Title: Method of making photographic elements
IPC: G03C1/74
Filed: 1969-05-29
Abstract: In the manufacture of photographic elements, such as photographic film or paper, the support is coated by forming a free-falling vertical curtain of liquid photographic coating composition in such manner that the curtain is stable and has a uniform flow rate across its width and directing the support so that the free-falling curtain impinges thereon, while maintaining a controlled relation between the flow rate and the speed at which the support is moved, to form a thin layer of the coating composition on the face of the support. Apparatus which is particularly advantageous for carrying out this method includes means for advancing the support at the desired speed and a hopper for the coating composition which is provided with a downwardly inclined slide surface down which the coating composition flows by gravity, the slide surface terminating in a lip spaced vertically above the moving support from which the coating composition flows as a free-falling curtain.

Patent ES-397071-A1 (ES)
Title: Process and apparatus for continuous treatment of dusty, powdery and granular materials
IPC: F26B17/10
Filed: 1971-11-16
Abstract: A process for continuously drying dusty, powdery and granular materials by means of the sensible heat of gas serving simultaneously as the heating medium and the carrier gas for the materials to be treated. A gas stream containing the material to be treated is introduced tangentially into a circular path of motion and the stream so introduced moves a number of revolutions in this path to create a revolving ring of particles. The revolving ring of particles if formed while the gas is continuously drawn off below the inlet level of the gas stream with the formation of a potential vortex sink. The untreated particles flowing in from the outside displace the already revolving particles until the revolving particles, after progressive treatment, are picked up by the suction of the exiting gas stream which carries them out of the circular path. The apparatus for carrying out this proces comprises a treating chamber in the form of a ring chamber with an inlet which opens up tangentially to an outer wall of the chamber and an outlet in the form of a container which is arranged axially and at least partially under the bottom of the ring chamber, the container having a tangential takeoff duct. The ring chamber is provided with a bottom which has a slightly rising radial slope toward the center of the ring chamber. The process and apparatus may also be used for cooling the materials and for reactions carried out by exchange between gaseous and solid-phase materials.

Title: Satellite controlled digital clock system
IPC: G04G7/02
Filed: 1976-11-17
Abstract: A method and apparatus are provided for maintaining and correcting a time reference in a satellite controlled digital clock system. A time code message including time-of-year information and satellite position information is transmitted in a data stream from a transmitter on earth to a satellite orbiting the earth to be relayed back to receivers located around the world. The data is transmitted at a precise data rate. According to the invention, a local clock oscillator is phase locked with the precise data rate, thereby providing the clock system with time-of-year information by counting the pulses produced by the local oscillator. At the same time, the digital clock system assembles the time code message from the received data stream and compares the message with the time accumulated by counting the pulses produced by the oscillator. After a predetermined number of errors are detected by such comparisons, the clock system resets itself to coincide with the received time code message. If transmission of the time code message is interrupted, the clock continues counting pulses produced by the local oscillator and thereby continues keeping time undisturbed. In a preferred embodiment, the digital clock system is implemented with a firmware programmed micro-computer and the time-of-year and satellite position information is displayed on light emitting diode digital displays.

Title: Apparatus for the production of methane containing gas by hydrogasification
IPC: C10J3/00
Filed: 1978-12-04
Abstract: An improved system for producing methane-containing product gas by the hydrogasification process. With the system, solid municipal waste is comminuted and dried following which it is introduced to the lock hopper receivers for transference to an elongate hydrogasification reactor. Synthesis gas is introduced to a lower region of the reactor and the comminuted waste, including inorganic materials, is dried and converted to methane-containing product gas and char. The char is removed from the system by a variety of separation systems including cyclone separators or aspirators and the inorganic fractured waste materials pass through the reactor but are undamaged and in a sterile condition ideally suited for recovery. A gasification reactor is incorporated with the system which receives char from the process as well as oxygen to produce the synthesis gas utilized in the hydrogasification reactor. Where no inorganic materials are present, the organic materials may be introduced both to the gasification reactor to produce synthesis gas as well as to the hydrogasification reactor to produce char end product gas. The char is removed from the product gas and returned to the synthesis gas producing gasification reactor. Drying may be carried out utilizing a fluidized sand bed drying technique.
