Patent ES-477507-A1 (ES)
Title: Enhancements in the preparation of milk density analysis tests.
IPC: G01N/
Filed: 1979-02-06
Abstract: The object of this invention is to build a system to obtain and have complete control over the aforementioned preparation of samples, including a constant removal of both the sample flasks and also the heating and cooling liquid, an operation that will result in greater yield and speed in obtaining the desired temperatures. The invention consists of a table, provided with different control mechanisms that contain a tray the base of which has a grating which vibrates. The flasks that contain the milk samples to be analysed will be placed on this grating, so that the vibration of the grating is transmitted to the flasks, so that with this motion the act of thermal transmission produced by the liquid situated in the tray is aided. This liquid can reach it through pipes, for hot or cold water, each of which comes from its corresponding tank, one of them having electrical resistors for heating and the other having a refrigeration system. Thermostats are positioned on the inside of the flasks carrying the samples, which will govern their corresponding switching valves in such a way that one of these thermostats reverses the functioning of the switching valves when the content of the flasks reaches the upper temperature limit for the test, while the other thermostat detains the system when the sample has reached the optimum lower temperature limit. Thereby, automation of the milk testing process is achieved, contributing an extremely functional and integrated setup that will produce the improvements referred to previously.

Title: Multi-speed transmission for bicycles.
IPC: C07C49/813
Filed: 1979-12-13
Abstract: A multi-speed bicycle transmission located in the pedal hub and actuable through the drive pedals. Drive gears (92, 94, 96) are rotatable about the pedal shaft (32) and can be selectively brought into driving engagement with the shaft by means of a mechanism including a shiftcollar (312), the axial position of the collar along the pedal shaft determining which drive gear is engaged. A shift pin (308) extends into the hub from a tubular frame member and is displaceable radially against a spring (310). Inclined camming channels (320,322) in the shift collar (312) cooperate with the shift pin and are shaped to effect longitudinal displacement of the collar upon reverse rotation of the pedal shaft. On forward rotation of the pedal shaft, the shift pin (308) is forced radially outwardly and no longitudinal displacement of the collar is effected.

Title: A device for spreading whole tobacco leaves.
IPC: A24B5/14
Filed: 1981-05-11
Abstract: A device for spreading tobacco leaves comprises a suction box with a perforated wall and a shield composed of a plurality of sections transversely movable outwards from a closed position in which they cover the perforated wall with the exception of a central area against which the mid rib portion of the tobacco leaf can be clamped by means of a rail. The leaf is held by suction against the shield sections during their opening movement and is so spread and stretched transversely in a direction away from the mid rib. Trailing brushes that are moved outwards together with the shield sections are further provided for this purpose. The perforated wall may comprise knives which, when being run over by a roller, cut out wrappers or binders or blanks therefor from the tobacco leaf while this is still being held firmly against the wall after full opening of the shield.

Patent ES-8205299-A1 (ES)
Title: Universal rotating machine for expanding or compressing a compressible fluid.
IPC: F01C1/20
Filed: 1981-08-21
Abstract: A pair of tangential rotors are provided on separate shafts dependently rotatable in a housing, one having a vane and the other a notch for allowing passage of the vane, to form a fluid-tight segmented annular region through which the vane moves. A valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion, or from the region after compression, the mass of fluid being confined in a portion of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and thus volume of the confined region portion. Multiple pairs of rotors may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.

Title: Method and electric circuit for suppressing radio interference generated by apparatus and installations driven by electric motors
IPC: H02K11/00
Filed: 1984-02-02
Abstract: A method and electric circuit for suppressing radio interference comprises an electric circuit for connecting and starting-up an electric asynchronous motor M1 used on automatic washing machines or on other appliances. The inductance of the motor windings L1 and L2 is used as part of the noise filtering circuit. The contacts c2 for controlling the motor are connected between separate parts of the stator windings L1 and L2.

Title: Forming bead seal in biaxially oriented polymer film by heat bonding
IPC: B29C65/02
Filed: 1984-12-14
Abstract: Apparatus and method for heat sealing a selected segment of a web of at least two layers of biaxially oriented plastic film. The web layers are pressed together and a selected segment of the pressed web is heated above the bonding temperature of the plastic while adjacent web segments are maintained below that temperature. The surfaces pressing thus the heated web segment has a relatively lower surface friction than the surfaces pressing the adjacent web segment, whereby the layers of the heated segment of the web are physically unrestrained against shrinking during heating and are allowed to shrink back to their pre-oriented molecular configuration while the adjacent segment is restrained against movement. A hermetic bead seal is thus formed between the web layers. A product heat sealed according to the novel method is also disclosed.
