Title: Alarm signalling over lines - switches zener diodes to discriminate between line faults and genuine alarms and includes transistor for triggering
IPC: G08C19/30
Filed: 1971-06-19
Abstract: The remote station (M) is connected to the monitoring station (U) by a line pair (a, b). The remote station contains a resistor (R11) and a Zener diode (Z11) which is normally short circuited by the alarm switch (K11). The monitoring station contains a batter, a Zener diode (Z2) and a controller (K) which monitors the line voltage and current. The two Zener diodes each operate at half the battery voltage and are both connected in opposition to the battery. The alarm is given by opening the alarm switch (K11), whereupon the line current falls to zero. The controller responds by triggering a transistor (T) to short circuit its Zener diode (Z2), which should restore the normal line current. This distinguishes a genuine alarm from a line fault and the alarm (A) is then energised. A higher voltage Zener diode (Z12) and a different resistor (R12) can be switched (k12) for signalling over the same line pair without risk of triggering the alarm.

Patent DE-2228490-B2 (DE)
Title: Reduction of setting time of deflected vibratory structure - using deflection by external force variable in time
IPC: G01R11/10
Filed: 1972-06-12
Abstract: Apart from the external force variable in time, an elastic force and a damping proportional to speed also act on the structure. The damping proportional to speed is set accordingly at a higher degree than the aperiodic limiting case. At the start of a setting operation the structure receives an additional pulse which is proportional to the external force or the deflection caused by it. The pulse is so rated that it corresponds to the pulse taken from the structure by friction coupling during the setting operation. The method can be used to reduce the setting time of the moving coil of a moving-coil voltmeter.

Title: Hinge for a bin lid
Inventor: HANLON JOHN JOSEPH
IPC: B65D1/14
Filed: 1996-04-26
Abstract: Provided is a hinge for a bin lid, normally made from deformable plastics material by rotational or centrifugal moulding, which hinge comprises a rectilinear series of spaced apart hinge members disposed along one edge of the lid, wherein each hinge member of the series (except the two at the ends thereof) bears an open channel adapted to embrace a common hinge pin without completely surrounding it. This construction eliminates the need for detachable mould parts (e.g. metal plugs, such as brass pins) in the mould, which parts constitute an inconvenience in conventional moulding, due to their tendency to move with respect to the mould, before or during moulding. A method of centrifugally or rotationally moulding such a lid without using detachable mould parts is also provided.

IPC: H03H9/215
Filed: 1977-03-22
Abstract: A quartz crystal tuning fork vibrator comprises a monolithic quartz crystal vibrator having a tuning fork shape with a plurality of vibratable tines. A set of electrodes are adhered to opposite surfaces of the tuning fork vibrator and are arranged in such a manner that when suitable alternating voltage is applied thereto, the tines undergo flexural vibration in their fundamental or resonance mode. The electrodes on each tine surface are preferably arranged in groups of four with the center two being applied with voltage of one polarity when the outer two are applied with voltage of the other polarity thereby establishing electric fields within the tines at the outside portions thereof while no electric field is established at the center portion of the tines. All of the flexural strain is thus confined to the outside portions of the tines thereby lowering the amplitude of vibration of the tine ends to the order of 5 mu -10 mu .

Abstract: A continuous speech recognition system utilizes a format memory (14) which specifies a sequence of word sets and a plurality of words, or reference patterns, which may be included in each word set. The input pattern sequence is divided into all possible partial patterns having start points p and end points q, and each of these partial patterns is compared with all reference patterns to derive elementary similarity measures. The elementary similarity measures for each combination of a partial pattern and a permitted word in a word set under the specified format are then examined to determine the optimum input pattern segmentation points and corresponding sequence of reference patterns which will yield a maximum similarity result. The maximum similarity is represented by   <IMAGE>   where S(p(x-1), p(x),n(x)) indicates the degree of similarity between an input partial pattern having a start point p(x-1) and an n point p(x) and a reference word unit n(x) within a word set fx, and K represents the number of word sets permitted according to the specified format.

Abstract: An MOS memory has a main array of memory cells (10, 12) and a plurality of spare memory cells (22, 24). Typically, each memory cell is tested for operability by a conventional probe test. A redundancy scheme is provided for substituting spare memory cells for memory cells found to be defective. An on-chip address controller (38-50) responds to the probe test finding a defective cell by permanently storing and rendering continuously available a fully asynchronous electrical indication of the address of the defective cell. The address controller (38-50) compares its stored data with memory cell information received during normal memory operation, and generates a control signal indicative of the receipt of an address which corresponds to a defective cell. A spare cell selector (106, 108) responds to the control signal by electrically accessing a spare memory cell and by prohibiting access of the defective memory cell.

Granted: 1992-06-10
Abstract: Manufactured goods such as cast components to which molding sand is still adhering, are treated in a vibratory conveyor chute for cleaning and cooling the goods. As the goods travel down the chute they are exposed to force components extending perpendicularly and across to the travel direction along the length of the chute. These force components impose on the goods a revolving motion along a helical path. This revolving motion may be improved or intensified by directing the resulting force components (R, R') of the force causing the revolving motion to extend at a spacing from a so-called "center of gravity line" (S, S') defining or interconnecting the center of gravity points along the length of the vibratory chute system. This spacing causes a distribution of the goods (11) in the chute such that the goods (11) have a slanted surface (10) in the chute (1). Thus, the vertical acceleration values (kv) are larger at the upper return zone 26 than they are at the lower return zone 27. This type of treatment combined with the conveying movement is applicable to various kinds of goods and treatment procedures.
