Abstract: 1,234,081. Analogue/digital converters. NATIONAL RESEARCH DEVELOPMENT CORP. 17 Feb., 1969 [22 Feb., 1968], No. 8557/68. Heading G4H. [Also in Division H4] In an analogue-digital converter (Fig. 4) the unknown phase of an input signal IP is compared with a signal of reference phase CV. The comparator is a phase discriminator PC delivering a voltage signal, the magnitude and polarity of which depends on the phase difference, to a voltage-to-impulse transducer VP which pulses a counter UDC in a direction determined by the polarity of the phase discriminator output. The eight bit digital output of the counter controls the phase shift of a reference signal from a three phase generator to generate the reference phase signal CV. The count at equality may be recorded on tape or transmitted over a radiolink. To control the phase shift of the reference signal, four of the counter outputs are connected to a diode matrix decoder EC delivering a signal on one of twelve leads to an associated transistorized gate. Each gate also receives an input from a phase divider delivering twelve signals phase displaced by 30 degrees, the enabled gate feeding the selected phase displaced signal to an output lead. The output lead is connected to capacitors having binary weighted capacitances, the capacitors being energized by contacts of relays controlled by the remaining four digital bits to and the phase of the reference signal. Alternatively a digital signal read from a tape T (Fig. 1) may be used to control the gates of the phase divider PD and relays A-D so that an analogue signal the phase of which depends on the digital input signal is obtained from phase shifter CP.

Abstract: 1,265,164. Disc brakes. SOC. ANON. FRANCAISE DU FERODO. 21 Feb., 1969 [22 Feb., 1968], No. 9547/69. Heading F2E. A disc brake comprises a frame 18, a disc 10, two brake shoes 14A, 14B pivoted on two pad levers 21A, 21B, one on each side of the disc, electromagnetic and hydraulic actuating means 29, 60 and mean for automatically taking up pad wear. Each shoe includes a lug 15, attached by a pin 16 to a bracket 17 of the frame, and four transverse webs 19A to which a pad lever is pivoted. Each lever 21 comprises two plates 22A, 22B interconnected by hinge control and bearing pins 23A, 24A, 25A. The levers are interconnected by a tie-rod 98 and springs 26 attached to the ends of pins 25A, 25B. Control pin 24A is resiliently mounted in two fixed parallel tie-rods 27 attached to the yoke 28 of an actuating electromagnet 29 and control pin 24B is pivotally attached to armature 37 of the electromagnet. A cylinder block 60 mounted on the end of rods 27 contains an hydraulically actuated piston which reacts against the pin 24A. The pads are held against the disc in the absence of electric current by a stack of Belleville washers 53, the tension being adjusted by a plug 45. The brakes are released by supplying current or by tightening a nut 50. With current on, the brakes can be gradually applied hydraulically when the resilient mounting 33 of pin 24A is deformed. The pins 25A, 25B are maintained by a spring 26 against a tapered block 71 against which they pivot during brake application. To adjust for wear, rod 98 is mounted on lever 21B and connected to a lever in a bearing 70 on lever 21A which permits clockwise movement only, with some clearance to allow for brake release, so that the effective length of rod 98 is reduced if wear occurs. On retraction the levers 21 first pivot about pins 25A, 25B and then about the effective ends of rod 98 when pins 25A, 25B are pulled apart. This allows block 71 to fall to a new position until it finally actuates a switch 85 which operates a warning light, stops current to the electromagnet 29 or to the supply circuit of the driving circuit to which the disc is coupled. In another embodiment, the pins extend through the levers 21, the end of one pin 24 is fixed to the frame, the end of the other pin pivoted on the frame and the other ends attached to the actuating means.

Abstract: 1318258 Measuring temperature acoustically GENERAL ELECTRIC CO 24 Aug 1970 40649/70 Heading H4D A fluidic temperature-sensing system comprises two fluidic sensor elements providing respective different output signals which are functions of the temperature being sensed, and means for deriving a temperature function signal proportional to the difference between the two output signals, each sensor element having, for a step charge in the temperature being sensed, a short term time constant and a long term time constant in its response, such that one sensor element has at the expiration of its short term time constant a change in output signal value different from the output signal value change of the other sensor element at the expiration of the short term time constant of said other element, the difference between the two output signals at the expiration of the short term time constants having a predetermined relation relative to the difference at the expiration of the long term time constants. In the Fig. 1, embodiment for sensing the temperature of gas in a turbine 12, a sample of the gas enters fluidic oscillators 18a, 18b via nozzles 38, impinges on flow dividers 44 and sets up oscillations in vented resonant cavities 40, 42. The oscillators are constructed to have different respective frequencies (both a function of gas temperature) and the frequency difference is extracted by detector 22 (Fig. 3, not shown), comprising a fluidic amplifier and rectifier. The detector output is converted by transducer 24 to a control signal for temperature indicator 28 or turbine control. The short term time constant C 1  and C 2  (Fig. 4) may be made equal (they are a function of gas flow rate), and the long term time constants C 3  and C 4  (a function of gas flow rate and thermal mass of the fluidic oscillators) may be made equal. If the long term rates of change of the two frequencies are made equal, then the difference frequency (Fig. 5) after the short term time constant period will be the same as after the long term time constant period, i.e. the overall response time of the sensing system to the temperature step is effectively reduced to the short term time constant. Alternatively, if the long term rates of change of the two frequencies are made unequal (Fig. 6), the difference frequency can be made greater after the short term period than after the long term period (Fig. 7), thus providing a control signal which "leads" the temperature change and can be used to compensate for lag in the response of a controlled component such as indicator 28. The two temperature sensor elements may generate output signals having a parameter other than frequency (e.g. pressure) functionally related to the temperature.
