Title: A turning machine, for example an automatic turret lathe
IPC: G05B19/18
Filed: 1980-10-09
Abstract: The automatic turret lathe has a main spindle (14) rotatably seated in a headstock (12) and a turret head (36) mounted on a turret slide and indexed by a fluid-controlled indexing element (38). The movement of the turret slide is controlled by a cam (50) arranged on a first control shaft section (48) by way of a lever system (52, 54). Cross slides (22, 24, 30, 32) are grouped around the main spindle (14) and are also controlled by cams (60, 62, 64, 80) mounted on a second control shaft section (58). Electrically and/or fluid-operated indexing elements (not shown) are also provided for effecting other indexing operations of the lathe. Each of the first and second control shaft sections (48, 58) are driven by way of a control shaft (116) which rotates in conformity with the workpiece. All of the indexing elements are actuated by a programmable control (82) which is triggered by control signals generated by a rotary angle pick-up (118) connected with the second control shaft section (58). Furthermore, the programmable control (82) is equipped with a keyboard (100) for the input of alter statements associated with different angular positions of the rotary-angle pick-up (118). <IMAGE>

Title: Fuel and air injectors for use in gas turbine engines
Inventor: BHANGU JAGNANDAN KUMAR
IPC: F23R3/28
Filed: 1981-06-19
Abstract: A fuel and air injector (27) for combustion chambers (23) of gas turbines using catalytic ignition, comprises two plates (28 and 29) bonded together, each plate having an arrangement of holes, which combine to form apertures (30), and there is also an internal arrangement of passages (32) for conveying fuel from a fuel supply pipe (31) to each aperture (30).

Further mixing of the fuel and air takes place in mixing zone (33). The mixing efficiency for each aperture (30) is proportional to the l/d ratio, where l is the length of the combustion chamber (23) available for mixing, and d is the diameter of the aperture. The l/d ratio and mixing efficiency for the combustion chamber (23) becomes that for a single aperture (30). <IMAGE>

Patent GB-2082807-A (GB)
Title: High frequency ferroresonant power supply
IPC: H01F37/00
Filed: 1981-07-15
Abstract: A ferroresonant power supply having a relatively stable output voltage includes a magnetic element having a saturating core (20) and a winding (22) thereon. A magnetizing current is developed by a source (23) of high frequency voltage for generating alternating magnetic flux in the core (20) so as to develop an alternating output voltage (V out). A capacitor (26) develops a circulating current that generates in a core section associated with the winding magnetic flux that aids in saturating the core section to provide regulation of the output voltage by ferroresonant action. In order to temperature stabilize the output voltage, the saturating core section is formed of a ferrospinel comprising a lithium ferrite or a substituted lithium ferrite. The ferrospinel has desirable magnetic properties of a relatively small change in saturation flux density with temperature, and low coercivity which results in a relatively small temperature rise in the saturating element. The ferroresonant power supply may be used to generate an ultor voltage for a picture tube in a television receiver. <IMAGE>

Title: Safety apparatus for portable heating device
Inventor: WAASDORP PETER
IPC: F23N5/24
Filed: 1982-09-13
Abstract: A safety apparatus for a portable kerosene type heater (10) having a wick (12) includes a heat sensitive member (20) located near the combustion area of the heating device which senses the temperature and produces an indication signal when the sensed temperature exceeding a predetermined temperature generally equivalent to the maximum safe operating level of the heater.

Title: Improvements in or relating to a pyrolysis reaction and apparatus
Inventor: OECK ROBERT C
IPC: C10B47/44
Filed: 1983-08-03
Abstract: A pyolysis reaction apparatus and process are described in which carbonizable waste material is fed into a pyrolysis reaction chamber 10 by an inlet conduit 22 which passes through the wall of a heating furnace surrounding such chamber. As a result, the material is immediately vaporized in the reaction chamber due to the high temperature at the inlet portion of the chamber where the material is introduced. A fluid cooling jacket 56 surrounds the inlet conduit to maintain the temperature within such conduit below the melting temperature of the material being transmitted therethrough in order to prevent clogging of the conduit. The treated material which may contain precious metal, such as the silver in photographic film, is heated within the reaction chamber in the absence of oxygen to decomposed such material. <IMAGE>
