Abstract: 713,966. Gauging alignment of connecting- rods. JERRAM; W. A. Sept. 30, 1952 [Nov. 2, 1951], No. 25695/51. Class 106 (2) A gauge for testing alignment of connecting- rods also comprises a clamping means so that adjustments to the alignment of a connecting rod may be made by applying a bending force without straining the bearing or mandrel on which it is mounted. A mandrel c is screwed into a base a and is internally threaded to receive a screwed rod f the point k of which expands a set of three members, two, of which, hand i are shown in Fig. 1 of the drawings. A tommy bar g is fitted to the screwed rod f to make an adjustable mandrel the effective diameter of which may be adjusted within limits to accommodate different sizes of connecting rods, which are then clamped rigidly between members x. A pointer t is adjustably held on a rod 2 and is slidable in a slot u, Fig. 2, in the web b. In use the connecting rod to be tested is mounted on the adjustable mandrel between the members x x and then clamped in position. The pointer t is adjusted to the centre line of the rod at the big end bearing, and the pointer and rod z are then adjusted to the top of the connecting rod by means of the slot u and the pointer indicates whether the top end of the connecting rod is in alignment with the big end bearing. According to the characteristic feature of the invention adjustable screw clamps d and w are provided on the adjustable mandrel to hold the big end securely while adjustments are made to correct any misalignment in the connecting rod. Fig. 3 shows a further clamp 1 which is adjusted on a gudgeon pin 2 fitted in the little end of the connecting rod 3 and secured by clamps 6, 7. Rotatably mounted in the clamp 1 is a rod 9 having a knurled handle 13 and a pair of pins 11, 12, mounted on a cross-piece 10. In use the clamp is fixed to the connecting rod as shown and the rod 9 is rotated while the distance of the pins 11, 12 from the vertical web b of the gauge is noted, any misalignment being shown by variations in distance between the tips of the pins 11, 12, and the web b.

Abstract: 1,260,489. Burners. GAS COUNCIL. 29 May, 1969 [30 May, 1968], No. 25918/68. Heading F4T. A tunnel burner comprises a combustion chamber 13 having an open exit at its down stream end and an upstream end wall 10 from which projects a protrusion 17, an air duct 11 supplying a series of elongated air orifices 15 opening into the combustion chamber, and a fuel duct 12 supplying a series of elongated fuel orifices 18 opening into the combustion chamber, the air orifices 15 being arranged with their respective axes substantially parallel to the axis of the burner and each of the fuel orifices 18 being so arranged in relation to a plane containing the axes of the two nearest air orifices that the axis of the fuel orifice passes through that plane substantially at right angles thereto and between the axes of those two nearest air orifices. As shown, the combustion chamber or tunnel 13 is formed axially in a cylindrical block 14 of refractory material, and the downstream face of the protrusion 17 is provided with two small pilot fuel orifices 20 located one to each side of a spark plug electrode ignition device 19. In a further embodiment (Figs. 3, 4 and 5, not shown) the wall of the fuel duct 12 is thicker and has formed in its outer surface a number of circumferentially equispaced longitudinal grooves (21) which, together with the radially inner edge of the central aperture in the wall 10, define the air orifices. Fig. 6 shows a complete view of this second embodiment described, which is a tunnel burner of the recuperative type, in which fuel is supplied through an inlet pipe 42, air is supplied through an inlet pipe 53, and products of combusion flow along annular passage 54 to flue outlet pipe 36, heating the air passing along air duct 11.

Abstract: 635,854. Mine-props. PARRY, E. Sept. 25, 1947, No. 26001. [Class 20 (ii)] A mine prop comprises two lengths 1, la pivotally connected at 4 to form with their male and female members 2, 2a a rigid prop when in the working position, being releasably locked together by a main catch 9 pivoted to the female member and engaging the male member and releasably locked by an auxiliary catch 10 pivoted thereto and engaging the female member. A female portion 2c in the member 2a receives a male portion 2b on the member 2 which is slotted to receive a portion of a catch lever 9 hooked to engage a transverse pin 6 in the slot, the catch lever being pivoted at 9a to lugs 8 on the member 2a so that it may be pulled out of engagement, by a chain 12, to an extent limited by'a stop 9c: A second catch 10 is pivoted to the catch 9 and hooked to engage an edge of the slot in the member 2 and is provided also with a hook 10a over which is looped a spare link 12a of the chain whereby the pull first disengages the catch 10 and then the lever 9. Further locking means consists of a pin passing through a hole in the catch lever 9 and lying across the catch 10 so that it cannot rise until the pin is withdrawn. This pin I may be secured against loss by a chain 11b. The edges of the portion 2c and of the member 2 which are in contact are curved to allow the portions of the prop to swing apart, and these curves may be such that there is a slight wedging action when the prop is in the working position. The pivot 4 may be off-set from the main axis of the prop so as to increase the effort required to collapse it. Downward projecting walls 2i form a shield for the curved faces.

Title: Epoxy resin adhesive compositions
IPC: C09J163/00
Filed: 1960-07-26
Abstract: A pulverulent composition of a polyepoxide, a salt of a polyamine, and a strong base may be prepared by absorbing a liquid polyepoxide and a salt of a polyamine on a finely divided filler, and mixing the two products together with a strong base e.g. sodium or potassium hydroxide. Addition of a solvent, e.g. water or ethylalcohol for the amine salt and the base activates the composition which may be used as an adhesive, particularly for tiles. A suitable filler is a mixture of sand with a silica aerogel.  In Examples I and VI crystals of diethylene triamine hydrochloride and powdered sodium hydroxide were mixed with sand and silica aerogel on which a liquid polyepoxide of formula: <FORM:0949317/C3/1> had been absorbed to yield stable free-flowing powders, which mixed with water could be trowelled on to a concrete floor as an adhesive bed for ceramic tiles. II and III are similar but use an adsorbate of N-octadicyl trimethylene diamine hydrochloride on silica aerogel. IV the acetate of N-octadecyl trimethylene diamine was cured. V the phosphate of the same diamine was used. VII is similar to II and III but uses a polyepoxide of formula: <FORM:0949317/C3/2> VIII is similar to II and III but uses Wollastonite in place of sand, and includes TiO2 to give a white finish.  Other examples illustrate the use of the hydrochlorides of bases available commercially under the Trade Name "Duomeen". Specification 718,850 is referred to.

Abstract: 445,992. Controlling aircraft. JACQUEMIN, A. F., Saucourt, near Doulaincourt, Haute Marne, France. Sept. 19, 1935, No. 26034. Convention date, Sept. 20, 1934. [Class 4] An aircraft with transversely hinged wings is provided with two distinct controls, an elevator control and a manual control for the wings which is provided with an elastic return tending to return the wings into the position of normal flight. A fuselage 3 carries wings 1, 2, turnable about shafts 1<1>, 2<1>, respectively, and an elevator 9. Elevator 9 is actuated by fore-and-aft movement of control column 4, lateral movement of which produces, through the transmission shown, rotation of a shaft 24 carrying a two-armed lever 25 of which the ends are linked to wings 1, 2 respectively. Lateral movement of column 4 thus effects differential setting of the wings. Shaft 24 is universally jointed at the end remote from lever 25 and means operated by hand lever 35 are provided for rocking the lever carrying end of shaft 24 in a vertical plane for producing equal rotation of wings 1, 2 about their pivots. Lever 35 is spring biassed to a position corresponding to a positive incidence of the wings by a spring 43. Guides 36 prevent lateral movement of shaft 24.
