Title: Improvements relating to super-regenerative receivers
IPC: G01S13/76
Filed: 1945-11-30
Abstract: 604,717. Transponders. FERRANTI, Ltd., and WOOD, H. Nov. 30, 1945, No. 32486. [Class 40 (v)] In a transponder employing a super-regeneratively operated valve maintained at constant sensitivity, means are provided for deriving a potential directly proportional to the recurrence frequency of the received pulses, the potential being utilized to counteract any divergence from constant sensitivity consequent upon the reception of pulse trains having different recurrence frequencies. The output from superregenerative valve 1, fed with quench frequency oscillations from generator 7, is rectified by diode 15, the rectified output being applied to pentode 23 having a tuned circuit 25, 26 to reject the quench frequency component of the noise as described in Specification 591,965. The output is rectified by diode 30 and, after smoothing, applied to the grid of valve 36, the setting of potentiometer 53 providing the correct bias for valve 1 to give the required sensitivity. An incoming pulse signal causes the noise component to increase, thereby increasing the negative potential applied to valve 36, and reducing the potential drop across resistor 42. This fall in potential is offset by the rise in potential across resistor 53 due to the transmitting valve 58 being rendered conducting by the transmission of the pulse signal through amplifier 61 and cathode follower 69.

Title: Improvements in or relating to the shrinking of fabric webs or fleeces
Inventor: SCHLEGEL DIETRICH

Filed: 1958-10-11
Abstract: 879,483. Finishing fabrics; agglutinated fibrous materials. AUGSTEN, R. Oct. 11, 1958, No. 32527/58. Classes 42 (1) and 140. [Also in Groups IX and XIII] A damp woven or knitted fabric web or fibre fleece is shrunk by vibrating it as it passes through a drying zone, the amplitude of vibration imparted to the web or fleece progressively decreasing in the direction of feed and the supply of drying medium into and from the drying zone being controlled in inverse relation to the speed of the feed. The latter feature allows reduced rate of feed and simultaneous increase of drying effect when dealing with heavy fabrics. As shown, the web or fleece passes, between a feed roller 1 and a discharge roller 3, over a vibratory grid 2, drying air passing downwards through the grid. The feed end of the grid is oscillated on a guide rod a while the discharge end has a horizontal sliding motion only. A fibre fleece may be steeped in an agglutinating agent which is set to form a " non-woven " article. In an alternative arrangement, the drying air passes upwards through the grid and supports the web or fleece against the underside of the grid.

According to the invention, the guns are fired in groups or simultaneously, independently of the guns' displacement, by pedal mechanism on the trainable carriage. This mechanism operates a, push-rod 149 disposed in the trunnion 104 and thereby rotates a shaft 154 on the gun cradle, which shaft is connected to the triggers of the barrels to be fired. Further, the cocking levers 165, Fig. 5, of all the guns are simultaneously operated through toothed sectors 167, by rotating a common shaft 168 arranged parallel to the trunnion axis. To fire the centre guns 101, 101<1>, the gunner occupying a seat 124 depresses a pedal 139, thereby actuating a rack 144, sector 145, and shaft 147, to move the push-rod 149, which through a cam 151 and rod 152 rotates the firing shaft 154. To fire the outside guns 102, 102<1>, a second pedal is depressed and through similar mechanism operates a push-rod in the trunnion 104<1> and thereby rotates a separate firing shaft similar to the shaft 154. The sightbar 163 pivoted to the carriage above the trunnions is connected to an arm 162 on the cradle by a parallel-motion link 164.
