Abstract: 1,231,928. Selective printing. SIEMENS A.G. 11 Aug., 1969 [12 Aug., 1968], No. 40091/69. Heading B6F. Type selecting.-Each type-disc 3 of a plurality mounted on swinging levers 4, has a gearwheel 5, which, when in the rest position illustrated, meshes with its respective gear segment 6 for rotational setting, and when moved into the printing position, disengages from the gear segment 6 and engages a detent latch 20. This prevents arbitrary movement of the type-discs 3 during the printing process, and, if necessary corrects slightly the rotational setting. The axial type-setting of the type-carrier system is the result of the superimposition of the latter spacing feed movement and the axial type-setting movement carried out by means of a worm gear drive supported in a cage 9, as described in Specification 1,231,927. Printing is carried out when the lever 4 of the selected type-disc 3 comes into alignement with a type hammer 15. This is previously cocked against the bias of spring 18 by a segmented gear 17 and released when gear segment 16 aligns with cut-away portion 19. The printing hammer assembly and the assembly comprising the type-disc 3, its attached gear and the swinging lever 4, have equal moments of inertia. The common point of contact of the two assemblies is at the same distance from their axes of rotation.

Abstract: 1,233,290. Associative stores; data processing. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1969, No. 48401/69. Headings G4A and G4C. An electronic digital data store comprises a set of information storage cells, the information stored in each cell being represented by the combination of electrical markings on first and second output terminals of the cell, and first and second bit lines connected respectively to the first and second output terminals of the cells of the set, wherein the first and second bit lines are connected as respective inputs to logical connective circuitry which derives a logical function of the signals on the bit lines with each other. The store is associative. The two output terminals of each cell indicate 10, 01, 00 or 11, the last two of these four possible states giving an associative match for any input and an associative mismatch for any input respectively. The bit lines effectively OR the signals from the terminals connected to them when a plurality of words are read out on to them together. Various forms of logical connective circuitry are disclosed for each pair of bit lines permitting fixed or variable logical combinations. Binary addition, incrementing, decrementing and twos-complementing by tablelook-up is possible with reduced table sizes and/or less cycles in general, using the invention. Logical functions of stored operands can be evaluated by read-out. Output from a selected column (but line pair) can be inhibited.

Abstract: 1,250,698. Masted lift trucks. CLARK EQUIPMENT CO. 19 Dec., 1969 [21 Jan., 1969], No. 62138/69. Heading B8H. In a masted lift truck in which forward tilting of the mast is normally limited by the opening of a mechanically-actuated limit switch in the control circuit, a manuallyoperable override switch is provided to permit further forward tilting of the mast beyond the normal limiting position. As shown, when the limit switch 60 is closed, the solenoid valve 54 opens whereby, when a selector valve 34 directs fluid through a line 48 to the tilt rams 30, 30<SP>1</SP>, the return flow from the rams passes through the valve 54. When the switch 60 is opened, the valve 54 closes and cuts off the return flow from the rams 30, 30<SP>1</SP>. If a manually-operated switch 62 is closed, thereby by-passing the switch 60, the valve 54 re-opens to allow further extension of the rams 30, 30<SP>1</SP>. In either position of the valve 54, the mast may be tilted rearwardly by operation of the selector valve 34 to pass pressure fluid through a line 50 and either a passage A or a one-way valve B in the valve 54 to the upper ends of the ram cylinders. The limit switch 60 is mounted on a fixed part of the truck and is actuated by a stepped slide which is movable in a guide on the truck and which is connected by a pivoted link to the mast, Figs. 3-5 (not shown). In a modification, Figs. 6-8 (not shown), the pivoted link is replaced by a telescopic link containing the limit switch.

Abstract: 1,252,767. Remotely controlled fastening. TEXAS INSTRUMENTS Inc. 9 Dec., 1968 [15 Dec., 1967; 4 April, 1968], No. 58419/68. Heading E2A.  An electrically controlled locking device includes a locking element 12 which is movable into and out of a locking position respectively to close and open a current flow path between electrical terminals 1, 2, the current flow path including a thermally responsive element 3 movable, in response to flow of operating current therethrough, to an operating position in which the thermally-responsive element 3 prevents movement of the locking element 12 out of the locking position and an electrical resistance element 6 is connected in parallel with the thermally responsive element 3 to reduce the current flow therethrough, the resistance element 6 being in heat-exchange relationship with the thermallyresponsive element to maintain the latter in the operating position during the passage of the current between the terminals 1, 2. The device is applied to a washing machine, the locking element 12 being used to lock a spring loaded slidable plate 24 in latching engagement with a hook member 27, on the machine. During the latching engagement, the plate 24 carries with it a slide 21 which connects contacts 20, 5 and establishes a circuit between terminals 1, 2 via one arm of the element 3 and contact 5 which is carried by the other arm 4 which also carries a contact 8. The resistance 6 which is U-shaped is carried at the free end of an arm 7 extending from terminal 1 and the free end of the resistance 6 carries a contact 9. The element 3 is connected to the element 12 by a strip 10, and  the arrangement is such that after initial deformation of the element 3, the latter moves the element 12 to the locking position, Fig. 3, thereby closing contacts 8, 9 and connecting the resistance 6 in parallel with the element 3. A permanent magnet 31 on the element 12 prevents disengagement of the latter from the plate 24 due to vibration of the machine. In a similar arrangement, Figs. 6-11 (not shown) a further resistance (104) is connected in series with, and wound on, the thermallyresponsive element, and the contacts connecting the parallel-connected resistance in circuit are adjustable.
