Title: Improvements relating to electric pulse signalling systems
IPC: H04B1/46
Filed: 1945-07-18
Abstract: 596,092. Multiplex pulse signalling. SIEMENS BROS. & CO., Ltd., REED, M., and MOSS, S. H. July 18, 1945, No. 18418. [Class 40 (v)] [Also in Group XXXV] In a two-way multiplex pulse modulation system in which intercalated transmitting and receiving gating periods are provided at each station, synchronizing signals are transmitted from the controlling station which automatically adjust the gating periods at the controlled station so that incoming pulses thereat fall correctly within the appropriate gating periods and provision is made for adjusting, manually or automatically, the relative timing of pulses incoming to the controlling station and the gating periods thereat, so that these pulses fall correctly in the appropriate gating periods. As described, the said adjustment is automatic and comprises a control of the recurrence frequency of the gating period master pulse generator. The system will operate correctly when the pulses c, Fig. 3, of one received channel train are arranged to occur at the midpoint of a receiving gating period pulse b at the controlling station, the outgoing pulses a of a synchronizing pulse train occurring at the leading edges of the gating pulses. A circuit for producing this result is shown in Fig. 2. The master gate pulse generator, the frequency of which is automatically controlled, comprises a transitron oscillator VC, producing rectangular pulses at its screen grid, which are amplified and clipped by valve VD. The outgoing narrow synchronizing pulses, at terminal TA, are derived from the anode of VD by the differentiating circuit QC, RE, the negative trailing edge pulses being clipped by diode VE. The phases of the rectangular gatepulses and an incoming pulse train at terminal TC are compared by applying them respectively to the control grids of valves VB, VA, the anodes and suppressor grids of which are interconnected to form a flip-flop multivibrator circuit. Between gate pulses, VB is passing no anode current or screen current. On the occurrence of a gate pulse, screen current flows, curve d, Fig. 3, and is suddenly reduced in value when a narrow pulse arrives at terminal TC, cutting off VA and driving the suppressor grid of VB positive. When the gate pulse ceases, the circuit reverts to the original state, VA being conducting and VB being cut off. The relative timing of the pulses determines the mean screen voltage of VB, curve e, Fig. 3, and this controls the frequency of the master gate pulse generator VC, being applied through smoothing circuit RB, QS to its control grid. The circuit is so adjusted that the frequency correction is always in such a sense that the pulse at terminal TC is caused to occur at the mid-point of the gating pulse.

Title: Physically anti-inflammatory steroids for use in aerosols
IPC: A61K/
Filed: 1972-04-20
Abstract: 1429184 Anti-inflammatory steroid crystallisates ALLEN & HANBURYS Ltd 18 April 1973 [20 April 1972] 18421/72 Heading C2U [Also in Division C4] The invention comprises an anti-inflammatory steroid in the form of a crystalline solvate with a halobydrocarbon or such a crystalline material from which part or all of the halohydrocarbon has been removed, the particle size of substantially all of the steroid material being such as to permit inhalation into the human bronchial system when dispersed as an aerosol, e.g. 2- 20 Á. Several specific steroids of the pregna-1,4- diene-3,20-dione series are mentioned. Specified halohydrocarbons are CH 2 Cl 2 , CHCl 3 , CFCl 3 , CCl 2 F 2 , C 2 Cl 2 F 4 , C 2 Cl 3 F 3  and C 2 ClF 5 . Preparation.-The initial unsolvated steroid is first contacted with the halohydrocarbon. Simple suspension with concurrent comminution yields an inventive product. Alternatively the halohydrocarbon is mixed with a solution of the steroid in a conventional steroid solvent (e.g. MeOH, EtOH, Pr<SP>i</SP>OH, HCHO, CH 2 Cl 2 , acetone) and the resulting mixture is either crystallized at low temperature, e.g. -29 to -40 C., or distilled until the conventional solvent has been removed whereupon the solvate crystallizes. The optional removal of the halohydrocarbon from the solvate may be effected by heating at up to 60 C. in a vacuum, and may also take place automatically upon comminution. The latter may be effected ultrasonically or in a ball or fluid energy mill. Anti-inflammatory aerosol compositions comprise a suspension of a product of the invention in an aerosol propellant and a dispersing agent. (The steroid has a modified crystal structure and does not exhibit crystal growth in the propellant.)

Abstract: 616,184. Making steam generators. PHILIPS LAMPS, Ltd. June 19, 1946, No. 18441. Convention date, June 21, 1945. [Class 83 (ii)] [Also in Group XIII] A heat-exchanger with a wall folded in a zig-zag manner has the ends of the channels so formed closed by folding-in the material of the strip at the end of each channel so as to form a zig-zag folding with more than twice the number of partitions of the main zig-zag portion of the wall. As shown in Figs. 3-5, a strip to be folded has at one end a broken outline B1-B3-C1-C2-B4-B6 &c. Parallel folding lines A1-A2, A3-A4 are used to obtain the zig-zag formation. Inclined folding lines B1-B2, B2-B3, C1-C5, &c., leading from the corners formed by the broken outline, are utilized to fold the material in at the end of the channels and so provide additional end surfaces to which a welding bead 10 is applied, to close the slits between the folds. The chambers with which the channels communicate are separated by a partition wall 9 which is attached to the welding-bead 10 by two welding beads 11, 12 (Fig. 4). Other ways of cutting and folding the strip are described, of which Fig. 15 is an example. The partition wall (Fig. 10) may be formed in two halves 16a, 16b, each half having a bent end engaging behind projections 14, 15 formed by suitable folding of the metal strip, the slits between the folds being closed by solder 18. Closing folds may be formed at each end of the channels in the metal strip and the strip then bent to form a cylinder 27 surrounding the working chamber of a motor as in Fig. 12. The ends of the channels have a conical surface e closed at the top by a welding-bead 19. The wall 20 separating the two chambers has a conical boundary surface 21 secured to the welding- bead 19 by a welding-bead 22 of triangular section. The bottom of the channels is closed by a welding-bead 23 secured to a partition 24 by two welding-beads 25, 26. Protuberances 28 on the metal strip 27 abut against each other to prevent deformation of the heatexchanger due to the difference in pressure between the gases in the two systems of channels. The partition walls may also be fastened to the heat-exchanging element by artificial resins.

Abstract: 746,808. Guiding webs transversely. CELLOPHANE INVESTMENT CO., Ltd. June 25, 1954 [Aug. 31, 1953], No. 18708/54. Class 100(1). A travelling web or film having light-reflecting properties is registered laterally with respect to the printing roller or rollers of a rotary printing machine, particularly a rotary multi-colour printing machine, by means of one or more beams of light projected on to an edge of a web whilst passing over a non-reflecting plate. As shown, light from a lamp 14 passes through two slots in a plate 16 and forms by means of a lens 17, two images 18, 19, of the slots. If the web is correctly registered, the light of image 19 passes through an aperture 20 in a non-reflecting plate 22 and is not therefore reflected by the web 23. Image 18 is formed on the web 23 and is reflected by the web towards a photo-electric cell 25. When the web moves towards the right'the light of both images is reflected on to the cell 25 which actuates a relay which operates an electric motor to correct the registration by means of a fork engaging the web. If no light reaches the cell as a result of the web deviating to the left a second relay is energized to operate the motor in the opposite sense. Alternatively, the web may reflect light on to a glass screen, observed by an operator, who adjusts the web laterally.

Abstract: 497,684. Indicating the production of spinning-machines. BRITISH CELANESE, Ltd. July 7, 1937, No. 18890. Convention date, July 7, 1936. [Class 120 (iii)] [Also in Group XIX] In spinning - machines for manufacturing artificial yarn, the feed roller for controlling the speed of the yarn is connected with indicating means comprising a screw 17 and a rider 41 traversed thereby, the rider being tripped and returned to its starting position when a predetermined length of yarn has been fed. The rider 41 is tripped by an adjustable stop 32, a mercury switch being operated by the trip levers to close a circuit and actuate a signal. Any suitable signal may be used, for example a red light followed by a delay-action siren. Two trip-levers 49 provided with camways 48 and biassed by a spring 58, are mounted on the rider, so that normally they maintain a nut member in contact with the screw 17 to traverse the rider, and, when engaged by the stop 32, snap over and remove the nut, whereupon the rider falls, being cushioned by the plunger 65 and cylinder 67. The mercury switch is carried by the levers 49 so that it is turned when they are tripped to close the signal-circuit. A pointer 30 on the rider enables the length delivered to be read at any time on a scale 24. The spindles of a bank of machines may be divided into sections, say one hundred into five sections of twenty, and the apparatus set to operate at intervals of one fifth of the total bobbinfilling time, so that the doffing of the sections may proceed in sequence.
