Title: Level and slope control for surfacing machines

Filed: 1968-11-06
Abstract: 1,205,109. Graders. BALDWIN-LIMA-HAM ILTON CORP. 6 Nov., 1968 [8 Nov., 1967], No. 52515/68. Heading E1F. [Also in Division G3] A steerable power-driven vehicle supports a ground levelling tool the vertical position of which is automatically adjusted by power means electrically controlled in dependence on the relative vertical position of a horizontal reference band of a detector carried by the tool and a collinated beam of electromagnetic radiation which determines the path of travel of the tool. In Fig. 1, the scraper blade 11 of an earthlevelling vehicle is carried by a ring 21 which is adjustable vertically, or about a fore and aft axis, by control of hydraulic actuators 17, 18. The vertical position of one end of blade 11 relative to a laser beam emitted from a source 30 is determined by a photo-voltaic detector 31 which controls actuator 18 in the appropriate sense to correct vertical deviation of the end of blade 11 from a position in which the laser beam falls on a narrow null zone of detector 31. A pendulum operated potentiometer 41 mounted on the vehicle to determine its transverse inclination is included with a preset potentiometer in a balanced circuit controlling actuator 17 to maintain transverse inclination of the blade at a value determined by the preset potentiometer. Further resistors vary with, and compensate for, changes in attitude of the ring relative to the chassis and the blade relative to the ring. Transverse inclination may alternatively be determined by controlling actuator 17 by a detector 61 responsive to a second laser beam, from a source 60, which need not be parallel to the other laser beam if it is desired that the inclination shall vary as the vehicle travels forward. Simultaneous control of actuators 17, 18 from one detector to determine the height of the blade is also referred to. Detector 31 also responds to the transverse position of the vehicle relative to the laser beam when it is in the null zone of vertical control. Hydraulic steering is then controlled automatically in a progressive manner to maintain the vehicle on a desired course. Further hydraulic actuators may be provided, e.g. to alter the cutting angle of the blade or shift it longitudinally.

Title: Battery charging control apparatus
IPC: H02J7/02
Filed: 1972-11-15
Abstract: 1411560 Battery charging control GENERAL ELECTRIC CO Ltd 14 Nov 1973 [15 Nov 1972] 52683/72 Heading H2H Battery charging control apparatus comprises means to supply four different charging currents, one of which is zero in dependance on the outputs of threshold circuits responding to the battery voltage and a timing circuit. The circuit comprises input unit 4 comprising the threshold circuits, logic circuit 6 and output unit 7 controlling charger 1, The input unit has a multitopped (5) voltage divider to which the battery voltage is fed. A voltage corresponding to the average voltage in each cell is fed to three threshold circuits which generate signals BAT when the voltage is greater than a predetermined value (indicating the presence of a battery); GSV at the gassing voltage (2À3-2À4 V) and EXV at a higher voltage indicating a wrong connection. These signals are fed to logic unit 6. The logic unit comprises a plurality of NAND gates, a clock source and a 16 bit binary counter. It generates signals MCH, ECH and GCH which indicate respectively when the voltage is between BAT and EXV magnitudes; whether the voltage is above or below GSV and when a preset period has elapsed. These signals are fed as control signals to output unit 7 which causes one of (a) a charging current, (b) a lower, gassing current, (c) a still lower, equalizing current or (d) no current to be fed to the battery by charger 1. Operation.-The battery is connected to the charger and providing the connections are correct and EXV=0 0 and BAT=0, charging current is applied to the battery and a count is started. At 24 corresponding to 3 to 9 seconds, the count is stopped. If signal GSV has appeared the current is switched to the equalizing current when GSU appears. If GSV has not appeared charging at the full rate is carried on until GSV appears. Gassing current is then applied for a count of 57, 344 when the current is switched to the equalizing current. This is applied, in either case for a count of 57, 344 corresponding to a period between 2 and 6 hours and the current is then switched off.

[Class 106 (i)] In a calculating machine having a plurality of totalizers means are provided for effecting the engagement and disengagement of one totalizer during the forward stroke of the actuating mechanism and the engagement of a second totalizer during the return stroke of the mechanism and wherein a transfer mechanism common to all the totalizers may be rendered operative on either stroke. One of the said totalizers is a grand totals register that accumulates the amounts entered in the other totalizers. The machine which is of the general construction shown and described in Specification 540,283, comprises keyboard mechanism, differential rack mechanism, totalizer selecting mechanism, transfer mechanism, aligning mechanism, printing means, and total and sub-total taking mechanism. In accordance with the present invention means are provided for controlling the actuation of the grand total register and the selected totalizer during the entering and total-making operations, Entering operations.-The totalizer pinions 11, Fig. 1, for receiving the items to be entered are selected, as described in the above-mentioned Specification and in Specification 540,314, by the axial movement of the operating gear wheels 57. The actuation of the selected totalizer is effected on the return stroke of the differential racks 12 through the agency of intermediate pinions 49 supported on the arms of a control shaft 81. The item set up is also entered in a grand total register 82 during the forward stroke of the rack 12 by the axial movement of a control shaft 89. The control rods 81, 89 are operatively connected to the main shaft 43. The transfer mechanism which is common to these totalizers, operates as described in Specification 540,283, by imparting a step movement to the normally stationary rack 14 in one or other direction after the release of the holding latch 109 or 112. The transfer member 106 is held in displaced position with the pin 105 in the bottom of the inverted T slot in the rack 14 by a trigger 108A. The rack 14 is restored to normal after the transfer operation by the spring means connecting the arm carrying the differential pinion 15 to the bell-crank 35 and the trigger is released at the commencement of the succeeding stroke of operation by the action of an arm 109A on the control shaft 89 whereupon the transfer member is restored to hold the rack 14.

[Also in Division H2] In a method of punching a rigid insert into sheet material, the insert 11 is supported in a punch 10 and the sheet material on a support 26 which is spring-biased at 30, to hold the sheet material above a die 14. In a punching operation the support is first forced downward against springs 30 until the sheet 12 contacts the die face 18 and punching begins. Immediately the support is raised by the springs 30 and the leading end 19 of the insert is driven right through the sheet. If the punch 10 continues to drive the insert downwardly the leading end 19 engages the cutting edge 17 of an aperture 16 in the die and is peened over against the underside of the sheet 12, Fig. 3 (not shown). The method is applicable to inserting metal terminals in printed circuit boards and rivets in metal or other sheets. Alternative shapes for the leading end of the insert are flat, convex and concave. An electric heating coil (not shown) may be wound on to the portion 22 of the die 14.
