Patent MX-9706624-A (MX)
Title: A gas valve and a method for delivering a gas pulse.
Inventor: ZEE JAN VAN DER
IPC: F16K27/00
Filed: 1996-03-04
Abstract: A gas valve comprising a valve body which is capable of butting against a valve seat so as to close the gas valve. The valve body comprises a membrane which is fixed in the valve housing at its outside edge, in such a manner that a control chamber is formed at the side remote from the valve seat, which control chamber is connected to the gas inlet via a throttle channel. At least part of the other side of the membrane is in communication with the gas inlet, and means are provided for allowing gas to escape from the control chamber so as to open the gas valve, in that the gas pressure from the gas inlet on said other side causes the valve body to move away from the valve seat. The valve body comprises a valve member which is centrally attached to the membrane and which is substantially positioned on said other side of the membrane, which valve member sealingly mates with the valve seat.

Title: Position determining system.
Inventor: DUFFETT-SMITH PETER JAMES
IPC: H04W64/00
Filed: 1998-03-18
Abstract: The invention relates to a position determining system, for receiving digital telephone signals transmitted by a number of transmission sources (BTS). The system has a pair of receiving stations (CBU and CRU), one at a known position (O) and another on a roving object (R); a position determining processor (CPP); and means for passing a link signal (L1 and L2), from each of the receiving stations to the position determining processor, the link signal containing information about the signals received at the receiving station from the transmission sources. Each of the receiving stations is arranged to receive the signals from the respective transmission sources substantially simultaneously. The position determining processor is arranged to compare the information received from the one receiving station with the information received at the other receiving station, and to determine the time delay between the respective signals received at both receiving stations in order to determine the position of the roving object.
Patent MX-9803530-A (MX)
Title: Method of contact printing on metal alloy-coated polymer films.
Inventor: EVERHART DENNIS STEIN
IPC: G03F7/00
Filed: 1998-05-04
Abstract: The present invention comprises methods of contact printing of patterned, self-assembling monolayers of alkanethiolates, carboxylic acids, hydroxamic acids, and phosphonic acids on thermoplastic films metallized with an alloy such as nickel/gold, the compositions produced thereby, and the use of these compositions. Patterned self-assembling monolayers allow for the controlled placement of fluids thereon which contain a chemically reactive, indicator functionality. The optical sensing devices produced thereby when the film is exposed to an analyte and light, can produce optical diffraction patterns which differ depending on the reaction of the self-assembling monolayer with the analyte of interest. The light can be in the visible spectrum, and be either reflected from the film, or transmitted through it, and the analyte can be any compound reacting with the fluid on the self-assembling monolayer. The present invention also provides a flexible support for a self-assembling monolayer on a metal alloy.
Patent MX-PA99008319-A (MX)
Title: Cap assembly.
Inventor: DOUGLAS MARRIOTT
IPC: A61M5/00
Filed: 1997-05-19
Abstract: The present invention relates to an inventive non-elastomeric thermoplastic cap assembly that may be secured on an end of a generally cylindrical body at room temperatures. The cap is a deformable tubular sheath (80) having an interior surface (74), an exterior surface (76), a first open end (64) for receiving the end of the cylindrical body, and a second end (66) which is at least partially closed to inhibit passage of the cylindrical body through the second end. The sheath has a gripping region (68) adjacent the first open end to engage the exterior surface of the cylindrical body. The gripping region may include at least one ridge on the interior surface of the tubular sheath. The sheath also has a transition region (70) adjacent the second end of the sheath, which helps the sheath provide a controlled and predictable amount of retention force over a wide range of component tolerances.

Title: Lightning-conductor device
Inventor: INVERNIZZI CESARE GIULIO
IPC: H02G13/00
Filed: 1987-12-30
Abstract: An electrically conductive device (6) is positioned in the vicinity of a lightning rod point (1, 2), where it is electrically isolated from the lightning rod (1) and the ground conductor (3). This device (6) comprises a first component (7) extending radially from the lightning rod (1) and having terminal spikes (8, 9, 10) for facilitating the adjustment of said component to the potential of the surrounding atmosphere. The device (6) also comprises a second component (11) terminated by an electrode (12), which is positioned at a sufficiently short distance from the lightning rod (1) and in such a manner that a discharge takes place between the electrode (12) and the lightning rod (1) as a result of the voltage developing across the gap between said conductive device (6) and the lightning rod (1). The advantage of the system is that the efficiency of the lightning protector is greatly improved by comparison with lightning protectors provided with a radio-active source, while operating without such a source.

Patent NL-6504102-A (NL)
IPC: G10L19/00
Filed: 1965-04-01
Abstract: 1,078,829. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13170/65. Heading H4R. In a vocoder system each spectrum channel is sampled once per cycle of the fundamental frequency of the speech signal and the resulting signals transmitted in digital form. Fig. 1 shows a preferred embodiment in which speech from a microphone M is divided into a number of frequency bands by band-pass filters BP the signals from which are rectified by rectifiers G and passed through low-pass filters TP 1  to form analogue signals corresponding to the variations in energy of the individual frequency bands of the original speech. The speech is also fed through a low-pass filter TP 2  to a zero crossing detector ND to develop a pulse at the fundamental frequency of the speech. The fundamental frequency pulse is fed through a delay unit VZ, comprising e.g. cascaded monostable switching circuits, to synchronize the signal with the spectrum signals, before the signal is applied to a data processing unit EDV. The data processing unit controls the sampling switch S so that each spectrum channel is sampled one per pitch pulse. The resulting samples are fed via an analogue digital converter to the data processing system EDV for storage and subsequent transmission. The fundamental frequency signal is also digitized in the data processing unit by a counter.

Title: Analogue frequency divider with sample and hold circuit - uses frequency divisions suitable for sampling oscilloscopes, synthesisers and electronic musical instruments
IPC: H03K25/00
Filed: 1979-10-10
Abstract: The analogue frequency divider retains the modulation of an input signal, while changing the carrier frequency. It consists of two numerical dividing circuits with fixed dividing factors, a mixing circuit and a sample and hold circuit. The input signal is divided by a factor (N1) in the first divider circuit (1), and then divided by a factor (N2) in the second divider (2). The outputs of the two dividers are fed to a mixer circuit (3), the output F(S) of which is the sum or difference of the two divider outputs. The ratio F(S)/F(in) is N1 (1+-1/N2). F(S) controls a sample and hold circuit (4) which is also fed by the input signal F(in). The output frequency F(out) is related to the input frequency by the ratio F(in)/F(out) =N1 times N2.

Title: Current contact wear detector for trolley bus - provides bronze holder for carbon block with shoulders lifting hinged metal arm against spring
IPC: B60M1/02
Filed: 1982-06-09
Abstract: The carbon brushes used to make contact between overhead supply cables and the spring-loaded pick-up arms of a trolley bus are usually replaced at fixed intervals, before they are completely worn out. This wasteful procedure is obviated by the use of the present contact wear signalling system. The carbon block (38) is partially enclosed by a bronze holder (5) having shoulders on either side of the current supply wire. As the block wears down, the shoulders start to lift a hinged metal arm (21), against a spring. When the carbon block is nearly worn out, the shoulders will have lifted the arm into a horizontal position, where it will short together two probe electrodes (26,27) mounted in the upper bar of the pick-up assembly. The shorted probes cause a warning lamp to light in the driver's cab.
