Title: Improvements in or relating to process of preparing hydroxypropyl cellulose
IPC: C08B11/08
Filed: 1964-02-07
Abstract: Hydroxypropyl cellulose is made by mixing cellulose material, alkali and water in the presence of liquid propylene oxide as a diluent, the alkali/cellulose ratio being 0.02-0.5/1, and then etherifying to an M.S. of at least 2.0 by allowing a portion of the propylene oxide to react with the alkali cellulose formed. The ingredients of the reaction mixture may be brought together in any order.  In one embodiment, excess liquid (mainly propylene oxide) is removed from the alkali cellulose to a press ratio of 2.5-8/1 prior to etherification, which may then be carried out without further addition of diluent or in presence of an organic diluent other than propylene oxide.  If liquid is not removed from the alkali cellulose, etherification is effected in presence of the excess propylene oxide. The cellulosic material is preferably comminuted cotton linters or wood pulp. Suitable alkalis are sodium and potassium hydroxides and organic bases such as methyl and methyl benzyl ammonium hydroxides, while specified organic diluents are dibutyl ether, diisopropyl ether, hexane, heptane, benzene, toluene, xylene and cyclonexane. Etherification may be carried out as described in Specification 1,028,723.  The hydroxypropyl cellulose is soluble in water and in many polar organic solvents and has excellent thermo-plasticity.

Filed: 1929-02-19
Abstract: 307,062. Sargent & Lundy, Inc., (Assignees of Rossman, A. M.). March 3, 1928, [Convention date]. Couplings. - To provide against interphase short circuits, bus-bars in the form of cables are individually insulated by being composed of conductors 1A, 1B, 1C, Fig. 1, covered with fibrous or like insulation 2, itself immersed in self-healing insulation, e.g. light oil 5 contained in a copper &c. sheath 3, which is thin and so is supported on a framework 4, which restores the rigidity lost by economizing copper. The individually insulated busses can now be brought closer together than is normal in the isolated phase system, while the liquid and copper surrounding the conductor help to dissipate heat. In practice, the framework supports the system well clear of the ground, the bus-bars being above and the circuit-breakers, transformers, &c. below, the actual supporting platform. The cables are made in standard lengths connected by junction boxes which serve also for attachment to the frame. Mounting and removal of the individual cable sections is facilitated by staggering them as shown at 30, 31, 32, Fig. 4, adjacent ends being joined by vertical connections. Electrical continuity of the sheaths is prevented by ' means such as insulating gaskets suitably interposed between sections. Distance pieces are used to keep the inner tubes 2 clear of the sheathing 3. The ends of two adjacent lengths 360, 380, Fig. 9, of the sheath are secured by flanges 361, 381 to members bolted to the two elements 368, 370 of what may be called a sliding spigot and socket joint, these elements carrying between them a flexible diaphragm member 366 secured by soldering and by clamps 373 and protected against damage by a thin metal cylinder 383. Similar means is employed to join a sheath length to a junction box. Specification 299,335 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes and shows, Figs. 26 (Cancelled) and 27, a conductor comprising a sixstrand cable wrapped round a central rod, the ends 343 of each strand 344 being triangular with a spider 342 holding them apart, while a copper casting 345 surrounding the ends is bolted to a lug 346.

Title: Improvements in connection with gramophones
IPC: G11B3/095
Filed: 1925-02-28
Abstract: 252,462. Burke, A. E. O. Feb. 28, 1925. Returning sound-box to starting point; tonearms; tone-arm joints; sound-boxes and tonearms, balancing.-Relates to gramophones having a number of sound-boxes, one of which automatically repeats the playing of a record as soon as the reproduction by another sound-box has finished. According to the invention, two or more sound-boxes are mounted on the same or on separate axes at the end of a tone-arm, and are so arranged that they are moved simultaneously by the action of the record track upon the needle which for the time being is in action, one sound-box reaching the starting position as soon as sound reproduction by another has finished, and all the sound-boxes starting from the same side of the centre of the record and moving over approximately the same path. In the construction shown, three sound-boxes A. A', A<2> are carried by tubes C, C<1>, C<2> which are joined to a common sleeve D rotatable upon a hollow apertured spindle which is clamped within the end of a tone-arm F. The axis of the hollow spindle is slightly inclined, so that one reproducing needle only is in playing engagement with the record track at the same time. When one needle (e.g. the needle B) has reached the end of the track after playing the record, the needle of the next sound-box (B<1> in this case) has been moved into contact with the outer part of the track and then repeats the playing, the first needle (B) moving out of contact with the surface of the record. This action occurs repeatedly. The distances between the needles can be adjusted in accordance with the width of the soundgroove zone by rotating the sound-boxes on their axes in the supporting arms. The tone-arm F is mounted on a fixed sound-conduit H by a ball- and-socket joint F<1>. A forked lever K engaging the end of the tone-arm F and provided with weights K<2> for counterbalancing the sound-boxes and tone-arm is mounted on trunnions K<1>. The lever K mav be turned into engagement with clips L to hold the arm F and the sound-boxes raised. In a simplified construction involving only two sound-boxes, these are pivoted on separate inclined axes at the end of a tone-arm which is mounted on trunnions. The sound-boxes are linked together. This arrangement provides only for one automatic repetition of the sound reproduction.
