Title: Measuring deflection of golf club shafts as aid to training
Inventor: HANDLEY JOHN
IPC: A63B69/36
Filed: 1982-06-26
Abstract: One or more strain gauges (4, 5) are attached to the shaft of a golf club and connected to additional resistances (20, 21) to form a Wheatstone bridge so that the rate of acceleration will be indicated by the voltage across the bridge when the club is swung, deflecting the shaft. This voltage is amplified at (27) and used to operate a two tone buzzer (33) which will sound one tone when the rate of acceleration preferred by the player is obtained and another tone when this rate of acceleration is exceeded. These tones are generated in dependence on whether the amplified voltage exceeds thresholds set for one or both of comparators (28, 29). Three variable resistors are used:- (32) to ensure that the voltage across the bridge is zero when no bending force is applied, (30) to give one tone when the desired force is applied and (31) to give another tone when the desired force is exceeded. These resistors can be duplicated and either set selected by means of a switch so that the circuit can be used with two types of club. <IMAGE>

Title: Stator core for a dynamoelectric machine
Inventor: FRICKE ROGER FREDERICK
IPC: H02K15/02
Filed: 1982-10-26
Abstract: A dynamoelectric machine having a laminated core 10 comprises a plurality of annular laminations 12. Each lamination is edge rolled from straight strips of magnetic material with teeth 14 punched into one edge. Each lamination is slightly less than 360 DEG  in arcuate length, leaving a slight gap 18 between its ends to allow the finished core to be accurately sized by compressing its outer surface. By punching the straight strips from sheet metal in such a way as to orient the grain structure in the direction of tooth extension and edge rolling the opposite edge, a selective grain orientation can be achieved which is magnetically advantageous throughout the core. <IMAGE>

Title: Sorting living spermatozoa
Inventor: DRESSER DAVID WILSON
IPC: A61K35/52
Filed: 1983-04-27
Abstract: In a method for sorting spermatozoa, spermatozoa are stained with a fluorochrome dye. The fluorescence distribution of stained spermatozoa is complex: non-motile spermatozoa display a higher fluorescence than motile spermatozoa. The fluorescence profile of the motile spermatozoa is bimodal, and enables the spermatozoa to be sorted into distinct populations of motile spermatozoa.

Title: Fire detector
Inventor: DUGGAN JACK
IPC: H01H37/76
Filed: 1983-09-22
Abstract: In a fire detector of the type disclosed in specification GB 2060261, the closure cap covering at least the vent aperture (30) extending through the base from the space (26) between the diaphragm (22) and base, to the back of the detector has a depending skirt (37A) which extends to a position just above the bottom (35A) of the endless wall (35) of the vent aperture (30) whereby air is drawn into the vent aperture (30) substantially only from the space between the endless wall (35) and skirt (37A) under normal contraction of the ambient atmosphere between the diaphragm and base, thereby precluding entry of dust and other contaminants. The fin (14) is connected to the ferrule (16) by causing circumferentially equally spaced peripheral portions of the end of the ferrule proximate the central aperture of the fin through which the ferrule is inserted to be forced to flow radially over portions of the fin. The side wall of the ferrule (16) may also be tapered at about 5 DEG  to the vertical. <IMAGE>

Title: Measuring speed and/or length of elongate material
Inventor: KYRIAKIS JOHN
IPC: G01P3/50
Filed: 1984-02-06
Abstract: The speed and/or length of an elongate material 4 is measured from the corresponding speed and/or movement of one of a pair of belts 2 and 6 between the facing runs of which the material 4 passes. The belts are driven by friction with the elongate material, and errors due to slippage are kept to a minimum due to the extended contact of the belts with the material over the length of the runs. When the belts are supported by pulleys 3 and 5, the speed and/or length of the material is measured by an encoder 7 responsive to the rotation of the pulley 3. The runs of the belts are preferably horizontal and when used in conjunction with the manufacture of the elongate material, are preferably aligned with the exit of the material from the manufacturing apparatus. <IMAGE>

Title: A method and plant for cooling gases and removing dust from them
Inventor: HAMMARSKOG BJORN
IPC: B01D51/00
Filed: 1985-02-28
Abstract: The invention relates to a method and a plant for cooling gases and removing dust from them. In a first step after saturation with water vapour, the gas is brought to accelerate, additional water being simultaneously added to the dust particles in the gas, whereupon the gas flow thus loaded is brought to pass over the surface of the water in a first sedimentation container (1) so that the majority of the dust content is released to the sump in the sedimentation container (1). The gas flow is thereafter subjected to final cleaning and cooling in a second step, through direct contact with water, whereupon the water utilized in this manner, possibly via a second sedimentation container (2), is wholly or partially returned to the first step.

Title: A multi-microprocessor system with confederate processors
Inventor: JAYARAM NARAYANASWAMY D
IPC: G06F15/173
Filed: 1986-07-05
Abstract: A multi-microprocessor architecture with hardware mechanisms and message paths that can effectively map the software mechanisms of synchronization and interprocessor Communication primitives (shared variable and message-based), has been presented. It is claimed that this design could reduce the memory conflicts arising from busy-wait synchronization, and enables interrupts to be used as signals in the operations of synchronization and interprocessor Communication primitives. A confederate processor (COP) is operative for generating interprocessor interrupts and sets up interface logic of computer modules for broadcasting messages. Each computer module has locations in all mailbox memories (MM) for messages, task state information and shared variables. <IMAGE>
