IPC: F02M57/02
Filed: 1927-12-23
Abstract: 311,834. Dehn, F. B., (Oil Engine Development Co.). Dec. 23, 1927. Cylinders receiving liquid fuel.-Air is compressed through an orifice 41 into a cavity 40 in the piston during the instroke, and escapes at the end of the stroke through the same orifice 41 against fuel issuing from a nozzle 24. The fuel is, as described in Specification 237,915, first drawn, with air from the cylinder, past a needle valve 16 into a chamber 19, by the upward movement of a plunger 11, and the aerated fuel is then ejected into the cylinder by the return of the plunger 11. To cool the chamber 19 an inner member 13 is made of a good heatconducting material-e.g. aluminium-outer protecting members 14, 15 being made of steel or a metal having low heat conductivity. An annular space 23 and radial grooves leading to a central orifice 18 are provided for the fuel between the members 13, 14. The cavity 40 may be formed as shown by an annular member 32, which is screw-threaded into the piston face, a locking washer, having lugs 35, 38, turned up and down, being provided; alternatively the annular member may be closed at its inner end and locked by a pin driven into the piston.

Abstract: 783,441. Feeding webs. ROSE BROS. (GAINSBOROUGH), Ltd. Dec. 1, 1955 [Dec. 3, 1954], No. 35003/54. Class 100(1) '[Also in Group XVII] In a machine in which wrappers 12 are severed in succession from a web 11 and each wrapper is folded around a blockshaped article 18 in the form of a tube with an overlapping seam, the web-feeding and severing mechanisms are mounted in a common framework which is pivotally mounted for adjusting movement about an axis normal to the plane of the web when in position to be severed and means are provided for adjusting the framework to correct any observed misalignment of the overlapping edges of the wrappers. The web 11 is fed from a supply roll 19 by rollers 21, 22 and passes over a loop-forming roller on a pivoted arm 23 to further rollers 26, 27 which feed it through severing-mechanism 13 on to a supporting platform 14. The roller 27 is periodically disengaged from the roller 26 so that the web is stationary during each operation of the mechanism 13. The latter and the various rollers are all mounted in a framework 38 which is pivoted on a shaft 39 journalled in the machine frame 41 and carrying bevel gears 29, 30 by which drive is transmitted from a shaft 28 to gearing driving the rollers 21 and 26. A slotted quadrant 42, extending from the framework 38, is secured by a bolt 43 to a lug 44 on the frame 41, the bolt being engaged by adjusting screws 46 passing into the slot. Adjustment may be effected without stopping the machine by slackening the bolt 43 and turning the screws 46 until it is observed that the edges of the wrappers are aligned when folded on to the articles 16.

Abstract: 455,745. Rudders and steering-gear. FAIREY AVIATION CO., Ltd., North Hyde Road, Hayes, Middlesex, BOLTON, F., 22, Shanklin Road, Southampton, DUNSFORD, C. G. J., 94, Merton Avenue, Hillingdon, Middlesex, and HAND, P. G. E., Dorian, Thornhill Park Road, Southampton. Dec. 18, 1935, No. 35107. [Class 114] A water rudder for a flying-boat or sea-plane of the kind in which the rudder is mounted on a horizontal axis so that it may be raised for housing is constructed with a main portion carrying an auxiliary portion, the latter being coupled to the operating mechanism and providing a servo-actuation of the main portion. The rudder 14 is provided with an auxiliary portion 15 pivoted thereto and coupled by a control bar 16 with the pilot's control. The assembly may be raised about a horizontal axis by tricing lines and housed in a divided stock 12. Where air pressure is utilized the pilot operates by his control bar 28 upon valved connections 25, 26 which are in communication with an air pressure reservoir 20. In an alternative form, the assembly is mounted in a tubular member 44 which in turn is supported in a ball mounting 43 in the hull of the float or sea-plane. The main rudder 45 is carried by a bossing secured to the tube 44 and in turn has pivotally mounted thereon the servo-flap 46. This flap is connected by levers 56 and 54 with a pin 52 forming part of the rod 49 of an air pressure piston. For steering the pilot controls the air pressure to the cylinder 47 and so operates the servo which in turn causes a movement of the main rudder 45. The assembly is completed by a cylinder and a piston which is also under the control of the pilot and which normally by reason of the spring 71 maintains the apparatus in the housed or upper position. When required for steering pressure is admitted beneath the piston 65 and the apparatus rotates about the ball joint to lower the rudder 45.

Title: Improvements in textile yarns and fabrics and the production thereof
IPC: D01H13/30
Filed: 1934-12-07
Abstract: 448,621. CrÛpe twisting of yarns. DREYFUS, H., 22, Hanover Square, London. Dec. 7, 1934, No. 35191. [Class 120 (iii)] Crepe yarns are prepared by twisting yarn, particularly yarn of an organic derivative of cellulose, and concomitantly with such twisting apply steam intermittently to at least part of the yarn actually receiving twist, under conditions such that moisture is present. For example, the yarn may be passed through a steam chamber and steam admitted through a valve which is opened and closed at intervals. Again, the yarn may be moistened at intervals and subjected to a dry steam treatment, the effectiveness of the treatment being thus confined to the moistened portions. The product is a yarn in which intermittent portions are smooth and cylindrical and have an apparent specific gravity more than 85 per cent of the actual specific gravity of the filaments. In the apparatus shown, the yarn drawn over the head of a twisting bobbin 7, and moistened if desired by means of a roller 39, passes in contact with two cams 16 between which is disposed a steam chamber 11 slotted lengthwise at 14. The yarn is finally wound on bobbins 8. The action of the cams is to move the yarn intermittently into and out of the steam chamber through the slot 14. Moist steam is supplied through a connecting pipe 13 from a header 12. In a modification (not shown) the yarn on its passage from the twisting bobbin to the winding bobbin passes through a steam tube, supplied with steam from a suitable source, connected through a cam-controlled valve to a suction pipe, the suction being sufficient when the valve is open to remove all steam from contact with the yarn. Specifications 358,585, 437,019, 438,590, and 440,653 are referred to.

[Classes 72 and 82 (ii).] In a process for carburizing or nitrogenizing ferrous or ferrous alloy articles, the articles are contained within a perforated basket 28 mounted within a retort 13 which is detachably mounted within an electric furnace 1. The retort 13 is provided with an external flange 7 which fits into a sand seal 85 in a trough 10 mounted on the top of the furnace 1. The retort is closed by a heat-insulated cover 17 which is secured by bolts 16 to, and separated by a rubber gasket 15 from, the flange 7. Mounted on the lower end of a shaft 19 is a fan 26 which directs the carburizing &c. gas, admitted to the retort 13 by a pipe 47, past the apertured top 29a of the container 28 and down between the latter and the retort 13 before passing through the perforations into the container 28, and acting on the articles therein. The gas leaves the container by the opening 29 in the top 29a and passes out of the retort by a pipe (not shown). A motor 20 mounted on the shaft 19 is supported on legs 43 which are secured to the cover 17 and a second fan 25 is mounted on the shaft 19 for the purpose of cooling the bearing 21. In a modification, the container 28 is composed of a nest of perforated boxes which fit on top of each other and are secured in position by bolts. The Specification as open to inspection under Sect. 91 states that the apparatus may be used for barffing steel or for annealing steel in an inert atmosphere such as hydrogen or non- ferrous metals such as copper in an atmosphere of steam. This subject-matter does not appear in the Specification as accepted.
