Title: Double yoke universal joint - has four pin central cross with needle bearings lined with elastomeric damping caps
IPC: F16D3/28
Filed: 1976-01-09
Abstract: The universal joint has two yokes, each of which is connected to a central cross provided with four pins perpendicular to each other. The pins are each located in an aperture of a corresponding yoke arm by means of a needle bearing. A housing (32) made of elastomer material is provided between each bearing (26) and each yoke arm of both yokes (10,12). This provides a damping effect, interrupting the transmission of noises and/or vibrations through the joint. The housing (32) is under radial and/or axial pre-tension, and is retained in a cap (34). It (32) can be made of rubber.

Title: Battery charging installation for public transport vehicles - includes charging points at positions along route where vehicle stops long enough to make charging worthwhile
IPC: B60L11/00
Filed: 1976-02-13
Abstract: An installation for operating battery driven vehicles, in particular, those running on fixed routes in built up areas. It consists of a battery charging post used at night and placed in a garage. This can be used whenever the vehicle is available for battery charging.

Title: Control of frequency of isolated network - uses selective application of brake to motor or alternator to absorb power variations
Inventor: MEGNINT LUCIEN
IPC: H02P29/00
Filed: 1976-07-01
Abstract: The process is used for the absorption of the difference between the constant energy produced by the power of a group of electric current generators powering an isolated network, and the variable energy required by the network at each instant. This is in order to maintain the frequency of the network at its nominal value. The energy is dissipated by the application of a brake controlled by a regulator responsive to the frequency of the network. The brake may be fitted directly on to the shaft of the alternator, or may be fitted to an electric motor powered by the network. The brake may be mechanical or hydraulic.

Title: Hexa:methylene-di:amine prepn. from 2-cyano-cyclopentanone - by catalytic reaction with ammonia and hydrogen
IPC: C07C209/48
Filed: 1976-08-02
Abstract: Prepn. of hexamethylenediamine (I) comprises contacting 2-cyanocyclopentanone (II), or adiponitrile contg. 0.05-0.60(pref. 0.10-0.50) wt. % (II), with a mixt. of NH3 and H2 in the presence of an opt. promoted activated Fe oxide catalyst. The reaction is carried out at 100-275 degrees C (pref. 100-200 degrees C) and a pressure of 300-600 kg/cm2. The NH3: (II) molar ratio is >=4:1 (pref. 4-270:1) and the H2 pressure must be sufficient to prevent conversion of the activated catalyst to Fe oxide. (I) is useful as a detergent, emulsifier or polyamide intermediate. Process allows conversion of adiponitrile contaminated with 2-cyano-cyclopentylidenimine (III) into pure (I), since (III) can be converted to (II) by hydrolysis.

Title: Polycarbonates with (meth)acrylic end-gps. - and their conversion to transparent films, esp. as lacquers for paper
Inventor: PASSAGNE CLAUDE
IPC: C08G63/64
Filed: 1976-12-23
Abstract: New (cyclo)aliphatic polycarbonates of mol. wt. =3000 include hydrocarbon radicals of is not 4C and may contain (thio)ether bridges; they also have two (methy)acrylic end-gps. Polycarbonates are susceptible to self-polymerisation on heating or under u.v. radiation to give transparent films with many end-uses, but esp. as lacquers for papers for use as playing cards, wrappers, etc. A hydroxytelechelic aliphatic or cycloaliphatic polycarbonate is a esterified with a slight excess of (meth)acrylic acid in presence of an inert aromatic solvent that forms an azeotrope with water, in presence of a polymerisation inhibitor and an acid catalyst. Reaction takes place under reflux with regular removal of the azeotrope. Polycarbonates easy to apply since many of them are liq. Also they are chemically neutral and therefore can be applied to most natural or synthetic supports.

Title: Telecommunications submarine cable made of aluminium - has co-extruded layers of plastics insulation laid on aluminium conductor
IPC: H01B7/282
Filed: 1977-05-06
Abstract: A submarine cable is intended for use in high density multi-channel telecommunications applications. The cable has constant electrical characteristics and high resistance to cleavage between the various conducting and insulating layers preventing the progress of gasses and moisture along the cable length.
