Title: Suspensions of brittle bodies - prodn which are evenly dispersed in a liquid suspension medium
IPC: A23L27/00
Filed: 1972-06-30
Abstract: A stable suspension of brittle bodies (e.g. capsules having walls of a natural or synthetic polymer or gel) in a liq. suspension medium is prepd. by entraining the brittle bodies in a liq. vehicle so as to give a mixt. which is fed into a receptacle at the same rate together with the suspension medium. Damage to the brittle bodies is avoided, the process being used in prepn. e.g. of detergent compsns., for incorporation of pleasant tasting or attractively coloured ingredients into foodstuffs such as iced drinks, ice-cream, mayonnaise, and also for cosmetic articles mfr. e.g. nail lacquer.
Patent FR-2159487-A1 (FR)
Title: Thin flat glass - by forming sheet on molten bath, and drawing sheet along bath while correlating velocity/width of sheet
IPC: C03B18/06
Filed: 1972-11-10
Abstract: Thin flat glass is produced by forming a sheet of glass on a molten bath, and applying forces on the edges of the sheet at places situated along the sheet to retain the sheet and prevent it from contracting, while drawing the sheet along the bath at a velocity sufficient to ensure the production of glass below the equilibrium thickness at the exit end of the bath. The velocity and the width of the sheet are correlated, at least at the place of the sheet which immediately preceeds the point where thinning out ceases, according to the equation: V=Q (KW3)-1 (where K = h/We; Q is the prodn. volume of the glass in the sheet; V is the velocity of the sheet at this place; W is the width of the sheet at this place; and h is the thickness of the sheet at this place). Method gives high quality glass with a thickness of =2.5 mm or less, a low optical distortion, and a desired width.

Title: House telephone support and switch - magnets interrupt microphone and receiver circuits
IPC: H04M1/02
Filed: 1974-03-28
Abstract: To overcome the switching difficulties of using a support for the handset which also mechanically operates the interrupt switch, this switching action uses magnets. One magnet is situated in the handset and another in the support box, and so arranged that their poles attract each other. Between the handset magnet and the face nearest the support box are located two switches influenced by the magnetic fields. In the rest condition the flux around the switches cancels and the contacts open. When the handset is removed from the support box the single magnet flux causes the contacts to close. These switches are in the microphone and receiver circuits.

Title: Crane load anti-gyratory mechanism - has articulated link between upper frame and lower one engaging with load
IPC: B66C13/08
Filed: 1974-03-29
Abstract: The mechanism prevents swinging and oscillation of the load and keeps it correctly aligned, and comprises an articulated linkage (3, 4) coupling a top part solidly secured to the chassis of the travelling crane crab etc., (1) to a lower frame (7), solidly secured to the equipment engaging the load and thus cancelling out the gyrator torque. As the lower frame is hoisted, it can come to bear against two or four stops (8). These prevent any swinging or oscillation due to inertia on starting or stopping the crab travel motion. The lower frame can be in two parts turning in relation to each other on a vertical axis in line with the crane hook. The parts are locked together by a pin or brake, so that the load can be altered manually.

Title: Printed circuit card varnishing machine - treats cards placed in vat filled with varnish at pre-determined rate
Inventor: LASSEUR JEAN
IPC: H05K3/00
Filed: 1975-06-27
Abstract: The method for varnishing printed circuit cards which have plug in contacts on one side consists of the following operation. The cards are arranged vertically with their contacts on the upper part are introduced into an empty vat. The vat is filled at a pre-established rate up to an upper predetermined level which corresponds to the foot of the contacts. The vat is then emptied to a lower level which is below the lower part of the cards. The cards are then withdrawn from the vat. The pre-established rate of vat filling is chosen to be less than a predetermined step so as to avoid creating bubble formation on the cards at the line of progressive application of the varnish.

Title: Mixing of two liquids using alternate pulses - pulse width modulated constant freq. signal varies mixing ratio for flow chromatography
IPC: G01N30/34
Filed: 1975-07-23
Abstract: The continuous mixing of two liquids in a continuously adjustable ratio is achieved by introducing alternate pulses of each liquid into a common output line. a constant frequency signal with adjustable mark/space ratio provides the necessary control signal, with the mark (on-period) representing one liquid and the space (off-period) the other. The control signal is generated by two bistable elements connected together as a multivibrator with two adjustable R-C feedback loops. The outputs from the bistables are fed to electro-magnetic coils (7, 8) to switch a sliding spool (4) from one end of a chamber (5) to the other (6). The spool either closes off flow from one inlet (1) over a seat (5) or the flow from the other inlet.

Title: (2,2)-Diesterified diholosides prodn. - from cpd. with all other hydroxy gps. silylated, and a fatty acid or its reactive deriv.
Inventor: TOUBIANA RAOUL
IPC: C07H13/06
Filed: 1975-07-29
Abstract: Process for selective esterification of primary OH gps. in dihalosides (I) comprises reacting the acid halide or alkali metal of an opt. substd. fatty acid with (I) in which the 6-sec. OH's are silylated but the 2 primary OH's are free or replaced by a reactive gp. such as halo. The silylated OH's are deprotected after esterification and the product purified e.g. by chromatography.
