Title: Method and apparatus for enciphering and deciphering audio information
IPC: H04K1/04
Filed: 1977-05-17
Abstract: A method of, and apparatus for, enciphering and deciphering audio information which is subdivided into partial blocks along a time axis, the partial blocks being mutually interchangeable according to key information. The incoming analog audio signals are subdivided into a number of frequency bands, each of which is assigned to an information channel. The analog audio signals of each information channel are converted into digital signals which are subdivided into main blocks along the time axis. The main blocks of equal time of each information channel are subdivided into sub-sections of the same magnitude with respect to time and which are interchanged, in accordance with the key information with sub-sections of the same main block or with sub-sections of a time-equal (i.e. isochronal) main block of another information channel. After the interchange in each information channel, the digital signals are converted into analog signals and the interchanged sub-sections are group together into new main blocks, in order to render possible a further processing of the time-equal or isochronal new main blocks of each information channel.

Title: Yarn feeder
IPC: B65H51/22
Filed: 1981-02-03
Abstract: A storage drum (9) receiving a plurality of turns serves for the intermediate storage of yarn to be fed to a machine. A yarn-feed device has a plurality of axially attached elements (8), on which are mounted yarn-displacing members (10) which, during the rotation of the drum, are moved to and fro in the longitudinal direction by a control cam, in order to displace the yarn turns towards the yarn draw-off point.

Patent ES-8300594-A1 (ES)
Title: Pressure control arrangement for vehicle braking system with antiskid control equipment
IPC: B60T8/94
Filed: 1981-10-27
Abstract: An antiskid control arrangement of a hydraulic vehicle braking system includes a master cylinder device and a throttling valve device arranged between the master cylinder device and the brake pedal. The throttling valve device is incorporated in a circulating circuit which includes a hydraulic pump operated exclusively during antiskid control operation. During normal braking operation without antiskid control action, the braking system operates in a static manner. During antiskid control braking operation, the drive of the hydraulic pump is energized while the throttling valve device remains closed until the dynamic pressure generated by the hydraulic pump has risen to the level to the static pressure then prevailing in the working compartments of the master cylinder device. Thereafter, the throttling valve device opens to relieve excess pressure. The pressurized hydraulic fluid from the auxiliary energy source is fed from the secondary side to the working side of the master piston to operate the wheel brake actuating cylinders in a dynamic manner during the antiskid control operation. An annular positioning piston is provided which becomes effective only during operation in the antiskid control mode as an abutment for the throttling valve so that the brake pedal is brought into a defined position during the antiskid control operation. A shutoff valve which is controlled in response to the movement of the positioning piston is interposed in the return conduit and prevents escape of hydraulic fluid from the master cylinder device when the hydraulic pump is out of operation.

The assembly 4 is tilted until the lower face of the bucket 2 swings out parallel to the ground, and the bucket 2 is then lowered until it rests on the ground. The assembly 4 is tilted forwardly and is reversed to withdraw the forks 32 from the pins 12.
