Abstract: PCT No. PCT/FI95/00548 Sec. 371 Date Jun. 4, 1996 Sec. 102(e) Date Jun. 4, 1996 PCT Filed Oct. 4, 1995 PCT Pub. No. WO96/11512 PCT Pub. Date Apr. 18, 1996A dielectric resonator including a cylindrical dielectric resonator body having a concentric cylindrical recess. A resonance frequency controller includes an adjustment mechanism and a cylindrical dielectric adjustment body which is movable by means of the adjustment mechanism in the axial direction inside the recess of the resonator body for adjusting the resonance frequency. The frequency controller further includes a dielectric fine adjustment body attached to the adjustment mechanism and arranged inside the adjustment body so that the projection of the fine adjustment body at the end of the adjustment body within the recess in the resonator body can be adjusted by a movement of the adjustment mechanism. Thus, the frequency controller has two slopes of adjustment, whereby the adjustment is fast owing to the movement of both adjustment bodies and also extremely accurate owing to the fine adjustment function, which is achieved when the smaller adjustment body is moved alone.

Abstract: Storage vessels are fitted with weighing devices. The mixture is made up by discharging the storage vessels under the control of the weighing devices into a mixer feed channel. - The mixture is homogenised by mixing for 1-5 seconds. Before starting the mixer, the mixer feed channel is filled with components in the desired ratio, the total not exceeding four times the useful volume of the mixer. After the mixer is started, component feed is continued, the weight decrease of the storage vessels being checked every 2-20, but preferably every 4-10 seconds. If the weight decrease of any vessel is below a specified threshold, the process is stopped. - Otherwise the mass flow of feed components is checked and modified every 20-60 seconds.

Abstract: The method involves first transmitting a burst of speech data at a particular power level on one time slot of several time slots of a TDMA frame on a particular frequency channel, the traffic channel. A radio carrier is transmitted at the same power level as the speech data during a gap in the time slots on the traffic channel at a different frequency level to that of the traffic channel. This fills in the gaps in the traffic channel such that a continuous signal is transmitted.

Title: Technological method for production of prefabricated and cast-in-place fibro-concrete building constructions
Inventor: LAPSA VIDEVUDS
IPC: E04C2/16
Filed: 2000-09-20
Abstract: The object of an invention is a technological method for production of the prefabricated and cast-in-place fibro-concrete building structures. The proposed method, comprising the batching of the concrete components, addition of the fibres, casting and hardening of the structure or it's elements, is characterized in that, before the fibroconcrete mix is directed into the casting formwork, it is subjected to the one-way shearing strain in form of laminar flow until the required one-direction orientation of the fibres is achieved. After that the oriented fibroconcrete mix is carefully (accurately) filled in the formwork keeping up the obtained orientation of the fibres. According to the further aspects of an invention one way laminar shearing strain is caused under the influence of the deadweight of fibro-concrete mix overflowing the inclined flat surface or chute, or the laminar shearing flow of mix is accelerated applying an additional shearing stress to the upside surface of the mix volume through a corrugated or flat slab pressed to it, or one way laminar shearing strain is caused under influence of external pressure in a channel provided with closed section, or during the laminar flow mix is subjected to the influence of vibration.

Filed: 1987-12-18
Abstract: Packet switching network with first (DN) and second (RN) cascaded parts including first and second switching modules respectively. In the second switching modules the path selection is controlled by routing information contained in the packets. In the first switching modules this selection is performed without using routing information only for a path set up packet, whilst for the following packets use is made of routing information on the route followed by the path set up packet. Each module decides to multiplex an input stream on an output only when a calculated traffic load is smaller than a limit value. This load is calculated from traffic load parameters contained in the path set up packet.
