Title: Improvements relating to fuzes for projectiles or the like explosive missiles
IPC: F42C19/04
Filed: 1956-04-30
Abstract: 782,257. Ammunition fuzes. AKTIEBOLAGET BOFORS. April 30, 1956 [May 7. 1955], No. 13189/56. Class 9(1) A direct-action percussion fuze having a stem 1 to be screwed into a projectile has a conical nose divided into two parts 3, 4 through which extends an axial passage 5 housing a sleeve 7 having screwthreaded engagement with the part 4 and a shoulder engaging the part .3. At the junction of the parts 3, 4, the sleeve has an annular line of fracture 10. A plunger 12 extends through the part 4 and carries at its outer end a disc 11. From the inner end of the plunger, a striker rod 13 extends through the sleeve 7 and is adapted to strike an ignition composition (not shown). If, on impact, the disc 11 hits the target, the disc is driven inwards to actuate rod 13 through the plunger 12. If impact of the projectile is oblique, the sleeve 7 fractures and the part 4 falls off. A spring 8 bearing against a flange 9 on the slower part of the sleeve 7, which sleeve bears against a collar on the rod 13, drives sleeve 7 and hence rod 13 to initiate the fuze as before. In a modification the spring 8 is omitted, the impact of the part 3 being relied on to produce inward movement of the rod 13. In Fig. 5, not shown, the parts 3, 4 are held together before impact by screws 15, 16 each having a fracture line, so that on impact the part 4 is released. The rod 13<SP>1</SP> is locked by a sleeve 18 having a flange engaging a spring 21 and threadedly engaging a second sleeve 20 which extends into a third sleeve 22 supporting the spring 21. Balls 24, 25 housed in the sleeve 20 engage a groove in the rod 13<SP>1</SP>. On separation of the part 4 from the fuze, the spring 21 moves the sleeve outwards, the balls 24, 25 are then freed, whereupon a spring 27 drives the rod 13 inwards. Instead of screws, the parts 3, 4 may be held together by adhesive or by a circumferential band, preferably of metal, the edges of which enter grooves in the parts 3, 4 respectively.

Title: Rotary drum for a sorting machine
IPC: B07B1/22
Filed: 1976-04-01
Abstract: 1490053 Screening apparatus SOC FRANCO-EUROPEENNE DE MATERIEL POUR L'INDUSTRIE ALIMENTAIRE 1 April 1976 [2 April 1975] 13206/76 Heading B2H A rotary drum 1 for a sorting machine for green beans has fixed and movable bars 8 and 5 whose spacing is adjustable, the movable bars 5 being displaceable in radial slots 3 and being urged by resilient means 9 towards a limit position therein, a cam follower 15 freely slidable on each movable bar 5 and urged into contact with a camming surface 14 by the resilient means 9, and means for sliding each cam follower 15 along its bar 5. The sliding movement of the cam follower 15 is imparted thereto by forked members 17 mounted on a ring 20 which is slidable parallel to the axis of the drum on guide blocks 21. The position of the ring 20 may be adjusted by a handwheel 27 attached to a spindle 25, the latter being provided with idle rollers 24 which are in rolling engagement with a flange 23 on the ring 20. Thus movement of the handwheel 27 causes each cam follower 15 to slide on its bar 5 and results in a movement of each bar 5 in its slot 3 and thus adjustment of the spacing between the bars 5 and the V-shaped fixed bars 8. The rollers 24 together with rollers 36 allow the spindle 25 and its associated parts to remain stationary while the drum I rotates and thus permits the adjustment to be effected while the machine is in use. When the bars 5 are in their uppermost position during operation, they are moved away from the bars 8 by a camming surface which engages rollers 7 on the bars 5 to free any articles which may be jammed between the bars 5 and 8.

Abstract: 884,535. Malting. CHEVALIER, H. M. J. April 21, 1959 [April 22, 1958], No. 13504/59. Class 14 (2). [Also in Groups XIII and XXX] In apparatus for malting, drying or kilning grain, the material under treatment is circulated continuously within a compartment a 1 , Fig. 1, while resting on one or more perforated rigid platforms 10 inclined such that the material descends by its own weight at a predetermined speed under the influence of transverse angle members 50, Fig. 4, sliding on the platform in a downward direction. Grain, previously moistened when the treatment is malting, fed by a screw conveyer on to the platform 10 slowly descends thereon over an air box 18 delivering air through the perforations at the required temperature and humidity; on reaching the bottom of the platform, the grain is undercut by a " porcupine " and then fed through a further screw conveyer to, preferably, the next higher compartment, and so on. Blocking of the perforations by grain is prevented by fitting brushes 54, Fig. 4, between the flanges 51, 52 of the angle members 50. Heating and cooling, according to requirements, of the air, which is circulated and partially recirculated by a fan 40, is achieved by heat exchangers 42 through which heating or cooling fluid is circulated via a two-way pipe 43 (shown diagrammatically in Fig. 1). The effective flow-section of the air is adjustable by slide valves 45<SP>1</SP> and 39, and loss of air in the space between succeeding angle members is avoided by the provision of sprung rubber strips 48, 49. In Fig. 2 (not shown), the angle members do not project beyond the width of the platform 10 so that the partitions 21, 22, shown in Fig. 1, can be directly connected to the platform 10.

Filed: 1971-05-06
Abstract: 1306617 Producing tungsten CARMET CO 6 May 1971 [8 May 1970] 13567/71 Heading C7D [Also in Division C1] Tungsten powder is prepared by reducing a tungsten compound, preferably ammonium paratungstate, to tungsten oxide and then reducing the oxide with dry hydrogen gas passing through a reduction zone in the same direction as the passage of the oxide therethrough. The dew point of the hydrogen gas should not be higher than -30F, and the tungsten compound should not contain more than 100 ppm total of the elements sodium, potasium and calcium. In an example, ammonium paratungstate is calcined in an atmosphere of ammonia at 1000-1150F to give a blue tungsten oxide, of average particle diameter 11 to 14 microns; the tungsten oxide is loaded in molybdenum boats and passes through a reduction furnace at 1300-1650F, while dry hydrogen flows concurrently through the furnace, to give tungsten powder average particle size 1À05 microns. In a subsequent step, the tungsten can be carburized to give a friable tungsten carbide powder

Title: Improvements in the manufacture of elastic fabrics and in circular knitting machinesfor producing the same
IPC: D04B1/18
Filed: 1935-05-09
Abstract: 455,931. Knitting. BLACKBURN & SONS, Ltd., G., Kirkewhite Street, Notting- ham and TOWERS, E. J., 11, Clifton Road, Ruddington, Nottinghamshire. May 9, 1935, No. 13650. [Class 74 (ii)] An elastic or inelastic weft thread E is carried backwards and forwards over a predetermined width a-b of a tubular fabric. The thread is laid by a feeder F reciprocating on a bed H concentric with the needle cylinder. The needles N at each end of the space a-b have long butts which are engaged by a special set of cams on the revolving cam ring B, and they are thus raised far enough to take the thread E, without clearing their loops : this thread is subsequently secured by the loops of the course knitted by the next ordinary thread carrier and its associated cams. The feeder F is carried by, and can reciprocate radially in, a block G slidable on the bed H formed with a slot H<1> through which depends a pin K from the feeder. At each end of its stroke the feeder F is moved radially outwards by reason of the outwardly inclined portions H<2> of the slot H<1>, so as to remove its thread from the needles and to move it out of the path of the following ordinary feeder. The feeder F is moved from a to b by engagement with the pin K of an arm J revolving with the cam ring B, and is returned to a by a band M wound on a drum L which is revolved by the interengagement of a pinion S on the drum and a rack O. The arm J and rack O are carried on a pillar P, and rotatably mounted on this pillar is an arm Q. A stud Q<2> on the pillar P engages a helical slot Q<3> in the arm Q. Rotatably mounted on a second pillar P<1>, is another arm Q<1>, connected by pinions R to the arm Q. Thus, by a pattern controlled tappet which revolves one or other of the arms Q, Q<1>, the rack O may be lowered into engagement with the pinion S, whilst simultaneously the arm J is lowered out of the path of the pin K, or both rack O and arm J may be simultaneously raised. Should the band M break, another arm V provided on the cam ring engages the pin K and returns the feeder F to the end of its slot so as to avoid the next ordinary feeder. Elastic thread is also introduced' at one or more ordinary feeders. An elastic weft may be used to produce elastic areas in a non-elastic fabric, or to reinforce the main elastic thread, whilst, by using a non-elastic weft E, the elasticity of a fabric may be neutralized in certain areas. It is stated in the Provisional Specification that all the needles in the space over which the extra thread is to extend may be provided with extra long butts.
