Title: Cooling drink such as whisky without diluting it - involves using sealed plastics container filled with ice
IPC: F25D3/08
Filed: 1989-05-24
Abstract: The method is for cooling a drink, such as whisky, without adding ice directly to the whisky, so that the drink is not diluted with the water formed from the thawing of the ice.

Patent DE-4030790-A1 (DE)
Inventor: MAENO HIDESHI
IPC: G06F11/22
Filed: 1990-09-28
Abstract: A scan path composed of a plurality of scan registers comprises a first test mode for testing a RAM, a second test mode for testing a logic circuit and a normal mode. In the first test mode, expected value data is set in each of latch circuits of the scan register. The expected value data held by the latch circuits are determined whether their logics coincide with data read from the RAM in a determination circuit. As a result of this determination, when a fault is occurring in the RAM, the logic of the data held by the latch circuit is inverted. In the second test mode, test data is set in each of latch circuits of the scan register, and the test data set are supplied to the logic circuit. In the normal mode, data read from the RAM is supplied to the logic circuit through the selector circuit without passing through the shift register. Accordingly, the delay time of data propagation path in the normal mode is extremely small and it does not degrade the speed performance of the semiconductor integrated circuit devices.

Title: Hydrothermally-hardenable structural elements treated with compressed air and steam - to give improved stability, higher strength and/or thermal insulation properties
IPC: C04B40/02
Filed: 1991-03-25
Abstract: Mfr. of light wt. structure elements from masses which can be hardened hydrothermally. The process comprises the prodn. of a matrix which can be subjected to plastic forming, from 1. a fine-grained silicate material such as quartz sand or powdered glass; binders which can be hardened hydrothermally; 3. lightweight aggregate; 4. water; and 5. possibly hydraulic binders. The matrix is pressed to shape, followed by hardening of the shaped body by treatment with steam under pressure. The body is acted upon by compressed air before the steam treatment stage. Pref. the compressed air treatment is carried out for 5-60 second, using compressed air at a pressure of 0.5 to 5.0 bar. Steam treatment follows directly after compressed air treatment, without the compressed air pressure being turned off. The compressed air treatment acts to carry the existing moisture content into the matrix and to the aggregate grains. The air-steam mixt. used is drier than steam alone and shows less tendency to condense. This stabilises the shaped body. Moreover, hardening of the binder takes place before the water boils off. The process only represents a small modification to conventional processes, with a minimal effect on operating costs. USE/ADVANTAGE - For the mfr. of lightweight structural elements such as door arches, wall slabs or other finished parts from materials which can be hardened hydrothermally. No alternations in shape occur before or during the treatment with steam, and parts of high strength of with good thermal insulating properties can be mfd.
