Title: Improvements in or relating to lawn mowers
Inventor: CONSTABLE FREDERICK JOHN
IPC: A01D34/00
Filed: 1969-08-19
Abstract: 1,253,403. Lawnmowers. MANNA ENG. PRODUCTS Ltd. 3 Nov., 1970 [19 Aug., 1969], No. 41234/69. Heading A1F. [Also in Division A4] A lawn-mower is provided with a rotatable brush device in place of the front roller. The brush device 1 comprises four bristle-carrying members 2 each carrying a plurality of bristles 3 on a rigid strip (13), the bristles preferably made from plastics. Each bristle carrying member 2 is carried in a substantially U-shaped channel 6 fixed relative to the other channels and to metal end plates 8. The bristle-carrying members 2 are connected to the U-shaped channels 6 by nuts and bolts 10 so that the bristles 3 project outwardly beyond the circumference 11 of the side wheels 4. As the lawnmower is pushed along (Fig. 2) the bristles become distorted as at 19, and because of their resilience flick into their normal position at 20, simultaneously lifting the grass into the path of the cutters. The tufts of bristles are held on the strips (13) by staples. In a modified form of the brush device 1 (Figs. 4 and 5) the channels 6 are angularly displaced relative to one another about the rotational axis, and the bristles 3 are clamped between two C-shaped strips 30, 31 and angled such that the bristles on one side overlap the gap 34 between bristles on the other. The strips 30, 31 are held together by overlapping tabs 32 on strip 31. In further embodiments, the bristles need not extend further than the circumference of the wheels, and parts may be made of steel or plastics.

A vehicle recovery crane 10, Fig. 1, mounted on a tractor vehicle 11 comprises a frame assembly formed by a longitudinal beam 12 at one end of which is secured a cross-beam 13, Fig. 2, an A-frame 14 extending upwardly from the beam 13 and a tie member 15 extending between the top of the A-frame and the other end of the beam 12, a coupling member 26 which is mounted on the beam 12 and is engaged with the vehicle 11, the member 26 being adjustable longitudinally of the beam 12, swivelling side plates 33, Fig. 5, mounted on the ends of the beam 13 which grip the vehicle 11 and are adjustable longitudinally of the beam 13, and means for connecting to the crane a vehicle to be recovered. The members 12 ... 15 of the frame assembly are of rectangular hollow section tube and can be dismantled for transport purposes. The coupling member 26 is a king pin and is engaged with a fifth wheel coupling (not shown) on the vehicle 11; it is secured to a channel member 19 slidably engaging the beam 12 and locked by a pin (23), Fig. 3 (not shown), passing through aligned holes in the member 19 and the beam 12, a series of such holes being provided for adjustment of the member 19. Each swivelling plate 33 is carried by a foot 28 slidably mounted on a guide 29 on the beam 13 and secured in adjusted position by a pin 30 engaged in aligned holes in the foot 28 and the guide 29. The frame assembly is also secured to the vehicle 11 by a chain 34. A winch 35 which may be a self sustaining gear winch is secured between the limbs of the A-frame 14 and has a cable 36 extending therefrom to two 3-sheave blocks 37, Fig. 6. An A-shaped drawbar 38 is pivoted at 39 to the beam 13 and has connected to it in a swivelling manner a chain spreader 40, the connection being by a tube 41 capable of limited lateral articulation and outward extension. In operation as the vehicle to be recovered is lifted and drawn towards the crane the tube 41 is automatically retracted into the drawbar where it is locked in adjusted position by a pin 42. In order to relieve the cable 36 of load during towing a chain 43 is attached between the chain spreader 40 and a hook 44 on the A-frame 14. The chain spreader 40 is formed with slots (not shown) for securing chains 45 attached to the towed vehicle. Securing brackets 46 are provided on the A- frame 14.

Abstract: 1,041,049. Sheet delivering apparatus. VSESOJUZNY NAUCHNO-ISSLEDORATEL'SKY INSTITUTE GOZNAKA. Feb. 3, 1964 [Nov. 2, 1962], No. 41617/62. Heading B6H. [Also in Division G4] A pile of sheets is counted by a rotating disc 1 which engages between adjacent sheets and climbs the pile by sucking each sheet downwards to pass through a slot 4 in the disc. In its passage through the slot the sheet cuts off the pneumatic suction to operate a pneumatic-electric transducer 16 so as to operate a counter 161. At a predetermined count a solenoid 18 causes a device 21, shown in more detail in Fig. 4 to insert a strip cut from a reel 63 of paper. This is effected by the solenoid 18 connecting duct 14 to atmosphere instead of the vacuum pump 20, whereby bellows 64 drives quadrant 51 and gear 53. The disc 1 is carried by a parallelogram linkage, Fig. 2, so that it can climb up the pile for a limited distance until motor 3 is deenergized. A further motor then drives supporting arm 29 upwards through a screw 45 and the motor 3 restarts to continue the operation. Reference has been directed by the Comptroller to Specification 937,463.

Abstract: 1449662 Rolling tubes VALLOUREC USINESA TUBES DE LORRAINE-ESCAUT ET VALLOUREC REUNIES 7 Sept 1973 [8 Sept 1972] 42092/73. Heading B3M A seamless metal tube is produced by piercing a solid bar with a mandrel to provide a tube blank surrounding the mandrel, and then rolling the blank, together with the mandrel, in a continuous rolling mill. The speed of the mandrel in the rolling mill is controlled, the mandrel is removed from the blank, it is then cooled and lubricated, and returned to the beginning of the installation for piercing another bar. The mandrel is supplied with a piercing head which can optionally be removed before the continuous rolling mill. Solid bars c are initially heated in a rotary hearth furnace 1 and are pierced in a stand 4 comprising skewed rolls while supported on a mandrel M. The resulting hollow blanks while still supported on the mandrels, are rolled in a continuous mill 12 having, successive stands arranged at 90 degrees to each other. The trailing ends of the mandrels are supported at 13 during rolling so that their speed can be controlled and they can be released after rolling. The mandrels are removed from the tubes E after rolling, and the tubes are cut by saws 18 and delivered to a furnace 19, whereas the mandrels are cooled at 17, lubricated at 21, and re-used in the piercing stand 4.

Title: A new cyanogen chloride polymer and a process for the production thereof
IPC: C01C3/00
Filed: 1960-12-08
Abstract: The invention comprises tetrameric cyanogen chloride of formula (ClCN)4.  It is prepared by reacting chlorine with hydrocyanic acid in a closed vessel in tetrachloroethane as reaction solvent, separating the crystallized cyanuric chloride and distilling the liquid under sub-atmospheric pressure to eliminate tetrachloroethane and dissolved cyanuric chloride to yield the tetramer.  In a modification the reaction mixture may be degasified to remove hydrogen chloride, divided into two portions, chlorine is dissolved in one portion and hydrocyanic acid in the other and there are then further reacted, crystallized cyanuric chloride being separated after each third degasification stage. Specification 974,229 is referred to.

[Also in Division F2] A high speed e.g. false-twisting, textile spindle is frictionally driven into rotation by engagement with a belt and is mounted in upper and lower bearings. As shown, each bearing comprises a housing 18 securing a mount 24 of porous metallic material e.g. sintered bronze, and having a bore 40 with a flare at 42 to accommodate a spindle portion 54 and its tapered shoulder 56. The mount is supplied with lubricant from an oil-absorbent felt 66. Radial slots 44 in the side of the mount remote from the belt each slidably house a bearing segment 48 of wear-resistant material e.g. metal, carbon, natural or synthetic sapphire, with a planar surface 50 which bears tangentially against the spindle surface and a convex surface 58 which bears against a load distributing plate 46 inwardly constrained by an O-ring 60 of rubber or like resilient or expansible material. Axial thrust in either direction is transmitted from faces, as at 52, through washer 34 and dished retainining ring 32 to the housing. The outer face of the segment may be flat and bear rockably on the O-ring, Fig. 7 (not shown) or it may bear against a pad of rubber &c. which rests against the bottom wall of each slot 44 and replaces the O-ring, Fig. 6 (not shown). In another embodiment, Fig. 3 (not shown) a single bearing segment housed in one slot in mount 24 provides two faces tangential to the spindle portion 54.
