Abstract: A wiring housing includes a main portion forming a box and a cover for the box. The main portion has a side wall and a back wall and tubular projections extending from the side and back walls to form conduits sockets to receive the ends of rigid or flexible PVC conduit. The cover has latches and the box has latch sockets to form a three-point snap connection between the components. Openings into the box from the tubular projections form stop shoulders to limit the insertion depth of the conduit. An open side of the box has outwardly sloping textured wall surfaces and the cover has a U-shaped channel fitting over the surfaces which, in assembly, form a water-excludiing closure assembly. The housing assembly is particularly effective for wire interconnections at the junctions of conduit runs.

Abstract: A bottom closure for a beverage container sleeve is made of a soft, flexible polyvinyl chloride and has a short cylindrical sidewall dimensioned to receive the end of an insulating sleeve. The bottom edge of the sidewall is continuously connected to the outer periphery of an annular bottom ring which has a width significantly greater than the radial thickness of the sleeve. A central bottom disk is connected to the inner periphery of the annular ring by a sloping wall, the central disk having openings there through to prevent the formation of an over or under pressure condition within the sleeve when a beverage container is inserted into or extracted therefrom.

Abstract: A regulator circuit for a high intensity discharge lamp includes a magnetic regulator having three windings, the primary and second thereof being connected to line voltage and a lamp. The tertiary winding is connected to a storage capacitor and to a reactor circuit having an inductive reactor and a semi-conductor switch in series. Lamp voltage and current signals are derived by a control circuit which turns the semi-conductor switch on at specific times in each half cycle of operation. The firing angle of the switch is altered to regulate the lamp operating characteristics despite line voltage changes and operating voltage variations resulting from lamp aging and other factors. The control circuit can also be operated as a lamp dimmer circuit.

Abstract: A lamp start, hot-restart and operating circuit for a high wattage, high intensity discharge lamp includes cascaded resonant circuits with capacitors and series-connected inductors connected to an AC source. A pulse circuit including two pulse transformers supplies streamer-forming current, the secondary windings of the pulse transformers being connected in series with the lamp. When the lamp commences normal operation, the operating current energizes a relay to remove the capacitors and pulse circuit from the operating circuit, allowing the inductor to function as the lamp ballast.

Abstract: A thermally readable encoding arrangement can be scanned with a temperature radiation sensor. The encoding arrangement has alternating regions which differ in thermal conductivity, capacity or emissivity characteristics. Heat is either supplied or withdrawn from the encoded region after which the region is sequentially scanned along a path using a radiation detector to evaluate the temperature differences which arise because of the characteristics. Various forms of temperature activation and encoding structures are disclosed.

Abstract: In a process and a material for producing an electrically insulating sheathing around a junction between electrically conductive elements, the material comprises first and second layers which have different melting points and which are disposed around the junction in such a way that the layer having the lower melting point constitutes an inner layer around the junction while the layer having the higher melting point is disposed on the outside of the inner layer. The material is pressed around the junction by means of ultrasound welding, with the inner layer softening at least to such an extent that, under the pressure applied thereto by the outer layer, the inner layer fills any spaces between the junction and the outer layer, and the outer layer forming a sealing enclosure around the inner layer and the junction.

Abstract: A device for storing and applying percussion caps to the nipple of a muzzle-loading firearm includes an elongated sleeve with a loading hole through one side thereof adjacent a first end. A follower member slides within the sleeve and is urged toward the hole by a compression coil spring. A chain extends from the follower through the spring and out of the second end. When the chain is pulled and the spring compressed, percussion caps can be inserted into the device through the hole, forming a row of caps within the sleeve. The caps can then be loaded onto the weapon nipple by pushing the nipple into the hole and extracting a cap, whereupon the next cap becomes available at the hole under the force of the compression coil spring.

Abstract: A chronograph system includes three shot-sensing screens which provide start and stop signals to interval-determining timers. The first screen provides a start signal to both timers and the subsequent screens provide stop signals to the first and second timers, respectively. The time intervals measured by these timers are divided into the distances between the screens to separately calculate two velocities based on two different distances. The calculated velocities are compared to evaluate the performance of the instrumentation so that measurement errors resulting from the instrumentation itself can be eliminated from analysis of the test shots.

Abstract: A liquid chamber (3) arranged in the bottom of the socket cavity (2) is latitudinally sealed by the engaging ball head (4) of the femoral prosthesis shaft. The ball head (4) of the hip joint prosthesis is supported hydrostatically by the liquid chamber (3) filled with synovia and sealed by the ball head following a deformation of the elastic sealing edge (5). By means of the hydrostatic support, the friction moment increases only a little when the load becomes higher and approaches a constant value which is considerably lower than in conventional hip joint sockets.
