Title: Chlorine prodn. from ammonium chloride - pref. as integrated prodn. of chlorine and sodium carbonate from calcium carbonate
Inventor: ABRAHAM BERNARD M
IPC: C25C3/00
Filed: 1979-07-06
Abstract: Chlorine is produced by (i) heating NH4Cl to give NH3 and gaseous HCl; (ii) reacting the vapours with Cd, Zn or pref. Sn to give a metal chloride; and (iii) electrolysing the metal chloride in the presence of a molten salt electrolyte, to give Cl2 and the metal. This sequence can be used (claimed) in the integrated prodn. of Cl2 and Na2CO3, involving (a) heating CaCO3 to give CaO and CO2; (b) reacting CO2 with H2O, NH3 and NaCl to give NaHCO3 and NH4Cl; (c) heating the NaHCO3 to give H2O, CO2 and Na2CO3; (d) as stage (i) above; (e) as stage (ii), giving a metal chloride, NH3 and H2; (f) as stage (iii); (g) recycling the NH3 from stage (e) and the metal; (h) burning the H2 from stage (e) to give the heat necessary for the process. Cf. conventional prodn. of Cl2 and Na2CO3 (i.e. brine electrolysis and the Solvay process), this process has a reduced electrical requirement, does not require the use of a dimensionally stable anode, and does not produce CaCl2 with its attendant disposal problems.

Title: Individual rewinding of parallel-wound ends - with yarn tension controlling speed of positively-driven supply package
Inventor: BOCK GERHARD ING GRAD
IPC: B65H59/38
Filed: 1979-07-28
Abstract: In a machine on which parallel-wound yarns on a single package are sepd. and rewound as single ends, the supply package can be braked, or positively driven, by surface contact with a constant- speed drive roller at a speed which varies in relation to the tension in the yarn. Either the package or the drive roller has a conical shape, and the conical member can swivel around an axis perpendicular to the cone axis, allowing the point of contact between spool and roller to wander along the length of the cone to adjust the unwinding speed and maintain uniform yarn tension. The machine gives trouble-free sepn. of the yarns, in spite of variable and erratic adhesion between the ends.

Title: Electromagnetically operated mechanical brake for motor - has additional eccentric drive for releasing brake by hand
Inventor: BAUDISCH ERNST
IPC: F16D65/14
Filed: 1980-04-09
Abstract: The brake magnet (1,5) and armature are carried on the motor drive-end endplate. The armature carries a brake disc (7) which acts on the fan back (10) to give the braking effort. The brake is released by energising the magnet coil. Two bolts (13) penetrate through the disc and endplate and hook (14) into a tilting plate (11) located behind the bearing housing (2). Bolts and plate form part of the manual brake release. On the fan side the bolts are fitted with discs (18) which bear against the brake disc (7) to pull it off when the manual release is operated. Operation of the manual release is by an eccentric (12) which, when turned from the outside of the motor housing, tilts the plate (11) to give an axial movement of the bolts (13) in the required direction.

Title: Doppler radio direction finder - has multiple path filter and evaluates closely succeeding signals and near sources by switching bandwidth
Inventor: HENKEL BERNHARD
IPC: G01S3/54
Filed: 1980-04-18
Abstract: A radio direction finder, esp. a Doppler type for shipping, has an N-path narrow band filter operating with the summation method and overcomes the problems experienced with conventional devices in evaluating radio signals occurring within short time intervals of each other. Similar difficulties with signals from near sources are eliminated. The bandwidth of the N-path filter (3) can be switched to greater widths or the effective evaluation time of the location result processing stages to a predefined shorter value. The reduction in evaluation time can be carried out in the N-path filter via a switch (6) which discharges the low-pass elements. One or several discharge switches are used. These are operated cyclically by a timing circuit (7) of adjustable duty cycle.

Title: Automatic engine cut=out and starter - has control push=pull switches on throttle and clutch linkage, interlinked with speed sensor
Inventor: BECHEM ULRICH WILHELM
IPC: B60K26/04
Filed: 1980-12-06
Abstract: The pedal mounted switches stop the engine when the driver lifts his feet from the throttle pedal and the clutch pedal. This saves fuel when waiting at obstructions etc. To restart the engine the clutch pedal is fully depressed, with the starter solenoid switch located at the bottom of the clutch pedal travel. A failsafe circuit prevents starter operation when the engine speed is at or above idling speed. The failsafe circuit is operated in conjunction with the output from the alternator, as is the control circuit. The cut-out operates when both pedals are released and the vehicle stopped.
