Title: Improvements in or relating to brake and clutch mechanism
IPC: F16D67/06
Filed: 1945-06-26
Abstract: 594,739. Friction clutches. LEAR, Inc. June 26, 1945, No. 16256. Convention date, Sept. 2, 1944. [Class 80(ii)] [Also in Groups XXXIII and XXXIV] A brake and clutch unit comprises a driven member which when disengaged from a driving member engages a brake member under the action of a speed responsive device whereby the brake is applied only as long as the speed is above a chosen value. The invention is useful in driving means such as described in Specification 587,626 in which a number of individual power units 10, 15 are provided for operating for example, wing flaps 13, 14, landing gear or other components of aircraft. To provide for operation of any components in the event of failure of the power in its associated unit, groups of units may be mechanically interconnected as by flexible shafting 40 by which manual operation by a handle 26 may also be effected. The position of the flaps 13, 14 is indicated by a movable pointer 24 cooperating with indicia 23. Each power unit 10, 15 is mounted on a fixed part 11, 12 and comprises an electric motor 20 to the shaft 33 of which is keyed the driving member 31 of an electromagnetic clutch and brake of the type described in Specification 549,552. The driven member 37 of the clutch is secured to a shaft 46 which is geared to screw-and-nut mechanism 35 by which the wing flaps 13, 14 are operated. Members 31, 37 and members 48, 51 in which the brake and clutch control coil 50 is housed are of magnetic material an annular non-magnetic insert 36 being provided in member 31. With the motor and the coil 50 energised, the member 37 is held engaged with member 31 to drive the shaft 46. When the coil is de-energised centrifugal balls 56 in a conical recess 53 in member 31 are able to move the member 37 upwards to engage a braking surface 52 until the speed of the motor armature with the member 31 falls to value such as permits the return of the balls and of the member 31 to the position shown. The shaft 46 is thus stopped by the brake which however is subsequently released automatically so that the shaft may be driven without hindrance by the brake by the shafting 40 if the associated motor should fail. In a modification the balls 56 are normally disposed in a groove at the inner part of the conical recess which prevents them from moving outwards as long as the coil 50 is energised. Hardened wear plates are also provided for the recess.

Title: Improvements in or connected with pressure cabins for aircraft
IPC: B64D13/04
Filed: 1942-11-18
Abstract: 581,142. Aircraft pressure cabins. VICKERS - ARMSTRONGS, Ltd., and WALLIS, B. N. Nov. 18, 1942, No. 16338. [Class 4] An aircraft pressure cabin comprises two or more rigid non-circular frames or bulkheads to which a mesh or network of flexible tension members is. connected enclosing an airtight flexible inner skin, the tension members being so arranged that the lateral loading thereon due to the internal pressure on said skin is so varied that the network assumes the same shape in cross-section as that defined by the rigid frames or bulkheads. An inverted U-shaped cabin is shown in which successive transverse frames 10 are connected by longitudinal members 13, 14 to which and to the frames 10 are secured the ends of inclined wires A forming a mesh which is closer near the lower part of the cabin, where the curvature of the wall is flatter, than it is at the top of the cabin. The wires support an inner flexible skin 15. The floor 11 is rigid and made impervious. The lateral loading on the wires due to the pressure on the skin varies.inversely as the radius of curvature of the cross-section of the cabin. A modification is described in which each transverse frame is formed of three circular arcs, an upper arc joined to two side arcs of flatter curvature. In this case the network is divided into three zones, of uniform mesh in each zone, connected to longitudinal wires 17, Fig. 4, arranged at the position of the change of curvature, the meshes in the upper zone being wider than those in the two side zones. A second pressure space may be formed beneath the floor 11 and may be of the same shape as the upper space but inverted. The main framework of the fuselage may be of geodetic structure as shown in Fig. 1 and the outer covering may be as described in Specification 574,090. The space between the outer covering and the network may be filled with wool noil. Specification. 233,020, [Class 4], also is referred to.

Title: Multi-path optical systems
IPC: G03B33/12
Filed: 1953-06-16
Abstract: 735,745. Optical systems. RADIO CORPORATION OF AMERICA. June 16, 1953 [June 28, 1952], No. 16594/53. Class 97 (1). In a light-dividing system comprising at least two partial reflectors arranged in series to produce at least two subsidiary light beams and a direct beam of substantially equal intensity each reflector comprising a transparent body supporting a layer reflecting and transmitting different colours, a transparent compensating member of substantially the same thickness as that of each reflector and of the same refractive index as the supporting bodies thereof is inserted in one of the beams to equalize astigmatism for paraxial and oblique rays. As shown in Fig. 1, for the purpose of effecting colour correction of three transparencies 16, 17, 18 they are illuminated by light from the spot of a cathode ray tube 11 by way of a lens 12 and light dividing system 13, the resulting light falling on photo-cells 23, 24, 25. The system 13 comprises a member 14 consisting of a semi-reflecting layer supported between two glass plates and reflecting a beam to the transparency 17, the beam passing through an inclined plate 26 of the same material and thickness as the combination of plates in the member 14. The beam transmitted by the member 14 is divided by a similar reflecting member 15 to fall on transparences 16 and 18. By this arrangement each beam will have passed through a thickness of glass equal to twice the thickness of each of the members 14, 15 and 26 and will have been incident on these members at the same angles so that the beams will have the same astigmatism. In the modification shown in Fig. 4 the beam from the lens 38 passes an inclined plate 39, is partly reflected by a front surface reflector 44, the reflected beam being divided by a further front surface reflector 45 whereby three beams are formed, the.astigmatism in the beams being again equalized by an inclined plate 43.

Abstract: 864,523. Automatic gramophones. BIRMINGHAM SOUND REPRODUCERS Ltd. July 9, 1957 [May 29, 1956], No. 16607/56. Class 40 (2). Means to initiate drive of a gap wheel 7, when the pick-up of an automatic recordchanger enters the run-out groove, comprises two frictionally-coupled elements mounted thereon (e.g. plates 11, 12 pivoted at 13); one of these, 11, is moved in one direction by the tone-arm 3 during reproduction and subsequent run-out, and returned by a part rotating with the turntable pinion 9 (e.g. by its actual teeth, or by a separate cam) when the gap wheel 7 is driven thereby; the other, 12, has a part 19 engaged by eccentric means (such as an extended tooth 22) rotatable with the pinion 9, to cancel its slow advance during reproduction, Fig. 12, but to pick up a drive during run-out, Fig. 13, sufficient to bring the gap wheel 7 and pinion 9 into mesh. A lug 20 on the plate 12 passes through a notch 18 in the plate 11 to a slot 21 in the wheel 7, whereby the movements of the plates 11, 12 are positively limited, the lostmotion between parts 20, 18 allowing for the cancellation of the slow advance of the plate 12. As shown, the inward motion of the tone-arm 3 is conveyed to the plate 11 by an arm 24 engaging a bar 26 longitudinally slidable beneath the deck 1, the inner end of the bar having a V-shaped lug 28, the tip of which, in the idle position of the gap wheel 7, contacts a pin 14 projecting from the plate 11 through a slot in the wheel 7. After the tone-arm 3 has been swung outwards during the automatic cycle, a pin projecting beneath the wheel 7 engages a side of the V-shaped lug 28 to restore the bar 26, and the teeth of the pinion 9 engaging an inclined edge 17 of the plate 11 progressively restore the latter, which by engagement of the notch 18 with the lug 20, retracts the part 19 from the path of the tooth 22.

[Class 54] In a dry gas meter the casing 12 for the measuring chambers is of cylindrical form and is made of asbestos material, the ends being closed by plates 43 of the same material spigotally fitting therein and secured by screws. Internally the casing 12 is formed with two grooved peripheral flanges 39 to receive the edges of the diaphragms 37, which are retained in position by outwardly springing circlips 40, and with a central peripheral flange 41 to which the dividing partition 42 is secured. Seated on the upper part of the casing 12 is a passage member 13 closed on its upper side by an apertured valve plate 14 carrying the grills 15 with which the valves 16 co-operate. These valves are operated through links 18 from a crank-shaft 19 which actuates the counting mechanism 20 and is itself driven by tangent arm 21 connected to the flagshafts 22, 23. The latter are cranked as shown and the provision of a footstep bearing inside the casing is avoided by supporting the shaft by a split pin 27 engaging a part-spherical bearing member 28 which rests on a bracket 29 bolted to a casing 31. In the form shown in Figs. 1 and 2, the upper mechanism is enclosed in a sheet metal or asbestos cover 56 having side walls 57, whose lower straight edges 58 rest against the casing 12, and end walls 60 formed with arcuate lower edges 59 to fit against the end plates 43. In the modification shown in Fig. 7, this cover is of inverted channel form, its open ends being closed by upward extensions 60a of the end plates 43.

Title: New primary alcohols
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C45/50
Filed: 1955-06-15
Abstract: The invention comprises the new primary alcohols 3-ethylheptanol-1 and 3-ethylhexanol-1 and mixtures comprising 3-ethylhexanol-1 and 3-methylheptanol-1.  The compounds or compositions may be prepared by the dimerization of butene-1 or of a propylene and butene-1 mixture followed by carbonylation and hydrogenation of the dimerization product.  The dimerization of butene-1 gives 2-ethyl-hexene-1 which on carbonylation and hydrogenation gives 3-ethyl-heptanol-1.  A mixture of propylene and butylene on dimerization gives 2-methylpentene-1, 2-ethyl-hexene-1 and a mixture of 2-methyl-hexene-1 and 2-ethyl-pentene-1 and on carbonylation and hydrogenation these give 3-methyl-hexanol-1, 3-ethyl-heptanol-1 and a mixture comprising 3-methyl-heptanol-1 and 3-ethyl-hexanol-1 respectively. The dimerization takes place in the presence of one or more aluminium alkyl compounds, such as aluminium tri-ethyl, at elevated temperature in a sealed vessel and may be carried out batchwise or continuously.  The dimer product is carbonylated in the presence of a cobalt catalyst by a mixture of carbon monoxide and hydrogen at superatmospheric pressure and temperature.  The product is freed from carbon monoxide and is hydrogenated at elevated temperature and pressure in the presence of cobalt retained from the carbonylation or in the presence of a hydrogenation catalyst such as copper-zinc oxide.  The cobalt catalyst may be added as an organic compound soluble in the reactants or as a catalyst on a support such as kieselguhr.  In the examples: (a) a mixture of propylene and butene-1 is dimerized in the presence of a mixture of aluminium tripropyl, aluminium tributyl and decahydronaphthalene, to give a mixture of 2-methyl-pentene-1, 2-methylhexene-1, 2-ethyl-pentene-1 and 2-ethyl-hexene-1; the co-dimer heptenes are carbonylated in the presence of a cobalt-on-kieselguhr catalyst and the product is hydrogenated to give a mixture of 3-ethyl hexanol-1 and 3-methyl heptanol-1; (b) 2-ethyl-hexene-1 obtained by the dimerization of butene-1 as in (a) is carbonylated in the presence of a cobalt naphthenate catalyst and the product is hydrogenated using a copper-zinc oxide catalyst to give 3-ethyl-heptanol-1.
