Patent DE-2640396-A1 (DE)
Title: Self-processing camera with electromagnetic shutter - has mechanical coupling to shutter blades with exposure control circuit operating with single electromagnet
Inventor: ETTISCHER HELMUT
IPC: G03B9/16
Filed: 1976-09-08
Abstract: The self-processing compact camera has a single electromagnet which not only sets the aperture but also operates the shutter timing.

Title: Improving countercurrent diffusion by material pulsation - using unequal half periods from a cam operated piston, e.g. for extn. or gas-liq. contact process
Inventor: NICOLOIU MIRCEA DIPL ING
IPC: B01D11/04
Filed: 1977-04-23
Abstract: A method for intensifying mass exchange in diffusion processes and of increasing the speed of movement of the continuous phases in counter-current processes involves pulsating the materials involved. With a pulsation frequency between 5-150 Hz and an amplitude determined by the process, the time in which the compression, upward stroke or half period (lambda/2), takes place is varied from the time for the decompression, downward stroke or second half period (lambda/2)2. The ratio of such half periods (lambda/2)1/(lambda/2)2 is 0.1-20. The half periods are so chosen that the first half period promotes the mass exchange and the second half period accelerates the counter-current speed of the dispersed phases. Used in counter-current diffusion processes, such as extraction processes or gas-liquid contact. The contact surfaces can be regulated by the gas bubble size according to requirements; column diameter can be increased; the phases are dispersed uniformly across the column.

Title: Tennis racket handle with perforated surface - has suction effect to absorb perspiration with alternate compression and relaxation
Inventor: KRIEG BENNO PROF DR
IPC: A63B60/14
Filed: 1978-02-06
Abstract: The handle of a tennis racket is covered with a grip of leather or similar material. When such a racket is used the perspiration from the user's hand tends to cause the handle to slip. This tendency can be overcome by making a large number of small holes (1b) in the surface (1a) of the leather. When the leather is compressed and then relaxed by the grip of the player's hand a suction is created which absorbs the perspiration and so prevents any slip.

Title: Combined standing wave ratio meter and wattmeter for transmitters - has adder and subtraction stage with divider connected to directional coupler
Inventor: MORIWAKI HIRONOBU
IPC: G01R27/06
Filed: 1978-05-03
Abstract: The direct-reading standing wave ratio meter, esp. for radio transmitters consists of a directional coupler(1) which is connected between a transmitter and an antenna. The coupler has two terminals, at which appear forward and reflected voltage components(1a, 1b). These outputs are buffered (A, A') and connected to the inputs of adders and subtraction circuits(2, 3). The outputs of the addition and subtraction circuits are taken to the respective inputs of a divider circuit(4). The output of the divider(4c) is available to drive an indicating instrument - analogue or digital - direct to display the SWR at the coupler. By throwing a switch(S1-4) to a second position(b) and introducing a 1 Volt source at the divider stage, the circuit can also provide a direct reading of the power of the forward wave.

Title: Oil-fired boiler flame tube - has holding ribs sliding axially on burner neck to increase back pressure in burner chamber
Inventor: SPECHT WOLFGANG
IPC: F24H9/18

Title: IC engine preheater for heavy fuel - has mixture vaporised using exhaust-heated air with quantity controlled by shutter
Inventor: BAUR EDUARD DR ING
IPC: F02M31/18
Filed: 1978-07-19
Abstract: The burner is for mixture of medium-heavy hydrocarbons esp. for IC engines, first heating the mixture above its boiling point. Heat for this comes from air flowing (37, 37a) along passages between the exhaust pipe (21) and a coaxial sleeve. Part of this air flows into the adjoining vaporising chamber(S), mixing with fuel vapour before flowing on (22) to the engine. The remainder bypasses (39) the chamber and dilutes the mixture. Total air inflow is controlled, e.g. by a shutter, as is cooling air flow (42, 44) through a casing enclosing the air sleeve.

Title: Touch and close fastener prodn. - using polymeric strips with elongate U=shaped monofilaments pressed and bonded into strips at guides
Inventor: KALLEBERG MELVIN O
IPC: A44B18/00
Filed: 1978-08-24
Abstract: Two non-fibrous polymeric strips are moved from opposite directions around parallel curved spaced guides and away from the latter in the same direction along parallel paths. Spaced parallel lines of polymeric filaments are fed between the spaced guides from the sides opposite the parallel paths and parallel to them. The U-shaped lengths of filaments are alternately pressed into engagement with each of the strips. The U-shaped segments are bonded to the strips so that lengthe of the monofilaments between the U-shaped segments extend normally between the strips as the latter move along the parallel paths. The monofilaments are severed midway between the strips to form two brush-like halves, and the newly severed ends projecting from the strips heated to form heads with curved surfaces opposite the strips.
