Patent DE-2350536-A1 (DE)
Title: Multi purpose adjustable snorkel - with hinged tube to enable swimmer to lie on back as well as on front
Inventor: SANDVOSS HELMUT
IPC: B63C11/20
Filed: 1973-10-09
Abstract: The snorkel has a mouthpiece joined to a flexible bent tube in which is located a rigid plastic section. This has an adjustable sucker positioned along it to secure the snorkel on the glass of the face mask. The upper end of the snorkel is a bent tube located in the top of the rigid section by a water-tight coupling which allows the upper section to rotate. The swimmer can then use the snorkel either swimming face down or on his back. This enables the snorkel to be used by life savers in heavy seas. The flexible snorkel tube positioned in front of the facemask provides added protection if the swimmer should collide with debris in the water.

Title: Heat-engine operation with low-boiling liquid - which evaporates in working cycle expands in piston engine and is returned to cycle
Inventor: HAEBERLE WILHELM
IPC: F01K17/00
Filed: 1974-01-19
Abstract: Heat-engine is operated using a low-boiling liquid which is heated in a working cycle and transformed into gas, that flows to a piston engine in which it is expanded. The gas flowing out of the piston engine is fed into the cycle preferably via a supply container and/or feed pump. Preferably, the cycle is divided into two separate sections, each with low-boiling liquid, and interconnected by heat exchangers. The first section of the cycle, taking up heat energy directly, has heat pump(s) and following second section, feed pump(s). The piston engine is preceded by a vapour jet pump in the working cycle. Working temp. and cost of equipment are low.

Title: Protection of pressurised pipeline by pressure balancing - has pressurised jackets subjected to same pressure as the pipe
Inventor: GYOERY KALMAN
IPC: F17D5/04
Filed: 1974-02-28
Abstract: The pipeline carrying pressurised fluid, especially a pipeline used in nuclear plant is protected against fracture by balancing the pressure within the pipeline by external pressure. For this purpose the pipeline is enclosed into a jacketed pipe leaving a gap between the two pipes. This annular gap is filled with fluied at the same pressure as within the pipeline. This balanced pressure reduces fatigue and other stresses within the pressurised pipeline and protects it against accidental fracture. This is of especial importance when the pipeline carries radioactive material which on escaping contaminates the environment. Any escaping material due to a fracture is collected by the surrounding material and removed safely.

Title: Curtain for windows preventing insect entry - has straightening metal insert in curtain edging
Inventor: VICK JUERGEN
IPC: E06B9/54
Filed: 1974-03-12
Abstract: The curtain for preventing entry of insects is made from woven plastics fabric which is wound on a roller. The curtain edging has a narrow flexible metal strip which is firmly attached to the edgeing by seewing, adhesive bonding or welding. This strip is arranged diagonally within the edging so that it forms a uniform, compact pattern when wound on the roller. The fabric is tensioned by a spiral spring within the winding cylinder and the edges are hence kept straight within the grooves. This arrangement seals the edges of the curtain effectively without using additional fasteners. This curtain is readily operated by elderly and/or weak persons.

Title: Holographic reproduction system allowing oblique sectional displays - involves passing X ray beam through object from several directions
Inventor: TIEMENS ULF ING GRAD
IPC: A61B6/02
Filed: 1974-04-22
Abstract: The picture is constructed by directing a beam at an object from many different discrete angles, and producing a primary picture from the images obtained. A holographic plate is also produced by positioning a photographic plate in two slanted coherent light beams, and exposing it on a plane perpendicular to the bisector of the beams interception angle but turned through various angles in that plane. The image of the original object is produced by illuminating both these plates using coherent light sources directed in beams through each of the original images on the first plate and through the developed interference pattern on the second plate.
Patent DE-2419701-A1 (DE)
Title: Transmitter finding method for radio sets in vehicles - involves transmitting special characteristic area frequency
Inventor: HEGELER WILHELM DIPL PHYS
IPC: G08G1/09
Filed: 1974-04-24
Abstract: Pulses from a pulse generator are counted by a limited capacity counter during one period and are of the characteristic area frequency of a traffic radio transmitter being received: the counter is preset to a number corresponding to the area frequency, and is filled by the pulses. A signal generator delivers a signal when the area frequency period ends with the last countable pulse; the counting pulse generator frequency is approx. half the smallest common multiple of the area frequencies, ie. approx. 297 kHz: the signal generator has a delay network whose delay time decreases with increasing frequency, so that the signal generator delivers at its output pulses with the same keying ratio irrespective of the selected area frequency, so that an integrator delivers the same switching voltage for all area frequencies.

Title: Air conditioning system with recirculating air - has heat exchanger between air entering and leaving dehumidifying cooler
Inventor: KUNZE KLAUS ING GRAD
IPC: F24F5/00
Filed: 1975-03-01
Abstract: Air is extracted from the conditioned room (1) by a fan (2) and passes through one side of a heat exchanger (3) before entering the dehumidifying cooler (4). Part of the air leaving the cooler is discharged to atmosphere (13) and the remainder passes through the other side of the heat exchanger (3). After the heat exchanger it is mixed with preheated fresh air (15) and the mixture is drawn through a filter (6) by a supply fan (2'). The fan then discharges the mixture through a reheater (7) into the conditioned space (1). The process enables a large proportion of the heat that has to be removed for dehumidification to be recovered without the energy consumption involved in the use of a heat pump.
