Abstract: 344,730. Liquid level indicators. GUY, B. A., 41, Avenue Verdier, Montrouge, Seine, France. May 28, 1930, No. 16502. Convention date, July 30, 1929. Addition to 271,875, [Class 123 (i), Liquid-level regulating &c.]. [Class 123 (i).] In the liquid level indicator described in the parent Specification means are provided whereby the indications are not affected by variations in temperature due only to variations in pressure. A tube 1, connected to the boiler, is provided with closed tubes 4 in the walls, each having an insulated rod 5a forming a temperature-variable resistance which is connected in the primary circuit of a transformer t supplied from mains 11, 12. The secondary circuit of the transformer includes a lamp 8, and variations in the primary current due to variations in resistance of the tube 4 and rod 5a according as the tube 4 is below or above the water level cause corresponding variations in the illumination of the lamp 8. A resistance 9, Fig. 2, is included in another primary circuit of the transformer, which is in opposition to the circuit 5. The lamp 8 is illuminated when the tube 4 is in contact with water, which causes a decrease in its resistance and an increase in current through the primary circuit 5. The resistances,9 9 are arranged near the tube 1 so that they are subject only to the mean temperature of the gauge and thus to the temperature dependent upon the boiler pressure, but not upon the water level, so that the indications given by the lamp 8 depend only upon water-level. A number of modifications are described.

Title: Means for minimising fire risks on motor vehicles
IPC: H01M50/574
Filed: 1932-06-13
Abstract: 403,087. Inertia switches. LUCAS, Ltd., J., and LUCAS, 0., Great King Street, Birmingham. June 13, 1932, No. 16651. [Class 38 (v).] To minimize fire risks on motor vehicles, the battery a is mounted so as to slide forward against a spring d in the event of a collision and break circuit beween two terminalsf,g. The spring d is strong enough to prevent movement of the battery during normal retardations. In the form shown in Fig. 1, the terminals f, g are normally connected by a bridging member h with a lip j overhanging the terminal f. When the collision occurs, the terminal g moves to the right with the battery and a spring i pulls away the member h. When the battery returns under the action of the spring d the contacts f, g do not touch and the circuit remains broken. In a modification, Fig. 9 circuit is normally completed between two conducting strips p, r backed by insulation q, s. Upon collision the strip p, q moves to the right and on the return movement slides above the strip r, s so that the insulating portions now touch and the circuit remains broken. In another modification a spring-pressed insulating rod comes between the terminals f, g on collision, and in another a wire joining the terminals f, g snaps allowing an insulating tube to fall and keep the terminals separated.

Patent GB-412768-A (GB)
Title: Improvements in or relating to the production of seamless hollow rubber articles such as play balls
Filed: 1933-06-16
Abstract: Seamless hollow closed rubber articles such as balls, are produced by solidifying latex or like dispersions by internal or external moulding on a solidified aqueous solution of a hydrophilic colloid, such as gelatine, agar agar, starch, starch acetate, gum tragacanth, algin, Iceland moss or pectin, and which may contain a small quantity of coagulant.  The jelly can be cast in a spherical mould to form a sphere which can be immersed in latex.  The jelly can be removed from the rubber casing by warming so that it can escape through a small aperture in the casing, and this warming may also effect part of the vulcanization.  Or the jelly may be cast in hollow spherical moulds which while the jelly is solidifying are subjected to rotation about a variable axis, the latex is then introduced to the inside of the jelly mould and the closed moulds again rotated about a variable axis until solidification of the latex.  The balls are removed, jelly scraped off, then replaced in the moulds and vulcanized in boiling water or superheated steam.  The balls may be inflated by introducing a capsule containing a gas generating composition, or by introducing gas through a one way valve on the mould or through an inflating needle or by producing the ball without inflation, subsequently storing it in compressed gas and finally coating it with rubber solution.  A gas retaining lining, such as a gelatine-glycerine mixture, may be introduced by a needle.  Specifications 219,635, 285,938, 290,313, [all in Class 70], and 391,853 are referred to.
