Title: Three dimensional radar system with integrated ppi presentation
IPC: G01S7/20
Filed: 1976-10-28
Abstract: 1509166 Radar INTERNATIONAL STANDARD ELECTRIC CORP 28 Oct 1976 44832/76 Heading H4D In a 3-dimensional pulse radar, providing a PPI display 131 and a range-height display 132, a pencil beam formed by a vertical array 101 and a vertical reflector 101a is scanned electronically in elevation and mechanically in azimuth, the elevation scan being a series of within pulse incremental scans with range range determining lapses between successive pulses. The maximum detectable range for each incremental scan, i.e. the lapse before the next transmitted pulse, decreases with increasing elevation such that the volume of space surveilled has an approximate constant height. The within pulse scan is incremented, e.g. for a pulse width of 27 Á sec there are 9 frequency steps of 3 Á sec each giving 9 sub-incremental scans per pulse and the beam width and out-incremental scan rate is such that a target is illuminated by about three successive beams whereby by successive 3 Á sec delaying of returns (121-129) and suitable addition (130) of the delayed returns, target responses are emphasized and noise is cancelled.

Patent GB-459266-A (GB)
Abstract: 459,266. Postmarking and like machines. HASLER AKT. - GES.WERKE FUR TELEPHONIE & PRAZISIONS - MECHANIK, 50, Schwarztorstrasse, Berne, Switzerland. May 25, 1936, No. 14766. Convention date, June 21,1935. [Class 100 (ii)] Stopping, starting, and like arrangements.-In a postmarking or like machine of the kind in which a rotatable marking- cylinder is driven in conjunction with an endless conveyer for articles to be franked and is arranged to be automatically stopped at the completion of each rotation, a feeler is arranged above the conveyer and is adapted to be lowered either to press an article on to the conveyer and then release the cylinder, or to drop below the conveyer if no article is present and so prevent the starting of the machine. The convever consists of belts 8 mounted below a feed-table 1 on which is supported a manually-rotatable shaft 14. The shaft 14 carries a cam 18 engaging a finger 17 loosely mounted on the shaft and adapted, when rocked by the cam, to depress a plate 20 pivoted on a rod 21 and normally held in raised position by springs 23. The plate carries a shaft 24 on which a lever 25 is pivoted. The lower arm of the lever extends through a slot in the plate and is forked to engage a pin 27 on a pivoted plate 28, a spring tending to depress the and plate 28 but being normally prevented by the engagement of the cam 18 by a pin on the lever. The plate 28 detachably carries a member 30 slotted so as to indicate the position at which the frank will be applied. Pivoted on the shaft 14 are pairs of levers 31, 32 carrying respectively rollers 33 and flat springs 34 which act to hold the articles on the conveyer ; the levers are normally held in raised position against the action of springs by the plate 20 and shaft 24. In use, the article is placed on the conveyer, and the shaft 14 is rocked, thus causing the finger 17 to depress the plate 20 and permit the rollers 33 and springs 34 to grip the article ; the plate 28 also descends and rests on the article. Rocking of the cam 18 permits a spring-pressed lever 37 secured to the rod 21 to fall so that the finger 17 engages a slot therein and is prevented from return. When the article is properly gripped, a lever 13, Fig. 4, which is carried by the shaft 14 and which has moved idly relatively to a link 11, rocks the link and releases a clutch-operating pawl 3 to set the cylinder 2 and conveyer into operation. Near the end of the rotation of the cylinder a cam thereon rocks a lever 39 secured to the rod 21 and causes the lever 37 to release the finger 17 so that the parts can be reset in normal position by spring action. The cylinder then resets the pawl 3 in position to disengage the clutch. If the shaft 14 is rocked and no article is in position on the conveyer, the plate 28 falls between the conveyer belts and an offset on the end of the lever 25 engages a notch 19 in the end of the finger 17 to prevent the shaft from being rocked sufficiently far to release the pawl 3.

Abstract: 1434529 Valves GENERAL MOTORS CORP 6 Sept 1973 [6 Oct 1972] 46150/72 Addition to 1126157 Heading F2V [Also in Division F1] I.C. engine air intake control system in which a valve 12 actuated by a vacuum motor 7 in response to engine-intake vacuum is arranged to control an admixture of heated air with ambient air in the engine intake passage 5, the action of the vacuum being modified by a thermo responsive air bleed valve which bleeds air into the motor at a rate which increases with intake air temperature, and has interposed in the conduit 17, 21 between the motor 7 and the source of engine intake vacuum, a thermoresponsive non-return valve which is closed when the engine is cold, but permits fluid flow from the vacuum motor to the source but not in the opposite direction and opens when the engine has warmed up to permit flow in either direction. Vacuum motor 7 contains a spring biased diaphragm 9 connected to valves 11 and 12, the diaphragm being moved against the spring by the depression in the intake duct acting through conduits 21 and 17. Temperature sensor 19 includes an air bleed valve 32 actuated by a bimetal strip 33. Valve 32 co-operates with a valve seat 31 formed in a plate 27 which divides a plastics housing 25, 26 into an upper chamber which is in open communication with the interior of the air cleaner and a lower chamber 28 connected to conduits 17 and 21. An adjustable screw 39 allows the position of bimetal strip 33 to be set so that valve 32 is closed when the engine is cold. A second valve 45 consists of a guide stem 46 and a head 44 which engages a bimetal strip 43 which is isolated from the air in the air cleaner 1 and is heated slowly as the plastics case 26 is heated by conduction from the engine during the warming-up period. Operation.-When the temperature of the air in the air cleaner is low, valve 32 is closed and intake manifold vacuum is applied to vacuum motor 7 which opens valve member 12 so that the engine receives heated air from pipe 14. If, while the engine is cold, it is accelerated suddenly, the vacuum in the manifold will decrease sharply, and this would result in valve member 12 closing so that the engine received only cold air. This is prevented by valve member 45 being held on to its seat by the vacuum in conduit 17, until the slow heating of bimetal strip 43 causes the valve to open.

Abstract: 1,057,489. Aerials. MARCONI CO. Ltd. Oct. 31, 1963 [Dec. 12, 1962], No. 47010/62. Heading H4A. An aerial consists of two conical members 1, 2 having a common cone axis and spaced apart along the axis with their bases away from one another, a partition member 3 in a plane at right angles to the axis and extending across the space between the members 1, 2, means such as plates 4 associated with one of the members for twisting the plane of polarization of transmitted energy through 90 degrees, and feeder means 6, 7 connected to the conical members whereby when the feeder means is energized waves with mutually perpendicular planes of polarization are transmitted from the aerial, waves of one plane of polarization from between one conical member and the partition 3 and waves of a perpendicular plane of polarization from between the other member and the partition. The phase centres of the mutually perpendicular polarizations are at different heights and by careful choice of dimensions it is possible to make the first zero of the vertically polarized radiation pattern coincide with the second null of the horizontally polarized radiation pattern at a given angle of elevation for example 30 degrees. For elevation coverage of 0-30 degrees the height of the phase centres are #/2 and # for vertical polarization and horizontal polarization respectively. The Figure shows a half sectional view of an embodiment of the aerial which operates against a ground plane (Fig. 1, not shown) to which the lower conical member is connected and in which the plates or vanes 4 are formed by bent diamondshaped plates (Figs. 4-6, not shown) and which are so positioned that they each extend at an angle to radial lines passing through the centre of the cone 2. The feeder is a coaxial feeder having its outer conductor 6 connected to the lower conical member 1 and its inner 7 to the upper member 2. In a further embodiment (Fig. 9, not shown) the feeder has an intermediate tubular conductor between the conductors 6 and 7 and connected to the partition member 3 so that an adjustable power divider may be used to apportion power between the two feeders.

Abstract: 1502008 Automatically operating dispensing valves for pressurized dispensers T H PETTERSON 20 Nov 1975 [2 Dec 1974 (3)] 47745/75 Heading F1R A pressurized aerosol dispensing container is intermittently discharged by means of a valve actuated by the container pressure developed in an accumulator space connected to the container through a flow control body which permits only very slow flow therethrough and partly volatilizes the aerosol liquid whereby the pressure and liquid quantity in the accummulator builds up slowly until the pressure opens the valve and allows discharge of the gas and liquid in the accummulator chamber. The discharge means may form part of the container (e.g. as shown in Fig.7), or may be partly seperable therefrom (e.g. as in Fig.2 (not shown)) or comprise an attachment for mounting on a valved container, e.g. Fig.11 (not shown). As shown in Fig.7 the accummulator chamber 10a receives liquid and gaseous fluid from the container dip tube 7a via the flow control body 5a which comprises porous material, flow through which is further restricted by an orifice plate 38. The chamber 10a connects with a valve chamber 17a via a dip tube 11a and the pressure acts on a snap valve diaphragm 23a which engages a valve seat 19a to control discharge passage 24a. The valve is shown held closed by the adjustment stop screw 36 which by axial adjustment controls the movement of the diaphragm 23a and hence the rate of operation and the quantity discharged. The device shown discharges gaseous fluid followed by liquid and again gaseous fluid. A gas tap 40 increases the flow of gas to the accummulator. Numerous embodiments are described which include alternative diaphragm stops; diaphragm valve constructions, e.g. Figs. 14, 19, 31 (not shown); means for controlling the rate of flow through the flow control body e.g. Figs. 17, 26 (not shown);labyrinth and lilse control bodies e.g. Figs. 28, 29 (not shown); and means for obtaining direct discharge from the container e.g. Fig.9 (not shown).
