Patent GB-1016559-A (GB)
Title: A pulse counting system
IPC: G01R23/10
Filed: 1964-09-21
Abstract: 1,016,559. Electric selective signalling. MINNESOTA MINING & MANUFACTURING CO. Sept. 21, 1964 [Sept. 24, 1963], No. 38460/64. Heading G4H. A transducer 14 in a pipeline delivers a pulse for every <SP>1</SP>/ 1000  barrel of liquid passing. The pulses are fed to a series of decimal counters 20, 22, 24, 64, the total number of barrels being registered on an electro-mechanical counter 40. After the delivery of each ten barrels a pulse on lead 66 starts a time base 80 for 3À6 seconds, at the end of which a pulse on lead 36 transfers the reading on counters 20, 22, 24, 64 to Nixie tubes 56 which therefore indicate the rate of flow in barrels per hour. This indication persists until the completion of the next measuring period. The operation of counters 44, 46, 48, 50 associated with the Nixie tubes may be checked by inserting a " rubber pig " in the pipe line to open and close a gate 78 as it passes transducers 86, 88.

Title: Synchronisation of cinematographic film with another information carrier
IPC: G03B31/04
Filed: 1974-09-04
Abstract: 1481435 Synchronizing sound strip and film-strip BOLEX INTERNATIONAL SA 4 Sept 1974 [6 Sept 1973] 38597/74 Heading G2E In a method of synchronizing a cinematographic film-strip 1 with another information carrier such as a magnetic tape 10 carrying corresponding sound tracks, the film-strip carries code markings 4 at the beginning of each sequence and the tape has code markings corresponding to each film frame, the two sets of code markings being decoded into two signals, the first signal controlling the projection speed and the second signal controlling the synchronization. The signals coincide at the start of a sequence, and a frame counter is set back to zero at the beginning of each sequence by a signal transmitted by a device (26), Fig. 2 (not shown), which reads the markings on the film. A reading head (28) transmits current to two frequency filters (30, 31) which separates the controlling signals from the synchronizing signals. Each control signal produces an impulse which is transmitted to the film feed claw which moves the film forward one frame. The synchronization signal is transformed into an impulse which is received by a coincidence stage (27). If, for any reason, an impulse is "lost", the tape and the film are out of phase, and the film is one frame behind the tape. In such case, the coincidence stage (27) transmits a signal to an impulse generator which in turn is transmitted to the feed claw, so causing the film to move forward one frame. Thus the film and tape are again in synchronism.

Abstract: Iron oxide pigments containing manganese in solid solution and having a uniform haematite structure are prepared by a process of oxidizing metallic iron with an aromatic nitro compound in the presence of manganese metal or a manganese compound (see Division C1), black pigments being produced when the weight ratio of Fe: Mn is from 14: 1 to 5: 1 and reddish brown to brown pigments when the ratio is from 100: 1 to 15: 1.ALSO:Iron oxide pigments containing manganese and having a uniform haematite structure are produced by oxidizing metallic iron with an aromatic nitro compound at a pH of 3.5 to 6.5 in the presence of manganese metal or a manganese compound and an aqueous ferrous salt solution, and/or a concentrated aqueous solution of a salt which can be hydrolysed or an aqueous suspension of a difficultly water soluble oxide, hydroxide, or basic salt of a trivalent or tetravalent metal, or phosphoric acid, or a dissolved or suspended lead compound, or iron oxide or hydroxide nuclei obtained from yellow, reddish brown or red iron hydroxides or oxides, and working up the resulting pigment sludge by filtering, washing and calcining at 600 DEG  to 800 DEG  C.  The pigments produced consist of a solid solution of alpha-Mn2O3 and alpha-Fe2O3.  Reddish brown to brown pigments are formed if the weight ratio of iron to manganese is from 100:1 to 15:1 and black pigments when the ratio is from 14:1 to 5:1. Specified manganese sources are manganese alloys, MnCl2, MnSO4, Mn(OCOCH3)2, pyrolusite and rhodochrosite.

Abstract: 1,199,200. Protective arrangement. COMPAGNIE DES COMPTEURS. 6 Sept., 1967 [12 Sept., 1966], No. 40661/67. Heading H2K. A distance protective arrangement for a threephase system with an earthed neutral, comprises for each phase a series circuit consisting of the secondary winding of a transformer 21, 22 or 23 having a primary winding connecting the phase to earth, a replica impedance 14, 15 or 16 supplied by a current proportional to the phase current, and a replica impedance 17 supplied by the zero sequence current. These circuits are connected to amplifiers 1 . . . 3 which convert their input voltages to two-state logic output signals. These output signals are applied to an AND circuit 4 and a NOR circuit 5 and the output signals of these circuits are applied to an OR circuit 6 which is connected to a temporary storage circuit 7. This circuit 7 is connected to a tripping device (not shown). When a fault to earth occurs within the protected zone, the three voltages applied to the amplifiers 1, 2, 3 are simultaneously positive or negative during parts of a cycle. When the voltages are simultaneously positive the AND circuit produces a signal and when the voltages simultaneously negative the NOR circuit produces a signal. These signals are of short duration, but are converted by the circuit 7 into a steady tripping signal. A delay circuit may be provided between the circuits 6 and 7.

Abstract: 953,804. Projection systems. SAUNIER DUVAL. Nov. 30, 1960 [Dec. 1, 1959], No. 41201/60. Heading G2J. For displaying information by projection at one or more positions remote from an operating position, a card bearing the information is dispatched, by pneumatic means, from a control desk at the operating position to a projector along a tube system, means being provided at the operating position for electrically controlling pneumatic values whereby the card may subsequently be rejected, or passed to a further projection system. As shown in Fig. 1 the card 37 is formed with a vane 38 by means of which it is driven along rectangularsection tubes (Fig. 6) by compressed air. The flow of air in the tube system is controlled by a solenoid-operated pneumatic valve 3 in the blower which is actuated whenever a duplicate pilot card of the one to be projected is inserted into one of a plurality of compartments provided in the control desk. Insertion of the pilot card, after the one to be projected has been inserted via a slot 19 into the tube system, triggers switches which , in dependence upon the particular compartment selected, will operate a corresponding one of a series of valves 22 to guide the card to a predetermined branch of the tube system, and at the same time will operate valve 3. When a card 37 (see Fig. 5) arrives at the selected projection position it is trapped by a solenoid-operated comb 56 between transparent portions of the tube aligned with a projection system. The lamp 54 of the latter is energized and at the same time valve 3 is closed, by means of a limit switch 24 actuated by the arrival of the card. The card may then be rejected, by means of a deflecting flap, in response to a signal from the control desk given by removing the pilot card from its slot. Otherwise the card will proceed automatically to the next projector along the line.
