Abstract: 575,502. Pumps. AKTIEBOLAGET GOTAVERKEN. Aug. 17, 1944, No. 15766. Convention date, May 7, 1943. [Classes 7 (ii) and 7 (vi)] In an engine charged by a pump driven by an exhaust-actuated turbine, exhaust gases at a pressure higher than the final pressure in the engine cylinders are supplied to the turbine with an adjustable amount of high-pressure air, in addition to the normal exhaust gas supply. A charging compressor 4 is driven by an exhaustactuated turbine 3 which, in addition to being supplied with exhaust gas through a conduit 5, is supplied with high-pressure gas from a conduit 7, high-pressure air being added through pipes 18 from a reciprocating compressor 21. The pipes 18 are connected near the exhaust valves which are thereby cooled. This cooling may be improved by passing the air through a jacket round the valve stems. If the high-pressure exhaust is supplied from piston-controlled ports, double-seated poppet valves may also be provided. The supply of air is controlled by a spring-loaded piston 22, Fig. 3, the air arriving by a pipe 26. The loading is adjustable by rotation of a hand wheel 24. As the pressure increases, delivery pipes 20, 19, leading to the turbine nozzles, and 17 leading to the exhaust conduit 7, are opened in succession. The air supply pipe 15 for the pump 21 may be connected through a cooler 16 to the engine admission conduit 13, or to atmosphere. The pump 21 may be replaced by a rotary compressor, but instead air under pressure may be supplied independently of the engine.

Abstract: 1,135,825. Skein winding, swift, stop motion. DOBBIE INDUSTRIES Ltd. 12 April, 1966 [18 May, 1965], No. 16029/66. Headings DID and D1J. A method of skein dyeing yarn comprises winding a predetermined amount of the yarn onto a skein on a collapsible reel 14, see Fig. 1; guiding the yarn transversely of the reel, e.g. with traverse 12, so as to form a skein of constant depth across the reel, stopping the winding and collapsing the reel, removing the yarn as a skein, mounting the skein on a stationary swift, see Fig. 10, and winding the yarn from the stationary swift into a package, see Fig. 12 (not shown). The skein winder has a driven guide roll 12 which has slots 100, 102 arranged so that the rate of traverse of the yarn increases at the extremities of its travel, thus resulting in a constant depth skein even at its edges. The grooves are of different depths and have champhered sides, see Figs. 3, 4 and 5, not shown. The reel 18 can be collapsed by operation of double acting pneumatic unit 70 through air lines (76), (78), see Fig. 2, not shown. The yarn can be wound at 600-1500 yds/min to form a skein 10-40" wide and weighing up to 12 lbs. The stationary swift, Fig. 10 has non-rotating skein support arms 170 and a removable free floating wheel 220. In use the wheel is removed and the arms collapsed, as shown. The skein 200 is then loosely placed over the arms. The wheel is then remounted and the arms expanded pneumatically, see Fig. 11, not shown. The yarn is withdrawn over-end over the rotating wheel In the package winder, Fig. 12 the yarn passes behind pulley 400, over pivoting pulley 406; around pulleys 400 and 406 again, around grooved drive pulleys 360, 362 to provide two complete loops separated by wire 388, under guide pulley 412 and slack take-up device 414, past tension-sensing arm 432, over guide roll 340 and onto the bobbin 354 see also Fig. 13, not shown. Excess tension in the yarn as it passes over pivoting pulley 406 or insufficient tension in the yarn at arm 432 will cause the driving electric motor to be stopped.

Abstract: 930,248. Balanced flue outlets. GAS COUNCIL. April 27, 1962 [May 3, 1961], No. 16076/61. Class 25. In a balanced flue terminal in which the combustion products outlet 20 and the air inlet 30 terminate in a box-like chamber adapted to be built into a wall with its open or front end 15 substantially flush with the wall face, the combustion product outlet is in the form of a tapering passage 33 in the upper part of the chamber projecting towards but terminating short of the open end of the chamber, beyond the air inlet 30 which opens from the lower part of the chamber in or near the rear wall thereof. The tapering passage 33 is formed between a horizontal plate 22 and an inclined plate 23, both extending across the full width of the chamber. The open front of the chamber is protected by a grill 15 consisting of a number of horizontal bars 36 and a vertical central bar 37. To minimize the effects of glancing winds, a vertical baffle 19 extends rearwardly from the grill 15 in the lower part of the chamber to at least half the depth of the chamber, thus dividing this portion of the chamber into two and a horizontal baffle is arranged to extend across the full width of the chamber just above the vertical baffle and to extend rearwardly from the grill 15 for at least a quarter of the depth of the chamber. The top of the grill 15 also constitutes a horizontal baffle 38 which as well as reducing the effect of glancing winds also helps prevent the ingress of rain into the chamber.

[Class 40 (iv)] [See also Group XL] In duplex telephony or duplex A.C. or D.C. telegraphy employing a Wheatstone bridge, the artificial line does not match the natural line, and the mismatch is compensated by combining in the receiver the effects of voltages differing in phase and derived from a number of points in the artificial line. In this way the receiving diagonal is dissociated from the transmitting diagonal for all the Fourier components of a signal, Thus an artificial line b, comprising resistance and capacity only may be used with a cable I loaded with distributed inductance, and the unbalance currents in the receiving diagonal A are neutralized by means of currents derived from points D, E, F, of the artificial line through amplifiers M, N, P. These compensating currents are applied to separate coils in the relay Q in such a sense as to neutralize the current derived from the diagonal A. The resistance of each section of the artificial line is made proportional to the wave-length of the component to be collected from that section. The relay Q can be replaced, by means of a multipole switch, by a test set, Fig. 2 (not shown), so that the effects of the components can be observed separately and in combination. In practice the amplifier A comprises resistancecoupled valves fed through altering devices consisting of condensers and rejector circuits shunted by resistance and through a transformer primary of which is shunted by resistance and inductance while its secondary is shunted by resistance, Fig. 3 (not shown).
