[Also in Group XXVII] An engine incorporates in addition to the normal stopping device a second or starting stopping device which is connected to the engine in such a way that it is operable to override or by-pass the normal stopping device when the latter is in the stopping position and thereby allow the engine to be started and run. It is the object of the invention to provide a means of safe starting engines which are swung by hand for starting purposes. In the Figure the engine 15 is provided with a normal on-off switch (not shown). The ignition circuit is provided with a further switch 23 which is spring loaded to the off position but which when pressed overrides the normal switch and completes the ignition circuit. Thus, during starting, the operator actuates the switch 23. Once the engine is running evenly and the normal ignition switch has been switched on, the spring-loaded switch may be released. The starting stopping device may be operated by one of the unbraked wheels of an aircraft or the roller of a grass mower machine or by a cord secured to a fixed point. The stopping device may be the ignition switch, the magneto earthing switch or in the case of gas turbines the fuel shut-off cock.

Fig. 4.-A bottom cup 16 is discharged from the stack by means of reciprocating cams 40 operated by motor 43. When the stack of cups is low, actuator 71 operates to index the turret 19 to replace the stack. When the last stack is depleted actuator 86 operates to indicate that the machine is sold out. The indexing of turret 19, Figs. 5 and 6.-The turret is indexed by motor 60, which, when switched on, rotates its shaft and at the same time moves bodily longitudinally so that its gear 64 engages 62 to rotate the turret. When a stack of cups is being indexed into position, the motor 60 is switched off and falls back into position on fixture 57 so that the turret is free to permit the stack of cups to adjust itself in said position. As a safety factor a spring 90 is provided which is operated by rod 91 displaced by pin 99 of cam 49 operated by motor 43 to ensure that whilst the stack is in said position the spring 90 presses up motor 60 to cause gear 64 to engage with gear 62 to hold the stack securely in position. Additionally cams 100 and 101, also driven by motor 43, are provided to effect the different operations of the vending machine.

In a plate heat exchanger wherein the plates are separated by sealing strips which form the boundaries of the interspaces between the plates, one heat exchange medium flowing through alternate interspaces and a second medium flowing through the remaining interspaces, bracing members are fitted between adjacent plates at the places where the heat exchange media enter and leave the interspaces to prevent warping of the unsupported thin plate members at these places. Each bracing member is of sheet metal, with tongues bent out normal to the plane of the member, all in the same direction, the tongues being curved lenthwise, their lengthwise direction being substantially parallel with the flow direction of the respective heat exchange medium. Various tongue configurations are described, e.g. Figs. 4 and 5, the height of the tongues not necessarily being as great as the width of the cut-outs from which they are bent. Where the heat exchanger plates have grooves in which the sealing strips are seated, the tongues may register with the sealing strips, the bracing members being fixed to one of the plates. Where a sealing frame 16, Fig. 2, is used between adjacent plates, the bracing members 2 may be fixed to the frame.

Abstract: 846,062. Pressure gauges. NEW YORK AIR BRAKE CO. Dec. 23, 1958 [Feb. 25, 1958], No. 41441/58. Class 40 (1). In a pressure-gauge of the type where the temperature of an electrically-heated filament, as measured by a thermocouple, is used as a measure of the pressure of the gas in which the filament is mounted, the filament has a fixed resistor mounted in parallel with it which is of such a value that, with a standard current applied to the combination, a standard response is obtained from the thermocouple at a predetermined pressure, thus making the filament units interchangeable in the preferred apparatus. Preferably the fixed resistance has a temperature coefficient of resistance related to that of the meter used to indicate the thermocouple output so as to compensate for temperature changes. Fig. 1 shows the preferred circuit in which two filament units 21, 22, are shown. In this circuit with the switches in position b, current is supplied from the supply through transformer 11 and Barreter 12 to the resistors 13 and 16 and rectifier 17 all in parallel. In this condition, 13 is adjusted for a standard reading on meter 18 to standardize the current to be supplied to filaments 23 and 24 during the measurements effected on positions c and d of the switches. While gauge unit 22 is being used for measurement, filament 23 of unit 21 is connected in parallel with resistor 14 in order to preheat unit 21 ready for use, similarly while 21 is in use 22 is preheated.

As described, luminance signal Y, from decoder 7, is compared with preset voltages at 14, 15, an output from 14 indicating Y is below 20% of its maximum and from 15 indicating Y is above 75%. Colour saturation below 20% is detected by circuit 18 to which normalized colour difference signals are supplied. Provided the inverse of the blanking signal, A, is also received, gate 26 closes switches 27, 28 when a near white signal of low saturation is detected. The normalized colour difference signals are then integrated by circuits 29-32 and 33-36 over 2 or 3 frames, the resulting outputs being connected to colour corrector 2 for correction of colour balance in the white area, the ratio of the control signals for the two colour differences being determined by control device 37.

Circuit 50-63, includes amplitude limiters 53, 54 for limiting the colour difference signals to 10% of maximum, and AND gate 50 having two negative terminals to which the outputs from comparators 14, 15 are fed, the circuit correcting colour balance in areas between black and white. If the three colour signals R, B, G are available then an OR circuit comprising 3 diodes is substituted at the positive and negative inputs of comparators 20, 21 respectively. Storage arrangements may be added after the integrating circuits for storing the signals through blanking periods when the integrating circuits have time constants of less than 1 frame.
