Patent FR-2349084-A1 (FR)
Title: Diaphragm actuated flow control valve - has plate spring to give accurate control at low flows
IPC: G05D7/01
Filed: 1976-04-22
Abstract: The control flow valve has a valve seat (18) closed by a ball (17) due to the force exerted by a conical spring (19). A diaphragm (1) which is loaded by a plate spring (5) opposes the force of the conical spring (19) and pushes the ball off the seat. The orifice plate (10) creates a pressure difference proportional to the flow and the downstream pressure is transmitted to the upper surface of the diaphragm (5) through the holes (11, 12, 13). The plate spring (5) is made from a sheet of beryllum copper by electro-chemical machining. This type of spring gives very accurate control of low rates of flow at low pressures.
Patent FR-2353330-A1 (FR)
Title: Mixing and kneading appts. - used e.g. for kneading of initially solid products into a dough
IPC: B01F7/24
Filed: 1976-04-22
Abstract: The appts. comprises a vessel in the shape of a truncated cone in which is placed a vertical screw surrounded by a sleeve. The vessel is covered at the top by a hood. The screw rotates, thus transferring material from the bottom to the top. On reaching the top it falls back into the mass of material within the vessel which is itself being mixed by a mixer having two arms on a base, following basically the contours of the inside of the vessel. The dimensional ratio between the mixing device and the vessel satisfy very efficient mixing criteria. The permanent scraping of the interior surfaces of the vessel and the provision of a scraper for the outside of the sleeve around the screw prevent the build-up of a layer of the product on those surfaces which would impede the efficient working of the appts. the simplicity of the apparatus allows easy dismantling for any work which may become necessary.
Patent FR-2356049-A1 (FR)
Title: Automobile differential gear - has threaded sleeve to adjust end play of bearings and is locked by cover screws
IPC: F16H48/08
Filed: 1976-06-25
Abstract: The differential assembly of an automobile is supported on tapered roller bearings (11, 12). The outer race (42) of the bearing (12) abuts against the end face of the sleeve (45) which is screwed into the bore of the housing (1). The sleeve has a number of equally spaced holes around its periphery. The housing has a hole (S) to provide access to the holes in the sleeve so that by means of a suitable tool, the sleeve can be rotated and thus enabling the end play of the bearings to be adjusted. The sleeve is then locked in position by the screw (49) which also serves to retain the cover (50).
Patent FR-2359241-A1 (FR)
IPC: D06P1/52
Filed: 1976-07-20
Abstract: Use is made of pigment dyes and, as binding agent, latexes heat-sensitised by the addition of an alkyleneurethane copolymer of formula I, the symbols in which are defined in the claim. The dyed or printed material is subjected before drying to the action of a heat-radiating source in order to coagulate the latex. Pigment migration on drying is thus avoided.
Patent FR-2359799-A1 (FR)
Title: Cement calcining plant - using gravity to feed cement from preheating cyclones through a precalcining chamber
IPC: C04B7/43
Filed: 1976-07-28
Abstract: Preheater is described for a cement calcining plant, consisting of four sets of cyclone separators, where part of the raw material leaving the second set of cyclones flows via gravity into a precalcining chamber. After leaving the chamber, the material flows, also via gravity, into the gas duct leading to the last set of preheating cyclones. In a conventional plant, a rotary drum furnace is followed by a cooler in which air is used to cool the clinker. The hot air thus obtd. is fed through a filter and a blower providing the air pressure necessary to blow the crude cement into the chamber. By using gravity feed, the invention eliminates the need for a filter and blower.

Title: Sliding ladle stopper - with adjustable sealing pressure between refractory slabs by lifting mechanism and springs
IPC: B22D41/40
Filed: 1976-11-19
Abstract: Sliding stopper for the nozzle of tundishes or steel ladles consists of a lower metal frame with a sliding refractory slab which is pressed by a system of springs against an upper stationary refractory slab. The springs rest on a support plate which can be lifted by a hydraulic, pneumatic or screw mechanism to press both slabs together during the pouring operation. A pin can be used to couple arms on the plate to arms on the ladle bottom. This ensures a complete and stable seal between stationary and sliding refractory slabs. Manual operations under high-temp. conditions are saved and wear is automatically compensated.

The dimensions of the sheet (5) are similar to that of the flap (4) except that its length is slightly shorter so that the edge (51) stops before it meets the common axis (2). Thus a sleeve (6) is formed in which is engaged the indicator support (7). The three elements (3, 4 and 5) are connected together by glueing or by high frequency melting if the material is thermoweldable.

Title: Solar energy collector - comprising pigment layer pref. metal oxide fixed to metal layer mechanically or using binder
IPC: F24J2/48
Filed: 1977-08-19
Abstract: A body with a surface having selective spectral properties comprises an external layer of pigment powder mechanically fixed to the low emission surface of a support. The layer itself has a high solar energy absorption capacity and is largely transparent to the thermal radiation emitted by the surface of the support. Alternatively the pigment layer is fixed to the support by means of a binder comprising liquid or solid paraffin and/or polyethylene. Used as a solar energy collector. The process allows the surfaces to be cheaply and reproducibly mfd. The surfaces have the radiation absorption capacity of a normal black surface but have less than one thir dof the emissive capacity of the latter. Use of binder is optional.
