Title: Reflection-type silencer for IC engines - perforated partition separates two portions and supports a central tube
Inventor: RENZ WERNER
IPC: F01N1/08
Filed: 1975-04-02
Abstract: The silencer comprises a cylindrical casing (1) with a smaller conical portion (4). A gas inlet pipe (5) enters the former tangentiallythe latter ends in an outlet pipe (6) of the same dia. A perforated partition (3) separates the two portions and supports a central tube (2), dia. less than half that of the casing, fixed to the inlet end cover and perforated (10) for 2/3 of its length above the partition to form holes with acute-angled flaps (11) to direct gas flow, the hole area being less than that of the holes in the partition (3). Closing the perforated part of the central tube is another perforated partition (12)after burning air to the chamber thus formed. Silencing is achieved by the changes of direction, and interaction between various frequencies.

Title: Neutral steering rear suspension for car - has trailing arms mounted in elastic pads with transverse strut to counteract slewing
Inventor: GROTEWOHL ALBERT DR ING
IPC: B60G21/05
Filed: 1975-04-11
Abstract: The rear wheels of the vehicle are supported in such a way as to provide neutral steering when cornering. This prevents undue slewing, especially when front wheel grip is lost. The effect is provided by forward directed, horizontal stays (3) at the ends of which are mounted the wheels (1, 2). The stays are located on the chassis by means of elastic pad mountings (8). The stays are further jointed by a transverse strut (5) which gives the suspension vertical rigidity while being elastic to bending moments to allow different tracking curves for the wheels.

Title: Height regulating vehicle suspension - with fluid pump operated by bump stop having two flexible bellows and nonreturn valves
Inventor: NIEMANN GERHARD ING GRAD
IPC: B60G17/027
Filed: 1975-10-08
Abstract: The coil spring of the suspension element is braced on a fluid filled volume linked to a fluid reservoir by a rigid pipe. The pipe passes through a flexible section under the bump stop. As the suspension bottoms the flexible section is compressed to pump fluid into the suspension volume. The one way flow of fluid from the reservoir is ensured by two non return valves. The system provides an automatic self levelling control without any complicated pump and regulating control. Excessive suspension extension is controlled by a relief valve which vents fluid back to the reservoir.

Patent DE-2556378-A1 (DE)
Title: Manual propulsion for becalmed sailing dinghy - with elastic end edge to rudder for low turbulence as bar is swung to and fro
Inventor: BELL KARL WALTER
IPC: B63H1/36
Filed: 1975-12-15
Abstract: The trailing edge of the rudder blade of the sailing dinghy is fitted with an elastic strip. As the rudder bar is swung backwards and forwards the rudder propels the craft forward. The elastic trailing edge reduces the turbulence to achieve a good water flow pattern, without reducing the thrust. The system enables a becalmed dinghy to be moved to the short, single handed, and without undue effort. Rigid rudder blades set up turbulence which reduces the available thrust to a small value. The elastic strip can be part of a one piece rudder blade, with the end narrower for flexibility.
Patent DE-2557320-A1 (DE)
Title: Lock for tilting and rotating window frames - has locking pin slot to eliminate play and ensure stable support

IPC: E05F7/04
Filed: 1975-12-19
Abstract: The locking arrangement for tilting moving frames, is used especially for the combined tilting and rotating frames of windows or doors. The locking arrangement has a locking pin on one of the frames to be locked relative to each other. In the vicinity of the tilting axis but outside this axis is arranged the lock housing with slots for the pins. The moving frame is held securely in tilted position and its vibrations are suppressed by play free fitting of the locking pin. The slot in the housing has an extended section which is matched to the diameter (d) of the locking pin (20). This extension is a laterally curved slot section (23) for the tilted position. The rear wall (27) of the locking slot section (23) is preferably arranged at a spring support.

Patent DE-2623687-A1 (DE)
Title: Epitaxial layer thickness monitoring - by recording light interference oscillations from substrate implanted coating with different optical properties
Inventor: SUGAWARA KATSURO
IPC: C23C16/52
Filed: 1976-05-26
Abstract: To measure and control the thickness of an epitaxially grown layer on a substrate, the latter is first subjected to an ion implantation treatment to form in the substrate a layer with optical properties different from the substrate material. As the epitaxial layer, consisting of a material similar to the substrate, grows, the light emitted by the substrate is collected and recorded as an interference oscillation. The layer thickness can be calculated from the latter. This requires no reference substratum which may contaminate the epitaxial layer by impurity atoms; it enables the thickness to be checked with a very high accuracy.
Patent DE-2624677-A1 (DE)
Title: Solar water heating system - has pressureless expansion vessel above shielded by membrane and connected to collector
Inventor: KLEIN HEINZ DR ING
IPC: F24D17/00
Filed: 1976-06-02
Abstract: Appts. for utilising solar energy for water heating comprises a collector (1) through which water flows and which is exposed to solar radiation, and a heat exchanger (2) connected to it by pipes (3, 4). Above the collector and connected to the lower region of the collector by a riser pipe (13) is a pressureless expansion vessel (15). The expansion vessel is pref. shielded from the atmos. by a flexible membrane (14). If steam forms in the collector, steam pressure displaces water from the appts. into the expansion vessel. In extreme cases the whole collector may become filled with steam as long as the expansion vessel contains the displaced water. From then on, no more heat is absorbed, so that further pressure increase is prevented.

By arranging the rollers offset from the centre line of the appropriate arm, so that each roller projects on one side and bears only on that side against the adjacent fuel element, jamming is prevented.
Patent DE-2648436-A1 (DE)
Inventor: LIEPE FRIEDRICH PROF DR
IPC: B01D19/02
Filed: 1976-10-26
Abstract: The method and the apparatus for continuous foam dispersion are used in the intensive aeration of waste water and in fermentation. In order to ensure continuous dispersion of large amounts of foam of high density with little expenditure of energy, the foam is completely dispersed sequentially by frictional force, shearing force and centrifugal force. The apparatus is composed of a housing (9) having foam entry nozzles (2) and discharge channels (11, 12) for liquid and gas. In and above the foam entry nozzle are arranged two or more rotationally symmetrical perforated bodies one above the other. The rotationally symmetrical body (3) first coming into contact with the foam is firmly joined to the foam entry nozzle (2). The rotationally symmetrical body (4) immediately following is attached to a shaft (5). Each two rotationally symmetrical bodies thus attached in different manners act as a shearing pair. The uppermost rotationally symmetrical body (4) is always attached to the shaft and, on its side facing away from the foam entry nozzle, is equipped with paddles (5) for centrifugal acceleration of the remaining foam. <IMAGE>
