Title: Means for securing a bearing to a shaft
Inventor: MARTINIE HOWARD M
IPC: F16C35/063
Filed: 1985-08-10
Granted: 1989-03-14
Abstract: An inner bearing race extends around a shaft (37) and has a raceway (32) for receiving other bearing elements.  Set screws (72) threadedly engage extensions (68) of the inner race, to contact the shaft.  Force applied by the screws deflects the extensions into contact with the shaft.  Selectively placed grooves (74) are located between the screws and the raceway to absorb forces placed on the extensions to prevent or minimise distortion of the raceway.

Title: Water-swellable clay composition
Inventor: ALEXANDER WILLIAM
IPC: C09K17/42
Filed: 1985-08-13
Granted: 1993-08-26
Abstract: A water-swellable clay composition, comprises a water-swellable clay, particularly a montmorillonite clay, such as bentonite; xanthan gum; and one or more additional water-soluble gums, for example, guar, dextran, acacia or locust bean. The xanthan gum together with one or more additional water-soluble gums prevents the montmorillonite clay from substantial coagulation or flocculation upon contact with salt contaminated water even in high concentrations of, for example, 15-40% by weight salt. Xanthan gum is an amount of 0.1-20% based on the weight of the water-swellable clay, in the composition together with one other water-soluble gum, for example guar gum, dextran gum, acacia gum and/or locust bean gum in an amount of 1.O-10% based on the weight of bentonite in the composition, will provide a clay composition capable of excellent stability without component separation in salt contaminated water. The composition is particularly useful as an additive to compositions used as stable drilling fluids in rotary drilling, and as lagoon and landfill sealants.

Title: Blades for propeller fan
Inventor: TAKIGAWA KAZUNORI
IPC: F04D29/66
Filed: 1987-03-21
Granted: 1990-10-06
Abstract: If at least a portion of the suction side surface of each blade is coarsened, the air in the boundary layer is agitated, so producing a finely divided swirling flow of air which mixed with the outer layer so imparting considerable kinetic energy to the boundary layer. This reduces the thickness of the boundary layer and prevents or at least delays its separation. The degree of which the boundary layer is agitated by the coarsened surface depends on the density and depth of the indentations defining the coarsened surface and the velocity of the air. The velocity of the air at any partic. point on each rotating blade is proportional to its radial distance from the centre of the fan toward the radially outer end of the blade.

Abstract: A frequency synthesizer which uses a direct digital synthesizer (DDS) to generate a highly accurate periodic signal of a frequency selected from a plurality of reference frequencies. The DDS output signal is bandpass filtered and amplitude limited to reduce spurious noise. In one embodiment, the DDS frequency synthesizer is coupled to a phase lock loop which receives the DDS generated reference signal and a divide-by-N signal for generating an output signal at a frequency determined by the divide-by-N signal. The frequency resolution of the phase lock loop is N times the reference signal. In a second embodiment, the DDS is incorporated within the feedback path of the phase lock loop. An input reference frequency signal is provided to the phase lock loop with the DDS clock signal provided as a function of the phase lock loop output frequency. The DDS receives an input frequency control signal which determines the DDS step size. The synthesizer output frequency is a function of the input reference frequency, the number of bits in the digital word of the frequency control signal and the DDS step size as determined by the frequency control signal. Optional dividers may be provided in the feedback path which may further affect the synthesizer output frequency.

Abstract: 텔레비전 수상기에서. 오디오 증폭기(48,50)에서 확성기(40,42)에 인가된 전압은 저역 통과 필터되어 임계 검출기(52)에 결합된다. 검출기가 트립되지 않도록 정상 오디오는 감쇠되나. 정상 DC는 필터 통과되어 검출기를 트립한다. 검출기(50) 출력은 수상기를 오프케 작용하는 수상기의 X-선 보호 회로(26,60,62)에 결합된다.
