Abstract: 307,010. Steiner, J., Hodko, F., Burnaty, K., and Pillis, A. March 1, 1928 , [Convention date]. Vaporizers, external. - A vaporizer for heavy fuel comprises a chamber d<1> surrounded bv an exhaust jacket d and containing a ring H provided on its exterior with right and left handed screw threads which cross each other so that flats H<1>, H<2> are formed at diametrically-opposite parts of the ring. The tops of the threads contact with the wall of the chamber, and the flats are situated opposite inlet and outlet tubes l, m. Heavy fuel atomized by a nozzle k together with a small quantity of air supplied by a duct y passes through the inlet l, the rich mixture passing along the flat H<2> and then around the grooves of the threads to the flat H<1> adjacent the outlet m. The main air supply enters through a gauzecovered inlet n and is deflected through a rightangle before mixing with the rich mixture issuing from the outlet m into the induction passage D<3>. The heavy fuel is supplied by a float chamber A, and is controlled by a needle valve b held open by a spring f bearing against an adjustable collar b<2> and by a manually-adjustable needle valve j<3>. Light fuel for starting is supplied through a conduit 5 controlled 'by a spring- loaded valve c, and passes through a conduit v<2> controlled by a manually-operated valve v, the outlet of the conduit v<2>, which is situated in the induction passage D<3>, being provided with a valve w carried by a suction-actuated perforated plate p. The stem c<1> of the valve c is pivoted to a grooved member s<1> connected by a spring r to a grooved member c which is pivoted to a manually-operated lever q situated above the stem b<1> of the valve b. The operation of the lever q thus closes the heavy-fuel valve b and opens the light fuel valve c.

Epoxy silicones used may have the general formula MDxUyM\svq where D represents an R2SiO unit in which R is a monovalent hydrocarbon radical free of acetylenic unsaturation; U represents an RR\sv SiO or R\sv SiO 3/2 unit in which R1 is a monovalent organic radical with at least one epoxy group, M and M\sv have the formula R\yF 3-a R\sv a SiO 1/2 where R\yF is a monovalent saturated hydrocarbon radical; y is an integer of 1 to 102, x is an integer of 10 to 105, a has a value from 0 to 1 inclusive, p has a value of 1 when U=RR\svSiO and y + 1 when U=R\sv SiO 3/2 , the molecular weight of the compound being between 103 and 106 and the ratio of epoxy-containing units to other units being between 0.001 and 0.5.  The addition product may contain 0.2 to 85% silicone and be formed from a fatty acid ester containing at least one ethylenically unsaturated bond, such as drying and semi-drying oils.  The preferred addition products have the general unit formula (R\sv3SiO) (R\sv2SiO)x (R\svHSiO)y (SiR\sv3) where R\sv is monovalent, x has a value of 0 to 60, and y has a value of 1 to 60. The paper sheet may be a multi-ply sheet containing no rosin or alum sizing compounds.  The silicone is applied preferably as an aqueous emulsion with agents such as quaternary ammonium salts, aliphatic alcohol sulphates or polyoxyethylene derivatives of polyhydric alcohols, and is cured before the paper is applied to the board, preferably before the silicone is applied to the paper.  Curing catalysts include metal salts of organic acids (Pb, Fe, Zn, Cu, Al, Mg, Cd, Co, Ni, Sn and Na salts) and a dialkyl methyl diester of an organic acid.

Title: Improvements in or relating to hydro-pneumatic suspension units for vehicles
Inventor: WORDSWORTH JACK
IPC: B60G17/044
Filed: 1958-01-07
Abstract: 869,640. Maintaining vehicle height constant; hydropneumatic springs. ARMSTRONG PATENTS CO. Ltd. Dec. 31, 1958 [Jan. 7, 1958], No. 563/58. Classes 108(2) and 108(3). A hydropneumatic suspension unit incorporates a pump to maintain a suitable working pressure. Liquid spaces A, B, on either side of a piston 6 working in a cylinder 4 are bounded respectively by flexible diaphragms 5, 26, on the other sides of which are respective compressed air spaces 7, 27. On rebound stroke of the piston 6, liquid is drawn through a valve 23 from the space A to a pump cylinder 12. On compression, this liquid is forced by pump plunger 9 through a valve 22 and passage 9c into the space B. When a predetermined vehicle height is reached, a shoulder 9b of the plunger 9 engages a ball 15 to unseat a valve 17 and thus permit liquid to escape from space B via a passage 19, valve 17, and a passage 20, to space A. Damping is provided by apertures 10c in a valve 10b. The cylinder 4 is flexibly mounted by a rubber bush 25 in the housing 2 of the unit. This enables the piston 6 and connecting rod 6a to be unitary.

Filed: 1976-01-09
Abstract: 1496752 Mowers INTERNATIONAL HARVESTER CO 9 Jan 1976 [10 April 1975] 00793/76 Heading A1F A reciprocating mower comprises an antivibrational means of attachment to a tractor. A U-shaped bail 20 is pivotally mounted at 22, 22 on the 3-point lifting gear 12, 14, 15 of a tractor 10, and it is also interconnected with a drag bar 30, and associated cutter-bar 61 and knife 66, by a leaf-spring 32 and pull-bar 40 to form a 4-bar parallel linkage having three of its vertices 36, 41, 45 allowing free pivotal movement, whilst the fourth, between spring 32 and drag bar 30 is rigid to maintain the cutter bar 61 transverse to the direction of travel. The knife 66 is driven from the tractor's extendable PTO shaft 19, via a stub shaft 87. a drive sheave 79 journalled at 77 for adjustable positioning by a J-bolt 82, a belt 86 and a sheared flywheel 73 having a pivotally attached pitman stick 75. The cutter-bar 61 is pivotable upwardly about its hinge 63, 64 to the drag bar 30 by raising the arms 12, 14, thus pulling on chain 52, rocker lever 51, and chain 50 which rotates the pull-bar 40 about its fore-aft axis, thus pivoting a link 54 and lever 55 to pull the cutter-bar up. The cutter-bar 61, the knife 66 and its drive apparatus 71-89 are vibrationally isolated from the tractor, whilst still allowing lateral oscillation of the cutter bar, which is desirable to help cleaning of the cutter-bar and to improve the mowing action in heavy or tangled crops. The pull-bar 40 is longitudinally extendable in response to overload on the cutter bar 61, which, together with the drag-bar 30, will then pivot back about the pin 36.

Abstract: 267,890. Renault, L. March 22, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Controlling different functions by same lever; pneumatic transmission ; setting devices for controlling-apparatus.-The clutch is operated by the accelerator pedal acting through a servo-motor. In the construction shown, the accelerator pedal 13 acts on the throttle 16 through a lost-motion connection 17, 18 and also operates a valve 4 controlling a vacuum cylinder 1 which effects the engagement of the clutch. When the pedal is depressed from the position shown, in which a port 4' of the valve puts the cylinder in communication with the atmosphere, the valve is moved until this port is closed to the atmosphere and open to an enginesuction pipe 8, the piston 2 being thus operated to cause the clutch to be engaged. Further movement of the pedal 13 then opens the throttle to any desired extent. In case the driver wishes to close the throttle without de-clutching a mechanical resistance is provided to let him know when the pedal is in the desired position. This resistance comprises a spring-pressed member 20 adapted to engage in a certain pedal position with a notch in the pedal shaft.
