Title: Sulphonyl-urea derivatives
Filed: 1957-11-28
Abstract: The invention comprises compounds of the formula <FORM:0816319/IV (b)/1> in which R is an alkyl group and R1 is the residue of a lower unsaturated aliphatic monocarboxylic acid containing 1-10 carbon atoms, for example an acrylic, methacrylic, vinylacetic or crotonic acid residue.  The group R is suitably a methyl, ethyl, n-propyl, isopropyl, n-butyl or isobutyl group.  The compounds are made by acylating the corresponding N11-alkyl-N1-sulphanilyl area with a halide or ester of a lower unsaturated aliphatic carboxylic acid such as the chloride, bromide or lower alkyl ester of acrylic, methacrylic, vinylacetic or crotonic acid, preferably in the presence of a condensing agent which is preferably an acid-binding agent such as sodium or potassium carbonate or bicarbonate.  The reaction is suitably carried out in a solvent and at room temperature.  In an example, N1-sulphanilyl-N11-n-butyl urea is treated with crotonyl chloride in acetone in the presence of sodium bicarbonate to give N1-p-crotonylamino - benzenesulphonyl - N11 - n - butyl - urea.

Abstract: 1,035,715. Multiplex systems; multiplex radio signalling. H. HARMUTH. Sept. 17, 1964 [Sept. 17, 1963], No. 38036/64. Headings H4L and H4R. Multiplex system which is one of a class of orthogonal multiplex systems of which frequency and time division are two extreme cases, uses a number of carriers each one of which comprises a sequence of rectangular pulses, and the carrier of ordinal number 2n is produced from the carrier of ordinal number n and the carrier of ordinal number 2(n + 1 ) + 1 is produced from the carrier of ordinal number (n + 1) by doubling the sequence of rectangular pulses in the cycle, while the carrier of ordinal number 2n + 1 is produced from the carrier of ordinal number n and the carrier of ordinal number 2(n+ 1) is produced from the carrier of ordinal number n + 1 by doubling the sequence of pulses in the cycle and inverting the amplitude during the second half of the cycle, n being 0 or even and the carrier of ordinal number 0 being a D.C. of constant value throughout the period. In addition, carriers of ordinal number n may be formed by superimposition of carriers of ordinal numbers a and b where n = a + b and n, a, and b, are expressed as binary numbers and added according to the normal rules of binary addition save that the carry is ignored, i.e. 01 + 01 = 00. Fig. 4 shows a circuit for use either as a modulator, with the signal applied to terminal F and the carrier to terminal A, or for superimposing carriers, with the carriers applied respectively to terminals A and F. The operation of the circuit is such that with one polarity of signal applied to terminal A the output from feedback amplifier V is identical with the input applied to terminal F, and with the other polarity of signal applied to terminal A the output is an inverted version of the input to terminal F. An arrangement for transmitting the signals of 9 teleprinters is described with reference to Fig. 5 (not shown) in which the 9 signals are modulated by 3 carriers to form 3 sub-groups which are in turn modulated by 3 further carriers to form a single group for transmission after a further stage of modulation. A decoder is also described, Fig. 6 (not shown), the arrangement being a mirror image of the transmitter. A synchronizing system has to be transmitted with the carrier signals.

Title: Valves for pneumatic logic apparatus
IPC: F15C3/02
Filed: 1962-10-09
Abstract: 982,016. Valves. BECKMAN INSTRUMENTS Inc. Oct. 9, 1962 [Nov. 9, 1961], No. 38107/62. Heading F2V. [Also in Division G4] Logical operations are performed pneumatically by an assembly of valves of which a single example is shown in Fig. 1 and comprises a slidable valve member 16 having a restricted passage 24 communicating with an outlet 15, a central 0-ring seal 26, and O-rings &c. 20, 21 at each reduced end of the valve member or in end faces 22, 23 of the chamber in which the valve member slides. Alternatively, needle valves may be used in place of the 0-rings. A first pneumatic signal appears at the outlet 15 if it is applied simultaneously to the two inlets 13, 14 whereas a second signal appears at the outlet if it is applied to either or both of the inlets. For example, the second signal may be pressurization and the first signal lack of pressurization or venting. In this case, if 13 is vented and 14 pressurized the valve member will be urged upwardly to cut off 13 and to connect 15 directly with 14, whilst if 13 is pressurized and 14 vented the valve member will move downwardly to isolate 14 and connect 15 with 13 through the restricted passage 24. If 13 and 14 are both vented or both pressurized, 15 will be vented or pressurized, respectively whatever the position of the valve member. According to the invention a unitary structure houses a number of such valves of which each has one individual inlet and one inlet that is common to all of the valves. A " cross-bar " switch may be composed of a matrix of rows and columns of these valves in which each row has a common inlet 13, each column has a common inlet 14 and each valve has its own outlet 15 so that a single outlet may be selected by the application of a signal to one row and one column by manually operated selector valves. Fig. 2 shows a modified valve which operates in the reverse sense, i.e. it will pressurize the outlet 35 in response to pressurization of both inlets 33, 34 but will vent the outlet in response to venting of one or both of the inlets. This valve has a valve member 36 with a reduced intermediate portion provided with an O-ring seal 38 and an unrestricted bore 48. 0-rings 41, 46 coact with the end faces of the valve chamber and restricted passages are formed around the periphery of the enlarged head portions 39, 44 or by small bores (not shown) in the head portions spaced radially outwardly of the O- rings. The modification shown in Fig. 3 operates in the same sense as that of Fig. 2 but has the valving surfaces constituted by inwardly facing parts of the head portions of the valve member. The bore 57 which communicates with the outlet 52 and with the space between the head portions may be extended upwardly to a neck portion (not shown) slidable in a blind bore and corresponding with the neck portion 56 which slides in the outlet 52. " Crossbar " switches may also be formed by assemblies of valves as in Figs. 2, 3.
