Abstract: 1,222,680. Catamaran planing craft. E. J. GARMAN. 8 Oct., 1969 [9 July, 1968], No. 32715/68. Heading B7A. In a power driven waterborne or landborne craft comprising two planing hulls or skis 1, 2, a frame 3, 4, 5 and power unit 60 mounted on the frame, each hull or ski is mounted for pivotal movement about an axis fixed in the frame and parallel to the longitudinal axis of the respective hull or ski. Steering handle 4 adjusts the angular positions of the hulls or skis about their respective pivot axes so that they move in the same sense from their respective central positions. For land use over snow, sand or marshy ground the driving means could be an aerial propeller, a wheel, roller or endless track.

Title: Process of producing super strength steel bodies
IPC: C21D8/00
Filed: 1963-01-07
Abstract: <PICT:1023132/C6-C7/1> A hardenable steel alloy body containing at least 0.15% C is strengthened by austenitizing below its melting point, e.g. at 1475-1500  DEG F., mechanically deforming the body by more than 10% while at a temperature above that of the upper nose of the TTT curve characteristic of the alloy composition e.g. above 1200 DEG F., which nose represents the start of transformation of austenite into other products (ferrite, pearlite or bainite), and completing the deformation without isothermal transformation, then cooling the body to transform to martensite e.g. by rapidly cooling to room temperature and then further cooling to the temperature of a liquefied gas, e.g. liquid nitrogen, oxygen or CO2. Thereafter the alloy may be tempered at 600  DEG F. prior to again cooling to the temperature of liquid nitrogen.  Deformation may be effected by forging, rolling, extruding or drawing.  Examples of alloy compositions are identical to those specified in the original Specification.

Abstract: 980,472. Recuperative burners. BLOOM ENGINEERING CO. Inc. Aug. 29, 1962, No. 33143/62. Heading F4T. A recuperative radiant tube burner for a furnace comprises an alloy steel radiant U or W-tube 19 having inlet and outlet legs 17, 18 extending through the furnace walls 11, a gas or atomized oil burner 35 coaxially disposed in the inlet leg 17 and a recuperative heat exchanger 45 for heating the combustion air prior to its delivery to the burner, coaxially disposed in the outlet leg 18. A burner sleeve 22 mounted on the outside of the furnace wall by means of bolts 26 has a refractory lining 38, 39 and an annular cover 30 through which passes a gaseous pilot burner 33 and into which the burner 35 and its fuel supply pipe 36 are threaded. The pilot burner 33 is locked in lighting position by a thumb screw 34. The outer end of the leg 17, threadedly engages a flange 20 which is secured between a metal outside shell 14 of the furnace wall and the sleeve 22 by means of the bolts 26. The leg 18 similarly engages a flange 21 and is secured by means of bolts 27 which also mount a sleeve 23 of the heat exchanger 45, on to the furnace wall. The sleeve 23 has a refractory lining 43, an exhaust gas opening 48 coupled to an outlet pipe 49 and an annular coverplate- 55 through which passes a combustion air supply pipe 50 which may be welded thereto. The pipe 50 extends within, and terminates outwardly of the end 46 of the heat exchanger 45. The latter may be welded to a flange 54 which together with the plate 55 is bolted to the sleeve 23. Radial heat exchanger fins 52 on the inner wall of the exchanger extend into an annular air passage between the exchanger wall and the pipe 50 and a flanged opening 53 is provided adjacent a side opening 44 in the sleeve 23. A refractory insulated pipe 41 conveys air from the heat exchanger to a side opening 40 in the burner sleeve. The ends of the pipe 41 are recessed to receive labyrinthine wire seals 58 which may be secured by welding or brazing. The pipe 41 also engages an annular shoulder 57 in the opening 53 and has a collar 59 to inhibit exhaust gas leakage through the opening 44. The draft through the radial burner is induced either by a suction fan coupled into the outlet pipe 49 in which case air is aspirated through the pipe 50 or by a blower upstream of the air supply pipe 50, or both. In a modification, Fig. 5 (not shown), for a higher heat exchange, the heat exchanger and its sleeve extend a greater distance outwardly from the furnace.

Abstract: 1498141 Polymerized olefin polymerization catalyst component NAPHTACHIMIE 11 Aug 1975 [14 Aug 1974] 33397/75 Heading C3P A solid olefin polymerization catalyst component is obtained by (a) polymerizing an olefin in the presence of a catalyst comprising solid particles of a transition metal compound and an organomagnesium compound under specified conditions which yield a reducing solid with a small amount of polymer associated therewith and (b) reducing a further transition metal compound with the product of step (a). The component may be obtained by using an olefin as such or, if a halohydrocarbon is employed instead, it may be prepared in situ by a dismutation reaction with the organomagnesium material. The organomagnesium compound may also be formed in situ from magnesium and a halohydrocarbon. The catalyst component may be combined with the usual organometallic compounds to form the catalyst. The component may also be treated with materials such as water or alcohols before step (b) is effected. In examples, the catalyst components are formed by polymerizing ethylene in solution, in n-heptane in the presence of hydrogen and of a propoxychlorotitanium (in spherical particulate form) and ethyl magnesium chloride, to yield the polymeric reducing solid in the form of small spheres. This component is then (i) combined with dipropoxytitanium dichloride and ethyl chloride in heptane together with i-Bu 3 Al, or (ii) treated with water or n-butanol, and then combined with TiCl 4 , together with i-Bu 3 Al, and the resulting catalysts used for the solution polymerization of ethylene in the presence of hydrogen.

Patent GB-984071-A (GB)
Title: Hydroxy functional polymers and method of making the same
IPC: C07C29/132
Filed: 1963-08-26
Abstract: Olefinic polymers may be converted to hydroxy functional polymers of lower molecular weight by converting a portion of the olefinic bonds of the polymer to ozonide linkages and reductively cleaving the thus produced ozonide linkages to produce a hydroxy functional polymer. The ozonization may be effected by passing ozone, preferably mixed with a gaseous carrier such as oxygen, through a solution of the polymeric material in a solvent such as chloroform in an amount such that one mol. of ozone is introduced for each two to six unsaturated repeating units of the polymeric starting material.  The resulting ozonide is recovered and then reduced and cleaved by reaction with a strong reducing agent, preferably a hydride of a light metal such as lithium hydride, aluminium hydride or lithium aluminium hydride. Preferably the reducing agent is added to a solution of the ozonide cooled below room temperature until present in excess and the reaction mixture is then warmed until reductive cleavage occurs.  The preferred polymers treated according to the invention are stereo regular polymers which include natural materials such as rubber, balata and gutta-percha.  In the example, a cis-1,4-polybutadiene prepared using a Ziegler-Natta catalyst is treated according to the invention.
