Abstract: 1,233,758. Gas analysis. GENERAL ELECTRIC CO. Dec.23, 1968, [Dec.26, 1967], No.61075/68, Heading G1B. Apparatus for determining ammonia and sulphur dioxide in a carrier gas such as air comprises a reaction chamber 10 having an inlet 10 for the gases and an outlet 12 leading to a condensation nuclei detector, the chamber 10 containing a source of acid vapour e. g. a wick like body 30 impregnated with 20% hydrochloric acid, and a corona discharge chamber 15 having an inlet 17 for uncontaminated ionizable gas such as air and an outlet 21 leading into the chamber 10, the chamber 15 containing a corona source 16 and an opening 25 being provided between the chambers 15, 10 together with a closure 26 which enables ultraviolet light from the source 16 to be selectively allowed to pass to or prevented from entering the reaction chamber 10. In use air containing ammonia and sulphur dioxide is passed into the chamber 10 and with the closure 26 open, both ammonia and sulphur dioxide react to produce condensation nuclei a count being taken in the condensation nuclei detection. The closure 26 is closed and in the absence of ultraviolet light, the sulphur dioxide will not count, so the count taken in the detector will be due to ammonia alone. Thus both constituents can be determined. In place of the opening 25 and closure member 26 a separate ultraviolet light source may be provided in the chamber 10.

Abstract: 1,251,673. Control of A.C. motors. DEXIONWHARTON CRANES Ltd. 17 Sept., 1969 [3 Aug., 1968], No. 37134/68. Heading H2J. A slip-ring motor is coupled to the drive wheel of a mobile gantry crane through wormgearing. In one embodiment, a dual-position push-button controller is suspended from the crane by a flexible cable, the rotor circuit being closed when the button is depressed to a first position. When the button is further depressed to a second position, the rotor resistance is progressively removed by timed contactors. To stop the crane, the push-button is released to re-introduce the rotor resistance before switching-off. The crane is thus gradually decelerated before the full braking effect of the worm-drive is applied. In other arrangements the resistance is varied by a drum controller on the crane, or a push-button switch is located at a remote point. A multi-position pushbutton controller may be used, or the contactors may be associated with a radio controller.

Abstract: 1,266,625. Toaster. ELTROLUEDE SCHMIDT & CO. Oct.20, 1969, No.51380/69. Heading A4D. An electric toaster has a slider 5, holding most of the moving parts including the toast supports 34 and guided by the rods 4. The knob 33 is used to depress the slider 5 to the toasting position where it is retained by the hook 17 engaging with the tongue 21 of the bi-metal strip 22. The degree of engagement and therefore the required disengaging movement of the bi-metal strip is set by means of the knob 33 which, when rotated, moves the slider 11 and thus the ledge 13 in a vertical direction whereby the point of contact of the ledge 13 and the sloped portion 32 of the switching hook 17 is altered thus determining the limit of travel of the switching hook 17. In this position two of the contact springs 27 make, while the third breaks. This switches on the main heater and also the bi-metal strip heater 23. The bi-metal strip then deflects until the switching hook 17 disengages allowing the slider 5 to rise under the influence of the spring 19, until the hook 17 engages the edge 30 of the support 24, the bimetal strip heater contact then breaks, and when the bi-metal strip recovers it pushes the hook 17 off the edge 30 thus allowing the slider 5 to rise to its normal position to complete the cycle and turn off the main heater. If premature termination of the cycle is desired the knob 33 may be lifted which tilts the bracket 6 about its top edge and the lug 16 pushes the hook 17 to its disengaged position.
