Filed: 1928-02-10
Abstract: 311,441. Barralet, T. E., Barralet, J. H., and New Geysers, Ltd. Feb. 10, 1928. Internally-fired boilers.-A water heater is of the type comprising a boiler and a storage vessel or tank, the upper end of the water heater being adapted to deliver hot water to the tank through a valve in a pipe which is extended to connect with the delivery pipe, the lower ends of the boiler and storage being connected. The boiler comprises a geyser of the tubular or chamber heating type fitted with fins or conductors on the heating surface as described in Specification 187,674. In the example the outflow pipe c from the geyser delivers normally to the tank b through the valve f. On drawing off at any tap l the valve f closes and, if the water in the tank is cold, all water pases through the geyser and pipes c, g to the distributing pipe j. If the water in the tank is hot, a light valve i at the junction of the delivery pipe with the tank and with the pipe g, opens and water is drawn from both the geyser and the tank.

Abstract: 667,325. Holders for photographic or X-ray sensitive material. METROPOLITANVICKERS ELECTRICAL CO., Ltd. (General Electric X-ray Corporation). Feb. 20, 1950, No. 4316/50. Class 98 (i). A holder frame or cassette comprises a pair of thin, rigid, separable plates which secure a sheet of photographic sensitive material placed between them for exposure to light or to rays such as X-rays, one plate having at least a part transparent to the rays by which the exposure is effected, together with magnetic means whereby the plates are lightly hold together in closed position but so as to permit easy separation. When the exposure is made by X-rays or like radiation both sheets are opaque to light, and light sealing means form a pocket for the sensitive material. As shown, an X-ray cassette comprises plates 12, 13 hinged at 14 and preferably made of non-magnetic material. Plate 13 is made of material permeable to X-rays, such as the reaction product of phenol and formaldehyde; plate 12 may be made of aluminium. A channel member 16 fixed to plate 13 forms a pocket 20 in which a sensitive sheet is laid, and which is closed by an interfitting rib 18 on plate 12 when the plates are brought together. One or more magnets on one plate and an armature on the other hold the plates together ; e.g. magnets 24 are mounted in recesses in the channel member 16, and rib 18 is made of iron or other magnetic material. The cassette is opened by prizing the plates apart with a wedge or like tool, or by placing it in a neutralizing magnetic field. A layer of lamb's wool may be fixed to one plate to press the sensitive sheet, together with intensifying screens, if desired, against the other plate.

Title: Differential or balance mechanism
Filed: 1937-02-03
Abstract: 471,325. Differential gearing. LFIELD, R. J. Feb. 3, 1937, No. 4497. [Class 80 (ii)] A differential mechanism comprises a planet carrier and casing 12 driven through bevel gearing 11 and co-axial internally-toothed driven wheels 16a, 16b on the half-axles 17, 17. The planets comprise pairs of intermeshing pinions 13a, 13b which also mesh respectively with the driven wheels 16a, 16b. For limiting the differential effect and preventing the half-axles 17, 17 from being driven at different speeds the ratio of the greater to the less of which exceeds a predetermined value, two additional gears 26 on sleeves 20a, 20b are provided which are geared to the planet pinions 13a, 13b respectively, and are prevented from backward rotation by one-way locking devices (not shown) coacting with adjacent surfaces 21 on the outer ends of the sleeves 20a, 20b. Thus for equal speeds of the axles 17 and for speeds within the predetermined ratio the sleeves 20a, 20b rotate freely in a forward direction. When this speed ratio is exceeded however, the sleeve co-operating with the faster moving axle tends to rotate backwards but is prevented from doing so by its respective oneway locking device. Thus the normal differential effect is allowed for, but an excessive differential effect such as "spinning" is prevented. The locking devices which are associated with a stationary part may include a common outer member and provision may be made for releasing the locking devices to allow of a drive in the reverse direction when required. In a modification, one of the driven axle gears comprises a sun pinion and stepped compound planets are used. In another modification, the planet carrier is secured to one of the driven axles and the driving element comprises an internal annulus.

The main supporting framework of a domestic wringing or mangling machine comprises a single horizontal member 10 having at each end thereof, an integral bearing 18 for the lower wringer roller 20 as well as an upwardly extending rod 23 secured therein, these rods receiving slidable bearing blocks 35 for the upper wringer roller 32. The member 10 comprises a combined water-collecting trough 11 and mangling board 12 formed as a one-piece metal die-casting, and water falling into the trough is directed by channels 14 to a central drain outlet 13. The rods 23 are secured by force fitting them in apertures in the bearing blocks, each rod including a conical portion 27 received in a complementary portion in the block. To give added security the rods 23 may also include a fluted or knurled region 26 which is arranged so as to cut its way into the metal of the block. The spindle 33 of the upper roller 32 is received in inverted U-section channels 34 in the bearing blocks 35. The rollers are urged together by springs 40 located between the bearing blocks 35 and inverted cup-shaped portions 38 of a bridge member 39 held in place by adjustable nuts 37 screwed on to the rods 23. The roller spindles carry at their ends intermeshing pinions 41 which may be covered by means of shields formed with the upper bearing blocks as onepiece die castings. Fig. 4 (not shown). The machine may be supported by means of screw clamps 29 secured to extensions of the rods 23.

Title: Improved Mechanism for Effecting the Automatic Opening and Closing of Gun Breech Blocks of the Wedge Type.
Inventor: SCHNEIDER EUGENE
IPC: F41A5/36
Filed: 1916-03-28
Abstract: 124,788. Schneider, E. March 28, 1916. Ordnance breech mechanism.-Relates to semi-automatic breech mechanism for opening and closing breech-blocks of the wedge type by means of energy derived from a hydro-pneumatic recoil brake. According to the invention, the breech-block is connected to a piston working in a cylinder formed within the piston-rod of the brake piston, this cylinder being closed at its forward end and connected at its rear end to the body of liquid in the brake. The action is such that the energy for opening the breech acts during recoil and the energy for closing when the gun has run out, the breech-block being, in each case, rendered free to move by the automatic removal of a locking- bolt. Fig. 1 sbows the piston E of the hydro-pneumatic recoil brake connected to the gun slide B through a hollow piston-rod D, the brake cylinder being carried by the gun A. The breech-block C, which is held in the open and closed positions by the engagement of a spring bolt. J, with recesses c<2>, c<1>, Fig. 3, respectively, is connected through a bell-crank lever I, H and rod G to a piston F working with clearance in the interior of the rod D. The action is such that, during recoil, the bolt J is withdrawn from the block by a spring-controlled lever k on the gun slide, Fig. 3, and the breech opens owing to the weight of the block, assisted by excess fluid pressure on the rear side of the piston F. On the run-out, the lever k is tripped, the breech remaining open until the loading position is reached. The rocking of the extractor arms P, during loading, automatically withdraws the bolt J from the recess c<2> and allows the block to close bv the excess pressure on the forward side of the piston F.

Divided out of and addition to 459,833 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 12, 1937. [Class 83 (iv)] [Also in Group XXX] In delivering work from a rolling-mill to the undriven rollers 10 of a table C and passing it back over the top by driven endless chains 12 of a rising table D as described in the parent Specification, the receiving table C is coupled to rise as well as the delivering table D so that the time of feeding back the work when the chains 12 rise above the rollers 10 can be more suitable. The driven toothed quadrants 17, through levers 16, first raise the feed table D, on which the receiving table C is mounted, but the extension of the lever 16 to links 25, 26, 27 slows down this vertical rise of C as desired so that the chains 12 rise above the rollers 10 and pass the work back. Similar tables with required modifications are provided on the other side of the mill for the receiving and feeding in to the rolls. In an alternative construction, the two tables on the exit side may be lifted in unison for some distance, after which the receiving table may descend while the feeding table D continues to rise. Specification 466,843 is referred to.

Abstract: 267,294. Stone & Co., Ltd., J., and Darker, A. H. Feb. 19, 1926. Supplying consuming devices from variablespeed generators. - In train lighting systems which include electromagnetic switches for retaining lighting switches closed only when the batteries are in charged condition, a hand switch is incorporated for controlling the electromagnetic switch and also for controlling the consuming circuit. The bar switch b is shown in the off position. On being pulled over, the slipper c engages the terminals d, d' and completes the circuit of the half lights L<1> and the slipper c<1> engages the terminals e, e<1>, to close the circuit of the pull-on coil f with the battery B but is not strong enough to bring the brush g on to the contacts h, j for completing the circuit of the remaining lamps L. When the train is in motion the cut-in switch C connects the dynamo D with the circuits and energizes the auxiliary coil k so that it together with the coil f is able to close the brush g and bring in all lamps. These remain on when the train comes to rest, until the battery voltage drops and the coil f loses power to hold the brush. when the lamps L will cut out. By providing additional contacts on the bar switch, it is possible to change from the full-lights to the half-lights condition without passing through the no-lights condition. Alternatively the control of the half lights by the bar switch may be made dependent upon the magneto switch. Specifications 180,049 and 260,334 are referred to.
