Title: Apparatus for tolling or chiming bells
IPC: G10K1/34
Filed: 1920-09-20
Abstract: 171,835. Greening, W. A., and Rowe, W. A. Sept. 20, 1920. Bell signalling systems.-Electromagnetic apparatus for tolling chiming bells, in which a make and break device controls the excitement of the electromagnet R, Fig. 4, giving the impulses to the clapper or striker O of a bell, comprises a second electromagnet D excited by the clapper at the extremity of its backward swing, and a swinging arm A carrying an armature E attracted by the magnet D when energized to break a contact C normally kept closed by a spring B, thus breaking the circuit of the electromagnet R. The cycle of operations is automatically repeated indefinitely. The apparatus is preferably arranged so that all the parts except the striker and its associated electromagnet R are placed at a distance from the bell. In order to regulate the frequency of the strokes of the bell, the swinging-arm A may carry a knifeedged plate H, Fig. 1, to engage with projections G1 on a number of levers F1, rocking about a common axis and controlled by springs G, so that the arm A is normally held back from closing the contact C and operating the bell. A revolving drum I carries surfaces, one corresponding to each lever F1, and having different numbers of teeth J2 which engage other ends of the levers F1, and move the projection G1 out of engagement with the plate H, so that one stroke of the bell is given corresponding to each tooth. The bell thus receives a number of strokes per revolution equal to the number of teeth on the drum surface in use. A shaft K has flat surfaces L, L1, - -, one for each lever arranged in staggered relation below its periphery, whilst the remainder of the shaft has its full diameter, so that only one, for example F1, Fig. 1, or non of the levers is in position for engagement with the plate H. A handle M attached to the shaft K moves over the indicator dial N.

Title: Improvements in or relating to a process for producing mono-alkylbenzenes and the mono-alkylbenzenes resulting from said process
IPC: C07C2/68
Filed: 1947-10-09
Abstract: Mono-alkyl benzenes are produced by supplying simultaneously and in parallel flow to each of two alkylators 1 and 2 containing alkylation liquor including an aluminium chloride-aromatic hydrocarbon complex, a stream of benzene, introducing to alkylator 2 a gaseous olefin, e.g. ethylene, propylene or butylene, in such an amount as to maintain a reaction temperature of 80-100 DEG  C., and to alkylator 1 an amount of said olefin in excess thereof, continuously withdrawing liquor from alkylator 1, cooling, contacting with olefin off gas from 1 and 2, withdrawing alkylated liquor from 1 and 2, separating it into benzene, mono-alkyl, and poly-alkyl benzene fractions, and returning poly-alkyl benzene to alkylator 2.  A promoter, e.g. 0.3 per cent hydrogen chloride or ethyl chloride, may be added to the dry benzene.  Each alkylator operates at 80-100 DEG  C. and substantially atmospheric pressure, and is connected to a separator which separates and returns the catalyst complex.  At equilibrium, 10-30 per cent of the total olefin is fed to alkylator 2.  The off-gases are scrubbed with cooled reaction liquor, at 40-50 DEG  C., with benzene, and finally with poly-alkyl benzene.  Alkylate liquor from the separators is water and alkali washed prior to fractionation.  Fresh aluminium chloride is added to the circulating complex in both alkylators.

Title: Improvements relating to oscillation generators
IPC: H03K4/86
Filed: 1936-10-09
Abstract: 464,257. Valve generating circuits. LORENZ AKT.-GES., C. Oct. 9, 1936, No. 27469. Convention date, Oct. 9, 1935. [Class 40 (v)] A condenser C1 is charged from a source V over a resistance R1 and, when it attains the ignition potential of a glow lamp G1, discharges. Should the potential V vary, the time of charging the condenser will vary, and the frequency of the oscillation will alter. To compensate this, an alternating voltage is derived from the oscillations and applied to bias the glow lamp G1. The oscillations are applied to an amplifier R whose output is transformer coupled to the transformer T2 so that the potential applied to the glow lamp Glover transformer T2 is such as to increase its ignition potential. Should the source V vary, the anode voltage of R alters, to produce a change in the amplification, so that the voltage applied over T2 increases or reduces the ignition potential of Gl according as the variation in V reduces or increases the charging time of C1.
