Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

Abstract: A dental bite block is provided. The dental bite block includes a body having a first end and a second end, an outer sidewall, and an inner sidewall. The body comprises an upper biting surface positioned within an upper channel and a lower biting surface within a lower channel. The outer sidewall and the inner sidewall extend past the upper and lower biting surfaces and define the upper channel and the lower channel, respectively. The upper channel and the lower channel are each able to receive a row of teeth therein. The dental bite block prevents the biting down and provides safe access to the interior of the mouth. A handle extends from the bite block and is releasably tethered to a toothbrush such that the teeth of the subject may be brushed when the teeth are received within the mouth of the subject.

Abstract: A strong joint for hoses for the cooling and crankcase ventilation systems of vehicles is made between a hose 1 and a branch by inserting the flared end 3 of a rigid cylindrical insert 4 into a hole 9 in the hose 1 to distort the margin around the hole. A second hose 6 is then positioned over the insert 4 so that its end abuts the margin of the hole and the joint is sealed and secured by an encapsulation which is vulcanized in situ.A curable polymeric liner 5 may be sandwiched between the insert 4 and the spout 6 and also vulcanized to act as a bond.The second hose may be omitted, leaving the insert as a projection to which a second hose may be fitted by other means.
