Title: Process for the preparation of anhydrous hydrazine
Inventor: GAUSSENS GILBERT
IPC: C01B21/16
Filed: 1966-11-10
Abstract: 1,137,210. Anhydrous hydrazine. COMMISSARIAT A L'ENERGIE ATOMIQUE. 10 Nov., 1966 [19 Nov., 1965; 7 Oct., 1966], No. 50423/66. Heading C1A. Anhydrous hydrazine is prepared by irradiating liquid ammonia containing acetone. The concentration of acetone may be between 0À01 and 2 moles per litre and at least one hydrogen atom intercepter in addition to the acetone, such as tertiarybutanol, triphenylmethane or chlo - roform, may be present. Suitable radiation sources'are X-rays, electron beams and gamma-rays from nuclear reactors; intensities of 10- 80 Megarads/hour and doses of 100,000-600,000 rads are suitable. Fig. 3 shows a plant in which in section 10, NH 3  is treated with sodium to remove impurities such as A 2 O, O 2  and CO 2 , distilled, liquefied, and mixed with the interceptors in mixer 14 before being passed to the irradiation loop 20. The irradiation is carried out in the cylinder 21, maintained at 86‹ C, with an electron beam, the liquid being recirculated through the cylinder and through a reservoir 24 in which the gases, N 2  and H 2 , formed are separated. The liquid, after irradiation, is withdrawn and cooled to -78‹ C. by the two heat exchangers 31 and 32 and the interceptors, which are thus crystallized, are separated in the decanter 33. The mixture of liquid NH 3  and hydrazine is then separated by distillation at 32‹ C. in the columns 34 and 35 using heat provided by the water, which is heated by transfer with the irradiated ammonia in heat exchanger 31, and the NH 3  is recycled.

A stereophonic pick-up comprises two cantilever piezo-electric transducer elements 1, 2 (Fig. 1) or 10, 11 (Fig. 2) mechanically loaded by a single stylus holder 4 or 12. An end 6 of the stylus holder 4 or 12 bears against the main surfaces of the elements 1, 2 or 10, 11, which main surfaces are at least approximately perpendicular to one another. The elements 1, 2 or 10, 11 are "benders" and the end 6 has, in the two directions perpendicular to the main surfaces of the elements 1, 2 or 10, 11, at least locally equal dimensions so that the stylus holder 4 or 12 is simultaneously tangential to the longitudinal axes of symmetry of both main surfaces at the cantilever ends of the elements 1, 2 or 10, 11.

The central portion of the stylus holder 4 comprises a pair of plates 7, 8 between which is fitted a flexible mounting plate 9 allowing the stylus 5 to move in all directions. In the pick-up of Fig. 2, the longitudinal axes of symmetry of the elements 10, 11 are at an angle, but the free ends are closely spaced. The stylus holder 12 extends between the elements 10, 11, providing a compact arrangement. The stylus holder 12 has two collars (20, 21), Fig. 3 (not shown), between which is disposed a mounting plate (22) secured in a pick-up housing.

Title: Improvements in and relating to systems for controlling fluid flow
Inventor: NEWBERRY JOHN CUTHBERT
IPC: G01P13/00
Filed: 1967-11-16
Abstract: 1,254,423. Fluid-pressure servomotor systems. NEPTUNE MEASUREMENT Ltd. Feb. 14, 1969 [Nov. 16, 1967], No. 52172/67. Heading G3P. In a fluid-flow control system, for liquids such as whisky and oil, where a meter failure may cause loss of revenue a pneumatic timing device 16, 18 provides an output signal for an actuator 32 to stop the flow when the frequency of signals corresponding to the flow-rate falls below a predetermined value. The signals are generated by a valve 10 reciprocated by a cam on the first index wheel of a mechanical meter and are applied alternately to two timing valves 16, 18 which permit the signal to pass to an output line 29 only when the signal has been applied for more than an adjustable pre-set time to the valves. The actuator 32 closes a valve 34 to stop the flow when it receives a signal through a spring return valve 30 from the line 29. To start the flow, a reset button 36 supplies air through a valve 38 to the valve 30, which connects the signal output line 29 to exhaust 42, and to an actuator 44 for the valve 34. Air is also supplied through a timing valve 46 to an actuator 48 of the valve 38 which connects the valve 30 to exhaust if the operator attempts to hold the valve 34 open by holding down the reset button 36 when a signal is present in the line 29. To reset the valve 38 and reconnect the button 36 with the system, a further button 52, operable by a key or located in a position accessible only to authorized personnel, is depressed. The buttons 36 and 52, the timing valve 46 and the valve 38 may be replaced by a spring return push button valve 20 which resets the system by connecting the line 29 to exhaust and the actuator 44 to the air supply. A further embodiment prevents any flow which might be obtained by successive operation of the button 36 which also supplies air to a further timing valve. This closes after a longer interval than the valve 46 and resets the latter and the button 36 if no signal is present in the line 29. If a signal is present, the further timing valve is disconnected before it has had time to operate and the system has to be reset by the push button 52.

Title: Crossfeed gating system for borehole logging systems

Filed: 1969-11-04
Abstract: 1282619 Borehole logging MOBIL OIL CORP 4 Nov 1969 54017/69 Heading H4D In an acoustic borehole logging system using a transmit/receive transducer, transmission energy crossfed into the receiver channel is attenuated by passing the received signal through a first time gate controlled to block the transmission energy, amplifying the gate output, which output includes residual transmission energy, and passing the amplified signal to a second time gate controlled to block the transmission energy. This overcomes the effect of imperfect blocking by the first gate, and the width of the second gate can be set to gate out spurious signal spikes caused by the first gate. The invention is applicable to bore hole logging with a rotating transducer feeding an uphole cathode-ray tube display whose trace is photographed to give a pictorial log of the borehole. In the Fig. 1 embodiment, master timing pulses from oscillator 20 close normally-open gates 34, 40 during transmission by transducer 30, the transmission being delayed by monostable circuit 22 to allow the gates time to close. Echo signals received by transducer 30 pass through gate 34, amplifier 36, gate 40 and a second amplifier 42 to a detector circuit 44 which derives the signal envelope for application via cable driver circuit 46 to the logging cable and hence to the uphole equipment. In an alternative embodiment (Fig. 5, not shown) the gates are normally closed and are opened only after the acoustic transmission pulse has ended. Details of the Fig. 1 circuits are given.
