Filed: 1929-03-01
Abstract: 311,317. Atlantic Coast Fisheries Co., (Assignees of Taylor, H. F.). May 9, 1928, [Convention date]. Preserving fish, meat, poultry, &c.-In preserving fish, meat, poultry, and other flesh foodstuffs, they are treated with a solution of a buffer salt or of an alkali to increase their PH value to such an extent that they hold their water content firmly and exhibit a tendency to swell. The treatment is particularly adapted to materials to be cold stored. In treating fish such as haddock and cod the PH value is brought to about 7 preferably by using trisodium citrate, trisodium phosphate, sodium carbonate, sodium hydroxide, or the corresponding potassium or ammonium derivatives, preferably in aqueous solution. Sodium chloride and other material and harmless salts which by osmotic pressure will prevent the foodstuffs absorbing extraneous water may also be added. A substance which will prevent loss of colour may also be included, and may in the case of fish consist of sodium, potassium, or other suitable nitrite. Examples of solutions used are given in the Specification. Reference is made to the Public Health (Preservatives, &c., in Food) Regulations, 1925 to 1927.

Title: Improvements in devices for dimming the lamps of motor vehicles
IPC: H01C10/36
Filed: 1922-03-10
Abstract: 197,121. Duckett, G. J., and Record, J. W. March 10, 1922. Contacting solid resistances.-A dimming- device for the electric lights of motor vehicles comprises an outer cylindrical casing within which are mounted carbon plates compressed by a screw or lever against a spring or buffer, so that a continued movement in one direction makes the circuit, progressively brightens the lights, and finally shortcircuits the carbons by giving a metal to metal contact through the device. The, carbon plates E, Fig. 2, are mounted on a spindle D in a metal casing A between a screw-threaded adjusting-cage B and a metal end plate B<1>, a spring b<4> opposing the compressing action of the adjusting-cap. One terminal b is provided on the plate B', and the other terminal b<1> is on the spindle which extends through the adjusting-cap and is provided with two nuts b<5>, b<6>, the nut b<6> preventing the cap from being unscrewed too far. In the fully unscrewed position of the adjusting- cap, the carbon plates rest against an insulating washer e, thus breaking the circuit, and in the fully compressed position of the carbons, a metal to metal contact through the device is made with the nut b<5> and adjusting-cap. In any intermediate position the current passes through the carbons and the lights are dimmed accordingly. In the construction shown in Fig. 4, the metal to metal contact through the device is provided by forming a projection b<7> on the adjusting-cap which contacts with the spindle D when the carbons are short-circuited. In the construction shown in Fig. 5, the carbon plates are carried within an insulating tube d' which is positioned inside an inner casing A', one terminal being connected to this casing, and the other terminal to an outer casing A insulated from the inner casing. In the dimmed position the current passes through the spring b<4> and carbons, and when full compression is reached, the adjusting- cap electrically connects both casings. Instead of the spring b<4> a rubber pad may be employed, in which case a flexible electric connection is provided between the lowermost carbon plate and one of the terminals. The outer casing may be enclosed in an insulating cover. The carbon plates may be flat or conical, or may have roughened surfaces.
