Abstract: A bouquet ring for fresh flowers or an artificial nosegay comprising a support base; bendable grasping prongs extending from the support base and adapted to grasp fresh or artificial flowers, a wet or dry synthetic foam-plastic flower support, or a tube-type flower support; a size-adjustable ring band adapted to be placed on a finger; and a rivet connecting the ring band to the support base.

Abstract: A unit dose ampul for a jet injector has a tube open at one end and an integral nozzle at the other end with a piston in the tube to seal the open end of the tube and to advance liquid in the tube through the nozzle. A sealing cap encompasses the nozzle and the forward end of the tube and is secured to the tube, the cap having a peripheral area of weakness adjacent the nozzle of the ampul whereby a portion of the cap can be broken off to expose the end of the nozzle. The cap has an interlocking portion for removably securing the cartridge to a jet injector.

Abstract: A pressure operated injection device supports an ampul containing a plunger. A ram which actuates the plunger is spring biased to a retracted position and is advanced by a gas under pressure. A source of gas under pressure is connected by a passage to a gas accumulating chamber which in turn is connected by a passage to the ram with a valve being provided in each passage. The valves admit gas to the ram from the accumulating chamber at a predetermined pressure and simultaneously prevent the admission of any further gas from the source of gas and, at a substantially lower pressure, close the passage connecting the accumulating chamber and the ram. The device is constructed to exhaust gas to the atmosphere from the ram as it retracts and a manually controlled valve controlling the flow of gas from the source to control the operation of the device.

Abstract: A tennis ball marker which has no moving parts in operation and in which a plurality of removable and interchangeable heating imprint modules are mounted in a housing containing an electric circuit for controlling the supply of power from a source to heat the imprint modules. The imprint modules comprise a ceramic body having an electric heating element embedded therein. The top surface of the ceramic body provides raised portions in the shape of letters or other identifying indicia which are seared onto the surface of a tennis ball placed in contact therewith. The imprint modules are readily interchangeable and are removably plugged into electrical receptacles in the housing to permit the identifying indicia to be readily changed. The housing includes window means through which the imprint modules are exposed.

Abstract: A buried oil transportation pipeline is provided with a dual sheath for recirculating liquid coolant under pressure. The liquid coolant eliminates thermal interference with the environment, provides means for detecting oil leaks and for recovery of leaked oil, and further provides for improved oil throughput.

Abstract: Medicinal capsules which are secured by machine to a backing strip are photoelectrically inspected by multiple pairs of light sources and detectors specially arranged so as to permit the simultaneous inspection of a number of closely spaced capsules arranged in a row. The extent to which a capsule is filled is determined by the time interval during which a light beam is blocked by the capsule contents. This interval is electrically compared with a standard time interval. After the backing strip is cut into separate cards, each carrying several capsules, the electrical comparison means effects rejection of any card containing an unsatisfactory capsule. Further means are provided for similarly rejecting cards having badly misaligned capsules. Should the apparatus sense an excessive number of unsatisfactory cards, the packaging machinery is automatically shut down.

Abstract: A fire hydrant designed to prevent the unauthorized use of an outlet nozzle which is located on the above ground barrel portion of the stand pipe. The hydrant includes a valve means located within the barrel portion and provided with a valve member which is biased to a closed position extending across the upstream end of the outlet nozzle. A valve actuator is provided to be threaded onto the outlet nozzle for moving the valve member away from the closed position to an open position permitting the flow of water through the outlet nozzle.

Abstract: A slip joint construction for a tubular pole section of a utility pole such as for electrical transmission or lighting wherein a male portion of a tapered pole section fits telescopically within a female portion of another tapered pole section. The female portion is provided with a back-up strip extending along the long seams thereof. The male portion is provided with slots which extend along the long seams thereof, each slot extending the length of the slip joint. A doubler plate is welded on the inside of the male portion to extend across and along the longitudinal extent of each slot.

Abstract: A combined tennis racket cover and support press including a case made of stiff material such as plastic and adapted to receive a tennis racket head, which case includes a bottom frame portion hingedly connected to two top half-frame portions which may be opened to receive the head of a tennis racket and closed and locked against springs urging open the top half-frame portions. The case provides a stiff enclosure to protect the racket against physical damage and contains pressure pads for applying pressure onto the head of the racket to prevent warpage.

Abstract: A fuel is produced by cleaning coal using an oil as a cleaning medium whereby the sulfur content of the fuel is substantially reduced and the heat content per pound is substantially increased by the reduction of water and other non-combustibles. The process may be used to produce a coal-oil fuel directly.
