Abstract: ABSTRACT OF THE DISCLOSURE          A volume control apparatus wherein a master volume control resistor is controlled by a motor and a control circuit is provided for the motor which includes a presettable-variable resistor and a slave-variable resistor which is driven by the output shaft of the motor.  A first comparator is connected to the presettable-variable resistor and to the slave-variable resistor which are in turn connected across suitable supply voltages and depending upon the relative voltages across these resistors a motor control discriminator circuit operates the motor in either the clockwise  or counterclockwise direction to vary the master volume control and the slave-variable resistor until the slave-variable resistor is substantially equal to the presettable-variable resistor.  When the resistance of the slave-variable resistor approaches the presettable-variable resistor the output of the master volume control is connected to an output speaker by a relay circuit.

Abstract: Abstract An illumination and pickup device including a lucite head with an elliposidally shaped wall that is covered with reflective paint.  An input source of light is positioned at a first focal line of the ellipsoidal head and the emitted radiation is internally reflected to form an intense slit image at the second focal line of the head.  A circularly shaped cylindrical exit por-tion having its axis at the second focal line is cut at the emitting end of the ellipsoidal head.  A flat surface positioned adjacent to the circularly shaped cylindrical portion and in the plane of the second focal line abuts an irradiated surface and thereby defines an alignment position for the ellipsoidal head.  Optical fibers are affixed adjacent the cylindrical cut-out portion to receive the light that is reflected from the irradiated surface and to carry the light to a photodetector.

Title: Thread cutting mechanism for sewing  machines

IPC: D05B37/06

Granted: 1983-03-01
Abstract: ABSTRACT A knife arrangement for cutting devices on sewing machines, has a fixed knife, and a movable knife arranged upon a driven holder.  The movable knife is pivotally mounted in the holder by means of an arm which is angled from the blade at a distance from the cutting edge, the movable knife being lightly pivoted towards the fixed knife by means of a spring. Thus the contact pressure between the knives is normally relatively low and wear is correspondingly reduced.  When a thread or stitch to be cut is placed between the knives, the reaction force from the cutting action causes the movable knife to pivot towards the fixed knife.  Thus increased contact pressure between the knives arises only during actual cutting.

Abstract: NEGATIVE RATE COMPENSATED HYDRAULIC SERVO SYSTEM      ABSTRACT     A flapper valve having a negative rate character-istic is variably opened by an external force and controls fluid pressure to a piston which moves, in response to this pressure, in order to return the valve to a null position.  A positive rate flapper valve applies force to the negative rate flapper valve and balances the fluid pressure in the negative rate flapper valve, thus providing high sensitivity negative flapper valve operation in the null position region and a negative rate in the region to overcome piston friction, without instability.

Abstract: Abstract A process for producing improved auto-crosslinking binders is described. The binders are based on amine modified epoxy compounds and are obtained through reaction of epoxy compounds  with secon-dary amines, preferably alkanol amines, and monocarboxylic acids. Optionally the hydroxy groups of the reaction product are reacted partially or totally with an ?,B-unsaturated monoisocyanate. The binders have a double bond number of at least 0.5, preferably 0.8 to 2.5?,B-positioned double bonds, and are rendered water soluble through neutralisation with acids. Thereafter, they have an amine number of between 0.8 to 3Ø The binders are excellent vehicles for coating compositions applied by cathodic electrodeposition.

Abstract: Abstract of the Disclosure In a catalytic converter, a sheet metal housing encloses a pair of sheet metal catalyst pellet beds each having an inner bed member and an outer bed member with the inner bed members having mating peripheral flanges and also forming a plenum between the beds whose air space is maintained by contacting louvers which form the air passage between the beds.  A shoulder is formed integral with and extends across each of the outer bed members and is held engaged on its inner bed side with the flange on one of the inner bed members by an extension on the other inner bed member which is sandwiched between the outer bed members while the remaining portions of the mating flanges are received between flanges on the outer bed members.  The inner bed members thus cooperate with the outer bed members to completely separate the pellets in the beds while relative expansion with heat is permitted between the inner bed members and the outer bed members and also between the inner bed members and the housing members and while narrowing of the air plenum is positively prevented by the louvers on the inner bed members.

Abstract: Abstract of the Disclosure DC control signals responsive to ACC voltages are applied to a color signal amplifier, to which recording and reproducing color signals are applied, to control the operation of the color signal amplifier to recording or reproducing mode. Such control is attained by using color killer signal responsive to mode changeover and ACC detector signals which serve to assign the color signal amplifier to recording or reproducing mode.          Color signals are obtained from the output terminal of the color signal amplifier in both modes.  In the case of recording mode, essentially undesirable recording color signals appearing to the output terminal of the color signal amplifier are by-passed by a low-pass filter, and only ACC detector voltages which are used as color killer signals are supplied to a mixer circuit which mixes brightness and color signals to generate composite color signals to be recorded.  This recording signal mixer circuit serves to restrain, if necessary, low frequency converted color signals from being supplied from the recording signal mixer circuit to a recording head responsive to color killer signals.  In the case of reproducing mode, color signals appearing to the output terminal of the color signal amplifier are supplied to a reproducing mixer which composes composite color signals to be reproduced from brightness and color signals to be reproduced.  Input signals to the color signal amplifier are treated at the time of recording mode in such a way that color killer voltages are superposed on essentially undesirable recording color signals to extract only color killer voltages on the output terminal side of the color amplifier, thus allowing the circuit, which functions as the color amplifier at the time of reproducing mode, to serve as the circuit for treating color killer signals at the time of recording mode, or making the function of the single circuit different in reproducing and recording modes,
