Patent GB-403837-A (GB)
Title: Improvements in underfeed stokers
IPC: F23K3/14
Filed: 1932-07-15
Abstract: 403,837. Screw fuel-feeders. IRON FIREMAN MANUFACTURING CO., 984, East 17th Street, and CARTER, H. C., 1424, Reed Collage Place, both in Portland, Oregon, U.S.A. July 15, 1932, No. 6721/33. Divided on 395,516. [Class 51 (i).] In an underfeed stoker having a fuel feed duct 35 connected to a fuel magazine or hopper 27 and a feed worm 34 for moving fuel from the hopper through the fuel feed duct, the removal of foreign substances in the fuel is facilitated by the provision of an inclined surface or surfaces at the junction of the hopper and the feed duct, to engage and elevate the foreign substances. The inclined surface is provided on an end part 137 projecting into the hopper around the worm 34, so that foreign substances are moved upward towards a zone below a removable cover 140 provided at the top side of the fuel duct at its junction with the hopper. The part 137 and the cover 140 form parts of a separate section 133 of the feed duct. The cover 140 has a lug 143 projecting into the hopper so that any foreign substances which cannot pass along the feed duct are caught up thereby, so as to localize jamming to the region of the cover. The fuel screw 34 is driven by an electric motor through the medium of planetary selective gearing which co-operates with means for interrupting the drive when an overload occurs on the feed screw. The motor drives, through intermediate transmission, the shaft 85 to which the gear wheel 87 is pinned. A cage 76 carries three planetary gear wheels 75 all in permanent engagement with a central pinion wheel 77, which is connected to the feed screw by intermediate gearing. Two of the gear wheels 75 each has a coaxial pinion 86, and the third has an extra wide face forming in effect a pinion of the same size as the gear wheel. Any one of the pinions can be brought into engagement with the gear wheel 87. The cage 76 is formed with alternate shallow notches 79 and deep notches 78 with inclined sides 102. A hooked arm 80 pivots in the casing 63 on a shaft 81 on the outer end of which is pinned a hand lever 82 spring-urged upwardly so that the arm 80 normally engages one of the notches 78, 79. When one of the pinions 86 is in engagement with the gear wheel 87, the arm engages one of the notches 78. When an overload occurs, the pinion 77 stops, so that the cage 76 tends to rotate about the pinion 77. This forces the arm 80 out of engagement in the notch 78, lifts the arm 82, rotates a lever 91 which actuates a switch 94 so as to ring an alarm bell 98, light a warning lamp 99, and open a switch 100 so as to break the motor circuit. The momentum of the cage is sufficient to carry it to a position in which the arm 80 engages in a notch 79. To re-set the gears, the hand lever 82 is depressed and a dial 76a operated.

Patent GB-491797-A (GB)
Title: Improvements in or relating to combing machines
IPC: D01G19/14
Filed: 1937-03-08
Abstract: 491,797. Combing-machines. NASMITH, J. W. March 8, 1937, No. 6744. [Class 120 (i)] In a combing - machine each detaching roller D, D', Fig. 1, rotates intermittently in one direction only and the upper roller D moves bodily upon the lower roller D<1> towards and from the nipper, the upper piecing roller P<1> serving to clear the roller D during substantially the whole operation of detaching and piecing and the nip point of the piecing rollers P, P<1> being movable to direct a backed-off end substantially vertically downwards when backing off ready for the next piecing. The detaching roller D<1> is mounted in fixed bearings and rotates intermittently in the forward direction only, the top roller D being rolled to and fro thereon as described in Specification 16001/01, [Class 120], by movement of the weight hook 1 mounted adjustably on the bar 2. The lower piecing roller P and carrier roller C are mounted in a block K which slides in the framing F and is reciprocated from a shaft 7 through levers 8, 9, 11. The top piecing roller P is carried by a lever L having a slot O engaging a bowl 14 carried by a stud 13 secured to an arm 12 cast on the slide F, and is urged to the right, Fig. 1, by a spring 17. An adjusting ring as described in Specification 377,003 is carried on the axis of the roller P<1>. At the end of the detaching period the rear end of the detached fleece is at T, Fig. 2. The roller P remains in close proximity to the roller D<1> during the whole or the greater part of the detaching. When completed or nearly completed the slide K is drawn to the left allowing the roller P<1> to roll round P until the screw W contacts with the bowl 14, and then fall behind the roller P which does not rotate during its withdrawal. The slide block K reaches the position of Fig. 3, dwells there, and then the reverse rotation commences in the direction of the arrows. This directs the fleece delivered backwards tangentially downwards well clear of the cylinder cover 19. The roller P moves back to its original position, Fig. 4, while the reverse rotation is being completed. The direction of rotation of the roller P is again reversed and the front end of the on-coming tuft T<3> pieced on to T<2>, the roller D being clear of the path of the rising roller P<1> and then rolling back over the roller D<1> and pushing the lever L back to the position of Figs. 1 and 2. Specification 2109 /83, [Class 120], also is referred to.
Patent GB-615912-A (GB)
Title: Fuze
IPC: F42C15/20
Filed: 1946-03-05
Abstract: 615,912. Projectile fuzes. AMP CORPORATION. March 5, 1946, No. 6841. Convention date, Oct. 4, 1945. [Class 9 (i)] An ammunition projectile fuze includes a gyroscopic rotor 13 containing a detonating charge, the rotor being normally set as in Fig. 1 with its gyroscopic axis in a median angular position with respect to the axis of the fuze body, but being capable of being set into two other positions. When set in one of these other positions, Fig. 5, the rotor will precess, when the projectile is in flight, to a position in which a quick-acting detonator will be struck by the firing pin 53, and in the other position a delay action charge D, Fig. 9, will be similarly brought by the gyroscopic action of the rotor to a point opposite the firing pin. The parts of the fuze in front of the rotor are similar to those in Specification 615,640, and include a hollow striker 67 mounted in a conical bore 39, a sleeve 35 surrounding the firing pin, and centrifugally operated locking slides 43 all as in the earlier Specification. The sleeve 35 engages a groove 18 in the rotor, this engagement serving to limit the setting movements of the rotor. As shown in Fig. 9, the rotor has a groove 21 engaged by a tongue 22 on a spring- pressed key 23, the latter having tongues 81 engaging in slots 85 of a member 24. In a diametrical bore 108 of member 24 is a plunger which is urged by a circumferential spring 113 into cam grooves, three in number, in the fuze body 101, such grooves serving to hold member 24 and hence the rotor in any of its three positions. The rotor is set by inserting a flat tool through the thin part 104 of the fuze cover 91 and into a slot 107 of the member 24, the tool being then turned one way or the other according to the required setting of the rotor. The outer two of the three grooves for the plunger in the bore 108 are so deep that the inner end of the phmger moves clear of the stem 26 of the key 23, thus allowing the latter to move clear of the rotor when the projectile is in flight. Specifications 615,625 and 615,972 also are referred to.

Title: Improvements relating to densitometers
Inventor: BURNS HAROLD
IPC: G01N9/00
Filed: 1957-03-04
Abstract: 827,234. Measuring specific gravity. SIMMONDS AEROCESSORIES Ltd. March 3, 1958 [March 4, 1957], No. 7097/57. Addition to 786,113, [Group XX]. Class 40 (1). [Also in Group XX] The densitometer of the parent Specification is compensated for changes in ambient temperature by making the supporting element(s) of a metal whose modulus of elasticity changes with temperature in the opposite sense to the changes in the dimensions of the apparatus. A suitable metal is the ferrous alloy containing Ni + Co 41-43% (Co alone up to 1.0%), Cr 4.9-5.5%, Ti 2.2-2.6%, Al 0.3-0.8%, Si up to 1.0%, Mn up to 0.8%, C up to 0.06%, S up to 0.04% and P up to 0.04%. This alloy can, by suitable heat treatment, be given any desired positive coefficient of modulus of elasticity. A preferred construction is shown, comprising a one-piece non-magnetic yoke 200 containing soft or permanently magnetic arms joined by permanently magnetic cross-members 203, 204. The ends of the yoke are joined by a rigid member 205. The hollow member 1 containing the liquid under test vibrates in the plane of the arms and generates signals in the coils wound on the arms. The resilient tubes 2<SP>1</SP>, 3<SP>1</SP> conducting the liquid to and from the hollow member, which also serve as supports for it, are made of the alloy specified above. According to the Provisional Specification this method of temperature compensation can be applied to other types of densitometer, e.g. of the torsionally oscillating or tuning fork type.
