Patent DE-2539771-A1 (DE)
Title: Polarographic Clark-type detector - having porous polypropylene membrane and esp. for transcutane measurement of gas concn. in blood
Inventor: MUEHL GERHARD
IPC: G01N27/49
Filed: 1975-09-06
Abstract: Detector for determining the partial pressure of gases, esp. of oxygen in liquids, comprises a separating membrane, which is impermeable to the electrolyte but permeable to the appropriate gases. The membrane surrounds the measuring system and isolates it from the medium. A layer, on the inner face of the membrane, stabilises the thickness of the electrolyte layer. The stabilising layer is of a micro-porous polypropylene sheet, pref. having a thickness of 10-50 mu. The microporous polypropylene sheet is pref. bonded to a non-porous sheet of the same type, which itself constitutes the membrane, to form a composite sheet. By comparison with stabilising sheets of 'Cellophane' (RTM) and 'Cuprophane' (RTM), the microporous polypropylene sheet does not expand and become soft when satd with the electrolyte. By comparison with the other conventional soln. of a grating or lattice fabric, the thickness is greatly reduced, therefore giving a much more rapid response.

Title: Support moulded brick for walking beam furnace - has parallel steps for reversing brick, after wear of one face
IPC: F27D3/02
Filed: 1975-09-25
Abstract: In the furnace used for heat treatment e.g. of billets or ingots, the fixed and walking beams have on their surfaces replaceable, moulded wear resistant bricks held on the beam structure. Each moulded brick has upper and lower faces for supporting heat treated material. One of these faces is in contact with this material while the other face rests on a support. Each brick is rotated after the first face is worn. These bricks have two equal sections connected by a sloping step. On turning the bricks over it is only necessary to loosen the adhesive bonding between the brick lower face and support. These bricks are relatively simple and economical to produce.
Patent DE-2556743-A1 (DE)
Title: Device for reeling plastics sheet continuously onto revolving core - with pressing roll pressed radially onto reel to produce smooth sheet
Inventor: KORNELI WOLFGANG DR
IPC: B29C53/32
Filed: 1975-12-17
Abstract: A continuous reeling device for plastics sheet comprises a cylindrical core on which the reel is formed, a pressing roll applying pressing onto the sheet as it runs onto the reel, and a width-stretching roll on the approach side to the pressing roll and reel. The width-stretching roll and pressing roll have their axes parallel, horizontal and fixed one relative to the other, rotatably mounted in common bearing elements at their ends. This combined assembly is mounted on a frame so that they can pivot about the centre of their axes in the horizontal plane and can displace radially towards and away from the reeling core. The core is horizontally mounted in a separate frame. A constant relative position of the pressing roll and reel, independent of the diameter of the reel, is maintained at all times. Thus variations in the diameter of the reel have no effect upon the flatness of the sheet and tightness of the reel. Moreover, since the width-stretching roll and pressing roll can pivot horizontally, the pressure is equally well applied even if the reel is of larger diameter at one end than at the other, due to uneven thickness of the sheet. This feature is maintained by the use of two pneumatic cylinders, one acting upon each end bearing element.

Patent DE-2708983-A1 (DE)
Inventor: BRINKMAN BARRIE LESLIE
IPC: H04M/
Filed: 1977-03-02
Abstract: In order to simplify the charging and accounting procedures in a telephone network and, at the same time, to carry these out in a more reliable manner, the system exhibits a multiplicity of switching devices (11, 12, 18; 21, 22, 28; 31, 32, 38) with keyboards and display devices. These are connected group by group to control devices (10, 20, 30) for the user which respond to commands keyed in in order to obtain data from peripheral storage devices and to record details of the telephone connections on magnetic tape. Each control and peripheral device exhibits microprocessors for controlling the individual functions and carrying out tests which determine the operating states of the devices and generate relevant display signals. All these devices are connected to a monitor (6) for recording these display signals. Each device can exhibit a monitoring clock generator with a counter. The latter is regularly incremented and periodically set to zero, responding to a software command. Thus, when a central processing device enters a software loop, the counter exceeds a threshold value and generates a signal indicating the presence of such a loop. The same timing generator can also reset the central processing device into a starting position and delete all data recorded as consequence of a program execution up to this time. Finally, there can be a diagnostics device so that a technician can carry out routine checks of the individual devices. <IMAGE>
