Title: Improvements in or relating to ordnance breech mechanism
IPC: F41A5/32
Filed: 1925-09-16
Abstract: 261,872. Dawson, Sir A. T., and Buckham, Sir G. T. Sept. 16, 1925. Ordnance breech mechanism.-Semi-automatic guns of the vertically sliding breech-block type, adapted also to be operated by hand, are provided with two breech-closing springs one of which is always in action while the other is inoperative when the mechanism is operated by hand. The first spring approximately balances the weight of the breech-block. The breech mechanism shown comprises a breech-ring A, vertically-sliding block B, breech-actuating crank-shaft D and hand-lever C. The balancing spring E, Fig. 3, is mounted in a recess at the left side of the breech-ring A and is acted upon by a rack member E<2> engaging a part pinion D' on the crank shaft so that this spring E is compressed whenever the breech is opened, whether automatically or by hand. The main closing spring F is mounted in the hand-lever C and acts upon a rack F<2> engaging a part pinion D<5> on the crank shaft. During semi-automatic actuation, the hand-lever C is locked to the breech-ring by a plunger C', Fig. 5, and the spring F is compressed when the breech is opened. During hand actuation, the handlever C is locked to the crank shaft D by a catch C<4>, Fig. 5, which is turned by a hand grip C<5> to engage a notch D<6> in the part pinion D<5>. The spring then merely moves with the hand-lever without being compressed. The semi-automatic mechanism comprises a crank D<2> having a lateral projection D<3> co-operating with a cam D<4>, Fig. 3, as described in Specification 261,500.

Title: Process of manufacture of products imitating pearls and mother-of-pearl without the use of pearl essence
IPC: B44F9/08
Filed: 1924-10-03
Abstract: 222,881. Paisseau, J., and Warcollier, R. Oct. 4, 1923, [Convention date]. Gems.-In the manufacture of imitation pearls, mother-of-pearl &c., extremely fine crystals are incorporated in an agglutinating substance such as gelatine, celluloid, cellulose acetate, viscose, condensed resins, &c. The crystals may be obtained by precipitating fatty acids from soaps by water, or uric acid from urate of soda by an acid. Crystals, such as those of heavy metal salts, having an index of refraction as different as possible from that of the agglutinating substance are preferred. Specification 207,144 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of gas bubbles to a mass of agglutinant, either by chemical means, or by the introduction of crystals which are subsequently dissolved, leaving interstices of the shape of the crystals. This subject-matter does not appear in the Specification as accepted.

Abstract: 277,347. M³ller Akt.-Ges., C. H. F., Assignees of Thaller, R.). Sept. 7, 1926, [Convention date]. Vacuum tubes. - In Lenard cathode-ray tubes in which the cathode rays from a highly emissive cathode pass out of the tube through their aluminium or other foils, the foils are cooled during normal operation of the tube by blowing a current of gas or liquid on to them. The foils are thus protected from damage due to the heat produced by the absorption of some of the electrons, so that the cathode emission and radiant energy may be increased. Discharge voltages of 250,000 volts with incandescent cathodes, also tubes constantly connected to a vacuum pump, are referred to. In a tube with a spiral incandescent cathode 2 and annular anode 3, the foil 4 is supported by a grid 5 and cooled by gas jets from nozzles 8 in an annular pipe 7.

In the preparation of processed pasteurised cheese, an intimate mixture of cheese, water, a fat-casein emulsifying agent, and a protolytic enzyme, having a specific activity between 10000 and 2000000 and which is effective at pH 4.0-7.0, is formed at a temperature at which the enzyme is active, heated to a temperature sufficient to pasteurise and emulsify the mixture, and then cooled. The emulsifying agent may be a phospate, citrate or tartrate. The enzyme may be plant derived, for example papain, ficin, or bromelain; animal derived, for example trypsin, pancreatin, or chymotrypsin; or fungus or bacteria derived. It is particularly advantageous to employ a preformed mixture of enzyme and emulsifying agent.

Abstract: 1353777 Stereoscopic photography and viewers AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 19 April 1971 [13 March 1970] 23905/71 Headings G2A and G2J A stereoscopic camera comprises a chamber having an elongated window, a lenticular photographic surface either inside or facing into the chamber, and an optical system having two parts, one part including an objective lens mounted adjacent the window for reciprocating travel longitudinally thereof, and the other part within the chamber which forms stereoscopically related images of an object at the said surface. As shown, the chamber 33 has an elongated window 34, across which extends an opaque blind 41. This winds across between cylinders 44, 45, and has an opening for admitting light. The first part of the optical system is housed in a box 24 which can slide along rails 31, 32, and consists of a rightangle roof prism 25, a small-aperture diaphragm 26, an objective 27, and a right-angled prism 28. Light from this unit is reflected into the chamber 33, passing through a semi-transparent mirror 37 to a concave mirror 36, which reflects it back to mirror 37 and then to the plate 39 having a surface of cylindrical lenticular elements backed by a photo-sensitive layer 40. The movements of unit 24 and blind 41 are synchronized. Thus as unit 24 is moved, a series of stereoscopically related images is produced. In an alternative arrangement, Figs.6 and 7 (not shown), the photosensitive layer and the objective move in synchronization, the former twice as fast as the latter. The camera of Fig.4 may be adapted to form a viewer for observing the images. The unit 24 is removed, and the chamber 33 inverted and mounted on a further chamber 66 containing a point light source 67. This is converted into linear light sources by a lenticular plate 69. These pass through the developed images on plate 39, and the light rays pass back along the same path as those originally forming the photograph, and can be viewed through the opening 34 in which the unit 24 was mounted.

When the apparatus is started, the carriage 3 is reciprocated by a motor, by selective engagement with the upper and lower rim of a chain 2, and the workpiece is fed through a sewing-machine 4 to an aperture 16 in the table, through which the front end of the workpiece 47, Fig. 4a, falls. When the rear end of the workpiece clears a photoelectric detector 38, a stacking device 17 is operated. A two-way pneumatic cylinder 18 causes members 44, Figs. 4a and 4b, to move to the left, thus moving an element 24 carried on pivoted elements 23 clear of an inverted U-shaped platform 27 against spring 26, thereby releasing a rod 46, which is moved by a smaller one-way pneumatic cylinder 19 to clamp the workpiece against the side of the platform, while the rod 23 drapes the rear end of the workpiece, when released by the clamp, over the platform. When the element 24 moves to the right, it clamps the rear of the workpiece against the platform. After a desired number of workpieces is counted as being draped over the platform, the stacking device is not operated, and a following workpiece falls into a tray 29.
