Patent ES-389517-A1 (ES)
Title: Coder-decoder for use in a delta-transmission system
IPC: H03M3/02
Filed: 1971-03-24
Abstract: A delta modulation transmitter includes comparator means to produce a comparison signal derived from a comparison circuit for an input analog signal and a pulse code modulator and features an AC coupled feedback from another output signal of the pulse code modulator. The AC coupled feedback signal is superimposed onto the difference signal produced by the comparator thereby to provide a reliable output signal from the pulse code modulator for a zero input analog signal and in addition, to suppress noise which would otherwise be produced in a cooperating receiver.

Title: Patterning mechanism for multi-feed circular knitting machines
IPC: D04B15/78
Filed: 1973-03-10
Abstract: Pattern jacks in a multi-feed circular knitting machine are accommodated in a cylinder co-axial with but of a larger diameter than the needle cylinder. Jack butts are set out in diagonal lines. At each feed there is a slotted block housing a vertical bank of superimposed pairs of jack selector tuck and knit slides having cam faces upwardly sloping to two different extents heightwise. Springs urge selector slides into operative positions, slides being selectively held withdrawn clear of jack butts against the biassing influence. Movements of jacks imparted by slides are less than sufficient to raise corresponding needles to heights required. Thus movement transmitting and amplifying levers are provided between the jacks and the needles.

Title: Proteinaceous food product
IPC: A23L13/60
Filed: 1974-10-18
Abstract: A novel, protein-rich food product, especially suitable for domestic animals, is made by subjecting protein material such as meats or fish to acid-producing fermentation, and preferably also to autolysis or proteolysis, and adding the acidic fermented material to a colloidal solution of protein, such as milk or soya milk, whereupon the diposed protein is precipitated and forms a curd that entraps and binds the particles of fermented material. The curd and entrapped material are separated off and compacted into a coherent mass. The product, which is a compacted mass of the precipitated protein with particles of the fermented material distributed through it, can have the consistency of a cheese and may be formed into "cheese" shapes. The flavor of the product is influenced by the nature of the fermented material.

Title: Drying solvent-contg. prods. in a hot gas stream - and condensing the solvent in an exchanger using the same liq. gas as coolant
IPC: F26B21/08
Filed: 1977-04-15
Abstract: Method comprises recycling a convection gas is recycled over the solvent-contg. material in a cycle comprising a drying chamber and an exchanger-cooler with a liq. refrigerant where the solvent is substantially condensed. The liq. refrigerant is of the same nature as the convection gas and at least part of the cooling fluid, in the reheated gaseous state, is mixed with the said convection gas at a point in the cycle beyond the outlet from the solvent condensn. zone. The solvent used condenses at a much lower temp. than water and may be e.g. acetone, ethyl acetate, ethanol, methylene chloride, hexane, pentane, THF, toluene, etc. The convection gas/cooling liq. may be N2 or CO2. Drying is accomplished in a relatively simple appts. which is economical in operation. Drying is carried out with a gas which is inert towards the solvent, and fire risks are reduced by the exclusion of air from the system.

Title: Process for the preparation of thiochroman derivatives
IPC: C07D335/06
Filed: 1977-08-19
Abstract: A side chain -OCH2CHOHCH2NHR2 is fixed to a hydroxythiochroman of formula: < IMAGE > by a 2-stage synthesis, a) reaction with a glycerol halohydrin in basic medium and b) reaction of the 2,3-dihydroxypropoxythiochroman thus formed with an amine R2NH2 in the presence of an aminotriphenylphosphonium halide. The compounds (I) thus obtained and their salts are known as beta -blocking agents and used, especially, in the treatment of disorders of the cardiac rhythm. Compared with the prior process starting from the same compounds (II) and ending in the same compounds (I), the new process requires shorter reaction times and a reduced quantity of the amine R2NH2, which makes possible a selective amination of the primary alcohol functional group.
Patent ES-461862-A1 (ES)
Title: Selective duplicating machine
IPC: B41L47/58
Filed: 1977-08-24
Abstract: A duplicating machine for duplicating printed material from selected master cards onto a workpiece comprises a master card feed station including a feed device for feeding cards to a print station and a workpiece feed station including a device for feeding workpieces to a moistening apparatus and to the print station. Also provided is a card reading device for detecting predetermined information characteristics stored on an adjacent master card in a stack and for determining whether the printed material on that card is to be duplicated. If the material is to be duplicated the reading device provides a signal to a control system that actuates the workpiece feed device for feeding the workpiece to the print station. As the workpiece is fed from its feed station, it actuates an envelope feed detector which provides a signal that operates a common drive arrangement that actuates the moistening apparatus and the master card feed device whereby the master card and a moistened workpiece arrive at the print station for duplicating the printed material from the master card onto the workpiece. If the printed material on the card being read is not to be duplicated, the reading device provides another signal that operates the common drive arrangement so that only the master card is fed to the print station whereby the printed material is not duplicated.

Title: Windscreen wiper motor control circuit
IPC: B60S1/48
Filed: 1978-12-19
Abstract: A windscreen wiper motor 10 with a parking switch 14 is controlled by a control switch 20 to operate in a first normal mode via a first current supply circuit 11, 21, 13 and a second intermittent mode via a switching element 33, 34 independent of the switch 21 in a second current supply circuit 31, 30, the motor always being parked through the second current supply circuit 30 regardless of the mode of operation, so that the parking position of the wipers is independent of the mode of operation. To park the wipers, switch 20 is moved to position O from continuous-operation position II or III or intermittent-operation position I, whereby second supply circuit 30 energises the motor (via 22, 32, 36, 38) until parking contacts 15, 16 close to cause 33, 34 to switch off and complete a motor short-circuit braking path (via 15, 16, 37, 38, 32, 22, 11). Such operation occurs on switch movement from or through position I. Alternatively energisation of circuit 30 in position O may be employed using the motor back EMF as a control signal, Figures 2 to 4 (not shown), the Figure 4 modification ensuring that (1) operation is reliable at low values of back EMF and (2) the parking position is unaltered when ignition switch (92) is opened, since the battery is connected directly to circuit 30 and through switch (92) to switch 20.
