Title: Production of DNA Comprising B Hepatitis Viral Genome
IPC: C07K14/02
Filed: 1979-12-18
Abstract: The invention relates to a process for producing DNA corresponding to the DNA of B hepatitis virus. It comprises cloning in bacteria the latter DNA, previously repaired by means of the corresponding precursor nucleotides in the presence of a polymerase. The invention also relates to vectors containing said cloned DNA in their genomes. The cloned DNA is useful as a probe for detecting the presence of the virus of B hepatitis in biological samples, particularly blood or plasma. Its expression in bacteria provides a hybrid protein containing a protein fragment having vaccinating properties against B hepatitis.

Title: Memory table
IPC: G03F3/08
Filed: 1980-12-10
Abstract: A method and device for preparing a memory table for color control conditions for use in a picture reproducing machine having a table index memory are disclosed.

Title: Multi-fuel heater
IPC: F24H1/46
Filed: 1981-03-03
Abstract: A fluid heater comprises an oil or gas burner (2), a solid fuel combustion chamber (3) and fan means (6) disposed within an outer casing (1). The fluid, which may be air, enters the casing through inlets (4, 5), passes over the burner and exits the casing via outlet (8). A temperature sensor (10) at the burner inlet extinguishes said burner when the fluid temperature at the burner inlet exceeds a preset value, whereby heat from the solid fuel chamber is utilised preferentially to that from the burner. Since the solid fuel may be in the form of waste products and cheaper fuels, the arrangement provides a heater which runs preferentially on the cheapest fuel available. Further thermostats (9, 11) control the operation of the fan means. <IMAGE>

Title: Electrical apparatus for testing for straightness and evenness
IPC: G01B21/30
Filed: 1981-10-30
Abstract: An apparatus for testing for straightness and evenness comprises two vertical displacement transducers (30,31) providing electrical signals representing the relative levels of a reference surface (33) and a test surface (2), respectively. These signals are subtracted at (23) and the difference signal, representing the difference in the levels is fed via an evaluation stage (54) to an indicator (26).
