Title: Improvements in liquid shock-absorbers
IPC: F16F9/14
Filed: 1922-09-07
Abstract: 207,288. Agnelli, C., and Fazio, v. Sept.. 7,1922. No Patent granted (Sealing fee not paid). Fluid-friction vibration-dampers. - A liquid shock-absorber, especially for use with vehicle suspensions, comprises a cylindrical box 1 with its interior divided into compartments of variable capacity by a partition 10 fixed to the box and a vane 12 capable of rotating relatively to the box and carried by a disc 6 mounted in the mouth of the box in such a manner that an intermediate space is formed between the disc and the cover 3 of the box. As shown in Fig. 1, the box 1 and the spindle 7 of the disc 6 are secured to arms 2, 8 secured respectively to the axle and frame of the vehicle. The partition 10 and vane 12 have holes 11, 13 each variable in size by adjustment of a plate 16, and the hole 13 is provided with a spring-pressed valve 14. The box is filled with liquid through a hole closed by a screw plug which is adjustable to vary the initial pressure, or the pressure may be adjusted by screwing down a cap 5, or the spindle of the disc 6 may be screwed in a plug in the cover. On movement of the axle toward the vehicle frame, the vane. is moved and liquid passes from one compartment to the other through both holes 11, 13, while on the rebound the valve 14 remains closed and liquid passes through the hole 11 only. Liquid forced to the space between the disc 6 and the cover 3 is sucked into the compartment of which the size is increasing, thus tending to prevent leakage. In a modified form, both the valved and the open hole are provided in the fixed partition, the holes are adjusted in size by screwed plugs accessible from the outside of the box through plugged apertures, and the box is provided with a tubular member with a screw cover and a ball valve whereby liquid may be forced under pressure into the box, which is adapted to be secured to one of the relatively movable parts of the vehicle. In another form with adjustable or open holes 11, 13, Fig. 6, in the partition 10, the vane 12 has a through passage 29<1> closed at each end by a spring-pressed valve and communicating by a passage 31 with the space between the disc 6 and the cover 3, so that liquid forced into this space is sucked through the passages 31, 29<1> and past one of the valves into the compartment of increasing capacity.

Title: Improvements in or relating to a frequency sythesiser
IPC: H03L7/23
Filed: 1969-05-14
Abstract: 1,245,884. Frequency synthesizers. ADRET ELECTRONIQUE. 14 May, 1969 [16 May, 1968; 18 June, 1968], No. 24644/69. Heading H3A. In a frequency synthesizer of N decades, the first P decades are formed in a single unit which comprises an oscillator 2, a variable divider 5, means for generating a standard frequency, means 7, 8 for dividing said standard frequency, and a phase comparator 6 for comparing the outputs from the dividers 5, 8 to provide a control signal for adjusting the frequency of the oscillator 2. As described, the divider 5 may be varied to adjust the oscillator over the range 2.0000-2.0999 MHz and thus provides the first three decade ranges. To provide the next decade range, the output from the oscillator 2 is fed to a divide-by-ten stage 16. The output from which is mixed with that from a further oscillator 10 which is in turn frequency controlled by a variable divider loop 11, 13. Similar stages are provided for the other decade ranges. The unit of Fig. 2 may be modified to include a divide-by-nine stage in either the variable divider or in the standard frequency divider, Figs. 4, 5 (not shown). Phase comparator. Fig. 6. One of the two signals is applied as a square-wave to the base of transistor 29 which switches on and off the discharge and charge capacitor 42 in a sawtooth manner. The other signal is differentiated to provide a short pulse at the base of transistor 35 which clamps the charge potential on capacitor 42, and opens gate 39 to transfer the charge to capacitor 40. The level of the potential on capacitor 42 when the gate opens is dependent on the phase difference between the two signals.

Title: Electronic musical scale generator
IPC: G10H5/06
Filed: 1972-05-25
Abstract: 1384013 Electrophonic musical instruments; frequency dividers ITT INDUSTRIES Inc 25 May 1972 [1 June 1971] 24693/72 Headings G5J and G4A The twelve notes of an octave are derived from a master oscillator G by means of frequency converters. Each group of four converters (Fig. 1) produces four notes at threesemitone intervals. The input frequencies for the three groups are at semitone intervals. Each converter (Fig. 2) produces an output at N/Z of its input frequency to drive the next converter (if any) and a second output at I/Z of its input frequency which, when appropriate, feeds a divided-by-four circuit to give the desired note. Each converter comprises two digital counters DZ1, DZ2. For every Z input pulses counter DZ2 feeds (Z - N) pulses to counter DZ1 which delivers a single pulse to the second output line. The (Z-N) pulses are also fed to a gate A which prevents (Z - N) of the Z input pulses from reaching the first output line, which therefore carries N pulses per cycle of operation. Because Z/(Z - N) lies between two integers, counter DZ2 is made to count to each of these two integers in turn, in a pattern determined by a control stage St according to the state of counter DZ1, to give the correct division ratio on average. Because one output carries a string of pulses with gaps the outputs of subsequent stages show jitter but this is less than in a prior art arrangement comprising twelve converters in cascade.
