Abstract: 1,079,894. Inductive control of lifts. HITACHI Ltd. March 18, 1965 [March 24, 1964], No. 11612/65. Heading H4U. [Also in Division G1] The position of, for example, a lift cage in a shaft is determined by apparatus consisting of an energized electromagnet T1, Fig. 1, mounted on the cage, two coil carrying cores 2, 3, mounted in fixed spaced relation to, and on opposite sides of, the eletromagnet, and a plurality of pairs of metal plates (B1 B2, Fig. 2, not shown) mounted in the lift shaft so as to pass respectively through the spaces between the electromagnet 1, and the coils 2 and 3, thereby interrupting the induction of a voltage in the respective coils by the electromagnet, as the cage moves in the shaft. A switch S2, Fig. 1, connects a rectifier D1 and Schmitt trigger circuit, Q1 to Q4, to the coil 3 during upward movement, and to the coil 2 during downward movement. The plates (B2) thus gives a floor-approach warning during upward movement and the plates (B1) during downward movement, the plates (B1 being displaced from the plate (B2) in the direction of movement. The Schmitt trigger circuit operates a relay By which initiates the lift stopping mechanism.

Title: Improvements in or relating to drum dividers for percussion drills
IPC: E21B1/02
Filed: 1941-09-13
Abstract: 549,258. Winding drums. RUSTONBUCYRUS, Ltd., Sept. 13, 1941, No. 11757. Convention date, Dec. 2, 1940. [Class 78 (v)] A removable disc for dividing the winding surface of a drum into two parts, e.g. respectively for storage of cable and for winding on and off of cable, is provided with grooves and guides which minimize bending and chafing of the cable at the cross-over. The cable on the storage part of the drum enters a circumferential groove 17 extending part way round the rim of the disc, and then over a rounded corner 18 passes into a channel 20 open to the face of the disc. The channel 20 leads tangentially to the drum surface and becomes shallower toward the inner end to lead the cable gradually out against the face of a spiral wedge 22 of a radial depth equal to that of the rope. The pitch of the wedge is such as to lead the cable clear over itself where it strikes the drum surface, and so starts it on an even wind. The disc is built up of two parts 14, 15 bolted together at 16, and the parts are preferably made identical to facilitate replacement, the channel 20 and corner 18 on the rear face of the disc therein being used for receiving the outgoing part of the stored cable.

Title: Method of forming mixed superficial diffusion alloys, including chromium, on metallic objects
IPC: C23C10/14
Filed: 1951-12-03
Abstract: In a method of producing on a metallic object mixed superficial diffusion alloys of the metal of said object with at least two addition metals, one of which is chromium, using a halide vapour producing system including at least one cementing composition capable, merely under the effect of heat, of giving off halide vapours, said object and said halide vapour producing system are placed in a container, with the cementing composition out of contact with said object, and the temperature is raised to effect halide disengagement, the halide vapour producing system being such that when heated it gives off vapours of a chromium halide and a halide of at least one other addition metal and being divided into at least two distinct portions located in two different zones of said container, one of which zones is disposed above the object.  The halides of the addition metals, other than chromium, may be formed by (a) the reaction of a chromium halide with the addition metal when the latter is in the divided condition, (b) the reaction of the addition metal with a halogen acid (preferably HF) formed when chromium is diffused into the objects, (c) the reaction of alumina or zirconia in the cementing composition with chromium fluoride, (d) the reaction of an ammonium halide with the addition metal.  Alternatively, the halides may be formed in a preceding operation and introduced as such into the cementing composition.  The object to be treated may be of a ferrous metal and the addition metals comprise Al, Co, Cr, Mo, Ni, Si, Ti, W and Zr.

Abstract: 313,486. Goodyear Tire & Rubber Co., (Assignees of Clifford, A. M.). June 12, 1928, [Convention date]. Drawings to Specification. Naphthalene derivatives.-In the preparation of naphthoquinone anils the following operations are effected :-1-nitroso-2-naphthol is treated with sodium bisulphite to yield 1-amino-2-naphthol- 4-sulphonic acid, which is oxidized by nitric acid to 1.2-naphthoquinone-4-sulphonic acid.. The potassium salt of this substance on treatment with one and two molecules of aniline yields respectively 2-hydroxy- and 2-anilido-derivatives of 1- naphthoquinone-4-anil. The latter derivative on reduction with hydrosulphite is converted into 1- bydroxy-2.4-dianilidonaphthalene which is easily reoxidized to the anil. These products are antiagers for rubber.

Title: Frequency-voltage converters
IPC: H03K9/06
Filed: 1974-03-20
Abstract: 1461881 Frequency to voltage converters ROBERT BOSCH GmbH 20 March 1974 [21 March 1973] 12259/74 Heading H3A A frequency/voltage converter comprises: a first storage capacitor 159 which is charged in dependence on the output from a monostable circuit 10 and which is discharged hyperbolically through circuit 20; a second capacitor 257; and a circuit 25 which comprises an operational amplifier 252 having a series resistor 253 and diode 254 connected in its output circuit to provide a discharge path for the second capacitor and which compares the charges on the two capacitors and controls the discharge of the second in dependence on the charge on the first. At the trailing edge of each input pulse applied to input 102, monostable 10 produces a short output pulse which turns on transistor 153 to charge capacitor 159. At the end of this short pulse, the capacitor discharges through circuit 20 until the arrival of the next input pulse cuts off diodes 203 ... 207 to terminate the discharge so that the voltage across the capacitor 159 is dependent on the input pulse rate. During the next input pulse, diode 260 is also cut off and the voltage across capacitor 159 is transferred to capacitor 258 by the amplifier 252. At the termination of this pulse, diode 260 again cuts off leaving capacitor 257 charged to a voltage dependent on the input pulse rate and monostable 10 produces another output pulse which recharges capacitor 159 as before. In order to minimize the current drain on the supply capacitor 159 is charged from a larger capacitor 158. Diode 266 provides temperature compensation.
