Patent ES-337440-A1 (ES)
Title: Container for biological cultures
IPC: C12M1/24
Filed: 1967-03-02
Abstract: A generally polygonal cross-section container 1, has within it, a mesh 7, e.g. of plastics or metal, which holds a solid culture medium 6 in place after it has first been allowed to solidify with the container horizontal, and a neck 4. The neck 4 may be laterally displaced towards a wall 21 to facilitate removal of the culture by, e.g. a rod, Fig. 16 (not shown). The mesh 7 is retained in position by pressure of its ends against the side walls 3. It may extend over the side walls 3 to the wall 21, Fig. 7 (not shown). The mesh 7 may be thermoset in a form which when positioned remains so by expansion against the walls, or it may be held in outwardly projecting vertical furrows (8e), Fig. 12 (not shown), at the corners of the wall 2. The corners opposite the furrows (8e) may be bevelled. In a further modification, an internal transverse ridge (12), Fig. 16 (not shown), is provided at the top edge of the wall 2 to limit the area of spread of the culture medium 6. The surfaces of the wall 2 are perfectly parallel to avoid optical aberrations when viewing the culture.

Title: Improvements relating to the counting of neutrons
IPC: H01J47/12
Filed: 1967-05-18
Abstract: In a neutron counter using radiative capture, the (n, y) reaction provides radioactive isotopes emitting beta and gamma radiation. The reaction takes place within a Geiger-Muller type counter which detects the internally induced beta and gamma radiation. The counter has a halogen gas filling and comprises concentric electrodes, incorporating the rhodium isotope Rh 103, which after neutron activation produces Rh 104 and Rh 104 m. The first decays with a beta emission and a half-life of 44 seconds and the second has a gamma emission and a half-life of 264 seconds.

Patent ES-368035-A1 (ES)
Title: An outgoing trunk signalling and supervision arrangement
IPC: H04Q3/00
Filed: 1969-06-04
Abstract: In a system in which, for an outgoing call, a calling subscriber is connected via a line frame, an originating junctor and a trunk frame to an outgoing trunk circuit and in which a sender is connected to the originating junctor during outpulsing, supervision of the connection is vested in the junctor during sending and then in the trunk circuit when sending ceases and the sender has been disconnected. Crossbar switches are used in the line and trunk frames. The system is distinguished from the No. 5 crossbar wherein the sender is connected to the outgoing trunk, and originating junctors are not utilized (Fig. 1, not shown). Details.-It is assumed that the connection is completed up to an outgoing trunk 34 in which a relay ON is operative to an earth on the sleeve lead S. When sufficient digits have been accumulated in a register sender 35, a relay D is brought up in the originating junctor 32 whereby a holding earth for the hold magnets H in the trunk frame and for the relay ON in the trunk is applied to the sleeve. The digits outpulsed from the sender are passed over the Tip and Ring leads to a special signalling path associated with the trunk. When sending ceases, relay D is dropped thus removing earth from the sleeve and allowing low resistance relay EP in the trunk circuit to come-up in series with ON (which is slow to release). A resistive holding earth is thus reapplied to the sleeve via EP until such time as full ground is applied from the calling or called party's supervisory circuit. EP also switches through the talking path at its contacts EP1, EP2.

Patent ES-402039-A1 (ES)
Title: Digital slip frequency control circuit for asynchronous dynamo electric machines
IPC: H02P23/08
Filed: 1972-04-24
Abstract: A control pulse generator is connected to control the gates of thyristor-type inverter circuits supplying an asynchronous dynamo electric machine with a-c power from a d-c source. The slip frequency is determined by a slip frequency pulse generator supplying pulses at a pulse repetition frequency (PRF) representative of a command value, in a feedback circuit including a tachometer generator supplying pulses at a PRF representative of speed of the machine pulses are applied to a bi-directional counter, the count in the counter controlling the control pulse generator. To prevent simultaneous input to the forward and reverse terminals of the bi-directional counter, a clock pulse source of predetermined frequency which is higher than the highest PRF expected is connected to a time-scanning and division network interconnecting the outputs of the various pulse sources and the counter so that pulses will be applied to the counter only as controlled by the clock pulse source. To enable the control pulse generator to have a wide range, for example between 50 to 30,000 Hz with controlled on-off ratio, a chopper applies positive and negative pulses to an integrator which is connected to a threshold amplifier, providing an output each time the threshold from the integrator is exceeded in either direction, the output controlling the operating rate of the chopper.

Patent ES-441427-A1 (ES)
Title: Method and apparatus for indicating a load placed on a load-carrying vehicle platform
IPC: B60P5/00
Filed: 1975-10-02
Abstract: This invention relates to a platform which can be displaced relatively to the frame side members of a load-carrying vehicle and which in the unloaded state is situated at the theoretical center of gravity of the vehicle load. A load placed on the platform results firstly in an increase in pressure in a tipping cylinder disposed at the center of gravity of the vehicle load and secondly a torque about the theoretical center of gravity of the vehicle load if the center of gravity of the load does not lie thereat. A signal proportional to such torque then controls a platform-displacing system to displace the platform towards the theoretical center of gravity of the vehicle load. The pressure rise occurring in the tipping cylinder forms an indication of the weight of the load and can then be noted and recorded.
