Title: Refractory alumina agglomerates for use as catalyst carriers - contg. metal oxide additives for improved heat stability
IPC: B01J37/00
Filed: 1974-01-10
Abstract: Prodn. of refractory alumina agglomerates (esp. for use as catalyst carriers) by partial dehydration of hydra gillite or aluminium oxide hydrate gel in a hot gas stream and subsequent autoclave treatment opt. in presence of an acid is improved by addition of 1-15 wt. % (pref. 2-7 wt.%) of an oxide(s) of La, Nd, Pr and/or Th (w.v.t. the weight of alumina) and firing the product at =1200 degrees C. The addition of the above metal oxide(s) improves the refractioness of alumina agglomerates (up to 1200 degrees C); their specific surface area decreases only slightly at high temps; they have high porosity and, yet, good mechanical strength (products derived from hydrargillite are supenion as far as the strength is concerned, whilst the products obtained from aluminium oxide hydrate gel have higher porosity; both have very high abrasion resistance). Alkali metal oxides are practically eliminated.

Title: Assembling plastic sheet to other sheet - by engaging lug on plastic sheet in hole in other sheet and deforming lug
IPC: B29C65/60
Filed: 1974-01-18
Abstract: A plastic sheet is formed with lugs or studs projecting from one face and these lugs engaged in holes in another sheet of material (e.g. cardboard, wood chip, cellulosic). The lugs are then subjected to vibrations by e.g. a tamper, exerting a low pressure on the lugs, so that they deform to completely fill the hole and the plastic sheet is secured to the other sheet of material. The method is used in mfr. of lined boxes and is quick, simple and cheap.

Title: Pure nickel oxide powder opt. contg. another metal oxide - produced by mixing metal powder with water and oxidising in two stages
IPC: C01G53/04
Filed: 1974-12-17
Abstract: Prodn. of a pure metal oxide powder from a metal powder contg. Ni and opt. Fe and other metals, by oxidising firing is improved by first superficially oxidising the powder by heating at 370-730 degrees C (pref. 425-540 degrees C) in presence of 2-20% (pref. =18%, esp. 2.5-8%) of water, and then o idising firing at 815-1010 degrees C (pref. 870-980 degrees C). High purity nickel oxide (or nickel-iron oxide) produced by this method can be used in mfr. of ferrites. The preliminary surface oxidn. prevents the sintering of the powder during the subsequent oxidising firing, and the grinding of the prod. is facilitated. A mixt. of carb nyl nickel (or carbonyl Ni-Fe) with water has a much lower heaping density than the metal powder alone (1.4-1.5g./cm3 compared with 2.35g./cm2), whereby the access of gases is facilitated and heat evacuation is promoted so that local overheating is eliminated.

Title: Rubbish collector compacting mechanism - has ram operated upper blade compressing material in lower one after loading
IPC: B65F3/20
Filed: 1975-01-21
Abstract: The mechanism compacts rubbish and waste material in collector vehicles etc. It has an upper blade (A) actuated by a hydraulic ram (C) and pivoting in the top part. This works inside a second blade (B), mounted at the bottom, and driven by the upper one via a link (D). After the material is loaded into the lower blade, the upper one shuts it off and then progressively reduces the volume of the loaded material which is then ejected into the body of the vehicle. Compared with existing designs, the system has the advantage of simplicity, compactness, low cost, and the possibility of mounting on a vehicle, vessel etc. of any capacity.

Title: Mfr of cellular material - with binder poured in spaces between contacting spheres supported by plates
IPC: B28B23/00
Filed: 1975-02-12
Abstract: A fluid or pasty binder is poured around a series of spheres in contact with each other, so as to fill the intervening spaces and solidify. The spheres can be hollow or solid, and of a different material to the binder, or of the same material but with a different density. They can be of different colours, while the binder is transparent or translucent, and they can protrude from one surface of the material. They can be accommodated between two plates (5, 7), forming a composite plate whose thickness is a function of the sphere diameter (4), plus the thickness of the individual plates. Both spheres (4) and binder (6) can be flexible, the pressure inside the spheres being variable.

The system is such that when the fluid reaches the upper float, the upper valve closes. The excess fluid supplied is retained in the upper part of the device, and the stop cock from the supply is closed.
Patent FR-2263771-A1 (FR)
IPC: A61K31/415
Filed: 1975-03-11
Abstract: Parasiticides for controlling ectoparasites are described which contain, as active ingredient, a compound of the formula I in which the substituents have the meaning given in Patent Claim 1. These compositions are administered to host animals infested with ectoparasites, for example flying parasites, such as, for example, flies, and crawling ectoparasites, such as, for example, lice and mites. The active ingredient of the compositions according to the invention is insecticidally, acaricidally and nematicidally active and therefore suitable for controlling any development stages of insects and of mites. On the other hand, the active ingredients of the formula I do not engage in the metabolism of the infested host animals and are translocated in an unchanged state to those sites where the parasites live, where they result in the destruction of the parasites in question. Their toxicity to warm-blooded species is so low that the compositions in question are particularly suitable for oral or percutaneous administration.

Title: Hydraulic press for e.g. injection moulding - has two press blocks guided by four rods driven by hydraulic rams
Inventor: MANCEAU MARCEL
IPC: B29C45/67
Filed: 1975-07-23

The diameter of two of the extensions is less than the dia. of the associated guide rod whilst the diameter of the other two extensions is greater than the dia. of the other guide rods. The guide rods pref. connect the corners of the press blocks and the differences in dia. allow the press plates to be sepd. using only two cylinders. The press is compact and cheap to produce.

The initial shape is rolled into an intermediate shape with cylindrical enveloping surface and with square end faces. This intermediate blank shape is subsequently out in the sizing. The blank from the above process is transverse rolled in which the material in the course of axial forming is displaced in the direction of the forming axis and the reduced waste section is separated in the sizing. The material can also be displaced in the radial direction relative to the axis.

Title: Coal gasification and combustion - with preheated primary air for gasifier and preheated secondary air for combustion chamber
IPC: C10J1/207
Filed: 1976-03-01
Abstract: Useful heat is gained by the gasification and combustion of coal in heat-insulated gasification chamber with enough primary air to release all volatile matter but not enough for complete combustion. Both the primary air and the secondary air, used to mix with the volatile matter and to burn in a combustion chamber, are preheated by contact with the gasifier walls. This produces thermal energy with a high efficiency. The percentage of burnt and unburnt matter in the flue gases is a minimum. The air pollution is reduced and the capital costs are lowered.
