Title: Improved method of mounting machine guns
IPC: F41A25/10
Filed: 1937-04-22
Abstract: 494,304. Automatic guns. BOULTON PAUL AIRCRAFT, Ltd. (Soc. D'Applications des Machines Motrices) April 22, 1937, No. 11474. [Class 92 (i)] Relates to automatic machine guns of the kind in which the gun-support 2 is adapted to recoil with respect to the gun mounting 4 against the action of combined spring and energy-absorbing damping means which serve to control the recoil and run-out. According to the invention, the stiffness of the spring 6 and the value of the damping force are so related to the mass of the recoiling parts and the force of recoil that, when the gun is firing continuously, the support 2 does not return to its initial position but is kept in steady oscillation at a periodicity equal to the gun's normal rate of tire, each shot being fired during run-out at the same phase of the period, and the amplitude of recoil being thereby reduced. In the form shown, the machine gun is attached by lugs 5 to the support 2 which slides on guides 3. The spring 6 of chosen stiffness is initially adjusted by a screw 8 until the support 2 bears against buffers 9. Frictional damping on the guides 3 is adjusted by screws 10. The amplitude of recoil is represented in Fig. 4 as D for the first shot and d for continuous fire and the first and subsequent shots are fired at the periodic times marked A<1> to A<6>.

Title: Improvements in or relating to hermetically sealed tins and other containers, and a method of sealing the same
IPC: B65D77/20
Filed: 1932-04-21
Abstract: 400,255. Hermetically sealing tins, bottles, &c. RICHARDSON & SONS, Ltd., W. J. and RICHARDSON, D. S., 199, Borough High Street, London. April 21, 1932, No. 11509. [Class 125 (iii).] In a method of hermetically sealing tins, bottles, &c.. of the type wherein a seal in the form of a thin sheet of material, e.g. metal foil or regenerated cellulose, is held in its closing position on or in the mouth of the tin &c. by an annular member which clamps the marginal portion of the seal against an annular co-operating portion of the container, the annular member and the co-operating portion are of such a size-e.g. of equal diameterbefore being assembled that their clamping faces will make a press fit one with the other when assembled, the annular member gripping the marginal portion of the seal between it and the co-operating portion of the tin &c., thereby causing expansion of the outer member, or contraction of the inner member, or both, to accommodate the thickness of the interposed seal. As shown in Fig. 6, the annular member consists of a hollow annulus which is deformed by the pressure of a frictionally-seating lid 30. Ribs 36 may be formed in the tin &c. neck, as shown in Fig. 7, or in the inner wall of the annulus, or in both, or a single, groove 38 may accommodate a rubber ring 40 as shown in Fig. 8. The outer surface of the hollow annulus may be screw-threaded as at 29, Fig. 9, to receive a screw-threaded or bayonet-jointed lid. The lower rims of the annulus may be rolled up, as in Fig. 11.

Abstract: 906,686. Television. DEUTSCHE TAFEL GLAS A.G. DETAG. March 30, 1961 [March- 31, 1960], No. 11650/61. Class 40 (3). The protective pane of glass disposed in front of the screen of a television picture tube 2 has its upper portion 4 of planar configuration and arranged substantially vertically whilst the lower portion 4a is of substantially cylindrical curvature with the radius of curvature corresponding to that which the tube screen has at its intersection with a vertical centre plane disposed normal thereto. This arrangement retains the advantage of known planar safety glass arrangements of preventing undesired reflections of extraneous light whilst providing for a reduction in the overall depth of the structure by allowing control elements, such as 5, to be positioned in the space " gained " by the curving of the lower portion 4a. The protective pane may be formed of hardened safety glass or of laminated safety glass. In the latter case, colouring materials may be added to the intermediate layers to produce a filter which intensifies the contrast of the image.

Title: Rotary steam generator
IPC: F22B5/00
Filed: 1925-05-05
Abstract: 247,044. Blomquist, J. V. May 5, 1925. Rotary boilers; feedwater, supplying and controlling.-Water is supplied to rotary, tubular steam generating elements 5 through a receptacle 3 which is in communioation at its upper part with the steam discharge pipe 6. The supply of water to the receptacle may be automatically controlled by a device operated by a float in the receptacle. To prevent the water in an element from falling below the level of the supply pipe 4 upon a rise of pressure, the supply pipe 4 is surrounded by a pipe 8 which, when the water level falls, places the upper part of the receptacle in communication with the boiler steam space. Alternatively, a throttle valve in the steam pipe 6 is opened by a float in the receptacle when the level falls. The supply pipe may extend downwards inside the receptacle and boiler. The speed of rotation of the elements is so controlled from the feed-control device that the speed is increased when the water level falls. Specifications 1218/76 and 193,417 are referred to.

Title: Bottle loading apparatus
IPC: B08B9/44
Filed: 1969-09-02
Abstract: 1279997 Feeding bottles between endless conveyers MITSUBISHI JUKOGYO KK 2 Sept 1969 [10 Dec 1968] 11739/71 Divided out of 1279995 Heading B8A A bottle loading apparatus comprises guide means 24 for guiding a row of bottles B from a bottle conveyer 10 to carriers 20 of a bottle processing apparatus, transfer means 128 for pushing the row along the guide means 24, and control means for stopping the drive of the bottle conveyer 10 for a preselected period of time after the transfer means has engaged a row of bottles on the guide means. As shown, bottles B on conveyer 10 are stirred by members 16 into respective lanes defined by guides 19. Plates 22 respective to each lane cause the leading bottles B to tilt forward, and the rows of bottles are successively picked up by transversely disposed bars 28a, 28b, 30a, 30b carried by endless feed-chains 26. The bars 28a-30b push the bottles B along guide channels 24 and thence into containers 20 of a bottle-processing machine 14. Since alternate rows of the containers 20 are in laterally staggered relation (Fig. 3, not shown), the channels 24 are carried at their downstream ends on a laterally oscillatable frame member 46. The ends of the latter are motivated by the action of peripheral cam grooves formed in cams 56, 56<SP>1</SP>rotating with the drive-shaft 32 of the feed-chains 26. The cam grooves engage pins 60 of arms 58 which are connected to the frame member 46. In order to support the bottles at the gap between the ends of the guide channels 24 and the mouths of the containers 20, rotating support plates 170 (Fig. 7A) are rotated into position and are rotated away from this position (Fig. 7B) in order to permit the passage of the bottle pusher bars 28a-30b through the gap. This is effected by a cam (180) on the shaft 32 and a suitable follower and linkage system (Figs. 5 and 6, not shown, 32 in Figs. 1 and 2 being shown as 132 in Figs. 5 and 6). In order to stop the conveyer 10 when it tends to deliver a bottle row too closely on the heels of the preceding row on the guide channels 24 the drive of the conveyer 10 is through a fluid-controlled clutch 296 (Fig. 9). An inflatable circumferential member 306 when pressurized from a fluid conduit 310 transmits drive from a permanently driven shaft 298 to a drive sprocket 302 of the conveyer 10. A cam (318) (Fig. 8, not shown) on the drive-shaft 32 of the feed-chains 26 operates a follower twice per revolution so as to energize a switch (32) in circuit with a solenoid-valve (322) in the pressure line 310. This causes the clutch 296 to be released and the conveyer 10 to be stopped momentarily at those points in the cycle where there is danger of the bottles of a row on the conveyer 10 interfering with the bottles of a preceding row in the guide channels 24.

Abstract: 108,373. Sterling Telephone & Electric Co., Bell, F. G., and Davey, W. C. Aug. 23, 1916. Mine signalling systems; order apparatus, - Relates to signalling keys particularly adapted for mine-signalling systems in which two circuits are employed. The key illustrated is particularly adapted for use in the system described in Specification 13062/14, in which the key, after giving the signals, drops and in so doing closes a second circuit. Fig. 2 shows the key in the signalling position. A heelpiece 7 on the arm 4 engages the end of the lever 13 pivoted at 14 which carries a leaf contact 26 adapted to engage a. fixed contact when the handle 6 is pressed towards the casing, the plunger 27 immediately returning it. On completing the signalling, the arm 4 is allowed to fall, the handle 6 being weighted to secure this. As the arm, which is forked as shown in Fig. 3, falls, a contact carried on but insulated from, the spindle 5 bridges a pair of contacts 10 and closes the second circuit either permanently or temporarily. The contacts 10 are mounted as shown in Fig. 5 so that contact is maintained even if the handle swings laterally
Patent GB-881955-A (GB)
Title: Process and apparatus for the preparation of titanium trichloride
IPC: C01G23/02
Filed: 1958-04-15
Abstract: Titanium trichloride is prepared by reacting titanium tetrachloride with an excess of hydrogen at 750 DEG -1700 DEG C. at atmospheric pressure and immediately thereafter chilling the products to a temperature below the sublimation temperature of the trichloride but not lower than the dew <PICT:0881955/III/1> point of any unreacted tetrachloride whereby the trichloride is separated as a solid from the remaining gaseous reaction products. The preferred H2/TiCl4 ratio is from 5-50:1, and the temperature is preferably above 1000 DEG  C. In carrying out the invention, hydrogen taken from a gas holder may be passed over copper supported on pumice at a temperature of 300 DEG -400 DEG  C. to remove oxygen and then dried with sulphuric acid monohydrate and phosphorus pentoxide to remove water before being mixed with titanium tetrachloride vapour.  The mixture is then preferably passed into the aparatus shown in Fig. 3 through an electrically heated metallic reaction tube 8 (or more than one tube may be provided) which may be of straight or helical form and housed in a container 9 filled with insulating material and having an inlet and outlet by means of which air may be displaced by an inert gas to protect the reaction tube against oxidation.  The tube may be constructed of stainless steel, molybdenum or an alloy of which the major constituent is nickel, depending on the temperature employed. The electrically conductive cross-sectional area of the tube preferably increases from the inlet to the outlet end: this may be achieved by increasing the thickness of the tube from inlet to outlet or by increasing the diameter of the tube from inlet to outlet without increasing the thickness.  On emerging from tube 8 the reaction gases encounter a perpendicular stream of hydrogen entering from pipe 15 whereby they are cooled to the desired temperature: the cooled mixture separates in the vessel 10, the walls of which are maintained by means of a jacket for a circulating liquid at above the dew point of titanium tetrachloride.  The solid particles are filtered from the mixture by means of a glass fibre cloth or other filter 11 which can be shaken by means of a device 14 to cause the trichloride to fall to the bottom of the chamber for removal.  The remaining vapours are led away to a condenser for recovery of unreacted tetrachloride, thence to a scrubber to remove hydrogen chloride and the hydrogen remaining is then returned to the gas holder.  Other filtering apparatus may be employed such as thermostatically controlled hose filters or cyclones coupled with electrostatic precipitators or separators.

Filed: 1929-04-18
Abstract: 321,903. Textiles (New Process), Ltd. Oct. 8, 1928, [Convention date]. Retting.-In the preparation of textile fibres suitable for spinning from cleaned waste vegetable material of any suitable type such as waste jute, the material, after it has been sorted according to the qualities of the fibre, beaten to remove dust and then washed in running water, is heaped and wetted with a solution containing 0.02 gram of olein or other fatty acid, vaseline, oil, or the like, 0.01 gram potassium nitrate, 0.01 gram of magnesium sulphate and 0.01 gram of potassium phosphate per litre, and heated to about 30 C. The material is left to ferment for 24-48 hours, then opened out, and scoured for 1 hour with 1 per cent solution of either caustic soda, sodium carbonate, magnesium chloride; or alkaline earths, ammonia or the like, or with the liquor resulting from a previous scouring operation. The ligneous products are thus dissolved. The fibre thus obtained is washed, bleached, then passed to a bath heated to 30-40 C. and containing for example 2.5 per cent soap, 2.5 per cent vaselines oil, 0.5 per cent alkali, the treatment lasting 1 hour. The fibre is then hydroextracted to leave 30-35 per cent moisture, passed into a wool carding machine, and flnally dried. Thus is obtained a white, curly, supple material.

Abstract: 916,624. Valves. CITROEN S. A., ANDRE. April 5, 1961 [Nov. 18, 1960], No. 12130/61. Addition to 854,716. Class 135. [Also in Group XXXII] An hydraulic distributer for use in apparatus for automatically levelling the frame of a motor vehicle comprises a body portion 1 comprising a pressure-fluid inlet connection 4, an outlet connection 5 to exhaust, and a connection 3 to the working pipe, a spool valve 2 determining whether the connection 3 is isolated, as shown, or is connected, according as to whether the spool is moved to the left or to the right, to one or other of the connections 4 and 5. The spool 2 extends at either end into chambers formed between the body portion 1 and diaphragms 6 and 6a, the diaphragms 6 and 6a being positioned, respectively, between discs 7 and 8, and 7a and 8a. Light springs 17 and 17a are interposed between the discs 7 and 7a and annular plates 15 and 15a respectively, pressing the latter against the body portion 1. The discs and diaphragms are positioned on each side between screwed members 10 and 10a and circlips 9 and 9a respectively and dust covers 11 and 11a are fitted on each side. Calibrated orifices 16 and 16a in the plates 15 and 15a register with annular grooves 13 and 13a in the body portion, the grooves being connected by a passage 12 which communicates through a passage 14 to a supply of liquid at atmospheric pressure. The member 10a is. shaped to facilitate connection to a control member. If the spool 2 is moved, say in the direction of the arrow f, the plate 15a is moved away from the body 1 by a shoulder 18a and liquid is forced through the throttling orifice 16 from the left-hand chamber into the right-hand chamber. The return flow of liquid is not impeded because the pressure of the returning fluid moves the plate 15 away from the body member, until the mid-position is reached. Similar conditions obtain when the spool is moved in the other direction.
