Abstract: 1,091,298. Homopolar and other rotary machines. J. GRAY. Aug. 5, 1966 [June 9, 1965], No. 24314/65. Heading H2A. A dynamoelectric machine comprises a shaft, magnetic means on the shaft for producing an axially-directed magnetic field, and an electrically-conductive rotor of sufficiently large radial magnitude for interception of the total magnetic field, with means (preferably radiallyspaced brushes) for tapping electric current from, or supplying it to, the rotor. In one embodiment for generating, or motoring on, D.C., a circular permanent-magnet disc, magnetized axially, has a copper disc rotor of the same size secured concentrically to one of its faces, e.g. the N face, the whole being mounted on a shaft and rotated. Two brushes in contact with the exposed face of the rotor-one near the shaft, the other near the peripheryprovide the output or input connections. In an alternative, the rotor " disc " is in the form of five spaced sectors, with two radially-spaced brushes for each sector. The inner brush of the first sector is connected to the outer brush of the second sector and so on around the rotor, the first outer brush and the last inner brush providing the external connections. An A.C. machine is produced by dividing the permanent magnet disc of the first embodiment along a diameter, reversing one half, and rejoining the two halves so that their polar directions are opposed. The rotor is then secured to it as before. The brushes in this case are at opposite ends of a diameter. In an alternative A.C. embodiment, as shown, the single permanentmagnet disc is replaced by two half-diameter, oppositely-polarized, discs 2, 3. In all cases a D.C.-energized electromagnet may be used instead of a permanent magnet.

Abstract: 1535399 Controlling spray carburetters NISSAN MOTOR CO Ltd 14 June 1976 [13 June 1975] 24487/76 Heading F1H An I.C. engine comprises a carburetter including a main well 22, Fig.1, communicating via a main discharge nozzle 20 with a Venturi 18 disposed upstream of the throttle valve 12 and also communicating via a main jet 30 with the float chamber 28; a main bleed orifice 24 and an additional air passage 32, see also Fig.2, both providing air bleeds between atmosphere and the main well; a passage 38 containing a restrictor 38a and interposed between portions 32a and 32b of the additional air passage; a valve 36 for closing a passage bypassing the restrictor 38a so as to reduce the flow of air through the additional air passage; and a control circuit 40 for controlling the opening and closing of the valve in accordance with a composition of the exhaust gases indicative of the air/ fuel ratio of the mixture fed to the combustion chamber, whereby the air/fuel ratio is controlled to a predetermined value. The composition of the exhaust gases is sensed by a sensor 42 in the exhaust passage 44, the sensor sensing the concentration of O 2 , NO x , CO, CO 2  or HC in the exhaust gases. The valve 36 may be an electromagnetic valve comprising a movable member 58 co-operating with a valve seat 54 and secured to a diaphragm 52. The electromagnetic valve is operated in pulsed mode with a variable energization time ratio. When a catalytic converter 46 capable of reducing NO x  as well as oxidizing CO and HC in the exhaust gases is used, the predetermined value to which the air/fuel ratio is controlled is the stoichiometric one, to ensure efficient operation of the converter. While the invention is shown as applied to the main circuit of the carburetter, it may also be applied to the low-speed circuit.

Title: An improved table lighter
IPC: F23Q2/08
Filed: 1946-08-16
Abstract: 615,035. Frictional igniters. GOLDSTEIN, M. Aug. 16, 1946, No. 24503. [Class 75 (iii)] A table lighter comprises a push button adapted, when depressed, to move the snuffer off the wick end and to compress a spring for rotating the flint wheel, a delayed action device for subsequently releasing the said spring to rotate the flint wheel, and means for returning the snuffer when the push button is released. When the operating button 9 on the plunger 8 is pressed down, a plate 12 compresses a spring C against a shoulder on a pin 7 and a spring D against a block 5 which guides a slide 10, which is engaged with a recess in the pin 7 by the action of springs E. Towards the end of its downward movement a cam portion of the plunger 8 moves the slide 10 to disengage the pin 7 which is moved suddenly downwards by the action of the spring C. The pivoted snuffer arm 4 is thereby suddenly rotated about its pivot 15 by the engagement of a forked member 6 with pins 16, and at the same time the flint wheel, which is also mounted on the pin 15, is rotated with the arm 4 by a ratchet in the form of a split washer spring. The pin 7 is maintained in its lowest position to keep the snuffer arm 4 open, by the engagement of the slide 10 with a shoulder above the tapered portion of the pin 7, whilst the plunger 9 is returned by the spring D. To close the snuffer arm the pin 7 is released by pressing a button 11. In a modification the button 11 is not included and the snuffer is closed as soon as the operating button 9 is released. Reference has been directed by the Comptroller to Specification 615,165.

Patent GB-845315-A (GB)
Title: Continuous process for the production of yeast
Inventor: SHER HARRY NATHAN
IPC: C12N1/16
Filed: 1957-08-03
Abstract: In a continuous process for growing yeast e.g. baker's yeast under conditions of aeration, fermentation is effected in two or more, preferably 3 to 6, fermentation vessels, to the first of which is added yeast, nutrients and water, yeast being continually grown and further nutrients and water added to this vessel until the desired quantity of yeast and medium is obtained, whereupon, whilst continuing to grow yeast and add nutrients and water yeast-containing medium is continuously transferred to the second fermentation vessel so as to maintain the yeast cell concentration and volume of medium in the first vessel constant at the desired level, there being then added to the second vessel nutrients and water to grow yeast in it, the volume of medium and yeast cell concentration being kept constant by continuously transferring yeast-containing medium either to a further fermentation vessel or vessels in each of which the same procedure is repeated, or, alternatively, to a ripening vessel in which ripening conditions are maintained and from which yeast cells are subsequently recovered by filtration, the conditions of fermentation and the transfer rate between vessels being so controlled as to provide a rate of yeast production per unit amount of yeast in the range 0,05 to 0,20, most suitably between 0,075 to 0,175.  The nutrient is an aqueous solution of molasses, ammonium hydroxide and ammonium sulphate; diammonium phosphate is preferably added to the first vessel only to give yeast containing 2,0 to 2,8% phosphate as P2O5 based on the yeast dry matter.  Preferred conditions for all fermentation vessels, except the last, are: temperature 75 DEG  to 92 DEG F., pH 3,0 to 5,5, grams assimable nitrogen per 100 grams molasses added 0,50 to 4,0, whereas for the last they are, respectively, 90 DEG  to 95 DEG F., 4,5 to 5,5, and 0,0 to 0,07. In the ripening vessel no or fewer nutrients are added and the aeration rate is less than that effected in the fermentation vessels.  An alternative starting procedure comprises seeding nutrient medium in the first vessel with yeast, thereafter adding nutrients and water and aerating, and continuing as before.  The process may be terminated by either stopping transfer of yeast containing medium between vessels and ripening the yeast in each, or by allowing the vessels to empty themselves commencing with the first.  The desirable rate of production of yeast for any vessel when the process is operating steadily and continuously is substantially equal to the maximum rate achieved during starting up in that vessel.
