Title: Opto-electric device for switching on power-consuming equipment
Inventor: WATERTON NICHOLAS
IPC: H03K17/94
Filed: 1987-11-10
Abstract: A surgical mirror demisting unit, warm air hand dryer or the like has two resistive light detectors 6 and 7 mounted at the bottom of respective sighting tubes 8 and 9 close the outlet 3 of a hot air blower 2. The detectors are series connected between voltage rails and their common junction is a.c. coupled to an amplifier (11 Figure 2) and comparator (13 Figure 2). The blower is turned on when an object e.g. surgical mirror 30 shadows from ambient light a part of the unit such that the output of one detector changes relative to the other. This causes an output to the amplifier and starts a timer (15 Figure 2) which turns on the blower 2 for a preset time. <IMAGE>

Title: Making filter cigarettes
Inventor: OESTERLING ERWIN
IPC: A24C5/33
Filed: 1991-03-18
Abstract: Filter cigarettes 38a, 38b are mass-produced in a machine wherein parallel groups of coaxial plain cigarettes 7a, 7b and filter plugs 16 are moved at right angles to their axes through a first station wherein their components are connected to each other by uniting bands 29, thereupon through a second station wherein the resulting filter cigarettes of double unit length are severed midway across their filter plugs to yield pairs of filter cigarettes of unit length which advance in two rows a and b and are mirror images of each other, and through a third station wherein the filter cigarettes of one row b are turned end-for-end and placed between successive non-inverted filter cigarettes. The mutual spacing of groups, filter cigarettes of double unit length and/or of filter cigarettes of unit length is reduced at least once, preferably twice, namely the first time between the first and second stations and the second time at the third station. This results in the formation of a single row of filter cigarettes wherein the spacing between neighboring cigarettes is zero or close to zero. <IMAGE>

Title: Multivalent antigen-binding proteins
Inventor: KING DAVID JOHN
IPC: C07K19/00
Filed: 1992-02-11
Abstract: A multivalent antigen-binding protein comprises a first Fv fragment bound to at least one further Fv fragment by a connecting structure which links the Fv fragments to each other but which maintains them spaced apart such that the protein is capable of binding to adjacent antigenic determinants. Typically the connecting structure comprises a spacing polypeptide sequence, which may be about 3 to 16 amino acids in length, connected to a linkage unit which may be a synthetic chemical linker, e.g. a maleimide linker, or is a polypeptide sequence leading from the spacing sequence. In a particularly preferred embodiment the multivalent antigen binding protein comprises a VH domain having attached to its C-terminal end a V-C joining sequence and an antibody hinge sequence. Preferably one or more of the Fv fragments is a single chain Fv (scFv). The proteins are preferably prepared by recombinant DNA techniques and are useful for in vivo therapeutic and especially diagnostic applications.
