Filed: 1984-12-19
Abstract: A magnetic head is provided having a core of a soft-magnetic material with a comparatively low saturation magnetization and layers of a soft-magnetic material having a higher saturation magnetization than the material of the core on the gap-bounding faces. In order to avoid the detrimental effects of the non-magnetic transition zones between the material of the core and the layers of soft-magnetic material, which transition zones as it were form subsidiary gaps, the layers of soft-magnetic material on the gap-bounding faces have different thicknesses.

Abstract: Absorbance or transmittance properties of a plurality of quantitatively analysed representative sample solutions are measured. One of the representative samples is selected as a standard sample and, from the absorbance or transmittance properties, values representing known differences between both hue and brightness of the standard sample and each other representative sample are derived. Absorbance or transmittance properties of a sample dyestuff solution to be tested are then measured and respective values representing the respective differences between both the hue and brightness of the tested sample and the standard sample are derived and compared with the previously derived values representing the known said differences to thereby measure the color difference. 
     Dyeings of the representative samples of known color and hue may be made and the color and hue of the resulting dyeings measured so that by determining the abovemen- tioned differences of color and hue for a given sample to be tested the color and hue of a dyeing thereof may be accurately predicted.

Abstract: A rotary-vane type fluid machine is constructed such that a rotor (1) is caused to rotate within a casing (2) to increase or decrease the volume of a space created between the outer periphery of the rotor (1) and the inner wall surface of the casing (2) by vane structures (8) which rotate together with the rotor (1) to thereby transfer a fluid by pressure in accordance with the variation in volume of said space. The vane structure (8) has two vanes disposed in substantially symmetrical relationship with respect to a shaft (6) of the rotor and fixed so that they can not moved relative to each other. The fluid machine also comprises a crank mechanism (3, 4, 3a, 4a) which causes the vane structure (8) to radially advance the retreat in order to reciprocally vary a distance between a center of the shaft (6) and a tip end (7) of one vane and a distance between the center of the shaft (6) and a tip end (7) of the other vane in accordance with the rotation of the rotor (1).

Abstract: A machine levelling pad with damping properties is disclosed, wherein a first support member (44, 75, 92, 17b) having a damping cavity (45, 75a, 91,109) is located on a base (29), and a second support member (56, 78, 93, 112) having an outer surface (57, 94) cooperatively shaped to the damping cavity is disposed within the damping cavity so as to create a peripheral boundary space (58, 69, 79, 95, 120) between the first and second support members. Spring means (54, 81, 98, 114) is provided to support the second support member (56, 78, 93, 112) relative to the first support member (44, 75, 92, 17b) in a direction substantially parallel to the longitudinal axis of the boundary space (58, 69, 79, 95, 120). A machine member (11, 17, 35) is located on the second support member (56, 78, 93,112), and, in one embodiment, a viscous damping material is provided to substantially fill the boundary space (58, 69, 79, 95, 120) between the first and second support members. In operation, the spring means (54, 81, 98,114) and damping medium are compliant in several directions to permit relative movement between the first and second support members. Thus, when the spring means (54, 81, 98, 114) is oriented in a vertical direction to carry the weight of a machine member, the machine is allowed to move with the second support member in a horizontal, unloaded, direction thereby causing the first and second support members and damping medium in the boundary space to undergo squeeze-film damping, effecting an increase in the overall dynamic stiffness of the machine. 
     Another embodiment employs a visco-elastic medium in the damping cavity (58, 69, 79, 95, 120) to effect damping.

Abstract: In order to solve the interlocking task in devices for panel-interlocking in the switchboard panels of a switchboard plant, information is required on the states (switching states, earthing etc.) of the other parts of the plant. These states can be detected in a model of the plant and can be interrogated from there. The invention proposes that, as a model, each busbar system (SSI, SSII) of the switchboard plant be provided with a bus system (BI, BII) on which the states of all the switchboard panels (SF) are imprinted and from which the required information on states can be interrogated by panel interlocks (FV).

Abstract: water-swellable clay composition, comprises a water-swellable clay, particularly a montmorillonite clay, such as bentonite; xanthan gum; and one or more additional water-soluble gums, for example, guar, dextran, acacia or locust bean. The xanthan gum together with one or more additional water-soluble gums prevents the montmorillonite clay from substantial coagulation or flocculation upon contact with salt contaminated water even in high concentrations of, for example, 15-40% by weight salt. Xanthan gum is an amount of 0.1-20% based on the weight of the water-swellable clay, in the composition together with one other water-soluble gum, for example guar gum, dextran gum, acacia gum and/or locust bean gum in an amount of 1.0-10% based on the weight of bentonite in the composition, will provide a clay composition capable of excellent stability without component separation in salt contaminated water. The composition is particularly useful as an additive to compositions used as stable drilling fluids in rotary drilling, and as lagoon and landfill sealants.

Abstract: a A narrow bandwidth analog-to-digital conversion (ADC) system is described in the context of the color burst processing and burst phase detecting circuitry of a digital color television receiver. The ADC (14) includes a dither generator which adds a dither signal to either the analog input signal (10) or to the reference signal (38) used by the ADC. This dither signal increases in magnitude by 1/16 of an LSB value at a rate one-quarter of the burst frequency and changes in sign at one-half of the burst frequency. This signal passes through a low-pass filter (18) in the chrominance channel providing an increase in sample resolution by averaging the samples in a chroma band-pass filter and in the phase detecting circuitry (30).
