Abstract: NOISE-NEUTRALIZING DIGITAL INTERFACE CIRCUIT     ABSTRACT OF THE DISCLOSURE     An interface circuit for facilitating the reception of bus-transmitted digital signals in the presence of electrical noise includes transmitter means adapted to be coupled to a communication bus.  The transmitter means has a controllable switch means for generating digital output signals to be transmitted to the bus and receiving means coupled to the transmitter means for receiving digital input signals which define a first wave form and are transitory between a first voltage and a second voltage. The receiving means includes first conditioning means for shaping the first wave form to a second wave form and means for providing a first output condition when said second wave form transcends through a first intermediate voltage in a first transition direction and for providing a second output condition when said second wave form transcends through a second intermediate voltage in a second transition direction.  The interface circuit thereby neutralizes spurious electrical signals of a first type having a maximum amplitude less than the difference between the intermediate voltages.

Abstract: CONVEYOR LUBRICATION APPARATUS                   ABSTRACT OF THE DISCLOSURE          A conveyor lubrication apparatus includes a counter for energizing lubrication devices once for each predeter-mined number of cycles of the conveyor past a lubrication station.  Timers energized by the counter activate control valves for a predetermined period of time to supply lubri-cant to each element of the conveyor as each element of the conveyor reaches the lubrication station.  A current sense circuit detects current flow to the control valves and energizes the central lubricant supply pump to pressurize the lubricant flow lines for a predetermined period of time, at the end of which the pump is de-energized until the next control valve is energized.  A pressure sensor is disposed in the lubricant flow lines to detect a low pressure level and causes the pump to be de-energized and an alarm to be activated.

Abstract: Abstract There is disclosed a system for regulating the speed of an autonomous hydraulic turbine, driving a constant frequency AC alternator. It uses electri-cal resistors as a control load so that the turbine water flow remains constant. There is a quartz clock producing a reference frequency, which is compared with the alternator frequency, using a shift register. This shift register transforms the frequency differences into an analog signal. The output  of this register passes via a filter chain and a PID circuit to an analog-digital converter, to be transformed into digital bits, to be optical-linked to the triacs switching the braking load. For a given number of bits, a high number of switching possibilities of -the control loads exist, assuring a rapid control of the alternator frequency. Waterhammer conditions in the penstock are thus also avoided. The control loads are activated after the first cross-over of the alternator voltage to avoid harmonics of the basic alternator frequency.

Abstract: ABSTRACT         The device 2 described and intended for applying cosmetic compositions comprises a sleeve 1 within which there is a column of cosmetic composition adapted to be raised by a lifting mechanism.  The delivery end of the sleeve is occluded by a head part 4 which carries over at least a part of its surface an applicator material 7 for holding and subsequently applying the cosmetic composition and which is provided with outlet orifices 5', 5" through which the cosmetic composition can emerge from the sleeve and pass to the applicator material.  In consequence, when the lifting mechanism is actuated, the cosmetic composition passes into the applicator material in a measurable quantity and is avail-able there for subsequent application.  The applicator material may be a covering of fiber material or foam material which is permeable in respect of the cosmetic composition and which wholly or partly covers the head part, but it may also be a covering of flocking or brush hairs which wholly or partially covers the head part.  The outer contours of the applicator material are determined by the outer contours of the head part and may prefer-ably comprise both slightly convex to flat zones and also zones with an outwardly shaped point or edge.  In this way, the cosmetic composition can, with the same device and without any additional aids, be applied flat or in linear form as desired without the outer contours changing during use.  The device is suitable for all types of cosmetic compositions, i.e. both for hard compositions (e.g. eyebrow pencils) and also for pasty-wax-like compositions (e.g. lipsticks) and for creamy-soft compositions (e.g. rouge, eye shadow).  The location, size and configuration of the outlet orifices in the head part can be adapted to particular require-ments, although it must be borne in mind in the case of hard compositions that the maximum radial distance A between the outlet orifices and the sleeve axis ought not to be less than the radius of the column of cosmetic composition.  Furthermore, for hard compositions the inside edges of the outlet orifices should expediently be constructed as scrapers.     Fig. 1
