Abstract: 819,725. Knitted fabrics. GROVE SILK CO. Nov. 16, 1955 [Feb. 10, 1955], No. 32740/55. Addition to 781,030. Class 74 (2). [Also in Group IX] A stretchable knitted fabric is produced by forming successive bands (e.g. knitted courses or groups thereof) from three dead yarns of which two are of microcrystalline polymer material and have a potential ability to twist in opposite directions to each other, which ability is activated, after fabric formation, by a set-releasing, treatment. The third yarn, which has no potential twist, may also be a polymer yarn and be set by the said treatment; or it may be silk. The first two yarns may be polyamide or polyester monofil yarns A, B, previously set by heat treatment, twisted in opposite directions, treated by moist heat at a lower temperature than that of the original setting, and untwisted to such an extent, less than the original twisting as will render them dead; and they and a third unset, untwisted polymer yarn C may be knitted in successive courses, the resultant fabric being treated with, say, steam, boiling water, or hot dye. A pair of yarn ends A may, after twist-setting, be plied together, with a twist of opposite hand to that imparted to each end, to the dead condition, and the same treatment applied to a pair of ends B. An additional heavier splicing yarn, e.g. of silk, cotton, wool, or untreated nylon, having no potential liveliness, may be supplied from a fourth feeder for the reinforced parts of a stocking. Multifilament yarns may be used.

Patent GB-765945-A (GB)
Title: Improvements relating to the growing of primary ammonium phosphate crystals
IPC: C30B7/00
Filed: 1954-11-12
Abstract: A method of growing primary ammonium phosphate crystals comprises positioning primary ammonium phosphate crystal seeds in a container, pouring a growing solution of the phosphate into the container with the solution temperature 1.5 DEG C. or less above the saturation temperature of the solution, then gradually lowering the temperature of the medium surrounding the container to lower the solution temperature down to a temperature slightly in excess of the saturation temperature for the original solution to dissolve extraneous crystal nuclei and to partially dissolve the crystal seeds until the solution reaches a saturation equilibrium at this temperature due to the crystalline material thus dissolved in it, and thereafter causing the solution to crystallize on the seeds.  In a specific instance the room temperature surrounding the container is 3 DEG  to 4 DEG C. above the saturation temperature of the original solution, which is 46 DEG C., and the solution at a temperature not more than 1.5 DEG C, preferably 1 DEG C., above the saturation temperature is poured over a period of one hour, the container then being sealed with an air-tight cover.  The room temperature is then lowered over a period of 1.8 hours to 0.2 DEG  to 0.4 DEG C. above the saturation temperature of the original solution. At the end of this time the solution has become saturated and rocking of the container is commenced to cause the solution to flow across the crystal seeds, and the temperature is lowered gradually to cause the solution to crystallize on the seeds and form crystal bars. Specification 765,946 is referred to.

Title: Improvements in and relating to the storage of grain in large containers or silos
IPC: B65D88/74
Filed: 1937-02-19
Abstract: Grain stored in silos or other large containers is preserved by distributing through the grain cooling air maintained at 6-10 DEG C., the humidity of the air being so controlled that the moisture content of the grain is maintained below a maximum value which depends upon the temperature, the maximum allowable percentage of moisture in the grain being 19 per cent by weight for a temperature of 6 DEG  C. and falling to 15 per cent as the temperature rises to 10 DEG  C.  During the storage the humidity of the air used is such that the grain does not absorb or give off moisture, e.g. when storing grain of 15 per cent moisture content at 10 DEG  C. the humidity of the air is 70-75 per cent.  The silo is protected against external heat, e.g. in warm weather a part of the cooling air may be passed through its wall.  The moisture content of the grain, which is kept relatively low during storage, may after the storage be increased prior to grinding or other treatment. Specification 411,188 is referred to.

Title: Electrolytic erosion apparatus
IPC: B23H1/02
Filed: 1961-09-15
Abstract: <PICT:0948388/C3/1> A control for an electrolytic erosion machine tool senses variations in the gap between the cutting tool and the workpiece electrodes and causes the electrodes to be moved to alter the gap spacing in response to the variations thereby maintaining a predetermined gap spacing. As shown, variations in the gap spacing between a cutting tool 10 and a workpiece 12 cause corresponding variations in the back pressure of an electrolyte fed to the gap through a flow gauge 32 and a supply conduit 28. Signals from the gauge 32 and a back pressure gauge 36 are fed to an amplifier 38 the output of which varies as the gap spacing varies. The said output is applied to a servo-amplifier 24 having as another input a signal from a reference source 40 representing the desired gap spacing.  The resulting error signal output from servo-amplifier 24 controls a servo-motor, Fig. 1 (not shown) which moves the cutting tool to maintain the predetermined gap spacing. In a second embodiment, Fig. 3 (not shown) the control circuit comprises an inductor carried by one electrode and connected in one arm of a bridge energized by an alternating voltage, and a phase responsive circuit connected across the bridge which develops an error signal corresponding to variations in the gap spacing.  In a third embodiment, Fig. 7 (not shown) a transducer carried by one of the electrodes is arranged to send pulse signals from the source toward the other electrode and to receive the pulse signals reflected by the other electrode, and the control system senses variations in the time interval required to send and receive the pulse signal due to changes in gap spacing from a predetermined gap so as to develop corresponding error signals. If check spacing at a plurality of points between the workpiece 12 and the tool 10 is required, each embodiment may have several gap-variation detectors together with a sampling switch and an integrating circuit to obtain an average error signal in each case.
