Title: Improvements in or relating to the evacuation and sealing of bottles, jars, and other containers
IPC: B67B3/24
Filed: 1922-09-15
Abstract: 208,237. Poole, H. J. Sept. 15, 1922. Stoppering.-In sealing bottles, tins, jars, &c., having liquid or partly liquid contents such as sterilized milk or fresh fruit in syrup or water, a sealing vacuum is produced within the bottle &c. by placing the lid or seating cap or stopper against a luting ring while the bottle &c. is submerged in liquid of the same character as its liquid contents and extracting a portion of the liquid contents during the submersion. A handpump may be applied to produce a vacuum within the container by exhausting a small part of its liquid contents, the sealing-cap being such as automatically lifts during evacuation, substantially as described in Specifications 164,214 and 188,016, and upon the pump vacuum being broken being automatically forced upon its seat by a spring &c. which may be part of the pump structure. As shown, the mouth of the bottle A has an inside ledge B forming a seat for an india-rubber luting ring C upon which the stopper or cap D is forced so as to compress the ring and express a small quantity of the contents of the bottle through a vent, which may be provided by inserting a pin E between the edge of the cap D and the ring C. The ring is compressed by a block F<1> pivoted to a lever F fulcrummed upon a bracket G carried by a hinged ring H adapted to encircle the neck of the. bottle. By means of handles I, the ring H is held tight by one hand around the neck of the bottle while the lever F is actuated bv the other hand. Instead of using a pin E, the cap D, Fig. 2, may have a central conical aperture for the reception of a conical plug J and the block F<1> may carry a spring-pressed plunger K so that when the ring C is compressed the pressure developed within the bottle forces the plug J outwards against the spring J<1> and permits the. liquid to be expressed from the bottle. On releasing the lever F, the vacuum within the bottle holds the cap D sealed against the ring C and pulls the plug J into its seating. After producing a vacuum within the container, the lid or sealing cap may be released while the container is submerged and be secured by a spring clip or other suitable, means.

Title: Servo-actuator
IPC: G05D23/19
Filed: 1967-06-01
Abstract: 1,153,258. Fluid-pressure actuators. DANFOSS A. S. June 1, 1967 [July 2, 1966], No.25239/67. Heading F1P. [Also in Division H1] A servo-actuator includes a piston 6 controlled in use by a pressure fluid 3 so that when the pressure of the fluid 3 decreases on actuating member 11 mounted on piston 6 actuates an on-off switching device connected in a circuit controlling the pressure of fluid, the actuating member 11 being mounted on piston 6 by means of a lost-motion coupling 13 and being adapted for movement between two fixed stops. The switching device may be an electron switch (as shown) or a valve, and coupling 13 is a friction coupling. As shown switch 19 is closed completing the circuit through coil 4 which heats up, causing fluid 3 to expand, pushing piston 6 to the right until the desired position of piston end 7 is reached when switch 19 is opened. During the movement of piston 6 to the right, lever 11 pivoted at 12 and carrying movable contact 14 has moved to the right until it abuts stop 16 where it remains. When switch 19 is opened, coil 4 cools down, fluid 3 contracts and spring 9 pushes piston 6 to the left which causes lever 11 to move until contact 14 abuts fixed contact 15, again completing the circuit through coil 4 which again heats up and moves piston 6 to the right until contacts 14, 15 break when again the circuit through coil 4 is broken, so that piston 6 oscillates a small extent about the desired piston position, thus maintaining it substantially constant. Instead of lever 11, there may be a movable friction collar situated between two fixed stops and acting on the movable contact of a switch coil 4 may be the energizing coil of a magnetic valve supplying compressed air to cavity 2 instead of the cavity 2 containing a heated expanding fluid, with a throttle to prevent the piston moving too fast and a relief aperture to allow it to return. The three switching devices may also be three valves.

Abstract: 1312188 Stapling fibres SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA 19 April 1971 [26 March 1970] 25364/71 Heading D1F In a method of continuously cutting a flattened tow of continuous filaments into staple fibres, the tow is fed at constant speed past a station whereat the filaments are thermally sheared by a pulsed laser beam. The latter is focussed to provide a rectangular beam having in the plane of the cutting station a crosssection with a major side greater than the width of the tow and a minor side of a few microns. The time interval between successive pulses of the beam corresponds to the time taken to advance the tow by an amount equal to a predtermined fibre length and the pulse duration is less than one thousandth of a second. The laser has a wavelength corresponding to that of a main absorption band of the material, e.g. nylon or polyester, of the filaments. As shown, a tow 18 is fed between counter-rotating, endless chain tracks 20 and 22, in the form of metal or non-metallic bands, guided by pulleys 24, 26 and 28, 30, at least one of each pair of which is driven. Track 20 is formed with rectangular windows 32 spaced uniformly therealong at intervals equal to the highest common factor of all the lengths of staple fibre into which the filaments may be required to be cut. A laser beam pulse 14, emanating from a generator 10, which may cooperate with interruptor means, e.g. an apertured rotating disc (not shown) and emerging through a window 12, passes through aligned windows 32 to sever the tow. Slit nozzles 36, 38, emit jets of inert gas, such as compressed nitrogen, against the tow above and below the zone where the laser strikes, to ensure immediate dispersal of heat and to prevent oxidation. Excess laser beam energy may be absorbed by track section 22 or this may also comprise windows (not shown) through which the laser passes to a cooled screen.
