Title: Control system for a vehicle hydraulic suspension arrangement
IPC: B60G17/033
Filed: 1980-12-29
Abstract: A vehicle has a body 10 and a plurality of wheels 11 having respective hydraulic suspension units 1L to 5L hydraulic suspension units 1L to 5L and 1R to 5R which are-arranged in groups 13, 14, 15, 16 having respective valves 28 for controlling fluid flow between parts of the suspensions. An ultrasonic range finder unit 40 on the front of the vehicle body provides signals which cause the valves 28 of the groups 13, 14, 15 to be shut as the wheels 11 in those groups move upwards relative to the body 10, and to be opened as those wheels 11 move relatively downwardly, thereby increasing the ground clearance at the front of the vehicle. <IMAGE>

Title: A cartridge-firing cannon, for example for an aircraft
IPC: F41A9/54
Filed: 1981-05-08
Abstract: An aircraft cannon (Figure 1) has a body (1A) and barrel (6) mounted by damping mechanism (3) on aircraft structure (5). The cartridge feed of the cannon includes a rigid cartridge guide portion (16) mounted on the aircraft structure. The portion (16) feeds a belt and cartridges to the body (1A) by way of a motion-compensating cartridge guide (20) which is connected articulatedly at its ends respectively to the body (1A) and the portion (16). The latter is fixed at right angles to the barrel axis x. The arrangement permits the portion (16) to be a simple rigid rectangular tube mounted directly in the aircraft structure, whilst the guide (20), by virtue of its articulated end connections, accommodates recoil and counter-recoil movements of the barrel and cannon body. <IMAGE>
Patent GB-2105827-A (GB)
Title: Anti-vibration mountings
Inventor: STANGROOM JAMES EDWARD
IPC: B64D7/04
Filed: 1981-08-13
Abstract: An anti-vibration mounting for protecting structure against impulses generated by a reciprocating mechanism, where the mount is for use with automatic guns installed in aircraft, comprises a carriage (12) guiding a gun (13) on a pair of parallel rods (11) by means of swinging telescopic arms (14) each containing a compression spring (not shown) and by an axially-acting compression spring (15, 16). In operation, ratchets (20) engage flange (18) on spring casing (16) in a position where it exerts a force on the carriage (12). As the carriage (12) recoils from the position at (21) where the gun is fixed, the spring (15) acts as a positive rate spring, while the springs in arms (14) act as negative rate springs, the strengths of the springs being such that they combine to operate as a zero-rate spring. At the end of a firing sequence, the ratchets (20) are disengaged and the recoil is resisted only by the springs in arms (14) so that the carriage (12) moves beyond its operational maximum recoil position and ratchets (19) engage a further flange (17) on the carriage (12). <IMAGE>

Title: A radar for the detection and discrimination of tracked vehicles
Inventor: VOLES ROGER
IPC: G01S7/41
Filed: 1982-03-02
Abstract: A radar apparatus (Figure 4a) is arranged to identify a variation in the amplitude of received radiation as a function of radar viewing angle, indicative of a track of a tracked vehicle, by correlating the variation with a reference waveform (L1), indicative of a track. A sequence (S) of electrical signals, representing the amplitudes of returns of successive viewing angles is loaded into two shift registers (SR1, SR2). The storage locations in each shift register are weighted by respective amounts corresponding to the reference waveform (L1) in the case of SR1, and the complement (L2) of that waveform in the case of SR2. The signals are cycled through the shift register once and the weighted outputs A, B compared. When A is greater than B a target is declared. The amplitude variation can be correlated with a number of different reference waveforms (Figure 4b).

Title: Signal suppression
Inventor: AINGER ANDREW WILLIAM SIMPSON
IPC: H01P3/06
Filed: 1982-06-22

Title: Heating apparatus
Inventor: REED GEOFFREY RONALD
IPC: B22D41/015
Filed: 1982-07-30
Abstract: Apparatus for heating hollow objects, in particular for preheating metal-pouring ladies, comprises a low thermal mass plug body (90) to be inserted into the object to be heated and means for directing a hot gas flow, conveniently produced by a burner (78) in the bottom or inner region of the plug, through a relatively narrow gas path that is either formed by a gap between the body and the interior wall of the object or is in a conduit formed between the body and a thin-walled surrounding shroud (92) on the body. The hot gas flow is thereby used more efficiently than if it were simply allowed to fill the interior of the body to be heated. Efficient heat transfer is obtained from the flow of gas in contact with or close to the interior wall of the object, and in the latter case the flow is enclosed by a shroud arranged to reach the hot gas temperature quickly and radiate heat to the inner wall of the object. <IMAGE>

Title: A process for manufacturing granular compound fertilizers
Inventor: KINNOU BUNJI
IPC: C05B7/00
Filed: 1983-02-18
Abstract: In the process, phosphoric acid, sulfuric acid or nitric acid or a mixture thereof is reacted with ammonia gas in a tubular reactor (1), then in a mixing tank (2); the reaction solution is concentrated in tank (2) by evaporation of water to obtain a high temperature slurry having a liquid content of 40-90% by volume, and the high temperature slurry is then injected by spray means (14) into a granulation zone of a spouted bed granulation apparatus (15) or fluidized granulation apparatus to cause the thus-sprayed slurry to stick to priming particles fed separately into the apparatus which float in the granulation zone, thereby forming enlarged granules. The granules contain two or more of the agronomically effective elements N, P and K in proportions adjustable- if desired-by solid, liquid or aqueous fertilizers or diluents which are added to the slurry before granulation. <IMAGE>

Patent GB-2173973-A (GB)
Title: Telephone switching systems
Inventor: BARRY DOUGLAS WILLIAM
IPC: H04M3/42
Filed: 1985-04-15
Abstract: A telephone switching system provides dial tone to connected telephones when they go off-hook. Digits dialled are interpreted as a wanted external number. In this way the system resembles a direct exchange line in operation. By signalling a switchook flash instead of a dialled digit, the telephone can request special features such as internal calls or abbreviated dialling, if the switchook flash is signalled during an external call, the special features could include enquiry and transfer, or multi-party conference connections. The system operation is convenient when most calls are outgoing rather than internal, and also for casual users, who do not need to be aware that a switching system is in use. A distinctive dial tone, given in response to the switchook flash, can also be given to warn telephone users if the external line is unavailable. <IMAGE>
