Patent ES-474633-A1 (ES)
Title: Process for the preparation of a vinyl ester copolymer.
IPC: C08F218/04
Filed: 1978-10-27
Abstract: Copolymers of vinyl esters and crotonic acid are commonly prepared by polymerizing the monomers in bulk or in solution by means of a radical-forming initiator in the presence of a regulator. The polymers should be free from residual monomers and impurities as far as possible. This may be realized in that upon completion of the polymerization the unreacted monomers and other volatile impurities are removed from the reaction mixture by distillation. For this purpose, the use of an entrainer is advantageous. The copolymers are suitable as starting materials for adhesives and hair lacquers, hair setting lotions as well as hair sprays.
Patent ES-475404-A1 (ES)
Title: Shaving apparatus
IPC: B02C18/06
Filed: 1978-11-25
Abstract: A shaving apparatus has a circular shear plate provided with hair-entrance apertures and a cutting unit associated with and rotatable relative to the shear plate. The cutting unit comprises a cutting member having a circular central body and a hair-pulling member having a circular central portion. Cutters extend from the central body circumference toward the shear plate, with each cutter having a guide wall. A lead cutter is associated with and movable along the guide wall of each cutter, the lead cutter being connected to the central portion circumference by a V-shaped elastically deformable arm. One link of the connecting arm is secured to the central portion and extends tangentially therefrom and the other limb is connected to the lead cutter. Each connecting arm is elastically deformed so as to urge its lead cutter against the guide wall of the associated cutter.
Patent ES-475651-A1 (ES)
Title: Lead acid storage battery and method of manufacturing same
IPC: H01M10/12
Filed: 1978-12-01
Abstract: Accumulator of the lead acid type which can be activated by addition of electrolyte consists of >=1 assembly of shaped positive and negative plates with insulating separators interposed between adjacent plates. Part of the sulphuric acid used for forming the plates is retained in the accumulator and has a specific gravity of 1.25-1.35g/cc., the amount of acid retained is insufficient to connect the plates during storage. The accumulator includes devices for sealing it against air penetration, but permitting gas produced inside the accumulator to escape. Each positive plate contains >=0.1 cc acid per g. of active material. The strength of the acid retained in the accumulator is high enough to maintain a strongly acid soln. for the plates during storage. Since it is the acid used during formation of the plates, rinsing and drying are avoided. Since the formation of acid has a SG of 1.25-1.35, activation of the battery can be effected with the same strength or weaker acid than that normally used for charging dry accumulators, i.e. 1.26g/cc.

Patent ES-483780-A1 (ES)
Title: Means for driving the back walls of a bucket excavator
IPC: E02F3/24
Filed: 1979-08-31
Abstract: Means for driving the back walls of the buckets of an excavating wheel having a plurality of circumferentially arranged digging buckets. Each digging bucket is provided with a pivotal back wall mounted on the excavating wheel. The excavating wheel is rotatably mounted on a central shaft. A central sprocket is freely rotatably mounted on a bucket wheel hub which is mounted on the central shaft. A mounting bracket is attached directly to the main frame of the vehicle and extends outwardly therefrom. An offset sprocket which is smaller in diameter than the central sprocket is rotatably attached to the opposite end of the bracket. The axes of rotation for the central sprocket and the offset sprocket are parallel. A continuous chain passes around the sprockets with the chain constrained to move in a predetermined path. Push rods are pivotally attached at one end to connecting links of the chain so that the push rods are disposed at equal intervals along the length of the chain. Each push rod is also pivotally attached at its opposite end to one of the pivotal back walls of the digging buckets. Each push rod, as the link to which it is attached passes near and over the offset sprocket, urges its associated back wall to pivot outwardly relative to the central shaft to an extreme outward position which is the material dumping position of the digging bucket. A controlled amount of slack is maintained in the chain so as to impart a whip-like effect to the pivotal connecting links, increasing the velocity of outward wall movement. The push rod also urges its associated back wall to pivot inwardly relative to the central shaft after its associated link has passed over and beyond the offset sprocket to an inner position which is the material receiving position of the digging bucket.

Title: Firearms with rotary magazines.
IPC: F41A9/02
Filed: 1981-07-13
Abstract: A firearm especially for firing large calibre rounds such as rubber bullets and having a rotary magazine (2) which is rechargeable at any stage of depletion. A loading (63) arm serves to guide rounds through an inlet opening in the magazine (2), in such a way that they are received into corresponding locations in a rotating carrier (46, 47), and the carrier rotates forward one position with each additional round. Until the penultimate round, the guide means (63, 64, 65) is locked to the magazine body (40). In this position, it obstructs further movement of the first-inserted round and thus prevents insertion of the final round. Mechanism is described by which, on insertion of the final round the guide means automatically unlocks from the magazine body and locks to the rotating carrier. In this condition it serves to keep the first inserted round locked in the magazine as it completes a full rotation to come opposite the inlet opening once more. Mechanism for firing automatic indexing the carrier, and automatic extraction and election of spent cartridges is described.
