Title: Method of making pile fabrics having loops of different height
Inventor: CRAWFORD ALLAN HUGH
IPC: D03D39/02
Filed: 1957-05-03
Abstract: 825,581. Tufting machines. MOHASCO INDUSTRIES Inc. May 3, 1957, No. 14187/57. Class 112 A method of producing a pile fabric in which the height of the tufts is varied according to a pattern comprises advancing a backing sheet, feeding a length of yarn controlled in accordance with the pattern, taking up a fixed length of the yarn so fed into a storage zone, withdrawing a fixed length from the zone and inserting it into the backing sheet to form a loop and repeating this cycle indefinitely to form the fabric, the taking up of the fixed length of yarn into the zone in a cycle in which the controlled length of yarn is shorter than that required to form a tuft of maximum length causing the yarn to be drawn from the loop inserted through the backing sheet in that cycle. A multineedle tufting machine for prosecuting the method comprises a storage zone defined by yarn guides 24, 25 into which the yarn Y is taken up and withdrawn, as the needle rises and falls respectively, by a deflecting bar 69 attached to the needle bar 18, and yarn feeding means comprising two interleaving series of pattern elements 31, 43 carried on endless chains 32, 44 respectively. A sheet of yarns, one yarn for each needle, passes between the interleaving pattern elements the height of which are varied according to the desired pattern so that each feed increment, the wavelike length of yarn between two adjoining elements 43, has a length corresponding to the pattern. The chains are driven in synchronism with the needle so that a leading feed increment of each yarn is released for each needle cycle and simultaneously a further increment is drawn into the feeding means from the supply creels. As the needle descends a fixed length of yarn is also released from 'the storage zone 24, 25, the sum of these released lengths being available to the needle to form a tuft in the backing sheet 12; as the needle rises the fixed length is taken back into the storage zone leaving a tuft of a height corresponding to the controlled length of yarn fed. Each pattern element may vary in height along its length so that the line of tufts produced by a descent and rise of the needle bar may vary in height along the row. Specifications 825,582 and 825,583 are referred to.

Inventor: LAWRENCE OWEN NAPIER
IPC: F23K5/00
Filed: 1951-06-15
Abstract: 710,108. Gas turbine plant; jet propulsion plant. LUCAS (INDUSTRIES), Ltd., J. June 5, 1952 [June 15, 1951], No. 14271/51. Class 110(3) [Also in Group XI] In a gas turbine or jet engine fuel system; in which fuel is supplied to spill type burners by a pump and returned to the system by means of a second pump, the second pump is driven by an electric/motor which is controlled by a switch responsive to, the fuel pressure in the system. Fuel is supplied by a pump b to a spill type burner or group of burners a and the excess fuel is returned to the system from the swirl chambers by a pump d. The pump.d d is driven at constant speed by an electric motor e which is controlled by a normally closed switch f. The switch f is operable by a spring loaded diaphragm or piston g. The arrangement is such that at low or medium load, fuel is circulated by the pump d but under full load conditions, the fuel pressure acting on the diaphragm g opens the switch and puts the pump d out of action. To enable, the pump d to be used to prime the system; a valve j, comprising two non-return members k, is provided. When the switch n is closed the pump d draws fuel from the supply tank through the lower member k. As soon as the pipe between the -pump b and the burner a is full, the pressure of the fuel opens the upper member k and closes the lower member k and the pump d then circulates fuel through the burner a. A fuel control valve o is also provided for regulating pur. poses. In a modification, the valve j is replaced by a piston valve which is also actuated by the diaphragm g. In afurther modification a spring loaded plunger operated by the pressure of the fuel supply is used to control a variable resistance incorporated with the pressure responsive switch in .the supply. to the electric motor e so that the speed of the motor is progressively reduced to zero as the fuel pressure increases.

Abstract: 1455417 Mechanical switches; retractive switches LUCAS ELECTRICAL Ltd 28 Feb 1974 [28 March 1973 8 June 1973] 14797/73 and 27535/73 Headings G4Q Q1D3X and Q4G2 The operating member 21, 15 of a direction indicator switch is movable into its operative positions by pivoting about two parallel, spaced axes 13, 14, and latched in each of its operative positions. Slots 16, 17 in member 15 allow the pivoting. The latching is achieved by pawl 22, pivoted and spring-loaded to its central position on member 15 and lugs 23, 24 upstanding from base 11. When member 15 is pivoted clockwise (about pin 13), pawl 22 engages the edge of lug 24 then experiences inward movement due to member 15 pivoting about pin 13 so that an edge 25a of a recess in the lower side of pawl 22 rides up the side of lug 24 and slides over and engages the edge 24a of lug 24 to hold member 15 in its operated position. Return movement of the steering wheel causes striker 27 on shaft 12 to free pawl 22 so that springs 19 return member 15 back to its central off position. A handle 21 is released when pawl 22 first abuts the side of lug 24 (at which point the contacts are made), springs 19 return member 15 to its central position. The operation is similar if member 15 is pivoted anti-clockwise except that pawl 22 engages lug 23 having surface 23a. Member 15 can be manually released from its latched positions by returning handle 21 to its central position. In a modification, Figs. 4, 5 (not shown) lugs (123, 124), corresponding to lugs 23, 24 in Fig. 1, are depressible against restoring springs to permit manual cancellation even if striker (127) has engaged pawl (122) and is preventing its movement.

Title: Process for the electrolytic production of dialkyl magnesium and trialkyl aluminum compounds
IPC: C25B3/13
Filed: 1960-04-29
Abstract: Magnesium dialkyls and aluminium trialkyls are prepared by electrolyzing a melt of MeAlR4, where Me is Na or a mixture of Na and K, R4 is alkyl containing 2 to 6 carbon <PICT:0946686/C3/1> atoms, using an inert cathode, and aluminium or magnesium as anode, and keeping the free metal alkyl content in the cathode zone below 3%, e.g. by operating in vacuo when the metal alkyls distil off, or by using solvents, e.g. a saturated aliphatic or aromatic hydrocarbon. When using a magnesium anode a loose complex of magnesium dialkyl and aluminium trialkyl is formed in the anode area, and rises to the surface as a separate layer. This is removed by distillation at low pressure or by extraction with hydrocarbons and the resulting complex is easily separated by heating, the aluminium trialkyl distilling off leaving the magnesium compound. Electrolysis is effected in an inert atmosphere at 0.5 to 5 Volts and at 100-140 DEG C. In a suitable apparatus containing an inert gas, the molten electrolyte is introduced into an opening 1, and magnesium or aluminium granules through an opening 2.  Sodium is deposited on the copper cathode 8, and is withdrawn through an opening 3.  The cathode 8 is separated from the anode by a diaphragm 7, e.g. of glass fibre or cloth.  The tri-alkyl aluminium or dialkyl magnesium rises and is withdrawn at 6. The temperature of the catholyte is controlled by a heating element 9, and the anolyte by re-circulation through a pipe 10. The liquid level in the cathode space is 4 to 5 cm. higher than the anolyte, whereby catholyte overflows through an opening 5.  Solid aluminium anodes may be used.  The apparatus is connected to a cooled receiver, the cell being maintained at 130-140 DEG C. at 1 mm. Hg. pressure. Specifications 763,824, 814,609, 848,364, 864,393 and 864,394 are referred to.

Title: Improvements relating to furnace control systems
IPC: F23N1/02
Filed: 1935-05-24
Abstract: 457,277. Fluid-pressure servomotorcontrol systems. SMITH, G. W., 1121, Wightman Street, Pittsburg, U.S.A. May 24, 1935, No. 15184. Convention date, May 25, 1934. [Class 135] [See also Group XII] In a furnace control system, a damper or the like is operated by the variation of pressure produced in a conduit between a variable orifice and a fixed orifice, the fixed orifice being open to the furnace at a given point and the variable orifice being open to an approximately constant source of pressure and adjusted by means responsive to a condition, such as steam pressure, requiring a change in the rate of combustion. In the form shown in Fig. 1, a pipe 9 is connected at one end to the furnace outlet and at the other end to the atmosphere through a variable orifice 12. Between the orifice 12 and fixed orifice 11, the pipe 9 is connected to one of a pair of inverted bells 16, 17, of a regulator 6, the other bell being open to atmosphere. The fulcrumed beam of the balls rocks with changes of suction in the furnace and thereby operates a motor 7 to control a stack damper 5. The beam is loaded by a weight w to give a balance at the required value of the suction. The variable orifice 12, Fig. 2 comprises a body having an opening 36 controlled by a valve 37 actuated in accordance with the steam pressure in the main header 4 acting through a master control 100, a proportioning relay and pipe 13 on one side of a diaphragm 43. A damper 54 in the air supply conduit is controlled, through apparatus similar to the regulator 6, in accordance with the pressure within the furnace and is therefore indirectly controlled by the demand for steam. The fuel feeding apparatus 2 is controlled by a regulator 58 in accordance with the steam demand. In a modified form the orifices 11, 12 and the regulator 6 are used to control a damper in the air supply conduit between the fan and the damper 54. In a further modification in which the furnace may be fed with two different kinds of fuel, for example, solid and gaseous, the pipe 9 is provided with two variable orifices, the pressures in the steam connections thereto being used to control the different fuel supplies.
