Patent ES-485969-A1 (ES)
Title: Test circuit for synchronously operating clock generators.
IPC: G06F1/04
Filed: 1979-11-15
Abstract: In a data processing or transmission system which includes at least two synchronized clocks, for example-T-rings A and B which generate timing pulses Tai and Tbi for microinstruction execution, synchronism is checked by logic circuitry which receives pulses from the clocks. At least one of the pulses is delayed by one or more pulse period durations ti. The logic circuit output signal is used as an input to an indicator latch which is periodically set by an independent check oscillator or clock. In a preferred embodiment, the delays are introduced by master-slave flip-flops, which receive predetermined combinations of the T-signals and set by the independent check clock. Several delay latches and associated AND gates may be used for different logical combinations of delayed and undelayed T-signals. This scheme can easily be expanded to accommodate more than two synchronously operating clocks. These circuits check not only the instantaneous synchronism of the clocks, but also the correct sequencing of clock pulses. The check is also feasible if the T-ring counters are operated with a variable number of clock pulses per microinstruction execution.

Patent ES-8200656-A1 (ES)
Title: Process for preparing polysulfide chain terminator.
IPC: C08G75/00
Filed: 1980-12-16
Abstract: Process for preparing a mixture of hydroxyl-containing di- and trisulfides, from either 2-mercaptoethanol or 3-mercaptopropanol, directly in two steps, without the formation of deleterious by products. Precise control of process conditions (a) in a first step in which the disulfide is formed, includes oxidation of mercapto-lower alkanol with a stoichiometric amount of H<u2>uO<u2>u while maintaining the pH and temperature of a relatively dilute aqueous reaction mixture within a specific narrow range and, (b) in a second step in which a predetermined portion of the disulfide is converted substantially exclusively to the trisulfide, requires controlled heating of the reaction mixture to a temperature not to exceed 100'C. The process may be carried out in a single reaction vessel, and directly yields a preselected distribution of disulfide and trisulfide in the mixture. The mixture is especially useful as a chain terminator in the preparation of hydroxyl-terminated liquid polymers having an aliphatic polymeric backbone and sulfide linkages near the terminal portions of the polymer molecule (referred to as "HTPS" polymers).

Title: Retroreflection plate.
IPC: G02B5/124
Filed: 1980-11-27
Abstract: A retroreflector plate and a method for its manufacture are described. The retroreflector plates consist of a transparent plate with a reflective rear side, the front side of which comprises adjacently disposed, curved light incidence surfaces, and the rear side of which comprises adjacently disposed, curved reflection surfaces, in which case the optical axis of each individual light incidence surface coincides with the optical axis of a respective reflection surface. The retroreflector plates are distinguished by the fact that, when the light incidence surfaces or the reflection surfaces are projected perpendicular and parallel onto the plate surface, as the plane of horizontal projection, the outlines of the reflection surfaces comprise different surface content, when compared with each other and with the light incidence surfaces, or, the outlines of the light incidence surfaces and their respective reflection surfaces substantially comprise the same surface content, while having different contour shapes. The retroreflector plates are further distinguished by the highest possible luminous values and at the same time by a wide angle range of reflection.

Title: Dryer felt fabric
IPC: D21F1/00
Filed: 1982-01-28
Abstract: A method of stabilizing a dryer felt fabric for a papermaking machine, comprises including in the cross- machine direction synthetic polymeric yarns 18 of relatively low softening point. Upon heat-setting the fabric 10, the yarns 18 of low softening point relax and take on the configuration of the weave. Upon re-solidifying the softening yarns 18 lock in with the remaining yarns of the fabric at cross- over points. As shown, the fabric 10 comprises two layers A, B of cross- wire yarns 12 which are bound together by interwoven lengthwise yarns 14. Preferably, the yarns 12, 14 are monofilaments of polyesters, polyamides, polyaramids or polyolefins which do not absorb high proportions of moisture. Stuffer pick yarns 18 partially fill voids 16 between the layers A, B and are made of a thermoplastic polymer having a substantially lower softening point than the yarns 12, 14, e.g. spun yarns of polypropylene. Heat setting may be carried out at temperatures of 200-380 DEG F (93.3-193.3 DEG C) for 15-60 minutes.

Title: Optical display cell and a method for its manufacturing including a gas cloud with monodispheres
IPC: G02F1/1339
Filed: 1982-11-03
Abstract: An optical display cell of the liquid crystal type has two parallel substrates separated from each other by means of ball-shaped monodisperse particles, which are distributed homogeneously and separately across the entire area of the substrate. The dimension of an intermediate layer of liquid crystals between the substrates is, therefore, determined by the diameter of the particles. The particles are distributed across the substrate in a room, which is shielded against dust and foreign particles, by means of pressurized gas, which creates turbulence in the room. The ball-shaped particles are distributed homogeneously across the entire area of the substrate.

Title: Automatic adjusting device for a brake
IPC: F16D65/54
Filed: 1983-12-01
Abstract: A strut (40), whose effective length depends on the relative positions of two strut portions (42,44) adjustable with respect to each other is connected in parallel with a brake actuating mechanism (18).
