Abstract: 552,755. Snap-action switches. TURNER, C. A., and "DIAMOND H" SWITCHES, Ltd. Nov. 27, 1941, No. 15301. [Class 38 (v)] A rotary switch operable in either direction comprises a coiled spring in a casing x, adapted to be strained when a knob z is twisted, the other end of the spring being held, together with a contact structure p rotatably mounted, on a spindle e, until released by a member j. A fixed back plate a has four pressed-out projections b adapted to confine, between two of them, a cam shape m of the release member j until it is moved radially clear by an eccentric l secured to the spindle e and rotated by the knob z. The contact structure then moves through 90 degrees, carrying with it, by the engagement of projection n in a slot o in the structure, the release member j, to a new position. Specification 552,375 is referred to.

Abstract: 807,146. Fire-fighting foam generators. WHITSUN & CO. Ltd., J., and JOSEPH, A. May 17, 1957, No. 15718/57. Class 47. In a foam generating apparatus, nozzle means 22, within a casing 2, has a central convergent nozzle 24 and auxiliary jet apertures 26 radially spaced therefrom which divide a supply of liquid and foam compound under pressure from a pipe section 16 into a central jet and a plurality of auxiliary jets, the central jet being permitted to pass through a central passage 34 in an impeller 32 which is rotated under influence of the auxiliary jets, the vanes 36 of the impeller acting to draw in air between the casing 2 and nozzle means 22 in the direction of the supply of liquid and foam compound, the liquid, foam compound and air being intimately mixed by means provided on the side of the impeller 32 opposite the nozzle 22. The jet apertures 26 in the nozzle 22 are inclined with respect to the normal to the nozzle 22. A circular series of apertures 38 in the impeller 32, radially spaced from the passage 34 by an amount equal to the radial spacing of the apertures 26 and nozzle 24, are inclined in an opposite sense to the auxiliary jet apertures 26, whereby interaction of the auxiliary jets with the aver- -tures 38 causes rotation of the impeller. A peripheral passage 58 defined between members 56, 48, carried by a spider 46, direct the discharges from the apertures 38 inwardly into contact with the central jet discharging through a bore 50 in the member 48, thereby causing the intimate mixing of the liquid, foam compound and air. A cylindrical grating 62 having inwardly extending projections 64, maintains the mixture in its intimately mixed state. The impeller 32 is rotatable upon bearing surfaces provided by collars 30, 44 carried by the nozzle 22 and member 48 respectively.

Abstract: 853,072. Vehicle windows. WILMOTBREEDEN Ltd. May 6, 1959 [May 19, 1958], No. 15945(58. Class 20(3), A window 11 vertically movable in a vehicle rear door 10 shaped so as to fit in part over the wheel arches of the vehicle body and engaging a sealing strip, not shown, on the body when in the raised closed position with the door closed, is guided in the door so that movement to or from a fully raised position will effect an angular movement of the plane of the window, whilst movement to or from a fully lowered position will effect an angular movement of the window in its own plane. As shown, the window 11 extends through a guide slot 12, Fig. 3, formed in a plastic sealing member 12 at the upper end of the door 10 (which terminates at the waist line of the body) and has secured to the lower edge portions thereof a bracket 17 carrying, on axes parallel to the window, two pairs 18, 19 of axially aligned pins or rollers, the upper pair 18, Fig. 1, having a shorter distance apart than the pair 19, and engaging, when the window is in the fully closed position, in the upper converging end portions 16a of the guide tracks 16 within the door and function only when in this position to steady the window, the lower pair of rollers 19 engaging in the respective guide tracks 16 to be wedged between the inclined portions of the guide strips 15 and concave recesses in the guide plate 13, see Fig. 3. When the window has moved away from the closed position the pair 18 leaves the guide track 16 through a gap under the portions 16a to produce a rotation of the window plane to remove the window from the body seal. A pair of pins 20 laterally extending of the window from the bracket 17 engage in respective slots 14 in the guide plate 13 which are so shaped and disposed that when the window is in the fully raised position one pin is above the level of the other to a greater extent than when the window is in the lowermost position to produce a rotation of the window in its own plane to enable the window to be accommodated within the door. In another embodiment a box-section guide member is accommodated within the door with suitable guide slots in its sides and ends to guide pins on the extremities of an L-shaped bracket secured to the window; the slots being so shaped and disposed to bring about the desired rotation of the window during its up and down movements. The bracket is connected to an endless chain passing around sprockets one of which can be rotated by hand to move the window. Specification 852,875 is referred to.

Title: Improvements in and relating to electric valve circuits for controlling current impulses in welding and other load circuits
IPC: B23K11/24
Filed: 1942-11-13
Abstract: 569,847. Control systems for resistance welding &c. BRITISH THOMSONHOUSTON CO.. Ltd. Nov. 13, 1942, No. 16059. Convention date, Nov. 22, 1941. [Class 38 (iv)] Thermionic and switching control.-To obtain a timed impulse of current and predetermine the current taken in a single half-cycle from an A.C. supply, a condenser 15, charged from a D.C. source 12, 13, is discharged through a valve 20, preferably gas-filled, having two control electrodes, of which one, 24, is supplied with a hold-off voltage and the other, 23, with an impulse voltage of peaked form derived from the A.C. supply and adjustable in phase. The timed current impulse may be supplied to the ignition electrode of a valve to supply a halfcycle welder through a resistance shunted transformer 3. After a time-delay relay 55, protecting the valves, has closed, the energization of a relay 18, as by a manual switch 54, opens a switch 17 to remove the hold-off voltage, whereupon the valve 20 becomes ignited at an instant in the cycle of positive anode voltage determined by the setting of a phase-adjusting resistance 40 in a circuit supplying the peaking transformer 31. As the condenser 15 becomes discharged, a condenser 35 has its charge increased to apply a bias potential to the control electrodes 23 which prevents succeeding voltage peaks from igniting the valve 20. Re-closure of the relay contact 17 restores the circuit. A space discharge tube 29 defines the hold-off potential on electrode 24.
