Abstract: 379,473. Coal-cutting machines. BUTTERWORTH, L., Brampton Terrace, Sand Hills, Gt. Houghton, near Barnsley. July 20, 1931, No. 20663. [Class 124.] In a rotary percussive coal-cutting machine, a tool-carrying shaft 1 is caused to reciprocate upon a fluted driving-shaft 5, which is coupled directly to an electromotor or compressed-air turbine, by means of an undulating piston head 3 formed upon a piston-like enlargement 2 of the shaft 1 and adapted to co-operate with fixed undulating collars 6, 7 adjustable for wear by bolts 14, 17. A fluted nut 4 is screwed into the piston 2 to engage the fluted shaft 5, and friction discs 9, 12 are provided at suitable intervals round the faces of the collars 6, 7. The apparatus together with its motor is fed by means of a hand-operated feed screw 18 inside a framing 20 supported by ball-bearings on cross members (not shown) between uprights 23 so as to be readily swung laterally by means of a handle 25.

IPC: B24B9/04
Filed: 1927-08-05
Abstract: 300,185. Marshall, L. C. Aug. 5, 1927. Piston packing. - Piston-rings for use in internal-combustion engines having cast iron cylinders are made by bending a hard steel wire to circular or elliptical form,' preferably in a. coiling machine, cutting of a single turn to leave the required gap. The wire is formed of 0.5 to 0.75 per cent carbon steel or a steel or similar hardness and may be slightly trapezoidal in section, Fig. 2, becoming rectangular after bending. The rings are flattened in a press and heated to remove helical set while clamped on a mandrel 23, Fig. 16, by means of a sleeve 24. A bar 25 passed through the gaps in the rings. Oblique joints may be formed by means of a grinding wheel or milling cutter 27, Fig. 17, or overlap joints may be provided. Burrs are removed by grinding, the sides of the ring are ground, and the rings are mounted on a mandrel and the peripheries ground.

Abstract: 830,729. Valves. SULZER FRERES S.A. June 27, 1958, No. 20730/58. Class 135. A fluid - operated 3 - way shut-off valve for a line containing a medium at a low temperature comprises a closure member 5 attached by a spindle 4 to the operating assembly, the whole assembly being guided without friction in the valve housing by at least one guide spring 21 in the form of at least one spiral wound in a single plane and held fast at its periphery to the housing and to the valve spindle at its centre and each winding being thin relative to the width. The operating assembly comprises a bell-shaped part 9 attached to the valve spindle and a sleeve part 14 attached to the housing between which a compression spring 15 bears to urge the valve member toward the valve seating 7, and a bellows 12 connected between the bell-shaped part 9 and the housing to form two chambers 27, 28, a further bellows 18 sealing between the valve stem and the housing. Pressure fluid which may be derived from the controlled fluid can be supplied to either of the chambers through ports 25, 26 to control the position of the closure member such as from a reversing relay valve under the control of a further valve. To prevent the cold-controlled fluid interfering with the actuation of the valve an annular evacuated chamber 30 may be provided around the valve spindle. In a modification the direction of action of the loading spring is altered and in a further modification one of the ways is blankedoff to make a 2-way valve.

Abstract: 261,115. Electrical Improvements, Ltd., and Grant, L. C. Aug. 19, 1925. Telephone systems; non-contact-making relays. -An electric vibrator comprises in combination a vibrating member such as a reed or diaphragm, and one or more (and preferably at least two) exciting coils so mounted that they can be used to excite the member at points adjacent to natural nodes thereof, whereby the member will be caused to vibrate with an amplitude above a predetermined minimum only when the frequency of the controlling currents passing through the coils corresponds to the fundamental natural frequency of the member. In its simplest form, Fig. 1, the vibratory member is a rod A adjustably fixed at one end in a bracket and exciting coils B, B<1> carrying controlling currents are fixed adjacent the natural nodes of the rod, the number of coils and their positions depending on the, harmonics to be suppressed and the second harmonic of the fundamental natural frequency of the rod being illustrated. The rod will vibrate with controlling currents of a frequency substantially equal to that of the rod and will not respond appreciably to other frequencies. The rod may vibrate to vary the impedance of, and operate, a trip circuit, being provided for these purposes with either the core of a choke coil in the trip circuit, or with a piece of magnetic material moving in the air gap of a core which is linked with a coil in the trip circuit, a polarizing winding being provided on the core if used with direct current circuits.

Filed: 1949-08-10
Abstract: 674,125. Tipping vehicles. BROMILOW & EDWARDS, Ltd., and KINNAIRD, J. A. Aug. 10, 1950 [Aug. 10, 1949], No. 20805/49. Class 108(i) A tipping vehicle body pivot mounting comprises a transverse structure 8, 9, projecting laterally beyond and supported by the chassis frame members 5, 10, and carrying hinge attachments 15 each formed with a sole plate 16 for securement to the steel body 1 at or near the two side edges. The transverse structure includes a pair of parallel channel, rectangular, or I-section bars 8, and a round rod or tubular hinge member 12 supported between the sections 8 by bridge plates 13, the ends of the member 12 forming body pivots 12A. The plates 13 are generally rectangular brackets peripherally flanged for reinforcement, and each is formed with an apertured eccentric boss in the bore of which the rod 12 is carried. Two pairs of lips 18 project from the edges of the brackets, the uppermost take the load while the lower pair are clear of the sections as shown. The bracket,s 13 may be turned through 180 degrees to permit the hinge rod to be mounted in either of two positions which differ both in height and in longitudinal position along the members 5, or if it is desired to vary the height independently of its longitudinal position, then the plates may be inverted by rotation around their longitudinal axes. The plates may however be made square. The load on the hinge may be taken by resting the bridge plates on support lips from the sections 8. In cases where integral body pivot mountings are already provided, the sections may straddle such mountings and the transverse member 12 be additionally supported therein. The hinge attachments 15 rotate on fixed pivots 12A, but they may alternatively be fixed to the pivots and the hinge rod 12 be rotatably mounted in the bridge plates.

A triggerable vacuum discharge device as described in Specification 1,063,947, in which the metal 19 of the gapped metal/ceramic trigger assembly is a rare earth which evolves and absorbs active gas, e.g. hydrogen, under vacuum conditions within a high temperature range (e.g. 500-700‹ C.), is provided with an additional active gas storage reservoir 25 comprising a metal, e.g. Ti, which evolves and absorbs active gas within a lower temperature range (e.g. 200-300‹ C.). This enables a second bake-out step normally necessary when manufacturing such devices to be omitted. The reservoir 25 consists of Ti powder 29 pressed into an annular recess formed by three outgassed stainless steel rings 26, 27, and 28 mounted between the anode 7 and shield 17.
