Abstract: 1,110,268. Testing cigarettes. HAUNIWERKE KÍRBER & CO. KOMM.-GES. 17 May, 1966 [15 June, 1965], No. 21891/66. Heading A2C. In testing the presence, absence, or filling of a component of an axially aligned unwrapped cigarette-filter group 1 travelling transversely to its axis, the test is effected immediately prior to wrapping. Double length filters F are assembled at station U1 between pairs of cigarette lengths Z in the grooves of a drum 4. The assembled groups run over a pair of guides 12 to a station U2 where a connector sheet 16 is applied from a drum 18, the group being wrapped between a drum 80 and a rolling surface 86 immediately after transfer from the drum 4. The guides 12 have slots for feelers 30. The feelers may be spring-biased or weighted to press against a component to be tested. Should the component be faulty or absent, the feeler moves in a direction to activate the switch 38 or a photo-electric device, Fig. 3 (not shown), so as to cause the subsequent rejection of the group. In an alternative embodiment, Fig. 4 (not shown), the testing is effected at the station U3 after the connecter sheet 16 has been applied, but before wrapping takes place.

Title: Improvements in press-button switches
IPC: H01H13/26
Filed: 1938-07-25
Abstract: 517,341. Press-button switches. LIST. H. July 25, 1938, Nos. 21966 and 21967. Convention dates, Oct. 12, 1937, and Oct. 16, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 3, 1939.] [Class 38 (v)] A press-button switch is so constructed that the pressure necessary to actuate it increases up to a certain point in the travel of the contactpiece and then suddenly diminishes, so as to secure rapid closing, and the increase in pressure can be regulated. For this purpose the plungerbody of the switch is formed with transverse bores in which are balls 18 pressed outwardly by springs 19. At a certain point in the travel of the plunger these balls are pressed inwardly by an inclined portion of the casing thus offering a resistance to the motion of the plunger until they are past the constricted portion of the casing. To regulate this resistance a conical member 27 is arranged to slide in the plunger without rotation, so as to press the inner ends of the springs 19 outwardly. This is effected by turning the press button 16, which is secured to the plunger so as to rotate without longitudinal motion by means of a screw 25 and is provided with a screwed extension 24 engaging the member 27. The contacts 7a, 7b are bridged by a piece 5 rotatably mounted on the plunger Several pairs of contacts in parallel are so arranged that one pair is always bridged first, thus preserving the others from damage by sparking. In a modification the helical screws 19 are replaced by a hairpin-spring, the tension of which can be regulated by a screw pressing on its bent portion. The resistance of the balls to the motion of the plunger can also be adjusted by making the constricted portion of the casing of different diameters in different axial planes and turning the plunger until the balls are in the plane required. The contact-disc 5 may be replaced by a ball rotating freely in a cage attached to the plunger. The Specification as open to inspection under Sect. 91 describes a switch without the pressure device. This subject-matter does not occur in the Specification as accepted.

Title: Recovery of phenols
Inventor: JACOBS DAVID IAN HUTCHINSON
IPC: C07C39/08
Filed: 1952-09-10
Abstract: A process for the production of resorcinol by the catalytic cleavage of a reaction mixture containing meta-di-isopropylbenzene hydroperoxide derived from the oxidation of meta-di-isopropylbenzene comprises decomposing by the action of heat the material contained in the cleavage reaction product which is less volatile than resorcinol and recovering the additional quantities of resorcinol and the meta-isopropenylphenol so formed.  The heat treatment may be conducted in presence of an acid catalyst or, alternatively, the cleavage reaction product is treated to remove or neutralize cleavage catalysts and stripped of low-boiling materials before being subjected to heat treatment.  The heat treatment is also preferably conducted at 200-400 DEG  C. at super- or sub-atmospheric pressures and in presence of a high-boiling inert diluent (preferably boiling at or above 200 DEG  C., e.g. tri-isopropyl- or 1 : 2 : 4-trichlorobenzene; isopropyl-, methyl-, chloro- or bromonaphthalene; a gas oil fraction; or a mixture thereof), the heat-treated cleavage reaction product being distilled and the resorcinol and meta-isopropenylphenol recovered from the distillate preferably by crystallization and filtration, or by distilling directly into water. The heat treatment and distillation are preferably conducted simultaneously, and the proportion of high-boiling inert diluent is preferably adjusted so that the distillate is not saturated with respect to resorcinol while still above the temperature at which crystallization takes place.  Further quantities of resorcinol may be recovered from solution in the inert diluent mother-liquors by extraction with water; meta-isopropenylphenol is also recovered by extracting the resorcinol-free inert diluent with an aqueous alkaline solution. Mixed resorcinol/meta-isopropenylphenol phases are separated (1) by extraction with a solvent, e.g. benzene, toluene, methyl-naphthalene, chloroform or carbon tetrachloride; or (2) by partition between two immiscible solvents, e.g. water and one of the solvents in (1).  The resorcinol, after separation from the meta-isopropenyl phenol, may be further purified by redistillation, or by sublimation.
