Patent GB-2125305-A (GB)
Title: Yo-yo with twist-resistant support
Inventor: MACCARTHY PATRICK
IPC: A63H1/30
Filed: 1981-09-21
Abstract: A toy capable of combined rotational and translational motion. Two parallel discs (3) are connected through their centers by a single axle (2). The axle is suspended from a support (35) connected at a position between the two discs. Said support (35) is of a twist-resistant type, offering a greater torsional resistance to twisting about the axis of the string than conventional yo-yo strings. The support (35) may be anchored to the axle (2) in a non-sleeping mode, or it may be looped around the axle (2) allowing the yo-yo to sleep. In order to operate the toy, the end of the support (35) opposite that which is connected to the yo-yo axle (2) is held by the user, and an up-and-down gentle motion is imparted to the toy. The end of the support (35) may be connected to a swivel system (40) which is in turn connected to a ring (41) for holding the toy.

Title: Clarification of xanthan gum solutions
Inventor: SYMES K C
IPC: C12P19/06
Filed: 1982-10-15
Abstract: A process for improving the clarity and filterability of xanthan gum solution comprises:   a) treating a crude xanthan gum solution at a pH of 2 to 7 with an effective amount of an acid or neutral protease, and then   b) raising the pH to 8-13 and, optionally,   c) then lowering the pH to 6-7.   The disadvantages involved in the use of crude xanthan gum broths, containing non viable microbial cells, in applications such as food formulation or enhanced oil recovery processes are overcome by the present process.

Title: Steering column lock
Inventor: MASAKI MIKIO
IPC: B60R25/02
Filed: 1983-04-12
Abstract: The lock includes a check lever 13 axially movable upon rotation of a key-actuated cylinder 3 into locking engagement with a locking rod 11 to lift the latter clear of engagement with a steering shaft (not shown). When the key-actuated cylinder 3 is turned back and the key 4 is pulled out, the check lever 13 is pulled back out of locking engagement with the locking rod 11 which then locks the steering. shaft As the check lever 13 is thus retracted, it depresses a control member 17 into a key slot 3b in the key-actuated cylinder 3. When the check lever 13 is fully moved back, the control member 17 moves out of the key slot 3b. Thus, the key 4 can be inserted smoothly into the key slot for releasing the steering lock. <IMAGE>

As shown, rear wheels (12) run up curved inclines on ramps (16) - the front ramps (20) have straight inclines and are set inwardly of front wheels (14) for engagement with slanting forward ends (22) of chassis (10). A pulley system utilising e.g. pulley wheels (44, 46, 50) and ropes or cables (57) ensures lifting of rear wheels (12) before front wheels (14); a simpler pulley system is disclosed and such system can be dispensed with, - rods (40) extruding rearwardly from bumper (26) being directly connected to link bar (56). As shown, cable (59) also operates brake pedal (60) to operate conventional brake system initially before the ramps, (16) and thereafter ramps (20). <IMAGE>

Title: Method and apparatus for detecting wear of a rotatable bit
Inventor: DAVIS ALBERT P
IPC: E21B10/22
Filed: 1985-02-19
Abstract: A method and apparatus for detecting wear of a rotatable bit used to drill a wellbore are disclosed. In drilling operations, a drilling fluid is pumped down through a drill stem and is discharged through ports (14) in the drill bit (12) and into the annulus between the drill stem and the wellbore. Excessive wear of the bit (12) at a selected location is detected by a sensor (24) which is linked (28) to a restrictive device (30) capable of reducing the flow of drilling fluid through at least one port (14). To detect excessive wear of the bit (12), at least one abradable sensor (24) is located in the bit (12) at a selected location. As the drill bit (12) wears at that location, the sensor (24) abrades until finally it is activated. Activation of the sensor (24) is transmitted by a communication device such as a wire (28) or hydraulic fluid to manipulate the restricting device (30). More than one sensor may be simultaneously linked to the restricting device with communication devices to detect wear of the drill bit at differing locations. <IMAGE>
