Patent ES-338077-A1 (ES)
Title: Code translator controlled by the most significant digit of a code group
IPC: H04L25/49
Filed: 1967-03-15
Abstract: A translator for binary coded signals includes means to detect the binary condition of the most significant digit of the signal and means to complement the remaining digits of the signal if the most significant digit is a binary "1". In the embodiment described if the most significant digit fed from a source 22 is a "1" it is fed via AND gate 4 during a first time interval t1 to set a bi-stable device 2 to its "1" state, the bi-stable device priming a further AND gate 5. During a second time interval t2 when the second digit of the code is supplied to the apparatus a bistable device 3 is set to its "1" state so that AND gate 6 is disenabled and AND gate 7 is primed and the remaining digits are fed through an inverter 9 and the AND gate 7 to an OR gate 8. If however the first digit is a "0", AND gate 4 is disabled and an AND gate 6 is primed by the zero output from bi-stable device 3 to feed the signal from the source 22 to the OR gate 8.

Title: Guide plate for magnetic tape
IPC: G11B15/61
Filed: 1967-06-28
Abstract: A plate 25 for guiding a magnetic tape helically around a drum 7 has its ends formed with deflecting surfaces 11, 111 for guiding the tape to, and away from, the drum, so that in, e.g. helical wrap video tape recorders, the tape approaches and leaves the drum in one plane, thereby allowing the spools 2, 16 to be coplanar. Accordingly, the drum 7 is tilted at an angle # to the base 1 and the tape is wrapped around the drum for 180 degrees at a pitch angle #, magnetic heads (9, Fig. 2, not shown), rotating in a slot in the drum. Equations are derived in which the inclination of the deflecting surfaces 11, 111 to the base 1 and the angle # through which the tape is deflected by the surfaces are related to the angles # and # defined above. As shown, the tape 3 is guided over tensioning arm 4, roller 5, erase head 6, drum assembly 7, audio and sync. head 12, 121, between capstan 13 and pinch roller 14, and over tensioning arms 15.

IPC: B31B19/00
Filed: 1968-10-15
Abstract: A machine for making envelopes of different sizes comprises a frame 14 defining a path 15 of envelope blank travel and a series of clutch activated mechanisms disposed along the path 15 to sequentially operate on the blanks, some of which are independently adjustable by rotation of a common shaft 32 in response to blank dimensional changes whilst the others are adjusted by driving members 16 themselves driving by a main drive motor 2. The shaft 32 adjusts mechanisms, e.g. a flap separator 17, Fig. 2, via intermeshing bevel gears and chains and sprockets, each mechanism having an electrically operated clutch for engagement or disengagement with the shaft 32 for selective mechanism adjustment. Rotation of the shaft 32 is controlled by a master motor 102 which, as with the clutches, receives signals from a computer 103 via their respective conduits 104, 105 in response to blank (envelope) dimensional changes. Handles may be used for manual " fine tuning " of the mechanisms.

Title: Miniature high-speed electric toy racing vehicle with rechargeable battery
IPC: A63H19/24
Filed: 1970-05-18
Abstract: A toy racing vehicle, e.g. a car, comprises a light plastic body and chassis, two wheel assemblies, a high speed (preferably three-pole) motor 75 directly driving one of the wheel assemblies, a rechargeable battery 37, a switch between the battery and the motor and means whereby connection may be made with a suitable plug 181 to recharge the battery. Figure 8, which is a section along the line 6-6 of Fig. 3, shows the switch mechanism in the off position. In this position the centre part 133 of one of the contacts 107 between the battery and the motor is raised by a projection 157 on the sliding switch member 151 so that the end 131 of the contact is lifted away from the corresponding motor terminal 89. Figure 9 shows the recharging position in which the tip of a coaxial plug 181 makes a connection with the contact 107, while lifting it to disconnect the motor, and the sleeve of the plug makes a connection with the other contact 105 through which it passes by hole 119. In order to prevent damage to the battery by recharging if it is inserted the wrong way round the negative contact 105 has two projections 113 and 115 so that in that event the battery is shorted. An absorbent pad (149) is provided adjacent to the cap of the battery to absorb any leakage. A further feature of the invention is the front suspension system in which a resilient axle 53 is held between a flexible arm extension 55 of the chassis and projections 57 at the side of the chassis so that the ends of the axle can flex both upwardly and downwardly.

Title: Apparatus for splicing conductors
IPC: H01R43/04
Filed: 1972-11-07
Abstract: An apparatus for a solderless splicing of insulated electric conductors includes a jaw assembly and, on each side thereof, a backup support provided with parallel conductor guides aligned with the length dimension of the jaw assembly. The jaw assembly is provided at both sides with cutters, the cutting zones of which intersects the axis of one conductor guide at one side of the jaw assembly and the axis of the other conductor guide at the other side of the jaw assembly. A trough-shaped splicer is positioned in the jaw assembly and the two conductors are placed in the splicer so that they lie in the conductor guides side-by-side, but oppositely oriented. As the jaw assembly executes its motion to compress the splicer, the end portions of the conductors projecting beyond the jaw assembly are severed on both sides by the cutters and then, before the jaw assembly fully compresses the splicer about the conductors, the jaw assembly causes, by virtue of its motion, a longitudinal displacement of the conductors in opposite direction within and with respect to the splicer so that the bare cut end face of each conductor is withdrawn into the splicer.

Patent ES-421628-A1 (ES)
Title: Enthalpy calculating device for steam
IPC: G01N25/60
Filed: 1973-12-19
Abstract: The enthalpy calculating device includes a function generator which receives two signals, one representative of either the temperature or pressure property of the steam and the other representative of the enthalpy of the steam for the particular state of the steam. The function generator then emits an output signal corresponding to the other of the temperature or pressure property of the steam. The device also has a controller means composed of a comparator and integrator or an integral action controller. This latter means receives the output of the function generator and compares it with the actual value of the "other" property of the monitored steam. If there is a difference, the output of the controller means is corrected accordingly. This output serves not only as one of the input signals to the function generator but also as the output signal of the device to control the flow of feed water.

This is accomplished by having vertically spaced clamping portions on the side of the knee, each clamping portion containing a part of the ways, which ride in the dovetail on the column, separated from adjacent portions of the knee and providing a screw which, when operative, will spring said clamping portion inwardly to clamp portions of the ways on both sides of the knee against both sides of the column dovetail.
Patent ES-428528-A1 (ES)
Title: Intrusion detection system
IPC: G08B13/26
Filed: 1974-07-23
Abstract: A wire comprised of an electrical conductor enclosed within insulation, is loosely positioned relative to an electrically conductive member. This combination is positioned to monitor disturbances caused by the intrusion of the protected area. The relative movement of the wire and the electrically conductive member caused by intrusion disturbances produces an electrical signal which is attributable to a capacitance change. The signal can be realized from either the electret characteristic of the wire or it can be realized by the application of a d-c bias voltage to the combination. A signal developed by the combination in response to a mechanical disturbance includes a low frequency and a high frequency component. The low frequency component, attributable to a "strain mode" of operation, developed by the displacement of the wire relative to the electrically conductive member by mechanical deflection of the conductive member whereas the high frequency component, attributable to an "acceleration mode" of operation, results from the vibration of the wire relative to the conductive member. The high frequency component code is comparable to a "ringing" condition much the same as is experienced by an accelerometer.
