Title: Process for preparing 3,5:4,6-protected derivatives of l- or d- gulonic acid, their use in preparing 2-keto-l- or d- gulonic acid or their esters of l- or d- ascorbic acid and certain novel 2-nitratogulonate intermediates
IPC: C07D493/04
Filed: 1978-06-09
Abstract: The invention relates to a process in which a 3,5:4,6-protected derivative of L- or D-glulonic acid is prepared by contecting L- or D-gulono-1,4-lactone with an aldehyde dialkyl acetal, or with an aldehyde and an alcohol, in the presence of an acid having a pKa of less than 3. This protected derivative may be oxidised and hydrolysed to 2-keto-L- or D-gulonic acid or ester thereof, which in turn may be hydrolysed to L- or D-ascorbic acid. L-ascorbic acid is of course Vitamin C. The invention also relates to the novel intermediates produced by the above processes.

Similarly the tray 30 can only be extended when in the lowered position. An independently energizable timer circuit is included which on energization opens switches in the holding circuits so that the trays are raised in the correct sequence. The carcass ply trays 20, 22, 24, 26, 28 are supplied from rolls of carcass ply stock mounted on shafts 60, 62, 64, 66, 68 each rotatable by means of a reversible electric motor 116, the ply passing to a festoon and from there through a centring device to a tray.

Title: Fluidised beds
IPC: B01J8/46
Filed: 1978-09-14
Abstract: An article, for example a glass sheet, is treated in a gas-fluidized particulate material by advancing the article along a path leading into the gas-fluidized particulate material and extracting gas from a region of the path at a rate sufficient to pack the particulate material in that region and thereby obturate the path.

Title: Ignition coil and capacitor analyzer

Filed: 1975-12-19
Abstract: 1531468 Testing IC engine ignition circuits UNITED TECHNOLOGIES CORP 18 Dec 1975 [19 Dec 1974(2)] 51956/75 Heading G1U An ignition circuit testing system exploits the fact that if the ignition circuit is in good condition then with the secondary winding open circuited for each cylinder firing pulse the voltage, (a), Fig. 3, across the contact breaker should rise above a certain minimum (about 250V) and should execute a certain number of oscillations. To this end, a potential divider 64, ..., 68, Fig. 1, is connected to the contact breaker so that the voltage across it can be compared with a pre-set threshold 74, and its oscillations can be squared 34 (see also (b), Fig.3) and counted. In the preferred embodiment the contact breaker voltage is examined successively over sixteen firing cycles in relation to a particular cylinder, the plug lead 28 for this cylinder being removed and being connected to a signal conditioning circuit 30 to provide appropriate gating signals. The number of firing cycles in which the contact breaker voltage exceeds the pre-set threshold 74 are counted 58, and the total number of oscillations of the voltage are counted 56, 57, so that the most significant four bits 57 represent the average number of oscillations per firing cycle. The resulting counts are then applied to a logic circuit which produces an indication of the likely condition of the ignition circuit. For example, if the number of firing cycles during which the contact breaker voltage exceeds the threshold lies in the 25% to 75% range, lead 90, and if also the average number of oscillations lies in the 4 to 10 range, lead 108, then an indication "intermittent arcing", lead 118, is produced.

Filed: 1990-10-01
Abstract: Process for solubilising peptide in a water-immiscible organic solvent, consisting in bonding a lipophilic group to the terminal carboxylic group of the said peptide via an amide or ester bond; this lipophilic group is characterised in that when it is bonded to L-serine a molecule is obtained whose solubility in water at 25 DEG C is lower than 30 g/litre. This lipophilic group is chemically defined and nonpolymeric. The invention also relates to a process for the synthesis of optionally protected peptides, in liquid medium, characterised in that it starts with an amino acid or a peptide solubilised in organic medium by a lipophilic A-L group bonded to the carboxylic functional group of the starting amino acid or peptide and in that the amino acids or the peptides to be condensed, which are activated on their acidic functional group and protected on their amine functional group and optionally on their side chain, are added. The peptides originating from the synthesis are optionally employed for the synthesis of medications, vaccines and agri-foodstuffs or plant protection products.

Granted: 2021-03-22
Abstract: The present invention provides a temporal Wheeler's delayed-choice demonstration apparatus and demonstration method to demonstrate Wheeler's ideas in a hybrid system consisting of massive particles and massless photons. The cold atomic Raman quantum memory makes the heralded single-photon divided into a superposition of atomic collective excitation and leaked pulse, thus acting as a memory-based beam splitter. In addition, the adjustable proportion of the beam splitters can be realized by changing the relative proportion of the quantum random number generator, the storage efficiency of the second memory-based beam splitter, and the relative storage time of two memory-based beam splitters, so as to observe the wave-particle complementarity of light. Moreover, the temporal Mach-Zender interferometer enables two paths combined in a single-mode fiber, thus greatly simplifying the experimental configuration. Therefore, the present invention provides a temporal Wheeler's delayed-choice demonstration apparatus and demonstration method, which has a novel structure, is easy to construct and has strong anti-interference.
