Title: Improvements in or relating to the production of aluminous siliceous material fillers for asphalt or asphalt containing road surfacing materials
IPC: C04B20/06
Filed: 1963-05-23
Abstract: An expanded cellular aluminous siliceous material for asphalt containing road surfacing material is produced by calcining an aluminous siliceous aggregate known to form a lightweight material by expansion at a temperature between that required to convert the aggregate into an artificial pozzolan and its fusion temperature, and thereafter grinding and sizing the product, e.g. so that 12% by weight thereof is retained on a sieve with 0.0017 inch openings.ALSO:An asphalt-containing road-surfacing material is prepared by incorporating in asphalt, with or without mineral filler, an expanded cellular aluminous siliceous material produced by calcining an aluminous siliceous aggregate at a temperature between its artificial pozzolan formation and its fusion temperature and grinding and sizing the product.  The expanded cellular material preferably substitutes equal weights of the mineral filler content.

Abstract: 127,842. Lott, R. E. L. May 26, 1917. Dropping articles from a height.-Petrol tanks carried by aircraft are arranged to be ejected in the event of their catching fire. Figs. 1 and 2 show a petrol tank a having members b secured at each side and hinged to catches c formed with semicircular ends engaging grooves e, Fig. 3, in rotary shafts f. These shafts are held by catches, such as keys g, which may be rotated by levers h so as to release the shafts and catches c and allow the tank to fall. The action of gravity is assisted by springs such as rubber cords k, compressed air, &c., or by the action of the head-wind on a plane m carried by the tank. In a modification, projections at the sides of the tank normally rest on projections on the shafts f. The joints connecting the tank to other parts are constructed so as to be automatically disconnected. The aperture under the tank may be automatically closed after the tank has been expelled. In further modifications, the tank may be supported by a single-point suspension, or by cams engaging recesses in the sides of the tank. Reference has been directed by the Comptroller to Specification 129,369, [Class 4, Aeronautics].

Patent GB-882155-A (GB)
Title: Improvements relating to the production of tubular films of thermoplastic material
IPC: B29C48/10
Filed: 1960-03-04
Abstract: <PICT:0882155/IV (a)/1> In a process wherein tubular film made by extrusion through a die is moved continuously over a mandrel that is in heat-transfer relationship therewith, a layer of gas being maintained between the mandrel and the film, the pressure of gas at all points within a given region is maintained at a substantially constant value by relieving pressure above said value through one or more pressure relief outlets in the mandrel in this region communicating both with the layer of gas and with a zone in which the gas pressure is equal to or less than that desired in the said layer. The constant pressure value may be such that a gas layer not over 10 mils thick and preferably 3-10 mils thick is maintained between the tubular film and the mandrel.  The pressure relief outlets may be in direct communication with the atmosphere.  They may be gas-pervious areas of porous material or annular grooves in the surface of the mandrel.  The mandrel may have gas-pervious porous walls for the passage of gas to maintain the gas layer between the film and the mandrel.  As shown, a continuous tubular film A formed by extrusion through an annular die 11 is passed over an internal mandrel 10 having a porous wall made up of a porous nose section 10a and cylindrical sections 10b, 10c.  The sections are connected by spool-like separators 12, 13 having annular grooves 12a, 13a respectively.  Independent air feed lines 17-19 supply chambers 14-16 so that these may contain air at different pressures.  Escape of gas through the nose of the mandrel is prevented by the closure 20.  The annular grooves 12a, 13a communicate through channels 21, 22 and conduits 23, 24 respectively with the atmosphere or with an enclosed space containing air at a pressure lower than that in the chambers 14-16.  The space 26 within the tubing A between the die and the mandrel is vented by an air pressure relief line 25, to prevent deformation of the still soft thermoplastic tubing by air pressure. The process minimizes or prevents wrinkling and gauge variation of the film.

Title: Improvements in or relating to process for preparing lysergic acid amides and intermediates useful in the preparation thereof
Inventor: PIOCH RICHARD PAUL
Filed: 1955-03-17
Abstract: The invention comprises the mixed anhydride of lysergic and trifluoroacetic acids, and a process (in which it is an intermediate) for preparing lysergic acid amides which comprises reacting lysergic acid with trifluoroacetic anhydride at a temperature below about 0 DEG  C. to produce the mixed anhydride, and reacting this with a nitrogenous base having at least one hydrogen linked to nitrogen. Preferably the lysergic acid is reacted with about two equivalents of the trifluoroacetic anhydride in a diluent inert to the reactants, and the mixed anhydride is reacted with at least one equivalent (e.g. about five equivalents) of the base (e.g. primary amine).  Thus a suspension of dry lysergic acid in acetonitrile may be reacted with an acetonitrile solution of about two equivalents of trifluoracetic anhydride at about -10 DEG  to -20 DEG  C. (e.g. about -15 DEG  C.) and the resulting solution reacted with the base at about room temperature.  In examples the following bases are employed: diethylamine, diethylamino-ethylamine, L-(+)-2-aminopropanol-1 (yielding ergonovine), hydrazine, and ammonia (yielding ergine). Other bases specified are glycine, ethanolamine, diglycylglycine, norephedrine, butanolamine and ephedrine.

Filed: 1971-03-29
Abstract: 1390764 Feeding and delivering sheets VACUUMATIC Ltd and G S DUTTON 28 March 1972 [29 March 1971] 8108/71 Heading B8R Feeding sheets.-Sheets or groups of sheets 20 are separated from the top of a pile 21, Fig. 1, by means of a reciprocating platform 16 having tapered extrusions 17 and a roller 18, which platform is slidable between guide members 15 of a support 13 mounted for vertical movement on a gantry 10. In operation, an angle member 19 is inserted into the pile edge to separate the end portion of the top sheets. The platform 16 then slides under the member 19, which is raised by the extensions 17 so as to form a gap in the pile, into which the platform 16 enters so that the sheets to be separated come to lie on the platform. The member 19 is removed and the platform 16 retracted to a position where the sheets can be pushed on to the table 22 of a handling-machine 23. The support 13 is then lowered by the height of the removed sheets before the process is separated. Delivering sheets.-Sheets or groups of sheets delivered from a handling-machine 23 are received on a table 16, Fig. 2, arranged to reciprocate as in Fig. 1. In this case, the table 16 has a tapered end portion 52. After the platform has carried the sheets to a position over a stack 55, a gate 53 is lowered and the platform is retracted so that the sheets fall on to the stack. Movement of sheets on to the table may be assisted by longitudinal rollers constituting the table surface. After each deposition, either the support 13 is raised or the stack support is lowered, and in the latter case the support is fixedly mounted on the gantry. The surface of the platform may be formed of lateral rollers arranged to rotate while the platform is withdrawn from the stack in such a direction that there is no relative movement between the overlying sheets and the platform surface. Driving-mechanism.-The platform 16, Fig. 3, of both the apparatus of Figs. 1 and 2, is mounted so as to be slidable relative to an intermediate structure comprising a plate 30 at each side of the platform, while the plate 30 is simultaneously slidable in the same direction relative to the member 15, so that the platform 16 moves at twice the speed of the plate 30. A pinion 39 on a shaft 40 supported in a bearing 41 in the plate 30 engages a rack 38 fixed with respect to the member 15 and a rack 37 fixed with respect to the platform 16. For moving the platform, a further pinion on the shaft 40 engages an endless chain which passes round a plurality of guide sprockets mounted on the plate 30 and round a further sprocket rotatable by an electric motor. Alternatively, a pneumatic cylinder is fixedly mounted with respect to the member 15, while the piston slidable in the cylinder is mounted on the plate 30.

Title: Improvements in or relating to sheet conveying apparatus
IPC: B65H29/36
Filed: 1943-05-25
Abstract: 613,804. Feeding and delivering sheets. STEVENS, A. H. (Miller Printing Machinery Co.). May 25, 1943, No. 8318. [Class 100(i)] In a sheet feeding and delivery apparatus means are provided for controlling the operation of the means for the position of sheets on a carrier such as a drop-sheet delivery device. The invention is described in connection with a drop-sheet delivery device as described in Specification 554,109, in which a gripper shaft 23 carrying gripping and sheet-positioning devices 26, 28, 29 as set out in the above Specification is reciprocated by a carrier 4 comprising a pair of brackets 20 connected to reciprocating chains 14 acting in conjunction with belts 3 delivering sheets from a printing or like press. The carrier is fitted with delivery belts 31 passing over rollers 32 and driven by pulleys 34 on a shaft 33 which is driven by a free-wheel drive from a gear which engages a fixed rack 45, so that the belts 31 are rolled from under the sheet as the carrier 4 moves towards the right hand in Fig. 1 to receive a new sheet. The gripper shaft 23 is normally pressed towards operative position in which the grippers hold a sheet by means of a coiled spring 66, Fig. 7, acting upon a sleeve 58 having a radial flange 59 connected by a link 63, Fig. 8, to an arm 60 on the shaft 23. The grippers hold the sheet as the carrier moves to the left, in Fig. 1, and are opened to deliver the sheet as the carriage 4 starts on its return movement by means of the engagement of the adjustable flanges 68, 70 of a roller with a track 52 of triangular cross - section which transmits rotary motion to the sleeve 58 by means of a coiled spring 75 connected at one end to a sleeve secured to the roller 68-70, and wound around the sleeve 58 so as to grip this sleeve frictionally. On the outward motion of the carrier the motion imparted to the spring 75 by the roller 68-70 does not affect the sleeve 58, but on the return movement the spring 75 grips the sleeve and rotates the shaft 23 so as to open the grippers. The shaft 23 is held in the open position of the grippers by a spring-controlled catch, and as the carrier reaches the sheet-receiving position this catch is released by a pivoted detent 87 which exerts effective action on the catch only when the catch is moving towards the right. The detent can move freely in clockwise direction.
