Title: Independent rear wheel suspension - with extra track rods to maintain tracking when one wheel is displaced
Inventor: OHE MANFRED VON DER DIPL ING
IPC: B60G3/20
Filed: 1972-04-24
Abstract: The wheels are secured on hub sections pivotted on special joints at the ends of trailing subframes, with one sub frame on each side of the vehicle. When the whole axis is displaced the wheel tracking is easily maintained. When one wheel is displaced on one side the tracking deviations can occur. These are eliminated by the use of special track rods between the pivotted hub sections and the chassis, and are arranged so that the tracking of the wheels is maintained as closely as possible. The trailing subframes are of triangular shape, braced at two horizontal bearings inward of the sides.

Title: Safety stop for desk drawer - full width hinged top flap with manual or push rod release
Inventor: HOFFMANN DIETER
IPC: A47B88/16
Filed: 1973-06-12
Abstract: The flap consists of two sections which are suspended by freely moving hinge joints near the front and above the drawer sides. The two sections are connected by a crossbar which has a section bent forward at a right angle to the flap. The two flap sections lie at a backward slope and their lower edges slide on top of the drawer sides to hit the raised drawer back when the drawer is fully extended. The stop can only be released by deliberately lifting it over the drawer back. This is done manually or by a push rod mechanism which engages the forward angled cross bar section. The push rod mechanism can be coupled to both visual and audible warnings. When a drawer is reinserted after removal, the stop mechanism automatically drops itno the working position.
Patent DE-2331376-A1 (DE)
Title: Discharge and purification plant for open-air swimming pools - incorporates one or more surface skimmers, with pump positioned immediately behind
Inventor: BOES GUENTHER DIPL ING
IPC: E04H4/12
Filed: 1973-06-20
Abstract: The casing for the skimmer is fixed to the edge of the swimming pool, and has the skimmer positioned at its inflow side, through which the surface water passes to the inside. The rotary pump is housed inside the casing, in the liquid; and a motor attached directly to the pump is positioned above the liquid. The pump sucks the liquid inside through an opening from where it is carried through an impeller blade, through a pressure aperture into a pressure pipe leading to a filter. The pump conveys the surface water once through the ducts formed by the ridges between the skimmer housing and the pump housing. Opposite the suction opening in the pump is a connection for the bottom outlet. Throttle pieces in the top adjust the proportion of surface to bottom water. A sieve positioned above the ridges traps large impurities. A cover-plate of perforated material enables such impurities to be easily seen and removed.

Title: Wall-mounted clothes hanger peg - has spring-operated clamping jaw with inclined wedged contact face at lower edge
Inventor: STOLZ GERHARD
IPC: D06F55/00
Filed: 1973-07-24
Abstract: One half of the clothes hanger peg is fixed to the wall, whilst in the upper parts of both halves, are blind holes containing the helical compression spring which keeps the jaws of the peg together. The lower outwardly inclined wedged contact face of the movable peg half can be pushed up by the fingers of the user to open the peg against spring action, so that a garment can be inserted. On letting go the movable jaw, the peg automatically closes and the teeth on the inside of the jaws keep the garment in position. To release the garment, the upper part of the movable jaw is pressed back towards the fixed part against spring pressure. The lower end of the fixed jaw is turned up to form a coat hook.

Patent DE-2340524-A1 (DE)
Title: Ventilator motor speed regulator triac switch - is protected against overloads by sawtooth voltage proportional to temperature difference
Inventor: WAGNER GERD WILHELM
IPC: H02P25/10
Filed: 1973-08-10
Abstract: The speed-regulating circuit, for a motor driving a ventilator fan, has a periodic sawtooth voltage produced across a capacitor. The slope of the rising edge of the sawtooth voltage depends upon the difference between the actual temperature and a reference level in such a way that it is less with an increasing difference and greater with a decreasing difference. The sawtooth voltage triggers a diode which is coupled over an amplifying transistor to the control traic's gate. The triac is connected in series with the motor's winding via a choke. The choke is used to generate a control voltage for a switching circuit which short circuits the capacitor after this control voltage has died away. The regulating circuit protects the triac from overloads.

Title: Transfer of gases between liquid and gaseous streams - using a spray nozzle to contact the two streams
Inventor: SCHIERJOTT GUENTER DR TECHN
IPC: B01D53/14
Filed: 1973-09-25
Abstract: A component in a gas stream is absorbed in a liquid, or a gaseous component desorbed from a liquid into a carrier gas by passing the liquid and the gas into a common pipe leading to a nozzle which sprays the gas/liquid mix. into a chamber. The action of the nozzle creates large interfacial area for mass transfer. The liquid and gas separate and leave the chamber through separate exits. Method is useful in chemical analysis for a gaseous component where the component may be more easily identified or measured when transferred e.g. where other cpds., present in the original mixt. may interfere with the analysis.

Title: Infra-red gas analyser - is for modulated light with split differential detector and cancels zero drifts
Inventor: HUMMEL HEINZ DR RER NAT
IPC: G01N21/37
Filed: 1974-03-05
Abstract: The infrared gas analysis instrument is for the analysis of gas mixtures by their infra-red absorption, having a very stable zero point. Light from a source is modulated by a modulator and passes through a two layer differential detector with the measuring cell located between the two layers. The signal from the first sensitive layer represents the incident signal and that from the second layer the incident signal less the specimen absorption effect, so that variations in the incident signal are balanced out by the differential action of the detector.

Title: Measuring operation supervision in time - by digital display and print-out in fixed time intervals separated by zero resets
Inventor: STARK GEORG ING GRAD
IPC: G01D9/16
Filed: 1974-07-22
Abstract: The progress of a measuring operation as a function of time, such as that of the enzyme activity where the substrate concn. is determined at various times and the enzyme activity is given as the initial rate of change of the substrate concn. in time, is recorded by measuring the para meter differences automatically in preset successive time intervals in digital form. Once its value has been recorded, it is automatically reset to zero within a short time compared with the measuring period interval. This indicates at once whether there is a linear connection between measured value and time and how great the value is. It requires only simple appts. as an attachment to an expensive photometer equipped with a computer.
