Abstract: 1,237,981. Testing drugs. G. PANTEL. 28 Oct., 1970, No. 14699/69. Heading ASK. The efficacy of a drug is determined by carrying out tests and empirical estimations before and after administration of the drug to a test subject to determine an adequate number of "functional body magnitudes" and deriving the squares of the differences thereof from their corresponding "optional values" (the empirically estimated individually attainable value which is optional for the survival of the particular subject, and at a given exertional activity whether basal or otherwise). Comparison of the sums of the squares derived from the measurements made before and after drug administration gives an indication of the effect of the drug on the ability of the subject to survive in "living ability units". This, the manufacturer may use to determine whether to continue with the development of the drug or whether to market it. No particular drug or specific tests are described. Typical "functional body magnitudes" are: maximal alpha wave voltage, survival intelligence quotient, blood haemoglobin concentration, left (or right) ventricular work per (heart) beat, greatest horizontal systolic diameter of a sharply out-lined heart kymograph taken at an unvaried selection of exposure factors, body fluid glucose concentration and body heat.

Abstract: 1,239,223. Defrosting. HERON ELECTRICAL DEVICES Ltd. 9 Aug., 1968 [30 June, 1967], No. 30200/67. Heading F4H. In a refrigeration unit having a cold output radiator through which air is blown by a fan F, defrosting of the radiator by an electric heater H is initiated by a switch PA, which is responsive to the strength of the air flow through the radiator, and is terminated by a thermal switch TH1, which is responsive to radiator temperature. The switch PA is a reed switch which is closed by a magnet NS mounted on a pivoted flap X in the radiator air stream when the latter falls below a given strength. A second reed switch PB is closed by the magnet simultaneously with the switch PA. As illustrated, the various switches are in the positions corresponding to normal refrigerating operation. When frost builds up on the radiator, the switches PA and PB are closed by the magnet NS so that, after a delay introduced by a time delay switch D, a relay RA is operated to throw switches RA1 and RA2 thereby energizing the defrost heater H and de-energizing the fan F and the refrigeration unit motor M. When the radiator temperature has risen to 50‹ F., the switch TH1 is thrown, thereby deenergizing the relay RA, starting the motor M and fan F, and de-energizing the heater H. The switch TH1 simultaneously energizes a relay RB which opens a switch RB2 to prevent the relay RA subsequently re-energizing the heater M if the fan fails to start. The relay RB also closes a switch RB1 so that the relay RB remains energized until the fan has started and opened the switches PA and PB. When the radiator temperature has fallen to 30‹ F., the switch TH1 returns to its illustrated position. In a modification, Fig. 1 (not shown), the relay RB and its latching circuit are omitted and a thermal switch (TH2) is included in series with the fan. The switch (TH2) opens at 36‹ F. and closes at 32‹ F. so that the fan is not restarted after defrosting until the radiator temperature has fallen to freezing. As a result, any moisture on the radiator is frozen in place rather than being entrained in the air stream.

Abstract: 1,265,275. Interconnecting A.C. networks. TOKYO DENRYOKU K.K. and MITSUBISHI DENKI K.K. 26 March, 1970 [26 March, 1969], No. 14686/70. Heading H2H. A system for interconnecting two A.C. networks A, B comprises a transformer T having its primary winding serially connected between the two networks and the secondary winding connected across the parallel arrangement of the primary winding 4 and the secondary winding 5 of a further transformer CT which is also provided with a tertiary winding 3 having a switching device 3-such as a thyristorconnected thereacross, the secondary winding 5 having a capacitor C in series therewith and, if desired, an inductor L connectedin series with the primary winding 4. In operation with the two networks A, B, fault-free, the thyristor is non- conductive and the impedance of the interconnecting arrangement is low and power interchange over the link is normal. Should either network become faulty the thyristor is rendered conductive with a consequent increase in the impedance of the link thus preventing the faultless system from feeding power into the faulty system. A three-phase system is disclosed which is provided with two identical interconnecting links in parallel together with circuit breakers for directly interconnecting the two networks.

Abstract: 1302204 Electric storage batteries JOSEPH LUCAS (INDUSTRIES) Ltd 1 July 1970 [2 July 1969] 33329/69 Heading H1B [Also in Division G3] In an electric storage battery 11 the terminal post is formed with a blind bore which extends therethrough to the plate connecting strap 27, the bore having inserted therein a temperature sensitive element such as a thermistor 28 for sensing temperature changes in the battery in use, such as during charging. During charging of the battery using a generator 12, the thermistor 28 is electrically connected to a voltage regulator 15-26 so that the regulating voltage can be altered as changes in the temperature of the battery are sensed by the thermistor. In the charging circuit shown, thermistor 28 is electrically connected to the positive terminal post through the thermistor casing and the other connection is taken by a lead extending through the bore to the junction of resistors 15 and 16. The thermistor acts to change the battery voltage at which the Zener diode 18 conducts with temperature to provide the required temperature compensation. In an alternative arrangement the thermistor may be in an earthed terminal post from which it is insulated and two leads are used, or the thermistor may be placed in series with the resistance chain 15, 16, 17 either directly across the battery or via the ignition switch 13 of a road vehicle.

Abstract: 1302235 Temperature alarms SHORROCK DEVELOPMENTS Ltd 26 Aug 1971 [17 Sept 1970] 44415/70 Heading G4N [Also in Division H3] A temperature alarm system utilizes a junction diode D3 as a temperature sensor and is provided with an automatic fault indicator. As shown, an increase in temperature in the region of the silicon junction diode D3 causes reduction in voltage at termiinal 4 of an operational amplifier A3 which results in a decrease in output voltage from terminal 6. If this decrease is sufficient to cut-off Zener diode D11, transistor TR3 will be cut-off so that the voltage at point E will turn on transistors TR5, TR6 and light the alarm lamp L1. TR5, TR6 remain latched until reset by contacts K. A similar effect will occur if the rate of increase in temperature is excessive, due to the effect of capacitor C2 and field effect transistor TR4. The system is applicable as a fire alarm or as a rate of temperature rise indicator in a refrigerator. Automatic fault indication.-A multivibrator  TR7, TR8 feeds short-duration pulses into the system, the pulses being too short to light the alarm lamp L1. Capacitor C4 prevents the test pulses from latching TR5, TR6. Capacitor C5 is normally charged via resistor R6 but becomes discharged by TR9 by each test pulse. In the event of a fault the failure of test pulses will allow C5 to charge sufficiently to break down Zener diode D10 and turn on TR10 and fault indicator lamp L2. Modifications. Fig. 1 (not shown) relates to a simpler arrangement in which the voltage across the sensing diode D3 is fed to the non- inverting input of the amplifier A3 whilst the test pulses are fed to the inverting input and the rate detecting capacitor is shunted across the Zener diode equivalent to D11 of Fig. 2. Relays (not shown) may be used to operate an audible alarm or to feed a stored message into a line connected to the fire station.

Abstract: 1311089 Internal shoe-drum brakes; indicating brake-application GIRLING Ltd 22 Oct 1970 [7 Nov 1969] 54763/69 Heading F2E The invention relates to internal shoe-drum brakes of the kind in which arcuate shoes 1, 2, Fig. 1, for engagement with a drum (not shown) are mounted on a stationary back-plate 4, and adjacent shoe-ends are separated in the application of the brake by a mechanical actuator linkage including an angularly movable lever 9 pivotally connected at 10 to one shoe and coupled at the other end to applying means such as an inextensible cable 11, and a strut 13 acting between the lever 9, at an intermediate point in its length, and the other shoe 2, and in the off position of the brake the lever cooperates with a back-stop, e.g. 17, Fig. 2, which defines a retracted position determining the braking clearance between the brake shoes and the drum, means 14 for adjusting automatically the braking clearance to compensate for wear of the friction linings being incorporated in the mechanical actuator assembly; it consists in providing an electrically-operated device, e.g. 34, Fig. 2, for indicating when the linkage is in a brake-applying position in which adjacent shoe ends are at least partially separated, the device 34 being actuated by an electrical make and break effected by the engagement and disengagement of the lever with the back-stop. As shown, the lever 9 has an abutment 19, Fig. 2, and the backstop comprises a sleeve 21 of deformable synthetic plastics material which extends into the brake through an opening in the back-plate 4; at its inner end the sleeve has an integral wall 22 through which extends part 26, of the stem of a spring-loaded contact member 27, the outer end of part 26 carrying a metallic head 28. In the "off" position of the brake shown in Fig. 2, abutment 19 is in contact with contact member 27, and the other end of member 27 is in contact with an electricallyconductive plate 29 connected through a battery 33 and a lamp 34 to earth at 35. In operation, during the first movement of lever 9 inwards (to the right in Fig. 2), during application of the brake, a spring 30 maintains contact between member 27 and lever 9, but the resulting movement of member 27 breaks contact with plate 29, so the lamp 34 is extinguished, providing an indication to the driver. In a modification, described without an accompanying drawing, the end of contact member 27 remote from part 26 has a radial projection or flange freely received within an annular recess in the end plate 29, the recess having a depth greater than the axial thickness of the projection or flange, in this case, in the "off" position, the lamp is de-energized. During the first movement of brake application, spring- urged movement of member 27 causes contact between the projection or flange abovementioned and the interior of plate 29, so the circuit is made and the lamp is illuminated.
