Patent ES-346823-A1 (ES)
Title: Electronic musical instrument provided with generators and individual formant filters
IPC: G10H1/12
Filed: 1967-11-06
Abstract: An electronic musical instrument comprises tone generators having associated individual formant fitters and a plurality of keys connecting outputs from selected fitters to the instrument output, the keying operation shifting the Q factors of corresponding fitters between two stable values to vary the timbre of the instrument output. The formants may be parallel or series resonant circuits (Figs. 1, 2, not shown), having resistors whose values are changed on depression of a key to change the Q factors. The resistors may be replaced by photo-cells or transistors. The formant fitters may be included in the generator circuits and arranged to control the output frequencies of the generators (Figs. 3, 4, not shown). Each fitter may have a plurality of resonant frequencies, one to determine the ultimate pitch of the generator, and others to determine the ultimate formant. The ratio of the resonant frequencies may be 1 : 2 for simulating open organ pipe tones, or 1 : 3 for simulating stopped pipes, or may be non-integral for imitating reed pipes (Fig. 5, not shown).

Title: Process of producing rolled stock from a high-melting metal by continuous casting and rolling operations
IPC: B21B1/46
Filed: 1967-11-30
Abstract: Rolls 5 which shape and reduce the crosssection of a cast strand 4, e.g. of carbon or alloy steel, are disposed at a location where the molten core thickness would be 5-30 mm., without the rolls, to reduce the core length so that the core tip closely precedes the plane in which the strand assumes its rolled shape, the casting conditions being adjusted, according to the cross-sectional areas and velocities of the strand (determined by sensing units 1, 2) upstream and downstream of the rolls 5, to obtain at the location a desired theoretical proportion of core in the strand cross-section, which proportion would exist if the rolls were absent. The core size is adjusted by altering the strand withdrawal or cooling rate. There may be extra shaping rolls 6-8.

Patent ES-368441-A1 (ES)
Title: Log chipping apparatus
IPC: B27L11/00
Filed: 1969-06-17
Abstract: Log chipping apparatus includes means for feeding a log 40 towards movable chipping means at a chipping station 1, stop means, means for moving the stop means from a first position to a second position in the path of the log for engagement with the log to interrupt its movement toward the station 1, and operating means which are responsive to changes in the rate of movement of the chipping means for moving the stop means between its two positions. The arrangement is such that the stop means interrupt feed of the log when the speed of the chipping means falls below a certain value. In the apparatus shown the log 40 is fed by a conveyer 15 to a chipping disc 5 which includes cutting blades 8 and fan blades 9. The blades 9 direct the cut chips into a shoot 50. The disc 5 is driven from the shaft 17 of an engine 16, and a tachometer monitors the speed of shaft 17. When the shaft speed falls below a predetermined value, the tachometer causes a switch to be closed which actuates a relay. The relay operates the control valves of an hydraulic cylinder 28 so that the piston-rod 31 thereof is extended and pivots an arm 22 so that a blade 26 carried by the arm engages the log 40 to hold it in position. The blade 26 constitutes the stop means. The relay also de-energizes an hydraulic motor for the conveyer 15 so that feed of the log is halted. When the shaft speed again increases the switch and relay are again operated to lift blade 26 and re-start conveyer 15.
Patent ES-370433-A1 (ES)
Title: Oleandomycin fermentation recovery
IPC: C07H17/08
Filed: 1969-08-12
Abstract: In a process for recovering oleandomycin from a fermentation broth obtained by cultivating an oleandomycin-producing micro-organism, the pH of the fresh broth is brought to 5 to 6 with mineral acid and maintained thereat for at least two hours, the oleandomycin then being recovered by a conventional procedure. A suitable micro-organism is Streptomyces antibioticus. The fresh broth, initially having a pH of about 6.5 or above, may be acidified before or after removal of the mycelium, suitable mineral acids being sulphuric, hydrochloric, hydrobromic or phosphoric acid. Oleandomycin is isolated by e.g. removal of the mycelium, making the filtrate slightly alkaline, extracting the antibiotic into methyl isobutyl ketone and shaking the extract with 50% aqueous H 2 SO 4 the aqueous phase is separated, made slightly alkaline, and the antibiotic extracted into CHCl 3 which is distilled off to leave the required product. The mineral acid treatment at pH 5 to 6 is said to promote the enzymatic conversion of antibiotically inactive oleandomycin-X present in the fermentation broth, to oleandomycin, giving an improved yields of the latter.

Title: Flow-control arrangements in axial-cylinder pumps
IPC: F04B1/20
Filed: 1972-11-10
Abstract: A fluid-tight seal between each cylinder bore in the barrel of a swash-plate pump and the corresponding port bore in a port plate rotating with the barrel is established by a sleeve, which is accommodated in aligned counterbores of the two bores, provided at the mutually adjacent end faces of the barrel and port plate, and which is sealed in each of these counter bores by a separate compressed O-ring seal, common rotation of the port plate with the barrel being ensured by means independent of the sleeves.

Abstract: A method and apparatus for disinfecting rooms and articles in the rooms. The apparatus comprises a housing having an interior disinfecting chamber which is connected through a valve to a scavenging chamber containing a scavenging fan, which has a discharge to atmosphere. An inlet chamber has an inlet valve which may be opened for the inflow of air through a filter into the inlet chamber and the disinfectant chamber. In addition, the housing contains a circulating fan chamber which is connected through an inlet passage having a plurality of circulating socket connections which extend from the circulating fan passage into the disinfectant chamber, and which may be advantageously connected selectively to articles which are to be disinfected. The discharge passage for the circulating fan which extends from the circulating fan passage into the disinfecting passage, passes over preferably at least one evaporator for the evaporation of the disinfectant and, preferably, two evaporators, one of which is an evaporator for a neutralizing agent for the disinfectant. In the method, disinfectant is added to the air in the disinfectant chamber to form a disinfectant gas which may advantageously be evaporated or atomized in the presence of air which is circulated into the chamber. The disinfectant gas is heated and circulated to disinfect the chamber and the articles therein and, thereafter, the disinfectant gas is exhausted from the chamber and air is circulated through the chamber to scavenge it. In a subsequent operation, the air in the chamber is heated in order to evaporate the residual disinfectant and after expiration of a predetermined period of time, this heated air is scavenged from the chamber by circulating fresh air therethrough.
