Title: Fluid motor drive for lifting device such as a winch with accumulated pressure starting after brake release
IPC: B66D5/26
Filed: 1973-08-13
Abstract: A fluid pressure drive system for rotating a lifting device such as a winch includes a fluid motor having a drive shaft adapted to be connected to the winch which is engaged by a brake which may be actuated to stop the shaft by biasing means such as a spring. The fluid motor is driven by a pump which has a fluid pressure discharge connected to the motor which is also connected through a line to an accumulator. During pump operation the accumulator is charged with the pump operating pressure through a one way valve so that the accumulator stores the operating pressure during the operation of the motor to move the winch. The brake is released by forcing a fluid piston against the force of its biasing means to a releasing direction under the influence of actuating pressure which is supplied from a separate actuating pressure source. The actuating pressure source is connected through a control valve to a throttle and to a fluid pressure cylinder in which the fluid pressure piston which actuates the brake is movable. When the brake is applied the control valve is set so that the cylinder is vented to the atmosphere so that the biasing means may press the piston into an operative or brake engagement position. When the pump driving the fluid motor which operates the winch is stopped the control member is actuated to provide an actuating pressure connection through the throttle and to the control cylinder but also to a release valve for the accumulator pressure which is first connected to the line connected between the pump discharge and the motor to insure that the motor is held under operating pressure. The throttle in the line between the valve control and the brake control cylinder is set to regulate the pressure to the brake control cylinder in order that the brake may be released only after the accumulator pressure is communicated to the drive motor in order to insure that the drive motor is not subjected to the immediate loading of the winch would would cause a rapid unwinding of the winch.

Title: Process and apparatus for producing modified starch products
IPC: C08B30/16
Filed: 1976-06-08
Abstract: A process and apparatus are described for producing modified starch products. In the method of the invention, a slurry of starch is continuously moved at elevated temperature and pressure through a tubular heating zone and the hot fluid mass emerging from the heating zone is forced through a flow restricting zone within which the fluid mass is highly compressed. This highly compressed fluid material emerges from the confining zone into a tubular reaction zone with a sudden release of energy in the form of a fine spray or mist. The compressive forces followed by the sudden energy release act on the starch molecules to temporarily greatly increase the reactivity of the starch within the reaction zone, whereby modified starch products are quickly formed.

Patent ES-8101345-A1 (ES)
Title: Method of frame synchronization of a digital TDM communication system and arrangement for performing the method
IPC: H04J3/06
Filed: 1980-04-24
Abstract: The invention relates to a method of frame synchronization of a digital time-division multiplex communication system and to an arrangement for performing the method. During the search for a synchronization pattern of M bits in frames, each consisting of N time slots, a shift register of NxM bits is usually used. The method according to the invention has for its object to reduce the number of bit storage capacity required. The method operates as follows. At the start of the synchronization process the first bit of the synchronization pattern is expected. If this expectation comes true, the second bit of the synchronization pattern is expected in that time slot in the immediately subsequent frame etc. If the expectation does not come true then the (partially) received pattern is no synchronization pattern and the procedure is performed again in that time slot. The method is based on the recognition that it is not necessary to store the partially received synchronization pattern in a store, but that it is sufficient to store the numerical order of the bit of the synchronization pattern expected in the time slot of the next frame. Consequently, a storage capacity of Nxentire log2 M is sufficient. The method can be performed with a microprocessor or with "wild" logic circuits.
