Title: Improvements in or relating to electrical wave filters
IPC: H01Q5/00
Filed: 1936-12-23
Abstract: 488,254. Impedance networks. CORK, E. C., and PAWSEY, J. L. Dec. 23, 1936, No. 35295. [Class 40 (iii)] Two circuits tuned to the same frequency are connected by a transmission line, an odd number of quarter-wavelengths long at the frequency to which the circuits are tuned, so that one circuit presents an impedance inverse to the other, and a constant input impedance is obtained. The networks are used in band stop or separator filters, and frequencies in the pass ranges are transferred with equal time delay. In Fig. 1, the circuits 1, 2 are tuned to the sound-carrier of a television system and are spaced a quarter of the sound-carrier wavelength apart ; the filter suppresses the sound carrier ; the equivalent circuit comprises a shunt connected series tuned circuit and a series connected parallel tuned circuit, Fig. 2 (not shown). The shunt connected series tuned circuits of Fig. 1, may be replaced by series connected parallel tuned circuits, Fig. 3 (not shown), and the quarter-wavelength line may be tapped onto the parallel tuned circuits, Fig. 6 (not shown). The network of Fig. 1 may have series connected parallel tuned circuits associated with each of the circuits 1, 2, Fig. 4 (not shown). An inverse network for accepting the sound-carrier comprises shunt connected parallel tuned circuits 4, 5, Fig. 5, associated with series connected series tuned circuits 1, 2 separated by a quarterwavelength line. As applied to a separator, one of the tuned circuits of Fig. 1, is connected in shunt, Fig. 7, so that circuit 1 accepts the sound-carrier while circuit 2 and the quarter wavelength line accepts the vision-carrier ; the equivalent circuit comprises a series tuned circuit in parallel with a parallel tuned circuit, Fig. 8 (not shown). The circuits 1, 2 of Fig. 7 may be replaced by inversely connected parallel tuned circuits, Fig. 9 (not shown) ; the circuit 1, Fig. 7, may be replaced by a shunt connected parallel tuned circuit in conjunction with a quarter-wavelength line, Fig. 10 (not shown). When the network is used to suppress the sound carrier, by coupling the sound-receiver to the first tuned circuit, the sound-carrier may be obtained, Fig. 11 (not shown). The tuned circuits may be replaced by long lines Figs. 15, 16 (not shown). U.S.A. Specification 1,933,669 is referred to.

Title: Regulation of assimilable nitrogen in microbiological processes
IPC: C12P39/00
Filed: 1974-08-12
Abstract: 1514485 Regulation of assimilable nitrogen in microbiological processes SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 11 Aug 1975 [12 Aug 1974] 35435/74 Heading C6F A process for the production of micro-organisms involves growing one or more hydrocarbon (or hydrocarbon derivative, see below) utilizing microorganisms under aerobic conditions in a liquid growth medium comprising urea and essential mineral salts in the presence of a hydrocarbon (or hydrocarbon derivative) and in the presence of one or more non-hydrocarbon utilizing urease-positive micro-organisms which are capable of metabolizing organic substances produced by the growing hydrocarbon (or hydrocarbon derivative) utilizing micro-organisms. The term "hydrocarbons" as used in the Specification includes hydrocarbon derivatives which only contain carbon, hydrogen and oxygen atoms e.g. methanol. The term "micro-organism" includes bacteria, yeasts, filamentous fungi, actinomycetes and protozoa. An example is directed to the cultivation of the mixed bacterial culture designated T3 (NCIB No 11085) in the presence of methane. The culture, which is described in Specification 1467022, consists of an obligate methane-utilizing bacterium growing in association with a methanol-utilizing bacterium and species of non-methylotrophic bacteria, certain of which are urease-positive. The ureasepositive micro-organisms gradually break down urea thereby forming ammonium ions in the liquid growth medium which ions then become available to the hydrocarbon-utilizing micro-organisms as an easily assimilable source of nitrogen.

Title: Apparatus for Protecting Data Signals in Data Processing Equipment
Inventor: TSUI FRANK
IPC: H02H3/24
Filed: 1968-07-25
Abstract: 1,178,653. Computers; data stores. INTERNATIONAL BUSINESS MACHINES CORP. 25 July, 1968 [4 Aug., 1967], No. 35458/68. Headings G4A and G4C. In data processing equipment, voltage fluctuations in power supply lines indicative of a potential power failure are detected by means operable to distinguish between a catastrophic power failure in which data signals will be destroyed and a non-catastrophic power failure in which data signals may be protected, detection of a non-catastropic failure causing transfer of the contents of volatile data storage devices to a non-volatile store followed by initiation of an equipment switched-off procedure, and detection of a catastrophic failure causing initiation of the switch-off procedure immediately. In Fig. 1, D.C. supplies VNK, VK are obtained via voltage regulators SG from a filter-rectifier unit NG fed with the A.C. mains supply via relay contacts EMS. Imminent supply failure detected at US1 or US2, e.g. by overvoltage or undervoltage conditions, generate signals AS1 or AS2 to. produce signals KS1 or KS2 from logic LOG which respectively control short-circuit paths for capacitors C1, C2 (connected between the supply lines and earth) and set variable series resistors in the regulators SG to their maximum value (irrespective of the ordinary regulation control voltage RE). Production of either signal AS1, AS2 (representing faults which allow data in volatile storage to be saved) sets a first bi-stable, and production of other signals representing faults which do not allow such saving set a .  second bi-stable. If the first bi-stable is set and the second is not, the contents of machine registers (using transistorized triggers-volatile) are stored in turn into the computer's: main memory (non-volatile) addressed by a constant address generator (for the first address) and a counter. The final count and an identification of the fault are then stored in the main memory. A machine switch-off sequence then follows. If both bi-stables were set, the switch-off sequence is initiated immediately (without register saving). In either event, setting of the first bi-stable also prevents a new instruction or micro-instruction being called or executed (though the current microinstruction is completed) and presently opens the relay contacts EMS. A sudden voltage increase in a line VNK, VK due to a shortcircuit in a regulator SG is mitigated by use of a silicon-controlled-rectifier which responds to the voltage (e.g. via an amplifier) to connect a resistor across the output load. Types of machine register saved are listed.

Title: Method of packaging articles in heat shrinkable plastics film
IPC: B65B53/02
Filed: 1963-09-09
Abstract: 1,012,249. Packages. AVISUN CORPORATION. Sept. 9, 1963 [Nov. 19, 1962], No. 35531/63. Heading B8C. [Also in Division B6] In a method of packaging a lamina-like deformable article in a heat-shrinkable plastics film, the article is restrained against deformation during shrinkage of the film. In a particular application of the method a cardboard sleeve containing a gramophone record is inserted within an envelops of shrinkable plastics film, formed by folding a flat sheet and sealing along three edges or by sealing a length of tube along two edges by heat or adhesive. The sleeve is gripped at two or four of its edges, depending on whether the film is uniaxially or biaxially oriented, by a frame constituted by e.g. grippers, and heat is applied to shrink the film. The package is then allowed to cool, or cooled artificially, and the restraining frame removed. Instead of providing a complete plastics envelope, only the front face of the record sleeve may be covered by film which is secured along the edges on the back of the sleeve. The method may also be used where small items are secured to the face of a display card.

Title: Improvements in and relating to processes for preserving materials of animal origin
IPC: A23B4/28
Filed: 1929-11-23
Abstract: 338,011. Beisser, G. July 29, 1929, [Convention date]. Preserving meat, fish, &c.-Animal carcases or parts thereof are preserved by injection of a preservative medium, e.g. freshly prepared brine, into one of the vascular tracts of the flesh under a pressure exceeding the pressure in the tract during life so that the medium diffuses out of the capillary vessels into the cellular tissue, outflow of the preservative medium being prevented by carrying out the process after rigor mortis has set in and binding or clamping any larger parts of the vascular tract which may have been opened. The process may be applied to pig and other carcases or parts thereof, fowl, fish, &c. Injection may be through the aorta into the arteries or mav be into the veins or the lymphatic ducts. In dealing with carcases, the animal is preferably bled to death by opening the aorta. When rigor mortis has set in, all arteries which were opened during preparation of the animal, e.g. in removing the viscera, are bound up or clamped, and the preservative medium injected through a nozzle into the arteries, e.g. into the aortea. The nozzle a may have an olive a' at the end inserted in the aorta b. The artery is preferably drawn out a little from the surrounding flesh, so that the piece in contact with the nozzle can subsequently be cut off to avoid infection. The injection is stopped when a suitable increase in weight is obtained. When using a brine containing 53 per cent by weight of salt, 8 per cent of sugar and 59 per cent of water, the amount of brine added is 4 per cent of the weight of the flesh. The flesh may be treated whilst on a weighing- machine. Carcases may be treated with or without the hide. A brine having a salt content of over 25‹ BeaumÚ possessing high bactericidal power can be used in the process. The pressure employed must not be greater than that at which diffusion into the cellular tissue takes place to avoid tearing the membranelike capiliaries and escape of the preserving medium. The treatment of the carcase of a pig is described. Injection processes in which the carcase is treated while still warm are referred to.
