Abstract: In a continuous process for the production of salts of cyclohexylsulphamic acid by hydrolysis of a reaction mixture containing cyclohexyl-ammonium - N - cyclohexylsulphamate, cyclo-hexylamine and water and using at least a stoichiometric amount of sodium hydroxide or calcium hydroxide, the reaction mixture and the metal hydroxide is passed downwardly through a packed column, steam is passed upwardly through the column and cyclohexylamine is removed in the distillate from the column. The term "stoichiometric amount" includes sufficient metal hydroxide to hydrolyse any cyclo-hexylamine sulphate present in the reaction mixture.  An apparatus for carrying out the process is described with reference to the drawing (not shown).

Title: Improvements in and relating to thermo-regulators
IPC: G05D23/02
Filed: 1923-10-03
Abstract: 227,158. Bishop, H. S. Oct. 3, 1923. Thermostats.-In a device for controlling the supply of a heating or cooling fluid, the temperature-sensitive member is of the kind comprising a number of elements formed of materials having different coefficients of expansion, and comprising a rod 1, Fig. 1. of silica &c. arranged within an open-ended tube 2 of similar material, around which is another tube 4 having a relatively larger coefficient of expansion, the whole being enclosed in a tubular element 8 also having a large coefficient of expansion. The upper end of the rod 1 bears on a lever 10, the outer end of which is in contact with the stem 13 of the valve which controls the supply of fluid. The valve comprises a chamber 15 having inlet and outlet passages 16, 17 and containing a fixed diaphragm 20 and a movable member 18 connected to the stem 13. The area of the chamber is considerably greater than that of a conduit permitting the maximum rate of flow of the fluid, and the total areas of the apertures in the diaphragm and in the movable element are each not substantially, less than the area of the passage leading from the valve chamber. The apertures 21 in the diaphragm are formed in concentric grooves 22, the elevations 23 between which form the seating surfaces, and the apertures 24 in the member 18 are also formed in concentric grooves 25, the elevations 26 between which are in register with the grooves 22. The member 18 is mounted on a threaded spindle 29 which can be turned by a wheel 36 to adjust the valve independently of the temperature-sensitive device, the member 18 being prevented from rotating by a pin 30 carried by the diaphragm and passing through an aperture in the member 18. In a modification, Fig. 3, the tube 8 is connected by a collar 43 to a tube 44 having a large coefficient of expansion and freely mounted in an extension 45 from the chamber 14. Within the member 44 is a tube 46 of silica &c. bearing at one end against the collar 43 and at the other end against the chamber 45, a spring 48 being interposed between a shoulder 49 on the tube 44 and the cap 50 of the chamber 45.

Title: Radio frequency dielectric induction well logging system
IPC: G01V3/28
Filed: 1976-02-15
Abstract: 1513595 Borehole logging TEXACO DEVELOPMENT CORP 15 June 1976 [21 July 1975 2 Sept 1975] 24702/76 Heading G1N In a method of determining the characteristics of earth formations 15 in the vicinity of a well borehole 13 having a conductive fluid 14 in it, in which an alternating electromagnetic field at a frequency in the range 10-60 MHz is generated from a transmitting coil 17 and detected at at least one receiving coil 19 spaced axially of the borehole from the transmitting coil, the formation of a continuous circumferential path of the conductive fluid about either coil is prevented by the provision of at least one radially-extending, non-conductive fin 101 extending from the logging sonde 11 to the borehole wall. This effectively increases the magnitude of electromagnetic fields from the transmitter coil into the formations and from the formations into the receiver coil(s). Preferably the formation resistivity is determined by measuring the amplitude of the r.f. signal (30 MHz) at one of the receiver coils. A resistivity measurement or the r.f. amplitude measurement is then related to the phase difference between received signals Figs. 4, 5 (not shown) at two axially spaced receiver coils 19, 21 receiving the 30 MHz signal to determine permittivity of the formations. In an alternative embodiment Fig. 8 (not shown) the apparatus combines a (16 MHz) radio-frequency dielectric logging portion with a conventional 20 kHz resistivity logging portion. The former uses a transmitting coil 17 and receiving coil 21 one metre apart. Fins (101) are provided about both the resistivity log receiving coil (111) and the radio-frequency log receiving coil to prevent the formation of circumferential conducting paths in the well fluid about the coils. The measured resistivity is compared with the ratio of the amplitude of the 16 MHz signal received at the coil 21 in the well to that received at the coil 21 in air, Figure 10 (not shown), to derive the formation permittivity.

A box made from two blanks 1, 2 as shown in Fig. 1, in which each blank has sides extending from a central portion 3 or 8, and in which one blank 2 forms the body and the other forms the cover 1, the latter being subsequently cut along a line 7, is erected by folding up portions 9 about the portion 8, placing the blank for the cover on the erected body and folding the portions 4 of the cover into contact with the portions 9 of the body in which position they are secured by glue. The corners of the body may be secured by paper strips 12. The glue may be applied to the portion 14 on the body or to the portion 13 on the inside of the lid. As shown in Fig. 4, the box may be erected by placing the erected body 2 upon the inverted cover 1 and pressing the cover through a mould by means of the body portion, a tube 26 beneath the mould holds the erected cover in position until the glue has set. The fold lines of the body and cover may be scored, as at 5, 7 for example. If the cover is cut at 7 along three sides the fourth side forms a hinge. Alternatively, all four sides can be cut and a label secured to the box, the label being cut around three sides to open the box, the fourth side forming the hinge.

Title: Improvements in damping devices for vibratory apparatus
IPC: H04R1/22
Filed: 1923-10-04
Abstract: 205,797. Signal Ges. Oct. 18, 1922, [Convention date]. Drawings to Specification. Damping arrangements for indicating, recording, and integrating apparatus.-For damping vibrating structures, oscillatory mechanical systems act directly on braking chambers, filled with liquid or gaseous media and constitute part of the walls of the same; the said walls being provided with narrow openings and the braking chambers being constructed as resonators and tuned to the frequency of the system to be damped. The invention may be applied to a telephone receiver, but is also applicable to other apparatus in which oscillatory structures are used. The oscillatory mechanical system may itself be in the form of a casing whose interior furms the braking chamber. The degree of damping varies with the degree of coupling between the oscillatory structure and the braking chamber and a formula, is given for determining this. Specification 129,670, [Class 118 (ii), Signals], is referred to.

Abstract: 1,151,536. Diver's communication system. M. COPEL. 3 June, 1966 [4 June, 1965], No. 24903/66. Heading H4R. Speech signals from a diver operating in an ambient atmosphere of helium and/or high pressure are rendered more intelligible by selecting two or more separate frequency bands from the speech signal and moving them down in frequency so that they are closer together, but not overlapping. In the described embodiment, the bands selected are 850 to 1700 c.p.s. and 2400 to 5000 c.p.s. and they are modulated twice, first by a common frequency of 8000 c.p.s. and then the upper sidebands are modulated by frequencies of 8600 and 9000 c.p.s. respectively from which the lower sidebands of 250 to 1100 c.p.s. and 1400 to 4000 c.p.s. are selected, added together and reproduced. It is suggested that a lower frequency band may be transmitted unchanged. Circuits for a system in which speech signals from three divers may be treated by apparatus according to the invention in order to allow them to converse easily with one another or with a tender, are illustrated in Figs. 4a, 4b and 4c (not shown).
