Abstract: A powder feed hopper (10) includes a housing (12,14) which mounts a porous plate (18) adapted to support particulate powder material and receive an upwardly directed flow of fluidizing air to form an air-entrained fluidized bed (22) in the housing above the porous plate. In order to improve fluidization, a baffle plate (74) is mounted beneath the porous plate in the path of the pressurized air discharged from one or more air nozzles (78 a-d) to create a circulating flow of air-entrained particulate powder material within the fluidized bed in which the flow moves upwardly along the wall (20) of the housing and then inwardly and down-wardly toward the center of the porous plate. Additionally, stirrer blades (64) are located immediately above the porous plate to create turbulence and reduce the formation of concentrated channels of air atop the porous plate.

Abstract: A position detector (11) detects the position of a rotor (8) of a brushless motor (6). A driving signal generator (12) generates a driving signal at a timing corresponding to the detected position. While the driving signal is received, a driving circuit (14) sequentially ON/OFF-operates switching elements (Q1 to Q6) of an inverter circuit (2). At this time, a rotational speed detector detects a rotational speed of the brushless motor (13). A rotational speed controller (15) controls the duty of ON/OFF operations of the switching elements (Q1 to Q6), performed by the driving circuit (14), through a chopper signal generator (17) in accordance with the difference between a detected rotational speed and a designated rotational speed. If the detected rotational speed does not reach the designated rotational speed even when the duty becomes a preset value or more, the rotational speed controller (15) generates a phase shift signal for advancing the phase of the driving signal from that of a driving signal in a normal operation, and supplies it to the driving signal generator (12). Upon this phase shift operation, in the brushless motor (6), a magnetic flux effectively acting from the rotor (8) to armature windings (7r, 7s, 7t) is reduced as compared with a magnetic flux in a normal operation. Thus, the rotational speed of the brushless motor (6) can be reliably set to a desired value without decreasing the operation efficiency.

Abstract: A pulse circulating circuit includes inverting circuits each for inverting an input signal and outputting an inversion of the input signal. A time of signal inversion by each of the inverting circuits varies in accordance with a power supply voltage applied thereto. One of the inverting circuits constitutes an inverting circuit for starting which is controllable in inversion operation. The pulse circulating circuit circulates a pulse signal therethrough after the inverting circuit for starting starts to operate. An input terminal subjected to an analog voltage signal is connected to power supply lines of the respective inverting circuits for applying the analog voltage signal to the inverting circuits as a power supply voltage fed thereto. A counter serves to count a number of times of complete circulation of the pulse signal through the pulse circulating circuit. A circulation position detecting device serves to detect a circulation position of the pulse signal in the pulse circulating circuit on the basis of output signals of the respective inverting circuits. A control device is operative for activating the inverting circuit for starting and thereby starting pulse circulating operation of the pulse circulating circuit, and for activating the circulation position detecting means at a moment which follows a moment of starting pulse circulating operation by a given time. An output device is operative for outputting digital data as an A/D conversion result. The A/D conversion result data has lower bits composed of output digital data of the circulation position detecting device, and higher bits composed of output digital data of the counter.

Abstract: In a novel continuous gas-phase fluidised-bed process for the preparation of ethylene homopolymers and copolymers having a density d of from 0.87 to 0.97 g/cm<3>, ethylene or mixtures of ethylene and C3- to C8- alpha -monoolefins are (co)polymerised in the polymerisation zone of a gas-phase fluidised-bed reactor at pressures of from 1 to 100 bar and temperatures TR of from 30 to 125 DEG C in the gas phase in a mixed bed of finely divided polymer in the presence of a titanium- and magnesium-containing Ziegler catalyst. The heat of polymerisation produced in this reaction is dissipated by cooling the circulated reactor gas. The resultant (co)polymer is discharged from the gas-phase fluidised-bed reactor. In order to prepare a (co)polymer having a predefined density d, the (co)polymerisation in the novel process is carried out at a temperature TR which is in a range limited by an upper envelope of equation I TRH = 170 + 6d' DIVIDED 0.84 - d' (I> and by a lower envelope of equation II  TRN = 173 + 7.3d' DIVIDED 0.837 - d' (II). In equations I and II, the variable TRH represents the maximum reaction temperature in  DEG C, and the variable TRN represents the minimum reaction temperature in  DEG C, and d' denotes the numerical value of the density d of the (co)polymer to be prepared. The novel, continuous gas-phase fluidised-bed process gives, in high productivity, (co)polymers of ethylene having a particularly high bulk density and an advantageously low fines content without extremely fine material.

Abstract: In a computer network, each pair of host computers that need to exchange data packets establish a single host-to-host encryption/decryption key. Then, whenever one host computer sends a data packet to the other host computer, it first forms a predefined logical combination of the established host-to-host key and the destination buffer index to which the data packet is being sent, and then uses the resulting value to encrypt the secure portions of the data packet. The destination buffer index is included in the data packet's header, which is not encrypted. When the receiving host computer receives the encrypted data packet, it reads the destination buffer index from the packet header, forms the same predefined logical combination of the established host-to-host key and the destination buffer index to generate a decryption key, and uses the computed decryption key to decrypt the secure portions of the received data packet. If the destination buffer index in the received data packet has been modified either by noise or by an interloper, the decryption key computed by the receiving host computer will be different from the encryption key used by the sending host computer, and therefore the portions of the received data packet decrypted using the computed decryption key will be unintelligible. Thus, interlopers are prevented from breaching the confidentiality of encrypted data.
