Title: Spacer means for cryogenic coaxial tubing
IPC: F16L59/153
Filed: 1969-07-17
Abstract: 1282013 Laminates VACUUM BARRIER CORPORATION 17 July 1969 [24 July 1968] 36016/69 Heading B5N [Also in Division F2] A spacer material 14 (Fig. 1) comprising a strip 20 of fibrous thermally insulating material, the fibres being orientated mainly in directions normal to the height of the strip, and an abrasion resistant facing or facings 22 bound thereto by strand material 26 is helically wound around inner tube 10 with spaced convolutions. Extra layers of insulating material 20 (Fig. 5) may be added at intervals along the strip to provide spaced support areas 36, so that contact with the outer tube 12 is restricted to those areas. Precompression of areas 36, or of the whole strip, increases the stability of the spacer. Alternatively, a second strip 52 (Fig. 7, not shown) may be wound about 10 in the opposite direction, so that outer tube 12 is supported only where the strips overlap. Evacuation of the space between the tubes, to reduce convection, may be aided by incorporation in the strip of "getter" particles 44 (Fig. 6, not shown) to absorb residual gases. The getter particles are protected from the atmosphere by packaging the strip in moisture resistant tubing which is ruptured just prior to installation of the strip. A cryogenic pipe (Fig. 8) utilizes fibrous spacers 14, 35 to separate the innermost tube 60, containing the cryogenic fluid, from tube 62, and tube 64 from layers of fibrous insulating material 70 and outermost tube 66. The annular spaces maintained by spacers 14 and 35 may be evacuated. Cooling fluid may be passed through the space between tubes 62 and 64, which are separated by a helically wound conventional plastics or other solid spacer 68. The pipe may be used as a superconducting cable by placing a liquid helium and a suitable conductor inside tube 60.

Abstract: 508,496. Pneumatic despatch apparatus; endless - belt conveyers. LAMSON ENGINEERING CO., Ltd. (Lamson Co.) Dec. 31, 1937, No. 36239. [Class 78 (i)] Magnetic means are provided by which carriers of a certain type are separated from a heterogeneous line of carriers and directed to a predetermined destination. The line of carriers is advanced by a belt 21, Fig. 1, below a belt 23 which passes around a pulley 25 of the magnetic type. The magnetic carriers 36 are raised from the line and travel with the belt 23 around the pulley 25. Since the surface of the pulley not in contact with the belt is rendered non-magnetic, the carriers continue to travel with the belt to a tube 27 through which they are drawn pneumatically. The non-magnetic carriers 35 are delivered to a shoot 28. In a modification a magnetic pulley acts directly on the carriers and transfers them to a pneumatic tube. In another modification a magnetic belt 60, Fig. 9, is used to separate and transfer the carriers. In further modifications the separation is effected by a magnetic plate in front of which travels an endless belt.

Novel compounds of the formula (I) COOH-CHNH 2 -(CH 2 )m-CHF- (CH 2 ) n -(CHNH 2 ) p -COOH wherein m is an integer from 1 to 4 inclusive, n is 0, 1 or 2 and p is 0 or 1, but when p is 0, n is also 0, are obtained by treating a fluorinated dicarboxylic acid HOOC.CH 2 (CH 2 ) m .CHF(CH 2 ) x  COOH, where x is 0, 1, 2 or 3, with bromine whereby a bromine atom is substituted for a hydrogen atom in a position adjacent to a carboxy group and substituting the bromine atom with an amino group by the action of an aminating agent, such as ammonia or potassium phthalimide. The compounds are useful antimetabolites. The following intermediates are also described: α-Fluoropimelic acid dichloride is obtained by refluxing α-fluoropimelic acid with SOCl 2 , and the dichloride is reacted with Br 2  in the presence of strong light at 90‹ C. to form α-fluoro-α<SP>1</SP>-bromopimelic acid. γ-Nitropimelic acid dimethyl ester is obtained by reacting together nitromethane, triethylamine and methyl acrylate. The ester is hydrolysed with conc.HCl to form γ-nitropimelic acid which is hydrogenated to γ-aminopimelic acid. The latter is heated to melting point under nitrogen and kept at 180-200‹ for 1 hour, and 2-pyrrolidone-5- propionic acid is obtained. This product is dissolved in aqueous HF and treated with NaNO 2  with heating and γ - fluoropimelic acid is obtained. The latter is converted by the above method successively to α,α<SP>1</SP>-dibromo-γ-fluoropimelic acid diethyl ester and α,α<SP>1</SP>-diphthalimido- γ-fluoropimelic acid diethyl ester.

Abstract: 1365920 Adjustable seat backs A & M COUSIN ET CIE ETABS COUSIN FRERES 4 Aug 1971 36618/71 Heading A4J [Also in Division E2] In a hinge fitting for the adjustment of the inclination of the backrest of a vehicle seat, each of the members 1, 2 which are attached to the backrest 4 and seat pad 5 respectively and are mounted on a tubular bearing 3, is formed with a plurality of holes 6, 7 extending along the circumference of a circle, the number of holes in one member being one less than the number of holes in the other member, e.g. eighteen holes in member 2, nineteen holes in member 1, such that in any position of member 1 relative to member 2 a number of holes in each member are in alignment and/or partial alignment, with a number of a plurality of locking members 11 passing through the aligned and/or partially aligned holes. As shown in Figure 2 the backrest is locked in position. To change the angle of inclination of the backrest, an operating lever 19 attached to a casing 17 is rotated causing rotation of casing 17 which effects axial movement of the casing (in the direction of arrow F 2 ) together with a shaft 16 which passes through the tubular bore 3. Axial movement of the shaft brings each of the teeth 31 of a plate 30 into engagement with a hole 6 in the member 1, the number of teeth 31 being equal to the number of holes 6, thereby forcing the number of the locking members 11 out of the holes 6 which are aligned and/or partially aligned with holes 7 in member 2 so that the inclination of the backrest can be adjusted. When the backrest is in the desired position the lever is released and the casing 17 is biased by a spring 20 to the position shown in Fig. 2 in which a number of the locking members pass through the aligned and/or partially aligned holes in the two members, thereby locking the backrest in the adjusted position. In a modification Figs. 9-18 (not shown) movement of the locking members out of engagement with the aligned and/or partially aligned holes is effected by a plate (55) mounted on the same side of the joint as the locking members 11.
