Patent GB-412600-A (GB)
Title: Improvements in apparatus for applying treating agents to yarns and like products
IPC: D06B11/00
Filed: 1932-10-28
Abstract: Apparatus for applying modifying liquids at intervals to artificial &c. yarns comprises liquid-applying means such as a roller 6, Figs. 3 and 4, a guide 4 for the yarn A by which it is normally held out of contact with the roller, a contact member or members 21, mounted on a shaft 20 and by means of which the yarn is pressed into contact with the roller, and means operatively connected with the driving means for automatically varying the speed of the shaft 20.  As shown, these means comprise cone-and-belt gearing 22, 23, 24, the belt being reciprocated by a forked lever 27 connected by a link 29 to a crank on a gear-wheel 30 driven through reduction gearing.  An alternative form of apparatus comprises a multi-point cam 14, Fig. 1, the wiper 12 of which is mounted on a shaft 8 having one or more arms 9 by which the yarn is depressed into contact with the roller 6.  The cam 14 is so shaped as to produce a varying time interval between successive passages of the contact member 9.  By these arrangements a high degree of irregularity in the application of the modifying liquid can be secured, and the yarn so treated may be worked up into woven and knitted fabrics free from streaks and "wood-grain" effects. The <PICT:0412600/IV/1> <PICT:0412600/IV/2> <PICT:0412600/IV/3> <PICT:0412600/IV/4> modifying liquid may be in the case of cellulose acetate &c. materials a saponifying agent as in Specification 332,263, [Class 15 (ii)], or a dyestuff or reserve as in Specifications 332,290 and 332,565, [both in Class 15 (ii)], or an agent which softens the filaments so as to cause coalescence as in Specification 325,823, [Class 2 (ii)].  The Specification as open to inspection under Sect. 91 describes a further form of apparatus in which the yarn is lifted from the roller 6, Fig. 3 (Cancelled) by means of projecting pieces 19 of different lengths and spaced at intervals of varying length on an endless chain or belt 16.  This subject-matter does not appear in the Specification as accepted.

Abstract: 396,965. Tilting-pad bearings. AKTIEBOLAGET NOMY, 2, Norrmalmstorg, Stockholm. Feb. 13, 1932, No. 30543. Convention date, Feb. 13, 1931. Divided on 396,808 and addition to 378,713. [Class 12 (i).] In a tilting-pad bearing of the kind claimed in the parent Specification, the members preventing undesired peripheral displacement of the pads 2 comprise annular discs 22, rings or the like, located in grooves 23 in the interior of the pads 2, the said discs 22 also preventing unintentional removal of the pads from the supporting member 3. The rings 22 may be split or resilient. As shown in Figs. 1 and 2, each disc 22 has projections 24 holding a pair of blocks diametrically arranged. The outer discs 25 are conical and resilient so that they can be snapped into position. The pads 2 which have ribs 16 entering grooves 17 in the carrier ring 3 are supported on the latter so that they operate in the manner described in Specification 290,637, [Class 12 (i), Bearings &c.]. In a modification the groove 23, Fig. 15, for the discs 22, the projections 7 on the carrier ring 3 for rotating the pads, and the ribs 16 are arranged side by side. The side faces 31, 32 of the groove 30 for the ribs 16 are at different inclinations. In another modification, the discs 22, Fig. 11, surround ribs 11 formed on the carrier ring 3 and engaging grooves 13 in the pads 2. A further modification has all the discs 22 plane, two discs being employed to connect a pair of diametrically arranged pads. In the construction shown in Fig. 22, grooves 33 are formed completely around the carrier ring 3 on each side of the projections 18. The grooves for the pad ribs are formed between the latter. The discs 22 (not shown) are located between webs 35 and have recesses in the inner edges to permit them to pass over the webs 35 when mounting the parts.

Title: Improvements in or relating to an apparatus for measuring and recording variations in the weight and dimensions of materials with temperature
IPC: G01N5/04
Filed: 1967-07-03
Abstract: 1,123,519. Measuring electrically. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 3, 1967 [July 4, 1966], No.30627/67. Heading G1N. The changes in weight and in one dimension of a specimen E, e.g. of concrete, with temperature are measured by suspending the specimen from one arm of a balance in a furnace and simultaneously measuring the dimension with a differential dilatometer. The specimen is suspended, in a pan 4, from one arm of a balance 1, which, if a change in weight occurs, is automatically re-equilibrated by operation of a motor 12, energized by the output of a photo-resistive transducer 10, via relay B. Energization of the motor increases or decreases the length of a tie 15a suspended between the other end 1a of the balance beam and the shaft of the motor. Rotation of the motor 12 also alters the value of a variable inductance 14, via a cam 15, which transmits a signal indicative of the change in weight of the specimen to a recorder 17 via a demodulator 16. Simultaneously the dimension of the specimen is measured by a system comprising a fixed rod 7 and a rod 8 held against the side of the specimen, the two ends of the rods being connected to a variable inductance 9 which also transmits a signal, indicative of changes in the dimension of specimen, via demodulator 16 to the recorder 17. The temperature of the furnace is measured by a chrome-alumel thermocouple 29 whose output is also recorded at 17, and is controlled using thermocouple 30 connected to a programme cam 19 and regulator 20. If required the temperature of the furnace may be held constant once a change in weight has occurred. To this end a photo-resistive transducer 11 is provided to detect unbalance of the beam 1 and when this occurs to transmit a signal via a time delay relay 18 to stop rotation of the cam 19 and thus to maintain the temperature constant. If it is desired to analyse the gases given off by the specimen a scavenging gas may be blown through the furnace via conduits 26.

In a steam boiler comprising a first naturalcirculation section constituted by tubes 8, 9, 10, 11 which line the wall of the furnace 5 and extend from the lower water headers 12, 13, 14, 15 to an upper steam-and-water drum 6, and a second convection-heated forced-flow section 19 with circulating pump 20 in a downcomer 21, the flow of water through the first section is augmented, e.g. at starting up, by opening a pipe connection 24 between the said pump and water headers. The adjacent ends of the water headers are jointed by union pipes 17 of slightly smaller diameter, and branches 25 from the pipe 24 open into these unions ; preferably the branches 25 terminate in nozzles 26, Fig. 5, each directed to discharge axially into a header, or, alternatively, the branches are extended axially through the headers and are provided with side nozzles projecting into the inlet ends of the wall tubes 8 ... 11. The downcomers 16 of the first section open into the unions 17 at the two ends of the header 12 or into the midportions of the opposed headers 13, 15. In a modification the downcomer 21 is dispensed with, the inlet of the pump 20 being connected to the header 12 and its outlet to the pipes 23, 24, as before, with the pipe 24 leading to the header 14. In a further modification the first section has a separate circulating pump located in a circuit from the downcomer 16 to the headers 12... 15.
