Abstract: ABSTRACT OF THE DISCLOSURE         A key kit for opening tumbler locks has a key member with a shaft insertable into a tumbler lock, the shaft having a series of longitudinally-spaced recesses into which the tumblers in the lock can respectively enter. A foil of impressionable material is removably position-able on the shaft over the recesses, and a tumbler dis-placing member is insertable into the lock with the shaft and foil to displace the tumblers without the tumblers engaging the foil.  The tumbler displacing member being removable from the lock after the shaft and foil have been inserted therein to enable the key member to be manipulated to cause the tumblers to make impressions in the foil corresponding to the key shape required to open the lock.

Abstract: Abstract of the Disclosure An improved glow discharge deposition appara-tus for depositing amorphous layers upon at least one substrate, the apparatus including a housing capable of withstanding vacuum pressures, a sub-strate upon which the amorphous layers are depos-ited, an r.f. powered cathode adapted to cooperate with the substrate for producing a plasma region in the housing, layer-producing materials adapted to be introduced into the plasma region, and heat-ing elements for warming the substrate to a deposition-effecting temperature.  The improvement is provided by an electrically insulated base adapted to support the cathode in a non-horizontal, preferably a vertical, plane and a prop adapted to support the substrate in a plane adjacent and parallel to the non-horizontal plane in which the cathode is supported.  The non-horizontal cathode is adapted for use either in a single deposition chamber for depositing a single amorphous layer onto the substrate or in a machine having a plurality of successive deposition cham-bers for depositing successive amorphous layers onto the substrate.  In either embodiment, oppo-site planar faces of the cathode may be employed in combination with a pair of substrates, deposed in planes parallel to the plane of the cathode faces, to develop two plasma regions for simulta-neously depositing amorphous layer-producing mate-rial on each of the substrates.  The substrate can be formed either of discrete plates or of a con-tinuous web of material.  In the embodiment wherein the substrate is formed of discrete plates, a rotatable arm, associated with each deposition chamber, is adapted to cyclically introduce the substrate into the deposition cham-ber and expel the substrate from the deposition chamber.

Abstract: ABSTRACT This invention provides an automatic focussing apparatus for use in a television camera, having an image pick-up device, a lens and an associated focus setting device.  A focus modulating means cyclically modulates a focus setting on an imaging receiving surface of the image pick-up device and a first drive means drives the focus modulating means in response to a signal of a given frequency which is 1/n as large as a frequency of a vertical synchronization signal of a standard television signal, where n is an integer larger than 2.  A plurality of band-pass filters having different center frequencies and different reference levels from one another filter a video signal derived from the image pick-up device and a detecting means detects a component of said given frequency from an output of one of the band-pass filters by means of an envelope detection method.  A synchronous detecting means obtains a focus control signal including a polarity and an amplitude, by means of a synchronous detection method utilizing said given frequency component and said given frequency and a second driving means controls the focus setting device of the lens in response to the focus control signal.  A selecting means determines the focus control signal to be an output signal of one of the band-pass filters which has the highest center frequency among those of the band-pass filters having a larger output than their associated reference level.  Since the lens is included in the feedback loop, the accuracy and the stability of the lens itself does not matter.  Furthermore, the lens can be made of plastic light weight material.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is provided for continuously precipi-tating precipitate-forming ions under elevated temperature and pressure from a solution thereof using recycle precipi-tate seed as a precipitation aid.  The process comprises establishing a solution of the precipitation-forming ions, feeding the solution at an elevated temperature and pressure through an autoclave having a series of precipi-tation compartments, and adding a precipitation agent to the solution while it is maintained under elevated tempera-ture and pressure to precipitate the precipitation-forming ions and thus form a precipitate slurry.  The slurry is caused to flow out of the autoclave by virtue of the prevailing pressure in the system to a solids-liquid separator which is serially connected in pressure communi-cation with the autoclave, the separator having a dense slurry fluidized leg or an elutriation column and being disposed at an elevation relative to the autoclave to pro-vide a hydrostatic head of the withdrawn slurry in gravity-flow relationship to the autoclave.  The precipitate may be continuously elutriated in the column under the pre-vailing pressure so as to provide an upper slurry portion of precipitate fines and a lower portion of product con-centrate.  The precipitate fines are then caused to flow by gravity as seed material to the autoclave without requiring the use of pumps for circulating the slurry.

Abstract: ABSTRACT       In a method for copying retouch in color picture reproduction, color values are initially acquired by image-point-by-image-point trichromatic color picture scanning and digitization.  The color values are deposited in a storage medium and are addressable by image point coordi-nates.  With the coordinate pen of a coordinate acquisition means, the retoucher first marks a read point within a first image region from which a pattern is to be taken and a write point within a second image region into whith the pattern is to be copied with image point precision.  A distance between the read and write points is determined from the acquired image point coordinates and is fixed.          The retoucher then acquires all image point coordinates within the first image region with the assistance of a coordinate pen.  The image point coordinates of those image points within the second image region exhibiting the respective fixed distance from the acquired image points are simultaneously identified and a double coordinate pen is thus simulated.  For precise pattern transfer, the color values of the first image region addressed with the assist-ance of the double coordinate pen are replaced image-point-by-image-point by the simultaneously addressed color values of the second image region or by values calculated from the color values.

In its interior, freely burning plasma torches are produced between plasma burners guided through the lid or through the side walls of the furnace body and a bottom electrode. Fluxes and reactive substances to be melted and reacted, respective-ly, are charged into the region of the plasma torches. In order to increase the energy supply to the charges to be melted or reacted and thus improving the thermal ef-ficiency or kinetics  of the process, additional gas flows, which differ from the original plasma gas, are injected into the plasma torches. An arrangement for carrying out the method includes a furnace through whose lid or side walls plasma burners are guided and in whose bottom a counter electrode is arranged. Supply means for introducing additional gas flows into the region of the plasma torches are additionally provided.

Abstract: Abstract The invention is a high frequency hetrodyne receiver front end for receiving a communications signal comprising a desired information frequency and an undesired image frequency.  The receiver comprises a bandpass filter, a preamplifier responsive to the bandpass filter, a mixer and a coupler means between the preamplifier and the bandpass filter.  The coupler means defines a reactive short at the undesired image frequency due to impedance characteristics of the coupler means. The coupler means thereby eliminates the image frequency noise at the input of the preamplifier.  Preferrably the coupler means is a transmission line of a length L where L equals n.pi./.beta. and n is an integer and .beta. is proportional to the wavelength of the image frequency.
