Title: Improvements in or relating to trolley systems
IPC: B60L5/16
Filed: 1939-08-02
Abstract: 520,720. Current collectors for electric vehicles. ACIERIES DE GENNEVILLIERS. Aug. 2, 1939, No. 22425. Convention date, Aug. 5, 1938. [Class 104 (iii)] A trolley pole is pressed upwards by compressed air admitted to a cylinder 6 sliding on a fixed piston 5, the pole being connected to the cylinder by rods 7 which are more or less vertical so that the pressure of the collector remains constant irrespective of the angle of the pole. The air is admitted to the cylinder by a three-way valve 9, pipe 8, slide valve 13 and a spigot 2 in the piston 5. The valve 13 is normally forced to cut-off position by a spring 14 so that the cylinder is exhausted through port 15. It is restored to admission position shown by air admitted to the valve chamber by one or more press valves 18, 18<SP>1</SP>. If the collector is dewired, the cylinder 6 rises until ports 21 clear the piston 5 and exhaust the air, so that the pole descends by gravity. Its rise is checked by a dashpot 22. In another form, a valve closing ports in the top of the' cylinder is automatically opened to exhaust the cylinder when the pole rises excessively. Means are provided for centring the pole symmetrically to the axis of the vehicle when in lowered position.

Title: Polymerisation

Filed: 1972-05-12
Abstract: 1357492 Controlling chloroprene polymerization E I DU PONT DE NEMOURS & CO 12 May 1972 [12 May 1971] 22487/72 Heading C3P The Specification describes and claims, in considerable detail, a process for controlling the aqueous emulsion polymerization of chloroprene by repeatedly monitoring both the reaction temperature and specific gravity of the reaction medium. The reaction temperature is maintained within a predetermined range, e.g. 37-41‹ C., with heating or cooling as necessary in response to the measured temperature, the rate of introduction of catalyst being reduced or stopped if the temperature goes outside the desired range and being restored when the desired temperature is re-attained. The specific gravity measurement, e.g. by a gamma radiation gauge, is used to control the addition of catalyst with a view to maintaining a substantially constant rate of polymerization. The process control is suitably effected automatically, e.g. by computer.

Title: Pretreatment of iron and steel base for single coat vitreous enamelling
IPC: C23D3/00
Filed: 1958-07-16
Abstract: An iron or steel base is prepared for enamelling with a single coat of a light-coloured vitreous enamel by coating the base with one or more of titanium dioxide, antimony oxide, tungsten oxide or molybdenum oxide or with a mixture of molybdenum oxide with nickel oxide and/or cobalt oxide, and then heating it in a neutral or reducing atmosphere so as to reduce the oxide to the metal. The oxide coating may be applied as such e.g. as a suspension or dispersion in water or other liquid such as glycerine or a light oil, if necessary adding a dispersing or suspending agent such as starch or a surface-active agent to the medium.  Alternatively, the oxide may be formed in situ by applying to the base a solution or suspension of a compound which can be decomposed to yield the oxide, e.g. ammonium molybdate, molybdic acid, ammonium tungstate, sodium tungstate, tungstic acid, and nickel nitrate or chloride.  The oxide-coated base is heated to 1150 DEG -2000 DEG F. to form the metal, after which the product may be lightly pickled and provided with a nickel strike before being enamelled.
