Abstract: SAFETY DEVICE FOR LADDER CLIMBERS                    ABSTRACT OF THE DISCLOSURE           A safety clamp slidably mounted on a vertical safety carrier, such as a cable or rod, in proximity to a ladder is attached to a workman's belt by a pivotal actuating arm which shifts a wedge plate into clamping engagement with the safety carrier immediately under free-fall conditions encountered if the workman falls from the ladder.  Instantaneous actuation of the wedge plate into clamping engagement with the safety carrier in response to the slightest pivotal movement of the actuating arm towards its closing position is provided by cam action exerted against the wedge plate by the actuating arm and by a cam member on the clamping bracket.  Cam follower and guide sur-faces on the upper end of the wedge plate cooperate with camming action of the actuating arm against the lower end of the wedge plate to maintain the wedge plate in an upright position of uni-form contact with the safety carrier.

Abstract: Abstract of the Disclosure A method is provided for controlling the amount of active substance applied to the surface of a continuously-moving paper web, with the active sub-stance being dissolved in or dispersed in a treating liquid.  The paper web is passed over a coating unit and includes an opening through which the treating liquid is applied to the paper web.  The method includes the steps of supplying a first fluid with a predetermined amount of active substance to a first batch-ing device and supplying a second fluid consisting of pure solvent or dispers-ing agent to a second batching device.  The output of the first batching de-vice is controlled in response to the speed of the paper web to control the amount of active substance supplied to a mixer, and the output of the second batching device is controlled in response to the fluid pressure at the opening of the coating unit to control the amount of solvent or dispersing agent sup-plied to the mixer.  Then, the outputs of the first and second batching devices are mixed to form the treating liquid, which is then supplied to the opening of the coating unit so that the paper web is completely covered with treating liquid even in sections of the paper web where the surface roughness is rela-tively high, as compared to the remainder of the paper web.

Abstract: ABSTRACT:           A resynchronization arrangement for a data receiver having an auto-adaptive equalizer and a demodu-lator which utilizes a local carrier phaselocked on the received carrier by means of a control loop comprising an integrating circuit.  Starting from a signal indicating a synchronization loss the arrangement generates three command pulses: a first pulse makes the adjustable co-efficient of the equalizer and the signal in the memory of the integrating circuit equal to zero; a second pulse is used for making a reduced number of coefficients of the equalizer operative immediately after the first pulse and for reducing the time constant of the integrating circuit; a third pulse is used to make the synchronization loss indication signal equal to zero a given period of time after the end of the second pulse.  Resynchronization is obtained without the necessity of a return connection to the transmitter.

Abstract: Abstract of the Disclosure An improved process for providing corrosion protection to ferrous metal substrates is disclosed.  The improved process involves a first treating of the surface of the ferrous metal substrate with nitric acid followed by directly applying to the previously treated surface a zinc-rich coating composition.  Upon curing the zinc-rich coating composition, an adherent electroconductive coating is formed. The coating provides excellent corrosion protection and since it is electroconductive, the coating is weldable and can accept a subsequent electrocoat.

Abstract: A B S T R A C T         A hydrometallurgical process for the electrolytic recovery of selected base metals (especially copper or possibly nickel) from sulphide ore concentrates concurrently with the extraction of metallic iron in a commercially usable form.  The process involves dissolution and leaching of ore in acidified chloride anode solution from the electro-lytic cells of a primary and secondary bank of electrolytic cells to obtain iron chloride and base metal chlorides and to reduce ferric and cupric ions (say) to their lowest valence state (e.g. ferrous, cuprous).  The leaching sol-ution is transported to and distributed equally among the cathode compartments of each bank of cells to set up a solution flow from each cathode to adjacent anode compart-ments.  Elemental sulphur and insoluble residue resulting from the ore dissolution are extracted as is electrically reduced metallic copper.  The copper is obtained from the cathode compartments of both primary and secondary banks of cells.  Hydrogen gas evolved at the cathode compartment is used to reduce hydrated ferrous chloride, obtained from the cathode compartments of the secondary bank of electrolytic cells to metallic iron.  The process operates continuously.

Abstract: ABSTRACT OF THE DISCLOSURE       An article and its method of manufacture is disclosed wherein at least three sheets or thermo-plastic web material are bonded to form a laminated unit.  Energy director element sets are disposed between adjacent sheets in an orientation such that the director elements or one set are angularly oriented with respect to those of the next adjacent set to define points at which the elements of one set cross the elements or the adjacent set.  When a compressive force and high frequency vibratory energy are applied to the unit, the pressure and vibratory energy are concentrated at the defined points so that the thermo-plastic material in the region or the concentrated pressure is first to soften.  Subsequent application of compressive force and vibratory energy softens the thermoplastic material adjacent the defined points. By initially concentrating the pressure and vibratory energy, the bonding time is substantially reduced and an even flow of material is assured.

Abstract: ABSTRACT OF THE DISCLOSURE           An interface for use in serial digital data systems incorporates photo-coupling devices.  The interface comprises three photo-couplers in the input and output circuits of a data station.  Light emitting elements of two photo-couplers are connected in series with the driven element of a third coupler across a reference power supply.  The driven element of the third coupler is connected to the output of one data station and also is shunted by the output from a preceding station.  Either output causes a current flow to produce light outputs from the two light emitting elements.  The light, in turn, operates the driven elements of the other two couplers.          The driven element of one of the two couplers supplies data to the one data station, the driven element of the other coupler retransmits data to the next station.  The interface is adaptable for use in a closed loop data system by adding a fourth photo-coupler.
