Abstract: 767,987. Supply circuits for space discharge apparatus. CROMPTON PARKINSON, Ltd. June 23, 1955 [July 7, 1954], No. 19911/54. Class 38 (4). In a supply circuit for at least two electric discharge lamps 1, 15 each having two electrodes 2, 3 and 17, 18 requiring preheating before starting of the lamps, said lamps being connected in parallel with one another to a source of supply 9 each in series with a respective ballast 8 and 16, 23, one, 1, of the lamps has connected in parallel with it the primary winding 7 of a starting transformer 6 of which one secondary winding 4 is connected to heat only one electrode 2 of said lamp 1 whose other electrode 3 is heated before starting only by the discharge current of the other lamp 15 which latter has both its electrodes 17, 18 heated by further secondary windings 19, 20 of the transformer 6. Where three or more lamps are used the first of the group has both electrodes heated by the transformer, the last of the group is shunted by the transformer primary winding, while each lamp after the first has one electrode heated by the transformer and the other by the discharge current of the preceding lamp of the group. By these circuits parallel connected lamps may be started by a transformer in parallel with one of them without the risk of not all the lamps starting due to the transformer voltage falling when the lamp across which it is connected starts.

Patent GB-687554-A (GB)
Title: Improvements in or relating to transmission devices comprising an automatically operating overload-release clutch
IPC: F16D43/20
Filed: 1951-08-27
Abstract: 687,554. Overload release clutch. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 27, 1951 [Aug. 30, 1950], No. 20143/51. Class 80 (ii). A transmission device comprising an automatically operating overload-release clutch, the driven part of which, after complete disengagement subsequent to overload continues to be subjected to a driving force operating in the direction of movement followed prior to disengagement, is characterised in that the driving part and the driven part of the transmission device are coupled not only by the clutch but also by a one-way coupling which automatically arrests movement of the driven part of the transmission device relative to the driving part in the direction of movement for which the clutch is actuated when overload occurs. Journaled on stationary shaft 10 is a driving wheel 1, an auxiliary member 2 and a driven wheel 3. For normal running drive is taken from wheel 1 by an associated ratchet wheel 4 and thence to the auxiliary wheel 2 by a pawl 5; the auxiliary wheel 2 being connected to the driven member as by springs 6. In parallel with the clutch is a one way coupling assembly. Toothed wheel 12 meshing with the wheel 1 is free on a fixed sleeve 11. A member 14 is linked to the wheel 12 by means of a claw coupling 13 and is also free to rotate about sleeve 11. The member 14 is arranged within a toothed wheel 15 and the two are separated by rollers 16, together constituting a ratchet wheel coupling. The wheel 15 meshes with the driven wheel 3 of the clutch. The driven member 3 is thus prevented from exceeding the speed of the driving member 1 by the coupling rollers 16. If overload occurs the pawl 5 is disconnected from the ratchet wheel 4 by a controlling member such as a stud 7 on the member 3. The auxiliary member 2 is prevented from rotating backwards by ratchet gearing 8, 9. Should the overload be released suddenly the rollers 16 prevent the wheel 3 from moving faster than the wheel 1. A stud 18 in a sliding member 30 engages in an annular recess 17 in the wheel 12. To reset the member 3, a knob 24 on a spindle 22 is depressed, so that a gear 23 is engaged with a wheel 20, and the wheel 12 is disengaged from the wheel 14. Wheels 12, 14 are normally urged together by the spring 21.

Title: Error correction in digitally coded information
IPC: H03M13/00
Filed: 1974-05-08
Abstract: 1468604 Encoder/decoder HONEYWELL INFORMATION SYSTEMS Inc 8 May 1974 [29 May 1973] 20376/74 Heading G4A An encoder/decoder generates check bits in accordance with a reversible cyclic code, detects an error syndrome and develops an error pattern after reversing the order of the syndrome bits. (A reversible cyclic code is one in which for each and every code word the word resulting from reversing the order of the bits is also a code word). In the embodiment of Fig. 2A for implementing the (35; 24) Fire code using the generator polynomial P(X)=1+X+ X<SP>2</SP>+X<SP>3</SP>+X<SP>4</SP>+X<SP>7</SP>+X<SP>8</SP>+X<SP>9</SP>+X<SP>10</SP>+X<SP>11</SP>, to correct burst errors of up to 4 bits, after 24 information bits have been sent to feedback register 10 the register holds 11 check bits which are added to the information bits. Decoding is effected by sequentially feeding all 35 bits to the register and if the information is correct at the end of this operation upper and lower zero detectors 31, 32 will receive zeros from stages R 7 -R 10  and R 0 -R 6  of the register 10. If any of the bits were incorrect the register will instead hold a syndrome which is reversed, using gating 11, 15, the register then being cycled as before until the first six positions are all zero (detected by detector 31). The contents of the last four stages then represent the error pattern and the number of cycles of the shift register indicate the most significant bit in error in the received word held in buffer register 20. In the embodiment of Fig. 6 (not shown) polynomial register 69 contains the ten least significant terms of the polynomial (Px) and is connected via a switch (71), exclusive-OR gates (67) and switch (65) to syndrome register (66) which is selected to step right during encoding and decoding and left for error computation. Use of a reversible cyclic code permits any length of code word up to a predetermined maximum to be corrected more quickly than using a normal cyclic code since cycles are not utilized for processing high order zeros.
