[Also in Division E1] An assembly comprises a member 1, for picking up a load and supported between arms 5 by pivots 12 engaging tracks 13 on the sides of the member 1, interengageable cam means 16, 17 being provided on the member 1 and the arms, respectively, whereby when the member 1 is loaded and is lifted by the arms the pivots move relative to the tracks and the member is moved by gravity to a roll-back position. The member 1 may be a bucket, scoop, fork or beetlifter. The arms 5 are adapted to be removably but rigidly attached to arms 7 of loading equipment. The pivots 12 are disposed well forwardly of the centre of gravity of the member 1 when it is loaded, and the upper ends of the tracks 13 have resilient stops 11 for engagement by the pivots 12 when the member 1 is tipped during its discharge. The cam means comprise rollers 16 on the member 1 engageable with cam surfaces 17 formed by cut-outs 18 in the arms, the cut-outs having gaps 19 through which the rollers 16 can pass and which are closed by releasable spring-loaded latches 20 operated by a cable 22 when the member 1 is to be discharged. The rollers 16 are pivotally mounted on the member 1 for movement laterally thereof against spring-loading so that after discharge the member 1 can be lowered on to the ground to re-engage the rollers 16 in the cut-outs 18, the rollers being moved laterally of the member 1 by engagement with chamfered lower edges of the arms. When the member 1 has been raised and has been rolled back the rollers 16 are trapped between the latches 20 and freely swing- ing pivoted latches 40 on the arms.

Abstract: 1290176 Glass-fibre manufacture W H W SCHULLER 18 July 1969 [18 July 1968] 36323/69 Heading C1M In a method of making glass-fibre bodies in which glass filaments are passed to a drum for attenuation to fibres, a coating liquid such as a lubricant is applied to the fibre in two separate applications, one prior to the fibre passing to the drum and the second after leaving the drum. The first application is made using an oiling strip d after which the fibres f are passed to a drum 1 and confined thereto by a rotary air blast S provided in a channel 4 which extends along the entire length of the drum. The fibres are removed from the drum by a stripper 2 and carried by the air blast past a coating roller 7 supplied continuously with liquid from a dripping or spraying device 8 and along a guiding device 6 to the position at which the fibres are consolidated into a fibrous body. In a modification the fibres pass from the drum 1 along a guide 19 and into a " spinning funnel" 11 which comprises two cylindrical sections 13, 12 divided by a circumferential aperture, the section 13 having perforations 14, where the fibres undertake a vortex motion to emerge from an orifice 15 as a sliver FB. The liquid coating is applied by the inner periphery of a rotating ring 17. The ring 17 is provided with bores (22), Fig. 4, not shown, which convey liquid from a reservoir to the inner periphery 18 by virtue of the rotation of the ring. The ring 17 may be replaced by three rotating discs disposed 120 degrees apart around the funnel, one being supplied with liquid from a reservoir and the other two from dripping devices. In further modifications the circumferential wall of the spinning funnel has an axial aperture through which protrudes a member carrying a piece of felt which is supplied with liquid from a reservoir or a tongue carrying a fine wire mesh.

Abstract: 1328241 Control of AC motors NATIONAL RESEARCH DEVELOPMENT CORP 27 April 1971 [5 May 1970] 21653/70 Heading H2J A three-phase squirrel cage induction motor has its supply current modulated by threephase rectangular waveforms whose frequency is preferably an integral submultiple of the supply frequency. Of the side bands so generated, it is shown that one appears in phase at all motor terminals 13-15 thus having no effect on motor operation whereas another, at frequency (1Œ(1/m))fo, the particular sign depending on the sequencing of the modulating waveform with respect to the supply sequence, where fo is the supply frequency, and the integer m the order of the submultiple, can be used to control the motor speed in steps by changing the value of m, and the sequencing. With reference to Figs. 1 and 5, the modulation is effected by changing the phase of each of the lines A-C by 180 degrees, each time its corresponding modulating waveform passes through zero, by switching the supply from, for example A<SP>+</SP> to A- &c. The corresponding waveforms are detailed in Fig. 3 (not shown). The phase changing is accomplished by means of bidirectional thyristors 7-21. For a # connected motor, each end of each winding is brought out to a pair of phase lines via two of a set (1-12) of thyristors, Fig. 2 (not shown). Thyristor control system. Fig. 5.-The zeros of all phase waveforms are detected in detector 21, see also Fig. 6 (not shown), summed in OR- amplifier unit 22, see also Fig. 7 (not shown), and increase the count of preset counter 23 until a predetermined count, defining the modulating frequency fo/m is reached, whence an output pulse to divider 26 causes production of complementary rectangular waves which via logic unit 27, see also Fig. 8 (not shown) provide enabling signals to amplifiers 36-41 at the required frequency and sequence to enable triggering pulses from generator 34 to reach the thyristor gates.

A scraper 44 pushes material from the disc 38 into a funnel 46 leading to conduit 19 at a constant rate, to be entrained by the oxygen supplied to the casing. A pressure relief disc 56 is mounted on the casing cover, and a low temperature fuse 60 in the conduit 18 cuts off the power in the event of a flash back. A temperature sensor 62 in the cooling jacket of the tube 8, a pressure sensor 82 monitoring the gas in the tube and oxygen valve 68 are connected through a control box 50 with a purging nitrogen supply valve 70, a nitrogen pressure sensor 64 and a vent relief valve 74. Melting of the fuse 60, overheating of the lance, or a deviation from the set value of the pressure of the lance closes the oxygen valve 68, opens the nitrogen valve 70 and stops the drive of shaft 34.
