Title: Flush fastener
IPC: B64C1/14
Filed: 1944-11-30
Abstract: 587,503. Fasteners. WAITE, G. W. Nov. 30, 1944, No. 23888. [Class 44] A fastener comprises a cylindrical member adapted to be rotated and moved axially within a housing, a lever pivoted to the member projecting through a slot in the housing parallel to the axis of the cylinder. The member and the operating lever are normally flush with the outer surface of the housing, but the lever becomes exposed when the member is pressed into the housing. A reduced portion B<1> of a cylindrical member B slidably received within a housing A, Fig. I, protrudes through a hole in the base of the latter and carries a plunger B<2> of square section adapted to engage a corresponding square hole in a latch follower when the member B is pressed inwardly by thumb pressure against the action of a spring D. A pin C acts as a retainer. A lever E received within a slot A<1> in the housing A and a corresponding slot B<3> in the member B and pivotally connected to the latter at F pivots about a corner M against the action of a spring G when the member B is depressed, and protrudes sufficiently to be grasped by the fingers. The member B can then be turned through 90‹ by means of the lever E, the heel H of the latter sliding in a circumferential slot K, Fig. II, and a groove J accommodating the corner of the flange A<2>. In an adaptation to an aircraft cowling fastener or the like, a transverse pin carried by the portion B<2> locks into an elliptical hole in a flange on an airframe member.

Title: Improvements in axle arrangements for vehicles
IPC: B60G15/06
Filed: 1932-08-26
Abstract: 394,834. Vehicle suspensions ; under-frames; shock-absorbers. BROULHIET, G., 201, Rue de Grenelle, Paris. Aug. 26, 1932, No. 23902. Convention date, Aug. 28, 1931. [Classes 108 (ii) and 108 (iii).] The ends 1b of a cross member 1 of a vehicle frame are extended upwards forming supports on which slides and pivots, through the intermediary of a plain bearing 8 and a.ball cage 11, a socket 5 carrying a stub axle 6. A socket 10 is mounted on each of the sockets 5 and a ball race 12 is connected to one end of a transverse suspension spring 4 by links 13. Each support 1b forms a cylinder in which a piston 17 is reciprocated by a piston rod 16 connected to the socket 10. Upward movement of the sockets 5, 10 opens a non-return valve 21 and closes a non-return valve 27, oil being able to flow from the space 23a through apertures 24, 25 which are provided with grooves 24a, 25a respectively. The grooves allow flow of oil past a partition 18a in the cylinder, the space 19 acting as a reservoir. On downward movement of the sockets the valve 27 opens and the valve 21 closes. The bearing 8 includes a ring 9 of oil resisting rubber and the member 1 is bent so that the spring lies in the same plane as the supports. The shock-absorber may be constructed as set out in Specification 378,699.

Title: Improvements in and relating to speed regulating and current limit motor control systems
IPC: H02P7/34
Filed: 1954-08-17
Abstract: 785,036. Automatic speed control systems. IGRANIC ELECTRIC CO., Ltd. Aug. 17, 1954 [Aug. 26, 1953], No. 23904/54. Class 38 (4). In speed plus current limit control systems for D.C. motors the speed error signal is shunted from the regulator on attaining a certain value by the non-linear conducting characteristic of a rectifier. Two embodiments are described in which the motor is supplied- (i) from grid-controlled rectifiers; (ii) from a Ward-Leonard generator. Rectifier supply.-Motor 14 driving a tachometer-generator 21 is supplied through rectifiers 12, 13. The error between the output of the tachometer 21 and a reference tachometer 22 is applied to a magnetic-amplifier 18 controlling the phase-shift in the rectifier grid circuits. The reference source may alternatively be a battery, Fig. 2 (not shown). The motorcurrent-signal derived from a current transformer 11 (in the supply to rectifiers 12, 13), is rectified at 29 and compared with a limit reference signal from rectifier 33 to exert an overriding control on the magnetic amplifier. This is assisted by a portion of the speed error signal tapped off from potentiometer 26 to assist the current limiting signal. Further, when the speed-error signal attains a certain magnitude (due to current limiting action), a port of the signal is shunted from the magnetic amplifier by rectifier 27. Ward-Leonard systems, Fig. 3 (not shown).- The speed and current limiting signals are similarly applied to a magnetic amplifier controlling the excitation of the generator, and the current signals are derived from a saturablereactor controlled by the loop current (instead of a current transformer).

Patent GB-899651-A (GB)
Title: Improvements relating to the refining of gasoline
IPC: C10G45/06
Filed: 1958-07-25
Abstract: The tendency of a gasoline containing unsaturated hydrocarbons to form gum is reduced by hydrogenating the gasoline in the presence of a supported catalyst containing nickel (which, under the operating conditions, is present in major proportion as elemental nickel), the hydrogen consumption being at least 120 standard cubic feet/barrel but below that at which hydrogenation of mono-olefins and/or aromatics exceeds the amount which would give a final product having a research octane number (with 1,5 ml. tetraethyl lead/Imperial gallon) more than one number below the research octane number (with 1,5 ml. tetraethyl lead/ Imperial gallon) of the feedstock.  The catalyst support may be activated or deactivated alumina, a Group II metal carbonate, an oxide of calcium, barium, strontium or magnesium, sepiolite, diatomaceous earth (or firebrick derived therefrom), silicon carbide, quartz, carbon or pumice.  The support may be mixed with an asily decomposable salt of nickel (e.g. the nitrate or acetate) and the mixture pelletted, or alternatively the support may be impregnated with an aqueous solution of the nickel salt and then dried.  In each case, the supported catalyst may be roasted and then activated by heating in a current of hydrogen.  Where the nickel salt employed is the formate, the roasting step may be omitted and activation effected by heating in a current of inert gas.  The hydrogenated gasoline may be rerun to remove a small proportion of heavy ends.  In the examples, gasoline obtained by the steam-cracking of a petroleum fraction is hydrogenated in the presence of a nickel catalyst supported on chalk, alumina or sepiolite.  Specifications 848,232, 899,652 and 899,654 are referred to.

Abstract: 650,198. Tyre building apparatus. UNITED STATES RUBBER CO. Sept. 22, 1948, No. 24760. Convention date, Dec. 29, 1947. [Class 144 (i)] A tyre building apparatus comprises a rotatable tyre building drum 5, an auxiliary drum 8, of smaller diameter, rotatable therewith and carrying a pocket 4 of tyre fabric (wire or textile fabric), and means 17 engaging the external surface of said pocket 4'to produce a lateral component of the centrifugal force acting on the rotating pocket and move it laterally from the auxiliary drum on to the building drum. As shown, the auxiliary drum 8 is rotatably mounted on a shaft 9 which is pivotally supported on a spring-urged retractable carriage 11 to allow the drum 8 to be swung out of axial alignment with drum 5 and facilitate the placing of the tyre pocket 4 on said drum 8. The two drums 5, 8 are bridged by a conical lead 15 bearing on a shoulder 24 of the drum 5 and having spring fingers 16 engaging the inside of the drum 8, said drum 8 being driven frictionally by the drum 5 through the lead 15 or having a separate drive. The pocket-moving means 17 comprises a widerimmed stitcher wheel adjustably mounted on a movable arm 18 and arranged to engage the tyre pocket 4 at the base of the lead 15. The stitcher wheel is arranged edge-on to the pocket 4 and inclined at one angle of 15 to 30 degrees to the vertical so that when the pocket is expanded by the centrifugal force of rotation, it is urged over the lead 15 on to the drum 5. The outer end of the pocket 4 is prevented from flapping on the drum 8 during rotation by a temporary strip 22 of adhesive tape which is removed as the said end approaches the lead 15.
