Patent FR-2310808-A1 (FR)
Title: Flat cheese painting equipment - has inclined conveyor belt and return chute for coating both sides
IPC: B05B13/02
Filed: 1975-05-14
Abstract: The flat items painting equipment paints the first face of the items and then dries them. After drying, they are returned automatically to the starting point, where the second face is painted and then dried, being finally returned to the starting point again. The items can be supported on an endless belt during the first operation, this then transporting them through a drying tunnel. At the end of the latter they fall off the belt into a return passage curved upwards at the end so as to leave a space between it and the belt less than the item diameter. The items or thus turned the other way up as they fall into the passage.

Title: Clothing article printing process - stretches and holds over supporting roller
Inventor: KATO HARUO
IPC: B41F17/38
Filed: 1976-04-21
Abstract: The process uses a supporting roller, over which the article is stretched and held during the operation. The roller can be rotated as the article is in contact with the printing die etc. The circumference of the roller can be greater than that of the article stretched over it, and there can be recesses or holes in it. A recess can be used to accommodate the heel of a sock, and a vacuum can be applied to the holes to secure the article in place during the operation. Where the article has straps, these can be accommodated in grooves provided in the roller. Printing can be effected by applying printing paper under pressure and heating the part to be printed.

Title: Analogue computer for three-dimensional objects perspective display - calculates two horizontal and vertical components of chosen perspective and displays them
Inventor: MALAVARD LUCIEN
IPC: G06G7/34
Filed: 1976-06-11
Abstract: The perspective computer treats the three dimensional coordinates of points to be put into perspective. It produces at its output two dimensional coordinates of points of the required perspective. It carries out four successive variable changes; a translation related to the centre of the three dimensional object, two rotations which permit a choice of the azimuth and the height from which the observer will see the object, and lastly the change of perspective variable which is dependent upon the distances of the observer from the viewing screen on the one hand and to the centre of the object on the other hand. The preferred method of taking the three dimensional coordinate points of the object is by means of a coordinate plotting table.

Title: Adjustable telescopic pole - having a steel, PVC-sheathed internal tube and two PVC external tubes
IPC: E04B2/74
Filed: 1976-06-11
Abstract: The adjustable telescopic pole which is intended to be used as a support between two parallel partitions, such as a ceiling and floor. The pole consists of two exterior tubes made from PVC, which fit over an interior tube made from steel sheathed in PVC. The bottom of the interior tube is fitted to a bolt head and between the belt and the nut is a supple ring and a washer. The bottom exterior tube is provided with exterior ribs which engage in grooves in the nut, allowing longitudinal movement, but rotation of the exterior tube squashes the ring, ultimately locking the tubes together. The top exterior tube is connected by a cylindrical spring to the interior tube and both exterior tubes are provided with support plates.

Title: Stone-removing (N)-acyl-(2)-pyridyl-thiazolidine-(4)-carboxylic acids - prepd. by (N)-acylating the (N)-unsubstd. cpds.
IPC: C07D417/04
Filed: 1976-07-01
Abstract: New thiazolidine carboxylic acid derivs. are of formula (I) (where R1 is 2-17C alkanoyl; and R2 is carboxy or one of its functional derivs. i.e. an ester or amide gp. or an inorganic (esp. alkali(ne earth)) or organic (esp. amine) salt of the carboxy gp). (I), their optical isomers and acceptable acid addn. salts are useful for treating kidney, liver and gallstones, in that they are capable of bringing about dissolution of oxalate, phosphate, uric acid, cystine, etc. accretions. In addn., they are also useful for treating metabolic disorders; this is because they introduce biological sulphur into the organism, where it has a plastic, energetic and protective effect. (I) can also be used in veterinary medicine, e.g. to increase the wt. of piglets, foals, etc. and to reduce their mortality during the first 56 days of life.

Title: Overhead conveyor with endless carrier chain - has deflector plates to transfer goods from one side of wall to opposite side
IPC: B65G43/00
Filed: 1976-10-15
Abstract: The overhead conveyor includes a conveyor chain which is located by two drive sprocket wheels. The sprocket wheels are on top of two pillars which stand in line and form part of a wall. Guide panels with integral support tracks for the conveyor chain are attached to vertical rails on the pillars. Equally spaced attachments on the conveyor chain are used to transfer articles from one side of the wall to the other. Fixed sensor arams are located where the conveyor loads move through a hole in the wall. Thus a misplaced load hits the sensor arm which then will operate a switch that stops the conveyor drive.

Title: Image intensifier tube power supply - has light level compensation governed by overall tube power level
Inventor: HOOVER ALAN WILSON
IPC: H02M3/338
Filed: 1977-01-06
Abstract: The power supply circuit for image analyser or image intensifier tubes uses microchannel techniques. The design is intended to reduce the cost and complexity of circuits providing compensation for variation in image light level and includes protection against intense light levels using the microchannel inherent resistance as part of the protection circuit. Variations of light level are accommodated by basing the supply level control on detection of the overall tube power rather than detection at the tube screen. This variation in overall current is fed to the LT circuit where a pair of transistors provide a feedback signal controlling the output of the supply circuit oscillator.

Title: Thin sheet roof gutter angle piece - is monolithic deep drawn unit with curved walling at angled convergence
IPC: E04D13/064
Filed: 1977-06-27
Abstract: The roof gutter angle piece is made of metal or non-metallic sheeting, less than 1 mm thick, with angle shanks arched downward in a trough shape. Zinc or copper, 0.5-0.8 mm thick, are suitable materials. It is produced from one piece, by deep drawing, and has a walling section, facing the roof edge or facing away from it, curved in an arc shape where the sections converge at an angle. The walling section (7) with the curve (4) may be rolled over into a seam (8) on the side facing away from the roof; or the angled walling piece facing away from the roof edge may be rolled over in this way. This improves connection and reduces likelihood of deformation, while rainwater does not have to pass over a sharp corner, leading to dirt collection.
