Title: Stripping undesirable constituents from vegetable or animal oils - by tubular hydrolysis stage between contact reactor and expansion vessel
Inventor: SCHUMACHER HEINZ
IPC: C11B3/14
Filed: 1975-10-29
Abstract: Undesirable constituents are stripped of oil substances of vegetable or animal origin in a contact stage in which a distillation aid is at a high temp. and press. to reduce the boiling point of the constituents. A tubular hydrolysis stage at the discharge from the contact stage is followed by an expansion stage. This results in a better purificn. of the edible oils which have a longer shelf life and are free from oxygen cpds.

Title: Reversing switch installation for electrically driven toys - acts on super voltage impulses supplied by voltage doubling device
Inventor: MOODASCHL BERT
IPC: A63H19/24
Filed: 1975-12-05
Abstract: A reversing switch installation is for electrically driven toys. The installation includes a current supply unit connected to the domestic electric supply and providing AC for the electrically driven toys with a reversing installation acting on super-voltage impulses fitted on or in the toy vehicle.

Title: Flame effect yarn - is a semi-worsted made from mixture of long staple carrier sliver and short staple carded roving
Inventor: REININGER HERMANN
IPC: D02G3/34
Filed: 1976-10-20
Abstract: The mfg. process for an effect yarn uses a semi-worsted yarn formed from a long stapel carrier with short staple carded yarn of different colours, spun together to give a shimmering effect.

Title: Active gas detector - having wide operating temp. range and simple operation
Inventor: LOH JACK C
IPC: G01N27/12
Filed: 1977-08-29
Abstract: A gas detector comprises a helical coil connected to a d.c. power source for generating an electromagnetic field and radiant heat contacting and surrounding a thin walled tubular sleeve of active sensing material. The sleeve lies within the electromagnetic and heating fields of the coil and is of a material that supports an induced electric current at a predetermined temp. in response to a magnetic field. An electrode is placed within the sleeve, contacting its surface. When a current sensing element is connected between the electrode and one end of the coil an electromagnetic current is produced that is proportional to concn. of the gas to be detected in contact with the outer surface of the sleeve. The solid state device can be used over a wide temp. range. It is an active device, simpler to operate than passive devices requiring another potential across the sensing material.
