Title: Improvements in or relating to the manufacture of fiber optical light-conducting devices
Inventor: WOODCOCK RICHARD FORREST
IPC: C03B37/15
Filed: 1965-09-03
Abstract: A method of making fibre optical devices, e.g. a light-conducting face-plate, having spaced light receiving and emitting opposite end faces of large surface area formed from a number of multi-channelled light conducting structures of a polygonal cross-section composed of a multiplicity of glass clad glass light conducting fibres fused together in side-by-side prearranged geometrical relationship, each multi-channelled structure being equal in length to the distance between the opposite faces of said plate, comprises bundling said multi-channelled structures together in side-by-side relation with each other in such manner that the spacing therebetween is substantially no greater than the distance between their respective fibre elements, heating the bundle to fusion temperature and applying a radially inwardly directed compressing force substantially uniformly over substantially the entire length of the bundle to hermetically seal respective components of the assembly to each other and to render the resulting plate structure as a whole substantially impervious to air and gases.  A number of fibres 20 (Fig. 3, not shown), having a glass cladding of lower refractive index than the fibres, are placed in an hexagonal channel in a mould not wetted by fused glass.  The mould is heated in an electrical furnace to fuse the fibres to form a multichanelled structure 32.  One end of this structure is then sealed in a member 52 (Fig.5 not shown) said member being held in a vertically movable clamp and being connected to a vacuum source.  An annular heating element 60 is fixed around the now lower end of the structure 32.  The structure is heated to softening point and simultaneously drawn downwards to form an elongated fibre structure 66 which is then divided up into light conducting elements 26 of the length desired for the face-plate. A plurality of these members 26, which are still hexagonal, are then placed in a glass ring member 68, the depth 70 (Fig. 7, not shown) of which represents the thickness of the face-plate. A steel band 78 (Fig. 9, not shown) is placed around the ring 68 and one end of the band is fixed to a stationary part 86 of a member 72, and the other end fixed to a rod 97 which is caused to move away from said fixed end by a compression spring 98.  The assembly is heated to fusion temperature in a furnace the action of the band radially compressing the glass structure to cause the elements to hermetically seal to each other and to the ring to form a face-plate. The compressive force of the band 78 can be adjusted by controlling the compression of the spring 98.  In an alternative method the members 26 are placed into a desirably shaped cavity between two blocks 136, 138 (Fig. 12, not shown) which can slide over a mica covered base 144 in a channel 134 in a member 130, the blocks being urged together by a spring 148.

Title: A ground vehicle attack system
IPC: F42B23/04
Filed: 1963-10-04
Abstract: 1,059,356. Hollow charges for land mines. BOLKOW G.m.b.H., and F. R. THOMANEK. Oct. 4, 1963 [Oct. 4, 1962], No. 39188/63. Heading F3A. A hollow charge (1), Fig. 1 (not shown), for use against ground vehicles, the charge being triggered off by the proximity of a target, is housed in a thin-walled tubular container 2 together with an electric ignition device 4. During transport the container also houses signal receiving means 5, the container being closed by a cover (6). Fixed to the container is a tripod mounting 11, 12, 13 by which it can be set at a height of one to one-and-a-half metres above the ground with the longitudinal axis parallel to the surface. The charge can be aligned with a target by means of a sighting device 14, 15. A conductor 10 connects the device 4 to an igniter (9). After placing the container 2 in position, the device 4 and means 5 are placed on the ground. The means 5 may comprise perforated insulating strips separating metal foils housed in tubes of insulating material, the tubes being placed parallel to the longitudinal axis of the container, so that when a vehicle moves over the tubes, the foils are pressed into contact and a circuit is closed in the device 4 and fires the igniter (9). The distance between the leads 5 is chosen to correspond with the size of the target and the charge (1) is only detonated when the target moves over both leads. The device 4 includes a safety switch and a time switch so that the charge is armed a given time after setting. Instead of the leads 5, the target may intercept a light beam arranged as in Fig. 4 (not shown), where a light source (25) is placed between a reflector (26) and a lens (27). The beam (28) issuing from the source (25) is reflected by a mirror (29) to a receiver (30) connected to the device 4. If a vehicle interrupts the beam between the mirror (29) and the receiver (30), the ignition circuit is closed as before and the charge (1) is fired. Instead of a light beam, a radar system, Fig. 5 (not shown), may be employed, the charge being fired when the radar signals are reflected by a vehicle (37). When the charge (1) is detonated a metal liner (8), fitting the forward cavity (7), collapses and forms a slug, which is said to penetrate the vehicle under attack.

Title: Line pressure modulating device for an automatic power transmission
IPC: F16H61/08
Filed: 1973-08-20
Abstract: 1386568 Change-speed control NISSAN MOTOR CO Ltd 20 Aug 1973 [24 Aug 1972] 39193/73 Heading F2D In an hydraulic control system for an automatic power transmission system for a vehicle, line pressure modulating means are provided for reducing hydraulic pressure so that a gear may be engaged without shock when the vehicle is stationary. In the system shown, an hydraulic line 12 having connections 26, 28, 32 with a line pressure regulator valve 24 connects a pump 10 with a manual selector valve 14 which in turn communicates with a shift valve 18 having a connection 20 to an actuator 22 for a transmission friction element, e.g. a brake or clutch. During normal operation a movable spool 52 of the valve 24 is acted on in one sense by line pressure admitted through a restriction 32a and in the opposite sense by a spring 66 and pressure from a valve 46 admitted through a port 36 to differential lands 56, 58 whereby the spool adjusts an escape passage 28, 40 so as to maintain line pressure at a value related to the pressure from the valve 46 which is responsive to engine throttle opening. When reverse drive is selected the valve 14 directs line pressure to a port 34 to give additional bias to the spool 52 to provide a higher line pressure. Release of the accelerator pedal closes a switch 116 to cause a solenoid 112 to move a control valve spool 104 to the left so that line pressure from a connection 102 of the valve 14 is communicated through ports 96, 98 to a port 72 and thence, provided the vehicle is stationary, through a port 76 to a port 30 where it acts on differential lands 62, 64 to reduce the line pressure. When the vehicle is in motion the valve spool 84 is urged to the left by pressure from a governor valve 82 responsive to transmission output shaft speed so that the port 30 is isolated from the port 72 and vented to a port 74. In a modification a kickdown valve, displaceable in response to the output pressure from the valve 46, is interposed in the conduit 92 between the spools 84, 104, and a second switch is operable by the accelerator pedal so that the spool 104 is displaced to the left on kickdown, and the kickdown valve then diverts the pressure fluid in the conduit 92 to the shift valve.

Technical magnesia is manufactured by caustic calcination of a magnesite of suitable SiO 2  and Al 2 O 3  content and subjecting it to the action of hydrogen chloride gas, in the absence of combustible or reducible gases, at a temperature between 800‹ and 1100‹ C., iron and manganese being converted to volatile chlorides, whilst calcium is converted to its chloride which remains in the material to give an intermediate product which by a post-treatment of the residual chlorides is converted to technical magnesia of the desired final composition and at least a part of the hydrogen chloride used is recovered from the volatile chlorides. Products of the process which are practically free from iron and manganese may be (a) more than 97% by weight MgO with SiO 2  and CaO, (b) more than 94% by weight MgO with CaO and SiO 2  less than 5% by weight in a weight ratio either greater than 2 to 1 or less than 1 to 1 respectively. The CaO and SiO 2  content is preferably less than 4% by weight. The post-treatment comprises an oxidation of the residual chlorides by means of steam. The amount of calcium in the product may be regulated by leaching out a part or all of the calcium chloride present prior to the steam oxidation. The recovery of hydrogen chloride is carried out using known methods.

Title: Process for recovering platinum group metal values from composites containing the same
Inventor: PULLEN JOSEPH BONNETTE
IPC: C01G55/00
Filed: 1958-12-08
Abstract: Arsenic - contaminated platinum - containing catalysts, and other composites containing platinum with arsenic contaminants, are treated to remove the arsenic and recover the platinum group metal values, by forming a solution of the composite and distilling the solution in the presence of added hydrochloric acid and a ferrous salt, whereby the arsenic is volatilized.  The invention is particularly useful to the recovery of platinum values but is applicable to the recovery of palladium, iridium, rhodium, rhenium and ruthenium.  The initial solution is normally formed with aqua regia.  Platinum group metal catalysts, normally containing an inorganic oxide carrier such as alumina, silica, zirconia, magnesia, titania, thoria, boria or strontia or mixtures thereof are preferably first freed from substantially all carbonaceous contaminant by oxidation and the carrier material is then dissolved with an inorganic acid, particularly sulphuric acid of 25 to 90% strength.  The dissolution of the carrier is facilitated by increased pressures.  The platinum- and arsenic-containing insoluble sludge is then dried and if necessary oxidised to remove residual carbon, and then taken up in aqua regia, preferably with a hydrochloric/nitric acid ratio of 3 to 1, at a temperature of 65 to 93 DEG C. and if desired under super-atmospheric pressure.  The solution is filtered and distilled at 98 to 178 DEG C. in the presence of hydrochloric acid supplied in a concentration of 20 to 90% and of ferrous salt which may be the chloride, bromide, fluoride or sulphate, added as such or an aqueous solution in an amount equivalent to at least 2 and preferably up to 4 atomic weights of iron per part of arsenic. The hydrogen chloride addition is made at the rate at which the overhead distillate is collected.  After arsenic has been removed, excess hydrochloric acid is recovered by evaporation and the resulting arsenic-free solution of, for example, chloroplatinic acid, may be employed to produce new catalysts.  Elemental platinum may be recovered from such concentrated chloroplatinic acid by precipitating with hydrazine hydrochloride, hydroquinone, formaldehyde, catechol or an aminophenol.  The chloroplatinic acid may also be purified by precipitating the platinum and redissolving in aqua regia or by subjection to ion exchange.
