Title: Method of and apparatus for testing the thermal resistance of  a transistor
IPC: G01R31/26
Filed: 1974-05-06
Abstract: 1468161 Measuring transistor parameters LUCAS ELECTRICAL Ltd 6 May 1974 [15 May 1973] 23001/73 Heading G1U The thermal resistance of a transistor is measured by a method including the step of determining the rise in junction temperature by measuring the change in base-emitter or base-collector voltage after passing a known collector current through the transistor for a predetermined time which is too short to cause any rise in the transistor mounting temperature. The transistor 20 is fixed to a mounting base but nuts tightened by a torque wrench and has a copper mounting washer with all surfaces being smeared with heat conducting silicone grease. The rise in junction temperature is measured by determining the rise in base-emitter voltage which is temperature dependent in a manner which has been previously determined. A fixed base current I ref , flows into the transistor while switch 23 short circuits the current source 21, and sample and hold 29 measures the base-emitter voltage. Switch 23 then is turned off and a current I c  flows through the transistor. After the switch is turned on again, sample and hold 30 measures the new base-emitter voltage. Amplifier 26 maintains the collector-emitter voltage constant during the flow of I c . The thermal resistance is given by the quotient of junction temperature rise and power dissipated (I c .V CE ).

Filed: 1948-09-06
Abstract: 652,132. Determining physical qualities of materials. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 6, 1948, No. 23409. Convention date, Sept. 18, 1947. [Class 37] Apparatus as described in Specification 643,367 for detecting certain finely divided substances in a gas by bringing the gas into contact with a positively charged electrode to produce a flow of positive ions is characterised by the addition of audible or visual means for indicating the presence of the detected substance. As shown in Fig. 1, a pulsating current is produced in transformer 19 by the alternate charging of condenser 17 by the ion current in discharge cell 1, and discharging through discharge tube 20, thereby producing an audible note in a loud-speaker 25 attached to the secondary of transformer 19, whose frequency is indicative of the ion current and therefore of the degree of concentration of the detected substance. In another embodiment, Fig. 2, the discharge cell 1 together with resistance 26 and potentiometer 27 form a bridge, whose unbalance current is amplified by valve 28 and indicated by a meter 33 in the anode lead. The anode current may also produce a pulsating current by charging condenser 40 in parallel with discharge tube 35, the resulting A.C. being fed to a loud-speaker 41 via an amplifier valve 42. Visual indications may be obtained from discharge tubes 20, 35, or the loud-speakers 25, 41 may be replaced by suitable light producing means. Specification 652,233 also is referred to.

The end 12a is guided by springs 13, 14 into the slot 11c and runs round inside the spool until it contacts stops 11d (Fig. 3) whereupon the film bulges adjacent the slot and lifts the ratchet so that the spool can be rotated. Perforations of the film then become engaged in the tooth flanks 11b. A restraining member 16 prevents the spring 14 springing out from the back wall when the camera back 2 is opened after the film has been re-wound into the cartridge. More than one slot may be provided.

Abstract: 748,516. Toy aircraft. DAUWE, C. F. Aug. 26, 1953 [Sept. 17, 1952], No. 23576/53. Class 4. A toy glider towed by a cord has one wing 1 pivotally secured to a stub 2 on an axis X-X<SP>1</SP>, the hinge incorporating a torsion spring 4 which tends to move the wing downwardly against the action of a flexible tie 5 looped at 6 round the tip of the opposite wing. Before launching, the wing 1 is given an incidence greater than that of the opposite wing and when towed the glider can be caused to veer to the left or right dependent upon the strength of the pull applied to the towing cord. A slight pull will not alter the pre-set incidence of the wing 1 and the model will move to the left, whereas a stronger pull will cause the wing 1 to rise against the action of the spring 4 with a consequent decrease in its incidence, which will cause the glider to veer to the right.
