Title: A circular knitting machine
IPC: D04B15/99
Filed: 1957-01-23
Abstract: 817,083. Knitting-machines. FIDELITY MACHINE CO. Inc. Jan. 23, 1957 [Feb. 1, 1956], No. 2419/57. Class 74 (2). Means controlling the speed of an electric motor driving a circular knitting-machine is operatively associated with pattern means governing predetermined operations of the machine, in such manner that any shift by the patterning means from one operation to another is automatically preceded by a change in motor speed. The motor speed is controlled by a potentiometer 22 when a solenoid switch 36 is not energized and by a potentiometer 23 when the switch is energized, the potentiometer 22 being controlled from the pattern drum 1 to set the motor at a high or a low speed and the potentiometer 23 being set manually to provide an intermediate speed. The machine normally runs at the high speed corresponding to the fullline position of the arm of the potentiometer 22. When a change of machine function is to occur, a lug 15, on a pattern chain 8 advanced by a pawl 11, is brought under a lever 17 to bring a bluff 19 from under a drum-racking pawl 3. The pawls 11, 3 work in alternation, being at opposite ends of a continuously operated bellcrank 6, and the succeeding stroke of the pawl 3 will thus be effective. The rocking of lever 17 has, however, closed a switch 33 to energize the solenoid switch and so set the motor at the intermediate speed under control of the potentiometer 23. The ensuing stroke of the pawl 3 brings a cam 29 on the drum 1 under a lever 31 and so, first swings the arm of the potentiometer 22, through gearing 25, 24, to the dottedline slow-speed position and secondly, through an arm 28, opens a switch 41 in series with switch 33 to de-energize switch 36 and bring the motor to slow speed under control of potentiometer 22. The length of the lug 15 is such that it remains under the lever 17 despite the next advance of the chain; and a second advance of the drum therefore occurs. During the first part of this second advance of the drum, the change of machine function is effected (e.g. change to oscillatory knitting) the length of cam 29 being sufficient to hold the lever 31 displaced during this operation; but during the second part of this second advance of the drum, the lug 29 moves from under the arm 31 so that, first the switch 41 is allowed to close to reimpose the intermediate speed, and then the arm of the potentiometer 22 is swung to high-speed position. The next advance of the chain brings the lug 15 from under the lever 17, allowing switch 33 to open; and the machine now runs at high speed again. Where it is required merely to separate two successive high-speed operations by a period of intermediate speed, the changespeed operation may be controlled by the chain without recourse to the drum. Racking of the drum may be effected in part, independently of the pawl 3, by auxiliary indexing pawls.

Filed: 1962-01-23
Abstract: 922,158. Rack-mounted electrical equipment. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 23, 1962 [Jan. 26, 1961], No. 2422/62. Class 37. In a rack for electronic apparatus containing sliding drawers carrying plug-in contacts, at least one of the drawers comprises at least two parts, each carrying plug-in contacts, arranged side by side or one above the other, and connected to one another in such a manner as to be capable of limited movement relative to one another in the sliding direction. In this way, the force required to overcome the friction between contact members when the drawer is pulled out is reduced. As shown, a drawer comprises two identical vertical frames 1 arranged side by side, and flexibly connected by four helical springs 3 which fit tightly over cylindrical projections 5 on frames 1. Each frame 1 comprises a U- shaped brace 7 to the limbs of which are welded' channel-shaped rails 9 which slide on rods 41 on the rack. Parallel vertical rails 11, 15, welded to frame 1, have horizontal saw-cuts 17 which accommodate insulating plates 19 on which are mounted components, e.g. resistors 21, the connecting leads of which are soldered to printed contacts 23 along the edges of the plates. Connection between adjacent plates 19 is by flexible conductors 26; and conductors 27 connect units to springs 29, mounted on plates 35 to form sockets which engage spring contacts 43 on the rack. Instead of helical springs 3 the flexible connectors may be tubes of elastic or plastic material, and the two front connectors may be detachable to facilitate access to the frames.

Title: Improvements in mooring masts and mooring gear for airships
IPC: B64F1/14
Filed: 1921-01-20
Abstract: 178,568. Scott, G. H. Jan. 20, 1920. Anchoring.-An airship is moored to a fitting capable of rotation about an arm carried on the top of a mast, the arm and fitting being capable of tilting in any vertical plane under the tension of the mooring-rope while the airship is being hauled into position. A tube 6 is mounted in gimbals at the apex of a conical pedestal 2 at the top of a lattice-work mast. A tube 7 slides within the tube 6, and is normallkept extended by a spring 8, spring-catches 9 preventing a complete withdrawal of the tube. A hollow cone 17 is connected to a tube 18 capable of swivelling within the tube 7, and is adapted to receive a cone 22 pivoted to a member 21 secured to the nose of the airship and capable of turning about the longitudinal axis of the airship. A hauling-in rope is payed out through the cone 17 to leeward of the mast, and is secured to a corresponding rope 24 payed out from the airship, the arm 6, 7 inclining in the same direction. The rope is then hauled in until the cone 22 engages the cone 17, in which it is retained by spring catches 25, and the hauling is continued until a collar 26 on the tube 7 is engaged by the catches 9. A pulley 23 for the hauling-rope is provided on the member 21. The arm 6, 7 is brought into a vertical position by radial wires 10 secured to its lower end and adapted to be tightened simultaneously by a pulley-block 15, radial bars being subsequently placed between the end of the tube and the pedestal 2. The rope 24 is then released and withdrawn, and a rope 28 is passed down from the airship through the tube 6, 7 and secured to a turn-buckle 29. To release the airship, the turnbuckle 29 is tightened to relieve the pressure on the catches 25, which are then withdrawn, and the rope 28 is released, for example by means of a slip link 29<a>. To prepare the arm for receiving another airship, a rope is passed down the tubes 6, 7 to the winding-gear, the rope having a conical stop engaging the cone 17 so that the tube 7 may be allowed to extend slowly as the rope is payed out after the withdrawal of the catches 9. A righting-couple may be applied to the tilting tubes 6, 7 by passing the hauling-in cable between rollers placed beneath the centre of support of the tubes, or springs or equivalent mechanism may act upon the lower end of the tube 6. The positions of the cones 17, 22 may be reversed, and the hollow cone may have a wider angle than the other. According to the Provisonal Specification, a floating mounting may be used instead of the gimbals, and electromagnetic devices may be used for securing the mooring-fittings together.

Abstract: 1491342 Lubrication system DAVID BROWN TRACTORS Ltd 20 Jan 1976 [22 Jan 1975] 2682/75 Heading F2A A lubrication system includes a pump delivering oil to a mechanism, e.g. an I.C. engine, an oil cooler interposed between the pump and the mechanism and means connected in parallel with the cooler for enabling the oil to by-pass the cooler at a rate of flow proportional to the pressure drop across the cooler, which is disposed in a housing clamped between the mechanism and the filter which is external of the mechanism, the cooler being connected to ports in the housing upstream and downsteam of the by-pass means. In one embodiment, oil is pumped from a sump to a subsidiary gallery 12 in the cylinder block 13 of an engine on which is mounted a filter 14 having a peripheral inlet 15 surrounding a central outlet 16. A cylindrical housing 17 is clamped between the block 13 and filter 14 and communicates coaxially on one end face 18 with an annular groove 19 in the block 13 into which groove the gallery 12 opens. Cooler 20 suitably disposed in front of the radiator 21 is connected by conduit 22, 23 to ports 24, 25 in the housing 17 and form respectively one end of L-shaped passages 26, 27 which open on to the end faces 18 and annular goove 28. A central aperture in the housing 17 communicates with the outlet 16 of the filter and to connect to the main oil gallery 30 in the block by a passage 29. This aperture comprises two aligned blind bores 31, 32 separated by a transverse web 33. An adjustable pressure relief valve 43 comprising a bore 44 extending from passage 26 to the exterior of the housing 17 contains a valve plunger 45 which is only exposed to the pressure of oil in the passage and is typically set to open when the pressure exceeds 10 lbs./in.<SP>2</SP>. Twin passages 52 in the housing lead directly from the bore 44 on the downstream side of the plunger 45 to annular groove 28 in the housing 17 and thus the relief valve 43 and cooler 20 are connected in parallel. In another embodiment, the relief valve 43 and bore 44 are replaced by a short bore 60 of predetermined cross-sectional area which functions as an orifice such that when the oil is cold viscose the major portion passes directly to the filter by way of the bore 60 but as the temperature increases the pressure drop across the cooler 20 decreases and an increasing proportion of the oil is able to flow through the cooler.

Abstract: 550,388. Ethyl cellulose emulsions. HERCULES POWDER CO. March 3, 1941, No. 2869. Convention date, June 27, 1940. [Class 1 (i)] [Also in Group IV] Textile material is impregnated with an aqueous water-in-oil type emulsion of a solution of an ethyl cellulose composition in a volatile organic solvent. Plasticizers may be included in the composition, e.g. dibutyl phthalate, methyl phthalyl methyl glycollate, di-(p-tert.-Butyl phenyl) mono-(5-tert.-Butyl-2-xenyl) phosphate, white mineral oil, hydrogenated methyl or ethyl abietate. The composition may contain resins, e.g. rosin-modified alkyl resins, rosin-modified terpene-maleic anhydride or maleate resins, poly-naphthalene resins, coumarome-indene resins, phenolic resins, or polyhydric alcohol esters of hydrogenated rosin. The water-in-oil emulsion may be obtained by reversing an oilin-water emulsion by addition of aluminium stearate acetic acid, pine oil-acetic acid, alkali hydroxide, or other reversing agent. It may be obtained directly by adding a reversing agent to a solvent solution of the ethyl cellulose and then emulsifying the solution in water with an emulsifying agent, or it may be obtained by emulsifying water with the organic solution with or without using emulsifying agents or protective colloids such as bentonite, gelatine, sodium lauryl sulphate, sodium stearyl sulphate, sulphonated castor or olive oil, sodium stearate or oleate or other soap, sodium isopropyl or butyl naphthalene sulphonate. In an example, an oil-in-water emulsion is obtained by agitating a mixture of ethyl cellulose, glycerol-hydrogenated rosin ester, xylol, naphtha, butanol, pine oil, and Stoddart solvent, with water containing potassium oleate. The emulsion is reversed to one of the water-in-oil type by adding glacial acetic acid and then diluted with a mixture of organic solvent and water.
