Title: Invalid bed with lifting system - has interconnected levers and drive mechanisms
Inventor: WEGENER GERHARD
IPC: A61G7/012
Filed: 1974-07-26
Abstract: A bed for sick persons with a wheeled frame, masters frame and lifting system is constructed such that each pivoted lever pair (25, 25') is mounted on the wheeled frame (10) and attached to pivoted lever drive (26, 26') mechanisms. Between the lever drive mechanism (26, 26') there is a drive coupling by means of which the lever pairs (25, 25') move in a V-type motion in directions opposed to one another. Support lever pairs are attached to support lever drives on the master frame. On each support lever drive a stabilising lever is connected by means of a link arm in the same lateral direction.

Title: Combined pants and tights - with fibres, which feel comfortable next to the skin, incorporated in body portion
Inventor: NEBEL ERHARD
IPC: D04B1/24
Filed: 1974-09-02
Abstract: Combined pants and tights comprises a body portion made of plush material of which the basic fabric is of elastic material and the loops of the plush are of rayon. As the rayon does not accept dye for the polyamide material, the colour on the inside of the body portion can be as desired, since the inner surface of the loops is covered even when these are only present in e.g. every other row. The outer surface of the body portion has the same colour as the leg portions.

Title: Complementary MOS logic circuit has inverter with two MOSFETs - in drain-drain series and depleted types gate connected to its source
Inventor: POMPER MICHAEL DIPL ING
IPC: H01L27/12
Filed: 1974-09-10
Abstract: The complementary MOS logic circuit has an inverter which is constructed from two complementary MOSFETs which are connected together at their drains to a common output terminal (3) and are connected by their sources to the oppositely-poled supply terminals (4, 6). The input signal (5) is applied to the MOSFET at the first gate. The second MOSFET (2) is depleted and has its gate connected to its source. The advantage of the logic lies in its avoiding delays arising from capacitance when connected into a chain of logic elements. The logic also has increased packing density.

Title: Catalytic engine exhaust gas treatment - with second oxidation catalyst before reduction catalyst and secondary air admission after it
Inventor: SUGIHARA KUNIHIKO
IPC: F01N13/02
Filed: 1974-11-06
Abstract: The exhaust gases of an IC engine pass through an oxidn. catalyst to oxidize part of the hydrocarbons and CO and to reduce the O2 content before entering a redn. catalyst where the N oxides are reduced. A final oxidn. catalyst stage to oxidize the hydrocarbons and CO follows after secondary air has been admitted from a blower. This prevents premature brittle fracture of the redn. catalyst when exposed to a high temp. in presence of oxygen. The system prevents pollution of the atmos. both by N oxides, CO and hydrocarbons.
Patent DE-2455848-A1 (DE)
Title: Rigid packaging vessel volume measuring device - has calibrated piston-cylinder system connected to drive
Inventor: DANIELS MANFRED DIPL PHYS DR
IPC: G01F17/00
Filed: 1974-11-26
Abstract: The piston-cylinder system stroke movement is connected with an initiator whose electric signals are proportional to the quantity of liquid expelled from the system by the piston movement. It is connected to a convertor. The cylinder is connected by a pipe to the tested vessel and a conduction electrode is attached to the pipe end, and connected to the drive control. When the conduction electrode touches the surface of the liquid level introduced into the vessel under examination an impulse is generated which switches the drive off or over. By switching over the piston-cylinder system sucks in a fresh supply of liquid ready for the next vessel.

Title: Formaldehyde separation from waste gases - by aq. phase absorption and distillation procedures
Inventor: SCHUCKMANN JOACHIM VON
IPC: B01D53/14
Filed: 1976-05-25
Abstract: The sepn. of HCHO from gases, esp. industrial waste gases, comprises passing the gases charged with HCHO through an absorber utilising an aq. phase as absorption medium for the HCHO; with drawing the aq. phase charged with HCHO, continuously or at suitable intervals, from the absorber and passing it to a distillation stage for an HCHO-enrichment process; withdrawing continuously or at suitable intervals, an HCHO-enriched phase and an aq. phase poor in HCHO; opt. cooling the latter aq. phase and returning it to the absorber thus uplacing the aq. phase withdrawn from the system with fresh aq. phase; and isolating the phase in HCHO. The process is partic. appropriate where the industrial waste bases contg. the HCHO are largely inert, e.g. air, gas mixtures not contg. O2 or contg. some O2 and organic gases such as lower alkanes. Typical process where HCHO is produced is in the prodn. of glass-fibre reinforced synthetic resins using HCHO based resin binders. The HCHO is recovered as highly concd. aq. solns. or as solid polymers e.g. para-HCHO.

Title: Error detection system for A:D convertor - compares digital signals corresponding to standard analogue signals with corresponding standard digital signals
Inventor: GASTEIGER RICHARD
IPC: H03M1/00
Filed: 1976-05-31
Abstract: The A/D convertor operates on the iterative principle. Certain analogue signals are applied to the analogue-digital convertor, and its output digital signals are compared with specified digital signals. Digital signals corresponding to the coding characteristic points to be tested are stored and applied to the input of a calibrated digital-analogue convertor. Analogue signals appearing at the calibrated digital-analogue convertor output are applied to the analogue input of the analogue-digital convertor to be tested, and digital signals appearing at its output are compared with the stored specified digital signals by a digital comparator. An error signal is delivered when the difference exceeds a specified value.

Title: Gas cooling and liquefaction plant - uses heat exchange and expands gases tapped at two points
Inventor: SKOLAUDE WERNER DIPL ING
IPC: F25J3/04
Filed: 1976-08-17
Abstract: The plant for cooling and liquefaction is used for a low b. pt. gas. This gas is compressed and cooled by heat exchange with a cold circulating gas stream. The gas is expanded through restrictor and gas streams are tapped at two different points. These streams are expanded and mixed into the cooling gas stream. The liquefaction process has low energy consumption and low investment costs. The stream from the expansion with high temp. level is mixed into the cooling gas stream at the point in the heat exchange process which is closer to the colder end of the heat exchange process. This point is closer than that point from which is tapped the gas to be cooled which is to be at lower temp. after expansion.
