Patent EP-0066180-A3 (EP)
IPC: G08C23/04
Filed: 1982-05-18
Abstract: The invention provides a transceiver (10) for bidirection­
al optical communication between two devices. A first output 
signal from the first device (12) is input to the transceiver. 
Using parallel optical data links (16, 18), an optical signal is 
generated (17, 19) in response to the first signal and is 
detected by a pair of light sensitive devices which cause a 
second signal, representative of the first signal, to be 
generated. The second signal is then conducted to the input 
terminal of the second device (20). In an alternate mode of 
operation, the transceiver receives a third signal from the 
second device. Using series optical data links (26, 28; 30, 32), 
optical signals (27, 34) are generated in response to the third 
signal and are detected by light sensitive devices. These light 
sensitive devices cause a fourth signal (35), representative of 
the third signal, to be generated which is then conducted to 
the input terminal of the first device. A control circuit (24, 36, 
38) cooperates with the parallel and series optical links to 
enable one and inhibit the other dependent upon whether a 
signal is to be communicated to the second device from the 
first device, or to the first device from the second device.

Title: A method and a device for pretreating non-ferrous metal for plastic deformation
IPC: C23G3/00
Filed: 1982-09-08
Abstract: The invention relates to the pretreatment of ductile non-ferrous metal to be deformed in a continuous plastic deforming device (20) in which the surface parts of the metal to be deformed do not substantially form surface parts of the metal after said deformation. Known methods of pretreatment include scaling off of thin surface layers and pickling e.g in baths and coiling or storing the metal thereafter before feeding to the deforming device. Such methods have disadvantages in view of energy, waste of material and, in many cases, in still having some surface contamination on the metal entering the deforming device. To avoid such disadvantages, the invention proposes to spray the metal with a deoxidation and cleaning agent in one throughgoing operation directly while it is moving to the deforming device and continuously and synchronously therewith. Spraying is done by directing forceful jets of the liquid onto the moving metal surface. The spraying agent is a strong alkali and for some types of alloys there is a further spraying step using an acid such as a strong nitric acid solution in water. The metal is thereupon, while moving on to the deforming device, rinsed with water and dried.

Abstract: Disclosed is a number controlled, modulated, oscillator 
employing a modulation selector for receiving a digital number 
for use for frequency modulation or for phase modulation, a 
tuning network for receiving another digital number in a 
variety of forms, and a frequency modulator for adding the 
value of the modulation selector number to that of the tuning 
network number. Also, the oscillator employs a phase accumu­
lator for adding the value of the frequency modulator sum to 
that of a number already stored in the phase accumulator and 
replacing the stored number with the phase accumulator sum at 
each of a series of times specified by a clocking signal. 
Further, the oscillator employs a phase modulator for adding 
the value of the number stored in the phase accumulator to 
that of the modulation selector number and an output selector 
developing the 1's compliment of the phase modulator sum and 
for selecting either the phase modulator sum or the compli­
mented number. Finally, the oscillator employs a waveform map 
for storing a quantity of amplitude numbers and for retrieving 
the number stored at the location addressed by the (modulated) 
phase accumulator selected number, a digital multiplier for 
receiving a number and for multiplying the value of the 
received number by that of the retrieved number, and a digit­
al-to-analog converter for developing a signal having, as an 
amplitude, the multiplier product.

mount is supported at three spaced apart locations by 
respective first, second and third supports, each adja­
cent to a respective one of the test points. These
