Title: Improvements in or relating to vehicle lighting systems incorporating a generator and a voltage regulator
IPC: H02J7/16
Filed: 1960-11-11
Abstract: 962, 987. Automatic voltage control. ROBERT BOSCH G.m.b.H. Nov. 11, 1960 [Nov. 23, 1959], No. 38738/60. Heading G3R. [Also in Division H1] A voltage regulator for the generator 10 of a vehicle lighting system comprises a power transistor 40 which is connected to the generator field winding 14 and which is controlled by a second transistor 41 having its base connected over a Zener diode 43 to a potential divider bridge 45 connected across the output leads 16, 18 of the generator, the potential divider containing a temperature sensitive resistor 48 thermally associated with a rectifier 52 in one output lead. When the generator 10 is driven the voltage between the leads 16, 18 builds up to a value Ug, e.g. 28 V, and a current J L  flows to charge a battery 15. Should the generator voltage tend to increase above the value Ug the voltage Us effective at the tapping point 51 of the bridge 45 becomes greater than the breakdown voltage of the Zener diode 43 which thus conducts a control current J S  from the base of transistor 41, whereby transistor 41 becomes conductive and initiates a control action, through the intermediary of a transformer 57 and condenser 61, to block transistor 40 so that the field current, and hence the output voltage of the generator, is reduced. Should the current increase beyond the admissible maximum value, e.g. by the switching in of an additional device 64, the temperature of the rectifier 52 carrying the increased load current will rise and the resistance of the associated resistor 48 will also rise, causing a rectifier 51 in the diagonal of the bridge 45 to conduct whereby the Zener diode 43 will also become conductive so that the regulating action becomes effective before Ug reaches its normal operating value of 28 V. The system is thus protected against a temperature rise which would cause the rectifier 52 to lose its rectifying action.

Abstract: 1,002,762. Folding tables. EDWARD DOHERTY & SONS Ltd. Nov. 13, 1961 [Nov. 11, 1960], No. 38815/60. Heading A4H. A folding table has legs 2, yoked together in pairs at 3, which are attached to the table top 1 by pin and slot hinges and are urged into their extended position, as shown, or into the inwardly folded out-of-use position by a flat spring 15 secured at 16 to the top 1 and having up-turned lugs 17 which help to prevent the legs 2 from splaying outwards. Each hinge comprises a slotted element 8 riveted to the top 1 through lugs 12, and flat-sided bars 11 passing through the slots 9 and fixed to the yoke 3. The lower part of the slot 9 is enlarged as at 10 to permit the bar 11 to rotate when the legs 2 are folded inwardly, handles 4 projecting through openings 5 in the top 1, and hand-grips 6 formed in the top being used together in erecting or collapsing the table. The slot portion 10 may have projections which restrict the inward rotation of the legs. Specification 816,952 is referred to.

Abstract: 1283964 Transistor biasing RCA CORPORATION 5 Aug 1969 [12 Aug 1968] 39128/69 Heading H3T In a circuit arrangement the collector emitter path of a biasing transistor 18 and a resistor 50 are connected in series between a point 26, connected to receive D.C. through a relatively high resistance 36, and a point 32, a coupling between the emitter 12 of an amplifying transistor 10 and the point 32 is less impedance than the resistor 50, a resistor 28 is connected between the point 26 and the base of the transistor 10, a resistor 30 is connected between the collector and base of the transistor 18 to provide the sole source of base bias to the transistor 18 and the arrangement is such that the transistor 10 operates with a higher collector current than that of the transistor 18. In order to obtain a predetermined ratio m of the collector currents through the amplifier and biasing transistor sections 10 and 18 the variation in value of resistor 30 required, to compensate for manufacturing tolerance variation of the forward current gain #10 of transistor 10, is reduced or eliminated by incorporating a suitable value emitter resistor 50. The circuit may be an integrated circuit and the biasing transistor 18 compensates for temperature variations. In a prior art circuit (Fig. 1, not shown), each transistor 10, 18 may be in common emitter mode or each may have an emitter resistor. In a further prior art circuit (Fig. 2, not shown), the amplifier transistor (10<SP>1</SP>) consists of ten parallel connected transistors.

[Also in Division B3] A sheet slitter for cutting sheets during conveyance from a printing press, comprises a cutting disc 5 positioned in the delivery path of travel of the sheets, means 7 ... 10 to rotate the disc and sharpening means 13, 14 adapted to engage the cutting surface of the disc to maintain a cutting edge on the disc without stopping the press or removing the disc therefrom. As described, the disc is rotated by a motor 10 via gearing 7, 8. On opposite sides of the disc are support blocks 11, 12 carrying the spindles of the grinding wheels 13, 14, which are each mounted so that one face is resiliently urged, as by a variable spring 17, against the bevelled cutting surface of the disc. The wheels 13, 14 are freely rotatable and are rotated by the disc 5, the line of contact between the disc bevel and the face of the grinding wheels being slightly offset to a line drawn through the spindle centres of the grinding wheels, so that a slight sliding motion is imparted between the wheels and the disc surfaces. The amount of sliding motion (which performed the grinding action) can be adjusted by varying the degree of offset of the contact line between grinding wheels and disc. A felt pad may lightly brush and clean the disc 5.

Title: Tomography scanning
IPC: G01N23/08
Filed: 1977-09-26
Abstract: A fan-shaped beam (13) of hard radiation is emitted from a radiation source (11). This fan-shaped beam penetrates an examination region (14) and then impinges on a row of detectors (16) in which the radiation values corresponding to the transparency in the cross-section of the examination region are detected. The detectors (16) are situated on a circular track concentrically relative to the axis of rotation of the radiation source (11), and thus receive as they rotate a sequence of measured data for specific cross-sectional regions in each case, which are displayed via evaluation devices (17, 21). This device permits high-power scanning with a high resolution, there being no need for precise matching of the amplification between the individual detectors. It is possible for the detectors to be routinely calibrated without the patient having to leave the measurement region. <IMAGE>

Title: Voltage controlled oscillator
IPC: H03K4/50
Filed: 1970-08-21
Abstract: 1318251 Oscillator circuits; pulse modulation circuits GENERAL ELECTRIC CO 21 Aug 1970 [21 Aug 1969] 40363/70 Headings H3T and H4L In a voltage-to-frequency converter of the type in which a capacitor is charged through a transistor at a rate determined by the voltage applied to its base and in which alternate charge and discharge is caused by a comparator receiving the voltage across the capacitor, switching means is provided for preventing operation when the input voltage is of a value which cuts off the transistor. Operation due to leakage of the capacitor charge is thus avoided. A capacitor 3 charges through transistor 28 until its voltage reaches the reference value 35 at the input of a comparator 8. The output of the comparator then switches to render conductive a discharging transistor 14 and raise the threshold value at 35. The capacitor therefore discharges to the new threshold whereupon the comparator restores the next cycle initiated. The charging current and thus the oscillation frequency is controlled by an input signal source A via an operational amplifier 20 having a feedback circuit 30. In order to prevent oscillation due to capacitor leakage when the input signal to negative and the charging transistor is off, a switch 46 may be thrown to introduce a NAND gate 13. This has one input derived from a transistor 16 controlled by the input signal such that when the signal is negative, transistor 17 is off and its output inhibits control of the gate by the oscillator output. In Fig. 3 (not shown) the reference input (35) to the comparator is derived from the output of the amplifier (20) so that discharge is initiated when the charging transistor saturates. Inhibition when the input signal is negative is effected by a transistor (56) connected to the base of transistor 10 and controlled at its emitter by the output of amplifier 20. An F.E.T. may be connected between the collector of the charging transistor and the capacitor.
