Title: Improvements in or relating to crystal detectors for wireless reception
IPC: H01L29/00
Filed: 1925-01-22
Abstract: 244,604. Rooke, E. E. Jan. 22, 1925. Crystal detectors.-The holder of the crystal or the metal contact of a detector passes through an enlarged aperture in its support and is secured by frictional clamping means, so that the holder may be adjusted laterally to the limits of the aperture, and can be rotated in any selected position. The stem 2, Fig. 2, carrying the crystal cup passes through an enlarged hole in a strip support 6 by means of a loose washer 4 pressed aginst the support 6 by a spring 7 and a tapped washer 5 and knob 3 bearing against the outer side of the support. The, washer 5 is thicker at one side than at the other, so that as the knob 3 is turned, the whole crystal-holder pivots about an ecentric point. The holes through the loose washer and the support 6 are large enough to permit lateral movement of the stem 2. The ends of the strip 6 are oppositely slotted to enable them to engage rods d, e, Fig. 4, by which the end-caps b of the enclosing case are held in position. The metal contact 13, Fig. 6, is secured to a rod 11 slidable through a sleeve 14 which may be screwed or otherwise fixed into a hole in the opposite end-cap. The clamp 12 is connected to the sleeve 14 by a spring 15 enclosing the rod 11 and preventing it from rotating. The metal contact 13 is withdrawn from the crystal by turning the threaded knob 16, and is returned by the spring 15 when the knob is reversely rotated. A modified mounting for the metal contact, shown in Fig. 7, employs a hollow-rod 11 engaged by a threaded stem 18 secured to a knob 16a. The hollow portion of the rod 11 has a sliding key connection to a sleeve 19 which is fixedly secured to the end-cap of the glass cylinder. A small cap 22 screwed to the sleeve 19 is engaged on its outer side by the knob 16a and on its inner side by a washer 23 fixed to the stem 18. As a result the knob 16<a> and the stem 18 can rotate but cannot move axially. When the knob 16<a> is rotated, it advances or withdraws the rod 11 by the action of the screw, but the rod 11 is not rotated. The mountings of the orystal cup and the metal contact can be interchanged.

Title: Improvements in high vacuum distillation process
IPC: B01D3/12
Filed: 1937-01-29
Abstract: <PICT:0487697/III/1> In the high-vacuum short-path distillation of oils containing an active principle such as a vitamin, sterol or hormone, the latter is accumulated in the distillate by flushing the condensing surface with a liquid which is continually recirculated thereto before recovering the active principle from the resulting mixture.  Apparatus of the usual type is provided with a container 14 for collecting the mixed liquids from the condensing surface 6, a circulating pipe 22 provided with a magnetic pump 23 and a distributing header 24 arranged above an annular plate 25 for spreading the re-cycled liquid over the condensing surface. The container 14 is preferably cooled to separate solids which are retained above a filter 15.  In a modification of the invention, the evaporating surface 7 and the condensing surface 6 are interchanged, the recirculating pipe 22 then supplying the mixed liquid from the condensing surface back to the same centrally disposed condensing surface.  A number of such units may be connected in parallel and each may contain additional distributing headers 24 to enable the distribution of flushing liquid at more than one place.  The pump 23 comprises a magnetically operated apertured plunger closed by a ball valve, movement of the plunger by a solenoid displacing the liquid before it.  The invention may be applied to fish and vegetable oils for recovering particularly vitamins, sterols and hormones.  Suitable flushing liquids, depending on the vapour pressure conditions, comprise ethyl hexyl phthalate, castor oil, acetone, glycerine, kerosene, cotton-seed oil, triacetin, decalin, acetylene-tetrachloride, glycerine ethyl lactate and the substance known under the Registered Trade Mark "Nujol."  Temperatures, pressures and distances apart of the distilling and condensing surfaces are specified.  In an example, cod-liver oil is distilled in the apparatus at a temperature of 90-220 DEG  C., a pressure of 1 micron and a mean free path of 1 inch with ethyl hexyl phthalate as the flushing liquid.  The mixed distillate is chilled, cholesterol separating out, and the liquid recycled over the condensing surface to accumulate vitamins A and D, which are finally recovered.  U.S.A.
