Title: Method for checking the friction between the traction sheave and the suspension ropes of an elevator
Inventor: VANHALA TIMO
IPC: B66B5/00
Filed: 1989-04-03
Abstract: In a method for checking and monitoring the friction between the traction sheave and the suspension ropes of an elevator, the slippage between the traction sheave and the suspension ropes of the elevator is measured, the elevator comprising an elevator machine, a hoistway and an elevator car and a counterweight moving in the hoistway. The rope slippage is measured either periodically by performing test drives or continuously by means of an impulse device placed in the elevator machine and measuring the motion of the tractin sheave, an impulse device monitoring the movement of the elevator car and an impulse device monitoring the load in the car. The data provided by these impulse devices is transmitted to a computer which calculates and monitors the relative slippage between the traction sheave and the suspension ropes of the elevator.

Title: Reservation systems
Inventor: EDDISON SIMON PETER
IPC: G06Q10/00
Filed: 1989-06-13
Abstract: A reservation system for an amusement park ride has a number of reservation stations 4 positioned around the amusement park. Customers entering the amusement park are provided each with an electronic card, which can be inserted into any of the reservation stations 4. Then, using a key pad 17, the customer requests a reservation for a particular ride. The reservation system maintains a count of existing reservations, and calculates the expected time taken for these existing reservations to be taken up. As a result of this calculation, the system offers the customer an earliest reservation time for the ride. The customer may then either accept that time or request a later time. Preferably, the electronic cards include means to display reservation times for various rides and or timers/indicators to indicate when a reservation time is approaching.   In use of the system, queueing time at various rides may be reduced, thereby increasing the enjoyment of the customers and the potential revenue of the amusement park operators. <IMAGE>

Title: Support arrangement for nozzle guide vane
Inventor: HAYTON PAUL ROBERT
IPC: F01D5/30
Filed: 1989-07-06
Abstract: In a gas turbine engine having a ceramic nozzle guide vane 18 supported by a metal turbine casing 28, 29 the radially outer end portion 23 of the vane is provided with a support arrangement comprising opposed frustoconical sections 26, 27 which converge towards each other onto a middle cylindrical section 25. The support arrangement also includes a metal split ring 30 which surrounds the cylindrical section 25, and the ends of the ring abut the frustoconical sections. The split ring may be provided with a flange 35 which cooperates with a groove structure on the turbine casing, thus enclosing the split ring to the casing. A locking insert 38 then fastens together two sections 28, 29 of the casing either side of the vane, thereby holding the split ring 30 against the vane. On increase in temperature the split ring expands more than does the portion 23. The ends of the split ring therefore slide against the frustoconical surfaces of the portion 23 to take up the expansion, and in so doing maintain contact with the vane. Seals 39, 40, 46 may be provided. The support arrangement could be applied to structures other than gas turbine engines. <IMAGE>

Patent GB-904713-A (GB)
Abstract: 904,713. Feeding webs. BRITISH INSULATED CALLENDERS CABLES Ltd. March 11, 1960 [March 12, 1959], No. 8618/59. Class 100 (1). [Also in Group XXV] The tension of tape to be wound on a core, for example an electric cable conductor, is controlled by imparting a retarding force to the tape followed by an advancing force. Pads 18 of oiled felt rest on a disc 20 rotating with a supply pad 1 of tape, the pressure of the pads being adjusted by spring-urged levers 13 the position of which is dependent on the tension in the tape leaving the pad 1 as detected by a roller 6 to impose on the tape a tension in excess of that desired when wound on the conductor 2. From the roller 6 the tape passes over a guide roller 21 to an overfeed device comprising rollers 28, 29, a capstan 25 rotating with peripheral speed three times that of the tape and a skewed roller 27. The tape is so passed around these rollers as to have a total angle of wrap of between 60 and 320 degrees in two passes over the capstan 25, the angle being varied by adjusting the position of the rollers 28, 29 by means of a screwed shaft 31 moving a plate 30. On leaving the roller 29 the tape has the desired tension due to the " feeding " action of the capstan 25. Instead of a capstan an endless belt may be provided.

Title: Resolving clashes in a data communications system
Inventor: HOULT NIGEL SHERIDEN
IPC: H04L12/413
Filed: 1991-12-03
Abstract: A data communications system, e.g. for "hands free" personnel location or access control, comprises a master transceiver (M) and a plurality of slave transceivers (A, B) for transmitting individual identification messages (e.g. 1010, 1001) to the master in accordance with a code (e.g. Manchester II) in which binary values are represented e.g. by an infra-red transmission occurring during a first portion or a second portion of a bit period respectively. The master alternately echoes back to the slaves a binary value corresponding to the value last received. In the event of a clash, however, i.e. different values transmitted from different slaves during the same bit period, the master echoes back only a predetermined single value and the slave(s) which did not transmit that value then cease transmission. This process continues until one of the slaves has transmitted and had echoed back bit-by-bit the whole of its message. That slave then ceases transmission and the remaining slaves recommence until by repetition of the process all of the individual slave messages have been transmitted and echoed back. <IMAGE>

Title: Electroluminescent silicon device
Inventor: CANHAM LEIGH TREVOR
IPC: H01L21/306
Filed: 1993-08-19
Abstract: An electroluminescent silicon device (10) includes a silicon structure (12) which comprises a bulk silicon layer (14) and a porous silicon layer (16). The porous layer (16) has merged pores (20) which define silicon quantum wires (18). The quantum wires (18) have a surface passivation layer (22). The porous layer (16) exhibits photoluminescence under ultra-violet irradiation. The porous layer (16) is pervaded by a conductive material such as an electrolyte (24) or a metal (48). The conductive material (24) ensures that an electrically continuous current path extends through the porous layer (16); it does not degrade the quantum wire surface passivation (22) sufficiently to render the quantum wires (18) non-luminescent, and it injects minority carriers into the quantum wires. An electrode (26) contacts the conductive material (24) and the bulk silicon layer has an Ohmic contact (28). When biased the electrode (26) is the anode and the silicon structure (12) is the cathode. Electroluminescence is then observed in the visible region of the spectrum.
