Title: Display system and methods
IPC: G06K15/22
Filed: 1965-10-19
Abstract: 1,130,141. Digital plotting mechanisms. CALIFORNIA COMPUTER PRODUCTS Inc. 19 Oct., 1965 [26 Oct., 1964], No. 44286/65. Heading G4H. A digital plotting mechanism for copying a line comprises two electric stepping motors controlling the movement of the mechanism in two orthogonal directions, the stepping motors being controlled by coils which may be energized either singly or in pairs to cause each motor to execute either a full step of rotation (from one coil to the next) or half a step (from one coil halfway to the next coil). In the embodiment described in which the energization of the coils is controlled by for example a digital computer the computer may be programmed to give a straight line approximation either with a minimum plotting time or with a minimum plotting error. Suitable transformations of the co-ordinates are effected so that any line to be approximated may be considered to be in the first quadrant, that is both X and Y positive and with X larger than Y. In the first approximation whole steps are effected at each stage in the X direction with no step or a half step in the Y direction, the Y step being determined by calculating whether or not the Y ordinate of the given line after the next X increment is more than a quarter of a step larger than the Y co-ordinate which was last traced. In the second approximation method in which either a half X step or a full X step combined with a half Y step may be effected, the position of the plotter after each of these combinations is compared with the required position and the combination giving the least deviation is selected. The outputs from the computer controlling one direction e.g. the X direction of the computer are applied on two leads or if negative steps are required three leads to logic controlling three bi-stable devices which when set to their " one " state energize their associated pair of coils to rotate the motor. Since the operation mode is slower if when two coils are set a full step pulse is applied to the logic so that two further coils have to be set the guiding circuit from the motor is arranged to switch the full step signal to a half step operation so that only one coil is energized and succeeding whole steps only necessitate deenergization of further single coils.

Abstract: 1,259,669. Article dispensing machine. SEEBURG CORP OF DELAWARE. Sept. 12, 1969 [Sept 12, 1968(6)], No.45050/69. Heading A4T. An article dispensing machine which may be coin controlled, comprises a set of vertically arranged drawers with tracks 552, Fig. 2 on which are reciprocally mounted article trays 551, the stock of articles being forced up to a stop member 749 at the open rear of a tray by an underlying flat spring fixed to the casing at one end and coiled at the other end behind pusher 559 and the tray being held towards the front of the machine by a catch device 555 interconnected with a pivoted selection button 541. Symbolic device 555 is formed by a stud beneath the tray engaging a spring-loaded calliper clip device, Figs. 11-14, (not shown). Depression of a button releases a catch and allows a spring to project the open rear end of a selector tray rearwards into a vend area 563, and operates vertical and horizontal interlocks preventing release of any other tray. A switch energizes a motor driving endless chains 565 between which is a bar carrying pivoted vend boxes 885, and as the boxes rise, one catches the article at the rear of the selected tray and lifts it towards a top vend area 547 and on which the article falls when a stop 921 tips a box forward. A cam 871 below a box acts on a spring-loaded double-catch mechanism 953 to force the projected tray back into engagement with catch 555 and a limit switch reverses the endless chain. An intercamming catch may allow articles to be dispensed in turn from alternate adjacent trays. In a second embodiment a solenoid switch lifts catch 366, Fig. 38 allowing a spring to move tray 78 rearward and a spring-loaded pusher 262 pushes the end packet 470 against stop 92, Fig. 44, over an end opening in the tray.

Abstract: 1,023,614. Winding layouts for dynamoelectric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 17, 1964 [Nov. 22, 1963], No. 46281/63. Heading H2A. A three-phase motor has pole-changing by pole-amplitude modulation applied to both stator and rotor windings. The modulation may be effected by bringing out switchable connections from both stator and rotor, or one or both of these may be wound so that it presents a short-circuit to one of the pole-numbers. When both are switched, the stator and rotor are brought out to six terminals, the rotor through slip-rings, additional speed control being provided by rotor rheostats in the usual way. Since the rotor is connected to six slip-rings, its winding may be connected in three-phase or six-phase manner to the resistance. In the latter case no rotor switching is required. In an alternative arrangement which avoids rotor switching, the rotor windings are connected in parallel-star (Fig. 3b, not shown), brought out over three slip-rings to a rheostat. At the lower pole-number this connection is operative, but at the higher pole-number each phase is internally short-circuited, thus dispensing with resistive control. This principle of using parallel windings to produce an internal short-circuit at one pole-number may be applied to both stator and rotor windings (Fig. 4, not shown), one winding providing the higher pole-number by parallel operation of its phase-winding parts, and the other winding providing the lower in parallel operation. Either the stator or the rotor windings may be energized to give one pole-number or the other, the de-energized member being effectively internally shortcircuited. As a modification of this arrangement, the corresponding phases of the stator and rotor windings are connected in series, each individual phase winding being connected in parallel-star as before. The relative energization of the stator and rotor windings is determined by a three-phase auto-transformer so as to produce a speed graded from one polenumber to the other.
