Title: Ice-making machine
IPC: F25C1/16
Filed: 1927-09-26
Abstract: 293,602. Fairweather, W. C., (Sperling & Co. Kommanditges.). Sept. 26, 1927. Valves, arrangement of.-In a pump 1 of a small vacuum ice-making machine, the suction valves 14, Fig. 2, in the piston 3 and the exhaust valves 10 on the cylinder cover 8 have projecting spindles as shown so that they are positively opened by the piston movement just before it reaches the ends of its stroke. A disc 13 carried by the stufting-box 12 serves as a common abutment for the exhaust valve springs. Oil to seal the stufring-box and valves is placed above the cylinder cover 8, and an oil chamber comprising two parts 16, 17 clamped together by a bolt 27 is placed between the suction pipe 20 and the cylinder. A pipe 25 extends from above the oil level in the chamber to the bottom of the cylinder, and another passage 26 leads from below the cylinder. A pipe 25 extends from above the oil provided in a partition 19 separating the chambers 16, 17 and out of alignment with the pipe 25. By this means the oil at the bottom of the cylinder acts as a sealing and non-return device, while surging of oil into the suction passage is avoided.

Title: Improvements in neutron flux detectors
IPC: G21C17/108
Filed: 1964-06-19
Abstract: 1,023,117. Detecting neutrons. ATOMIC ENERGY OF CANADA. June 19, 1964 [July 29, 1963], No. 25504/64. Heading G6P. A neutron flux measuring device is formed of an electron emitter electrode and a collector electrode separated by a solid insulator. The emitter generates an electron current when subjected to a neutron flux and a potential difference is developed across a load resistor, connected between the two electrodes, proportional to the emitter current. A coaxial cable connects the electrodes to an indicating instrument and in order to reduce the effect of " background " signals, due to the incidence of radiations upon the cable, a second similar cable is mounted adjacent to the first. The " background " signals generated in the two cables are applied in opposition to the indicator. The emitter material may be aluminium, vanadium, silver, cadmium or gadolinium.

A plate 40 positioned beneath the opening(s) 34, a slot 44 in the plate 40 dimensioned to permit the passage of the forks 46 beyond the plate, a receptacle for receiving the forks, the slot 44 also permitting the passage of the spoon handles but being dimensioned to prevent passage of the bowl portions of the spoons so that the latter are suspended by the plate 40, means for moving, e.g. by means of connections 16 to vibrator 18, suspended spoons 50, 54 along the length of the slot 44, and a receptacle at the end of the slot for receiving the spoons. The sliverware is delivered via conduits 14 on to the bed 10 which is supported on a pan 12 mounted on vertical plates 16 connected to the vibrator 18. The bed 10 is formed with troughs 20 which move the silverware towards the openings 34. The knives are directed from the chute 25 through an opening 26 in the end wall 28 of the pan 12. Cam surfaces 36 midway along the troughs 20 locate the handles of the forks and spoons on edge to facilitate their discharge through the openings 34. Chutes 38 located beneath the openings 34 deliver the forks and spoons onto the plate 40 which is constituted by the bottom of the pan 12. A number of slots 44 are formed in the plate 40 and are sufficiently wide to permit forks 46 to fall through the plate 40 into suitable receptacles whilst being directed by guides 48. The slots 44 communicate at their ends with openings 52, Fig. 10, through which the spoons drop into a receptacle. A cam 56 positioned beneath each slot 44, Figs. 13d, 14, directs the handles of long-handled spoons 54 for movement along one side of a wall 58 while the short-handled spoons 50 move along the other side of the wall. Air streams discharged from openings 62 in nozzles 60 push the short-handled spoons 50 to said other side of the wall 58. A flexible brush or arm may be used instead of the air streams. Alternatively, other cams may be used for diverting the short-handled spoons. Suitable brushes or fluid streams may be employed for moving the silverware on the bed 10 and plate 40 either in lieu of, or in conjunction with, the vibrator 18.

Title: Improvements in resolving chlorosilane mixtures
IPC: C07F7/20
Filed: 1953-09-23
Abstract: Organochlorosilanes are separated from a liquid mixture containing organochlorosilanes and chlorosilanes by adding to the mixture an aliphatic tertiary amine or a cyclic tertiary nitrogen compound and separating the solid addition compounds formed between the chlorosilanes and said amine or nitrogen compound from the organochlorosilanes, e.g. by distillation.  Suitable tertiary amines and cyclic nitrogen compounds are trimethylamine, triethylamine, pyridine, 3- and 4-methylpyridine, 4-(51-nonyl)-pyridine, a dipyridyl, phenazine and quinoline. In an example, trimethylchlorosilane is separated from silicon tetrachloride with pyridine.  Methyltrichlorosilane may be separated from silicon tetrachloride by a similar procedure.  The solid addition products formed from silicon tetrachloride, silicochloroform, dichlorosilane and hexachlorodisilane with pyridine and 3- and 4-methylpyridine, and from silicochloroform and dichlorosilane with trimethyl- and triethyl-amine are also referred to.  The addition compound may be broken down with anhydrous hydrogen chloride to regenerate the amine or cyclic nitrogen compound.ALSO:Chlorosilones are separated from a liquid mixture of chlorosilones and organochlorosilanes by adding to the mixture an aliphatic tertiary amine or a cyclic tertiary nitrogen compound to precipitate solid complexes of the chlorosilones with the said amine or nitrogen compound.  Suitable amines and nitrogen compounds are trimethylamine, triethylamine, pyridine, 3- and 4-methyl-pyridine 4-(51-nonyl)-pyridine, a dipyridyl phenazine and quinoline.  In an example a complex of pyridine and silicon tetrachloride is precipitated from a mixture of silicon tetrachloride and trimethylchlorosilane.  A mixture of silicon tetrachloride and methyltrichlorosilane may be similarly treated. The complex compounds formed from silicon tetrachloride, silicochloroform, dichlorosilane and hexa-chlorodisilane with pyridine and 3- and 4-methylpyridine, and from silicochloroform and dichlorosilane with trimethyl- and triethylamine are also referred to.  The complexes can be broken down with anhydrous hydrogen chloride to regenerate the chlorosilanes.
