Patent DE-2712572-A1 (DE)
Inventor: KINUGAWA KIYOSHIGE
IPC: G02F1/139
Filed: 1977-03-22
Abstract: In order in a liquid-crystal display device having a helical structure of the liquid crystal to achieve as steep as possible a rise in the contrast with the voltage while at the same time avoiding induced domains, the electrode sides (3, 4) of the substrates (1, 2) of the display device are provided in each case with a boundary layer (10) by means of shadow casting. The casting directions are selected such that their components in the boundary layer planes enclose together with the viewing direction (S), given by the display content, of the device an angle of 90 DEG  to 180 DEG  for the upper and 0 DEG  to 90 DEG for the lower substrate, measured in the sense of the helix of the liquid-crystal helical structure from the upper to the lower substrate. <IMAGE>

Title: Heart pacemaker pulse shaping circuit - incorporates monostable and astable multivibrators in trigger stages for safe operation
Inventor: BLASER REINHARD DR ING
IPC: A61N1/372
Filed: 1977-03-19
Abstract: The battery operated heart pacemaker has a control circuit with two branches forming two different paths to obtain pulses of determined shape and/or recurrence frequency to give a safe signal of favourable time length and amplitude. the electrode is connected by a preamplifier to a trigger stage and a monostable multivibrator. This is followed by a second trigger stage and then an astable multivibrator. At the input of the astable multivibrator is a capacitor which blocks successive pulses. The multivibrator arrangement is triggered by an input signal so as to actuate the output pulses independently of the input. Also, the repetition of the pulses is related to the last triggered input signal.

Title: Large grained gravel wall rendering fixture - includes plastics or metal holder with protruding extension and dual component adhesive
Inventor: BROETHER JUERGEN
IPC: E04F13/14
Filed: 1977-05-09
Abstract: The process is used for applying a rendering of large-grain gravel with grain size of 50-350mm, usually involving great difficulty in attaining a firm hold on vertical walling. This involves a partially formed-on retainer made of plastics or metal, with an extension protruding into the masonry. The open end of the retainer is locked with a gravel stone by a dual-component adhesive. The extension may be a single piece with the retainer, and can be of metal with a plastics retainer formed onto it; or they may be two separate units, joined together after adhesion of the retaining part to the gravel. This enables every individual gravel stone to be accurately fixed in place.

Patent DE-2806039-A1 (DE)
Inventor: KMETZ ALLAN R DR
IPC: G01R13/00
Filed: 1978-02-14
Abstract: A matrix drive device is described in which the signal to be displayed appears as a trace of non-excited matrix elements. In contrast to known devices of this type, it is not necessary with increasing row number N to increase the voltage applied to the rows and column electrodes. Rather, a signal voltage independent of the display signal to be represented is applied to each of the N row electrodes, Z nu , these signal voltages forming an orthogonal function system having the same r.m.s. value in each case. One of the row signal voltages is likewise applied in each case to each of the column electrodes S mu , the allocation of these signal voltages to the respective column electrode, S mu , being controlled by the display signal to be represented. It is preferable to make use as signal voltages of those which have a Walsh function characteristic. <IMAGE>

Title: Sewage aerator plant - combines surface aeration with ejector aeration system for better efficiency
Inventor: WENK KARL-HEINRICH
IPC: B01F25/60
Filed: 1978-04-08
Abstract: A system for the aeration of liquids, esp. for the biological sewage treatment, combines two aeration principles. The naturally aerated surface water is continuously directed through slots in a tube to a revolving spray disc which atomises it. After this surface aeration, a pump passes the liq. to ejectors which mix it with air and discharge the mixt. in the basin. The combination of the two systems results in a higher efficiency and lower power costs without complicating the necessary equipment. The gentle treatment improves the flocculation and the degree of purification.

Abstract: Novel modified intact erythrocytes (MIE) contain allosteric effectors (AE) which are irreversibly incorporated with the aid of lipid vesibles. The AE are bonded to the haemoglobin in the MIE. MIE increase oxygen supply to tissues. They can be used for treatment of (1) reduced oxygen partial pressure in the respiratory tract (e.g. for mountain climbers and astronauts), (2) reduced oxygen exchange surface (redn. of the no. of lung alveoli due to pulmonary emphysema, (3) increased resistance to oxygen diffusion in the lungs (pneumonia, asthma), (4) reduced oxygen transport ability (erythropenia, anaemia, arteriovenous shunts), (5) blood circulation disorders (arteriosclerosis, thromoembolism, organ infarcts, ischaemia) and (6) increased haemoglobin affinity for oxygen (haemoglobin mutations, chemical modification of N-terminal aminoacids in the haemoglobin chain, e.g. diabetes, melitus, enzyme defects in erthrocytes). They can also be used for accelerating detoxification processes; for reducing the affinity of transplanted blood for oxygen (transfusions, shock states) and for improving radiotherapy of cancer. The MIE can be incorporated in blood or preserved blood, or can be administered intravenously in a carrier liquid.
