Title: Motor vehicle washing plant
IPC: B60S3/04
Filed: 1950-10-20
Abstract: 686,716. Washing vehicles. EMANUEL, R. Oct. 20, 1950 [Oct. 22, 1949], No. 25653/50. Class 138 (i). [Also in Group XXIX] A motor vehicle washing plant comprises a washing tunnel into which the vehicle may be introduced and spray nozzles arranged in the tunnel and fed with water under pressure, which nozzles are carried by tubular annuli rotatably mounted in the tunnel. In one embodiment, Figs. 1 and 3, the vehicle washer comprises a fixed tunnel 1 provided with a fixed U- section guide 2 and fixed metal guide plate 3 along which a vehicle A may be moved by a chain conveyer 4 connected to a part of the vehicle frame. Above the vehicle a rotatable hub 15 is supported in the top of the tunnel and water is supplied to the hub and through radial conduits 17 to a tubular annulus 18 having jet openings 18a, which jets cause the annulus to rotate by reaction. A similar annulus 23 is provided on one or both side walls of the tunnel, while another annulus 10 is provided in the bottom of the tunnel below the guides 2, 3. The radial conduits 9 of the annulus 10 are provided with vertical pipes 12 having jets 13. In a second embodiment, Figs. 4 and 5 (not shown), the vehicle remains stationary in the tunnel and a spray annulus is movable along each interior side wall of the tunnel. In this case the annulus hub is connected to a slide movable along the wall through the agency of a nut and screw mechanism, the screw of which can be driven manually through gearing or by a motor through belt and pulleys. In a third embodiment, Figs. 6 to 8 (not shown), the tunnel having annuli in its sides and bottom is moved by an endless belt over the vehicle which is stationary. The hubs of the side annuli are supported in the tunnel side walls while the bottom annulus hub is connected to a curved metal tube connected at its other end to the tunnel. The curved tube is also supported by rollers which run in a fixed guide under the vehicle. Although in all the above embodiments the annuli are rotated by jet reaction they may be rotated by mechanical means. The tunnel of the last embodiment may be replaced by a frame comprising two side walls connected together and movable with respect to the vehicle, each side wall carrying a rotatable annulus.

Abstract: 814,516. Water-tube steam boilers. VORKAUF, H. Aug. 15, 1957 [Aug. 16, 1956], No. 25817/57. Class 123(2) In a water-tube boiler comprising a drum 1 supported on a water-cooled tubulous framework, the framework consists of downcomers 2 connecting each end of the drum with distributers 4 for the sidewall riser tubes 9, a transverse distributer 3 for risers 6 forming the front wall of the boiler furnace 12 and joining the downcomers, a transverse collector header 7 also serving as a pre-separator into which the front and rear wall risers 6, 8 discharge and from which downflow tubes 13 convey separated water directly to the distributer 4, a distributer header 5 for the rear wall risers 8 joining the downflow tubes 13 and horizontal longitudinal upper tubes 10 connecting the header 7 with the drum 1 and serving as collectors for the side wall tubes 9. The framework is stiffened by additional downflow tubes 15 extending between the headers 10 and 4, the tubes 15 also serving to convey water separating during the horizontal flow of steam-water mixture in the tubes 10 directly to the lower distributers 4, thus by-passing the drum 1 and further relieving it as regards the separation of steam and water. In a modification, Fig. 2, diagonally disposed tubes 16...19 also connect the members 2, 4, 10, 13 further to stiffen the frame and further to increase the circulation externally of the drum.

Title: Image transmission
IPC: H04N1/419
Filed: 1971-04-19
Abstract: 1332738 Image transmission ROBERT BOSCH ELEKTRONIK GmbH 19 April 1971 [2 April 1970] 25830/71 Heading H4F In an image transmission system a line of information is scanned by a scanner 4 to produce voltages corresponding to brightness values corresponding to black and white regions of the image and fed to store 6. At the end of the line, coding circuit 8 cuts the connection between scanner 4 and store 6 and establishes a connection between store 6 and coding circuit 8. Pulse control circuit 29 supplies to store 6 read-out pulses while the coding circuit 8 counts the number of pulses corresponding to equal brightness voltage values to evaluate the time duration of each such brightness voltage value as a number of pulses. The store is erased simultaneously. The pulses counted by the coding circuit 8 are encoded for transmission. The speed at which the encoded information is transmitted, in the form of pulse blocks, is at a pulse recurrence frequency as near as possible to the maximum transmittable frequency of the transmission channel. After transmission of a line of information coding circuit 8 sends a control signal to control circuit 17 to drive the scanner to the next line. At the end of scanning the coding circuit 8 controls pulse control circuit 29 to stop further read-out pulses being fed to store 6 and interrupts connections between the store 6 and itself and store 6 and scanner 4 which returns to its original position. The receiver essentially involves only a reversal of the sequence of steps carried out at the transmitter, the recording of the recovered brightness values being carried out by an electrode burning the metal coating of a metallic paper for the black values and leaving it unburnt for the white values. A further embodiment, (Fig. 3, not shown), is described for reducing the lost time which occurs between transmission of the pulse signals for respective image lines. In this embodiment an extra store is provided in both transmitter and receiver, the two stores being fed and read sequentially so that continuous transmission of information is provided.

Abstract: 628,432. Magnets. CHAVE, D. M. Sept. 30, 1947, No. 26416. [Class 35] In order to economise in the magnet alloy of a moving coil permanent magnet such as for loudspeaker units or microphones, the cross-seetion of the magnet is progressively reduced from an intermediate position coinciding with the position of maximum flux towards one or both of its poles. Fig; 1 shows a permanent magnet 11 in the form of a ring magnetized parallel with its axis. The magnet 11 has a uniform bore 22 and the outside surface is somewhat barrelshaped so that its cross-section area tapers towards the end parts from a position of maxirmun flux. The magnet 11 is clamped between a yoke 12 and a front apertured member 13 by bolts 17. A central tapered core 18 is bolted to the yoke 12. An annular air gap 10 is formed by the spigotted end part of the core 18 and the member 13. In a modification, only the front end part of the magnet is tapered. In another modification, a cupshaped magnet having the curved wall tapering towards the rim portion is used. In a further modification, the magnet is of the claw type for use with concentric annular pole pieces and it has an integral yoke and four equally spaced fingers having the cross-section reduced towards the end part adjacent the air gap. This reduction in cross-section may be obtained by varying the width of the fingers instead of, or in addition to, the varying of their thickness. In another modification, the magnet is U- shaped, having a central pole so as to form an E-shaped magnetic system and the crosssection of the limbs of the U-shaped magnet is graduated by varying their thickness. Specification 618,802 is referred to.
