Patent EP-0155740-A3 (EP)
IPC: H04M1/60
Filed: 1985-03-18
Abstract: A loudspeaking telephone includes first and second 
comb filters (2,4) one in the receive path and the other in the 
transmit path and a control arrangement (11) which controls 
the pass and stop bands of the comb filters (2,4). The comb 
filters (2,4) have interlaced characteristics, i.e. the stopbands 
of one lie in the passbands of the other and vice versa. Thus 
signals passing through the comb filter (2) will be rejected by 
the comb filter (4) thus preventing their being emitted by the 
loudspeaker (3) and being coupled back to the microphone 
(1).  
     The pass and stop bands of the comb filters (2,4) are 
interchangeable in dependence on whether the loudspeak­
ing telephone instrument is being used by the called or 
calling party. The control arrangement (11) detects which 
party is using the instrument and either interchanges the 
positions of the comb filters (2,4) by means of switches 
(Figure 1) or modifies the characteristics of the individual 
comb filters (2,4) by switching their internal circuitry (Figure 
2).

Patent EP-0270727-A3 (EP)
IPC: F16K27/02
Filed: 1987-02-13
Abstract: This invention is intended to solve such problem that a 
valve casing for use in a butterfly valve formed by press 
working is advantageous in the aspects of productivity, 
thickness and weight, but has a serious disadvantage of 
breakage or deformation lowering in sealing performance 
due to getting out or ageing of the seal ring when the 
valve is mounted on pipe line and clamped from both sides. 
From this point of view, a valve casing according to this 
invention is formed into a double structure composed of an 
inner shell and an outer shell, the inner shell comprising 
a cylindrical part defining a bore and seal ring receiving 
portions formed on both ends with their diameters enlarged 
larger than the cylindrical part, substantially forming a 
S-shape in section the outer shell defining a space by 
surrounding a whole outer periphery of the inner shell, 
and the inner shell and the outer shell being superposed 
each other at both end of the valve casing.

Title: Improvements relating to thermal control units
IPC: H01H37/00
Filed: 1987-07-28
Abstract: An element protector control for protecting the electrically powered heating element of a kettle against overheating has primary and secondary (or back-up) modes of operation. The primary protection mode utilizes a dished, snap-acting bimetal (22) which is oriented so that the side of the bimetal which is convex when the blade is cold faces the heating element head (24), and the bimetal is held in close thermal contact with a rear surface of the element head. The bimetal determines the condition of a pair of switching contacts (32, 33) provided in the control. The bimetal is mounted in a carrier (21) which is spring biassed towards the element head and, for providing the secondary protection mode, the carrier is formed of a thermoplastics material so that in the event of failure of the primary protection in an overtemperature situation so that the element temperature continues to rise, the carrier will collapse towards the element head, and the collapse of the carrier is arranged to disconnect the control from its power supply terminals.

Title: Method for determining the control voltage of a voltage-controlled oscillator in a phase-locked loop
IPC: H03L7/18
Filed: 1988-11-24
Abstract: A phase-locked loop is formed by a series circuit of a counter, a register, an arithmetic unit, a low-pass filter, a PI-filter, and a voltage-controlled oscillator. The digital, internal clock signals generated by the oscillator are counted in a counter and are transferred into the register and stored as a current counter reading at points in time determined by time interval clock signals. For example, the time interval clock signals are acquired from reference clock signals by means of a divider and exhibit a lower frequency than the internal clock signals. A drive signal in digital form is determined in the arithmetic unit on the basis of the current counter reading, on the counter reading of the preceding evaluation interval, and on a rated value. This drive signal proceeds via a digital low-pass filter, PI-filter, and D/A converter to the control input of the oscillator, and controls the latter such that the internal clock signals coincide in phase with the reference clock signals.

The polymer is cut into lenses, and the lenses are treated with acetyl chloride or another suitable chemical so that their surfaces become hydrophilic. The result is oxygen-permeable, hydrophilic, daily and extended-wear, hard contact lenses.

Support plates (24) on the cross-transfer assembly are moved apart to release the convector panel (4) which drops onto the prime panel (2) at the contacting station. Gripping means (26,28) hold the two panels as they advance in unison to an attachment station, and a clamping finger holds the convector panel in the correct position on the prime panel while two pairs (34) of spot-welding guns spot-weld the forward edge of the panels. The gripping means then releases the welded panels and returns to its initial position to receive the forward edge of the next prime panel.

Title: Device for generating a reference pattern with a continuous probability density function derived from feature code occurrence probability distribution
IPC: G10L15/06
Filed: 1989-02-08
Abstract: In a system for recognizing a time sequence of feature vectors of a speech signal representative of an unknown utterance as one of a plurality of reference patterns, a generator (11) for generating the reference patterns has a converter (15) for converting a plurality of time sequences of feature vectors of an input pattern of a speech signal with variances to a plurality of time sequences of feature codes with reference to code vectors (14) which are previously prepared by the known clustering. A first pattern former (16) generates a state transition probability distribution and an occurrence probability distribution of feature codes for each state in a state transition network. A function generator (17) calculates parameters of continuous Gaussian density function from the code vectors and the occurrence probability distribution to produce the continuous Gaussian density function approximating the occurrence probability distribution. A second pattern former (18) produces a reference pattern defined by the state transition probability distribution and the continuous Gaussian density function. For a plurality of different training words, a plurality of reference patterns are generated and are memorized in the reference pattern generator.
