Title: Improvements in or relating to the treatment of vitamins
IPC: A61K31/355
Filed: 1961-12-29
Abstract: An autogenous free-flowing high density, solid, high potency Vitamin E active beadlet product consisting essentially of d-a -tocopheryl acid succinate is obtained by melting the compound, establishing and maintaining the molten compound as dispersed droplets, solidifying and hardening the droplets by cooling below the melting-point of the compound to form beadlets and separating them.  In examples, d-a -tocopheryl acid succinate was melted at 80-85 DEG  C. and then dispersed in an aqueous solution of methyl cellulose, locust bean gum or gelatin which had been digested with pepsin.  The resulting dispersion was rapidly cooled to 7-23 DEG  C. and held at that temperature until the droplets had solidified and hardened.  The product had a bulk density of 24-38 pounds per cubic foot and a particle size in the range from 20-100 mesh U.S. screen size.

Title: Process for obtaining products rich in bifidus ii factor
IPC: C07K14/435
Filed: 1963-11-28
Abstract: Products rich in bifidus II factor are produced by subjecting fish intestines, either alone or accompanied by other fish viscera, to autolysis by the action of their own proteolytic enzymes, and then heating the autolysate to deactivate said enzymes.  When the fish intestines make up 5% or less of the total fish viscera, autolysis is carried out in the presence of an added proteolytic enzyme e.g. papain or ficin.  Before autolysis, the total fish viscera may be subjected to a bactericidal treatment by the injection of steam at a temperature of at least 100 DEG C.  The fish viscera may be mixed with animal liver, e.g. ox liver, before autolysis.  After heating, the autolysate is separated and evaporated under reduced pressure to give a mass rich in bifidus II factor.  The bifidus II factor so produced may be mixed with a carrier to form a pharmaceutical composition suitable for oral administration.  The composition may also contain Lactobacillus bifidus and/ or Escherichia coli, and may be in the form of ampoules, capsules or tablets.

Abstract: 1,142,513. Thyrister control circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 23 Oct., 1967 [26 Oct., 1966], No. 47969/66. Heading H3T. [Also in Division H2F] In a thyristor control circuit, energy stored in a device 5 is applied to trigger a thyristor 1 or la, when a control element 6 or 6a is triggered. In a rectifier circuit, Fig. 5, a capacitor 5 is charged during one half cycle via capacitor 3 and diode 4 and during the other half cycle via capaciter 3a and diode 4a, to a potential determined by Zener diode 9. When sufficiently charged, thyristor 6 or 6a is fired to switch thyristor 1 or la in the bridge rectifier. In order to prevent the thyristor 6 being fired until sufficient voltage has developed, the control circuit of thyristor 6 may include a Zener diode coupled to the capacitor, 5 via a transistor, Fig. 3 (not shown). The Zener diode 9 may be connected to the other side of the diode D. In place of the thyristor 6 a trigger diode (16), Fig. 6 (not shown), a transistor, or a light sensitive device, may be employed. In a further modification, Fig. 4 (not shown), the diode 4 and capacitor 5 are shunted by a diode (13) in series with a resistor (12) to suppress voltage transients. In a still further embodiment, Fig. 8, the control input signal circuit is modified so that the input signal, e.g. a pulse train, applied to terminals 10, 11 is applied to thyristor 1 as well as to thyristor 6. In order to allow capacitor 5 to recharge if the first control pulse fails to fire the thyristor 1, the thyristor 6 is blocked by transistor 31. The trigger drive to thyristors is applied via capacitor 35 to delay the switching of transistor 31. This modified form of drive prevents indeterminate triggering which may damage the device 1 when using an inductive load. The capacitor 5 may be replaced by a secondary cell.

Abstract: 1,271,801. Change-speed control. C.A.V. Ltd. 6 Oct., 1969 [15 Oct., 1968], No. 48843/68. Heading F2D. In a motor vehicle transmission in which speed-ratios are established by energizing individual solenoids S 1  ... S 5 , through switches G 1  ... G 5 , possible damage due to simultaneous energization of more than one solenoid is avoided by switching off a transistor T 1 , which is normally maintained conductive, by a resistor R 3  to supply all the solenoid switches G 1  ... G 5 , switch off being in response to the sensing of voltage at a common point 12 connected directly to each of the solenoids through a resistor R 11  ... R 15  respectively. Potential at the common point 12 is applied to the base of a transistor T 3 , the emitter of which is connected to potentialdividing resistors R 1 , R 2  across the supply poles 10, 11 (10 is negative as shown). When only one gear solenoid S 1  &c. is switched on, one resistor R 11  &c. is in series with all the remainder in parallel and the voltage at 12 is such that the transistor T 3  is non-conductive. With two solenoids switched on, two resistors R 11  &c. in parallel are in series with the remainder in parallel and the voltage at 12 is rendered sufficiently positive with respect to the negative pole 10 to render the transistor T 3  conductive through resistors R 4 , R 6 , which in turn renders a transistor T 2  conductive, zeroizing the base-emitter potential of the transistor T 1 , which thereby ceases to conduct, deenergizing all the solenoids. The transistor T 3  is maintained conductive through a resistor R 5 , so that the transistor T 1  remains non-conductive until the supply is discontinued. A capacitor C 1  and diodes D 1 , D 2  provide discharge paths and delay, to avoid action due to transients and surges. In Fig. 2, not shown, the polarity of the supply 10, 11 is reversed; transistor T 1  is now a NPN, and T 3  a PNP instead of the reverse shown in Fig. 1; an additional transistor (T 5 ) is associated with the transistor T 1 , and an amplifying transistor circuit (T 4 ) is provided between T 3  and T 2 ; and there is a latching circuit comprising a resistor (R 11A ) and diode (D 4 ) between the common point 12 and the base of T 1 , together with a further diode (D 3 ) between the collector of T 2  and base of T 1 . This maintains the transistor T 3  conductive after T 2  has switched off T 1 .

To form a thermocouple radiation detector two metals or alloys are deposited by vacuum deposition or cathodic atomization on to an electrically insulating film 10 supported between two insulating bars 11, 12. The deposits from a series connected assembly of thermo-electric junctions lying alternately on opposite sides of the centre line of the film. In one embodiment the reverse side of the film, which in use is to be exposed to radiation, is coated on one half with a material having a low coefficient of radiation absorption and on its other half with a material such as platinum black or gold black having a high absorption coefficient. In use a strip screen 21 prevents radiation from falling on the centre line of the assembly. It is stated that the output voltage is substantially proportional to radiation density and is independent of the ambient temperature. The detection may be used in free air but it is preferably mounted in a sealed container filled with gas at low pressure. The detector described has an I.R. transparent window sealed into a metal container provided with heat dissipating fins. In the modified detector of Figures 4 and 6 (not shown) the entire reverse side of the film is coated with gold black or platinum black Radiation is allowed to fall in turn on each of the halves of the detector so that an alternating potential is generated. Chopping is achieved by a rotating vane pivoting about an axis on one of its edges, the axis being transversely mounted in the centre of the incident beam. The detector may be cooled by the air flow from the rotating vane but in an embodiment in which the detector is mounted within a non- finned metal container air is forced between this and a surrounding tube by centrifugal fans mounted on the same driven spindle as the rotating vane. When the response time of the detector is shorter than the time for which each of its halves is exposed an alternating potential is produced the RMS value of which is proportional to flow density and independent of ambient temperature.
