Abstract: ABSTRACT OF THE DISCLOSURE             The invention pertains to electric starter motors for internal combustion engines, particularly motors used with smaller engines such as employed to power lawn mowers, snow blowers, lawn tractors and similar equipment.  The motor hous-ing is formed of a dielectric material as to be doubly electri-cally insulated for protection against electrical shock, the motor casing features simplify assembly of the field coil within the casing, and the motor armature shaft portion and starter pinion shaft portion are formed as two components, rather than the usual one piece, permitting separate heat treatment and eliminating the need for shaft straightening after hardening as required when the armature and pinion shaft are homogeneously formed.  Improved frictional engagement between the starter pi-nion and starter drive nut is achieved by the use of a low fric-tion slip ring, and the operating switch for the starter is en-compassed within a dielectric, weatherproof receptacle which may be readily assembled and is tamperproof to protect against shock even under high moisture conditions.

Abstract: TITLE          APPARATUS FOR EXTENDING AND RETRACTING THE CUTTER BARS OF A BORING TYPE MINING MACHINE                    ABSTRACT OF THE DISCLOSURE         A self-propelled  boring type mining machine includes a mobile frame and a pair of spaced apart drive shafts that extend forwardly from a gear box mounted on the frame.  A pair of rotary boring heads are nonrotatably connected to the pair of drive shafts and are operable to cut a pair of bores in a mine face to dislodge the mine material.  Cusps formed at the mine roof and floor are dislodged by upper and lower cutter chains that are carried by upper and lower cutter bars movably positioned on the front end of the frame.   Cutter bar exten-sions are movably positioned on both sides of the upper and lower cutter bars by control links pivotally connected to the extensions and the mobile frame. The upper and lower cutter bars are vertically extended and retracted by piston cylinder assemblies.  Movement of the cutter bars is transmitted to the cutter bar extensions which are guided on the respective cutter bars along combined horizontal and vertical paths.   Thus the cutter bar extensions are automatically moved to an operating position corresponding to a preselected position of the cutter bars for supporting the cutter chains in a preselected cutting position on the mobile frame.

Abstract: APPARATUS AND METHOD FOR FLUE GAS RECIRCULATION IN A SOLID FUEL BOILER             - - - - -ABSTRACT This invention relates to the field of utilizing flue gas recir-culation on solid fuel first  boilers and furnaces.  Flue gas recircula-tion (FGR) in boilers and furnaces is a technique generally known in the prior art.  Flue gas is commonly introduced into a combustion chamber within a boiler above the burning fuel bed.  This continual recycling of the flue gas results in a further burning of smoke and other particulate matter contained therein.  Additionally, the formation of various nitric and nitrous oxides and carbon monoxide gases in the flue gas is reduced thereby minimizing the releasing of these undesirable gases into the atmosphere. The present invention teaches an improvement in the use of recycled flue gase. According to the invention the recycled flue gas is mixed with air and introduced into the primary undergrate combustion air of a solid fuel fired boiler.  An air-flue gas mixture which is at least approximately 25% flue gas supplied in this manner creates a fuel bed that is more reactive than one without this mixture.  By providing this mixture under the burning fuel bed, the temperature of the fuel bed is lowered and excess oxygen is reduced.  A more reactive fuel bed results providing various advantages including improved boiler operation and a clinker-free fuel bed.

Abstract: ABSTRACT OF THE DISCLOSURE      A bundling mechanism for receiving a stream of signatures in overlapping relation on a conveyor belt and for stacking them in register with one another preparatory to separation into bundles for transfer or storage.  A twisting conveyor is provided for helically twisting the stream of signatures substantially 90 degrees so that the signatures are placed on edge.  The outlet of the twisting conveyor is formed of a pair of vertically oriented rollers defining an outlet nip. A stop horizontally spaced from the nip arrests and accumulates the signatures thereby establishing the remote surface of the stack, the stack being supported on a table extending hori-zontally at right angles to the direction of the incoming stream.  The near surface of the stack is horizontally spaced from the nip, the space being bridged by an auxiliary conveyor driven substantially at stream speed for incrementally convey-ing the trailing edge of each signature from the nip into a position which is flush with the near surface of the stack. Packer discs having rollers spaced about the periphery are provided for continuously beating upon the forming end of the stack with the blows being applied in unison over the area of the forming end to facilitate advancement of the stack and sliding of the signatures over one another from the overlapping state into a condition of precise monolithic register.  A conveyor integrated into the stack supporting table assists the packer discs in advancing the major portion of the stack.

Abstract: ABSTRACT OF THE DISCLOSURE                  METHOD OF ETCHING POLYIMIDE           In etching openings in polyimide film, the film is first etched with a basic reagent in its uncured or partially cured state to form the desired open-ings, and thereafter, the film is cured.  However, this will leave a layer of disturbed material surrounding the openings which has absorbed some reagent and will not fully cure and, therefore, not provide topography suitable for reliable inter-connection and metal adherence.  This disturbed material is removed by a second etch in a basic reagent, following additional curing to a sufficient extent to prevent any etching of the polyimide free of absorbed etchant.  Thereby, suitable topography and adherence is provided.

Abstract: Abstract Process for the contact-less removal of material from the surface of a glass object and apparatus for carrying out the process Described is a process for the contact-less removal of material from the surface of an article of brittle material, in particular glass, by means of a laser beam.  So that material can be removed, with sharp edges, without splintering, and also in order to permit non-sharp surfaces, the invention provides that the laser beam (1) is passed through at least one at least partially absorbent matrix (7) and split into a plurality of individual beams (1').  By that means, the energy available in the laser beam is split up, in the beam cross-section, and the individual beams can be adapted to a desired removal effect. The apparatus for carrying out the process is characterised in that the matrix (7) has straight and/or curved fields (8, 9) with preferably a high absorption capability in respect of laser beams.

Abstract: ABSTRACT OF THE DISCLOSURE     Drilling device for forming a borehole with an undercut, includes a cutting edge support mounted in a bearing housing so that it can rotate about an axis of rotation and pivot about a pivot axle extending transversely of the axis of rotation.  A drive member via a drive shaft rotates the bearing housing and the cutting edge support.  Initially, the drilling device forms a cylindrical borehole until the bearing housing contacts the material in which the borehole is formed.  Then, due to relative axial displacement between the drive shaft and the bearing housing, the cutting edge support is pivoted and the cutting edges at the end of the cutting edge support within the base of the borehole makes an undercut.  A stop in the bearing housing engages the cutting edge supports and limits its pivotal movement.  A spring within the bearing housing returns the cutting edge support to its starting position when it is no longer pivoted to form the undercut.
