Title: False signature detection system - is used for cheques and bills and incorporates key figure which is made to appear when cheque is dampened
IPC: D21H21/46
Filed: 1977-04-20
Abstract: The cheque false signature detection system uses marks and signatures written alternatively over several parts of the cheque. The marks and signatures are written either with indelible ink or with absorbant ink of similar colour. The signatory must write under his signature a key composed of figures 0 and 1 in indelible ink. the key number is determined from the positions of alternate successive marks written from the left of a cheque towards the right and from top to bottom. The key (20) is made unreadable by superposing spiral curves (21) in absorban ink. When the cheque is dampened it produces only on the parts written in absorbant ink a colour change and causes the true key figure to appear in dark indelible ink. The key figure is then compared with the positions of successive marks.

IPC: C23C18/16
Filed: 1977-07-13
Abstract: The electroless generation of metal coatings from aqueous metallisation baths is effected by means of an appliance having a working vessel for the metallisation bath and a centrifuge for separating solid particles. Below the bottom of the working vessel (1) there are arranged a drum centrifuge (2), a pipeline (3) from the bottom of the working vessel to the drum centrifuge and a peeler tube (4) for withdrawing the purified liquid. The peeler tube projects into the centrifuge at a point of high pressure and is connected via a return line (5) to the working vessel. The drum centrifuge is advantageously provided with an insert made of chemically and thermally resistant plastic material. The appliance is operated while circulating an aqueous metallisation bath, the solid components contained in the bath fluid being separated in said centrifuge. A drum centrifuge is employed. The bath fluid is allowed to flow into the drum centrifuge under its own weight, and the purified liquid is withdrawn from the drum centrifuge with the aid of a peeler tube at a point of high pressure and returned into the bath via a riser.
