Title: Method of obtaining intrinsic factor
Inventor: MANKOWSKI ADOLF
Filed: 1961-11-14
Abstract: The intrinsic factor is isolated from hog stomachs by subjecting the fresh or previously frozen ground hog stomachs and/or hog duodenum at room temperature to the action of about 2% aqueous solution of sodium chloride, applying at the same time stirring or shaking, separating the insolubles, adjusting the pH of the aqueous solution to 3.0 with hydrochloric acid, again separating impurities, adjusting to pH 5 to 6 with aqueous sodium hydroxide, adding crystalline ammonium or sodium sulphate to precipitate the intrinsic factor, which after several hours storing in a refrigerator, is centrifuged, pressed and dried at room temperature.  The solution obtained after the removal of impurities at pH 3.0 may be further purified by adjusting the pH to 10 by the addition of sodium hydroxide followed by the addition of hydrochloric acid to pH 1.6 and separating the impurities therefrom. The solution is then adjusted to pH 5-6 and treated as above to precipitate the intrinsic factor.  Prior to the above, the stomachs may be treated with aqueous hydrochloric acid to pH 2 to 4, the clarified extract adjusted to pH 5.0 and the intrinsic factor precipitated with a 15% aqueous solution of ammonium or sodium sulphate.

Title: Improvements in or relating to a free piston engine
IPC: F02B71/06
Filed: 1958-12-17
Abstract: 889,509. Free piston compressors and gas generators. BURION, E. P. Dec. 17, 1958 [Dec. 20, 1957], No. 40756/58. Classes 7(1) and 7(2). A free piston engine comprises two similar movable assemblies displaceable in opposition and each including two motor pistons associated with a compressor piston which is provided with at least one jacket delimiting a cylinder for a fixed piston, the fixed piston serving to enclose a charge of gas in the cylinder to thus form a power accumulator in which the gas is compressed during a driving stroke so that the movable assemblies are brought towards each other after the driving stroke which latter occurs during combustion in two parallel motor cylinders enclosing the motor pistons of the two movable assemblies. As shown the two cylinders 5 and 6 communicate with each other at their middle part via a chamber 11 into which an injector 12 injects. Injection by the injectors 13, 14 occurs primarily and injection into the chamber 11 by the injector 12 occurs later. The injector 12 may be omitted. The fuel pump may be worked off the synchronizing mechanism. A by-pass from the fuel pump cylinder may be regulated according to the compression pressure of the engine. The left hand piston assembly comprises two driving pistons 35, 36 and a compressor piston 37. The piston 37 comprises cushion cylinders 38, 39. The right hand piston assembly is similar to the left hand assembly. The pistons 35, 36a may be slightly longer than the pistons 36, 35a so that the scavenging ports 7, 7a are slightly closed before the closing of the exhaust ports 8, 8a. The scavenging ports may be nearer the piston than the exhaust ports. The pistons 35 and 36a can be of slightly different lengths to improve scavenging in the chamber 11. The cushion pistons may be mounted as shown in Fig. 1 or rigidly mounted (Fig. 5). In Fig. 5 the interior of the pistons is air-cooled. The amount of return power of the cushion cylinders may be varied by known means. As shown in Fig. 3, the synchronizing mechanism may comprise a rack 48 which is integral with the cushion cylinder 39. Alternatively the synchronizing mechanism may comprise a system of connecting rods and cranks.

Title: Improvements in or relating to arrangements for the reproduction of magnetically recorded television signals
IPC: H03D3/24
Filed: 1963-10-21
Abstract: 1,019,504. Playing back television tapes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 21, 1963 [Oct. 24, 1962], No. 41479/63. Heading G5R. [Also in ivision H3] To reduce the visual impact of drop-outs and like playback faults, the F.M. carrier reproduced from a magnetic tape directly synchronizes a locked-in oscillator 3 whose frequency modulated output is then detected by a discriminator 6 and a D.C. control voltage is also applied to the oscillator to vary its natural frequency in the direction of the F.M. deviation and increase the control sensitivity, so that during any period of fading or no F.M. signal, a momentary constant D.C. output, e.g. a grey stripe, is reproduced. This control voltage may be derived from the discriminator through a delay, e.g. R-C time constant network, or from a second playback head 12 and discriminator 13 reproducing a signal delayed or advanced relative to the signal being reproduced by one or more line or frame periods, or in the latter case, plus or minus a half line period. Alternatively, an acoustic delay means may replace the delay network. The oscillator may be a transistor multivibrator of rapidly varying frequency response, as described in Specification 1,019,503.

Title: Bit sync recovery system
IPC: H04L7/033
Filed: 1968-08-30
Abstract: 1,237,422. Automatic phase lock. XEROX CORP. 30 Aug., 1968 [1 Sept., 1967], No. 41560/68. Heading H3A. In a data transmission system, local clock signals are synchronized with the transmitted data rate by generating local pulse signals at a multiple of the transmitted band rate, counting the number of pulses occurring within one band time, adding or deleting a pulse according to whether more or less than half the number of clock pulses have been counted at a sampling time, and dividing the pulse signal to generate the required local clock signal. The synchronization system is applied to a data transmission system in which the data signals may have one of four discrete levels, Fig. 2, and in which transitions of the signals past slicing levels are detected and are applied to unit 318, Fig. 3. A master clock input signal at a frequency 192B, where B is the band rate, is applied to a divider chain 301, 303, 305, 307 from which the required clock signal at rate B are obtained, and the timing of these pulses is shifted in steps of # band period, Fig. 8 (not shown), by adding or deleting pulses at unit 309 where the pulse frequency is 32B. Signals at 16B are passed via timing pulse generator 311 and control box 313 to counter 319, in dependence on transitions detected by counter 315. If no transitions occur, no signal is passed; if one transition occurs signal T 1  is passed; if two transitions occur T 1  and T 2  are passed; if three transitions occur T 1 , T 2  and T 3  are passed. Thus 16, 32, or 48 pulses are fed to the counter 319 in one band time unit. The early or late decision box 317 samples the reading of counter 317 whenever a sample pulse occurs. If no transition occurs, no signal is passed to flywheel unit 321; if one transition occurs and the position counter 319 is less than 8 the down line is pulsed, if the position counter is more than 8, the up line is pulsed. Similarly with two or three transitions the unit 321 is pulsed when the count differs from 16 or 24 at the sampling instant. Unit 321 is a further counter to which one is added whenever the "up line" is pulsed, and one is subtracted whenever the "down line" is pulsed. If the count in unit 321 is + 3 and the "up line" is pulsed, then a pulse is added to the 32B pulse train in 309 and the counter 321 is cleared. Similarly if the count is - 3 and the "down line" is pulsed, a pulse is subtracted from the train in 309.
