Abstract: 1,124,691. Accounting machines. SVENSKA DATAREGISTER A.B. 26 Aug., 1965 [18 Sept., 1964], No. 36703/65. Heading G4T. In an accounting machine, a counter register and amount register, each comprising a series of gear-wheels 70, are arranged on the same shaft, and the gear-wheels are moved into engagement with differential members which are moved to read out and print the amount in the amount register, the differential members engaged with the counter wheels being blocked. As described, the invention is applied to the cash register of Specification 995,041. Each pair of registers or register units is obtained by splitting an accumulator of the prior machine, the amount register portion having no tens transfer mechanism and being separated from the counter portion by a blank denomination. In this blank position, is an actuating bracket 24, Figs. 3 and 8, for the counter. Each amount register has entered therein the price of a particular item whose purchase can be registered by depression of a single associated key followed by depression of a function key (72) (Fig. 2, not shown). Upon each such depression, the selected register unit is raised to bring its wheels 70 into engagement with racks 7. The racks engaged with the amount register are then actuated until the register wheels are zeroized whereupon the amount is indicated and is printed on the purchaser's receipt; upon a return stroke of the racks, the amount is re-entered in the amount register. During this operation, the racks 7 for the counter register are held by related slides 27 whose lugs 26 are blocked by lugs 17 on a slide 16 which is set into the position shown in Fig. 5 by a cam 4. The slide 16, through crank-shaft 18, Figs. 3 and 5, also sets a slide 21 whereby hooks 23 are in the path of brackets 24. Thus, when the selected register unit is raised, its bracket 24 is rocked to the position, Fig. 8, together with the adjacent tens transfer bracket 25a whereby " 1 " is entered into the lowest denomination of the counter by mechanism similar to the tens transfer mechanism of Specification 995,041 Upon depression of a further total-taking function key (73), the cam 4 and thus the slides 16 and 21 are adjusted to move the lugs 17 away from lugs 26 and to move hooks 23 away from brackets 24. The total in the counter as well as the amount in the register are then read out and printed. Also, the return movement of the racks 7 associated with the counter is delayed until after the wheels are disengaged whereby the amount read from the counter is not re-entered.

Abstract: 1,225,774. Turning articles over on endless conveyers. RYEMOR ENG. Ltd. 20 May, 1968 [25 May, 1967], No. 24390/67. Heading B8A. A mechanism for turning over relatively flat articles being advanced by a conveyer, includes means 5 for lifting the front of each article upwardly, when it reaches a predetermined point, so that it pivots about its rear edge resting upon the conveyer, and means 6 for engaging the rear edge to prevent sliding movement of the article in a direction opposite to the direction of motion of the conveyer, support means 15 being provided for receiving the article when it overbalances about its rear edge, the lifting means 5 thereafter being lowered to control forward sliding movement of the edge (initially the rear one but now the forward one) of the article. When the leading edge of the panel reaches a trip arm 7, a pair of arms (one only visible in Fig. 1) 5 are turned anti-clockwise by the action of a fluid motor 8 operating via centrally pivoted link 13. A link 10 connected to the motor 8 causes clockwise rotation of a pair of stepped arms 6. The panel is thus turned (Fig. 4) through a vertical position to lie against a member 15 with its trailing edge (now the leading edge) resting on the raised step 6 (Fig. 5, not shown). In this position it operates a control which reverses the pressure in the motor 8. Thus the new leading edge is lowered on to the belts 1 by the member 6, and the member 5, as it drops (Fig. 6), controls the sliding forward movement of the new leading edge until the panel again -lies on the belts 1. For wide articles, the members 5, 6, may be augmented by additional members (5a), (6a) (Fig. 2, not shown).

Abstract: 1,234,500. Indicating damage to conveyer belts. BERGWERKSVERBAND G.m.b.H. 9 Sept., 1969, No. 44465/69. Heading B8A. [Also in Division H4] In a system for indicating damage to a conveyer belt, the belt 1, Fig. 1, is provided with closed conductive loops 2 which may be of metal or, for example, of conductive rubber, which are equally spaced along its length. A high-frequency generator 3 at a fixed point feeds a tuned transmitting coil 5 coupling with the loops 2 and the signal induced in the loops is picked up by a coil 9, which also may be tuned, and supplied to a receiver 7 operating a relay 12 which may be arranged to stop the conveyer if an irregularity occurs in the train of received pulses and/or operate a warning device. The loops may be formed into a T-shape at the edges of the belt. The transmitting and pick-up coils may be arranged with their magnetic axes at right angles to each other to avoid direct coupling and their spacing reduced. In a modification, Fig. 4, the belt is provided with loops 2 which do not extend across the full width of the belt to the edge 15 and each loop 2 is associated with an auxiliary loop 2a adjacent the edge 15 the loops being arranged so that they do not overlap longitudinally. The transmitter 3 supplies signals to the loops 2 and 2a and receiver 7 picks up the signals from loops 2 as before. An additional pick-up coil 8a and receiver 7a co-operate with the loops 2a, the signals from the two receivers being compared at 27 so that if a difference occurs due to damage of one of the loops the belt is stopped by a control device 28. The auxiliary loops may be positioned alternately adjacent the two edges of the belt, Fig. 5 (not shown), in which case two separate transmitters are required. In other arrangements, Figs. 6, 7 (not shown), the auxiliary loops are positioned in lateral alignment with the main loops. In a further modification, Fig. 8, loops 2 are equally spaced along the belt 1 and co-operate with a transmitter 3 and receiver 7 as before, the receiver controlling a relay 17 so that contacts 18a, 18b close each time a loop 2 passes. A pair of permanent magnets of opposite polarity are attached to the belt adjacent to each loop and cooperate with a polepiece 21 forming an extension of the iron core of a coil 20. The passage of the magnets past the coil 20 induces voltages of opposite polarity in the coil which are evaluated in a unit 23 to control the opening of a switch 24. When the belt is operating correctly one or other of the switches 18 or 24 is closed and the circuit 25, 26 remains energized. Should the belt be damaged the contacts 18a, 18b will not be closed when the switch 24 is opened so that the supply to the drive motor via terminals 25, 26 is interrupted. The device 20, 21 may be replaced by a Hall generator.
