Title: Signal transmission system
IPC: H03M3/02
Filed: 1974-10-17
Abstract: 1481464 Differential pulse code modulation encoding and decoding INTERNATIONAL STANDARD ELECTRIC CORP 17 Oct 1974 [7 Nov 1973] 45044/74 Heading H3H In a differential pulse code modulation receiver, Fig. 4, the output of the add-and-delayloop demodulator Add 2, L4 is routed to one or more inputs of a chain of delays L5-Lm - 1 selected by a counter Z incremented by one whenever two consecutive maximum transmissible difference values # max  are received at E2 and reset to 1 when either of the last two received values is not # max . Thus a sudden jump exceeding 2# max  in the original signal is reproduced at a single clock instant at the receiver by allowing the loop Add 2, L4 to accumulate the # max  values and applying the result with appropriately reduced delay to digital-toanalogue converter W2. When counter Z is in position n, the first n delay stages receive inputs, the first (n - 1) stages being inhibited from passing the signal to the next stage. Counter Z resets to 1 if it overflows its last position m corresponding to the end of the delay chain. The transmitter, Fig. 3, includes an arrangement to prevent overshoot in the receiver. The encoder comprises an analogue-to-digital converter W1, subtractor Diff 1, 8-to-4 bit converter CW1, 4-to-8 bit converter CW2, and a summing loop comprising an adder Add 1 and delay L1 connected to feed back to the subtractor Diff 1. # max  detectors CE1, CE2, delay L2 and gate U5 detect the condition "value to be transmitted equal to # max  and previously transmitted value not equal to # max " and cause the then output, x, of W1 to be stored at Sp. The feedback signal, y, is subtracted from x at Diff 2 and if (x - y) falls below # max , a special code sk is transmitted instead of the actual value of the D.P.C.M. signal. The code sk may be # max-1  whose arrival at the receiver will cause counter Z to be reset to 1.

Abstract: 1,026,068. Jet propulsion nozzles. ROLLSROYCE Ltd. Nov. 9, 1964, No. 45670/64. Heading F1J.  A jet nozzle comprises a substantially cylindrical outer casing within which is mounted an inner body which is spaced from the outer casing by an annular space through which jet gases may flow, and means for producing a flow of cooling air through at least part of the interior of the inner body comprising an ejector nozzle supplied with high pressure air or gas. The discharge nozzle of a gas turbine jet engine is shown in Fig. 2 and comprises a jet pipe 14 and a fixed inner member 20 which together define an annular passage 21 for the flow of gases therethrough. An axially movable cylindrical casing 15 is disposed around the jet pipe whereby the nozzle may be varied from the convergent form shown in Fig. 2 to convergentdivergent form when the casing 15 is moved downstream. The inner member is supported within the jet pipe by means of hollow struts 22 which communicate with a tubular member 26 disposed within the inner member, the tubular member being connected at its downstream end to the member 20 by a frusto-conical partition 23 which thus divides the interior of the member 20 into a forward compartment 24 and a rearward compartment 25. An outlet member 27 is disposed at the downstream end of the compartment 25 and cooling air supplied through the struts 22 passes into the tubular member 26 and thence into the compartment 25 finally discharging through the outlet 27. The flow of cooling air is assisted by air or gas under pressure passing through line 30 and nozzle 29 into the outlet duct 27. The internal member comprises adjustable parts 31, 32 which are connected by links 34 to an axially movable ring member 35 whereby the shape of the internal member may be varied. In a second embodiment Fig. 3 (not shown) the internal member 20 is not divided into two compartments by a partition, cooling air flowing through the struts 22 into the space within the internal member and discharging through the outlet 27, flow being assisted by the ejector device.

Abstract: 1353288 Fuel injection two-stroke I C engines ATELIERS DE LA MOTOBECANE 4 Oct 1972 [19 Oct 1971] 45782/72 Heading F1B A two-stroke engine has two transfer passages symmetrically disposed with respect to a diametral plane of the cylinder, which plane passes through the centre of the exhaust port and from which passages the flows converge towards a first point on a first generation of the cylinder diametrically opposite to that through the centre of the exhaust port; and an auxiliary transfer passage of smaller section than the normal passages and situated opposite the exhaust port and directing its flow towards a second point substantially opposite the first generatrix, the auxiliary passage containing the head of the fuel injector, the axis of which passes through the second point. The two transfer ports Tn are shaped so as to direct a flow of air, from the crank-case, towards a point P on the cylinder wall opposite the centre of the exhaust port E. Vertically beneath this point is an auxiliary duct Ti which also receives air from the crank-case and which contains a fuel injector I which directs fuel towards a point p which is opposite the point P. Since the air-flows As are established before injection begins, the fuel and the flow of air Ap from the duct Ti are deflected by the air-flows As in a loop towards the top of the combustion chamber. The flows As assist in scavenging the cylinder by pushing the exhaust gases out through the port E. Air reaches the duct Ti via a port L cut through the piston. Air enters the crank-case through two supply ports situated one on either side of, and slightly below the auxiliary duct Ti. In a modification the duct Ti is an inverted U- shape and a single supply port is arranged within the arms of the U. Alternatively both the supply port and the duct Ti may each have a single opening into the cylinder.

Abstract: 1,170,766. Making O-rings; seaming non-metallic sheet material. A. W. CHESTERTON CO. 13 Oct., 1966 [21 Oct., 1965], No. 43883/66. Headings B5A and B5K. [Also in Division F2] A plastics-covered 0-ring is made by deep drawing a circular ring of C-shaped cross-section from a thin disc of plastics material, severing the ring from the rest of the disc, inserting the O- ring within the severed ring, and finally sealing the edges of the severed ring to completely encase the 0-ring. The drawing is effected between a fixed base member 22, having a spring-biased male ring mould 24, and a movable female member 20 having an annular cavity 42 to which a heated pressure fluid can be supplied. In operation, member 20 is lowered to clamp the disc between rings 21 and 29, and rings 41 and 23 after which the disc is heated. Member 20 is then further lowered to draw the disc over the mould 24 and fluid under pressure subsequently supplied to the cavity 42 to apply the sheet tightly over the enlarged head of the mould, the pressure being sufficient to force the mould downwardly against the action of springs 34. The member 20 is finally withdrawn and the formed sheet, supported by the mould 24, removed for the subsequent severing operation. The severing is effected by drawing the sheet, whilst supported on the mould, between a pair of rotating cutting rolls 62 and 64 which engage either side of the drawn ring 15. The wheels are provided with cutting knives 63 and 65 respectively, the wheel 62 being mounted upon a fixed table 60 through a gear 67 and the wheel 64 being mounted upon a lever 61 pivotable to move the wheel into and out of engagement with ring 15. The wheel 64 is driven, in its operative position, by means of a second gear 67 which engages that of wheel 62. The severed ring is subsequently removed from the mould, the 0-ring inserted into it and the whole transferred to a sealing device. The sealing is effected by locating the sheathed 0-ring within a cavity formed between members 72, 68; 71 and 71<SP>1</SP> (see Fig. 17) and welding the overlapping edges of the ring 15 using a heated upper member having an annular pressing ring 75. The edges of the ring 15 are cut in such a way that when they are overlapped and sealed the outer sheath formed by ring 15 is smooth surfaced and perfectly round (see Figs. 18 and 19, not shown). Reference has been directed by the Comptroller to Specification 1,103,979.

Abstract: 1,033,845. Endless conveyers. CROSS CO. Nov. 18, 1964 [Feb. 6, 1964], No. 47015/64. Heading B8A. A pallet 16 is transferred from a conveyer 10 to a work station 14, from which it is subsequently conveyed away in a direction perpendicular to the conveyer 10 by a conveyer 12, by a transfer mechanism which is actuated by the conveyer 10 and which moves the pallet at a progressively reduced rate of speed and accurately positions the pallet in a predetermined position in the work station. The conveyer 10 comprises a driven endless chain 36 provided with dogs 34 which push the pallet over idler rollers 18, 20 between guides 30, 32. The transfer device comprises cams 148 and pivoted pusher dogs 124, with counterweights 128, mounted on arms 112 pivoted to a fixed bracket 116, the arrangement being such that the counterweights normally cause the arms 112 to rest against a stop 138, Fig. 4 (not shown). In operation, a pallet 16 is pushed part way into the station 14 by a dog 34 and as the rear edge of the pallet passes over the dogs 124, the weights 128 raise the noses 132 of the dogs to engage the rear edge of the pallet. As the dog 34 disengages from the pallet on passing around the chain sprocket 40, the cams 148 are engaged by rollers 156 on the conveyer chain 36 which rock the arms 112 forwardly to the fully advanced position, Fig. 5. The contours 160 of the cams 148 are such that forward movement of the arms 112 and of the pallet 16 occurs at a gradually diminishing rate and as the rollers 156 begin to move around the chain sprocket 40, they move under the cams and finally release them. The contours of the cams are also arranged so that the rollers 156 remain in contact with the cams for an interval after the dogs 124 reach their forwardmost positions to hold the pallet positioned properly in the work station regardless of any rebound that may tend to occur. The arms 112 are returned to their initial positions against the stop 138 either under the action of gravity, or by co-operation of one of the dogs 34 with an abutment 166 on a bracket 168 secured to the arms, or by means of a spring device, Figs. 6, 7 (not shown).
