Title: Improvements in or relating to radar systems
IPC: G01S7/28
Filed: 1961-10-09
Abstract: 946,978. Automatic frequency control systems; radio receiving systems; pulse radar. COMPAGNIE GENERALE DE TELEGRAPHIC SANS FIL. Oct. 9, 1961 [Oct. 10, 1960], No. 36180/61. Headings H3A, H4D and H4L. In a pulse radar system interference is reduced by employing two receiver channels, one of which is connected to a directional aerial and the other to another aerial, the channel outputs are combined to give sum and difference signals, and first and second " error " signals are derived from the sum and difference signals to control relative phase and gain in the receiver channels so as to reduce the error signals to zero. In one embodiment, Fig. 1, the received interference output of directional aerial 1 is fed via controlled attenuator 21 and controlled phase shifter 22 to a device 23 which has an additional input from an omni-directional aerial 2 and which produces sum and difference signals s sin (wt+a), d sin (wt+d) respectively at terminals 5, 6; terminal 6 is connected to a display or other utilization device 15. A known detector 29 produces an output signal proportional to sd cos (d - a) and a similar detector 30 produces an output signal, because of the insertion of 90 degrees phase shifter 31, proportional to sd sin (d - a). Unit 32 produces output amplitudes proportional to sd and d - a to control attenuator 21 and phase shifter 22 respectively such that the difference signal output from unit 24 tends to zero. The frequency response of unit 32 is limited so that it will not follow fluctuations due to the reception of radar echoes; but that frequency response must be wide enough to follow fluctuations due to the rotation of aerial 1. To allow for a higher level of interference from aerial 2 than from aerial 1, each aerial output channel may incorporate controlled attenuation and phase shift, Fig. 2 (not shown). If a radar and an interference source operate in close proximity, e.g. on the same vehicle, the controlled attenuator and phase shifter are in the omni-directional aerial channel, Fig. 3 (not shown). It is stated that target detection will be difficult if both target and interference source lie in the same direction, and that this difficulty can be avoided by replacing the omni-directional aerial by a directional aerial the polar diagram of which has a pronounced " dip " in the direction of the main lobe of the main aerial and by rotating it in synchronism with the main aerial, Figs. 4-8 (none shown).

Title: Ship stabilising systems
IPC: B63B39/06
Filed: 1974-08-20
Abstract: 1512956 Stabilizing fins SPERRY RAND LTD 6 Aug 1975 [20 Aug 1974] 36535/74 Heading B7M A ship's stabilizing fin 3 is mounted on a shaft 14 tiltable about its longitudinal axis by a pair of actuators 38, Fig, 4, the end of shaft 14 being located within a housing 15 which is rotatably mounted in bearings 58, 59, Fig. 6, to effect movement of the fin between stowed and operative positions, the bearings being large enough to permit access therethrough to the shaft 14. In the stowed position the fin is located in a box 4, the outer wall 5 of which is flush with the ship's hull 1 and has an opening to allow passage of the fin therethrough and installation of the housing 15, the larger part of the opening being substantially closed in both positions of the fin by plates 16, (20) Fig. 3 (not shown). The actuators 38 are doubleacting hydraulic actuators whose pistons act on diametrically opposite portions of a ring 47 clamped on shaft 14, the cylinders being pivotally mounted in an oil-filled chamber 36 in housing 15. Movement of the fin between operative and stowed positions is effected by a second pair of double acting hydraulic actuators (91) Fig. 2 (not shown) whose pistons 93, Fig. 6, are connected through shear bolts 95 to diametrically opposed points on an extension 103 of bearing member 69 secured to the top of housing 15, a locking shear pin (99) Fig. 8 (not shown) being engageable in one of a pair of apertures 102 in the operative and stowed positions of the fin. The pin (99) is associated with a control which allows energisation of actuators (91) only when the pin is retracted. Limit switches (118) Fig. 9 (not shown) linked to actuators (91) ensure precise alignment of apertures 102 with pin (99) when the fin is being positioned. The shear bolts 95. and pin (99) prevent damage to the fin should it strike an object when operative. The fin has a trailing flap 18 controlled by an actuator 17 in known manner. The tilt angle of the fin may be signalled to a remote position via a transducer on the end of the shaft 14, and also a mechanical linkage may give an indication of tilt angle by means of a needle and scale mounted on the top of housing 15, Figs. 10-12 (not shown). The needle (128) is arranged to move a rod (133) as it approaches the desired maximum, angle of tilt to cut off the supply of hydraulic fluid to the tilt means 38. A feedback signal of the lift force acting on the fin is obtained by transducers (54) Fig. 5 (not shown) which are reresponsive to relative movement between the end of shaft 14 and a bracket 52 attached to a cantilever shaft 49 produced by bending stresses acting on fin 3.

Abstract: A polyolefin film which may take the form of a coating on paper has adhered thereto a heat-sealable layer of a polyolefin with a lower melting point than that of the polyolefin film.  The film is prepared by applying the layer to or forming the layer on at least one surface of the film e.g. by the application thereto of the lower melting point polyolefin as a solution in a solvent, an aqueous dispersion which is thereafter heated to provide a coating of between 0,2 and 4,0 gm. per square metre, a hot melt the temperature of which may be greater than its gelation temperature, or as a fine dry powder which is thereafter fused. The layer of lower melting point polyolefin may be applied to one surface of the film and thereafter compression rolled.  The compression rolling may be sufficient to reduce the thickness of the film to between one-half and one-tenth of its original thickness.  The polyolefins may be polymers or copolymers of a -olefins having between 2 and 10 carbon atoms e.g. ethylene or propylene, degraded polyethylene or oxidized degraded polyethylene, and may contain a thermosetting resin such as phenol-formaldehyde. The coatings may be applied, for example, by dipping, kiss-roll, air knife or spreader-bar.  The surface of the low melting point polyolefin which remains exposed may be subjected to a corona discharge or flame treatment to improve the surface for printing, or subsequent coating with photographic gelatin emulsions or emulsions of metal oxides in the production of magnetic tapes.
