Title: Diamond synthesis
IPC: B01J3/06
Filed: 1956-08-24
Abstract: A mixture of carbon and a catalyst is subjected to a pressure and temperature sufficient to permit the conversion of carbon to diamond, heat being applied to the mixture until there is an inflection in the electrical resistance curve of the mixture.  It has been found that in carrying out the method of Specification 830,743 the graph of electrical resistance of the mixture against time shows an inflection at the time that the reaction carbon --> diamond takes place, and so this curve may be used instead of direct measurements of temperature to indicate when the reaction is complete.  Specification 830,210 also is referred to.

Title: A process and apparatus for separating dust from the waste gases of furnaces or kilns
IPC: F27B7/20
Filed: 1930-09-01
Abstract: 360,547. Portland cements. ANDREAS, A., 3, Engelstrasse, Munster, Westphalia, Germany. Sept. 1, 1930, No. 26111. Convention date, Sept. 2, 1929. [Class 22.] In the manufacture of cement &c. the wet or dry raw material, e.g. slurry is preliminarily treated before being fed to the kiln or sintering furnace by passage over a gas-permeable device through which the waste kiln or furnace gases pass thus abstracting the dust from the gases and utilizing the heat of the gases to calcine partially or wholly the raw material. The material is spread on or at the gas-permeable device in such a manner that its particles change their relative positions during their forward movement to the kiln. The fine grains or powder in the raw material may be screened off before the material is supplied to the gas-permeable device or the raw material may be first subjected to a balling, granulating or moulding operation or both screened and granulated. The Figure shows one form of apparatus in which the raw material from a hopper 4 flows to a rotary kiln 1 by gravity over a stationary screen 3 through which the waste gases pass to an outlet 5. The screen 3 may be adjustable as to inclination. Other forms of apparatus are shown and described. The Specification as open to inspection under Sect. 91 (3) (a) comprises an apparatus having a travelling grate delivering the raw material into the kiln through a rotatable shoot. This apparatus is not described in the Specification as accepted.

Title: Improvements in or relating to Breech Loading Guns.
Inventor: ASBURY DORSEY FROST
IPC: F41A3/26
Filed: 1919-10-24
Abstract: 134,530. Asbury, D. F. Oct. 30, 1918, [Convention date]. Ordnance breech mechanism; machine guns.- Consists of non-resilient means for performing the opening, closing, and locking movements of a longitudinally-sliding, interrupted collar, breechbolt, by reversing the recoil energy of the bolt, by a cam device. Fig. 1 is a vertical and Fig. 5 an horizontal longitudinal section of the mechanism with the breech closed. Fig. 2 is a cross-section on the line 2-2, Fig. 1, and Fig. 7 is an underneath plan of the gun. The breech-bolt A comprises a sliding and non-rotating head 14, a rotatable sleeve 16 carrying locking lugs 17, and a rotatable block 28, and moves axially in the barrel extension 11 to open and close the breech. The sleeve 16 has a lateral arm 19 on which two rollers 20, 21 are provided. When the barrel recoils, the roller 20 moves along a cam 24 on the non-recoiling cradle 10, and imparts the unlocking rotation to the sleeve. The roller 21 is thereby caused to traverse a cam-groove 26 in the barrel extension 11 whereby the rotation of the sleeve is coilverted into a longitudinal movement of the entire breech-bolt, the roller 21 being guided into a straight portion 25 of the groove 26. During the unlocking period, the block 28 is held against rotation by a spline 37 in the barrel extension, but afterwards moves clear of the spline, and a camgroove B in the block 28 encounters a roller 31 in the barrel extension. The groove B comprises two longitudinal portions 29, 30, connected by inclined portions 32, 33 with a circumferential portion 34. The action of the roller 31 on entering the portion 29 of the cam groove is therefore to impart rotation to the block through the incline 32 and to arrest the rearward movement of the breech-bolt. The block 28, however, rotates until the roller engages the incline 33 when a forward movement is imparted to the breech-bolt, and the rotation of the block 28 is stopped. The roller 31 leaves the groove by the exit 30. The forward motion carries the breech-bolt into the locking position, and the locking rotation is imparted to the sleeve 16 by the cam-groove 26. During the next recoil, the roller 31 enters the groove 30 and the block 28 is rotated in the opposite direction, but the action is unchanged. Two key-ways 35, 36 are formed in the block to enable it to engage with the spline 37 both during recoil and counter recoil. An extractor 42 moves in a groove 44 and prevents rotation of the breech-bolt head. When it engages the incline 43, the extractor is pressed inwards and ejects the cartridge case. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the invention is applicable to non-automatic guns and to guns with screw and wedge breech-blocks. This statement does not appear in the Specification as accepted.
