Abstract: 1,118,140. Rolling threads. J. M. PLAGEMANN, [trading as PEE-WEE MASCHINENUND APPARATEBAU WERNER PLAGEMANN]. 7 March, 1967 [8 March, 1966], No. 10600/67. Heading B3M. A thread rolling machine includes two rolls which are mounted in a common plane and rotate in the same direction at different peripheral speeds, one of the rolls being mounted on a carrier which is pivotable to a limited extent about an axis at right angles to the roll axis. Conveniently, three rolls 15, 12 and 16 are provided, the central one being fixed and being rotated at twice the peripheral speed of the outer rolls. The helix angle of the central roll is half that of the outer rolls in order to equalize wear between the three rolls. The carriers are of similar construction, the lefthand one being carried by an axle 6 for limited rotation within a slide 4. The slide is movable against an adjustable stop 8 to determine the spacing between rolls 15 and 12, and includes extensions 35, 36 which carry adjustable stops 27, 28 and springs 31, 32 for determining the degree of oscillation of the roll and its holder. Blanks 43 are gravity fed between the rolls and are delivered in directions 46 and 47.

Void [Abridged as open to inspection under Sect. 91 of the Acts, July 31, 1933]. [Class 38 (iv.] Protective arrangements. -Relates to an arrangement for effecting reactance compensation in a line L, Fig. 2, by coupling to the line a condenser C in which the overload voltage applied to the condenser is limited by the core P of the transformer saturating and consists in means for automatically short-circuiting a winding T on the occurrence in the core of a high saturation due to overload or short circuit so as to avoid undesirable saturation phenomena. Fig. 1 shows the currentvoltage curve of the transformer condenser combination, saturation of the core occurring at the point a. Since the curve has the loop a b c due to the magnetising current cancelling the capacity current instability occurs at a and as soon as the current exceeds the value Ia the voltage jumps to the upper part c e of the curve and it is necessary to reduce the current to the value Ib before saturation disappears. A relay K having an operating coil A energised from a current transformer in the secondary circuit short circuits a winding T through a maintaining coil H when saturation occurs, the maintaining coil holding the relay closed while the overload persists. In a modification for a three-phase line a star-connected secondary is connected to a star connected group of condensers the operating coil of the relay being connected to a transformer in the neutral lead. Specification states that the loop a b c may be removed by applying a resistance load when saturation occurs.

A lever arm D is pivotally connected to a part A by a laminated torsion bar C, the planes of the laminµ of which are approximately parallel with a plane containing the arm D, so that when the latter is loaded, the torsion bar may deflect under both shear and torsion. As shown, the bearing B1 securing one end of the bar C to a vehicle frame, permits axial, and limited bending, movement. The bearing B1 may be replaced by a shackle connection. One of the laminae may be notched or upset to engage the clamp G. The arm D may alternatively be secured to the ends of the bar C, the centre of which is then clamped to the frame. According to the Provisional Specification, the two sections C2, C<SP>3</SP> of the torsion bar may be of unequal length, and may be formed as separate sections, terminating at the clamp G. The laminae may be spaced from one another, to eliminate interleaf friction. Specification 705,846 is referred to in the Provisional Specification.

Abstract: 129,434. Mitchell, J., and A.B.C. Coupler, Ltd. July 9, 1918. Buffers.-In a buffer for railway &c. vehicles, the buffer rod or spindle is made separate from, and adapted to be inserted in, the buffer head from the front, the material of the spindle preferably having a greater tensile strength than that of the buffer head. In the construction of hollow buffer shown, the spindle D is passed through a central opening in the buffer head A and is formed with a conical or cylindrical head I of circular or rectangular cross-section seating in a recess in the buffer head. The spindle is secured to the buffer head either by means of a split spring ring J, or by beading the material of buffer head over the head I of the spindle, or by shrinking the buffer head on to the spindle, or by forcing the spindle by hydraulic pressure through a slightly smaller opening in the buffer head. A washer G shrunk on, or otherwise secured to, the spindle D serves as a front abutment for the usual spring E. Modifications are described in which the buffer head is substantially flat and is distanced from the washer G by a sleeve shrunk on to the spindle; or the sleeve may be replaced by a projection integral with the buffer head, or the sleeve and buffer head may together form a plunger of the solid type.

Polyurethane foam is prepared by reacting a di- or poly-isocyanate, in the presence of a blowing agent, with a polyol, having a hydroxyl number of 200-700 mg. KOH/g., which has been prepared by reacting (I) unsaturated fatty acids or their esters and/or rosin acids with (II) a dienophilic dicarboxylic acid, anhydride or ester, e.g. maleic anhydride, and (III) a polyhydric alcohol, i.e. one containing 3 or more OH groups or containing two hydroxy groups and at least one other group capable of reacting with isocyanate and carboxyl groups. The ratio of (I) : (II) ranges from 16 to 30 : 1 (by weight) and (III) is used in an amount in excess of that required to esterify the reaction product of (I) and (II). Low molecular weight polybasic acids may also be included and polymeric fatty acids may be added when reaction between (I) and (II) is complete. An alkylolamine may be added during or at the end of the reaction forming the polyol. (III), e.g. glycerol, may be used in such an excess that some free alcohol is still present during reaction with the polyisocyanate. A preferred (I) comprises 80-50% by weight of tall oil fatty acids and 20-50% by weight of rosin acids. Conventional catalysts, surfactants and fire-retardants may be present during the polyurethane forming reaction.
