Title: Improvements relating to variable speed power transmission mechanism
IPC: F16H15/36
Filed: 1934-11-30
Abstract: 448,254. Variable - speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A. Nov. 30, 1934, No. 34498. [Class 80 (ii]) In variable - speed friction gearing of the torus disc type having one roller set or twin sets in which the loads are equalized among the rollers of a set by differential precession initiated by an equalizing-device which is subject to the load reaction and is concentric with the main shaft of the transmission, the said equalizing- device is mounted without provision for radial movement. In the arrangement of Figs. 10 and 13 of Specification 392,589, an equalizing control sleeve 189 is mounted loosely or floatingly about its shaft so as to induce the differential precession to equalize the loads on the rollers of each set. Under this invention, the corresponding control sleeve 1, Fig. 1, which is displaced angularly to effect speed changes, encircles the main shaft, not shown, without radial freedom thereon. As in the arrangement of the Specification referred to, the stems 10, 11, 12 of the roller - supporting rockers 20 all transmit load reaction to a common cam ring 6, and each stem thrusts the ring 6 independently towards low-speed position. The ring 6 is connected to the sleeve 1 through a universal or Hooke's joint 5, 4, 2 so that it can swing universally to effect a balance between the axial components of the thrusts of the stems 10, 11, 12 upon the ring, and therefore between the traction loads on the rollers corresponding. Since the cams or inclined slots 7, 8, 9 of each ring 6 are all of the same hand, by opposing the hands of two cam rings 6 as shown in Fig. 2, the sleeve 1 will by axial displacements equalize the loads between twin roller sets reacting on the two rings 6 respectively. This universally supported ring split along an axis A A, Fig. 3, into halves 6a, 6<b>, is adapted to equalize between four rollers of the same set. If the ring were solid, it would swing about an axis C C to equalize between aligned stems 16, 18 and about an axis D D to equalize between stems 17, 19, but it would not equalize between these two pairs of stems and the corresponding pairs of rollers. By splitting the cam ring along the diametral line A A, equalization between the four stems is attained. The joint pins 2 may be prolonged between the ends 6<a>, 6b of the split ring as shown in Fig. 4. Twin sets each with four rollers may be balanced one against the other by a slidable sleeve such as 1 with such split cam rings of opposite hand at its ends. Specifications 392,570 and 415,922 also are referred to.

Title: Improvements in bag-sewing apparatus
IPC: D05B13/00
Filed: 1932-12-07
Abstract: 403,803. Sack-sewing machines. McALISTER, A., 281, Forbes Street, Darling- hurst, near Sydney, Australia. Dec. 7, 1932, No. 34646. Convention date, Dec. 24, 1931. [Class 112.] Hand apparatus for sewing the mouths of filled sacks has a horizontal hook needle with a latch, co-operating with a looper for producing a chain stitch with thick thread such as twine. The twine 64 is threaded through the eye 63 of the looper 60 and one of the openings 35 in the channel 21 ; the needle 31 is moved forwardly to pierce the mouth 22 of the bag 23. The tracked cam 51 has now been rotated and the looper 60 is also moved at the completion of the forward stroke of the needle 31 to draw the twine 64 across the needle hook 32, this hook being uncovered by the latch 33 by engagement with the bag during piercing. The needle is then moved rearwardly to draw the twine through the bag, forming a loop 125 which is covered by the reverse movement of the latch on withdrawal of the needle from the bag. The cam 51 rotates to move the looper 60 again to place the twine in the needle hook on the next forward stroke. The next rearward stroke of the needle passes the new loop through the previous loop 125 to form the stitch. On the commencement of each forward stroke of the needle 31, the downwardly projecting pin 85 of the needle block 24 operates to move the sewing-apparatus step by step along the bag clamp limbs 115, 116. During the piercing and looping operations a pawl locks the sewing apparatus upon these clamp limbs till such operations are completed. The closed and folded mouth of the bag travels in a channel shaped guide 21 provided with holes for passage of the needle. The needle carrier 24 is reciprocated and the cam 51 rotated bv a hand lever 38 and crank 37, Fig. 1, or by the manually rotated crank disc 42, Fig. 11. Thread-spool holders.-The thread-spool is held on a spindle between rotatable conos held by a spring and nut.

Title: Improvements in or relating to the treatment of bamboo, bagasse and other fibres forthe extraction of cellulose therefrom
IPC: D21C1/02
Filed: 1922-12-22
Abstract: 213,003. McRae, W. A. R. M. Dec. 22, 1922. Pulp, preparation of.-In order to overcome the difficulty, arising from the differences in age, growth, and season of cropping, in the preparation of an uniform cellulose from bamboo, bagasse &c., the raw material is subjected to a preliminary hydro-mechanical operation by which a pecto-ligno-cellulose of substantially standard quality is produced, from which the pecto and ligno constitutents may be removed separately, or together, in known manner with caustic soda or other suitable material. By the hydro mechanical operation, consisting of a beating and opening up in water, non-fibrous carbohydrates such as parenchyma, pith, starch, and sugar, are separated from the fibres and washed away. The operation may be conveniently carried out in apparatus such as is described in 213,004. The separated non-fibrous material is subsequently collected, dried, and used for fuel in a sugar factory. Bagasse from the same factory may be similarly treated, yielding a pecto-ligno-cellulose and also fuel. Sizal, agave, rhea, hemp, manilla, flax, and like materials may be treated according to the present process. Specifications 16682/12, 17834/14, and 180,097 are also referred to.

Title: Improvements in or relating to metal vapour electric arc converters
Inventor: HOLLIDAY JOHN HUBERT
IPC: H01J13/32
Filed: 1955-12-06
Abstract: 810,387. Metal-vapour converters. GENERAL ELECTRIC CO. Ltd. Nov. 26, 1956 [Dec. 6, 1955], No. 35038/55 Class 39(1). In a metal vapour electric arc converter having a cathode formed by a pool of mercury or other vaporizable liquid metal, a cathode spot anchoring arrangement comprises an inverted cup-shaped member, constituted by a spinning or pressing of heat-conducting material such as molybdenum or tungsten capable of being wetted by the liquid metal, arranged with its upper end projecting above the surface of the liquid cathode to produce a cathode spot anchoring edge and cooled by cooling fluid impinging directly on its inner surface. The cup-shaped member 22 is sealed to a tubular member- 21 which projects up through the cathode vessel 2. Cooling fluie passes through an inlet pipe 25 into an annular passage between the members 21 and 22 and a flanged tubular member 23 and out through the opening 24. Alternatively the anchoring member 22 may be cooled by forcing carbon dioxide under high pressure through flne orifices in a tube projecting into the members 21 and 22. The carbon dioxide expands adiabatically and in cooling some of the gas solidifies on the inner surface of the anchoring member. A cylindrical wall 5 of glass connects the cathode vessel 2 to a metallic member 6 which is brazed to a steel cylinder 7 provided with a connection 8 for a vacuum line. A steel bowl-shaped anode 4, insulated from the steel cylinder 7 by a ring 9, completes the envelope and is provided with a copper terminal 11. The anode is cooled by an arrangement similar to that by which the member 22 is cooled. An auxiliary anode 13 and an igniter electrode 14 are positioned above the cathode in known manner. The envelope of the rectifier is cooled by means of a cooling jacket 31 which may include a window 35 to allow observation of the cathode. In an alternative arrangement, Fig. 2, (not shown), the cathode spot anchoring arrangement comprises a plurality of inverted cup-shaped members spaced closely from one another so that the cathode spot can extend from one member to another without becoming detached from the anchoring edge, each member being cooled by cooling fluid impinging directly on its inner surface.
