Title: An automatic emergency levelling device for a lift
IPC: B66B5/02
Filed: 1979-03-16
Abstract: When a power failure leaves a cable operated lift stranded between two floors an emergency leveling device is called in to play to displace the lift-car to one of the two floors. The device comprises means 7 for generating from the D.C. supplied by an accumulator battery 5, both a three phase A.C. supply for a three phase main drive motor 1 which turns the cable winch of the lift, and a single phase A.C. supply for the lift winch brake control 16. The device operates to determine which direction of rotation offers the drive motor the least resistance by automatically driving the motor first in one direction and then in the other and sensing in which direction the motor current is least. The motor is then driven in this direction to displace the lift-car to one of the two floors. <IMAGE>

Title: Method of routining parity checking circuits
IPC: H04L1/00
Filed: 1979-07-18
Abstract: The method is used where a data input/output mechanism is protected by a parity bit and is controlled by a signal whose state determines when a transfer is in progress. Data and a parity bit is presented from a controller to a parity checker P1 the output of which is a logic '1' signal if corruption has not occurred. A "Request" signal is provided via a delay line DE1 producing a positive-going clock signal for a first toggle T1 which presents a logic '0' to the clock input of a second toggle F1 providing a non-alarm signal output. If the output of the checker P1 remains in a logic '1' state when the "Request" signal goes to the logic "0" state the logic '1' is clocked into the first toggle T1 causing the output of the second toggle F1 to change state and indicate an alarm condition. A "Routine" signal is provided by the controller which is gated with the parity bit to provide a check on the output of the first and second toggles to ensure that they are not held in the logic '0' state. <IMAGE>

Title: Anisotropic membranes
IPC: B01D69/02
Filed: 1980-03-27
Abstract: Anisotropic membranes are prepared from a solution of a membrane- forming polymer in a liquid carrier. The polymer solution is provided in the form of a precursor and is then coagulated in a liquid coagulant comprising water to form the anisotropic membrane. The liquid carrier used in the methods comprises an N-acylated heterocyclic solvent which can be represented by the structure:   <IMAGE> wherein X is -CH2-, -N(R')- or -O-; R is hydrogen, methyl or ethyl; and R' is hydrogen or methyl. The methods are particularly useful for preparing anisotropic hollow fiber membranes. In forming anisotropic hollow fiber membranes, the solution of hollow fiber- forming polymer in the liquid carrier is extruded through an annular spinnerette to form a hollow fiber precursor, and the hollow fiber precursor is coagulated in a liquid coagulant comprising water to form the hollow fiber membrane. The methods are attractive for producing polysulfone hollow fiber membranes which have a homogeneously-formed, thin selective skin on an open cellular support and which exhibit high resistance to collapse. The membranes are especially useful for the separation of gases.

Title: Arc extinction in switches
IPC: H01H33/18
Filed: 1982-01-26
Abstract: A first contact 10 has an end portion 16 which engages a second contact 17, 19 in a contacts closed position and which moves transversely across a pole face of a field coil 23 and inwardly of an axis 24 of the latter during contact opening movement. The coil 23 is electrically connected in series with an arcing electrode 22, and to the second contact 17, 18. Upon contact separation, an arc is drawn between the end portion 16 of the first contact and a portion 18 of the second contact. Further opening movement of the contacts causes the arc to transfer its root from the contact portion 18 to the electrode 22 so that the arcing current then flows through the coil 23 to generate a magnetic field which causes the arc to rotate and become extinguished. Arc extinction is assisted by an electrically insulating fluid surrounding the contacts. The transfer of the arc root occurs in the arc rotation zone producing immediate rotation thereof by the magnetic field. <IMAGE>

Title: Flow meter measurement techniques
Inventor: HAMPSHIRE MICHAEL JOHN
IPC: G01F15/06
Filed: 1982-07-06
Abstract: A flow meter includes an electrical switching arrangement (3, 4) capable of attaining different electrical states in response to motion of a flow driven element (1). By counting the occurence of these states the rotation rate of the element (1) is counted and the flow rate determined. A sampling controller (5) tests periodically for a test time d and with a period T, for an attained state in the switching arrangment. When the test for the attained state is successful in times within a period of P min, defined by the minimum period of the attained state when in use, the controller confirms the attained state. By monitoring the sequence of confirmed states which appear at the output (C) of the controller (5) the flow consumption can be monitored and both power consumption and susceptibility to noise interference can be reduced. <IMAGE>
