Title: Improvements relating to automatic feed devices for liquids
IPC: F22D5/24
Filed: 1930-03-22
Abstract: 348,302. Feedwater supply apparatus. WEERTS, V., 104, Rue de Pepinster, Ensival, Belgium. March 22, 1930, No. 9244. Convention date, March 23, 1929. [Class 123 (ii).] The admission of steam under pressure to discharge feedwater from a tank 2 is regulated by a valve 4a controlled by an electromagnet 5 the circuit of which includes gaps 110c, 110d, 111c, adapted to be closed by the water and to operate the electromagnet by means of a starting relay 10d to open the valve and a holding relay 10c to keep it open when the water level falls. Feed enters the tank through a pipe 3 the steam admission valve 4a being closed. When the level rises above the gap 111c a stop relay 11c opens a switch 11 in the circuit of an electromagnet 8 operating a steam discharge valve which accordingly closes. When the gap 110d is sufficiently immersed the starting relay 10d causes a contact bridge 10d to complete the circuit of the electromagnet 5 to open the valve 4a. After some time the circuit of the electromagnet 8 is broken at a second point by switch 10. After the water level sinks below the gap 110d, the electromagnet 5 is maintained energized by means of the holding relay 10c until the gap 110c is uncovered, whereupon valve 4a is closed and valve 7a opened.

Title: Improvements in or relating to explosively actuated fastener driving power tools
IPC: B25C1/10
Filed: 1966-03-03
Abstract: 1,141,722. Cartridge-actuated tool. ETABLISSEMENT DE TECHNIQUES MODERNES. 3 March 1966 [8 March 1965; 9 Aug., 1965], No. 9269/66. Heading B4C. A cartridge - actuated tool for driving fasteners into hard material comprises a piston 21 reciprocable in a barrel 4 and a guide piece 15 capable of being displaced relative to the axis of the piston so that access is provided to the rear end of the guide piece for the introduction of the fastener. The piston 21 is provided with an end portion 21a slidable in the barrel 4 which is pivotable about a pivot 8 carried by a handle portion 1, 2 containing the breech mechanism. A driver portion 21b of the piston is separated from the portion 21d by a collar 21c which is slidable in a socket 10 connected to the barrel. The guide piece 15 is slidable within slots 11 formed in the socket and is also guided by means of a rod 13 secured to the barrel. In order to load the tool with both a fastener and a cartridge the guide piece is moved forwardly against the action of a spring 20 and rotated about the rod 13 and the barrel is pivoted about the pivot 8; the guide piece may be in the form of a cross in order to hold four fasteners. In the modification shown in Fig. 9, the guide piece 35 is connected to a slide member 33 via a ball-and-socket joint 34, the slide member being reciprocable in a guide socket 28 secured to the barrel 24 by means of a split nut 38a, 38b; a shock absorber 39 is mounted between the barrel and the nut. The guide piece 35 is maintained in the position shown by means of a reciprocable sleeve 36. In order to load the tool with a fastener, the sleeve is moved rearwardly so that the guide piece can be rotated at right-angles to the axis of the piston thereby providing access for the insertion of a fastener. The cartridge is loaded into the barrel by pivoting the latter about a pivot 26. In the event of overtravel of the piston, an enlarged portion 29a thereon strikes the slide member so that a flange 33b thereon engages a boss 28a on the socket thereby causing the shock absorber 20 to be compressed. Further overtravel is retarted by the impact of the portion 29a on the slide member causing the flange 33b to override the boss 28a until the portion 29a itself contacts the boss. In both the embodiments shown the spent cartridge is ejected by moving the piston rearwardly so that the end portion 21a strikes the cartridge.

Title: Wet spinning artificial filaments
IPC: D01D5/12
Filed: 1961-03-15
Abstract: 976,336. Wet spinning artificial filaments. CELANESE CORPORATION OF AMERICA. March 15, 1961 [March 21, 1960], No. 9427/61. Heading B5B. In the production of artificial filaments, particularly cellulose triacetate filaments, by extruding a solution of a filament-forming material through a multiholed spinneret into a liquid coagulant having a swelling effect on the material and stretching the filaments formed during their passage through the coagulant, there is applied to the bundle of filaments leaving the coagulant a tension which is continuously or from time to time measured and maintained within a range predetermined to yield a product having a " tensile factor " approximately or actually the maximum possible under the spinning conditions. The " tensile factor " is defined as the product of the tenacity in grams per denier and the square root of the percentage elongation at break. The spinneret may have more than 1000 orifices and the tension applied to the bundle of filaments leaving the coagulant may be maintained within the range of 160 to 300 milligrams per filament. Before applying the tension the proportion of adherent coagulant carried by the filaments may be reduced to about 250% of the weight of the filaments, e.g. by friction applied by a member controlling the tension, or more coagulant may thereafter be squeezed from the filament by means of pairs of squeeze rolls to further reduce the proportion carried by them to between 100 and 200% by weight of the filaments. Coagulant may thereafter be evaporated from the filaments while they are in a tensionless condition. As shown in Fig. 1, the spinning solution is extruded through the spinneret 12 in the spin pot 11 into coagulant supplied to spin pot 11 through a sparger 14 supporting glass balls 16 which smooth out the flow of coagulant. From the spin pot the freshly formed filaments 17 and coagulant travel up the spinning column 18 and spent coagulant overflows into the head-box 19 from which it drains away through outlet 20. The filament bundle 17 passes first over a saddle guide 21 (Figs. 1 and 2), then over pins 22 to 24 and a tensiometer 25. The filament bundle 17, along with one or more similar bundles 26 from adjacent spinning positions, then passes successively between squeeze roll pairs 27-28, 29-30, 31-32 and 33-34. The filament tow leaving the roll pair 33-34 passes through air jet 35 where it is opened and partially dried and then passes through oven 36 where drying is completed in tensionless state. Finally the filaments are cut into staple fibre 38 by centrifugal cutter 37. Pins 22 to 24 and saddle guide 21 are adjustably mounted in the slots 40 of a plate 41 hinged at 42 to the wall of head-box 19 and held by spring clip 43. Specification 881,856 is referred to.

Abstract: 1,013,689. Power hammers. SCOVILL MANUFACTURING CO. March 13, 1963 [March 13, 1962], No. 9593/62. Heading B3H. [Also in Division F1] An impact air cylinder having a piston 19 for operating a press punch 28 connected thereto, comprises an upper cylinder 12 separated from a lower cylinder 13 by a central plate 11 provided with first and second non-return valves 21, 23 and having an aperture 24 containing a sealing ring 26 which engages an extension 25 of the piston 19 when in its upper position in the lower cylinder. In operation pressure air is supplied through an inlet duct 16 to the upper chamber 12 to act on the extension 25 and when a sufficient pressure is built up in the chamber 12 the piston 19 moves downwardly and the extension 25 descends below the sealing ring 26 so that the whole surface of the piston 19 is suddenly exposed to the air pressure and the piston thereby continues downwardly at increased speed. The first non-return valve 21 allows atmospheric air to enter the space between the central plate 11 and the piston 19 in order to prevent a vacuum forming therein. The piston 19 is cushioned at the end of the downward stroke by a boss 31 thereon coacting with a chamber 30 through which air in the lower cylinder passes to an outlet duct 18. A multi-way control valve (not shown) is operated to return the piston, whereby air is supplied through the duct 18 and exhausted through the duct 16, the second non-return valve 23 preventing air from being trapped between the central plate 11 and the piston 19.
