[Also in Division F2] A method of expanding a tube 9 inserted in the bore of a plate 10 to the plate, comprises inserting a first ring of elastic material 11 between the tube and plate temporarily positioning an expander ring of elastic material 16 within the tube opposite to the plate and applying thereto an axial compressive stress so as to produce a permanent radial deformation of the tube against the plate and the imprisoning of the first elastic ring between the tube and plate. The expander ring comprises, for example, three rubber rings 16 separated from each other by steel disc 17 mounted on a headed plunger 7<SP>1</SP> which is retracted by hydraulic means relative to a bush 8 to compress the rings and expand the tube, Fig. 12, to form an annular bulge and a flared mouth and trap the ring 11 therebetween. A ceramic tube 12 may be attached to a plate by using a shouldered adaptor 14 which is similarly expanded into contact with the plate, Fig. 14. In another example a metal ring 31 is permanently expanded to retain a thin walled tube 23 in the plate 24, Fig. 15. The plunger and bush assembly may be arranged in and be actuated by a hydro-pneumatic circuit assembly, Fig. 10 (not shown). The bush member may be arranged to move relatively to the plunger means, Fig. 16 (not shown).

Filed: 1927-08-26
Abstract: 277,315. British Thomson-Houston Co., Ltd., (Assignees of Warner, D. F.). Sept. 13, 1926, [Convention date]. Fluid relays.-The admission valve 6 of an elastic fluid turbine is controlled by a governor B driven by the turbine shaft which also drives an oil pump 21 supplying pressure oil through a main pipe 24 to the underside of a spring pressed piston 13 operating the valve 6. Oil in the pipe 24 is kept, at a constant pressure by the setting of a relief valve 25 but the pipe 24 has a main branch 28, and a bye-pass 29 opened by the governor B to vary the pressure in the pipe 28 and so alter the admission valve opening. The bye-pass 29 can supply oil to a sleeve 32 the ports of which are uncovered by downward movement of the pilot valve 36 by the governor and are further uncovered by raising the sleeve itself by a lever 34 connected to a bellows 40 supplied with pressure oil from the flexible pipe 47 to balance the thrust of spring 49. A follow up is provided by connecting the bellows casing to the piston rod 12 so that when it moves up to open the throttle valve 6 it raises the left hand end of lever 34 and it raises the sleeve 32 to damp down the oil bye-pass effect. In a modification the bellows 40 may be replaced by a spring pressure piston. Specifications 173,086; 229,321, [Class 135, Valves, &c.]; and 229,325 are referred to.

Abstract: 506,057. Confectionery. PALIK, F. Aug. 18, 1937, No. 22652. Void. Convention date, Aug. 18, 1936. [Class 28 (i)] In the production of porous chocolate, salts which decompose under normal pressure and at a temperature of from 70 to 90‹ C. are incorporated therein. Substances mentioned are ammonia carbonate, normal alkaline carbonates, carbonates of earth alkalies and rare earths, carbonates of calcium, sodium, magnesium, lithium, in combination with a number of chlorides, e.g. chloride of aluminium, magnesium, calcium or bismuth, which react with the water of crystallization of the crystalline carbonates and form an acidic combination with the carbonate which evolves carbondioxide. Substances such as gluten, gliadine, wheat or corn flour are added to form a strong structure of the porous product. Lecithin also, may be added. The reaction is effected either at normal temperature in a vacuum, or at normal pressure with an increased temperature, i.e., about 72‹ C. When the process is effected under vacuum, it is necessary, after breaking the vacuum, to heat the substance so that the structure is strengthened, or, alternatively, the substance is allowed to solidify in the vacuum.

Abstract: 480,527. Weighing-apparatus. BAAGOE, A. J. Aug. 19, 1936, No. 22872. Convention date, Aug. 30, 1935. [Class 143] An automatic or semi-automatic weighing- apparatus of the kind having a movable member set in accordance with the weighing mechanism, and feelers co-operating with the movable member for adjustment of digit determining members (for example, printing wheels) is characterized in that the movable member is provided with a system of holes divided into groups according to units, tens, hundreds, &c. and the feelers each consist of a system of rigidly interconnected needles which control the extent of movement of the feelers when advanced into the holes. As shown in the Figure, a dial 10 rotated by the weighing mechanism relative to a stationary weightindicating pointer 12 is perforated with a system of holes arranged in three concentric groups corresponding to the hundreds, tens and units denominations. When the dial has come to rest, auxiliary power displaces a stop-bar 19 so as to allow spring-pressed feelers 17, each comprising nine needles, to move into contact with the dial 10. Some of the needles enter the holes in the dial, the extent of the movement being controlled by the number of holes presented to the needles. Racks 18 on the feelers set indicating and/or printing discs 22. An extra needle 23 on the units feeler justifies the dial. When the weighing range of the machine is increased by the addition to the mechanism of counterbalancing weights, the handle or other means for effecting the addition is connected to extra type wheels or digit-setting devices for higher denominations. The rackbars 18 may be connected to the setting mechanism for one factor of a multiplying machine, the other factor, viz. the unit-price factor, being set by the operator. The weighing-apparatus may then deliver a ticket printed with the weight, price and monetary value of the goods.
