Title: Process for the preparation of waterless lithographic masters

Filed: 1975-04-24
Abstract: 1499355 Preparing lithographic masters  XEROX' CORP 24 April 1975 [28 May 1974] 17039/75 Heading B6C A waterless lithographic .master is produced by imaging, an adhesive silicone layer with a particulate material, both the silicone and the particulate material having reactive pendant groups and causing reaction between the groups, if necessary through a cross-linking agent, so that the particulate material is chemically bound to the silicone. In preferred embodiments the silicones are uncured or only. partially cured and become more ink-releasing when cured, typical pendant groups being vinyl, hydroxyl, amino, isocyanate or thioisocyanate groups; a complexing agent for these reactive groups is incorporated, together with a solvent, into the silicone solution which is coated on to a suitable substrate, e.g. paper or aluminium. The silicone solution can also include a crosslinking agent which is non-reactive until heated, or a nucleophile which is capable of attacking the complexed pendant groups at elevated temperature. The preferred imaging method is electrophotographic using transfer of the latent electrostatic image on to the silicone or directly if the substrate is photoconductive. The image on the silicone is developed using the reactive toner, generally based on styrene polymers with carbon black pigment, and having similar reactive groups to the silicones. Chemical bonding takes place on heating, which destroys the complexes and causes cross-linking between the reactive groups. The resulting chemicallybonded material is then cured.

Title: Improvements in the transmission of sound vibrations from objects between which and a fluid medium relative movement takes place
IPC: G10K11/35
Filed: 1940-12-02
Abstract: 546,338. Locating sounds; signalling by audible signalling. BRIGHT, T. J. R., and FORD, R. C. Dec. 2, 1940, Nos. 17125 and 17131. [Class 118 (ii)] Relates to the reception and transmission of sound waves by or from an object, such as a ship or aeroplane, between which and the surrounding fluid medium there is relative movement. According to the invention, the receiving or transmitting device is moved in the same direction, and at the same speed, as the medium in order to reduce the 'effect of disturbing noises caused by relative movement between the device and the medium. The apparatus comprises a casing 2 having an opening 3 at one side and containing a rotary drum 4 which carries a number of microphones or transmitters 5. The rotor is driven at such a speed that each microphone traverses the opening 3 at approximately the same speed, but in the opposite direction, as the apparatus is travelling through the surrounding fluid. The rotor may be driven by any suitable means, preferably by means of vanes 6 exposed to the drag of the fluid through which the apparatus is moving. One of the leads from each microphone is earthed at 10 while the other is connected with a segment 13 of a rotary switch 14 which connects each microphone with an amplifier during the time it is traversing the opening 3. The microphones become effective in succession and the reception of sound is continuous. The switch 14 may be adjustable about its axis to assist in locating the direction of the source from which sounds are received. The apparatus may be fitted to an opening in the side of a ship or on an aircraft. In a modification, the microphones may be mounted on the face of a revolving disc or carried by a moving belt or conveyer.

As shown, the normally fixed half objective b is held between stops c, d, of which the stop c is vertically movable by means of a screw thread j and a graduated head k adjustable so that the height of the observer reads against a fixed mark m on a part n. A spring e holds the half objective b against the stop d for use on a distant base, but a lever p may be raised by the observer's thumb to engage a sliding pin t and raise the half objective into engagement with the stop c when the instrument is to be used as a depression range-finder. The stop d may be adjustable for infinity setting by means of a screw thread f and head head g covered by a detachable cap h, and corresponding adjustments of the head k in relation to the mark m may be effected when screws o are slackened.

Abstract: 1505750 Multiplex system COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 28 April 1975 [29 April 1974] 17492/75 Heading H4M In a digital multiplex system on which digital data q 1 -q n  on n channels is to be transmitted in frequency multiplex, the digital data is sampled successively at 1 and the samples are used to modulate a base frequency carrier Fo. Thereafter the modulated base frequency is passed to a unit 21, which produces: (a) n coded words representing the phase change #i for a given sample as compared with the phase of the previous sample of the same channel and (b), interleaved with these words, n words representing the phase increments #i of the respective transposition frequencies. These words pass to an adder 23, where they are combined with the output of a memory 24 containing the information from the previous sample of the same channel. The adder output is fed to change the memory and also to control a read-only memory 25 which contains a table of digitally encoded sine and cosine values. The values related to the particular phase are read out to a time shared band limit recursive filter 3 whose output is passed to one input of a transposition circuit 4. This receives at its other input an n interleaved series of digitally coded transposition samples, such that there is produced Si sin (#i+#i) where Si is the maximum amplitude. The transposed outputs are passed to a combining or multiplexing circuit 5 in which the various signals are frequency multiplexed, after which they are passed through a D/A converter 6, and a low pass band limiting filter to the system output.

[Also in Group XXIX] The shaft 18, Fig. 1, of a gyratory crusher is suspended by means of a circular series of hydraulic cylinder and piston units 32, 40 mounted on the flange 26 of a spider hub 16, the pistons being connected by means of bolts 42 to the flange 44 of an adjustment header 46 provided with a flange 54 upon which the upper end of the shaft is supported, and hydraulic fluid is supplied to the lower ends of the cylinders 32 by means of a pipe 64. Compression sleeves 48 surround the bolts 42. The pipe 64 is connected to a pump 72, Fig. 1a, and includes a normally-open solenoid valve 76 which is controlled by an adjustable switch 88, Fig. 1, operable by adjustment means 90 carried by the header 46, when the shaft 18 and header 46 move vertically, the arrangement being such that the valve 76 is closed when the shaft 18 attains a predetermined height. The switch 88 is adjusted in the event of wear of the crushing members. An overflow pipe 68 leads from the cylinders 32 to a reservoir 70. If there should be loss of fluid from around any of the pistons 40 it drains back into the reservoir to permit the switch 88 to close and thus the valve 76 to open so that the fluid lost from the cylinders 32 is replaced until the switch 88 is again opened to close the valve 76. The hydraulic circuit, Fig. 1a, includes an accumulator 78 pressurized by a gas and connected to the pipe 64 by way of a pipe 80 containing a normally-closed solenoid valve 86, the arrangement being such that when the pressure in the cylinders 32 exceeds a predetermined value, e.g. when tramp iron or other uncrushable objects are present in the crushing cavity, the valve 86 is opened by operation of a pressure switch 144 to allow fluid to flow from the cylinders 32 through the pipes 64, 80 into the accumulator, the fluid being returned to the cylinders 32 when the valve 86 is closed by release of the overpressure in the cylinders. The electrical circuits of Fig. la may be replaced by a pneumatic or hydraulic system.

In a push-pull amplifier of the type comprising two alternately conducting stages, negative current-feed-back is derived by combining a voltage obtained from an impedance in the common current path of the amplifier with a voltage across an impedance in the output circuit of only one of the stages. In the transistor amplifier shown the input signal is applied through terminal 1 to one of a pair of emitter coupled transistor stages 2, 4 to provide push-pull voltages for application to the class B or AB push-pull amplifier 6, 7. Negative voltage feed-back is applied to transistor 4 from a tertiary winding 10 on the output transformer and negative current feed-back is applied to transistor 2 and derived by combining the wave 12 developed across resistor 12 with a wave of double amplitude derived from resistor 15. The Specification states that the invention may also be applied to valve circuits.
