Patent GB-1013042-A (GB)
Title: Shaped articles of poly-ª‡-olefines
Inventor: STIMPSON JAMES WALTER
IPC: C08L23/02
Filed: 1962-05-24
Abstract: Shaped polyolefin articles of improved affinity for dyestuffs may be obtained by adding to a polyolefin, a metal-containing polyurethane, copolyurethane, polyamide or copolyamide in which the metal is of Group II, IIIb or IVa and has a colourless ion, e.g. Zn, Mg, Ca, Al or Ti. The metal may be introduced by reacting a metal salt with the starting materials or the polycondensate. In examples, the additives are derived from (1) Zn acetate, hexamethylene diamine and dimethyl isophthalate; (2) butanediol/hexamethylene diisocyanate and Zn acetate; (3) 11-aminoundecanoic acid and Zn acetate; (4) 11-aminoundecanoic acid, caprolactam and Zn acetate; (5) 11-aminoundecanoic acid and Ca acetate, and (6) 11-aminoundecanoic acid, hexamethylene diammonium adipate and Zn acetate.  The articles may be dyed with disperse, mordant, basic or acid dyes.  Fibres and film are specified as applications.

Patent GB-811924-A (GB)
Title: Labelling apparatus
Inventor: HOWELL RHYS MADDOCK
IPC: B65C3/12
Filed: 1956-06-29
Abstract: 811,924. Labelling machines. DISTILLERS CO. Ltd. June 17, 1957 [June 29, 1956], No. 20142/56. Class 73 [Also in Group XVI] In a machine for affixing labels of preprinted adhesive tape a pair of feed rollers 2 and 3, one of which is driven, are supported so that the nip between them is altered to grip a label when an article 6 to be labelled contacts a labelling roller 5 near to the outlet of the feed rollers; the labelling roller moves the article freely whilst it presses the label on to it. A continuous length of tape from a drum 22, is fed into feed channels 25 and 1 round an intermediate roller 24 which can be pulled laterally out of contact from a continuously driven roller 26 by the action of a spring 27. The channels 25 and 1 have flanged sides which cause the centre of the tape to bow upwards, giving it rigidity. Freely rotating rollers 29 and 3 carried on pivoted arms can move down to co-operate with continuously driven rollers 28 and 2 set in transverse slots across the channels 25 and 1 repectively to nip the tap and feed it forward. The roller 3 is mounted at the opposite end of the pivoted arm 4 to the continuously driven, smooth-surfaced labelling roller 5. The rollers are knurled to assist their feed action. An electrically operated cutting blade 30 is controlled by a switching device 32, as described in Specification 811,923 [Group VIII] to cut the tape into label lengths. The article 6 is fed through a gate 14 (Fig. 3 not shown) down a conveyer ramp 9 which has a cradle 7 with rollers 8 on which the article can rotate freely pivoted at 10 on its lower end. A grid 12 pivoted at 13 beyond the end of the ramp lies partly within the framework of the cradle 7. A cam mechanism and linkage (Fig. 4 not shown) tilts both the cradle 7 and grid 12 in such a way that as an article on the cradle is lifted into contact with the labelling roller, the free end of the grid 12 follows up below it. When the roller 5 has rolled on the label the cradle subsequently falls and the uplifted end of the grid engages the article, picking it from the cradle and permitting it to roll down the grid and off the machine. The movement of the gate 14 is controlled directly by the movement of the cradle 7 so that there is always an additional article waiting on the rear of the cradle to take the place of the one that has just been labelled. The operation of the cradle and the ramp, the cutting and the mechanism and the tape sealing mechanism is effected electrically when the tape touches a switch 32. In the operation of the latter mechanism; through the action of a spring 36 the roller 29 is caused to press the tape on to the periphery of the rotating roller 28. This moves the tape forward along the channel and hence pulls the roller 24 against the action of a spring 27 into contact with roller 26. The roller 24 then becomes the driven component and unwinds the tape from the reel 22.

[Class 38 (iv)] Boosting by dynamo-electric machines; systems depending on two or more sources; ; variable-speed generators, with.-In a system in which constant voltage D.C. load circuits 16, 18 are supplied either from a constant voltage dynamo 1 through a cut-out 23, or from a battery 12 through a booster generator 9 excited by differential windings 10, 11 connected respectively across the battery and load circuit with the current in one winding regulated according to the voltage of the load circuit, an A.C. output circuit 27 of constant voltage is derived from slip-rings 24, provided on the booster motor 7, connected to points equidistant on the motor armature which is connected across the load circuit supply leads. Whilst the battery is charged the carbon pile 14 of a voltage regulator 13, included in the circuit of winding 11, is maintained at maximum resistance value, so that as the battery voltage increases the excitation of coil 10 increases, resulting in increase in charging current. When the load circuit is supplied from the battery, the voltage across winding 10 decreases, and winding 11 under the control of regulator 13 increases the booster voltage in order to maintain the voltage of the D.C. load circuit constant. The booster motor which is started when the cut-out or the load circuit switches 21, 22 are closed, has a resistance 19 included in the armature circuit, which is short-circuited when the voltage across the armature attains a predetermined value. The slip-rings 24 may be connected to the load circuit through a step-up delta/star transformer 25, 26 which may supply discharge lamps. According to the Specification as open to inspection under Sect. 91 the booster motor may be connected across the battery, in which case an additional field winding connected across the booster generator assists the winding 8 whilst the battery is being charged and opposed whilst the battery is being discharged, also the resistance 14 may be short-circuited by a contact when the cut-out 23 closes. This subject-matter does not appear in the Specification as accepted.

A kiln comprises walls defining a ware chamber heated by at least one burner, an air duct in one of the walls, a refractory inspirator in said duct which communicates with the burner and ware chamber, and means for moving air through the duct and inspirator whereby this air is preheated by hot gases withdrawn from the ware chamber and the mixture of preheated air and gases is conducted to the burner. The tunnel kiln shown is suitable for ceramic ware and comprises a firing zone F, heated by oppositely-disposed pairs of burners 2, 4, 5 and 6, and a cooling zone C having side walls formed by thin refractory panels 7, 8 and roof passages 13-16 through which combustion air for the burners is passed for preheating, this air being supplied by a blower 17 through a pipe 18 and admitted to the passages under the control of dampers 13<1>-16<1> operable in pairs 13<1>, 16<1> and 14<1>, 15<1>.

The bush has an annular recess in which is a split spring-ring 44 having a projection or kink which engages with a recess in the plug 30 to locate the closed position of the throttle, and the bush is further provided with gear teeth 43 meshing with a toothed sector 61 secured to a reversing- valve 50. A central passage 58 in the valve is in constant communication with a chamber 25 in the casing 10, and a second chamber 26 communicates with a passage 55, Figs. 2 and 5, in the casing 49 of the valve. In operation rotation of the sleeve 31 in one direction admits fluid through the channel 37 and port 48 to an opening 60 in the side of the valve, whence it proceeds by the passage 58 to the chamber 25 and so by the inlet ports 70 to the cylinders. Exhaust takes place through the cylinder ports 71, chamber 26, passage 55 and a second opening 59 in the valve to a port 56 which is always open to atmosphere. Rotation of the sleeve 31 in the opposite direction causes the inlet and exhaust ports 70, 71 to be reversed, the opening 59 then connecting the ports 48, 55 to admit fluid to the chamber 26 and thence to the cylinder ports 71 while the chamber 25 is connected to atmosphere. The admission of driving fluid through one of the ports 71 during the exhaust stroke of the corresponding piston causes the engine to reverse.
