Abstract: 338,431. Haddan, R., (L. C. L. Corporation). Jan. 17, 1930. Vehicles with removable bodies.-A goods container adapted to rest upon a supporting surface such as the floor of a freight car or on shelves therein or on a station platform is provided with a door having a locking device which is maintained in the locked position so long as the container rests on the support, but is automatically released to allow the door to be opened when the container is lifted. In the construction shown, the locking- means comprise upper and lower locking-bars 16. 15 operated from a single, handle 12, an extension 41 of the lower bar having a notch 43 which is adapted to be engaged by the nose 29 of a looking-dog 27 secured to a shaft 24 rotatably mounted in brackets 25, 26 disposed between the floor 2 of the container 9 and the supporting surface. As the container is being lowered on to the support, the dog 27 contacts with the latter, rocking the shaft 24 and placing the nose 29 in its locking position so as to prevent opening of the door 10 ; the dog is weighted at 28 so as automatically to release the bar 41 when the container is again lifted. In order to allow the door to be locked while the container is on a support, the shaft 24 is movable laterally in slots in the brackets 26 against the action of return springs 37, thus permitting the bar 41 to be forced home with a snap action of the locking-dog 27. For operating the dog 27 when the container rests on shelves 45, Fig. 2, or similar end supports only, the shaft 24 is extended to the edge of the container and provided with an auxiliary weighted dog 31 designed to contact with the shelf 45 and so actuate the locking-dog 27.

[Also in Group XXIX] Apparatus for pressure testing a cock 18, Fig. 4, comprises a pivoted beam 13 carrying a fixed jaw 14 and a movable jaw 15, the latter jaw being operated by a piston in a cylinder 17b through a hollow rod 16, for gripping the cock therebetween and sealing opposed ports 18a. Testing fluid, e.g. compressed air, is introduced into the cock through the rod 16 and a valve mechanism 22, Fig. 2, controls the gripping of the cock and the immersion of the beam in a tank 11. A cap 26 is provided for sealing an opening in the top of the cock and is adjusted by a piston in a cylinder 29b subsequent to the gripping of the cock. The beam is raised and lowered by a piston in a cylinder 19a and connected by a chain 20 to a sprocket 21 on an axle 12 which carries a cam 30 adapted to co-operate with the stem 31a of a sequence valve 31. When the cock is held against the jaw 14, the valve mechanism 22 is operated first to actuate the jaw 15 then to initiate the dipping of the beam and the adjustment of the cover 26, the valve mechanism being so arranged that the cover 26 is adjusted before the beam is immersed. As the beam pivots, the cam 30 actuates the valve 31 to supply the testing fluid. On completion of the test, the controls of the valve mechanism 22 are returned to their initial positions and the valve 31 operates first to cut off the testing fluid, then to actuate the piston in the cylinder 19a to raise the beam and finally to actuate the pistons in the cylinders 29b, 17b to release the cock. As the beam rises, the cam 30 actuates the stem 31a to reset the valve 31. One or more of the valves in the mechanism 22 may be adapted to pedal operation. Specification 651,850 is referred to.

Title: Stabilized variable oscillator system
IPC: H03L7/20
Filed: 1957-01-23
Abstract: 813,074. Automatic frequency centrol systems. COLLINS RADIO CO. Jan. 23, 1957 [June 27, 1956], No. 2507/57. Class 38 (4). [Also in Group XL (c)] Relates to means for continuously stabilizing the output frequency of a variable-frequency oscillator by means of harmonics from a crystal-controlled source. As shown, a variable oscillator 110 is tunable in ten steps by a firstorder knob 151 which also controls a tunable circuit 117 to select an appropriate harmonic derived from a crystal oscillator 116. The outputs of the circuit 117 and the oscillator 110 are applied to a mixer 118. A discriminator 123, which is tunable by a second-order knob 152 receives the output from the mixer 118 and provides a voltage whereby the tuning of the oscillator 110 is controlled via isolation means 126 and regulator 111 which may be a saturable reactor tuning element. This portion of the system is known. The second-order knob 152 also adjusts a tunable circuit 133 to select a desired harmonic from a spectrum generator 132 controlled by a frequency divider 131 which receives the output of crystal oscillator 116 and divides it by ten. A second mixer 134 receives the outputs from the circuit 133 and the amplifier 122 in the first-order section and the difference frequency is applied via a gate circuit 138 (see Group XL (c)) to a second discriminator 142, which is tunable by a third-order knob 153, to provide a voltage to control the frequency of the oscillator 110. As long as the discriminator 123 is supplying an output above a predetermined threshold level the gate circuit 140 is blocked. Below this level the gate circuit is opened and allows the operation of the discriminator 142. The output of a second frequency divider 181, which divides the output from frequency divider 131 by ten, is applied to a spectrum generator 182, and a desired harmonic is selected by a tunable circuit 183 which is controlled by the tuning knob 153. The output of the circuit 183 together with the output from the amplifier 141 is applied to a third mixer 184 and the output from the mixer is applied via gate circuits 188, 189, and amplifier 190 to a fixed tune discriminator 191, the gate circuits being controlled as for the gate circuit 138 by discriminators 123 and 142 respectively. The discriminator 191 also receives an input from the frequency divider 131 which is first frequency compared and then phase compared with the input from the amplifier 190 to provide an output which finally adjusts the oscillator 110.
