Title: Motor vehicle battery charging system
IPC: H02J7/14
Filed: 1975-04-11
Abstract: 1499175 Battery charging systems DUCELLIER ET CIE 11 April 1975 [24 April 1974] 14917/75 Heading H2H A motor vehicle battery charging system includes an indicating lamp, which may be a light emitting diode, which is illuminated under two conditions which are when the battery charging voltage is below a first predetermined value and when the charging voltage is above  a second, higher, predetermined voltage. Closure of an ignition switch 14 causes breakdown of a zener diode 30 and with an alternating voltage generated at the alternator terminal 13, the base potential of a transistor 28 is such that the transistor is conductive which causes a second transistor 19 to become conductive to illuminate an incandescent lamp 17 to indicate that the output voltage of the alternator is insufficient to charge a battery 12. As the speed of the alternator increases, the output voltage thereof increases until it reaches a value at the terminal 13 which causes transistor 28 to become non- conductive and hence transistor 19 also becomes non-conductive so extinguishing the lamp 17. If, due to a fault condition, the voltage applied to the battery becomes excessive, a zener diode 22 breaks down whereupon the transistor 19 again becomes conductive to re-illuminate the lamp 17 to indicate the existence of the fault condition. In other embodiments the lamp 17 may be replaced by a light emitting diode connected in parallel with the transistor 19 or a third transistor may be used, one of which is controlled by the output from the exciter 15.

Abstract: 1,164,793. Machinery guards. PHOTAIN CONTROLS Ltd. 4 April, 1967 [5 April, 1966], No. 15049/66. Heading F2J. [Also in Divisions G1 and G4] A photo-electric apparatus for detecting an object comprises a source of radiation irradiating a detector whose output is fed back to the source to cut it off thereby maintaining the apparatus in oscillation so long as the radiation is not cut off by the object or alternatively the detector is not continuously irradiated by a foreign source; loss of the oscillation initiates a control action. The apparatus is applicable to burglar alarms and machinery guards. In the embodiment the alternating output of a photo-diode operates a transistor trigger circuit to repeatedly turn on and off a transistor having the radiation source in its collector circuit. A mono-stable circuit capacitively coupled to this latter transistor is maintained in an astable state so long as the oscillations are maintained, but releases a relay to perform the control action if allowed to revert back to its stable state due to the loss of oscillations by an object obscuring the photo-diode, failure of a circuit component or continuous illumination of the photo-diode.

Title: Polymerization of vinyl fluoride
Inventor: MANNO PETER JOSEPH
IPC: C08F14/20
Filed: 1961-04-26
Abstract: A method of polymerizing vinyl fluoride comprises forming a dispersion of vinyl fluoride and a liquid in which the polymerized vinyl fluoride is substantially insoluble, subjecting the resulting emulsion to gamma radiation at a pressure below 1,000 p.s.i.a., and recovering polymerized vinyl fluoride.  Specified liquids are water, benzene, toluene, aliphatic alcohols and ketones, sulphonated aliphatic and aromatic hydrocarbons, and C5-14 aliphatic hydrocarbons.  The radiation intensity may vary from 1X104 to 1X107 reps.  The molecular weight of the polymer varies according to the liquid used, thus water containing dodecylbenzene sulphonate leads to higher molecular weight polymers than aromatic and aliphatic hydrocarbons.  Specification 774,897 is referred to.

Abstract: 1,271,072. Controlling mixing operations. E. H. BENTALL & CO. Ltd. 24 March, 1969 [22 Dec., 1967], No. 15395/69. Divided out of 1,271,071. Heading B1C. . In an electrical control system (see Figs. 4-6, not shown) for a cereal grain milling and mixing plant, there are sensing means responsive to the mixing operation in the mixer and to the discharge operation, which interrupt the timer cycle motor (but not the mixer timer motor) at the beginning of the mixing operation or of the discharge operation, and allow it to restart on the completion of the operation. As described the plant (see Figs. 1-3, not shown) comprises a plurality of grain silos delivering in succession to weigh batches and thence to a mill and a mixer. The cycle timer consists of a plurality of cam-operated switches, and the cycle consists of one revolution of the timer cam shaft and is arrested by interrupting the current to the motor. When preset quantities of each cereal have been delivered to the mill the controller switches off the mill and starts the mixer which is allowed to run for a preset time, after which it is stopped and a discharge slide opened; when gravity discharge ceases a sensor in the discharge pipe operates a flow switch which provides a signal to re-start the mixer whereby the residual cereal is expelled therefrom. The cycle can be automatically repeated a pre-set number of times.

Abstract: 612,448. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 22, 1946, No. 15459. Convention date, May 22, 1945. [Class 40 (v)] Angle-modulated carrier waves are demodulated by deriving therefrom a resultant which has a variable degree of asymmetry dependent on the frequency deviation and applying the resultant wave to balanced rectifiers. In Fig. 1, an I.F. stage 1 feeds an harmonic generator 2, which may also function as a limiter, and which has a pair of anode resonant circuits 9, 10 tuned respectively to an harmonic, say the second, and to the fundamental intermediate frequency. The circuits 9, 10 are coupled to similar tuned circuits 11, 12 which are connected in series with oppositelypoled rectifiers 13, 15 and with a load resistor 19. The combined voltage across the circuits 11, 12 is of complex waveform which becomes asymmetric as the frequency deviates from a mean value owing to the relative change of phase between the fundamental and the harmonic. The difference between the rectified voltages obtained from the positive and the negative portions of the resultant wave is registered across the resistor 19 and constitutes the detected signal. Delay bias 17 is applied to each rectifier to prevent operation at low input voltages. In a modified rectifier circuit, Fig. 6, a separate load resistor 22, 24 is provided for each diode, and the audio signal is taken from a central tap on a resistor 23 connecting the non-earthed ends of the resistors 22, 24. In Fig. 7, the secondary circuit 12 for the fundamental frequency is omitted, and the asymmetric voltage wave is taken across the primary 10 and the secondary 11. It is applied to deflecting plates 32, 33 on a C.R. tube 30 and swings the beam so that oppositelyvarying currents are received by the shield electrode 37 and the anode 38. The audioamplifier is coupled to the anode 38.
