Abstract: 615,283. Windscreen wipers. TRICOFOLBERTH, Ltd., and BAYES, C. A. July 30, 1946, No. 22708. [Class 138 (i)] The wiper blade of a windscreen wiper is so attached to its actuating arm, which arm is mounted on an oscillatable spindle, as to be sweeping through a greater angle than that swept by the. arm, and the blade is urged into a central position in alignment with the arm by means of a spring of hairpin-like form of which the bridge is connected to the end of the arm and the free ends are engaged in a sleeve which is attached to the blade. The metal holder 2 of a wiper blade 1 is attached to the wiper arm 3 by means of a flat pin 6 passed through the bore of a resilient grommet 5 secured in an aperture of an extension 4 of the arm, the holder being loosely engaged by the pin to allow sideways swinging of the blade at the end of each stroke, and also turning movement about the pivot 6. A hairpin spring 10 has a raised bridge portion 9 passing through a hook 8 on the extension 4, and two free ends 11 secured between the holder 2 and a sleeve 14 embracing it. Towards the end of each stroke the blade abuts the edge of the screen and pivots out of alignment with the arm to lie along the edge of the screen, and during the next stroke the spring 10 returns the blade and arm into alignment, the tension of the spring being adjustable by sliding the sleeve 14 along the holder 2.

[Class 135] A safety-valve particularly adapted for use on coke-boilers and like domestic heaters has the loading means located within the valve casing and has means operable from outside the casing to lift the valve member from its seat for testing purposes which means cannot be used to increase the loading on the valve. The valve member has a narrow chamfered seating surface 28 formed by first turning the valve with a face at 45‹ and backing this off above and below at angles of 60 and 30‹ respectively. The valve spindle which has guide wings 27 engaging the valve casing above the seat passes through a central aperture in a cap 14 screwed in the casing. The loading spring 21 is arranged between this cap and a washer supported by the guide wings and is adjusted by screwing the cap more or less into the casing the inward movement being limited by a stop ring 20 inserted between the cap and a shoulder on the casing. A cover provided with a manipulating head 22 slidably mounted on the valve spindle, normally rests on the cap 14 but may be lifted to cause a removable transverse pin to engage the upper end of a slot in the valve spindle and lift the valve from its seat. A seal 24 may be fitted to hinder the removal of the pin 23.

Abstract: 464,510. Wrapping - machines. DIKANSKY, L. Aug. 14, 1935, No. 22890. [Class 94 (i)] In a wrapping-machine for forming packages with twisted ends of soft articles such as fruit, a web of thin or tissue paper is guided over a former by one or more endless belts to form it into a tube, and an article is inserted into the tube, which is subsequently twisted. As shown, the articles to be wrapped are contained in a funnel t, Fig. 2, and are controlled and allowed to fall singly by pivoted arms r<1>, r<2> having rollers r, q at the ends, and resiliently mounted so as to have a slight relative movement. The wrapper F passes from a spool f and is formed into a tube with overlapping edges by an endless belt n, Fig. 12, passing twice over a roller b and over pulleys p<1>, p<2>, s<1>, s<2>, w<1>, w<2> so arranged that the downward runs from the roller h to the pulleys w<1>, w<2> drape the paper around the lower cylindrical end of the tube z. The paper tube is initially twisted at the end k, Fig. 2, and the jaws d of a rotary gripping device close upon the article m which has been dropped into the tube. Gripping devices comprising jaws a, a<1> and half collars b, bl are mounted above the jaws d. The jaws d having gripped the article, move downwards while performing their rotary movement, and the jaws a, a<1>, b, b<1> approach sufficiently close to be capable of supporting the next article. The jaws d are again rotated and rise to compensate for the shortening of the wrapper due to twisting. Dies c carrying knivesnow approach and sever the wrapper between the articles, and the jaws d are opened to discharge the wrapped article.

Abstract: 710,287. Generating combustion products under pressure. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 2, 1951 [Oct. 3, 1950], No. 22928/51. Class 51 (1) In an air-jacketed type of combustion chamber for burning fluid fuel under pressure, for example for use in a gas turbine plant, in which the flame tube is built up of telescopic sections disposed along the length thereof, the downstream end of a flame tube section 4 comprises a radially inwardly extending portion 21b and an axially extending portion 21c which projects into the upstream end of the adjacent downstream section 5 so as to define an entrance opening of substantially cylindrical cross-section of a louvre passage for cooling and insulating air flow from the surrounding air space 2a. The outer surface 22 of the upstream end of the downstream section 5 is bevelled to avoid baffle action. The flame tube sections also have openings 14 for admission of combustion air from the surrounding air space. The flame tube sections are supported by a plurality of resilient brackets 15, and are supported co-axially with each other by means of brackets 16 on one section which cooperate with brackets 17 on the adjacent section. The upstream end of the flame tube comprises a hemispherical dome 8 having air inlets 11 through which air is projected towards the burner nozzle 13, the dome being enclosed by a shroud 9 having air metering holes 10. The portion forming the cooling and insulating air inlet louvre passages may be formed as a separate ring 21 welded to the downstream end of the flame tube section as shown in Figs. 1 and 3, or the downstream end of the flame tube section itself may be suitably formed by a rolling operation. The invention is applicable to combustion chambers having either the tubular or annular type of flame tube. Proportions for the various dimensions are given.

C. engine fuel injector has a fuel duct 27, Fig. 1a leading to a discharge valve 14, 15 and an atomizer 7, the discharge valve opening at a predetermined fuel pressure, and a spill duct 31, Fig. 2 controlled by a spill valve having a resiliently-biased valve member 25, the spill valve closing the entry to the spill duct when the fuel pressure rises above a predetermined value less than the opening pressure of the discharge valve. Fuel is supplied to the port 36 Fig. 1b from a separate metering pump connected through a priming pump which maintains a pressure in the injection valve when the pump is set for zero delivery so that fuel flows through the central duct 35, 33, 27 through a bore (31), Fig. 2 (not shown) and the inside of lining 6 to an outlet duct 45. During the fuel metering pump delivery stroke the increased pressure on valve slide 25 moves the latter to close bore 31 and fuel flows via duct 30 along flats on check valve 23 via bores 19, 20 and 21 into chamber 22. Increasing pressure in chamber 22 lifts valve spindle 13 from its seat 15 to allow injection via nozzle apertures 8. Cooling oil may be circulated through bores 53, 52, chamber 51 and return bores (not shown). Axial pressure is exerted on the pressure head 34 by springs 41. Casing 2 may secured to the cylinder cover 3 by low-temperature shrinking before insertion.

Abstract: 670,372. Watch bracelets. FOSTER, J. May 11, 1950 [Sept. 6, 1949], No. 23123/49. Class 43. A watch bracelet comprises a wristengaging clip 1 provided with an arcuate watch-engaging strip 2 slidable between the clip and a retaining member 3, which is secured to the clip by e.g. rivets 4 passing through a slot 5 in the strip 2, and which is spaced from the clip 1 by a distance piece 6 located in the slot 5 in the strip 2 to guide the latter. Preferably two such strips 2 are employed. The slots 5 in the strips 2 are covered by the arcuate retaining members 3. The pieces 6, the ends of which limit sliding of the strips 2, are thicker than the adjacent parts of the strips 2, so that they take the thrust when the rivets are being set. The strips 2 are held frictionally in their adjusted positions by pre-stressing them to press on the retaining members 3 or vice versa. To facilitate bending the hooked watch-engaging ends 7 of the strips 2 into eyes they are longitudinally slitted to form separate teeth; the latter may be pressed towards each other or spread apart to suit different lengths of watch bars 8. The part of the clip 2 lying beneath the watch may be padded. The pieces 6 may be separate members or may be either integral with, or previously attached to, either the clip 1 or the retaining members 3.
