Title: Improvements in or relating to a process and apparatus for the dry separation of masses of materials
IPC: B03B4/02
Filed: 1927-11-10
Abstract: 307,526. Sutton, H. M., Steele, W. L., and Steele, E. G. Nov. 10, 1927. Pneumatic separating. - Relates to apparatus for separating granular material, such as a mixture of coal and heavy impurities, of the kind in which the materials are given a jigging movement on a pervious reciprocating deck which comprises receiving and delivery portions set at an angle to each other and through which upward currents of air are passed. The invention is described as applied to apparatus having the Y- shaped separating deck shown in Fig. 1, and described in Specification 207,094 and comprises (a) inclining the delivery ends B upwardly relatively to the receiving portion A of the deck as shown at 13, Fig. 13; (b) forming the riffles C of L-sectioned perforated strips, the horizontal arms 1 of which are lifted slightly from the surface of the deck as shown in Fig. 10 so as to avoid obstruction of the, deck perforations by particles carried in the air stream; and (c) providing means at the central deck rib 32 for directing a current of air across the path of flow of the materials over the deck. The perforated riffles taper down towards the central unobstructed passage 4 on the deck and are combined with the usual solid riffles to form troughs in which the effect of the air pressure is reduced so as to facilitate the settling of the small particles of heavy material which is conveyed by the troughs to the passage 4. In order further to control the air pressure in the areas occupied by the riffles, perforated metal troughs 6, Fig. 12, with closed rear ends are secured to the under surface of the deck. The means for providing a cross-current of air at the banking bar 32 consists of a box 33, Fig. 15, connected by an expansible pipe 40 with the air chamber under the deck and provided with a horizontal slot 34. The box is mounted by the adjustable fastening 37 to permit control of the direction of the air current. The air controlling baffle-plate 22, Fig. 2, in the air chamber 15 is hinged at its front end 24 and adjustably secured at its rear end 26. The passage of the air through the plate is directed rearwardly by inclined lips 21. Preferably the edges of the plate under the tailings discharge areas of the deck are unperforated and the perforations in the plate increase in size rearwardly and laterally. A second fixed baffle-plate 22<1> with rearwardly inclined lips 21<1> may be provided. The surface of the deck is roughened for the feed of the materials by stamping the necessary configuration in perforated sheet metal. In Fig. 12, the deck is shown as formed of corrugated sheet material 8. A modification consists in stamping projections and recesses in the material.

Title: Improvements in apparatus for cooling internal combustion engines
IPC: F01P11/02
Filed: 1963-07-30
Abstract: 1,032,460. Cooling internal-combustion engines. J. L. GRATZMULLER. July 30, 1963 [Aug. 1, 1962; Aug. 27, 1962], No. 30216/63, Heading F4U. Apparatus for water cooling an internalcombustion engine 2 comprises the water jacket of the engine connected by a pipe 4 to a coil 6 of a boiler 8 of an evaporative heat exchanger, a centrifugal pump 10 and a return pipe 12 to the water jacket. Water is maintained under pressure by an auxiliary tank 14, connected to pipe 4, having a tube 20 controlled by a valve 22 which is connected to a source of pressurized gas. Water can be added to tank 14 which has a visible water level gauge 18 by a feed bottle 16. The coolant water in coil 6 vaporizes water in the boiler and is thereby cooled. The resulting water/vapour mixture from the boiler rises in duet 24 to a condenser 28, cooled by fan 30, where additional water condenses before the mixture passes into a separating chamber 26 from which vapour escapes to atmosphere through vent 40 and condensed water returns through pipe 36 to a reservoir 32 having a visible external water level gauge 34. The coolant may flow in the direction indicated or in the reverse direction. In other embodiments a radiator in the circuit downstream of the engine provides sufficient cooling capacity for normal operations and the evaporative heat exchanger is used only when additional cooling is required, in these embodiments the condenser and fan are omitted. The coil 6 can be placed in an auxiliary circuit and connected to the main circuit, by a 3-way valve controlled by a thermostatic switch, only when the outlet water temperature from the engine becomes excessive. Alternately, the coil 6 can be in the main circuit and the pressure in the boiler raised by a spring-loaded valve in the vent 40 to prevent vaporization below a certain temperature. The valve may be operated by a solenoid controlled by the said thermostatic switch or be preset to open at a given pressure.

Title: Process for the manufacture of alcohols from germinal gland hormones
IPC: C07J9/00
Filed: 1934-10-22
Abstract: Secondary or tertiary alcohols are prepared from germinal gland hormones of the C18 and C19 series which contain a keto group by reaction with organo - metallic compounds, followed by decomposition of the reaction product in the usual manner.  The secondary alcohols are produced by the use of Grignard reagents such as isopropyl magnesium iodide which tend to the formation of unsaturated hydrocarbons.  Suitable starting materials are the follicle hormone C18H22O2 and the testicle hormone C19H30O2 and derivatives of these hormones in which the hydroxyl group is replaced by a group which can be re-converted to a hydroxyl group on hydrolysis.  Other compounds which may be used as starting materials are saturated or unsaturated cyclopentano-polyhydro-phenanthrenes of the C18 or C19 series which exhibit male or female hormone characteristics.  Instead of Grignard reagents there may be used organic zinc halides or organic alkali compounds or mercury alkyl compounds.  In examples: (1) Follicle hormone is reacted with methyl magnesium iodide and the product decomposed with water and acid; (2) Follicle hormone benzoate is reacted with isopropyl magnesium iodide, and the product decomposed with water and acid. The resulting ester on decomposition with potassium hydroxide yielded dihydrofollicle hormone.  Physiological tests are described to show the increased activity of the reaction products as compared with the starting materials.  Samples have been furnished under Sect. 2 (5) as follows: (1) and (2) methyl (or ethyl) magnesium iodide and follicle hormone benzoate are reacted to yield the 17-methyl (or ethyl) dihydrofollicle hormone benzoate followed by hydrolysis to produce the hormone; (3) methyl magnesium iodide and male gland hormone C19H32O2 are reacted and the ester first formed is hydrolyzed to yield 17-methylandrostandiol-3 : 17; (4) and (5) magnesium methyl (or ethyl) iodide and trans-dehydroandrosterone are reacted and the ester produced hydrolyzed to yield D <5,6>-17-methyl (or ethyl) trans-androsten-3 : 17-diol; (6) methyl magnesium iodide and trans-androsterone are reacted and the 17-methyl-trans-androstan-3 : 17 diol isolated by means of its semicarbazide and crystallized from ethyl acetate-hexane mixture; (7) ethyl magnesium iodide and transandrosterone are reacted, the products worked up as in sample 4 to give 17-ethyl-transandrostan-3 : 17-diol; (8) ethyl magnesium iodide and androsterone are reacted and the resulting 17 - ethyl - cis - androstan - 3 : 17 diol crystallized from ethyl acetate-hexane mixture; (9) isopropyl magnesium iodide and androsterone acetate are reacted, and the androstandiol formed isolated by means of its semicarbazide; (10) isopropyl magnesium iodide and transandrosterone acetate are reacted and worked up as in sample (9) to give trans-androstandiol-3 : 17; (11) isopropyl magnesium iodide and dehydroandrosterone acetate are reacted and worked up as in sample (9) to give transandrostendiol 3 : 17.
Patent GB-1066634-A (GB)
Title: Signal translating circuits using field-effect transistors
IPC: G11C16/04
Filed: 1963-12-20
Abstract: 1,066,634. Circuits using field-effect transistors. RADIO CORPORATION OF AMERICA. Dec. 20, 1963 [Jan. 2, 1963], No. 50468/63. Headings H3A and H3T. In a signal-translating circuit comprising an insulated-gate field-effect transistor with a substrate connection, a signal is derived at the substrate from the input signal or signals applied to the transistor and serves either as the output of the circuit or itself effects a further control within the circuit. In a first embodiment. Fig. 6, the input applied to the insulated gate electrode is coupled capacitively to the substrate and thereafter is rectified at the junction between the substrate and source electrode and, in the case where the voltage V 2  applied to the drain electrode is of zero value, also at the junction between substrate and drain. The output appearing at the substrate terminal may be employed either as detected modulation for subsequent amplification or for automatic gain control. The circuit may serve as an I.F. amplifier in which ease the resistor 122 is replaced by a tuned circuit. The output amplitude varies with D.C. bias applied to the gate electrode, Fig. 9 (not shown), and also with frequency, Fig. 8 (not shown), so that the current may serve as a frequency discriminator. Fig. 10 shows a " constant-angle " limiter or clipping circuit producing an output whose mark-space ratio is substantially independent of input amplitude. The input waveform to be clipped is applied from source 144 in series with the sourcedrain path of the transistor. The gate electrode is biased by battery 149 so that the device does not conduct when a positive voltage is applied to the drain electrode. However, in alternate half-cycles of the waveform from source 144 a negative voltage is applied to the device which then functions as a reversely connected fieldeffect transistor so that a square-wave output is produced across load 146. At the same time, however, rectification takes place at the junction 140 so producing a negative voltage at the  substrate which is coupled through battery 149 and resistor 148 to the gate electrode. The bias on the gate electrode thus varies in accordance with the amplitude of the signal applied from source 144 in such a fashion as to maintain the conduction phase angle of the transistor substantially constant. Fig. 11 shows a phase detector circuit, e.g. for use as the chroma demodulator circuit in a receiver for the N.T.S.C. colour television system, in which the output depends solely on the phase angle between two oscillations of the same frequency, e.g. the output of chroma band-pass amplifier 74 and colour subcarrier local osillator 78. The signals from circuits 74 and 78 are applied to the gate and source electrodes respectively and an output dependent upon the phase difference between these signals is developed across the output resistor 88. A voltage dependent upon input signal amplitude is applied from the substrate as bias to the grid electrode to render the output substantially independent of input signal amplitude.
