Abstract: Apparatus is provided for bending hosels of metal wood golf club heads to alter the characteristics of golf clubs incorporating the heads. A club head is clamped into a rigid clamping framework using a pair of clamps which engage the top and the back of the club head. A bending bar having an adjustable throat for engaging the hosel of the club head is then used to bend the hosel as required.

Abstract: A sampling system includes a plurality of sensing means (3) mounted on one or more beams (2) which reciprocate, over a moving web (1) of material. The sensing zones of adjacent sensing means (3) trace out scanning paths which periodically overlap in a sampling region. One of the sensing means (primary) scans over a known reference to update its calibration periodically or continuously and this is transferred to the other sensing means (secondary) effectively via the travelling material (due to the overlap). Calibration is performed by signal processing means, storing and comparing monitoring signal levels or corresponding digital values derived at positions of overlap and making computations for the purpose of calibration. With sufficient overlap of the scanning paths any one of the sensors can be made redundant. Alternatives include sensing means which move relative to other sensing means as well as rotary arrangements.

Abstract: An apparatus and method are disclosed for accurately determining viscosity of Newtonian and non-Newtonian fluids using a controlled needle viscometer. The controlled needle viscometer includes a vertical sample insert tube filled with the liquid of which the viscosity is to be determined. Using a needle guide at the top of the sample insert tube, a body having a known density is made to fall through the liquid in the sample insert tube.

Abstract: The invention relates to a method and an arrangement for monitoring the operability of a heater of an oxygen-measuring probe which is mounted in the exhaust-gas channel of an internal combustion engine. The principle of operation of the invention is based on the fact that the supply voltage of the probe heater drops during loading by the electrical resistance of the heating element. The voltage difference is dependent upon the magnitude of the resistance and therefore at least the three states can be distinguished, namely: normal operation, circuit interruption and short circuit. The operational state of the probe heater which is so determined is displayed to the driver by activation of a corresponding control unit and/or is stored, as required, in a fault memory. The arrangement according to the invention can be realized by a computer or in a compact configuration and is suitable for use in a central control apparatus.

Abstract: A process for the preparation of a frame-supported pellicle membrane used for dust-proof protection of a photomask in the photolithographic patterning work of, for example, semiconductor devices. An improvement is proposed for trimming of a pellicle membrane formed on a base plate and adhesively bonded to a pellicle frame to remove the extraneous portion of the membrane protruded out of the pellicle frame.

Different from the conventional mechanical punching method, the trimming process of the invention is free from the problem of occurrence of dust particles deposited on the membrane to adversely affect the quality of the pattern reproduction.
