Title: Electrlytic drilling of branches from passages
IPC: B23H9/16
Filed: 1970-08-27
Abstract: 1363846 Electrolytic machining of passages DEFENCE SECRETARY OF STATE FOR 26 Aug 1971[27 Aug 1970] 41357/70 Heading C7B  A lateral branch 16 is electrolytically drilled from a passage 4 in a metal workpiece using as tool a tube 8 of insulating material which contains a wire electrode 12, is formed with one or more holes in its sidewall, and which makes a clearance fit in the passage 4, whilst supplying electrolyte to the bore of the tube under pressure such that a jet of electrolyte emerges from the hole(s) in the tube and impinges on the passage wall. The tube forming the body of the tool may be of fused quartz; and the electrode 12 may be formed by a wire or by a gold deposit on the internal wall of the tube. To limit variation in current intensity during operation the wire electrode may terminate short of the highest hole in the tube, the wire electrode may be coated with insulation (50) in the neighbourhood of the holes Fig. 4 (not shown) or the tool may traverse the passage laterally during operation towards the passages being formed. To concentrate electrolyte flow, the holes may be lined with capillary glass tubes which extend outwardly from the tool tube 8 Fig. 5 (not shown). In the production of turbine blades the present method may be used to provide lateral passages to connect cooling passages running adjacent the leading edge of the blades. In the tool used therefore the holes may be formed in a partial helix about the tube; and the tool may be positioned in operation such that the lateral passages formed do not lie on a plane through the axes of the cooling passages connected thereby Fig. 6 (not shown) thus imparting a swirling motion to cooling air subsequently passed therethrough. The tool and workpiece may be mounted in a jig provided with means for producing relative movement between the tool and the workpiece in both lateral and axial directions, and to provide rotation of the workpiece, Fig. 1 (not shown).

Title: Improvements in and relating to stabilising devices for bodies located in a channel or bore
Inventor: BRYANT TERENCE GRAHAM
IPC: G21C3/12
Filed: 1961-11-24
Abstract: 958,903. Fuel elements. NUCLEAR POWER PLANT CO. Ltd., and A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. Dec. 14, 1962 [Nov. 24, 1961], No. 42054/61. Heading G6C. A stabilizing device for a fuel element or control rod located in a moderator channel having a fluid flow therein prevents flutter of the fuel element due to said fluid flow by means of radial arms of aerofoil foil cross section extending from the device towards the channel wall and arranged so as to produce on the body a resultant lateral or radial force sufficient to overcome any disturbing forces which might cause flutter. As seen, the device is mounted on the end of a helically finned fuel element, and comprises two fins 3, 4, of aerofoil crossed section arranged to give a linear resultant force in direction C; a third fin 2 of aerodynamically neutral cross-section acts as a spacer. The conical recess 1a (see also Fig. 2) provides a self centring seating for the fuel element above, if a plurality of elements are to be loaded in the same vertical channel. In a second embodiment (Fig. 3, not shown) four fins of aerofoil cross-section are radially positioned about the body 1 in such a way that they each have a major reaction component acting in a common direction. The aerofoil section fins may be attached to the body of the stabilizer by screws in such a way that the incidence angle of the sections may be pre-set at various angles. It is a feature of the invention that increased fluid flow giving rise to correspondingly larger flutter forces also gives rise to proportionately larger stabilizing forces.

Title: Improvements in the production of thermistor devices
IPC: H01C1/14
Filed: 1963-10-28
Abstract: 1,002,704. Thermistors. W. R. GRACE & CO. Oct. 28, 1963 [Dec. 14, 1962], No. 42490/63. Drawings to Specification. Heading H1K. A process for preparing thermistor devices comprises doping a monocrystalline high purity P-type silicon rod with between 1 and 1500 parts of gold per 10<SP>9</SP> of silicon by means of a zone levelling technique. A rod of silicon having an impurity content of less than 1 part in 10<SP>9</SP> is placed in a zone-melting apparatus together with a P-type silicon seed crystal (resistively 20-50 ohm cm.) and a quantity of very high purity gold. These materials are subjected to a zone melting process whereby a monocrystalline rod of silicon having a uniform distribution of gold (preferably 50- 1000 parts per 10<SP>9</SP>) therein is obtained. The rod is cut into wafers by means of a diamond saw and the resulting wafers are then etched and washed. Aluminium is deposited on to the wafers by means of flash heating in a vacuum (8.5 x 10<SP>-5</SP> mm. Hg). The wafers are then heated in an inert atmosphere (helium, argon or nitrogen) at between 580‹ and 630‹ C. for 20 minutes in order to alloy the aluminium and silicon together, The wafers are etched, washed and then transferred via an ammonium hydroxide bath to an electrodeless nickelplating tank. After deposition of the nickel the wafers are heat treated at 210‹ C. for 18 hours in an argon or nitrogen atmosphere. The wafers are then sliced using an ultrasonic saw and tinned copper leads are soldered to each of the dice. The edges of the dice are ground away to remove any surplus metal which may be short-circuiting the electrodes and to adjust the resistance value to be equal to that of a standard thermistor. The devices are finally painted with a white silicone enamel or with vulcanized silicone rubber.

Title: Improvements in or relating to photographic camera
Inventor: NOACK ROLF
IPC: G03B9/64
Filed: 1965-10-07
Abstract: 1,070,349. Photographic shutters. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Oct. 7, 1965, No.42588/65. Heading G2A. A photographic shutter is provided with a slow speed escapement releasably coupled to a fast speed escapement and with a speed setting member (not shown), the setting of the latter rotating a cam 2 coupled to the driving lever 5 of the fast speed escapement and rotating a shift cam 3 which, in the speed range adjustable only by the fast speed escapement, releases the coupling between the driving segment 6 of the slow speed escapement and the lever 5. When the shutter is tensioned and a slow speed set, the parts take up the position shown. For a different speed the space between the arms 16, 17 of the lever 5 and drive member 18 respectively is different, thus delaying the running down movement of the drive member for a different time. A driving segment 6 connected to a gear retard 12-15 bears against the lever 5 by means of a pin 11. A release member 20 is actuated allowing the member 18 to rotate to release a first locking pawl 22 which thereby frees the shutter opening slide 24 to run down. The arm 17 now strikes the lever 5 which rotates clockwise as shown and drives the gear retard 12-15 through the coupling pin 11. After overcoming the gear retard, the member 18 releases a second locking pawl 23 to release the shutter closing slide 25. For fast speeds, Fig. 2 (not shown), the shift cam (3) is rotated far enough to strike an arm (10) and hence rotate the segment (6) out of contact with lever (5). Hence only the inertia of the driving lever delays the running down of the member 18.

Abstract: 1,154,239. Pipe couplings. GRANVILLEPHILLIPS CO. 24 Sept., 1966, No. 42725/66. Heading F2G. In an ultra-high vacuum pipe coupling a pair of rings 16, 18 secured to pipes 12 and have respectively radially inner and outer cylindrical flanges 16b, 16c, and 18b, 18c axially opposite one another and disposed radially outwardly of the pipes such that when the pipes are clamped together with the flanges 16c, 18c in mutual contact a gap 52 remains between the inner flanges 16b, 18b, and an annular space is defined between the inner and outer flanges. A gasket carrier ring 32 of metal is disposed in the annular space to overlie the gap 52 and a continuous annular, metal gasket 34 e.g. of gold, substantially more easily deformable than the ring 32 is carried on the radially inner surface of the ring to extend into the gap. The thickness of the gasket is such that upon clamping of the rings 16, 18 together the gasket is caused to extrude in the space between the carrier ring and the flanges 16b, 18b, the deformed width of the gasket in the radial direction being at least twice the width, in the axial direction, of the gap. The ring 34 may be rectangular in crosssection and attached to the ring 32 by swaging the ring against the serrated or otherwise roughened inner surface of the ring 32, or circular in cross-section and secured to the ring 32 by soldering, brazing or welding; the gasket may be formed by plating an inner radial flange of the ring 32.

A PNIP or NPIN monocrystalline element for use in a transistor, is formed from a monocrystal doped with a donor and acceptor impurity of which the one determining the conductivity type has the lower diffusion coefficient by bringing it into contact with a molten mass of lightly doped semi-conductor of the same conductivity type. After partial recrystallisation further doping material is added so that the subsequently recrystallizing material is of the same conductivity type but of lower resistivity. During crystallization and, if necessary, in a subsequent heating step, the minor impurity diffuses from the original monocrystal to form a zone of opposite conductivity type in the recrystallized part. The crystal pulling technique may be used or the melt formed on the surface of the monocrystal in an inert gas and recrystallized there. Typically a grown P-type germanium monocrystalline wafer containing 10<SP>18</SP> atoms/c.c. of indium and 10<SP>17</SP> atoms/c.c. of antimony is dipped in a melt of gallium doped 5 ohm cm. P germanium and withdrawn until the recrystallized layer is 100 Á thick when more gallium is added to the melt to provide a zone of 0À005 ohm cm. resistivity. During recrystallization which typically takes 30 seconds a 6 Á thick N layer is formed adjacent the base crystal by diffusion of antimony into the recrystallized region.
