Patent EP-0447977-A1 (EP)
Inventor: GOERMAR GERHARD DR
IPC: C07C37/52
Filed: 1991-03-15
Abstract: The objective is a simple and economical preparation of p-alkylcalix[4]arenes of the general formula I <IMAGE>  where n is 4. The compounds are prepared from a pre-condensation product prepared from p-alkylphenol and formaldehyde, or from p-tert-alkylcalix[8]arenes or from a mixture of p-alkylphenol and paraformaldehyde, in each case in the presence of alkali metal hydroxides as catalyst, in a mixture of straight-chain hydrocarbons having a chain length of C11 to C20 at 217 to 257 DEG C. The p-alkylcalix[4]arenes are isolated directly from the reaction batch in well-crystallised form. The process is particularly suitable for the preparation of p-tert-butylcalix[4]arene (formula I, R = t-C4H9, n = 4) and p-tert-amylcalix[4]arene (formula I, R = t-C5H11, n = 4). The compounds prepared according to the invention can be used for metal ion extraction or for ion-sensitive electrodes, as stabilisers for polymer materials and as starting material for the synthesis of calix[4]arene derivatives.

Abstract: A mode changing over mechanism (71) for a tape player which can change over the mode of operation of the tape recorder with a simple structure and can be constructed in a small size and thickness at a low cost. The mechanism comprises a direction slider (72) movable among normal and reverse mode positions and a stopping position, a trigger member (104) having an engaging portion movable between arresting and non-arresting positions, and a rotatable cam gear (84) having a cam section having normal and reverse mode pressing faces for pressing a control portion of the direction slider in the opposite directions. When the engaging portion is at the arresting position, the cam gear is inhibited from rotating at a position when a play mode or a stop mode is established. When the engaging portion is moved once to the non-arresting position in a stop mode, the normal mode pressing face (93) presses the control portion to move the direction slider to the normal mode position, but when movement of the engaging portion to the non-arresting position is performed twice at a predetermined interval of time, the reverse mode pressing face (94) presses the control portion to move the direction slider to the reverse mode position.

Abstract: A method for preparing a lithographic printing plate comprising the steps of imagewise exposing, to light, a negative-working presensitized plate for use in making a lithographic printing plate which comprises a substrate provided thereon with a light-sensitive layer comprising an aromatic diazonium compound having at least one member selected from the group consisting of carboxyl groups, phenolic hydroxyl groups, sulfonic acid residues, sulfinic acid residues and phosphorus atom-containing oxyacid residues and developing the imagewise exposed presensitized plate with a developer which comprises an aqueous solution of an alkali metal or ammonium silicate having a ratio: [SiO₂]/[M], wherein [SiO₂] and [M] represent the molar concentrations of SiO₂ and the alkali metal or ammonia in the developer respectively, ranging from 0.15 to 0.75 and an SiO₂ content ranging from 1.0 to 4.0% by weight on the basis of the total weight of the developer to remove the unexposed portion of the light-sensitive layer. 
     The method for preparing lithographic printing plate makes it possible to treat both negative- and positive-working presensitized plates with a single developer and a single automatic developing machine and can provide a lithographic printing plate having excellent printing durability and free of background contamination. Moreover, the replenisher for developer of the present invention permits repeated development process over a long time period without deteriorating the developability thereof and makes it possible to perform developing process without accompanying any formation of deposits due to the light-sensitive resin components at the bottom of a developing bath.
