Abstract: A label holder which is intended to be mounted in front of the outer end of a rod (3) that projects out from a product display stand or corresponding structure. The rod includes a member (7) which enables the holder (4) to be pivotally mounted to the rod so that the holder can swing vertically. The rear side of the holder (4) includes a number of support surfaces (14, 15). The surfaces are located at mutually different distances from the rear surface of the holder and can be caused to coact selectively with the end surface of the rod (3) or with a rod-mounted member to enable the holder (4) to be adjusted to different angles relative to the rod.

Abstract: A label holder and mounting clip for the mounting and display of electronic labels. A label holder of extruded plastic material snugly receives the enclosure of the electronic label which can be protected by a clear cover extending over the front of the label holder at least slightly spaced from the front of the label. A mounting strip is coextruded with the body of the label holder and is flexibly attached thereto by a co-extruded living hinge. Mounting brackets, of spring metal or the like, are received in pricing channels along the front of display shelving, or are otherwise mounted at the front of the shelving, and include a forwardly displaced, upwardly extending mounting tongue received in a downwardly opening slot in the flexibly attached mounting strip.

Abstract: An engine lubrication system according to the present invention includes a pair of lubrication galleries which extend through the engine block between the ends of the engine crankshaft and communicate with the crankshaft bearing journals through a plurality of lubrication passages. The lubrication galleries are connected to the lubricant pump at opposite ends of the engine. Lubrication passages of one gallery combine with lubrication passages of the other gallery at the crankshaft bearing journals to compensate for the lubricant pressure loss through the galleries with distance from the lubricant pump.

Abstract: A holder for strip-like information carriers for use in shops and stores in conjunction with goods and articles that are displayed on pronged racks. The holder includes a mounting part 1 intended to be fitted to the rack prong(s) and an information-carrier receiver 5 connected to the mounting part. The mounting part is secured to the inwardly located part of at least one prong, and has a cantilever arm 4 which extends above and generally parallel with the prong. The information-carrier receiver is fitted to the forward end of the arm in a manner which allows it to be swung up when removing an article from the prong.

Abstract: An improved control circuit for protecting a high voltage DC electrostatic system from arcing by removing the high voltage from the electrostatic system under incipient arcing conditions. A signal having a voltage proportional to the instantaneous high voltage current in the electrostatic system is established. DC components and unwanted noise and unwanted AC components are removed from the signal to leave only signal components relating to the rate of change of the current in the high voltage system and information indicative of incipient arcing conditions. When the remaining signal exceeds a predetermined reference level, high voltage is removed from the electrostatic system.

Abstract: A method and apparatus for controlling the feedback path in a signal conditioning system. An input signal having signal pulses superimposed on a first d. c. voltage level is applied to a signal conditioner to generate conditioned signal pulses superimposed on a second d. c. voltage level established by a feedback circuit. A first comparator generates a constant magnitude output pulse during the time that the magnitude of a signal pulse exceeds the magnitude of a first reference voltage. The output signal is differentiated and a second comparator generates a control signal during the time the magnitude of the differentiated signal exceeds the magnitude of a second reference voltage. A transistor switch is responsive to the control signal for interrupting the feedback path during which time capacitor means continues to establish the second d. c. voltage level while the signal pulse is conditioned by the signal conditioner.
