Title: Improvements in distilling petroleum oils
Filed: 1920-03-17
Abstract: 164,529. Kormann, F. A. March 17, 1920. Hydrocarbons, distilling and cracking.-In distilling heavy oils to obtain lighter oils, the oils are subjected to the action of heat and steam,. while absorbed in a porous substance such as the porous bricks known as nonpareil bricks prepared by mixing powdered cork with the materials before burning the bricks. A still A is almost filled with bricks which rest upon an angle-iron frame I and is heated by hot gases from a burner M,. which also heat steam superheaters N, N<1> consisting of inclined coils of pipes. Steam from the superheater N is passed by a pipe O to coils O<1> on the base of the still and is then passed through superheater N' and through pipe O<2> and perforated pipes p<4>, p<5> into the oil. The still is preheated to about 300‹ F. by passage of steam through the coils O<1>, oil is then admitted, and distillation commences. The temperature is increased by applying direct heat to the superheaters, and in the later stages of the distillation superheated steam is passed directly into the oil. The residual oils are withdrawn from the base of the still. Fresh oil may be supplied to the still during the distillation.

Abstract: 1424139 Adhesive flexible jointing tapes A W WAKEMAN 20 Feb 1973 8190/73 Heading B2E [Also in Divisions B5, Dl, E2 and F2] An adhesive coated longitudinally flexible tape 20 for joining the edges of adjacent members F, G, Fig. 10, has an X like configuration in cross-section comprising two pliable carrier strips 24 bent to form the quadrants of the X, and spaced connector means 22 intersecting and crossing each other to connect the strips 24, the two sets of axis crossing connector means being free to shift relative to each other in the region of the tape axis within the limits defined by their points of connection to the respective carrier strips. The strips may be kraft paper, crepe paper, woven fabric plastics film or metal tape. Strands 22 may be multifilament threads or cords of natural or synthetic material or organic or metallic monofilaments including rigid rods. Groups of e.g. 4 parallel strands (82, Fig. 13, not shown) may be used in place of individual strands. The strands or groups of strands are perpendicular to the longitudinal axis of the tape or at an angle to the tape. In the embodiment -of Figure 17 the tape is an integral woven structure in which weft threads 222 of the strip act as connectors. The tape of Fig. 1 is produced by winding cord 36 in a figure of eight manner about two elongated flat mandrels 34. Sheets 24 of pressure-sensitive tape are applied over the cord on opposite faces of the mandrels and the cords cut at the outer edges of the mandrels. In Fig. 5 (not shown) the cord is wound about a plurality of double width mandrels to produce several tapes simultaneously. The mandrels may be faced with tapes 24 before winding cord 36. The cord may be wound about the tapes without using mandrels. Adhesive may be applied to the side of tapes 24 remote from connecting strands 22, thus facilitating a flexible connection, or to the sides bearing strands 22. Preferably the adhesive (102, Fig. 15, not shown) extends from the margins of the tape only part way to the apex. Release sheets (104) cover the adhesive and overlap it towards the apex thereby providing a free portion (106) with which to start peeling of the release sheets when the tape is used to join members.

One end of the sheath 2 is secured to the mandrel by a tapering ring 3. Pivoted shoes (105) Fig. 2 (not shown) or rollers (100) Fig. 1 (not shown) press the sheath 2 against the mandrel 1 or, in the latter arrangement, additionally against further rollers which are mounted on the tube 4. In one embodiment, Fig. 4, refuse falls into a chamber B and is compacted in batches against a hinged gate E by a ram D. The gate E is then released and the ram D discharges the batch of refuse into the sheath 2 which has been sealed at its bottom by two welding jaws (5a) Fig. 3 (not shown) and 5b. Upon detection of the closed bottom of the sheath 2 at a predetermined level or after a predetermined number of ram strokes, the welding jaws (5a), 5b weld and cut the sheath to produce an individual filled and closed bag and the next bottom closure weld in the sheath 2. The closed bag, supported on a platform 7, is then tipped on to a trough 10. In a second embodiment, Fig. 9 (not shown), material is compressed in a horizontal tube (4) against a movable back-up plate (20) which closes an end of the tube. In operation the sheath is closed at one end by welding jaws (5a, 5b), the plate (20) is moved against the end of the tube (4) and batches of product, each having a predetermined volume, are compacted by a ram (18) until the tube is full of compacted material. This state is detected automatically by a sensor or by counting the strokes made by the compaction ram (18). The plate (20) is then withdrawn and the compaction ram (18) and a further ram (27) Figs. 5- 8 (not shown) which is mounted back-to-back with the ram 18, act to eject the compacted material which entrains a portion of the sheath during its ejection. The sheath is then welded and cut as in the previous embodiment.

Abstract: The hydrolysis of hydrochloric acid solutions of titanium is effected after the addition of insoluble nuclei of titanic acid which have been produced in solutions having a pH value of 3,5 or under.  For instance, a portion of the main solution may be treated with alkali until its pH value is 2-3 and be heated to 80 DEG  C. for half an hour to form the nuclei which are then stabilized by rapidly cooling to 50 DEG  C.; the suspension obtained or the filtered and washed nuclei are then added to the main solution and hydrolysis effected by heating, say, to 100 DEG  C.  The titanic hydroxide obtained is washed, calcined at 900-950 DEG  C., preferably with the addition of say 2 per cent of potassium bisulphate, and then ground wet and dry to prepare it for use as a pigment. Hydrolysis may be effected in the presence of barium sulphate or other pigments or fillers when composite pigments are desired.

Abstract: 1,096,607. Self-processing cameras. INTERNATIONAL POLAROID CORPORATION. March 1, 1965 [March 2, 1964], No.8658/65. Addition to 1, 059, 849. Heading G2A. In a self-processing camera, the sheet of light-sensitive material in a container 54 is housed in a compartment 44, the sheet being led out through an opening 60, across the exposure aperture 36, and on to a pair of pressure rollers 74, 76. The print-receiving sheet 62 is impregnated with a highly alkaline processing liquid, and hence has to be kept in a sealed container 66 to prevent evaporation and chemical contamination. The slot 68 through which sheet 62 leaves this container is sealed up, and broken open only as the container is loaded into the camera. The camera housing comprises a rear section 38 and a front section 18 hinged together, shown in closed operative position in Fig. 2 and open inoperative position in Fig. 3 (not shown). The container 66 is loaded into a U-shaped member 90, which is sealed in the Fig. 2 position by a closure 92 pressed against it. When the camera is opened (Fig. 3), the member (90) pivots out of its compartment, and the closure (92) also pivots away from member 90. The container 66 can now be loaded into member (90), the leading end of the print-receiving sheet threaded between rollers (74, 76), and the two sections of the camera closed again, back to the position of Fig. 2. A crank (100) Fig.4 (not shown) external of the camera housing is keyed on a shaft (102) which also carries a drive gear 110. This drives, via a gear train, the pressure rollers 74, 76, to advance and press together the film sheets. Cams 104 on shaft 102, which normally press closure 92 tight against member 90, are so disposed that the pressure is relaxed during the film feeding movement, so that the closure can open sufficiently to allow sheet 62 to move freely between members 90 and 92. A cutter bar 122 is provided, and is also operated by rotation of shaft 102 to sever the film sheets from the remainder of the rolls after they have passed out of the camera through slot 78.
