Title: Skip Stitch Attachment for Zigzag Sewing Machines
IPC: D05B81/00
Filed: 1967-08-01
Abstract: 1,189,181. Sewing machines. SINGER CO. 1 Aug., 1967 [23 Aug., 1966], No. 35182/67. Heading D1G. An attachment for use with a zig zag sewing machine comprises a clamp for attachment to the needle bar, and a two-armed lever pivoted on the clamp, one arm being adapted to contact a portion of the sewing machine to rock the lever during the downward stroke of the needle bar in one of its lateral positions to enable the other arm to nip the needle thread to prevent stitch formation. A U-shaped member 57 is clamped to the needle bar 29 by a screw 58. A wire lever 59, pivoted at 62 to member 57 in front of the needle bar, has an arm 64 extending rearwardly past the presser bar 52, and a forwardly-extending arm 68. Arm 64, being longer than arm 68, normally engages the upper surface of member 57, when arm 68 is separated from the front surface of member 57. Thread 74 on its way to the needle 36 passes between member 57 and arm 68, and through an eyelet 72 formed at the lower end of a coil spring 71 depending from member 57. When the needle bar is in its left hand position, arm 64 is separated from the presser bar and stitches are formed normally. When the needle bar is in its right hand position, arm 64 engages the needle bar and thereby moves upwardly when the latter descends, for gripping thread between member 57 and arm 68. Said gripping, in conjunction with the action of spring 21, keeps the thread to the needle eye taut and thereby prevents the formation of stitches. Use of the attachment with a pattern cam providing a plurality of right hand needle penetrations for each left hand penetration, will thereby produce long basting stitches.

Title: Improvements in or relating to a method of regulating steam pressure and a thermal excess-pressure device or "pressurizer" employing said method
IPC: G21C1/09
Filed: 1966-08-09
Abstract: 1,121,984. Regulating steam pressure in expansion vessels. COMMISSARIAT A L'ENERGIE ATOMIQUE. 9 Aug., 1966 [30 Sept., 1965], No. 35699/66. Heading F4A. [Also in Division G3] A pressurized water primary circuit of a power generating installation (not shown) is provided with a closed expansion vessel 1. When the power demanded from the installation decreases, the resultant increase in temperature of the water in the primary circuit causes it to expand along conduit 2 and enter the vessel 1 which contains steam and water phases maintained in equilibrium at a higher temperature than that of the water in the primary circuit, by controlled heat source 7. To obviate the pressure increase in the vessel 1 which would otherwise occur when the expansion water from conduit 2 enters it, part at least of this cooler water is passed through a heat exchanger 6 in the steam phase before being discharged into the vessel through orifice C, so cooling and condensing some of the steam. When the power demanded from the installation increases and the water in the primary circuit contracts, water passes from the vessel 1 to the primary circuit through orifice B, and non return valve 4. The resultant pressure drop of the steam in the vessel 1, is partly offset by evaporation of some of the hot water remaining in vessel 1, so reducing the pressure variation.

Filed: 1956-11-22
Abstract: 816,568. Fluid-pressure servomotor-control systems. HOBSON Ltd., H. M. Nov. 21, 1957 [Nov. 22, 1956], No. 35788/56. Class 135. In an hydraulic servomotor system in which the piston valve 17 of a power output device, such as a jack 18, is controlled by a hinged plate 12 disposed between two control jets 13, the member 12 is also subjected to the action of two further, velocity feedback, jets 26 so arranged that upon operation of the power piston 19 one of the jets exerts a force opposing the displacement of the member 12. As shown, each end of the power cylinder is connected to the exhaust pipe 23 through a pipe 22 incorporating a restriction 25, the associated jet 26 providing an alternative flow path. Assuming, for example, that the member 12 is displaced clockwise, valve 17 and piston 19 both move to the right, and a portion of the liquid displaced from the righthand end of the power cylinder is discharged through the left-hand nozzle 26 to oppose the displacement of member 12. As shown, the latter is operated by electrical signals through an amplifier 11 and transducer 10, the piston 19 being associated with a potentiometer 20 for sending position feedback signals to the amplifier 11.

Title: Liquid flow rate meters
Inventor: IFIELD RICHARD JOSEPH
IPC: G01F9/00
Filed: 1953-12-24
Abstract: 755,716. Liquid meters. LUCAS (INDUSTRIES), Ltd., J. Dec. 1, 1954 [Dec. 24, 1953], No. 35879/53. Class 69 (2). A liquid meter comprises a body a having three cylinders, one containing a metering piston n, one containing a rotary valve d, and the third containing a piston t which, when the flow is not to be measured, is moved by the liquid thereby compressing a spring u and connecting an inlet b to an outlet c. The valve has a part i which is driven by a synchronous electric motor. The valve is divided into two equal parts by an oblique partition e and has an outlet g connecting one half of the valve with one end of the cylinder of the piston n and has another outlet h connecting the other half of the valve with the other end of the cylinder of the piston n. The stroke of piston n is controlled by a pre-set abutment o and by a stop p adjusted by a micrometer head q. To measure the flow, the stop p is unscrewed to give the piston n a maximum stroke, and the valve d is driven by the electric motor. The piston t will be moved by its spring to close the direct connection between the inlet and outlet and the whole of the flow will pass via the valve d and the piston n to the outlet. The stop p is then screwed in, reducing the stroke of the piston n, and the increase in pressure will move the piston t until the end of a rod 4 carried by the piston coincides with a mark 6 on a transparent cover 5. In this position, the head of the piston t corresponds with the edge of a port 2 leading to the outlet side of the meter, and the micrometer reading gives the flow.
