Title: Semiconductor capacitor circuit
Inventor: AUSTIN KENNETH
IPC: H01L21/82
Filed: 1991-03-27
Granted: 1994-05-04
Abstract: This invention relates to semiconductor integrated circuits concerned with the realisation of different value capacitive components of a semiconductor chip by means of programming control arrangements. Programmable (IC) capacitors are implemented using a capacitive multiplier technique. Programmable capacitors comprise essentially three elements, a capacitor (C1) and one or two capacitor multipliers (M1 and M2). Capacitor (C1) is connected to the output of a first buffer circuit (B1) while programmable resistors (RP1 and RP2) are connected in series between the input and output of the buffer (B1), an output being taken from the junction between the first and second programmable resistors. By this arrangement of components, the ratio of the set values of the two programmable resistors (RP2 and RP1) determines the amount by which the capacitor (C1) value is multiplied. An overall effective capacitance value equal to (RP2/RP1) x C1 may be achieved. The final effective capacitance with two multipliers (M1, M2) approximates to (RP2/RP1) x (RP4/RP3) x C1. The value of programmable resistor RP1 is adjusted in accordance with an analogue reference signal (CCV) produced by a compensating circuit (Fig 2) to compensate for the manufacturing/processing variations of capacitor C1. <IMAGE>

Title: Improved filtering screen and support frame therefor
Inventor: HARTNUP GEORGE C
IPC: B29C70/68
Filed: 1998-02-25
Granted: 2001-06-13
Abstract: A method of constructing a polymer support frame (10) over which woven wire cloth (158,159) is to be stretched and secured to form a sifting screen is described. The method comprises the steps of locating a reinforcing wire frame assembly in a mould tool. The wire frame comprises two parallel spaced apart arrays of reinforcing wires (48,50,54,56,60,62,64). After closing the mould, liquid polymer is injected into the mould tool so as to wholly encapsulate the wire frame and to form an article having an open central region criss-crossed by intersecting orthogonal ribs (14,16) bounded on all sides by a rigid flange. Each of the ribs (14,16) contains two of the parallel spaced apart wires of the frame assembly. After permitting the polymer to cure, the tool is opened and the article is removed. The wire frame assembly is located and held in shape and position by applying an inward force on opposite faces of the wire frame assembly within the mould tool, by fingers protruding inwardly from inside faces of the tool. The fingers engage the wire matrices when the tool closes. The polymer is typically a glass-reinforced plastics material, and in order to assist in bonding the wire cloth to the support frame (10) the faces of peripheral edge regions of the support frame (10) over which woven cloth (158,159) is laid and to which the cloth (158,159) is to be bonded by heating, are formed during moulding with a plurality of substantially parallel ridges (30,32).

Title: Duplex amplifier for intercom
Inventor: JORGEN BROSOW
IPC: H04L/
Filed: 1981-01-23
Granted: 1990-12-20
Abstract: The output (R,F) of the telephone line (KL,a,b) is connected to a point (P,G) at the input of the receive channel. This is accomplished via a resistance network (R15-R21) with whose help the amplitude of the signal coming from the transmit channel can be made equal to the amplitude of the signal entering the receive channel. Coincident signals cancel whilst noncoincident wanted signals can be processed. The receive and transmit channels are open in the quiescent state and attenuated in the low frequency band of the transmission waveband. This attenuation is eliminated when the channel concerned is in operation.. The amplifier is open in both transmission directions for most of the time and the duplex mode only interrupted briefly in especially adverse conditions.

IPC: H04M/
Filed: 1980-02-22
Granted: 1990-11-22
Abstract: The signal generator provides the ringing signals for several subscriber telephones each of which has a different frequency. These frequencies are generated by a sweep oscillator circuit followed by a programmable filter. A clock circuit is connected to a five bit binary counter (20) and to a timer circuit (30). The timer comprises a divide-by-ten counter (32) followed by a four bit counter (32). A four bit decoder (33) initiates the fove bit counter whose outputs are connected to different resistors (41-a-e) in an oscillator (41). The oscillator frequencies are amplified (50) and applied to a programmable filter (60) which is also connected to the five bit counter. The filter filters the triangular shaped oscillator sweep frequency to form a single sinusoidal frequency which is raised to the line ringing voltage by amplification.

Granted: 1977-03-10
Abstract: Disclosed is an improved composition and process for the heavy metal displacement plating of a zinc surface. The improved process provides for contacting the zinc surface with a solution containing at least one soluble stabilizing compound containing antimony, tin, copper, lead, germanium, vanadium, arsenic or tungsten. This contact may be effected either by pretreating the metal surface prior to displacement plating or by including the stabilizing compound in the displacement solution itself. The composition is an aqueous one containing both a heavy metal ion and the stabilizing compound. The disclosed process improves the displacement plating composition's resistance to degradation and consequent loss of efficiency.
