Patent GB-2104746-A (GB)
Title: Radio frequency transmitter
Inventor: BLYTHE MALCOLM RICHARD
IPC: H03C7/02
Filed: 1981-08-10
Abstract: An R.F. transmitter has a digital power phase shifter (13) located between the output (11) of an R.F. power generator (10) and an antenna (12). The power generator produces power at a predetermined frequency and constant phase. The phase of the power radiated by the antenna can be digitally coded by a code generator (24) controlling the phase shifter (13). The phase modulator comprises three delay lines (14, 15, 16) in parallel with RF power switches (17, 18, 19) such as PIN diode switches. The arrangement obviates the need for amplifying the coded output. <IMAGE>

Title: Improvements relating to tape handling mechanism
Inventor: KNOTT JOHN
IPC: G11B23/04
Filed: 1981-09-11
Abstract: A tape handling mechanism (1) suitable for handling magnetic tape comprises a housing containing a first hollow (5) and a second hollow (6) linked by a substantially airtight C- shaped passageway (14). The first hollow includes a driven take-off spool arrangement (7) having a perforated hollow axial spindle. A number of apertures (21) are located at a second location adjacent thereto. The second hollow includes a driven supply spool (12) having a length of magnetic tape (9) wound thereon. A number of apertures (20) are located at a first location adjacent the second hollow, within the passageway. In use, a vacuum system applies suction in turn to the first location and then to the second location and spindle to produce an air flow past a door (14) and through the passageway sufficient to drag unwinding tape therethrough, past cleaning means (30), reading means (19) and guide means (15, 16, 17) and onto the rotating take-off spool arrangement. <IMAGE>

Title: A floating offshore platform
IPC: B63B35/44
Filed: 1981-10-09
Abstract: In order to make possible a rescue of the staff of an offshore platform in case of disaster, at least one housing (16) including staff accommodation is freely mounted in a recess (18) in the deck (10) of the platform. The housing is erected integral with a double bottom (17) having a sufficient buoyancy to carry the housing floating free of the remainder of the platform. The double bottom preferably extends outside the side walls of the housing, and reaches a distance up along the latter to form a first girdle (19). A second girdle of displacement bodies (20) is located about at the half height of the housing to prevent the platform from tilting over. The two girdles are sub-divided into tanks and will serve as fenders against the platform structure, when the housing is set free. <IMAGE>

Patent GB-2086233-A (GB)
Title: Microsurgical scissors
IPC: A61B17/28
Filed: 1981-05-04
Abstract: A microsurgical scissors uses a rotary cutting action and biased blades (13, 14) that intersect in a travelling point of contact. One blade (13) is situated on the end of a tubular shaft (11) and a second blade (14) on a rod (12) that is rotatable within the shaft (11). The blades (13, 14) are angled so the blades intersect at a point of contact. To assure a precise shearing relationship, the rod (12) is biased rearward in order to bear the rod blade (14) against the shaft blade (13). An actuating mechanism (23, 25) in the handle (10) translates a linear finger motion into rotary motion of the rod. The blades (13, 14) cut clearly and surely without imparting undue tissue trauma.

Patent GB-2121971-A (GB)
Title: Battery state of charge evaluator
Inventor: CODD ROGER DENNIS
IPC: G01R31/36
Filed: 1983-06-02
Abstract: A combined battery state of charge evaluator and motor control system for an electric vehicle comprises a traction battery 10, a motor controller 14, a traction motor 11, a micro computer 16 and an interface circuit 15. The micro computer 16 receives signals representing battery temperature, total battery voltage, and battery current and calculates the charge withdrawn from the battery by integrating battery current and also calculates the remaining charge in the battery as a function of battery voltage. By summing the remaining charge and the charge withdrawn, the present charge storage capacity value of the battery is calculated. The micro computer 16 compares the present charge storage capacity value with a value representing 85% of the nominal charge storage capacity of the battery when new and selects the lower of these two values. The state of charge is then calculated as a function of the charge withdrawn and this lower value and displayed on a meter 34. When the remaining charge in the battery calculated by subtracting the charge withdrawn from this lower value falls below 6% of the battery capacity, the current supply to the motor 11 is limited to a predetermined percentage of the current demanded by the driver. This predetermined percentage is progressively reduced as the remaining charge falls towards zero. <IMAGE>
