Title: Tape applying mechanism
Inventor: CHAPMAN ERIC GEORGE ARTHUR
IPC: G03D15/04
Filed: 1969-05-13
Abstract: 1,235,965. Tape-applying machines. ILFORD Ltd. 12 May, 1970 [13 May, 1969], No. 24297/69. Heading B8F. Short sections of adhesive tape are applied to a film travelling on a drum 70 from an intermittently rotating drum 51, predetermined lengths of tape being cut and then transferred from the drum 51 to the drum 70 by a cam-operated arm 31 moving at right angles to the plane of rotation of the drum 51. Tape with one adhesive layer is supplied to the drum 51 with the adhesive layer outermost, the drum 51 having axially extending arms 52 with studs 55 for retaining the tape. The tape is cut by a disc, Fig. 5 (not shown), with a cutting edge, moved axially across the drum surface in either direction by twin rods controlled by a double-acting cylinder. The transfer arm 31 is rotatably held in the arms of an H-section rotating drum 25 and is operated by a cam follower in a track, Fig. 1 (not shown), so that the arm 31 protrudes from the drum 25 at the side facing drum 51, and passes between adjacent arms 52 of drum 51, picking up the tape length by suction ; the drum .25 rotates causing arm 31 to retract inside the drum 25 flush with the drum surface at the opposite side, adjacent to the drum 70, whereby the tape length is applied to the film on the drum 70. For each rotation of the drum 25, the drum 51 is indexed by a Geneva mechanism 41 one-arm sector, and the cutter is reciprocated independently.

Title: Method of testing cellulosic sheet material
Inventor: GARTLAND WILLIAM THOMPSON
IPC: G01N23/16
Filed: 1964-06-11
Abstract: 1,115,904. X-ray testing of cellulosic sheets. REED PAPER GROUP Ltd. Sept. 8, 1965 [June 11, 1964], No.24313/64. Heading G1A. The concentration of a component in cellulosic sheet material e.g. paper is measured by directing a beam of soft X-rays through the sheet and calculating the concentration from the intensity of transmitted X-rays. If the concentration of only one component varies and the mass per unit area remains constant, a single measurement of X-ray absorption suffices. If the concentration of more than one component may vary, measurements are taken at two wavelengths, close to and on either side of an absorption edge of the element to be determined. The radiation is detected by a proportional or scintillation counter and the output therefrom is fed to a pulse height analyzer. By adjusting the pulse height analyzer, the system may be made effectively sensitive to any desired wavelength whilst using a source of broad wavelength range. The measurement may be compensated for variations in mass per unit area by measuring the latter with a #-ray absorption gauge. The invention may be applied to measuring the moisture content of paper produced by a Foudrinier machine.

Title: Improvements relating to interrogating apparatus for determining the optimum frequency for radio communication
Inventor: COVILL DENNIS HENRY
IPC: H04B7/10
Filed: 1964-06-13
Abstract: 1,109,444. Radio signalling; transistor pulse circuits. E.M.I. COSSOR ELECTRONICS Ltd. 14 June, 1965 [13 June, 1964; 20 April, 1965], Nos. 24633/64 and 16673/65. Headings H3T and H4L. In an apparatus for determining the optimum carrier frequency for use in a radio-transmission system, a sequence of pulses of oscillations of differing frequency is set from the transmitting end and means are provided at the receiver for measuring the noise level between pulses to derive a threshold signal, for clipping the received pulses below the level of the threshold signal, and for displaying the levels of the base-clipped pulses. The sequence of pulses is provided by a device 26 and a programmer 27 the start of a frequency sweep being controlled by a standard time receiver 29, and is transmitted by a transmitter 20. The test pulses are received at receiver 21, which is synchronized to sweep through the same band of channels as the transmitter 20, and supplied via a base-clipper 45 controlled by timing pulses 42, 43 from programmer 28 to a display device 55 enabling the station operator to observe which pulse provides the best reception. If it is necessary to initiate a carrier change in the system a selected one of a plurality of buttons 23 is operated, the receiver 11A is changed over to the new channel, a code representing the new carrier is set up at 24, switch 25 is changed over, and the code sent via the normal traffic transmitter 10A to the corresponding receiver 11. This code is recognised by the device 12 at site A which through channel generator 13 changes the transmitter 10 and receiver 11 to the new carrier frequency. At site B the coder 24 having completed its channel change instruction, releases switch 25 and changes over transmitter 10A to the new carrier frequency. If communication is lost between sites A and B, site B will continuously transmit the latest carrier change instruction code and receive on the corresponding frequency and at site A the operator closes switch 15 whereby his receiver will step automatically through the assigned channels in sequence until the changeover code is received. At this point the search stops and the operator at A transmits a message that communication is restored. Transistor base clipper circuit (Fig. 3).-During the interval between test pulses a pulse 42 momentarily causes transistor 75 to conduct and discharge capacitor 71 and noise then charges capacitor 71 via diode 72 and resistor 70 so that the base of transistor 77 is biased correspondingly. During the interval of a test pulse, transistor 73 is rendered conducting by pulse 43 to block diode 72 and the test pulse is supplied to the base of transistor 79 which will conduct and supply an output signal only if the test pulse amplitude exceeds the threshold bias due to noise.

Title: Improved heat resistant insulating materials
IPC: D01F2/00
Filed: 1945-09-25
Abstract: A composition from which heat resistant insulating coatings or films are obtained comprises a cellulose ether and an organo-silicon oxide condensation product consisting essentially of structural units having the formul  R-Si-O1.5 and R12-Si-O in which R and R1 are alkyl radicals, the amount of the R12-Si-O unit being less than 35 mole. per cent, and a common organic solvent.  After application to a surface the solvent is evaporated to produce coatings or films and the solvent-free product is then subjected to heat to convert it into a non-softening condition.  Specified cellulose ethers are ethyl, propyl, butyl, benzyl and ethyl-benzyl cellulose.  The organo-silicon oxide condensation products are obtained by hydrolysing a mixture of compounds of the formul  RSiX3 and R12SiY2 in which R and R1 are the same or different alkyl radicals and X and Y are the same or different halogen, alkoxy or other hydrolysable groups. Colouring matter, pigments, fillers and finely-divided dielectric solids may also be added to the composition.  In examples, a condensation product obtained by hydrolysing a mixture of methyl triethoxysilane and dimethyldiethoxysilane is incorporated with ethyl cellulose in a solvent mixture of toluene-ethanol and the films or coatings cast therefrom are baked.  In one case, the condensation product employed is obtained by hydrolysing a mixture of ethyl silicon trichloride and diethyl silicon dichloride.

Abstract: 655,141. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Sept. 23, 1948, No. 24916. Convention date, Sept. 26, 1947. [Class 38 (iv)] The frequency of an oscillator is automatically corrected to equality with, or fixed frequency separation from, the frequency of a control signal which is derived as an harmonic of a stable control oscillator. In the Figure, the controlled oscillator 2 is to be maintained at a frequency differing from an harmonic of the stable source 1 by a frequency equal to that of the variable auxiliary source 4. Oscillations from the sources 1, 2 are mixed at 3, the amplitude of the oscillation from the source 1 being high enough to cause distortion and thus to produce one or more harmonics. The mixer output is fed to a further mixer 5 which also receives the output of the auxiliary source 4. A low-pass filter 7 rejects unwanted components and supplies a frequency control signal to a valve or other reactance 6 associated with the oscillator 2. The manual tuning means of the sources 1, 2 may be ganged.
