Title: Non pressure type electric water heater - has pressure relief valve acting both ways between inlet and outlet
Inventor: HUSSLEIN JULIUS
IPC: F24H9/20
Filed: 1973-04-05
Abstract: The heater consists of a water container with an electric heating element within it and a connection to the water supply main. A pipe with an open top near the top of the container leads to the outflow. When the tap in the cold water supply connection is opened water flows into the container and displaces hot water through the open top of the outflow pipe. A cross pipe connects the supply and outflow pipes and contains a pressure relief valve. This has two seats with a central spring so arranged that it will open in either direction according to which side an excess pressure builds up on. In either case the discharged water is taken to the outflow so that it does not cause a nuisance.

Use of materials contg. modified fibres, which limit the pattern obtainable to that of the different fibres used in the carpet mfr., is not essential, although these can be used as addnl. variants. The reserving agent is pref. a metal oxide.
Patent DE-2420856-A1 (DE)
Title: Impulse sparking resistance butt welding - for large tubes and requiring relatively low electric power
Inventor: LEBEDEW WLADIMIR KONSTANTINOWI
IPC: B23K11/04

Title: A.M. carrier transmission method - uses signals which are modulated on bunched signal channels and transmitted through optical fibres
Inventor: RALL BERNHARD DIPL ING
IPC: H04B10/00
Filed: 1974-05-02
Abstract: Pulse frequency modulation is used for transmission of analogue signals. A voltage controlled oscillator is used in the transmitter which has limited output amplitude, and which is connected to the light producing device at the end of the glass fibre line. The pulse frequency modulated signal is reconverted by the light receiver and is applied to a phase controlled loop consisting of connected in cascade phase shifter, low-pass filter and a voltage controlled oscillator. The pulse frequency modulated signal is applied to one input of a phase comparator and the voltage controlled oscillator output is applied to its other input; the low-pass filter output signal is the demodulated frequency modulated signal.

Title: Coconut flakes prepn - with coconut milk, oil and proteins as byprods
Inventor: FORSON WILLIAM
IPC: A23L25/00
Filed: 1974-05-10
Abstract: The coconuts are pierced to extract the liq. which contains 5% of dry extract; this has a very pleasant taste and is rich in vitamins and mineral salts which are lost in the conventional prepn. of desiccated coconut. The emptied nuts are autoclaved to remove the fibres and separate the nut from the shell, which is used as a valuable fuel, either directly or after transformation into charcoal. The brown epidermis is removed by hand with knives; this is dried to give a 2nd. grade copra. The nut is finely ground to obtain whole coconut milk and a first press cake, after treatment in a suitable oil-press. The press cake is mixed with the liq., drained from the nuts after piercing, and with pure water; after pressing, whole milk and a second press are obtd. The milk is super-centrifuged to obtain a cream which is dehydrated to sep. the virgin oil from the proteins. The creamed milk, the press cakes and the proteins can be mixed with an anti-oxidant and a thickener to form a fine paste; this is dried as a thin film on a drum and converted into flakes.

Title: Sodium acetate trihydrate used for heat storage - in form of undercooled melt releasing heat upon crystal nucleation
Inventor: ROETHER ULRICH DIPL CHEM DR
IPC: F28D20/02
Filed: 1974-10-12
Abstract: Heat storage in the form of the latent energy of an undercooled molten salt is improved by using sodium acetate trihydrate as an energy-storing medium. The salt is heated and melted by means of an off-peak electrical heater; it is then cooled to a temp. below its m.pt. (58 degrees C). The crystallisation (and the resulting energy release) is effected by introduction of crystallisation nuclei; this can be carried out manually or by a thermostat mechanism. Space-heating installations, or heating pads or the like, can be economically operated; 1 K W h. can be stored in 18kg. of molten salt. There is practically no energy loss. The release of the energy is effected rapidly. The system is not sensitive to mechanical disturbances or chemical contamination. An esp. advantageous application is the heating of a motor-car before start in the winner.
