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.

Abstract: The invention relates to a lock system for rooms which are to be made exclusively accessible to different uses over different periods of time, for example hotel rooms.      The keys of the system comprise magnetic cards which are provided with magnetically registered data, which for each card includes lock-identification data valid for a given lock or a given group of locks, a validity time expressed in real time and a randomly selected legitimacy code. Each lock includes an electrically actuable lock mechanism (4), a magnetic-card reader (3), a memory (6) for the storage of data, a real-time clock (7), a programming unit (10), a legitimacy comparator (8), and a time comparator (9). The memory (6) has stored therein the lock-identification data valid for the lock. When a magnetic card is introduced for the first time into the card reader (3) of a lock, the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory (6), and the time comparator (9) compares the validity time registered on the card with the real time given by the real-time clock (7). If these comparisons show agreement, the lock opens and the programming unit (10) is instructed to store into the memory the validity time and the legitimacy code registered on the card. When a magnetic card is later introduced to the card reader (3) the time comparator compares the real time given by the real-time clock (7) with the validity time in the card data stored in the memory and the legitimacy comparator (8) compares the data registered on the card with the data stored in the memory (6) of the lock, and the lock is opened when agreement is found between the data compared.      If the comparison made by the time comparator (9) show disagreement, the time comparator compares the validity time registered on the card with the real time given by the real-time clock (7) and the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory and, if these comparisons show agreement, the lock is opened and the programming unit (10) is used to replace the card data already stored in the memory (6) with the data registered on the card.

Abstract: (57) Abstract of the Disclosure A paper material has been invented that contains cellulose substituted by means of N-methylol compounds.  As N-methylol compounds may be used, e.g., reaction products of urea, glyoxal, and formaldehyde, methylolated melamines, and N-methylol-acrylamide copolymers.  The paper is manufactured best by impreg-nating paper with an aqueous solution or dispersion of a N-methylol compound and by drying it at 130 to 200°C in order to produce condensation.  Papers in accordance with the invention have good properties of strength against decomposition and wet strength, which properties can be adjusted readily by varying the degree of substitution or cross-linking of the cellulose.  The papers axe particularly well suitable, e.g., for the manufacture of plant-growing pots and corrugated fibreboard.

Abstract: DRY VISCOUS SPRING STRUT Abstract of the Disclosure A dry viscous spring strut is provided having at least a top outer housing member, a bottom outer housing member, a shear spring elastomerically associating the top outer housing member to the bot-tom outer housing member, a selectively pressurizable gas chamber, a subchamber disposed in association with the gas chamber including a plurality of elastomeric particles, a rigid structural member asso-ciated with the top outer housing member, and a bearing portion associated with the bottom outer housing member to receive the structural member.  The structural member is received in the bearing portion to bear side loading forces to the strut and to limit non-axial deformation of the strut.  Relative movement between the top and the bottom housing members operates to stress the shear spring and the elastomeric particles, vary the pressurization of the gas chamber and subchamber, and vary the positioning of the structural member relative to the bearing portion to absorb shock and dissipate energy imparted to the strut.  At least one of the housing members includes a casing wall contiguous to the shear spring configured in an arcuate bell-like form to accommodate deformation of the shear spring during compression of the strut.

Abstract: Abstract Lamp Socket Assembly For Mounting On Printed Circuit Board A lamp socket assembly for use with a printed circuit, particularly where the mounting aperture in the circuit board is relatively small and the board may be remotely located.  The assembly includes a lamp socket and a separate key member.  The key receives the socket in latched relation therewith, the latching arrangement being such as to afford limited longitudinal displacement of the socket relative to the key.  One or more biasing members, such as cantilevered spring fingers, are formed integrally with the socket, or preferably the key, and act to urge the socket relatively forward from the key.  Electrical leads from the lamp pass over a flange formed at the base of the socket and are urged upwardly with the base into good electrical contact with the printed circuit on the under side of the board. The key member is preferably elongated to afford remote installation of the socket assembly on the printed circuit board.

Abstract: ABSTRACT   The invention relates to a method for recovering the metal values from materials containing at least one of zinc and tin, by smelting the starting materials under oxidizing conditions and reducing the resultant molten bath. The starting mate-rials are first smelted in a furnace while adding flux, to form a slag which is sluggish at selected reduction temperatures and of low lead contents. The reduc-tion process is carried out while charging solid carbonaceous reduction agent and optionally also sulphur- and/or chlorine-donor material to the slag. The reduction agent and optionally supplied donor material is brought into suspension with the slag, and this suspension is sustained at least during the latter phase of the reduction period, at which the lead content of the slag has fallen to beneath about 1-2%, during which phase the reduction of zinc and tin takes place. Zinc is recovered from the furnace in the form of zinc vapour, while tin optionally is removed as volatile tin sulphide, chloride or oxide, and lead and any other metal values present in the starting materials are recovered as a molten lead phase.
