Title: Apparatus for detecting subsynchronous current in power systems
IPC: H02H7/06
Filed: 1978-01-05
Abstract: Apparatus for detecting the presence of subsynchronous current components in an electrical generating or transmission system is disclosed. Input signals, representative respectively of line voltage and current, are conditioned and initially filtered to suppress high frequency noise. The input voltage signal is further limited and filtered to produce a constant amplitude, sinusoid reference. The input signals are then multiplied to yield the subsynchronous current signal components, if any, which undergo further filtration by a bandpass filter circuit. In addition, the detection apparatus is provided with circuit means for insuring protection against overvoltage and current surge conditions.

Title: Method for polypeptide production involving expression of a heterologous gene, recombinant microbial cloning vehicle containing said gene and bacterial culture transformed by said cloning vehicle.
IPC: C12N1/21
Filed: 1978-11-06
Abstract: Specific polypeptides are prepared by expression of a heterologous gene coding for them in a recombinant microbial cloning vehicle. The gene is arraged to be in reading phase with a DNA sequence coding for another polypeptide so that when the DNA is expressed a precursor protein is produced comprising both the desired polypeptide and the additional polypeptide, there being a cleavage site between them where the precursor protein may subsequently be cleaved. Plasmids or cloning vehicles containing this type of DNA sequence may be used to transform bacterial cultures in particular to enable the bacteria to produce an immunogenic substance comprising a polyeptide hapten, the DNA sequence coding for the hapten and an additional protein sufficient in size to confer immunogenicity on the product of expression and enable antibodies to be raised to it. Alternatively, the bacteria may be enabled to produce a desired polypeptide product e.g. somatostatin linked to additional protein from which the desired product may be cleaved.

Title: Method of and system for generating energy from solar and wind energy sources
IPC: F24V50/00
Filed: 1979-01-24
Abstract: Solar and wind energy sources are combined into a unitary system for generating electrical energy.

Title: Digital speed pattern generator
IPC: B66B1/16
Filed: 1979-05-04
Abstract: A digital speed pattern generator which may have acceleration, constant velocity, and deceleration phases, which is particularly advantageous for short runs in which the constant velocity phase is not reached, as well as for longer runs, such as required for high speed elevators. A first digital speed pattern signal is generated from a pulse train which has a constant average frequency related to maximum jerk. A second digital speed pattern signal is generated during the slow-down or deceleration phase from distance pulses responsive to movement of the elevator car. The first digital speed pattern signal is suitable for use as the effective speed pattern for motor control throughout the acceleration, constant velocity and deceleration phases of the speed pattern signal. The first digital speed pattern signal is slaved to follow the second digital speed pattern signal during a deceleration phase of the speed pattern, within the constraints applicable to the generation of the first digital speed pattern signal.

Title: Transistor switching means
IPC: H03K17/08
Filed: 1980-05-29
Abstract: Transistor switching means in which a principal transistor (T5) feeds into a load (Rc) when a control signal saturates a control transistor (T1), a resistance bridge (R3,R4) fed by a source (VAL) then polarizing the base of the principal transistor (T5). An auxiliary transistor (T3a) has its base coupled to the collector of the transistor (T5) by means of a diode (D2a) and one of the two polarization resistances (R10-R11). When the collector-emitter voltage of the principal transistor becomes too strong as a result of a short-circuit in the load, the auxiliary transistor (T3a) is saturated and blocks the principal transistor (T5). Application to detectors of the type having an electro-luminescent diode excited by pulses these pulses, applied to the auxiliary transistor (T3a) block it momentarily in order to ensure the re-setting of the circuit when the overload has disappeared.
