  • Patent number: 4268360
    Abstract: When repairing a gate and vicinity of a coke oven chamber during operation, hot air blowing off the interior of the chamber makes repairs impossible or almost difficult. Disclosed is a temporary heat-proof apparatus capable of preventing such hot air from blowing off the chamber, which generally comprises two units in combination, viz. a heat-proof unit and a charging unit therefor. Both front end portions of the heat-proof unit are expandable toward side walls of the oven chamber, while upper and lower slide frames are arranged respectively to pressure-contact the ceiling and bottom of the chamber.

  • Patent number: 4266400
    Abstract: A wrist watch band comprises a plurality of metallic band links connected by a continuous flexible connecting member in a non-expansile condition. The links are made of pairs of upper and lower strips fixed to each other on respective opposed surfaces thereof. The watch band can be varied in appearance by changing the shapes of the respective upper strips. A method of manufacturing the watch band comprises a sequence of steps which includes forming a series of respective upper and lower strips, fixing the respective upper and lower strips to each other, inserting a flexible connecting member into a series of aligned openings formed and defined between the upper and lower strips and cutting the links and connecting member into designated band shapes. Thus, the method permits watch bands to be manufactured efficiently and at reduced cost.

  • Patent number: 4235676
    Abstract: An elongated tube is maintained at a temperature of about F. throughout its length. Organic waste material such as shredded rubber automobile tires or industrial plastic waste or residential trash which preferably has metal and inorganic matter removed therefrom, is moved through the tube at a uniform rate of speed in the absence of air and/or oxygen, with the material being churned or tumbled as by means of a screw conveyor. The vapors and gases which are produced and/or liberated within the tube are quickly removed therefrom by means of a vacuum of from about four inches to about six inches of mercury, with the vapors being condensed and the gases separated therefrom. The char or residue which is a black, powdery, carbon-type material is also recovered.

  • Patent number: 4234569
    Abstract: This invention relates to a method of production of formaldehyde, and lower saturated aliphatic dialdehyde-treated allergens suitable for the immunotherapy (desensitization) of individuals suffering from allergies of the immediate type in a plurality of steps wherein said formaldehyde and/or said dialdehyde is utilized alone or in combination for the modification of allergen-containing materials. These lower saturated aliphatic mono- and dialdehyde treated allergen-containing materials are useful in ameliorating the symptoms of allergic (atopic) people. Also, they are able to induce formation of blocking antibody in mammals which cross-reacts with the native allergen-containing materials. Reactions with formaldehyde are carried out in a non-phenolic environment in a plurality of steps. The reaction involving combinations of aldehydes can be carried out in a single step.

  • Patent number: 4234875
    Abstract: A security panel arrangement for use with an intrusion alarm system designed to monitor the continuity of a normally continuous signal conductive path and to produce a warning signal when the signal conductive path is broken, which arrangement includes a cellular panel forming a series of parallel elongated passages through which extends at least one means for conducting a signal. The cellular panel is attached to a surface portion of a structure to be secured, and the means for conducting a signal is connected at its two ends to the alarm system in a continuity monitoring relationship therewith. Passage of a human being through the surface portion breaks the continuity of the means for conducting a signal and causes the alarm system to produce the warning signal.

  • Patent number: 4222648
    Abstract: A camera which includes film transport means for moving a strip of film past a lens and shutter assembly in a stepwise, frame by frame sequence, with the film being maintained stationary when the shutter is in the open position. A toothed driven gear is in operative engagement with a film driven reel. A mutilated drive gear having a toothed portion with an end gear tooth and a smooth peripheral portion is rotated in time relationship with the opening and closing of the shutter. The driven gear contains a space between adjacent gear teeth (as by removing one gear tooth) whereby the end tooth of the drive gear is received in said space to facilitate the smooth "meshing" of the drive gear with the driven gear.

  • Patent number: 4215524
    Abstract: An apparatus for packaging a substance in closed bags formed from two continuous ribbons of a thin fragile material in which the ribbons are sealed to each other as they pass downwardly between first and second pairs of horizontal nipping rollers. A bag open at the top is produced from a portion of the ribbons by sealing and is filled with a predetermined amount of the substance to be packaged. The top of the bag is subsequently sealed to close the bag after the ribbons have advanced downwardly a predetermined distance. These operations take place sequentially on successive portions of the ribbons as they advance toward the second pair of nipping rollers, forming a series of sealed bags. At least one of the first pair of nipping rollers has a generally smooth annular concave portion extending between the end portions thereof, while at least one of the second pair of nipping rollers has a generally cylindrical portion of reduced diameter extending between its end portions.

  • Patent number: 4210038
    Abstract: An automatic or semi-automatic lathe especially useful for producing pre-determined optical surfaces on plastic contact lenses. A collet supported on the spindle of a variable speed motor supports a lens blank in coaxial alignment with the spindle. A cutter is held in a vertically adjustable tool post mounted on one of a pair of stacked stages arranged for linear movement radial and axial of the lens blank, respectively. The other stage is mounted on a carriage which in turn is mounted on the base of the lathe and arranged for linear movement radial of the lens blank. A second variable speed motor acting through a pair of cam-operated X/Y drive mechanisms supported on the carriage drives the stages to move the cutter across and into the face of the rotating lens blank, thereby generating any desired combination of concave and/or convex optically curved surfaces. In an alternative embodiment, individual variable speed motors power the X/Y drive mechanisms through sliding wedges or the like.

  • Patent number: 4185691
    Abstract: A novel method for stimulating the flow of oil from the pay zone of a formation traversed by a bore hole which involves the conversion of liquid water into high pressure steam in situ in heat transfer proximity to the pay zone. A novel oil tool adapted to be lowered and suspended within the bore hole in proximity to the pay zone having an external elongated shell within which is contained means for the in situ generation of steam. The casing may be adapted to generate steam internally and allow that steam to pass through the shell and into contact with the pay zone at a predetermined high pressure, or to superheat highly pressurized water and allow it to pass through an orifice in the shell, at which time it immediately flashes to high pressure steam and disperses into the area of the pay zone. A novel electrical control system for the operation, regulation and malfunction-detection of the oil tool from the ground surface.
