Title: Pneumatic take-up or tensioning device for circular knitting machines
IPC: D04B15/92
Filed: 1964-06-19
Abstract: A pneumatic tensioning device for a circular knitting machine comprises means to produce an airflow in an upward direction which pulls the tubular knitted fabric directly into an external tube 18, without allowing the fabric to enter the needle cylinder, the external tube 18 being arranged eccentrically with respect to the axis of the needle cylinder. In Fig. 3 the airflow is created by a fan 23 and a tube 19 mounted within the needle cylinder. In a modification Fig. 5 (not shown) the airflow is produced by connecting the tube 18 directly to an external source of suction or low pressure, a trap being provided to remove the articles produced from the intermediate piping before reacting the suction fan.
Patent ES-337894-A1 (ES)
Title: Locking system for a card reader
IPC: G06K7/06
Filed: 1967-03-11
Abstract: A handle (not shown) which is manually operable to lower an array of spring contacts on to a card 1, and which is fixed to shaft 24, is locked with the array in the inoperative position by a pawl 42 until a card 1 has been correctly inserted so that its leading edge releases cam 44 by way of lever 35, bell-crank 40 and pawl 42. In the fully inserted position the card is pressed against a shoulder by the action of spring 38 and lever 37. When the handle is raised, the carriage carrying the spring contact array rises off the card 1 by spring action and lugs beneath the carriage lift card 1 free of the shoulder so that it is ejected by spring 38 and the locking mechanism again becomes operative.
Patent ES-340798-A1 (ES)
Title: Control circuit for multistage crosspoint network
IPC: H04Q3/00
Filed: 1967-05-20
Abstract: In a multistage relay switching network having a plurality of crosspoint matrices per stage, each matrix has associated therewith a marking relay whose contacts are connected in series with all the energizing coils of the relays in that matrix. During route finding, one matrix in each stage is selected and the corresponding marking relays are operated and thereafter operating potentials are applied to the relevant network inlet and outlet (the latter having been chosen from a plurality of possible outlets if necessary) whereby those crosspoint relays in the single path between the inlet and outlet come up and hold via their own contacts. The network trunking is such that each matrix in one stage has access to each of the matrices in the succeeding stages via one link only. Particular description.-Fig. 2 depicts an m x n matrix having a relay KP at each crosspoint. In all stages except the first, each matrix has an associated marking relay H and each column of a matrix has an individual busying relay Z. The crosspoint relays of a column are each connected via a decoupling diode Gl in series with a contact h, e.g. h1 in column C1, of the matrices' marking relay. As can be more clearly seen in Fig. 3, completion of the path search operation results in the h contacts in the chosen matrices being operated whereby, when potentials + U and - U1 are applied to the ends of the network, one KP relay is brought up in each stage. The H relays are released whereupon the two column busying relays Z come up and the path is then held by means of earth in the feedbridge VS1 and - U2 in the line circuit TS1. In order to prevent undue current surges through the Z relays, the by-paths e.g. Ql, h, z around these relays may include resistors so that as soon as a KP operates a low current starts to flow through its Z relay (Fig. 4, not shown).

Title: High density sodium tripolyphosphate (form 1)
IPC: C01B25/41
Filed: 1967-06-23
Abstract: Sodium tripolyphosphates which differ in size and density having a size of substantially -20 + 100 mesh and bulk density between 0À95 and 1À3 g/cc. are prepared by feeding aqueous sodium orthophosphate having an Na/P molar ratio of 1À63 to 1À7 into afluidized bed comprising discrete particles of sodium tripolyphosphate at a temperature of 220-400 C. A portion of the particles are removed and separated into a coarse and a fine fraction. The coarse fraction is crushed, and optionally mixed with a portion of the fine fraction, to produce a mixture of average size smaller than that of the bed. This crushed mixture is recycled to the bed. The remaining fine fraction may be recovered as product Form II sodium tripolyphosphate or may be transferred to a second fluidized bed and maintained at 425-550 C. Sodium tripolyphosphate particles are removed from this second bed having a higher Form I content than the particles introduced. The crushed particles, in the first stage, are advantageously subjected to high-speed mechanical attrition before being recycled to the first bed.

Title: Feeding apparatus for pulverulent or granular material
IPC: B65G65/00
Filed: 1969-04-07
Abstract: An apparatus for feeding fluidized pulverulent or granular material at a substantially constant rate to a hopper 30, comprises an inclined band conveyer 6 having an upwardly moving conveying run to which an overlying cover 11 is sealed, forming a closed duct having a lower inlet 28 and an upper outlet 14, and means for maintaining the height of material in a shaft 18 connected to the inlet 28 substantially equal to the height between the duct inlet and outlet, so that a substantially constant pressure head of material in the shaft 18 is applied to the material moving along the closed duct. The material having been previously aerated, is fed to the shaft 18 by a worm conveyer 23 and is maintained at the said height by adjustable overflow plates 25 adjacent outlets from the shaft 18, the outlets being in communication with a reservoir for the material. The shaft 18 is coupled by a flexible seal 20 to a collar 15 extending from the cover 11, and the collar may include nozzles for injecting fluidizing air into the material if the initial aeration is insufficient. The conveyer. 6 and its frame 1 are balanced in an inclined position on knife edges 2 and any tendencyfor the frame to tilt due to variation in the density of material on the conveyer 6 is registered by a load cell 33 which controls the conveyer drive motor such that a constant rateby weight of material is delivered to the hopper 30. In the embodiment of Fig. 4 (not shown), the material flowing over the level control plates is caught in a gutter where it is fluidized for subsequent discharge therefrom. In the embodiment of Fig. 5 (not shown), the material'level in the supply shaft is maintained by a pressure sensitive device therein which controls the screw conveyer supplying the material. In the final embodiment of Fig. 6 (not shown), the screw conveyer is replaced by valve controlled gravity feed system, the valve being actuated by a pressure sensitive device as in the last said embodiment.

Title: Latch opener apparatus for knitting machines and particularly circular knitting machines
IPC: D04B15/08
Filed: 1972-06-17
Abstract: A tubular housing retains a spirally wound torsion spring, which is locked in one position and bears against a rotatable carrier which carries the latch opener itself in the form of a hook having a first bend, the inside corner of which may be formed as a cutting edge and a second bend at an obtuse angle engaging the latches of the needle. If a needle latch should not open, or the needle be bent, the latch opener swings against the force of the torsion spring, thus tripping a shut-off switch to stop the machine, and simultaneously giving an indication by an indicator lamp which latch opener has tripped.

Patent ES-431498-A1 (ES)
Title: Holder for tools and similar objects
IPC: B25D17/08
Filed: 1974-10-30
Abstract: A tube has an open end and an outer circumference and is formed with a transverse incision which extends inwardly towards the axis and is inclined longitudinally of the tube towards the open end of the latter. A sleeve surrounds the tube with clearance and is formed in its inner circumference with a substantially radial slot. A cylindrical locking member extends normal to the axis of the tube through the incision, being freely slidable therein, and has end portions projecting beyond the tube into the slot. A biasing spring normally biases the sleeve to a position relative to the tube in which the locking member is prevented from sliding in the incision because of the fact that its end portions are received in the slot of the sleeve, until the sleeve is displaced axially of the tube against the force of the biasing spring to a position in which the locking member can freely slide in the incision.
