Abstract: New polymeric cholesteric liquid crystal films are obtained by photopolymerisation of one or more monomers of formula I   <IMAGE> wherein R1 is H or CH3; A is -R2-, -R3O-, or -R4O-; R2 is alkylene having 3-14 methylene or alkyl- substituted methylene groups; R3 is alkylene having 2-14 methylene or alkyl-substituted methylene groups; R4 is an alkylene ether, diether or triether having a total of 3-14 carbon atoms in the alkylene linkages, provided that the alkylene linkage adjacent the carbonate moiety has at least two carbon atoms; the two Hy'S are both H or together form an additional 5,6-bond. The film is made from a mixture of (i) the monomer(s) of formula I, (ii) a photoinitiator, optionally (iii) a cross- linking agent, and optionally (iv) a further compound which is mesogenic and/or polymerisable e.g. 2-methyl- 1,4-phenylene bis(4'- hexyloxybenzoate); cholesteryl oleyl carbonate; p-methoxyphenyl p-(6- methacryloyloxy)benzoate; cholesteryl 11-methacrylamide undecanoate. The films have fixed optical characteristics, e.g. temperature- insensitive colours, and reflect specific wavelengths of light from the near u.v. into the i.r.

Title: Spraying
Inventor: HORWOOD NORMAN
IPC: B05B1/26
Filed: 1984-03-05
Abstract: Apparatus for deflecting a jet of liquid comprises a nozzle (10) having a passageway (11) leading to an orifice, adjacent which orifice are positioned sharp edged deflecting members (31,32) the sharp edges of which overlap the orifice to influence the shape of the jet. The deflecting members (31,32) may be held in position by a cap-like securing member (35) and pressure plate (33), or by screws, welding, or adhesive. The deflecting members may be located in a recess at the end of the nozzle, and may be fixedly or adjustably mounted. The nozzle and deflecting members may be of tungsten carbide. The separation of the jet deflecting or shaping members (31,32) from the nozzle (10) enables the apparatus to be made more simply and hence more economically than known devices. <IMAGE>

Title: Magnetic bubble memory system
Inventor: YOSHIDA KAZUTOSHI
IPC: G06F3/06
Filed: 1984-07-19
Abstract: A magnetic bubble memory system has a pair of data buffers (13, 16) between a magnetic bubble memory (9) and a host computer (8). Each of the buffers has a capacity corresponding to one page of the bubble memory. When one of the buffers performs data transfer with the host computer, the other buffer performs data transfer with the bubble memory. A buffer state discriminating/checking circuit (52) checks whether or not the buffers are both full, in a read operation of the bubble memory, or both empty in a write operation of the bubble memory. When the result of the check indicates that the buffers are both full or empty, a control circuit (50) connected to the output of the buffer state discriminating/checking circuit causes the operation of the bubble memory to be temporarily stopped. <IMAGE>

Title: Method for purifying exhaust gas
Inventor: KOBAYASHI YOSHIO
IPC: B01D53/68
Filed: 1985-07-23
Abstract: According to the dry method of the invention for purifying an exhaust gas, fine particles of a Ca-type absorbent such as dolomite are sprayed into the exhaust gas, and the absorbent particles absorbing acid harmful substances from the gas are collected by a dust collector (3) along with other particles in the exhaust gas. The collected particles are divided by a classifier (7) into a portion of coarse particles chiefly containing fly ash and a portion of absorbent particles not larger than a predetermined size, and the latter portion only is supplied to a hydration reactor (9). The absorbent particles in the reactor (9) are hydrated with superheated water vapor and thereby expanded, whereby an inactive shell formed on the surface of each particle by the absorption of the acid harmful substances is broken to reactivate the particles. The reactivated absorbent particles are supplied to the exhaust gas again. The acid harmful substances are therefore removable efficiently with a smaller amount of absorbent. <IMAGE>
