Title: Improvements in or relating to apparatus for analogical measurement of distances by means of ultrasonic pulses
IPC: G01S7/52
Filed: 1967-02-09
Abstract: In a system for measuring the separation of two points in a medium by determining the peak amplitude of a staircase waveform whose generation is initiated at the instant of emission of an ultrasonic pulse at one of the points and terminated on receipt of the echo obtained by reflection of this pulse at the other point, the measurement is made independent of variations in the ultrasonic wave propagation velocity by ensuring that all steps in the staircase waveform have the same amplitude and a duration which is inversely proportional to the propagation velocity in the medium. In the Fig. 1 embodiment, clock pulses of constant amplitude from generator 6 and shaper 5 are generated during the propagation time of an ultrasonic pulse from transducer 2 and applied via capacitor 10 to an analogue integrator comprising capacitor 14 and negative feedback amplifier 11. The peak value of the staircase voltage on capacitor 14 is converted to a distance indication at 17 and 18. The clock pulse frequency is that of oscillations maintained by an amplifier 9 whose input and output are connected to a pair of auxiliary transducers 7, 8 spaced a predetermined distance in said medium.

Title: Oscillator apparatus for generating tone frequencies
IPC: H03B5/12
Filed: 1967-12-22
Abstract: In a signal generator of the type in which the frequency of an oscillator is varied by selecting an appropriate tap on the inductance in an LC circuit, a source of potential is directly connected to the capacitor of the LC circuit and is directly connectable through switching transistors to the tappings on the inductance. The Figure shows a dual tone generator for multi-frequency telephone signalling. A pair of transistors 66 and 75 oscillate when enabled at frequencies determined by the settings of their respective LC circuits 60-1 to 60-4 and 70-1 to 70-4, and the combined output is applied via an emitter follower 100 to an output transducer 104 coupled to the microphone of a telephone handset. To select a pair of frequencies, a single key of a set 96-1 to 96-10 is depressed supplying earth potential to one column of a diode matrix. This potential is applied via two row conductors to the base of one transistor of a set 76 to 82 and to the base of one transistor of a set 84 to 90. These transistors are thus switched to conduction supplying an enabling potential to the corresponding taps 60-1 to 60-4 and 70-1 to 70-4 causing the circuit to oscillate at the selected frequencies.

Patent ES-356236-A1 (ES)
Title: Breechcase for firearm
IPC: F41A15/16
Filed: 1968-07-17
Abstract: An automatic or semi-automatic firearm comprises a substantially cylindrical breech mechanism 1 arranged to reciprocate in a breech case 2 which has, towards its rear end, a portion internally and externally of rectangular cross-section. A spent cartridge ejection opening 7 is provided in one, 3, of the small sides of the portion and the large sides are each provided with a cartridge introduction opening 8 which has two guide surfaces 42 for guiding the breech mechanism 1 and a counter recoil spring 10 in their movements. The four guide surfaces 42 are situated on a common cylinder of revolution whose axis is parallel to the axis of the firearm barrel 16. Two cartridge feed mechanisms (9, Figs. 2, 4, not shown) are mounted one on each side of the firearm one being moved into a cartridge feed position in which cartridges pass through the corresponding cartridge introduction opening 8 to be brought into the chamber 57 of the firearm by the breech mechanism 1 on its return to the firing position. In the construction shown, the breech mechanism 1 comprises a breechblock 11 locked by rotation, a casing 18 formed of two shells and slidable without rotation in the breechcase 2, and a damping device 19. A firing pin 21 within the breechblock 11 is connected to the casing 18 by a spindle 20. The ends of the spindle 20 each carry a roller which co-operates with a skew to effect rotation of the breechblock during its reciprocations (Fig. 4, not shown). The initial cocking mechanism comprises a chain actuated by a crank through a spindle 31. The breechblock 11 carries an extractor 35 and is provided diametrically opposite with a groove 36 for the passage of an ejector 33. The extractor 35 is maintained in position by a leaf-spring 37. The fastening and control of the feed mechanisms are arranged as in Specification 1,191,856 and the cartridge belt advancement mechanism in each feed mechanism may be of the type described in Specification 963,119. The drive of the feed mechanisms comprises a fork 89, one limb of which co-operates with a roller of a lever of the feed mechanism in the cartridge feed position while the other limb is dissociated from the equivalent lever of the other feed mechanism (Figs. 2, 4, not shown). The fork 89 reciprocates with the barrel 16 and sleeve 15 assembly, the movement of the fork being damped in the recoil movement by a piston assembly 99, 100, 105 working in a cylinder in the fork. The pistonrod 101 merely abuts a member 102 of the casing and thus the movement of the fork is not damped by this arrangement on its return stroke. The ejector 33 of the firearm has a cartridge striking surface 109 and a projection 112, the projection firstly urging the spent cartridge to pivot upwardly before the striking surface ejects the cartridge through the ejection opening 7. A spring-loaded sear 26 may be withdrawn and held out of the path of the breech mechanism 1 by cam 67. A damping spring 66 is also provided for the sear.

Patent ES-376207-A1 (ES)
Title: Electrical connector assembly
IPC: B29C37/00
Filed: 1970-02-04
Abstract: A sealed flexible joint between a tubular member 14 and an electric cable 10 passing therethrough is made by shrinking a heatshrinkable sleeve 19 on both members and cable whilst trapping ring 20 of semi-thermoplastic sealant material between the sleeve 19 and the member 14. A sealed housing for electrical connections between cables 10 utilizes such joints between end caps 2b having tubular portions 14 through which cables 10 pass. In this embodiment the sealant material 22 coats the inner surface of the heat-shrinkable material 19, which may be integral with the end cap (Fig. 2, not shown), and may be stepped to provide portions (3, 3a) of different diameters for accommodating cables of different diameters. Annular cable cleats, such as 23 having inwardly-directed barbs 24, or comprising a plurality of metallic or metal coated plastics planar members flexibly connected together and provided with ribs (Fig. 11, not shown), may be provided on the cables so as to be sandwiched between the cables and the material 19. Barbs may also be provided on the tubes 14. Those heat-shrinkable members not used may be left capped (Fig. 2) The end caps are sealed to the sleeve 1b to produce either a breakable seal, in which case an elastomeric material 6b is compressed between end cap portion 4b and sleeve 1b by a clamp 7b, or a permanent seal, in which case a metal grid (Fig. 6, not shown) replaces the material 6b and is heated to cause sleeve 1b and portion 4b to flow together. In both cases a metallic back-up ring 5b preferably of aluminium, is used. Tie-rods 17 of plastics-coated metal are used to retain the two end caps in position although one end only of the sleeve may be used for cable entry, the other end of the sleeve being permanently sealed. The housing may be pressurized through a valve member (33, Fig. 1, not shown).
Patent ES-402501-A1 (ES)
Title: Pal-type color signal processing apparatus
IPC: H04N9/455
Filed: 1972-05-06
Abstract: Burst components of PAL-type encoded signal are retained with modulated subcarrier components as they are processed in 1H delay line assembly and delivered to respective demodulators. Reference oscillation phase to which R-Y demodulator responds is effectively reversed every other line, in response to PAL switch apparatus, in order to provide desired R-Y output in successive lines. Reference oscillation phase to which B-Y demodulator responds is alternated by quadrature switch apparatus between B-Y phase (applied throughout each line interval) and R-Y phase (applied during each inter-line blanking interval). A first gating circuit, coupled to the output of the B-Y demodulator, selects that portion of the B-Y demodulator output developed during the burst interval for passage to integrating and amplifying means in order to develop an AFPC voltage for phase control of the local reference oscillator. A second gating circuit, coupled to the output of the R-Y demodulator, selects that portion of the R-Y demodulator output developed during the burst interval for passage to ACC and color killer circuitry. During color operation (enabled state of bandpass chrominance amplifier) the ACC circuiry develops a control current from the second gating circuit output that adjusts the chrominance amplifier gain in a direction appropriate to maintaining burst amplitude substantially constant at a level set by a manual chroma control. The color killer enables the chrominance amplifier for color operation only when the gated R-Y output indicates by its amplitude the presence of a burst in the received signal and by its polarity the correct switching mode for the PAL switch. Unless such circumstances are present, the color killer disables the chrominance amplifier during each line interval the killer is keyed, however, to enable the chrominance amplifier during each burst interval so that recovery from the disable state may be effected when appropriate. The color killer circuitry also passes a reset pulse to the PAL switch in the absence of a correct mode indication in the gated R-Y output. The color killer circuitry further serves to control the effectiveness of a subcarrier trap for the receiver's luminance channel, removing the trap during line intervals of monochrome operation.
