Title: Improvements relating to liquid flow control valves
IPC: F16K31/26
Filed: 1966-01-21
Abstract: 1,068,445. Valves. C. C. FOGG, and E. J. BROWN. Jan. 21, 1966 [Jan. 22, 1965], No. 2907/66. Heading F2V. [Also in Division G3] A valve body is formed by two parts 5, 7 which are connected by bayonet means, the part 7 has an inlet tube 11 upon the discharge end of which slides a closure member 15 controlling flow through a number of outlets 22. Communication between the tube 11 and outlets takes place via a port 20 through the member 15, which port 20 coacts with a rubber-faced piston 27 slidable in body part 5. A stem 30 from the piston 27 co-operates with a lever pivoted to a float arm a; the lever and float arm may be replaced by a manually-adjustable abutment. When the float falls or the abutment is displaced away from the stem 30 the pressure in the inlet tube 11 causes retraction of the piston 27 to open port 20 whereupon the pressure builds-up in a chamber 12 until it withdraws the closure member 15 to open the outlets 22. Upon the float rising or on repositioning the abutment the piston 27 protrudes into the chamber 12 to restrict the flow therethrough so that the pressure differential across the closure member 15 is sufficient to move it into engagement with the piston 27 and close the ports 20, 22.

Patent GB-470331-A (GB)
Title: Improvements relating to the manufacture of material and articles from resinous substances
Filed: 1936-01-31
Abstract: A composite material comprising a substance capable of being hardened or set, reinforced with a non-metallic fibrous or filamentary material in felted, corded, or woven condition, is produced by imparting to the reinforcement a substantially permanent predetermined tension either during or after the manufacture of the composite material, the tension being equal to or greater than the maximum tensile stress to which the material is intended to be subjected during use.  The setting substance may comprise natural or artificial resins, cellulose esters, and similar products.  In an example, a cotton or artificial silk fabric is impregnated with a phenol-formaldehyde resin dissolved in methylated spirits or acetone by being drawn through a bath over suitable rollers.  The impregnated fabric is then dried and stretched on a frame having one or more movable sides to which a load is applied by means of weights or turnbuckles.  A stress of 2,000 lb. per sq. inch or more is applied to the fabric and is maintained while the fabric is pressed between hot plates to harden the resin.  When using a thermo-plastic substance such as cellulose acetate or an acrylic ester, the material is heated to soften it and the tensile stress is maintained until the material has once more cooled below the softening point.  In some cases, the tension may be imparted to the reinforcement by twisting it or by working the composite material while plastic.  Tensile stresses of varying amount may be applied to different parts of the reinforcement or in different directions.  The reinforcement may be of paper or felt as well as fabric or strands.ALSO:A composite material comprising chlorinated rubber or other substance capable of being hardened or set reinforced with a non-metallic fibrous or filamentary material in felted, corded, or woven condition, is produced by imparting to the reinforcement a substantially permanent predetermined tension either during or after the manufacture of the composite material, the tension being equal to or greater than the maximum tensile stress to which the material is intended to be subjected during use.

Title: Improvements in methods of and apparatus for determining distances by means of reflected sound waves
IPC: G01S15/10
Filed: 1922-02-04
Abstract: 200,123. Baron, H., (Signal Ges.). Feb. 4,1922. Determining distances acoustically.-Relates to means for determining depths and distances in which an echo is timed by comparison with a delayed action of the initial sound, and comprises the use as a delaying device of a record such as a telegraphone or gramophone record, simultaneity being tested by the binaural directional effect or by optical or photographic methods. In the device shown in Fig. 1, the direct sound affects a microphone 14 which, through a coil 22, makes a record on the wire 23 of a Poulsen telegraph one. The detector 14' is shielded by the casing 21' from the direct sound, but communicates the echo to a receiver 15'. The distance between the recording and reproducing coils 22, 22', of the telegraphone is adjusted until the sound reproduced in the earpiece 15 co-incides with that in the earpiece 15<1> due to the echo. The distance travelled by the echo can thus be found when the speed of travel of the telegraph one wire is known. In a modification, the screen 21<1> may be abolished and an electric switch associated with electric striking mechanism may break the circuit of the receiver 15<1> at the moment of striking; and in a further modification this switch mav also break the telegraphone circuit as soon as the stroke is over. In the device shown in Fig. 4, the same (magnetic) instrument 1 is used for emitting the initial sound and for detecting the echo. The instrument 1 is connected through contacts on a revolving cylinder 33, first to a source 2 of alternating current, whereupon a sound is emitted and the coil 23 makes a record on a gramophone disc 37 ; and thereafter to an earpiece 15<1> for observing the echo, the coils 22, 22', serving the same purpose as in Fig. 1. In a modification, the alternator 2 may be replaced by a vibrating-plate device constructed similarly to the instrument 1, the gramophone disc being replaced by a telegraphone, and the revolving switch 33 by a multispring switch operated by the striking mechanism and adapted to connect the instrument 1 either through an amplifier to the receiver 15', the recording coil 22 being meanwhile short-circuited : or through the recording coil 22 to the vibrating plate device.

Title: Garment press
IPC: D06F71/40
Filed: 1944-02-24
Abstract: 590,775. Ironing presses. WILLIAMS, W. P. (American Laundry Machinery Co.). Feb. 24, 1944, No. 3483. [Class 138 (ii)] An ironing press has a work clamp which is engaged manually to secure the work to the buck whilst arranging it, and is released automatically when the head is swung over the buck but before the buck has closed up to the head. The work is then free to be removed immediately the buck and head are separated. The invention is shown applied to a fluidpressure operated shirt sleeve press having two bucks 10 arranged end to end to take the two sleeves with the body of the shirt lying in the gap between them. The bucks are wider than any sleeve, and their inner ends are inclined so that sleeves of varying length can be exactly accomodated by moving them transversely of the bucks. Whilst arranging the sleeves, the cuffs are secured to the ends of the bucks by pivoted clamps 27 which are biassed to their two alternative positions by springs 31, are adapted to be closed manually, and released by servomotors 34 operating through tappet levers 36. In operation, the cuffs are first secured under the clamps 27 and the sleeve arranged over the bucks. Valves 19 and 20 are then operated to admit pressure fluid to a motor 18 which straightens a toggle 17 to swing the head 15 over the buck. As toggle 17 straightens, it also opens a valve 21 to admit fluid to a main motor 14 which lifts the bucks into pressing engagement with the head. The valve 21 also admits fluid to the servomotors 34 which thereupon actuate their tappet levers 36 to release the clamps. This latter action is complete before the press has fully closed, since the pipe connection 38a of the servomotors 34 to the valve 21 is shorter than that 38 of the main motor 14. To open the press, a valve 22 in connection 38 is momentarily actuated to cut off the fluid from motor 14. Springs restore the various parts and open the press, and the shirt is free for immediate removal.
