Patent DE-2546290-A1 (DE)
Title: Determination of chlorine in air - with the help of a silver chromate impregnated paper and prior removal of hydrogen sulphide and hydrogen cyanide from the gas
Inventor: LUEBKE DIRK ING GRAD
IPC: G01N31/22
Filed: 1975-10-16
Abstract: The parent application discloses a method of measuring traces of Cl gas in air by using a gas analysis unit with a paper impregnated with Ag2CrO4. The paper is sensitive to H2S and HCN which interferes with the reaction of HCl, HBr and HI from which the Cl concn. is calculated. The effect of H2S and HCN is eliminated by heating the gas, pref. to 1200 degrees K, and cooling the measuring gas before feeding the gas sample to the indicator paper analysis unit.

Title: Fusing lamp bulbs and frames - in a heating zone with uniform heating and cooling profile
Inventor: TOLNAI AGOSTON
IPC: H01K3/12
Filed: 1975-10-15
Abstract: In the fusion of rotationally symmetrical glass bodies, individual components such as the bulbs and frames of incandescent lamps and other products of vacuum technology, the glass bodies to be joined are held in specific positions, set into rotation, heated by means of burner jet, supplied with fuel gas/or mixture or if necessary oxygen, formed and fused together. The glass bodies held part at specific distance and set in rotation are advanced continuously along a pref. linear heating zone of pre-determined length at pre-determined speed, the heating zone being formed by a series of locally fixed glass flames on one side of the transport path, and a heat storage and radiating wall fixed opposite. Risk of constant breakage is avoided and increased and stabilised output is obtd. by uniform heating and cooling of the lamp bulbs and frames.

IPC: F02D21/08
Filed: 1975-10-23
Abstract: The connecting pipe (2, 3) between the induction manifold and the pneumatic exhaust gas feed back valve (4) contains a regulator valve (1). The regulator valve (1) is actuated by a cam (29) fixed to the accelerator throttle valve shaft (30), so that at slow running and at full throttle speeds when no exhaust feed back is desired, the depression source is interrupted.

Title: Radio network emergency caller identification - uses random time staggering to prevent mutual blotting out of simultaneous emergency calls
Inventor: VOGT WILLI DIPL ING
IPC: H04B1/3827
Filed: 1976-04-13
Abstract: A radio transmitter/receiver is for a network with a number of stations working with a central station on a common channel. an emergency cally device provides for the transmission of an emergency call from any station on pressing an emergency button, which ensures identification of the callers at the central station if more than one station radiates an emergency call at the same time. Each station automatically calls an emergency signal interrupted at intervals by its call sign. to facilitate identification of received call signs at the centre the time between call-signs identification signals is made variable to prevent permanent overlap. this may be effected by a random signal generator in the form of a shift register with feedback, which is automatically switched in on pressing the emergency button.

Title: Measurement and control of output torque of DC motor shaft - by measuring armature current and multiplying by constant to represent max. torque developed
Inventor: KRISHNAN L BALA DIPL ING
IPC: G01L3/00
Filed: 1977-01-26
Abstract: The measurement and control arrangement is for the output torque of a d.c. motor shaft. The armature current is measured and multiplied by a constant. A signal multiplied by this constant corresponds to the total maximum torque developed by the motor. Motor angular speed is measured, and a signal is differentiated w.r.t. time. The derivative signal is multiplied by a different constant, so that the resultant signal corresponds to the torque necessary for the motor acceleration. The two signals are subtracted from each other, and the difference signal displayed or used for control purposes.
