Title: Improvements in and relating to the operation of electric luminous gas-filled and/orvapour-filled tubes and/or lamps
IPC: H05B41/24
Filed: 1934-03-21
Abstract: 435,931. Changing signs. FODOR, J., Mount Park, Harrow-on-the-Hill, Middlesex, and NORTH, V. B., Boldshaves, Woodchurch, near Ashford, Kent. March 21, 1934, No. 8883. [Classes 3 (i) and 3 (ii)] [See also Groups XXXV and XL] High-frequency current is supplied to more than two strip electrodes a ... f, running longitudinally and/ or transversely across a panel support 3 on or in which they are mounted or embedded so that gas filled discharge lamps may be attached to various parts of the panel and operated without direct connection to the electrodes. The electrodes produce electrostatic fields in " strips " having selected intensity so that tubes may be mounted thereon according to the luminous effect desired. The electrodes may be connected to tappings on a h.f. supply transformer 1, 2 and may be spaced at unequal distances from each other. The tapping points are adjustable manually or automatically according to the varying luminous effect desired. They may be supplied in series with variable capacity, inductance or resistance and may be connected and arranged as shown on electrodes g, h, and c, d, Fig. 7, to produce an intense field over a short length of a lamp so as to facilitate starting of the discharge. An arrangement is shown in Fig. 5 which allows of tubes of various sizes being operated from the same supply source. The connections to the starting and running electrodes may be controlled by a manually operated barrel switch 5, Fig. 7. In one arrangement, Fig. 8, pairs of vertical electrodes 6, 7 are arranged behind each of separate letter-shaped tubes and one electrode 6 of each pair is arranged to be oscillated mechanically by a cam 10 so as to vary the lighting effect. Alternatively one electrode of each pair is connected to the supply through a contact type or a capacity type selector switch. In a further modification, separate discharge lamps are mounted on sub-panels which may be attached to the main panel support carrying the electrodes. In one arrangement, Fig. 11, the panel is provided with electrodes a, b, c connected to the supply and electrodes j, k .... o, connected to contacts on a drum switch 14 so that a large flat discharge vessel may be mounted on the panel and variable luminous effects produced therein.

Title: Overspeed Brake
IPC: F16D51/02
Filed: 1969-02-20
Abstract: 1,189,964. Turbine stop gear; engine stop gear. GENERAL MOTORS CORP. Feb.20, 1969 [May 20, 1968], No.9233/69. Headings F1K and F1T . The invention relates to an engine overspeed brake which comprises a braking ring which rotates in close proximity to a fixed brake drum, the braking ring being of non-uniform form so that upon excessive speed the ring is deformed and parts engage the brake drum to retard the engine, there being further means including cam members which act to increase the force with which the deformed parts of the braking ring engage against the brake drum. The invention is described with reference to a turbine which comprises a bladed rotor 10 mounted on a shaft 13, the rotor disc being formed with an annular flange 17 which is shaped to form two diametrically opposed cam members 18. A braking ring 21 is mounted on the flange to rotate therewith, rotation being in an anti-clockwise direction as seen in Fig.2. The braking ring 21 has a cylindrical outer surface which rotates in close proximity to the cylindrical inner surface of a stationary brake drum 22 which is integral with stator structure. The braking ring is so formed as to provide two diametrically opposite portions 25 of increased mass so that in the event of rotor speed increasing above normal speed the weighted portions 25 expand under centrifugal loading and engage against the inner surface of the brake drum 22 as shown in Fig. 3 so acting to retard the rotor. As the braking ring is retarded, the rotor and flange portion 17 tend to continue to rotate so that the cam portions 18 of the flange portion tend to move towards the enlarged portions 25 of the braking ring 26 so increasing the braking effect. The internal surface of the braking ring 26 is recessed in the region of the enlarged portions 25 and weights 28 inserted therein so as to increase the centrifugal effect.

Abstract: 511,612. Drying clothes &c. LISTER, V., and BROAD, L. F. March 28, 1938, No. 9509. [Class 34 (ii)] In a laundry drying machine comprising a perforated rotary drum 5 for containing the clothes housed in a drum chamber 2 above an air heating chamber 3 from which heated air is admitted axially into the drum through an opening 19, the fan 14 for circulating the air is located inside the drum chamber to facilitate the re-circulation of part of the heated air which has passed through the drum. The remaining moist air enters the atmosphere through an outlet 8. The fan is arranged within the opening 19, which are both of the same diameter, and is mounted in a bearing 16 carried by the rear wall of the drum chamber. The fan drive also serves to drive the shafts 18 of rollers 9 on which the drum is mounted. The heating chamber 3 contains a heater 6, over which flows fresh air from a screened opening 13, and communicates with a rear duct 4 having angularly disposed side walls 7x converging from the base of the duct, which extends the full width of the heating chamber, to the fan opening. Part of the moist air may be re-heated before re-circulation through the drum by withdrawal through an opening 23 directly into the heating chamber, the opening 23 being provided with an adjustable closure 24. Curved screens 25, 26 are disposed below the outlet 8 and above the aperture 23, respectively, to trap lint &c. which is removed on accumulation by a brush 27 secured to the periphery of the drum. The brush is carried by an adjustable leaf spring. Lifting blades within the drum effect movement of the clothes across the current of heated air.
