Patent GB-2199006-A (GB)
Title: Article-transfer equipment
Inventor: WORSWICK ALAN
IPC: B65G47/90
Filed: 1986-11-03
Abstract: Articles such as hot metal ingots are individually picked up from a conveyor 2, at a pick-up location 3 by lowering, closing and raising a vertically moveable grab beneath end 5a of an arm 5 vertically pivoted at 4, or beneath an end of a reciprocable beam. The arm or beam also possesses an end 5b with an identical grab which simultaneously with movement at 5a is lowered, opened and raised to locate a previously picked-up article at the top of a stack at 6. Reciprocation of the beam, or rotation of arm 5 about pivot 4, between such lowering/raising cycles thus ensures a stacking operation at twice the throughput of a machine with a single grab. <IMAGE>

Title: Selective printing apparatus
Inventor: YUMOTO MAKOTO
IPC: B41J25/24
Filed: 1987-05-28
Abstract: A selective printing apparatus (such as a printer of the type using a type wheel) includes two guide members which extend between a pair of side frames and each of which is fixed by "caulking". A carrier is slidably mounted on the guide members. A carriage loaded with a type wheel and others is mounted on a carrier in such a manner as to be rotatable by 90 degrees between a predetermined print position and a wheel replace position behind the print position. A sensor for determining the presence/absence and the kind of a type wheel loaded in the carriage is provided. The term "caulking" appears to relate to a method of joining in which a tongue on one part is passed through a slot in the other part, and wherein the tongue is subsequently plastically deformed. <IMAGE>

Title: pH controller
Inventor: SMYTHE M J
IPC: G01N27/416
Filed: 1988-03-10
Abstract: A pH controller for a liquid stream includes a pump (22) to inject a pH-changing additive into the stream, a mixing chamber (38), an electrode (18) to measure the pH of the emerging liquid, and means to adjust operation of the pump in accordance with that measurement. The mixing chamber (38) is of annular form, defined between two concentric cylinders (30, 34) the inner one (34) of which is rotated. The rotation speed and the throughput can be adjusted to give very thorough mixing and hence to enable the pH to be held at a steady value. The flow regime appears to involve Taylor vortices (40) which together define a single helical path for the liquid. The liquid treated may comprise effluent form nuclear fuel reprocessing (e.g. containing nitric acid and ferric nitrate) to which is added NaOH solution to achieve a pH of 9-10.5, to precipitate ferric hydroxide floc. <IMAGE>

Title: Interferometry
Inventor: ASHWORTH DAVID MICHAEL
IPC: G01D5/26
Filed: 1989-04-04
Abstract: An interferometer having a sinusoidal transfer function is provided with a feedback system serving to maintain it at phase quadrature. An ac bias signal of frequency fo is imposed on the signal to be measured by the interferometer and the component of frequency 4fo extracted from the interferometer output. This 4fo component is zero at phase quadrature. Means (13, 16) are provided to change a parameter of the interferometer in response to the 4fo component whereby to drive it at least towards zero and to a minimum value. In the case of a magnetometer for measuring dc magnetic fields, the fo component of the interferometer output provides a measure of the dc field. A magnetostrictive material (7) may be addressed by a free space optical beam output from a fibre (5) with the distance between the material and the fibre varying with magnetic field. In this case the parameter to be changed may be the position of the output end of the fibre (5). <IMAGE>

Title: Controlling a property of a mixture
Inventor: ELVEBU KOLBJ RN
IPC: G05D11/13
Filed: 1989-04-26
Abstract: To control a property such as the density of drilling mud or other mixture supplied from a container 6, the density is measured at 17, 18 or at 25, and a level sensor 23 measures the quantity of mixture in the container. A control unit 22 then calculates how much of an additive in storage tank 3 needs to be added to a set fraction e.g a third of the measured quantity to bring the density of that fraction to a desired level. The calculated amount is then dispensed by reference to weighing cells 19 and mixed with the mixture. The resultant density and quantity are then measured again and the whole process is repeated until the density falls within determined limits.   <IMAGE>

Title: Antenna apparatus for infrared and millimetre-wave radiation.
Inventor: EVANS DAVID HILLARY
IPC: H01Q5/22
Filed: 1991-02-15
Abstract: A simplified construction of an antenna apparatus for both infrared and millimetre-wave radiation is obtained by embedding the infrared detector (2) in a mm-wave lens (3). The lens (3) of, for example, polystyrene transmits the mm-wave radiation to and from the transceiver (1), and the lens performance is not seriously degraded by the embedded detector (2) or its connections (33) or even by a cooler pipe (37) of the infrared detector (2). As well as providing reliable mounting of the infrared detector (2), the arrangement permits the mm-wave transceiver (1) to be located on the optical axis of the lens (3) in a coaxial concentric arrangement for viewing a common scene at both the infrared and mm wavelengths through a common aperture. <IMAGE>

Title: Operation of an internal combustion engine
Inventor: MA THOMAS TSOI-HEI
IPC: F01N3/36
Filed: 1991-11-22
Abstract: A method is described of operating an internal combustion engine burning a fuel containing carbon and hydrogen, to provide a flame in the exhaust system to heat a catalytic converter or burn off the soot in a particulate filter trap. The method involves reducing the intake throttle opening during deceleration mode below the throttle opening for the steady speed idle position to create a proportion of combustible gases in the exhaust gas stream. By ensuring at the same time the presence in the exhaust gas stream of additional air, an ignitable mixture is produced which is ignited to burn as a flame in an afterburner chamber of the exhaust system. By selecting deceleration periods to enrich the mixture excessively in this manner, adverse effects on drivability go unnoticed. Secondary air may be supplied by pump 30, scoop 34 or by the turbocharger 28 via by-pass 39. Electronic control unit 48 responds to detection of deceleration by opening appropriate air supply valve 32, 36 or 38, closing throttle 24 and causing igniter 18 to spark. <IMAGE>

Title: Improvements in or relating to steam driven vehicles
Inventor: HALLAM RICHARD GRENVILLE
IPC: A63H19/14
Filed: 1991-12-27
Abstract: A live steam driven model railway locomotive is connectable through rails on which it runs to an electric power source which is used to raise steam. The model may be remotely controlled by adjustment of the power supply. A displacement lubricator 51 is associated with the model's piston/cylinder arrangement 50 such that steam driven piston movement causes lubricant to be transferred from a reservoir 42 to the cylinder 50. The electric power supply generates superheated steam by means of two heating elements 10, 11 located within boiler 12 and superheater 13 respectively. The boiler is suitably housed within the tender and connected via a flexible steam pipe to the locomotive. <IMAGE>
