Title: T.V. receiver mains voltage compensation - relays operated by reference voltage circuits to select autotransformer tappings
IPC: G05F1/20
Filed: 1974-06-04
Abstract: The mains supply to a colour television receiver is adjusted by relays which select a tapping on an autotransformer when the input varies by a predetermined voltage. A relay operated by load current ensures connection of the circuit. This system overcomes problems of damage to stabiliser circuits when large input variations occur. A mains supply is connected to an autotransformer with part connected to a bridge rectifier providing a voltage for reference voltage control circuits. The reference levels are provided by zener diodes and adjusted by potentiometers for application to transistor base circuits driving second transistors with relays in their collector circuits. Relay contacts select tappings on the autotransformer to compensate for supply variations. A third relay operated when load current is present connects the circuit into operation.
Patent FR-2275239-A1 (FR)
Title: Rotary drum filter sepg. solids from suspensions - with periodic scraper movement into precoat giving longer precoat life
Inventor: POLLOZEC FRANCOIS
IPC: B01D33/00
Filed: 1974-06-21
Abstract: A method of sepg. particles of solids from a suspension by filtering on a rotary drum filter on which is deposited a pre-coat, incorporates imparting to the scraper an alternating motion at regular intervals. During this alternating motion, the scraper is advanced so that it penetrates deeply into the pre-coat, at a rate such that the drum is not stopped, held in this position for one revolution and then withdrawn to its original position, at a rate greater than that of the reforming of the pre-coat, so that the scraper does not compress the pre-coat, fed as a pulp in a predetermined proportion. The method eliminates very largely the effect of clogging in depth of the pre-coat. It allows the reconstitution of a new more permeable pre-coat and avoids the need to stop the filtration.

Title: Lithographic plate with improved hydrophilic non printing zones - by treating with silica, esp. hydrolysed tetra-ethyl-orthosilicate, soln.
IPC: B41N3/08
Filed: 1974-10-03
Abstract: The non-printing zones of a lithographic plate are made hydrophilic applying to the plate, after exposure of the photosensitive layer and removal of the unhardened parts, a hydrophilic and lipophobic compsn. comprising silica followed by removing that compsn. in the printing zones. The hydrophilic properties of the plate are kept intact since the hydrophilic compsn. is applied upon the photosensitive layer after exposure and removal of unhardened zones. Fog formation or smearing during printing is therefore avoided. The process also makes it possible to use an Ag film as offset plate. Sharp line patterns can be obtd. with good contrast between printed and non printed zones.

Title: Rubber shock absorbing bearing - has split cylindrical metal shells transferring axial compression to tubular rubber core
IPC: F16C11/04
Filed: 1975-05-30
Abstract: The rubber cushioned shaft bearing is cheap to produce, simple to assemble and uses low tolerance parts, and is also re-usable and highly reliable. It is constructed by vulcanising cylindrical thin metal rings (4, 5, 6, 7) to the inner and outer surfaces at both ends of a tubular rubber body (1). When assembled on a shaft (9), these rings are compressed axially and held by shoulders (13, 14) at one end and by circlips (10) lodged in the housing (8) a tthe other. The rings are slotted lengthways and covered by a rubber film and vulcanised over their free surfaces. The rings extend at least as far in as the point where the axial frictional force due to compression of the rubber is equal to the shear force between the body (1) and housing (8) or shaft (9), due to distortion of the rubber. Spherical and ogival forms of the bearing are also possible.
