Title: Improvements in or relating to the production of composite metal strip suitable for the manufacture of bearings
IPC: B23K20/233
Filed: 1961-10-24
Abstract: 940,924. Making composite metal strip for bearings. REPCO Ltd. Oct. 24, 1961 [Nov. 7, 1960], No. 38062/61.Heading B3A. A method of making a composite metal strip comprises, roll bonding a strip of aluminium-tin alloy to a strip of tin-free or substantially tinfree aluminium or aluminium alloy by a reduction in thickness during the first pass and roll bonding the tin free face of the duplex strip formed to a steel strip by a reduction in the first pass, each bonding face being suitably prepared prior to rolling, all bonding operations being carried out at ambient temperatures. In an example an aluminium ingot, 30% tin, 0.7 copper, remainder aluminium, is machined flat, rolled to a thickness of 0.3 inch and roll bonded to a 0.06 inch thick strip of pure aluminium by reducing it to 0.16 inch in a single pass. The composite sheet is further rolled to 0.04 inch and roll bonded to a steel strip by reducing it to 0.07 inch in a single pass. All the bonding faces are scratch brushed and the final strip annealed at 350 C. for half an hour. To avoid loss of tin by sweating during intermediate annealing an additional layer of tin-free aluminium may be bonded to the face of the aluminium tin strip. The steel strip may have multi-layer aluminium strips bonded on both sides. The composite strip may be used for shell bearings or bushes. Specifications 706,149, 749,529, 762,817 and 798,360 are referred to.

Abstract: 1399687 Regulating I C engines; ignition systems ROBERT BOSCH GmbH 16 Aug 1973 [17 Aug 1972] 38712/73 Heading G1N [Also in Division F1] A capacitor-discharge ignition-circuit includes a speed limiting section responsive to the rate of ignition pulses to temporarily disable the capacitor charging circuit. TIMING PULSE. The pulse from contactbreaker 36 is differentiated at 41, 47 and amplified by transistor pair 44, 57 having an output point 61 This pulse at point 61 is applied via line 7 to the rate circuit; diode 94 to the charging circuit; and firing control circuit 62, 72. The time constant of the differentiating circuit supresses pulses due to contact bounce. IGNITION CIRCUIT. The pulse from the firing control circuit 62., 72 is applied to the gate of thyristor 68 to discharge the ignition capacitor 70 through the coil 77.  CHARGING CIRCUIT, comprises a transistor 26 with a feedback transformer 86, and an output pulse-transformer 81. When stimulated by a timing pulse through diode 94 transistor 26 conducts until the feedback voltage across transformer 86 causes thyristor 28 to break down, cutting off transistor 26 so that inductive pulse is produced in transformer 81 to charge the ignition capacitor 20 through diode 23. An overspeed signal from the rate circuit will appear on line 101 to bias thyristor to a conducting state so that charging pulses are not generated. SPEED/RATE CIRCUIT. The timing pulses on line 7 are applied to an integrator capacitor (3) with pre-set leak resistors (13, 14) Fig. 1 (not shown). The voltage across the capacitor is applied to an amplitude sensitive switch comprising a transistor 110, Fig. 4, which controls the firing of thyristor 107 to apply a disabling signal on line 101 to the charging circuit.

Abstract: 1,133,879. Magnetic recording apparatus. SCIENTIFIC DATA SYSTEMS Inc. 31 Aug., 1966, No. 38904/66. Heading G5R. A control system for a magnetic tape-recorder adapted to record blocks of data from a data source comprises a magnetic tape 10 advanced past read-write heads 121, 122 by means of a capstan 11, the passage of fixed increments of tape past a stationary point producing control pulses which are passed to gates 28, 29 governing the passage of digital bits to write heads 121, the gap between the recording of two data blocks being metered by a counter 45. Magnetic tape 10 is slippage free coupled to a capstan 11 which is driven by a tachometer controlled motor 15 having a disc 25 supported on its shaft 16. Disc 25 is provided with tracks 25<SP>1</SP>, 251<SP>1</SP> having magnetically stored markers monitored by transducers 26, 27 which produce electrical sinusoidal signals during rotation of disc 25, the phase and frequency of each wave train being an exact indication of position and speed of the tape. The sinusoidal waves are respectively passed to gates 28, 29 which govern the passage of digital bits to write heads 121 through an " OR " gate 34, the output pulses of which serve as write clock pulses, and an " AND " circuit 35 which receives a write command signal from the set side output of a flip-flop 36. Gated pulses appearing at the output side of " AND " circuit 35 are passed to seven " AND " gates 37 as enabling signals, the writing of seven bits in parallel on tape 10 being clocked from pulses derived from disc 25. An end-of-record code is written after each record to actuate a detector 47 which turns off flip-flop 36 to block gate 35. When tape 10 has travelled a distance X, which is the distance between the read and write head gaps, a detector 41 connected to read head 122 is actuated to set a flip-flop 42 to open gate 43. This gate is connected to counter 45 which counts a predetermined number of bits before producting a write signal in line 46. Counter 45 thus meters the gap between records.

Abstract: 843,342. Furnaces. PRVNI BRNENSKA STROJIRNA, ZAVODY KLEMENTA GOTTWALDA, NARODNI PODNIK. Dec. 21,1956, No. 39032/56. Class 51 (1). Safety-apparatus for a gas-fired furnace comprises a gas analyser 1 which automatically monitors the gases leaving the combustion chamber A for the presence of unburnt gas, a gas shut-off valve 5 in the fuel supply pipe C and electric circuit means to automatically close the valve upon the analyser establishing the presence of unburnt fuel. When such fuel is detected on starting up the furnace a relay 7 de-energizes an audible alarm H and opens a switch 8 until the induced and forced draught fans have purged the chamber A. When the switch 8 closes, circuits through a solenoid 5A for actuating the valve 5 and a relay 6B for actuating a motor-driven gas valve 6 remain open unless there is sufficient air flow through the furnace downpass F, so keeping a wiper L of a gauge 3 on a contact strip M, a sufficient flow of combustion air to the burner B, so keeping a wiper P of a gauge 4 on a contact strip Q, and a sufficient gas pressure at the supply end of the pipe C, so keeping a wiper T of a gauge 9 on a contact strip U. If all these desiderata are satisfied a battery V energizes the solenoid 5A and the relay 6B to open gas valves 5, 6. Closing of the switch 8 enables the alarm H to operate to warn the attendant to light the burner. During furnace operation the differential pressure gauges 3, 4, 9 continue to supervise the combustion conditions and, if necessary, act to shut off the gas supply by de-energizing the solenoid 5A.

Filed: 1972-08-24
Abstract: 1406832 Function generators SIEMENS AG 24 Aug 1972 [16 Sept 1971] 39572/72 Heading G4G For the control of steam-generator systems, an electric signal representing enthalpy (i) is derived by analogue means, using a modification of Koch's equation, viz. where i 0  is variable which is a function of t, p and t are normalized dimensionless magnitudes of pressure and temperature and A<SP>1</SP> and B<SP>1</SP> are constants determined by the apparatus. As shown, signals corresponding to p and t are fed respectively to function generators FG2, FG1 having outputs F(p) = const. + 3lnp and E(t)= 14lnt, these outputs being combined in amplifier V 1  and function generator FG3 to produce the exponential term of the equation. The term D(t)=t<SP>-2.82</SP> is generated in FG4 and multilied by the term p in circuit M. The term i 0 (t) can be represented as const.+const. x t and these two components are fed to output amplifier V 2  via respective lines 3 and 1. The various terms are added in the amplifier V 2 . In a modification (Fig. 3, not shown), the term 1/D(t) = t<SP>2.82</SP> is approximated by generating a function H(t) = const. + const.x t and the term p/H(t) generated by a dividing circuit. At relatively high values of pressure, the value of i fails to agree with measured values and a correction term #i is generated by subtracting the analogue value of i from the measured value. This correction is then applied to the analogue output signal.
