Title: Untrasonic examination
IPC: G01N29/04
Filed: 1975-02-26
Abstract: 1503532 Ultrasonic scanning devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Feb 1975 [1 March 1974] 8022/75 Heading G1G A cross-section of a body is scanned ultrasonically by use of a row LER of n rectilinear phased arrays of transmit/receive transducers. The arrays are arranged end-to-end and are actuated in turn as transmitters. Each array comprises m transducer elements, energized with appropriate phase delays for transmitting a pulsed beam fi of ultrasonic energy in a set of discrete angular directions sequentially. El-Ei-En represent the transmission points (considered to be the array centres). Following transmission of a pulse in a given direction, a group of m transducers are selected and operated as receivers for echoes incident normally on the array by combining their outputs in-phase. The group of m selected (adjacent) transducers is shifted, by appropriate signal gating, in steps of one transducer at a time at a rate dependent on the ultrasonic transmission direction to provide scanning of the receiving point Rx (the group centre) along the row LER away from the transmission point, thereby scanning the reflection points SS in depth (slant range). The combined output of the group of m receivers modulates the brightness of a CRT whose X and Y deflections are controlled in dependence on the ultrasonic beam direction and transmission point Ei so as to display a cross-section of the scanned body, e.g. for medical diagnosis. Apparatus for effecting the ultrasonic scanning, including a shift register and gating circuits, is described Fig. 2 (not shown).

Patent GB-804072-A (GB)
Title: Process for the purification of polyethylene
IPC: C08F6/02
Filed: 1955-03-22
Abstract: Polyethylene, prepared in the presence of a liquid organic medium and a catalyst comprising an organo-metallic compound and a salt of a transition metal of Groups IV, V and VI of the Periodic System, is purified, by removing a major proportion of the liquid medium which is adherent to the polymer and by reducing the ash content, by treatment with steam in a single- or multi-stage operation.  The steam-treatment may be at normal or reduced pressures, e.g. 0.2 atmospheres, at temperatures between 50 DEG  and 100 DEG  C.  The bulk of the liquid medium may be mechanically separated from the polymer which may then be washed with a dilute alkaline solution, e.g. sodium or potassium hydroxide or an alkali-metal carbonate, or an aqueous mineral acid, e.g. nitric hydrochloric or sulphuric acids, preferably at an elevated temperature with wetting agents such as fatty alcohol sulphonates or alkyl aryl sulphonate and the polymer is then treated with steam, separated and dried.  In a modification the acid and steam treatments may be simultaneous and continuous, in a zone provided with a stirrer, at about 100 DEG  C. and a pressure to form a distillate.  The acid may be introduced at once or at intervals, to the treatment zone and the aqueous phase of the distillate combined with that from the polymer and recycled. Alternatively the steam may be mixed with acid-forming gases such as hydrogen chloride, sulphur trioxide and nitric oxides and passed for example through a vertical tube of polymer, or the polymers may be sprayed with acid during steam treatment.  The polymer is finally washed to yield a granular product of reduced ash content.  In examples, polyethylenes prepared in naphtha media of C7-C11 aliphatic hydrocarbons, in the presence of a mixture of titanium tetrachloride and aluminium diethyl monochloride are treated.

Abstract: 1501833 Purifying IC engine exhaust gas; controlling IC engines NISSAN MOTOR CO Ltd 4 March 1976 [6 March 1975 10 March 1975] 08658/76 Heading F1B [Also in Divisions B1 and F4] An I.C. engine exhaust purifying system comprises an afterburner and/or catalytic reactor 28 and a sensor 32 mounted downstream of the afterburner for emitting a signal representing the concentration of a given constituent in the exhaust gases from the device 28, which signal controls means regulating the composition of the exhaust gases passing to the device. The control means may provide a predetermined fuel air ratio to the engine 10 by means of an electric or electromagnetic valve 22 in the fuel supply to the mixture supply means 18 which is electronically controlled by a unit 24 connected to the sensor 32. In a modification, Figs. 4 to 6, (not shown), the electronically controlled valve may be situated in an air conduit 46 between an air filter 16 and the exhaust gas duct 26 upstream of the afterburner, to supply air into the exhaust system. A similar but supplementary air supply 40 comprising an air pump 44 in the conduit 46 may be provided which is controlled in response to the operation of the engine by means (not shown), acting to control a valve 48 in the conduit 46, and a check-valve 42 is mounted therein to prevent reflux of exhaust gases thereinto. A second, supplementary air supply means provides air from the air pump 44 to the fuel air duct downstream of the mixture supply means 18 through a check-valved conduit 49 when the degree of vacuum created in the fuel-air intake system is above a predetermined level. An exhaust gas recirculating system 54 having a valve 58 also reponsive to the degree of intake vacuum recycles some exhaust gases into the intake system from a point downstream of the afterburners. The ratio of air-fuel supplied to the engine is additionally controlled in accordance with engine operation and/or ambient conditions so as to maintain optimum exhaust gas temperatures for burning. Means to detect such factors comprise sensors responsive to rotation of the throttle valve, accelerator position, engine speed, coolant temperature, exhaust gas temperature, ambient air temperature, engine intake vacuum, intake air-flow, and fuel flow.

Title: Electric remote aiming system for aiming fire-arms and the like
IPC: F41G5/06
Filed: 1937-03-24
Abstract: 482,325. Electric control systems ; gun-control systems. LORFEUVRE, M. March 24, 1937, No. 8673. Convention date, March 26, 1936. [Class 40 (i)] [Also in Group XXI] In a control system, more particularly for aiming guns from a sighting telescope, the control and controlled members operate variable impedances, e.g. condensers, connected in a bridge circuit which is automatically rebalanced by an electric, hydraulic or other servomotor when the balance is disturbed. As shown, condensers 21, 25 controlled respectively by the sighting telescope 1 and the gun 10 are connected in a bridge circuit comprising the condensers and the tapped secondary 27, 28 of the transformer 30, an amplifier 70 being connected across the diagonal points 26, 29. The amplifier 70 controls a pair of electric discharge valves 35, 36 oppositely phase biassed by the secondaries 33, 34 and adapted to control the operating solenoids 50, 53 of a,servomotor for controlling the gun. When the telescope is moved the capacity of the condenser 21 is varied and the unbalance causes a P.D. across resistance 74 to render one of the valves 35, 36 operative and thereby cause the servomotor to operate the gun until balance is restored by the simultaneous operation of condenser 25. The telescope and gun may also control further variable resistances connected in bridge formation and adapted to provide a check on the positions of the control and controlled parts. In order to provide for control of the gun both in elevation and in azimuth two indentical systems are used. Fig. 3 shows the apparatus associated with the telescope for giving both controls. A periscopic telescope is mounted for rotation about a vertical axis YY to control the " azimuth " condenser 21<1> and a horizontal axis XX to operate the " elevation " condenser 21. The condensers are supported in a disc 81 which is rotatable in the casing 89 on a support 88 and carries pivots 2 for the sleeve 80 of the telescope 1. Corrections may be introduced into the settings of the condensers 21, 21<1> by knobs 107, Fig. 6, and 122, Fig. 8, respectively. The knob 107 controls the setting of a pivoted lever 104 which, through a pin-and-slot connection with lever 110 and gears 111, 113, operates the spindle 19 of condenser 21. The knob 122 operates, through an eccentric 120, a support 116 along a slideway 115 and rotates a gear 134 mounted on the condenser spindle 23 and engaging teeth on the casing 89. When large adjustment is necessary the gear 134 may be disengaged by a button 132 which when depressed lifts the plate 127 about a pivot 126. The gun is moved in elevation and azimuth about its axes by servomotors, the piston-rods of which are provided with hand wheels for facilitating hand training. The checking signals of the azimuth and elevation positions of the telescope and gun are given by two galvanometers, images of the pointers of which are superposed on the normal image in the reticule of the telescope.

Title: Loading pallet
IPC: B65D19/00
Filed: 1977-03-02
Abstract: The loading pallet has a fibre board (1) in which several rows of holes or depressions are formed. These serve for receiving sleeves (2) made of cardboard. The free ends of the sleeves located in one row can be connected in each case by a reinforcing strip (3), the connection between the sleeves and strips being the same as between the sleeves and board. The board (1), the sleeves (2) and the strips (3) are glued together. In this way, a pallet of low weight but of a strength comparable to wooden pallets is obtained. Since the most inexpensive material is used for the production, it can be ground after use for the purpose of recovery for new fibre boards and strips, thus obviating the need for expensive return transport of the used pallets. <IMAGE>
