Title: Impregnating tissue samples with paraffin for histological examination - by treating with isopropyl alcohol and impregnating in molten paraffin bath under vacuum with application of ultrasound
Inventor: BERGER HERMANN JULIUS DR
IPC: B01J19/10
Filed: 1990-06-15
Abstract: A process for impregnating tissue samples with paraffin  comprises (a) fixing the tissue sample with a fixing agent, (b) dewatering the tissue sample using isopropyl alcohol and (c) impregnating the tissue sample in a sealed treatment chamber at an operating temp. which is below the b.pt. of isopropyl alcohol at atmos. pressure but at which the paraffin is liq., by immersing the tissue sample in the liq. paraffin and applying ultrasound to the tissue sample and to the surrounding liq. paraffin whilst maintaining a vacuum in the treatment chamber which is chosen such that at the prevailing operating pressure the b.pt. of isopropyl alcohol is equal to or (pref.) below the operating temp. USE/ADVANTAGE - The process avoids the necessity for long impregnation times and is thus quicker to carry out than previous processes, gives complete removal of isopropyl alcohol from the sample and optimum impregnation with paraffin, and avoids contamination of the paraffin bath with isopropyl alcohol, thus giving reduced consumption of paraffin. The impregnated tissue samples can be embedded in paraffin blocks from which very thin slices can be taken for microscopic histological examination.  The process can be used with human, animal and plant tissue samples and is a useful diagnostic aid.

Patent DE-4114609-A1 (DE)
Inventor: CAPELLE GERD
IPC: B29C48/67
Filed: 1991-05-04
Abstract: A pin-lined transfer extruder is presented, in which the pin-lined barrel and transfer mixing sections, known per se and until now only used individually, are used together in one extruder. Restricting pins arranged in the transfer mixing section in the region of the greatest barrel channel volume permit universal use of the extruder with respect to the extrudate. The combination of both mixing systems surprisingly allows an increase in the material throughput of 60% to 100% while maintaining the same mixing quality and halving the drive torque. Due to a constant number of barrel and screw channels, the number of barrel and screw flights remains independent of the channel cross-sectional area of barrel and screw. <IMAGE>

Patent DE-4134996-A1 (DE)
Inventor: KANNENGIESSER WERNER DIPL ING
IPC: C06C5/04
Filed: 1991-10-23
Abstract: The detonating cord is used, for example, in oil exploration at great depths, where it must withstand high temperatures and pressures. The sheathing (11) is produced from a shrinkable hose (12) which is thermally shrunk onto the raw cord (10) containing explosive. The hose (12) consists preferably of radiation-crosslinked polyethylene. The use of a shrink hose does away with the long preparation and curing times of plastic sheathing. The process temperatures required for shrinking are acceptable with regard to safety from ignition of the explosive. The process allows in particular detonating cords for high pressures and high ambient temperatures to be produced without any problems. <IMAGE>

Patent DE-4140831-A1 (DE)
Inventor: WAGNER ROLAND
IPC: G01N27/42
Filed: 1991-12-11
Abstract: Equipment that works according to a thermoanalytical process is distinguished from known, wet measurement methods particularly in that it requires no complex calculations and no toxic chemicals which then create the problem of their disposal. The equipment essentially consists of an analytical path with four base components; molecular sieve (1), temperature cell (2), pyrolysis unit (3) and water cell (4), as well as an electronic section that evaluates the electric signals measured and appropriately represents them on a monitor. A moisture sensor is also disclosed having a response probability considerably improved with respect to comparable conventional moisture sensors. The measurement accuracy is also increased, as the dwelling time of the gas to be analysed is extremely long since the cross-section of two mutually linked, U-shaped glass capillaries (10, 11) exposed to the gas is very small. In principle, the structure of this moisture sensor consists of at least two coils (4) wound on a quartz glass pin (3), and two mutually electrically insulted electrodes on which a strongly hygroscopic substance (P2O5) is applied, the conductivity of which varies considerably with the humidity content.

The switching transistors are controlled by the controller to assume condition of lower or higher impedance of the collector-emitter paths. Two X-Y lines are provided for each data or telephone connection. To make a data or telephone connection, both transistors for the two X-Y lines are controlled by the single common controller. The controllers (T1, T2, T3) are made up of a single transistor. The switches (S1-S6) include transistor elements with low current requirement and low DC resistance. USE/ADVANTAGE - Esp. for small telephone networks. Efficient switching considering symmetry and damping defaults. Only requires small control and switching power but provides accurate on and off switching.
