Title: Improvements in or relating to the treatment of chlorine-containing rubber derivatives
IPC: C08C19/14
Filed: 1945-05-23
Abstract: Chlorinated rubber, hydrochlorinated rubber or chlorinated hydrochlorinated rubber is improved, particularly as regards clarity, light transmission, viscosity and odour by a process which comprises injecting chlorine into an aquerous suspension of the chlorine containing rubber material at a temperature above 20 DEG C.  The optimum temperature is 70-95 DEG C. through temperatures above 100 DEG C. may be used in a pressure vessel.  The chlorine containing derivative of rubber is preferably treated in the form of granules obtained by forming the derivative in solution and then injecting the solution into hot water causing the solvent to flash off, pulverised material or thin sheets may also be so treated.  During treatment the temperature may be raised and lowered one or more times in order to free impurities and entrapped gases.  Examples are given to illustrate the improvement when chlorinated rubber is treated in contact with water at 70-100 DEG C. and also in contact with steam. In a further example chlorinated rubber solution produced by the action of chlorine on rubber dissolved in carbon tetrochloride is blown to remove excess chlorine and then injected into hot water treated with chlorine and water in two successive steps and then dried.  In a modification of this example the chlorine saturated solution of rubber hydrochloride is injected directly into hot water containing free chlorine.

Title: Improved means for controlling the operations of testing machines worked by rotary variable capacity pumps
IPC: G01N3/10
Filed: 1919-05-22
Abstract: 149,787. Meacock, T., and Variable Pumps & Motors, Ltd. May 22, 1919. Governing and regulating pumps.-In a hydraulic testing machine controlled by a rotary driven variable capacity pump, means are provided for regulating the delivery of pressure fluid whereby any movement of the control means of the pump due to a rise in pressure in the hydraulic cylinder increases the stroke of the pump pistons to such an extent as to compensate for leakage in the pump. This is accomplished by imposing a particular law or formula connecting the pressure in the hydraulic cylinder with the movement of the rotary-pump control ring. As shown in Figs. 3 and 4, a gear-wheel 1 is mounted on the screwed spindle 2 of the control ring which varies the stroke of the pump pistons; the wheel 1 engages the teeth 4 of a rack 5 which is provided with another row of teeth 8 at right-angles to teeth 4 engaging a gear-wheel or quadrant 6 mounted on a spindle 9, to which is secured a pendulum 7 having an adjustable weight 20. Attached to one end of the rack 5 is a plunger 14, Fig. 5, adapted to slide to and fro in a cylinder 13 connected by a pipe 16 with the pressure end of the test cylinder. In making a test, the pendulum is set to a position at which the pump delivers the quantity required for the test when there is no pressure in the stress cylinder, due to the travelling weight of the testing machine steelyard. As the weight moves, it sets up a pressure in the stress cylinder which is transmitted to the plunger 14 and forces the plunger outwards, thus moving the rack 5 and thereby the control ring of the pump to an appropriate extent to compensate for leakage and maintain the delivery. The normal position of the pendulum is determined by means of a quadrant 25 and adjustable collar 26 on which is mounted a buffer spring 29. Modifications are described, in which the rack is made hollow and the pendulum is replaced by a spiral spring surrounding a rod passing through the hollow centre of the rack, or the rack is attached to a cord passing over a pulley and a series of weights is raised consecutively, or bevel gear is employed in lieu of the spur gearing and the spring is arranged on an arm extending from a shaft of one of the bevel gears, or the control ring of the pump is operated bv an eccentric instead of by means of a screwed shaft.

Title: Improvements in radiant superheaters
IPC: F22G1/16
Filed: 1957-04-23
Abstract: 805,528. Steam superheaters. COMBUSTION ENGINEERING Inc. April 23, 1957 [April 23, 1956], No. 12915/57. Class 123(3) An independently-fired superheater comprises a vertical furnace F lined with radiantly-heated superheater tubes 14, 18 and fired by corner-mounted, tangential firing burners 28, the furnace gases flowing through a lateral outlet D into a downpass E lined with superheater tubes and in which are located convection superheaters 24, 25. To prevent overheating of the tubes immediately above the burner zone and to give a more even heat distribution through the unit, flue gas is withdrawn from the bottom of the downpass by a fan 34 which supplies it through a duct 33 into a duct 36 which surrounds the furnace F above the burner zone. The superheater tubes 14, 18 form the inner boundary of the duct and in this peripheral region are slightly offset, are of oval section or are swaged to a smaller diameter to provide outlet ports for the gas through which it flows at low velocity into the furnace. The rotating gas mass rising through the furnace pushes the recirculated gas against the tube-lined furnace walls whereon it forms a moving blanket, indicated at 40, screening the tubes from excessive radiation.

Title: Improvements in separable bond assembly and method of producing the same
IPC: C09J7/21
Filed: 1962-04-09
Abstract: 967,835. Coated sheet material. PEELBOND PRODUCTS Inc. April 9, 1962 [April 12, 1961], No. 13572/62. Heading B2E. A separate bond assembly comprises a layer of waterproof hydrophobic material having dispersed therein a substantially non- volatile hydrophilic water-penetrant agent and an aqueous adhesive disposed on and penetrating a surface of the layer for only or part of the depth of the layer. The water-penetrant agent may be an emulsifier, a wetting agent, or a mixture thereof. The hydrophobic assembly may include a layer of a substantially waterinsoluble synthetic organic resin which may be a thermoplastic resin. The assembly may comprise a strippable laminate having a web 10, the first layer 11 of the water-insoluble synthetic organic resin being affixed to a surface of the web and the second layer 12 consisting of the aqueous adhesive disposed along and penetrating the face of the layer remote from the web. The web may be fibrous or non- fibrous, e.g. paper, Kraft, tissue, printing or wall paper, wall covering, paper or fibre board ; the first layer may be a fused synthetic material superimposed upon a surface of the web, the fibres of the web being imbedded in the first layer. The assembly may be characterized by the strippable laminate including a base surface 13, the face of the second layer remote from the first layer adhering to the base surface. The adhesive bond between the first and second layers is less than the cohesive strength at the first and second layers respectively and less than the bonds between the first layer and the web, and between the second layer and the base surface. The adhesive may be a water-based, water-sensitive or water-activated adhesive. The assembly may be produced by applying to a face of a web a coating of aqueous emulsion of a synthetic organic resin, e.g. a thermoplastic resin, the emulsion carrying a non-volatile water-penetrant agent, evaporating the water from the emulsion, e.g. by heating, to coagulate the resin to form a layer bonded to the web and applying to the surface of the layer opposite the web a layer of an aqueous adhesive, so that said adhesive penetrates the layer for only a part of the depth thereof. The adhesive may be dried, the surface of the adhesive remote from the layer rewetted, and the rewetted surface applied to the surface of a substrate. Examples of suitable adhesives, water-penetrants, and hydrophobic materials, are given.

Title: Improvements in or relating to Grabs.
Inventor: PALIN JOSEPH
IPC: B66C3/18
Filed: 1917-09-25
Abstract: 121,756. Palin, J. Sept. 25, 1917. Grab-buckets. -- Relates to grab-buckets having electricallyoperated scoops and to the controller for opening and closing the scoops. The grab casing a., Fig. 1, carries pivots c on which the scoops b are mounted the inner ends of the scoops carrying arms d connected by a horizontal shaft e. Chains &c. k are secured at one end m to the casing and, after passing downwards and under the shaft, return upwards and are secured to a winding-shaft ! i connected by worm gearing to a driving-shaft f at right-angles to the winding-shaft carrying one or a pair of electric motors g, h. Rotation of the motors to unwind the chain allows the scoopoperating shaft to fall and the scoops to open. The electric motor control system is shown diagrammatically in Fig. 4, the armature windings g<1>, h<1> and the field windings g<2>, h<2> being connected in series and the rnains r, s connected to the fixed supply contacts 2, 12 of a set of fixed contacts 1, 14 on the controller, the drum of which carries a set of contacts 1<a>, 13a for forward running and another set 2<b>, 14<b> for reversed running. When the controller drum is in the neutral position A, its contacts are inoperative. When it is rotated into position B, a circuit is made through contacts 2, 2a, 1<a>, 1, lead 1<c>, winding u of a retaining auto-switch, lead 13<c>, and contacts 13, 13<a>, 12a, 12, which closes the movable contact u<1> of the switch. This completes the circuit of the armature and field windings through the retaining resistance 18 and variable resistance 19. The resistances, however, are such that the motors remain stationary until the drum is moved to the position C, when the contact 3<a> engages the contact 3 and closes the circuit of the winding v of a main auto-switch, so that its movable contact v<1> closes and short circuits the retaining resistance 18. The motors now slowly rotated forwards to close the scoops and further rotation of the drum brings the contacts 5a, 6<a> 7<a> into action and successively cuts out the sections of the variable resistance 19, so that the motors speed up to the maximum. Should the scoops be fully closed and the controller drum not be put in the inoperative position, the excessive current actuates a stop magnet x, in the motor circuit, to open a stop switch w and thus open the circuit of the winding v of the main auto-switch which thus opens and so stops the motor, the retaining resistance being at the same time put into the motor circuit. By turning the drum backwards to the position G the circuit of a resetting magnet y is closed, thus reclosing the stop switch wand the main autoswitch v. The motor circuit also is closed for reverse running. A second stop magnet 16, switch 15, and resetting magnet 17 are provided to stop the motors if the current becomes excessive.
