Abstract: 1464092 Copying by scanning AGFAGEVAERT AG 31 Jan 1974 [31 Jan 1973] 04638/74 Heading H4F Errors in the angular positions of the mirror surfaces of a mirror drum 24 relative to the drum axis are compensated for by an optical deflector 23 included in the light path before or after the mirror drum 24, the optical deflector 23 being controlled in synchronism with the rotation of the mirror drum to sequentially provide the necessary deflections of the light beam to compensate for the different errors of the separate mirror surfaces. The optical deflector 23 may be controlled by a plurality of fixed frequency oscillators (35, Fig. 5, not shown) the outputs of which are sequentially gated to the deflector 23, or by a variable frequency oscillator 30 controlled by a step voltage generator 31 synchronized by a clock pulse generator 29 and reset by a signal from a light detector 33 receiving light reflected by a marking 34 from a source 32. The optical deflector 23 may be electrooptical, elasto-optical or acousto-optical. If an acousto-optical deflector is used the deflection of the light beam may be controlled by the frequency of the acoustic waves and the intensity of the light beam may be controlled by the amplitude of the acoustic waves to correct for intensity fluctuations of the light beam from light source 21, which may be a laser.

Title: Production of acrylate esters
Inventor: DOBSON KENNETH ROWLAND
IPC: C07C69/54
Filed: 1963-02-07
Abstract: A higher acrylate ester is produced by reacting at elevated temperatures a lower acrylate ester and a higher alcohol in the presence of an alkoxy derivative of titanium as catalyst and a plasticizer oil, hydrolysing the catalyst in the product mixture and separating the titania produced, and recovering the higher acrylate ester by distillation.  The lower acrylate ester is preferably methyl or ethyl acrylate and the higher alcohol an acyclic, alicyclic or aromatic alcohol having from 3 to 20 carbon atoms, e.g. 2-ethylhexanol.  The alkoxy titanium catalyst is preferably derived from the higher alcohol when it is an alkanol.

Title: A machine for mechanically cutting a glass plate
IPC: C03B33/03
Filed: 1966-02-07
Abstract: <PICT:1095864/C1/1> <PICT:1095864/C1/2> In a machine for cutting strips from a glass plate 23, a stationary cutting bridge 7 with a plurality of small cutting wheels 8 is positioned over the upper run of an endless conveyer belt 2 on which the glass plate 23 rests, cutting being effected by upward movement of a pressure roller 3 below the belt 2, the movement of roller 3 being under the control of an operating mechanism which by switches initiates cutting just past the front edge of the glass plate and stops the cutting just in front of the rear edge thereof.  The roller 3 has bearings 4 vertically movable in guides by the pistons 5 of pneumatic cylinders 6 and pistons 5 have contacts for micro-switches 21, both of which must be closed to start the motor for moving the belt 2, thus ensuring the glass plate is horizontal as cutting starts. The operating mechanism comprises a disc 13 on the lower end of a vertically slidable pin 12 on bridge 7, the disc 13, preferably having a square recess 22 for positive timing, engaging the front edge of glass plate 23, rolling or, as shown, sitting on the glass plate during cutting and at the rear edge rolling thereover or, as shown, engaging the rear edge before rolling over, the movements of the pin 12 being transmitted to the circuits of the cylinders 6 and motor for the belt 2 by means of contacts with microswitches 19 and 20 respectively through fixed collars 14 and 15 having a pivoted arm 17 therebetween and a fixed collar 16.  Upward movement of disc 13 opens switch 20 to stop the belt 2 and closes switch 19 to operate the cylinders 6.  As the pistons 5 reach their upper position, switches 21 are closed to restart the belt 2 and cutting commences.  Downward movement of disc 13 just opens switch 19 to vent cylinders 6 and downward movement of pistons 5 opens switches 21 which would stop the belt 2, but which is kept in motion by operation of switch 20 by the collar 16.  The cutting wheels 8, which may comprise diamonds or hard metal, are rotatably mounted on vertical supports 9, each pressed downwardly by a spring 10, the pressure being adjustable for each wheel by a setting screw 11.

In an arrangement for suppressing the printing of non-significant zeros in a computer output printer, individual circuits A1, A2 . . . An are provided for comparing the respective binary coded decimal digits of a number to be printed with zero. The highest order digit a1-d1 is applied together with four leads B from a counter which indicates the position of a printing head (not shown) to direct and inhibitory " and " gates An1-An4, An<SP>1</SP>1- An<SP>1</SP>4. Whose outputs are connected via " or " gates to a further " and " gate An9 adapted to provide an output to control a printing operation via a terminal T1 when the binary digits compared are all alike. The leads a1-d1 are also connected to an " or " gate Or9 which provides an output if there is a " 1 " bit on any of the leads a1-d1 or on an output from an " and " gate h1, one input of which is permanently connected to a " 1 " signal, the other being connected to a jack 12 on a plugboard C. A master jack l1 is connected to a " 1 " signal, the successive jacks being capable of interconnection as shown via connectors PC1, PC2, &c. Assuming first that PC1 is not plugged in, the gate hl produces an output so that when the highest digit is 0000, the gate Or9 produces an output and when the B leads also represent 0000, an " and " gate Anl 1 is opened to feed an output to a terminal T1 to cause " 0 " to be printed. If PC1 is plugged in, however, the gate hl is inhibited so that when the highest digit is 0000, there is no printing control output signal at T1. The connections PC2, PC3 &c. control zero printing in the lower orders.

Abstract: 814,497. Liquid fuel burners. AEBI & CIE S. A. R. Feb. 15, 1957 [Feb. 28, 1956], No. 5318/57. Class 75(1) In a fuel injection nozzle for furnaces employing liquid fuels, the pressure impulses in the fuel supply circuit are used to move an adjusting member by means of which the direction of the nozzle is adjusted step-by-step. The base plate 1 mounted on the wall or roof of the furnace has a bearing cup 3 in which is mounted a rockable plate 5 carrying the nozzle 6. Fuel is supplied to the nozzle through a conduit 10 from a valve 11 which can be adjusted to control the supply of fuel, and which is fed from the supply pump through a cylinder 17 containing a spring biased piston operating a pawl 20 engaging a toothed wheel 21. The toothed wheel 21 carries a pin 26 bearing on the flat surface of a control plate 28, the semi-cylindrical underside of which is mounted in a trough 29 on the plate 5. The pin advances step-by-step with each pressure impulse and if the control plate 28 is inclined to the plane of travel of the pin, the plate 5 will be tilted against the action of a spring 31 producing a corresponding step-by-step variation in the direction of the injection nozzle 6. The inclination of the plate 28 and hence the angle of inclination of the nozzle during a 180 degrees travel of the pin may be varied by a hand wheel. The pawl 20 may be replaced by a pulling device so that the adjustment of the jet direction takes place in the interval between pressure impulses. The arrangement may be such as to tilt the plate 5 about two axes at right angles.
