Title: Nickel allyl complex - used as oligomerisation or polymerisation catalyst of alkene(s) and diene(s)
Inventor: TKATCHENKO IGOR
IPC: C07C2/36
Filed: 1980-08-08
Abstract: Ni allyl complexes of formula (I) are new. R1-5 are each H, alkyl, aryl or ERn, where E is a heteroatom such as N, S, O and R is 1 or 2 (n is 1,2) alkyl, aryl gps. L is a mobile ligand or part of a mobile ligand and X is a non complexing anion. (I) is used as catalyst for the oligomerisation or polymerisation of alkenes or 1,n-dienes, pref. under inert atmos. and at 20- 80 deg.C amt. of (I) being 0.2-0.02 mole %. Compared to prior art, use of (I) allows trimerisation, tetramerisation and oligomerisation reactions to be effected in one reactor; synthesis is made easier since no Lewis acid is required; reactions can be effected at around 40 deg.C, thus reducing energy requirements and, finally oligomerisation can be effected in situ so that fuels can be produced in situ from excess propylene or ethylene. The polymers and oligomers may be used as elastomers (e.g. cis- 1,4-polybutadiene), lubricants (e.g. dodecene trimers) and fuel additives (e.g. hydrogenated dimers and trimers).

Title: Vertical deflection circuit for TV receiver - uses switching power supply circuit to provide current for deflection coil
Inventor: POTIN MICHEL
IPC: H03K4/62
Filed: 1980-11-07
Abstract: A generator (9) produces a sawtooth waveform at the field frequency and is applied through an amplifier (14) to an input (12) of a comparator (13). The other input (15) is obtained from a capacitor (16) charged from a constant current source (17). The capacitor is discharged by an electronic switch (18) during the line flyback period. The comparator output is applied to an amplifier (20) to trigger a thyristor (10) to switch the secondary (2) of a line transformer (1). The conduction time for the thyristor is a function of the sawtooth generator signal level and thus the line number. The secondary winding provides pulses during the line flyback period which are filtered by an inductor (5) and a capacitor (4) whose charge drives the vertical deflection coil (5). A series capacitor (6) maintains a constant sign of the voltage across the coil.

Title: Continuous churning of cream for mfr. of butter - includes emulsifying by injection of compressed air and mechanical agitation for phase inversion
IPC: A01J15/14
Filed: 1980-11-26
Abstract: In a first stage, cream is pumped continuously through an emulsifier in which compressed air is injected to emulsify the cream into a paste-like consistency. In a second stage, the emulsion is subjected to a mechanical agitation which results in phase inversion into butter. The compressed air is pref. injected at a pressure of 8 to 10 bars and its temp. is controlled in order to cool the cream and facilitate the formation of an emulsion. Mechanical agitation of the emulsion pref. takes place in the churning cylinder of a continuous butter-making machine. Downstream of compressed air injection, the interior of the emulsifier and/or passages leading to the agitator are provided with static mixing blades. After injection of compressed air, mechanical agitation can be carried out at less than 50% of the speed of conventional churning. Energy is saved and machine wear reduced. Reduced mechanical agitation reduces the loss of fat in the buttermilk. The prod. is delivered cool and firm.

Title: Intended turn indicator circuit for moped or scooter - is powered from alternator with electronic control of blink rate and applied voltage
IPC: B60Q1/38
Filed: 1981-02-25
Abstract: The circuit reduces the amount of vehicle wiring necessary. Both alternator and turn direction indicator lamps are earthed.

Title: Electromechanical control device for cam operated interrupter switches - has two kinematically connected cam blocks and rotation-axial motion converter
Inventor: PASQUIER PATRICK
IPC: H01H43/10
Filed: 1982-03-02
Abstract: The electromechanical control device has cams, which operate control switches, driven in constant rotation by an electric motor by speed reduction appts.. The cams consist of two cam blocks disposed coaxially one to the other. The first cam block is joined angularly to a shaft which is kinematically joined to the output of a first speed reducer, although able to slide axially on the shaft to occupy one of at least two axial positions. In the first position the block is at rest, in which it is not placed opposite the switches which are to be operated, and in the second active position it is placed opposite the switches. The first cam block is kinematically connected via a second speed reducer to the second cam block. A control mechanism placed frontally between the two cam blocks, transforms the rotational motion of the second cam block into an axial movement of the first cam block in order to bring it into the second axial position against the action of a spring.
