Title: Rate Modifier for a Machine Tool
IPC: B23Q3/157
Filed: 1966-09-08
Abstract: 1,157,667. Machine tool details. KEARNEY & TRECKER CORP. 8 Sept., 1966 [16 Sept., 1965], No. 40226/66. Headings B3B and B3K. [Also in Division G3] A machine tool comprises a pair of relatively movable members each of which is moved at a predetermined speed rate by a variable-speed transmission mechanism, a load-measuring device being actuated by a predetermined degree of load on one of the transmission mechanisms to reduce the speed rate of the other transmission mechanism through a rate regulator modifier which is disconnected by a separate control means after a predetermined operating interval. As shown, Fig. 1, a tool changing machine tool has a base 12 slidably supporting a horizontal saddle 13 on which slides a transverse work-supporting table 14. Mounted on the table 14 is an indexable work-table 17. A spindle head 24 is vertically movable by screws 30, 31. At the upper limit of travel of the spindle head tools are interchanged between a tool receiving spindle 46 and an indexable tool store 37 by a rotatable arm 48. The axes positioning controls 79, 83, 88, a spindle rate control 74, and a miscellaneous function and tool change control 69 are responsive to the outputs of an address register 65 determined by sequential command instructions from an input 62 controlled by the reading of a punched tape 59. The spindle rotation and axes movement are effected hydraulically under the control of solenoid valves. In the programmed control system, Fig. 3, the command instruction signals from the tape input 62 are fed to the function address 65 and distributed to the controls 79, 83, 88, 74, 69, completion signals from which initiate an advance of the tape by a unit 371. For the X axis control 88, shown in detail, programmed velocity and position commands are fed from the register 65 to input units 328, 358. The position command being set in a register 330 and compared, by a comparator 333, with an actual position valve in a register 335 responsive to pulses from a count control gate 339. The velocity command is fed to a buffer store 361 the output of which is adjusted by a feedrate modifier 364 and a manual override 367. The adjusted feed rate is fed through the count control gate, closed by the output of the comparator, to a command phase counter 320 determining the frequency of a resolver supply 343. The error signal from the resolver through a phase discriminator and digital analogue converter 325 operates a servo control valve 218 to effect the required directional movement of an hydraulic motor 230. The feed-rate modifier 364 is responsive to the actuation of a feed-rate modifier controller 115, comprising a pressure switch in an hydraulic feed line to a motor, to reduce the programmed feed-rate by a pre-determined amount. The modified feed-rate is maintained until the next end-of-block signal on the tape when the pressure switch is unlatched.

Title: Connecting units for flexible hand-spray hoses
IPC: E03C1/06
Filed: 1971-09-09
Abstract: 1338242 Shower supply connecting unit FINNISH VALVE CO Ltd 9 Sept 1971 [28 Aug 1970] 41414/70 Heading A4N A connecting unit for coupling a flexible handspray hose to a valve (not shown) comprises a chamber 2 having a water inlet 17 for connection to the valve, a water outlet 23 for connection to the hose 25, and within the chamber, a valve permanently biased into engagement with a seat in the wall of the chamber and arranged, in the event of suction developing in the chamber, for moving from the seat against the bias so as to admit air to the chamber. The base 3 of the chamber is formed with an air inlet adjacent an end 6. An externally threaded bush 9, with an outer flange 10, is screwed into a bore at this end, a sealing ring 11 providing a seal with the base. The inner end of the bush extends into the chamber and provides an annular valve seat on which the vertically-disposed valve sits. The valve comprises a disc 12 on a spindle 13 which is axially slidable within a guide 14. A sealing disc (15), Fig.2 (not shown) engages the valve seat and is held in contact with the disc 12 by a central screw 16. In normal use the valve is held on to its valve seat by the pressure of water in the chamber, and by its own weight, but should the pressure fall due to the handspray falling into a bath of water with a tap open at a lower level on the same water supply, then the valve is raised from its seat and air is drawn into the chamber through the air inlet. This reduces the suction and prevents water being siphoned out of the bath through the hose 25. Alternatively, the valve may not necessarily be adapted for vertical movement and/or may be otherwise biased towards its closed condition.

A signal transmission line for transmitting has a plurality of devices 11, 12, such as Gunn effect or like travelling field domain devices, biased below the threshold for nucleation of a domain but above the domain sustaining voltage, each device 11 is coupled between two sections of the signal transmission line and the biasing potential is applied to each device 11, 12 via respective subsidiary transmission lines ZB, ZB<SP>1</SP> having a different characteristic impedance from the section of line to which it is connected, such that when a pulse is applied which causes the threshold voltage to be exceeded a domain is formed in each device and an output pulse occurs across the load which is formed at least partly by the characteristic impedance of the signal transmission line. The output of the device 11 may be matched by an impedance transformer 17 to the next section of transmission line 13 which feeds a similar Gunn effect pulse regenerator 10<SP>1</SP>. The devices 11, 12 are connected in series with the transmission line and each give an output pulse of opposite polarity to the triggering signal. The devices 11, 12 may be connected in parallel with the transmission line (Fig. 2, not shown), to give an output pulse of the same polarity as the input trigger signal. In this arrangement, unidirectional element (20) is connected between the devices 11, 12 to prevent spurious signals travelling back and triggering a preceding device 11. Each regenerator 10, 10<SP>1</SP> may include a cascade of several devices having increasing domain propagation times. The bias for the devices may be D.C. with a varying component having the same frequency as the signal pulses so that the device is biased with the correct amplitude when a pulse signal occurs. The devices may alternatively be Read avalanche diodes or electroacoustic or field trapping effect devices.
