Abstract: The furan derivatives have the formula 
<IMAGE>
 in which x<1> and x<2> are identical or different and represent H, alkyl, alkenyl, aryl, halogen, NO2 or CN. In the formula I, n can be 0 or 1. In the case of n = 0, A is, for example, -CH2OR<1> (where R<1> is, for example, H, alkyl or aryl), 
<IMAGE>
 in the case of n = 1, A denotes, for example, -CH=N-Z-N=CH-, 
<IMAGE>
 When compounds of the type  n = 0 are prepared, the hydroxymethyl group of 5-hydroxymethylfurfural (HMF) is first converted into a derivative and the aldehyde group is reacted with malonitrile, or, alternatively, the aldehyde group is initially converted into a derivative, the hydroxymethyl group is then oxidised and reacted with malonitrile. The compounds of the type n = 1 are prepared by either condensing two substituted or unsubstituted 5-hydroxymethylfurfural molecules first with one molecule containing at least two NH2 groups and, after oxidation of the two hydroxymethyl groups with malonitrile or, alternatively, first two hydroxymethylfurfural molecules are linked with elimination of water and the reaction with0 the malonitrile is then carried out, or two substituted or unsubstituted hydroxymethylfurfurals are linked via a two-carbon bridge by a benzoin addition reaction, the hydroxymethyl groups on the furan ring are then oxidised and reacted with malonitrile. The furan derivatives can be used directly or in the form of their cycloaddition products for various applications in the electrooptical sector, for example for the production of optical data recording systems or organic electrically conducting substances or electron transfer catalysts.

Abstract: An angle coupling structure for knockdown cabinets includes an angle coupling (100), a plurality of connectible sections (2), and a plurality of securing aid (3). Within each of the connectible section, an elongate chamber (21) is formed to receive a connecting rod projecting (11) from the angle coupling (100) and an elongate recess (22) is formed generally below the elongate chamber to receive one of the securing aids (3) and permitting the same to slidably move therein. An elongate slot (23) is formed on the wall between the chamber and the recess. While a screw (12) is put through the hole preformed on the securing aid, it may pass the elongate slot to screw into the hole formed on the connecting rod precisely due to the adjustable position of the securing aid. The connectible sections, angle coupling, and the securing aids are thus joined together tightly.

Granted: 1991-09-11
Abstract: A coupling fitting for making joints in reinfocing bars or wires for structural concrete aims to provide a mechanical strength of the coupling virtually equal to the full design strength whilst providing the ability to increase the strength upto and beyond ultimate tensile strength of the rebar by the addition of resin. To that end the coupling comprises a sleeve (1) for fitting in spaced relation around adjacent portions of rebars to be joined and having positively adjustable engagers (3) threaded through the wall of the sleeve, and profiled engagers (17) to engage said portions. The engagers serve for centring the rebars and the profiling serves to provide a key preferably with both the sleeve and the rebar. It is also preferred to have the positively adjustable engagers configured to bite into the rebars. The spaced relation affords provision for introducing settable resin.

Abstract: An electromagnetic relay with a return spring is described, where the relay consists of a solenoid coil with a movable armature as the drive and a contact spring assembly, and there is an actuating rod that starts from one end of the armature and engages with spiral springs by means of catches for actuation of the contact, whereby the return spring at the other end of the actuating rod returns the contact spring assembly to home position. In order to achieve a significant reduction in force with the contact spring assembly in actuating the relay, the reset spring here is designed as a top dead center spring such that when the relay is driven against the return spring, the force needed to bend the spring is reduced.
