Title: Method for determining bearings - has radio direction finder in which LF frequency phase provides information giving bearing
Inventor: DERING ADAM DR
IPC: G01S3/04
Filed: 1975-06-25
Abstract: The low frequency voltage is delivered by the direction finder demodulator systme, and the phase of this voltage is shifted by a low frequency phase shifter (3) by an angle equal to the bearing to be determined and the low frequency voltage (A), containing the information on the bearing, is then applied to the direction finder measurement system (4). The low frequency phase shifter (3) is supplied only during direction finding. a drive system using gearwheels (5) connects the low frequency phase shifter (3) to a slave compass (6). A switch (2) connects the demodulator system either with the low frequency phase shifter or with the direction finder measurement system.

Title: (1,2)-Dichloroethane prodn. from ethylene and chlorine - continuously in liq. phase with control of catalyst concn. in circulating liq.
Inventor: OPITZ WOLFGANG DR
IPC: C07C17/02
Filed: 1975-09-10
Abstract: Continuous prodn. is by liq. phase reaction of ethylene and Cl2 in an organic solvent contg. a chlorination catalyst dissolved therein. The reaction mixt. is circulated continuously through a reaction zone heated to 20-60 degrees C and a heat-exchanger to remove heat of reaction, fresh ethylene and Cl2 being added continuously to the circulating liquid and 1,2-Dichloroethane being withdrawn. A given amt. of catalyst is maintained in the circulating liquid, by returning a portion of the circulating liquid through a zone contg. the chlorination catalyst and into the reaction zone and by continually passing the circulating liquid into an analyser in order to establish the catalyst concn. The value found is then electronically controlled in the portion of the circulating liquid flowing through the catalyst zone by means of an impulse transformer such that too high a catalyst concn. in the circulating liquid is suppressed and reversed.

Title: Boat hull of GRP and foam core sandwich - made by winding round mould and sectioning for removal
Inventor: HOLTOM GERALD HERBERT
IPC: B32B5/24
Filed: 1976-05-24
Abstract: Boat hull or other hollow article e.g. pipe or container, of sandwich wall construction, is made or an internal mould by winding layers of lay-up matl. completely round the mould. An inner layer of resin impregnated fibre is followed by a core layer of synthetic foam matl. and an outer layer of resin impregnated fibre to complete the sandwich.
