Abstract: 1,200,031. Lobster pot. J. SALY. 16 April, 1969 [16 Jan., 1968], No. 2315/68. Heading A1A. A section 4 of the conical flange of the mouth of a lobster pot, hinged to the edge of the mouth and biased by a rubber band 5 towards a position where it closes the mouth, is held in the open position by a galvanized steel staple 6 which passes between two parallel members 7 of galvanized steel wire secured to the body of the lobster pot, the staple being locked in position by the insertion of a pin 8 of magnesium wire. Corrosion of the magnesium wire by electrolytic action releases the section 4 after a time dependent on the wire thickness, the separation of the parallel members 7 and the tension in the rubber band 5. Alternatively a galvanized steel pin 8 if used will keep the mouth open.

An insulator 7 having apertures 9 bears against the underside of a discharge tube 3, the flexible leads 5 passing loosely through said apertures. The apertures and the intervening space are filled with a pliable temperatureresistant insulator 10 such as silicone grease. This prevents the leads from being bent at their most brittle point, where they emerge from the glass seal; and the apertures 9 have chamfered ends, so that the leads bend in a smooth arc. The leads may be of different lengths to facilitate threading through the apertures. Several tubes may be mounted on a common insulator, a suitable substance for which is fluorethylene.

Abstract: 158,262. Western Union Telegraph Co., (Assignees of Milnor, J. W.). Jan. 28, 1920, [Convention date]. Artificial lines. - An artificial line for duplex working comprises separated parallel resistance sections 5, 6 connected respectively to the cable and earth and condensers c1, c2, c3, c4 connected between different points along the resistance sections. The resistance steps at the ends 5<a>, 6<a> are greater than thcse at the ends 5, 6, and those in 5<a> greater than in 6<a>. The condensers may be adjusted to different contact points along the resistances by means of flexible connections and adjustable resistances r<1> are preferably inserted in series with some or all of the condensers. It is stated that the lumped resistances and capacity assist in balancing the inductance of the cable, and equations are given for the conditions of correct balance at all frequencies. The effects of a change of electrical characteristics in sections of the cable and of a ' sea earth ' can be corrected by a slight adjustment of the condensers, and leakage may be balanced by adding high resistance leaks at points in the artificial line.

Abstract: 489,418. Feeding capsules &c. HANSEN, A. L. Jan. 26, 1938, No. 2482. [Class 78 (i)] [Also in Group XVII] Apparatus for feeding bottle capsules to a capsuling-machine or cups to a machine for filling them with chocolate, ice-cream, or the like, comprises a magazine for holding the capsules &c. in a telescoped pile and a movable pair of stops disposed at unequal distances from the end of the magazine and each adapted to support the pile and actuated by a common driving means so that they can be moved alternately into and out of the path of the pile and alternately support the lowermost and lowermost but one of the capsules &c. in the pile while the driving means also actuates a tongsshaped catcher which, in accordance with the movements of the stops, is moved towards the stops and opened to grip the rim of the lowermost capsule &c. and closed and moved away from the stops to draw the capsule &c. from the pile and deliver it to the capsuling or filling machine. As shown the stops 4, 5 each comprise a pair of jaws coaxially mounted on shafts 7, 8 carrying respectively arms 14, 9 having rollers engaging cams 16, 11 on a shaft 12 driven from a shaft 13 which carries a cam 24 engaging a roller 23 on a lever 22 pivoted in the frame 1. The lever 22 is connected by a link 21 to an arm on a shaft 19 carrying the arm 18 of the tongs-shaped catcher, the other arm 26 thereof being pivoted to the arm 18 and carrying a rod 29 which passes through the arm 18 and carries a roller 31 resting against a cam 34 on the frame 1. The jaw 26 is influenced by springs 28, 32, the former keeping the jaws closed on the latter tending to open them and, with the pile of telescoped capsules &c. in the magazine supported by the jaws of the stop 4, the shaft 19 is actuated so that the catcher moves towards the stop, a spring- controlled rod 35 being moved by an eccentric 40 driven from the shaft 13 so that its bevelled end 42 is forced against the roller 31 to open the jaws of the catcher which then lie between the jaws of the stop 5. The jaws of the stop 4 are then opened, the pile of capsules moves down until stopped by the stop 5 and the rim of the lowermost capsule passes between the jaws of the catcher which is closed by the upward movement of the rod 35. The stop 4 is then returned to support the rim of the lowermost but one of the capsules, the stop 5 is opened, and the shaft 19 moves the closed catcher to withdraw the lowermost capsule from the pile ; as the catcher is swung back by the shaft 19, the roller 31 is moved by the cam 34 to push the rod 32 forward and open the jaw 26, the released capsule dropping from the catcher into a shoot leading to the capsuling or filling machine.

In a typewriter the key levers 21 are actuated by fluid drive members each including a core 14, Fig. 1, the ends of which support flanges 12 which in conjunction with a recess 16, Fig. 2, in the core and a tape loop 11 passed about the key lever and the core define a fluid pressure chamber 15 into which pressurized fluid is admitted through a conduit 17 to inflate the tape 11 which thereby deflects the key lever 21 downwardly to operate a type action 23. The fluid is admitted to the conduit 17 on depression of a key V which is constituted by a slide valve. In another embodiment (Fig. 4) the core 14 is replaced by an annular ring 34 which defines a hollow chamber 38 having a coaxial pressurized fluid inlet 37, the tape 31 being passed into the chamber through peripherally spaced slots 33. The endless tape 31 which is also passed over the key lever 21 is distended against the inner walls of the chamber 38. In a further embodiment (Fig. 6) the endless tape 42 is passed into the hollow chamber 44 through a single vertically aligned slot 43.

Abstract: 824,279. Hydraulic transmissions; fluidpressure servomotor-control systems. METALLWERK GLOCKERAU G.m.b.H. Jan. 30, 1956 [Feb. 3, 1955], No. 2864/56. Classes 69 (2) and 135. [Also in Group XXX] An hydraulic drive for a hoisting gear comprises a fixed stroke axial piston motor 2 driven by a variable stroke axial piston pump 1. The pump stroke is adjusted by a servomotor 30 which is initially set by a handcontrol lever 4 acting through a spring 51 on a lever 50 connected to a valve 33 of the servomotor, a follow-up piston 31 controlling the pump stroke. For lifting, the pump is set as shown, and a piston 61 bears on the servocontrol lever 50. Piston 61 is subject to the pressure in the high pressure lines 18, 180 of the system and, if the pressure rises above its desired value, it rotates the lever 50, thus raising the valve 33 and causing the piston 31 to reduce the pump stroke to maintain a constant output pressure. In the zero delivery position of the pump a nose 12 on the pump casing actuates a valve 100 to open a line 21 to the delivery of a gear pump 8 and thereby move a valve 92 to a position in which the pump putput is by-passed and the line 180 of the motor is blocked to hold the load in position. In a modification in which the motor may be required to be driven in either direction to lift the load, the cylinders of the pistons 61 are connected to the motor lines through a shuttle valve, and the valve 92 in its by-pass position blocks both motor lines.

A process for producing amylosic starch filaments comprises the steps of forming a mixture of amylosic solids and up to about 50% of water based on the weight of the mixture, subjecting the mixture to elevated temperature and pressure to convert the same into a homogeneous plastic mass, cooling the mass and then passing the mass at a temperature not exceeding about 205 F. through at least one orifice to form a continuous filament thereof and then immediately heating the filament by passing it into a drying atmosphere held at a temperature of at least 300 F. until sufficient moisture has been eliminated to render the surface of the filament substantially non-adherent. Amylose may be used as the filament-forming solid, or a derivative of amylose such as an ether, ester or anhydride thereof. Plasticizers, e.g. polyhydric alcohols such as glycerine, may also be present.
