IPC: E01B27/16
Filed: 1980-10-29
Abstract: In a railway track ballast tamping device, a tamping unit is carried for vertical adjustment by a support mounted on the frame structure of a vehicle and comprises at least one pair of jointly-operating tamping tools crossing each other. The arm of these tools are adapted to pivot on opposite eccentric cranks formed on an eccentric shaft rotatably mounted in a bearing rigidly fastened to the support; the upper ends of the arms, opposite the pick-forming thereof, are each pivotally connected to a hydraulic cylinder inclined not in excess of 30 DEG  to the vertical; the planes passing through the axis of rotation on the eccentric shaft and the center of the opposite eccentric cranks thereof form between them an angle of 40 DEG  to 80 DEG  in order to warrant a symmetrical, synchronous oscillatory motion of the packers carried by the lower ends of the picks. To prevent the transmission of detrimental vibration to the support during the rotation of the eccentric shaft, there are provided, in addition to out-of-balance weight carried by a flywheel rigid with the eccentric shaft, balance weights fastened to the hydraulic cylinders and disposed above the level of the pivotal connections between these cylinders and the support. Furthermore, the tamping tools of a pair disposed on the same side of a tie have their upper ends rigidly interconnected.

Inventor: WALT HANS
IPC: E04C1/40
Filed: 1975-09-09
Abstract: The lightweight structural element consisting of expanded clay material has a basic body (2) which is of relatively low density and through which a supporting structure (3) of greater density passes. In order to improve the strength characteristics and the capacity for reproduction thereof, the supporting structure (3) contains approximately mutually parallel supporting members (4a, 4b) which extend between two opposite sides (5, 6) of the lightweight structural element (1a, 1b). An advantageous process for producing the lightweight structural element consists in arranging a blank (9a, 9b, 9c), having approximately mutually parallel cavities (11a, 11b, 11c, 11d) running between two mutually opposite sides (5, 6), in a mould (10), closed on five sides, such that in each case one opening of the cavities is exposed. Into these openings there is blown in each case a hot-gas stream (14) at such a rate and temperature that the blank (9a, 9b, 9c), beginning at the side remote from the blowing-in side and finishing at said blowing-in side, begins to sinter, expands and seals at least partially. <IMAGE>

Title: Hydraulic pressure pulse generator
IPC: B05B12/06
Filed: 1969-10-31
Granted: 1971-07-09
Abstract: Pressure impulses are produced in a liquid in a device comprising a cylinder and a reciprocating piston moving inside it which divides the space of the cylinder into two chambers, one of which is in communication with compressed gas, whilst the other is filled with liquid and has an opening for the flow of the liquid under pressure resulting from the shock action of the piston which is propelled by the compressed gas of the first chamber. On the face at the end of the cylinder on the side of the first chamber are suction and discharge valves. The suction valve connects the first chamber with the atmosphere whereas the piston movement at the side of the second chamber and the discharge valve connects the first chamber with the compressed gas during the return movement of the piston. Means are provided for closing the pipe connecting the compressed chamber with the first chamber when air is admitted to it from the outside. Use: splitting rocks, hydraulic metal stamping and cutting.
Patent FR-2045346-A5 (FR)
Title: Ozoniser
IPC: C01B13/11
Filed: 1970-04-16
Granted: 1971-02-26
Abstract: The device consists of two concentric coils with an air gap between them in which the discharge takes place. The potential difference between each pair of opposing points is the same. The discharge is limited by being in series with inductances and uniformity is achieved by coupling the inductances. The discharge is struck by applying A.C. potential to the terminals of the coils which are connected in series. The device is improved if the coils are placed in a magnetic circuit in which case the discharge can be brought about by applying A.C. to a primary coil in the same circuit.

Title: Flax fibre hank package - in which hanks hang from coiled tape is automatically unwound
IPC: D01B5/00
Filed: 1970-08-05
Granted: 1972-04-07
Abstract: The package also has a tying yarn wound around its middle region, and is supported around a spindle on a platform whilst the tape and tying yarn are wound onto separate spools. The spools are driven at different rates by a common drive motor via gearing so that the tying yarn and tape are wound up at different rates to compensate for the difference in dia. of the package between the middle and ends, and thereby maintain the tape and tying yarn taught. The platform is pref. continuously braked to further maintain the tape and tying yarn taught, and a sensor plate continuously senses the leading hank during winding-off and deactuates the drive motor whilst the leading hank is removed. Winding-off is accurately controlled.

Abstract: 1387321 Speech synthesiser R T GAGNON 15 Feb 1972 [1 March 1971] 6966/72 Heading H4R In a speech synthesiser an 8 bit input signal is fed into a register 76, two of the digits are used to control the frequency of a voiced excitation function generator 14 while the remaining  digits are fed to a memory matrix 80 which converts the 6 bit signal into a particular combination of binary signals on its output leads. The output leads are connected to resistor adding networks 82a to 82j to provide a number of analogue control signals which control, in the synthesiser 18, the characteristics of the excitation signal, the frequency and amplitude of formants synthesised by the tunable filters 42, 44, 46, and the duration of a speech phoneme synthesised by the apparatus. The analogue control signals are generally applied to the synthesizer via low pass filters 84a to 84h, to make the transistion between phonemes smooth. As described, a resistive adder 82a controls an exponential function generator 86 to produce, when required, a step-function followed by an exponential decay which, when applied to analogue multiplier 30 connected to the noise generator 16, provides a modulation of the excitation function to generate a "plosive". A further adder 82d via a low pass filter 846 controls a chopper 92 which is fed with a signal from the voiced excitation function generator and also controls multiplier 30 to provide a pitch frequency modulation of the noise generator during production of a voiced fricative, such as "b" "z", &c. Resistive adders 82f, 82e, 82d, control the frequencies of respective filters 42, 44, and 46, via respective filters, 84f, 84e, 84d to provide formant frequency emphasis. Analogue multipliers 60, 64, and 27 provide control of the relative amplitudes of the formants and a background excitation function signal, according to the outputs of further adder networks, and an adder network 82j, via timing control 98, controls the duration of the phoneme corresponding to the input signal fed to register 76. A fixed resonant filter 69 at the output of the synthesizer provides a fourth formant corresponding to the natural resonant frequency of the nasal cavity in a speaker. Circuits are described for the various parts of the synthesizer.
