Filed: 1970-07-16
Abstract: 1301005 Suspension fertilizers; bentonite and attapulgite sols STANDARD OIL CO 16 July 1970 [24 July 1969] 34471/70 Headings C1A and C1B A fertilizer comprises an aqueous suspension which includes at least 30% by weight plant nutrient (e.g. compounds of nitrogen, phosphorus and potassium and small amounts of compounds of iron, magnesium, manganese, nickel, zinc, &c.) and enough attapulgite or bentonite clay in the form of a sol to substantially inhibit settling out of solids from the suspension, which clay sol comprises from 5 to 30 weight per cent clay, based on total sol weight, and from 1 to 5 weight per cent (based on clay weight) of a condensed phosphate, e.g. lithium, sodium or potassium tripolyphosphates, tetrapotassium pyrophosphate, mixtures of ammonium polyphosphates, tetrasodium or tetralithium pyrophosphate. A method of producing such a fertilizer comprises blending plant nutrient, clay, condensed phosphate and water together to form a suspension. An improvement in such a method involves entraining an inert gas in the suspension to buoy up solids which tend to settle. A suitable gas is air and 3 to 10 volume per cent air may be entrained in the suspension.

Abstract: 994,224. Rollers. J. M. HAUSMAN. Sept. 11, 1962 [April 17, 1962], No. 34655/62. Heading F2U. [Also in Division G3] The crown of a metal roller 2 used to roll-out a strip of plastic &c. material is expanded in size to obtain uniform strip thickness by pumping-in fluid under pressure to its hollow centre 3, a motor and pump assembly 7 producing the fluid pressure being carried in or on the roller. As shown, the fluid is pumped into an expanding bag 4 in the hollow centre 3 of the roller, but alternatively the fluid may be pumped directly into the hollow roller centre, Fig. 3 (not shown). Feelers (not further described) sensing and comparing the thickness of the edge and the centre of the rolled strip control the motor pump 7, to increase the fluid pressure and expand the crown of the roller so long as the centre of the strip is thicker than the edge, Fig. 2 (not shown) (see Division G3).

[Also in Group XXXVI] In apparatus wherein a capacitive probe 11 Fig. 1, controls an R.F. oscillator in accordance with the level 18 of fluid in a container 12, the oscillator is contained in a housing 10 mounted inside the container 12. The apparatus 14 for controlling the admission of fluid to the container is connected by a cable 22 carrying only low-frequency currents. As shown, Fig. 2, the valve 26 oscillates when the capacity 52 between the probe and the container falls below a certain value, as determined by the parameters of the bridge circuit comprising the tapped inductance 38 and condensers 51, 54, i.e. when the level is correspondingly low. The anodecathode current in valve 26 which is controlled by rectified grid current thus falls, to release the anode relay 72 thereby closing contacts 86 for energizing the pump 16. Failure of the valve also causes pump 16 to operate so that the container cannot be emptied. Specification 773,982 is referred to.

Title: Improvements in or relating to the waterproofing of leather
IPC: C14C11/00
Filed: 1929-11-22
Abstract: A product used for waterproofing leather is obtained by dissolving vegetable latex, particularly that obtained from species of euphorbia and cactaceous plants, in a solvent which is then evaporated in vacuum.  The terpenes in the product may be polymerized and hydrogenated by catalytic processes.  In practice, latex from various varieties of euphorbia, for example, candelabra euphorbia and euphorbia resinifera is used.  The latex may be treated by washing with water, and may then be subjected to catalytic action by using oxidizing hydrogenating or polymerizing catalysts such as organic or inorganic salts of manganese, cerium or nickel, or diastases or enzymes.  The action of the catalysts may be aided by ultra violet rays, X-rays or other radiation.  The latex is then treated with a solvent such as tetrachlorethane or carbon tetrachloride.  Solution is effected at 15 DEG  to 20 DEG  C., and the lowest layer of liquid is separated and filtered.  After filtration the solution is evaporated in vacuum until a transparent viscous mass remains.  The polymerization of the terpenes and other constituents of the latex may be effected by heating to about 150 DEG  C., preferably in vacuum, with acetic acid, acetic anhydride, or formic acid, preferably in presence of small proportions of sulphur or sulphuric acid.  Catalysts such as boron fluoride, barium oxide, potassium cyanide or trioxymethylene may also be used.  The terpenes may also be subjected to the action of anhydrous metallic chlorides, particularly zinc chloride.  Hydrogenation may be effected by a hydrogenating process using catalysts such as metallic nickel derived from its oxides or salts by reduction.ALSO:A product used for waterproofing leather is obtained by dissolving vegetable latex, particularly that obtained from species of euphorbia and cactaceous plants, in a solvent which is then evaporated in vacuum.

Title: Improvements in or relating to Power Actuated Wave-Guide Switches.
Inventor: LEEMING JOHN ROBERT
IPC: H01P1/12
Filed: 1966-08-10
Abstract: 1,171,923. Waveguide switches. MARCONI INSTRUMENTS Ltd. 23 May, 1967 [10 Aug., 1966], No. 35889/66. Heading H1W. The rotor of a waveguide switch is actuated by an electric motor through a reduction gearing and an inverse self-locking Geneva mechanism. As described, the actuating mechanism is applied to a known kind of switch comprising an internal rotor having two passages which connect in pairs four radial waveguide ports in an external stator, a rotation of 90 degrees serving to commute the connected ports. The rotor is mounted on the same axis as the driven plate 12 of a Geneva mechanism, the driving member of which consists of an arm 10 rotating about a shaft 11. The arm 10 carries a roller 9 which engages in turn each of the four grooves 13 in the driven plate whereby a 360 degrees rotation of the arm produces a 90 degrees rotation of the plate. The switch is constructed so that connections are made when the roller 9 is in the central space 14 between one groove 13 and the next and the locking arc 20 is engaged with one of the locking sectors 19 of the plate. A cam 15, driven by the electric motor at half the speed of the arm 10, actuates a switch 16 whenever the arm reaches such a switching position, the effect of the switch 16 being to open a power circuit and to close a short circuit connected in parallel to the terminals of the motor 6. Thus the rotor is brought rapidly to rest in the switching position. A further switch 7 reverses the effect of the switch 16 and re-starts the motor.
