Title: Process for the production of amides
Filed: 1930-03-05
Abstract: Amides are obtained by causing aliphatic monohydric alcohols to react with formamide in the presence of an atmosphere constituted partly by ammonia gas.  The Specification as open to inspection under Sect. 91 (3) (a) states that the reaction may be facilitated by the use of ultra-violet or infra-red rays.  It also includes the use instead of formamide of its synthesis constituents, carbon monoxide and ammonia, or of ammonium formate or its synthesis constituents, carbon monoxide, ammonia, and water; and also states that catalysts may be employed.  This subject-matter does not appear in the Specification as accepted.ALSO:Amides are obtained by causing aliphatic monohydric alcohols to react with formamide in the presence of an atmosphere constituted partly by ammonia under pressure.  According to an example acetamide is obtained by introducing equal parts of formamide and methanol into an autoclave with ammonia gas at an initial pressure of 7 kg. per sq. cm.  The mixture is heated to 150-300 DEG C. and the pressure raised to 100 kg. per cm.2 by forcing in a neutral gas such as nitrogen.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use instead of formamide of its synthesis constituents, carbon monoxide and ammonia, or of ammonium formate or its synthesis constituents, carbon monoxide, ammonia, and water; also the use instead of methanol of carbon monoxide and hydrogen.  Further, it is stated that the reaction may be assisted by the presence of catalysts or by irradiation with ultra-violet or infra-red rays.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1493622 Data transmission; multiplex exchanges GENERAL ELECTRIC CO Ltd 18 Feb 1975 [18 Feb 1974] 7301/74 Heading H4P A data multiplex exchange has a plurality of grouped input subscribers, individual groups 10 being unirate, multiplexed at 1 over paths 11 to respective circuits 2 which arrange/rearrange time slot occupancy and performing further multiplexing of streams on to highway 5, with a selector 3 providing at 19À2 b/s a signal path and sub address memory controlling timing selection of the various channels, the number of streams being dependent on input bit rate at 10 and include idle channels. Non idle channels have all zeros inserted when not in use at any time. Highways 5 are applied to a cross point space switch controlled by a cyclic store of cross point addresses, one for each channel, which are written in under control of 8 and processor 9, there being 32 inputs with 32 outputs to highway 7. For a particular input highway 5, each channel is transmitted through a particular one of the 32 cross points for the duration of transmission; each cross point may be used several times within a 320 channel frame so that several channels may have the same path through the space switch. An output highway 7 therefore carries at 1À92 MHz a selection of channels from different input highways 5. An output circuit 12 corresponding to 2, one for each highway 7, comprises an output store 14, sub address memory 14 effecting the first stage of demultiplexing to produce streams of 60 Kb/s and may switch time slots on 7 to any selected slot on 19 before application to final demultiplexer 15. The various streams are then distributed amongst 320 subscribers. The arrangements are described in greater detail in relation to Figs. 2 and 3 (not shown).

Title: Method of separating betaine hydrochloride and potassium chloride from waste molasses
IPC: C01D3/06
Filed: 1928-03-13
Abstract: 304,071. Takayama, Y. March 13, 1928. Betaine hydrochloride is separated from waste molasses by treatment with hydrochloric acid or by passing hydrochloric acid gas. Potassium chloride first separating out is filtered off, and the filtrate is then concentrated with crystals of betaine hydrochloride with further potassium chloride are obtained. These are filtered, dissolved in water, and the aqueous solution neutralized with lime or calcium carbonate to give free betaine; it is then concentrated further and the potassium chloride crystallized out. The betaine hydrochloride may be regenerated by the addition of hydrochloric acid to the filtrate, or by the addition of sufficient sulphuric acid to precipitate the calcium as sulphate at the same time converting betaine into betaine hydrochloride. The betaine hydrochloride thus obtained may be further purified, if necessary, by recrystallization.

Abstract: 1,131,681. Drying apparatus. ADDRESSOGRAPH MULTIGRAPH CORP. 22 Feb., 1966 [8 July, 1965], No. 7782/66. Heading F4G. [Also in Division G2] A drying apparatus, intended for drying duplicating masters after they have been processed, so that they can then be stored for future use conveys the masters through a housing where they are exposed to radiant heat, and then passes them into a storage container. The master sheets, on leaving the processing unit (not shown) enter the drier between guides 28, 30, which have ribbed inner surfaces to prevent the wet sheets from sticking thereto. A further guide 32 (in the full-line position) leads the sheets to a first pair of soft rubber rollers 36, 38, after which they pass on between further guide members 40, 42. These are spaced widely apart (in a lateral direction), so as to intercept only a minimum of the heat radiation from the infra-red heating elements 50, 52, disposed one above and one below the sheet. Each heater lies within a semicircular reflector, 54, 56, made preferably of etched aluminium. A temperature control unit (80, Fig. 3a, not shown) maintains a constant optimum temperature, e.g. 160 F. After drying, the sheets pass through a further pair of rollers 44, 46 to a collecting bin 100, which is provided with a fan (120, Fig. 3b, not shown) for drawing out and expelling moist air from the apparatus. Stop rods (112, 114, Fig. 3b, not shown) may be provided in the bin for retaining sheets of different sizes. If, instead of drying and storing the sheets for future use, it is desired to use a sheet immediately after processing, a push-rod 154 is provided by means of which the guide 32 can be tilted from its normal (full-line) position to the position shown in broken lines. A sheet entering between guides 28, 30 is now diverted upwards along another guide 34 and out of the apparatus on to a receiving shelf 158.

Title: Method for estimating the ambiguity function and device for carrying out said method

Filed: 1973-02-16
Abstract: 1380888 Evaluating the ambiguity function COMMISSARIAT A L'ENERGIE ATOMIQUE 16 Feb 1973 [24 Feb 1972] 7816/73 Heading G1U [Also in Division G4] A method of approximating to the ambiguity function A(r,f) of two functions X(t) and Y(t), which is defined generally as:- for the special case when X(t) and Y(t) are both time varying electric signals, comprises a first phase in which approximations to the N values of the product X(t) Y(t-r) for a set of N values of r, and a particular value of t, are evaluated, and a second phase in which the Fourier transform of each of the N values is evaluated by allowing t to vary over an interval -T to +T. The first phase is implemented by adding 20, 32, Fig.3, a random signal B 2 , B 1  from generators 18, 34, to the two signals Y and X respectively to produce signals Z 2  and Z 1  (the drawing actually shows the case when Y=X) where the signals B 2  and B 1  are independent and uniformly distributed over the interval -T to +T, by producing 22, 36 two-level signals sgn Z 2  and sgn Z 1  respectively indicative of the signs of the sum signals Z 2  and Z 1 , and by gating 24, 38 the signals sgn Z 2  and sgn Z 1  to N Ex Or gates 42, the samples of sgn Z 2  passing via a shift register 28. Thus the expectation of the output of any particular Ex Or gate 42 is proportional to the product X(t) X(t-r) for a value of r that depends upon the gate. During the second phase of the calculation, the sequence of outputs from each gate 42 is applied to a corresponding Fourier transform calculating unit 50, in which the values in each sequence are each multiplied by a set of functions cos 2#f i t and sin 2#f i t, for a suitable set of values of fi, and for each value of f; the resulting products are integrated over time, these integrals, for each value of fi, representing the real and imaginary components of the Fourier transform of X(t) Y(t-r) for a particular value of r, and appearing on terminals 52, 56 respectively. (Each terminal 52, 56 thus represents a set of f i  terminals.) The modulus of the Fourier transform is also produced on a central terminal 54. Thus, finally, sections of the surface Z=A(r,f) parallel to the plane r=o are obtained by taking the outputs from a particular one of the Fourier transform units 50, and sections parallel to the plane f=o are obtained by taking one output from each unit 50, in accordance with the value of the frequency. Each Fourier transform unit 50, comprises a set of multipliers 68, ..., 84, Fig.4, which receive the output from the associated Ex Or gate 42, and the signals cos 2#f i t from a common reference generator 48, and a set of multipliers 72, ..., 88 for the sine products. Each gate feeds an integrator, such as integrator 70 to provide either the real or imaginary component for a particular frequency f i , and each pair of integrators such as 70 and 74, feeds a unit 80 which produces the modulus of that particular frequency component.
