Title: Sound recording and playback system for headphones - uses additional forehead loudspeaker and nose microphone in dummy head
Inventor: LENSING JOHANNES DIPL PHYS DR
IPC: H04R5/027
Filed: 1975-10-10
Abstract: The sound recording and replay system, for headphones, records sound using three microphones and replays it via three headphones. The microphones are located inside a dummy head: one inside each ear and one behind the nose in the nasal passages just behind the bridge of the nose. The loudspeakers for replay are located one over each ear and one flat against the listeners' forehead. This truly reproduces the auditory stimuli and the hall ambience, and avoids the impression that the sound is coming from behind.

Patent DE-2558104-A1 (DE)
Title: Hybrid magnetic hover and rail system - has wheels maintained in rail contact for static basic load accommodation
Inventor: GREBE OTTO DR ING
IPC: B61F9/00
Filed: 1975-12-22
Abstract: The dual rail transport support and guiding system uses the magnetic hover principle for high-speed travel, and a normal wheel and rail layout for low speeds or when stationary. Even at high speeds the wheels remain in contact with the rails, taking up the vehicle basic loading. The magnetic hover system serves only to regulate dynamic irregularities and oscillations in the course of travel. High-speed travel may involve an electrodynamic hover system on the zero flux principle, esp. with a broad gauge track using a symmetrical linear motor drive. Lower speeds involve a separate wheel drive in a normal track, with individually suspended wheels.

Title: Dough rolling machine - feeds rolls by endless belt pair with convergent gap and delivers in pair with parallel gap
Inventor: PROHASKA FRANZ ING
IPC: A21C3/06
Filed: 1976-01-28
Abstract: A dough rolling machine in which the kneaded lump of dough is first flattened and when would in a roll has ahead of the entry gap of the flattening rolls a pair of endless belt conveyors. These conveyors leave a converging gap between them so that the round lump of dough is precompressed before it reaches the roll stand. This machine can readily be inserted into a fully automatic production line for pastry. The serious injuries caused by accidents during a feeding of the rolls by hand are eliminated.

Patent DE-2637210-A1 (DE)
Title: Heat pump delayed action coolant stop valve - has pressure switch to open valve and thus initiate coolant circulation period for attached compressor
Inventor: KROELL ULRICH ING GRAD
IPC: F25B30/02
Filed: 1976-08-18
Abstract: The heat pump in a cooling cycle has a compressor which continued to run after the valve in the coolant circulation has closed. The compressor runs until the pressure on its suction side is reduced to approximately atmospheric. This increases the efficiency of the compressor lubricant, by keeping coolant from mixing with it. A relay is provided to hold the coolant valve closed for a time when the compressor starts again after a power failure. A pressure switch pref. ensures that, when the valve opens to initiate a period of coolant circulation, the compressor begins to run before coolant reaches it at high pressure. The same switch pref. switches off the compressor when the coolant pressure has fallen to approximately atmospheric.
Patent DE-2638428-A1 (DE)
Title: Alkaline effluent neutralisation - by mixing in nozzle with neutralising gas at specified pressure and vol. ratio
Inventor: CHAWLA JOGINDAR MOHAN DR ING
IPC: C02F3/12
Filed: 1976-08-26
Abstract: Industrial wastes with a high alkaline content are neutralised by mixing them with a gas such as CO2 in a nozzle. Their separate volumetric flow rates are such that the outflow velocity from the mixing chamber equals the characteristic sound velocity of the 2-phase mixt. The pressure of the mixt. is suddenly reduced on emerging from the chamber. If a non neutralizing gas was used, the mixt. now enters a neutralizing gas atmos. This procedure results in a uniform redn. of pH from say 14-7.5 or 2 with a much reduced amt. of gas and in a shorter time required for the reaction.
Patent DE-2641627-A1 (DE)
Title: Fertiliser contg. nitrogen, phosphorus, potassium and calcium nitrate - prepd. from cane sugar molasses or vinasse by neutralising, converting insoluble calcium cpds. to solubles and burning
Inventor: UTIKAL HANS DR
IPC: C05F5/00
Filed: 1976-09-16
Abstract: A fertiliser, obtd. from molasses or vinasse from cane sugar contains 0.5-6% N, 0.1-1.5% P, 5-20% K and 0.15-13.5% Ca(NO3)2. The fertiliser does not have the disadvantages of previous fertilisers from molasses or vinasse which were strongly acid and therefore destroyed cane sugar plantations: in a few years and had to be kept in acid-resistant steel tanks. The gypsum which can cause encrustation in tanks and pipes holding the fertiliser is removed or converted to a water soluble Ca cpd. The molasses or vinasse is neutralised to pH 5-8 (pref. 6.8) pref. using lime. Any insoluble Ca present as gypsum is converted to soluble Ca using e.g. NH4NO3 or Na2S2O3. The resulting mass is concd. to 50-90 (pref. 68%) dry materials and then burnt to give the fertiliser.

Title: Machine tool for internal thread cutting - has oscillating spindle to allow cutting edge to adapt to pitch of thread being cut
Inventor: BERTRAM FRIEDEL
IPC: B23G1/34
Filed: 1977-08-06
Abstract: The machine tool for cutting internal screw threads has a fixed outer housing with a top cover. The top cover has an eccentric stub shaft which supports a self-aligned bearing for the spindle. The spindle has spherical teeth cut in its upper end which mesh with pinions which in turn mesh with an internally toothed ring. When a bevel wheel is driven, the internally toothed ring drives the spindle so that it rotates about its own axis and at the same time oscillates about the centre of the spherical radius of the teeth. This compound motion enables the cutting tool fitted to the spindle to assume the correct angle to suit the pitch of the thread being cut.
