Title: Improvements in or relating to time switches
IPC: G04C23/16
Filed: 1949-04-08
Abstract: 669,062. Time switches. MIDGLEY, A. H. March 30, 1950. [April 8, 1949] No. 9587/49. Class 38 (v). A switch for controlling, e.g. a cooker, comprises cams 9, 13 co-operating respectively with an "off" switch 26 and an "on" switch 25. Cam 9 is fixed on a shaft 4 and is driven by an electric or clockwork motor 2 through gears 1 and a wheel 3 which is loose on the shaft 4, the wheel 3 driving the shaft through friction between the wheel 3, a wheel 5 fast on the shaft and a friction washer 7. The shaft carries a setting plate 15 having an aperture 15a through which is visible a scale on a plate 20 mounted on a spindle 12 surrounding the shaft, the cam 13 being fast on the spindle. The cam 13 is driven from shaft 4 over the plate 15, a pinion 18 pivoted thereon, and a gear 19 meshing therewith and fixed on spindle 12. The mechanism is set by manually rotating a scale 22 until the final switching-off time (i.e. the operating time of switch 26) is indicated against a fixed pointer 24. The cooking time (as shown by a scale on plate 20 co-operating with a "time" pointer on plate 15) is then set by rotating the plate 20 by means of the pinion 18 and gear 19, the pinion 18 having a knob 17 and passing through a slot in plate 20. This sets the cam 13 relatively to cam 9. Finally, plates 15 and 20 are rotated clockwise by knob 16 until the time pointer on plate 15 coincides with the time, as shown on scale 22, at which the setting operations are effected. This rotates cams 9 and 13, and closes switch 26 to start the motor 2, and opens the switch 25. The cams are then returned bv the motor, the switch 25 being closed at the start of the cooking time and the switch 26 opening at the end of the cooking time, i.e. when the "time" pointer coincides with the pointer 24 again. The scales and cams may be modified for use in a street lighting system, wherein the lights may be on for more, or less, than 12 hours. The cam follower 28 of each switch 25, 26 is adjustably secured to the contact-carrying spring 27 by a screw 29.

IPC: C04B35/65
Filed: 1987-09-15
Abstract: There is disclosed a method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of an expendable pattern (6). The method includes the steps of surrounding the expendable pattern (6) with a filler material (4) to thereby form a filled cavity within the filler material (4). The expendable pattern (6) is chemically or physically removed from the filler material (4) and a quantity of a parent metal is put into the cavity. The parent metal is heated to a temperature above its melting point and an oxidation reaction process begins whereby the oxidation reaction product infiltrates and embeds the surrounding filler material (4). Excess filler material and/or excess parent metal are removed, thus resulting in a self-supporting ceramic composite body having a cavity in the shape of the expendable pattern (6).
