Filed: 1964-09-11
Abstract: <PICT:1046198/C6-C7/1> A method of electrolytic machining in which the workpiece is held in resilient contact with the electrolytic machining tool, either by use of a tool which comprises a flexible smooth rotating disc, or by mounting the workpiece on a carriage which is itself flexibly mounted and using a non-flexible smooth steel disc having a speed of rotation of 2,000 to 6,000 r.p.m. as the electrolytic tool.  In the embodiment shown a resilient spring-steel disc, rotatably mounted on shaft 2 within housing 3, is fed with electrolyte e.g. an aqueous solution of potassium nitrate and potassium nitrite, via tube 8, the electrolyte forming a film upon the disc and returning to a reservoir via the outlet 4.  The workpiece is mounted upon a holder 5 upon a carriage 6 which may be mounted upon a resilient mounting 7.  The workpiece is pushed against the disc to make electrical contact therewith via the electrolyte film thereon, the disc becoming thus deflected.  As metal is removed from the workpiece the disc resumes its original position, and the current drops until, when a prearranged current is reached, the workpiece is withdrawn.  In the example the workpiece comprises wire ended headers (Fig. 2, not shown) for use in the mounting of transistors or other semi-conducting devices.

Title: Friction clutch control system
IPC: F16D48/06
Filed: 1966-08-22
Abstract: 1,097,869. Clutch control. FORD MOTOR CO. Ltd. Aug. 22, 1966 [Aug. 30, 1965 (2)], No. 37515/66. Heading F2L. A vehicle clutch control system comprises an hydraulic servo 10 for effecting clutch release and under the control of a shift valve 32 and a pilot valve 60 which operates the shift valve 32 in response to a manual control 140 and a signal indicative of engine operating conditions, e.g. manifold vacuum, actuation of the manual control causing the shift valve 32 to connect the servo 10 with its pressure source for clutch release, and release of the control causing the shift valve to exhaust the servo for clutch reengagement at a rate dependent upon engine conditions. As shown, pressure liquid for the system is supplied by an engine-driven pump 20 and shift valve 32 is combined with a pressure-regulating valve 30. Pilot valve 66 is operated by a pair of vacuum diaphragm units 96, 98, the former of which is permanently connected by a line 132 to the engine manifold, while the vacuum line 134 for the latter unit is normally blocked by solenoid air admission valve 136 controlled by manual switch 140. To effect a gear-change switch 140 is closed to open valve 136 and connect diaphragm unit 98 with the engine manifold, pilot valve 66 thus being moved against loading springs 118, 120 to its extreme left-hand position 92 in which it permits pressure liquid in line 78 to move shift valve 32 and regulating valve 30 to the left, liquid at increased pressure then passing through lines 60, 18 to servo 10 to release the clutch. Upon completion of gear-change switch 140 is opened and pilot valve 66 moves to the right to position 94 in which servo 10 exhausts through a restricted orifice 86 to ensure slow re-engagement of the clutch. In the event of gear changing being made under high load torque, low manifold vacuum conditions, release of switch 140 results in pilot valve 66 being moved farther to the right, to the position shown, to uncover a drain port 88 so that rapid servo exhaust and clutch re-engagement results. Control is progressive between these conditions. In a second arrangement. Fig. 2 (not shown), the manual switch (136) actuates a solenoid (128) which controls the loading of a spring (104) for regulating the setting of the pilot valve (100).

Abstract: 1,017,651. Typewriters &c. SPERRY RAND CORPORATION. Oct. 11, 1962 [Oct. 18, 1961], No. 38476/62. Heading B6F. [Also in Division G3] In fluid control apparatus suitable for pneumatically operated typewriters &c., and comprising bi-stable fluid switches, switching of flow from one channel to another is arranged to take place in response to blockage of an outlet. Fluid passing from a pump or compressor 35 and pressure regulator 37 to a nozzle 19 normally discharges through a channel 9, due to the wall 15 of this channel being offset from the nozzle by a lesser amount than the wall 17 of a channel 11. When the outlet of channel 9 is closed by a finger placed over an orifice 39 in a keyboard &c. the discharge switches to the channel 11 to actuate an output device 42. The discharge is switched back to the channel 9 on removal of the finger from the orifice 39 by the action of a control jet 7 energized from the channel 11 or by a pulse produced by the device 42. In a modification, the control jet 7 is omitted and switching back is accomplished by closure of the channel 11 by a valve operated from the keyboard. In another modification, the channel 9, which has a return connection to the pump 35 instead of discharging at the orifice 39, contains a valve operated from the keyboard for producing the back pressure. All switches associated with a single keyboard may be switched back to their initial condition by a single control. The channel 11 may have a recess in which vortices are created to enhance the bi-stable characteristic. Keyboards comprising a number of switches may be constructed of laminations, all of the fluid passageways of one switch being formed in a single lamination.
