Abstract: 612,074. Making cased tubular rivets. GOODRICH CO., B. F. June 25, 1946, No. 19004. Convention date, July 18, 1945. Drawings to Specification. [Class 83 (ii)] [Also in Group XXV] A cased tubular collapsable rivet is made by forming a rivet member with a shank having a threaded bore and a flanged head at one end and assembling a sheathing member thereover preferably so as to abut the flange. The sheath may itself have a flange and may be in cup form when it is desired to close the shank end of the rivet. The bore is enlarged between the flange and the threaded part to provide a weakened portion to facilitate collapse. The parts may be soldered, brazed, welded or cemented together. The inner member may be machined from bar stock or may be formed from blanks of the shank diameter that are first headed and then drilled and tapped. The sheath may be formed from sheet material by cupping or from tubular blanks by spinning and assembly is effected by forcing the sheath over the rivet. The sheath may be of aluminium or copper alloy and the rivet of stainless steel. Sheaths of rubbery or resinous plastic material may also be employed.

Abstract: 1,089,846. Laminating. HEREFORD TILES Ltd. May 3, 1966 [May 10, 1965], No. 19537/65. Heading B5N. A method of producing tile units, which each comprise a base sheet and a layer of tiles affixed thereto, comprises arranging the tiles 5 in spaced disposition, front face downwards, to form a mould surface on a perforated plate 4 resting removably on the base 3 of a moulding chamber 1, disposing a sheet 6 of plastics material above the tile assembly, thermoforming the sheet 6 to the mould surface constituted by the backs and edges of the tiles by exhausting the air from the chamber through the base thereof to draw the sheet 6 tightly around the backs and edges of the tiles to form individual cells each containing a tile with ribs of the sheet formed between the tiles, removing the moulded sheet with the tiles located in the cells from the perforated plate and, after any necessary trimming of the sheet 6, applying a backing 9, 10 to the sheet to form a piano-surface to the back. In the machine shown, Fig. 1, for carrying out the method the plate 4 has shallow depressions in its upper face to receive the tiles, and the sheet 6, which may be flexible vinyl co-polymer foil, is supported in a frame 7 and softened by an nifra-red heating unit 8 before the tiles are raised to the dotted line position by an hydraulic piston 9 and air is withdrawn from the moulding chamber by an air exhauster 2. After removing the tiles 5 and sheet 6 from the moulding chamber the backing 9, e.g. of polyurethane foam, and optionally a sheet 10 of paper or thin wood veneer, is applied to the sheet 6 using a veneer press. The tiles are secured in the recesses formed in the sheet 6 either by removing them therefrom after the moulding process, applying adhesive to the recesses or the tiles, and replacing the tiles; or by applying a heatactivatable adhesive to the sheet 6 and/or the tiles before moulding; or by forming the tiles with undercut edges with which the sheet 6 interlocks.

Abstract: 297,543. Thomson, T., and Nisbet, N. July 23, 1927. Density separators.-Dust laden gas is cleaned in two separators, the dirty fraction of gas from the first separator being passed to the second. In the arrangement shown in Fig. 1, the separator 2 is of cylindrical form with a tangential inlet 1. Clean air is withdrawn through the flared mouth 3 of the conduit 4 while the dust laden part of the gas passes through the annular space 5 into the second separator 6. The dust collected in this vessel is discharged by the valve 7 and the clean gas is passed through the outlet 8 for further treatment or for return to the inlet 1 of the separator 2. Means may be included in the conduits 4, 8 to ensure the gas travelling with sufficient velocity to obtain efficient operation. In the modification shown in Fig. 2, the first separator 2 is of cylindro-conical form with a central outlet 9 for the clean gas. A conical baffle 11 is placed just below the lower end of this separator and the dirty part of the gas passes over the baffle into the separator 6. Clean air from the space beneath the baffle passes through the outlet 12 and is returned by a fan 13 to the outlet 1.

Abstract: 1,137,633. Flat glass manufacture. PILKINGTON BROS. Ltd., L. A. B. PILKING- TON and G. A. DICKINSON. 26 April, 1966 [10 May, 1965], No. 19614/65. Heading C1M. In an apparatus for the production of flat glass especially by the conventional " float " technique the formed glass ribbon is taken off the molten metal bath by a take-up roller 30 mounted in a pit 29 between the " float " tank and the annealing lehr and there is provided a seal between the said tank and lehr comprising a curtain formed from a sheet 35 of heat resistant cloth (e.g. silica or glass-fibre) and a backing sheet 36 of asbestos cloth so mounted as to weight the heat resistant cloth towards the top surface of the glass ribbon. The seal acts to prevent ingress of external atmosphere into a headspace of protective atmosphere provided in the " float " tank. The sheet 35 is of such length as to either just drape on to the glass ribbon surface or to terminate 2 or 3 mm. above it, whereas the asbestos cloth sheet 36 is shorter above the path of travel of the glass ribbon but drapes down the sides of the ribbon on to the roll 30. The sheets are held together between metal plates 42, 43 affixed at their upper ends to two semi-circular rods (45), (46) which slidably fit into a slotted supporting tube 54. This tube 54 is itself attached to the foot of an I-beam 52 fixed in the roof structure above the apparatus. A single such curtain may be used or a plurality in series in two or more compartments between the " float " tank and the lehr. An alternative embodiment, Fig. 5 (not shown), illustrates two such curtains attached to the foot of a single I-beam 52. Further sealing is provided by a carbon brush 34 in contact with but situated below roll 30.

Abstract: 857,824. Moulding-machines. BADISCHE MASCHINENFABRIK A.G. June 21, 1957 [June 22, 1956], No. 19632/57. Class 83 (1). [Also in Group XXX] In automatic moulding installations, the finish-pressed moulding bores are transferred from a roller conveyer C, Fig. 1, to an endless chain platform-type conveyer A which is running continuously and transports them to the pouring station where, after the operation is completed, they are transferred to another roller conveyer D which carries them to the moulding machine. The rollers 6, 61, 6<11>, Fig. 2, of conveyer C are driven by a motor 7 and diminish in size as they approach the junction with the conveyer A. The conveyer C is inclined at a small angle to the conveyer A, and at the junction a spring-controlled stop 9 holds back the first pair of boxes O<11>, U<11> until the box U<11> is engaged by a projection 2 on a platform 1, whereupon it yields to allow the box to pass on to the platform. A limit switch E<1> with double contacts x, y is actuated by the movement of the stop 9. When a box touches the stop, the contacts x, y are opened and the motor 7 is stopped. When the box is engaged by the projection 2 and moved forwards, it presses against the stop and moves it upwards to close the contacts x, x and re-start the motor. A time delay 23 prevents the boxes O<1>, U<1> from approaching the boxes O<11>, U<11> too closely. A limit switch E2, which is closed in its neutral position, is opened by a cam 3 on each platform to break the circuit of the motor 5 when no box is in contact with the stop 9.

Title: Preparation of cyanoalkane carboxylic acids
IPC: C07C/
Filed: 1972-04-27
Abstract: 1335019 Cyanoalkan carboxylic acids STAMICARBON NV 27 April 1972 [1 May 1971] 19650/72 Heading C2C Cyanoalkane carboxylic acids are prepared by reacting (e.g. at -5‹ to +35‹ C.) in an aqueous reaction medium at a pH of 3 to 6 and in the presence of a water soluble cuprous cyanide complex as catalyst, a 1-hydroxycycloalkyl peroxide in the presence of the corresponding cycloalkanone with HCN. The mixture of 1- hydroxycycloalkyl peroxide and the corresponding cycloalkanone may be obtained by reacting H 2 O 2  with a stoichiometric excess of cycloalkanone, and preferably comprises initially more than 0À1 mole of the ketone (e.g. 4 to 15 moles) per mole of 1-hydroxycycloalkyl peroxide. The reaction may also be carried out in the presence of an inert solvent using 0À5 to 5À0 moles of cycloalkanone per mole of 1-hydroxycycloalkyl peroxide. The amount of HCN used is generally 5-80% larger than the stoichiometric amount required and, after completion of the reaction, the aqueous catalyst solution may be recovered and re-used. The HCN although preferably added as such to the reaction medium may also be formed in situ. In the examples, #-cyanocaproic acid, #- cyanovaleric acid and a mixture of #-cyanooenanthic and α-methyl-#-cyanocaproic acids are prepared starting from H 2 O 2  and cyclohexanone, cyclopentanone and α-methylcyclohexanone respectively. Comparative experiments describe the reaction of the 1-hydroxycycloalkyl peroxide derived from cyclohexanone and H 2 O 2  with NaCN and of 1-hydroxy-1<SP>1</SP>- hydroperoxydicyclohexylperoxide with HCN. #-Cyanocaproic acid is the product in each case.

Title: Foldable aircraft wing with mechanism for operating and locking the outboard sectionthereof
IPC: B64C3/56
Filed: 1955-07-14
Abstract: 773,739. Folding aircraft wings. HANDEL, A. J. July 14, 1955, No. 20386/55. Class 4. A foldable aircraft wing includes inboard and outboard spar parts pivoted together and secured to inboard and outboard wings portions A and B, mechanism for locking and unlocking the spar parts, and common means for unlocking said mechanism and then raising the outboard wing portion into the folded position in a continuous operation, and for lowering the outboard wing portion to extended flight position and then locking said mechanism in a continuous operation. In Fig. 2, spars C and D extend within the wing, which is split along a line 24. As in Fig. 5, spar C comprises inboard portions 12 and 13, and outboard portions 14 and 15, portions 12 and 14 being pivoted together at 25. In like manner, the spar D consists of two inboard portions 16 (not shown) and 17, Fig. 2, and two outboard portions 18 (not shown) and 19, Fig. 2, portions 16 and 18 being hinged together. Spar portions 13 and 17 end in inwardly cranked sections 13a and 17a which overlap portions 15 and 19 and the spars have bores 27, 28 and 30, 31 which register when the outboard wing portion B is in the flight position. Detents 29 and 32, (Figs. 2 and 5,)are adapted to enter these registering bores to lock the wing for flight. A easing 33 secured to the inboard wing portion reciprocally mounts a rod 35 on which are pins 41 pivoted to toggle links 36, 43 having pins 37, 44 at their other ends constrained to slide chordwise and pivoted to the detents 29 and rods 45 respectively, these latter being pivoted to the detents 32, so that when rod 35 is moved to the left in Fig. 2, the detents are withdrawn, and when to the right, the detents are inserted. A hydraulic actuator F is pivotally connected between rod 35 and a fixture 51, Fig. 5, and is controlled by a valve 61. If the valve lever 62 is turned to the position shown in broken lines, the actuator contracts, first lowering the wing portion B and then pulling rod 35 to the right, locking the wing. With valve lever 62 in the position shown, the actuator expands, first pushing rod 35 to the left and unlocking the wing, then raising the wing portion B. In an alternative embodiment, Figs. 8 and 9 (not shown), rod 35 rotates bell-crank levers which actuate the detents, the levers being spaced spanwise as far as possible, thus spacing apart the two bores 27 and likewise bores 28, 30 and 31, eliminating high local stresses in the spars.

Abstract: 991, 701. Automatic voltage control. MARCONI CO. Ltd. May 29, 1962 [June 7, 1961], No. 20541/61. Heading G3R. [Also in Divisions H2 and H3] A D.C. to D.C. converter comprises a transformer whose primary winding 2 is connected in series with a semi-conductor controlled rectifier 3 between input terminals 1, 4 and whose secondary winding is connected through a rectifying and smoothing circuit to output terminals 17,19. On firing the S.C.R. 3 current flows through the winding 2 and the S.C.R,and a capacitor 5 previously charged with point a positive to point b, discharges through the resonant circuit 3, 8, 7, 6, until the terminal b almost attains the positive potential of the terminal 1. Subsequent discharge is prevented by rectifiers 8 and 3. In consequence the potential at point c rises rapidly toward that of b. The potential at d also rises to trigger an S.C.R 10 into conducting the potential at d being clamped by a Zener diode 12. The capacitor 5 discharges through the circuit 6,10, 9, 5 which has a short time period, and the voltage drop across diode 9 shuts off the rectifier 3. Current continues in the circuit 1, 2, 5, 6,10, 4 and the potential at a rises to the potential at 1 when the rectifiers 15 and 18 cut off. The current continues in the series resonant circuit 1, 2, 5, 6,10, 4, and the point a commences an approximately sinusoidal half-wave overswing above the potential 1. This half-cycle is not allowed to be completed but is terminated by the triggering of the device 3. The waveform at a comprises a constant length negative-going portion and a positive going portion of variable length. A sample of the rectified output is fed to a comparator 23 which includes a reference potential source and provides an amplified error signal. This is fed to a unit 24 comprising a modulator, amplifier and demodulator which provides a control signal for a variable frequency oscillator 25 whose output is applied to the rectifier 3. A voltage sensitive device, e.g., a relay, 27 across the input terminals is connected to the oscillator 25 and prevents this from operating when the input voltage falls below a predetermined value. The comparator 23 (Fig. 3) comprises a potential divider 28, 29 whose junction is connected through a Zener diode 30 to the base of an amplifying transistor 32. The output of this is applied to a further transistor operating as an emitter follower, whose collector supply is obtained from a potential divider 36, 37, 38 and whose output, obtained across resistor 35 is fed to the unit 24. On switching on output to the unit 24 is obtained only as the condenser 38 slowly charges up.
