Title: Apparatus for grinding and mixing a pasty, semi-solid food material
IPC: B02C18/06
Filed: 1981-12-31
Abstract: A grinder/mixer which provides some of these advantages. A grinder/mixer described comprises a pressure vessel which has a paste inlet for receiving a supply of semi- solid paste formed by the injection pressure, means for grinding the semi-solid supply (food, feed), and means for mixing the ground supply with solvent added to the pressure vessel via a solvent-inlet port. In the preferred embodiment, the mixing means comprise two helixes mounted for rotation in the vessel. The grinding means comprise a plurality of grinding blades fixed to the outer radial ends of the helixes, in an arrangement such that the grinders shear the supply when the latter enters the vessel. In one aspect of the invention, the grinding blades have a sharp front edge which is caused to rotate so that it shears the flow of semi-solid supply perpendicularly. In another aspect of the present invention, there are a plurality of deflection members inside the pressure vessel for assisting in directing the recirculation of the mixture of paste/solvent through the area for mixing and grinding. In yet a further aspect of the invention, an annular member is fixed to the tips of the blades of the helix, on each helix, and the grinding blades are fixed to the annular members.

Title: Formation of print surfaces.
IPC: G03F1/00
Filed: 1982-02-05
Abstract: A print surface is formed by photoexposure of a photocurable resin layer through a photomask comprising an image-wise distribution of opaque material on its image surface, and sticking of the image surface to the resin layer during photoexposure is prevented by providing over the image surface a clear thin film of a natural gum or other material that is impermeable to softeners such as alcohols that are liberated from the resin layer. A coated photomask may be made by image-wise laser scanning of a transparent sheet to which opaque material such as graphite is bonded by a binder such as an alkyl cellulose, followed by application of the film over the resultant image-wise distribution of opaque material.

(2/5) DEAB- DE3231405 C The gas gun has a breech block housing, barrel and coaxial bore and mounted guide and piston coaxial to the barrel as well as a head and ring casing radially spaced from the barrel, using piston and guide to form the gas chamber and a channel in the barrel as link between chamber and bore. A hollow piston (46) carried by the guide (42) within the casing (40) is urged by spring (52) axially against the firing direction into a rest position where the piston bears against a flange (50) on the barrel. - From this setting the piston is ejected axially in the firing direction by the chamber gas (34) into a gas emission setting and so links a vent channel (58) in the guide to atmosphere. The guide is a ring shaped sleeve fixed ahead of the casing to the barrel and with several angularly spaced fingers (44) reaching into the casing so as to carry this and the piston to enable them to adjust axially relative to the barrel.

Title: Process and apparatus for the preparation of a chocolate paste.
IPC: A23G1/04
Filed: 1984-08-24
Abstract: The ingredients of the chocolate i.e. cocoa, sugar, etc. are treated conventionally by milling, dispersing in cocoa butter and refining to a fluid paste. The paste is degassed and cleansed of undesirable volatile substances by a treatment which includes passage through a conveying chamber via at least two parallel conveying screws. The chamber is equipped with a ttem temp. control system. - When the paste is transferred from the refiner to the conveying chamber, it is there first subjected to a dry conching stage. The dry-conched paste is then liquefied by incorporation of additives. The dry-conching stage involves two successive steps. The first step comprises simple mixing with temp. rise. The second step comprises mixing, plus high shear with lamination of the prod.. The shear and lamination effect is progressively increased. The temp. control system endures that the temp. is maintained at the temp. suited to optimum conching with conservation of desired grain size within the paste. The dry-conching stage, each stage if more than one, is followed by degassing.
Patent ES-8601727-A1 (ES)
Title: Method of and plant for grinding pulverulent or granular materials.
IPC: B02C15/04
Filed: 1984-12-27
Abstract: The grinding method for pulverent/granular material involves feeding the material onto a rotating grinding table (1) for grinding by using rollers (3). Material which is fully ground is separated from insufficiently ground material in a first separator (6) and discharged. - In the method, part of the combined completely- insufficiently ground material is removed before it is fed to the first separator and is fed instead to a second separator (13). Here the combined material is separated from conveying gas and is introduced into a feed (9) of fresh unground material being supplied to the grinding table. (1/1) USAB- US4582260 A The method for grinding pulverised granular material utilises a vertical roller mill with a grinding table (1), rollers (3) and a separator (6) for separating ground material. - The material is conveyed to the separator in an air stream supplied through an inlet (7). - It is separated into a fine fraction, which passes out through an outlet (8) and a coarse fraction which is returned for further grinding through an outlet (10). - A part of the ground material is conveyed through an outlet (11) to a second separator (13), where it is separated from the air. - Then it is returned for further grinding via an outlet (14) and an inlet (9) for fresh material to the mill. - This provides a flatter grain size distribution curve in the finish ground material.

Patent ES-8605627-A1 (ES)
Title: Adjusting device with overload slip system
IPC: G01D5/165
Filed: 1985-04-11
Abstract: The motor (4) for altering the position of a linear setting device (10) drives through  a planet gear (7). One of the elements of the gear is a stationary ring (16) with internal teeth. The ring is held, relative to the motor housing (1), by friction pads (17). If the linear element (10) comes to the limit of travel the excess motor torque causes the fixed gear ring (16) to slip relative to output shaft (8) and housing (1). - A potentiometric position sensor (24) has a plate (25) attached to the fixed housing (2) of the linear drive (10). The moving contact part (28) is attached to the ring (21) driving the output shaft (8). Thus any slip of the planet ring (16) does not affect the output of the position sensor.

Title: Coating for prosthetic devices.
IPC: A61L27/50
Filed: 1986-06-05
Abstract: A novel implantable prosthesis for implantation in human patients is disclosed which comprises a synthetic substrate and a Type IV/V collagen surface layer seeded with a confluent monolayer of autologous endothelial cells. In the preferred embodiment, a base layer of interstitial collagen is adhered to the substrate. The Type IV/V collagen surface layer is provided in a laminate comprising an intermediate layer of interstitial collagen which is covalently bound to the aforementioned base layer. A cross linking agent, such as glutaraldehyde, is utilized to covalently bind the interstitial collagen base layer to the substrate, and the collagen intermediate layer to the base layer. The cross linking agent is subsequently deactivated with a soluble peptide, such as lysine. Autologous endothelial cells, such as microvascular endothelial cells derived from adipose tissue, are then seeded at high densities on the pretreated graft material. Those cells adhere in suitable precentages within times compatible with most vascular surgical procedures, and, even more importantly, flatten on that surface to assume the appearance of a natural, cobblestone morphology. The subject surface is resistant to shear stress, and yields good results when tested as a vena cava implant in dog.
