Title: Yarn bobbin - is of a cast aluminium alloy blank turned to the accurate dimensions and age hardened or covered with a hard surface coating
Inventor: SCHLOTTER RICHARD
IPC: B65H75/50
Filed: 1992-11-26
Abstract: To produce a light metal yarn bobbin with a hollow shaft and projecting side flanges, the bobbin blank is cast from a high quality aluminium alloy with a strength of 100-140 F, and the blank is turned to give the accurate dimensions. The bobbin is age hardened to increase the surface hardness. The bobbin blank is produced by centrifugal casting, and is tempered by the application of a hard coating, by electro-plating to give a chrome coating. Alternatively, chemically reactive material can be applied to the aluminium alloy surface for conversion of the surface into a hard layer. The aluminium surface can be covered by diffusion coating, or by immersion in a molten bath. The aluminium alloy surface can also be coated with a hard compound material as a metal or alloy, or it can be covered by an enamel coating. The bobbin is, additionally, thermally age hardened. USE/ADVANTAGE - The bobbin is for yarn winding, in a textile machine, which can be rotated at high speeds. The bobbin prodn. is within acceptable mfg. costs, with the required strength performance, and accurate dimensions to give true running at high rotary speeds.

Title: Mains supply current frequency detector - has mains transformer coupled to period detector, and counts frequency of occurrence of period detection signal in set time
Inventor: KIM JONG ROK
IPC: G01R23/00
Filed: 1993-02-22
Abstract: The frequency detector includes a mains transformer which converts a mains alternating current into an operating voltage for the supplied equipment.  A period detector unit shapes an output waveform from the mains transformer and produces a period detection signal in each period of the shaped waveform. The frequency of generation of the period detection signal during a defined time period is counted by a further unit which also discriminates or distinguishes the frequency of the supplied mains current on the basis of the counted frequency number. USE - For detecting frequency supplied to electronic or electrical device during start-up phase after connecting supply to enable device to be switched to appropriate operating frequency, e.g. 50 or 60 Hz.

IPC: B60R21/215
Filed: 1993-02-27
Abstract: A cover is described for the aperture of a chamber accommodating an air bag 3 in the region of the dashboard 1 of a motor vehicle. The cover 2 is composed of a frame part 8 and a lid 9. The frame part 8 is releasably connected to the dashboard 1, but their surfaces bear firmly against one another. The lid 9 is articulated to the frame part 8 by means of metal tapes 11 and is otherwise connected via predetermined breaking points 13 to the frame part 8. When the air bag 3 is activated, the lid 9 is pressed out of the frame part 8. The lid 9 is unable to damage the dashboard 1 during opening. Only the frame part 8 is impaired by the lid 9 as it opens. The frame part 8 may, however, be easily removed from the dashboard 1 and replaced by a new cover 2. This brings about a considerable reduction in repair costs after activation of an air bag. <IMAGE>

Title: IC engine exhaust air=fuel ratio sensor with oxygen concn. cell solid electrolyte and pump - controls supply of heater power on condition that pump current is interrupted and removes condition after period of time period after supply of power.
Inventor: SUZUKI HIROYOSHI
IPC: G01N27/406
Filed: 1993-06-25
Abstract: The oxygen concn. cell and pump elements (11b, 11c) consist of solid electrolyte conducting oxygen ions, and are respectively provided with an electrode. The sensor (1) also has a heater (12) for heating the two elements (11a, 11b), a pump control unit for the current flowing in the pump element, so that the voltage of the cell element assumes a predetermined value. A pump current evaluation unit determines the pump current. A pump switch-off unit interrupts the supply of pump current. A supply unit delivers power to the heater, and first and second timers control the interruption of the pump current. A control unit activates the supply of power by the power supply unit to the heater, if the pump current is interrupted. It also curtails the interruption of the pump current, during a predetermined time duration in predetermined intervals. This results after the activation of the power supply to the heater with the help of the first timer. USE/ADVANTAGE - IC engine. Determines activation point of sensor with increased precision, without causing any deterioration of sensor characteristics. It can determine anomalies of sensor. Does not require additional components for determining of cell and pump voltage.
