Classes 38 (3) and 38 (5). In a control system for say a battery electric vehicle wherein a periodically operated switch 3, Fig. 3, shunted by a capacitor 4 is connected between a source 1 and a D.C. motor 2, a series inductor 5-7 is employed to reduce the discharge current from the capacitor and also to transfer the discharge energy to the motor. A rectifier 8 may be used to provide a path for the induced energy from the inductor. Other circuit arrangements are also given. The switch 3, whose on-off ratio may be varied is operated by a cylindrical cam 47, Fig. 12, driven by a second electric motor 57 at a speed of say 10-20 R.P. sec. The cam has a varying cross-section along its length and is positioned along shaft 55 by a control lever 53.

The levulinic acid (I) is condensed with phenylhydrazine, a substituted phenylhydrazine, alkyl hydrazine or heterocyclic hydrazine and the resulting hydrazone (II) is cyclised by heating to give 2-phenyl(-substituted phenyl, -alkyl, or -heterocyclic)-6-methyl pyridazinone (III), which on treatment with phosphorus pentachloride yields a mixture of 2-phenyl (-substituted phenyl, -alkyl, or -heterocyclic)-4 - chloro - 6 - methyl - 3 - pyridazone (IV) and 2-phenyl(-substituted phenyl, -alkyl, or -heterocyclic)-6-methyl-3-pyridazone (V).  Further treatment of (V) with phosphorus pentachloride yields an additional amount of (IV) which, on treatment with methyl alcoholic ammonia at elevated temperature gives 2-phenyl(-substituted phenyl, -alkyl, or -heterocyclic) - 4 - amino - 6 - methyl - 3 - pyridazone (VI).  The sulphanilamido compound (VII) is prepared by condensing (VI) in the presence of pyridine with N-acetylsulphanilyl chloride or p-nitrobenzenesulphanilyl chloride, and is then converted by hydrolysis or reduction into the product 2-phenyl(-substituted phenyl, -alkyl, or -heterocyclic) - 4 - sulphanilamido - 6 - methyl - 3 - pyridazone (VIII).  Examples are given of the preparation of: (1) 2-phenyl-4-sulphanilamido-6-methyl-3-pyridazone and (2) and (3) 2-(41-nitrophenyl)-4-sulphanilamido-6-methyl-3-pyridazone. In (2) the nitro group is introduced by using p-nitrophenylhydrazine to react with the levulinic acid, and in (3) it is introduced by nitrating compound (IV), (V) or (VI).

Abstract: 643,747. Coating paper webs. TIME, Inc. Nov. 13, 1947, No. 30226. Convention date, Nov. 16, 1946. [Classes 96 and 140] A method of coating a paper web comprises uniformly distributing a viscous coating material over moving surfaces and applying it to the web whilst maintaining the vapour pressures of the coating material and the surrounding atmosphere substantially equal to prevent evaporation of moisture from the coating material. The material is distributed over a series of rollers, one or more being made of heat conductive material and being cooled to a temperature below the dew point of the atmosphere. The invention may also be carried out by regulating the humidity of the atmosphere surrounding the distributing rollers by the introduction of steam or by housing the machine in an air conditioned enclosure. The method may comprise both humidifying the atmosphere and cooling one or more of the rollers.

Abstract: 818,834. Frequency modulation. STANDARD TELEPHONES & CABLES Ltd. Sept. 27, 1957 [Oct. 4, 1956], No. 30328/57. Class 40 (5). A frequency-modulated oscillator comprises valves connected in parallel to a common tuned anode circuit L1, C1, C2, C3 both directly and inductively coupled to a second tuned circuit C4, C5, L2 connected between control grids of the valves so that oscillation maintaining and quadrature phase feedback are both applied to the grids, and modulation applied in push-pull to the same grids varies the relative mutual conductance of the valves and the phase of the vector sum of the two outputs, to produce frequency variation of the oscillator. A resistance R is inserted in the grid tuned circuit to increase its bandwidth. The mean frequency may be altered or stabilized by differential control voltages applied in series with the modulation. A rectifier G and smoothing circuit R-C connected to the anode circuit may apply negative feedback in series with the frequency control differential voltages to stabilize the amplitude of the oscillations generated.

Abstract: 375,183. Type-barm a king machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) Nov. 3, 1931, No. 30430. [Class 100 (iii).] Assembling, clamping, and aligning matrices.- A hand composing stick for holding a line of matrices in casting position, independently of the first elevator, is adapted to be yieldingly held in a fixed frame, such as the vice-frame, and to be moved bodily therein to effect alignment of the matrices. The first elevator A, Fig. 1, is locked out of action in its upper position by means of a pivoted-latch-member P. When the elevator is so held, the vice automatic stop-rod G is operated by a lever D<3> and a shoe a2 on the elevator. The hand composing-stick comprises a bottom wall J<1>, Fig. 9, a side-wall J<2>, and two end-walls J3, J<4>. A matrix retaining-bar J<5>, which is of V-shape in cross section, is hinged to one end-wall, and can be swung over to engage with the V-shaped notches in the upper ends of the matrices, in which position it is held by a spring latch. The stick, which is provided with a handle J<10>, is inserted in the machine between the vicejaws, and is supported by means of lugs J<6> on the end-walls, which rest on the top of the vice-cap D<1>, Fig. 1. The stick is resiliently held down on the vice-cap by a bolt J", which is provided with a handle J<13>, and carries an. arm J<12>, which can be turned under the flange D4 of the vice-cap. A spring surrounding the bolt holds down the stick, which is raised by the justifying-bar E, in order to align the matrices against the aligning-rib on the mould. Prior to the aligning, the left-hand vice-jaw C<1>, shown in plan in Fig. 2, is pressed against the stick by the movement of the known wedgebar O, and the right-hand jaw C<2> is thereby forced against a fixed stop-pin C<3>. The known pump-stop lever Q is at the same time actuated by the jaw C<2> to permit the casting to take place. One end-wall of the stick is yieldingly mounted, so that the movement of the jaw C<1> also clamps the matrices in the stick. A retractable interponent R is provided for insertion between the jaw C<2> and the stop C<3>, to compensate for the thickness of the end-wall of the stick, when the stick is not in use. The matrix-retaining member J<5> may be adapted to engage the upper ears of the matrices. The end-wall of the stick may be rigidly mounted, and the matrices clamped therein by a wedgemember, which is driven upwards by the justifying-bar.
