Title: Improvements in or relating to pressing filters
IPC: B01D33/04
Filed: 1969-02-15
Abstract: In the type of extraction apparatus wherein a filter web 23 travels through a compression zone 11 of progressively decreasing width defined by a pair of rotary members 1, at least one member 1 comprises an endless conveyor of hinged plate-like elements 8 whose lengths are at least equal to the separations between backing pressure rollers 19. This arrangement is stated to produce a more uniform pressure distribution. As described, filter web 23 is endless and is suspended from chains 24. Throughout most of its path it is relatively flat, but it is caused to adopt a U-section shape, Fig. 3, when passing through the compression zone 11 between the converging conveyor members. The open top of the U-section web 23 may be closed off during compression, to define (in effect) a tube (Figs. 13, not shown). Fruit pulp is introduced at 22 and expressed and filtered juice is caught by trough 31. Plate members 8 may be imperforate or formed from intercolated bars (Fig. 7, not shown). Rollers 19 are resiliently loaded. In other embodiments: (i) web 23 is replaced by three similar parallel webs, (Fig. 12, not shown) (ii) the conveyor runs are horizontal, web 23 being replaced by two endless non-profiled webs (50, 51, Fig. 14, not shown) (iii) one conveyor is replaced by a drum (35) which rotates inside the other conveyor (ii), a pair of filter webs (38, 39) moving in the compression zone so defined between them (Figs. 15, 16, not shown). Other features. The pulp may be preliminarily squeezed in the filter web by an array of rollers (53) before entering input zone 22, Figs. 8, 9 (not shown). Roller adjusting means, and means for scraping, brushing, beating and washing the filter web, are disclosed.

Patent ES-368051-A1 (ES)
Title: Symmetrical polyphase networks utilizing constant reactances
IPC: H03H11/22
Filed: 1969-06-04
Abstract: A symmetrical polyphase network includes, in each phase, a frequency invarient reactance such that the network responds differently to input signals of negative and positive frequency. Such networks may be employed in N-path commutated circuits or as single sideband modulators. In one embodiment, Fig. 8 (not shown), comprising a two-phase network, the frequency invarient reactances are formed by two port gyrators (G3 . . . G6) having one port connected to each phase. In an alternative form, Fig. 14, the reactances are constituted by fourport networks which transform resistances into reactances (l: j transformers) 1 . . . 4. The circuit may also include negative impedance converters, Fig. 15 (not shown), to change the sign of the reactances. If the capacitors of Fig. 14 are omitted, the circuit of Fig. 14 non- stitutes an N-port gyrator. One form of i:j transformer suitable for a two-phase system, Fig. 9B, is a voltage shift type in which each phase includes a series transistor VT1, VT2, with the collectors of each transistor being connected to the base of the other, one connection being via a third transistor VT3. If impedances Z are connected across each output, impedances jZ will be seen looking into each input. The input and output connections may be reversed, Fig. 10B (not shown). The circuit may also be modified for current shift operation by connecting the input or output terminals to the bases of the series transistors, Figs. 11B, 12B (not shown). For three-phase networks, Fig. 22, 1: h transformers 11A . . . 11D are used, in which h represents a 2#/3 phase shift. Suitable transformer circuits comprise a series transistor in each phase, each having its base electrode connected to the collector of the transistor in an adjacent phase either directly, Figs. 16, 17 (not shown) or via emitter followers, Figs. 18, 20 (not shown). For four-phase operation l:j transformers may be employed which are similar in form to the l: h transformer of the three-phase system, Figs. 25, 26 (not shown). By suitably connecting the four outputs the circuits may be arranged to operate in a voltage or a current shift mode, and may transform by j. A two-phase circuit which attenuates frequencies of one polarity and passes those of the other may be used as a quadrature modulator, Fig. 32. If an input carrier signal V is applied to one input port V 1 , and the other input port V 2 is earthed, then quadrature carriers are obtained at the two output ports V 3 , V 4 . These are then modulated with quadrature modulation signals in 7, 8 and the two modulated signals added to produce a single sideband output.

Title: Method and means for controlling the sex of mammalian offspring and product therefor
IPC: A01K67/02
Filed: 1970-04-09
Abstract: A method of controlling the sex of mammalian offspring by separating spermatozoa into fractions having the desired sex characteristics and artificially inseminating the female to produce offspring of the desired sex. The sperm is separated by applying a buoyant force or forces to a mixture of sperm in nutrient media so that separation occurs according to density of the sperm. The nutrient media is controlled as to density characteristics and can have a uniform density gradient from top to bottom so that buoyant forces within such media are selectively applied to sperm of differing density to effect separation of the sperm and to hold sperm fractions of different density in suspended relation within the nutrient media. Substantially pure sperm fractions (having the desired male or female sex characteristics) are isolated at the top or at the bottom of a separation column for use in artificially inseminating the female. Under certain circumstances, separation of the sperm into fractions is enhanced by the application of gas pressure (positive or negative) above the mixture of sperm and nutrient media in the column.

Title: Method of reinforcing rock strata
IPC: E21D21/00
Filed: 1976-04-01
Abstract: A method of reinforcing rock strata, such as that around underground openings in mines, is effected by using a first wooden reinforcing dowel to drive a second wooden reinforcing dowel into contact with resin capsules located at the inner end of a borehole. The first dowel is then removed from the borehole while additional resin capsules are positioned in the borehole and a further wooden dowel is then inserted into the borehole so as to become embedded in mixed resinous composition from the additional capsules. In this manner it is possible to reinforce the strata to a considerable depth, for example upwards of 16 feet, without the danger of metallic drill rods becoming jammed in the borehole and thereby obstructing subsequent cutting of the reinforced strata by mining machinery.

Patent ES-463967-A1 (ES)
Title: Cement mixture blowing device
IPC: B65G53/46
Filed: 1977-11-08
Abstract: A cement mixture is mixed or agitated in a hopper by rotary blades and is fed through a feed duct or chute normally imparted with vibrations from a vibrator to cement mixture receiving pockets in a rotary disk. The cement mixture in the pocket brought to an unloading position is forced to be discharged through a discharge pipe under the force of the air under pressure admitted into the pocket through a blow pipe. Since the feed duct or chute is normally vibrated, even a highly viscous cement mixture containing water can be fed through the feed duct or chute into the pockets of the rotary disk in a stable manner so that the cement mixture may be prevented from bridging across the pockets of the rotary disk, thereby not dropping into them.
