Title: Carrier for a scanning head confronting rapidly passing work pieces
IPC: G01N29/27
Filed: 1964-12-24
Abstract: 1,084,510. Ultrasonic inspection devices. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Dec. 24, 1964 [Dec. 27, 1963], No. 52506/64. Heading H4D. [Also in Division F2] An arrangement for maintaining the scanning head of an ultrasonic inspection-apparatus in contact with the undulating surface of a rapidlymoving workpiece, such as sheet metal from a rolling-mill, includes at least two elastic systems of different rigidity and interconnected by an inertial mass. A piezo-electric transducer (26) is attached to a frame 1 by rubber or foamed plastic blocks (27) and leaf-springs (28) (Fig. 2). The frame 1 is hinged at 2a to a double-armed lever 3 pivoted at 4, and the lever 3 is connected by a spring 7 and a pneumatic or hydraulic damper 9 to a second pivoted lever 14. Lever 14 pivots against the action of a spring 18, and its moment of inertia about the pivot may be adjusted by moving a mass 16 along a rod 15. The spring 18 exerts a static force to hold the scanning head against the lower surface of the work-piece and also exerts a dynamic force enabling the head to follow low-frequency (#1 c/s.) undulations of the workpiece. For higher frequency undulations (#10 c/s.), the mass 18 behaves as a fixed point and the undulations are absorbed by the spring 7 and damper 9. Still higher frequency undulations (# 30 c/s.) are absorbed by the highly flexible system comprising the blocks 27 and leaf-springs 28, both levers 3 and 14 being effectively fixed due to their inertia. Rollers (25) (Fig. 2), locate the transducer (26) with respect to the surface of the workpiece, and water is circulated around the transducer (26) as a coupling medium. The scanning head may be lowered out of contact with the test-piece by an air-jack 21. Details of the damper 9 are given.

Abstract: 1,206,525. Multi-layer extrusion; extrusion dies. AMERICAN CAN CO. 6 Nov., 1968 [27 Feb., 1968], No. 52682/68. Headings B5A and B5B. In a method of extruding a multilayer thermoplastic film using a die having a separate flow passage for each of the layers which converge in a common passage within the die, the flow passages can be individually restricted to adjust the amount of material flowing in the passage(s) and the relative amounts of the different thermoplastic materials entering the common passage. In a preferred embodiment for extruding a three-layer film of two resins comprising an intermediate layer of polyethylene and outer layers of polypropylene, three separate screw extrusion units 21, 22, 23 are arranged to feed into a single elongated extrusion die. Each unit has a central inlet port 24 and an elongate manifold 25 connected to a source of molten resin and a narrow flow passage 26 which follows a serpentine path leading from the manifold and intersecting with the passages from the other two manifolds in common outlet passage 28. A manually adjustable restrictor bar 27 is set into and forms a part of one wall of the flow passage between manifold 25 and outlet passage 28 and controls the flow from the manifold. The position of bar 27 can be adjusted by rotating the nuts 32 carried on the ends of a row of threaded studs 31 which extend through the die section. A die lip assembly 33 mounted on the bottom of the die body comprises a pair of die lips 34, 35, and defines a continuation 28a of outlet passage 28. Left-hand lip 34 is constructed for flexure so that the die slot may be adjusted by a row of screws 36. The multi-layer extrusion die is thus capable of two separate adjustments, (i) an overall adjustment for gauge control of the composite film by means of die lip assembly 33 and (ii) individual adjustment of each flow passage 26 by means of restrictor bars 27. The extrudate may be delivered to a chill roll, as shown, or directly on to a web substrate.

Title: Rotary inductive transducers
IPC: G01D5/20
Filed: 1972-11-24
Abstract: 1414517 Rotary inductive transducers ROBERT BOSCH GmbH 24 Nov 1972 [26 Nov 1971]  54303/72 Heading G1N In a rotary inductive transducer, a rotor 6 and a stator 21 are adjacently arranged, each being provided with at least one meander-shaped electrical conductor path each extending along the arc of a circle centred on the axis of rotation, the conductor path or paths of the rotor each forming a self-contained short circuit and being inductively coupled to an A.C. energized arcuate conductor path 22 on the stator, and the stator being arranged to supply amplitude-modulated voltages when the rotor rotates relative to the stator. As shown in Fig.1, the rotor consists of two self-contained conductor paths 3, 4. The outer path 4 has four times as many ribs as does the inner path 3. As shown in Fig.2, the stator consists of four meander-shaped conductor paths 11, 12, 13, 14. The paths 11, 12 have a configuration adapted to the configuration of the path 3, as do the paths 13, 14 to the path 4. The paths 13, 14 are staggered relative to one another by half a segment d signifying that the meander oscillations are shifted in phase by 90 degrees relative to each other. The paths 11, 12 are similarly staggered. Also arranged on the stator 21 is the arcuate conductor path 22 inductively coupled to the paths 3, 4. This path is in the form of a spiral and forms part of the resonant circuit of an oscillator 23. The path 22 is also galvanically coupled to the paths 11-14 at points 11'-14'. The paths 11-14 are respectively coupled to differential amplifiers 29, 30, 31, 32 via rectifiers G. Rectangular pulses appear at the outputs of the amplifiers when the rotor rotates. The out-of-phase arrangement of the paths 11,12 and 13, 14 results in the resolution of a rotary angle into a sine and a cosine component. An indication of the direction of rotation can be derived from the phase relationship. Counters may be connected to the amplifiers. In an alternative arrangement, Fig.3 (not  shown), the rotor comprises a single self-contained conductor path having an aperiodic meander arrangement which has a uniform linear frequency change. The stator has an identical conductor path and a single pulse is provided at each full revolution of the input system, namely when the paths of the two are in exact register. In a further alternative arrangement Fig.4 (not shown), the rotor comprises a pseudo-stochastic rectangular pulse train conductor configuration, a single pulse being provided at each full revolution if the stator comprises an identical conductor configuration. In further alternative arrangements, conductor paths having different form functions may be provided a plurality of times on one circumference. Also, stochastic character paths may be used.

The washing machine comprises a drum rotatable about a horizontal axis within a container mounted on springs and dampers in a cabinet. Wash, spin and timer motors A, B and TM are provided. Motor TM drives seven cams C 1 -C 5  (not shown) one step every two minutes and cams C 6 , C 7  (not shown) continuously at one revolution per minute. Cams (C 1 -C 5 ) control switches S 1 -S 5  having contacts 1-11 and cams (C 6 , C 7 ) operate switches S6, S7 in the circuits of the wash and spin motors A and B respectively. The wash motor A rotates the drum alternately in opposite directions at a low speed and spin motor B rotates it at high speed in one direction. A single two-speed motor may be used. The machine can only operate when the mains switch MS is closed and the door is closed to close door switch DS. The water level is selected by positioning switch S2 to select switch L or H according to whether a low or a high level for washing or rinsing is required and when contacts 1, 2 of switch S5 are closed the water valve E will be opened by the energization of winding W. When the selected level is reached switch L or H is moved to deenergize winding W and connect switches S1, S3, S4 in the circuit. Switch S1 can switch a thermostatically controlled switch T into series with motor TM so that, if switch T is open, motors TM and A are interrupted. Water heater D is controlled by switch S3. Spin motor B is controlled by switch S4 when switch S7 is open and switch EXT is closed and by switch S3 when switch S7 is closed and switch EXT is open. Switch EXT is operated by the user to introduce a short spin. The complete cycle comprises sixty steps, the first nine steps being a pre-wash after which the machine stops and the step at which the main wash is to start is selected. As shown, a selector knob is provided by which one of six programmes may be selected as marked on a circular dial but instead a linear scale with a pointer may be used. Switch S1 is operated at appropriate points to ensure that the appropriate water temperature has been reached.
