Title: Acid addition salts of erythromycin and of carbomycin
IPC: C07H17/08
Filed: 1954-05-28
Abstract: The d-gluconic and d-glucoheptonic acid addition salts of erythromycin and carbomycin are prepared by reacting erythromycin or carbomycin with d-gluconic acid or d-glucoheptonic acid in an inert solvent solution such as water or ethanol.  It is preferred to hydrolyse the lactones of d-gluconic acid or d-glucoheptonic acid to the respective acids by e.g. heating an aqueous solution of the lactone on a steam bath for 2 hours and to use the acids so formed for the preparation of the acid salts.  The salts are isolated by (a) freeze drying the reaction products and washing out the excess antibiotic base, or (b) adding to the reaction products a non-solvent for the salt, e.g. ether.  The acid salts are stable for several weeks in aqueous solution and may be injected intravenously (see Group VI).  Erythromycin d-glucoheptonate melts at 95-140 DEG  C.  It is soluble in water, dioxane, acetone propylene glycol and water-soluble alcohols and is insoluble in ether, chloroform, toluene, benzene and ethylene dichloride.  Erythromycin d-gluconate melts at 110 DEG  to 130 DEG  C. and has similar solubility characteristics to erythromycin d.glucoheptonate.  Specification 708,159 is referred to.ALSO:A therapeutic preparation comprises (a) erythromycin d-gluconate, (b) erythromycin d-glucoheptonate, (c) carbomycin d-gluconate or (d) carbomycin d-glucoheptonate in a parenterally administrable vehicle.  Specified are sterile water, saline solution, aqueous propylene glycol solution and aqueous buffer solutions.  Specification 708,159 [Group IV(b)] is referred to.

Abstract: 955,143. Statistical apparatus. EASTMAN KODAK CO. May 6, 1960 [May 7,1959], No. 16049/60. Heading G4M. In a system for preparing address labels from a mailing list compiled from punched cards, in which the information stored on the cards is transferred to a magnetic tape, e.g. as in the system disclosed in Specification 874,473, and the magnetic tape is then used to control a printer, data identifying a particular magazine to which a punched card relates, and stored in a predetermined column of the card, is used to print an identifying mark 50, Fig. 2 on the address label derived from that card so that the label may be readily associated with that particular magazine. Data read from each card is stored on a 6- channel magnetic tape 10, Fig. 1, and a timing bit is associated with each code character. The pulses from the timing track are used to gate the successive code characters through gates 16 and to step on a ring counter 18. Counter 18 has as many stages as there are character positions in each label, and the output pulses from each stage are used to enter each code character on leads 19 in any predetermined order into the appropriate one of stores 20-1, 20-2 &c. each associated with a different line of a label. After each set of characters has been entered in stores 20-1, 20-2 &c., pulse generator 25 steps on a ring counter 30 to read out corresponding characters of each line of the label simultaneously and successively. Each code character read out is decoded at 40-1, 40-2 &c. and then routed to a matrix 28-1 &c. to energize the appropriate inputs of a stylus printer 29 associated with that line. The output of ring counter 18 which corresponds to the predetermined column. identifying the magazine with which the label is to be associated is connected to open gates 37-1 to 37-4. For a four line label as shown, decoder 35 may have up to 16 outputs which are connected through a plugboard 36 to the inputs of gates 37-1 to 37-4. When the predetermined column of code is read, one or more of bi-stable circuits 39-1 to 39-4 are set, and at the appropriate time in the read-out cycle (determined by counter 30 and plugboard 51) pulses are routed to one or more of matrices 28-1 &c. to record a mark 50 in one or more lines of the label. Marks 50 may correspond to the final digit of the number printed at the bottom right of each label. Specifications 711,497, 711,498, 792,861, 797,548 and 891,953 also are referred to.

Title: Improvements in or relating to systems for indicating the passage of vehicles over roadways
IPC: B61L1/16
Filed: 1951-07-09
Abstract: 704,476. Locating vehicles. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 9, 1951 [Sept. 16, 1950], No. 16254/51. Class 37  Apparatus for detecting passage of vehicles comprises two similar detector coils D1, D2, each having two windings D11, D12 and D21, D22, placed in a roadway and connected so that D11, D12 are series energised 'from an A.C. source Un and the secondary voltages induced in D12, D22 are in series opposition and normally cancel out. The additional coupling between the detector coils due to the passage of a metallic vehicle develops an unbalance voltage Ut on the primary of the input transformer T2 of the known double triode phase sensitive amplifier F, energised from the A.C. source through transformer T3 to develop a unidirectional output voltage Ur across the series load resistances M1 to M4, whose sense depends on the phase of the input unbalance voltage, which energises a polarised relay R to close contacts 1, 2 or 1, 3 respectively on the passage of a vehicle, according to the phase of the unbalance voltage and the sense of voltage Ur. A unidirectional control voltage Uf is tapped off the load resistances between the junction of M1, M2 and a slider on resistance M4, and is connected to the input of a compensating circuit K comprising a resistance-capacitance time delay network M11 to M14, C13, C14 connected to the grid circuits of a push-pull double triode phase modulator which is A.C. energised from a transformer T4 supplied from the A.C. source, whose dual secondary windings are each connected at one end to the associated triode anode, and at the other end to the common cathode and grid return point through the primary of transformer T5 which is tuned to the A.C. frequency. The transformer secondary 'injects a feedback voltage Uk in series with the unbalance voltage on the primary of transformer T2 after a time delay due to the R.C. network in. such phase as to counteract the unbalance voltage, so that if a passing vehicle remains in the vicinity of the coils for a time greater than the operation time of the delay network, the input signal due to that vehicle is cancelled out, and the apparatus is able to continuously respond to other passing vehicles.

[Class 80 (ii).] Change-speed. gearing comprises in combination a driving flywheel 8, Fig. 1, a main clutch 9 and at least one two-speed epicyclic eccentric train. The arrangement shown comprises two such trains A, B and a reversing train C operated by cams 55, 56, 57 on a control shaft 54 which carries a fourth cam 60 for operating the main clutch 9. The train A comprises an internally and externally toothed ring 15, Fig. 2, meshing with a pinion 11 fast on the clutch shaft 6 and with ari internally toothed drum 16 connected by a disc to a driving pinion 18 of train B. The ring 15 turns loose on an eccentric 14 loose about the shaft 6 and rigid with a disc with peripheral clutch teeth 13. The train A is operative to reduce speed when the teeth 13 are engaged by a dog 47 on a control lever 43 of the train. The train A turns solid when a clutch ring 36 splined on the drum 16 is engaged with the teeth 13. The train B is similar; its driven drum 25 being rigid with a driving pinion 27 of train C. Train C comprises planets 28 which mesh with the pinion 27 and with teeth on a drum 33 rigid with a driven coupling flange 35.

Title: Process for the manufacture of ethylene
IPC: C07C11/04
Filed: 1954-06-08
Abstract: Ethylene is prepared in a yield of 60 per cent or more by the thermal cracking of liquid hydrocarbons in which the ethylene is removed, and fresh quantities of liquid hydrocarbon added to the mixture in the reaction zone and the whole recirculated through the reaction zone after removing the ethylene therefrom.  The initial hydrocarbons may be diesel oil, kogasin, the hydrocarbon oil derived from the catalytic hydrogenation of CO or slack wax and the process may be carried out in hollow tubes or in large-capacity reactors with or without solid or moving contact masses such as oxides of the second, third, fourth and sixth groups of the periodic system especially aluminium oxide, magnesium-aluminium silicate, magnesium-aluminium molybdate, and potassium-magnesium silicate.  In a typical example, a diesel oil of density 0.84 was injected at the rate of 10 kgs. per hour together with 16.5 kgs. of recycle oil into a tube maintained at 750-800 DEG  C. by external heating.  After running for one hour the ethylene and hydrogen were selectively separated by adsorption on active carbon and the remainder recycled.  At the end of 24 hours 67 per cent ethylene had been produced.
