Patent ES-449725-A1 (ES)
Title: Multitone pushbutton dial phase shift scanning circuitry
IPC: H03B28/00
Filed: 1976-07-09
Abstract: In a multitone pushbutton dial array each switch in the array has a variable impedance coupling between a fixedly mounted conductive plate and a movable conductive plate spaced apart from the fixedly mounted plate. Digitally synthesized signals having a predetermined phase and frequency are sequentially and recurrently used to scan interconnected columns of movable plates in the pushbutton dial array. Signals having an opposite phase from the scanning signals are continuously applied to the fixedly mounted plates. When a pushbutton is depressed variable impedance coupled summation signals are produced and these signals have a phase which is opposite to that of signals coupled to the detector from an unoperated switch. The detected digital signals are used to generate digital multitone row and column frequency signals. These digital row and column signals are converted to analog form and are transmitted to a telephone central office as a dialed digit code.

Title: Double fruit crate cutter transport system - has chain conveyors pushing frames under guides past circular saws
IPC: B27M3/34
Filed: 1977-02-23
Abstract: An installation for cutting double frames into two single frames forming a stage in the manufacture of fruit crates, uses two circular saws (6) to cut through the vertical corner posts which have slats fixed to them, forming the sides of the crates. The frames are conveyed along parallel support tracks (5) by continuous chain conveyors (1) which have pushers (11, 12) suspended from them, which push the frames past the two circular saws. At the feed end, a double frame passes under an overhanging guide (9) which holds its steady as it is cut by the two saw blades, then the lower cut half is conveyed onwards under a second guide (10) mounted at a corresponding height. The upper cut half remains above the saw blades until pushed on by the next frame.

Title: Solids-liquid sepn. by flocculation esp. in hydrometallurgy - using two=stage flocculant addn. the first under agitation (PT 24.7.79)
IPC: B01D21/01
Filed: 1978-12-19
Abstract: A flocculation process, useful in hydrometallurgy to give excellent separation of leach liquor Aom insoluble residues and to recover liquor impregnated in the residues, comprises introducing into the suspension a major part (55-95% of the total quantity) of a flocculant, agitating the suspension to cover all the solids with the flocculant and then, after discontinuing agitation, adding the remainder of the flocculant. Instead of using very dilute flocculant solns. as in prior art (2 g/l, usually 0.5 g/l), more conc. solns (e.g. 5-10 g/l) or even undiluted flocculants can be used. This is useful when large amts of flocculant are to be added.
Patent ES-476515-A1 (ES)
Title: Device for removing lead particles from the exhaust gases of an internal combustion engine
IPC: F01N13/02
Filed: 1978-12-30
Abstract: Lead particles are removed from the exhaust gases of an internal combustion engine by deflecting the gases radially through holes (11) in the inlet pipe (10) to impinge on a wire mesh or expanded metal packing in a first annular chamber (12) for absorption of lead particles, the gases then passing through a chamber (8) in which a helical vortex flow is imparted to the gases by baffles (19-21), the gases then entering a convergent duct (24), backed by a further porous packing 26, where centrifugal separation of further lead particles takes place. The particles pass through slots 25 into packing 26 while a reversal of the gas flow direction occurs at the narrow end of duct 24, followed by axial straightening of the gas flow by radial partitions 28 before discharge of the gases through apertures 32 into an axial outlet pipe (18). The device also acts as a silencer.
Patent ES-476991-A1 (ES)
Title: Tomosynthesis of sectional images of a three-dimensional object
IPC: H04N7/18
Filed: 1979-01-19
Abstract: In a method of tomosynthesis of a body section, a body 51 is irradiated from different directions 44, 45, 46 to form a composite multiperspective image 50. A selected layer is tomosynthesised by multiple superposition 63, 64, 65 of the composite image 57, with appropriate lateral displacement related to the multisource geometry 43, on a display screen 68 so that corresponding image points relating to the selected layer in each of the component perspective images are aligned. it is desirable, e.g. to reduce dosage, to convert and intensify the composite image 50 in an image relaying system 49, 55, 56 but this can introduce image distortion (Figure 3 not shown) which reduces the definition of the resultant tomosynthesised image. The improvement comprises using a diaphragm with pinhole aperture located in the object region to form a point image of the radiation source group 43 on the input screen 48 of the image relaying system, and employing the corresponding output point image to correct the image- forming process, for example by correcting the multiple image superposition process. Thus when using an image multiplying point hologram 64, the point hologram can be formed using the output point image. Alternatively a multi-lens projector can be set up using the output point image so that for a selected layer corresponding to the position of the diaphragm, all the point images are made to coincide in the superposition region. In a further alternative of electronic synthesis, the layer dependant shift signals are corrected using the output point image in a similar manner.

Title: Valve for hydraulic shock absorber - has baffles on either side of piston face to allow limited radial liquid flow
IPC: F16F9/348
Filed: 1980-04-17
Abstract: The hydraulic shock absorber has a piston (1) with valves on two faces. These, by their elasticity, press on the ends of channels across the piston body when it moves.
