Title: Method for coating a solid electrolyte present in the form of a sheet
Inventor: MUELLER KLAUS DR
IPC: C25B9/23
Filed: 1981-05-27
Abstract: A solid electrolyte in the form of a sheet is coated with an electrode material by stirring the latter, in powdered form, into a viscose polymer solution, which acts as the carrier and contains a polar solvent, and applying the paste thus obtained directly to the solid electrolyte or to a substrate having a non-adhesive surface and driving off this solvent by drying at elevated temperature. If the paste has been applied to a substrate having a non-adhesive surface, the coating is peeled off as a whole, is placed onto the solid electrolyte and permanently bonded by a heat treatment. The polymer used can be a material which is related to the solid electrolyte to be coated or can be identical therewith. The porosity of the coating can be varied by adding pore formers in the form of aqueous salt solutions.

Patent CH-650545-A5 (CH)
Title: Insulating building block and masonry structure produced therefrom
Inventor: SCHNYDER HANS
IPC: E04C1/41
Filed: 1981-06-30
Abstract: The insulating building block has a cuboidal load-bearing structure with vertical cavities (13) which are formed between vertical slabs (10, 11) and offset webs (12) connecting said slabs in one piece. The inner slabs (11) do not reach to the end surfaces (3) of the load-bearing structure and the webs (12) do not reach up to the upper surface (5) of the load-bearing structure (1). As a result, the foam blocks (20), which are accommodated in the vertical cavities (13) and reach to the lower load-bearing-structure surfaces (6) and, in the end region, to the load-bearing-structure end surfaces (3), butt against one another in a mortar-free manner, despite the introduction of mortar between the inner slabs (11), and avoid mortar cold bridges at the end surfaces (3) of the load-bearing structure. Above the webs (12), foam blocks (21) are arranged, continuously from end surface (3) to end surface (3) of the load-bearing surface, between the slabs (10/11 and 11/11) such that they project beyond the upper surface (5) of the load-bearing structure. As a result, load-bearing mortar can be applied between these foam blocks (21), on all slabs (10, 11), without a cold bridge thus arising. <IMAGE

Filed: 1978-06-26
Abstract: This circuit arrangement exhibits a zero crossing detector (16), a threshold logic (21..25), a delay circuit (30) and a logic circuit (32). The zero crossing detector (16) continuously detects the zero crossings (B) of the incoming voice-frequency signals (A). With the intended frequencies, the frequency detection circuit (15) operates and activates the threshold logic (21..25) and the delay circuit (30). The latter in each case delays pulses (G) derived from the zero crossings by the duration of a quarter period of the frequency of the voice-frequency signals (A). If a delayed pulse (G) coincides in the logic circuit (32) with a signal (F) of the threshold logic (21..25) which indicates an inadmissible level fluctuation, a stop and restart signal (H) is output at the output (33). <IMAGE>

Patent CH-611226-A5 (CH)
Title: Device for supplying a liquid to a container from a receptacle closed by a septum
Inventor: SMITH DAVID S
IPC: G01N33/48
Filed: 1976-01-07
Abstract: At one end of a container (30) there is fixed a piston (472) which slides in a cylinder (468). An axial passage (476) of the piston connects the container (30) with the cylinder (468) via a valve (488) preventing the liquid from leaving the container. The top of the cylinder has an axial passage (455) in which is fixed the tip of a hollow needle (444). The needle is forced through the septum (432) of the receptacle (422) while the piston is at the top of the cylinder. On pulling the container (30) downwards, the piston is made to slide, which causes liquid to be sucked in from the receptacle. Then, the liquid is forced into the container (30) by pushing the piston back to the top of the cylinder. It is thus possible to transfer blood serum from a rigid receptacle to a closed container, while avoiding contamination of the serum. <IMAGE>

Title: Heavy liquid - prepn and adjustment for sugar industry
IPC: C13B25/00
Filed: 1971-02-01
Granted: 1971-11-05
Abstract: Heavy liquid, for use in the sugar industry is prepd. and adjusted for density, in a process in which the byproduct scum from sugar. mfr. is used as the heavy medium. The scum consists of 50% of dry material which is chiefly CaCO3; it also contains the impurities of the beet juice in the form of Ca salts. By diluting this scum with water, suspensions with densities ranging from 1.15 to 1.30 can be prepd. The scum arriving from the refinery can either be evacuated to waste or sent to the heavy liquid container via a valve controlled by a density control device. This valve opens when the density of the liquid in the sepn. appts. falls below 1.15 and close agains when it rises above 1.25. The process is of advantage when, in dry weather, the beets are too clean and do not carry sufficient earth or clay for giving a suspension of the desired density.
