Inventor: SCHIRMANN FRANCIS
IPC: A23L2/38
Filed: 1983-08-04
Abstract: The present invention relates to a process for the obtention of an algae beverage, and an algae beverage thus obtained. The process is characterized in that it consists essentially in cutting and finely chopping a marine algae known as fucus vesiculosus, keeping it in an oven for about 24 hours at a temperature of the order of 120 DEG  C., measuring the degree of humidity upon leaving the oven, and adding alcohol whose alcoholometric degree is comprised between 40% and 65% according to the size of the evaporation loss, at the rate of about 10% by weight of the algae from the oven, then macerating the obtained mixture for about three weeks in a closed receptacle, at ambient temperature, then filtering said mixture and pressing the solids content, thereby to separate all the concentrated liquor, then forming a mixture of the concentrated liquor with a fruit concentrate as well as, if desired, with one or several concentrated essences of fruits, vegetables, or herbs, and with water, and finally, pasteurizing the obtained product at about 85 DEG  C. for about 20 minutes.

Title: Method for preparing portions of compressed powdered coffee [coffee powder] for espresso coffee machine
Inventor: MICHETTI MAURIZIO
IPC: A47J31/30
Filed: 1981-08-27
Abstract: The method envisages preparing portions or tablets (1') of powdered coffee, which have been compressed using a suitable pressure, and wrapping them in a permeable wrapper (3') which preferably consists of a sheet of paper of the type used for portions of various types of tea. The portion or tablet (1') is inserted into the container (2') of an espresso coffee machine for domestic use, of known type or specifically designed for this purpose, reducing the time required to set up the machine and saving a certain amount of powdered coffee since the tablet is compressed to an exactly metered dose. The portion or tablet (1') can be of very elongated shape, reducing the compression of the powder and restricting the amount of coffee used to the bear minimum in view of the fact that the water or steam has further to travel and therefore can get the most out of said powder. <IMAGE>

Title: Method for the hollow drilling of glass panes and hollow drill for carrying out the method
Inventor: MIYANAGA MASAAKI
IPC: B28D1/04
Filed: 1978-06-07
Abstract: With the use of a hollow drill with water-cooled cutting teeth of hard-pressed diamond powder or dust, the glass pane is initially drilled down to a predetermined drilling depth (T1). The drilling depth (T1) is to be 0.5 - 1 mm less than the thickness of the glass pane (23). Then the margin of the glass-pane part lying inside the drilling circle is struck from the pane side which is not machined. The annular glass part no longer machined is thereby pierced so that the drilled-out, disc-shaped core (28) falls out of the glass pane. A stop device (5) adjustable relative to the drilling head (1) butts against the glass pane (23) when the predetermined drilling depth (T1) is reached and prevents further advance of the hollow drill. In this way, glass panes can be drilled simply and reliably without expert ability, in the course of which neat cut edges are obtained. In contrast to known methods, there is virtually no risk here of damaging the glass pane. <IMAGE>

Abstract: 1350332 Forming ultraviolet and blue radiation masks and filters from silver salt images EASTMAN KODAK CO 12 Jan 1972 [15 Jan 1971] 1460/72 Headings G2C and G2J A photographic image that is opaque to ultraviolet and blue radiation and transparent to visible light having a wavelength over 500nm. is formed by reacting an imagewise distribution of a waterinsoluble silver salt with an aqueous solution of a heterocyclammonium salt (i.e., one which forms a complex with a water-insoluble silver salt image which has a density in the ultraviolet and blue regions of the spectrum at least equal to the density of the silver image from which the silver salt image was produced or the density of the silver image which would have been produced if the silver salt image had been developed to a silver image) so as to form an imagewise distribution of the corresponding heterocyclammonium complex of silver. A radiation sensitive silver salt may be exposed, developed and fixed to form a negative silver image which is then oxidised to form the imagewise distribution of a water-insoluble silver salt e.g. using a photographic bleach solution such as a solution containing potassium ferricyanide and KBr. The negative silver image may be oxidized to the water-insoluble silver salt and immediately converted to the heterocyclammonium complex by treatment with a solution containing a heterocyclammonium salt having a nitro substituent and/or a nitrate anion. A radiation sensitive water-insoluble silver salt may be exposed, developed to form a negative silver image and a positive distribution of water-insoluble silver salt, treated with a non-oxidizing heterocyclammonium salt to form a positive distribution of the complex and bleached and then fixed to remove the negative silver image. The heterocyclammonium salt may be N-methylquinolinium iodide, N-(2, 4-dinitrophenyl) pyridinium chloride or 5-nitroquinolinium nitrate. The invention also comprises a photographic mask comprising a transparent support bearing a layer containing a complex of a hetercyclammonium salt as defined above, and silver, the complex being opaque to ultraviolet and blue radiation and transparent to visible light having a wavelength over 500nm. These masks are useful in the photo-fabrication of electrical devices e.g. circuit preparation, and in photo-mechanical reproduction.

Title: Method of fixing of panels at right angles - rubber padded brackets allow deflection under load, for e.g. car roof signs
IPC: F16B5/00
Filed: 1973-04-06
Granted: 1974-10-31
Abstract: The method generally applies to the fixing of two panels roughly at right angles and is suitable for the attachment of sign boards (e.g. Driving School) to the metal roofs of vehicles. The sign board is held by two right angled brackets to a magnetic foot. Between the board and each bracket is an elastic pad to each face of which is bonded a metal plate integral with screws. Nuts complete the assembly. As the vehicle moves forward, air pressure exerts a couple on the board tending to pull the magnetic feet off the roof, but the rubber pads allow the board a considerable degree of tilt eliminating the risk of coming adrift.

Title: Shock absorber for IC engine valve tappet - face plates control oil flow around and through damping piston around tappet
IPC: F01L1/16
Filed: 1973-11-20
Granted: 1975-06-13
Abstract: The lower end of the tapper (4) slides in a bore in the cylinder head (3). The upper part of the tappet (4) is guided by a hole in the cover plate (8). A piston (6) is rigidly attached to the tappet (4) and has a diameter slightly less than the upper part of the bore. The piston (6) is provided with a number of holes covered by thin plates. The lower plate has holes to match the holes in the piston. When the tappet moves downwards, the inertia of the plates uncovers the piston holes allowing a free flow of oil. Downward motion is damped because the oil can flow only through the clearance around the piston.
