Patent GB-827773-A (GB)
Title: Moisture determining apparatus
Inventor: CONTI JOHN D
IPC: G01N19/10
Filed: 1957-04-15
Abstract: 827,773. Determining moisture content of materials. AMERICAN VISCOSE CORPORATION. April 15, 1957, No. 12203/57. Class 106 (2). [Also in Group XX] Test apparatus for determining the moisture content of material 39 comprises means 69 for applying a stretching load to the material, a scale 135 for indicating the moisture content of the material as based on its degree of elongation and a device 109 for maintaining the stretching load for a predetermined time period. As shown, the test sample 39 is held by clamps 43, 45, a weight 147 being attached to the lower end to ensure that the sample is taut. The lower clamp 45 is fixed and the upper clamp 43 connected to a pivoted beam 21 which is held horizontally by a brake (not shown) acting on an arcuate segment 89, and by a latch 75. Weights 69 are adjustably mounted on the beam 21 and provide the stretching load for a test. To test the material, latch 75 is released, operating a micro-switch 83, which energizes a solenoid 109 through an electric timer. Energization of the solenoid 109 pivots the segment 89 against the action of a spring 93 thus releasing the brake. Thus the load 69 acts on the sample 39 until at the end of the predetermined period, the solenoid 109 is de-energized and the brake reapplied. The extension of the test piece is then read from the scale 135 on the segment 89, and this is a measure of the moisture content of the sample. The scale 135 may be graduated directly in terms of moisture content. Serrations 125 on a second arcuate segment 127 are engaged by a pawl 115 to prevent the beam 21 from oscillating when released.

Patent GB-707978-A (GB)
Title: Improvements in or relating to methods of growing crystals
IPC: C30B7/00
Filed: 1950-05-22
Abstract: <PICT:0707978/III/1> Crystals, e.g. of ethylene diamine tartrate or lithium sulphate, are grown from seed immersed in a supersaturated solution of the salt by cooling (or heating in the case of substances such as lithium sulphate, which have a negative solubility/temperature coefficient,) the solution from one predetermined temperature to another, and then bringing the temperature back to its initial value while maintaining the solution supersaturated by passing it during this stage at an appropriate temperature through recharging apparatus containing solid solute. The cooling (or heating) and recharging steps are repeated until the crystals are the desired size.  Limitation in size of crystals grown by the falling temperature method due to instability of certain solutions outside certain temperature ranges is thereby avoided.  The Figure shows suitable recharging apparatus comprising a wide bore tube 2 containing solution 1 and solute 12 closed by end caps 3, the upper having a liquid inlet 4, a funnel 13 for introducing solid solute and the lower having a liquid outlet 4.  A filter 10 is interposed between outlet and solute.  The liquid inlets and outlets have enlargements 5 in which are thermometers 8.  The temperature of the solution is controlled by heater 9 surrounding the tube 2 and auxiliary heaters 19, 20 surrounding tubes 17, 18 connected to the liquid inlet and outlet.  A pump 21 draws solution from the tube 2 and feeds it to the growing tank through a tube 23 of heat insulating material having outlet holes 25, solution being withdrawn from the growing tank by the U tube 22. The flow of solution may however be in the reverse direction, the filter 10 then being at the top of tube 2. The time the recharging apparatus is connected to a growing tank may be much less than the time crystals are growing by the fall (or rise) in temperature and one apparatus may therefore serve a number of growing tanks.  When the recharging apparatus is connected to a growing tank the saturation temperature of the solution in the tank is continuously measured by the apparatus described in Specification 684,042, [Group XX], and the temperature in the tank maintained about 2 DEG C. below (or above) the saturation temperature to keep the solution supersaturated.  When not in use the tubes 22 and 24 may dip in another container for solution and the circulation of solution through the saturator maintained continuously.  Specification 707,976 also is referred to.

Abstract: 491,986. Jaw crushers. NORDBERG MANUFACTURING CO. May 5, 1937, No. 12825. Convention date, May 9, 1936. [Class 59] In a jaw crusher in which the moving jaw is pivoted at the top and is actuated by an eccentrically operated slide block in vertical alignment with the pivot, the side plate members of the movable jaw move with the jaw and close the sides of the crushing cavity, removable liner plates being attached to the side plates. As shown the moving jaw is pivoted at its upper end on an axle 12 and is oscillated at its lower end by an eccentric 52 operating a sheave 54 slidable in guides 53 in a recess in the jaw. The sides of the jaw are flanged and carry renewable side plates 67, 68 and shaped plates 74, 75, the lower ends 78, 79 of the latter acting as wedges to retain the crushing plates 61, 60 in position. Further side plates 71, 72 are wedged in the flanges alongside the jaw plates 61, 60. The fixed jaws 107 are each pivoted on an axle 96 and are retained in position by a bolt 144 and spring 147. The fixed jaws each bear against a block 143 which moves rearwardly, when an uncrushable object enters the jaws, against the pressure of springs 122, Fig. 4. The block 143 enters a recess in a bridge piece 120 and its distance from the fixed jaw is adjusted by horseshoe shaped shims 150. A movable guard plate 115 bears on top of the fixed jaw. As applied to a crusher with a single crushing space a lip extends from the curved part 76 of the plate 74 to form a lead-in lip. The machine is lubricated from a pump 200, Fig. 2, the oil passing to a pipe 212 and thence by a central bore in the cam-shaft to each of the bearings. An extension 227 of the pipe 228 leads oil to a central bore in the axle 12 and thence to the bearings, the overflow returning through a pipe 34 to a sump 36. Oil sealing plates 219 protect the eccentric bearing and other plates 225, 226 seal the main bearings. The ends of the axle 12 are sealed by rings 26.
