Title: Wear Monitoring.
Inventor: BISSETT THOMAS BAIRD
IPC: F02D41/22
Filed: 1967-06-14
Abstract: 1,195,029. Electric measurement of wear; registering use of machines. BISSETT-BERMAN CORP. June 14, 1967[June 30, 1966], No.27508/67. Headings G1J and G1Q. An indication of the state of wear of a machine or other apparatus is provided by deriving electric signals related to the rate of wear and using an electrolytic coulometer to integrate the signals. The coulometer is required to be of the kind in which plating of material from one electrode of an electrolytic cell to another electrode thereof results in a resistance change between the electrodes, the state of wear being inferred from a measurement of this resistance. The cell of Specification 1, 144, 732 is stated to be suitable. Where the apparatus whose wear is to be monitored is an A.C. electric machine, the circuit of Fig.3 is employed. The input electrical device generates A.C. whenever the machine is running and the circuitry shown converts this A.C. to D.C. pulses which are fed to the electrolytic cell 216 which in turn is connectible to the resistance-measuring output circuit 226. The invention is particularly applicable to a vehicle engine, in which case electric signals are derived by means associated with any or all of: (a) the starting switch, (b) the ignition coil, (c) the engine movement, so that the electric circuitry effectively counts, respectively (a) the number of starts, (b) the number of cylinder firings, (c) the number of engine revolutions. A suitable circuit Fig.1 (not shown) is generally similar to that of Fig.3 except that the resistance 206 is replaced by a parallel combination of a capacitor (20) and Zener diode (22) by which the electric pulses derived from the engine are shaped to provide a predetermined pulse form as the immediate input to the electrolytic cell. The circuit may include a temperature-sensitive component so that the state-of-wear indication provided by a given number of e.g. cylinder firings is made dependent on temperature. Fig.4 (not shown) depicts a coulometer consisting of two electrolytic cells connected to four terminals, viz an input pair between which the cells are in parallel and an output pair between which they are in series. This is particularly suitable for use in a wear-indicator designed to be used as 'warrantee monitor', i.e. to indicate a state of wear at which warrantee expires. The stated advantage is that application (by a fraudulent user) of a current to the output terminals merely plates one cell anode and de-plates the other so that no change in output resistance reading can be effected in this way.

Title: Improvements in or relating to apparatus for measuring lengths
Inventor: KUHNE KONRAD
IPC: G01B9/02
Filed: 1965-07-01
Abstract: 1,104,081. Selective signalling. CARL ZEISS JENA VEB. 1 July, 1965, No. 27968/65. Heading G4H. [Also in Divisions G1, G2 and H1] The invention relates to apparatus for measuring lengths or displacements involving the use of a photo-electric interferometer the output of which controls a cathode-ray tube. The displacement measured is that of a triple-reflector member 10 along a scale 13. As the prism is displaced, a photo-electric microscope 12 travels with it to detect scale divisions 14 and produces pulses which are amplified 15 and transmitted to an analyser 16 for counting. The interferometer (e.g. a Michelson interferometer) comprising light source 1, condenser lens 3, diaphragm 5, collimater 6 and filter 7 together with fixed, reference triple reflector 11 and displaceable, test triple reflector 10, mirror 23, partially reflecting plate 9, and objectives 18 and 24, produces two phase-displaced sets of curved interference fringes respectively moving across slits 19, 20. The intensity changes are detected by photodetectors 25, 26 the outputs of which are used to control the movement of the electron beam in cathode-ray tube 31 by the connection of the detectors to the pairs of deflecting plates 27, 28 and 29, 30 respectively. The beam is caused to follow a rotary motion and sweep out a cone shape. A fixed sector disc 33 which may have its sectors electrically insulated from one another, is mounted inside the tube 31 adjacent the screen 32. Each time the beam sweeps across a sector, a pulse is produced which is amplified (at 34) and fed to the analyser 16, where pulses are combined with those from the detector 12 to obtain measurements to fractions of a scale division. In another embodiment (Fig. 2, not shown) the sector disc (33) is outside the cathode-ray tube light from which having passed through the disc interspaces is detected by a detector (35) outside the C.R.T., to produce pulses indicating the fractions of a scale division as before. Alternatives to a Michelson-type interferometer are possible. Reflectors 10, 11 may be replaced by mirrors or right-angled prisms and the phase shifting member 8 by a suitable compensator.

Filed: 1925-11-09
Abstract: 254,586. Boyd, T. A., Boyd, H. A., and Boyd, Ltd., J. & T. Nov. 9,1925. Flyer frames; winding-machines; spindle apparatus; building-motions; spindle-driving apparatus; thread guides.-Filaments exuded from nozzles, for example in the manufacture of artificial silk, are wound upon conical bobbins 13 arranged to have a predetermined and practically uniform " take-up " unaffected by the speed of discharge from the nozzles, and are twisted and wound upon parallel or conical bobbins by means of a flyer so mounted that the bobbin may be removed without removing the flyer. For twisting the filaments a flyer 12, driven by a pinion 11 from a shaft 3, is carried by a sleeve 7 which is reciprocated to lay the filament by a fork 14, the bobbin-spindle 4, or a group of spindles, being moved longlitudinally to build the bobbin by means of a pinion 20 which engages a rack 17<3> on a slide 17. The bobbin-spindle is splined in a pinion 9 by which it is driven, and is connected by a clutch 19 with the slide 17. The pinion 20 is frictionally driven by a shaft 21, so that the slide 17 may be drawn forward by a handle 17<2> to commence the winding on an empty bobbin. The bobbin-spindle is driven at the speed necessary to give the required twist, and, by preference, the flyer is driven a less speed to ensure the required " take-up '' and such speed is varied in accordance with the diameter at which winding is taking place. When winding only, the flyer is omitted, and the bobbin is driven at a variable speed to ensure a uniform " tale-up." The filaments are led over a guide roller 22, which may be stationary or rotating to assist the travel of the filaments and may be used as a lap roller. Specifications 11831/91, 22736/92, and 213,908 are referred to.
