Title: Can conveying and manipulating
Inventor: SHARPE PETER TALBOT
IPC: B65G47/24
Filed: 1959-05-13
Abstract: 920,763. Conveyers. UNILEVER Ltd. May 2, 1960 [May 13, 1959], No. 16412/59 Class 78(1). In apparatus for upending cans 30 moving in series with their axis disposed in the direction of movement, the cans pass from a shoot 1 between a pair of endless belts 2, 3 and thence to a runway 20 of V-shaped cross-section in the end of which a longitudinally adjustable peg 22 is disposed, the arrangement being such that the peg lies just below the bottoms of the cans on the runway and projects into a position in which it engages and steadies each can as it falls from the end of the runway into upright position on a rotary disc 23. When longer cans 43 are to be upended the runway 20 and peg 22 are disposed at a correspondingly higher elevation, Fig. 4, and a magnet 40 is disposed below the disc 23, which is of stainless steel or other non-magnetic material, to prevent the can falling over on landing. A pair of endless belts may be disposed within the runway 20 to convey the cans along it. The belts 2, 3 are caused to grip the cans by a spring-loaded roller 17 co-operating with a fixed roller below the upper run of belt 3. Guide members 26, 27 guide the cans from the disc 23, a deflector 29 removing any cans still on the disc beyond the discharge point.

Title: Improvements in or relating to the packaging of food
IPC: B65B31/06
Filed: 1952-06-30
Abstract: 700,668. Sealing. DEWEY & ALMY CHEMICAL CO. June 30, 1952 [Nov. 30, 1951], No. 16464/52. Class 146(2) [Also in Group XVII] A machine for packaging food in sealed bags comprises means to evacuate the bags, means to twist the ends of the bags into a hermetically sealed neck and means to apply a sealing clip or band to said neck. A succession of sealing clips 60 threaded on a paper strip 50 is fed from a reel 48 around a wheel 51 , and along a guide 58; the periphery 61 of the wheel 51 cooperating with a groove in the guide 58, Fig. 7, to bend the paper strip 50 longitudinally to allow it to pass out from the row of clips through an elbow 56, the clips being held on the guide 58 by margins 63 thereon and a backing leaf spring 57, Fig. 8. A pawlcarrying arm 69 rocked by a solenoidactuated arm 66 oscillates a pawl 54 to pull the paper strip 50 forward, a second pawl 55 preventing return movement of the strip, and thus cause the end clip 60 on the guide 58 to be pushed into a crimping head 74 positioned adjacent the end of the guide., The crimping, head 74 includes, Fig. 4, pivoted notched crimping jaws 77, 78 urged apart by springs 80 and adapted to co-operate with a punch 83 spring- mounted on a plunger 82 to support the base of the clip 60. The head 74, which is carried by a pivoted arm 75, is rocked from a clip-receiving position to a position in which it surrounds the twisted neck of a bag supported by a table 114. This is effected by a spring 97, Fig. 11, pulling an extension of the arm 75 against a cam 87 on a shaft 91 rotated one revolution through a one-revolution clutch 93. In the bag-engaging position the plunger 82 is moved forward, so that cam faces 79, 81 thereon urge the jaws 77, 78 together, by a pivoted lever 101 rocked, through a lever 98 linked by a spring 99 to the lever 101, by a cam 88 on the shaft 91. A knife 102 carried by an arm 113 pivoted to the head 74 is similarly operated by a cam 89 engaging a lever 111 to slice off the excess bag-neck material. A pivoted block 107, Fig. 15, linked to the arm 75 is adapted to engage a stop 95 of the clutch 93 to stop rotation of the shaft 91 if the arm 75 is unable to reach the bag-engaging position.

A pilesinking devicecomprises a driving tube8 which is subjected to an alternating rotarymotion and carries shrouded elements 10 on the outside face for ratchet engagement with detents on a ring 2 fixed to the top of a penetrating sleeve 1 to drive the latter in one direction only, and blocks 16 on the inside face which engage corresponding recesses in segmentalelements 14 fixed to the outside face of a guide tube 6 for a boring tube 7, to impart the alternating motion of the driving tube 8. to the guide tube 6. The penetrating sleeve 1 has an external helical screw portion 3, a lower cutting portion 5, and internal reinforcing rods 4 which are imbedded within the body of the sleeve 1 and are constrained within the annular space 11 between the guide tube 6 and the inner wall of the sleeve 1. During the boring operation lubricating material, e.g. water, may be introduced into the space 12 between the tubes 6 and 8, the screw portion 3 of the sleeve 1 being provided with apertures 13 for the outlet of the lubricant. When the penetrating means has attained the desired level, the central bore is deepened and filled with concrete B, reinforcements 17, provided with rods 18, being let down through the tube 6, which is then removed, so that the reinforcements 4, and 18 interlace. The concreting of the pile is then carried out, the sleeve 1 serving as a base for the pile. Specification 739,471 is referred to.

Title: Cleaning and polishing cloth
IPC: A47L13/17
Filed: 1971-05-24
Abstract: 1348526 Cleaning and polishing cloths P F FEIG 24 May 1971 [18 July 1970] 16585/71 Heading A4F [Also in Division C4] A cleaning and polishing cloth comprises a carrier material and particles of a porous oxide gel bound to the carrier material by a polymeric binding agent, which anchors the particles but does not penetrate them, the particles projecting from the binding agent. Preferably the particles are of synthetic silica or alumina gel and the preferred particle size is 1À5Á to 60Á. The carrier may be a non-woven fabric of viscose, rayon, cotton or rayon-cotton mixtures. Binding agents mentioned are polyacrylates, polymethacrylates, polyvinyl chloride, polyvinylidene chloride and polyvinyl acetate. Penetration by the binder into the particles is prevented by selection of the polymer or by pre-treating the particles with dilute aqueous ammonia. The particles are applied to the carrier as a slurry in the binder dispersion, the ratio of particles to binder being high enough to ensure that they project from the binding agent in the finished product.

Abstract: 344,903. Anti-aircraft gunnery. JACKSON, L, MELLERSH-, 28, Southampton Buildings, London.-(Aktiebolaget Bofors ; Bofors, Sweden.) April 30, 1930, No. 16693/29. [Classes 92 (i) and 92 (ii).] Sights and methods of sighting; mountings.- Consists in means for controlling the elevating and training of anti-aircraft guns to suit a method of aiming according to which, during the flight of the first projectile, a succession of projectiles is fired at progressively diminishing angles of elevation, the gun being directed for each succeeding shot to the point reached by the preceding projectile. The effect obtained, according to a theory developed in the Specification, is that, when the time of flight of the first projectile has expired, the projectiles are distributed in a straight line colinear with the axis of the gun barrel. The principle is also applicable to controlling the angle of training to correct for lateral deflection due to drift. In the apparatus shown in Fig. 3, the elevating-gear C is operated through a differential gear D by a hand-gear F<1> and by a variable-speed friction gear L, M, driven from an electric motor E<1>. The training-gear G is similarly driven by a hand-gear J<1> and by a frictiongear L<1>, N, also connected with the motor E<1>. The speeds of elevating and training conveyed by the motor E<1> are controlled by adjusting the friction gears through the medium of graduated slides R, T respectively.

Title: Drying oils from steam-cracked petroleum fractions
IPC: C08F240/00
Filed: 1955-06-14
Abstract: A synthetic drying oil is prepared by polymerizing, using 1.2 to 8 parts of an alkali metal catalyst per 100 of monomers, a C4 cut obtained by steam cracking a petroleum fraction either alone or mixed with a minor amount of styrene.  It is preferred that an acyclic ether or a cyclic ether having oxygen atoms separated by at least two carbon atoms is used as a codiluent and that the temperature of polymerization is from 50-100 DEG  C.  An approximate composition of the C4 cut shows that butenes butadiene-1.3, and butanes predominate. Up to 50 per cent, based on the catalyst, of an alcohol, e.g. isopropanol, isobutanol, isopentanol, sec.-butanol and t-butanol may be present.  Specified ethers are diethyl ether, methylal, ethylol methyl acetal, t-butyl methyl ether, diethyl acetal, vinyl isobutyl ether, dihydropyrane, dioxane, dioxolane, paraldehyde and glycol ethylidene diacetal.  The process may be batch or continuous and the catalyst destroyed by excess of an anhydrous C1-C5 fatty acid, e.g. acetic and pentanoic acids.
