Title: Light thermoplastics moulded wheel - has two cheeks joined to central hub forming non-inflatable air chamber
Inventor: MOUNIER JEAN-YVES
IPC: B60B5/02
Filed: 1980-06-25
Abstract: The light wheel is made of plastics material and is for use in light vehicles such as handling trollies. The wheel centre section has two identical cheeks (1). The shape of these gives, peripherally, an air reservoir forming a non inflatable air chamber (1c). This chamber can eventually be made airtight during moulding of the wheel rolling track (2). Each cheek has a central web, and the inner face can have radial ribs joined to the centre hub forming half of the air reservoir. Various cheek alternatives can also be used.

Title: Machine for spreading sauce etc. on top of food prods. esp. pizzas - is readily adjustable for prod. size and sauce viscosity
IPC: A21B3/16
Filed: 1980-06-26
Abstract: A machine for spreading a sauce, paste etc. as a topping on a flat surface, partic. the top of a food prod. such as a pizza or tart. The spreading is done by a palette knife type of scraping blade. The blade is fixed to a rotatable support which turns about an axis vertical to the flat surface. The method of mounting the blade on its support allows the angle of the spreading edge to the flat surface to be adjusted. Pref. the blade support can be displaced, e.g. by fluid power cylinder, along its axis of rotation to move the blade to and fro w.r.t. the surface on which sauce etc. is to be spread. Pref. the spreading area of the blade is connected to the blade support by a resiliently deformable arm. The machine can be installed in a high speed prodn. line for pizzas etc. The blade is easily adjusted for different sizes and thicknesses of prod. Spreading pressure can be automatically adjusted for various viscosities of sauce, etc. Spreading pressure is self-relieving to avoid damage to the top of the food prod.

Patent FR-2473585-A1 (FR)
Inventor: WILDFANG DIETER
IPC: E03C1/084
Filed: 1980-08-29
Abstract: The jet-dividing device (6) has a perforated plate (7) with a number of dividing holes (8) passing through it. One portion of the dividing holes (8) is designed as a polygonal hole (9), the axial length of which is from 0.2 to 0.5 mm. The other portion (11) of the dividing holes (8) has a round cross-section, the surface area of which is larger than that of the polygonal hole (9). This results in good jet division; two or three downstream jet-regulating screens (16) are sufficient. The jet regulator is quiet and of simple construction.

Title: Regeneration of zeolite-noble metal hydrocracking catalyst - including water-vapour treatment between coke oxidn. and redn.
Inventor: MARCILLY CHRISTIAN
IPC: B01J29/90
Filed: 1981-01-26
Abstract: Zeolitic catalysts contg. a hydrogenating metal are regenerated as follows: after use in hydrocarbon conversions, esp. hydrocracking. (i) the coke is burnt off at a temp. of 300-600 deg.C in an inert gas with an increasing proportion of O2; (ii) after cooling to a temp. of 0-250 deg.C, the catalyst is hydrated by treating with water vapour; (iii) after purging, the catalyst is treated with H2 at increasing temps. in the range 150-600 deg.C. In a heavily deactivated catalyst, (i) and (ii) may be sepd. by (ia) treatment with NH3 vapour to dissolve and disperse the metal. The zeolite is pref. a zeolite Y or mordenite (both with replacement of most of the alkali ions with H(+), alkaline earth or rare earth), erionite, offretite, ZSM 5 or ZSM 11. It pref. contains a Gp. Ib, IIb or VIII metal, esp. Ni, Pd and Pt. Inclusion of (ii) gives a catalyst of improved performance, and esp. stability.

Title: Tool guide, esp. welding torch guide - has low power auxiliary plasma or TIG arcs to control welding path
IPC: B23Q35/129
Filed: 1981-02-06
Abstract: A device is moved through the gap between two metal edges so that its general direction of movement is parallel to the edges, while allowing weaving of the device w.r.t. the edges, by using one or more plasma or TIG arc. as guides. Pref. one or two low power auxiliary plasma or TIG arcs are used. When two auxiliary arcs are used, one is used to detect a left edge and the other is used to detect a right edge. The method is useful for guiding a welding torch along a weld groove. The arc does not displace the edges, is not sensitive to welding heat and gives accurate guiding irrespective of any non-metallic impurities on the metal edges.

Title: Automatic document cutting and sorting machine - includes cutting wheel and inclined guides stacking cut documents together
Inventor: MOREAUX MICHEL
IPC: B65H35/02
Filed: 1981-02-18
Abstract: The appts. includes two parallel shafts (1A) extending across a frame (1). The shafts include wheels (4A-7A) in pairs which are rotated so as to draw a document through between them. One central wheel includes a cutting disc arranged to cut the document along a line (XX) perpendicular to the shaft axis but parallel to the direction of the advancement of the paper. Once the paper has been cut into two pieces, the advancing sheets encounter two inclined guides (10(1),10(2)). These are arranged to make the two sheets overlap progressively until they are eventually stacked on top of each other. After cutting, one sheet is lifted higher than the other to ensure they they do in fact overlap as the inclined guides move them together.

Title: Resistance strain gauge sensor - is formed of parallelepipedal block of alloy with central aperture and symmetrical strain gauges
Inventor: DAN FELICE DAL
IPC: G01G3/14
Filed: 1981-07-08
Abstract: The sensor is constituted by a parallelepipedal block (1) machined or pressure-moulded with a pref. asymmetric central hole (2), trapezoidal in shape with corners rounded into semi-cylindrical grooves (3). The thickness (E) of material between the grooves (3), or between them and the edges (4,5) of the block, may be variable or may differ between the top and base.

Title: Static solar collector using photovoltaic cells for pump - uses fixed linear reflector and bank of collector tubes which carry more fluid heated
IPC: F24S20/20
Filed: 1981-11-23
Abstract: The collector tubes are co-planar and parallel to each other and run along the focal zone of the reflector, spanning the area on which solar energy is concentrated as the angle of the sun increases and decreases. The tubes are connected in parallel, and each has a smaller dia. tube running coaxially along its length. As the fluid is heated its viscosity decreases, allowing a greater flow rate. In this way the fluid flows more strongly in the hotter tubes, thus increasing the energy conversion of the device. The fluid circulation pump is energised by photovoltaic cells, thus providing autonomous operation. The housing is moulded from a single section. The reflectors are supported on ribbed sections which also act to support the absorber.
