Patent ES-346999-A1 (ES)
Title: Selective Signalling System
IPC: H04Q9/14
Filed: 1967-11-10
Abstract: One of a number of field stations is called by transmitting a code corresponding to the desired field station, the code being received at the field station and compared bit-by-bit with a locally generated code unique to that station. The signals may be transmitted by radio, a laser beam or a line. At the field station they are applied to a pulse shaper, 114, Fig. 2, to obtain a series of seven square pulses, the first being a start pulse, the next five being the code and the last being an end pulse. The start pulse passes on lead 116 to start a clock oscillator 120 which, through a driver 124, causes a " 1 " bit in the first place of shift register 126 to step through the stages giving successive signals on outputs p, q, r, s, t. In code plug 128, two of these terminals are connected to the corresponding terminals P, Q, R, S, T which are connected, together with the output from the first stage of the shaft register, to Or gate 146. The output y consists of a series of pulses, the start pulse and two of the next five possible pulses, being the station code. This signal is compared in Exclusive-Or gate 122 with the incoming signal x on lead 118. If there is disagreement an output is given by gate 122, which passes over line 144 to reset circuit 136, stopping the oscillator 120 and resetting the shift register to the initial condition. If there is agreement the seventh clock pulse moves the " 1 " bit in shift register 126 into the seventh position to give an output on lead 130. This resets the circuit ready for the next part of the operation and sets flip-flop 152 the output of which restarts the oscillator 120 to cause the code to be read out again from the code plug 128. A switch 155, enabled by flip-flop 152 causes the code y to be transmitted back to the central station to indicate that the selected station has responded. In another embodiment the calling signal consists of 4 decimal digits each represented by five bits, two of which are present.

Title: Thermally deformable fastening pin
IPC: F16B19/00
Filed: 1973-11-08
Abstract: A fastening pin for use in connecting printed circuit boards or the like constructed of concentrically arranged split tubes or layers of material having different thermal properties. One tube is made from a heat recoverable metal alloy, that is, a metal alloy that can be caused to exhibit a decided reduction in strength and be deformed when it passes through a transition point in a first direction and a reverse change in dimension and increase in strength when it passes through the transition point in the opposite direction. The other tube is resilient and has spring like characteristics so that it has sufficient strength to move the first tube of material when the latter is in its low strength condition, and sufficient flexibility to be moved by the first tube of material when it changes dimension. The pins are formed by taking split cylinders of each material and force fitting the tube of heat recoverable metal inside the tube of spring metal. Also disclosed is a similar pin wherein two layers of heat recoverable metal are used to sandwich a layer of spring like material, and a sectionalized pin which permits substantially independent motion by different segments thereof.

Title: Hydrostatic transmission system for articulated vehicle
IPC: B60K17/356
Filed: 1975-04-11
Abstract: A hydrostatic transmission drive system for an articulated vehicle in which an operator controlled reversible variable displacement pump effects through flow divider means positive traction at one wheel under full pump pressure irrespective of a loss of traction on any other wheel, such that during straightahead steering each drive wheel operates continuously at a fixed proportion of total fluid volume and at pump discharge pressure. During articulation of the vehicle for steering the flow is proportionalized to the inside and outside wheels to effect differential wheel speeds at front and rear pairs thereof as required for non-scrub steering at all available steering angles. under particularly adverse circumstances, such as deep mud, the vehicle is capable of "snaking" its course by zig-zag steering under traction.

Title: Flocked yarns - produced by passing adhesive coated yarns over bed of flocked particles overlaying positive electrode the yarns forming negative one
IPC: D02G3/40
Filed: 1975-06-27
Abstract: Yarns or filaments are flocculated by passing adhesively coated yarns which are connected to a negative or earth potential above a single positive electrode arranged below a cloud of diaelectric flocculating particles, which in consequence of the electrostatic field produced between the yarns and electrode are attracted to the yarns. Yarns with uniformly distributed particles are produced without rotation of the yarns. Preferably the electrode is adjustable w.r.t. the yarns such that the distance is progressively reduced in the direction of movement of the yarns. Adjustment brings about differential acceleration of the flocculating particles, the acceleration being highest at the outlet from the electrostatic chamber.

Patent ES-442601-A1 (ES)
Title: Electronic transmission dynamometer
IPC: G01L3/10
Filed: 1975-11-13
Abstract: A dynamometer in which a signal generator provides a repetitive signal of adjustable frequency, to record-playback heads fixed adjacent to similar magnetic recording mediums that are non-magnetically mounted and spaced axially apart on a drive shaft rotating without loads. Simultaneous recordings are made by the heads on the mediums and the signal generator switched off. With the rotating shaft loaded, the recordings are played back by the axially spaced recording-playback heads, and a phase difference between the recorded signal from each head is a measure of torque on the shaft. The frequency of recorded signal from either head is a measure of the speed of rotation of the shaft. The playback signals drive an electronic computer of well know design that multiplies the measure of torque by the measure of speed of rotation to provide a voltage proportional to shaft horsepower to a voltmeter that may be calibrated to read directly in horsepower given the elastic modulus of shaft material and shaft dimensions. In an excessively vibrating shaft, record-playback heads are mounted rigidly with respect to each other on a cradle that rides on the shaft and is held in place against turning with the shaft by springs attached to convenient fixed points.
