Patent GB-1072535-A (GB)
Title: An electrical speed control apparatus
IPC: B65H23/188
Filed: 1965-11-02
Abstract: 1,072,535. Feeding webs. MIEHLE-GOSS-DEXTER Inc. Nov. 2, 1965 [Nov. 6, 1964], No. 46420/65. Heading B6B. [Also in Division G3] The peripheral speed of a new roll of web material is matched with the linear velocity of a running web so that the webs may be spliced without being severed. Closure of switch ES1 provides signals to gates AND 2, AND 4, and energizes motor 15 which is adapted to drive the new roll. Gear 12, which is driven by the expiring roll, is associated with pick-up 11 whereby a first pulse derived from monostable circuit FF1 sets bi-stable circuit FF3 to condition gate AND 1 for the passage of a pulse. The next pulse from the circuit FF1 is transmitted through the gate to set the bi-stable circuit FF4, clutch 17 being energized to couple the motor 15 to the new roll which is associated with gear 14, pick-up 13, and monostable circuit FF2. As long as consecutive pulses from the circuit FF1 occur between consecutive pulses from the circuit FF2, indicating that the gear 12 has a greater speed than the gear 14, the motor 15 remains in driving engagement with the new roll which is accelerated. When the speed of the new roll exceeds that of the running web, the circuit FF3 is driven to the reset condition, gate AND 3 is conditioned for the passage of a pulse, and circuit FF4 is reset to energize brake 18, the clutch 17 being de-energized. Thus, the clutch and brake are alternately energized to synchronize the speeds of the new roll and running web.

Title: Data handling apparatus
IPC: G06K7/00
Filed: 1973-10-10
Abstract: 1440106 Data encoding INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1973 [26 Dec 1972] 47196/73 Heading G4C In a data encoding arrangement, each data bit is represented by an NRZI bit pair derived by examination of at least the two adjacent data bits as well as the data bit to be encoded. The coding may be such that no two adjacent NRZI bits are 1s and not more than three consecutive NRZI bits are 0s. Thus, a "0" data bit is encoded as a bit pair 10 if the preceding data bit is also "0" or if the preceding data bit is a "1" encoded as 00, otherwise a "0" bit is encoded as 00. A "1" bit may be encoded as 00, 10 or 01. A bit pair 01 cannot be followed by 10 but must be followed by 01 if the next data bit is also a "1". A "1" data bit encoded as 00 is always followed by 10 irrespective of whether the next data bit is "1" or "0". In Fig. 2 a bit to be encoded is designated do and bits preceding and following that bit are assigned negative and positive suffixes. The values of the NRZI bit pair a 0 , b 0  are dependent not only on the value of the bit do but also on the value of the preceding bit d 1  and the bit pair a 1 , b 1  with which that bit was encoded, on whether the number of 0 data bits in the sequence preceding and ineluding do is even or odd (PB), and on whether d 0 , if a 1, is followed by an even or odd number of consecutive is before the next 0 (PA). The circuit shown implements the a 0 , b 0  functions given at the bottom of the Figure. The decoder Fig. 3 (not shown) includes a shift register for storing a -1 , b -1 , a 0 , b 0  and a 1 , b 1  and gates for obtaining each data bit do from the equation d 0 =b 0  + a 0 a 1 b 1  + a 0 a -1 b -1  so that d 0 = 1 if a 0 b 0  = 01 or if a 0 b 0  = 00 and a -1 b -1  =10 or if a 0 b 0 =10 and a 1 b 1 =00. The decoder may also include a pair of bi-stables for obtaining the parity PB of decoded "0" bits up to and including d 0 , and PB 1 representing the number of "1" bits since the last 0 bit. The signals PB, PB1 may be used together with the NRZI pairs to indicate an error if two adjacent "1s" or four adjacent "0s" appear in the NRZI pairs or if 10 is followed by 00 when PB = 0, or if, with PB = 1 and PB1 = 0, the next NRZI pair is 00.

Abstract: 1,131,936. Counters. E. E. J. UNDERBERG, and S. A. DOLD. 10 Nov., 1965 [11 Nov., 1964], No. 47692/65. Heading G4D. [Also in Division H2] In a dynamo-electric machine having a stator and a movable member, the stator (in the example shown) has an auxiliary pole 6 connected to a " main " pole 5, the other " main " pole 4 being connected to the " main " pole 5 only. The movable member 2, which is a permanent magnet, thus has a preferred direction of rotation (clockwise in the example shown) (see Division H2). For use as a single-step counter, the stator winding 7 is connected to a source of D.C. with the interposition of a relay, or switches with double reversing contacts, for producing pulses of alternating direction, the relay being energized in synchronism with the articles to be counted. For example, bottles may be conveyed through a light beam causing the operation of a photo-electric cell acting on the relay. The machine may be provided with a further pair of poles together with the associated auxiliary pole, arranged in opposite fashion to the first set of poles, so that positive and negative elements may be fed to the machine, and the machine operates as an integrating counter for forming a total from the positive and negative elements. For example, signals of a weather detector may be converted into control instructions for an electric heating installation. Another example is in programme control of a washing machine for automatic repetition of operations. A linear embodiment is described (Fig. 9, not shown).

Abstract: 1331947 Automatic steering control ANSCHUTZ & CO GmbH 7 Oct 1970 [14 Oct 1969] 47774/70 Heading G3R A radio navigation receiver 1 on a ship 7 produces an output signal corresponding to the phase-angle between transmissions received from two different radio stations which is compared in a controller 2 with a signal corresponding to a desired phase angle set by a knob 123 so that any error is applied to adjust the datum of heading controller 3 and thus maintain the ship on a chosen hyperbolic radio course. Heading controller 3 compares a signal from a gyro 8, responsive to the ships' heading, with a signal corresponding to a manually set heading corrected by the error signal from controller 2. Any error signal from controller 3 is applied to a controller 4 adjusting the ships rudder 6 to correct the course, follow-up signals from a transducer 5 being fed back to controller 3. Controller 2 includes a transistorized detector, responsive to fall in positioning signals which occurs deliberately and periodically while approximate but unambiguous signals are transmitted which ensures that capacitively stored values of the last accurate signals are utilized for control until accurate signals are restored. Controller 2 also includes an error indicator, recorder and alarm, a switch which is operated to suit the direction of travel and a resistance-capacity PID network the sensitivity of which is manually adjustable. On first switching on, the heading error signal is fed back from controller 3 to controller 2 through AND gates to discharge the integrations feedback capacity. Suitable phase comparison networks including resolvers or potentiometers are described and digital computation is referred to.
