Patent GB-785014-A (GB)
Title: Process for the resolution of dl-serine
Filed: 1955-05-09
Abstract: The invention comprises N-3 : 5-dinitrobenzoyl - D - serine, its salt with D(-) - threo - 1 - p - nitrophenyl - 2 - aminopropane - 1 : 3 - diol, the salt of N - 3 : 5 - dinitrobenzoyl - L - serine with L(+) - threo - 1 - p - nitrophenyl - 2-aminopropane - 1 : 3 - diol, and a process for the resolution of DL-serine by reacting L(+)- or D(-) - threo - 1 - p - nitrophenyl - 2 - aminopropane - 1 : 3 - diol as resolution agent with N - 3 : 5 - dinitrobenzoyl - DL - serine in a solvent medium, one of the two enantiomorphs of the racemic serine derivative giving rise to a sparingly soluble salt with the resolution agent, separating the salt and liberating the N-3 : 5-dinirobbenzoyl - D - or L - serine therefrom and hydrolysing it to obtain D- or L-serine.  The L(+)-resolution agent forms a sparingly soluble salt with the L-serine derivative; the D(-)-resolution agent forms a sparingly soluble salt with the D-serine derivative.  The N-3 : 5-dinitrobenzoylserine is liberated from the salt by treatment with aqueous caustic alkali, filtration of the resolution agent and acidification of the filtrate.  The optically active serine is then obtained by acid hydrolysis.  The solvent medium may be an alcohol of 6 carbon atoms or less such as methanol and may contain a second solvent miscible therewith but immiscible with water such as ethyl acetate.  The enantiomorph which is not separated as a sparingly soluble salt may be recovered by extraction of the filtrate with aqueous acid to remove the resolution agent and precipitation with petroleum ether.  It may be recrystallized or reprecipitated with the corresponding resolution agent and hydrolysed to the optically active serine, or hydrolysed and the serine racemised and re-resolved.  The N-3 : 5-dinitro-benzoyl-serines may be prepared by reacting 3 : 5-dinitrobenzoyl chloride with serine or a derivative thereof such as an ester or ether from which the N-acyl-serine may be regenerated. Examples are given. Specifications 745,097, 785,012 and 785,013 are referred to.

Title: Improvements in and relating to doughnut frying machines
IPC: A21C15/04
Filed: 1940-08-26
Abstract: 543,772. Endless conveyers. LOWE CORPORATION, J. Aug. 26, 1940, No. 13461. Convention date, Oct. 7, 1939. [Class 78 (i)] [Also in Group VI] In a doughnut machine wherein the doughnuts, formed by a cutter 126 and dies 116, fall into a kettle 100 containing frying fat and are received between cross flights 110 of a conveyer extending substantially the whole length of the kettle, a single turnover device 111 arranged about mid-length of the conveyer and rotated by the flights thereon operates to turn over the doughnuts in succession, transferring each one from the space between one pair of flights into the next space in advance. Heating means for the kettle is supplied to transverse stiffening tubes 104 from which the conveyer sprockets 106, 107 are carried by brackets 135. The lower run of the conveyer is led round guide rolls 142, 144 arranged at the lowest part of the kettle. The turner 111, Fig. 8, has four blades 112 with flanges 117 to embrace the doughnut which is supported on, and tripped by a plate 131 when being turned over by a conveyer flight acting on a spring plate 132 arranged adjacent each blade. Each doughnut is drawn over and supported by a resilient plate 128 as it approached the turner. After leaving the main conveyer the doughnuts may be carried by an auxiliary conveyer 122 to a delivery shoot 125.
Patent GB-441439-A (GB)
Title: Improvements in gyroscopes
IPC: G01C19/44
Filed: 1935-05-08
Abstract: 441,439. Gyroscopic apparatus. ALKAN, R., 70, Avenue de la RÚpublique, Paris. May 8, 1935, No. 13530. Convention date, May 9, 1934. [Class 97 (iii)] An erector for a gyro vertical comprises an auxiliary mass rotating about the axis of spin in the same direction as the rotor but at a reduced speed and driven by frictional engagement with the rotor, the pressure of the frictional engagement and therefore the speed of revolution of the mass being varied during each revolution in accordance with the inclination of the gyro. In the form shown a drum 10 is fixed to an extension of the rotor spindle 9 which also carries on ball bearings 11 a rotatable plate 12. A shoe 5 and a mass 4 are carried by a lever 20 which is pivoted to the plate 12 at 17 and acted on by the spring 16 to bring the shoe 5 into frictional engagement with the drum 10. A second lever 2 is pivoted to the plate 12 at 15 and carries a mass 3 and a shoe 1 adapted to bear on a cylindrical flange 13 fixed to the rotor casing 8. When the gyro is vertical and the plate 12 rotating, centrifugal force acting on the masses 4 and 3 tends to decrease the pressure of the driving shoe 5 and increase the pressure of the braking shoe 1 until the plate 12 rotates at a speed such that these opposite actions balance, this speed being substantially independent of the rate of spin. When the masses 3, 4 are subjected to an additional force, e.g. in the direction of the central arrow, due to inclination of the gyro or acceleration, the driving force is increased, the braking decreased, and the plate 12 rotated more rapidly until the latter has turned through 180‹ when the action is reversed. Thus the auxiliary mass 7, which is adjustably mounted on the plate 12 to enable the phase to be varied, is caused to hurry through half a revolution and linger on the other half thus giving rise to an erecting torque. A ball 18 is trapped in a cursor 19 which is adjustable along the lever 2 to enable the centrifugal moment applied to the latter to be varied. A number of balls may be free to move in the trough formed by the flange 13 and top of the casing 8 and, when the gyro is inclined, bear against the lever 2 during one half of a revolution. In a modification the shoe 1 may be replaced by a roller 61, Fig. 3, the rotation of which is resisted in proportion to its speed by an escapement wheel 62 engaging a pivoted unbalanced weight 63, by an eddy current brake or by blades rotating in air. The displacement of the mass 7 is arranged to cause a slight permanent oscillation of the gyro. The driving current for the rotor is led through the gimbal axes.

Filed: 1975-04-03
Abstract: 1466490 Analogue-to-digital conversion GENERAL MOTORS CORP 3 April 1975 [9 April 1974] 13608/75 Heading H3H In a digital multigauge for a motor vehicle, the engine temperature, oil pressure and fuel level control the resistances of respective sensors 60, 62, 64 through which a capacitor 66 is discharged to derive respective time intervals, digitized by counting pulses from oscillator 22 whose frequency depends on which of the sensors is currently discharging capacitor 66. A shift register 122 emits control signals W T , T, W P , P, W F , F for selecting the sensors, appropriate frequency-determining resistances 36- 46, and variable selected indicators 162, 164, 166. Normally, signals T and P (for displaying temperature and oil pressure) are suppressed by gates 126, 128 so that fuel level is continuously displayed at 14a, 14b, 14c, 166, while control signals W T , W P  and W F  test all three variables in turn, an out-of-limits counter 28 giving a "service" warning 20 if the temperature is too high or the oil pressure or fuel level too low, and causing the appropriate indicator 162, 164 or 166 to flash. Under manual control, using the "cycle" switch, gates 126, 128 pass control signals T, P so that the values of all three variables are displayed in turn. Also a continuous indication of the value of engine temperature or oil pressure can be ordered by closing switch 200 or 202.

Abstract: 578,716. Wireless receiving circuits; frequency modulation. COSSOR, Ltd., A. C., and BELL, D. A. July 24, 1944, No. 14091. [Class 40 (v)] A wanted signal frequency is separated from an accompanying interfering signal frequency of less strength by applying them to a limiter circuit together with a further oscillation of a third frequency, and by selecting from the limiter output that oscillation whose frequency is the image of the wanted frequency with respect to the third frequency. Applied to a wireless frequency-modulation receiver, the signals from the aerial are amplified by a radiofrequency amplifier RF, converted to an intermediate frequency by means of the frequencychanger FC and local oscillator L.O.1, and amplified by an intermediate-frequency amplifier I.F.1 in the usual manner. The signals are limited in amplitude by a first limiter L1 and are then applied to a second limiter L2, together with oscillations from the local oscillator L.O.2. The image-frequency signal occurring in the output from the limiter L2 is selected and amplified by a second intermediatefrequency amplifier I.F.2 and may be limited in amplitude by a further limiter L3, and detected by a discriminator D in the usual manner. The gain of the amplifier I.F.1 may be automatically controlled by control means A.G.C.1 of known type, and the same control potential may be applied over a connection A.G.C.2 in order that the amplitude of the oscillations from the oscillator L.O.2 may be regulated so as to be of the same order as that of the signal frequency oscillations at the limiter L2. The limiter L2 may comprise a pair of inversely connected diodes with delaying bias, or may comprise a pentode limiter or other known limiting means.
