Title: Improvements in and relating to the Projection of Grenades and the like.
IPC: F41C27/06
Filed: 1916-10-07
Abstract: 109,509. Guns & Munitions, Ltd., and Doubleday, V. C. Oct. 7, 1916 Ordnance pneumatic; projectile fuses, devices on gun for firing; design.-The Specification describes devices provided on or in the barrel of a gun or the like, whereby a casing surrounding u grenade is detached from the projectile on discharge, so that the fuse-controlling lever is released. According to the invention, the grenade is, before insertion in the gun, placed in the casing, which is open at one end and fits the gun-barrel. On discharging the casing containing the grenade from the gun, the casing is stopped at the muzzle whilst the projectile passes on, and the lever, which has been retained at " safe " by the casing, is then free. To stop the casing and detach it from the grenade, an extension a, having a cntaway portion c provided with a flange d, may be detachably secured to the muzzle. The part a may be perforated at e. Instead of being a separate attachment, the part a may be integral with the gun-muzzle b. In a modification, the device for stopping the casing consists of converging longitudinal strips projecting from the muzzle. Another means for separating the casing from the grenade comprises steel balls or the like, resiliently mounted in recesses in the gun-barrel, and adapted to retard the casing as it passes out. Specification 9794/15 is referred to. The Provisional Specification refers to the use of the invention with a pneumatic gun.

Abstract: 1,137,752. Endless conveyers. OWENSILLINOIS Inc. 31 March, 1966, No. 14314/66. Heading B8A. Bottles on a conveyer 11 back up against a leading bottle held by a stationary star-wheel 23 until a predetermined number of bottles has collected, the last of which operates a switch (43), (Figs. 3 and 5, not shown). This releases a stop 31 engaging a projection 30 on a gear 27 meshing with the star-wheel and the predetermined number of bottles are permitted to flow out on to a delivery conveyer (38). The retraction of the stop 31 operates a switch 54 which results in immediate re-projection of the stop 31. Thus the gear 27 is stopped after one whole revolution. Three conveyers 11 are disposed in parallel, each with an associated star-wheel 24 and each serving the conveyer (38). A switch (58a) on the conveyer (38) ensures that none of the star-wheels permits a further delivery until all the previous bottles have got away on the conveyer (38). An arrangement of switches (53), (54) and (55), ensures that the gates respective to the three conveyers are operable with a predetermined precedence.

Abstract: <PICT:0487281/III/1> <PICT:0487281/III/2> In a device for detecting the concentration of combustible gases, e.g. methane in mine atmospheres, a sample of the gas is primed by the addition thereto of a vaporized supplementary fuel, whose vapour concentration is automatically regulated preferably to a constant value, and is then subjected to ignition, an eventual explosion being utilized to operate an indicating device.  In the illustrated apparatus, the gas is forced by a diaphragm pump 16 into a space 4 in which a candle 2 of naphthalene mixed with b -naphthol is pressed down by a spring 3. The candle is heated by means (not shown) which may be automatically regulated by a device 15 responsive to variations of atmospheric pressure, so as to maintain a constant vapour pressure of naphthalene.  The primed gas passes to an explosion chamber 5 fitted with a sparking plug 7 which is periodically actuated through a synchronous motor.  The chamber has a diaphragm pressure gauge 8 which on the occurrence of explosion makes a contact 9 closing the circuit of the indicating device.

In an impeller for a centrifugal compressor or blower having radial blades, inside walls and outside walls forming a flow path between each pair of adjacent radial blades, the flow path in the meridian plane of the blades has a curvature in which the slope at any point along the flow path coincides with the slope of the resultant of the centrifugal forces at the point due to the rotation of the impeller and the curvature of the path in the meridian plane. This ensures a uniform distribution of velocity throughout the flow path and prevents separation of the fluid from the inside and outside walls.
