Abstract: 1375950 Machinery guards 11 Oct 1972 [11 Oct 1971] 46997/72 Heading F2J A safety guard 10 for the discharging orifice 12 of a rotary lawn mower permits attachment and/or detachment of a grasscatcher whilst the guard 10 is in position covering the discharging orifice 12 to protect the operator and/or bystanders, and, when the grasscatcher is fitted, is adjustable to open or seal off the grasscatcher to the discharge orifice 12. As shown the guard 10 comprises a generally flat plate 11 manually adjustably pivoted on the mower at 18a by a handle 20 and has a separate flap 21 pivotally mounted at the lower edge of the plate 11 and maintained generally coplanar therewith by a torsion spring rod 26. When the grasscatcher is fitted the flap 21 is resiliently deflected by a protruding lip 30 on the grasscatcher. In this condition the flap 21 engages the lip 30 to seal off the grasscatcher. By turning the handle 20, the plate 11 is pivoted about 18a whereby the lip 21 may open the discharge orifice 12 to the grasscatcher. When the grasscatcher is removed from the mower the lip 21 seats against an abutment formed by the rear wheel axle 13 to hold the guard 10 closed against the air blast &c. from the discharge orifice 12. In the alternative embodiment of Fig. 3 (not shown), the pivoted guard is replaced by a similar flat guard slidable up and down within guides on the mower for manual opening and closing of the guard.

The plug 120 is formed with a lens portion 126 providing a shoulder 130a which seats against the outer face of the shoulder 104 when the plug 120 is pressed fully home in the blind bore 110 of the member 100. A light emitting device, e.g. light emitting diode 116 is mounted by a bush 114 in a second blind bore 112 in the lower end of the member 100, the emitted light therefrom passing through the transparent or translucent portion 118, between the ends of the blind bores 102 and 112, the lens portion 126 of the plug 120 acting to transmit and uniformly disperse the light from the device 116. In the alternative embodiment of Fig. 3 (not shown) the plug (120<SP>1</SP>) is formed as a hollow metal tubular member into which is fitted a cylindrical lens (146) and a shroud or other light directing means (not shown). In Fig. 4 (not shown), the cylindrical plug (12011) is additionally formed with an annular protrusion (150) which, when the plug is fully assembled as above, is arranged to be in the plane of the chassis 108 to improve sealing between the member 100 and chassis 108. In Fig. 5 (not shown) the flexible annular member (100<SP>1</SP>) is formed as a simple flanged annular cylindrical bush, i.e. the bore in which the plug 120 is fitted is simply formed as a through bore.

Filed: 1971-10-12
Abstract: 1327132 Transistor amplifiers THOMSONCSF 12 Oct 1971 [13 Oct 1970] 47526/71 Heading H3T A transistor amplifier 3 receives an amplitude modulated signal at 11 and a D.C. supply at 8 which varies as a linear function of the modulating voltage, in order to reduce power dissipation in the amplifier transistors. The input signal from a coupler 2 goes to both the amplifier 3 and a peak detector 6 whose output is amplified at 7 to provide the D.C. supply 8; and a feedback circuit 20 compares the D.C. supply 8 with the peak value of the output signal 9 to control the gain of amplifier 7 to compensate for frequency and temperature variations. Amplifier 7 may be a class D amplifier. The difference between the supply voltage 8 and peak collector voltage due to the carrier is thus kept constant to reduce collector dissipation.

The falling of the tube mouth is controlled by a guide 16 having an aperture 17 through which the tube falls on to the conveyer or by a brake for rollers 9, 10 which guide the tube over the mandrel. Air channels are provided on the outside of the mandrel and the bottom of the mandrel may be made of perforated metal or porous ceramic to permit passage of air into the tube beneath the mandrel when in the filling position to prevent a suction effect hindering the passage of the tube over the mandrel when in the upside down position.
