Title: AFC circuit for receiver oscillator - has circuit responding to noise which compensates discriminator output voltage shift
Inventor: WENDT FRIEDRICH-KARL
IPC: H04N5/50
Filed: 1976-12-21

Patent DE-2712939-A1 (DE)
Title: Positional error detector for coordinate measuring instruments - uses twin light beams to indicate deviation from Z-axis
Inventor: FROHNE HEINRICH PROF DR ING
IPC: G01B11/26
Filed: 1977-03-24
Abstract: The positional error detector for coordinate measuring machines detects the division of a feeler arm from the theoretical Z axis of the coordinate gauge instrument. The spindle carrying the feeler head with a ball point is supported in a bearing in the Y carriage. A light beam is transmitted from a source attached to the carriage and received at a photodiode attached to the feeler head. A similar source is attached to the head and is detected by a diode on the Y carriage. When the feeler spindle is extended outwards along the theoretical Z axis, any deviation form the latter due to inaccuracies in the bearing etc., cause the respective light spots to move from the centre datum positions on the sensor elements. The output signals thus derived are used to determine correction coordinates for the measuring head.

Title: Active wideband signal isolator - contains circuit used to generate antiphase cancelling signal for reverse path while permitting forward transmission
Inventor: IRONS RONALD EDWARD
IPC: H03H11/38
Filed: 1977-03-31
Abstract: An active wide band isolator is used. IT is for general application with a circuit (2,4) to couple a signal from a first input (26) to an output (28) and a reverse signal from a terminal (28) to a terminal (26). There are circuits (6,8,12,24) to isolate the input terminal (26) from the output terminal (28) in relation to the reverse signal. They are able to develop an inverse cancellation signal with approximately 180 deg. phase shift. Circuits are also provided to combine the cancellation signal with the reverse signal so as to prevent the appearance of both signals at the input (26).

Abstract: (I) is prepd. by oxychlorination of ethylene using HCl gas and a gas contg. molecular O2, pref. air, in the gas place at elevated temp. and in the presence of a fluidised bed catalyst of cuprous chloride on a support. The reaction gases are cooled under pressure in two condensation stages. The condensed 1,2-dichloroethane is then removed and the major part of the unconverted starting gases and the inert gases are recycled and in a third condensation stage the reaction gases are cooled under pressure at 5-18 degrees C such that the amt. of 1,2-dichlorethane in the recycled gas remains between 0.5 ad 3 (0.5-1.5) vol % and the recycled gas is mixed directly above the reactor with the amt. of O2 (pure) needed to replace the O2 used up, and to re-establish the O2 strength at 12-25(15-21) vol.%. (I) is prepd. economically in improved yield and more economically. Process is variable as required. The activity of the catalyst can be varied by means of the supply of fresh oxygen supplied to replace that used up in the reaction so that a space time yield of 10-100% can be obtd. as required. Reaction is safer with less explosion hazard.

Title: Automatic control for electronic flash - operates with flash duration varied in steps to conserve battery power
Inventor: PROCHNOW CLAUS ING GRAD
IPC: G03B15/05
Filed: 1977-09-22
Abstract: The control panel(1) for the electronic flash has a simple slider to set the film speed and object distance. It displays the flash guide number and exposure details. The slider also operates a stepped control for the charging level of the main capacitor to conserve battery power. For e.g. close-up flash exposures, a low flash charge is used and the capacitor is not charged up to its full voltage. The capacitor is charged so that it can adequately cope with the set exposure and does not waste any excess charge.
Patent DE-2746582-A1 (DE)
Inventor: MANI DIETER
IPC: G07C9/00
Filed: 1977-10-15
Abstract: The device has a plurality of rotary decade switches (I, II, III) for specifying a code word, a rotary decade switch (7) and a push-button switch (6) for entering the code word and an evaluation circuit with a plurality of flip flops (2, 3, 4) which compare the specified code word with the entered codeword and, when the two coincide, deactivate the alarm system. The rotary decade switches (I, II, III) for specifying the code word are connected to the flip flops (2, 3, 4) which are connected to one another and to an acknowledgement flip flop (5) in such a way that after the code word has been entered, the acknowledgement flip flop (5) activates a transistor (8) which is connected to it and which brings about the switching off of the alarm system. The code is rejected by the entry of "zero" or any desired number. The evaluation circuit also has two timing elements (16, 19). The entry of numerals which are not contained in the code word blocks the electronics for a specific time. The time for the entry of the code word is also restricted to a specific period. This device is very simple and nevertheless provides a high degree of security. <IMAGE>
