Title: Improvements in or relating to flax harvesting machines
IPC: A01D45/06
Filed: 1925-04-24
Abstract: 234,464. Vershaeyen, A. May 26, 1924, [Convention date]. Flax-pulling machines; harvesting-machines.- The flax or other crop is directed by dividers 20 and a guide 21, 22 between pairs of endless belts 13, 18, the belt 13 being driven by a vertical roller 10 and passing over an idle roller 14 and the belt 18 passing over idle rollers 16, 17, 19. Shields 23 guide the upper part of the plants or the belts may be made as wide as the height of the plants. The rollers are driven by gearing from one of the main wheels of the machine. The plants are delivered to a binder or deposited on the ground. The Specification as open to inspection under Sect. 91 (3) (a.) states also that the belt 18 may be positively driven and that the machine may be used for pulling out plante other than flax plants.

Title: Improvements in or relating to hedge cutters
IPC: A01G3/04
Filed: 1953-04-18
Abstract: 760,110. Hedge-cutters. FULLER, A. July 16, 1954 [April 18, 1953 ; Dec. 3, 1953], Nos. 10669/53 and 33696/53. Class 6(2). A hedge-cutter has a power-driven reciprocating mower-bar 16 carried at one end of a beam 17 which is pivotally mounted for rotation about a longitudinal axis upon a part carried by a pair of arms 4 pivoted on a tractor chassis 1 and raised and lowered by rams 5. In Figure 1 the beam 17 is pivoted on an axle 10 projecting from a beam 7 pivoted to the two arms 4 about a transverse axis and adjustable thereabout by a turnbuckle. The cutter 16 is driven by a motor 18 at one end of the beam 17, the arrangement being substantially balanced about the axle 10 so that the beam may be swung by a handle 38, into an inclined position. The fixed cutter is carried by an arm 27 rotatable about the axis of the driving pulley 21 and may be secured in any position relative to another arm 34 by a bolt 33. The arm 34 with a parallel arm 36 and a link 35 forms a parallel-motion linkwork causing the cutter 16 always to remain parallel to itself on moving the beam 17. The cutter can be swung back over the beam and the latter raised to the dotted position for transport. In Figure 5, the beam 64 is carried by a pivot 63 carried by brackets hanging from a beam 40 pivoted to the arms 4, the beam having an integral bracket 42a which receives the end of a rod 45 slidably and yieldingly passed through an aperture in a cross-bar 52. The bar 52 is pivoted between arms 53 which, together with the arms 4, bracket 42 and rod 45, forms a parallel linkwork. The springs 50, 51 permit the beam 40 and cutter bar to swing back slightly on meeting obstructions. The brackets 56, 61 embrace the beam 40 and carry a roller 62 enabling the beam 64 and cutter to be adjusted transversely by releasing locking-bolts 58. For transport the beam 64 may be removed from the pivot 63 and a tube 72 on the beam engaged with the pivot so that the beam and cutters extend longitudinally.

Abstract: Linear copolymers of one or more monoalkenylcyclobutenes with ethylene and one or more aliphatic alpha-olefins of the general formula R-CH = CH2, wherein R is a C1 to C6 alkyl group are made by copolymerizing in the liquid phase in the presence of a halogen containing catalyst obtained from a vanadium compound and an organometallic compound of aluminium or beryllium in which at least one of the compounds contains a halogen atom. The catalyst may be prepared, and the copolymerization carried out at 0 DEG  to - 80 DEG C.  The copolymerization may be effected continuously or batchwise, in bulk, or in the presence of an inert solvent.  The aluminium compound may be complexed with a weak Lewis base such as an ether, thioether, tertiary amine, or trisubstituted phosphine.  The cyclobutenes may be 3-methyl-4 - (4 - pentenyl) - cyclobutene, 3 - (1 - methylallyl) cyclobutene, or 3-(5-hexenyl)-cyclobutene. The alpha-olefins may be propylene or butene-1.  The copolymers may be vulcanized, or extended with paraffinic, naphthenic, or aromatic oils.

Title: A machine for filling containers such as cans, jars or the like
IPC: B65B3/32
Filed: 1947-04-24
Abstract: 634,214. Bottling. MARCHADOUR, H. April 24, 1947, No. 11050. Convention date, March 26, 1943. [Class 125(ii)] [Also in Groups II and XXVIII] A machine for filling cans, jars and like containers with measured quantities of material, particularly solids in liquids such as fruits in syrup, comprises: -measuring distributors 8 acting by induction and ex- _pulsion disposed around, and rotating with, a rotary reservoir 6; means for putting each distributor during each revolution of the reservoir into alternate communication with a corresponding lateral opening 10 in the lower part of the reservoirs and with an outlet opening 132 to the corresponding container r which moves at the same angular speed as the reservoir; and a vertical conveyer screw 23 rotating in the reservoir in the opposite direction thereto so as to convey solids from the surface of the liquid to the neighbourhood of the openings 10. As shown, distributors 8 constitute pumps the pistons 9 of which we reciprocated by means of a fixed guideway 20 of adjustable inclination. During the induction stroke, each pump cylinder communicates with reservoir 6 via an opening 12 and a corresponding opening 12<SP>1</SP> in a rotary cock 11. As piston 9 approaches top dead centre, the container r acts on a rocker 17 to cause a finger 15 to project into the path of the cock control lever 14; the cock is thereby rotated to close opening 12<SP>1</SP> and to allow the contents of the cylinder to be discharged, during descent of the piston, into container r via openings 13<SP>1</SP>, 13<SP>2</SP>. When piston 9 reaches bottom dead centre, a fixed finger (not shown) turns lever 14 back to restore cock 11 to its initial position. Screw 23 is offset from the reservoir axis towards the point at which the pump induction stroke ceases, the screw threads having a downwardly-turned rim for retaining the solids conveyed thereby.
