Title: Improvements in or relating to electrically-operated hoists
IPC: B66B9/16
Filed: 1960-06-17
Abstract: 896,230. Controllers. ZEPPENFELD, G., [trading as ALOYS ZEPPENFELD]. June 17, 1960 [July 2, 1959 (2); Dec. 22, 1959], No. 21397/60. Class 38 (3). [Also in Group XXX] An electrically-operated hoist is stopped at preselected levels by including in the motor or control circuit an elongated conductor on which insulating members are adjustably positioned to break contact between the conductor and a collector. As shown, the hoist cable 4 is used as the conductor, and is fitted with insulating sleeves 8, 8a. The collector comprises an insulated roller 12 or alternatively a carbon bar (Fig. 3, not shown). The insulators 8 are short enough to be over-run so that the motor may be re-started by operating a push-button, but the final one 8a is longer to act as a safety limit switch. An additional limit switch comprises an insulating cone 14 or ramp on which the cable runs if other limits are ineffective. The collector is mounted on pivoted arms 10 arranged so that should the cable become slack, e.g. if the platform is obstructed during lowering, a switch 22 is operated to first stop and then reverse the motor. The motor will stop again when the cable has tightened. In an alternative arrangement, Fig. 5, not shown, the elongated conductor comprises a rail secured to the hoist framework and is contacted by a collector carried by the platform. Insulating sliders serve the purpose of the sleeves 8, 8a and the top part of the rail is of insulating material as a safety limit.

Title: Gas-and-liquid-contact apparatus
IPC: F28C1/02
Filed: 1960-06-17
Abstract: 930,686. Contacting gases with liquids. CARRIER CORPORATION. June 17, 1960 [June 24, 1959], No. 21466/60. Class 55 (2). In a gas-and-liquid-contact apparatus comprising a packing 9 (Fig. 1), through which a gas stream (e.g. air) is passed by means such as a fan 15 end over which liquid is distributed by means such as a rotating header 11, the packing 9 comprises thin partition walls, at least certain of which are undulated to engage the other walls at spaced intervals (Fig. 2) and defining cells 19 open at each end so that liquid passed over the packing 9 can flow therethrough and maintain liquid films on the cell walls in contact with gas in counterflow, each cell 19 being cut an angle (Fig. 3) to form elongated openings, the respective ends of substantially all of which lie substantially in the same respective planes, so that bridging of the liquid in the cells 19 is broken. Preferably, the packing 9 is made of undulating walls 21 separated by substantially flat walls 20 (Fig. 2), which are substantially parallel, terminating at the upper end of the elongated openings in one form and at the lower end in another form. The cells 19 may be of such a size that liquid such as water can bridge the walls. A method of fabricating a packing 19 comprises the steps of corrugating a partition wall to the peaks of which an adhesive is applied, urging a substantially flat wall into contact with the said peaks, cutting an edge of the corrugated facing on a bias, applying an adhesive to the peaks in the exposed surface of the facing cutting the facing into suitable lengths, and stacking the so-cut facings so that the exposed peaks contact the flat wall of an adjacent facing. Pressure is then applied to the stacked corrugated facings. An impregnant is sprayed on the corrugated facing and cured. Air can enter through louvres 4 (Fig. 1), the liquid such as water being collected in a sump 5 and recirculated by a pump 13 to the rotating header 11. The level of the water is maintained by means of a ball valve 7.

Title: Methods of and means for depolarizing primary cells and batteries
IPC: H01M6/04
Filed: 1935-07-29
Abstract: 462,462. Supply systems for galvanic batteries; converting. MULLER, H., and STEIN, W. July 29, 1935, Nos. 21520 and 21521. Convention dates, July 31, 1934 and Feb. 28, 1935. [Classes 38 (ii) and 38 (iv)] A primary battery is depolarized by an electric current the circuit of which contains devices for cutting off the current when depolarization is complete and for starting the current when the battery voltage falls. In the arrange. ment shown in Fig. 1, the battery 6 to be depolarized is connected to the cathode and anode of a rectifier 5, the heating filament of which is connected to a winding of a transformer 1 which is so dimensioned that when the battery is depolarized and giving its full voltage the current in the heating filament of the rectifier is at a minimum. A regulating resistance 7 is included in the filament circuit. When the battery voltage falls a current begins to flow through the rectifier from the transformer 2 which is in series with the transformer 1. The load on the transformer 2 reduces its primary voltage and thus increases the voltage of transformer 1 which increases the filament current in the rectifier 5. The anode current is thus further increased and continues to increase until it has acquired the value necessary for depolarization of the battery. Fig. 2 shows another arrangement in which the depolarizing current for the battery 6 is obtained from a grid-controlled thermionic valve 8 which receives current from a transformer in an alternating current circuit. The grid 11 of the valve is connected to a tapping on the battery, and is thus kept at a sufficiently negative potential relatively to the filament to prevent current from flowing through the valve. When the battery voltage falls the voltage on the valve grid also falls and allows current to pass through the valve into the battery. Figs. 3 and 4 show other arrangements for depolarizing a primary battery 6 in which the depolarizing current is started and stopped automatically by means of transformers 12 having variable reluctance. The transformer shown in Fig. 3 is provided with a winding 15 connected to a regulating resistance 14, and the transformer shown in Fig. 4 has an adjustable magnetic shunt 17. Specification 431,898 is referred to. The Specification as open to inspection under Sect. 91 describes the arrangements shown in Fig. 5 and 6 (both Cancelled), in which a lamp 20 is connected in parallel with the battery 21 which receives current from a rectifier 19 supplied from an alternator 18 or transformer 23. If the current from the rectifier fails the lamp takes current from the battery. This subject-matter does not appear in the Specification as accepted.

Title: A method of improving the electrical conductivity of thin nonmetallic layers appliedto bases
IPC: H01B1/00
Filed: 1960-06-24
Abstract: 887,548. Resistive coatings. BALZERS AKTIENGESELLSCHAFT FUR HOCHVAKUUMTECHNIK UND DUNNE SCHICHTEN. June 24, 1960 [June 30, 1959], No. 22195/60. Class 37. [Also in Group XL (a)] The electrical conductivity of a non-metallic layer deposited on a base is permanently improved by exposure to an electric glow discharge. In the apparatus shown, glass plates 4, 4<SP>1</SP>, or plates of synthetic material such as polymetacrylic ester or polystyrene, are first cleaned in a glow discharge of 10 to 300 milliamps in a pure oxygen atmosphere at a pressure of 10<SP>-1</SP> to 10<SP>-3</SP> mm. Hg. The plates are then provided with layers of predominantly indium oxide by the evaporation of an indium-cerium mixture contained in a crucible 5. Indium oxide, zinc oxide or tin oxide layers may be produced by evaporating pure indium, zinc or tin. The evaporation step is carried out in an oxygen atmosphere at a pressure of 10<SP>-3</SP> to 10<SP>-5</SP> mm. Hg. The glow discharge to improve the electrical conductivity of the layers is then carried out in the same atmosphere, the current intensity being between 5 and 100 milliamps. The glow discharge treatment may, however, be carried out during the deposition step. A test-plate 16 is provided for examining optical transmission and reflection properties and electrical conductivities. The glow discharge may be automatically interrupted at the appropriate moment. The glow discharge electrode 9 may be of aluminium or of the same metal as chemically bound in the layer to be treated. A rotatable blind 11 is provided in front of the crucible 5. The gas atmosphere during the glow discharge treatment may be nitrogen, where the treated layer is a nitride, or hydrogen sulphide where it is a sulphide. The layers may be deposited by cathode sputtering or by chemical methods. At very low gas pressures an auxiliary electron emitting incandescent cathode 23 is used for maintaining the discharge. With non-metallic layers 0.1 Á thick and having an initial resistance of at least 10<SP>6</SP> ohms per square, the resistance may be reduced to between 10<SP>2</SP> and 10<SP>4</SP> ohms per square.

Filed: 1952-09-03
Abstract: The invention comprises monoazo-dyestuffs of formula <FORM:0728236/IV (c)/1> in which R is the residue <FORM:0728236/IV (c)/2> where one Y is H and the other the bond connected to the azo linkage.  They may be made by diazotizing a 6-nitro-4-acylamino-2-amino-1-oxybenzene and coupling with 2,8-dioxynaphthalene-6-sulphuric acid.  Acyl residues specified are benzoyl, m- and p-nitrobenzoyl, p-chlorobenzoyl, phthaloyl, acetyl, propionyl, butyryl and Alkyl-O-CO, acetyl being preferred.  Diazotization is preferably effected with hydrochloric acid and sodium nitrite and coupling may be carried out in a neutral to alkaline, especially alkaline, medium. Coupling in the 1 or 7 position of the naphthalene is influenced by the type and quantity of alkali used.  The dyestuffs may be metallized, especially with chromium, in substance, on the fibre or in the dyebath.  Treatment in substance may be with a trivalent chromium salt, but to avoid hydrolysis of the acylamino group the use of compounds such as chromium formate or acetate is advisable.  Materials made from leather, silk, wool, superpolyamides and superpolyurethanes may be chromed on the fibre and it is stated that the unmetallized dyestuffs are used for dyeing loose wool.  In examples: (1) 6-nitro-4-acetyl-, n-butyryl-, or benzoyl-amino-2-amino-1-oxybenzene is diazotized and coupled with 2,8-dioxynaphthalene-6-sulphuric acid to give dyestuffs which dye wool in blue-green tints on after-chroming as shown in (2).
