Title: Tricone roller bit seal - with O-ring on conical seat urging L-section sealing ring against roller shoulder
IPC: F16J15/34
Filed: 1973-09-24
Abstract: A tricone roller bit has cutter rollers supported in a bearing, with a sealing ring around the spindle. The sealing ring (plastics or metal) has an inner contoured face and an outer sealing face. An O-ring (rubber) acts on the contoured face and urges the sealing face against a sealing shoulder of the outer roller. This requires less space in an axial direction so that more space is left for a stronger bearing. The seal acts also as a safety release valve.

Title: Logic signal controlled frequency modulator - signals are applied to variable oscillator through digital analogue converter
IPC: H04L27/12
Filed: 1973-11-07
Abstract: Logic signals, binary, bipolar or possibly other forms, provide control of frequency excursions to one part in 106. A variable output oscillator working at about 28GHz is controlled by a variable capacitance diode and feeds a modulator also accepting a high stability frequency input. Its output is fed via a variable bandpass filter to a frequency divider providing three division rates, the rate being determined by logic signal inputs. A phase discriminator follows and feeds, via a low pass filter, an analogue-digital converter circuit completing the feedback loop to the main oscillator.

Title: Method of securing female element to shaft - involves deforming element into opposed recesses on shaft
IPC: F16B17/00
Filed: 1974-03-26
Abstract: A method of attaching a female head to a shaft without using a transverse pin is described, since the shaft is not drilled to take a pin, its strength is maintained.
