Patent GB-447776-A (GB)
Abstract: 447,776. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. Nov. 24, 1934, No. 33864. Convention date, Nov. 24, 1933. [Class 106 (i)] Printing on bills and like inserted material.-The release mechanism of a cash register or similar accounting machine is controlled by a slip feeler that is rockable to releasing position either by the insertion of a slip or by disabling means for the slip-printing mechanism. The usual release shaft 26, Figs. 1 and 2, is constantly urged clockwise to releasing position by a spring-pressed link 36 connecting the shaft to the usual motor-control mechanism. This releasing movement of the shaft is normally prevented by means under the control of a release key or keys 11, Fig. 1, and a slip feeler 45, Fig. 2. Depression of a release key rocks a plate 14 and lever 20 counterclockwise to remove the bent end 23 of the lever from locking engagement with a nose 24 of an arm 25 rigid with the release shaft 26. Similarly, the insertion of a slip into a shoot 47 rocks the feeler 45 to remove the hook-shaped end 43 thereof from locking engagement with an arm 42, such arm being connected to the release shaft 26 through a shaft 41, arm 40, link 39 and an arm 38. The release shaft is restored by a stud 33 on a gear 34 forming a unit of the driving train, the arrangement being such that towards the end of an operation a bell-crank 30, 32, pin-and-slot connected to an arm 27 of the release shaft, is rocked by the stud to restore the shaft. A spring-urged lever 35 pivoted to the arm 25 restores the lever 20. In a modification, Fig. 6, wherein the machine is operated by a hand crank, the rotation of a gear 117 of the driving train is limited to one revolution by a lever 114 that is connected to the release shaft 26 and is notched at one end to co-operate with a stop 116 on the gear. The lever 114 and the release shafts are freed prior to an operation by a slight backward rotation of the hand crank. Towards the end of the operation, an arm 123, co-operating with the lever 114 by a cam-slot 124 and pin 125, is rocked counterclockwise by a pin 121 on the gear to restore the lever and shaft to locking position. Disabling means for the slip-printing mechanism. The slip-printing mechanism is driven by a gear 49, Fig. 3, connected to the main shaft through means including a pinion 50 clutched to a shaft 51 that is in turn clutched to a driving wheel 55. To disable the drive, the shaft 51 is moved axially to the right by means of its knurled extension 62 thus disengaging clutch members 56, 57 and disconnecting the shaft from the driving wheel 55. This axial movement of the shaft serves also through a rise 69 on the shaft to rock a lever 70, Fig. 2, counterclockwise and thus through linkage 72 ... 76 rocks the slip feeler 45 to free the release shaft, The shaft 51 is held in its operative and inoperative positions by a spring arm 58, Fig. 3, engaging one or other of two annular grooves 61 in the shaft.

Abstract: 1,183,153. Polyaryl alkylene polyamines. FARBENFABRIKEN BAYER A.G. 20 Sept., 1968 [25 Sept., 1967]. No. 44794/68. Heading C2C. In the manufacture of polyaryl alkylene polyamines by condensing a primary aromatic amine in aqueous solution with an aldehyde containing up to 4 carbon atoms in the presence of an acid catalyst, the reagents are first mixed at - 20‹ to + 40‹ C. in a mixer producing turbulence with a Reynold's number between 10<SP>5</SP> and 10<SP>7</SP>, based on water at 20‹ C., for such a brief period that no reaction can be detected, whereafter the reaction is allowed to proceed in two stages, the first stage being effected at 30-80‹ C. and resulting in the formation of intermediate products containing a methylene or substituted methylene group linked to the nitrogen atom of the amine, and the second stage being effected under turbulence at 80-200‹ C. and resulting in the production of the desired products. Thereafter, the catalyst is neutralized and excess water and unreacted amine are separated. The preferred reagents are aniline, formaldehyde and hydrochloric acid, but others are specified also. The reaction may be effected in an oxygen-free atmosphere, and may be continuous. Examples are given in which aniline, formaldehyde and hydrochloric acid yield final products consisting mainly of diaminodiphenylmethane with minor amounts of triphenyldimethylene triamine, tetraphenyl trimethylene tetramine and pentaphenyl tetramethylene pentamine. Apparatus is described.

Abstract: 1482793 Automatic focusing ASAHI KOGAKU KOGYO KK 16 Oct 1974 [17 Oct 1973] 44866/74 Heading H4D In an automatic focus detector for determining when an image 7, 9, Fig. 4, of an object 3 is correctly focused at consecutive focal planes of an optical system, a bundle of light rays constituting a portion of the light rays passing down the optical system is extracted at one of the focal planes and interrupted from the side at one of the other focal planes, and, downstream of said focal planes, the apparent direction of interruption of the bundle of rays, relative to the actual direction of interruption, is detected to give the sense of the out of focus of the optical system. In the system of Fig. 4, a diaphragm 6 at a first focal plane extracts the central portion of the rays coming from lens 4 and a chopper 10 interrupts the bundle of rays at the second focal plane. For the in focus case (image 9 at the second focal plane) phototransistor or diode detectors 11, 12 give in-phase signals, whilst for the out of focus cases, e.g. Fig. 4, the detector signals will be out of phase. In the ideal case of equal output signals from the detectors and equal trigger levels in the subsequent pulse squaring circuits, the signals produce square waves 39, 40, Fig. 9, of equal duration whereby in a relative phase, pulse counting circuit Fig. 8, the pulse count output 49 need only represent the timing difference between the leading edges of the two square waves. In the "real" case where the durations are not equal Fig. 10, the pulse counts are given for the differences between the timings of both the leading and trailing edges, the difference between the two pulse counts then being indicative of degree of out of focus. The chopper may be at the fixed focal plane, acting on all the light rays from lens 4 and the diaphragm may be at the second focal plane. A mirror, prism or glass fibre may be used instead of the diaphragm.

Abstract: 1,147,358. Automatic control of conveyers. FORDERANLAGEN BAUTZEN VEB. Oct. 27, 1966, No.48302/66. Heading G3R. Tension in the drag chain of a multiple drive endless conveyer, or the speed of one conveyer relative to another, is controlled by a tensioning wheel or differential speed receiver 8, movement of which actuates either of two limit switches 9, 10 and a reversal detecting switch 11 which control, through relays, a servomotor 6 for adjusting the speed of one of the conveyer drives 4. The speed of a second drive 3 is constant but adjustable by a second servomotor 5. The arrangement is such that when a limit switch is operated the servomotor runs to adjust the speed in a correcting sense; over correction begins to occur, the lateral movement of 8 is reversed and this actuates the switch 11 which opens the servomotor circuit for that direction and prepares it for operation in the reverse direction when the other limit switch is reached. Thus, the wheel 8 continually moves between its extreme positions; the period may be increased by an additional switch 14 at the centre of travel which operates the servomotor for a brief, timed, period.
