Title: A continuous wood shearing and drying process and equipment to carry out such process
IPC: B27L5/00
Filed: 1968-06-22
Abstract: A continuous wood shearing and drying process comprises shearing wood stock into sheets by a wood-shearing machine A, passing the sheets by conveyers B, C to a drying machine D where the sheets reach a desired moisture content and, when cooled, are directed by another conveyer E to a rotating perforated drum E 1 from which the sheets are easily detached for stacking. The shearing machine A reduces wood stock into sheets and has an extractor e for passing the sheets to the conveyer B upon which the sheets are held by suction applied to a casing B 1 below perforated belts t. From the conveyer B, the sheets pass between upper and lower belts C to the drying apparatus where they follow a zig-zag path and are then passed between upper and lower belts of a conveyer E to the perforated drum E 1 . The drum is divided by a partition e 1 into upper and lower parts, the upper part being subjected by a fan to suction to hold the sheets thereon and the lower part subjected to pressure so that the sheets are easily detached for stacking.

Title: Process and installation for producing metal tubes without welding
IPC: B21B17/04
Filed: 1973-09-28
Abstract: Metal tubes are produced in the absence of welding, by boring out a solid bar on a mandrel. This mandrel and the hollow blank left after boring is introduced into a continuous rolling mill. The mandrel is retained during the rolling operation by imposing on it a speed calculated in such a way that its available length is at least equal to that which is strictly necessary for the particular rolling operation. After the blank has been rolled, the mandrel is released in such a way that the mandrel, engaged partly in the rolled blank, stops its travel through the mill. The mandrel is removed from the rolled blank which is subjected to the further-processing stages whilst the mandrel is cooled and is then inspected, lubricated and made ready for boring another solid bar.

Title: Digital phase-locked loop for speed measurement, in particular for use in antiskid control systems
IPC: G01P15/16
Filed: 1976-04-30
Abstract: A digital phase-locked loop for speed measurement, in particular for use in antiskid control systems, for the conversion of the frequency of an input pulse sequence, proportional to a speed, into a digital numerical value to be used in the digital arithmetic unit for an antiskid control system is provided wherein there is a certain numerical value which will always be the same which is allocated to any input pulse sequence and which can be applied to a first storage register and added to the contents therein. At regular intervals, determined by a clock generator, a positive digital output numerical value is generated by a detector if the content of the first storage register is above a predetermined upper limit and a negative digital output numerical value will be generated if the contents of the first storage register are below a predetermined lower limit. Furthermore, the respective digital output numerical value of the detector can be added to the content of a second storage register, observing a correct sign. The contents of the second storage register are at digital numerical value corresponding to the frequency of the input pulse sequence, with that digital numerical value always being subtracted from the content of the first storage register upon each clock pulse generated by the clock generator.

Abstract: A single point fuel injection system for an internal combustion engine including a throttle body having first and second air intake throats corresponding to first and second intake manifold planes of the engine, the air flow through each throat being controlled by throttle plates positioned within each throat. The throttle body further includes a fuel accumulating bowl which is integrally formed with the throttle body, the bowl being enclosed by a diaphragm and cover member. Within the enclosure of the fuel bowl are positioned a pair of injectors which are adapted to inject pulsed portions of fuel through a sonic nozzle and into the air intake throat of the throttle body. The injection of pulses of fuel into the throat is timed in accordance with the sensing of the crankshaft reaching a position of 15 DEG before top dead center to enhance the distribution of fuel charge from cylinder to cylinder. The fuel pressure within the bowl is controlled by a pressure regulator positioned within the enclosure formed by the bowl and housing cover, the diaphragm closing the bowl also forming the diaphragm for the regulator. The pulses to the injectors are controlled by an electronic control unit in response to sensed engine conditions.
