Patent ES-374972-A1 (ES)
Title: Noncontacting motion sensor
IPC: G01S13/58
Filed: 1969-12-27
Abstract: To determine a component V X , Fig. 2 of the velocity V of a moving object, the doppler shifts imparted to two beams of radiation, incident on the object along position vectors E 1 and E 2 having an angle bisector orthogonal to V x , and scattered along a common direction E s1 are differenced, said difference being proportional to said velocity component. The measurement is independent of any movement of the object perpendicular to V x . Thus to detect the velocity of a metal sheet 10, Fig. 3, leaving a mill and liable to wrinkling (perpendicular movement), a laser 18 emits a coherent beam which is split into two beams 11 and 13 which intersect at a common point 15 on the sheet. The beams make equal angles 0/2 with the perpendicular to the sheet, so that V x is the velocity of the sheet. The scattered radiation from the two beams is detected at 23 and therein mixed to produce the differential doppler frequency. Beam splitting semi-transparent and totally reflecting mirrors 22 and 24 may be incorporated in one solid optical block Fig. 4 having a semi-reflective face 30 and a totally internally reflecting back surface. As an alternative, a single beam of radiation 47, Fig. 5 may be incident on the sheet and the two differently scattered radiations detected by equally angularly offset means 48 and 52, 48 being a mirror and 52 being an optical mixer directing the combined radiation to the photodetector 54.
Patent ES-375398-A1 (ES)
Title: Volumetric valve
IPC: G01F15/00
Filed: 1970-01-14
Abstract: A valve for reversing the flow through a water softener containing ion-exchange resins has an impeller 72 which is driven by the flow of water from an inlet 7 through an apertured seat 30, chamber 42, tangential aperture 68, tangential aperture 74 and pipe 5 into the softener from where it flows via a pipe 3, a check ball valve 20, and chamber 12 to a soft water outlet 9. The impeller drives via a reduction gear 76 a disc 108 on which are mounted two adjustable pins (110), 112 that engage the end 62A of a pivoted lever 62 having a forked end 62B, 62C. A lug 57 on an arm 56 rigid with a slide valve 54 is arranged between the arms of the fork so that after a certain volume of water has passed through the softener one of the pins (110), 112 will move the lever 62 to open the valve 54 and exhaust chamber 40. A spring 64 connected to the lever 62 acts as an overcentre device to quickly move the valve to the end position. Opening of valve 54 permits the pressure differential across diaphragm 36 to overcome the spring 44 and move closure member 32 off its lower seat onto its upper seat 30. Water from inlet 7 can not only thus pass directly to the outlet 9 but also via passage 22, nozzle 24, and Venturi 26 into the softener via pipe 33. The passage of water through the nozzle 24 and Venturi 26 takes in brine from a separate container connected to 28. The brine thus flows through the softener and out via pipe 5, tangential apertures 74, 68, chamber 42, restriction 48, opening 50 and open valve 54 to exhaust. The impeller is thus rotated in the reverse direction as is disc 108 but at a different speed since the reduction gear 76 has a different transmission ratio in the two directions of rotation. After the predetermined volume of flow lever 62 is operated to close the valve 54 and water softening is assumed once more. During this phase water can pass through connection 28 to a salt containing vessel via a floating ball check valve (115) and a float-operated valve (119) to produce brine for the following cycle. The reduction gear 76, Fig. 12 drives the output gear 102 in one direction of rotation through gears 80, 82 fast on their shafts, gear 84 free on shaft 86 and one-way spring clutch 100 and in the other direction of rotation through gears 80, 88, free gear 90, one-way spring clutch 98 and gears 94, 96 fast-on their shafts 92, 86 to ensure a different transmission ratio for each direction of rotation. In a modification the pins (110) 112 on the disc 108 actuate an electromagnetic mechanism for operating the valve 54.

Patent ES-423728-A1 (ES)
Title: System for transferring wide-band sound signals
IPC: G10L19/00
Filed: 1974-02-28
Abstract: A system for transmitting wide-band signals over a narrow band by directly transmitting low frequency range signals and transmitting amplitude information of partial upper frequency ranges on pilot frequencies is made compatible with existing receivers by making the pilot frequency signals imperceptible in ordinary receivers through the use of a phenomenon known as the masking effect. This is achieved by positive modulation of the pilot frequencies and attentuation to a level 10 db below the level of the low frequency range. If sequential transmission is used, a low level sync signal is produced that does not exceed the signal-to-noise level in existing receivers and is therefore suppressed. In the receivers of the present invention, the low level sync signal is selectively evaluated for control and synchronization of a clock generator but is suppressed below the signal-to-noise ratio of the output and is therefore made inaudible. The sync signal is further processed to control the gain of a modulated pilot signal amplifier and to automatically switch off the upper frequency range signals in the event of sync signal failure or synchronization failure.

Patent ES-476275-A1 (ES)
Title: Method and an arrangement for the manufacture of casings
IPC: B29C53/56
Filed: 1978-12-22
Abstract: In the packaging field certain types of packages are manufactured from pre-shaped, cylindrical casings made from a heat-shrinkable laminate. The casings are formed by winding a material sheet around a mandrel and subsequent sealing together of the overlapping ends of the sheet. However, because of the stiffness of the material the leading end of the sheet protrudes tangentially from the mandrel during the winding and prevents an accurate adaptation of the material sheet to the surface of the mandrel. According to the method and arrangement of this invention this disadvantage is avoided in that the leading end of the sheet is pre-heated on the side facing the mandrel to such a degree, that the shrinking is initialled. The shrinking of one side only results in that the leading end of the material sheet is given a curved shape with a radius that coincides with the radius of the mandrel, and consequently the leading end is no longer an obstacle to the winding.
