Title: Heat treatment method and apparatus
Inventor: PARKER GARY F
IPC: G21C13/087
Filed: 1982-12-23
Abstract: An envelope (1) possibly made of stainless steel foil, having an expandible construction is inserted within the vessel (2) to be heat treated. The envelope (1) is caused to enlarge, by supplying a heated stream of fluid, e.g. supplied by a high velocity gas burner (11), so that at least a part of the envelope (1) makes contact with an internal wall portion of the vessel (2). The temperature of the heated stream of fluid is controlled for a predetermined period in order to heat treat the wall portion of the vessel (2). The invention is particularly useful to anneal a reactor vessel which has become embrittled by fast neutron bombardment, since it facilitates installation and reduces exposure of personnel to radiation. <IMAGE>

Title: Improvements in wire bonders
Inventor: OKIKAWA SUSUMU
IPC: B23K9/16
Filed: 1983-03-29
Abstract: A wire bonder useful for assembling electronic components with fine metallic wire. The wire bonder in accordance with this invention forms a ball at a free end of a bonding wire by utilizing discharge arc and thereafter bonds the ball to a component. The wire bonder of the invention has a construction in which the atmosphere between the tip of the bonding wire and a discharge electrode disposed adjacent the tip of the bonding wire can be maintained as a reducing gas atmosphere. Especially when an aluminum wire, which is an easily oxidizable thin metallic wire, is used as the bonding wire, the wire bonder of the present invention improves the sphericity of the ball formed by discharge arc as well as the bondability.

Title: Alkenyl succinic anhydride sizing composition and method for its preparation
Inventor: SWEENEY WILLIAM A
IPC: C07C57/13
Filed: 1983-08-18
Abstract: A liquid alkenyl succinic anhydride composition having superior paper sizing properties comprises:   (A) the reaction product of maleic anhydride and straight chain alpha olefins in the C13 to C18 range; and (B) the reaction product of maleic anhydride and straight chain internal olefins or branched chain olefins in the C14 to C22 range, component (B) having a molecular weight which is at least 10 units higher than component (A). The composition can be used for the sizing of paper of for imparting water-repellency to cellulosic fabrics. The composition can be produced from maleic anhydride and a mixture of straight chain alpha olefins in the C13 to C22 range by separating the alpha olefins into a lower boiling fraction and a higher boiling fraction, isomerizing the higher boiling fraction, and either recombining the two fractions and reacting them with maleic anhydride, or independently reacting them with maleic anhydride and then combining the reaction products. c

Title: Pumping apparatus actuated by the movement of a boat or other vessel
Inventor: MILLS CLIFFORD ERNEST
IPC: F04B19/02
Filed: 1984-03-29
Abstract: Pumping apparatus for use on a boat, buoy or other floating vessel is actuated by swinging movement of a weighted pendulum 16, 17 relatively to the pumping apparatus, in response to the motion of the vessel. The weighted pendulum is linked to a piston 12 reciprocable in a cylinder bore 11 of larger diameter and fluid coupled to a ram 8 reciprocable in a coaxial cylinder bore 9 of smaller diameter. The ram 8 is arranged to reciprocate a plunger 7 which deflects a diaphragm 4 for pumping liquid between inlet and outlet ports 5, 6 provided with non-return valves. The relative movement of the pendulum 16, 17 reciprocates the piston 12 and the stroke of this piston is transmitted, with increased amplitude, to the plunger 7 by means of the fluid coupling and the smaller diameter ram 8. Alternative mechanical amplification systems are described. <IMAGE>

Patent GB-2172522-A (GB)
Title: Pulper with dirt separator
Inventor: THUMM HELMUT
IPC: D21B1/34
Filed: 1986-03-12
Abstract: In the vicinity of its base the pulper has a radial extension in the form of a chute (2') or small tank, which in its upper region has an outlet aperture (4') for less heavily polluted suspension and in its lower region has an outlet aperture (3') for heavy dirt. The cross- section in the vertical direction of the chute gradually widens to the said outlet apertures, which are essentially connected at the radial end of the chute. The chute can also be constructed so that it abruptly extends from its inlet aperture (5'), the inlet aperture being constructed relatively small in relation to the cross-section of the chute in the vertical direction. As a result, it is easily possible to remove a large proportion of the heavy dirt from the pulper and the fibrous suspension and thus to relieve subsequent apparatus of the paper making plant. <IMAGE>
