Patent ES-346462-A1 (ES)
Title: Improvements in and relating to closure members for containers
IPC: B65B7/28
Filed: 1967-10-26
Abstract: A plastics cover is sealed to a container mouth by plasticizing it, bringing the mouth into contact with it and then using vacuum to draw cover material extending beyond the mouth against the container neck or rim. In one embodiment, the container 10 is placed in a holder 14, initially resting on the base of a cylinder 13 and the cover 12, which may be part of a web or a separate disc, placed over the cylinder mouth. It is then secured by an annular clamp 18 and a heater is sited above it temporarily. The heater is replaced by a spring-loaded plate 20 and the holder 14 is raised to press the container against the film and the plate. As the holder rises a low pressure space 15 is created which is in communication with the space between the container rim and the film margin. The margin is therefore drawn against the rim. In another embodiment, the container 10a is supported on a plate 16 with its neck surrounded by an annulus 21 having a seal ring 26 abutting the container. Prior to positioning the container, a cover 12 is placed on the annulus and heated as before from beneath the latter. A chamber 18 seats on the annulus from above and contains a piston 28 having a hollow shaft 30 through which its interior communicates with the atmosphere. When the container is in position beneath the heated cover, the piston 28 descends, pushing the cover on to the container mouth and about its rim. In so doing, it creates a low pressure space behind it which communicates with the space 22 about the container neck, via passages 23, 24, 27. The cover material is thus drawn against the neck.
Patent ES-349407-A1 (ES)
Title: Field Effect Transistor Amplifier Circuits
IPC: H03F3/347
Filed: 1968-01-17
Abstract: In an amplifier having a plurality of stages 10 1 , 10 2 ... 10 n connected in cascade, each stage consists of a common source connected insulated gate transistor 21, 14 which has a drain load impedance 20, 16 and the output 15 1 , 15 2 from each stage is connected to the gate of the succeeding transistor, the load impedance of at least one of the transistors is formed by the source-drain path of a further insulated gate field effect transistor 20 connected as a source follower and having the gate disposed to receive input signals and a feedback circuit 40 is connected between the output 15 n of the last stage 10 n and the gate 21g of the transistor 21 in the first stage 10 1 so as to provide a degenerativefeedback voltage. The feedback circuit may include an insulated gate field effect transistor 40 or this may be replaced by a resistor. Changes in the D.C. level at the output due to thermal effects, threshold voltage changes, supply voltage drift and component aging is fed back to the input 21g to provide degenerative feedback to compensate for these changes. The variations due to the A.C. signal, which may be at radio frequency, are filtered out by a capacitor 41. The load impedances of the 10 2 ... 10 n stages are shown as insulated gate field effect transistors 16 connected as diodes or alternatively these can each be replaced by a resistor. Several inputs can be connected to separate gate electrodes 20g, 16g 2 -(the earth connection to gates 16g 2 being removed), so that the output represents the combination of these inputs. The input signal can be disconnected from the first stage 10 1 in which case the gate 20g is connected to earth 12. Automatic gain control may be included in the circuit by connecting the source to drain path of an additional insulated gate field effect transistor between the gate and drain electrodes of one of the transistors 14. The AGC voltage signal is then supplied to the gate of the additional transistor. The input 17 1 to the amplifier may be fed from a source (70, Fig. 2, not shown) of slowly varying signal or D.C. signal via the conduction path of an enhancement type insulated gate field effect transistor (80) which conducts alternately with a further similar transistor (90). The input enhancement type transistors (80, 90) conduct alternately when their inputs increase above a certain threshold level and by connecting a detector circuit to the output of the amplifier, operating synchronously with the input transistors (80, 90) the output is converted back to D.C. The circuits may be constructed of individual components or may be formed as an integrated circuit. P or N type transistors may be used of the enhancement or depletion types. The input 19 may be a parallel tuned circuit of a transducer such as a microphone.

Title: System for treating uniform objects and a differential gear for such system
IPC: B67C7/00
Filed: 1969-04-25
Abstract: In a system comprising a plurality of stations 22, 23 for treating uniform objects (not shown), automatic conveying means 24 between the stations 22, 23, and storage means 25, 26 between a station 22 and the succeeding storage means 25, 26, and between the latter and the succeeding station 23 are provided respective counting devices 55, 52, which are coupled to each side of a differential gear 101 provided with a movable member 17 (Fig. 1) for recording the difference between the numbers registered by the two counting devices 55, 52, and controlling the output of either the station 22 or the station 23. The two respective counting inputs to the gear 101 are by means of shafts 4, 6. The shaft 4 is threaded and engages the internal threaded bore of the boss of a gear 7. The latter is in mesh with a gear 9 which is in splined engagement with the shaft 6. The two gears 7, 9, are coupled together by a member 9 which is rigid with a slide 10 mounted on a rod 11 and which carries a cam 12 co-operating with a follower 13 on an arm 14. A disc 17 pivotally mounted on the pivot axis 15 of the arm 14 is urged anticlockwise by a spring 20 so that a stop 18 of the disc 17 abuts a stop 19 of the arm 14. A spring 16 urges the follower 13 into engagement with the cam 12. Thus the disc 17 normally records the difference between the counting input to the shafts 4, 6, but this can be overridden by manual operation of an arm 21 connected to the disc 17. In Fig. 2, there are two sorting stations 25, 26, and counting devices 27, 37, and 28, 38, at their respective inputs and outputs. Differential gears 33, 43, connected to the counting devices of the respective sorting stations 25, 26, are connected to either side of a differential gear 46, the output of which is connected to a similar gear 49, the other input of which is from the counting device 52. The output of the gear 49 and the output of the counting device 55 are connected to the gear 101. This controls a regulating device 113 which controls an adjustment member 115 of the output of the station 22. As shown the stations 22, and 23, are for bottle rinsing and filling respectively.
Patent ES-357844-A1 (ES)
Title: Simultaneous multiple lead bonding
IPC: G02B13/08
Filed: 1968-08-27
Abstract: In a method of bonding electrical leads 21 extending from a workpiece to other leads 73, a beam of electromagnetic wave radiant energy is shaped with a pattern extending over the lead portions only at the locations to be bonded, the locations being external of the workpiece, and said pattern is applied simultaneously to said lead portions to effect bonding. In welding a plurality of leads 21 of a semi-conductor device to areas 73 on a substrate, a collimated energy beam 33 is shaped into four lines 24 circumscribing the perimeter of the body of the device, whereby the energy is focused and concentrated simultaneously only on the regions to be welded. The beam may be so shaped to any desired configuration using a lens 26 which comprises a member of cylindrical portions 31 each of which brings energy incident upon it to a line focus. The desired configurations may be, e.g. square, rectangular, triangular or polygonal. The cylindrical portions may be mutually spaced so that the desired configuration of the beam on the workpiece will be discontinuous, and in such cases a mask or masks may be used to prevent damage to the work or device by the non-focused parts of the beam. The size of the desired configuration of the beam on the workpiece may, for a given lens, be altered by the use of spherical lenses arranged between the lens 26 and the work to reduce or magnify the focused beam. The workpiece may be correctly positioned below the apparatus, and subsequently monitored, by closed circuit TV. In another embodiment (Fig. 10, not shown), the composite lens 26 is replaced by a mask (82) which shapes, but does not focus, the beam. The apparatus (Fig. 7) includes a rotatable holder 63 containing a number of different shapes of cylindrical lenses 26 any one of which may be selected for a particular application, and a further rotatable holder 61 carrying different lenses for altering the size of the desired configuration of the beam on the workpiece. The beam 33 may originate from a laser or from sources of infra-red or ultra-violet, or an incandescent arc or plasma source may be used.

Title: Patterning mechanism for knitting machines
IPC: D04B15/66
Filed: 1969-02-14
Abstract: In a circular or twin bed machine having needles or associated jacks bearing pattern butts, the butts are selected electromagnetically by means including selectors held in operative or inoperatives by mutual attraction of a permanent magnet and electromagnetic or electromagnetically influenced means. Each needle jack 17 comprises a spring extension 17c normally flexed outwards so that a lower butt 18 lies in the path of a raise cam 26. Pressers 19 fulcrumed in front of each jack force the butts 18 inwards prior to each selection where they are held by a magnet 30. The upper ends of selected pressers are now urged inwards as they pass the pattern unit, so that the butts 18 spring outwards. The pattern unit comprises a bank of selectors 35 pivoted to swing axially or tangentially relative to the needle cylinder. As shown an extension 35c of the selector forms the core of an electromagnet 38', pulsed by means of a pattern, and is thereby attracted by either one pole or the other of a permanent magnet 39. The electromagnet may be single or double wound, or comprises two axially spaced magnets. In a modification the extension 35c comprises a permanent magnet the far pole of which is selectively attractable by poles of an electromagnet. In one embodiment in which the selector moves tangentially an electromagnet fixed to it is attracted by permanent magnets on either side of it. In a modification the selector comprises the electromagnet core The pattern comprises a photoelectrically scanned punched tape having as many columns as feeds, and groups of rows in which each row corresponds to selectors disposed at a particular height. "Routing" pulses are provided by photoelectrically scanned holes (46a Fig. 7 not shown) in an axial extension of one of the tape drive rollers. The electromagnet is thus influenced either by the coincidence of pattern and routing pulses, or routing pulses only.
