Patent GB-172690-A (GB)
Title: Improvements in or relating to machines for measuring, gauging, or the like
IPC: G01B5/252
Filed: 1920-08-12
Abstract: 172,690. Wickman, A. E. Aug. 12, 1920. Surface and outline gauges.-In an apparatus for gauging gear wheels &c., the wheel is clamped ori a rotary mandrel 4 and its teeth are felt in succession by a spherical-ended contact-member 1 connected with a dial-gauge 5. The member 1 is secured to a blade spring mounting 2, an extension of which bears against the plunger 6 of the dial gauge. Also attached to the mounting is one end of a lever 19 pivoted at 20 and provided at its other ends with a damping-vane 22 immersed in viscous liquid. Parallel with this lever is a second similarly-damped multiplying lever connected with it by a pointed strut 26 and a pair of tension springs attached to stirrups 28 pivotally bearing on the levers. One end of the second lever is formed as a pointer to show on a scale and lateral displacement of the contact-member. The contact-member is readilv removable for replacement by one of different shape, and during such operation the lever 19 may be held stationary by a plunger 50 raised to engage a hole 49 by manipulation of a lever 51. The above-mentioned parts are mounted on a sliding frame moved by a rack and pinion so as to adjust the position of the contact-member with respect to the work. The mandrel is rotated by means of a worm and worm-wheel 33. The worm is carried by a shaft 34 turned by means of a micrometer head 35 with removable scale, and is adjustable laterally to take up wear by the provision of inclined surfaces between its supporting frame 41 and the base on which this frame is slidably movable. To carry out a test, the wheel is clamped on the mandrel and the parts adjusted so that the contact-member bears evenly between and against neighbouring teeth, this being shown by a zero reading of the multiplying lever. The dial gauge is now read and the mandrel is rotated to bring the next tooth space into position to be felt, the correctness of such position being indicated again by a nil reading of the lever. Any variation in radius of the pitch circle will now be indicated by the dial gauge, and the pitch will also be given by the micrometer head 35. In a modification, Fig. 7, adapted for testing bevel and helical gears, the mandrel 4 can be tilted by being slid along an arcuate-graduated arm 52 which is revoluble about a vertical pivot 56. The mandrel and its supporting parts are carried by a frame member 58 vertically adjustable on the frame 59.

Abstract: 1,140,715. Curve-describing appliances. J. JACONELLI. 26 May, 1967 [26 May, 1966], No. 23688/66. Heading B6P. An appliance for drawing curved lines to produce a design, comprises a rotatable table 5 carrying the sheet of paper on which the design is to be drawn, and a marking stylus 10 which is reciprocated rectilinearly in a direction perpendicular to the axis of rotation of the table 5. The table 5, Fig. 1, is carried by a shaft 6 journalled in frame members 2, 3 and is rotated by worm gearing 19, 21 connected to a shaft 17 rotated by a handle 18. A platform 8 slotted at 9, Fig. 2, to receive the shaft 6 and slidably mounted on rods 7, has a loop-shaped connecting-rod 29 pivoted thereto at 31, the other end of the rod 29 being adjustably connected to a crank-member 27 rotated from the shaft 17 through gearing 20, 22, 23, 25 to reciprocate the platform 8. A vertical flange 11 on the platform 8 carries a horizontally-adjustable rod 14 to which is pivoted an arm 13 along which a holder 12 for the stylus 10 can be adjustably secured. By varying the initial setting of the stylus different curves may be drawn. A ball-point pen may be used as the stylus, and pens with differently-coloured inks may be employed to produce designs having curves of differing colours. In place of the worm gearing 19, 21, an arm pivoted about the spindle of gear 21 may carry replaceable gear trains which by movement of the arm can be brought into engagement with a gear on the shaft 17.
Patent GB-960843-A (GB)
Title: Improvements in code transmission methods
IPC: H04L25/49
Filed: 1961-06-30
Abstract: 960,843. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. June 30,1961 [July 1, 1960], No. 23739/61. Addition to 892, 552. Heading G4H. The equipment comprises means for transmitting a constant duty-ratio code, the "ones" and "zeros" being represented as disclosed in the parent Specification. A change in polarity occurs at the beginning of each signal time and constitutes a synchronizing element of a code signal, a further change in polarity half way through the signal time represents a "one", and no further change represents a "zero". A code comprising three characters each of which is made up of five code signals arranged in a two-out-of-five code is generated by means of switches CH-C15, C21-C25, C31-C35 and distributer counters MS1, MS2, Fig. 1a, and applied to the base of transistor gate tr 7, Fig. 2 so that clock pulses occurring on lead f1 in the middle of each signal time are suppressed when the simultaneously occurring code signal is a "zero". The "1" output of bistable circuit B1 is shown in Fig. 3 for the sequence of fifteen code signals 1, 0, 0.... 1. At the start of the sixteenth signal time, gate tr 8 suppresses the pulse on lead f2, and the pulse which follows on lead f1 is also suppressed by gate tr 7 so that a code synchronizing signal is obtained in which no changes of polarity occur over the signal time. At the receiver, a bistable circuit B2, Fig. 1a follows the changes in line polarity, a monostable circuit N1, Fig. 1, having a relaxation time of over half the signal time is triggered at the start of each signal time and bistable circuit B3 is set to the same state as B2 at the start of each signal time. If a further change in polarity occurs, signifying a "one", B2 changes state again but B3 remains unchanged. Bistable circuit B4 is set to the appropriate state by each code signal. Counter distributers MS1, MS2 receive pulses from N1 and supply the outputs of B4 to the appropriate storage capacitors cd 3 which are only partially charged in a signal time if the code signal is a "one". When the code has been repeated and received correctly a predetermined number of times, the appropriate transistors tr 9 conduct and the associated storage relays rm are operated. The code synchronizing signal is detected by means of circuits N1 and N2, the latter being triggered on when N1 restores to normal and having a relaxation time chosen so that it does not restore to normal until after the start of the next signal time. Diodes di 9 and di 10 are thus both blocked in the sixteenth signal time and counters MS1 and MS2 are driven to the correct states if these are not already existing.

Patent GB-790383-A (GB)
Title: Improvements in tuner devices for radio frequency amplifier apparatus
IPC: H03J3/00
Filed: 1955-08-18
Abstract: 790,383. Inductors; automatic frequency control. GENERAL MOTORS CORPORATION. Aug. 18, 1955 [Sept. 7, 1954], No. 23818/55. Classes 38 (2) and 38(4). [Also in Group XL (c)] The tuning of a radio receiver repeatedly scans a wave band until a signal is tuned in, when the tuning is arrested and maintained by an automatic tuning correction system at the desired point. The tuning coils 42, 78, 82 for the amplifier and frequency changer stages of the receiver have ferromagnetic cores upon which are wound magnetizing windings 60, 62, 64 connected in the anode circuits of a parallel connected twin triode valve 130. The grids of this valve are connected to a capacitor 222 which slowly discharges from a negative ,.value causing the current in the valve to rise and thus the tuning to scan the wave range. The output of the receiver is fed through a limiter valve 156 to a discriminator circuit 174, 158 and the output from the discriminator is fed through a lead 202 to the grids of the valve 130. When a signal is tuned in the voltage from the discriminator is sufficient to stop the capacitor 222 discharging and thereafter the voltage also corrects any deviation of tuning. To re-start tuning a switch 252 is momentarily operated to earth contact 250. This causes a pulse to be transmitted through capacitor 246 to discharge capacitor 222 sufficiently to alter the tuning to a point outside the range of the discriminator so that the capacitor 222 continues to discharge until the next station is reached. Succeeding stations may be passed over by operating a switch 284 which disables the discriminator by earthing its output. The voltage across capacitor 222 is also fed to the grid of a valve 230 and when the tuning reaches the end of the band the voltage is sufficiently low to render valve 230 conductive. Accordingly a capacitor 226 rapidly discharges into capacitor 222 restoring the tuning to the beginning of the band. The negative voltage now present across capacitor 222 causes valve 230 to be cut off and the capacitor 226 rapidly re-charges but the pulse developed across resistor 232 is prevented from reaching capacitor 222-by a rectifier 224. Rapid return to the beginning of the tuning range may be effected at any time by operating a switch 270 which earths the left plate of capacitor 226 causing the latter to discharge into capacitor 222. The tuning inductances (Figs. 3 and 4) consist of two coils 42 wound respectively on reduced portions of two ferrite rings 54, 56 which are subsequently secured together and wound with a magnetizing winding 60 and overwound with a polarizing winding 290 through which a current is passed to offset the residual magnetism of the cores.
