Debajo de los lentes y a un costado de la mascarilla se instalo un micro ventilador, el cual al ser accionado por el usuario mediante un boton puede mantener fresco el interior y evitar tanto sofocacion como el empanamiento de los lentes protectores.
Patent ES-494440-A0 (ES)
IPC: A63B49/10
Filed: 1980-08-22
Abstract: A method of making a games racket frame by injecting thermoplastics material into the space (13) between a fusible core (14) and a mould at a temperature above the melting point of the core. The core (14) is shaped to have locating lugs (15) to abut against the internal walls of the mould and hold the core in the desired position. The moulding is allowed to set and the core then melted out by raising the temperature sufficiently for that purpose but insufficiently to deform the moulding. The lugs (15) enable the core (14) to be located in the desired position in the mould and to resist displacement from that location during injection. The holes formed in the wall of the frame because of the abutment of lugs and mould wall can conveniently be utilized as stringing holes.

Patent ES-526471-A0 (ES)
IPC: F15B15/02
Filed: 1983-10-14
Abstract: A force transmitting fluid actuator for use with a control device wherein an actuator member, movable within an actuator housing, actuates the control device due to the urging force of a plurality of pistons which can be selectively pressurized in unitary increments. The plurality of pistons are disposed within pressure chambers formed in the actuator housing in a symmetrical ring-shaped arrangement concentric to a single pressure chamber disposed on the vertical axis of the housing. A number of passageways interconnect the plurality of pressure chambers to form groupings of pressure chambers which act simultaneously in response to operation of a solenoid valve associated with each passageway. In addition to the symmetrical arrangement of the pressure chambers, the valve and passageway arrangement provide for a symmetric pressurization of the pressure chambers thereby resulting in a balanced force being exerted on the actuator. The amount of force each piston can exert on the actuator is limited by a piston stop designed to contact a portion of the housing while the actual piston force is transmitted by a spring disposed between each piston and the actuator. In this manner, fluctuations in the pressurizing force are not transmitted from the piston to the actuator.

Abstract: A digital multiplex radio transmission system wherein transmission channels between a fixed radio station and a plurality of mobile radio stations may be established by code division multiplex or frequency division multiplex, individual message channels being separated by means of different distributions of the data symbols transmitted therein. In order to synchronize the fixed station transmitter with the mobile station receivers, respective synchronizing symbols are inserted between the successive data symbols transmitted in any channel. The synchronizing symbols used in all channels are the same, and are spaced at the same time intervals in each channel. Consequently, they are received with significantly higher energy than the data symbols, permitting the multi-path profile to be measured and providing reliable synchronization.

Inventor: ANDERSSON CLAES
IPC: H04W52/00
Filed: 1992-05-15
Abstract: A mobile station is instructed to first transmit at relatively high sending power on a channel being assigned despite possible interference and is then instructed before a first time interval has elapsed to transmit at a more optimal power level to reduce interference. The power level on the channel is then periodically monitored at a second time interval greater than the first time interval. Momentarily increased interference is therefore tolerated in exchange for increased assurance of channel assignment. The interference is quickly reduced by implementing a fast power regulating function as compared to a slower ongoing channel power monitoring function.
