Abstract: 648,277. Aerials. RADIO CORPORATION OF AMERICA. Sept. 23, 1947, No. 25858. Convention date, Feb. 28, 1946. [Class 40 (vii)] A broad-band antenna system comprises a number of elongated narrow slots in a conductive. sheet, the slots being arranged in a regular geometric pattern with a conductive walled cavity behind each slot, and a transmission line system from a source of energy being connected to energize the slots in the correct phase relationship to produce a uniform radiation pattern. In Fig. 10, a delta formation of three slots is provided in the conduction skin of an aircraft and is energized in 120 degree phase relationship by coaxial lines 70, 71 and 72, 73 extending from a connector TLC through each of the quarter-wavelengthdeep cavities 60, 62, 64 backing the slots. The electrical length of time between each slot is made 120 degrees, and the impedance presented by each cavity together with the impedance of the coaxial lines is selected to provide a match throughout the system (see Fig. 7, not shown). An adjustable coaxial stud tuning section 75 terminates the coaxial line inner conductor in the cavity 62 and a fixed stub 84 terminates the inner conductor in cavity 60. An alternative arrangement for energizing the slots, Fig. 8 (not shown), employs a branch line to each cavity, the electrical lengths of the branch lines differing from each other by 120 degrees. The impedance presented by a slot is adjustable by selecting the height above the base of the cavity at which the coaxial line connects with the cavity, Figs. 2 and 3 (not shown). The minimum length for a slot is one-half wavelength while the slot width is <SP>1</SP>/ 20  or <SP>1</SP>/ 30  of a wavelength. In the plane of the array of slots the polarization is linear but rotates at the carrier frequency. In the direction normal to the plane the polarization is circular, while in intermediate directions the polarization is elliptical.

Title: Improvements in and relating to the construction and regulation of electric arcs
IPC: F27D11/08
Filed: 1920-09-10
Abstract: 170,738. Schlegell, F. von. Sept. 10, 1920. Furnace details.-In a device for heating by electric arcs, one or more of the electrodes are so mounted as to move under the influence of the magnetic fields set up by the current flowing through the electrodes to vary the distance between the electrodes. In the three-phase furnace shown, the electrodes are carried on a vertically adjusted counterweighted frame 4 provided with an insulating-plate 7. A central stationary electrode 8 is provided and three outer electrodes 9, each electrode 9 being carried by a clamp 11 having a knife-edge 12 by which the electrode is supported on the plate 7. An adjustable weight 14 is secured to the clamp 11, thus causing the electrode 9 to swing into the dottedline position with its lower end engaging the central electrode 8. When the current begins to flow, the magnetic fields surrounding the electrodes repel each other and force the electrodes apart, establishing an arc at the lower end of the electrodes and automatically adjusting the length of arc as the current varies. The device is stated to be applicable also in the heating of ladles.

Title: Improvements in or relating to devices for selectively controlling the braking of vehicle axles
IPC: B60T8/18
Filed: 1965-06-21
Abstract: 1,070,482. Fluid-pressure brakes. SOC. ANON. ANDRE CITROEN. June 21, 1965 [June 24, 1964], No. 26088/65. Heading F2F. In an hydraulic system of the kind, e.g. as described in Specification 796,071, including a distributer valve whose operation is modified according to the load on the rear axle of a vehicle to selectively control the distribution of fluid, supplied by a reservoir, between brake cylinders of internal shoe drum brakes associated with the wheels of the front and rear axles, at least the front wheel brakes have separate cylinders 1a 4a whose pistons 1, 4 independently operate the trailing and leading shoes 3, 5, respectively, the branch line 7 to the rear wheel brake cylinders 6 is connected also by line 9 to the front wheel brake cylinders 4a, and the cylinders 1a of the front wheel brakes are connected to the branch line 8 from the distributer. The distributer, as in the prior Specification referred to above, consists of two sections fed by inlet lines 50 and having return connections 53. The valves controlling the pressures in the branch lines 7, 8 are controlled by a pedal 23 which acts via a roller 25 on a lever 20 interconnecting the valve stems, the roller being adjusted automatically along the lever by a connection comprising levers 32, 34, link 27, cable 40 which is tensioned by spring 41, bell-crank 36 and spring 39 to the rear axle, so that it provides a variable fulcrum according to the load on the rear axle. More progressive braking is said to result from the use of separate cylinders 1a, 4a, since under lightly loaded conditions of the rear axle high pressure obtaining in branch line 8 is supplied only to cylinders 1a which operate the trailing shoes of the front wheel brakes, while the leading shoes of the front wheel brakes are applied only lightly since the pressure in branch line 7 is relatively low. In the modification of Fig. 2 (not shown) the piston 4 is of smaller diameter than piston 1, so enhancing this effect. The rear wheel brake cylinders 6 may also be replaced by double cylinders corresponding to the cylinders 1a 4a, in which case all the cylinders operating trailing shoes are connected to branch line 8 and all the cylinders operating leading shoes to branch line 7.
