Title: Linearization of amplitude response and phase correction for amplifier
Inventor: ISOTA YOJI
IPC: H03F3/189
Filed: 1990-12-24
Abstract: A high frequency amplifier circuit comprises an amplitude characteristic correction circuit and a phase characteristic correction circuit for compensating the non-linearity of the input-output characteristics of the amplifier. The amplitude characteristic correction circuit varies the drain voltage or the collector voltage of the amplifier in accordance with the envelope level of an input signal in such a manner that the relationship between the amplitude of the output of the amplifier and the amplitude of the input signal has linearity. On the other hand, the phase characteristic correction circuit provides a quantity of phase shift to the input signal in accordance with the envelope level of the input signal, and the phase-shifted input signal is applied to the amplifier in such a manner that the phase of the output of the amplifier and that of the input signal coincide with each other. <IMAGE>

Title: Fabry-perot optical filters
Inventor: ROBERTSON ALEXANDER JOHN
IPC: G02B6/34
Filed: 1991-04-12
Abstract: Simple polarisation independent wavelength tuning components (filters) employ a filter element, such as a Fabry-Perot etalon element, which is such that light input thereto undergoes two element transitions with orthogonal polarisation states before being output, in order to suppress polarisation noise. In one arrangement, two etalon filters 20, 21, are separated by a half wave plate 22 providing the necessary polarisation rotation. The two etalon filters and the half wave plate comprise a single element rotatable about the single axis. 23 and 26 are optical fibres. Alternatively, light may be passed through a single filter (etalon) (30, Fig. 10) twice using a Faraday rotator/mirror combination (33, Fig. 10). <IMAGE>

Title: Interface for a supervised multi-input audible warning system
Inventor: NICOL JOHN JAMES
IPC: G08B29/06
Filed: 1991-05-02
Abstract: An interface for a supervised multiple input, audible warning system is disclosed. The interface continuously monitors or supervises a plurality of circuits (10, 12, 14 in fig 1 not shown) between a control unit 20 and an alarm unit 16 for electrical faults. Each circuit represents a separate alarming condition. All the circuits are coupled to but normally isolated from each other and a common circuit 58 for driving a piezoelectric device. The isolation is accomplished by means of a semiconductor switch 52 normally reverse biased. The semiconductor switch 52 prevents the supervising current of one circuit from driving the piezo by isolating all possible flow paths to all circuits without current flow in the alarming direction. Upon sensing an alarming condition, the direction of the current in the alarming circuit reverses resulting in forward biasing the semiconductor switch 52. The current in the alarming circuit, no longer isolated from the common circuit 58, actuates the common circuitry necessary for generating the audible warning. The interface circuits may be connected to an addressable micro controller (64 in fig 5 not shown) for selecting a multitude of sounds. <IMAGE>

Title: Balanced field direct current motor
Inventor: WHYLE WILLIAM
IPC: H02K23/08
Filed: 1991-07-18
Abstract: A direct current electric motor primarily designed to drive electric vehicles. Torque is developed by repulsion and attraction see Figs 2a, c from all motor cars during part of the commutated cycle, sets of winding being shorted, Fig 2b, at alignment. The magnetic field of both stator and armature pole faces at 2c are balanced to reduce magnetic drag. This is achieved through all values of current by having a windings ratio of 1:2 respectively. The commutator brushes may be mounted in an advance and return mechanism. The short length allows greater numbers of conductor turns for relatively low resistance, increasing amp-turns potential, giving greater economy of power and permits a modular arrangement. <IMAGE>

Abstract: A frame for assembly with a pallet base 1 Fig 1 to form a container consists of two identical frame parts 2, 3. Each frame part has a hook shaped tongue 6 on a hinged wall 9Z and a pocket 7 in a hinged wall 9a. For assembly of the frame the tongue 6 on one frame part is inserted into the pocket 7 of the other frame part with a pivotal motion so that a retaining part 6a of the tongue engages behind a retaining surface in the pocket to restrain the two frame parts from being separated. Each frame part carries a pivotted latch member 17 Fig 5 and a lug 16. Upon assembly of the frame the lug 16 is captured by pivotal movement of the latch member 17 to retain together the frame parts 2, 3 and prevent those parts from being pivotted in a sense to unhook the tongues from the pockets in which they are respectively received. Secondary locking means may be provided by which the latch member 17 can be retained in engagement with the lug 16. The latch member 17 engages with the lug 16 in a direction perpendicular to the plane of the co-operating walls 9a and 9Z and preferably the secondary locking means is actuated in a direction parallel to the plane of the walls 9a and 9Z. The secondary locking means may be a sliding bolt on the member 17 which engages a recess in the lug 16. <IMAGE>
