Abstract: Abstract The present invention comprises an amplifier circuit and transformer based power supply wherein greater efficiency is achieved by using the input signal characteristics to control various aspects of the circuit operation.  The transformer primary winding is energized by a pulsed power supply which is duty cycle modulated in response to the signal being amplified. One embodiment of the amplifier employs output transistors connected to respective stepped voltage levels.  Amplifier con-trol circuitry acts in relation to the input signal amplitude to more evenly distribute the voltage drop across the inter-connected transistors, thus reducing amplifier power requirements and minimizing distortion in the amplifier output.  In another embodiment, a stereo amplifier constructed in accordance with the present invention contains a network for inverting the audio signals received by a first amplifier input channel.  The inverted signals are thereafter processed in out-of-phase relationship to the signals in the second amplifier input channel to more efficiently utilize the power supply.  In yet another embodiment, the power supply itself is constructed with a number of fault detecting circuits which sense fault conditions in either the power supply or the amplifier and shut the power off accordingly.

Abstract: METHOD AND DEVICE FOR DETECTING LEAKS FROM PIPELINES       ABSTRACT OF THE DISCLOSURE         To detect leaks from pipelines carrying fluids, especially oil, light is transmitted through a fibre - optic held in proximity with the pipeline.  The fibre-optic is surrounded by a medium of which the refractive index is altered by the influence of the leaked fluid.  In a preferred embodiment the medium is a silicone rubber (4) of which the refractive index is normally lower than that of a quartz fibre optic (3), but of which the index increases to that of the quartz or above when oil (7) soaks into it through a permeable cladding (1) and elastomeric protective layer (2), thus rendering the fibre optic non-internally - reflective so that light (6) is absorbed.  Control means linked to a light receiver detect that change and the position of the leak is located to within the length of the optic.           In another embodiment the medium is a liquid which is expelled from around the optic by the action of leaked fluid.                                                    [Fig. 2]

Abstract: Abstract of the disclosure The invention contemplates a multi-focal spectacle lens with a dioptricpower varying progressively between different zones of vision (progres-sive lens). The principal sight line, i.e. the line connecting the pene-tration points of the lines of sight for different object distances is a curve swung toward the nose of the wearer. In order to enable a pleasing binocular viewing for the spectacle wearer the progressive surface of the lens is horizontal symmetric with respect to said principal sight line. The progressive zone lying between the far-vision zone and the near-vision zone of the lens is short and within this zone astigmatism exists along the principal sight line within the scope of a permissible reduction in vision. Within the progressive zone and the near-vision zone the distortion caused by the prismatic powers at points of the nasal region and temporal region which correspond to each other is so selected that the horizontal and vertical directional errors do not exceed tolerable values. In this way the wearer will see an equally sharp or an equally blurred image of the object with both eyes while binocularly non-harmonizing directions of sight are avoided so that the fusion of the eyes is convenient for each object distance.

Abstract: CONTROL FOR HYDROSTATIC TRANSMISSION               ABSTRACT OF THE DISCLOSURE         A control for a hydrostatic transmission having selectable positions for controlling the flow of fluid to achieve forward, reverse and neutral positions and to govern output speed, which control includes a control member operably connected to the transmission, an actuator, such as a foot pedal assembly, mounted for movement between reverse, and neutral positions, and a pivotal crank including a first leg connected to the actuator, a second leg connected to the control member, an intermediate third leg having a tab on the outer end thereof.  The control member is urged towards a neutral position by a pair of arms mounted at one end coaxially with the bell crank and having outer free ends disposed on opposite sides of the tab on the third arm of the bell crank, and a spring interconnecting the free ends of the arms and biasing them towards each other and into engagement with the tab. One arm engages a stationary stop at a location corresponding to the neutral position as the bell crank and the other arm is pivoted in one direction from the neutral position in response to movement of the actuator. This causes the spring to be stretched and the spring subsequently returns the bell crank to the neutral position when the actuator is released. The arms operate in the reverse fashion when the bell crank is pivoted in the opposite direction from neutral.       The foot pedal includes a pedal support mounted for pivotal movement in opposite directions from the neutral position and a foot pedal mounted on the pedal support for pivotal movement between raised and depressed positions.  A latch assembly for releasably locking the pedal assembly in the neutral position is released by depressing the foot pedal.

Abstract: ABSTRACT OF THE DISCLOSURE         An electro-acoustic transducer using thin, light-weight, planar diaphragms driven by strategically located, coil driven, high-energy, permanent magnels.  A framework maintains the diaphragms in substantially co-planar relationship a predetermined distance from and parallel to a rear support wall.  The diaphragms include at least one hinged woofer diaphragm and a foam-supported tweeter diaphragm.  The small, high energy movable permanent magnets are attached to the rear surface of each movable diaphragm.  Cooperating with each movable magnet is a respective, stationary electromagnetic coil with a cross-over network directing the incoming signal to the appro-priate coils, thereby placing the magnets and attached diaphragms into cooperating fore and aft motion.  The frontal acoustical waves produced by each woofer con-structively interfere to augment low frequency response. The tweeter construction provides wide frontal dispersion of high frequency acoustical waves.  Woofer backwaves are attenuated before emerging along the rear support wall and the tweeter backwave is vented into a rear isolative chamber.
