Patent ES-361663-A1 (ES)
Title: Sheet conveying,stacking and discharge equipment
IPC: B65H33/12
Filed: 1968-12-19
Abstract: Corrugated sheets cut from a strip are fed by a belt 25, Fig. 1, in overlapped relationship beneath retaining rollers 59, below a gate 15 on to a stacking unit comprising a first frame 181, Fig. 2, carrying a plurality of longitudinal rotatable rollers 186, and a second frame 198 carrying a plurality of slats 233. The slats are normally well above the rollers, the frame 198 being vertically movable by pneumatic actuators 197. The sheets are received by the slats which move downwards in steps as the stack grows. When a photo-cell 352 registers a given number of sheets, the gate is lowered to cut off the supply to the stack, and the frame 198 is lowered until the slats are just above the rollers, whereupon pneumatic actuators 227 move the slats to the right away from the gate and just below the rollers, which are then rotated to move the stack on to a stack-receiving table, actuating a photo-electric cell 356 to restore the mechanism and raise the gate. Slidably supported on the frame 198 is an assembly 234 including a plate 234 which is reciprocated by an eccentric 251 to jog and align the front of the stack, while a pneumatic actuator 249 moves the plate clear of the stack before the stack is moved.

Title: Closure cap with molded threads
IPC: B65D41/04
Filed: 1969-01-09
Abstract: A method of making a closure cap comprises the steps of positioning a form-retaining ring 6a of a measured quantity of fluxed and mouldable plastisol adjacent the skirt of the cap, and thereafter applying a die to mould screw-threads in the plastisol. The ring may be injected into the cap as a paste at room temperature and subsequently heat cured and moulded. A coating of organosol on the shell 2 together with a primer lacquer acts as a bond between the shell 2 and the ring 6a. A preferred method of forming the threads comprises heating the ring to 400 F. and applying a die at room temperature. Alternatively, if the ring is pre-cut, e.g. of polyvinyl chloride, it may be moulded using a heated die.
Patent ES-396620-A1 (ES)
Title: Dough divider
IPC: A21C5/02
Filed: 1971-11-03
Abstract: Couples or connecting rods involved in the crank drive for the chamber, plunger and slide components are 1.5 times as long as the radius of the crank. - This shortens the rod ratio and produces distortion sufficient to accelerate the movements of the components specified. - All these movements are powered off a single throw of the shaft thus ensuring sufficiently long standstill of the cut-off knife in the closed position and thus keeping the feed chamber divorced from the funnel. - The metered dough has time to pass on via the plunger into the chamber.

Patent ES-443849-A1 (ES)
Title: Time base corrector
IPC: H04N5/956
Filed: 1975-12-24
Abstract: Time base errors, such as are introduced in video or other information signals by the recording and/or reproducing thereof, are removed by writing successive line or other intervals of the video signals in a memory at a clocking rate which varies generally in accordance with the time base errors, and by reading out the video signals from the memory at a standard clocking rate. The memory is composed of at least three registers having repeating cyclic orders or sequences of writing and reading, respectively, and the video signals being read out of each register are recycled or rewritten in the same register. The reading and writing operations are controlled so that the occurrence of excessive time base errors causes the writing or reading period of a register to be extended, for example, from a normal one line interval to two line intervals, so as to either omit or repeat, respectively, a line interval of the video signals in the output from the time base corrector. Further, in response to a detected drop out in the incoming video signals, the writing period of a register is extended so as to omit or delete the line interval containing the drop out from the temporarily stored video signals and, during reading out of the stored signals, the line interval preceding the deleted line interval is read twice to replace the omitted line interval.
Patent ES-445392-A1 (ES)
Title: Method of and apparatus for the dissolution of gases in liquids
IPC: C02F3/26
Filed: 1976-02-20
Abstract: Liquids, e.g. sewage sludge, waste water or oxygen-poor natural water, are treated with gas for enrichment (especially oxygenation) by forcing the liquid downwardly through a perforated wall in a vessel containing the liquid. The perforated partition subdivides the liquid forced downwardly through the column into a plurality of partial streams which open into a gas space above the downwardly moving column of liquid in the melt. Bubbles of the gas, e.g. oxygen, pass upwardly through the column of liquid in the shaft.
Patent ES-450493-A1 (ES)
Title: Stone detector
IPC: G01N21/90
Filed: 1976-08-05
Abstract: An improved device for detection of stones in the sidewalls of glass containers. Stones in the sidewalls of glass containers cause stress patterns to be formed. These patterns are visible if the glass container is viewed through crossed polarizing filters due to the refraction of polarized light. A television camera and electronic analysis circuit may be substituted for the human eye. The detection capability and reliability of the system is improved if the glass container is illuminated with primarily infra-red radiation. Then, polarizing filters which polarize infra-red radiation and remove visible light are used. A filter before the television camera lens removes far infra-red radiation and allows only near infra-red radiation to be measured. This makes the device insensitive to glass color, flutes or stippling and improves the signal to noise ratio.
Patent ES-452709-A1 (ES)
Title: Making a pelletized glass batch for soda-lime glass manufacture
IPC: C03B1/02
Filed: 1976-10-26
Abstract: This invention pertains to improvements in the manufacture of soda-lime glass from pelletized glass batch material in which a major portion of the alkali metal oxide flux material (e.g. Na2O) in the final glass is derived from an alkali metal hydroxide (e.g. NaOH) and in which the alkali metal hydroxide is reacted with alkaline earth metal oxide source material during the preparation of the pelletized glass batch material. The improvements are obtained by reacting aqueous, concentrated, alkali metal hydroxide with at least a portion of the alkaline earth metal oxide source material (e.g. limestone) to form an aqueous slurry which contains the reaction products, then mixing with the slurry the remaining glass batch materials under conditions to assure thorough mixing and then pelletizing and heating the batch material at a temperature of at least about 145 DEG C to assure substantially complete drying of the pellets and substantially complete reaction of the alkali metal hydroxide.

Finely divided carrier material, such as calcium carbonate, is then added to the extent of 50 to 100 weight percent based on the dry matter, and the mixture is agitated to get a uniform mix. The uniform mixture is then spray dried to produce substantially spherical particles of the zinc bacitracin composition.
Patent ES-464209-A1 (ES)
Title: Train indicator system using axle detectors - has auxiliary circuit to correct false indication due to count errors
IPC: B61L1/16
Filed: 1977-11-16
Abstract: A track indicator circuit for railways has an axle detector at a counting station (ZP1-ZP5) at the start of each track section (GA1-GA4). Coupled between successive detectors is a series of up-down counters (AZ1-AZ4) connected so that pulses from the axle detector at the start of a section of track triggers the respective counter in the forward direction whilst the succeeding detector triggers it in the reverse direction. Ideally, when a train has passed completely through a track section, the corresponding counter will have returned to zero and will give a "track clear" indication. Count errors are corrected by means of an auxiliary circuit (ZS1) which compares the count tally for a section with that of succeeding sections.

Patent ES-476969-A1 (ES)
Title: Chroma demodulator circuit for SECAM television signals.
IPC: H03G11/06
Filed: 1979-01-18
Abstract: A known form of SECAM subcarrier demodulator employs a multi-stage limiter-amplifier (15) to supply two inputs (L, P) to a signal multiplier (19), one input (L) being supplied directly and the other input (P) being supplied via a phase shifter (17) which imparts a phase shift of 90 DEG C at one of the SECAM subcarrier resting frequencies. One of the amplifier stages, preferably the final amplifier stage (15C), of the limiter-amplifier (15) is provided according to the invention, such as by the provision of positive feedback (via 68), with a hysteresis characteristic ensuring development of a limiter output having a rectangular waveshape with rise and fall times of substantial constancy, independent of input signal amplitude variations. Negative DC feedback (through 71) from the penultimate amplifier stage (15B) to the input amplifier stage (15A) of the limiter-amplifier (15) can also be provided to assure desired symmetry of limiting action. Color difference signal output is obtained by low pass filtering (21) of the products of multiplication of the respective signal inputs.
