Abstract: Abstract of the disclosure A liquid dispensing device, e.g. for cosmetics, cleaning compositions or the like has a hand-operated pump which can be pumped a number of times without discharging any liquid from the device. Pumping charges a reservoir with the liquid and stores it under pressure, the liquid being discharged from the reservoir at will by actuating the pump to its full extent.

Abstract: ABSTRACT OF THE DISCLOSURE           An adjustable camera lens forms an image of an object on an image plane.  First and second mirrors produce respective first and second detection images of the object on respective first and second arrays of light sensors.  These arrays form portions of an integrated circuit chip.  Upon each actuation of the appara-tus to provide a focusing adjustment of the lens, a single pass scanning pass, and then arrests this scanning movement of the mirror until the apparatus is subsequently actuated again to initiate a subsequent scanning and focusing operation.  The scann-ing movement of the mirror moves the corresponding image on the corresponding array.  A signal processing circuit receives the outputs of the light sensors and produces an output signal which experiences a peak at that position of the moved mirror which causes the light distributions of the images to be in best corres-pondence on the arrays.  This mirror position is the correlation position and represents the existing object distance.  A cir-cuit which receives the output signal produces a mirror position signal which represents the mirror correlation position at which the output signal peak occurs.  A comparator compares the mirror position signal with a signal representing the lens position and allows a spring to move the lens independently of the mirror until the lens position signal corresponds to the mirror position signal.  At that time, the lens movement is arrested, leaving the lens in a focus position which corresponds to the mirror correlation position and to the existing object distance, and at which the image of the object is in focus on the image plane.

Abstract: ABSTRACT OF THE DISCLOSURE         An engine valve deactivator assembly comprising an elongated support member having one end adapted to be mounted on an engine and a slotted rocker arm slidably receiving said sup-port member and having an input means engaging portion and a valve engaging portion on opposite sides of said support member.          The rocker arm has a fulcrum member which is slidably mounted on the support member and is seated against the rocker arm on the side thereof adjacent the other end of the support member. The fulcrum member is controlled by hydraulic valve deactivating means having (1) an active condition in which the fulcrum mem-ber is held in a fixed position on the support member to cause the rocker arm to pivot about the fulcrum member in response to the transmission of reciprocating movement to the input means engaging portion to cause corresponding reciprocating movement of said valve engaging portion, and (2) an inactive condition in which the fulcrum member reciprocates on the support member and such that when the valve engaging portion is biased against movement the rocker arm pivots about said valve engaging por-tion in response to movement of the input means engaging por-tion such that the pivoting action of said rocker arm transmits no movement to said valve engaging portion.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved rotatable twist tube device is disclosed for false twist texturing a continuous filament thermoplastic yarn being passed through the twist tube.  The twist tube com-prises a hollow shaft rotor constituted as the rotor of an electric motor.  Two bell housings, one attached to each end of the motor body, house ball bearings which support the hollow shaft rotor near each of its ends.  A friction bushing is positioned in each end of the hollow shaft rotor.  The friction bushings each have a rounded front friction surface and have a back surface extending outwards from the hollow shaft rotor. The improvement comprises an annular extension of each bell housing which projects beyond the end of the hollow shaft rotor and encompasses a portion of the adjacent bushing.  The annular extension of each bell housing is adapted to prevent yarn wraps on the outside of the hollow shaft rotor by deflecting such wraps onto the surface of the friction bushing.

Abstract: ABSTRACT OF THE DISCLOSURE             An electronic kilowatt-hour meter having internal error correction is disclosed for metering electrical power and energy consumption in a single phase or polyphase electrical system.  A comparator compares an analog signal which is proportional to the voltage in the system with a relatively high frequency triangular waveform.  The output of the comparator which is a pulse width modulated signal having a pulse duration proportional to the amplitude of the voltage in the system is multiplied by a signal which is proportional to the current in a system.  The output of the multiplier is integrated to thereby provide a signal which is proportional to the energy consumed in the system.  The output of the integrator is converted to a pulse train having a frequency which is proportional to the amplitude of the output signal of the integrator, and hence is proportional to the kilowatt hours consumed in the electrical system.  In order to provides error correction, the phase of the analog signal which is proportional to the voltage in the system is shifted with respect to the phase of the triangular waveform by reversing the connections of these respective signals to the input terminals of the comparator.  This is done each time an output pulse is generated by the analog-to-pulse-rate converter.  Thus the integrator alternately integrates up and down to thereby correct any offset errors in the system.

Abstract: S P E C I F I C A T I O N                  RING LASER GYROSCOPE                 ABSTRACT OF THE DISCLOSURE           The invention is concerned with angular rate sensors, and particularly with ring laser gyroscopes which includes a device for compensating for the effects of temperature gradients and residual lock-in.  A ring laser gyroscope is provided which has a triangular block configuration, and which incorp-orates a triangular-shaped laser resonant cavity defined by three corner mirrors, including an output mirror.  The ring laser gyroscope of the invention includes an optical wedge and a prism attached to its output mirror which permit the center of support of the gyroscope to be located in the plane of symmetry of the block.  The gyroscope is mechanically vibrated about its center of gravity to prevent lock-in effects at low angular input rates.  The construction of the gyroscope reduces temperature gradients across the plane of symmetry of the instrument, which temperature gradients produce spurious output signals in the absence of an input angular rate.  The optical wedge and prism, together with an external corner cube retro-reflector, form an interferometer which provides compensation for the output signal of the gyroscope, enabling the gyroscope to produce an output free from the influence of the mechanical vibrations over a sub-stantial angle, and which permits large angle low frequency mechanical vibrations to be introduced to prevent lock-in effects, which large angle low frequency vibrations have no tendency to cause residual lock-in effects to occur which produce non-linearities in the scale factor of the laser.
