Abstract: Process and machine for producing pressed vibrated concrete blocks, providing for a suitable vertical displacement of the counter mould (3) in its block delivery step, whereby the blocks are delicately laid on the ground. The process comprises the steps of filling the moulds (1), lowering the counter mould (3), pressing and vibrating the concrete, opening the bottom of the mould (1) by removing the bottom plate (5), causing the moulded blocks (M) to be deposited on the ground (S) by lowering the counter mould (3) and lifting the mould (1). The machine is characterized by provisional limit stop means (18-20) so that the counter mould (3) can be lowered for pressing the concrete and during an extra stroke for putting the blocks (M') on the ground (S).

Abstract: A computer controlled exercise machine in which the user selects an exercise mode and its profile by programming the computer. Signals are produced by the program to control a resistive force producing device. Sensors produce data signals corresponding to the force applied to the actuating member of the system, velocity of movement and angular position which are continuously sampled at a high rate by a microprocessor operating under control of the program. The sampled data values are used to update and display performance results for the exercise and to compute the values of other parameters and, in some exercise modes, to control the amount of the resistive force.

Abstract: A modular connector for field termination of an electrical cable containing a plurality of individually insulated conductors and having a body, a contact carrier in snap-in assembly with the body and a cover assembly for snap-in assembly with the body in the field and including a cover and a cable strain relief member attached to the cover by a living hinge. The cable strain relief member is arranged for snap-in assembly with the body in the field. A stuffing member carried by the cover sets each conductor in an associated contact of IDC type mounted on the contact carrier as the cover is snapped into assembly with the body. A blade mounting on the contact carrier cooperates with a shearing member depending from the cover to trim the free ends of the conductor during cover assembly. Assembly of the cover with the body also applies strain relief to the cable and each of the conductors and also deflects the trimmed conductors away from the shearing blade.

Abstract: A process has been developed for effectively purifying compressed air by removing water vapor, carbon dioxide and other impurities through the use of gas separation membranes systems. Gas separation membranes have been found which are capable of purifying air to a suitable level for operation of analytical instrumentation apparatus such as Fourier Transform Infrared analyti­cal spectrometers and related instrumentation equip­ment. Impurities normally found in compressed air used in operation and purging of instrumentation devices include water vapor and CO₂, which are strong absorbers of infrared radiation at wavelengths which interfere with analytical wavelengths and spectral regions commonly employed for analysis of a variety of organic and inorganic materials.

This by-pass conduit (104) may be connected to a feed water tank (74). At very low load and in the case of a gas turbine trip, the neces­sary water flow for cooling the walls (14) of the combuustor (12) may exceed the demand of feed water to the evaporator (66). Under these operating conditions feed water may be drained off ahead of the evaporator (66) through said by-­pass conduit (104).

Abstract: A dampener for a lithographic press comprises a form roller (20b), a metering roller (22b), a reservoir of dampening solution lying above and between the form and metering rollers (20b,22b), and means for supplying solution to the reservoir. The amount of solution applied to the form roller (20b) can be controlled by adjusting the pressure between the form and metering rollers (20b,22b) without appreciably affecting the pressure between the form roller (20b) and the plate cylinder (10b). Excess moisture retained on the form roller (20b) and excess solution which collects between the plate cylinder (10b) and the form roller (20b) is continuously returned directly to the reservoir. The metering roller (22b) and the plate cylinder (10b) are driven by the press gear drive system, and the form roller (20b) is driven from frictional contact with the plate cylinder (10b) and the metering roller (22b), to aid in retrofitting the dampener to existing presses.

Abstract: A safety circuit (12) for the surveillance of the proper functioning of an electronic wheel lockup-protected motor vehicle brake system includes automatic control circuits (10, 38), automatically controlled magnet valves (4, 46), and pick-up transducers (3, 47) at the motor vehicle wheels (2, 48) to be monitored. An error message and/or a partial shut-off of a defective pair of circuits, relating to wheel lockup protection circuits relating to diagonally disposed wheels, occurs in this safety circuit when an upward jump or a downward jump is recognized in the measured velocity of the one wheel and, simultaneously, the speed of the diagonally, oppositely disposed wheel or of any other wheel is measured to be above a limiting value. It is thereby avoided that an undesired error message occurs already when a jump in velocity is recognized, for instance in case of a standing vehicle, in case of a starting of the motor, or in case of a beginning of rolling of the vehicle.

Abstract: Automatically reconfiguring an electronic landing display that includes a flight path vector (FPV) symbol and a rising runway symbol combined with a digital altitude value that merge at low aircraft altitudes is disclosed. During approach, when the aircraft descends below a predetermined minimum altitude, e.g., 200 feet, the FPV symbol is removed. When the aircraft is on the ground and during takeoff, the rising runway symbol is removed. Removing one or the other of the merging symbols prevents the symbols from overlapping. Thus, the potential for pilot error due to one of the merging symbols occluding the other is avoided.

Abstract: A recording mode identifying circuit (12) is provided for use in a magnetic recording and/or reproducing apparatus capable of recording a colour video signal in a first or low-band mode in which a luminance signal is recorded as a frequency modulation of a first carrier frequency and a second or high-band mode in which the luminance signal is recorded as a frequency modulation of a second carrier frequency. For avoiding erroneous identification of the mode with which the colour video signal was recorded, a predetermined frequency component of a reproduced FM luminance signal which corresponds to the frequency of the carrier of one of the modes when modulated by a predetermined luminance signal level, for example, the frequency component of the lower sideband corresponding to the sync tip level in the low-band mode, is phase inverted (23) and an amplitude component of the resulting signal with phase inversion is eliminated (31) and the mode with which the reproduced colour video signal was recorded is determined by detecting (26) the level of the predetermined frequency component, for example, corresponding to the sync tip level in the low-­band mode.

Abstract: A tracking control robot controls its arm end, which holds a tool, to track a taught path so that a reaction force between a workpiece and the tool remains constant. An ideal state for the arm end is determined from the present state of the arm end and the difference between the actual reaction force and a predetermined target force. Then, this ideal state is compared with a reference state of the arm end on the taught path to obtain a target position and a target attitude of the arm end. Since a target position is always determined independently of the last target position, no position error due to time delay affects a new target position even when the next target position is genefated before the tool reaches the last target position. Thus, the robot is quick, responsive, and accurate when tracking at a constant operation speed.
