Abstract: LATCH FOR A FIRE SCREEN FOLDING DOOR ASSEMBLY   Abstract of the Disclosure A latch for a fire screen folding door assembly having a projecting guide adjacent its inner edge adapted to move in a horizontal guideway in a supporting frame.  A latch element carried by the frame is movable selectively to a first position in the path of movement of the guide and to a second position out of the path of movement of the guide.  The latch element is resiliently held in its first position until the guide engages the latch element and moves the same to its second position. A recess in the latch element receives the guide upon movement of the door assembly to extended, closed position permitting the latch element to return to its first position and thereby secure the door assembly in closed position.  An actuator is connected to the latch element for moving the latch element to a position to release the guide.

Abstract: ABSTRACT OF THE DISCLOSURE A composite video signal containing an information portion and a synchronisation pulse is encoded by shifting the level of the synchronisation pulse and also by inverting the information portion.   The encoding is switched on and off at a randomly chosen frequency, under the control of a random number generator    enabled at regular intervals.  The encoded  signal is transmitted with a data signal representing the random number so that a receiver can decode the received signal.   The transmitted data can include details of undesired recipients, to disable their decoders.   Applied to a pay TV system, the transmitted data can include the rate to be charged for the program and a billing mechanism at the receiver will meter the appropriate charge.

Abstract: ABSTRACT OF THE DISCLOSURE.          Tongue and groove boards are provided with integral spacers that permit expansion of the assembled boards without buckling, by milling on the bottom of the groove a central longi-tudinally extending rib of triangular cross section.  Spaced por-tions of the rib, of total length that is most of the length of the board, are then compressed to the level of the bottom of the groove, thereby leaving a series of relatively weak projections which serve to space the boards apart the necessary distance during assembly, but which are not strong enough to resist compres-sion upon expansion of the boards under the influence of moisture or temperature.

Abstract: ABSTRACT            A method and apparatuses are disclosed for making shingles. The method consists of clampingly holding a block of material to be cut and conveying such block while it is clamped along a selected path through the clamping mechanism and causing relative movement between two cutting means which are inclined relative to one another to firstly cut a shingle from the block tapering in one direction and followed by a second shingle tapering in the opposite direction.  The apparatus includes means for receiving and clampingly holding blocks as they are fed in sequence thereto and means to feed the block while it is clamped.  The block is fed into the path of two cutting mechanisms and upon relative movment of the clamped block and the cutting mechanisms, the first cutting mechanism cuts first one shingle tapering in one direction and the second mechanism thence cuts a second shingle from the block tapering in an opposite direction, the cutting mechanisms being inclined relative to one another providing the appropriate taper for the shingles cut thereby from the block.  The block clamping and feed mechanism includes two power driven spaced apart conveyors inclined in a direction toward one another in the direction of feed, progressively applying increased clamping forces to the block as it is moved therethrough toward the cutting mechanism.  The conveyors each have a plurality of driven rollers disposed parallel to one another and are driven in synchronism, moving the block incrementally in amounts corres-ponding to the thickness of shingle desired.  The cut shingles are conveyed to an edge trimming apparatus and are moved by conveying means through at least one trimming station having cutting means for trimming the edges of the shingle.  Upstream of the cutting means there is located a scanner that provides information to a computer that processes the information and actuates movement of the trimming saws to trim the edges of the shingle minimizing the amount of waste for each shingle.  Defect cutting devices are also provided for removing defects in shingles and they too are controlled by information provided by the computer.

Abstract: ABSTRACT:                 9 In a cathode ray tube, in particular a tele-vision camera tube, a getter is assembled so as to be thermally independent of the electron gun and may be pro-vided with any desired electric potential. The getter is positioned in a tubular envelope portion of the tube by means of a supportion  member which bears on a supporting edge in the envelope. The supporting edge is formed by a substantially stepwise reduction of the internal trans-verse dimension of the envelope portion. The supporting member comprises an inner ring which is connected to an outer ring in a restricted number of places. In the cir-cumferential direction the inner ring and the outer ring show an interruption so as to counteract excessive heating of said rings during an inductive heating of the getter. Metal strips which support the getter are connected to the inner ring.  The supporting construction is excellently suitable for use in comparatively small cathode ray tubes.

Abstract: Abstract of the Disclosure.      Disclosed is a method in which a starting material is rolled and made into a pipe by passing the material through a two-roll Mannesmann piercing mill, a three-roll mandrel elongator, a multiple-stand continuous pipe rolling mill of the mandred bar restraining type and a high-reduction sizer in this order.      The sizer is arranged in succession to the exit side of the multiple-stand continuous seamless steel pipe rolling mill of the mandrel bar restraining type so that the shell being rolled by the rolling mill is gripped by the sizer which in turn withdraws the shell being rolled from the mandrel bar of the rolling mill in such a manner that a tensile stress acts on the shell extending between the rolling mill exit and the sizer entry while effecting the rolling of the shell-by the rolling mill and the rolling of the shell by the sizer simultaneously.      The amounts of work shared by the piercing mill, the elongator, the rolling mill and the sizer are suitably determined in such a manner that the merits of these mills are rationally made available and combined thereby cooperative-ly ensuring high efficiency and a high degree of processing accuracy.
