Title: Fluorine-containing bismaleamic acids and bismaleimides useful for thermosetting resins
Inventor: MARUTA MASAMICHI
IPC: C07D207/448
Filed: 1989-09-14
Abstract: Fluorine-containing bismaleimides are obtained by dehydrating and cyclizing reaction of corresponding bismaleamic acids, which may be obtained from amines and cyclic anhydrides, for example maleic anhydride. A mixture of a bismaleimide of the invention and a diamine is useful as a thermosetting resin composition. At 100-300 DEG C the resin composition undergoes addition polymerization to turn into a solid resin which are high in moisture resistance and low in dielectric constant. For use in the resin composition it is preferable that both R<1> and R<2> in the general formula of the bismaleimide are -CF3. The bismaleimides are of the formula:-… …<IMAGE>… wherein A represents a divalent organic group having an ethylenic unsaturated bond; Rf represents fluorine atom or a perfluoroalkyl group; R<1> and R<2> are the same or different and each represent hydrogen atom, methyl group, ethyl group or a halogenated methyl group; and each… …<IMAGE>… is at the m- or p-position with respect to the aromatic ether bond -O-.

Title: Knocking detection device for an automotive engine
Inventor: MATSUURA TAKASHI
IPC: F02P5/152
Filed: 1990-04-17
Abstract: A knocking detection device for an automotive engine mounted on a vehicle comprises a knock sensor (18), and a crank position sensor (11). A first calculating circuit (32) responds to the signals from the crank position sensor (11) for calculating an engine speed of the engine and a first setting circuit (33) sets a knocking detection term in one cycle of the engine corresponding to a period having the possibility of knocking. An A/D converter (3) converts analog waveforms from the knock sensor (18) into digital data every sampling period and a second calculating circuit (34) calculates a knocking level of the engine (1) based on an average value of the digital data from the conversion circuit (3) during the knocking detection term set by the first setting circuit (33). A second setting circuit (35) responsive to the engine speed generates a map (36) of discrimination levels for different speeds and a determination circuit (37) compares the knocking level output from the second calculating circuit (34) with the discrimination level set by the second setting circuit (35).   <IMAGE>

Title: Heat treatment of expansible materials to form lightweight aggregate
Inventor: KYFFIN ROBIN ANTHONY
IPC: C04B20/06
Filed: 1990-10-10
Abstract: Adhesion of particulate material (e.g. slate or clay), undergoing heat treatment in the region of its fusion temperature (e.g. 1200 - 1300 DEG C), to an underlying hearth (14) is prevented by providing a thin layer of sand over the hearth before the material is distributed thereover. The hearth (14) is preferably annular and moved successively through a sand supply zone (SZ), a pre-heating zone (PHZ), a charging zone (CZ) (where material to be treated is supplied), a heat treatment zone (TZ) and a discharge zone (DZ). Discharge of the heat-expanded product is facilitated by the presence of the sand layer, and cooling at this stage is no longer necessary. Intermittent supply of sand may be adequate to replenish that removed along with the expanded product. <IMAGE>

Title: Multi-channel acoustic system
Inventor: KYOUNO NOBORU
IPC: H04R3/14
Filed: 1991-04-29
Abstract: In a digital channel divider 10, a plurality of filters are connected in parallel, which can set a desired transmission frequency response optionally for a digital input signal, so that signals outputted from each filter are outputted independently. In order to flatten the amplitude characteristic of an overall transmission frequency response of each channel and to obtain a linear phase frequency response, an inverse filter is used wherein a time series impulse response is calculated based on an inverse characteristic and this time series impulse response is made to be a filter factor, and this filter factor and the digital input signal are calculated by convolution operations. Use is in a multi-channel amplifier system or multi-way speaker system. <IMAGE>

Patent GB-2259259-A (GB)
Title: Wetting mechanism for a doll
Inventor: MONTGOMERY ROBERT BENNIE
IPC: A63H3/24
Filed: 1992-08-26
Abstract: A wetting mechanism for a doll comprises a hollow hemisphere 7 which is divided internally by a wall 22 into two chambers (20, 21). The first chamber (20) has an inlet 10 for the admission of water and the second chamber (21) has an outlet 12 for the exit of water. The wall 22 only allows water in the first chamber to pass to the second chamber after the doll has been suitably orientated. This allows the wetting of baby to be mimicked in a doll simply by tipping the doll and not having to squeeze the doll's tummy or arm. In addition to orientating the doll, water may pass from the first to the second chamber when the level of water in the first chamber is greater than the height of the wall 22 which separates the chambers. The doll may include sound producing means including terminals 32, 33 which in use are short-circuited by water passing into the second chamber, so that a crying sound is produced. Other sounds such as those appropriate to feeding, can also be produced. <IMAGE>

Patent GB-2271857-A (GB)
Title: External compensator of potential transformers
Inventor: XU QIFENG
IPC: G01R15/18
Filed: 1993-08-02
Abstract: The errors of potential transformer (PT) mainly consist of two parts: the first is the no-load error which is caused by the magnetising current in the primary impedance the second is the load error which is caused by the load current in the primary and secondary impedance. The iron core has non-linear characteristics and the magnetising impedance is a non-linear function of the primary voltage so it is necessary to compensate no-load error nonlinearly. Owing to PT running in a state of high peak magnetic flux density and the iron core having a non-linear magnetisation characteristics, there are an abundance of higher harmonics in the magnetising current producing large voltage drops. In order to compensate these drops, it is necessary to produce an equivalent voltage in the PT's secondary loop. It is tens or hundreds meters from PT to secondary devices, therefore the magnitude error caused by the impedance of secondary wire is very large. Based on the principle of physical similarity between a specially designed model PT and the main PT the present invention gives a measure of the magnetising current and through an amplifier A1 replaces any voltage drop this has caused. A small auxiliary CT is used to sense the load current and through another amplifier A2 replaces any voltage drop this has caused. There is no need to modify the original PT since the compensation can be made near the load. An output of module PT To is applied via an isolating transformer T1 and a phase shifter including an amplifier A1 to an adder for combination with the current transformer CT's output also supplied via a further phase shifter. The adder min s output is supplied to a compensating transformer T2. <IMAGE>
