Title: Electric motor speed control systems
Inventor: PEPPER EDWARD JOHN
IPC: H02P25/28
Filed: 1962-01-11
Abstract: 1,027,332. Automatic speed control. ENGLISH ELECTRIC CO. Jan. 11,1963 [Jan. 11, 1962], No. 44800/61. Heading G3R. [Also in Division H2] In a system for controlling the speed of a squirrel cage induction motor 10, e.g. for a knitting machine, by comparison of a reference signal adjustable in steps with an actual-speed signal, braking torque is temporarily applied when a reduction of the reference signal is made, to slow the motor to a speed slightly above that corresponding to the new signal. The actual-speed signal, rectified from A.C.tachogenarator 26, appears as a voltage across resistor 28 in opposition to the reference voltage from tapped potentiometer 19, and the result controls a transistor amplifier 15 supplying D.C. control winding 14 of a saturable reactor 13 in the supply circuit of the motor. The control winding is shunted by an energy dissipating circuit comprising resistor 31, diode 32 and Zener diode 33. A braking winding 34 is energized with D.C.from a second transistor amplifier 35 when signalled by either of two monostable transistor devices 37, 38. These produce a steady positive output until a short input pulse is received; the output voltage then drops for a finite time, predetermined by the time constant of an RC circuit. Such a a pulse is applied to device 37 upon a drop in reference voltage, and thus the brake winding is energized for a preset time. Upon the output of 37 regaining its original value, which cuts off brake amplifier 35, an input pulse is applied to a third monostable device 42 which, after an interval, triggers the device 38 which causes braking to be effected again for a short time. The time constants are arranged to bring the motor to its new speed with a minimum of hunting and are adjusted by switches, not shown, ganged to speed control switches 23...25 and stop switch 22 to match them to the particular speed change effected. The secondary monostable devices 38, 42, may be omitted. During braking the amplifier 15 is positively cut off by a signal through capacitor 45 to reduce the motor input to a minimum.

Title: Method and apparatus for providing solid reproductions
IPC: H04N1/50
Filed: 1963-11-14
Abstract: 1,001,433. Copying by scanning. L. G. SINJIAN. Feb. 19, 1964 [Nov. 14, 1963], No. 45026/63. Heading H4F. Apparatus for providing a coloured mosaic on a base sheet 18 of a colour subject 12, e.g. print or painting, comprises scanning means 26 which scans the colour subject along a predetermined pattern, e.g. by means of X-Y drive step motors 36 and 38, and a corresponding reproducing means 28 which moves uncomitantly with scanning means 26 and includes storage and dispensing means, Figs. 3 and 4, for storing and dispensing solid preshaped particles of round, cube or rectangular prism shape and made of plastics or a substance similar to marble. Control means 50 provides motion of the scanning and reproducing means in lineby-line fashion with the line spacing equal to the particle size and also a periodic pulse signal to relay 52 which governs the deposit of particles. Subject 12, Fig. 2, is scanned pointby - point by a plurality of photo-electric sensing means 62, 64, 66 each having an associated optical filter 68, 70, 72 responsive to a particular colour. If filter 68 is red a colour responsive signal denoting red is received by inhibitor circuit 76 and amplifier 78 and transmitted via switch contact 80 of relay 52 to solenoid 82 which forms part of the reproducing means 28 to cause dispensing of a red coloured three-dimensional particle or to base sheet 18. White colour is sensed by signals at each of the sensing means 62, 64, 66, which signals pass via an AND circuit 86 to a white coloured particle dispensing solenoid 92. Black colour is sensed in the absence of signals by a NOR circuit 94 which is connected to a black coloured dispensing solenoid 100. Figs. 3 and 4 show the dispensing means in which solid preshaped particles 102 associated with a certain colour are contained in respective vertical tubes 104 at the lower ends of which are solenoids such a 92 and 100 which have movable brackets 110 having holes through which a particle falls when relay 52 is activated i.e. bracket 110 advances towards the centre of the funnelshaped exit portion 112, the released particle attaching itself to adhesive layer 105 on base sheet 18. The finished mosaic when made of plastic parts may be baked and cured or cemented to the base surface. The subject and base sheet may move relative to the scanning and reproducing means to obtain the predetermined pattern or the subject and base sheet may be mounted on cylindrical surfaces and if the particles are small a helical pattern may be traced. In a further embodiment (Fig. 6, not shown) the colour responsive signals generated by the scanning means are fed to a translating means which transforms the signals to proper form for recording and storage means, e.g. magnetic recording means or punched tape, and for reproduction the recorded data is played back to read-out means.

Title: Bonus crediting system
IPC: G07F9/00
Filed: 1969-09-12
Abstract: 1,254,509. Bonus crediting. SEEBURG CORP. OF DELAWARE. 12 Sept., 1969 [12 Sept., 1968], No. 45051/69. Headings G4A, G4D and G4V. A vending apparatus including a credit accumulator having a bonus crediting arrangement comprising a circuit for accumulating and storing electrical pulses representing credit substantially simultaneously with accumulation and storing in the credit accumulator; crediting means for providing a bonus credit signal when a certain number of credits have been accumulated and reset means for returning the memory to its initial state after the bonus credit has been provided. This is for use with a crediting accumulating arrangement for a coin operated vending machine as described in Specification 1,254,510. Single credit pulses appearing on line 11, double pulses on line 13, and quintuple pulses on line 15, feed a chain of four bi-stables 17, 19, 21, 23 and, by means of the numerous gates shown cause one bonus credit signal to be sent down line 71 for every five credits received and then return the flip-flops to their initial state. If ten credits are received, four bonus credit signals are sent down line 101. The entire circuit is reset on initiation of a vending operation or a new credit sequence. A clock circuit ensures that the bonus credit issued does not coincide with a credit increment and the arrangement may be formed as an integrated circuit.

Title: Read/write circuits for digital recording
IPC: G11B20/10
Filed: 1974-10-18
Abstract: 1484317 Digital storage systems RCA CORPORATION 18 Oct 1974 [25 Oct 1973] 45193/74 Heading G4C Each bit of serial digital signal is recorded as a group of several pulses, the number of pulses in a group being indicative of the bit state, and each being separated from the next by an interbit gap in which no pulse is recorded. The circuit shown in Fig. 3 is a combined Read and Write circuit. In the Write mode a controller, not shown, applies a signal WR. The bit to be recorded is applied at terminal Data In and in the case of a 1-bit, sets bi-stable 307. Pulses from oscillator 301 pass via AND gate 309 to counter 311 and to the write head via gate 326. When counter 311 reaches 5 AND gate 315 triggers monostable 303. The astable period of the monostable is equal to the interbit gap. During this period gate 305 is inhibited and so, bi-stable 302 being in its reset state, gate 309 is also inhibited, preventing pulses from reaching the write head and the counter. The 0 output of OR gate 320 triggers monostable 304 which resets counter 311 (and also a counter 310) and provides a Data Request signal to the controller which thereupon issues a signal SVC to reset bi-stable 307 and issues the next bit to be written. If the bit to be recorded is a 0-bit bistable 307 is not set and AND gate 317 triggers monostable 303 after two pulses have been written, the operation otherwise being identical. In the Read mode the controller applies a signal RD. Pulses from the read head are counted by counter 310 and set bi-stable 302. Bistable 307 assumes the state of the last stage of counter 310. Bi-stable 302 enables gate 309 to pass pulses from oscillator 301 to counter 311. By the time counter 311 has reached 5 the read head will have reached the interbit gap and counter 310 will contain a count of 5 in the case of a 1-bit or 2 in the case of a 0-bit. When counter 311 reaches 5 AND gate 325 resets bistable 302 which prevents further oscillator pulses from reaching counter 311, causes monostable 304 to reset counters 310, 311, and provides a Data Ready signal to the controller to indicate that the state of bi-stable 307 corresponds to the state of the bit just read. When the counter has accepted the bit on Data Out it sends SVC to reset bi-stable 307. If only 4 pulses are read a 1-bit will still be indicated because the last stage of counter 310 will have been set to 1. Separate write and read circuits are described (Figs. 1 and 2, not shown). These circuits operate in a similar manner to that described above, but the read circuit employs a shift register (210) rather than counter 310.

Recording and playback apparatus comprises a rotatable mounting plate provided on one side with a plurality of spiral formations, a recording disc mounted so as to be rotatable about the axis of rotation of the mounting plate, and a transducing head assembly and driving means therefor including a follower engageable with one of the formations so as to move the head assembly over the disc in conformity with movement of the follower as the mounting plate rotates. In Fig. 1, a magnetizable record disc 1 is attached to the upper surface of a mounting plate 2 secured to a rotatable shaft 3. A transducing head 12 including one or more transducers is carried by one end of a U-shaped link arm 11, the other end of which carries a follower 10 which engages one of the spiral grooves 9a, 9b or 9c, formed in the lower surface of mounting plate 2. A pair of fixed guides 14 (only one of which is shown in Fig. 1), constrain the transducing head and follower to move in a radial direction. The follower is pivotally mounted on the link arm 11, and when it reaches the innermost end of the groove 9 it is lifted out of engagement by an inclined plate (not shown) so that the follower and head can be returned to an initial position, e.g. by a spring. In an alternative mounting arrangement, Figs. 3 and 4 (not shown), the head and the follower are mounted on arms attached to a spindle which pivots about a vertical axis. The spiral grooves in the mounting plate may be engageable by a single follower or by a particular one or any of a plurality of followers, each associated with a head assembly. As an aid to selecting a particular groove the shaft 3 may be provided with cams adapted to close electrical contacts at particular angles of rotation. One or more additional recording discs may be mounted on the shaft 3 and scanned on both sides by transducer heads coupled to the same mounting used for the head 12, Fig. 12 (not shown). In another arrangement, Fig. 13, the recording disc 1 is mounted separately from the mounting plate 2; the disc and the plate may rotate at the same or at different speeds. This arrangement is suitable for optical methods of reading, as a light source movable with the follower 10 may be mounted adjacent the side of the disc 1 opposite to that over which the head assembly moves.
