Inventor: GOODWIN GEORGE
IPC: B60K17/26
Filed: 1990-01-10
Abstract: A power transmission unit for coupling a prime mover to a vehicle, in particular a bicycle has a clutch means (40), a gear train (10), and a freewheel means (17). The output shaft of the prime mover is connected to the input side (40a) of the clutch means (40). The output of the clutch means (40b) is connected to the input side (21) of the gear train (10). The output side (24) of the gear train is connected to the freewheel means (17). The freewheel means (17) is connected to a sprocket wheel. The sprocket wheel together with another sprocket wheel is mounted on a common freewheel which in turn is mounted on the crankshaft of the bicycle. The other sprocket wheel is connected to the rear wheel of the bicycle. In the absence of power from the prime mover, the bicycle may be used in a conventional manner. When in use, the prime mover drives the rear wheel of the bicycle via the clutch (40), gear train (10), freewheel means (17), sprocket wheels and the rear wheel.

Title: Musical interval training device
Inventor: OGBORNE JOHN
IPC: G09B15/04
Filed: 1990-02-15
Abstract: A portable, battery-operated device is intended for use by music students for the purpose of improving the recognition of musical intervals. The device is housed in a plastic case 1 with a number of buttons and indicators on the front. In use, the student requests from the device a random interval 7, after which he may sound the two tones separately or consonantly, 4, 5. Once the student has decided on the value of the interval he selects the appropriate answer 2, a correct choice illuminating the appropriate button. An incorrect answer will not illuminate a button and the student may try again or request the answer 6. A new interval may then be requested 7. The random intervals are limited by selecting a grade 3 and the selection may be simplified by fixing the low note to middle C. The block diagram for such a device is described and illustrated. <IMAGE>

Title: Neural network employing levelled summing scheme with blocked array
Inventor: PARK CHIN S
IPC: G06V30/194
Filed: 1990-03-02
Abstract: A neural network is subdivided into a plurality of smaller blocks 15. Each block comprises an array of pattern matching cells 14 which is used for calculating the relative match, or Hamming distance, between an input pattern and a stored weight pattern. The cells are arranged in columns along one or more local summing lines L00, L10, L20. The total current flowing along the local summing lines for a given block corresponds to the match for that block. The blocks are coupled together using a plurality of global summing lines G0, G1, G2. The global summing lines sum the individual current contributions from the local summing lines of each associated block. Coupling between the local column lines and the global summing lines is achieved by using a specialized coupling device 12 which permits control of the coupling ratio between the lines. By selectively turning on or off various blocks a measure of the match for individual blocks or for groups of blocks representing a subset of the network, may be calculated. Control over the coupling ratio within the blocks also prevents destructive levels of current from building up on the global summing lines.

Title: Strap for holding a key
Inventor: LEWIS ROGER CHARLES
IPC: A44C5/00
Filed: 1990-03-06
Abstract: A strap (10) carries a key (12), and is used to secure the key to part of a user's body such as a wrist. The key (12) has a shank (52) and a head (50) with a slot (54) through which the strap passes. The key head is slidable but captive on a portion (10a) of the strap between a thickened portion (34) and a stop (56). The thickened portion (34) is formed with a recess (36) for receiving a shank when the strap is worn. When the strap is worn, for example on the user's wrist, the head of the key is located between the strap and the user's wrist, whereby the shank of the key is retained in the recess and is shielded to prevent it from causing damage or injury. The side walls of the recess (36) diverge away from the entrance (38) to maintain the strap's flexibility when the key is in the recess. <IMAGE>
Patent GB-2234554-A (GB)
Title: Hermetic compressor with rotary rolling piston
Inventor: DA COSTA CAIO MARIO FRANCO NET
IPC: F04C29/02
Filed: 1990-06-18
Abstract: The rolling piston 5 is of annular section and rolls around a crankshaft 6 within a cylindrical chamber of a cylinder block 4. The piston 5 acts in combination with a sliding vane 9 to separate the cylindrical chamber into suction and discharge regions, having lower internal pressures than the oil elsewhere inside the shell 1 of the compressor during most of the cycle of rotation of the piston 5. Consequently, oil passes through small gaps between the annular end-faces of the piston 5 and the end walls of the cylindrical chamber to lubricate and seal components of the compressor. By providing a rolling piston with a high ratio of external to internal diameter (>/=1.63), the radial path of the lubricating oil is increased. In this way the flow of lubricating oil is reduced, without the disadvantage of the conventional method of reducing oil flow, in which the annular faces are moved closer to the end walls of the chamber resulting in increased friction. <IMAGE>

Title: A process for the manufacture of a web of spun fibres of thermoplastic synthetic material
Inventor: BALK HERMANN
IPC: D04H3/147
Filed: 1990-08-20
Abstract: A process for the production of a web of spun fibres of thermoplastic synthetic material, has the thermoplasticized synthetic material supplied to a nozzle head with at least one spinneret into which it enters as an extrusion of at least two layers that consist of chemically and/or physically different thermoplasticized synthetic materials and in which the extrusion is blown apart by hot or cold air to form spun fibres.

There may be a plurality of aligned spinnerets of circular-shaped nozzle section, which share out the extrusion of different materials. At least one wide slot spinneret may be used and the thickness of the spun fibres can be controlled by the gap width of the slot. A spinnerette or spinnerettes may be used, the inner wall of their nozzles having a saw-tooth profile.
