Title: Bearing arrangement for damping rollers on offset printing presses
IPC: B41F7/40
Filed: 1969-01-23
Abstract: 1,245,896. Rotary printing machines; damping apparatus. ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER A.G. 23 Jan., 1969 [15 Feb., 1968], No. 3788/69. Heading B6C. In an offset rotary printing machine a non- absorbent resiliently covered damping forme roller 1 is mounted in bearing plates 8 which are so mounted about eccentric pivot pins 10 that manual movement of a handle 31 to a first position causes the roller 1 to move away from the plate cylinder 2 whilst still retaining contact with a fixed bearing damping roller 3, whilst movement of the handle to a second position also moves the forme roller 1 away from the roller 3. Movement of the handle in the reverse position naturally re-engages the damping mechanism with the plate cylinder. The roller 1 is mounted between the bearing plates 8 in eccentric bearings 37 to allow contact of the roller 1 solely with the plate cylinder 2 for roller cleaning purposes.

Title: Method and apparatus for coating
IPC: B05D1/32
Filed: 1959-02-04
Abstract: A method of applying a coating to a limited portion of the surface of an article comprises the steps of engaging the said article with a holding device which covers and encloses all sections of the article on which a coating is not desired, heating the article to a temperature above the melting temperature of a pulverulent coating material the temperature of the holding device being below the sintering temperature of the coating material and immersing the article in the pulverulent coating material so that the coating material in proximity to the article surface sinters and fuses into a complete coating said holder being comprised of a non-metallic material which is resistent to coating and which is more resistent to heating than the masked are of the article.  The pulverulent coating material may be in the form of a fluidized bed.  The article to be coated may be heated by electromagnetic induction or by infra red radiation and the holding device may be made from polytetrafluoroethylene, silicone rubber or a chlorinated polyether. Polyformaldehyde or a high temperature resistant nylon may also be employed.  Suitable inorganic non-metallic materials include vitreous materials, e.g. ceramics and porcelains.  Examples are given of coating the outsides of vessels while masking the insides and of coating the outsides and part of the insides of vessels while masking the remainder of the inside and also of holders suitable for coating a large number of small objects such as hooks.

Filed: 1976-01-20
Abstract: 1525954 Controlling light STANDARD TELEPHONES & CABLES Ltd 20 Jan 1976 [30 Jan 1976] 4087/75 Heading G2F An image converter comprises, in order in a stack, a first electrode 19, a liquid crystal layer 21, a photo-conductive layer 12 and a second electrode 10, the latter being structured, e.g. in the form of spaced parallel strips electrically in common, so as not to cover the entire photo-conductive layer and to reduce the dark capacitance thereof, so that a greater proportion of an A.C. potential difference applied between the electrodes is developed across the photo-conductive layer. When an image is incident on the photo-conductor there is local increase in capacitance due to lateral conductivity in addition to the reduction in resistance so that the potential difference is more effectively transferred to the liquid crystal layer. As shown, the layer 21 is a 90 degree twisted nematic layer between an aligning layer 20 of oblique evaporated SiO and a second aligning layer 16. Polarizing layers 15 and 18 are provided, and in some cases layers 15 and 16 may be the same layer. A dielectric opaque CdTe blocking layer 13 separates layer 12 from a mosaic Al reflector 14. The strips of electrode 10 are not necessarily transparent and may be 5Á wide with a pitch of 15Á.

Filed: 1952-02-18
Abstract: 705,778. Heating by circulation of fluids. BAMAG-MEGUIN AKT.-GES. Feb. 18, 1952 '[March 9, 1951], No. 4181/52. Class 64(2) Through a duct 13, at least one gas W, such as hydrogen, helium or nitrogen, is added under pressure to an organic, heattransferring medium, e.g. a mixture of diphenyl oxide and diphenyl in a closed system of which a heat-receiving portion 1 is heated in a combustion chamber. Moreover, a heat consumer; such as an autoclave 5, has an inlet and outlet both above the level of the inlet of the boiler 1. Heat is produced by burning oil or gas G with compressed air L. The gas W, partly absorbed by the liquid heat transfer medium, is boiled out so that vapour and gas are circulated to the autoclave 5. Condensate is returned to a helical receiver 7 and thence to 'the boiler 1. By means of valves 10, 11 and compressed air L forced in through the pipe 13, the system may be emptied when necessary into a tank 9. For filling, valves 10, 11, 12 are opened and liquid from the tank fed in by gravity until the level reaches valve 12, which is then closed together with valve 11. After the gas W is forced in and excess liquid allowed to return to the tank 9, valve 10 is closed and then valve 11 is opened and adjusted to control circulation. A separator 2 returns liquid by a duct 3 back to the boiler. For quick cooling of the autoclave 5 after heating, a duct 8, the receiver 7 or a duct 6 is cooled to cause a short circuit.

Abstract: 1,261,504. Radio-frequency systems. STANDARD TELEPHONES & CABLES Ltd. 29 Jan., 1970, No. 4233/70. Heading H4L. Data to be transmitted in PCM form in such a manner as to be intelligible at a known receiver location but not others is switched between three spaced transmitters on a random or pseudorandom basis, three adjustable delay means being provided between the data source and each transmitter so that the total transmission times from source to a desired receiver location may be made equal for the three paths. By this means the received signal will only be free of random interlacing at the selected location and at most one other. The invention is described in relation to a PCM multiplex arrangement in which one time channel is used for data, which is switched between the three transmitters under control of a noise-controlled distributer, and the other channels carry noise-generated random bits on each transmitter. The data channel may be identified by a code number for demultiplexing at the receiver, the noise channels being monitored for modification if this code should appear. The channel used for data may also be varied to improve secrecy, the instructions for channel change being sent out in coded form on the data channel before such change is effected. Circuits, including self-adjusting threshold circuits producing digital noise are described and illustrated schematically.
