Title: Production of metal powder
IPC: B01D21/00
Filed: 1978-09-19
Abstract: In the manufacture of metal powder by the water atomization of liquid metal, the resulting slurry of powder and water is pumped into a settling tank having a separate receptacle 3 constituting the bottom of the tank. A filter screen 10 is provided in the receptacle and the powder settles on to the filter screen. Supernatent water is drained from the tank, and the receptacle is then removed from the upper part of the tank and a cover 15 is fitted to the receptacle. Air, which can be heated, is forced into the receptacle to force remaining water down through and out of the settled powder. <IMAGE>

Title: Improvements in or relating to electrical signal delay equalisers
IPC: H04B3/14
Filed: 1978-10-27
Abstract: A delay equaliser in which the dependence of the delay upon the frequency is adjustable has a separate all-pass unit connected between each adjacent pair of amplifier stages (V1, V2, V3, V4) in a cascade chain, the all- pass units each consisting of a bridged T-element with a centrally tapped variable inductance (L1, L2, L3) bridged by a variable capacitor (CT1, CT2, CT3) to form a parallel resonant circuit. Delay distortions, particularly frequency-dependent tilting of the delay curve, are equalised by providing for each all-pass unit a respective series combination of a capacitance diode (DV1, DV2, DV3) and a further capacitive element, this series combination being connected in parallel with the associated variable capacitor (CT1, CT2, CT3) of the all-pass units, and all the capacitance diodes (DV1, DV2, DV3) being connected to a common bias voltage source (UB) via an individual variable resistance (RV1, RV2, RV3), one for each all-pass unit, and fed from a common variable resistance (RL). <IMAGE>

Title: Apparatus for forming end stop blanks and attaching the same to a fastener chain
IPC: B21D43/11
Filed: 1979-01-02
Abstract: The rotation of a drive shaft 16 is translated by a dual crank mechanism 21 into the reciprocation of punches 33,38 at a blank forming and applying station, where successive unit lengths of a continuous metal strip 14 are cut off, bent into end stop blanks, and applied to a fastener chain to form top or bottom stops. For the delivery of the successive unit lengths of the continuous strip to the blank forming and applying station, a feed lever 59 is pivoted at one end and oscillated by a cam 61 geared to the drive shaft. The feed lever carries on its free end a fixed abutment 68 and spring- energized feed paw 69 which coact to firmly engage the continuous strip therebetween during the pivotal motion of the feed lever toward the blank forming and applying station and to substantially disengage the continuous strip during the pivotal motion of the feed lever away from the station. <IMAGE>

Patent GB-2062279-A (GB)
Title: Testing Apparatus for Transmitting and/or Receiving Electro-magnetic Radiation
IPC: G02B3/00
Filed: 1980-09-15
Abstract: Apparatus, such as a scanning telescope or a laser mounted on a tank or ship say can often only be tested and aligned properly by, somewhat inconveniently, removing it and transporting it to a test station. It is known, for ships, to carry test equipment which is deck mounted at some distance from the telescope and which is brought into use by swinging the telescope round to a test position where it is directed at the test equipment. Here, however, the test equipment is somewhat vulnerable and, due to the separation between it and the telescope, the test procedure is disadvantaged by stray electro- magnetic radiation, bending and twisting of the ship, mist, sea spray and so on. In this invention, apparatus, such as a scanning telescope (10) mounted for movement (13) around an axis (a), e.g. by means of a rotatable gymbal (13), can be moved to a test position where it is looking along the axis towards closely adjacent test equipment (21), for example, mounted in a recess (16) just below the telescope. Optionally a movable hood (17) prevents interference due to spray and stray radiation during testing and a shutter, e.g. an iris 19, protects the test equipment at other times. <IMAGE>
Patent GB-2059286-A (GB)
Title: Process and system for humidifying air for air-conditioning
IPC: F24F6/16
Filed: 1980-09-23
Abstract: Air which has been drawn in by means of a fan-wheel (30) is subjected to humidification in a first humidification stage (I), where water emerging from an annular chamber (16) is whirled up and disintegrated into droplets of wide size spectrum by the blades of a fan-wheel (30). The air is led through a drop-separator (36), which separates out the large drops, but allows the fine water droplets, which are required for humidifying and cooling the air to pass through. At a second, downstream, humidification stage (II) a second humidification stage takes place with the air being subjected to a water fog containing very small water droplets. <IMAGE>
