Inventor: GLOVER ARTHUR WILLIAM
IPC: F42B33/06
Filed: 1916-10-02
Abstract: 109,999. Glover, A. W. Oct. 2, 1916. Projectiles.-Relates to apparatus for gripping ordnance shell bodies and for unscrewing or screwing in their fuse-hole plugs, and consists mainly in the provision of a special gripping-appliance. The apparatus comprises a frame 1 having a base 2 recessed to receive a shell-body 28, which can be clamped in an upright position in the recess by a U-shaped strap 5 pivoted to a bracket 6. The part. 6 constitutes a toggle-lever and is provided with a hand-lever 7. The upper part of the frame has two arms through which passes a vertical spindle 15, carrying at the lower end an interchangeable head 17 fitted with projecting screws 19 and a blade-like projection 35. When a shell from which a wooden plug is to be removed is clamped in position, the spindle 15 is pressed down by means of a lever 9 acting through a forked lever 12, so that the parts 19, 35 are forced into the plug. The spindle is then rotated by means of a hand-wheel 16 operating through suitable gearing, and the spindle is at the same time automatically raised by a spring 20. To insert a metal plug, the plunger-head 17 is removed and replaced by another having suitable means for engaging the plug.

Title: Commutator with one Anchor Location
IPC: H01R39/04
Filed: 1969-03-18
Abstract: 1,189,976. Commutators for dynamo-electric machines. WESTINGHOUSE ELECTRIC CORP. 18 March, 1969 [2 April, 1968], No. 14095/69. Heading H2A.

The depth of the recess is smaller than the height of the projection so that when the assembled bars, held together by rings 30, are shrunk on to the bushing, a heavy shrink fit is obtained around the projection and a lighter fit over the remainder of the bushing whereby in operation the bars can expand axially without buckling or breaking the risers.
Patent GB-849511-A (GB)
Title: Improvements in the manufacture of microporous metallic tubes consisting mainly of nickel
Inventor: NGUYEN-THIEN-CHI
IPC: B01D59/14
Filed: 1958-05-02
Abstract: Microporous tubes (pores of the order of 0.01 micron) are made by crushing a moist powder Ni or nickel oxides to remove agglomerates, coating the grains so formed with a binder volatile at 200 DEG -400 DEG C. (e.g. gum tragacanth, alginates), extending the paste then obtained into tube form, dehydrating (e.g. in acetone) and drying, and finally sintering these tubes.  The grains may be formed by reduction of nickel formate or oxalate in hydrogen at 150-750 DEG C. During crushing, the grains are mixed with binder to form a paste and the paste is extruded several times to form vermicular threads, further binder being added between at least some of the extrusion operations to give a binder content of 2-10%.  The paste is extruded to tube form and the tubes dehydrated, e.g. in a bath of acetone. Dried tubes are placed on smooth cylindrical supports, e.g. of nickel or cupro-nickel, coated with alumina to prevent sticking, the diameter of the supports being preferably slightly less than the internal diameter of the tubes to allow for shrinkage.  The tubes are then placed in a muffle and introduced vertically into a sintering furnace and sintered at 500-900 DEG C. in hydrogen, inert gas or vacuo.

Title: Improvements in or relating to combined ventilating and brake testing installations for internal combustion engines
IPC: G01M15/02
Filed: 1936-05-19
Abstract: 464,539. Dynamometers. DEUTSCHE VERSUCHSANSTALT FUR LUFTFAHRT, E. V. May 19, 1936, No. 14218. Convention date, May 21, 1935. [Class 106 (ii)] Comprises a combined ventilating and brake installation for testing air-cooled motors in which the blower and brake are arranged coaxially. A wind channel a is mounted on a frame b in which a helical and compression blower b and braking device d are arranged symmetrically about the axis of the channel. Behind the blower c is a motor e and cooler f all surfaces being smooth. Externally of the channel a is arranged on the same shaft the motor g to be tested. The air passing the blower drive may be used to cool the electric brake. If necessary the air can be carried through an air-cooler mounted between the motor driving the blower and the brake. Further, the blower may have adjustable blades and may be fitted directly on the axle of the braking device thus dispensing with a separate driving motor. To measure the energy supplied to the blower, suitable coupling elements permitting measurement of torque may be provided at this point. The torque can be found by arranging similar couplings between the brake and machine under test. The blower may also be used to give an additional load to that given by the brake. In this case the shortest constructional length for the installation is produced.
