Patent ES-335036-A1 (ES)
Title: Penicillins and process for preparing them
IPC: C07D499/00
Filed: 1966-12-28
Abstract: The invention relates to a method for preparing thienyloxymethyl penicillins of general Formula I wherein R 1 and R 2 each represent H or CH 3 , and physiologically tolerable salts thereof, disclosed in Specification 1,144,227. Preferred is 3-thienyloxymethyl penicillin and the potassium salt thereof. The penicillins are produced by growing a penicillin-producing fungus, e.g. Penicillium chrysogenum, in a conventional culture medium in the presence of a precursor, which is a thienyloxyacetic acid of formula wherein R 1 and R 2 have the above meaning, or a functional derivative thereof, e.g. a salt, alcohol or aldehyde of said acid. The penicillin and excess precursor are extracted from the clarified fermentation broth at pH 1.5 to 2À5 by a water-immiscible organic solvent such as butyl acetate, transferred into an aqueous buffer at pH 6.0 to 8.5 and re-extracted with butyl acetate at pH 1.5 to 2.5. The penicillin and the precursor are fractionally precipitated from the organic solvent extract by the addition of a solid, or preferably dissolved, salt of an aliphatic carboxylic acid containing 1 to 20 carbon atoms, e.g. palmitic, oleic, stearic, oxalic or malonic acids. The carboxylic acid salt may be inorganic (e.g. alkali metal, alkaline earth metal or ammonium) or organic (e.g. an amine salt). The penicillin is obtained in a pure form and may be converted to any desired salt. A pharmaceutical composition for injection or oral administration comprises thienyloxymethyl penicillin of Formula I, or a physiologically tolerable salt thereof, and a carrier.

Title: Apparatus for the production of thermoplastic mixtures by continuous homogenisation thereof
IPC: B29C48/395
Filed: 1967-03-09
Abstract: In a method of homogenizing a thermoplastics mixture by shearing, the mixture or components are closed at successive points in the treatment zone, the rise in temperature due to treatment being counteracted by a low initial temperature of the next addition.

Title: Electronic proportional and integral controller with limited saturation of the integral action
IPC: G05B11/42
Filed: 1967-03-18
Abstract: In a system in which a variable is controlled by a signal dependent on the. difference and the integral of the difference between the value of the variable and a set value, a further control signal, developed when the first signal is outside predetermined limits, restores the first signal within the limits and persists temporarily thereafter. In Fig. 4, a voltage VM dependent on the magnitude of a process variable is compared with a voltage V c corresponding to a desired value and any difference is effective through an inverter F, amplifier G and converter N to control a regulator (not shown) so as to tend to maintain the variable at the desired value. A voltage V cr dependent on the amplifier output is fed back to the amplifier through a resistance-capacity network AP, AI (not shown in detail) so that the control system has an adjustable proportional-integral characteristic. To prevent overloading of the integrator during large disturbances, portions of the feedback voltage are also applied through resistancecapacity delay networks Ph, Ch and Pb, Cb to transistor amplifiers Gh, Gb which are respectively operated by signals above and below predetermined amplifier threshold values to produce voltages across a resistor R which buck or boost the input to amplifier G as necessary to counter the effect of the disturbance.

Title: A Process for Treating Polyolefine Material.
IPC: B29C71/04
Filed: 1967-04-26
Abstract: A retractile polyolefin wrapping material is made by initially stretching the material fully to the extent required for use for wrapping so as to impart orientation thereto and then subjecting the material to an ionising radiation such that the material receives an irradiation dosage of 1 to 5 megarads, preferably 1À5 to 3À5 megarads. The preferred polyolefin material is polyethylene. Articles may be wrapped in sheets of the polyolefin material so produced and the material heated to a temperature of 120 to 145 C. to release the pre-stresses therein and so cause the material to contract on to the article. In a preferred wrapping method, the article is wrapped in a sheet of wrapping material of the required size, and the edges of the sheet heat-sealed by bringing them together and welding them by the application of a heated member or wire. This can be adapted to produce the weld and to cut the edges of the sheet simultaneously. Sealing may also be carried out by any other known method used for the hot-welding of plastics, such as high-frequency hot welding. When the seal has been made, the wrapped article is placed into a device in which the wrapping material is heated to a temperature of 120 to 145 C., which relieves the internal stresses and causes the wrapping material to contract and tighten on to the article.

Title: Associative Memory
IPC: G11C15/04
Filed: 1968-10-03
Abstract: In an associative memory, each word store has a plurality of bi-stable devices associated with it, setting of any one of which enables a read or write signal subsequently to be applied to the word store, selection means being provided to set a selectable one of the bi-stable devices in response to the generation of a match signal. The associative store of Fig. 1 comprises: an input register 2 a mask register (with gates) 4 logic circuits 6 word stores 7 each bit position being capable of three states viz. 0, 1, nothing a primary and a secondary trigger 16, 17 respectively (with logic) associated with each word store an output register 9 and a decoder 19 which can produce any of the following operations: SELECT: those orders of the input register 2 which correspond to orders of the mask register 4 set at 1 are compared with corresponding orders of the word stores 7 (decoder output S energized), match setting either the primary or the secondary trigger (according as decoder output P or SY is energized). SELECT NEXT: like " select " only the primary or secondary trigger of the next word store is set on match, not that of the word store giving the match (decoder output N also energized). TRANSFER TO NEXT: the set state of each set primary or secondary trigger (depending on whether P or SY is energized) is transferred to the next such trigger (N energized). READ: those word stores whose primary or secondary triggers (depending on P or SY) are set are read out to the output register 9 simultaneously (so that if there are a plurality of such word stores corresponding bits are ORed on the column lines 11, 12) and in any event only those positions at which the mask register 4 holds 0 are gated at 71 to the output register 9 (decoder output R energized). WRITE: contents of input register 2 at those orders corresponding to orders of the mask register 4 set at 0 are written into those word stores having the primary or secondary trigger set (depending on P or SY W also energized). SET MASK: input register 2 loads the mask register 4 (SM energized). SWITCH: output SW of decoder 19 is energized to overrule the selective effects of the mask register 4. Combinations of the above operations are possible. In a computer, accessing of instruction words belonging to the main programme and to subroutines may be controlled by the primary and secondary triggers respectively TRANSFER TO NEXT followed by READ can be used for stepping through a set of consecutive instructions, a branch being initiated by using SWITCH as well.

Title: Iris diaphragm
IPC: G03B9/00
Filed: 1973-05-18
Abstract: An iris diaphragm includes shutter blades moved by a conventional control member during a first phase of adjustment to reduce the aperture to a size at which diffraction effects are still unimportant. In a second phase of adjustment the shutter blades are stationary and a transparent support member is moved to introduce increasingly dense portions of a graduated filter into the optical path. Light control over a range of 1:1,000,000 may thus be obtained. There may follow a third phase in which the shutter blades again move to reduce the aperture to zero. The blades and the filter support may be placed on opposite sides of a permanent stop and actuated by respective control members coupled to a common setting ring. Alternatively the blades and filter support may be on the same side of the stop and actuated by a common control member. The filter support may be introduced into the optical path only after the first phase has ended, or a transparent portion thereof may be always in the optical path, the filter-carrying portion being brought into action only during the second phase.
