Title: Abrasive grain
IPC: B24D18/00
Filed: 1960-09-23
Abstract: An abrasive granular alumina is made by compacting particles of bauxite into agglomerations, and then sintering at a temperature below the fusion temperature of the bauxite, to induce limited recrystallization of said particles (i.e. crystal growth to about twice the size of the particles in the original powder.) The grains produced have a generally smooth surface, and the crystals within each grain are randomly orientated, a major proportion of said crystals being in the size range 5-30 microns. The grains may have a hard surface, and up to one half of the crystals within each grain may be lath-shaped, the remainder being equidimensional. The grains may be composed of a -Al2O3, 3Al2O3,2SiO2, and all of the SiO2 in such grains may be in intersticial relation to the crystals therein. The particles of bauxite used usually have sizes less than 12 microns, and are produced, for example, by ball-milling natural bauxite. The particle size of the agglomerated material is 4-5 microns, and the grain size of the agglomerate falls within the range 6-16 mesh, a pressure of 5 tons/sq. inch being suitable for producing the agglomerate from the bauxite particles. The sintering temperature is usually in the range 1375-1570 DEG C., and the time period of sintering is from 15 minutes to 4 hours or more, the longer time being needed at the lower temperature, and the time also depending on the type of kiln used. The use of the abrasive grain material by incorporating it into a grinding wheel is described. Specification 755,116 is referred to.ALSO:An abrasive for a grinding wheel consists of a particular abrasive grain dispersed and supported in a resin. The grains are sintered grains of bauxite, each grain being made up of a plurality of primary bauxite particles which have been recrystallized in situ, said grains having a generally smooth surface and having random crystal orientation therein, a majority of the crystals being from 5 to 30m in size. The grains have a hard, shell-like surface, and up to half of the crystals of each grain may be lath-shaped, the remainder being equidimensional. The grains may be composed of a -Al2O3, 3Al2O3.2SiO2, wherein all of the amorphous SiO2 is preferably in interstitial relation to the crystals. Specification 755,116 is referred to.

Title: Process for freezing food using liquid refrigerant
IPC: F25D25/04
Filed: 1967-05-31
Abstract: Foodstuffs are frozen in a bath of a liquid, halogenated alkane refrigerant having a boiling point of from - 5 to - 50 C. and a density such that the foodstuffs float therein. The foodstuffs are allowed to fall freely into a part of the bath which is maintained in a turbulent state. As shown, foodstuffs 10 pass through a hopper 11, a vibrated chute 13, a vibrated hopper 14, valve 18, a vibrated chamber 20, valve 19 and vibrated chute 21 into a freezing chamber 29 which contains the refrigerant bath and a screw conveyer 32. Scoops 36 supply the foodstuffs to a discharge pipe 38 from which they pass through a valve 40, a vibrated chamber 42, valve 41, and chamber 47 (in which they are sprayed with dry air) to a collecting bin 43. Valves 18, 19 and 40, 41 are operated in a predetermined sequence such that loss of refrigerant vapour is minimized. A vacuum pump 45 removes refrigerant vapour from the foodstuffs in chamber 42 and this vapour, together with that from the outlet 52 of the freezing chamber passes to a compressor 53. The compressed vapour is condensed at 60 and passes to a separator 61 from which the liquid is supplied through a valve 63 into the liquid bath which it enters in the form of a spray 31 maintaining the inlet end of the bath in a turbulent state. Part of the vapour from separator 61 is returned to the compressor section under the control of valve 69 and the remainder passes through a condenser coil 64, cooled by refrigerant from the bath, to a further separator from which uncondensed gases are vented to atmosphere and liquid is supplied, via valve 67, to the bath. Should valve 63 be blocked by frozen moisture the liquid level in separator 61 rises and a device 73, responsive to this level, causes the valve to repeatedly open and close until the ice is dislodged. Liquid from the bath may be circulated by pump 34 to spray nozzles 35 in the freezing chamber. An electrically heated vapourizer 76 is provided for separating food oils from the liquid refrigerant and returning refrigerant vapour to the compressor. The pitch of the conveyer may decrease in the downstream direction, (Fig. 2, not shown) or the conveyer may have a downstream section rotating more slowly than an upstream section. Quantitative examples are described and preferred refrigerants, dimensions and operating conditions are specified together with a list of foodstuffs which may be frozen in the above apparatus.

Title: Terry loom with fell shifting means
IPC: D03D27/08
Filed: 1967-09-15
Abstract: In a terry loom additional forward and rearward rotations are imparted to the take up roll 51 which in conjunction with similarly timed movements of a ground warp shifting roll 14 move the fell to produce three pick terry cloth. Normal take up is from a rocker shaft 64, through a pawl and ratchet drive 81 to a sun wheel 102 and planet wheels 103 to drive the shaft 51a. The second driving connection to produce the additional rotation in the take up roll 51 is from a terry cam 122, terry rocker shaft 116, link 114, bell crank 112 and link 110 to a second sun wheel 101. The ground warp shifting roll 14 is carried arms 130, 130a on each side of the loom (only one is shown) and is driven by a crank 115 through a link 131 from the terry rocker shaft 116 and moves in cooperation with the take up roll to move the fell. When the terry cams low surface engages its follower the link 110 moves upwardly and produces an increased take up on take up roll 51 and this occurs with a downward movement of the shifting roll 14 to allow the fell to move forwards. Thereafter, following a number of loose picks a high part of terry cam 122 produces a corresponding rearward movement, normal take up being separately operated at each pick. A pattern control swinging latch arm 140 can be operated to maintain the terry cam follower 121 out of contact with the terry cam 122 during non terry weaving operation of the loom and a pawl drive to the terry let off motion is disengaged so that the terry warps are maintained under normal tension corresponding to the tension of the ground warps during this period.
