Patent GB-2278553-A (GB)
Title: Oil skimmer
Inventor: DOREY MICHAEL JAMES
IPC: E02B15/10
Filed: 1993-06-02
Abstract: An oil skimmer has a circular hopper 1 with a peripheral weir 2 and an inwardly sloping inner wall 3. An aperture 4 at the bottom end of the hopper 1 feeds the collected oil to a pump 5 connected to a discharge hose 6. Floats 14, 15 and (16) support the skimmer at a height when floated in water such that the weir 2 is just below a nominal water level 17 so that oil floating on the water will pass over the weir 2 into the hopper 1. A weighted body 18 with a lower wall 20 parallel to wall 3 is suspended within the hopper 1 from a superstructure 22 by a hydraulic cylinder 23 whereby the level of the weighted body 18 with respect to the hopper 1 can be varied to change the degree off immersion of the body 18 and hence the effective weight of the skimmer as a whole. This will vary the height of the lip 2 with respect to the water level 17, i.e. raising the body 18 will lower the lip 2 with respect to the water level 17. <IMAGE>

Title: Coin selector
Inventor: ECHAPARE IBARROLA JESUS
IPC: G07D5/08
Filed: 1993-06-04
Abstract: A coin selector is switched from standby to operative mode when a coin 6 fed into the selector engages and moves a rocker arm 1 carrying a mobile permanent magnet (3) to actuate a fixed magnetic relay (4) close to that magnet. The displacement of the rocker arm pulls the magnet, varying the action of the magnet's magnetic field on the relay. The relay is connected to a power supply circuit for the sensor, which connects when a coin is introduced. <IMAGE>

Title: A hydrocarbon fuelled fuel cell power system
Inventor: GARDNER FREDERICK JAMES
IPC: H01M8/06
Filed: 1993-06-30
Abstract: A hydrocarbon fuelled fuel cell power system (10) comprises a fuel cell stack (12), a reformer (14) and a hydrogen store (16), the reformer (14) being arranged periodically to supply reformate, which contains hydrogen, to the fuel cell stack (12) and to the hydrogen score (16), the hydrogen store (16) being arranged to store the hydrogen from the reformate during the periods that the reformer (14) operates, and the hydrogen store (16) is arranged to supply hydrogen to the fuel cell stack (12) during periods of low load demands on the fuel cell stack (12) and is capable of supplying hydrogen rapidly to the. fuel cell stack (12) for high load demands on the fuel cell stack (12). The hydrogen store (16) also supplies hydrogen to the reformer (14) to light up the reformer (14). The hydrogen store (16) buffers the fast response of the fuel cell stack (12) and the relatively slower response of the reformer (14) during relatively large rapid demands on the fuel cell stack (12) and enables the reformer (14) to be operated in an on/off mode. <IMAGE>

Title: Mechanical manipulator
Inventor: BAILEY RALPH PETER STEVEN
IPC: B23Q5/40
Filed: 1992-04-06
Abstract: A computer aided design and manufacturing system comprises a platform (7) suspended by means of three pairs of supportive legs (8) which are coupled thereto at triangularly spaced-apart locations by means of three universal joints (9) each of which couples to one end of each of the two legs (8) of a respective pair, the two legs (8) of each pair extending from their respective universal joint (9) in divergent directions to spaced-apart locations in an overhead mounting whereat each leg (8) is drivingly engaged by a respective gimbal-mounted electric motor (10) arranged to move the leg (8) in its own longitudinal direction. The platform (7) position and orientation can thus be controlled by appropriate operation of the six leg drive motors (10). A rotary indexing stage (11) is mounted on the platform (7) for rotation in the plane of the platform (7) under control of a further electric motor (149, 150) and serves as a mounting for a stage (12) providing for pivotal movement in a plane perpendicular to the plane of rotation of the indexing stage (11), such pivotal movement being effected under control of yet a further electric motor. Mounted on the pivotal stage (12) is a rotary tool holder (13) arranged to be driven by yet another electric motor (75). The various electric motors are precisely positionable under computer control for effecting automatic manufacture of an object by cutting the same out of a block of material by means of a tool held in the tool holder (13).
Patent GB-2272499-A (GB)
Title: An air spring unit
Inventor: GROLL EMANUEL
IPC: B60G17/015
Filed: 1993-11-08
Abstract: An air spring unit with a main chamber F (or 4) which varies in its volume during movements of the spring also has an additional chamber K (or 7) which exhibits an essentially constant volume and which, by means of a valve 6, can be connected to or disconnected from the main chamber F to vary the progressivity of the suspension. This valve 6 exhibits a virtually unthrottled opening position, from which it can be rapidly closed; on the other hand, the opening of the valve is performed with a delay, in that initially it runs through a pre-opening phase, permitting only small flows, to delay pressure equalization between chambers F and K. The valve is controlled by pressure applied in chamber 17. <IMAGE>

Title: Shopping cart
Inventor: REHRIG HOUSTON
IPC: B62B3/14
Filed: 1994-08-03
Abstract: The cart has a molded plastic basket 3, a U-shaped art handle tube 5 and a reinforced plastic molded lower support structure 7. A basket support wire 17 braces the basket against the cart handle tube and lends rigidity and strength to the basket. The support wire has legs 19 that extend within respective channels 21 provided along opposing side segments of an upper peripheral edge portion of the basket, less than the entire lengths of the opposing side segments. Bent end portions 23 of the legs, extending into openings provided in the basket peripheral edge portion, fixedly secure the support wire to the basket. A cross-arm portion of the support wire 27 connects the legs 19 and engages the cart handle tube. Upper leg portions 11a of the cart handle tube extend downwardly along a rear panel of the cart basket. Lower leg portions 11b of the cart handle tube extend along rear edge surfaces of the lower support structure and provide at their ends wheel assembly mounting locations. A pair of metal reinforcing rails (57, Fig. 3) extending within a horizontally extending base member 29 of the lower support structure are coupled at rear ends thereof to respective lower leg portions of the cart handle tube, and at opposite ends to a front wheel assembly mounting plate. The cart construction facilitates assembly from a knocked down state of basket, handle tube, support structure 7 and wheel assemblies 13, 71. <IMAGE>

Patent GB-2306087-A (GB)
Title: Processing audio signals
Inventor: TILLETT OLIVER STEPHEN
IPC: H04R5/04
Filed: 1995-10-09
Abstract: A circuit arrangement usable with a radio receiver, particularly a receiver receiving telegraphic signals, to function as a fine tuning device receives audio signals from the receiver. The audio signal is inputted to a cross-over network (10) with band pass filters so that frequencies above a selected value (Fc) are transmitted through a first channel (Fc+) and frequency below the selected value (Fc) are transmitted through a second channel (Fc-) but with a time delay. The first and second channels drive a set of stereo headphones (12) and when the receiver is accurately tuned onto a radio signal at the selected value (Fc) an echo occurs at Fc which enhances the wanted signal.
