Abstract: 1,158,425. Temperature responsive actuating elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 21, 1966 [Oct. 25, 1965], No. 45097/65. Heading G1D. [ Also in Division D1] A washing machine water inlet control comprises a thermo-responsive capsule 2 containing a heat expansible wax 3 which controls an actuating member 4 coupled to inlet valve 10 which is opened when capsule 2 is heated by an electric heater 17 and closed either by de-energization of the heater 17 and if necessary subsequent cooling by the admitted water of capsule 2 or only by cooling by the admitted water. The capsule 2 which is mounted in the washing machine tubs contains rubbery material 3' surrounded by the wax 3. Member 4 extends through an O-ring seal 8 into valve chamber 9 and carries valve 10 which closes a port between inlet port 11 and port 12 leading to the tub. Valve 10 is biased closed by spring 6 engaging seal 8 and a collar 22 on member 4 which may also engage the actuating arm 21 of a micro switch 19. In operation, a switch (18, Fig. 3, not shown), is closed to energize the heater 17 and valve 10 is opened. When the tub has filled to level Z switch (18) is opened and the tub fills to level Y while capsule 2 is cooling and if switch 18 fails to open the valve will still be closed by the cooling of the capsule. If switch 19 is provided, switch (18) may open after the initial opening of valve 10 and switch 19 will maintain the heater energized until the capsule 3 is cooled by the incoming water.

Title: Improvements relating to the production of granular fertilizers
IPC: C05B5/00
Filed: 1962-11-29
Abstract: A fertilizer is made by mixing ground basic slag, e.g. Thomas phosphate slag, with up to 10% of its weight of a water-soluble crystalline salt, wetting the mixture, granulating and drying in a gas containing sufficient carbon dioxide to react with the lime present in the slag to form calcium carbonate, which binds the particles together within the grains.  The salt may be a potassium salt or rock salt. The granules may be dried in gas at at least 100 DEG C. and obtained by burning blast-furnace gas, producer gas, coke-oven gas or natural gas.

Abstract: 1,185,067. Parallax panoramagrams. EASTMAN KODAK CO. Oct. 5, 1967 [Oct. 6, 1966], No. 45496/67. Headings G2J and G2M. In the manufacture of parallax panoramagram pictures, a method of aligning a printing plate bearing a lineiform image with the lenticules of an embossed transparent plastics coating for the print comprises making a reference print with lines parallel to the lenticule-forming grooves of the embossing roller, making a test print from the printing plate on to the reference print and thus adjusting the position of the printing plate as indicated by the Moire pattern on the test print. The reference prints may be made by means of carbon paper between the embossing roller and a sheet of paper. Again, the reference prints may be taken from a printing plate bearing a number of slightly converging groups of parallel lines. The printing plate is prepared by successively exposing a photographic plate to a grating transparency two feet long and half an inch wide ruled at 150 lines per inch lengthwise. The grating is rotated against a control grating through a precise small angle as indicated by the Moire pattern before each exposure. Sheets printed from this plate are then coated and embossed by the roller, the plate being adjusted to give parallelism with the correct group of lines. In another technique, the grating printing plate comprises lines of a different spacing to that of the lineiform image. In preparing a collage of say 16 pictures, a large print of the convergent grating is made and covered by transparent sheeting. Sixteen identical gratings are made on stripping film and are transferred to the transparent sheet after alignment with the grating thereon. The 16 lineiform images may now be aligned with the 16 gratings and transferred to a further sheet.

Agglomerates of alumina were made by adding to a suspension of Al 2 O 3  in chloroform as the first liquid a solution of HNO 3  containing aluminium nitrate in water as the second liquid and stirring the mixture for 6 hours, after standing at room temperature for 5 days agglomerates of Al 2 O 3  were separated by decantation and drying.

Title: Elastic waves device for memorizing information

Filed: 1975-11-05
Abstract: 1516400 Electro-acoustic memorizing devices THOMSON-CSF 5 Nov 1975 [8 Nov 1974] 45974/75 Heading H3U In a memory device, acoustic waves corresponding to the information to be memorized are emitted by a transducer on a substrate and a first electromagnetic pulse is then applied to the substrate to produce a time-independent spatial pattern which is then fixed; the pattern is subsequently read by applying to the substrate a second electromagnetic pulse which interacts with the pattern to produce second acoustic waves which propagate back to the transducer. A plurality of independently-operating transducers may be provided. A surface wave device, Fig. 1, comprises interdigital transducers 5 on a piezoelectric substrate I and an electrical charge pattern is fixed by a composite layer 4 employing ferroelectric or magnetoelastic phenomena, or employing the modification of charge carrier population in a semiconductor. Alternatively the pattern may be memorized by the substrate itself. The electromagnetic pulses are applied by electrodes 2, 3. On their way back to the transducer the second acoustic waves may be "re-frozen" by a third acoustic wave, and subsequently again "unfrozen" by a fourth acoustic wave. To avoid interference between the signals corresponding to the different transducers 5, the transducers may have non-rectilinear teeth (Fig. 4 not shown). Similarly in a bulk wave device, Fig. 6, transducer 50 may be irregularly shaped, i.e. non-planar; in this embodiment a three-dimensional pattern is produced by applying an electromagnetic pulse to electrodes 20, 30.

Abstract: 1,090,023. Steadying devices. K.L. ALLINSON. Nov. 10, 1965 [Nov 11, 1964], No. 46023/64. Heading G2A. A steadying device for a hand-held camera or other optical equipment comprises a spool having two discs 1, 2 connected by a hub portion. Rotatably mounted on this hub is an inner spool comprising discs 5, 6 connected by a hollow shaft 7. Disc 1 carries a threaded rod 3 suitable for screwing into the tripod bush of a camera. One end of a length of cord 8 is secured to shaft 7. Slidable over this assembly is an outer ring (9, Fig. 4, not shown) having a peripheral slot (11). The other end of the cord 8 passes through this slot. When not in use, the cord is wound on spool 5, 6, 7 which is enclosed in ring (9), and the device may still be left attached to the camera for convenience. When required for use, ring (9) is pulled off the spool assembly and allowed to fall, the cord unwinding accordingly. When fully unwound, it reaches to the ground. The camera operator may then place his foot on the ring and draw the cord taut, so tending to minimize camera movement.
