Abstract: ASSAY FOR INTERFERON EPSILON            Abstract of the Disclosure Disclosed is an assay procedure for detecting and quantifying interferon epsilon, a new composition of matter having selective antiviral activity on epithelial cells.  The assay comprises incubating a preparation believed to contain interferon epsilon with human keratinocyte cells and with human fibroblast cells followed by a virus challenge.  The presence of interferon epsilon is indicated if the preparation has antiviral activity on the keratinocytes but no detectable activity on the fibroblasts.  The titer of the preparation may be determined by serially diluting it, incubating the dilution with subcultures of keratinocytes, challenging the subcultures with a virus, observing the viability of cells in the cultures, and comparing the results with a standard.

Abstract: ABSTRACT    When making an unsaturated amide by hydrolysis of an unsaturated nitrile in the presence of a catalyst such as Raney copper and an oxidising agent such as copper nitrate,  by-product  formation is reduced by including a reagent selected from reducing agents and acids that are substantially non-oxidising relative to the said oxidising agent.   The preferred reagents are acidic buffers,  especially acetic acid and copper acetate.  Washing with such a buffer a Raney catalyst or other catalyst that is to be used for catalysing the hydrolysis of an unsaturated nitrile to an unsaturated amide reduces the temperature surge that otherwise occurs upon addition of the catalyst to the reaction mixture.

Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus for carrying plants periodically to a watering station while ensuring that said plants are uniformly exposed to light.  The apparatus includes at least one conveyor in the form of an endless cable disposed about a pair of spaced drums.  One of the drums is driven by a motor to cause the cable to be circulated about the drums.  The cable supports a plurality of plant hangers at spaced locations there along. Each hanger is arranged so that when a plant is suspended therefrom it is in a first orientation arranged to trip a sensor at the watering station to water the plant.  The hanger is also arranged to automatically assume a second orientation when no plant is suspended therefrom.  In the second orientation the hanger does not trip the sensor at the watering station.  The cable is arranged to be driven at a slower speed during watering operations and at a higher speed during plant loading and unloading operations.  By virtue of the movement of the conveyor through the greenhouse each plant is uniformly exposed to light reaching the conveyor.        The present invention also includes a special form of the hanger means having a locking clip, so that the hanger means will be positively held on the conveyor means.

Abstract: Abstract A frame buffer memory comprises a set of memory chips arranged in an array of n rows (planes) and m columns.  All memory chips are iden-tically addressed, a set of m, n-bit pixels being stored at each memory address with one bit of each pixel being stored in each array plane.  Each memory chip of each column is row address strobed by a common row address strobe line while each memory chip of each plane is column address strobed by a common column address strobe line.  By appro-priately strobing selected row and column address lines, data may be written to the memory array on a pixel-by-pixel or plane-by-plane basis with such data being written to individual pixels or planes or to blocks of pixels or planes.  Combinational logic within the frame buffer memory permits pixel data to be rapidly modified according to preselec-ted rules during a memory write operation prior to being written into memory.

Abstract: ABSTRACT         A first sound filter in a video IF channel of a television receiver exhibits a null response at a frequency slightly less than the 41.25 MHz sound IF carrier signal frequency.  A demodulated baseband video signal is filtered by a second sound filter which exhibits a null response at a frequency slightly less than the 4.5 MHz intercarrier sound frequency.  The first sound filter provides a nominal amount of attenuation of the sound carrier signal in the video IF channel, while conserving high frequency information as ultimately manifested in the demodulated baseband video signal.  The second sound filter assists the first sound filter to assure that sound information is adequately attenuated in the baseband video signal.

Abstract: 1,141,006. Hot water boilers; central heating systems. JUNKERS & CO. G.m.b.H. 9 Feb., 1966 [9 Feb., 1965 (2)], No. 5579/66. Headings F4A and F4U. The flow and return lines 13, 15 respectively of a circulating water heater 10 fired by a gas burner 11, are interconnected by a cross connection line 32 leading into a Venturi intake device 30 in the return line 15. The Venturi intake device 30 is bridged by short circuit pipe 34 containing a three way valve 351 controlled by a thermostat 36 downstream in the return line 15. A further cross connection line 40 connects the short circuit line 34 at the three way valve 351 with the flow line 13. In operation, when a room thermostat (not shown) calls for heat to start circulating pump 12 and light the burner 11, the water from pump 12 flows in parallel both through section 151 of return line 15 and through section 341 of short circuit line 34. The water flow through Venturi intake device 30 includes a flow of heated water from flow line 13 along cross connection line 32 past non-return valve 33 whereby the temperature of the water flowing to the heater 10 is increased to avoid condensation of combustion products from the burner 11 thereon. The water flow through pipe section 341 is diverted through the further cross connection line 40 to the flow line 13, downstream of the take off point of the first cross connection line 32, whereby an excessive temperature difference across the radiators 14 may be avoided throughout the start up period. When the water temperature at the inlet to the heater 10, as measured by thermostat 36, has achieved a sufficient value to avoid condensation of the combustion products, valve 351 is actuated to close the further cross connection line 40 and open line 34, whereby due to the great pressure drop in Venturi intake device 30, practically all the flow from circulating pump 12 passes through the short circuit line 34 and the flow from the flow line 13 through the first cross connection line 32 ceases. High and low pressure tappings 38, 39 are taken from section 151 of return pipe 15 and pipe 32 respectively, to either side of a diaphragm 19 in a pressure box 18, and used to operate a gate valve 24 in the gas supply line 25 in the event of water deficiency.
