Title: Apparatus and method for mixing and pumping fluid explosive compositions
IPC: F42D1/10
Filed: 1971-02-15
Abstract: An explosive slurry comprising a solution of an oxidiser and suspended solid particles is prepared by feeding solid particles and liquid at controlled speeds to a mixer, withdrawing slurry from the mixer, pumping it to a delivery point, e.g. a borehole, and recycling part of the slurry through the slurry pump in order to control the density and other physical properties of the slurry. The liquid fed to the mixer may be a heated aqueous solution of ammonium nitrate and sodium nitrate containing guar gum as a delayed action thickener. The finely divided solid materials may be, for example, further oxidiser and aluminium powder and other fuels or sensitisers. Apparatus is described, Figures 1-8 (not shown) in which a petrol motor 25 drives, through a single main drive, a pump 119 for the aqueous solution, augers 169, 180 for feeding the solid materials at separately controllable rates, the stirrer in mixer 99, and slurry pump 93. The mixer and the slurry pump are interconnected so that they always work together. The composition of the explosive and the degree of aeration may be varied during pumping into a borehole. An air compressor is also provided to operate pneumatic controls and to pressurise a water tank for auxiliary liquid supply and cleaning. The apparatus may be mounted on a vehicle or may be removed and used in a mine tunnel. In an alternative arrangement, Figure 9 (not shown), the drive means and control are fluid operated by a master pump system.

Patent ES-439735-A1 (ES)
Title: Method and apparatus for reducing noise in pam time division networks
IPC: H04J3/00
Filed: 1975-07-24
Abstract: In pulse amplitude modulated time division switching systems, noise and crosstalk often result because the time division switches used to connect individual channels to a common bus are not perfect open circuits when they are in the off-state. The switches in the off-state possess a small parasitic capacitance which couples energy on the common bus to the channel resulting in a noise signal during time slots which are not associated with the channel. A method is disclosed for substantially reducing crosstalk and noise induced by stray capacitances without increasing the complexity of the time division switch. Each pulse on the common bus is converted into a bipolar pulse in which positive and negative portions have equal average values. In addition, the timing of each of the time division switches is modified to extract the desired signal by sampling the first portion of the bipolar pulse in the appropriate time slot for that channel, and rejecting the second portion of the bipolar pulse. The noise energy which is coupled from the common bus to the channel by stray switch capacitance during other time slots remains essentially bipolar in form and tends to cancel itself. The noise power at low frequencies is therefore substantially reduced. Apparatus is also disclosed for converting pulses on the common bus into the bipolar format required by the invention.

Patent ES-441726-A1 (ES)
Title: Mechanism for the automatic modulation of the direction and amplitude of movements of a member for feeding pieces to be sewn in a sewing machine
IPC: D05B3/02
Filed: 1975-10-13
Abstract: A mechanism for controlling the direction and amplitude of a cloth feeder in a sewing machine comprises a cam keyed on a spindle having a control button, said cam acting on an actuating arm of a control shaft of which the angular position determines the direction and amplitude of the feeder. By turning the control button, the cam angularly sets the actuating arm and hence the stitch length. When the button is turned to a given angular position, a cam profile thereon axially displaces a sliding rod to push a sliding pinion and bring a cam profile of the pinion into contact with an eccentric protuberance of the cam. The pinion is driven by the main shaft of the machine so that in said given position of the button it axially reciprocates the cam and hence automatically modulates the direction and amplitude of the cloth feeder to execute a special stitch.
Patent ES-447894-A1 (ES)
Title: Leak testing
IPC: G01M3/04
Filed: 1976-05-13
Abstract: A method of leak testing a transport vessel for radioactive material is disclosed. Tracer gas (helium) and pressurizing driving gas (nitrogen), the latter in condensed form, are introduced into the transport vessel when in open condition. The tracer gas is introduced in a plastic bag which occupies a major part of the interior of the transport vessel the through which the tracer gas diffuses at a low rate. The liquid pressurizing gas is introduced in a smaller vessel. After the transport vessel has been sealed, the tracer gas diffuses out of the collapsing plastic bag and the pressurizing gas boils off resulting in a pressurized tracer gas atmosphere within the transport vessel. The transport vessel is now examined on the outside with respect to any tracer gas penetrating out through possible leaks in the transport vessel.
Patent ES-449881-A1 (ES)
Title: Latch for a circuit interrupter
IPC: H01H1/52
Filed: 1976-07-16
Abstract: A latch for a circuit interrupter is provided wherein a movable member having a contact attached thereto is latched in a selected position by a spring member which is deflected by the movable member until a predetermined distance is exceeded at which time the spring member moves into a latching position with respect to a latching surface provided on the movable member. In its simplest form the latch uses a single piece of spring wire. As a movable member moves past, the spring wire moves aside and once the movable member has completely passed the wire, the wire springs back into place preventing the contacts from reclosing. A reset is provided which permits the contact arms to be closed by moving the spring member to one side. The disclosed latch is very fast acting, can be independently actuated for each phase, and can be positioned so as to not interfere with low current operation of the switching device on which it is employed.

Patent ES-452953-A1 (ES)
Title: Electric starter motor for an engine
IPC: H02K5/14
Filed: 1976-11-03
Abstract: A starter motor, particularly for internal combustion engines, has, as usual, a motor housing and a drive housing, the latter being provided with a mounting by which it can be fitted to the engine. However, instead of the usual method of joining together the motor housing and the drive housing, the motor housing is constructed to be rigidly secured to the drive housing and to the engine through the means by which the drive housing is attached to the engine. Thus, if the drive housing has an apertured flange for this purpose, the motor housing may also have a flange with corresponding apertures so that the same screw bolts or the like which hold the drive housing in place also hold the motor housing rigidly in position. The brushes are so located that they can be readily replaced without removing the starter.

Patent ES-470451-A1 (ES)
Title: Automatic head tracking system
IPC: G11B5/588
Filed: 1978-06-02
Abstract: During the reproduction of signals, a magnetic head (1) is moved along the recording track. An electrically deflectable securing means (2) for the magnetic head is fed an electric signal for deflecting the magnetic head. The deflecting signal is generated in a deflecting-signal generator (11, 12) according to the deflection of the magnetic head with respect to a position of rest. An envelope detector (5) serves for detecting the envelope of the signal which is emitted by the magnetic head. With a multiplying circuit (22), the detected envelope is demodulated synchronously with the deflecting signal, in order to obtain from it the tracking-error signal, which represents the deflection from the position of rest. In the adding circuit (8), the tracking-error signal and the deflecting signal are added.
