Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B33/00
Filed: 1950-06-16
Abstract: 674,289. Refrigerating. ELECTROLUX, Ltd. June 16, 1950 [June 28, 1949; June 28, 1949; June 28, 1949]. No. 15063/50. Class 29. In an absorption refrigerating system of the continuous cycle inert gas type in which absorption liquid is raised in the vapour expulsion unit by a vapour lift pump, the liquid raised by the pump is divided into two streams one of which returns to the suction side of the pump and the other of which is supplied to the absorber. In Fig. 1, strong solution flows through the inner path 154 of liquid-heat exchanger 131 and enters an analysing conduit 133 at a point 134. Solution flows from the: bottom of conduit 133 to vapour lift pump 135 the top of which is closed and is formed with two lateral openings 141, 140, the former leading solution to the boiler 111 through a pipe 143, and the latter leading solution through a pipe 148 to enter the analysing conduit at a point 146. Vapours expelled in the boiler flow through pipe 143, openings 141, 140 and pipe 148 to the analyser. Alternatively, the vapours may pass from pipe 143 to pipe 148 through a pipe byepassing the openings. In Fig. 3, the liquid heat-exchanger is formed with an outer rectifying jacket 572 and the system contains a corrosion inhibiting substance. In order that this substance may reach the rectifier jacket the latter is also traversed by strong solution divided from the main solution flow path. The upper end of the vapour lift pump 535 is closed and has lateral openings 541, 540, the former leading solution by a pipe 543 to the boiler 511 and the latter leading solution by a pipe 571 to the jacket 572, whence it flows through a U-tube 577 welded to the flue to pump the solution into an analysing conduit 533. Vapours expelled in the boiler flow through a pipe 545 to enter the analyser at a point 546. They then flow through a pipe 570, the pipe 571, the rectifier jacket 572 and a pipe 574 to the condenser.

Title: Improvements in or relating to follow-up control systems for the remote operation ofa stage lighting installation or similar installations
IPC: H05B37/02
Filed: 1952-06-16
Abstract: 711,195. Control systems for stage lighting. SIEMENS - SCHUCKERTWERKE AKT.-GES. June 16, 1952 [June 15, 1951], No. 15154/52. Addition to 700.909. Class 38(4) [Also in Group XXXVIII] The parent Specification is modified by using electromagnetic clutches to transmit power from continuously running motors for driving the variable tap on the lighting transformer regulator. The system employs two continuously running motors. one running fast and the other slow. and each driving two shafts rotating in opposite directions. In the embodiment shown if the slider on the transmitter or command potentiometer 1 is moved over a wide range to produce coarse adjustment of tap 5 on stage lighting transformer regulator 3 the voltage between 1 and reference potentiometer 2 operates a non- polarized relay 7 in addition to polarized relay 6 whereby clutch 19 or 20 is operated to couple the corresponding fastrunning shaft to the tap 5. The latter is ganged to the slider on the reference potentiometer 2 and when the voltage between 1 and 2 has decreased sufficiently relay 7 falls back and the movement of tap 5 is continued slowly via clutch 17 or 18 and the corresponding slow-running shaft until the voltage between 1 and 2 reaches zero de-energizing relay 6. If the slider on 1 is moved over a narrow range to produce fine adjustment only of tap 5 the voltage between 1 and 2 is insufficient to operate relay 7 and thus tap 5 is moved slowly through a clutch 17 or 18.

Title: A process for the manufacture of improved false-twist-crimped bulked filament yarn
Inventor: NAVA MARIO
IPC: D02G1/02
Filed: 1958-05-13
Abstract: 921,583. Spinning and finishing yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 7, 1959 [May 13, 1958], No. 15240/58. Class 120 (3). A torqueless, twist e.g. false-twist, crimped, bulked yarn of synthetic filaments has crimp elongation less than 15% and shrinkage per unit length in hot water or steam of less than 10%. (Crimp elongation is measured by first applying a load of 0.0033 grams/ denier, to straighten the yarn so that its original length can be measured, then adding a load of 0.04 grams/denier and determining the extension, with crimp pulled out, which results). The basic yarn is textured by twisting e.g. 10-170 turns/ inch, setting the twist e.g. by heating, untwisting the yarn, winding the resultant crimped yarn on to a package by feeding it thereto at a speed higher than the wind-up speed, and then subjecting the yarn (which may remain on the package) to a hot fluid or gaseous treatment e.g. in a steam oven, which may form part of a dyeing process. The filaments may be polyamide, polyester, polyacrylonitrile or polypropylene. The first heat-setting may be effected by electrically or fluid heated tubes or curved or straight contact plates or elements, hot fluids, or infra-red heating, and may be insufficient to render the crimp permanent (such permanence being ensured by the fluid or gaseous treatment). In the apparatus shown, which corresponds to the apparatus of Specification 881,729 with means (not shown) for subjecting the yarn to the hot fluid or gaseous treatment, yarn 1 is fed through a heater 2 and a false-twister 3, with predetermined speed differential or equality between feed and withdrawal, by feed and take-up roll systems 4 and 5, thence to traverse mechanism 7 which lays it on package 8 driven by roller 9 at a 10-30% lower speed than that of system 5.
