Patent GB-1067394-A (GB)
Title: Location system
IPC: G01S1/30
Filed: 1965-02-23
Abstract: 1,067,394. Radio position finding. CSF COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 23, 1965 [Feb. 25, 1964], No. 7857/65. Heading H4D. The invention is concerned with the determination of the position of an observer station (Po), Fig. 2 (not shown) with respect to three determined positions (MA), (MB) and (MC) in the trajectory of a missile and involves the determination of distances (PA), (PB) and (PC) by phase comparison methods A central station (CS), Fig. 3 (not shown), comprises, Fig 4, three antennµ AE 1 , AE 2  and AE 3  in an L-shaped configuration, which, by mono pulse techniques determine continuously the instantaneous co-ordinates of the missile. These co-ordinates are transmitted to the missile by appropriately phase-modulating in MOP the output of oscillator P. The basic frequency of oscillator P is determined by precision clock HoSo. The signal from the central station is received by the missile, Fig. 5, which doubles the frequency of the signal and transmits it to the observer station, Fig. 6. The transmission is also received back at the control station. By means of a servo frequency control loop-comprising, frequency-doubler X2, feeding twice the transmitted basic frequency to one input of a mixer ME, having the received transmission F 2  fed to its other input to produce a frequency f 1  +f 2 , a frequency comparator, comparing the frequency f 1  +f 2  with that of the output of multiplier M, to produce an error signal which, by way of control means VCO alters the basic frequency of oscillator P-any Doppler shift in the signal retransmitted by the missile is cancelled out and the missile transmission is received at the observer station as if it were coming from a stationary object. The observer extracts the position co-ordinates of the missile in demodulation DMC and feeds them to computter LP. The observer station also comprises a highly stable clock oscillator HST in absolute synchronism with HoSo in the control station. At two arbitrary times t 1  and t 2  the distances P A  and P B  to the missile are respectively determined from a phase comparison in comparator MEL 2  of the received basic frequency and the output of H.S.T. The differential distance (P B  - P A ) is then calculated and stored at M1P. Distance measure. ments are continued until a time t 3  when the distance P C  is found to be such that (P B  - P A ) = (P B  - P C ), at which time the co-ordinates of the missile are determined. Then if the co-ordinates of the missile at times t 1 , t 2  and t 3  are respectively (O, Y A , Z A ), (O, Y B , Z B ), (O, Y C , Z C ), and the co-ordinates of the observer station are (X 0 , Y 0 , O), then Y 0  is given in computer C.A.C. by:- and X 0  by

Title: Improvements relating to air rifles and similar weapons
IPC: F41B11/648
Filed: 1931-03-14
Abstract: 371,548. Pneumatic smallarms. WEBLEY & SCOTT, Ltd. and STATHAM, A. E., 81, Weaman Street, Birmingham. March 14, 1931, No. 7883. [Class 119.] Relates to air rifles, air pistols, and the like, of the kind in which the barrel acts as a cocking lever. According to the invention, the breech end of the barrel co-operates with a rotatable locking member which, upon rotation, is adapted to lock the barrel in the firing position and simultaneously to draw the breech end thereof into airtight engagement with the fixed breechblock. In the form shown, the barrel 7, Fig. 1, of an air rifle is pivoted to the forward end of the air compression chamber 11. The breech end of the barrel is formed with an annular recess 7a, Fig. 2, which is adapted to enter a slot 8a of a rotatable U-shaped member 8, Fig. 6, having a screw-threaded engagement with the breech-block 9. The breech-block is vertically slotted at 9b to receive the rear end of the barrel. The barrel is embraced, in its firing position, by the member 8 when the latter is rotated by a handle 10. At the same time, due to the screw-threaded engagement between the member 8 and the breech-block, the member 8 moves rearwardly and the rear face thereof is brought to bear against the tapered wall 7b of the barrel recess 7a. The rear face of the barrel is thereby brought into airtight abutment against a resilient washer 14 interposed between the barrel and the breech-block. A set-screw 8d limits the angular movement of the member 8.

Water may be added before or during step (iv). HEDP (crystalline or amorphous) may be isolated from the resultant aqueous solution by evaporation, crystallization, precipitation with an organic solvent, flash drying, or drum drying. The various reactions may be effected batchwise or continuously at, above or below atmospheric pressure and in the presence of a silicone anti-foam agent. The acetyl halide and aqueous acetic acid distilled off during steps (i) and (iv) respectively may be combined to produce glacial acetic acid which is recycled to step (i).

Title: Process for the preparation of diethylamide of d-lysergic acid
Filed: 1944-04-28
Abstract: The diethylamide of d-lysergic acid is prepared by subjecting to the action of diethylamine the azides of d- or dl-lysergic acid or of d- or dl-isolysergic acid or mixtures of these azides, followed by a separation of the required d-lysergic acid diethylamide from the reaction product which also contains d-iso-lysergic acid by chromatographic adsorption or by fractional crystallisation.  In examples (1) d-isolysergic acid is treated with sodium nitrite to form the azide which is then reacted with diethylamine in ether solution.  The product consisting of a mixture of the diethylamides of d-lysergic and d-isolysergic acids is separated by chromatographic adsorption.  The iso - compound is treated with an acid or an alkali to convert it to an equilibrium mixture of the diethylamides of d-lysergic and d-isolysergic acids which may be again treated as before.  The d-lysergic acid diethylamide on treatment with d-tartaric acid in methanol yields the neutral tartrate; (2) as in example (1) with slightly varying experimental conditions; (3) rac-isolysergic acid hydrazide is converted into the azide as in example (1) and then reacted with diethylamine to form a mixture of the rac-diethylamides of isolysergic acid and lysergic acids.  This mixture is separated by chromatographic adsorption.  From the rac-diethylamide of lysergic acid the diethylamide of d-lysergic acid can be obtained by means of the neutral tartrate. Specification 480,822 is referred to.

Filed: 1929-03-13
Abstract: 329,741. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). March 13, 1929. Naphthylamine carboxylic acid derivatives are made by treating the alkali-metal salt of a 2 (4<1> hydroxyarylamino)-naphthalene in which the aryl group has the 3'-position free and may carry one alkyl group, with carbon dioxide at a raised temperature and pressure. The starting materials may be obtained .by condensing 2-hydroxy-3- naphthoic acid with an ammophenol or ammocresol in which the hydroxyl is pto the amino group, and splitting off the 3-carboxyl group. The carboxylic acids, including the alkyl derivatives, are used as dyestuff intermediates. In examples, 2-(4<1> hydroxyphenylamino) naphthalene, 2-(4<1> hydroxy-2<1>-methylphenylamino)naphthalene, 2-(4<1> hydroxy-31 methylphenylamino) naphthalene, are treated in caustic alkali solution with carbon dioxide under pressure, to give the corresponding 3'-carboxylic acids.

Title: Improvements in or relating to the manufacture of concentrated sweetened milk products and substances derived therefrom
IPC: A23C9/158
Filed: 1935-03-18
Abstract: In the manufacture of concentrated sweetened milk and of products such as paste, block and powder derived therefrom, fat-soluble vitamins are incorporated in the form of an emulsion in concentrated sweetened milk in the fresh milk before or after it is pasteurized and prior to or during the early stages of the concentration, water-soluble vitamins emulsified in concentrated sweetened milk being added at any stage in the process.  The emulsion of fat-soluble vitamins may be added by emulsifying in the milk.  In an example, fish oil, e.g. cod or halibut liver oil or concentrates or extracts thereof, is emulsified by stirring under nonoxidizing conditions with a small amount of concentrated sweetened milk and the emulsion included in the fresh milk which is then subjected to concentration during which the sugar is added.  Vitamin C in the form of ascorbic acid or lemon or other fruit juices or extracts and an extract containing vitamin B may after emulsification with concentrated sweetened milk be added during the concentration.  The addition of the vitamin C emulsion is made slowly in small quantities to prevent coagulation of the milk.
