Title: Device for producing acoustic power
IPC: H04M19/04
Filed: 1971-11-19
Abstract: 1367157 Vibrators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Nov 1971 [24 Nov 1970] 53862/71 Heading G5J A device for producing acoustic power in response to ringing signals comprises an electroacoustic converter provided with an acoustic resonator, a two-port untuned negative resistance amplifier and a supply device to convert the ringing signals into a supply voltage for the amplifier, characterized in that the electroacoustic converter is connected across the two ports of the amplifier and is constituted such that the modulus of the electrical impedance of the converter is a maximum when the argument of the impedance is zero. When an A.C. ringing signal is applied to 103, 103<SP>1</SP>, Fig. 1, the diode bridge rectifier 102 and smoothing capacitor 104 produce a D.C. supply voltage pulse between terminals 105 and 113 which excites the electro-acoustic converter 100 and produces a damped electrical oscillation across 107 and 108. The first half period of this oscillation causes transistors 109, 110 of the amplifier 101 to conduct and these transistors are rapidly bottomed due to regenerative feedback from port 106 through transistor 109 to the base of transistor 110, thereby producing a negative going pulse at the collector of 110 which is applied to the electro-acoustic converter 100. The second half period of the original damped oscillation caused by the supply pulse results in the transistors 109, 110 being very rapidly switched off, again due to regenerative feedback. The application of this negative going pulse to the converter 100 results in another damped oscillation being produced and the cycle is continued. In an alternative embodiment, Fig. 4 (not shown), the amplifier 101 is modified to incorporate N-P-N transistors only.

Title: Automatic regulating device for pit furnaces
IPC: C21D11/00
Filed: 1970-11-16
Abstract: 1318627 Burner control SOC ITALIANA IMPIANTI SpA 16 Nov 1970 [17 Nov 1969] 54479/70 Heading F4T [Also in Division G3] In an automatic temperature controlling system for a pit furnace for heating metal ingots the heating power of an inner and outer coaxial burner arrangement of the furnace, is controlled during an initial heating up period in dependence upon temperature of the furnace space walls sensed by a thermoelectric sensor 24 (Fig. 1), and during a subsequent "soaking" period at reduced heat output, (the inner burner only being used), in dependence upon combustion gas temperature sensed by a thermoelectric sensor 34 in the combustion gas waste flow pipe 3. Operation.-At the beginning of a heating up period a control device 26 is connected to wall temperature sensor 24 only and throttle elements 22, 23 are open in pipelines 16, 18 supplying air and fuel respectively under pressure produced by air and fuel blowers 17, 19 respectively, to both inner burner 7, 8 and outer burner 5, 6. Also throttle elements 20, 21 in air and fuel pipes respectively to the outer burner 5, 6, are open. Thus both burners operate at maximum power, according to the degree of opening of the main throttles 22, 23 which is controlled by a device 28 such as to maintain a predetermined ratio of air/fuel flow rate, the respective flow rates being measured by instruments 27, 29. When the wall temperature reaches a predetermined value which is higher than the permissible maximum surface temperature of the ingots, the control device 26 operates a motor 120 to gradually close the air pipe throttle 20 of the outer burner. Instrument 27 responds to this reduction in air flow and control device 28 operates a motor 121 to close fuel throttle element 21 of the outer burner, thereby maintaining the said air/fuel ratio. A pulse produced when the wall temperature sensor 24 senses the predetermined maximum temperature therefor, switches over the control device 26 from the wall sensor to the combustion gas sensor 34. Intensive turbulence in the furnace gases assists in transferring heat from the walls to the ingots. When the temperature of the combustion gases reaches a predetermined maximum value which is still lower than the maximum permissible surface temperature of the ingots, the control device 26 operates motor 122 to gradually close the air throttle 22 which is common to both burners. The control device 28 simultaneously closes fuel throttle 23 by means of motor 123 until gradually the inner burner is turned off. As shown, Fig. 2, the inner burner 7, 8 receives air via a duct 13 and fuel via pipe 15 while the outer burner 5, 6 receives fuel via pipe 11 and air via pipe 9. The air chamber 5 is connected to a ring of air outlet nozzles 10 (detailed, Fig. 3, not shown).

Title: Analog to digital converter
IPC: H03M1/00
Filed: 1966-12-12
Abstract: 1,106,840. Analogue to digital converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. 12 Dec., 1966 [20 Dec., 1965], No. 55464/66. Heading G4H. In an analogue to digital converter of the type in which a counter is incremented to numerically approximate to the magnitude of the analogue input by output pulses from a variable frequency oscillator, the frequency signal is a non-linear function of the difference in magnitude between the analogue input and the count stored in the counter. In one embodiment (Fig. 4) the analogue input signal is compared in a differential amplifier 114 with an analogue signal representing the count in a reversible binary coded decimal counter 120, the difference signal being applied to a voltage controlled oscillator 118, the output from which is a pulse train, the frequency of which is logarithmically related to the input signal. The difference signal is also fed to a polarity detector 116 to determine whether the pulse train from the oscillator 118 should be counted positively or negatively in the counter 120. The outputs from the counter, which may be connected to recording means or a display, are connected to switches 140 so that in accordance with the output either a reference potential or ground is applied to all the resistances 146, a voltage proportional to the count thus being produced on line 132. In a further embodiment (Fig. 5) the variable frequency oscillator 218 delivers a pulse train the frequency of which is directly proportional to the error signal, but the switches 240 connected to the outputs of the reversible counter 220 are such that reference voltages are only applied to the resistances 222 if the switches are held in their one state for a predetermined time so that if the error signal is large the counter is incremented at a higher rate than if the feed-back were linear. The two embodiments may be combined to give a single conversion circuit employing non-linear feedback to control a non-linear oscillator.

Abstract: 1375005 Analogue to digital converters BODENSEEWERK PERKIN-ELMER & CO GmbH 8 Dec 1971 [10 Dec 1970] 57077/71 Heading G4H A circuit for integrating a voltage with respect to time comprises a voltage divider capable of being switched in steps, an integrator which supplies a string of pulses at a frequency proportional to the input voltage, a counter which is controlled by the signal frequency through a range selector and limit value switches which switch the voltage divider and range selector in opposite directions when preset valves of the input voltage are exceeded; the switching occurring on production of a counting pulse. As described the integrator is a Miller integrator with associated devices which produce a counting pulse when a predetermined integrated voltage is reached and which is then reset by a standard voltage time pulse of opposite polarity to the the input voltage. Limit value switches K1, K2 (K1 responding to a lower value than K2) are connected by inverters (I1, I2) and "AND gates" (G1 G2, G3) to flip-flops (F1, F2, F3). The flipflops F1, F2, F3 are partially enabled when the input voltage is respectively (a) less than K1 response, (b) between responses of K1 and K2 and (c) greater than K2 response and pulses from the integrator (A-D-W) fully enable the flip-flops and select the correct range on the counter and input voltage divider.

In Fig. 1, inlet 8 opens through the pipe wall, and annular flange 10 assists in generating the helical flow which detaches solids from the upstream side of the screen. A valve 11 generates a helical flow in the feed water upstream to cause some centrifugal separation of solids from the feed water. In Fig. 2 (not shown) the upstream helical flow is created by a tangential inlet (13) and a conical end closure 15 in the pipe section, assisted by an upstream tangential inlet 20 for flushing water. The downstream flushing water inlet comprises an axial feed tube with tangential, outlets (18, 19), and in Fig. 3 (not shown) a similar feed tube is axially adjustable to clean various parts of the screen. Fig. 3 also illustrates an upstream vane (21) and an inclined, tangential, upstream flushing water inlet (24), located in a throttled portion of the pipeline adjacent the screen. In Fig. 4 (not shown) upstream helical flow is induced by delivering a proportion of the feed water through inclined tangential inlets (25), this arrangement supplementing the other arrangements. In Fig. 5 (not shown) the flushing water is fed to the downstream side of the screen partly through an inclined tangential inlet 8 and partly through a nozzle (26) which directs it towards the screen tip. This arrangement is said to render the screen pressure drop more uniform across the the pipeline diameter.
