Title: Improvements relating to the preparation of gypsum plaster
IPC: C04B11/036
Filed: 1958-12-22
Abstract: An apparatus for burning gypsum comprises an externally heated treating zone containing grinding means, inlet and outlet means, means for continuously supplying raw gypsum to the zone, and means for passing a heated gaseous medium through the zone in the same direction as the gypsum.  The treating zone may conveniently be a drum, containing balls or other grinding elements, with axial inlet and outlet apertures, surrounded by an enclosure <PICT:0872269/III/1> <PICT:0872269/III/2> <PICT:0872269/III/3> through which hot gases pass to heat the drum, said gases optionally being recycled through the inside of the drum.  Means for passing some or all of the gypsum through the heating enclosure may be provided, such as perforations in the drum wall and/or screw conveyers passing through the enclosure.  In the apparatus illustrated in Fig. 1, raw gypsum is fed from hopper 1 via shoot 3 and screw conveyer 4 into a rotating drum 6, of which the interior is divided into compartments by means of perforated walls 8, each compartment containing grinding elements, the fineness increasing from one compartment to the next. Surrounding drum 6 is an enclosure 12 in which there is a partition 13 reaching to the drum 6, thereby dividing the enclosure into chambers 14a, 14b joined by gap 14c (see Fig. 2).  A burner 15, preferably for liquid fuel, is mounted in the chamber 14a.  The combustion gases are sucked out via conduit 16 to stack 18, and a portion are withdrawn via conduit 20 to be cycled to the interior of the drum.  A portion of the partly calcined gypsum may be introduced into the enclosure 12 via gratings 8b, and are there superfired, being protected from the direct flames of the burner by a transverse wall 14d.  The product from the drum is withdrawn via outlet 11 and conduit 21a.  In the modification illustrated in Fig. 3 (and Fig. 4, not shown), a portion of the calcined material issuing from 21a is fed into the enclosure by means of conveyer screw, and is then withdrawn to hopper 36 by a screw revolving in the opposite direction.

Abstract: 413,622. Fare-ticket printing and issuing device. CZERWENY, V., 12, Hallerschlossstrasse, Waltendorf, near Graz, Styria, Austria. Oct. 12, 1932, No. 28411. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 15, 1932]. [Class 106 (iii).] A ticket printing and issuing device particularly for use on vehicles has a fare printing member set consequent on the setting of starting and arrival station printing members. The arm 1 is positioned opposite the station on the scale 41 to bring the appropriate type on the disc 3 to printing position opposite the printing plate 20. The arm 2 is likewise set opposite the arrival station to bring the appropriate type on the disc 4 tc printing position. The setting operations of the discs 3 and 4 sets through differential gearing 5, 6, 7 the disc 8 which through bevel gearing 9, 10, 11 rotates the shaft 12 to rotate the fare printing drum 14 to bring the fare type to printing position that corresponds to the angle between the arms 1 and 2. A printing drum 13 is simultaneously set for printing on a checking strip. The ticket strip passes from the roll 21 over the printing plate 20, between the rollers 24, 25 to the aperture 40. The checking strip passes from the roll 27 over the printing plate 20 to the roll 28. The ink ribbon 29 passes from a roll 30 over the printing plate 20 to the roll 31. To print the lever 19 is raised to force the printing plate 20, ticket strip, and checking strip against the printing drums. On the downward movement of the lever 19, the click-wheel 23, gear 44 and rollers 25, 24 are driven to feed the ticket through the aperture 40, the ticket being severed by the knife 26 cutting across perforations in the strip. An indicator drum 15 visible from the outside through the aperture 45 and set by the strap 32 from the shaft 12 shows the fare to be printed. For printing additional fees the handle 36 is rotated to set ticket strip printing drum 34, checking strip printing drum 33 and indicating drum 35. It is stated in the Specification that the type discs and printing drums can be replaced by shiftable matrices in a straight line ; that the differential gearing for setting the fare printing drum can be replaced by a coupling mechanism which only comes into action when the setting of the arrival station oversteps the setting of the starting station ; that the scale 41 can be used for different lines ; that the printing of the different characteristics can take place successively instead of simultaneously, e.g. by having all the printing members in one rotatable printing drum, the printing of the arrival station and the fare taking place simultaneously ; that the device can be adapted for printing tickets for return journeys; and that additional devices, e.g. a time-stamp, a counter for numbering the tickets, and a total fare counter, may be provided which can be built in the printing- plate.

Filed: 1975-10-16
Abstract: 1485687 Electron beam devices; lasers HUGHES AIRCRAFT CO 16 Oct 1975 [7 Nov 1974] 42460/75 Headings H1C and H1D In a flowing gas laser excited by the combination of an electron beam and an electrical discharge within the gas as described in Specification 1,485,538, the electron beam distribution is profiled in the direction of gas flow so as to have minimum intensity at the extremities of the excitation region and maximum intensity adjacent its centre. As shown in Fig. 6, gas flowing through an excitation region 26 in a duct 24 is excited by an electron beam from the cathode 160 of an electron gun 28, the beam passing into the duct through a window 108 formed by a metallic, e.g. titanium, foil 130, Fig. 7, bonded to a multiapertured stainless steel member 110. The window serves as an anode for the electron gun and as an electrode for a gas discharge extending across the duct from an electrode 112. The graded distribution profile of the electron beam intensity may be obtained by shaping each aperture 144 in the window member 110 so that its width in the direction of gas flow is tapered from a maximum value in the centre as shown at 244 in Fig. 12. Alternatively the apertures 144 may be like rectangles as shown in Fig. 9, and the grid electrode 168 of the electron gun formed by parallel bars tapered with increased width from the centre as shown at 368 in Fig. 13.

Title: Cattle grids and like barriers
IPC: A01K3/00
Filed: 1960-12-14
Abstract: 960,157. Cattle grids. P. D. C. WALKER. March 8, 1962 [Dec. 14, 1960], No. 43097/60. Heading E1G. A cattle grid comprises two grills formed of resilient metal rods 10 hinged about a rod 14 and is normally supported with the rod 14 at the apex of a triangle formed with the ground by a cord 23 and pulley 25 housed in a pillar 16 at each side of the grid. The end of the cord is secured to a bar 25 passing through the lower end of a weight 27 slidable within the pillar. A flap valve 29, which may have small apertures through it, closes the lower end of the weight. Oil is introduced through a cap 30 into the pillar, filling an aperture 28 through the weight 27 and extending up to a normally closed overflow opening 31. When a vehicle is driven on to the grid, the individual rods 10 actually beneath the wheels are first pressed down on to the ground, and then the grills as a whole, the weight 27 rising readily within the pillar 16 due to the opening of the valve 29. When the vehicle leaves the grills and the weight starts to descend, the valve 29 closes retarding the descent, the speed of which is dependent on the viscosity of the oil, the fit of the weight within the pillars and the size of any apertures in the valve 29. Springs 33, tending to raise the rod 14 but not strong enough to do so while the grid is lying flat on the ground, may be provided. The rod 14 can be disengaged from the hooks 24 securing it to the cord 23 and the grid dropped flat on the ground. In alternative embodiments, non resilient grill elements are spring-mounted at their ends.

Title: Tube reducing apparatus
IPC: B21D22/16
Filed: 1965-10-12
Abstract: 1,087,207. Rolling tubes. CONTINENTAL TITANIUM METALS CORPORATION G.m.b.H. Oct. 12, 1965 [Oct. 12, 1964], No. 43251/65. Heading B3M. Apparatus for reducing the diameter and/or wall thickness of a tube 18 comprises a base 10, a working head 12 clamped to the base, and two movable carriages 14 and 16 for gripping the ends of the tube and drawing it through the head, the speed of the carriage 16 being controlled in response to back tension created in the tube by the carriage, in order to maintain the back tension constant. The drawing tension produced in the tube by the carriage 14 causes stopping of the carriage if the tension exceeds a sate value. Spring-loaded rollers 26 support the tube during working. The head 12, Fig. 3, includes a base 32 on which a motor-driven rotatable frame 34 is supported by bearings 36 and 38, annular working tools 64 and 66 being carried within the frame. The tools are freely rotatable in eccentrically mounted bearings 56 and are progressively moved around the circumference of the tube by rotation of the frame. A plain mandrel when used within the tube gives rise to a reduction in the wall thickness of the tube, while a stepped mandrel 19, Fig. 6, produces a tube of smaller internal diameter. Each tool is positioned within an adjusting ring 52 which has an internal bore in eccentric relation with its outer surface. Angular adjustment of the ring within the frame 34 thus alters the eccentricity of the appropriate tool relative to the axis of rotation of the frame, and allows control of the workpiece diameter. Rotation of a wormwheel which co-operates with the toothed outer surface of each ring causes angular movement of the ring, a differential assembly 70 permitting adjustment during the reducing process and thereby allowing tapering of a tube. Each differential assembly, Fig. 3, has two input gears 100, 106 the gear 100 being connected through a pinion 98 with an annular 94 keyed to the rotating frame 34. The gear 106 meshes by way of two pinions with a further annulus 96 which is keyed to a cylindrical member 86, meshing in turn to a pinion 78, gear 84, and bevel gears 74, 74a. The adjusting worm which co-operates with the appropriate ring 52 is driven by bevel gear 74. Normally the differential ensures that no adjustment of the worm takes place, but rotation of a shaft 132 moves a carrier 110 to produce such an adjustment. The shafts 132 are rotated hydraulically by means of a motor 134, Fig. 11, under the control of a four-way valve 136. Further hydraulic motors 144, and 186 control the movements of the two carriages. Pistons 182 connected to a gripper 140 for the carriage 16 move in response to back tension changes exerted by the gripper, and thereby influence a variable orifice valve 200 by means of a cam 196 to control the speed of a motor 144 and maintain the back tension constant. A similar set of pistons 182 for the carriage 14 serve to stop the respective motor 144 to halt the carriage, in the event of the drawing tension being too great.
