Title: Flow measurement in rectangular ducts - uses constriction to set up pressure difference from which velocity is determined
Inventor: AKASHI KOICHIRO
IPC: G01P5/14
Filed: 1975-03-14
Abstract: A flow measuring device uses a constriction comprising two baffle plates (22) placed in a rectangular duct (21) to set up a pressure difference. From the pressure difference, measured via ports (23a, 23c) either side of the constriction, the speed of flow in the duct is determined. The constricting plates (22) are mounted directly opposite each other on inner walls of the duct (21). The plates have rectangular edges, are parallel sided, and are symmetrically mounted about the centre line of the duct. They may be mounted specifically at 90 or 180 degrees to each other or at an angle of less than 180 degrees. The dependency of pressure on velocity varies with this angle according to the Reynolds number.

Title: Rapid development of welding pressure - used on polypropylene coated containers to obtain hermetic seals between contaminated surfaces
Inventor: SELLE MANFRED
IPC: B29C65/18
Filed: 1975-05-09
Abstract: Process for welding joints between thermoplastic (polypropylene) coatings on lightweight plastic coated metal containers by pressing heated surfaces together, where the mechanism for consolidating the weld interface develops the max. required welding pressure in 20 pref. 3-5% of the period required for the welding cycle. Esp. for sealing containers of >1000ml. capacity. Rapid development of the moulding pressure ensures a good weld between surfaces which are partially contaminated by material being previously put into the container, where the contamination results in nonhermetic seals if weld pressures are developed slowly. The mechanism is efficient at generating a high thrust to be sustained by the hydraulic system without requiring a high (pressure x swept volume) prod. from either of the power cylinders involved.

Title: Car light switch with safety interlock - with two separate inputs to prevent driving with only parking lights
Inventor: PESCHL JOHANN
IPC: B60R16/03
Filed: 1975-09-25
Abstract: The car lights are linked to a double pole switch supplied from two different circuits. One line links the parking lights directly to the battery. This allows the parking lights to be switched on with the ignition switched off. The second line links the driving lights, or headlamps, to the battery via the ignition switch. If the light switch is on for parking, then when the ignition is switched on and the car driven away, the headlamps are automatically operated. Also if the lights are switched on while driving in poor visibility, then it is impossible to switch on only the parking lights. The vehicle is thus always in a properly lit condition. The headlamps are automatically switched off when the ignition is switched off.

Title: Flyer braking mechanism - using a light beam with discriminating circuit to allow for fibre flocks in the operating zone
Inventor: MORI MITSUO
IPC: D01H13/16
Filed: 1976-06-09
Abstract: In a multi-unit spinning and winding machine, the drive to the flyer has to be braked in the event of a slubbing breakage in the outer winding layer on one of the spools. At lease one beam of light is transmitted from a light source to a photodetector on a path running close tothe spools and particularly along the line of the flyers. The incidence of interruption of this light beam through fibre flocks is determined for a given time period. If this interruption rate increases during the given time period, then the drive to the flyers is stopped and brought to rest. The system discriminates between ambient disturbances and a true breakage of the material, partic. in the wound zone, to give a positive braking action only when it is required.

Title: Free-running material e.g. pulverised coal charging system - with flow rate controlled gate setting and carrier gas admission
Inventor: FEDERHEN BERND ING GRAD
IPC: C21B5/00
Filed: 1977-03-31
Abstract: Free-running bulk material, e.g. pulverised coal, can be charged into a pressure vessel, e.g. a gasification reactor, by passing it through a flow rate metre. Its actual readings are compared with a desired value and the cross-section of the passage is controlled by the difference. The material flow also receives a gaseous transport medium as a function of the flow rate before it enters the admission line to the reactor. The result is a uniform charging rate of a reactor even if several admission lines are used. Any overflow or clogging of the conveying lines is eliminated.
