and detector coupled together by the follow-up servosystem so that they move in synchronism with each other. The instrument may be calibrated by rotating the beams to a horizontal position and comparing the measurements made along ground level paths by a transmissometer of conventional type. Since in this invention the detected light intensity varies as a function of fog density which rises to a peak at a particular value of fog density and then decreases for denser fog, there is the possibility of ambiguous measurements and a second detector may be provided and mounted so that it receives light scattered from within the first beam path but from a different part of said beam. The detector's outputs may then be used to eliminate any ambiguity
