Title: Yarn texturing process
IPC: D02G1/02
Filed: 1972-07-25
Abstract: 1416706 Crimping yarns ERNEST SCRAGG & SONS Ltd 20 July 1973 [25 July 1972] 34775/72 Headings DID and D1F In a twist-crimp method of texturing, an undrawn or partially drawn yarn is hot or cold drawn before (and at higher tension), during (i.e. on the twisting zone) or after it is false-twisted by passing it in contact with a plurality of overlapping friction rollers all rotating at the same speed in the same direction and interleaved in non-reversing sequence, the yarn being guided over each surface at an angle inclined to the direction of movement thereof so that the yarn is rotated with a simple rolling motion without slip. Yarn may be (further) heattreated and/or false-twisted in the opposite sense after the first false-twisting to modify the crimp extensibility and to produce non- torque yarn. The false-twister shown comprises parallel shafts 13 carrying rollers 11 with polyurethane tyres 12 interleaved in regular order and so spaced axially and rotated in the same direction at such speed that yarn passing axially through the roller assembly follows the sinuous path shown in dashed line around and between the curved edges of the rollers: the angle A is equal, at least at one point on the surface, to the twist angle for a desired twist level.

Title: Method of producing hot tops and risers, and template for making them
IPC: B22D7/10
Filed: 1955-12-05
Abstract: 778,039. Ingot-moulds; patterns; moulder's tools. DEGERFORS JARNVERKS AKTIEBOLAG. Dec. 5, 1955 [Dec. 20, 1954; March 29, 19.55], No. 34778/55. Class 83 (1). A method of making hot-tops or risers which converge towards the top-end, comprises surrounding a collapsible or demountable template with a hot-top mass or a refractory material, then folding-up or taking apart the template or lifting it out of the hot-top or riser thus formed. The template comprises plates 1, hinged to a sleeve 2, through which extends a rod 5 provided at its lower end with arms 6 connected to two opposite plates 1. The plates are preferably flexibly interconnected, and the assembly is collapsed by upward movement of the handle 4. The lower-edges of the plates 1 have a flange 12. A packing-material, e.g. asbestos, glass-wool or straw, may be provided at the bottom of the space between the mouldwall and the template, and a re-inforcement such as an iron wire may be introduced before the hot-top mass, which may be slag such as granulated blast-furnace slag, is rammed between the mould-wall and the template. The hot-top may be made by the CO 2  process. The template may be placed in the mould in such a position that part of the template extends above the top of the mould, and a collar may be placed around the projecting portion to support the hot-top mass formed therearound. When used for forming a riser, the template is positioned in a riser-flask placed on the mould.

Abstract: 393,874. Respiratory apparatus. LEMOINE, G. E., 58, Boulevard Thiers, Chaumont, Haute Marne, France. Dec. 9, 1932, No. 34963. Convention date, Dec. 31, 1931. [Class 81 (ii).] In respiratory apparatus of the closed circuit, oxylith regenerator type, the oxylith c is packed concentrically round a substantially vertical perforated tube f, mounted in fluid-tight manner on the base of a container a and having at its upper end an inlet aperture closed by sieves g, g<1> which are adapted to retain water and cause it to evaporate. The casing a is of wire gauze and the tube f communicates by way cf a chamber e with a connection d to the user's mouth. The sieves g, g<1> are subjected to the heat from the reaction and cause evaporation of moisture in the exhaled air. A fluid-tight casing h is formed at its lower part as a cooler i through which the air, after its passage through the oxylith, flows by way of conduits j. An exhaling valve q is provided at the base of the cooler. A reservoir bag n fits on the cooler and is provided with an inhaling valve r and a connection p for an air return pipe. The user wears a mask or helmet covering the nose and mouth and having an inlet valve allowing a preliminary filling of the reservoir n before entering the noxious atmosphere.

Title: Improvements in and relating to automatic radio tuning devices
Inventor: GALLETTI REMO
IPC: H03J5/14
Filed: 1955-12-06
Abstract: 807,340. Tuning arrangements for radio receivers and transmitters. MARCONI ITALIANA. Dec. 6, 1955, No. 35008/55. Class 40 (5). An automatic tuning arrangement for a radio receiver or transmitter comprises a motordriven variable-frequency oscillator connected to an output circuit and a fixed-frequency resonant means having its resonant frequency within the range of tuning of the oscillator and arranged so that a relay operates when the oscillator frequency reaches the fixed frequency operation of the relay causing the motor to stop, the fixed frequency resonant means to be connected into a fixed frequency oscillator circuit and the output of the fixed oscillator to be connected to the output circuit in place of the variable oscillator. In the Figure an oscillator 1 is connected to an output circuit H.F. by a lead O and has its tuning adjustable by manual control or by a motor 2. For manual operation a switch 6 is moved to position N but for automatic control the switch is moved to connect to one of the crystals Q1, Q2, Qn, whereupon a switch 11 is operated to start the motor. The oscillator output lead O is connected to the grid of an amplifier valve 4 connected to the crystal and when the oscillator frequency reaches the resonant frequency of the crystal sufficient output passes through the crystal to a rectifier 8 to operate a gas-filled relay circuit 23, 25, 3 and so change over the contacts of a relay 3. This breaks the motor circuit at contact 15 and at contacts 13 and 15 connects the crystal in the feedback circuit of the valve 4, causing it to oscillate. At the same time the H.T. circuit for the oscillator 1 is broken at contact 14 and the oscillation output from valve 4 is connected through contacts 12 to the receiver in place ,of the variable output from the oscillator 1.

A load lifting and lowering arrangement comprises a rigid framework including vertical guides 2, a lifting slide 3 mounted for movement up and down within the guides 2, and a load supporting platform 4 hinged on pins 21 on the lower end of the slide 3 so that it can either be " unfolded ", i.e. swung into a horizontal working position or swung up into a " fully folded " inoperative position. Power means, such as an hydraulic cylinder and ram device as described in Specification 1,082,925, is connected with the slide 3 for raising and lowering the same through the medium of cables (not shown) and sets of appropriately disposed pulleys and is provided with a connecting element in the form of a steel cable 8 to enable the platform 4 to be folded up under power. As shown, applied to the tailgate lift mechanism of a road vehicle (not shown) the cable 8 is normally retracted through an apertured guide 12 into the vehicle body by a tension spring 14. When the platform 4 is to be folded up the slide 3 is fully lowered, the cable 8 pulled out and its outer end connected to the platform 4 by a hook 10 and eye 9. The slide 3 is then lifted under power and a pulley 11 on the slide engages the cable 8 folding the platform 4 into its inoperative position where it may be retained by catch means 16 mounted on the guides 2 and the slide 3. The platform 4 is of the linkless type and cantilevered with a block 22 associated with each hinge pin 21 to limit the downward pivoting movement to the horizontal operative position.

A fire extinguisher nozzle comprises a tubular body 1 provided with a valve seat 4, a sleeve 9 surrounding the body 1, and a nylon valve member 5 having a tubular extension which is formed at its downstream end with a jet orifice 17, the arrangement being such that rotation of the sleeve 9 causes the valve 5 to move axially away from its seat 4 into a position in which liquid is discharged as a spray between the sleeve and the tubular extension, and further rotation of the sleeve, Fig. 3 (not shown) allows liquid to enter radial ports ,15 whereby it is discharged through the orifice 17 as a central jet. The valve is prevented from rotating by a pin and slot device 8 and a pair of spaced sealing rings 6, 7 on the valve cooperate with the body 1 to prevent leakage and control the liquid flow when the valve is adjusted in position. When the valve is moved downstream of the Fig. 3 (not shown) position in which a spray is discharged coaxially with a jet, a jet only is discharged, Fig. 4 (not shown). In the modification of Fig.  5 (not shown), the nozzle is adapted to discharge either a jet or a spray.
