Title: Improvements in or relating to liquid fuels for internal combustion engines
IPC: F02B47/00
Filed: 1934-01-26
Abstract: Liquid fuel for Diesel and like engines is primed by dissolving therein one or more organic peroxides or mixtures containing such oxides, or by forming such oxides therein, no other primer being present.  Fuels specified are gas oil, heavy pressure distillates, Edeleanu extract of kerosene, coal tar fractions, and vegetable oils. Suitable peroxides are obtained by passing air or oxygen, maybe in presence of catalysts, through hydrocarbons such as vapourphase cracked benzines.  In examples, 0,5, 1,0, and 1,5 per cent of tetrahydronaphthalene peroxide are added to gas oil, and 5,0 per cent to Edeleanu extract of kerosene. Specifications 294,129, [Class 91], and 354,398 are referred to.

Abstract: 163,094. Enrich, F. S., and Serrano, C. P. Feb. 4, 1920. Cut-out systems.-Overhead conductors are protected by an electromagnetic cut-out arrangement comprising two electromagnets F, F<1>, Fig. 1, acting in opposition upon a movable armature G which carries a contact N adapted to complete, the circuit of the actuating-coils A of an electromagnetic switch B. One of the electromagnets F is connected between the guard wire P and an earth T; the other electromagnet F<1> is in an earthed branch off the main supply A<11> through a resistance L. The electromagnetic switch B, when no current flows through the actuating coils A, bridges over contacts D, D<1> in the connection from the main supply to the overhead conductor P<1>; when the coils A are excited, they raise the bridging contact and cut off the supply to the contactor P<1>. In action, the armature G is held up in the position shown by the combined effect of the upper magnet and a spring M against the effect of the lower magnet. If a breakage occurs with consequent loss of energy in the guard wire, the upper magnet becomes dead and the lower magnet, which is not affected, pulls the contact N into position for bridging stationary contacts I, I<1> and so exciting the coils A. A lamp or other signal O<1> is simultaneously set in action bv the closure of a pair of contacts K, K<1>. In order to re-set the apparatus, a switch L' is opened by hand, thus cutting out the magnet F<1>. The arrangement may be modified for three-phase lines by providing three electromagnets corresponding to A and controlled by three contacts on an armature corresponding to G.

[Class 40 (ii).] A light-valve suitable for the photographic recording of sound in which a vibratory tensioned ribbon supported by bridge members is arranged in a magnetic field so as to modulate passing through a light-transmitting aperture has provision for adjustment of one or both of the bridge members. The light-valve consists of a casing 1, Fig. 1, containing an electromagnet to the core 5 of.which is secured a polepiece 6 while on a cover 2 secured to the casing 1 is mounted a polepiece 7 and a ribbon suspension means. One end of a vibratory ribbon 10 is secured to a take-up screw 11, as shown by an inverted plan view of the interior of the casing cover, Fig. 3, from whence it is drawn across the polepiece 7, over a light-transmitting aperture 12, around an idler pulley 13 and back over the polepiece 7 to a take-up screw 14. The take-up screws 11, 14 are mounted on blocks 15, 17, respectively, to which are secured conductors 18, 19 terminating in binding posts on the outside of the cover 2, so that sound modulated current may be supplied to the ribbon 10 through these binding posts. The pulley 13 is mounted in a spring suspension device 22 adjustable from the front of the cover to regulate the tension on the ribbon 10. The adjusting means for the ribbon 10 consists of bridge-blocks 24, shown in the inverted perspective view, Fig. 2, one of which is provided at each of the suspension points on opposite sides of the polepiece 7. Each of these blocks 24 is secured to the cover 2 and is provided with a projection 25 which is made relatively flexible by a saw cut 27. This projection 25 is adjustable by a micrometer screw 29 threaded in the projection 26. On the projection 25 is secured a non-conducting strip 30 of ivory in which is mounted a pin 31 so that the ribbon may rest on the ivory strip and against the pin 31. By means of the screws 29 adjustment of the two portions of the ribbon in relation to each other, and to the aperture 12, may be effected. Specification 344,524 is referred to.
