Title: Method of pre-concentrating heterogeneous mineral mixtures
IPC: B03B5/48
Filed: 1976-05-14
Abstract: A method for dividing a heterogeneous collection of ore particles prior to concentration thereof into groups differing in size and density of the particles by passing the particles in dispersion in a liquid through a space having obstacles therein which are arranged such that the sizes of the openings between the obstacles are always larger in size than the major number of particles arriving at the openings while simultaneously agitating the medium. This results in a variation of the path of the particles depending on their size and density and allows only the smaller and/or heavier particles to be brought to the concentration.
Patent ES-448042-A1 (ES)
Title: Printing system having a hot roll fuser with a scraping blade cleaner
IPC: G03G15/20
Filed: 1976-05-18
Abstract: In a xerographic printing system the toned copy paper is fused by the pressure nip formed by a hot roll and a backup roll. A scraping blade engages the destructible surface of the backup roll at a critical angle which is selected as a function of the coefficients of friction of the backup roll's surface and the toner/debris contamination that may be collected on the backup roll's surface. As a result, the blade slides freely on the roll's surface, but does not slide on the surface of the toner/debris contamination film. This film forms a locking angle with the blade, placing the blade in stress, and developing a film removing chisel-like action therewith.

Patent ES-469363-A1 (ES)
Title: Ring clamp and method of making same
IPC: F16B7/08
Filed: 1978-05-02
Abstract: A ring clamp has a pair of flexible sheet-metal strips formed into a ring with one end of each strip juxtaposed with the one end of the other strip, and the other end of each strip lying intermediate the ends of the other strips. The buckles are each formed of a pair of sheet-metal parts one of which has ends bent over and formed with channels into which fit similar channels of another latch part whose ends are in turn bent over the first part for locking-together of the entire buckle into a rigid unit without the use of welding or rivets. Furthermore each buckle has inwardly directed teeth that can bite into the object being clamped. When the ends of the clamp are drawn together to tighten it around an object the two buckles are tightly pressed against the object and prevent sliding of the two strips relative to each other.
Patent ES-476511-A1 (ES)
Title: Dispensing apparatus for machines for packeting cigarettes into hinged-lid rigid type cigarette packets
IPC: B65B19/30
Filed: 1978-12-29
Abstract: A dispensing apparatus for machines for packeting cigarettes into hinged-lid rigid type cigarette packets is of the type comprising an intermittently rotating wheel having radially disposed compartments for housing individual cigarette packets. A dispensing channel is associated with the wheel and upper and lower heated plates cooperating with the compartments. A pushing member is provided at the end of the dispensing channel to push, during the normal operation of the apparatus, the individual packets into a first track coplanar to the dispensing channel. A control mechanism, should the wheel accidentally stop, acts on a pair of mechanical systems which cause the spacing apart of the plates from the compartments and further starts a timer. Should the stoppage of the wheel last longer than a preselected time, the timer actuates locking means which lock the pushing member to discard, along a second track disposed in line with the dispensing channel at the restoration of the normal operation of the apparatus, a number of packets corresponding to the total number of packets contained in the apparatus.

Patent ES-8102998-A1 (ES)
Title: Method of treating calcined gypsum and manufacture of gypsum board therefrom.
IPC: C04B11/00
Filed: 1980-04-17
Abstract: Calcined gypsum (stucco) is treated by blending therewith small portions of water (about 1-10% by eight of the stucco), allowing it to heal, and grinding the healed stucco to increase its surface area. This results in a reduction in water demand with good retention of set strength. If the treated calcined gypsum is not used shortly after the healing procedure, it should be dried before grinding to provide storage stability. The reduced water demand is particularly useful in gypsum board manufacture.

Patent ES-8103590-A1 (ES)
Title: Drive cam and follower for a liquid fuel injection pumping apparatus
IPC: F02M59/26
Filed: 1980-07-14
Abstract: A liquid fuel injection pumping apparatus comprises a reciprocable pump plunger operable by a tappet assembly and a rotary cam. The tappet assembly includes a cylindrical body slidable within a bore, the body carrying a cross pin which supports a roller engageable with the cam. The cross pin has reclined ends so that if it moves axially while exposed beyond the end of the bore it will engage the bore and move axially to its correct position. With cams designed to give maximum plunger movement the pin is exposed for an appreciable time and heavy wear of the pin and bore can occur. The cam is therefore designed to allow outward movement of the plunger but then to hold the plunger until just before inward movement of the plunger is required to take place. Whilst the plunger is held the filling port of the pump is at least partly uncovered. The cam has a trailing flank which comprises a first part during which the plunger can move outwardly, a second part during which the plunger is held against outward movement and a third part which allows the full outward movement.
