Title: A heat exchanger arrangement for a gas turbine engine
Inventor: JONES EMLYN
IPC: F01P11/10
Filed: 1989-08-04
Abstract: A heat exchanger arrangement for a gas turbine engine (10) suitable for cooling an accessory gearbox or generator comprises a first duct (32) which supplies cooling air to a heat exchanger (34) and a second duct (36) which supplies the cooling air from the heat exchanger (34) to an exit nozzle (38). A line joining the mid points of the first duct (32) is arranged at an angle of approximately 20 DEG  with respect to the inlet end face of the heat exchanger (34). The first duct (32) is arranged to diffuse the airflow sufficient to reduce the flow velocity to such an extent that the effects of compressibility are not significant, to minimise losses due to turning the cooling air through a bend formed where the first duct (32) joins the heat exchanger (34). The turning of the cooling air provides additional diffusion of that air. The heat exchanger arrangement allows the heat exchanger arrangement to be accommodated in relatively small spaces, or larger heat exchanger arrangements to fit in an existing space. <IMAGE>

Patent GB-897860-A (GB)
Abstract: 897,860. Resistors. SOC. ELETTROTECNICA CHIMICA ITALIANA S.p.A., and CANEGALLO, G. March 5, 1959 [March 7, 1958], No. 7753/59. Class 37. A resistor is protected by inserting it into a glass tube and collapsing the tube on to the resistor by simultaneous heating and partial evacuation. Fig. 1 shows a cylindrical resistor R contained in a glass tube T the ends of which are connected to a vacuum pump. The tube T is gradually drawn through an annular heater N so that the action of heat and atmospheric pressure collapses the glass tube on to the resistor R as shown in Fig. 4. The surplus glass tube beyond lines L1, L2 is then removed. The resistor may consist of a former carrying a coating of graphite, metal or metal oxide, connected to end caps T. It may be protected by an intermediate layer of granular material such as silica, magnesium oxide, kaolin or asbestos suspended in a solution of gum arabic in water or natural or synthetic resin in turpentine. The intermediate coating is applied by dipping, spraying or brushing. The resistor is then finally coated with glass as described. Reference is made to the use of the invention with composition resistors comprising kaolin, clay, glaze, various silicates mixed with powders of electrically conductive materials such as metals, graphite, lamp black, or metal oxides, baked or sintered together. Reference is also made to resistors of wire wound on cores of asbestos or glass fibre. The outer glass coating may include granular materials such as silica, magnesium oxide or metal powder in order to increase the heat conductivity.

Title: Thermal-radiation detection systems and optical choppers
Inventor: TURNBULL ANDREW ALFRED
IPC: H04N5/225
Filed: 1990-01-03
Abstract: A thermal-radiation detection system comprises infrared detector elements arranged in rows and columns in a 2-dimensional array ABCD. A rotatable optical chopper 20 in front of the array ABCD periodically chops the transmission of thermal radiation to the detector elements. In accordance with the invention the segments 21 and 22 of the chopper have non-radial leading and trailing edges 23 and 25 so proportioned in relation to the array ABCD that, as the rotating segments 21 and 22 pass in front of the array, successive portions of each edge 23 and 25 become substantially aligned with a plurality (e.g. 30% or more) of detector elements in each successive row (e.g. AB or CD). A symmetrical design is formed with these edges 23 and 25 as arcs of circles which are centred at intervals 01 to 08 around the circumference of a primary circle centred on the axis of rotation 0 of the chopper 20. The circles can be so arranged as to have substantially the same alignment errors with the first row AB as with the last row CD, and phase errors between the chopping of radiation and the electronic sampling of the detector elements in the rows can be small. <IMAGE>

Title: Coin validator with impact sensor
Inventor: FURNEAUX DAVID MICHAEL
IPC: G07D5/04
Filed: 1990-09-24
Abstract: A coin is inserted in a coin entry 1 and caused to fall under gravity on to an energy-absorbing element 3. The impact of the coin on the element is sensed by a piezoelectric sensor 4 and coins are discriminated between on the basis of whether the gradient of at least a pan of the signal from sensor 4 meets an acceptability criterion. Preferably the output of the sensor is fed through a high-pass filter 11 to a differentiating circuit 12, the differentiated output being compared with a predetermined threshold value and, if greater, an output signal being generated. This signal, optionally together with a coin presence signal from coils 6, is supplied to circuitry 15, 16, 17, 19, 20, 21 for causing an output inhibit signal I to drop to a low level. The signal I is applied to an inhibit terminal 18a associated with a validation circuit 7 for causing, in the case of a coin deemed to be acceptable, an acceptance gate 8 to be opened by a solenoid 9. The inductive coils 6 also serve to determine whether a coin being tested is of a desired denomination. The acceptability signal is generated only if the coin passes through the region of the coils within a predetermined interval and if there is not already a coin in the region when a coin hits the element 3. Lid 10 may be pivoted open to release jammed coins. <IMAGE>

Title: Data collecting apparatus
Inventor: IKOMA TADASHI
IPC: H04M11/00
Filed: 1991-01-29
Abstract: An apparatus 100 for collecting data associated with the operations of various equipment eg a photocopier 201, sheet feeder 202 and collator 203 over telephone lines and sending the collected data to a central processing station, e.g. a host computer. The apparatus is connectable even to conventional image forming equipment or similar equipment which lacks a dedicated connector for outputting data to the apparatus. A data signal outputted by the photocopier 201 is fed to the apparatus 100. The apparatus discriminates data meant therefor and data meant for a peripheral unit 202, 203 cooperative with the equipment. The data meant for the peripheral unit is sent to the peripheral unit while the data meant for the apparatus is stored in a memory built therein and sent out to a telephone line 320. Further, a data signal from the photocopier may be split into data meant for the peripheral unit and data meant for the apparatus beforehand, in which case the former is directly sent to the peripheral unit and the latter is sent to the telephone line while being stored in the memory. When a failure of the nature preventing a service call from being automatically sent occurs in the equipment, an emergency call (service call) is sent to the host computer as data via the apparatus. <IMAGE>
