Title: Pocket size international currency guide
IPC: G07D5/00
Filed: 1981-04-01
Abstract: A manufactured article that can be called pocket sized which will give immediate information as to the exchange value for goods and services in a country whose coins and currency notes are different from that of the person using the guide. Coins will be identified by being placed in a depression in the guide that will fit its size and shape. The coin depression will show a number allocated to that particular coin. The number when referred to in the printed instructions will give the exchange value and also illustrations of the front and back engraving of that coin to aid identification. Currency notes will be illustrated and exchange values given, subject to the legal requirements governing the photographic duplication of illustration of currency notes.

Title: Astigmatism compensated optical scanning refractive polygon
IPC: G02B5/09
Filed: 1981-05-14
Abstract: An optical scanning device for the production of cartesian images with the aid of heat rays, comprising a rotatable refractive polygon (2) with plane parallel surfaces (2a, 2b), the central axis (3) of the polygon (2) being inclined by a polygon inclination angle ( beta ) relative to its rotational axis (6), and the inclination angle ( beta ) being selected in dependence on the inclined setting of the plane parallel surfaces (2a, 2b) in such a manner as to provide compensation of the astigmatism in image production by the polygon. Instead of an inclined setting of the polygon, an aspherical mirror may be provided in the ray path, the mirror having a curvature so matched to the optical characteristics of the polygon as to compensate for the astigmatism (see Fig. 2 not shown). <IMAGE>

Title: Evaluating the quality of mixing in a combustion chamber
Inventor: KARAMANLIS ANTONY
IPC: G01J5/00
Filed: 1981-06-23
Abstract: To evaluate the quality of mixing of fuel and air in a combustion chamber for use in a gas turbine engine, a first fluid (unheated air) which simulates the flow of combustion air is supplied to a mixing zone 40 in a combustion chamber 16 through an inlet 38 and a swirler assembly 24, and a second fluid (preheated air) which simulates the flow of fuel, is supplied to the mixing zone 40 through a fuel feed arm 34 and a fuel injector nozzle 32 and mixes with the first fluid. The mixture is then passed through a perforate body (honeycomb catalyst 36) and the temperature distribution at the downstream end, which corresponds to the quality of mixing of the fuel and air in the mixing zone 40 of the combustion chamber 16, is measured using an infrared radiation camera and a display unit. <IMAGE>

Title: Variable compression ratio pistons
Inventor: WOODWARD HENRY EDWIN
IPC: F02B75/04
Filed: 1982-11-22
Abstract: A piston for an internal combustion engine, has a crown portion or upper end and parts (1 and 2) capable of limited relative movement defining a first or upper chamber (3) and a second or lower chamber (11). Relative movement of the parts in one direction will increase the volume of the upper chamber and decrease the volume of the lower chamber. This will increase the compression ratio. Relative movement in the other direction will have the opposite effect. A connecting rod (5) has therein an oil supply passage (4) connected to the first and second chambers by non-return valves (10 and 21 respectively) for permitting oil flow to these chambers. There is also discharge valve means for controlling oil flow from the first chamber at a first flow rate when the oil pressure in the first chamber is at a first level and a second higher discharge rate when the oil pressure in the first chamber is at a second higher level. The discharge valve means may comprises two separate discharge valves (14 and 25) or a single discharge valve (Fig. 4). The second chamber has a restricted discharge passage (12) for controlling the flow of oil therefrom. <IMAGE>

Title: Regeneration of mixed ion- exchange materials
Inventor: EMMETT JAMES RATCLIFFE
IPC: B01J49/00
Filed: 1983-02-14
Abstract: In a method of regenerating mixed ion exchange materials, the materials are classified into layers. The lower layer is then transferred from the separator vessel 10. The transfer is controlled by detecting an interface between materials, e.g. at window 100. The separated materials are then regenerated in vessels 12, 10 after which the anion material is reclassified to allow any contaminant cation material to settle to the bottom thereof. Material is then removed from the bottom of the anion layer to remove settled contaminant cation material. The removed material is isolated from the regenerated materials which are then remixed in vessel 10. The method reduces the cross- contamination of materials that occurs during the separation of classified materials and, particularly, reduces the amount of cation material in the sodium form (following regeneration of the anion material) that is eventually returned to service. <IMAGE>

IPC: H02M3/28
Filed: 1983-06-13
Abstract: A pulse power source device which can supply a pulse power output, the pulse width of which is controlled to be selectively large or small, comprises two oscillation circuits (1, 2) to one of which a timing pulse having a desired delay time is provided from a delay circuit (3) and two square-wave inverters (4, 5) respectively connected to each of the oscillation circuits (1, 2) to receive outputs from the circuits.

Title: Molecularly orientating plastics material
Inventor: MERCER FRANK BRIAN
IPC: B29D99/00
Filed: 1983-10-10
Abstract: It is known to form an integral plastics material mesh structure by punching a square or rectangular pattern of holes in a starting material sheet, and then stretching. Particularly when the material is stretched biaxially, irregularities occur across the structure. In order to avoid such irregularities, the strand-forming zones 3,7 are formed with depressions 13,14 with the sheet at ambient temperature, prior to stretching. This is found to greatly improve the regularity, as well as increasing through-put speeds and decreasing power requirements, particularly with polypropylene.

Title: Air intake equipment
Inventor: SHACKELL JOHN
IPC: B01D39/08
Filed: 1984-02-17
Abstract: Gas turbine or diesel engine air intakes for use in marine or other adverse environments, normally use a three-stage equipment for reducing moisture which has a first stage 5 of vanes for removing the bulk of the water, a second stage coalescer 8 for coalescing droplets which pass the stage 5, and a third stage of vanes 14 for removing the enlarged droplets. For other applications, two stages, namely a coalescer and a vane type separator, may be sufficient. The conventional non-woven or felted coalescer pad 8 is replaced by a woven fabric of honeycomb structure so as to ensure that the fibres of the pad are generally normal to the incident air stream, for greatest efficiency in coalescence, while at the same time maintaining substantial voidage in order to keep the pressure drop to acceptable levels. The use of two layers of an appropriate honeycomb structure material, supported in corrugated formation by wires 9, is preferred. <IMAGE>
