Title: Methods and apparatus for detecting and recording unevenness in the twist of plied yarns
IPC: G01N33/36
Filed: 1967-10-05
Abstract: 1,206,289. Recording variations in the twist of plied yarns. INSTITUT TEXTILE DE FRANCE. 5 Oct., 1967 [10 Oct., 1966], No. 45359/67. Headings DID and D1F. [Also in Division G3] The twist of a plied yarn is continuously detected and recorded by passing the yarn at a constant speed through a rotating untwisting spindle which has a separate guide finger for each ply so that the yarn becomes untwisted as it passes through the spindle and retwisted on the downstream side thereof, and by causing any movement of the separating point of the plies to produce electric signals which are used both to control the speed of rotation of the spindle so as to maintain the separating point substantially constant, and to make a record of the variation of twist of the yarn. The separating point is formed by an eyelet mounted on one end of a pivotally mounted lever, movement of the eyelet varying the amount a screen at the other end of the lever masks a photo-cell which produces the electric signals which are also amplified and passed to a recorder to make a trace of variation of the twist of the yarn. The retwisted yarn passes around a roller mounted on one end of a second pivoted lever and around a fixed roller, then passes to a bobbin driven at a variable speed controlled by a further screen/photo-cell arrangement mounted on the other end of the second lever so as to maintain the tension in the retwisted yarn constant.

Abstract: 1,010,426. Controlling vehicles. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN. Nov. 11, 1963 [Dec. 3, 1962], No. 45477/62. Heading B7H. [Also in Division F2] In a tractor driven by an hydraulic motor 1 supplied by an engine-driven pump 3, a cylinder 5 connected to the high pressure line: 2 between the pump and motor contains a spring-loaded piston 6 displaceable in response to pressure variation in the line 2 to actuate a lever 43 connected to the draft control valve of a powerlift linkage on the tractor or a valve controlling the brakes of a trailer towed by the tractor. Thus a pressure increase in the line 2 due to a plough carried by the power-lift encountering an obstacle can be arranged to raise the plough to relieve the draft effort, or a pressure decrease in the line 2 due to overrunning of the trailer can result in application of the trailer brakes to maintain a constant draft load.

Abstract: 1527005 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 3 Nov 1976 [31 Dec 1975] 45669/76 Heading H3B A magnetic bubble domain device is formed by applying a mask of an electrically conductive material to a continuous layer of a magnetically soft material, e.g. NiFe, which overlies a magnetic medium capable of supporting bubble domains, using the mask to selectively ion implant regions of the magnetic medium to define propagation elements, and using a critically positioned second mask to remove portions of the electrically conductive mask and exposed magnetically soft material so as to form a pattern of electrical conductors. A magnetic bubble domain store is described comprising a major domain propagation path 18 and minor storage loops 20, together with a read out zone in which a bubble B2 is stretched over a plurality of propagation paths 34. Each loop and path is delimited by an ion implanted region along the boundary of which a bubble B is moved by an in plane magnetic field. Magnetic bridges 24 link the major path and minor storage loops and further magnetic portions 28 and 30 provide a magnetoresistive detector and bubble domain annihilators. The bridges 24 and portions 28, 30 are parts of the magnetically soft layer which are screened by the mask of conductive material in the first manufacturing step. Write, transfer, stretcher and sense conductors 16, 22, 26, 29 are provided, the write conductor 16 including a partial loop portion for generating a bubble B1.

In a lathe having a bed 2 with longitudinally extending guideways 3 along which a carriage 4 traverses, a cross slide 9 is mounted on the carriage and carries a tool post 10 supporting a tool turret 25 which is indexable about a horizontal axis and carries a plurality of cutting tools 26a, the turret being provided with a plurality of supporting regions 40 around its periphery which selectively co-operate with corresponding support regions 41 on the tool post. To effect an indexing movement of the turret which is secured to a cylindrical slide 27 the turret and slide are displaced along the horizontal axis by a fluid pressure piston and cylinder assembly 30, 31, 32 thereby disengaging the co-operating support surfaces 40, 41 on the turret and tool post respectively. The turret and slide are then indexed to the next required position by an hydraulically actuated rack and pinion unit 45, 46 on the tool post. The piston and cylinder assembly 30, 31, 32 is then actuated to return the turret and slide axially towards the tool post against which they are held and at the same time effecting engagement of the co-operating supports 40, 41. The tool post and cross slide are relatively adjustable with respect to the carriage 4 and with respect to each other and are clamped in their adjusted positions by way of a holding member 14 operated by draw bolts 15 by way of hydraulic means 15a. The carriage is provided with a railed platform for the machine operator.

In a motor vehicle suspension levelled by adjusting the fluid volume in pneumatic or oleopneumatic suspension units 8a, 8b, 8m, 8n in response to detection of variations in body height by electric switches 25a, 25b, 25m, 25n, the switches 25a, 25b for the front wheels 1a 1b and the switches 25m, 25n for the rear wheels 1m, 1n are connected in series whereby the fluid volume in the front or rear suspension units is adjusted only when both front or both rear switches simultaneously detect a required adjustment in the same sense. The levelling system is energized by current supplied from a battery 26 through a main switch 27 only when the accelerator pedal of the vehicle is depressed to close contacts 28 on the pedal 29 and on an adjustable stop 28a. When a variation from the desired body height closes both switches 25a, 25b or 25m, 25n gas is either withdrawn from the suspension units and stored under pressure in a casing 9 by a compressor 13 common to the units at both ends of the vehicle, or gas from the casing 9 is admitted to the front or rear suspension units by one of electrically actuated valves ,12c, 12p. Indicator lamps 32c, 32p, 33, respectively are illuminated when the valve 12c, 12p or the compressor 13 is energized. Each suspension unit Sa, 8b, 8m, 8n includes a flexible diaphragm 6 separating a gas chamber from a liquid chamber containing a piston 3 and a partition provided with calibrated passages damping liquid movement. The compressor 13 (Fig. 3, not shown), includes two pistons 17c, 17p which work in cylinders 18 having spring-loaded inlet valves 22c, 22p and are connected to cranks 15c, 15p driven by an electric motor 14.
