Title: Improvements in signalling devices for aircraft
IPC: B64D45/00
Filed: 1959-05-15
Abstract: 880,303. Discharging from aircraft. ENERUD, O. C. May 15, 1959 [June 3, 1958], No. 16808/59. Class 9(2). Indicator discs 25 to be dropped from aircraft are stored in containers 16 supported in the fuselage by brackets 23 and connected by cables 18 to handles 17 associated with inscribed plates 37, so that a pilot may select the appropriate discs to release as an indication of the nature of a mishap to the aircraft. Latches 27 projecting through slots in the containers bear against a support plate 26 to retain the discs. The latches are carried by levers 34 pivoted on the containers and secured against rotation by a cap 36 fitting over the free ends of the levers and connected to the cable 18. Operation of a handle 17 tensions the cable and withdraws the cap 36. The levers, thus freed, no longer resist the pressure on the latches due to a spring 31 bearing against a follower 33 placed over the discs 25. The latches therefore rotate out of engagement with the plate 26 and the discs are thrust out of the container, the mouth of which is flush with an opening in the fuselage.

Title: Free-wheel drives for motor vehicles
IPC: F16D41/00
Filed: 1932-06-15
Abstract: 395,861. Free-wheel clutches. HARDY, SPICER, & CO., Ltd., HARDY, E. J., HARDY, J. L., and DANIELL, J. A., Birch Road, Witton, Birmingham. June 15, 1932, No. 16862. [Class 80 (ii).] In a free-wheel driving device adapted for bidirectional driving below a predetermined speed, bidirectional driving is facilitated by a toothed member 13 mounted on the hub 2 and co-operating pawls 19 mounted on the driven member and adapted to respond to both gravity and centrifugal force. The pawls 19 are freely mounted on bolts 20 which bolt together rings 4, 5, 6 surrounding the hub, the outer rings 4, 6 respectively comprising an oilretaining device 8 and a support for a ball bearing 9 while the inner ring 5 forms the outer member of the ball or roller free-wheel and a support for the ball bearing 10. The rollers 11 of the free-wheel clutch are supported on an inner ring 12 provided with the usual inclines and shoulders, the clutch being arranged to overrun when the driven shaft 7 runs faster than the driving shaft. When forward drive is effected, the hub rotates clockwise and the drive is taken up by the resulting wedging action of the rollers 11. Above a predetermined speed the pawls 19 are withdrawn from the ratchet teeth under centrifugal action and overrunning may be obtained. When starting the vehicle in reverse gear, the hub 2 is rotated anticlockwise and the drive is transmitted through the ratchet and the upper pawls. The teeth of the ratchet are slightly undercut so that in reverse drive there is a tendency for the pawls to remain in engagement. Specification 383,701 is referred to.

Title: Improvements in Sealing Strips.
Inventor: BRIGHT ROBERT GRANVILLE
IPC: B60J10/00
Filed: 1966-04-20
Abstract: 1,182,244. Sealing strips. DRAFTEX Ltd. 10 April, 1967 [20 April, 1966], No. 17343/66. Heading B5K. [Also in Divisions El and E2] A sealing strip for mounting on a supporting flange comprises a clip and a covering therefor, the clip being constructed from a blank of suitable sheet or strip material, for example, mild steel or aluminium, the blank being slotted or slit and stretched so that the clip has two series of longitudinally spaced limbs, the clip being of substantially keyhole cross-sectional form, the limbs being cranked intermediate their depth to provide oppositely positioned inwardly directed gripping portions for directly or indirectly gripping the flange. In the construction shown in Fig. 1, the gripping portions press limbs 7 of a covering into contact with the flange 4, but in a modification, the limbs 7 of the covering do not extend so far into the interior of the clip so that the clip grips the flange directly. The lower parts 5 of the limbs of the clip below the cranked portions diverge to provide a lead-in to facilitate pressing the clip and its covering on to the flange. In one construction, the limbs are formed by slotting the blank alternately from opposite edges, in another form the blank is slit alternately from opposite edges and is then stretched lengthwise so that the slits become V-shaped slots. In a third form the blank is formed with slits which project inwardly from opposite edges of the blank and with slits intermediate the firstmentioned slits and having a length less than the width of the blank; the blank is then stretched lengthwise to cause the slits to open out respectively into V-shaped slots and diamond-shaped slots. The clip can be wholly enclosed in a strip of rubber or plastics material by extruding the strip over the clip.

Title: Method of producing nonageing extra deep drawing cold-rolled steel sheet
IPC: C21D8/04
Filed: 1965-04-26
Abstract: Molten steel containing 0.06-0.12%C and 0.03-0.05%O is prepared in an open hearth furnace or converter.  After tapping the steel is subjected to a vacuum treatment to effect deoxydation and decarburization so that the degasified steel contains 0.03-0.10%C and below 0.020%O.  A deoxidizing agent such as Al may also be added in small amounts.  Boron alloy, e.g. ferro boron, is added in such amount that its content totals 0.003-0.010% and the molten steel is then cast into an ingot, which is subsequently rolled and coiled. The coil is bright annealed at a temperature of 650-750 DEG C. in an atmosphere containing wet hydrogen of dew point 20-30 DEG C., e.g. 0.05 vol. % CO2, 0.05 vol. % CO and 3-10 vol. % H2, the remainder being N2, whereby the carbon content of the steel is finally reduced to below 0.005%.

Title: Improvements in or relating to the manufacture of vacuum tubes
IPC: H01J5/20
Filed: 1943-10-22
Abstract: 573,999. Vacuum tube envelopes. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and POWERS, S. J. Oct. 22, 1943, No. 17424. [Class 39 (i)] [Also in Groups XI and XXIII] Portions of the envelope of a vacuum tube which are of dielectric material are sealed together by applying a high-frequency potential across the joint to cause dielectric heating. As shown in Fig. 1, the glass envelope 1 of a tube is formed with a fluted flange 7 which rests on a glass dish-form base member 2 carrying the electrode structure and supported by a copper cylinder 8, the whole being contained in an evacuated bell-jar 9. A highfrequency potential is applied between this cylinder and a split copper ring 10 surrounding the lower part of the envelope 1, causing the flanges 6, 7 of the base member and envelope to melt and run together. Exhaustion of the envelope, which occurs through the spaces formed by the fluted flange 7, is assisted by heating the electrode structure by current supplied through terminals 18. In a modification, the electrode leads are brought out radially through the flutings of the flange 6, and become sealed into the joint. Fig. 4 shows a modification in which the envelope is formed with a fluted flare 21 which is sealed to an upstanding flange 22 on the base. A copper disc 23 serves as one of the electrodes for the high-frequency potential, and serves in the finished tube as a shield between the lead-in wires, which may be sealed between the flanges 21, 22 or pass through the disc 23 and base 2. An extension 24 from the copper disc may serve as a locating pin. In a further modification, Fig. 6, the lower end 25 of the envelope is chamfered and supported on glass wedges 27 located in a groove in the glass or ceramic base. Specification 474,706, [Group XXXVI], is referred to.

IPC: H04L21/04
Filed: 1966-04-21
Abstract: 1,109,342. Electric selective signalling. TELETYPE CORPORATION. 21 April, 1966 [21 April, 1965], No. 17470/66. Heading G4H. In printing apparatus in which each character is formed by a sequence of dots an output representing each dot of the sequence is utilized to determine the position of the next dot. In the embodiment described each code input on parallel lines is applied with its complement to two sets of AND gates 83, 84 (Fig. 2) one of the gates in each set being enabled to pass a signal through amplifiers 65, 66 to mark one of the output leads from a diode matrix 15. If however the input represents a machine function, e.g. spacing, line feed, bell or carriage return one of the AND gates 11, (Fig. 3) is enabled to control the printer and also via an OR gate 45 to inhibit a gate 17 and prevent clock pulses from a terminal 13 being applied by a lead 67 (Figs. 2 and 3) to enable the second set of amplifiers 66 and hence disenable the diode matrix 15. Each output lead from the diode matrix threads the cores in a dot core array 16, (Fig. 8) which represent the associated letter. At the beginning of a cycle a reset pulse is applied on wires which thread all possible first cores of a letter the single core which is thus reset inducing pulses on whichever of the wires 92-98, Fig. 8, thread it. The pulses on the wires are applied via shift registers (110, 160, Fig. 4, not shown) to analogue-digital converters (208, 211, 212, 213, Fig. 11, not shown) to control respectively the horizontal and vertical plates of electrodes directing the jet of ink, the binary bits representing the horizontal deflection being preferably temporarily stored in a shift register (200, Fig. 4, not shown) so that the vertical deflection is applied first. The outputs from the second shift register (160) are also applied to two further sets of AND gates (181, 182, Fig. 5, not shown) to mark one output lead from a further diode matrix (21) this output controlling which core in the dot core array (16) should be reset next. All cores which may represent the last dot of a character have a further lead (221, Fig. 4, not shown) threaded through them so that when the last core is reset a spacing pulse is applied to the printer.

Title: Silica sols
IPC: C01B33/141
Filed: 1965-04-27
Abstract: A stable alkaline SiO2 sol is made by removing water from an alkaline SiO2 sol which initially contains 5-35% wt. colloidal SiO2 particles of a size in the range 15-75 mm . The initial liquid medium comprises water, a mineral acid salt (1) and a salt (2) consisting of a metal cation and a silicon oxide-containing anion.  The resulting sol contains 39-52% wt. of the colloidal SiO2 particles and the aqueous phase contains 0.055-0.095 equiv./litre of the mineral acid salt 1 and 0.01-1.0% wt. of the liquid phase of the salt (2).  This resulting sol also has a pH of 8.8-9.9, a viscosity below 85 centipoise at 25 DEG  C., a SiO2:M2O ratio of 75-350:1 and a specific conductance of 5400-6800 m mhos at 25 DEG  C.  Salt (1) can be an alkali metal chloride, sulphate, nitrate, phosphate or carbonate. Salt (2) can be an alkali metal silicate, e.g. sodium or potassium silicate with an SiO2:M2O ratio of 1 to 3.6:1.  The water can be removed by evaporation or distillation.  The initial SiO2 sol can be made by adding an acidic silica hydro-organo-sol, containing a 4-12% wt. SiO2, (b) an organic liquid of b.p. > 100 DEG  C. and (c) 0.01-0.4% wt. of mineral acid salt (2), to an aqueous alkali metal silicate solution containing 0.5-2.5% wt. SiO2 and of pH 10.5-11.3 at 25 DEG  C. at a temp. high enough to distil off the organic liquid. The organic liquid of the sol can be ethanol, isopropanol, t.-butyl alcohol, acetone or methyl ethyl ketone.  The hydro-organosol may be made by forming an acidic sol, pH 1.8-4.5, of an acidic alkali metal silicate by the addition of an acid, e.g. H2SO4, and organic liquid to an alkali metal silicate at a temp. preferably between - 20 DEG and + 15 DEG  C. The sol can be cooled and filtered or centrifuged. The salt concentration of the hydro-organosol can be reduced 0.01-0.14% wt. using an ion-exchanger.  Alternatively the hydro-organosol can be made by de-ionizing the sol to a residual salt content below 0.1% wt. and then mixing the resultant liquid with more unde-ionized or partially de-ionized sol.
