Title: Improvements in or relating to alternator regulator systems
Inventor: GROLLET DUDLEY FRANCIS
IPC: H02J7/24
Filed: 1968-05-30
Abstract: 1,272,218. Automatic voltage control. MULLARD Ltd. May 12, 1969 [May 30, 1968], No.25967/68. Heading G3R. An automatic voltage regulator for a vehicle having an alternator A, rectifier A1, A2, A3, battery 26, ignition switch 5, a separate wire SW to sense the battery voltage and warning lamp WL, comprises a transistor T13 which intermittently energizes the field winding F of the alternator in accordance with the condition of a bi-stable circuit formed of a long tailed pair of transistors T2, T3, to whose bases are respectively applied signals representative of the battery voltage and a desired value thereof, the regulator being designed to exhibit hysteresis with respect to the battery voltage between turning on and off the field current to the alternator. The battery voltage signal is obtained from resistors 2, 3 through a transistor T1, whilst the desired value signal is obtained from a reference voltage derived from the emitter-base breakdown characteristic of a transistor T11, this voltage being applied to transistor T3 through the base-emitter of a transistor T9 or the emittercollector of a transistor T10 according to the state of the bi-stable circuit T2, T3. The operation of the circuit including members T1---T4, T9, T10 is analysed to show that the hysteresis voltage at the terminal B, which voltage corresponds to the two states of the bi-stable circuit (and hence to the ON and OFF conditions of the transistor T13), is independent of the values of the resistors 5, 6 and dependent only on the ratio resistors 2, 3. This feature obviates the need for close tolerance resistors and thus enables the regulator to be of solid state integrated circuit form. For this reason transistors T5, T7 are respectively combined with transistors T6, T8 to provide sufficient amplification of the signals transmitted thereto. Transistor T1 is chosen to provide voltage temperature coefficient compensation for that of the transistor T11 and may consist of a transistor with one or more diodes in series with the base-emitter path. Transistor T11 may have its collector or base left open-circuited, transistors T2, T3 may have compensating voltage-temperature coefficients and resistors 11, 14 are chosen to provide further temperature stability. Transistors T5, T6 control the Darlington-connected transistors T12, T13 and transistors T7, T8 compare the alternator and battery voltages to control an ignition warning lamp WL in the usual way. If the wire SW sensing the battery voltage should become disconnected, transistors T12, T13 are turned off to open circuit the field winding and so prevent build-up of the alternator voltage. Feedback in the regulator is provided by transistors T14, T15 and resistors 12, 13.

[Class 94 (i).] The protective wrapping for a batch of articles, to be inserted in an outer shell or container, such as cigarettes, is formed in two parts, which overlap to form a substantially airtight wrapping, so that one of the parts may be completely removed, when desired, to expose one end of the articles. The wrapping, either with or without a lining sheet, may be formed round the batch of articles and the ends folded in, as shown in Figs. 1 and 3, it may comprise block-ended cups as shown in Fig. 6, or one wrapping may be folded in and the other comprise a block-ended cup as shown in Fig. 5. If the ends are folded in the upper wrapping is removed, when desired, by first lifting one of the folded edges to form a hand hold, as shown in Fig. 3. If blocked ended cups are used a tab such as 16, Fig. 6, is either affixed to the end of the cup or cut out of the wrapping to provide a hand hold for removing the wrapping ; whilst if the ends are folded in and secured by adhesive, a small portion at the extreme edge of the fold is left unsecured, as shown in Fig. 5, for this purpose.

Sheets are fed to rotary printing-machines by means of feed rollers 4, 5 intermittently driven from the printing-couple 1, 2 by means of a toothed sector 19 having a free-wheel connection with the roller 4. The invention is especially applicable to copying machines in which a mirror script hectographic impression is transferred to the printing-cylinder 1, and in which the sheets are moistened by means as described in Specification 608,785, [Group III]. The sector 19 is rocked by a reciprocating link 16 reciprocated by an oscillating lever 9 actuated by a cam 8 on the shaft of the printing-cylinder. The cam 8 engages a roller 10 on lever 9 to actuate the link 16 in one direction, and the return motion is effected by a fixed spring 11 or by the action of the cam on a roller 13 on the lever 9. The link 16 is fitted with a pin 17 adjustable in a radial slot 18 in the toothed sector 19 to vary the extent of movement of the roller 4. To adjust the pin 17 the link 16 is slotted at 25 and a pin 26 carried by an adjustable lever 27 raises or lowers the link when the lever 27 is adjusted angularly by nut-and-screw mechanism 32, 33, 34. A pointer 35 and scale 36 indicate the position of the lever 27 and the extent of oscillation of the sector 19. As an alternative adjusting arrangement, the pivot for the lever 9 may be mounted on an adjustable slide.

Title: Process and device for the electrical registration of the unbalance of revolving articles
IPC: G01M1/22

Abstract: 756,168. Measuring rotor unbalance electrically. AVERY, Ltd., W. & T., (Schenck Maschinenfabrik Ges., C.). Sept. 26, 1953, N.o. 26531/53. Class 40(1) The unbalance force of a rotor at each of two bearings is determined by a vibration pick-up feeding into one coil of each of two wattmeter movements supplied on the other coils with synchronous reference voltages 90 degrees apart, the resulting movements of the pointers of each of the wattmeters, which are proportional to the rectangular components of the unbalance force, being superposed on a common chart at right angles to each other, so that the crossover point establishes the magnitude and phase of the unbalance force at that bearing. As shown, Fig. 1, a rotor 3, supported in bearings 1, 2, is rotated by a motor 4, the unbalance force at each bearing being measured by vibration pick-ups 10, 11 respectively and fed as a voltage to a measuring instrument 17L, 17R respectively, each comprising two wattmeter type movements having one coil fed from the device 10 or 11, and the other coils fed with reference voltages with a 90 degree phase difference obtained from a generator 15 also driven by the motor 4. In one embodiment of the two wattmeter type instrument 17L, 17R, Fig. 3, each movement 32a, 32b has its own pointer 33a, 33b respectively crossing at 90 degrees at the centre of a calibrated chart 39 when the rotor is at rest, the position of the crossover point 38 during rotation indicating the phase and magnitude of the unbalance force at the appropriate bearing. The positions of the pointers 33a, 33b may also be noted on individual scales 36, 37 indicating the magnitudes of the individual components. In a further embodiment, Fig. 4, the pointers 73a, 73b are U-shaped, moving over a spherical chart 76 marked as for a polar co-ordinate system. The pointers may be fixed in their indicating positions by energizing an electromagnet 103 to attract a spring arm 102 attached to each pointer, the spring 102 carrying an auxiliary pointer 102a for indicating on a dial 101. The deflection of the spring arm 102 along a fixed contact track (not shown) may be used to produce a signal proportional to the unbalance force to control unbalance correcting machining operations as described in Specification 744,295. In a modification the wattimeter type movements rotate two mirrors whereby a light beam is deflected in accordance with the rotations, and indicates the resultant unbalance force by a light spot on the polar chart, or by two lines of light across the chart. Furthermore an image of the rotor may be projected on to the chart so that the position of the resultant unbalance force is visually indicated.
