IPC: F16N13/16
Filed: 1988-06-16
Abstract: A hand press for supplying pasty products has an ejection line (23), at the front end of a main body, in which a pressure piston is arranged so as to be movable in a reciprocating manner, which pressure piston is connected to a piston assembly which can move in a stepped cylinder inside the main body. The front section of the cylinder has a smaller cross-section than the rear section. The piston assembly includes front pistons and a rear piston which can move axially in the cylinder and split this cylinder into a centre air inlet chamber (11), into which a connecting line (41) from a compressed-air inlet valve (20) opens, a rear pressure chamber (12) and a front air outlet chamber (10). The rear piston has flow openings (16), and the pressure chamber (12) is connected via a hollow centre part (15) of the piston assembly and radial holes (14) constructed in the centre part to the front outlet chamber (10), which has an air outlet opening (13) to the atmosphere. On the rear piston there is arranged a valve assembly, having an inner (24) and an outer (25) sealing disc, which are connected to one another and can be moved in the axial direction with respect to the rear piston between a first operating position, in which the outer sealing disc (25) seals the hollow centre part (15), and a second operating position, in which the inner sealing disc (24) seals the flow openings (16). First and second stop buffers (17) and (18) respectively engage with the sealing discs (24, 25) in the limit positions of the piston assembly, and move the said sealing discs in the axial direction between the first and second operating position. <IMAGE>

Abstract: The instrument measures directly the phase jitter of analog signals emitted on the line by the device under test, when even clock information is not available and when particular specifications and limitations do not allow the use of analog instruments. It uses a circuit which generates a square-wave clock signal with the same phase and frequency characteristics as the signal to be measured, so that a phase comparison with a reference signal can be made. Error signal obtained is filtered, measured and displayed.

Abstract: A reflectance photometer for quantitatively measuring diffuse light includes a light source located above a sample. The reflectance photometer also includes a first detector mounted at a preselected scattering angle relative to an axis extending perpendicularly from the sample through the light source. A first linear polarizer is mounted between the sample and the light source. The direction of polarization of the first linear polarizer is vertical to a scattering plane defined by the direction of incoming light from the light source and the direction of reflected light detected by the first detector. A second linear polarizer is mounted between the sample and the first detector. The direction of the second polarizer is parallel to the scattering plane. The reflectance photometer can include a second detector mounted at a second, scattering angle. A third linear polarizer is mounted between the sample and the second detector. The direction of polarization of the third linear polarizer can be perpendicular or parallel to the scattering plane. Generally, the three polarizers are close such that the contributions of scattered light as related to surface noise will be minimized for the first detector and maximized for the second detector, respectively. The optimum settings of the polarizers will depend on the settings of the polarizors, the scattering geometry, the sample orientation and the bulk and surface scattering properties of the sample material.

Abstract: In an automatic gain control (AGC) network in a video signal processing system, a comparator (70) responds to an input control signal for providing an output control signal to an RF tuner (23) amplifier for decreasing its gain below a normal maximum level when the input signal exceeds a threshold value. The operation of the comparator is inhibited beyond a predetermined level of the input control signal, to prevent a false output gain control signal from being developed. The input control signal is applied to the comparator (70) through transistor (84). As the input control signal falls beyond the predetermined level, the comparator (70) input is prevented from falling by inhibiting clamp transistor (90).
