Title: Vhf-band amplifier for detecting cosmic particles
Inventor: ILIE IONUŢ-ALIN
IPC: H03F3/189
Filed: 2018-10-23
Abstract: The invention relates to an amplifier with the role of amplifying the spectral components in the frequency band of 30...80 MHz of the radio signals received by an antenna of a detector in order to increase the power of the signal. According to the invention, the amplifier comprises three amplification stages, each having a well-determined role, as follows: the first stage is used for taking over the input signal and increasing the current level thereof and it consists of a transistor (Q) connected in common emitter mode and having, as load, an impedance seen in the emitter of a second transistor (Q) and being polarized by a resistive divider (R, R, R), the second stage is used for voltage amplification and comprises the second transistor (Q) connected in common base mode having, as load, a resistor (R) mounted in parallel with an impedance seen in the base of a third transistor (Q), and the third stage is used for the adaptation between amplifier output impedance and the impedance characteristic to the coaxial cable through which the signal received by the antenna is transmitted towards the amplifier, as well as for the isolation of the relatively high impedance node at the output of the second stage, in relation to the relatively low impedance of the coaxial cable and it comprises the third transistor (Q) in collector follower configuration and it is pre-polarized by a bipolar current mirror with emitter degeneration by means of other two transistors (Qand Q).

Title: Method and device of the production of brushes
Inventor: WEIHRAUCH GEORG
IPC: B29C45/34
Filed: 2003-01-09
Abstract: The invention relates to a method for production of a brush from thermoplastic polymers. During the injection moulding, the polymer melt is injected under pressure into a brush-forming channel with given lengths and given cross-sectional change over said length and the channel ventilated during the injection process. According to the invention, injection-moulded brushes with excellent flexibility may be produced, whereby the injection pressure is set depending on the cross-section change in the brush-forming channel such that a shear flow with a high core speed in the centre of the polymer melt with a high shear effect as a result of the wall friction of the polymer melt with marked longitudinal orientation of the polymer molecules, at least in the region of the polymer melt near the wall, is generated and maintained along the length of the channel. The channel is simultaneously ventilated along the length thereof such that the shear flow is maintained. A device for carrying out said method is also disclosed.

Title: Method for obtaining adhesion between olefin copolymers or terpolymers and natural or synthetic rubbers
IPC: C08J5/12
Filed: 1965-07-20
Abstract: Adhesion, during co -vulcanization between layers of diene rubbers and layers of polythene copolymers or terpolymers, for example between tyre carcasses and tread or retread layers therefor, is improved by including in the diene layers a siliceous filler e.g. of anhydrous or hydrated silica, aluminium calcium or magnesium silicate, or kaolin, talc, clay or bentonite, and by selecting materials for the layers such that their " vulcanization starting times " are substantially the same and not less than two minutes. " Vulcanization starting time " is indicated in the Specification as the interval preceding that rise in viscosity of a mix, which is associated with the beginning of vulcanization. Diene rubbers usable include natural rubber, polybutadiene, polyisoprene and styrene-butadiene copolymers polythene copolymers and terpolymers include copolymers of ethylene with propylene or butene-1 and terpolymers formed from these materials and cyclic or acyclic non- conjugated dienes such as dicyclopentadiene or cyclo-octadiene-1,5. The customary vulcanizers, accelerators, fillers &c. for the layers may be used, e.g. sulphur and associated additives for the diene rubbers and organic peroxides and sulphur for the co- and ter-polymers. Organic peroxide may be used in both layers. Tyres.-In making tyres of a natural rubber carcase and ethylene-propylene copolymer tread a base layer of a natural rubber mix has applied to it a 1 mm. layer of a natural rubber mix containing anhydrous silica and a similar superposed layer of copolymer mix also containing silica, the two layers being pretreated with heptane, and finally a tread of copolymer mix containing carbon black, all applied layers cotaining an organic peroxide and sulphur and having a vulcanization starting time of between 2 hours and 2 hours 20 minutes. For retreading the above applied layer mixes are used, the prepared carcase having applied to it in succession (a) a heptane solution of the natural rubber mix, (b) a 1 mm. layer of such mix, (c) a similar layer of copolymer mix, layers (b) and (c) being pretreated with heptane, and (d) a tread layer as above.

Title: Thermostatic flow mixer
IPC: G05D23/13
Filed: 1967-07-20
Abstract: An axially movable valve member 3 is provided with a resilient independently-movable sealing washer 6 adapted to co-operate with seat 2 either as the result of movement of member 3 or under the control of solenoid-actuated valve member 13 which varies the pressure behind the washer, fluid has access to the rear of the washer via aperture 7 and projections 9. When the valve is fully closed, the rear of the washer obturates orifice 10. During normal use, the washer responds to variations in inlet pressure to maintain the flow rate constant. In the thermostatic flow mixer of Fig. 3, sealing washers 40, 41 operable as above to control hot and cold inlets 23, 24 are carried in pockets in an annular member 28 which is axially adjustable to determine the flow rate by handle 37 via nut 32. A thermally-sensitive plastics diaphragm 52 acts via pin 55 and lever 53 on pilot valves 44, 45 controlling washers 40, 41, the set temperature being determined by knob 62 which varies the load exerted on diaphragm 52 by spring 60. When fully closed, needles 72 in the inlets cooperate with the washer apertures 46 to define check valves. In Fig. 5, handle 37 effects axial adjustment of member 28 through a ball cage 76 co-operating with an inclined race 77. The thermally-sensitive diaphragm 52 is carried by rocking disc 74 which is coated at 75 to co-operate directly with orifices 42, 43. Leaf spring 73 loads disc 74.
