Title: Improvements in or relating to pulse code modulation decoders
IPC: H03M1/00
Filed: 1962-12-18
Abstract: 949,297. Electric selective signalling systems. WESTERN ELECTRIC CO. Inc. Dec. 18, 1962 [Dec. 29, 1961], No. 47665/62. Heading G4H. [Also in Divisions H3 and H4] A digital to analogue converter for a P. C. M. system comprises means for scanning the pulse code train and storing the digits in a plurality of pulse distributor circuits - one for each digit of the pulse code -, means for supplying the stored digits simultaneously and individually to a plurality of switch driver circuits which control switches in the weighted reference branches of a current summation network to provide an analogue version of the input signal. As in Fig. 1 the decoder has four main parts - a timing circuit 12, the pulse distributor assembly 14, the switch driver assembly 16 and a weighted network 18. The incoming P. C. M. signal is applied along input line IN2 to each of the pulse distributor circuits (seven in number for a seven digit code). The timing circuit emits pulses D1-D8 sequentially at the pulse recurrence frequency. Each of the pulses D2-D8 are applied via lines IN1 to a respective pulse distributer circuit (Fig. 2) which is an AND gate so that if a digit is present in the IN2 line together with a D pulse along input IN1 (D8 in the circuit 37) the digit is effectively stored by charging of the capacitor 60. The arrival of the next D1 pulse, which is biased in the opposite direction to D2-D8, along input line IN3 causes the discharge of capacitor 60 and a positive voltage spike across resistor 66. This positive voltage is fed by line 23 to the associated switch driver circuit 39 causing the transistor Q1 to conduct which in turn switches transistor Q3 off thus emitting a switching pulse along line 24 to the weighted network 18. A further result of turning on Q1 is the switching on of transistor Q2 which expedites the switching off of Q3. Once Q3 is switched off it remains so for a time determined by the time constant of the RC circuit 76, 84 when the switch driver circuit 39 returns to its normal state (i.e. Q1 and Q2 off and Q3 on). The presence of a pulse in the output line of a switch driver circuit closes a switch in its associated branch of network 18 enabling a current flow from a voltage reference source. The branches are suitably weighted so that the sum output 10 from the network represents the analogue version of the input signal.

Abstract: 1414647 Filter element CARBORUNDUM CO 17 Oct 1972 [27 Oct 1971] 47773/72 Heading BID [Also in Division C6] A filter element for use in concentrating viruses from a fluid containing them and other particles comprises a fibrous filter medium formed into an annular filter element 11 having central passage 13, a layer of the filter medium being impregnated with a gel 17 which is capable of absorbing viruses from the fluid, the layer being substantially concentric with central passage 13 and contiguous with an unimpregnated portion of the filter medium. The gel may be formed from any polyvalent metal salt. The gel layer may be applied to a preformed support element or to a filter medium in the form of woven or non-woven material or as a roving, the medium then being wound on to a perforated tube. In use, the viruscontaining fluid flows radially through the filter element and the virus particles become absorbed on to the gel, the other particles passing through the element.

Abstract: 1481969 Valves WABCO WESTINGHOUSE GmbH 6 Nov 1974 [6 Nov 1973] 48099/74 Heading F2V A valve for a multi-circuit protection arrangement has a valve member 15 which is adjustably biased on to its seat 16 by a spring 27 and is provided with two concentric annular sealing lips 38, 39, the outer of which is shorter and the inner of which has breaks therein. On rise of pressure in the inlet 13 the lip 39 first lifts off the seat to allow a restricted flow through the gaps in the lip 38 to the outlet 11. Further pressure rise lifts the lip 38 off the seat and the pressure in the outlet acts on a diaphragm 25 to counteract the spring bias to hold the valve member off the seat. Two such valves are shown each having an inlet connected to a compressor and an outlet connected to a separate braking circuit including a reservoir. The arrangement is such that if either circuit becomes defective the other can be charged, the valve member of the defective circuit only lifting the lip 39 from the seat.

A shank lasting machine includes a support 57 for supporting a last 16 bottom up in the machine, a pair of hold-downs 14 which engage the toe and heel portions of the insole 18, a set of retarder plates 29 which initially, while in contact with the insole 18, move outwardly across the insole to raise the lasting margin 17<SP>11</SP> of the upper 17 and a set of wipers 40 which move inwardly to lay the lasting margin against the insole 18, the margin 17<SP>11</SP> being gripped between the wipers 40 and the retarders 29 to maintain the upper 17 in a taut condition. The hold downs 14 and the retarder assemblies 22 are carried by the piston rod 3a of a piston and cylinder device 3. The retarder assemblies are carried by brackets 21 pivoted to a collar 9 which is slidable on the piston rod 3a. Downward movement of the piston rod 3a initially causes the hold-down 14 and retarders 29 to engage the insole 18 and further movement causes a wedge 3a on the rod 3a to engage rods 33 on the brackets 21 to tilt the brackets 21 and thus move the retarders outwardly over the insole 18.

Normal focusing is achieved by rotating a ring 13 and attached part 19 to cause a member (12), Fig. 1, (not shown) to rotate, through a pin and slot connection (33, 34) to advance or retract the front lens group (I) through a threaded connection 35 on a fixed zoom tube 11. Zooming is achieved by sliding the ring 13 over the tube 11 to rotate and move axially a tube 23 carrying the second lens group (II) through the interaction of a pin 26 on the ring 23 with a channel 28 in the part 19 and a cam slot Z in the tube 11, relative axial motion between the rings 23 and 24 (which carries the third lens group (III)) being permitted by a slot 31 which accommodates a pin 30 on the ring 24. The pin 30 likewise moves in a cam slot Z1 to adjust the position of lens group III. For close focusing, the maximum focal length position, Fig. 1, is selected, whereby pins 26, 30 engage the slots S, S 1 , the pin 30 entering a recess (32) in a ring 18 lying within the part 19. In this position, an extension 25 on the ring 23 has forced a latch 41 out of a detent 40 in a selector ring 38 against a spring (43) to permit rotation of the ring 18 until the latch 41 engages a detent 39 in the ring 38, the pins 26, 30 being moved along the slots S, S 1  to enter cam slots M, M 1 , which provide equal movement of the tubes 23, 24, when the ring 13 is moved longitudinally.

In a disc brake having a rotatable disc 5 provided with friction pads 8 axially movable in holes through the disc and positioned between two non-rotatable brake discs 1, 2 at least one of the brake discs 2 is axially movable between a position in which the friction pads 8 engage the brake discs 1, 2 to a second position in which the rotatable disc 5 is released from the brake discs 1, 2 and the holes and/or friction pads are shaped so that in the released condition the friction pads can tilt in their holes such that the braking surfaces of the friction pads form an acute angle with the braking surfaces of the brake discs 1, 2. The tilting may be obtained by having cylindrical friction pads 8 as shown mounted in holes which have conically directed walls.
