Title: Improvements in interpolymers
Filed: 1944-08-30
Abstract: Terpolymers are produced by interpolymerizing a diallyl ether of formula CH2 = C(R)-CH2-O-CH2-C(R) = CH2 where R is hydrogen or a methyl group, an ester of an ethylenic alpha, beta-dicarboxylic acid of formula ROOC-CH = CH-COOR1 where R and R1 may be alike or different and stand for a saturated alkyl group having from one to eight carbon atoms, a cycloaliphatic group, an aryl group or an aralkyl group, or R1 may be hydrogen, and at least one saturated monohydric alcohol ester of an acrylic acid.  The acrylic esters have the formula CH2 = C(R1)-COOR where R1 is hydrogen or a methyl or ethyl group and R is a saturated alkyl group having from one to eight carbon atoms, a cycloaliphatic group, an aryl group or an aralkyl group.  The interpolymerization may be carried out by the emulsion process or by the oil-phase process. Specified emulsifying agents are fatty acid soaps, Aerosol, "Emulphor" (Registered Trade Mark) and Turkey Red Oil. Preferred proportions are 30-70 per cent alkyl alkacrylate, 10-50 per cent diallyl ether and 10-20 per cent ethylenic alpha, beta-dicarboxylic acid.  Softening agents, e.g. dibutyl phthalate, tricresyl phosphate, ricinoleic acid esters, chlorinated diphenyl and triacetin, and fillers may be added before or after polymerization.  Specified reactants are diallyl ether, dimethallyl ether, diethyl fumarate, n-butyl acid maleate and methyl methacrylate.  The preferred polymerization temperature is from 50 to 75 DEG  C.  Catalysts such as hydrogen peroxide, percarbonates, perborates, persulphates, peracetic acid, acetyl peroxide, benzoyl peroxide, benzoyl acetyl peroxide, lauryl peroxide and succinyl peroxide may be used; a mixture of potassium persulphate and hydrogen peroxide is preferred.  The terpolymers may be made infusible and insoluble by further catalytic polymerization.  In examples: (1), (2), (3) and (6) methyl methacrylate, diethyl fumarate and diallyl ether are emulsified with water and Acrosol and polymerized using a mixture of potassium persulphate and hydrogen peroxide.

Abstract: 953,202. Haymaking machines. C. VAN DER LELY N.V. May 10, 1960 [June 5, 1959], No. 16487/60. Heading A1F. Relates to a haymaking machine of the kind comprising a frame 1 supported on ground-wheels 33, 34 and carrying a tined body 2, 3 rotatable about a horizontal axis to work the crop as the frame is towed by a tractor 8. According to the invention, the tined body is positively driven and its axis of rotation is located in the same vertical plane as those of the groundwheels 33, 34, the wheels being connected to levers 39 coupled to a torsion rod 50 extending parallel to the axis of rotation of the body in such a way that vertical movements of the wheels subject the torsion rod to a stress which resiliently opposes these movements. The main frame is U-shaped, the rearwardly-extending limbs 5, 6, carrying stub-axles 7 which support the tine-carrying shaft 2. Brackets 40A on the limbs 5, 6 have horizontal pivots 40 for the levers 39, one end of each lever being coupled to an arm 49 rigid with the torsion rod and the other carrying a vertical bearing in which the cranked axle 35, 36 of each ground-wheel is journalled, each bearing having a locking sector 42 which co-operates with a locking member 41 on the axle to fix the rotationplane of the wheel. A hand-lever 55 secured to the centre of the torsion-bar cooperates with a fixed detent on the frame 1 to apply torsion at will to the bar 50 to raise and lower the rotor. The draw-bar 59 is V-shaped, one leg 61 being telescopic and both legs being pivoted to brackets on the frame. The shaft 2 is rotated by a belt 14 passing around vertically-spaced pulleys 16 and around a pulley 11 driven by a telescopic shaft 9 connected to the tractor power take-off. The pulley 11 is laterally slidable on guides 19 and the belt 14 is tensioned by a toggle-lever 31 connected to the pulley-mounting (Fig. 5, not shown). The shaft 2 is of square-section the tines 71, 72 (Fig. 6) being mounted in pairs with the aid of clamps 77, 78. In a modification (Fig. 7) for a circular shaft 81, partly-spiral members 82, 83 are clamped in pairs by bolts 84 and have channels which accommodate the inner ends of the tines, 79, 80. In a further construction (Fig. 9), the body includes strips 87 through which the ends of the tines 3 pass, the strips being supported by curved spokes 89 whose outer ends 90 are bent over around the strips. Specification 953,203 is referred to.

Abstract: 1494590 Automatic control of fuel injection in IC engines FORD MOTOR CO Ltd 23 April 1976 [27 May 1975] 16542/76 Heading G3N A fuel injection system provides a gradually increasing quantity of fuel during the cranking period before the engine starts, as shown in Fig. 2, in addition to the normally computed quantity of fuel. In the arrangement shown in Fig. 1, timing pulses derived from the ignition circuit as well as an enabling reference pulse operate through gating network 16 to cause monostable multi-vibrator 20 to be triggered each time a timing pulse is received. The staircase generator integrates these pulses to produce the step rising output 160 shown in Fig. 2 and the discretely increasing signal is added to the main fuel injection control signal. A comparator 32 is used to compare a voltage proportional to engine speed from converter 28 with a reference level on line 34 so that when the engine starts the comparator will provide an inhibiting output to the circuits 20, 24 and the added voltage will rapidly decay as shown at 40 in Fig. 2. Under conditions of malfunction when the fuel pump stops or the engine stalls the circuit 24 is reset by line 38 being de-energized.

Abstract: 912,133. Weighing apparatus. AVERY Ltd., W. & T. May 18, 1960 [May 19, 1959], No. 16855/59. Class 143. An automatic feed weigher feeds a weighing receptacle 7 from a hopper divided into two compartments X, Y from which a bulk and a dribble feed respectively are dispensed, the hopper being filled from one side, opposite the dribble compartment, in such a way that both compartments receive material until the latter is filled and overflows into the main compartment. Feed from the hopper to the receptacle occurs in two stages, the hopper being supplied with material with a gate 8 open at the outlet of the main compartment and the dribble feed inoperative during the first stage and the source of supply stopped, the gate closed and the dribble feed operative during the second stage. As shown, the source of supply is a container 3 situated over a conveyer belt 5 to feed material, at a rate adjustable by gate 4, into the hopper so as to keep compartment Y filled and provide a flow of material through the compartment X to the weighing receptacle. When the weighbeam 15 has tilted sufficiently to operate microswitch 19, this feed is stopped by the simultaneous closure of gate 8 and stoppage of conveyer 5, the material caught by the gate providing a dump feed at the outset of the next weighing cycle. Switch 19 also initiates the dribble feed by starting a vibrator 12 which continues to run until switch 20 is operated, when the vibration is stopped and a dribble catch member 14 is moved to the position shown by a ram 13. Discharge gate 21 then opens to empty the receptacle. The belt 5 may be replaced by a vibrating shoot and the vibrating shoot 11 by a belt.

Abstract: 1,006,763. Magnetic filters. MULLARD Ltd. April 23, 1964, No. 16875/64. Heading B2J. A magnetic filter e.g. for a closed water system in a power station comprises two gratings 22 of ferromagnetic material (one shown, cut away), one extending across the inlet of a non-ferromagnetic housing, and the other across the outlet, each grating having a plurality of parallel slots 24, a plurality of parallel meshes located between the gratings, each mesh consisting of non-ferromagnetic strips 6 extending at right angles to the gratings and supporting ferromagnetic strips 7 extending at right angles to strips 6 (and preferably at right angles to slots 24), and means for applying a magnetic field between the gratings, such as two permanent magnets having the gratings as pole-pieces. One of these magnets may be reversible, to produce zero field between the gratings, so that auxiliary inlet and outlet ducts may be used for automatic backwashing when interruption of a light path through the meshes or pressure drop across the filter indicates clogging. The auxiliary inlet may be dispensed with, pressure downstream of the filter being used to backwash it into an auxiliary outlet. Electromagnets may be used instead of permanent magnets.
