Title: Adriamycin and adriamycinone
IPC: C07H15/252
Filed: 1969-04-11
Abstract: The antibiotic adriamycin or its aglycone adriamycinone having the Formula I and non-toxic acid-addition salts of adriamycin are prepared by reacting daunomycin or an N- protected derivative thereof or the aglycone with bromine or iodine to convert the 14-CH 3 group to a 14-CH 2 Br or a 14-CH 2 I group and either reacting with alkali metal acetate to give the 14-acetoxy derivative which is then hydrolysed with alkali to the required 14-CH 2 OH group of adriamycin or, in the ease of the 14-CH 2 Br group, hydrolysing this directly with alkali to the 14-CH 2 OH group, then removing the N-protecting gtoup and optionally converting the adriamycin to an acid-addition salt. N-protecting groups may be the trifluoroacetyl group or the Schiff base with salicaldehyde, which are removed by treatment with ethyl chloroformate and p-toluene-sulphonic acid followed by alkaline hydrolysis in the case of the acyl group or acid hydrolysis when the Schiff base is used. The initial halogenation is carried out in an inert solvent, preferably in the presence of CaO when the halogen is iodine, in an inert atmosphere. Pharmaceutical compositions comprise the antibiotic adriamycin or its aglycone, of Formula I above, or a non-toxic acid-addition salt of adriamycin, when prepared by the aforesaid process, together with a pharmaceutical diluent or carrier.

Patent ES-375047-A1 (ES)
Title: Apparatus for kneading doughy explosives
IPC: B01F11/00
Filed: 1969-12-30
Abstract: This apparatus comprises a flexible hose adapted to receive solid and liquid constituents of the explosive. This hose is surrounded by a flexible tube which in turn is surrounded by a rigid tube that is made of a series of sections secured together. Compressed air is supplied into the spaces between the flexible tube and successive sections of the rigid tube successively to force the mixture of the solid and liquid constituents of the explosive down through the hose peristalically. The solid ingredient is supplied to the hose from a hopper through a measuring chamber and rigid tube and the liquid ingredient is supplied from a separate measuring chamber which comprises a flexible cylinder inside a rigid housing. Opposite ends of the cylinder are closed alternately and alternately the outside of the cylinder is put under suction and under pressure. On suction, the liquid component is sucked into the cylinder from a supply source. On pressure the liquid component is forced out of the cylinder into the hose through a nozzle which surrounds the tube that delivers the solid component into the hose. This nozzle directs the liquid against the inside wall of the hose to prevent the solid ingredient from sticking to the hose.

Patent ES-428507-A1 (ES)
Title: Method and machine for rolling threads or the like
IPC: B21H3/00
Filed: 1974-07-13
Abstract: Round blanks consisting of ductile metallic material are formed with threads, knurled or otherwise profiled in a rolling machine wherein a head supports two or more cylindrical dies each having a flat and a profile including a first section of gradually increasing radius, a second section of constant radius and a third section of gradually decreasing radius. The head may rotate about a non-rotating blank so that the dies orbit about the blank, or the blank may rotate about its axis with respect to a stationary head. The flats of the dies face the periphery of the blank when the head is moved to operative position by the slide of a machine tool, and the dies are thereupon caused to turn so as to move the first sections of their profiles into frictional engagement with the blank. The rolling operation is completed when each of the dies completes a single revolution. The rotary movements of dies are synchronized by a gear train whose gears can lock the dies in selected angular positions so that the flats face a blank during movement of the head to or from the operative position. The gears can be unlocked in automatic response to movement of the head to operative position and are relocked as soon as the dies complete a single revolution.

Title: Automatic bed level control for furnaces
IPC: D21C11/12
Filed: 1974-12-10
Abstract: An automatic bed level control system is provided for furnaces which burn a material on a bed, such as chemical recovery furnaces and the like. Optical sensing means sense light emitted by the burning of the bed material and provide a signal which varies as a function of the intensity of the sensed light. The sensing means are structured and oriented to respond to light emanating only from a particular, vertically limited zone in the furnace, such that variations in the intensity of the sensed light are indicative of variations in bed level. The signal provided by the sensing means is then used to regulate some bed level controlling parameter, as for instance primary air flow.

Title: Low temp. aseptic maceration of grapes to make red wine - by inexpensive batch process suited to small scale prodn.
IPC: C12G1/00
Filed: 1978-11-07
Abstract: The installation for treating grapes prior to the fermentation stage, comprises two, thermally insulated vessels of the self-discharging type. The vessels are used alternately for the maceration of successive batches of drained grapes. Maceration includes soaking a batch in preheated wine to achieve a batch temp. of about 50 degrees C., for about 10 minutes. The wine is recycled and the grapes, after maceration, are immediately transferred to a press for extn. of juice to be fermented. Each vessel is pref. fitted with a top cover which is refrigerated to condense and return alcoholic vapours. The cover pref. incorporates an under-pressure relief trap and a restricted vent to atmos. which is cooled to minimise loss of vapour. The relief trap is pref. a counter balanced, hinged, trap door. Wine is pref. circulated through a thermostatically controlled heat exchanger and can be directed automatically via either batch vessel or to a storage tank. The process simultaneously provides a low temp. aseptic treatment which ensures retention of pectolytic enzymes vital to clarification of the prod. The required asepsis is achieved without using, or with very little, sulphur dioxide. The installation is simple and inexpensive to a degree which makes it attractive to small and medium-sized wine producers who could not justify the investment necessary for the continuous plant.

Title: Pulse suppressor for spark erosion machine - has output signal of voltage comparator transmitted to switch via memory
IPC: B23H1/02
Filed: 1979-07-18
Abstract: The pulse suppressor is for spark erosion machines with an electrical pulse generator connected to the main gap. This also has a pulse detector to identify non-effective pulses by controlling a switch to switch off the pulse voltage fed to the gap when necessary. The pulse detector has a voltage compactor which, on passing through a given voltage level, generates a pulse suppressing switch voltage. The output signal of the voltage compactor is transmitted to the switch device by means of a memory fed by the output signal. The memory content is transmitted at intervals to the switch device.
