Abstract: 484,821. Calculating - apparatus. GARDNER CO. Dec. 10, 1936, No. 33980. Convention date, Dec. 21, 1935. [Class 106 (i)] A listing adding machine with an item totalizer and a grand total accumulator comprises means under the control of the total key for accumulating totals, and means settable by a control lever for ensuring a grand total taking operation under control of the total key. The invention is shown applied to a machine of the Gardner type as described in Specification 471,364. In the machine shown the totalizers 473 are engaged with the actuator racks 610, Fig. 3, by means of cams 453, 455, on the totalizer shafts in co-operation with rocking plates 419, 421 connected by pin-and-slot means 77. The plate 419 is operatively connected by a link 321 and arm 322 to a rocker 325 controlled by the main operating shaft 301. The rocker 325 is provided with forward and rear cam followers controlled by arms 316, 320 on the shaft 301 to determine whether the active totalizer shall be operated additively or subtractively. When a total is to be transferred to the lower totalizer the total key 278 is depressed and by means of a shoulder engaging a pin 352 rocks a plate 326 to set the rocker 325 to condition the upper totalizer for subtraction so that at the end of the forward stroke the amount stands on the actuator racks 610. Depression of the total key, at the same time through a pin 73 rocks an arm 70 fixed to a shaft 62 which shaft by means of an arm 71 and link 74 operates to engage the latch 75 with the pin 77 to lock the rocking plates in fixed relation so that on the return stroke the lower totalizer is moved into engagement with the actuator racks to receive the amount set thereon. For the purpose of taking a grand total from the lower totalizer a control lever 1, Fig. 1, is moved to active position to render upper totalizer inoperative and condition the lower totalizer for subtraction. At the same time rearward movement of the control lever 1 removes a pin 87 from a spring controlled arm 88 on the shaft 62 which is thereby rocked to withdraw the arm 70 from a position under the pin 73 of the total key. A locking mechanism is provided to maintain the control lever in active position so long as the total key remains depressed.

Abstract: 1360743 Marine moorings CONTINENTAL OIL CO 26 Oct 1972 49408/72 Heading B7S A monomooring comprises a buoy 13 which is connected to a base 11 by parallel pivoted links 14, 15 and which is of variable buoyancy so that it can be sunk to the sea bed. Thus the buoy can be protected from damage caused by passing ships and by the action of waves and sheet ice. The base 11 and the cargo handling pipe passing through it can swivel through 360 degrees relative to a mounting 10 so that the buoy when on the surface, can adopt a downwind position. The buoyancy of the buoy may, as illustrated, be varied by admitting compressed air through line 34 to displace water from the buoy through an opening 40 and by venting air from the buoy though the line 34. The line 34 extends to the shore, Fig. 1B (not shown), where a valve connects it either to atmosphere or to a source of compressed air. In an alternative arrangement, the compressed air supply is replaced by a supply of liquified gas located on the base of the monomooring. In another arrangement, a pump removes water from the buoy.

Apparatus for the transfer of data from substations to central apparatus via a main control circuit includes a feedback shift register at the control circuit and at each sub-station a shift register, the input to which is derived from the first stage of the feedback shift register, the shift registers controlling AND gates which are sequentially enabled to connect the substations with the central station. In the embodiment described the main control circuit includes a scanner sequentially connecting ten sets of up to 100 electricity meters to a meter store which accumulates data in cyclic registers from 50 main control circuits, the meter store being connected to a computer where the meter information is processed. The feedback shift register at each main control circuit has seven stages the output from the fourth and seventh being connected via a modulus two adder to the input of the first stage. Of the 127 possible states of feedback shift register seven are redundant, twenty are used for load control and a hundred are used to cause read out from the meters. At each meter (Fig. 2) each signal from the feedback shift register is gated by the first half cycle of the mains voltage signal (which is used as a synchronizing signal) into the shift register SR controlling a seven input AND gate G2 which is enabled during one of the hundred time slots to transmit the state of meter contact M1 via a gate G1, enabled during the second half cycle of the mains voltage to the main control circuit and meter store. Load control signals are transmitted in the second half of their time slots to a further gate G5 to control a bi-stable device BD. Test scans may be carried out at every tenth scan of the main control circuit, a control signal preceding this scan ensuring a particular response from the sub-stations.

Abstract: 508,397. Sights for aircraft guns. ROE & CO., Ltd., A. V., and BEASLEY, C. R. A. Feb. 4, 1938, No. 3520. [Class 92 (ii)] Automatic training corrections for "own" speed are effected by a cam p, Fig. 7, which is rotated, as by gearing n, o driven by a spurwheel k engaging the fixed training rack j, to convey through a roller r and spring push-rod s, Fig. 2, and lever mechanism t, v, a correcting movement to the bracket 7 carrying the sight 9. The sight-bracket 7 is vertically pivoted at 8 in a saddle 2 trunnioned at 4 in a frame u upstanding from the gun platform. The lever v is turned laterally about a pivot w on a slide 12 by the cam p, rod e and lever t and thereby moves the sight-bracket about its pivot 8 by means of a pin 6. Further, automatic corrections in elevation for " own " speed are obtained by a fixed cam 20 which is engaged by a roller 19 on a spring-pressed lover 17, the pivot 16 of which is carried by an arm 15 moved from the gun cradle by a link 14. The lever 17 thereby moves the saddle 2 carrying the sight bracket 7 about the trunnions 4 to apply the correcting movements in elevation. The adjustment for "own" speed, which is common to both automatic mechanisms, is effected by moving the slide 12 through a screw 10 by turning a knob 11. The slide 12 carries the pivot w of the lever v for traversing the sight and slides over the arm 21 of the lever 17 for elevating the sight. A single adjustment in accordance with a seale of speeds 13 therefore serves to alter the leverage of each of the correcting levers v, 17.

In Fig.2 a photoconductive element 2 responsive to light passing through an adjustable iris diaphragm 1 of a movie camera is arranged in a bridge circuit 2-5 so that deviations of the intensity from a value  determined by the setting of a variable resistor 3 unbalances the bridge in a corresponding sense to render a corresponding transistor 6 or 7 conductive. As a result, transistors 8, 10 or 9, 11 are rendered conductive as well as a transistor 20 to start a multivibrator 12, 13 which then intermittently energizes field coils 18, 19 of a motor M, adjusting iris diaphragm 1. A resistor 14 or 15 is shunted by whichever transistor 10 or 11 is conductive so that the periods of energization of coils 18, 19 are different causing motor M, to run in the appropriate direction to correct the light intensity by adjustment of the iris diaphragm. Modifications are described in which:- (a) the output of the bridge circuit controls a variable impedance transistor in shunt with one of the multivibrator resistors which is greater than the other. (b) a single motor field winding alternately energized in opposite senses by a multivibrator replaces the two windings. (c) one or other of two transistors, SCRs or SCSs cause the motor to operate in the appropriate sense and such operation is made intermittent by the action of a relaxation or other oscillator acting on the semi-conductors or arranged as a chopper in series with the supply. (d) signals are transmitted through photoconductive links or electro-magnetic relays. In all the embodiments the multivibrator is inoperative and the motor fields are not energized when the bridge is balanced. In some embodiments the servo-motor is energized alternately in the forward and reverse directions, one direction predominating to produce motion while the opposite energization produces a braking action which reduces hunting. In other embodiments energization is unidirectional, but pulsed.

Abstract: 1275828 Hand brake pull-rod assemblies DAIMLER-BENZ AG 20 Oct 1969 51314/69 Heading F2E [Also in Division E2] A hand brake pull-rod assembly comprises a guiding and locking bracket 14 having an aperture receiving the pull-rod 110 and communicating with a recess 42 whose depth decreases in that direction of movement of the pull-rod which serves to release the brake, the recess containing a locking member 38 which rests against the rod solely under the influence of gravity so that in "brake on" position it bears positively against the surface of the rod and the bottom of the recess.  Fig. 2 depicts a pull-rod 110 having a handle (not shown) at its right hand end, and pulled in the direction of arrow A to apply the brake. During such movement a ball 38 moves to the wall 40 of a pocket 42 in a bracket 14 and is thereafter free to drop successively into successive indentations 44 as the rod 110 moves beneath it. When the handle is released to leave the brake applied, the conventional brake return spring (not shown) pulls the rod 110 slightly back again until the ball 38, resting in one of the indentations 44, reaches the inclined wall 46 of pocket 42. The pull-rod is thereby locked. The indentations 44 each extend around only a small part of the circumference of red 110, so that the brake may be released by rotating the rod through, e.g. 60 degrees, whereupon the ball is forced out of its indentation, and the return spring is allowed to pull the rod 110 to the left to the brake-release position. The ball may be replaced by a roller and the indentations shaped to correspond. Fig. 3 shows how the bracket may be made in two parts from sheet metal pressings with apertures 56 for attachment of the bracket to the front panel of the vehicle. In Fig. 4 the locking member is in the form of a wedge 238, and no indentations in the rod are needed. For brake release the rod is rotated until a "flat" 60 along the rod is located under the wedge. Means may be provided to prevent the tip of the wedge from entering the gap which is then formed between the bore 212 and the flat 60.
