Abstract: 778,731. Opening textile fibres. T. M. M. (RESEARCH), Ltd. Dec. 30, 1955 [Nov. 17, 1954], No. 33280/54. Class 120 (1). Apparatus for opening fibrous material comprises a conveyer upon which the material is spread, a co-operating pair of feed elements forwarding the material in the form of a fleece at a controlled rate, a dual spiked lattice conveyer system driven so that adjacent courses of the lattices travel in the same direction at different speeds which effect a " combing and opening action on the material advanced therebetween, and means receiving the opened material at the common discharge point of the lattices. In the operation of the apparatus shown in Fig. 1, the material spread, by means such as the output elements of a bale-breaker, upon a conveyer 10 is deposited on pedals 13, compacted by a roller 11, and pressed into the nip of a roller 12, whence it is presented as a fleece to the spikes of a lattice 14 which detach material from the fringe thereof and convey it upwardly in separated tufts between the lattice 14 and a lattice 18 from the top of which it is delivered to a stripper 21 by which the opened material is impelled into and removed by a pneumatic duct. The rollers 15, 16, and 19, 20, on which the lattices run are mounted in slidable bearings 24 which enable the space B to be adjusted e.g. to converge the lattice runs. The respective speeds of the lattices 14 and 18 may be 500 and 10 feet per minute and on the latter the lags on which the spikes are mounted and individual spikes on each lag may be more closely set : in a modification (not shown)) the tips of the lattice spikes may be staggered and overlapping. As shown in Fig. 2, the lattices 14 and 18 may be driven by a motor 29 through a belt 30 and through a variable-gear unit 31 and reduction gear 32, 33. The roller-and-pedal 12, 13, may be replaced by a pair of wire-clothed rollers, Fig. 3 (not shown). The feed elements may be arranged to deliver the material directly into the space between the lattices at a common intake point. Specifications 735,172 and 735,173 are referred to.

Drilling-machines, particularly radial drills, are arranged so that the engagement of the power feed automatically locks the drill-positioning adjustments. When the lever a<2>, Fig, 1, is rocked to expand a friction ring F in the boss of the worm-wheel bv means of the wedges a<4>, a<5> an adjustable link a<1> rocks a shaft B that locks the arm to the column as described in Specification 137,118 and by means of screw gears a, C rotates a screw c<1> to force a wedge c<2> between a, part of the saddle and. the radial arm. In a modification, the pilot wheel for the hand-feed is mounted on a sleeve concentric with the shaft that carries the pinion for traversing the saddle on the arm. Power feed is obtained from a worm-wheel splined on the sleeve to move into engagement with the driving arm. The sliding is effected by a lever linked to the shaft Band to a screw that actuates a lamp engaging one of the slideways on the radial arm. In a further modification, the concentric arrangement of feed and traversing shafts is retained, and the pilot wheel for the hand feed acts through a spring- pressed ball f<9>, Fig. 4, that yields when the drill meets the work. A quick pitch screw f<6> then slides a yoke a<6> to operate the wedge a<4> of the friction clutch, at the same time rocking the shaft B and locking the saddle &c. as in the first modification.

Title: Improvements in vehicle power units
IPC: F16H61/47
Filed: 1964-08-17
Abstract: 1,046,339. Hydrostatic transmissions. ROBERT BOSCH G.m.b.H. Aug. 17, 1964 [Aug. 16, 1963], No. 33474/64. Heading F2D. An hydrostatic transmission 5, 6 for a vehicle drive is associated with a forward and reverse driving lever 11 which may be coupled alternatively to a torque-responsive control 8 or to a speed-responsive control 9. In the arrangement shown the transmission includes swashplate pump and motor units 5, 6, the pump being driven by the shaft of an engine 1 with fuel pump 2 and regulator 3. The inclination of the pump swash plate 19 is controlled by a servo valve 7 coupled to a link 49 loaded by pistons 50, 51 subjected to the pressures in the hydraulic circuit lines 14, 15. The driving lever 11 is mounted on a shaft 54 which is axially movable to engage clutch elements 55, 57 which render the speed control 9 effective, or in the opposite direction to engage clutch elements 56, 58 rendering torque control 8 effective. The speed control 9 comprises a throttle slide valve member 102 operating in conjunction with a regulating pump 10; while the torque control 8 comprises a piston 81 in a cylinder 82 with an associated amplifier piston 69 and cylinder 70. The cylinder 70 has a toothed rack 83 engaged by a pinion 84 on a shaft 85 carrying a cam 92 coupled to the engine regulator 3 by a spring piston and cylinder unit 93, 96. The shaft 85 also carries a toothed sector 86 meshing with a rack 88 on a cylinder 46 housing a rod 36 coupled to the servo control valve 7 and loaded by a series of three springs 43, 44, 45 designed to have a substantially hyperbolic characteristic. Forward and reverse pressure regulating valves 119, 120 are fitted between the control units 8, 9. Main and auxiliary liquid supply pumps 134, 168 are also provided. Operation.-In the neutral position shown the clutch elements 55, 57 and 56, 58 are disengaged and the hydraulic circuit 14, 15 is short circuited by a valve 154 associated with the driving lever 11. (a) Torque-dependent regulation.-Lever 11 is moved axially to engage clutch elements 56, 58 and rotated for forward travel to move a control rod 67 and the amplifier cylinder 70 to the left, the consequent rotation of shaft 85 and sector 86 operating the cylinder 46 and servo valve 7 to tilt the swash plate 19 so that the pump 5 delivers to the motor 6. The arrangement of the springs 43, 44, 45 is such that the pump delivery pressure is inversely proportional to its output so that at constant vehicle speed the engine output is constant. (b) Speed-dependent regulation.-Lever 11 is moved axially to engage clutch elements 55, 57 and rotated to move the throttle valve member 102 to the left. The main pump 134 is initially exhausted through lines 137, 141, 130, but liquid from the auxiliary pump 168 moves amplifier piston 69 to the left to initiate operation of the pump servo control valve 7 through shaft 85, sector 86 and spring cylinder 46.

Title: Logic circuitry
IPC: H03K19/082
Filed: 1975-08-13
Abstract: 1518123 Logic gate HONEYWELL Inc 13 Aug 1975 [13 Aug 1974] 33691/75 Heading H3T A NOR gate circuit comprises a bipolar transistor having an emitter connected via a resistor to one side of a voltage source, effectively a plurality of bases to which inputs are applied and a collector connected through a load to the other side of the voltage source. Schottky diodes can be connected between the bases and the collector and the emitters may be plural in number, corresponding to the bases, connected in common. The emitter resistor is said to reduce currenthogging. The gate can operate with a lower voltage supply than TTL and ECL and is said to be faster. If desired for simplicity in resolving logic functions, the NOR gate can be used with an AND gate, Fig. 3, substantially as shown where emitter 31 is internally connected to the base. The logic functions NOR, AND apply when a high signal is taken as 1, or true. In the AND gate when the emitters are high the transistor is "of", but actually is in the inverse mode and the output 35 receives current from the base resistor 34 and the basecollector junction. The emitter thus has the loading effect of a collector and increases the fan-out if used as a load for the NOR gate (Fig. 5 not shown).

Title: Improvements in or relating to gas analysers
IPC: G01N7/04
Filed: 1938-11-22
Abstract: 509,288. Gas analysis. ECKARDT AKT.-GES., J. C. Nov. 22, 1938, No. 33996. Convention date, Nov. 25, 1937. [Class 1 (i)] A gas analyser comprises an absorption vessel and an adjustable quantity regulator, which, having no gas escape outlet, operates without loss of gas, in conjunction with similar restrictions in the inlet and discharge passages and a measuring device connected to the discharge passage and responding to the flow of unabsorbed gas. Gas enters a conduit Z and a comparatively small proportion is tapped off via the constriction V and valve V<1>, the main body of gas flowing off through the conduit Z<1>. After passing through the valve, the gas passes into the space K<1> bounded on one side by the diaphragm M. Thence it flows via the constriction B<1> to the absorption chamber A, then through the constriction B<2> and out of the apparatus. The space K<2> behind the diaphragm is connected to the passage between the first constriction and the absorption chamber. The diaphragm is loaded by a spring F whose force can be adjusted by means of a screw S, the valve being also connected to the diaphragm. The difference of pressure occasioned by the constriction B<1> affects the diaphragm and thus the valve, the latter tending to be closed when the difference rises due to an increased flow of gas, thus ensuring a constant flow of gas. This regulator may be replaced by a dipping bell differential pressure regulator. The constrictions are preferably capillaries of about 0.5 mm. bore and 40 mm. length, but may be replaced by other damming apertures, venturi tubes or by nozzles directed towards or away from the gas flow. The pressure gauge D connected before the second constriction may be a precision pressure gauge or if several of such apparatuses be connected in series for selective absorption of various gases it may in each case be replaced by a differential pressure gauge. Instead of or in addition thereto, a recorder or i impulse transmitter may be used. The zero point correction of the gauge may be effected by adjusting the screw S. The volume of the passages traversed by the gases is kept comparatively small in relation to the volume of absorptive liquid which should preferably be about 5 to 10 litres.

[Class 38 (v)] An overload cut-out, particularly of the screw-plug type, comprises a movable bridging- contact 2 carried on a member 9 which is provided with a surface 8 engageable by a ring- shaped armature or coil 7 to hold the contacts closed. The armature is arranged eccentrically of the axis of the release coil 14 and is mounted on pins 10 on bimetal elements 12, 13 secured to a carrier 22. An iron member 6 forming part of the magnetic circuit, serves as a guide for the spring-controlled operating button 18 and for a member 16, to which is pivoted a release member 15, a part 20 of a slot in which normally engages a pin 19 on the member 9. The cutout is closed by pressing 18 so that parts 16, 15, 9 move together until the armature 7 engages the surface 8. With a sufficiently-heavy overload, 7 is moved until its axis is concentric with that of coil 14, so allowing the spring 3 to open the cut-out, and a similar release occurs by means of the elements 12, 13 on small, sustained overloads. If an attempt is made to hold the cut-out closed on heavy overloads, the armature 7 strikes the nose 21 and brings the long part of the slot in 15 level with pin 19, so permitting instant opening. Release of 18 permits re-engagement between 19, 20. The opening force may be supplied by the magnet coil, instead of by the spring 3, the member 9 being then of magnetic material. Magnetic blow-outs.-The magnet frames 5 which support the core 4 and member 6, are extended upwards, Fig. 1, to provide a blow-out field.
