Patent GB-1232855-A (GB)
IPC: G05B19/33
Filed: 1968-08-02
Abstract: 1,232,855. Programmed control of machine tools. NIPPON ELECTRIC CO Ltd. Aug.2, 1968, [Aug.3, 1967], No.36934/68. Heading G3N. In "phase selection" digital driving equipment, in which the acutal position of a member is indicated by polyphase signals and a "command position signal" selects one of these phases whose magnitude then causes a drive (fluid motor, stepping motor or other electric motor) to reposition the member until the magnitude of the selected phase reaches zero, means are provided for interrupting the command signals when a selected one of the polyphase signals indicates that the difference between the actual and the commanded position is excessive. The invention is applicable to the numerical control of the feed of a machine tool in one or more axes. The polyphase position signals may be generated by a ten-phase synchro or an equivalent Hall plate device and Fig.6(a) shows two typical phases #5, #6. A phase #P is "selected" by the position of a decade ring counter (phase selector 3-2 in Fig.1) which is stepped up or down by pulses and directional signals 53 which are produced by devices 1 and 2 from the input information. If for example, the count corresponds to #5, i.e. #p = #5, the operating point Pp is at zero Ao and the controlled member 4 is not moved; however, the next input signal will switch the count down to #4 or up to #6, in the latter case switching the operating point Pp to Bo. The magnitude of #6 operates through phase disimminator 3-3 and servo drive 3-4 to move 4 in the appropriate  direction so that Pp follows the curve #6 until the zero point To is reached. Since To represents the desired position and Pp the actual position at any instant the difference between them Do represents the "droop". According to the invention, if this becomes eccessive the command signals S3 are stopped by blocking command signals S1 at gate 8. This happens when a signal S5 becomes logic 1 due to an "alarm signal" S4 being greater than a reference signal SR. S4 is the magnitude of one of the phases of the position signal, selected by a second counter 5 whose count is always a predetermined number (which can be zero) removed from that of 3-2, and it becomes excessive if the command signals arrive at a rate greater than the controlled member 4 can follow. In a modification Fig.16, (not shown) better control during deceleration is achieved by an arrangement which adds or substitutes separately generated "low speed command" signals to the signal S2 of Fig. 1, when prescribed droop conditions occur. In multi-axial systems individual alarm devices 5, 6 and 7 are provided for each axis and the logical sum of their signals S5 is applied to the gate 8.

Abstract: 1,265,131. Reciprocating dispensing pumps. DIAMOND INTERNATIONAL CORP. Jan. 8, 1970 [Jan. 17, 1969], No. 938/70. Heading F1A. A hand-actuated liquid dispensing pump is adapted to be secured to a container and comprises a piston 22 of elastomeric plastics material, having a pair of conically tapered skirts 84, 88, slidably mounted on a valve stem 56 of a discharge valve 24, the stem 56 being fixedly connected to a plunger rod 14 having a discharge passage 16 therein. A spring 20 acting between the bottom of the pump cylinder 10 and the discharge valve 24 urges the plunger rod 14, piston 22 and discharge valve 24 to their upper position in which position the lower piston skirt 88 and a lower piston sleeve 90 co-operate with an annular wall on the discharge valve 24 to prevent liquid, which can pass through peripheral openings 64 in the discharge valve 24, from entering the annular space 26 which is formed between the piston 22 and the valve stem 56 and communicates with the discharge passage 16. In this position the upper piston skirt 84 engages between two concentric shoulders depending from a collar 36 having an opening 38 for the plunger rod 14, sealing this opening 38 from a breather chamber 40 having a vent 42. Upon depression of the plunger rod 14, the stem 56 first moves down relative to the piston 22 opening the space 26 to the pump cylinder 10, then when the lower end of the pistonrod 14 engages a shoulder 76 on the piston 22, the latter is moved down allowing the breather chamber 40 to communicate with the atmosphere via the opening 38, thus enabling a quantity of liquid to be dispensed. When the plunger rod 14 is released, the spring 20 acts on the valve 24 to close the discharge passage 16, the breather chamber 40 remaining open until the plunger rod 14 reaches its fully raised position enabling a further charge of liquid to enter the pump cylinder 10. The piston 22 is symmetrical about a central transverse axis to facilitate assembly. A cap 92 may be fitted over the plunger rod 14 for transportation and when not in use.

Abstract: 1289071 Boots &c FORTUNA-WERKE MASCHINENFABRIK AG 19 April 1971 [8 May 1970] 24488/71 Heading A3B In a shoe making machine of the kind in which a last 10 mounted on a support 2 is advanced in a longitudinal direction below a tool and is tilted about a longitudinal axis Q-S, the drive means for tilting the support 2 is connected to the support 2 by an engageable and disengageable coupling Kpl, the coupling Kpl being disengaged when a control member RO contacts the last bottom to allow the control member to align the initial position of the last 10. As described the last support 2 is mounted on a carriage 1 which can be reciprocated in the direction of arrow P by a chain drive 14. The last 10 moves below a tool, e.g. an abrasive band 16, which is mounted in a tool head 9 which can move heightwise in the direction of arrow N, the tool head initially being supported by a roller 1 on the head 9 engaging a guide 8 on the last support 2. The last 10 is supported by a last pin 4 mounted on a frame 3 which can tilt about axis Q and a toe support 5 which can tilt about axis S and which can be raised by solenoid 6 to clamp the last 10 against the pin 4. The toe support 5 can be adjusted in a longitudinal direction by spindle 19 and is connected to the frame 3 by a fork 17 so that the toe support 5 tilts with the heel support. During the advance of the last support 2 the support is tilted by drive means (not shown) connected to the support 2 by coupling Kp1 to align the last bottom with respect to the tool 16. The machine includes a control member RO consisting of a frame pivoted to the carriage 1 at M, a handle H pivoted to the frame at V and a contact member 20. Movement of the control member RO operates the various switches that control the machine. In operation a last 10 is placed on the support 2 with the control member RO in its initial position O (Fig. 2). Movement of the control member RO to position I causes the toe support 5 to be raised to clamp the last in the support 2 and disengages the coupling Kpl so that the last 10 is free to tilt. The control member is then moved to position II where contact member 20 engages the last bottom to tilt the last 10 so that it is correctly aligned with the tool 16. The handle H is then moved to position III which causes the coupling Kp1 to be re-engaged so that the last is held in its correct angular position. The control member RO is then moved back to position O and as it passes through position I the main drive is started to advance the carriage 1 so that the shoe bottom is roughened by tool 16. When the carriage 1 returns to its initial position switch Z is operated to release the last from the support 2.
