Patent GB-2151804-A (GB)
Title: Testing film transport mechanisms
Inventor: BRANSON ARTHUR
IPC: G03B1/42
Filed: 1985-02-01
Abstract: A cine film transport mechanism is tested for picture steadiness by producing a first colour component of an output image on a film and comparing with a second contrasting colour component of the output image produced on the same portion of film during a 2nd exposure as reference. The colours may be green and magenta. The test image is a "flat staircase" having two regions of the different colours, separated by white or black regions, the distance between the two colour regions varying along their lengths, preferably in an incremental manner. Testing may be effected automatically by comparing the "heights" of the white and black regions of the output image. With a reference via detectors arranged about these portions (see Figure 4 - not shown). <IMAGE>

Title: Testing stored equipment
Inventor: LOOMER WESTON RONALD
IPC: B65G1/137
Filed: 1985-04-24
Abstract: Items such as components or assemblies of equipment (printers, computers, recorders, etc.) may be subjected to burn-in or other test procedures while in storage in a system which utilizes racking and a stacker-retriever vehicle (with shuttle table assembly) for placing item carriers (31) at selected storage locations. The item carrier (31 - Figure 4a) includes means to connect the item to power and control inputs; as well as a power and control connector (100) connectable to power and control connectors (102) located at each of a number of test locations (44) within the racking. The shuttle table assembly in one embodiment, following placement of the item carrier in the test storage location, is raised up to engage the face of the item carrier and to move the item carrier so as to mate the item carrier power and control connector with the connector of the storage test location. When the shuttle table assembly is operated to retrieve the item carrier it is first inserted into contact with an item carrier disconnect device and operates same to move the item carrier so as to effect disconnection of the mating connectors. <IMAGE>

Patent GB-2177765-A (GB)
Title: Improvements relating to automatic transmission systems
Inventor: BISHOP ROBERT
IPC: F16H61/66
Filed: 1986-06-16
Abstract: An automatic transmissions system for a vehicle has an infinitely variable transmission (29) driven by an engine (30). This transmission may be an epicyclic gear train in parallel with a hydraulic pump/motor unit whose output can be clutched to different gears of the train to produce forward and reverse drive, or be disengaged for neutral. A computer (36) receives information from transducers (37, 38, 39, 40, 41, 42) for the braking, acceleration, engine speed, vehicle motion and oil situation, and also from a selector (21) on the chosen mode of operation (forward, reverse, neutral). Through a servo (15), the computer governs the pump/motor unit and thus the transmission. It is programmed so that smooth clutch engagement is achieved once the mode is selected and, at least in the forward mode, to maintain the engine in a predetermined efficiency band. A further forward more can be provided where more power is available at less efficiency. <IMAGE>

Title: Wind turbine operating system
Inventor: LAWSON-TANCRED BT SIR HENRY
IPC: F03D7/02
Filed: 1988-07-12
Abstract: A variable speed wind turbine operating system comprises a speed limiting system comprising turbine 11, driving an alternator 16 via a gearbox 14, a controller 19 and a shaft mounted brake means 13. The turbine has a rated condition and a speed/torque characteristic such that when wind speed increase tends to run the turbine above its rated condition, the brake is applied to slow the turbine to a speed at which the blades are operating so inefficiently that further wind speed increase cannot increase shaft speed or torque unacceptably. The brake may be a disc brake the hydraulic calipers of which are supplied with fluid pressure by a pump driven by the turbine. In alternative arrangements the brake is replaced by means for retarding the shaft such as an electrical generator (Fig 5) driving a switchable resistive control load. Alternatively generators having variable pole arrangements may be used (Fig 6). Alternatively two similar generators may be used with variable connections to a supply grid (Fig 7). <IMAGE>
