[Classes 100 (i) and 100 (ii).] Cylinder machines; sheet carriers, guides, and registering devices.-Sheets are fed to the impression cylinder 21 of a cylinder machine, of the kind in which the bed and cylinder carriage 11 are reciprocated in opposite directions, by means of reciprocating suction nozzles 3<1> which are carried by a tube 3 which is reciprocated upon longitudinal guides 7 secured to the machine frame 6. The tube 3 is arranged under the feed table which is formed of a material 4 in which frictional electricity is not set up, e.g. of aluminium, and the nozzles extend into slots 41 in the table 4 but do not extend above the upper surface thereof. The sheets are fed from a pile 1 by means of a suction tube 2, and when the front edge of the sheet is taken by the nozzles 3<1>, the tube 3 is reciprocated by means of a spiral cam 12 on the shaft of the impression cylinder and a lever 9 which is connected by a rod 8 to the tube 3 and gives it a movement additional to that of the cylinder carriage 11. The edges of the sheet are prevented from rising by means of adjustable rakes 13. The sheets are fed against front stops 5 and the suction in the suckers 31 is broken and the sheets are then acted on by suction in apertures 14 on the plate 4. The stops 5 are then moved to engage the front edge of the sheet and push it rearwardly so as to eliminate inaccuracies in the forward feed. The sheet is registered laterally by a reciprocating pusher 15. A hand-operated valve 25, Fig. 2, is used to cut off the suction when hand-feeding is required.

Abstract: 370,587. Automatically c h a n gin g bobbins in multicolour loom shuttles. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Crompton & Knowles Loom Works ; Worcester, Massachusetts, U.S.A.) Feb. 28, 1931, No. 6361. [Class 142 (iii).] A bobbin released from one of the compartments of the magazine by the rocking of the cradle 12 thereof moves along supports 24, 25 to a position beneath the transferrer arm 44 which extends through a slot 31 on a plate 30 formed with a bridge part, so as to guide the bobbin butts continuously during its passage to transfer position. The transferrer arm comprises two parts 41, 45 connected by a bolt 51 and furnished with separate hubs 42, 46 mounted on a stud 43 held by a fixed hub 47 on the plate 30. Spaced lugs 52 on the hub 46 support a pin 53 carrying a latch holder 54 adjusted by a screw 58 and held in position by a transverse bolt 59. When a bobbin is in transfer position, a rod 70 is raised to elevate the latch 55 into the path of a lay bunter 57, whereby, if the shuttle is properly positioned, the transferrer is rocked about the stud 43 and its heel 44 pushes a full bobbin into the shuttle. A spring 62 connecting a finger 61 on the hub 46 and a finger 60 on the holder quickly lowers the holder, assisting the usual action of gravity to lower the latch out of the path of the lay bunter 57 and thus prevent transfer when the rod 70 is lowered by the usual shuttle feeler in case the shuttle is improperly positioned. The rocking of the cradles 12 is controlled by slides 11 having projections 13, 14 operated by fingers 15 on a colour slide 16, which is moved longitudinally by a spring 18 and a cord 17 connected to the box motion &c., and is rocked by means referred to.
Patent GB-743260-A (GB)
Title: Improvements in or relating to methods of producing resinous condensation products
IPC: C08G63/48
Filed: 1952-03-12
Abstract: Infusible resinous masses are produced by reacting a di- or tri-glyceride of a fatty acid having conjugated unsaturation with a compound containing at least two dienophilic groups in the molecule, the number of diene or dienophilic groups exceeding by not more than 50 per cent those of the other kind, and hardening the solvent-free liquid by heating.  Suitable glycerides are those of eloeostearic acid, e.g. tung oil or those of licanic acid, e.g. oiticica oil. Substances with two dienophilic groups are quinone, chelidonic acid, 1,5-dihydroxy-1,5-dicarbethoxy - 3 - keto - pentadiene - 1,4 (the enolic form of acetone dioxalic ethyl ester), dibenzalacetone, the condensation product of two mols. of furfural with one mol. of cyclohexanone in which the furfural residues are attached by double bonds to the 2 and 6 carbon atoms of the cyclohexanone, and polyesters from a ,b -unsaturated dicarboxylic acids such as maleic, fumaric or citraconic acid and a polyalcohol such as glycol, glycerol, butane-diol pentaerythritol or castor oil.  The polyester may be modified with a fatty acid such as stearic or with a monohydric alcohol preferably containing at least 4 carbon atoms to improve its solubility in tung or oiticica oil.  The products are liquids, hardening with heat without production of gas or volatile products.  They are suitable for impregnating the windings of electric motors or transformers.  Active diluents containing a diene or dienophilic group may be added to the reaction mixture. Examples are ethyl esters of maleic, fumaric or citraconic acid which have one dienophilic group, and a -phellandrene or cyclopentadiene which have a diene group.  Styrene may also be used as a diluent since it can react with a dienophilic group. The amount of styrene may be greater than that which will combine with excess dienophilic group.  If it is a much greater a polymerization catalyst may be needed for hardening. A substance such as hydroquinone will inhibit polymerization of tung or oiticica oil without greatly affecting the polymerization of the styrene.  In the examples I quinone is dissolved in tung oil at 100 DEG  C. to give a heat-hardenable solution.  II acetone dioxalic diethyl ester or the cinnamic ester of pentaerythritol is dissolved in tung oil III.  A polyester from triethylene glycol and maleic acid anhydride is dissolved in tung oil.  IV Polyesters from glycol, meleic acid anhydride and castor oil were dissolved in tung oil or oiticica oil.  V. A Polyester from butane diol and maleic acid anhydride was dissolved in tung oil.  VI.  A polyester (acid value 32) was prepared from butanediol 2, 3; glycerine, maleic acid anhydride and stearic acid.  Dissolved in tung or oiticica oil it yields a heat-hardenable solution.  Mixed with tung or oiticica oil, styrene and hydroquinone it yields an impregnating varnish for wire windings.  VII.  The polyester of example VI was mixed with tung oil and a -phellandrene. Specification 588,392 is referred to.

Filed: 1976-02-19
Abstract: 1477128 Apparatus for cleaning submerged surfaces F L O J CHAUVIER 19 Feb 1976 [25 Feb 1975 24 March 1975] 06551/76 Heading A4F [Also in Division F2] Apparatus 10 for automatically cleaning a surface submerged in a liquid e.g. the floor and walls of a swimming pool, comprises a cleaning head 12  having a peripheral region 20.1 releasably engageable with the surface to be cleaned; two passages 14.1, 14.2 in suction communication with the head via openings 28, and a flap valve 16 arranged to automatically divert liquid flow from the head first to one passage and then to the other in an alternating and repetitive manner. The cleaning head may comprise a member 22 provided with a flow directing opening 31, and may have a sealing flange 34 of flexible material rotatably mounted on base member 20. The latter may be provided with relief openings 36. The passages may be defined by pipes 40, which the end remote from the head may be secured to a junction member 42 having a swivel coupling 48 for connection to a hose. A buoyancy member 52 may be secured to the upper pipe, and ballast in the form of a lead ball 54 movable in the arms of a V-shaped housing 56 may also be provided. To operate the apparatus, suction pressure is applied so that water is sucked through mouth 24 and relief openings 36 into for instance, passage 14.2 via chambers 31 and 26. The flow of water past valve 16 causes it to be displaced away from the valve seat 30 for passage 14.1 to the valve seat for passage 14.2 permitting water to flow into passage 14.1. The consequence of this action is that the apparatus is displaced slightly in the direction of arrow 50. The valve is then diverted back to the valve seat for passage 14.1 by the flow of water, and the process is repeated. In this way, the apparatus migrates across the floor of the pool. In a modification, Figs. 4, 5, (not shown) the passages are defined by a partition in a pipe and are arranged side-by-side, and the valve pivots about an axis that is at an acute angle to the plane in which the peripheral region lies. The apparatus in this case tends to move in a zig-zag manner. The flange 34 in this case may be attached to the head by studs and its undersurface may have pieces of sandpaper adhered to it.
