Title: Method of and apparatus for producing a needled non-woven fabric film projectors
IPC: D04H18/00
Filed: 1973-01-12
Abstract: 1449641 Uniform needled webs WIRA 31 Dec 1973 [12 Jan 1973] 1766/73 Heading D1R A fleece is needled to form a fabric of controlled weight/unit area, the fleece being drafted prior to completion of the needling and at least part of the drafting occurring where the fleece is needled, the extent of the drafting being automatically controlled in dependence at least partially upon the fleece or fabric thickness. As shown a corded web 1 is crosslapped onto conveyor belt 2 to form fleece 4, compressed by roll 18 and drafted between rolls 7, 8 and 11, 12 whilst being needled. The circumferential speed of rollers 11, 12 is initially set at 1.2 to 4 times that of rolls 7, 8. Roll 15 is spring urged against roll 12 to sense the thickness of the fabric. If a portion of the fabric is thicker than desired the displacement of roll 15 causes position transducer 17 to activate drive means 13 so as to increase the draft ratio. A thin portion leads to a reduction in the draft ratio. Many modifications are specified. Additional drafting may be obtained by increasing the speed of conveyor 2 relative to crosslapper 3. The sensing means may comprise a pair of rollers spaced from drafting rollers 11, 12. A periodic signal may be superposed upon the correction signal produced at 17 to produce a fabric with an undulating surface. The position transducer may be replaced by a pneumatic or hydraulic control or the combination of 15 and 17 replaced by thickness detection means based upon the absorption of light or beta rays. The corded fleece may be replaced by a spunbonded web.

Abstract: 909,445. Photo-electric comparison of light beams. PERKIN-ELMER Ltd. Dec. 23, 1960 [Jan. 18, 1960], No. 1801/60. Class 40 (3). Means for comparing the intensities of two light beams include a logarithmic attenuator in one beam which is automatically adjusted until the intensities are equal. Light from a source 1, Fig. 1, is directed by a rotating chopper 10, Fig. 2, comprising reflecting, transparent and opaque segments 12, 16 and 20, along paths 14 and 18 alternately to a detector 30. The output of detector 30 at the chopping frequency fo, proportional to the intensity difference I<SP>1</SP>-I, is demodulated in the rectifier 36 and used to adjust the position of the logarithimic attenuator 22. It is shown that, with a logarithmic attenuator, to maintain constant gain in the servo system, I<SP>1</SP>kc must be kept constant where k is the sensitivity of detector 30 and the preamplifier 32 and c is the gain of units 34, 36 and 40. The output of detector 30 at a frequency f 1  = 2f 0  is proportional to I<SP>1</SP>k. This output which appears at amplifier 52 may be made to control the source intensity or the width of slits 2, 3 to keep I<SP>1</SP>k constant, or rectified and applied to the grid of a pentode, Fig. 3 (not shown), to the cathode of which is applied a reference potential. Variations from the reference potential cause variations in the anode potential which are applied through a cascade stabilizer to control the dynode potential of a photomultiplier constituting detector 30. In these systems, the gain of amplifier 40 must also be kept constant. The output of amplifier 52 may alternatively control the amplifier 40 so that c is inversely proportional to I<SP>1</SP>k. In the Provisional Specification a variable Á valve is included in amplifier 40 for this purpose.

Abstract: 357,053. Apparatus for recording the passage of trains. WETZER,R., Pfronten, Bavaria, Germany. Jan. 26, 1931, No. 2514. Convention date, Feb. 12, 1930. [Class 105.] A recording device for investigating the speed of vehicles comprises three, switches placed in the path thereof, the first switch actuated by a vehicle travelling in either direction releasing the driving clock of the recorder, the actuation of the remaining two switches causing the recorder to record a mark the length of which is a function of the speed of the vehicle. A vehicle passing over switch I completes a circuit from the battery f, through the earth, through switch c, electromagnet u<1> and time switch z. The magnet armature b is rocked to the left, closing contacts h, k, i and opening contact d. The closing of contact i establishes a circuit/, n, i, t, m to operate an electromagnet t which releases the clockwork mechanism of a travelling-tape recorder w. When the vehicle passes over switch II a circuit is formed through the electromagnets y to operate the marking device on the tape, a retaining contact x continuing the record until the vehicle passes. over switch III. When this happens, a circuit f, e, III, k, V is made, V being a relay which causes the opening of contact m to release the recorder magnets y, t. The operation of the relay V also closes a switch o in circuit with a clock-winding magnet p of the time switch z. This switch z momentarily opens the contact g a certain time (e.g. 15 secs.) after the vehicle has passed and so releases the armature b and resets the apparatus. A vehicle passing in the opposite direction closes switch III and operates magnet u2 which then prepares the circuits for operation by switches II, I.
