Title: Improved process for the production of single cell protein
IPC: C12N1/00
Filed: 1980-01-31
Abstract: A process for the production of prokaryotic, particularly bacterial, single cell protein includes a step in which whole and/or ruptured micro- organism cells are treated with an oxidising agent or are subjected to other oxidising means. The preferred oxidising agent is hydrogen peroxide. The product of the process has a number of advantages over known prokaryotic single cell protein, most important being that its use alleviates difficulties of reduced feed intake, reduced live weight gain, poor feed conversion ratios and liver damage experienced when single cell protein is fed to domestic fowls in high dietary inclusions.

Title: Flow rate sensor
IPC: G01F1/10
Filed: 1980-04-29
Abstract: A sensor of the rate of flow of a fluid through casing (111) in direction (113) has a freely rotating rotor (115), on which the fluid impinges. The inside surface of the hub of the rotor (115) is formed by alternate reflective (144) and non-reflective (146) surfaces. Light from a source (120) impinges on these surfaces and is either reflected back to a light detector (119) or not depending on which of the surfaces (144, 146) the light falls on. Pulses produced by the detector corresponding to the interruption of light to it, are used to indicate the rate of flow. The sensor is combined with rotor (112) which drives the fluid (ambient air) through casing (111). Alternatively the freely rotating rotor may chop the light sent from source to detector; or it may be combined with a centrifugal blower and the freely rotating rotor may be in a recess. <IMAGE>

Title: Electrical connection of multiconductor cables
IPC: H01R12/61
Filed: 1980-05-23
Abstract: In connecting flat multiconductor cables, one cable is placed atop another to provide a matrix of zones 26-50 in which connections may be made of any conductor of one cable to any conductor of the other cable. Selection is made of one zone 26 and it is perforated at 160. An insulation-piercing connector is inserted through the perforation and crimped to provide an electrical connection between the pair of cable conductors in registry with the selected zone. Selection of further zones for perforation and connector insertion is made progressively from those zones which do not have in registry therewith any conductor which was in registry with any previously selected zone. Apparatus 158 for implementing preferred connection zone selection precludes use of connecting zones other than a singular zone 26 for connection of one conductor pair and compels use of a selective few zones individually for connection of respective other conductor pairs, thereby lessening connection error likelihood.   <IMAGE>

Patent GB-2086545-A (GB)
Title: A metering valve for a lubricant or a similar medium
IPC: F16K25/02
Filed: 1981-11-03
Abstract: The metering valve prevents impurities contained in the medium to be supplied from clogging a throttling point (17) provided in the valve and from distorting the desired volumetric flow set in the valve. Two pistons (3,8) are mounted axially displaceably in a frame (1) of the metering valve to form a throttling point together with an adjustable throttling element (14) fastened in the frame. As the pressure in the supply pipe rises, causing the pistons to be displaced towards the throttling element, there is an open flow connection from an inlet (4) of the valve to an outlet (5) through the throttling point, but as the pistons are displaced away from the throttling element, when the supply pipe pressure falls, one (8) of the pistons closes the inlet and the other piston (3) presses a medium dose (12) from chamber 2A through the throttling point. As said other piston (3) is displaced away from the throttling means, the throttling point is widened so that said medium dose rinses off the impurities accumulated in the throttling point. In this way a self-cleaning, continuously feeding metering valve provided with an adjustable throttling point is provided. <IMAGE>

Title: Black shading correction
Inventor: GROVES PHILIP RANGECROFT
IPC: H04N5/217
Filed: 1982-09-09
Abstract: The apparatus comprises means for monitoring the signals produced from each of a plurality of picture elements, means for comparing each monitored signal with a reference to provide an error value for each picture element, means (10, 12, 14) for calculating a correction signal from the error values and control means for applying the correction signal to correct images. The black shading occurs as a result of non-uniform illumination of bias lighting within a camera tube. Preferably, calculation of the correction signal includes multiplying adjacent error values (value 1, value 2) by a respective reference signal (V REF. 1, V REF. 2) which has a frequency equal to half the frequency of occurrence of the picture elements whose values are being multiplied. The reference signals (V REF. 1, V REF. 2) are in anti-phase with each other and the multiplied values are summed. Calculation of the correction signal thus includes a smoothed interpolation arising from the scaling function of digital to analogue converters. <IMAGE>
