Patent AT-A163295-A (AT)
Inventor: BLEIER HARALD
IPC: B29C45/17
Filed: 1995-10-03
Abstract: A closure unit for a machine handling injection moulding material, esp. a plastic injection moulding machine, has a force transmitting frame (1) consisting of a lower connecting base (2) with a side member (3, 4) on each side. One side member (4) carries a tool support plate (5) while the other (3) has a header plate (9) with a sliding tool support plate (6). Actuators (10, 11) between the header plate (9) and the tool support plate (6) provide a force for opening and closing the tool (7, 8). At least two actuators (10, 11) are arranged at different heights relative to the base plate (2) so that slight deflections of the force transmitting frame (1) are compensated by differential movements (x1,x2) of the actuators (10, 11) in order to obtain a constant closing force distribution over the contact plane of the tool halves (7, 8). Pref. hydraulic cylinders (10, 10', 11, 11') are arranged at the four corners of the tool support plate (6). The tool support plate (6) runs along a guide plate (12) which is attached to the other tool support plate (5) so that the guide plate (12) does not deflect with the frame (1) under the closing forces. All the hydraulic cylinders are fed from a common supply under the same pressure and the compensating movements (x1,x2) take place automatically. Alternatively separately controlled hydraulic pressures can be applied to the upper (10) and lower (11) cylinders to deal with tools with asymmetric mould cavities.

Title: Appts. for feeding liq. for clarification to static filter - with inclined grill, using divergent flow channels in series to eliminate blockages and cleaning problems
IPC: B01D35/28
Filed: 1982-04-06
Abstract: Appts. delivers a liq. contg. suspended impurities for removal to the top of a static gravity filter of the inclined grill type. The incoming liq. flows in succession through at least two laterally divergent, flat spreader channels. The width of the inlet of each channel is at least equal to the width of the outlet of the upstream channel or supply pipe. The least dimension of any cross-section of a channel is adequate to give clearance to the biggest suspended impurity or agglomeration of impurities. The channels are sized and cross section are profiled so that impurities remain suspended as the flowing liq. becomes progressively shallower. Pref. a first channel rises vertically to feed a second spreader channel which is open-topped and practically horizontal. The second channel rises very slightly to bend gently downwards and discharge via a guide chute on to the top edge of the inclined filter grill. Used partic. in sugar refineries, for the filtration of can or beet sugar liquors. The controlled flow of liq. on its way to the filter eliminates dead spaces and prevents build up in the feed channels. There is no need for cleaning stoppages.

Abstract: LOGIC NETWORK TEST SYSTEM WITH SIMULATOR ORIENTED FAULT TEST GENERATOR                 Abstract of the Disclosure Disclosed is a technique for testing highly complex, functional logic where long sequences of test patterns are needed.  A logic network to be tested comprises a large number of logic blocks.  The inputs to several of these logic blocks are also the primary inputs (PI) to the logic network to be tested while the output of several of the logic blocks are also primary outputs (PO) of the logic network to be tested.  However, the inputs and outputs of many logic blocks of the network to be tested are inaccessible since as is well known in large scale integration (LSI), a large number of internal circuit nodes cannot be probed directly.  In accor-dance with the present disclosure, such a logic network to be tested is simulated and each of the logic blocks as well as the inputs and outputs of each of these logic blocks is uniquely defined.  A first test pattern is then applied to the primary inputs (PI) of the network to set the logic levels on these primary inputs to known values.  A particular one of the logic blocks within the network is then selected and a specific fault associated with the particular logic block is assumed.          A test value for this assumed specific fault in the simulated network is then propagated towards a primary output, one logic stage at a time, by backtracing through the network to a primary input to determine which primary input value must be altered in order to propagate the assumed fault towards a primary output.  Without developing an entire test sequence, analysis at each step determines whether the test is in fact progressing by propagating the test value through the network toward the primary output.  The term "test value" is defined as the binary value of a point within the logic network that is opposite from that expected in the absence of the assumed fault.  When a "test value" has been successfully propagated to a primary output (PO), then it is known that the particular sequence of input test patterns is suitable for detecting the specific fault assumed in the simulator. By applying the same sequence of test patterns to the actual network under test and comparing the primary outputs of the network under test to the primary outputs of the simulated network, it is determined whether the particular assumed simulated fault is actually present in the network under test.  On a real time basis, each time a successive pattern is applied to the simulated network, it is analyzed, and if found unsuitable, it is discarded and a different changed input pattern is sought by backtracing to a primary input through a different path.  Each successive pattern is applied to the network under test only if found to be valid.

Abstract: ABSTRACT OF THE DISCLOSURE           A relief mechanism for a jaw crusher which includes a hydraulic fluid filled piston-cylinder arrangement mounted on the frame and connected to the rear toggle of the jaw crusher.  The hydraulic fluid is connected to a pressure sensor and a relief valve.  The hydraulic fluid is maintained at a predetermined pressure during normal crushing operations.  Upon encountering a material which cannot be crushed, the rear toggle transmits the higher than set pressure to the piston-cylinder arrangement thereby increasing the fluid pressure in the piston-cylinder arrangement.  A pressure sensor senses this increased pressure and opens the relief valve to dump the entire hydraulic system.  As the hydraulic system is dumped, the piston moves into the cylinder.  The relief valve is sized so that the fluid is exhausted from the cylinder at a rate which allows unrestrained movement of the piston during relief.          A positive stop on the piston-cylinder arrangement insures pressurizing of the system.  An interlock with the crusher motor may be provided to shut down the crusher when tramp is encountered.

Abstract: METHOD OF CLEANING GLASS WINDOWS AND MIRRORS          Abstract of the Disclosure Glass surfaces having undesirable foreign substances thereon are cleaned with an aqueous cleaning composition containing water and a catalytically effective amount of a novel catalyst.  The invention is especially effective in cleaning glass windows and mirrors, and glass surfaces in general where it is important that the cleaned glass not have a film or residue thereon.  In practicing the method, the aqueous cleaning composition containing water and the catalyst is applied to the glass surface and intimately contacted therewith until the foreign substances may be removed by a wiping action.  Thereafter, the glass surface is wiped to remove the foreign substances and any excess aqueous cleaning composition without leaving a film or residue on the clean glass surface.          When desirable, the aqueous cleaning composition may also contain a surface active agent or a combination of a  surface active agent and a water softening agent.          The novel catalyst which is used in preparing the aqueous cleaning composition is prepared by steps including admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of dissolved water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous finely divided or colloidal suspension of the reaction product, admixing a micelle-forming surfactant with the aqueous medium, and agitating the aqueous medium containing the finely divided or colloidal particles and surfactant to form catalyst containing micelles.
