Title: Hydroxyl or thiol terminated telomeric ethers
IPC: C08G65/26
Filed: 1968-09-23
Abstract: Functionally terminated telomers, having an average M.W. of at least 300, are prepared by polymerizing a C 2-18 cyclic ether taxogen of formula in which X is O or S, Y is CH 2 or a direct bond between C and X and R1, R2 and R3 are H, hydrocarbon, halohydrocarbon, carbonoxycarbon, carbonthiacarbon, halocarbonoxycarbon or halocarbonthiacarbon radicals with a catalytic amount of a double metal cyanide complex, in the presence of a telogen containing at least one replaceable hydrogen atom selected from a carboxylic acid, carboxylic acid ester, aromatic amide, aromatic substituted urea, a primary aromatic amine, acetylene, a substituted acetylene, a #-ketoester, a #-dinitrile and a #-ester nitrile. The preferred taxogen is propylene oxide and the preferred telogen is an unsaturated polycarboxylic acid, e.g. maleic acid. The catalyst may have the general formula M a (M1(CN) b ) c , where a, b and c are numbers which are functions of the valencies and co-ordination numbers of the metals M and M1. M is selected from Zn (II), Ni (II), Co (II) and Fe (II) and M1 is selected from Fe (II), Fe (III), Co (III) and Cr (III) the catalyst is further complexed with a substantially water insoluble acyclic aliphatic polyether free from active hydrogen and having a M.W. up to 400. The products may be hydroxyl or thiol terminated. Polymers are claimed per se which are derived from telogens as defined above and taxogens as defined above containing 3 to 18 carbon atoms. A product obtained by polymerizing 100 parts by wt. of propylene oxide with 2 parts by weight of p-phenylene diamine in the presence of a zinc hexaferrocyanate-di glyme catalyst is used as an antiozonant in styrene butadiene and acrylonitrile butadiene rubber.

Title: Lighting systems for road vehicles
IPC: F21V14/08
Filed: 1968-01-31
Abstract: In an antidazzle headlighting system for a road vehicle in which an image of the headlamp filament (not shown) is formed in an aperture 15 in a mask 14 and a well-defined image of the aperture is projected forwardly to constitute the beam, a shutter 18 mounted on a winding 30 is movable across the aperture against the action of a spring 33 when the winding is energized by a photo-cell (not shown) sensitive to light received from an oncoming vehicle, the winding being slidable on one limb 27a of a steel frame 27 in the field of a permanent ferrite magnet 28 secured to the other limb 27b. Light reaches the photo-cell through a second aperture 22 which can be covered by a second shutter 32 movable with the first shutter, hunting of the shutters being damped by an extension 51 of the shutter-carrying strip 31 which is slidable in a bore in a block 52 of polytetrafluoroethylene. The block can move within limits determined by lugs 53 over a distance less than the amplitude of the hunting, the coefficient of static friction between the block and the extension being relatively high so that during hunting the block moves with the extension and its inertia, together with the repeated impacts between the ends of the block and the abutments, has a damping effect. The coefficient of dynamic friction is, however, relatively low so that the extension can slide in the bore with little resistance during normal operation of the shutters. In a modification the block is made of some other material and its bore is lined with P.T.F.E. The headlamp is provided with a dichroic reflector which reflects little red or infra red light and the photo-cell is chosen to be most sensitive at these wavelengths so that the likelihood of the system being operated by its own reflected light is minimized.

Title: Registering apparatus
IPC: B41J1/48
Filed: 1969-10-16
Abstract: An electro-mechanical register in which numerical information is fed manually or automatically from say a punched tape or a computer, comprises a keyboard, Fig. 18 (not shown), which operates a combination of switches (1, 2, 4, 8) energizing a corresponding number of solenoids which determine the angular rotation in turn of a set of gears acting as a store, which rotation is transferred to print wheels for parallel visual read out. Energization of one or more solenoids 1, 2 &c., Fig. 17, on partial depression of any key moves a corresponding number of stops, e.g. 172, out of the path of sidewardly movable pins 152 of a friction driven paddle wheel 151 which advances a corresponding number of pins when a "go" solenoid 209 is energized on full depression of a key. On release of the solenoid(s) the pins are returned to the inoperative, i.e., left-hand position. Paddle wheel movement is transmitted through gears to an input gear 105 meshing in turn with each of storage gears 37 which are held from rotation in other than the meshing position by a spline on elements 106, 107. Depression of a print key (500) energizes a solenoid (66) which moves the gears into engagement with racks 13, Fig. 1, and also a solenoid (66A) which engages a machine clutch causing a forward, i.e., left-hand movement of the racks which each advance to a position corresponding to the remainder of the travel of the gears 37 to the zero position and hence print wheels 12 are also rotated correspondingly. Solenoids (66, 66A) are held energized for half a machine cycle by a cam-operated switch (560). The printing mechanism may be of known type and on completion of the left-hand movement of racks 13, a paper tape is brought against the type wheels. Subsequently the wheels are restored in zero position on spring return of the racks to their home position. Information may be entered through a remote keyboard or a local or remote punched tape, and machines may be run in parallel. Electrical signals from the switches may be transmitted to a computer also the printer may be controlled from such computer.

Title: Amplifier circuit for transmission lines
IPC: H03F3/62
Filed: 1972-06-28
Abstract: A circuit for increasing the amplitude of signals transmitted through a bi-directional voice transmission line. A series amplifying network energized in accordance with the voltage across the line produces a signal voltage in aiding relationship to a transmitted signal.

A switching circuit controls the phase relationship between the input and output quantities of each amplifying network in accordance with the direction of transmission of the signal of highest amplitude at any given time, to amplify signals transmitted in that dominant direction and to suppress echo signals transmitted in the other or non-dominant direction. Circuitry is provided to vary the amplitudes of the input signals to the series and shunt amplifying networks as a function of the impedance of the line to provide stable amplification and fidelity of reproduced signal over a wide range of frequencies and transmission line impedances.

Title: Suppression of chrominance signal contamination of the luminance signal in a video signal processing system
IPC: H04N9/78

Abstract: Apparatus in a video signal processing system for improving the quality of a color image reproduced by a color kinescope in response to chrominance and luminance components of the video signal, the chrominance signal being subject to phase transitions likely to generate chrominance subcarrier components sufficient to contaminate the luminance signal. Chrominance signals delayed by an amount corresponding to an interval during which the phase transitions can occur are supplied to inputs of a signal multiplier, which provides an output signal indicating the presence of chrominance phase transitions. The multiplier output signal is utilized for controlling the luminance signal processing channel to suppress the sideband signals, thereby also suppressing objectionable effects of the sideband signals otherwise visible in a reproduced image.
