Patent GB-824433-A (GB)
Title: Continuous production surfacing of thermoplastic sheet and film
IPC: B29C43/22
Filed: 1957-06-17
Abstract: <PICT:0824433/IV (a)/1> A continuous web of organic thermoplastic material is produced by forming a web of film or sheet from a mass of the material by means of a calender of heated rolls, of which the last is a heated rotating hard, rigid back-up roll, heating the web to a desired working temperature on the heated rotating back-up roll by causing the web to pass over and in contact with a substantial portion of the peripheral surface of the roll, passing the resulting heated web through a nip formed between the back-up roll and a hard, rigid counter-rotating surfacing roll maintained at a lower temperature than the back-up roll and having a peripheral surface for applying a desired finish to the web, subjecting the web in the nip to a pressure sufficient to obtain complete mating of the web to the peripheral surface of the back-up roll, continuously adjusting the distance between the rolls to provide the needed clearance for the web to pass through the nip under such pressure but without forming a bank of the material therein, the speed of the surfacing roll being so regulated as to cause the web to leave the back-up roll after passing through the nip and follow the surfacing roll in contact with a substantial portion of its peripheral surface, and stripping the web from the surfacing roll after it has been cooled on the surfacing roll to a temperature at which it is form-stable.  As shown, a mass of thermoplastic organic material 10 is introduced into a calender comprising hard, rigid heated rolls 12, 14, 16 and 18 which are rotatable on fixed parallel axes, adjacent rolls being oppositely rotatable.  Roll 18 is a back-up roll.  The material is formed into a web 10a which passes through the nip between roll 18 and a hard, rigid surfacing roll 20 having a desired peripheral finish.  The roll 20 is rotatable oppositely to roll 18 about an axis which is laterally displaceable with respect to the axis of roll 18, and is urged towards roll 18 by a yieldable pressure loading system.  This may comprise a fluid-pressure cylinder 22 having a plunger 23 acting on the shaft 24 of the roll 20.  The roll 20 is maintained at a lower temperature than the roll 18 and is preferably driven at the same or a slightly faster peripheral speed than the roll 18.  The web 10a is made to follow the surfacing roll 20 after its passage through the nip between rolls 18 and 20 and thereafter passes over stripping roll 25, which is preferably driven at a peripheral speed about 3% above that of roll 20.  The web then passes over idler rolls 26 and cooling rolls 27 to a wind-up roll 28.

Title: A process for producing chemically pure, toxic free narcotising ether
IPC: C07C41/44
Filed: 1923-07-24
Abstract: Pure ether is prepared by dissolving benzidine or a homologue or substitution product thereof in crude anhydrous ether at ordinary or increased pressure, allowing the ether salts of crystallization to form and regenerating the ether by heat from the separated crystals. Thus, finely-powdered benzidine is dissolved, preferably under pressure, in boiling crude ether which has been rendered anhydrous by treatment with quicklime, or sodium or potassium hydroxide; the crystals of benzidine with half a molecule of ether which form on cooling are separated, dried and heated to 100 DEG  C. in an atmosphere of hydrogen, when pure ether distils off and is collected.

Abstract: 437,941. Goods-receiving devices for houses &c. CROWE, G. E. W., 242, Tottenham Court Road, London. July 3, 1935, No. 19048. [Class 18] [See also Group XXV] Apparatus for receiving goods at houses &c. comprises a rotatable receptacle 3 and an outer door 7 whose fastening is rendered operative after the goods have been inserted and the receptacle rotated, so that after the door has been closed, it cannot be opened from outside. As the receptacle is rotated, a pin 12 projecting from the base plate thereof presses on a pivoted lever 9 which in turn actuates a further pivoted lever 18. The latter lever is connected to and causes a bolt 14 to project whereby, when the door 7 is closed, it becomes locked in position. The pin 12 subsequently engages a recess 13 in the lever 9 and prevents the receptacle being rotated or the door unlocked until the apparatus is released through the inner door 8 of the outer casing. The lever 18 carries a pin which engages in a slot in the bolt, and the pin and the inner end of the bolt are connected by a spring. There is a pin-and-slot connection between the levers 9, 18 and the lever 9 is also acted upon by a spring 10. The receptacle 3 is compartmented and comprises a cylindrical member with openings 5. The bolt may be shot by an electromagnetic device acting on either of the levers 9, 18.

Abstract: 887,771. Drying articles. FAN SYSTEM S Ltd. June 7, 1960 [June 6, 1959], No. 19430/59. Class 34(2) In a method of drying articles, e.g. unbaked bricks, air is blown over the articles by one or more fan or blower units which travel to and fro along an overhead support from which they are suspended, the traverse movement being obtained from a constantly rotating motor on one or more of the units driving a sprocket which engages a complemental double-sided toothed member on the support, the motor being mounted for movement about a vertical axis and being caused to swing about the axis at the end of each movement along the support to transfer the sprocket from one side of the toothed member to the other. Each fan unit comprises a fan casing 52, Fig. 8, having a fan motor and fan 29, 30, which casing is adapted at its top for suspension from a wheeled carrier 28. The carriers are connected together in tandem by rigid links so as to be reciprocally driven along an overhead mono-rail 26 in a drying chamber 1, Fig. 2, in which the bricks are either stacked in bays or positioned in wheeled trucks by means of a non-reversible driving motor 38 mounted by a frame 39 on the carrier at one end of the line of carriers. The motor 38 drives a sprocket 41 which meshes with a roller chain 43 secured to the underside of the monorail to move the fan units and the frame 39 is pivotally mounted about a vertical axis so that the sprocket is switched around the end of the chain at the end of a traverse to travel along the other side of the chain. The pivotal movement is caused by contact of a bolt 49 on the frame 39 engaging a V-shaped part 45 of a spring stop member mounted at each end of the monorail. The fan units circulate flue gases from a kiln and/or heated air from trunking 12, 13, 14 throughout the drying bays either by extending downwardly between adjacent rows of bricks so that the air is discharged through outlets 54 laterally towards the bricks, or the units are positioned above the bricks to direct the air downwardly on to the bricks.
