Title: Selective alcoholysis of fats - under controlled low temps for edible cold-stable unsatd oil prodn
IPC: C11C3/10
Filed: 1971-07-21
Abstract: Controlled selective alcoholysis of glyceride fat/s to edible oils, e.g. margarine and shortening, and industrial oils, takes place by introducing the fat and an alcoholysis catalyst, and opt. solvent, into a reactor or a first reactor of a series under temp. conditions such that no crystals nuclei of glycerides other than GS3 (trisatd. glycerides) are formed; carrying out selective crystallisation of GS3 at temp. still kept low up to higher degrees of conversion, going through a GS2U (desatd. Triglyceride) crystal phase, opt. after the selective GS3-phase, and finally deactivating the catalyst and washing out modified fat.

Inventor: PETERS PETER
IPC: C05F3/00
Filed: 1972-10-17
Abstract: Pathogenic germs are killed and odours reduced or eliminated in liqs. contg. org. substances (e.g. liq manure liq. faeces or other liqs to be broken down for the purpose of biological compositing or disinfection) by (a) conducting oxygen-enriched gas into the liq. while stirring in a receptacle, so that a foam is formed and collects on the liq. surface, and (b) also introducing the foam into the liq. in addn. to the oxygen-enriched gas. The foam formed on the liq. surface has a relatively finely porous structure and the bubbles of which it is composed are relatively stable. When this foam is introduced into the liq. these bubbles pass relatively slowly through the liq. ensuring prolonged contact of the liq. with oxygen contd. in the bubbles and improving oxidn of the liq.

Title: Side-cutting wire nippers - material thickness of bottom jaw greater than top where blades join them
Inventor: ODENTHAL SEN HANS
IPC: B26B17/00
Filed: 1973-07-04
Abstract: The blade of the top jaw is flush with it, while that of the bottom jaw is offset from it.

Title: Ball bearing mounted door hinge pin - has elliptical rotating separator for releasing loads on bearing for dismantling purposes
Inventor: PUCHTLER FRIEDRICH
IPC: E05D7/10
Filed: 1973-10-06
Abstract: The door hinge pin has a load releasing plug which is rotated for bringing the ball bearing out of contact with the seat so that the door can be removed readily from its hinges. The rotating element has an elliptical cross section in contact with the seats of the ball bearing. These ball bearings are in retracted position so that the hinge can now be taken apart. On refitting the central plug is rotated so that its major diameter pushes the plug and the ball bearings into engagement with the bearing seats in the other half of the hinge. Once the ball bearings have engaged the door is again operational. The central actuating plug is not subject to wear and unskilled persons can readily fit and dismantle the door.

Title: Circuit for reducing interfering oscillations in telephone cables - has DC blocking capacitor in pilot strand connected at remove end from amplifier
Inventor: BAUM WALTER DIPL PHYS
IPC: H04B3/28
Filed: 1974-02-09
Abstract: The circuit reduces interfering oscillations in the active reduction circuit in telephone transmission cables. It will separate and remove the direct current component and these oscillations are either suppressed or pushed outside the working range of the amplifier. The pilot strand will also carry an interfering direct current component. This is blocked at the input of the amplifier by a capacitor and diverted through a separate secondary winding of the coupling transformer and a resistor. The capacitance is connected to the end of the pilot strand remote from the amplifier. The a.c. component is taken from the pilot strand, amplified, and fed to the primary of the coupling transformer.

Title: Battery operated radio receiver - has transistor switch controlled by pulses from astable multivibrator
Inventor: BITAR OMAR DIPL ING
IPC: H04B1/16
Filed: 1974-06-01
Abstract: The multivibrator is permanently connected to the battery, and the keying ratio of its pulses is such that periods when the receiver is on are much shorter than periods when it is off. A holding circuit with an SC component responds to the reception of an h.f. carrier and holds the multivibrator in a state in which the receiver is on. It releases the multivibrator when the carrier disappears. Multivibrator and holding circuit consists of NAND circuits based on active components, combined into a monolithic integrated unit. Space requirements and power consumption are reduced by this simplified arrangement.

Title: Latch system for cylindrical lock - two opposed symmetrical sliders ensure two keys required to lock and unlock
Inventor: BOSSERT HORST WERNER
IPC: E05B29/06
Filed: 1974-06-05
Abstract: The cylinder lock designed for switch gear so as to operate an EITHER or OR system and which requires to be locked and unlocked by two different keys held by two persons, has two different sliders (4, 5) held in the engaged position in grooves (7, 8) through the body (1) by a spring (6). These sliders are interchangeable, and have curved edges facing in opposite directions, and only one is disengaged by the first key, so rotation takes place in only one direction. Thus to rotate the cylinder (3) which holds them, in the opposite direction, a second key which engages the second slider must be inserted. Curved filling pieces can be inserted in the remaining grooves (8).
