Abstract: 1415759 Ultrasonic inspection devices; gain control arrangement ERASMUS UNIVERSITEIT ROTTERDAM 28 Dec 1973 [28 Dec 1972] 59972/73 Headings H4D and H4R In an ultrasonic pulse-echo inspection device having an echo amplifier whose gain is varied with time by a control voltage so as to compensate approximately for the echo strength dependence on propagation path length, the control voltage can be adjusted to have pre-set values at at least two instants within a transmission-reception period and is produced by integrating the output of several differential amplifiers in turn. Fig. 2 shows a control voltage generator for use in providing the gain versus time function of Fig. 5. Slider potentiometers 1-5 define the voltages e 1  to e 5  which the control voltage is to have at successive break-points of the function, and their settings also serve to "display" the function. By means of difference amplifiers 21-25, electronic stepping switch 31 and integrator 33, c, the voltages e 1 , e 2 -e 1 , e 3 -e 2  and so on are integrated in turn in respective successive sub-divisions of the pulse-echo period. The integrator output is used to vary the sourcedrain resistance of an FET (Fig. 4, not shown) coupled to gain-determining pins of a commercially-available (specified) differential video amplifier acting as the echo amplifier. The device is useful in medical diagnosis and non- destructive testing of materials.

Title: Improvements relating to storage heaters
Inventor: RUSSELL WILLIAM MORRIS
IPC: F24H9/20
Filed: 1968-12-20
Abstract: 1277589 Electric Storage heaters SIMPLEX ELECTRIC CO Ltd 18 Dec 1969 [20 Dec 1968] 60834/68 Heading F4U In an "off peak" electric storage heater comprising a heat storage body H incorporating heating resistors R1, R2, R3 and a control temperature thermostat TH1 and a cut out thermostat TH2, the power dissipation of the heating resistors during a charging period is controlled selectively to any of a plurality of different values. A manually operable charge rate control switch 51 with contacts 51a, 51b, 51c is provided for controlling the number of heating resistances brought into use. In one mode of operation all three contacts 51a, 51b, 51c of switch 51 are closed to provide full rate of heating below the control temperature X. On reaching the control temperature contacts S2 of the thermostat TH1 open whereby current passes through resistance R4 and causes heating of bimetal 25 which in turn opens contacts S3 to cut off the current flowing through a solenoid L1 with the result that the contacts 55a, 55b, 55c open to cut off current to the resistors R1, R2 & R3. The circuit components are chosen to provide a small ratio of closed to open time for the contacts S3. The contacts 55b, and 55c remain open when the contacts 53 close again so that no further current flows through R2 and R3. If the contacts 52 fail to break for any reason the cut out thermostat TH2 comes into operation. The above arrangement maintains the mean temperature of the heat storage body at the control temperature XC until the end of the off peak charging period.

Title: Rotation Sensor
IPC: G01P13/00
Filed: 1978-12-08
Abstract: A sensor, for sensing when rotation of a shaft 3 is reversed, comprises one component 11 carried or driven by the shaft which drives a second component 10 from an operative (full lines, Fig. 3) to an inoperative position (dotted lines, Fig. 3) during rotation in one direction and vice versa when rotation is reversed. The drive linkage between components 10, 11 permits slip between them when the second component reaches the end of its travel e.g. a stop 13 or 14. For example the linkage is magnetic; shaft 3 carries a follower 11 and second component 10 is a magnet pivotting about an axis coincident with the shaft axis of rotation. The sensor finds especial use in centrifuges which employ reversed current braking of the drive motor, the magnet 10 in the sensor tripping a reed switch 15 to switch off the reverse current when the shaft 3 begins to rotate in the reverse sense. Instead, magnet 10 may interrupt a photo-electric output. <IMAGE>

Title: Treatment of spent grains
IPC: A23K10/38
Filed: 1979-04-20
Abstract: Spent grains (brewers' grains) are treated with an alkali to render them more digestible to animals, particularly to ruminants. Caustic soda is a suitable alkali and may be added in solid form or in solution. Treatment should last at least for one hour. The weight of caustic soda added may be between 5% and 10% of the dry weight of the grains. It is normally unnecessary to neutralise the alkali if the treated grains are to be used without delay; but if the treated grains are to be ensiled or otherwise stored it is preferable to neutralise the alkali with a mineral acid such as sulphuric acid or hydrochloric acid.
