Abstract: A high voltage bidirectional output semiconductor field effect transistor (BOSFET) 24 is disclosed which is turned on from the electrical output of a photovoltaic stack 19 which is energized from an LED 21. The process for manufacture of the device is also disclosed. The BOSFET device consists of two lateral field effect transistors 30, 31 formed in an implanted N( - ) region (71) in a P( - ) substrate (70). A diode 35, PNP transistor 36 and resistor 37 are integrated into the same chip containing the lateral BOSFET device to form a solid state relay circuit having characteristics similar to a reed relay. A photovoltaic isolator 20 consists of a stack of semiconductor wafers (320) which are alloyed together by an aluminum silicon alloy foil (43). Each of the wafers consists of a P-type body having P + and N + diffusions on its opposite surfaces. The wafers are stacked with the same forward conduction polarity. Individual photoisolator stacks (345) are sliced from the completed stack to any desired dimension.

Abstract: A membrane distillation module is provided with a thin, flexible microporous P.T.F.E. membrane (16) positioned against an impermeable condensor sheet (12) that is stiffer in bending than the membrane. Distillate vapour diffuses through the membrane from a hot feed flowing rapidly past the membrane, and condenses and collects between, and in intimate contact with, the membrane and the condensor sheet. The condensed distillate is stripped by forces exerted by the hot feed acting on the distillate across the membrane, and flows toward a distillate outlet (40) located in the downstream direction of the hot feed flow. Cold feed flows past the condensor sheet in the counter direction to that of the hot feed.

Abstract: Reactive antioxidant compounds, able to stabilise organic polymers, contain in their molecule a sterically hindered phenolic group and a hydrolysable silyl function. 
<??>In stabilising organic polymers, said reactive antioxidant compounds can be hydrolysed at the silyl function with the formation of silanol groups, which are made to interact in order to form complex resinous stabilising structures. These latter are added in stabilising quantities to the polymer to be stablised. 
<??>According to one particular embodiment, the hydrolysis at the silyl function and the formation of the resinous structure take place spontaneously within the polymer to be stabilised. 
<??>According to a further embodiment, the reactive antioxidant compound is added to the polymer after being stably supported on a solid support by reaction with an inorganic solid having surface hydroxly groups. 
<??>According to a further embodiment, the reactive antioxidant compound is made to interact with the polymer so that the stabilising compound becomes chemically bonded to the polymer chains. 
<??>In all cases, stabilised polymers are obtained containing the antioxidant compound in a form which is not removable from the polymer. 
<??>The process for preparing the reactive antioxidant compounds and for preparing the stabilised polymer compositions are also described.

Abstract: PCT No. PCT/DE80/00059 Sec. 371 Date Jan. 9, 1981 Sec. 102(e) Date Jan. 9, 1981 PCT Filed May 8, 1980 PCT Pub. No. WO80/02548 PCT Pub. Date Nov. 27, 1980.During the winding of coils with a non-circular shape the wire length necessary varies periodically for a trouble-free winding per unit of time. At a high winding rotational speed and unsatisfactory side ratios relative to the coil being wound, the periodic change in the required wire length is so large that with known wire brakes there is no adequate winding quality with a concurrent protective handling of the wire. These opposite goals are reached through the invention with the aid of a controllable wire brake which essentially consists of a plurality of brake strands wound about the wire in a single layer.

Title: Cord fabrics dyeing machine
Inventor: CHIEMENTIN ALDO
IPC: D06P/
Filed: 1984-07-20
Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.
