Title: Hard brittle surface engraving system - uses tip of vibrating needle at right angles to surface
IPC: B44B3/00
Filed: 1977-06-10
Abstract: The system is for engraving a hard brittle surface, partic. glass. The point of a vibrating needle is applied at right angles or nearly so to the surface, and moved over it to the desired pattern. vibration frequency can be 50 Hz, and there can be a portable housing (1) contg. an electric motor, which causes a needle holder to vibrate. The motor stator can be fixed in the housing, while the holder is coupled to the armature, which can be of the vibratory type. Alternatively, it can be driven via an eccentric form a rotary armature. As a further alternative, the holder can be fixed to the stator, while the armature drives an unbalanced weight. The needle (6) can have a hardened steel point.

Filed: 1978-01-17
Abstract: A hardenable material consists of a polyene and a polythiol where the total of the thiol-reactive C=C bonds in the polyene, and the thiol groups in the polythiol is >4. The polyene or the polythiol is a new substd. hydantoin deriv. of formula (I): where m and n are is not 1, m+n=2-22; and D is an organic gp. contg. is not 1 thiol-reactive C=C unsatd. group or is not 1 SH group. (I) are esp. prepd. by reacting I (D=H) with an unsatd. isocyanate, or with an unsatd. carboxylic -acid, to prepare the polythiols. Use of the matl. as a coating compsn. esp. on wires, is claimed. Other uses include adhesives, films, moulding compsns. printing plates, and Ag-free photographic materials. The hardened material has better resistance to high temp., e.g. when used as electrical insulation, and also resists acid and alkali. The matl. is flexible and has high elongation at break.

Title: Automatic system for measurement-control of cathodic protection - incorporates timer so that potential difference measurement is made instantly cathode current is switched out
IPC: C23F13/04
Filed: 1978-04-19
Abstract: The potential difference between a reference electrode and the surface of the object to be protected in a cathodic protection system is automatically measured by means of a system which incorporates time switches for switching out the cathode current thereby eliminating the electrolyte voltage drop error at the time of the measurement. The system consists of an amplifier for amplifying the voltage at the reference electrode, a timing device for switching off the feed rectifier for short periods whilst leaving it switched in for long periods, a memory which stores the "out" voltage measured during the switched out period, a selector circuit for comparing the incoming voltage signal from several reference electrodes and selecting the lowest value which is then used for automatic regulation and a differential amplifier which compares the selected measured value with a reference voltage and gives no signal if the measured value is equal to or greater than the reference value. The system enables the cathodic protection system to be automatically regulated on the basis of a potential difference measured when no current is flowing eliminating the IR error. Since the measurement is carried out almost instantly the current is switched out, the error due to depolarisation is also avoided.

Patent NL-9200397-A (NL)
IPC: G11B20/10
Filed: 1992-03-04
Abstract: A device is described for recording information which is applied at a bit frequency which is lower than that at which it is recorded. The difference in bit frequency is compensated by an input buffer memory (6). Recording is interrupted each time until sufficient information is present in the input buffer memory (6) so as to record a subsequent packet of information. During the recording interruptions the recorded information pattern is read. To obtain an indication signal Vinc indicating the recording quality, the read signal Vl is analyzed by means of an analysis circuit (11). The indication signal is used to adapt the setting of the write parameters. Based on this indication signal, a re-recording operation can be initiated. <IMAGE>
