Patent EP-0183420-A2 (EP)
Inventor: RISK WILLIAM P
IPC: G02F1/01
Filed: 1985-11-11
Abstract: A fiber optic amplitude modulator couples light between two orthogonal polarization modes of a birefringent fiber (200, 230, 250, 270, 304). Dynamic coupling is caused by applying synchronized acoustic surface waves to the birefringent fiber (200,230,250,270,304) in a direction normal to the fiber axis. A static biasing force (F) is applied across the fiber (200, 230. 250, 270, 304) to statically couple approximately 50% of the light input to one polarization mode into the other polarization mode. The additional force caused by the acoustic waves (205, 275A, 275B, 275C, 302) causes the fraction of coupled power to vary about the coupling caused by the static force (F).

Abstract: 57 An automatic banknote depositing apparatus comprises a casing or housing (1) and transport means for transporting banknotes from an infeed opening (10a) to a cassette (11). The infeed opening (10a) is covered by one (14) of a plurality of insert devices when the apparatus is complete. The housing (1) has located adjacent the infeed opening (10a) a recess adapted to accommodate the insert device, and the insert device is provided with a pressure means (21) for bringing pressure to bear mechanically against banknotes, and a keyboard for controlling the apparatus. 
     One of the insert devices (14) forms, together with the housing (1) an externally accessible opening (10c) intended for manual insertion of banknotes. The insert devise has a vertically displaceable bottom member (22) which, when occupying its upwardly displaced position, forms an inclined surface, which extends down to the infeed opening (10a). 
     Another of the insert devices (40) incorporates a slatted roll-shutter (42) which can be moved automatically into and out of the body of the insert device and which when only partially inserted into the device exposes a narrow opening through which banknotes can be manually inserted, while when fully inserted into the device exposes a large opening through which a cassette can be inserted. The pressure means in the form of a plate (21) can be dropped down automatically in the bottom member (22) when the slatted roll-shutter is fully displaced into the insert device.

Abstract: A dispenser for beer or the like comprising a container filled with a beverage having carbon dioxide in solution to between about 5/8 to 3/4 of its volume, the head space above the beverage being filled with a gas under pressure. 
     When liquid is dispensed from the container the loss of C0 2  dissolved in the liquid is less than that in dispensers known hitherto because the pressure in the head space remains relatively high and consequently less CO 2  comes out of solution with the liquid. Hence a dispenser having a substantial head space significantly increases the ability to dispense relatively large volumes without requiring any significant restoration time.

Abstract: Electrode materials and method for their surface activation are described. Alloys consisting of at least one element of the group consisting of Nb, Ta, Ti and Zr, at least one element of the group consisting of Ru, Rh, Pd, lr and Pt, and balance being Ni are prepared by methods for preparation of amorphous alloys, and are amorphous or supersaturated solid solution. Their surfaces are activated to enhance electrocatalytic activity by enrichment of electrocatalytically active platinum group elements in the surface region in addition to surface roughening as a result of selective dissolution of Ni, Nb, Ta, Ti and Zr from the alloys during immersion in corrosive solutions. The surface-activated amorphous and supersaturated solid solution alloys possess high electrocatalytic activity and selectivity for a specific reaction as well as high corrosion resistance.

Abstract: A scanning system for a phased array antenna for operation at a selected frequency between a first frequency and a second frequency includes the storage (50) of phase shift command signals for each of the phase shifters (24) coupled to radiating elements of the antenna. The memory (34) which stores the phase shift commands is addressed sequentially to provide for a step-wise scanning of a beam of radiant energy at a first frequency of the antenna. The addressing (46) is accomplished by incrementing a count resulting from a counting of clock pulses (40). Compensation for the stepped positions of the beam for the difference between the selected frequency and the first frequency is accomplished by altering the number of pulses (54) which increment the count of the addressing. The altering is accomplished by the storing (50) of sequences of clock pulses at varying temporal spacings which are used for gating (44) out selected ones of the incrementing pulses.
