Title: Hair curling implement
Inventor: THALER ARNOLD
IPC: A45D1/04
Filed: 1985-09-18
Abstract: A hair curling implement constructed with a high efficiency heating system and a soft outer surface for contact with the hair. The hair curling implement, i.e., the heated curling iron and heated curling brush has an elongated tubular member around which hair of the user can be wrapped and a handle that is coupled to the elongated member. A flat resistance heating wire is wrapped in a spiral pattern around the elongated tubular member and an electrically non-conductive sleeve is positioned over and in contact with the flat resistance heating wire on the elongated member. Heat generated by the heating element is readily transferred to the hair without the flat resistance heating element coming into contact with the hair. <IMAGE>

Title: Improvements in fishing rods
Inventor: ECCLES THOMAS
IPC: A01K87/00
Filed: 1985-09-25
Abstract: A fishing rod of the type which is hollow from its tip to a point adjacent which, in use, the reel will initially discharge the line; in which the line, instead of passing through the conventional succession of eyes along the outer surface of the rod, enters the hollow rod at or adjacent the said point and runs up the inside of the rod to merge at or adjacent the tip thereof; the rod being stepped, in the region 16 where the reel is to be fixed in use, so that the line as it discharges initially from the reel runs straight into the hollow rod rather than bearing against the surface of the hollow interior of the rod in frictional engagement therewith, which further comprises, a tip region at which the line emerges from the inside of the rod which is appropriately reinforced (or is already inherently made of suitably wear resistant material); the tip region being bell mouthed so as to minimise the tendency of the line to wear the edge of the rod in repeated use.

Patent GB-2171559-A (GB)
Title: Operating apparatus for a switch
Inventor: NAKAHATA MINORU
IPC: H01H3/30
Filed: 1986-02-18
Abstract: An operating apparatus for a switch has a rotatably supported driven shaft 28, a driven plate 33 secured to the driven shaft, and a drive plate 29 which is rotatably mounted on the driven shaft. Spring 31 is disposed between the drive plate 29 and the driven plate 33 in such a manner that the rotation of the drive plate 29 causes the spring 31 to store energy and to exert a torque on the driven plate 33 in the direction of rotation of the drive plate 29. The driven plate 33 is prevented from rotating when the drive plate 29 is rotated by one of a first pair of latches 37a, 37b which latches the driven plate 33 and by one of a second pair of latches 41a, 41b which latches the first latch and maintains the engagement between the first latch and the driven plate 33. The portion of the first latch which engages the driven plate 33 is so shaped that the direction of the torque applied to the first latch by the driven plate 33 is the same as the direction of the torque applied to the driven plate 33 by the spring 31. The operating apparatus may also comprise a latching mechanism 50a, 50b for maintaining the spring 31 in a state in which it stores energy even when no drive force is applied to the drive plate 29, the switch being subsequently actuated by releasing the second latch 41 by a remote control device to cause rotation of the driven shaft 28 and actuation of switch contacts. The second latch 41 may alternatively be released by a release member on the drive plate 29. <IMAGE>

Title: Apparatus for measuring shaft torsion
Inventor: HUTCHINSON ANDREW WALTER
IPC: G01P3/489
Filed: 1987-07-22
Abstract: A sensor arrangement 11, 12, 14 responsive to relative angular positions of two locations on a shaft 10 to provide, on a line 17, filtered pulses whose frequency are proportional to speed and torsion respectively of the shaft 10. A counter 21 is responsive to the pulses on line 17 and to a reference frequency from a clock 20 to provide a count value corresponding to the product of torsion and time. A counter 22 is responsive to the reference frequency to provide a time count value. Cyclically recurring pulses on line 17 e.g. once per shaft revolution as determined by a counter 18 and output over a line 31 cause registers 24, 25 to store the most recent cumulative values from the counter 21, 22 respectively. When it calculates shaft torsion, a control means 27 reads the register values and resets registers and counters. In a similar arrangement, the counter 18 and its associated register 23 are responsive to the pulses on line 17 to provide values corresponding to speed of the shaft 10. <IMAGE>
