Title: A method of determining whether a desired logical relationship between a number of elements exists or not
IPC: H03K19/16
Filed: 1961-09-22
Abstract: 995,627. Logic circuits. SIEMENSSCHUCKERTWERKE A.G. Sept. 22, 1961 [Sept. 22, 1960], No. 34117/61. Heading H3B. To determine whether a desired logical relationship exists between a number of inputs, each input is applied to a separate winding 14, 15, 16 magnetically linked to two magnetic cores, a premagnetizing current, having a value dependent upon the relationship to be determined, is fed to a control winding 13 also linked to both cores, first and second operating voltages are applied across respective operating windings 11, 12, magnetically linked one to each core, and a common resistance 17, so that the voltage developed across resistance 17 is indicative of whether or not the function exists. Source 2 supplies a direct voltage of square pulse waveform, the duration of each pulse being equal to the interval between pulses, and the two outputs being 180 degrees out of phase. The inputs to windings 13, 14, 15 and 16 are arranged to produce magnetic fields which are integral multiples of the field H 5  required to saturate each core. By selecting the value of the premagnetic field due to winding 13 the circuit can be made to perform any one of a large number of logical functions, examples of which are tabulated in the Specification. Inverted input signals are applied to produce a negative field intensity, while non-inverted signals produce a positive field intensity. When the inputs satisfy the selected function a constant direct voltage is obtained across resistor 17. Otherwise the pulses from 21, 22 are used to positively saturate the cores and substantially no output is produced.

Title: Improvements in or relating to a new piperazine derivative and salts thereof including penicillin salts thereof
IPC: A23K1/16
Filed: 1955-11-29
Abstract: The invention comprises 2,5-diphenyl-piperazine, and the acid addition salts, including penicillin salts, thereof, and the preparation thereof by hydrogenating 2,5-diphenyl-pyrazine or a 2,5-diphenyl-dihydro-pyrazine in the presence of a hydrogenation catalyst and an inert solvent for said pyrazine.  The hydrogen catalyst is preferably a palladium-carbon catalyst and the inert solvent is preferably formic acid.  The acid addition salts may be derived from an organic or mineral acid, the hydrochloride and acetate salts being referred to specifically.  The penicillin salts may be derived from penicillin F, G, K or X, the 2,5-diphenyl-piperazine combining with 2 mols. of the penicillin used.  A suitable method for the preparation of the penicillin salts is by double decomposition using a water-soluble salt of 2,5-diphenyl-piperazine, e.g. the acetate salt, and a water-soluble salt of penicillin, e.g. the triethylamine salt, in an aqueous solution.  The double decomposition process may be modified to use other solvents in which the salt of piperazine is soluble and an alkali or alkaline earth metal salt of penicillin or a salt of penicillin with any organic base.  It is also possible to form a penicillin salt of 2,5-diphenyl-piperazine by reacting penicillin acid with 2,5-diphenyl-piperazine in an organic solvent for the reactants and isolating the required penicillin salt, e.g. by evaporation or the addition of another solvent.  In the examples, 2,5-diphenyl-piperazine is prepared by hydrogenating 2,5-diphenyl - 3,6 - dihydro - pyrazine and 2,5 - diphenylpyrazine in the process of palladium/carbon catalyst, and is converted into the hydrochloride and bipenicillinate G salts.ALSO:Penicillin salts of 2, 5-diphenyl piperazine are employed in stock raising.  An example is concerned with the preparation of colourless, prismatic needles of the bipenicillinate G of 2, 5-diphenyl piperazine of water solubility 0,35 parts per thousand.ALSO:A therapeutic composition comprises a salt of 2,5-diphenyl-piperazine with a penicillin and a carrier.  The composition may be in the form of a suspension, e.g. in distilled water, in a saline solution, or in an aqueous propylene glycol solution, or the composition may be formed in an oil, e.g. in arachis oil, sesame oil, cottonseed oil or other suitable triglyceride. Other agents which may be present are stabilizing, thixotropic, and wetting agents, and viscosity modifiers.  The composition may be in the form of compressed tablets or granules. The composition is suitable for application to plants and for addition to animal feedstuffs when a liquid carrier for the salt is used.  Particular penicillins referred to from which the salts may be derived are penicillin F, G, K and X, and mixtures of such salts may also be used.

Title: Frame count cuer for continuous photographic film printer
IPC: G03B27/46
Filed: 1972-07-25
Abstract: 1362347 Photographic printers BELL & HOWELL CO. 25 July 1972 [1 Sept 1971] 34658/72 Heading G4H  A frame-count cuer 12 for a photographic film printer 10 wherein scenes on a film 16 are copied on to a film 14 with individual intensity and hue corrections obtained from a prerecorded tape 30, comprises means 34 for reading a tape 32 on which is recorded the length of each scene of film 16, means 36 for storing the length of the scene being printed, a counter 40 receiving pulses from a generator 24 connected to the film drive 22, 23 to determine the amount of film which has passed through the printer, and a comparator 42 which produces cue signals when the contents of 36 and 40 are equal to control the reading of the tapes. Film length is measured in feet and frames provision being made in counter 40 for altering the frames/foot ratio to accommodate different types of film (Figs. 2, 3, not shown). The length of each scene is recorded in BCD form on 8 rows of tape 32: rows 2, 3, 4, 6 for footage and rows 7, 8 for the number of frames. Row 1 contains a hole in channel 8 to indicate the start of a new scene, and row 5 is used for synchronization: the presence of a hole in this row causes a sensor 38 to stop the printer. Lighting correction data for each scene is recorded on rows 1-4 of tape 30:row 1 indicates a new scene, and rows 2-4 contain red, green and blue hue information. The data on this tape is fed to a controlled light source 20 which includes primary colour light vanes adjustable to intercept a selected portion of the light in respective primary colour light beams in accordance with the corrections required for the scene being printed, and light valves which store the corrections required for the following scene and which are to be passed to the vanes at the next cue signal. At the end of a scene the count in 40 becomes equal to the last stored value in 36, causing 42 to emit a cue signal which causes reader 34 to step tape 32 through 8 rows to obtain the length of the next scene for store in 36. The cue signal also causes light source 20 to transfer the data stored in the valves to the vanes, and causes reader 28 to transmit the data for the nextbut-one scene for storage in the valves. If counter 40 counts from the beginning of each scene (rather than the beginning of the film) then it is reset by the cue signal, and the next scene is then copied at aperture 18.
