Title: Selectively removing basic nitrogen compounds from oils
Inventor: HABEEB JACOB JOSEPH
IPC: C10G29/06
Filed: 1982-02-16
Abstract: Hydrocarbon oil feedstock is mixed with an anhydrous non-polymeric Group IVb*, Group Vb, Group VIb, Group VIIb, nonnoble (iron group) metals of Group VIII, copper, zinc, cadmium, or mercury halide (except TiCl4 or FeCl3) or tetrafluoroborate, complexed with a non-aqueous polar solvent under conditions of agitation and mild heating whereby the basic nitrogen compounds (BNC) exchange with the polar solvent to complex with the above-recited metal halide or metal tetrafluoroborate. The oil is then decanted to separate it from the metal halide and BNC complexes and the decantate washed with a polar solvent, which preferably includes water, and dried. The preferred polar solvent for the wash step is water. The anhydrous non-polymeric metal halide or metal tetrafluoroborate-nonaqueous polar solvent complex can be used as such, or they can be impregnated onto a support material. * Periodic Table according to "The Handbook of Chemistry and Physics", published by the Chemical Rubber Publishing Company, Cleveland, Ohio, USA.

Title: Process and apparatus for supplying a plurality of consumers with metered amounts of a bulk material
Inventor: HEEP DIETER
IPC: B65G53/66
Filed: 1982-12-30
Abstract: In a process and apparatus for supplying metered amounts of a pneumatically conveyed bulk material from a common storage container (1) by way of separate conveyor conduits (9, 10, 11) the total quantity ( SIGMA  DELTA G) is determined by differential weighing of the container (1) and differential pressures ( DELTA p,  DELTA p2 DELTA p3) measured to obtain the actual flow of material in each of the conduits. Each of these is compared to reference value in respect of said flow, and the metering member (6, 7, 8) associated with the respective conveyor conduit is controlled, in accordance with the comparison result. To reduce the installation cost, the storage container (1) is connected directly and in parallel to the individual metering members (6, 7, 8) and the actual values are determined by means of a computer (21). <IMAGE>

Title: Banknote handling machines
Inventor: JENKINS STUART MCEWAN
IPC: B65H31/30
Filed: 1983-06-29
Abstract: In cash dispensing machines of the kind in which notes are delivered to a platform (2), mounted for movement about a pivot (5) between a first position in which it forms the base of the note- receiving device and a second "dump" position, the pivoted platform (2) is formed with a slot. When the platform is pivoted to its "dump" position, its slot passes over an underlying plate (7) of finger, which thereby projects through the platform and breaks the contacts between the surface of the platform and any banknote which has remained on the surface due to electrostatic attraction, for example.   <IMAGE>
Patent GB-2147947-A (GB)
Title: I.C. engine with water injection
Inventor: SPENCER PETER
IPC: F02B3/06
Filed: 1983-10-11
Abstract: Water is injected into the combustion chamber through a valve 14 during the compression stroke and the combustion/expansion stroke but not during injection of fuel through a valve 12. The amount of excess air introduced is reduced by an amount corresponding to the cooling effect of the water injection. The exhaust gas drives a turbine 16 which drives a compressor 17 which in turn compresses the air. The water is heated by heat exchange with the exhaust gas in a heat exchanger 24 and the compressed air in a contact heat exchanger 18. Values of water injection temperature and relative quantities of fuel and water, engine compression ratio, intake air compression pressures and excess air ratios are disclosed. <IMAGE>

Title: Apparatus for use in dispensing beer
Inventor: BETTERIDGE PAUL
IPC: B67D1/12
Filed: 1983-11-07
Abstract: One kind of apparatus for dispensing beer comprises a pump (6) which is operative to draw beer from a container and discharge it from a dispense head (11). The invention provides an air inlet (15) upstream of the pump so that in use air is sucked into the beer flowing from the container to the pump. The nitrogen in the air improves the quality of the head on the beer dispensed. The pump may be manually operated and the air inlet may be an adjustable needle valve. There may be a non- return valve upstream of the air inlet to prevent the gradual return to the container of beer that has previously been drawn from the container towards the pump. When the dispense head includes a sparkler this assists the formation of an improved head. <IMAGE>

Title: Electronic reading aid for the blind
Inventor: ISHIGURO SHIZUO
IPC: G09B21/00
Filed: 1984-01-26
Abstract: The aid, for "reading" ordinary printed letters or symbols, comprises an opto-electronic letter-image sensor 9, a rotating daisy-shaped wheel 3 having a pin 14 on each of its "petals" in a one-turn spiral pattern, and an electronic synchronizing system consisting of a marked optical disc 2 between the sensor and the wheel. When an element in the image sensor is activated, its output lifts a "petal" momentarily by electro-magnetic means so that the top of the pin goes above a threshold level 15, the synthesized position of the pins above the threshold forming the shape of the letter which is detected by the blind person's finger. The apparatus can contain a monitor (LED 17 and holes 18) for a sighted person to monitor the image of a letter. The apparatus can be made pocket-size including batteries. <IMAGE>

Title: Accelerometers
Inventor: BROWNING GEORGE WILLIAM
IPC: G01P15/12
Filed: 1985-02-20
Abstract: A sensitive accelerometer provides signals for use in stabilising the flight of a projectile such as a guided missile, but during launch of the missile, may be subjected to high shock accelerations which can damage its acceleration-sensitive element. An accelerometer which minimises the likelihood of such damage comprises a flexible beam 1 which is able to deform resiliently in the z- direction to measure acceleration in that direction and which is able to move as a whole in the x, y plane transverse to this direction. During launch the movement of inertial mass 2 causes the beam 1 and its supporting members 3, (4), to pivot about one of edges 7, 8 until restrained by one of abutments 9, 10. The beam is returned to its central position under the action of spring 11 when the high acceleration phase is past. <IMAGE>

Title: Tufting machines
Inventor: INGRAM GARY L
IPC: D05C15/20
Filed: 1985-07-22
Abstract: A tufting machine has a cam (64) mounted eccentrically on a main drive shaft (30) about a center of rotation that may be varied by linear movement of the cam relative to the shaft by a slot (80) elongated about a radial line to change the stroke of the needles without changing the timing of the needles (24) relatively to the loopers. Locating plates (66,68) fastened to the shaft have hubs (86,88) received in the slot (80) at preselected positions, the cam and plates having indexing holes (82,102) that can be selectively aligned for the desired needle stroke.
