Title: Magnetic devices
IPC: G11C19/08
Filed: 1972-05-02
Abstract: 1387853 Moving domain devices WESTERN ELECTRIC CO Inc 2 May 1972 [6 May 1971] 20337/72 Heading H3B In a bubble domain device the propagating elements are such that at a given location in the propagation path the domain enlarges to provide a larger output signal when a magnetoresistive reading device is used, and also to allow the propagation path to change direction with out loss of stability. Fig. 1 shows a path defined by Y bar elements, and propagation is controlled by a rotating in plane field. In region 17 the path undergoes a 180 degree change of direction, having a semicircular element 18 off which radial elements 21-25 lead. A domain arrives at the bottom of element 21 when the in plane field H is downwardly directed as shown by the arrow in Fig. 1; as the field rotates clockwise 180 degrees poles appear in succession on the ends of the other radial elements to stretch the domain and pull it along element 18. Fig. 2 shows how this domain D0 appears when the field has rotated 120 degrees, and also shows the position of the next domain D1. Fig. 4 shows that D0 leaves the semicircle before D1 enters it, and the direction change of the path is accomplished in one cycle of the propagating field. As a result of this the domain spacing is maintained during the change of path direction and stability is not impaired. Fig. 1 also shows conductors 40, 41 which pass a current through the element 18. When a domain is present the (magneto-)resistance of the element changes and the resulting current change forms an output. If such a detector is not required, the common element 18 may be dispensed with, the domain being enlarged by a diffuse pole formed of parallel bar elements such as those shown in Fig. 7. When the detector is used, the common element is relatively thin to provide a suitable resistance. The magnetic domain material may be a 4.5 Á slice of europium erbium gallium garnet deposited on a gadolinium gallium garnet substrate. A bias field of 90 Oe. produces 4 Á domains. The Y-bar overlay is permalloy on an SiO 2  film, while the in-plane field is of value 20 Oe. and rotates at 100 KHz. The common element 18 of Fig. 1 may be a flux concentrating lamella of permalloy, chromium and permalloy. The bubble domains may be created in known manner from a magnetically soft disc on the garnet slice, and destroyed in similar manner.

Title: Improved method and apparatus for ultrasonic shearwave inspection
IPC: H03K3/78
Filed: 1960-06-09
Abstract: 945,616. Ultrasonic flow detection; triangular wave generators. BRANSON INSTRUMENTS Inc. June 9, 1960 [June 9, 1959], No. 20352/60. Headings H3P and H4D. Ultrasonic flaw detection apparatus comprises time marker signals having a triangular waveform with substantially equal periods of linear rise and decay and means for modulating the displayed marker signals with echo signals. Clock pulse generator 32 is connected to pulse transmitter 34 via delay multivibrator 33 to permit cathode-ray tube (C.R.T.) sweep and marker switching pulse 46 to be triggered before transmission if desired; longitudinal vibrations from piezo-electric crystal 35 are transmitted through plastic wedge 36 and an oil or cement couplant to the test piece wherein transverse vibrations ensue. The C.R.T. sweep is initiated coincidentally with, or before, the pulse from transmitter 34 by delay multivibrator 33 and a switching pulse for triangular wave generator 47 is derived from multivibrator 46 which is triggered by adjustable-delay multivibrator 45 and the differentiated lagging edge of the sweep saw-tooth. Initial pulse 56 precedes the first cycle of triangular wave 31 by an amount corresponding to the transit time through the wedge and the delay in multivibrator 45 is so adjusted. Location of flaws in the test piece is thereby accurately and readily provided. The frequency of the triangular wave is adjustable, to allow for different path lengths in test pieces and for differing velocities of wave propagation. The sweep speed is adjustable to allow for different test piece lengths. The triangular wave generator 47 is described in detail, Fig. 4 (not shown), and forms the subjectmatter of Specification 945,617. Specifications 633,827, 641,095 and 663,064 also are referred to.

Abstract: 1473583 Modulating valves SOC ANON FRANCAISE DU FERODO 17 May 1974 [24 May 1973] 22050/74 Headings F2F and F2V In a modulating valve assembly 15 a chamber 24, communicating with an hydraulic pressure producing device, is communicable with a chamber 26, communicating with an hydraulic pressure receiving device, via a normally closed pressure regulating valve member 29 controlling flow through a passage 28 and a normally open isolating valve member 41 controlling flow through a passage 37 axially within the member 29; a piston 45 having a face communicating with the chamber 26 has at least one passageway 47 extending therethrough and abutment means 46 extending and urged towards the valve member 41, a further piston 60 being axially remote from the chamber facing face of the piston 45 and being engageable by an electromagnet 50 for movement towards the piston 45 upon electromagnet actuation. Specification 1,472,674 claims a different aspect of the disclosed assembly. Fig. 2 indicates the modulating valve assembly allowing uninterrupted hydraulic flow from a master cylinder via a line 25, the chamber 24, the passage 37, the chamber 26, and a line 27 to brake actuators. Upon receipt of a skid signal, an armature 51 of the electromagnet 50 moves rightwardly towards a yoke 49 to close an air gap 52, and in doing so, moves a needle closure member 63 and the associated piston 60 to open communication between the chamber 26 and a line 72 via the passageways 47 and a chamber 70. The passageways 47 produce a pressure difference between the chambers 26 and 70 causing the piston 45 to move leftwardly, allowing the member 41, e.g. a ball or disc, to close off the passage 37, pressure in the chamber 26 then being reduced by flow to the line 72 which leads to an accumulation chamber 73 bounded by a piston 79. This decrease occurs until a rod 62 is engaged by the piston 45 to close the line 72 by the member 63, against the armature force. Upon cessation of the skid signal, the armature 51 moves leftwardly, with consequential rightward movement of the piston 45 which contacts the closure member 41; however, the member 41 moves with the closure member 29 as a unit, opening communication between the chambers 24, 26 but via an orifice 31 and a chamber 24B, this action being controlled by a spring 80 in turn controlled by the piston 79 and the fluid in the accumulation chamber 73. This action continues until the member 41 opens up the passage 37. Fig. 10 shows the member 41 replaced by a sleeve with a stop washer 101.
