Title: Plate heat exchanger with turbulence producing inserts - of spiral entwined wires also serving as spacers
Inventor: PETROWITSCH PERZEW LEONID
IPC: F28F1/40
Filed: 1973-07-26
Abstract: A heat exchanger comprises stacks of sheets separating the two separate duct systems; the ducts contain inserts which serve both for supporting the heat exchange plates and also for causing turbulence in the flow. These inserts, in >=1 of the duct systems are constituted of rows of twisted or plaited spiral wires. The spirals may be arranged in rows extending in two mutually perpendicular directions, the intervals being not greater than the internal dias. of the turns. Alternatively, in >=1 of the directions, the distances between the rows exceeds the internal dia. of the turns. Adequate stiffness, improved turbulence and relatively low pressure drop are obtd. A relatively small amt. of material is required.

Title: Heat control system for epidiascope - uses combination of heat reflector and absorber between lamp and stage
IPC: G03B21/06
Filed: 1973-08-02
Abstract: An optical element consisting of a heat absorbing glass is fitted between the lamp and the stage. The surface of the element facing the lamp is additionally coated with a heat reflecting layer. A similar heat reflecting coating is applied to the glass pressure plate used to hold the original flap. The design reduces the temperature of the stage and allows an original to be projected for prolonged periods without causing deterioration from excessively high temperatures. Most of the infra red radiation is removed from the light striking the original, leaving only visible light.

Title: Counting translation in telephone junction - device keys DC voltage applied to junction line wire
Inventor: SEDLMAYR OTTO
IPC: H04M15/10
Filed: 1974-01-22
Abstract: The telephone junction device controls the counting pulse generation beginning and end, and keys a d.c. voltage at a specified rate. When the called subscriber puts his receiver down, a signal e.g. flickering clearing signal, is evaluated by a switch becoming operative with a delay. A switching element controlled by this switch is inserted in the control wire passing through the counting translation. It clears the connection. A divider element in the dialling transmission of the control line connects the calling subscriber to the next dialling stage when he fails to hang up after the clearing signal, while releasing the called subscriber. The dialling input is simultaneously finished. The divider enables an additional function to be automatically carried out.

Patent DE-2416523-A1 (DE)
Title: Fail-safe command signal transmission device - enables fast response with low frequency pulses via two parallel lines
Inventor: MATEJKA JAROSLAV DIPL ING
IPC: G08C25/00
Filed: 1974-04-04
Abstract: The sending end consists of two EXCLUSIVE-OR gates fed from a pulse generator and feeding two monostables. The second input to the OR gates is connected to the command source and is quiescent at a positive voltage. The two pulses generated have coincident back-edges, are of different widths, and are negative. The OR gates thus act as inverters. The monostables generate narrow pulses from the front-edges and these are thus not coincident. The receiving end consists of an AND-gate feeding a re-triggerable monostable which is set for a reset period longer than the period of the pulses. The two lines are also connected to a lamp indicator to monitor the transmission of pulses. When the command input goes negative the OR gates cease to invert and the monostables are triggered by the positive pulse rear edges.

Title: Precision mounted courtesy switch for car door - has position in door lock with contacts closed when door slightly open
Inventor: SOWISLO HORST
IPC: H01H13/18
Filed: 1974-04-19

Title: Capacitor with ceramic dielectric - has ceramic layer bent through 180 degrees along line outside main surface symmetry axis
Inventor: FINK RUDOLF DIPL ING
IPC: H01G4/30

Abstract: The capacitor is formed by a ceramic dielectric layer, whose both main surfaces are coated with metal electrodes. Along a line inside the main surface the dielectric layer is bent through 180 deg., the line of bending being outside the symmetry of middle line of the main surface of the dielectric layer. In this manner the main surface is divided into two unequal surface regions. Preferably the electrode areas are spaced from the lay-out lines of the dielectric layer. In alternative design the electrode areas may reach up to the dielectric layer edge and continue over the other main surface. The two designs may be combined.
Patent DE-2448295-A1 (DE)
Title: Throttle valve with divided flow cross-section - has adjustable resistance to fluid flow to reduce noise
Inventor: BENDER HANS
IPC: F16K3/32
Filed: 1974-10-10
Abstract: The valve head (1) slides in a cylindrical space surrounded by a stack of corrugated discs (3) which extend from the valve seat (7) to a cover plate (8). The corrugated discs are secured at a uniform distance from each other by collars and the assembly is held together by bolts. The position of the valve head (1) determines the effective area of cross section (3) of the fluid flowing through the valve and this in turn controls the resistance to flow which can be adjusted to reduce the noise to a minimum. The use of corrugated discs closely spaced provides a high degree of resistance and a corresponding reduction in noise.

Title: Adjustable control rod for rotor blade pitch setting - with two part rod joined by threaded sleeve with different pitches
Inventor: MAUTZ KARLHEINZ
IPC: B64C27/58
Filed: 1974-12-17
Abstract: The control rod in the rotor blade pitch control linkage is made in two sections (25, 26) whose adjoining ends are threaded and located in a covering sleeve (27). The two threads (28, 29) are different so that rotation of the sleeve alters the control rod length by an amount equal to the difference in pitch, to give a very fine length adjustment for the rod. The sleeve is bored with securing holes around its rim to locate a securing peg through a slot in the one section and prevent the adjustment from slipping. This provides an even finer adjustment, with a graduated scale on the sections.
