Title: Production of butyl alcohol and acetone by fermentation
IPC: C12P7/28
Filed: 1941-07-11
Abstract: Organisms for the fermentation of molasses or other carbohydrate mashes to produce acetone and butyl alcohol are treated to render them immune to the filterable virus occurring in the mashes and at the same time to increase the proportion of acetone in the products of fermentation by repeated cultivation in a medium containing infusion of fresh liver, bactopeptone and glucose together with pieces of exhausted liver and with an addition of the virus in high concentration.  The organism is resistant to the virus after the second culture, but preferably 3 to 5 cultures are made, the transfers being made while the organism is in the vegetative state, the culture being finally allowed to sporulate and the spores transferred to sterile soil, dried and stored.  The proportion of acetone in the yield may be further increased by repeating the cultivation 9 to 15 times. The process is described in connection with the use of Clostridium Madisonii, an organism grown by pure culture methods from a sample of soil collected in the vicinity of Madison, Wisconsin, U.S.A. The bacteriological characteristics of the organism are given in detail.

Title: Improvements in or relating to hydraulic transmission arrangements for self-propelled earth-working vehicles
Inventor: KERSEY ALBERT HENRY
IPC: F16H61/40
Filed: 1955-03-25
Abstract: 767,650. Motor vehicle driving gear. FORD MOTOR CO., Ltd. March 25, 1955, No. 8834/55. Class 79(2). [Also in Group XXIX] In a hydraulic transmission system in which a pump supplies motors for propelling a vehicle an overload release valve is connected through a shuttle valve to the high pressure line, and on being opened when a pre-determined pressure is exceeded directs liquid to open a supplementary and larger valve in a by-pass between the pressure and return line. The supplementary valve remains open with the pump completely unloaded all the time the pump continues to deliver, and can only be reset, so that the motors may be actuated, by stopping the pump delivery. The pressure in lines 2, 3 acts upon the ends of a shuttle valve member 14 in a chamber 6 to move the member 14 so as to put whichever line 2, 3 is the high pressure line into communication with the chamber 6 so as to act upon a spring loaded release valve 25. By altering the position of a cam 30 which compresses a spring 26 loading the valve 25, the valve can be adjusted to open at any desired value of the pressure in chamber 6. When this pressure is exceeded, valve 25 is unseated and liquid flows through ports 22, an annular groove 23, and a passage 34 to the space above a piston 39. Piston 39 is depressed, unseating a valve 46 and uncovering a passage 51 so that liquid passes from the chamber 6 through the valve 46 and passage 51, past a non-return valve 52 to whichever line is the return line.

Abstract: 458,547. Gravity-separation apparatus. PARTRIDGE, H. E., 79, Craiglockhart Road, Edinburgh. March 25, 1936, No. 8837. [Class 46] A settling-tank divided into sections has means for directing the flow of liquid through any combination of the sections and conveyer means for the discharge of settled matter extending through the lower part of all the sections. Liquid, such as coal-washing water, is supplied by a trough 12 which is divided by partitions 13 with sluice gates 14 into passages, each of which delivers to one of the several sections into which a settling-tank 6 is divided by vertical transverse baffles 11. The liquid is caused to take a sinuous path in each tank section by means of baffles 17, 18, 19, 21 and flows away through a trough 23. There may be an overflow trough similar to the trough 23 on the opposite side of the tank. The solid matter is deposited on to a conveyer belt 25 which passes along the bottom of the tank below the lower ends of the baffles 11 and up the sloping end 9, and is discharged on to a heap 43 as the belt passes round a roller 26. Matter adhering to the belt is removed by scrapers 39, 40, and the belt passes round rollers 28 beneath the tank and a roller 30 at the other end. All the rollers are positively driven by a toothed chain engaging sprockets on the rollers. Means are provided for separately adjusting the tensions of the belt and chain. As firmer matter separating from the liquid promotes the retention of larger particles matter removed by the scraper 40 may be collected in a trough 15 and passed with the liquid under treatment to the tank. Modified apparatus is described in which the liquid after passing transversely through one or more sections of the tank is caused to pass in a longitudinal direction through a further section in which finer matter is deposited as an initial layer on the belt near its point of entry to the tank.

[Also in Division G4] The modulation phase change distancemeasuring system of the parent Specification is modified by incorporating a phasemeter having fine and coarse indications, the coarse measurement being disconnectible during a period when the modulation frequency remains at one value after its sweep from the other modulation frequency. In the embodiment the disc 3 driven from the motor of the phasemeter has teeth 6 and light bulbs 8, 9, Fig. 3, in front of the disc which register with slots 10, 11, Fig. 2, in a mask behind the disc. The amplified outputs from photo-cells 12, 13 are fed to respective monostable multivibrators 16, 17, and the outputs from multivibrator 17 pass to differentiators 18, 19 and 20, 21. Each time cell 13 becomes darkened a pulse is obtained from differentiator 18, 19 and each time cell 13 becomes lightened a pulse is obtained from the other differentiator. The outputs of AND gates 22, 24 and 23, 25 are connected as shown to OR gates 26, 27 which are connected to respective " fine " and " coarse " reversible counters 28- 30 and 31-35. Pulses from gate 26 actuate the counters forwardly and those from gate 27 actuate them in the reverse direction. AND gates 36, 37 are provided for switching the coarse counter out of circuit. Operation after a "zero-distance" reflector has been inserted into the wave path and a modulation frequency sweep has been executed to afford a " zero distance "measurement, the reflector is removed, the target reflexion is operative, and the fine counter is allowed to stabilize; finally, the coarse counter is rendered operative and a reverse modulation frequency sweep is effected. The counters then give object distance without error.

Abstract: 1527023 Television systems; variable delays EASTMAN KODAK CO 5 March 1976 [5 March 1975] 09000/76 Headings H4F and H4R An arrangement for removing phase variations in the time base of an input signal, e.g. the video signal from a video tape recorder, includes means for generating an error signal proportional to the phase variations, means responsive to the error signal to generate the reciprocal of the error signal, and means for controlling the delay time of a variable delay in response to the reciprocal signal, the input signal being fed to the delay to remove the phase variations. In the case of a frequencycontrolled storage-type delay line, e.g. a charge coupled device, the delay does not vary linearly with the frequency of the pulses controlling it: the arrangement described compensates for the non- linearity. In the embodiment illustrated, Fig. 2, the input video signal passes to the delay 22 and to horizontal sync. pulse separator 24. A phase lock loop 32, 30, 28 generates an error signal which is proportional to the phase difference between the sync pulses, which are undesirably varying in phase, and stable phase reference pulses generated by the voltage controlled oscillator 28. The error signal is filtered 36 and an inverter 38 forms its reciprocal. The reciprocal signal controls the repetition frequency of the signal generated by a voltage controlled oscillator 40, which in turn controls the delay 22.

Title: Manufacture of soluble acid calcium salts of inosite-phosphoricacid
IPC: C07F9/117
Filed: 1923-03-29
Abstract: Soluble acid calcium or calcium-magnesium salts of inosite phosphoric acid are prepared from alkali or magnesium compounds of inosite phosphoric acid by a direct or indirect process involving the steps of double decomposition with a calcium salt and precipitation of the acid salts with alcohol.  When a saturated or unsaturated alkali salt of inosite phosphoric acid forms the starting material, sufficient acid is added to the aqueous solution to form the acid salt, followed by the addition of a soluble calcium salt and the product precipitated with alcohol.  In the case when magnesium salts of inosite phosphoric acid comprise the starting material, several methods are available.  With a saturated magnesium salt, a sufficient amount of acid is added to form the acid salt before adding the soluble calcium salt and precipitating with alcohol; by using less than the equivalent quantity of soluble calcium salt, acid calcium-magnesium compounds of inosite phosphoric acid are produced. With saturated or acid magnesium salts, conversion into the saturated alkali salts may first be effected and these then treated as above, or the alkali salts are converted into the saturated calcium salts and acid added to form the acid salts which are precipitated with alcohol; alternatively the saturated or acid magnesium salts are first converted into the saturated calcium salts, acid then added to form the acid salts and these precipitated with alcohol.  Examples are given.
