Patent GB-217365-A (GB)
Title: Improvements in means for tipping bodies on vehicles
IPC: B60P1/32
Filed: 1923-04-06
Abstract: 217,365. Lloyd, G. E. April 6, 1923. Tip-wagons.-In vehicles in which the body is caused to slide horizontally on the chassis to the tipping position and is then tipped the tipping is accomplished by sliding the body over the chassis by shortening an extensible pair of kinematic elements such as a screw and nut, cylinder and piston, rack and pinion, &c. or series of such pairs such as a " lazy tongs " device, locking the body to the chassis in its tipping position, and then tipping by lengthening the same pair of kinematic elements. Figs. 1 and 2 show a vehicle arranged for tipping to either side and employing a screw 6 and nut 8 as the pair of kinematic elements. The body is mounted on rails 1<a> and adapted to slide in a tipping frame 2 by the shortening of the screw and nut elements 6, 8 caused by rotating the nut 8 by a shaft 27L, disc 28, dogs 29, and bevel-wheels 26L, 26. The body slides to the tipping position on rollers 4 secured to the chassis and is then locked in the tipping position by the engagement of body bolts 11, 12 with apertures in the rails 1<a>, the arrangement being such that if the bolts 11, 12 are not properly engaged, catches 13, 14 are not released and so prevent the tipping of the body. The catches 14 are pivoted so as to clamp the body to the chassis in travelling. The screw is then extended and causes the tipping frame with the body to tip as shown in Fig. 1, the tipping frame not being slidable relatively to the chassis and engaging the latter by means of stops or pivots 18, 19. On return to the horizontal, the body bolts 11, 12 are automatically released, so clamping the tipping frame 2 to the chassis and permitting sliding of the body. In order that the body may be tipped to either side, the screw and nut with the bevel-wheels are mounted on a turntable 20 in the chassis, and when a eye 6<a> on the screw is released from a pivot pin 17R, the screw-and-nut pair is shortened and swung round to engage the other pivot 17L pivoted rods 36R, 36L being employed to prevent the screw from rotating with the nut in lengthening and shortening. Fig. 14 shows an arrangement wherein, in addition to side tipping, the vehicle is adapted for end tipping. The body is provided with rails 1<b> at right angles to the rails la, the rails 1<b> sliding or running in rollers 4RL mounted on the chassis and carrying rollers 4FL bearing on the chassis members 3. The rails 1<a> are lifted clear of the rollers 4RL, or these rollers are provided with flats on their flanges to enable the body to slide to the rear.

Title: Improvements in or relating to travelling wave amplifiers
IPC: H03F7/02
Filed: 1959-03-20
Abstract: 893,082. Parametric amplifiers. WESTERN ELECTRIC CO. Inc. March 20, 1959 [March 26, 1958], No. 9701/59. Addition to 850,036. [Class 40 (9)]. The constants of the travelling wave parametric amplifier described in the parent Specification are arranged so that amplification takes place when the frequency S of the signal applied by generator 5, Fig. 1, to line 1 is greater than the frequency P of the pumping wave applied by generator 9 to line 3. In effect, the modulation product (S - P) produced by the non-linear coupling inductors 8 is amplified, the pumping, signalling and idling frequencies being related by the equation P=(S-P)+(2P-S) the line 2 being arranged to support the idling frequency (2P - S). The amplified signal (S - P) may then be demodulated by the pumping frequency P to produce an amplified version of S. As in the parent Specification the variable coupling reactors may be capacitors. By using a number of idling frequencies the signal frequency may be made much greater than the pumping frequency. The signalling frequency S, the pumping frequency P and idling frequencies Q, I1, I2, &c. must satisfy the relations and the phase constants must satisfy the relations A reactance tube or a reverse biased P - N junction semi-conductor diode may be used as a variable capacitance. In a modification, the pumping wave may be transmitted by generator 79 along a circular waveguide 73, Fig. 3. Pairs of conductors 71a, 71b and 72a, 72b provide paths for the signal and idler waves, the signal being generated at 75. The waves are coupled by a body 70 of ferrite material wedged in the guide. The idler conductors 72a, 72b are supported by the ferrite material and the signal conductors are supported by foam plastic material 74. A filter 76a stops either the idler wave S - P or the signal S. Magnetic poles N, S on opposite sides of the waveguide bias the ferrite. Filters may be used to stop unwanted modulation products. The pumping wave may be fed back from the output to the input to avoid waste. Specification 839,596 also is referred to.
