IPC: B60P1/48
Filed: 1944-09-04
Abstract: 607,119. Road vehicles. DEMPSTER BROS., Inc. Sept. 4, 1944, No. 16860. Convention date, Oct. 1, 1943. [Class 108 (i)] [Also in Group XXX] Transporting and dumping equipment adapted for mounting on a road vehicle chassis comprises a base frame 10 and a plurality of means extending forwardly of the rear end of the frame and including a plurality of carriages 16, in side-by-side relationship for separately, and individually handling a plurality of containers and a single means 31 common to the carriages for moving the containers into and out of co-operative relationship therewith. As shown, the base frame 10 comprises channel, I or angle-section members, two pairs of which form forwardly extending means in the form of tracks for the carriages 16 which are movable thereon by the action of a hydraulic piston 28 and cylinder 29. The common means 31 comprises a boom structure having three laterally spaced arms 32 pivoted at 30 to the frame 10 and adapted to be raised by a hydraulic piston and cylinder 37 to lift either one or both of a pair of containers 42, Fig. 7, supported from their outer ends into engagement with skidways 20 associated with the carriages 16. On release of pressure in the respective cylinder 28, the carriage 16 moves forwardly under the weight of the container 42 which slides down inclined supporting plates 38 to the position of the container 42<SP>1</SP> in Fig. 7. During transportation the boom is lowered so that its arms 32 provide a lateral support for the containers which may be of any suitable construction, cylindrical or rectangular and may be of the kind described in Specification 547,680. The free end of the boom members 32 may be provided with two sets of chains, one short for attaching to the bail of a bailsupported container and one long for use with a bottom dump or other type of container. The skid frames 20 may be provided with antifriction means such as rollers but preferably these are mounted on the forward faces of the containers. A single container of width equal to the full width of the frame 10 may be handled simultaneously by both carriages 16 by removal of the intermediate of the three boom members 32. The skid-way 20 may be provided with an automatic bail-engaging dumping- hook 24, Fig. 1, as described in Specifications 507,079 and 605,864, [both in Group XXX]. Specification 547,537, which describes an arrangement of containers mounted in fore- and-aft tandem relationship on a vehicle, also is referred to.

Abstract: 835,307. Automatic volume control. BRITISH BROADCASTING CORPORATION. May 28, 1958 [May 28, 1957], No. 16973/57. Class 40 (4). A signal is applied across one diagonal and is taken from across the other diagonal of a bridge R the balance of which is controlled by a bridge M of non-linear resistors one diagonal of which shunts an arm of bridge R and the other diagonal of which is subject to a control signal. Use of the bridge M prevents the control signal appearing in the bridge R and prevents voltage fed back from the bridge R altering the impedance shunt. The output from bridge R is applied between the high-resistance cathode and grid connections of amplifier V.

IPC: D21C9/10
Filed: 1921-06-21
Abstract: 179,885. Steinhilber, H. May 13, 1921, [Convention date]. Pulp, preparation of.-In a process for the production of cellulose from reeds and similar lignified plants, including papyrus, without the employment of chemicals, the materials, cut into small pieces, and preferably after steaming, are passed between crushing-rollers or treated in edge rollers or other suitable machines to deform the parenchym cells, which may, if desired, be removed by washing with water.

Title: Hydrocarbon separation process
Inventor: FEATHERSTONE WILLIAM
IPC: C07C7/152
Filed: 1963-05-01
Abstract: Olefinic and aromatic hydrocarbons are extracted from liquid or gaseous diene-containing hydrocarbon mixtures by treating to remove substantially all the dienes and subsequently contacting the mixture with an aqueous solution of silver nitrate, fluoborate, or fluosilicate whereby the olefinic and aromatic hydrocarbons are removed as complexes, from which they may be recovered for example by contacting the aqueous solution with a paraffin.

Title: Improvements in or relating to pitch control for helicopter rotors
IPC: B64C27/54
Filed: 1947-07-02
Abstract: 635,017. Helicopters. DOMAN-FRASIER HELICOPTERS, Inc. July 2, 1947, No. 17440. Convention date, July 18, 1946. [Class 4] The pitch changing mechanism of a helicopter rotor is connected to a gyroscopic control member mounted on a vertical axis and incorporating liquid or friction dampers rendering the control member fully responsive to long term changes of fuselage attitude, but insensitive to short term changes, such as pendular oscillations of the fuselage. In the form shown the gyroscopic control member consists of the engine cooling fan 35 mounted on a vertical shaft 36 by a homokinetic universal joint 37, and connected to the piston rods of two hydraulic cylinders 30, 32 disposed perpendicular to each other. These cylinders are connected by pipe lines 23, 24 and 25, 26 to a second pair of cylinders 20, 21, the piston rods 17, 22 of which are connected to the azimuth control plate 16 at points spaced 90 degrees apart. The fan 35 is connected to the vertical shaft 36 by dashpots 38, 39 having light damping characteristics, whereby the fan 35 remains substantially horizontal when the fuselage executes pendular oscillations, but changes its plane of rotation into one perpendicular to the shaft 36 in response to gradual changes of attitude. The hydraulic connections ensure that the azimuth control plate 16 remains parallel to the gyroscopic member 35. Instead of dashpots, frictional dampers may be employed, and in either case the degree of damping may be adjustable. Manual control of the azimuth plate 16 may be effected by a pair of hand levers 46, 52, or a single universally mounted lever, connected to hydraulic pistons and cylinders 49, 54 in communication with the cylinders 19, 21 by pipelines 50, 51 and 56, 57 respectively, the latter being fitted with equalizing valves 58.

Coenzyme A is obtained by inoculating a hydrocarbon-assimilating micro-organism which belongs to one of the genera: Corynebacterium, Brewibacterium, Psevdwmonas and Arthrobacter on to a culture medium comprising a carbon source mainly consisting of hydrocarbons containing not less than 10% (volume/volume) of normal paraffins having a carbon atom number within the range of from 9 to 23 and other nutrients required for the growth of the microorganism, incubating the culture medium under aerobic conditions until coenzyme A is substantially accumulated in the culture broth and recovering the coenzyme A. Specified microorganisms are Corynebacterium hydrocarboclastus, Corynebacterium fascians, Brevibacterium alkanol yticum nov. sp., Brevibacterium alkanophilum nov. sp., Brevibacterium leucinophagum, Pseudomonas alkanolytica nov. sp., Pseudomonas aeruginosa and Arthrobacter simplex and the characteristics of the specified novel species which are isolated from soil are described. The incubation is preferably carried out in a liquid culture medium at a pH of about 5À0 to 9À0 and at about 20 to 40 C. The hydrocarbon present may comprise one or more C 9 -C 23  normal paraffins and other hydrocarbons, e.g. branched paraffins, olefins, cyclic paraffins, aromatic hydrocarbons or C 1 -C 8  normal paraffins, and other carbon sources such as carbohydrates may also be present. The culture medium should also contain a nitrogen source and may also contain pantothenic acid or its salts, a small quantity of inorganic salts, and a surfactant. The accumulated coenzyme A may be recovered by extracting the cells with hot water, and treating the extract and/or cleaned broth with activated charcoal and/or anion exchange resin.
