Patent GB-831973-A (GB)
Title: Peptides and derivatives thereof, and process for their manufacture
Filed: 1956-07-05
Abstract: The invention comprises amino-acid derivatives and peptide derivatives containing bound to the terminal amino group an acyl residue of the formula <FORM:0831973/IV (b)/1> where Ar is the residue of a mono- or di-nuclear aromatic compound in which the two substituents are in ortho-position, X is oxygen or sulphur and R is the divalent residue of an a -aminocarboxylic acid of the formula H2N-R-COOH, and a process for making them and their esters with alpha-aminocarboxylic acids, by treating an amino acid derivative or peptide derivative containing bound to the terminal amino group an acyl residue of the formula <FORM:0831973/IV (b)/2> where Ar, X and R are as above, or a salt or a carbobenzoxy derivative of such a compound or a corresponding urea of the formula <FORM:0831973/IV (b)/3> with a basic agent and, if desired, esterifying the o-hydroxy- or o-mercaptogroup of the resulting compound with an alpha-aminocarboxylic acid.  By successive esterification of the o-hydroxy- or o-mercapto-group with an alphaamino carboxylic acid and treatment of the resulting compound with a basic agent a peptide chain can be built up stepwise.  The o-hydroxy- or o-mercapto-aromatic acyl group can be split off by treatment with sodium in liquid ammonia to give the corresponding free peptides. The amino acid or peptide derivative containing the group of formula V above may be made by hydrogenating an azido compound having an acyl residue of the formula <FORM:0831973/IV (b)/4> by decarbobenzoxylation of the carbobenzoxy compounds having an acyl residue of the formula <FORM:0831973/IV (b)/5> by hydrogenolysis or by treatment with phosphonium iodide, or by treatment of the corresponding urea with alkali.  The urea may be made by treatment of the carbobenzoxy compound VIII with alkali. The carbobenzoxy compound may be converted directly to the amino acid or peptide derivative containing the acyl residue of the formula <FORM:0831973/IV (b)/6> by hydrogenolysis in the presence of a basic agent.  The carbobenzoxy derivatives are made by condensing the appropriate o-hydroxy- or o-mercapto-aromatic acyl amino acid or peptide derivative with the appropriate carbobenzoxy amino acid chloride. Examples are given. Salicoyl-L-alanine is made by treating salicyclic acid hydrazide and L-phenyl-alanine with sodium nitrite and nitric acid.  The disulphide of thiosalicoyl-glycine anilide is made by reacting the disulphide dichloride of thio-salicylic acid with glycine anilide, and is reduced with zinc and hydrochloric acid to give thio-salicylglycine anilide.

IPC: D04B9/26
Filed: 1918-12-17
Abstract: 136,283. Wildt & Co., and Widdowson, A. Dec. 17, 1918. Circular machines.-Means are provided in a rib machine for producing tucked and striping effects in combination, comprising a vertically movable tucking-cam 1 co-operating with long latch needles, and yarn-changing means the movements of which take place obliquely to the needle cylinder. The cam 1 is attached to a plunger 3 movable upwards against a spring 5 by a patterncontrolled plunger 16 which has a lug 14 extending across the path of a projecting lip 9 of the plunger 3. The lip 9 thus rides up an inclined face 15 of the lug 14, and the cam 1 is locked in its raised position by a pivoted spring catch 10 which moves outwards and engages the underside of the lip 9 by means of the upwardly projecting tooth 22. When tuck fabric is required, the lug 14 is allowed to drop into the path of the catch 10, and moves it back until the projection 22 registers with a recess 23, whereupon the tuck cam drops to the normal low position, at which only the short latch needles clear. The striping threadlayers 24, 25, Fig. 6, are. pivoted to move obliquely on a pin 25<a>, and each has two rear arms 26, 27 and 28, 29 respectively. One arm of each pair makes contact with a cam 30 for moving the finger to the feeding position, and the other with another cam 31 for withdrawing the yarn. The cams 30, 31 are arranged in different planes and are carried on vertically movable pattern-controlled plungers 32, 33. Two sets of dogs are used on the pattern chain to give the cams 30, 31 a high and low position. When the cams are in the high position, the arm 28 will engage the cam 30 to move the thread layer 25 into the feeding position, while the arm 27 will engage the cam 31 to withdraw the thread layer 24 from the feeding position. When the cams are in the low position, the arms 26, 29 are engaged, and the action of the thread layers is reversed.

Patent GB-222110-A (GB)
Title: Improvements in process for the manufacture of magnesium salts
IPC: C01F5/00
Filed: 1924-09-08
Abstract: Pure magnesium salts are obtained by treating magnesium carbonate, dolomite, or calcined dolomite placed in suspension in water or other suitable liquid by carbon dioxide gas in the presence of calcium sulphate or any other salt or solution capable of forming calcium sulphate.  The solution so obtained is first filtered to separate the precipitated calcium carbonate, then boiled to convert the magnesium bicarbonate into magnesium carbonate, and is again filtered.  On evaporation of the filtrate pure magnesium sulphate crystallizes out. To prepare magnesium carbonate, sodium carbonate is added to the solution first obtained by treating with carbon dioxide.  The magnesium carbonate so precipitated is of extreme lightness owing to the presence of magnesium bicarbonate in solution; magnesium oxide is prepared by calcining this magnesium carbonate.

Title: Monitoring of radiation attenuation
IPC: G01N21/53
Filed: 1970-05-02
Abstract: 1352500 Monitoring visibility photoelectrically PLESSEY CO Ltd 29 April 1971 [2 May 1970 13 June 1970] 21188/70 and 28731/70 Heading G1A In an apparatus for measuring visibility in which a radiation source 300, e.g. a tungsten halogen lamp or GaAs lamp, irradiates an atmosphere, and scattered radiation is monitored by a main receiver 306, a further receiver 305 monitors undeviated radiation and the output of this reference receiver is used to control the output intensity of the source. The incident radiation beam is preferably pulsed, using a mechanical chopper or a pulsed source, to prevent interference by ambient light, and the receivers may be Se barrier photocells or Si photodiodes. The light source (308), Fig. 4, (not shown), is pulsed. A multi-vibrator (318) drives a monostable circuit (328) whose output periodically switches ON a pair of transistors (312-314), via a modulator circuit (340) which controls the state of the transistor pair. The light-emitting diode (308) is energized through the transistors (312-314) by a regulating circuit (310). This circuit receives at (302) a control signal from the reference receiver (305), which is compared with a stabilized voltage (362) in a differential amplifier (364). This amplifier controls the current through a transistor (316), which in turn controls the current fed to the diode (308). Hence as the radiation intensity at the reference detector changes, the light source intensity is altered to compensate for this, and the averaged output from the main receiver gives a direct indication of visibility. A phase-sensitive detector may be employed as the final element in the output circuitry, its control input being derived from the main receiver output. A number of apparatuses may be combined to derive spatial information.

Abstract: 276,974. Sousedik, J. Sept. 6, 1926, [Convention date]. Alternating-current motors. - An automatic starting device for induction motors comprises a rotary magnetic body formed as a casing with two sides and a connecting member, centrifugally-operated magnetic cores between the sides, short-circuited coils, and coils connected to the rotor, the parts being so arranged that at the beginning of the starting operation the cores cause the flux of the coils to close through the sides of the casing practically without passing through the short-circuited coils, and later, as the speed increases, to close also through the cores and connecting member and so thread the short-circuited coils. In the form illustrated, suitable for mounting on the shaft 10 of a motor, the upper and lower parts of the Figures show respectively the condition when the motor is stationary and running. A two-part magnetic casing 11, 12 encloses auxiliary coils 13, 14 connected in series with the two branches of the rotor winding and linked magnetically with a short-circuited coil 15. Segmental magnetic members 16, which may be guided by feathers 17, are pressed inwards by springs 18 giving an inductive value to the coils 13, 14 with a flux distribution as shown in dotted lines at 19. When the motor has reached a certain speed the members 16 move outwards centrifugally, giving the flux distribution shown at 21, i.e. giving a practically non-inductive value to the coils connected to the rotor. The device, may be filled at 22 with oil.

In the embodiment shown the chuck 2 has radially movable jaws 5 comprising master jaws 5a having teeth 5c meshing with teeth 6b on tangentially movable slide blocks 6. The latter are moved by rack-and-pinion mechanism 6a, 7, the pinion 7 being secured for rotation with a torque tube 8 extending through spindle 1. The tube 8 is connected at the rear end of the spindle with a torque actuator 3 comprising cylinder 11 housing a rotary vane assembly 12 to which tube 8 is secured. An extension spindle 13 of the assembly 12 is encompassed by a fixed housing 14 through which fluid-either pneumatic or hydraulic-to operate the actuator 3 passes. The jaws 5 are associated with the slide blocks 6 in such a way that they disengage from each other at a preset radial position, thus allowing jaw replacement &c. In order to prevent drive from being transmitted to the spindle 1 while the jaws are free of the slide blocks 6, a control mechanism responsive to the angular position of the vane assembly 12, and hence slide blocks 6, is provided. The mechanism incorporates an axially movable pin (17), (Fig. 4, not shown), in the extension spindle 13, which moves when operating pins (19) are moved radially by their co-operation with cam-tracks formed at appropriate angular locations on a flange ring 15. Pin (17) pushes a switch-operating member 21. In another embodiment (Figs. 7 and 8, not shown), an axially movable pin (17a) is apertured to receive an operating pin (19) which bears on axially-profiled cam tracks on a flange ring (15a). In a further embodiment (Fig. 9, not shown), the extension spindle (13a) is hollow and mounts a disc (17c) which moves axially to operate switch member (22a) when pins (17b) ride on cam-tracks formed on a ring (15b). In other embodiments (not shown) the control switch can be inductively, capacitively, optically, or magnetically operated.
