Abstract: 291,826. Randall, C. E., Thompson, L. R., and Savage, J. C. Feb. 4, 1927. Optical-projection apparatus.-Apparatus for projecting on to clouds or other remotely located screens, comprising a stencilled or other slide placed so that a diverging beam from a light source of high intensity passes through it to a concave mirror or other optical means for projecting the image on to the cloud &c., is provided with reflecting means to divert the projecting beam into a desired direction or to reflect a beam from an image of a real source of light to serve as the diverging beam; the slots &c. in the stencilled slide may have bevelled edges, and the slide may be cooled. As shown in Fig. 8, the slide 2 is placed between a light scource 1 and a mangin or other concave mirror 3, and a rocking mirror 19 projects the reflected beam through a chimney 20 formed on a casing 17 enclosing the whole of the parts. The parts may be relatively adjustable and the casing may be rotatably mounted. Fig. 5 shows a light source 1, a mirror 7 producing an image thereof, and a mirror 8 which reflects a diverging beam from the image through a slide 2 on to the concave mirror 3 which projects on to the cloud &c. A cooling cell 9 may be provided in the beam. As shown in Fig. 6, the mirror 3 may be divided to form two concave mirrors 10, 11 hinged together, and mirrors 14, 15 may be provided for each beam therefrom, the slide 13 being also divided so that its parts may be normal to the optical axis of each mirror 10, 11. The mirror for diverting the projection beam may be divided into two parts hinged together, and the mirror 3 may be replaced by a lens. The slide may be enclosed in a case of glass, quartz, mica, &c. through which a cooling fluid may be passed; alternatively heat conducting bars may be placed in contact with the slide, and water, oil, gas, &c. may be passed through the bars or through passages in the slide itself. Exactly similar slides may be moved in a series past the light source to avoid overheating. The light openings in the slide 2 may have bevelled edges, as shown in Fig. 2.

Title: Improvements in or relating to arrangements for controlling a moving web of strip material
IPC: H02P5/48
Filed: 1962-02-02
Abstract: 923,358. Automatic control of moving webs. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Feb. 2, 1962 [Feb. 2, 1961], No. 4148/62. Class 38 (4). In an arrangement for controlling a moving suspended web of flexible material, the transit time of sound signals transmitted to the web and reflected therefrom is electronically evaluated. As shown, a moving web 1 is fed over rollers 3, 4 into a sag-pit 2. Sound signals from a transmitter 5 are initiated by a pulse-generator 7 and the reflected sound pulse is received by a receiver 6. The time between the leading edge of the transmitted pulse and the leading edge of the received pulse determines the length of a pulse from a pulse former 8 which is a measure of the transit time. This transit pulse is fed to an input of an actual-to-nominal valve comparator 9 wherein it opens a gate 9b to permit a signal from a quartz crystal oscillator 9a to pass to a counter 9c. The number of cycles of the oscillator signal occurring during the duration of the transit pulse is compared with a preset nominal valve signal 9e. The differential output of the counter 9c, through a digital-to-analogue converter 9d, controls a driving equipment 10 for a feed-roller 11 and a take-off roll, not shown, so as to maintain the sag constant. The equipment 10 comprises a Ward-Leonard system supplying the motors driving the feed and take-off rollers and the converter controls a booster generator in the supply to the feed-roll motor. It is stated that the nominal valve signal may be varied in dependence upon the web speed so as to keep constant the time for which the material is in the sag-pit. It is also stated that the gate 9b may be controlled directly by the transmitted and received pulses.

Abstract: 540,175. Cleaning crank-cases and other oilcontaining parts. SAUSSURE, G. E. March 6, 1940, No. 4220. [Class 116] Crank-cases and other lubricant receptacles are cleaned by injecting fluid in an annular path at the centre of which the fluid is withdrawn by suction and filtered before re-circulation through the crank-case &c. or delivery back to a container. The apparatus shown in Figs. 1 and 2 comprises a container and filter unit 27, 28 from which the cleansing-fluid is drawn, by a pump 11, through the conduit 29 to a distributing-valve 10. from which it passes through a pipe-line 32 to a flexible hose 46 leading to an adaptor 49. The latter is adapted for connection to the drain opening 62 of a crank-case &c. 51. The stem 72 of jet 83 passes through the tubular stem 66 of the adaptor 49 and is rotatably jointed to the hose 46. The stem 66 forms the suctionoutlet from the case 51 and is connected by a hose 52 and pipe 40 to a trap 39. A pipe 38 leads from the trap 39 to the distributing-valve 10 which, according to its position of adjustment, controls the continued circulation of the fluid through the case 51, or its return to the container 27. As shown, the pipe-line 32 includes a meter 34 and heater 35. The jet 83, which may be vertically adjustable, as indicated by dotted lines in Fig. 2, is rotated by means of a hand-wheel or the like 85. In a modification, the hose-lines 46, 52 are connected by a teeunion threaded into the adaptor 49.
