Title: Converting rotary motion into reciprocating motion and vice versa
Inventor: CANVIN CLIFFORD HARRY
IPC: F16H19/04
Filed: 1990-08-31
Abstract: A device for converting rotary motion into reciprocating motion comprises a Gearbox G pivotably mounted on the axis of Driveshaft D5, suitably upheld by Bearing-means D4 above a Bedplate B, and having two external sprocket driving means G13a and b rotating in opposite directions alternately engaging with a rack C in the form of a roller chain mounted for reciprocating motion upon said Bedplate. Means are provided to pivot the gearbox when the rack reaches the end of its travel thus producing continuous reciprocating motion of the rack. Latching means La, Lb prevent the gearbox from pivoting prior to reaching the end of a stroke, and cam surfaces C7 unlock the gearbox at the end of each stroke and allow it to pivot. The above device may be modified and used to convert reciprocating motion of the rack into a continuous rotary output. In this case the two sprocket wheels are in continuous mesh with the rack and are mounted on their respective shafts through oppositely acting one-way clutches. The device may be used in association with piston-cylinder pumps. <IMAGE>

Title: Gas detector for sulphur hexafluoride decomposition products
Inventor: SHIRO YAMAUCHI
IPC: G01N27/416
Filed: 1991-02-07
Abstract: The detector comprises a detecting electrode 2 having a predetermined quantity of a metal element, a solid electrolyte 3 containing ions of the metal element, a polarisation electrode 4 which does not transfer ions of the metal element, a second solid electrolyte 5 containing ions of the metal element and a reference electrode 6. A platinum supply electrode 1 is formed on detecting electrode 2 and a power supply 7 is reversibly connectable between the detecting and polarising electrodes. The metal may be copper, silver, lithium or sodium. In use, power supply 7 is connected to electrodes 2, 4 so that the metal (eg silver) in the solid electrolyte 3 is deposited on electrode 2 and, due to cation depletion in solid electrolyte 3 adjacent polarisation electrode 4, a potential Vao is set up between the polarisation and reference electrodes 4, 6. Detecting electrode 2 is exposed to decomposition products such as fluorine which attack the silver layer and change the resistance between electrodes 2 and 1. On detection of a resistance change, power supply 7 is connected in the opposite sense to retain silver ions from electrode 2 to solide electrolyte 3. The potential between electrodes 4 and 6 (Va1) is then measured and the difference between Vao and Va1 is a measure of the degree of decomposition. <IMAGE>

Title: Alarm systems
Inventor: CHITTLEBURGH WILLIAM FRANCIS S
IPC: A62B3/00
Filed: 1992-07-01
Abstract: An alarm system comprises an optical projector 12 adapted to project a sign image, a detector 10 for determining an occurrence which requires display of the image and a switch responsive to the detector for actuating the projector to cause projection of the sign image upon detection of the occurrence. Preferably, the detector causes emission of an acoustic signal which is picked up by a receiver 16 to cause actuation of the projector. In another system, Figs 7 and 8 (not shown), a detector, eg a smoke detector, or a manually operated device, causes emission of an acoustic signal which is picked up by a receiver to cause emission of a further acoustic signal. This principle may be used to cause a chain reaction of acoustic alarms in a network. <IMAGE>

Title: Waveguide rotary joint
Inventor: GHOSH SUBIR
IPC: H01P1/06
Filed: 1992-12-04
Abstract: The rotor 14 of the joint includes two rectangular waveguide ports 18A, 18B, carrying two separate signals. The stator 16 has two corresponding rectangular waveguide ports 23A, 23B. The ports are coupled with a circular waveguide 20, which comprises two relatively rotatable stub-cylinders 21, 25, disposed co-axially in-line on the axis of rotation 27. Signal A is transmitted through the circular waveguide, across the joint, in the TM01 propagation mode, while signal B is transmitted across the joint in the TE01 mode. These circular-symmetrical modes, with mutually orthogonal field distribution, are able to cut crosstalk interference, since the mode transducers of these modes maintain good mutual isolation, even though the signals are present together in the circular waveguide, and at the same or similar frequency. The TM01 mode (signal A) is excited, and received, by means of slots 36 formed in the end wall 34 of the circular waveguide stubs. The port for signal A communicates with the circular waveguide through the two slots. The TE01 mode (signal B) is excited, and received, by means of four axial slots 40 formed in the cylindrical wall of the circular waveguide. The transducer for signal B is disposed in a wrap-around relationship with the circular waveguide, and is in communication with the circular waveguide through the four slots. An E-plane junctional continuation 47 communicates the port for signal B, via two slots, with the transducer for signal B. <IMAGE>

Title: Mixing apparatus for materials in a reactor
Inventor: KNACKSTEDT HANS-GUENTHER
IPC: B01F7/16
Filed: 1993-06-07
Abstract: An apparatus for the through mixing (prior to cleaning) of materials, for example hydrocarbon contaminated soil, slurry or metal shavings in a reactor comprises a portable unit (1) including at least one rotatably drivable mixing tool (2, 3). The tools (2, 3) are suspended from a mounting device (31) so that they are able to execute a resiliently yielding movement, within limits, if the tools encounter a resistance e.g. stones, in the material being mixed. This can be accomplished by the use of universal (Cardan) joints (20) and V-shaped stabilisers (25, 26) supporting the tools through self aligning roller bearing (23, 24) so that the tools cannot yield in the plane of the stabilisers but can yield in the direction perpendicular thereto. In this way the tools (2, 3) cannot mesh and interfere with each other. Runners (37, 38) can receive the forks of a forklift vehicle. <IMAGE>

Patent GB-933991-A (GB)
Abstract: 933,991. Engine turning gear. SCHWITZER CORPORATION. June 26, 1961 [Aug. 8, 1960], No. 22971/61. Pneumatic starting apparatus for an internalcombustion engine comprises a pneumatic motor a shaft driven 13 thereby a pinion gear 48 movable axially. along the shaft for engagement with the engine flywheel gear 52, a housing, a piston 26 slidable within the housing, means mechanically linking the pinion gear and the piston including a drive collar slidable axially on the shaft for axially displacing the pinion gear by the piston, the housing having an air inlet passage 29 therein communicating with a space at one end of the piston whereby upon the introduction of control air under pressure into the inlet passage the piston is moved to cause the pinion gear to engage the flywheel gear and the housing having an air outlet passage 67 communicating with the space accommodating the piston the outlet passage being positioned so as to be uncovered by the piston as it completes the pinion engaging movement thereby allowing control air to flow through the outlet passage only when the pinion gear has engaged the engine flywheel gear. If the push button 93 is actuated control air pressure will be admitted to the line 94. This serves to pressurize the annular chamber 28 and moves the piston 26 to the right. This movement of the piston 26 engages the pins 32 with the channel member 36 and slides the sleeve 37 to the right along the shaft 13. This motion of the sleeve 37 is transferred to the member 41 and consequently the pinion gear 48 through the spring 64. In the event that the teeth of the pinion gear 48 are not properly aligned with the teeth of the ring gear 52 as they engage each other movement of the member 41 will be halted but movement of the sleeve 37 will continue. This relative movement between the sleeve 37 and the member 41 will compress the spring 64 somewhat and because of the spiral splines between the sleeve 37 and the member 41 the pinion gear 48 will be rotated slightly so as to press the pinion teeth into mesh with the ring gear teeth. As the pinion completes its movement to the right the passage or chamber 66 will be uncovered by the piston permitting communication between the passage or chamber 66 and the chamber 28. Control air pressure will thus be caused to exist at the outlet aperture 68 and in the line 96. This causes the valve 89 to open thereby admitting high pressure air to the inlet aperture 84 of the vane type air motor. When the engine starts the over-running clutch 56, 57 prevents transmission of torque from the engine to the shaft 13. The apparatus is suitable for starting compression ignition engines but may also be applied to spark ignition engines.

Patent GB-2283112-A (GB)
Title: Power tool with automatic downshift
Inventor: NAUMANN WILLIAM L
IPC: B25B23/14
Filed: 1994-10-17
Abstract: A method and apparatus for correcting torque overshoot in power tools wherein torque rate is sensed on each rundown and the speed of the tool is automatically adjusted if necessary to maintain torque accuracy. In setting threaded fasteners, joint rates are defined as high (hard), medium or low (soft). Two torque points are defined at percentages of the target torque, for example 25% and 50%. Two angle values are defined as the angle of rotation between the first and second torque points for typical hard and medium joints. Two final tightening speeds are defined as percentages of full speed corresponding to the tool system requirements for accurate shutoff on hard and medium joints. A controller measures the angle between the first and second torque points. The angle measured is compared with the hard and medium angles to determine the joint rate. If the angle is less than or equal to the hard angle, the joint is hard and the controller downshifts the tool to the hard speed. If the angle is greater than the hard angle but less than or equal to the medium angle, the joint is medium and the controller downshifts the tool to the medium speed. If the angle is greater than the medium angle, the joint is considered soft and the speed is not changed.
