Title: Hydrochloric acid effluent treatment - by lime neutralization and sulphuric and admixture to remove calcium sulphite
IPC: C02F9/00
Filed: 1973-11-12
Abstract: Industrial effluents from metal rinsing baths, containing hydrochloric acid, following the pickling operation before hot-dip galvanizing are first neutralized by adding lime. Sulphuric acid is added to the resulting CaCl2 solution to produce CaSO4 and a strongly diluted HCl solution. The latter is recycled into the process circuit. This eliminates the formation of effluents with a high content of salts (CaCl, NaCl) which are difficult to treat and cause serious pollution of the waste water channels. The by-products can be sold for the manufacture of paper and the process needs little make-up water.

The recognition signals generated by the control unti are in code form. If a receiver in operation receives a signal from a remote station then the associated symbols will be omitted from the recognition signals. The control unit has a separate sequence selector for each receiver.

Title: Insulated waterproof roof covering - uses arched tiles resting on concave waterproof strips and grooved thermal insulating layer on woodwork
IPC: E04B7/22
Filed: 1975-06-30

Title: Signal processing or transmitting systems - including teleprinters have device for errors correction during keying-in of symbol (NL060576)
IPC: H04L13/08
Filed: 1975-11-04
Abstract: A delay unit is inserted between the input unit coder and the recording unit or transmission unit which delays the signal transmission for up to several seconds. When there is an error a special key on the keyboard is operated by the user of the machine during the delay period and this may activate a logic switching arrangement, whose output signals prevent the transmission of the symbol. They may also prevent recording and may erase symbols which are stored in the delay unit. The delay period is long enough to enable the user of the machine to spot any mistake.

Title: Plethysmograph for detecting thromboses - has two current generators feeding into impedance formed by resistance of mercury gauge
Inventor: MICHAUX B
IPC: A61B5/103
Filed: 1975-12-19
Abstract: The plethysmograph is used to measure arterial and veinous expansion and detect thromboses. It comprises a Wien bridge oscillator supplying two current generators feeding into a mercury gauge. The voltages due to the resistance of the gauge and a potentiometer are rectified and amplified. These are compared in a differential amplifier and coupled into a low-pass filter. The resulting voltage is detected by a galvanometer connected through a switch to give a direct reading. Another switch permits selection of arterial or veinous observation by either passing through a high-pass filter to a recorder or by short-circuiting this.
Patent FR-2298224-A1 (FR)
Title: Controlled rectifier for motor regulation - comprising several bridges in series on DC side has single primary and three secondaries in transformer on AC side
Inventor: TSUBOI TAKASHI
IPC: H01F29/00
Filed: 1976-01-15
Abstract: The application is principally to the control of traction motors where smooth acceleration is required. The rectifier (2) comprises typically three bridges (21, 22, 23) connected in series on the d.c. side and supplied from three separate secondary windings (12, 13, 14) on the transformer (1) which has a single primary (11). The controlled bridges are switched sequentially, one to give a ramp and the remainder in blocks to build up a steadily rising voltage across the motor (3). To avoid sudden current pulses the block is not switched in until the ramp voltage, plus any block already in, is slightly higher than the incoming block voltage. The voltage drop due to commutation from the outgoing rectifiers to the incoming one is thus compensated.

Patent FR-2345762-A1 (FR)
Title: Chopper circuit acting as DC converter - uses AC source and has frequency limitation and load regulation
Inventor: RILLY GERARD
IPC: H02M3/335
Filed: 1976-03-26
Abstract: The principal application is in the power supplies for television receivers equipped with solid state circuitry. Choppers acting as power converters normally operate in a manner similar to a blocking oscillator. The frequency changes depending on load and the synchronisation with the line scanner are thus problematic. The problem may be substantially overcome by placing a damping element between the switching transistor and the transformer primary winding. This damper comprises a diode with the same current flow direction as the transistor, and a parallel connected resistor. The damper counteracts the switching effects in the transformer secondary windings and helps to inhibit self oscillation.
