Patent ES-451213-A1 (ES)
Title: Digital phase shifter
IPC: H03K5/153
Filed: 1976-09-03
Abstract: In many digital processing systems it is necessary to delay an applied signal by a time interval which is not an integer multiple of the system sampling period. Disclosed herein is a digital phase shifter which utilizes a particular digital filtering scheme for supplying virtually any predetermined delay. Although conceptually related to the digital concepts of phase shift by interpolation and decimation in which the sampling rate is first increased and then restored to the original sampling rate after effecting the desired phase shift, the disclosed phase shifter operates entirely at the system sampling rate. This is accomplished by establishing a specific predetermined subset of digital filter coefficients and combining the coefficients with the input signal samples in a multiplier and accumulator circuit.

Title: Carpet sweeping device
IPC: A47L11/33
Filed: 1976-12-31
Abstract: A cylindrical brush is mounted in a housing of a carpet-sweeping device or the like for rotation about an axis extending transversely of the direction of movement of the device over the surface to be cleaned. Two dirt-collecting receptacles are located respectively at the front region of the housing and at the rear region of the housing as considered in the direction of movement of the receptacle over the surface being swept. The dirt-collecting receptacles are removably mounted on the housing, and arrested in their respective fully inserted positions. The dirt-collecting receptacle can be introduced into the housing from the side through one of the lateral portions, from the front, from the rear, from below or from above, depending on the particular construction of the housing. Various arrangements for arresting the dirt-collecting receptacle in its fully inserted position are disclosed. The dirt-collecting receptacle proper has an inlet opening bounded by the top and bottom walls, as well as the two lateral walls, of the dirt-collecting receptacle. A guide wall may be provided which extends upwardly from the bottom wall at an angle thereto away from the brush, and a closing wall may be hinged to the top wall of the dirt-collecting receptacle and be held in its open position when the dirt-collecting receptacle assumes its fully inserted position, while assuming its closed position during the removal of the dirt-collecting receptacle from the housing.

Title: Slide fastener with separable end members
IPC: A44B19/38
Filed: 1977-04-20
Abstract: A slide fastener with separable end stop members including an insertion member and a reception member each associated with a respective row of coupling elements on a stringer half. The members have complementary offset steps orthogonal to the slide fastener plane to prevent relative displacement of these members when they are interfitted in a direction perpendicular to the slide fastener plane and are mutually engageable. A slider of generally Y-shaped channel configuration can be displaced upon the rows of coupling elements to interconnect and disconnect them. The slider has arcuate slider flanks receiving the insertion and reception members between them and these members have arcuate surfaces corresponding to the curvature of these flanks and engageable therewith. An abutment is provided to enable the coupling element to be drawn over one of these members, namely, the reception member, in a unidirectional manner and preventing withdrawal of the slider in the opposite direction. The insertion member is shaped so that it can be fitted into the reception member when the slider is disposed over the latter.

Title: Fusion contact adhesives
IPC: C09J7/02
Filed: 1977-10-21
Abstract: Melt adhesive consists of a copolymer of (a) 6 (0.01-3) wt. % phenol and/or terphenol with (b) >=1 polymer such as a butadiene-styrene copolymer, isoprene polymer, natural rubber, chlorobutyl rubber and/or C2H4-C3H6 copolymer. Polymer (b) may be crosslinked, esp. by O-, S-, N-, urea-, urethane- or -CH2-bridges between the polymer chains. The adhesives can be used for making adhesive tapes, e.g. for packaging industry. Copolymerisation with (a) increases degree of crosslinking and improves creep-strength, e.g. to >10 min. The use of terphenol as (a) also increases adhesiveness of the melt adhesive. The use of crosslinked (b) having a low degree of crosslinking increases the adhesive properties of the melt adhesive. On the other hand, creep-strength increases with a high degree of crosslinking.

Patent ES-473459-A1 (ES)
Title: New process for preparing pharmaceutical, cosmetic or diagnostic formulations
IPC: B01D43/00
Filed: 1978-09-18
Abstract: The process produces pharmaceutical, cosmetic or diagnostic formulations by the freeze drying of one or more substances in solution or in suspension in a solvent or a mixture of solvents. The solution or suspension is locally and progressively cooled in a controlled manner while agitating so as to produce microcrystals of solvent which are put in suspension in the remainder of the liquid until there is obtained a high-viscosity microcrystalline complex system comprising essentially isolated microcrystals of solvent in intimate mixture with interstitial liquid phases having a high concentration of the initially present substances. The microcrystalline complex system is hardened by cooling and lyophilized. This process permits the obtainment of lyophilized formulations having a higher dissolving or dispersing rate and lyophilized compositions of normally incompatible substances.

Patent ES-476438-A1 (ES)
Title: An alarm unit
IPC: G08B13/22
Filed: 1978-12-28
Abstract: An alarm sensing network comprises a plurality of normally-closed switches (1) connected in series between first and second terminals (B1 and B2) of an alarm unit and a plurality of normally-open switches (2) connected in parallel between the first terminal (B1) and a third terminal (B3) of the alarm unit. In the event of an abnormal condition (i.e. one of the normally- closed switches opening or one of the normally-open switches closing) a warning is raised e.g. by sending a loud-speaker (HP). An abnormal condition is sensed by a current flowing through one of two bridges of series- connected resistors (R17, R18 and R19 or R37, R38 and R39). In each case a current flow through the bridge turns on a transistor (T7 or T9) connected to turn on a transistor T8 which supplies power to an alarm sounding circuit including the loud-speaker (HP). The second and third terminals are connected to the rest of the unit via diodes (D6 and D7) A plurality of alarm units may have their corresponding first, second and third terminals interconnected so that they share a common sensing network. The arrangement is such that, even without the diodes, there is little danger of a false alarm at one unit due to a low battery at another unit.
