Patent EP-0211279-A2 (EP)
Inventor: SALZMAN RONALD N
IPC: B01F7/00
Filed: 1986-07-14
Abstract: Apparatus for mixing liquid and liquid suspension mediums in vessels with a mixing impeller shaft system of a composite of fibrous and plastic material of a structural configuration to enable the use of such material in commercial and industrial applications where the reaction loads of the medium on the system militate against the use of composite fibrous and plastic material. The system utilizes impellers having blades which distribute the reaction load through a hub on a mounting area of a shaft with keys and keyways in a manner to avoid stress risers unamicable to the composite material and which can cause failure thereof. Separate keys and keyways are provided to oppose the thrust due to the reaction loads and to oppose the torque due to such loads. Plural thrust keyways may be used to enable the impeller to be located at different positions on the shaft and at selected heights above the floor of the mixing vessel. Proplets on the tips of the blades extend entirely in the direction of the low pressure surface of the blades to control the flow field in the vessel and provide a more axial velocity profile of the inlet flow to the impeller which is nearly axial and substantially reduces the strength of the tip vortices.

Abstract: An audio/video system comprises a plurality of units of different types and a plurality of units of like types; for instance a plurality of amplifiers, video recorders, monitors, etc. Each unit includes a remote control (RC) receiver. Receivers of like type units and/or RC receivers of different type units are connected in cascade in order to control all units using only one single remote control (RC) transmitter. This transmitter transmits control packets having a packet header, a characteristic code, and a control command. The characteristic code includes a unit type code defining the type of unit to be controlled and a unit number code defining the specific unit of that type within the string of cascaded like units. The control packet dribbles down the string of cascaded RC receivers until it has reached the unit having that particular unit number.

Abstract: A nonlinear control system adapted to drive and control the speed, stroke, phase and center position of a reciprocating linear motor by means of phase locked loop techniques and the electromechanical filtering properties of linear motors. The control system comprises a tri-state switching amplifier in conjunction with 3 distinct feedback control loops to accurately determine the amplitude, center position and phase of the motor. The first feedback control loop includes a low pass averaging circuit and compares the motor position with a reference signal to achieve the desired motor position. The second feedback control loop includes a peak detector and determines the stroke of the reciprocating motor. The third feedback control loop operates as a phase locked loop to control the phase of the motor. The control system provides high efficiency, high reliability and low cost.

Abstract: Method and apparatus are disclosed for accurately determining position from GPS satellites (12,13,14) and received on a ship (10) using the following observable signals: C/A code group delay observable τ; 308 f o  implicit carrier phase observable ϕ; L1 band implicit f o  carrier residual phase observable ψ L1; and L2 band implicit f o  carrier residual phase observable ψ L 2 . A precise measurement of the group-phase delay range to each satellite is made based upon the L1 center frequency carrier phase. A correction for ionospheric effects is determined by simultaneous observation of the group delays of the wide bandwidth P code modulations in both the L1 and L2 bands. These group delays are determined by measuring the phases of carrier waves implicit in the spread-spectrum signals received in both bands. These carriers are reconstructed from both the L and L2 band signals from each satellite without using knowledge of the P code. The unknown biases in the L1 center frequency carrier phase range measurements are determined from simultaneous, pseudorange measurements, with time averaging. The instantaneous position of the ship (10) may then be determined from the ranges so determined, with both the bias and the ionospheric effects having been eliminated.

Abstract: A magnetic field sensor coil wherein the coil is formed into a shape comprising two generally C-shaped limbs (2, 3) one within the other, one of these limbs being covered by a magnetic screening material (4). In operation an e.m.f. is induced in each turn of the unscreened part of the coil (3) whilst no e.m.f. is induced in the screened part (4) and so the total e.m.f. induced is approximately equal to the e.m.f. that would be induced in a simple concentrically wound coil of the same number of turns and of the same dimensions as the unscreened portion of the coil. The coil according to the invention is especially suitable for use with a system for monitoring an electric motor where the coil may be placed adjacent the motor end plate concentrically around the motor shaft without having to uncouple the motor from its load.
