Abstract: ABSTRACT OF THE INVENTION         A generally-H shaped knob spring is provided which comprises two flat members joined by a center bowed member.  The spring is received in an undercut slot adjacent one side of a recess in a knob for receiving the end of a shaft, the bowed portion extending into the recess.  When the shaft is inserted in the recess, the bowed portion of the spring is flattened out causing the end strips to be bent to bite into the surface of the slot and the surface of the shaft adjacent the slot wherein the spring releasably grips the knob and the shaft to hold the knob securely on the shaft so that. it does not wobble or twist thereon.

Abstract: PARTIAL PLANARIZATION OF ELECTRICALLY    INSULATIVE FILMS BY RESPUTTERING                 Abstract of Disclosure A method of partially planarizing an electrically insulative layer over an integrated circuit substrate which has a raised line metallization pattern having narrower lines and wider lines. The insulative layer has narrower and wider elevations corresponding to the underlying lines.  Resputtering of said insulative layer is conducted for an amount of time sufficient to planarize the narrower elevations in the layer but insufficient to so planarize its wider elevations.          This method is useful in planarizing insulative layer elevations through which via holes are to be formed, particularly via holes which are wider than the under-lying metallizing lines which they contact.  Such a planarization method in via hole formation avoids the tunneling effects which would otherwise result from the over-chemical etching necessary to form the via holes.

Abstract: ABSTRACT OF THE DISCLOSURE    In a motor-driving system, the motor speed is con-trolled by a feedback signal derived from the difference in frequency and phase between a manually adjustable variable frequency and a rotational speed indicating signal.  Frequency deviation of the manually adjustable frequency from a standard frequency is detected to energize a visual indicating device to indicate the magnitude of the frequency deviation and hence the motor speed deviation from a setting level.  The direction of the frequency deviation is detected to indicate whether the motor speed deviation is above or below the setting level.  The variable frequency is manually adjusted to vary the motor speed by noting the visual indication until null indication is obtained.

Abstract: ABSTRACT OF THE INVENTION      Printed circuits are fabricated by a process which employs initial chemical deposition  of copper on a predrilled substrate followed by electroplating build-up of conductors to desired pattern. The conductors are then passivated by thinly plating them with a mechanically durable, chemically passive metal.           To provide solder compatibility in areas where connections are to be made to the printed circuits, a plating of tin/lead is applied in those areas while masking all other areas to eliminate plating. The remaining exposed copper is then etched away. An insulating solder mask is then applied.

Abstract: Abstract of the Disclosure:           Water-soluble copper, cobalt and chromium complex monoazo compounds of which the metal-free monoazo compound contains as diazo component an aminophenol or aminonaphthol compound substituted by a fiber-reactive radical of the vinyl sulfone series, the aminophenol possibly being substituted by a lower alkyl, lower alkoxy, nitro, sulfonic acid group, or a chlorine or bromine atom and the naphthol possibly being substituted by a sulfo group, and as coupling component a 6-sulfonaphthol (8) which may be substituted by a sulfo group in the adjacent aromatic nucleus and must be substituted by the monoamide radical of succinic acid, glutaric acid or adipic acid.   They are prepared by diazotization of the corresponding aniline and naphthylamine compounds containing, in o-position to the amino group, a hydrogen atom, a hydroxy group or a lower alkoxy group, with subsequent coupling with the above coupling component and transformation into the metal complex compounds by an agent donating copper, cobalt or chromium, optionally in the presence of an oxidant.  The coupling components can be prepared by reacting the corresponding aminonaphthol mono-or disulfonic acids with a dihalide or anhydride of succinic acid, glutaric acid or adipic acid.      The metal complex compounds have outstanding dyestuff - 1a -properties.  They have a good solubility in water and are es-pecially suitable for dyeing fiber materials of natural and regenerated cellulose, of natural, regenerated or synthetic polyamides or polyurethanes as well as leather.  The dyeings display very good fastness to light and to wet processing, a high color strength and portions of the dyestuff which have not been fixed on the fiber can be washed off easily.

An alarm circuit indicates a tempera-ture error or a power failure in the thermostat at the thermostat and at a remote location.  This circuit utilizes an alternating current source which activates current direction-dependent indicators operating on alternate half cycles.  electrical isolation of the temperature monitoring circuitry from the circuitry controlling heating, cooling and fan equipments is provided by coupling a signal indicating a temperature error through a single electrically isolating interface to equipment selection and control circuitry at line potential.

Abstract: ABSTRACT OF THE DISCLOSURE         In a closed circulation system containing a constant amount of liquid, a force is generated for driving the liquid through the system.  A branch line extends from the circulation line of the system at a point adjacent to and closely down-stream from the location at which the force generating cir-culation is effected.  A collecting chamber is provided in the branch line spaced from the circulation line.  Gases dis-solved in the liquid are released at the location of the force generation and the gases are removed through the branch line and the collecting chamber.  Downstream from the branch line the liquid is either cooled or returned at least to normal pressure for its continued circulation so that it is able to absorb air from the air accumulations within the system with which the liquid comes into contact.

Abstract: FLOW RESPONSIVE DEVICE                        ABSTRACT           A flow responsive device for use in a fluid flow system to establish a signal when a predetermined flow rate is attained within a flow conduit.  The device is adapted for connection to a flow conduit and has a target vane adapted for insertion within the flow conduit for movement in response to predetermined flow to open internal valve means against the bias force of a compres-sion spring and control pressure within a pressure chamber. In operation, the control pressure is maintained at a higher pressure than the fluid pressure within the flow conduit so that after initial opening of the valve means, the control pressure drops and the valve means undergoes fast-action movement to its fully open condition.  The flow rate at which the valve means closes is less than the flow rate at which the valve means opens so that hunting of the valve means during operation is prevented. The pressure chamber may be connected to a control line having a flow restrictor therein so that when the valve means is opened, a pressure drop across the flow restrictor establishes a signal which may be employed to control external equipment.

The whole structure of the container is ultrasoni-cally scanned initially using piezo electric transducers  to obtain an output from which is derived a distinctive identity for the container, determined by the particular characteristics of the internal structure of at least a portion of the con-tainer, and also a reference signal indicative of the whole container structure when its integrity is intact.  Subsequent ultrasonic scanning of the whole container structure, for example intermittently, produces a matter signal which if different to the reference signal indicates the occurrence of a breach in the container's integrity.  The distinctive identity for the container may be derived from a distinctive internal structure of the cover which preferably contains a material matrix, e.g. aluminium, having inclusions of, for example, tungsten, embedded therein in a random configuration.
