Abstract: 422,015. Drawing-apparatus for bast and long leaf fibres. STONE, M. B., Canton Avenue, Milton, and WILLIAMSON, W. P., Ludlow, both in Massachusetts, U.S.A. Dec. 8, 1933, No. 34663. [Classes 120 (i) and 120 (ii)] A drawing-head for drawing fibres of flax, hemp, jute, ramie, sisal, and manilla comprises pairs of feed and drawing rollers and at least two slip draft devices one of which consists of a pair of rotary elements and another of which situated nearer the feed rollers is connected to one of the said rotary elements so that the pressure of the sliver on it causes the rotary element to be urged towards its fellow. In the drawing- head of a spinning frame three slip-draft devices comprising a rod 6, a channel 7, having a bell-mouthed entrance and slightly curved base, and fluted rollers 8, 8<a>, Figs. 1 and 2, are arranged between the feed rollers 2 and drawing rollers 3. The roller 8 is positively driven and drives the roller 8<a> which is formed of reduced diameter over its central portion and is mounted on an arm 9 pivoted at 10. The rod 6 is disposed adjustably in a slot 12 in an arm or bracket 13 while the channel 7 is mounted by a bracket 14 slotted at 15 on the arm 9 which supports the roller 8<a> so that on the passage of a bunch of long fibres the greater pressure on the channel 7 is transmitted through the arm 9 to the rollers 8, 8<a> thus increasing their retarding action and preventing the passage forward of short fibres. In a drawing-frame four slip-draft devices are interposed between the feed rollers 21, 22 and drawing rollers 23, Fig. 4, and comprise a stationary rod 35, a channel 36 and two pairs of positively driven rollers 37, 37<a> and 38, 38<a>. The channel 36, Fig. 6, comprises a curved base 41 and substantially helical side walls 42 the rod 43 being angularly adjustable to provide passages of varying width. The channel 36 is mounted on the bracket 39 supporting the rollers 37<a> 38<a>. The roller 38<a> is mounted in a loose bearing and bears on the roller 38 by its own weight only. The roller 37<a> is fixed relatively to the bracket 39 and is loaded thereby and by the action of the channel 36. In a modification, the four devices comprise a rod 50, two channels 51, 52 and a pair of rollers 53, 53<a>, Fig. 7. The channels are of V-cross-section Fig. 8, and are mounted respectively on an arm 54 adjustably pivoted on the bracket 55, which carries the roller 53<a> and on an arm 56 which carries the roller 53. If desired the V-groove, Fig. 8, may be widened considerably while the form shown at 57, Fig. 9, may alternatively be adopted. The open sides of the channel members may also be closed by a weighted or spring pressed member. Specification 407,690 is referred to.

Title: Apparatus for Measuring the Velocity of Acoustical Waves
Inventor: PARENTI WILLIAM C
IPC: G01N29/024
Filed: 1966-08-04
Abstract: 1,151,699. Measuring acoustical wave velocities; transistor oscillator circuits. AMERICAN BOSCH ARMA CORP. 4 Aug., 1966, No. 34919/66. Headings H3T and H4D. In a system for measuring the velocity of acoustic waves in a fluid, acoustic pulses are transmitted from a transducer towards a convex reflector spaced a predetermined distance from the transducer in the fluid and echo pulses received at the transducer are used to initiate the transmission, whereby the transmission pulse repetition frequency provides an indication of the velocity. In the embodiment of Fig. 1 for measuring sea-water temperature (derived from the acoustic velocity) as a function of depth, a barium titanate transducer 66 and reflector 91 are mounted in a housing 3 provided with orifices 30 and 32 through which water flows as the housing sinks. A pressure sensor 42 (i.e. a depth indicator) and the transducer 66 are connected to circuitry which provides a composite signal indicating depth and acoustic velocity. This signal is passed, via cable 16, to a buoy 2 to modulate the carrier wave of a telemetry transmitter provided with an antenna 9. Circuitry providing an output signal of frequency proportional to acoustic velocity is illustrated in Fig. 5. Transducer 66 is caused to vibrate at its resonant frequency by a brief (compared to the period of vibration of the transducer) negative pulse occurring when transistor 128 of an astable multivibrator is in its conducting state, thereby launching an acoustic pulse giving rise to an echo pulse which returns to the transducer when transistor 128 is in its non-conducting state (the free-running pulse repetition period of the astable multivibrator in the absence of external switching signals being greater than the echo period of the acoustic pulse). The echo pulse passes (via capacitors 142, 146) to a three-stage amplifier and the amplified pulse is fed back to the collector of transistor 128 to return transistor 128 to its conducting state and thus re-energize the transducer 66. The multivibrator is thus driven by the echo pulses at a frequency dependent on echo time, and hence on acoustic velocity. Details of the mounting of transducer 66 are given. The use of a common go and return path for the acoustic waves propagating between transducer 66 and reflector 91 reduces velocity measurement errors due to motion of the fluid in the direction of propagation. Reference has been directed by the Comptroller to Specification 1,084,056.

IPC: A01B3/421
Filed: 1969-07-11
Abstract: 1,255,538. Reversible plough. ROBERT H. CRAWFORD & SON. 10 July, 1970 [11 July, 1969], No. 35037/69. Heading A1B. The plough beam 7 of a reversible roll-over plough is pivotally supported for movement through 180 degrees on a main frame which has brackets 3, 3' for attachment to a tractor three-point hitch. The rotation is powered by a double-acting ram 30 one end of which is pivoted at 31 to a vertical projection 33 of the main frame. The other end takes the form of a latch-pin 35 which rides in a U-shaped slot 17 at the end of the beam 7. The arms of the slot are directed toward the axis of rotation of the beam so that, to rotate the beam from the right-hand position in Fig. 1, the ram is contracted when the pin 35 is at the bottom of the slot 17. This causes the beam to rise to the solid position of Fig. 1 after which the weight of the beam assists the completion of rotation. The ram is then extended a little to allow the pin 35 to drop to the bottom of the slot once more. The rear-wheel assembly (Fig. 4, not shown) pivots on a vertical axis and is of adjustable height relative to the frame.

As shown, the cell housing 28 defines a second reactant supply chamber 26 behind the cathode 7. The reactant supplied under pressure to - chamber 24 passes through the porous sinter plate 20 and reactant gas bubbles are ejected into the circulating electrolyte in chamber 22 to directly contact the entire reactive surface of the anode 5. In an alternative embodiment, Fig. 3 (not shown), an occulating electrolyte chamber 22 and bubble distributer plate 20 are disposed behind both the anode and cathode, in which event both electrodes are hydrophilic and the need to provide the electrodes and separator of the high bubble pressure type is eliminated. The electrodes 5, 7 may comprise a conductive Ni screen embedded in Pt and P.T.F.E. particles, a porous metal sinter or a carbon disc. The separator 6 may be formed of asbestos or ceramic or polymeric materials and the distributor plate 20 may comprise porous Ni, Cu, Ta or Fe, or it may be formed as a multiple orifice metal or plastics plate. The electrolyte is preferably a 30% aqueous KOH solution, although generally alkali and alkaline earth hydroxides and carbonates and hydrochloric, sulphuric, nitric and phosphoric acids may be employed. The reactants are hydrogen and oxygen, and the fuel cell can operate on unscrubbed air by having a regenerator system with the circulating electrolyte to remove impurities therefrom.
