Filed: 1971-12-07
Abstract: 1368454 Electrets MARCONI CO Ltd 7 Dec 1971 [16 Dec 1970] 56651/71 Heading H1M In a method of manufacturing an electret, a polymer foil 4 is supported in a chamber so as not to be in direct physical contact with it and is bombarded by low energy, e.g. 3 KeV, electron beam 1 normal to its major surfaces, the major surface remote from the bombardment being maintained in electrical isolation from the chamber. Optionally a conductive mesh 7 may be located between the beam source and foil, electrically connected to the anode, e.g. via back plate 5. This gives an enhanced charge in the electret for a given beam energy. The foil, e.g. fluorinated ethylene propylene, may be supported on a ring or frame mounted on insulators or by tensioning, e.g. a continuously moving web. Preferably the chamber is not evacuated and may contain air at about 10<SP>-5</SP> Torr. The formed electret may be metallized, e.g. by vapour deposition.

A rock drill comprises a hollow spindle 6, rotated by an electric motor 1, through a reduction gear 2, and a pinion 11, and fed by two hydraulic rams 4. The non-circular drill rod 7 is rotatable by a chuck 12 secured against relative axial movement to the spindle at 13, and is secured to a block 24 screwed into the bore 23 of the spindle. The spindle is mounted in a cross-head 5, and arranged for selective connection to the cross-head, or to the chuck, by clutch teeth 20, 21 or 15, 16. In operation, starting from the Fig. 1 position, the crosshead and rod 7 move to the left until the latter abuts the rock face. The advance of the drill and chuck ceases, the chuck is disengaged from the cross-head, and is engaged with the spindle by teeth 15, 16. The spindle and rod are rotated so as to drill the rock, until the rod moves through the full travel of the rods 8. The crosshead is retracted to the Fig. 1 position, and spring 22 displaces the chuck, so that teeth 20, 21 are again engaged. Chuck 12 cannot rotate and therefore block 24 is screwed along the spindle with rod 7 which remains in the hole. The rods 8 are again fed so that the rod 7 penetrates into the rock a further depth equal to the feed of rods 8. After the hole has been drilled to full depth, cross-head 5 is retracted, and the direction of rotation of spindle 6 is reversed, block 24 is screwed into the spindle and retracts the rod 7.

Title: Reproducing apparatus for a disc type record medium
IPC: G11B19/28
Filed: 1973-12-20
Abstract: 1435969 Automatic speed control SONY CORP 20 Dec 1973 [28 Dec 1972] 59088/73 Heading G3N  The speed of a record player turntable is automatically varied in order to compensate for detected eccentricity between the record and turntable. As shown in Fig. 1, a pick-up arm 6 is supported on a rotary shaft 7 which turns as the pick-up head moves towards the centre of a record 4. The angular position of the shaft 7 is detected by a variable capacitor 10 formed by a fixed plate 10a and a movable plate 10b secured to the shaft 7. The value of capacitor 10 determines the output frequency of an oscillator 11, Fig. 2, connected through a detector circuit 12 to a high pass filter 13 which forms an input for a variable gain amplifier 15, the gain being determined by the output from a low pass filter 14. The output from amplifier 15 modifies the voltage from a reference source 17 in a circuit 16, the output from which forms an input for a conventional turntable motor speed servo-circuit 40. The actual motor speed is represented by the frequency of pulses from a generator 21 connected to motor drive circuit 20. In use, any eccentricity in the record or turntable produces a high frequency signal which is applied through the amplifier 15 to modify the setting of the servo-circuit 40. The gain of the amplifier increases with the angle of the pick-up arm 6 due to the action of the low pass filter 14, so that the greater effects of eccentricity near the centre of the record 4 are compensated. In another embodiment, Figs. 5-7 (not shown), the pick-up arm angle is detected photo-electrically using a variable radius shutter mounted on the shaft 7. A magnetic detection device may also be used.
