Title: Improvements in or relating to cast-off mechanism for knitting machines
IPC: D04B15/32
Filed: 1934-04-11
Abstract: 433,737. Knitting-machines. HOLMES, H. H., and WILDT & CO., Ltd., Adelaide Works, Leicester. April 11, 1934, No. 10952. [Class 74 (ii)] Means for entirely casting off stitches from selected needles, as in welting, consists of a cast off cam, operatively connected to a needle-raising cam so that the two may be simultaneously and complementarily adjusted. When the needle raising cam 11, Fig. 1, is raised to clearing position (chain lines) by means of pattern mechanism acting on a slide 13 connected thereto, a rocking lever 21 depresses the cast-off cam 15 to cast-off position, against the action of a spring 18. The slot 19 in which one end of the rocking lever works, permits some lost motion. A slide 32 also pattern controlled, engages a latch 14 on the slide 13 to hold it raised. In a modification, Fig. 2, the needle raising cam is formed by a lever 23, pivoted at one end to a spindle 24. A radially movable bolt cam 26, chamfered at its inner end, engages, when pushed in, a cam lever 25, and so tilts the lever 23 to the position shown chain-dotted, it being retained in this position by a spring- controlled check plunger 27. As the lever 23 is raised a rocking lever 28, one of whose ends rides on a cam surface on the cam lever 25, is tilted clockwise and depresses the cam 15, as before, against the spring 18. The raising cam may be lowered to run-level, and thus the needles may pass the cast-off position without disturbance.

[Class 7 (iv)] [Also in Groups II and XXII] In a sparking-plug the central electrode 10 has a sparking end 14 of loop or toroid shape through which extends the earthed electrode 16 in the form of a rod which is secured to the outer casing 12 at both ends or at one end only. The sparking end is preferably secured by welding, but in Fig. 3 the loop 34 is brazed in a bore in the end of conductor 30, the electrode 16 being brazed to the casing. Alternatively the ends of a loop 50, Fig. 5, may be butt-welded and then attached to the central conductor 51 or the loops may be prepared by powder metallurgical methods; they may also be stamped from a blank of electrode material. Preferably either one or both electrodes consist of a core 17 of metallic composition having high thermal and electrical conductivity and a sheath having a relatively high melting point and good resistance to pitting, oxidation, corrosion &c. the coefficients of thermal expansion of the two substances being approximately equal. The core may be formed of copper or silver compositions and the sheath of austenitic iron alloys containing between 14 and 36 per cent. of one or more of the elements-chromium, nickel and manganese, in addition to the usual carbon content. Typical examples of these compositions are (a) stainless steel with 18 per cent. chromium and 8 oer cent. nickel, (b) steel with about 24 per cent. nickel and the balance mainly iron, (c) steel containing 14 per cent. manganese, 1 per cent. carbon and the remainder mainly iron. The sheath may also be formed of pure nickel or its alloys; cobalt or chromium base compounds ; platinum or palladium and their alloys. The loop may be hot-punched from strips of tungsten. or from tungsten base alloys using powder metallurgical methods. Another method is to punch the core from strip or butt-weld it from wire and then electroplate it with nickel or platinum group metals and alloys, or rhenium or tungsten group metals.

Abstract: 396,343. Ships' steering gear. DEUTSCHE WERFT AKT.-GES., Postfach, 889, Hamburg, Germany. April 18, 1933, No. 11286. Convention date, April 28, 1932. [Class 114.] In hydraulic steering- gear in which shocks caused by blows from the sea on the rudder blade are absorbed the shock-absorbing means comprises a balancing device normally held in central position by spring means and connected in parallel with the fluid pressure system such device being displaceable to absorb shocks in such a manner that the quantity of pressure fluid on each side of the system remains constant. As shown in Fig. 1, a balancing or shock-absorbing device, which is connected in parallel with the operating cylinders c, c<1> and pistons b, b<1> of the rudder, comprises cylinders g, g<1> and a piston d controlled by springs f, f<1>. External shock on the rudder sets up a pressure in one or other of the cylinders c, c<1> which pressure forces the piston d against one or other of the springs f, f<1> to absorb th shock. In other arrangements the springs f, f<1> may be arranged externally and the cylinders g, g<1> may be movable with the piston or pistons stationary. Fig. 5 shows the device employing one spring f only, a reduced part r of the piston passing through loose discs s, t and the spring f. The discs s, tare apertured so that pressure is uniform throughout the cylinder g ; excess of pressure in that cylinder forces the piston d out of the cylinder against a compression of the spring f. Fig. 6 shows hollow pistons h, h<1> connected together by bars k and adapted to operate the rudder through the springs f, f<1>. Shock on the rudder forces one or other of the pistons b, b<1> into the hollow piston against spring pressure, the interior of the hollow pistons being in communication with the atmosphere through grooves m, m<1>.

Abstract: 117,164. Matthews & Yates, Yates, W., and Pougher, E. W. Aug. 7,1917. Valves and valve apparatus.-In ventilating, dust-removing, and like apparatus, valves provided in the air conduits are normally held open by gear comprising a fusible element, which allows the valve to close in the event of overheating of the air within or around the conduit. The valve b, Fig. 2, is enclosed within a dust-proof casing a. and is normally held open by a pivoted catch f, which engages a circular groove in the one face of the valve. The free end of the catch carries a roller g, and over this passes a flexible wire or the like h, connected at one end to a weight or spring, and having in its length one or more fusible links, either within or outside the conduit. When a link fuses, the valve closes by its own weight. An asbestos or like seating j is provided in the conduit, and the edge of the valve may be provided with a circumferential V-groove. In a modification, Fig. 7, the dust-proof casing is arranged at the side of the conduit, and the valve is operated by a weight m through a wire rope k. The weight is normally held by a catch n, the free arm of which carries a pulley o around which passes the wire h with the fusible links. A catch p may be provided to lock the valve in its closed position, and a spring q may be interposed between the rope k and the weight. The fusible element may consist of a link i, Fig. 12, made in two parts, the abutting ends of which are formed with peripheral grooves for the reception of the fusible material. The grooved parts may be surrounded by a protecting collar 5.

IPC: B43K19/16
Filed: 1919-05-07
Abstract: 149,072. Marks, E. C. R., (American Lead Pencil Co.). May 7, 1919. Pencils.-Pencil leads and similar material are formed as plastic rods by extrusion through orifices, and are then delivered upon a carrier and subjected to heat or other drying agent, the carrier being provided with means for straightening or preserving the straightness of the rods while drying. Fig. 7 shows an extrusion device producing several rods 23 from a thick ribbon 24 at each stroke of a plunger 21. The ribbon 24 is fed intermittently across the path of the plunger to an extent determined by a spring-projected supporting-lever 27, which is tripped by a projection 32 on the plunger 21, and is angularly adjustable to regulate the feed. The extruded rods 23 are received in grooves 45, Fig. 4, in a transferring- cylinder 44, which is advanced intermittently by pawl-and-ratchet mechanism, and delivers the rods over the end of a shield 58 to a transverse carrier on which the rods are dried. The rods are cut off adjacent to the orifices by the, edges of the grooves 45, and are preferably made long enough to project at the other end of the cylinder 44 for trimming by a stationary knife. The transverse carrier may be grooved to receive the rods and advanced intermittently. In the arrangement shown in Figs. 4 and 8 the transverse carrier comprises three conveyer bands 65, 66, 67, preferably of absorbent material, running over heated tables 59, 60, 61. A preliminary drying under close confinement is given on the table 59 under a band 80, and subsequently on the tables 60, 61 the rods are exposed to the open air. The bands 65, 80 may be run at different speeds to give slow continuous rotation to the rods. On the tables 60, 61 intermittent rotation is imparted to the rods by means of friction bands 85, which are fixed at their forward ends and lie loosely on the conveyer bands. The bands 85 are preferably loaded at intervals by means of slats attached to their upper surfaces. The tables are disposed at different levels so that the rods fall a short distance from one table to the next, to corect small divergencies from parallelism. The dried rods are discharged upon a delivery band 88, on which the ends of the rods are trimmed by knife-edge disks 92; horizontal disks 98 aline the rods on the band 67 in relation to the cutting-disks. Reference is made to Specification 143,073.

Abstract: 595,095. Colour kinematography. BASSANI, L., and GAGNEPAIN, G. May 4, 1945, No. 11445. Convention date, Dec. 22, 1944. Drawings to Specification. [Class 98 (ii)] In a colour kinematography process using lenticular films, a positive film is printed by contact from a negative and during projection the colour filter is subjected to an oscillating movement. The object is to compensate for the random lack of registration of the positive and negative films during printing and the amplitude of the oscillation corresponds to the mean displacement of the images in the positive film required to bring them into proper registration with the lenticles. The oscillation employed is a circular translational movement. In a modification, the colour filter in the camera is also oscillated and the movement of the filter in the projector is a corresponding oscillation. A mechanism, for producing the oscillations, is described, using cranks of variable throw with micrometer adjustment. Specification 222,872, [Class 98 (ii)], is referred to.

As shown, closure of operating switch 118, 119 turns on transistor 123 to energize relay coil 110, thereby connecting the motor 114 to the supply over contacts 111, 113. The coil remains energized until capacitor 124 is charged via 128, 127 and the multivibrator switches over. The time constant for this is more than long enough for the motor to start and change over the contacts of parking switch 115-117, and this switch short circuits 128 via diode 120, thus shortening the time constant so that the relay coil is de-energized before a single wipe has been made. Hence the motor stops when the parking switch operates to short circuit the motor and thereby brake it. The cycle is repeated when the m.v. again switches over, after a time determined by adjustable resistor 129.
