Abstract: Contrast enhancement filter having first and second transparent glass substrates (16, 17) with first and second surfaces (18, 19; 21, 22) with the first surface (18,21) of each facing the medium in which the filter is disposed. A sheet-like circular polarizer (12) is provided formed of stretched plastic members (13) covered by layers (14) of cellulose acetate butyrate. The circular polarizer is disposed between the first and second glass substrates (16,17) and faces the second surfaces (19,21) of the glass-substrates. A dried plastisol primer layer (26, 27) is disposed on the surface of the layers of cellulose acetate butyrate facing the glass substrates. First and second layers (23, 24) of polyvinyl butyral adhesive secure the layers of cellulose acetate butyrate carried by the circular polarizer with the primer layers thereon to the second surfaces of the glass substrates. An anti-reflection coating (31) is disposed on the first surface of the first substrate.A method for manufacturing a contrast enhancement fil. ter which comprises the steps of providing a sheet-like circular polarizer (12) formed of stretched plastic members (13) and having outer layers (14) of cellulose acetate butyrate. A thin film (26, 27) of optical clear plastisol primer is applied on the outer surfaces of the cellulose acetate butyrate layers of the circular polarizer. The primer is then dried. A transparent substrate (16) is provided with first and second surfaces (18, 19). A layer (23)) of a polyvinyl butyral adhesive (23) is then applied to the second surface (19) of the first glass substrate. The circular polarizerwith its primer layerthereon is placed on the layer of polyvinyl butyral adhesive. Another layer (24) of polyvinyl butyral adhesive is then placed on the other side of the circular polarizer. A second glass substrate (17) having first and second surfaces (21,22) with the second surface (22) with the second surface (22) facing the polyvinyl butryral adhesive is placed in the sandwich. The various parts in the sandwich are then secured into a temporary unitary assembly. Air is evacuated from between the parts and the layers. Heat and pressure is applied to the assembly to cause the parts to be permanently bonded into a unitary assembly.

Abstract: The invention is concerned with a gas burner formed by the connection together of a plurality of blade members (11) each of which is formed by the folding of a blank pressed from a sheet of material. Each blade member (11) has a pair of extruded openings (24, 26) which align with one another after folding of the blank, each of the openings having a lip (30, 32), and the lips being of different dimensions, such that the lip (30) of one blade member can fit within the lip (32) of an adjacent blade member. In this way the blade members (11) are mounted together and define an integral mixing chamber for gas and air. The upper edge of each blade member (11) is formed with an outlet aperture arrangement (20, 22) and the other edges of the blade member are sealed together. To complete the burner, a cap is mounted over the outwardly extending lip of the blade member at one end, while a gas inlet pipe is mounted adjacent to the outwardly facing opening of the blade member at the other end.

Abstract: During the pre-soldering or tinning of printed circuit boards, as a rule, also the drill holes or bores and, in particular, the through-metallized drill holes are filled in an undesirable manner with solder. This solder must be removed before mounting the electrical components or elements upon the printed circuit boards. A simple apparatus is disclosed for this purpose, affording a faultless de-soldering of the drill holes, without deleteriously affecting the properties of the solder material. The printed circuit boards, in a condition where the solder applied during the pre-soldering operation is still molten, are accelerated at least once and thereafter suddenly brought to standstill in such a fashion that the excess solder is knocked or propelled out of the drill holes. The apparatus serves to guide the printed circuit board essentially horizontally in a frame and to accelerate such printed circuit board in a guided vertical drop or fall in the direction of an impact location, so that upon concussion of the frame at the impact location the excess solder is downwardly knocked or propelled out.

Abstract: The portable lifting device has two identical trestles which are arranged transversely at a distance from one another under a bedstead frame (3). Each trestle has a supporting member (4) and two guide links (5, 7) pivotably linked to this supporting member (4). The guide links are pivotably linked to a base (10) and are connected to one another by a coupling rod (12). On the articulated parallelogram consisting of the guide links (5, 7), the supporting member (4) and the base (10), a hydraulic lifting cylinder (16) with an integrated pump (19) acts on the guide link (5) of one trestle (1), as a result of which the supporting member (4) is lifted. The trestle (1) has a further lifting cylinder (30) which is connected via a line (34) containing pressure medium to an identical lifting cylinder (35) arranged on the second trestle (2). The two lifting cylinders are arranged in conformity with one another and their piston rods (31, 36) move in opposite directions so that the movement of the guide links of the first trestle (1) is hydraulically transmitted to the guide links of the second trestle (2). The lifting device consisting of individually portable trestles is readily transportable. <IMAGE>

Abstract: The processor contains a relatively small local storage (LS 12) which can be effectively expanded by utilizing a portion of a processor's store-in-cache (63). The cache allocates a line (i.e. block) for LS use by the instruction unit (IE) sending a special signal with an address for a line in a special area in main storage which is non-program addressable (i.e. not addressable by any of the architected instructions of the processor). The special signal suppresses the normal line fetch operation of the cache from main storage caused when the cache does not have a requested line. After the initial allocation of the line space in the cache to LS use, the normal cache operation is again enabled, and the LS line can be castout to the special area in main storage and be retrieved therefrom to the cache for LS use.
