Title: Improved process for the preparation of 2,4,-diamino-5-(3',4',5'-trimethoxy-benzyl) pyrimidine
Inventor: BIRO IMRE
IPC: C07C255/53
Filed: 1982-06-24
Abstract: The invention relates to an improved process for the preparation of 2,4-diamino-5-(3',4',5'-trimethoxy-benzyl)-pyrimidine of the general formula I   <IMAGE>  by reacting a compound of the general formula II   <IMAGE> (wherein R is an alkyl group having 1-4 carbon atoms) with guanidine, which comprises preparing the said compound of the general formula II by reacting  alpha -(3,4,5-trimethoxy-benzal)- beta -methoxy-propionitrile of the formula III   <IMAGE> with ethylene glycol monoalkylether of the general formula IV HO-CH2-CH2-OR (IV> (wherein R as as stated above) in the presence of an alkali metal alkoxide at a temperature between 60 DEG  and 90 DEG and reacting the compound of the general formula II thus obtained - if desired without isolation - with guanidine in the presence of an alkanol having 4-8 carbon atoms. The advantage of the process is that it is economical and can be carried out with high yields even on industrial scale and provides a product of high purity. The compound of the formula I obtained is a known chemotherapeutical drug.
Patent GB-2108339-A (GB)
Title: Electric protective circuits
Inventor: MILLER LESLIE CHARLES
IPC: H02H3/33
Filed: 1982-07-01
Abstract: In an electric shock protection circuit for use with a load which may have permissible currents to earth (e.g. via the r.f. suppression filter F of a mobile transmitter), the core-balance transformer 3 includes both neutral and earth primary windings P3, P2, and a bypass shunt impedance (Z1) is connected between the output side of the neutral primary P3 and the input side of an the earth primary P2. Any filter current to earth point CE passes through the transformer via the extra primary (P2), to maintain current balance. Leakage to any other earth point (c) trips the circuit in the normal way. In the event of power neutral discontinuity, neutral current bypasses the transformer via impedance Z1. In the event of a power earth discontinuity, filter current is routed twice through the transformer (3), ie once through the extra primary (P3) via the impedance (21). Either event causes current imbalance and operation of the trip-switch (S). Further monitoring functions may be provided, by adding additional impedance shunts (Z2 to Z5) between primaries, and between primaries and circuit earth. <IMAGE>

Title: Improvements in or relating to sheeting
Inventor: EVANS JOHN EVES
IPC: F16B5/07
Filed: 1982-07-21
Abstract: Composite sheeting (26) is made up of a series of strips (28) of P.V.C. or other material interconnected by joint means (10). The joint means comprise interconnecting male and female portions (14, 12), conveniently of extruded P.V.C. The female joint portion (12) includes an elongated tubular member (12a), defining an inner opening, with an elongate slit (16) running along the length thereof. The opening is of generally circular cross-section with a number of longitudinal lobes (18) extending inwardly. A flange (20) extends outwardly from the tubular member (12a), located directly opposite the slit (16). The male joint portion (14) includes an elongate head portion (14a) of generally circular cross- section corresponding to that of the opening of the female joint portion, including a number of longitudinal slots (22) for cooperating with the lobes (18). A flange (24) extends outwardly from the head portion (14a) to pass through the slit (16) when the joint portions are interconnected. The joint portions may be connected and dismantled by a sliding section. The resulting sheeting (26) may be used, for example, for ground sheets for sports grounds and also for structures such as greenhouses, marquees, canopies, etc. The composite nature of the sheeting facilitates transport, handling and repair. <IMAGE>

Title: Testing of infra-red sensitive equipment
Inventor: MCEWEN DR ROGNVALD SUTHERLAND
IPC: F41J2/02
Filed: 1983-02-22
Abstract: To test I.R. sensitive equipment, e.g. a homing missile, a matrix of resistive units such as thick-film elements are connected via individual diodes between column and row conductors on a cooled substrate. The rows are scanned in sequence, and the levels of the voltages applied to the column conductors during the activation of each row determine the heat output of the elements along the row. The heat (I.R.) emission from the panel represents a changeable thermal image. The image may be selected by electrical control or by light on photosensitive elements, e.g. from a CRT. <IMAGE>
