Title: Cold storage element for installation in cool rooms
Inventor: MEHLING ERNST
IPC: F25D3/00
Filed: 1986-04-30
Abstract: Cold storage element in a compact profiled shape which consists of a profiled container (1) filled with eutectic brine and, situated therein, a pipeline (8a-f), at least pipeline (8a-d), conducting coolant. The profiled container is statically reinforced by three transverse webs (22, 23, and 24), at least two transverse webs, and thus divided into four chambers (25, 26, 27, 28), at least into three chambers. The pipeline conducting coolant is equipped with lamellae (9, 10), and as a result the heat exchange from the brine to the coolant flowing through is significantly improved. The pipeline is guided centrally in the profiled container by pipe holders (11, 12) and is secured against vibrations as the pipe holders are supported on the inner wall of the profiled container and guided with a friction fit. The air circulation is guaranteed with quiet cooling by the special profiled shape of the cold storage element and by the free space enlargement associated therewith between the individual cold storage elements. The known ice crystal formation which forms between the free spaces of the cold storage elements is greatly reduced and partly eliminated by the invention so that the required cold radiation is provided for a greater time. <IMAGE>

Title: Production apparatus for multi-string puppets
IPC: A63H3/18
Filed: 1986-05-13
Abstract: A production apparatus for multi-string puppets has at least one puppet (1) suspended on strings, whose front legs (2) and/or rear legs (4) are pivotable relative to the body of the puppet (1), a mechanism (8) raising and lowering the strings of the puppet (1) by defined distances and in a defined sequence, which is connected to a drive, and a floor (9) moving under the puppet (1) substantially in the direction of the longitudinal median plane of the puppet (1), on which the feet (3, 4) of the puppet (1) are supported. In order to simplify the mechanism for moving the strings while achieving a lifelike movement sequence for the puppet, the latter is suspended on two strings (6, 7) in its longitudinal median plane, of which the first string (6) engages on the body of the puppet (1) in front of the centre of gravity of the puppet and the second string (7) behind the centre of gravity of the puppet, and these strings (6, 7) are attached to the arms (12, 13) of a two-armed lever which can be driven to pivot about an axis (11) extending transversely to the longitudinal median plane of the puppet (1). <IMAGE>
Patent DE-3620851-A1 (DE)
Title: Gas turbine jet engine
Inventor: WEBER FRANZ-JOSEF
IPC: F01D1/02
Filed: 1986-06-21
Abstract: The subject matter of the invention is a gas turbine jet engine which is designed to be of the bypass type and has a plurality of high-pressure turbine stages which are arranged one behind the other and have combustion chambers in each stage, which are connected to the compressor outlet by means of pipes. However, in this case, when the combustion chambers are aligned, it is impossible to achieve sufficient pressure drop from stage to stage and it is thus impossible to achieve the desired performance. According to the invention, a guide ring which is passed out of the casing of the turbine housing is arranged behind each turbine wheel in the high-pressure stages, and openings are arranged outside said guide ring in the combustion gas-jet region of the combustion chambers in the casing of the turbine housing, to which openings combustion gas guide pipes are connected which lead into the low-pressure section of the gas turbine. This invention allows the mass flow and thus the performance of gas turbines to be increased by the summation of turbine wheels, which are as small as possible and can therefore be coped with technically well, in the high-pressure stage. This engine is particularly well suited as an engine for supersonic aircraft and as a gas generator for thermal power stations.

Title: Lithotripter with an integrated locating device
Inventor: HASSLER DIETRICH DIPL ING
IPC: A61B17/22
Filed: 1987-02-04
Abstract: The lithotripter is provided for breaking up a concretion (19) in the human body (17). It comprises a shock wave pulse-emitting shock wave source (1) and a lens (11) which serves as focusing device for the shock wave pulses. In front of the lens (11), viewed in the direction of propagation of the shock wave pulses, a polyvinylidene fluoride film (33) with areas which are piezoelectrically activated in array form is arranged as receiver. The polvinylidene fluoride film (33) is connected to an ultrasonic reception circuit. By means of time-delay control, phased-array reception is possible. Behind the lens (11) and at its edge, at least one cut-out (e.g. 37a) of an ultrasonic ring array (37) is provided, which cut-out is connected to an ultrasonic transmitter for emitting an ultrasonic locating signal. The advantage of this device is that during the lithotripsy treatment continuous monitoring of the position of the concretion (19) in or near to the focus (F) of the lens (11) can be performed. By rotating the film array (33) about the main axis (25) observation in a plurality of planes is possible. <IMAGE>

Patent DE-3716480-A1 (DE)
Title: Lifesaving system for/on ships
IPC: B63B23/40
Filed: 1987-05-16
Abstract: For rescuing passengers in an emergency, until now the lifeboats have been brought into boarding position by means of davits, which is complicated and time-consuming. The passengers can then board the lifeboats, but are exposed to the elements (wind, weather, darkness), resulting in mental stress in addition to the panic caused by the emergency, and making the evacuation more difficult. The new lifesaving system is intended to greatly reduce the time for evacuation, and be more convenient for the passengers, as well as reducing anxiety. In the new lifesaving system, the lifeboats (2) are suspended on the port and starboard sides under a deck (4) that extends outwards beyond the hull (3), in an operational position where they can be boarded by the passengers for evacuation at any time from this deck (4), and lowered into the water (14) alongside the hull (3) (Fig. 2). This lifesaving system allows the lifeboats to be boarded immediately from a protected area in case of an emergency, which shortens the time for evacuation and makes this considerably less unpleasant (anxiety-reducing) and safer for the passengers. <IMAGE>

Title: Mechanical governor for an internal combustion engine with an adjustable torque-control device
Inventor: APWISCH HORST
IPC: F02D1/10
Filed: 1988-02-24
Abstract: In diesel engines an adjustment of the torque curve in accordance with different applications and the smoke limit of the engine is desirable. Furthermore, the torque curve varies from engine to engine due to the cumulative effect of manufacturing tolerances for injection system parts and governor components. The adjustable torque control is achieved by a deformation of a specially designed roller lever with a bending arm, it being possible to vary the bending axis by means of an adjustable lever arm on the torque-control lever, as a result of which, as the engine speed increases, the roller lever displaces the control rod of the injection pump in the direction of reduced fuel delivery. By means of an adjustable torque control on the governor, it is possible to correct the fuel injection quantity and to adjust the desired set torque curve. <IMAGE>
