Filed: 1975-04-01
Abstract: 1466171 Aerials STANDARD TELEPHONES & CABLES Ltd 1 April 1975 [9 April 1974] 15652/74 Heading H4A A coaxial radiating cable comprises a central conductor 11, a dielectric layer 12 and a leaky outer conductor 13 having a layer or coating of conducting material which has a conductivity less than that of the outer conductor 13. The layer 14 may be a paint containing carbon or metal (e.g. aluminium, zinc, nickel, iron or steel) or it may be a sheath of polyethylene or pvc containing carbon, Fig. 2 (not shown). When the outer conductor is coated with conductive paint, it may be protected by a low loss sheath 15, e.g. of polythene. The outer conductor is made "leaky" by longitudinal slot 13a. The cable is to be used in radio communication systems in underground tunnels &c. and is said to reduce the "standing wave pattern" caused by interference between waves in the primary cable mode and in a secondary mode caused by the interaction of the electric currents in the outer surface of the outer conductor with the ground plane outside the cable.

Title: Multi-aspect light signal for u.j.p. railways
IPC: B61L5/18
Filed: 1954-05-28
Abstract: 762,407. Railway light signal. STANDARD TELEPHONES & CABLES, Ltd. May 28, 1954 [June 3, 1953], No. 15835/54. Class 105. A relay at a multi-aspect railway light signal is connected in the operating circuit for a signal aspect and is responsive to current flowing in the operating circuit to complete a lighting circuit, energizable by current flowing in the operating circuit and including a lamp or lamps appropriate to the aspect. In the embodiment described a green lamp is used in two aspects viz. a green and a green-yellow aspect, and a relay appropriate to the green-yellow aspect both connects the green and yellow lamps to the lighting circuit of the green-yellow aspect and disconnects the green lamp from the lighting circuit of the green aspect. The simultaneous operation of the two aspect relays, such as when contact between the leads from the control point occurs, produces a distinctive e.g. a yellow only, signal. As shown, contacts m<1>, m2 when closed connect the power to transformers T1, T2 via the primary winding e.g. of a supervisory transformer T3. On the closure of contact sa, e.g. manually, relay A whose winding is connected across the secondary winding of transformer T1 operates to close contact a1 to complete a lighting circuit via back contact b1, the winding of a relay J and the green lamp G to give the green aspect. On closure of contact sb, relay B, energized from the secondary winding of transformer T2, operates to close its front contact b1 to complete a circuit including the back contact a1, winding of relay J and the green and yellow lamps G, Y in series, the output of the transformer T2 being double that of transformer T1 so that the green lamp will be as bright as when used alone in the green aspect, and being taken from a mid-point tapping on the primary winding of relay T3 so that the output of the transformer T3 is the same whether contact sa or sb is closed. A relay C whose winding is connected across the secondary winding of transformer T3 responds only to the current fed to the lamps and contacts on this relay may be used for supervisory purposes, or to break the circuit of a normally lit red lamp. When the two relays A and B operate together, lamp G is cut out of circuit at contacts a1, b1 and the current from transformer T2 is partially opposed by the current from the transformer TI so that the yellow lamp Y is lit at its normal brilliance. Contacts jl, j2 of relay J may be included in a pair of train control circuits each including a coil t1 or t2, one of which also including a back contact b2 of relay B. A coil on a vehicle passing over the coils t1, t2 in turn is influenced thereby and can be used to effect an indication in the vehicle corresponding to the signal aspect displayed. The relay J may be dispensed with and contacts j1, j2 replaced by contacts of relay A.

Title: Improvements in or relating to sheet retarding mechanisms for use with sheet feeding mechanisms
IPC: B65H9/14
Filed: 1927-06-14
Abstract: 288,456. American Type Founders Co., (Assignees of Kelly, W. M.). April 15, 1927, [Convention date]. Sheet-registering devices; feed-tables; sheet carriers and guides.-Sheets are retarded near the front stops 61 of printing-presses by means of reciprocating fingers 55 notched at 55<a> to engage the front edges of the sheets as these leave the control of adjustable upper sheet-conveying tapes 11. The fingers reciprocate in longitudinal dovetailed recesses in slides 54 which are each vertically adjustable in brackets 35 by the operation of a screw 68, which can be effected while the feed is in operation. The brackets 35 can be laterally adjusted on a bar 7, forming part of a pivoted frames 5 - - 8 which can be pivoted about a shaft 9 from which the feeding-tapes 11, 12 are driven, so as to permit of access to cylinder 4. The feed-table 3 with its extension 64 and other associated parts can be pivoted about pivots 3<a> for a similar purpose. For dealing with sheets of different lengths, the upper feedtapes 11 are passed over adjustable pulleys 18, 19 which can be set to allow the positive fast drive of the sheets to be cut off at the desired distance from the stops 61. While the fingers 55 are retarding the sheets, they are engaged between guides or throats formed of adjustable upper guides 58 provided with bifurcated lower prongs 60, and curved guide fingers 64 mounted on a cross bar 65 secured beneath the feed-board. The fingers 55 are moved towards the stops 61 while the sheets are being registered to pass through recesses in the stops, the fingers being operated by links 71, adjustably mounted levers 72, and cams on the shaft 9. To the links 71 are secured adjustable brushes 79 which are set to engage the rear edges of the sheets and press them against the front stops 61.

Title: Improvements in and relating to aircraft navigation apparatus
IPC: G01C21/20
Filed: 1944-01-30
Abstract: 589,338. Course steering apparatus for aircraft. MAY, W. J. Jan. 30, 1944, No. 16081/43. [Class 97 (ii)] A device to be used on course-steering and bombsighting apparatus so that wind velocity and direction may be ascertained without altering course and compensations may be made for height of ground above sea level and variations in altitude of flight. The device comprising a supplementary foresight, 43a carried on a rearward extension 42 of the track bar 34 and a disc 51 graduated in compass degrees and inscribed with concentric. wind velocity circles may be added to the apparatus described in Specifications 145,810, [Class 97 (ii)], and 542,792, [Group XIX]. The supplementary foresight 43a which allows sights to be taken on an object away from which the aircraft is travelling and the foresight 35 at the point of intersection of the wind bar 32 and the track bar 34 are equidistant from the guide 36 and mutually adjustable by the knob 50. In use, the navigator pivotally connects the wind bar 32 to the track bar 34 so that the foresight 35 will not move relatively to the track bar but will rotate over the disc 51 as the length of the extension bar 42 is altered. A ground object directly beneath the aircraft is selected and at the end of a predetermined period of time the selected object is observed through the sights 39 and 43a. Adjustment of the sight 43a results in relative movement of the sight 35 and consequently the wind bar 32 to indicate the wind direction and velocity. The dials 15 and 18 can now be set for the new wind direction and velocity. In order that the apparatus itself will not impede correct sighting, an auxiliary back-sight 39c is used with a laterally placed supplementary fore-sight 43a and when vertical sights are required with the depending fore-sight 39a. Since the time over which an observation should be made is affected by altitude, the rack 38a with altitude graduations 38b allows the back-sight 39c to be adjusted to correspond with altitude readings from the altimeter and the graduations 38b used in conjunction with an adjustable index corrects for time lag in the dropping of bombs. Further corrections for the height above sea level of the ground over which the navigator is flying and in the observation of objects dropped into the sea or on land are made by use of the timing device shown in Fig. 6 which may be set for altitude or arranged to compensate for height of ground above-sea level and shows by the intersection of hair lines 74, 80 with the time graduations 75, 79 the periods of time for making observations on fixed ground and sea objects and objects dropped into the sea.

Abstract: 1,161,729. Motor vehicle drive lines; preventing axle hop. ADAM OPEL A.G. 4 April, 1968 [26 April, 1967], No. 16250/68. Heading B7H. [Also in Division F2] In a motor vehicle having an engine connected through a drive line to a rigid rear axle suspended by springs and dampers, a component in the drive line is of such torsional softness or stiffness that the respective natural frequencies of torsional vibration in the drive line and of rise and fall of the rear axle are separated to such an extent as to avoid mutual stimulation between the two systems whereby extreme torque fluctuations in the drive line do not produce a negative overall torque considered in relation to that supplied by the engine and axle hop under accelerating and braking conditions is avoided. Torsional softness may be provided in the drive line by a flexible coupling, Fig. 8, fitted between the gear-box output shaft 22 and the propeller shaft 16. The coupling comprises a rubber element 10 of low Shore hardness bonded between conical flanges 25, 26. Stop pins 27 limit maximum twisting of the coupling to 30-40 degrees in a forward direction and 80-90 degrees in reverse. A centring device 28 locates the two shafts and the coupling also accommodates misalignment of the shaft axes to replace the usual universal joint. Torsional softness may alternatively be provided by employing a torsionally flexible propeller shaft, Fig. 13, comprising bifurcated heads 35, 36 connected to tubes 37, 38 having bonded thereon rubber rings 39, 40, 41, 42 which are pressed into an outer tube 43. Twisting of the shaft is limited by pins 48, 49 mounted in the heads 35, 36 for co-operation with slots 46, 47 in lead-in cones 44, 45 fitted on the outer tube 43 to facilitate insertion of the rubber rings. Torsional stiffness may be provided in the drive line by increasing the torsional stiffness of the half shafts in the rear axle. In Fig. 11 a reinforcing tube 33 having at each end a splined connection is fitted to the half shaft 30. In another embodiment large diameter half shafts having a torsional stiffness twice as great as is conventional are fitted. Tubular half shafts may be employed in order to save weight.
