Abstract: 1,229,349. Analogue/digital converters. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Sept., 1969 [14 Sept., 1968], No. 44936/69. Heading G4H. In an analogue/digital converter in which a frequency signal (FM, Fig. 1, not shown) proportional. to a sample of the analogue input (PAM) is applied (via decoupling transistors) to different resonant elements (R1-R2<SP>n</SP>) each coupled to a voltage node (B1-B2<SP>n</SP>), the voltage signal at each node is integrated by an associated capacitor, the capacitor receiving the lowest signal enabling a gate TOR (Fig. 2) to generate a digital output. As described the gates are connected to the columns of a diode matrix K, timing pulses T<SP>1</SP> at the sampling frequency being applied to the gates so that parallel signals representing the resonant element in which a standing wave is set up are fed into a shift register SReg. The shift register is read out serially. The gate circuit preferably include thresholds so that when the frequency signal rises between the resonant frequency of two elements, resulting in small voltages on two nodes, the numbers of two neighbouring resonant elements are recorded in the register. By using a Gray code the number of only one of the two enabled gates is stored. In another embodiment three gating circuits may be enabled by the voltages on the nodes, the gates being connected via three diode matrices to three registers (Reg 1, 2, 3, Fig. 3, not shown) the outputs from which are averaged, the average being stored in a shift register and read out serially.

Abstract: 1,232,967. Photographic processing apparatus. EASTMAN KODAK CO; Jan. 16, 1969 [Jan.18, 1968], No. 2521/ 69. Heading G2A. A predetermined quantity of processing liquid in a container 21 is heated prior to its introduction into a processing tank 3, so that its average temperature during a predetermined period in the tank is substantially the same as its known optimum processing temperature. The temperature of the liquid in the container 21 is sensed by a probe 32 and the ambient temperature of the liquid by a probe 33. These probes exert a fluid pressure, proportional to the temperatures sensed, through a common tube 37 to a diaphragm (39), Fig.2 (not shown) which, under sufficient pressure, expands and disconnects switch contacts (40, 44) in a circuit for heating coils 22. To vary the average temperature attained by the liquid, the position of the switch contact (44) may. be adjusted to vary the diaphragm pressure necessary to disconnect the coils 22. In use, liquid is introduced into the tank 3 which is tilted to the position of Fig. 1, rotated, righted and drained. A different liquid is then introduced from another container 21.

Abstract: 1,250,114. Tubular heat exchangers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 Feb., 1970 [18 Feb., 1969], No. 8645/69. Heading F4S. In a heat exchanger comprising a plurality of arrays of heat transfer units 31 arranged one above another in a chamber 1, the units in each array extend radially between one or more distribution manifolds 15 and a common collection manifold 3. Each heat transfer unit 31 comprises a plurality of spaced apart small bore tubes (of diameter #0À125 in.) extending between tube plates held in annular flanges 35 and 37. The tubes 33 in each unit are surrounded by a sleeve 39 to which a frusto conical wall is 41 secured by annular pressure seals 43; the wall 41 defines annular compartments 51, 53. As shown cold gas to be heated enters a circular toroidal inlet manifold 11, which in turn communicates with the upper ends of circumferentially spaced vertical distribution manifolds 15, and flows through the tubes 33 into the manifold 3 and out through a port 47. Heating gas entering through inlet port 49 flows upwards through compartment 51, laterally, in counter current to the flow of gas to be heated, through the passages enclosed by the sleeves 39 into compartment 53, to finally leave through outlet port 55. The units 31 can be withdrawn for replacement or repair through a flange cover plate 9. In an alternative embodiment (Figs. 4 and 5, not shown) wherein water is used to cool a gas, the heat transfer units extend between annular distribution and collection manifolds (67, 63), the water being passed through the tubes.

Abstract: 1,250,309. Switchgear structures; gas blast circuit breakers. BROWN, BOVERI & CO. Ltd. 28 May, 1970 [30 May, 1969], No. 25693/70. Heading H1N. A metal clad switchgear structure includes a single phase feeder having component parts contained in gas chambers separated by bulkheads and insulated by a gas under pressure which gas has a series connected flow path through the chambers, some of which are interconnected by flow-restricting elements. In Fig. 3, a three-phase switchgear system is contained within a single metal cladding having three identical compartments subdivided into gas chambers, which, with the exception of chambers R4, S4, T4 and R5, S5, T5, associated with respective gas blast circuit-breakers RL, SL, TL, are combined in a single gas flow path. The flow path is via the high pressure bus-bar compartment 1 and non-return valve V1 to the isolator chambers T3, S3,R3 through non-return valve V2 to the voltage transformer chambers T6, S6, R6, and via valve V3 to the earthing chamber T7, S7, R7, finally passing through valve V4 to the earthing and cable box chambers T8, S8, R8. The high pressure chambers, T5, S5, R5, of the gas blast circuit-breakers are also connected to the high pressure gas reservoir Sp, this via check valves V5, V7 and reducing valve VR1. The breakers low pressure chambers T4, S4, R4 are connected to Sp through a reducing valve VR2 to maintain the pressure, and through valves V8, V9, V10 and filter F to the low pressure side of compressor K for the passage of gases resulting from the operation of the breaker contacts. If, as in Fig. 3, the compressor is common to both the circuit-breaker and the other chambers then it must be available for immediate switching to the gas circuit of the circuit-breaker, e.g. if the pressure difference between the H.P. and L.P. parts of the breaker becomes too low. Solenoid valves responsive to gas pressure or simple gas flow restrictions may be used instead of the non- return valves. The gas flow may or may not be continuous, in the latter case the compressor may be disconnectable from the inlet and outlet valves VA, VE, respectively, Fig. 1 (not shown). A flow-meter D indicates the state of the gas pressure in the chambers either continuously or when the valve VE is opened. In Fig. 2 (not shown), the series path between the chambers of the phase feeders is replaced by three parallel paths, one for each feeder.

Abstract: 1314869 Ultrasonic detection devices IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 30 Sept 1971 [9 Oct 1970] 48059/70 Heading H4D  A test piece is scanned by a probe which emits an ultrasonic signal and receives the resulting reflected signal, the reflected signal being converted into an electrical signal which is passed to four amplitude detectors at a receiver. In a first embodiment each amplitude detector is connected to a respective light source which scans a respective photographic film in synchronism with the scanning of the test piece by the probe, and each amplitude detector is arranged to produce an output when the amplitude of the received signal is above a different predetermined level, so that different amplitude levels of the received signal cause four, three, two, one, or none of the light sources to light up and examination of the four photographic records gives a measure of the received signal amplitude and hence the severity of any flaws in the test piece. In a second embodiment the four light sources are replaced by one light source which scans a colour photographic film, the light source containing a central white bulb surrounded by alternately blue and red bulbs (or white bulbs with blue and red filters). On reception of a high amplitude signal all bulbs are lit and the bulbs are cut off by the detectors as the signal amplitude decreases in the order, the white bulbs, half the red bulbs, the remaining red bulbs, and the blue bulbs, so that the colour of the resulting film indicates the severity of flaws. In this case the bulbs may be faded from on to off in response to the signal from the respective detector to produce a range of hues and saturations. The test piece may be scanned in a series of straight lines or in a spiral scan.
