Abstract: 489,659. Knitting-machines. BLACKBURN & SONS, Ltd., G., and TOWERS, E. J. Feb. 1, 1937, No. 2845. [Class 74 (ii)] Patterning slides G carried one above the other in a frame which revolves with the cam box D are moved outwards, by pivoted links P controlled by a pattern drum Q, to select butted needle jacks B and are retained in the outer position by spring detents K. The detents are tripped and return to the inner position just before they reach another or the same stationary pattern drum Q, where a fresh selection is made. The detents are tripped by bars N, N<1> which are rocked via linkwork O, O<1>, O<2> so as to engage one arm K<1> of the detent and pivot the other arm away from a shoulder G<2> on the slide G, the slide being then retracted by the spring M. Unselected jacks, i.e. jacks not pushed in beyond the range of a cam C, are raised by the cam C. The needle cylinder A tapers from bottom to top, so that the tricks are deeper in the lower part than in the upper part, thus accommodating jacks of increased strength.

Abstract: 142,928. Vickers, Ltd., and McKechnie, Sir J. Feb. 13, 1919. Hatches and hatchways. - A radial vane or piston b arranged on a shaft a within a cylinder c and adapted to be operated by liquid under pressure admitted alternately through ports l, m to the opposite faces of the piston, one or more valves and ports such as p, o, n being provided so that the piston may be cushioned towards the end of its movement in one or both directions. In the movement of the piston towards the abutment f of the cylinder, the non-return valve member is forced back on to its seating n<1> so that the pressure fluid may only escape from behind the piston through a restricted passage q. In operating the piston in the reverse direction, the valve is moved as to allow the pressure fluid to pass behind the piston through the ports n, o, while to cushion the piston during this movement an arrangement with a similar non-return valve member may be provided. This arrangement of oscillating vane piston may be used for closing an opening in the deck of a vessel and is shown in connexion with the boiler installation for vessels of the submarine type in Fig. 3. The part, y of the funnel extending above the deck is connected to an oscillating shaft a, and a cover w is similarly actuated, whereby the boiler uptahe may be rendered water-tight when it is desired to submerge.

A film evaporator or gas/liquid reactor comprises a frusto-conical jacket 1 having a vertical axis and tapering downwards, a liquidinlet 7 at the upper end and a liquid-outlet 8 at the lower end, and rotary blades 2 which distribute the liquid in the form of a film on the inner wall of the jacket, the arrangement being such that the thickness of the film is non-uniform along the inner wall. As shown, the gap 21 between the blades edges and the inner wall increases in width towards the outlet, so that the liquid remains in the lower region of the apparatus for a longer period. In an alternative construction, the gap decreases in width towards the outlet. The inner wall of the conical jacket and/or the blades edges may be provided with groove-like recesses. In the case of a film evaporator, vapours flow out through pipe 9 which may be connected to a condenser and a vacuum pump. In the case of a gas/liquid reactor, a gaseous reactant is introduced through pipe 9. The jacket 1 may be externally heated or cooled. It is stated that the blades may be replaced by a rotary solid cone or a rotary perforated hollow cone.

Abstract: 1424865 Tape recorders; detecting imminent end of tape. PIONEER ELECTRONIC CORP 25 Jan 1973 [26 Jan 1972] 3956/73 Heading G5R [Also in Division H3] An electrical device for detecting the imminent end of a tape in a tape recorder senses the increasing rotational speed of the tape supply reel and produces an output when it exceeds a predetermined value. As shown, a switch S is provided on the supply reel shaft 4 and is switched at a rate proportional to the rotational speed. The switch S may include a brush, or may be a magnetically-operated reed switch. When the switch S opens, a capacitor C3 charges towards the Zener voltage of Zener diode ZD2, but is normally prevented from reaching it by a capacitor C2, which, when switch S is next closed and transistor Tr1 is turned off, charges and reaches the Zener voltage of Zener diode ZD1 first, thus turning on transistor Tr2 and discharging capacitor C3. When the switch S is next opened, Tr1 is turned on, C2 is thus discharged and Tr2 turned off, permitting C3 to charge again. At sufficiently high switching rates, capacitor C2 never reaches Zener voltage ZD1, so that Tr2 is always off and C3 is allowed to reach Zeher voltage ZD2, thus turning on transistor Tr3. The load L may be a lamp, or a relay which actuates another tape recorder.

[Class 51 (ii)] The discharge opening 2 of a glass-melting tank is fitted, in addition to the usual vertically sliding gate 3, with an inclined water-cooled register 8 adapted to be lowered into the glass so as to cover completely the renewable discharge lip 4 provided along the lower side of the opening 2. In the form shown in Fig. 1, the register 8 is formed with forked lugs 12 in which are pivoted guide rods 21 slidable in bearings 22, the lower ends of the rods 21 being formed with stops 27, Fig. 4, which maintain the register in the plane X-X but permit a pivotal movement towards the interior of the tank in order that the register may be freed from any adhering cold glass before being raised by the hoisting cable 15. In addition to the fully lowered position 9b, the register may occupy position 9<a> when it is desired merely to cut off the flow of glass, position 9 or 9<d> in which it acts as a cooler for overheated glass and a screen for the upper member 5 of the rolling machine, or position 9<e> in which free access to the roller 5 is provided. Fig. 5 shows a modification in which the register 8 is carried by pivoted arms 29, 30 on each side of the furnace, slotted connections with the lower arms 30 being provided to permit the small inward pivotal movement necessary to free the register.
