Title: Process for the industrial utilisation of fish and fish waste
IPC: A23J3/30
Filed: 1923-09-14
Abstract: Fish and fish waste are hydrolyzed by standing with occasional stirring in excess of water at 30-60 DEG  C. until the flesh is dissolved.  After the oil has been removed from the surface, the liquor is run off from the bones, distilled with slaked lime to obtain ammonia and amines, and then filtered.  The filter residue is dried and distilled whereby lime, ammonium salts, esters, tar and oils are obtained.  The filtrate is evaporated and distilled dry, producing ammonium salts, esters, tar, oils, animal charcoal and from herrings, cooking salt.  The ammonia and amines may be worked up to obtain cyanogen compounds, ammonium salts, or nitric acid.ALSO:Fish and fish waste are hydrolyzed by standing with occasional stirring in 2.5-3.0 parts or other excess of water at 30-60 DEG  C. until the flesh is dissolved.

Abstract: 1,038,423. Supply systems for high pressure gas-discharge lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 4, 1964 [June 7, 1963], No. 23185/64. Heading H2H. A circuit for igniting a high pressure discharge lamp 30 having main electrodes 31, 32 and an auxiliary electrode 33 adjacent the main electrode 31 has the auxiliary electrode 33 connected to the remote main electrode 32 by way of the two windings of an autotransformer 4 and to the adjacent main electrode 31 by way of one winding only of this transformer. On connection of the circuit to an A.C. supply 1, 2 current flows in the ballast inductor 6 and the winding 42-41 of the transformer 4. The voltage induced in the winding 42-43 of the transformer is applied to the electrodes 33, 31 producing ionization of the gas filling in the lamp 30. The voltage between the electrodes 33, 32 is equal to the sum of the voltages in the transformer windings 42-41, 42-43 thus producing a glow discharge between the electrodes 33, 32 which causes ignition of the lamp 30. A resistor 5 limits the current through the auxiliary electrode 33.

Abstract: 700,831. Automatic tension control systems. ENGLISH ELECTRIC CO., Ltd. Sept. 26, 1952 [Oct. 5, 1951], No. 23234/51. Class 38 (4) In a system for automatically controlling in dependence on a strip tension, a D.C. motor driving a coiled drum for a strip rolling mill, an additional control is provided in dependence on roll force variations to assist the tension control. Additional features :-(i) Current limiting, (ii) The removal of tension control during "wrapping." The primary tension control system may be that of Specification 643,537 (employing a jockey-roller bearing in the strip) but as shown comprises a constant current system. The motor field exciter 16 is controlled in accordance with the difference between the voltage drop across a resistance 14 in the motor armature circuit and a reference voltage from a generator 19. The additional control is provided by a resistance straingauge 23 subjected to the roll load, and having its output amplified at 22 to additionally energize the fields 19a of the reference generator with an increase in load so that the tension of the strip is increased. Additional features.-(i) A field 19b is cannected through a blocking rectifier 25 so that it is only energized when the voltage across resistor 14 exceeds a reference voltage from potentiometer 24, (ii) relay 26 is connected through blocking rectifier so that it is de-energized when the voltage across resistor 14 is less than that across potential divider 24 (during "wrapping") and disconnects the tension control at contacts 26a, 26b.

In or for use in an electric motor or generator, a brush arm 12 is clamped and located in a recess 11 of, e.g., a brushrocker ring 10, by a screw 17 which applies pressure to a device which has two legs 14, 15 the latter leg having an inclined face which bears against an inclined face 16 of the brush arm 12. Thereby clamping pressure is exerted against both the base of the recess, and a side wall 13 thereof, and the arrangement ensures constancy of location of the arm against the wall 13 when shims 19 are removed to compensate for wear or truing-up of the commutator (hot shown). Such shims may then be housed in a recess 19a in the top of the device 14, 15. In a modification, Figs. 5 ... 8, not shown, the leg 14 is housed in a separate recess in the ring 10. The Provisional Specification describes the arrangement as of general application.

Title: Machine for winding interleaved capacitors
IPC: H01G13/02
Filed: 1948-09-08
Abstract: 640,822. Condensers. BRITISH THOMSON-HOUSTON CO., Ltd., CLARKE, G. H., and HARRIS, W. S. Sept. 8, 1948, No. 23651. [Class 37] A machine for winding spiral condensers comprises spindles 2 respectively for metal foil 4, e.g. aluminium or tinned copper, and an insulating material 5, e.g. paper, the foil and paper strips being wound on a mandrel 6 after following a path determined by guide rollers 7. An indicator 15 on the path marks the point at which terminal leads 16 are to be inserted between the strips prior to each winding operation. Upon starting a motor 25 rollers 14 which grip the strips separate through the action of a cam 13 and the mandrel 6 rotates to wind the strips. A spindle 19, which carries the cam 13 and a second cam 11, is driven through gearing 12 from the mandrel 6. As the winding operation nears completion a gap in cam 11 coincides with a spring-loaded push rod 10 acting through links 9 on a member 8 which is caused to perforate the foils 4, the paper 5 however being defended by plates 26 on the member 8. Just prior to perforation of the foil 4 rubber pads 17 on member 8 grip and retard the foil, thereby tearing it at the previous perforations. The paper 5 however continues to pass between rollers 14 and so the foil 4 is effectively cut back at each end of the capacitor roll to minimize the risk of a shortcircuit. The paper strips 5 are then cut by a knife 23.

Abstract: <PICT:0811699/IV (b)/1> Fatty acid sulphoethylesters are made by mixing together sodiumisethionate with a fatty acid halide under liquid conditions, and delivering the mixture to a heated surface swept by rapidly moving members which simultaneously produce a thin film of said mixture and violent turbulence in said mixture, at an accurately controlled temperature for a period of time until the reaction is substantially complete.  This may be done by carrying the reaction mixture over a surface by the combined effect of gravity and the motion of said members at such a speed as to permit complete reaction during the passage through a heated cylinder.  Suitable apparatus comprises a reactor 1 having a steam jacket 2 for control of temperature and a rotor member 8 with blades 11.  An inlet 14 for the reaction mixture is provided and material is discharged from the outlet 4 in solid form.

Abstract: 839,636. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 7, 1956 [Aug. 10, 1955], No. 24209/56. Class 37. A method of making a PN junction device comprises heating an activator metal characteristic of one conductivity type in contact with a semi-conductor body of the opposite conductivity to form a PN junction with an overlying metal layer, coating a heat sink with solder, placing the metal layer and solder in contact, with an insulating spacer at least partially surrounding the layer, and heating the heat sink to fuse it to the entire surface of the layer. In the embodiment a mass of indium or zinc is alloyed to one face of an N- type Ge body 1 to form a P-type zone beneath the surface overlain by a projecting region of alloy material 6 which serves as emitter in the finished transistor. An apertured plate 2 of copper or nickel is ohmically connected to the opposite face of the body and a collector electrode 4 of tungsten or phosphor bronze wire forms an electroformed point contact with the body in the aperture. The projecting alloy material is connected to a copper heat sink 8 by providing the latter with a layer of solder 9, bringing it into contact with the alloy as shown and then heating the sink sufficiently to melt the solder and the alloy surface to form a rigid bond. The process is facilitated by the use of the insulating spacer 11 which at least partly surrounds the alloy as shown.
