Title: Reduced-size loudspeaker for use in electrodynamic system - has serial resonance elements consisting of evaluated metal shells suspended in cabinet
Inventor: BSCHORR OSKAR DIPL ING
IPC: H04R1/28
Filed: 1979-11-23
Abstract: In an electrodynamic loudspeaker system a basic problem consists in making the radiation resistance of the membrane (1) in a forward direction larger than in the backwards direction. This problem is overcome by inserting into the speaker housing (4) a sufficient number of serial resonance elements (3,3a) whose impedance is smaller than that of the air volume they occupy. Closer to the membrane are suspended the resonance elements (3) which are tuned to higher frequencies whereas those (3a) tuned to low frequencies are placed further away from the membrane. These elements consist of evacuated metal shells of different sizes chosen to cover the entire audible spectrum. Due to the absorption effect of the acoustic serial resonance elements, the loudspeaker cabinet may be made smaller than would otherwise be feasible at an acceptable sound output efficiency.

Title: Rotary piston IC engine - has compressed air admitted to compressor cylinder from high pressure vessel for starting
Inventor: EICHNER RICHARD
IPC: F02B65/00
Filed: 1980-01-23
Abstract: The compressor cylinder (3) has two pipes (17,17a) connecting each end of it to the high pressure vessel (1). The pipe inlets from the vessel are controlled by ports (30,31) in a disc (19). One of the ports is also closed by a manually controlled rod (18). When this is lifted compressed air is admitted into the cylinder and moves the piston (10). This is connected to the motor piston and thus sets it in motion. A cam (28) on the chain wheel (27) driven by the motor rocks the disc (19). The air is thus admitted alternately to opposite sides of the piston to maintain the motion until ignition occurs.

Title: Temp. stabilisation system for radiation detector assembly - has cooler for removing heat from pipe enclosing detector assembly whenever pipe temp. exceeds predetermined level
Inventor: RICHTER JUN ALBERT PAUL
IPC: G05D23/24
Filed: 1980-02-09
Abstract: The system stabilisation system comprises a heat pipe enclosing the radiation detector assembly and is positioned in a dewar flask. A thermo-electric cooler is joined to one end of the heat pipe. The heat exhaust of the thermo-electric cooler is communicated to a heat dissipation device in the form of a fin assembly. A thermistor senses the temperature at the heat pipe. When the thermistor indicates a temperature in excess of that corresponding to a reference signal, a control signal is produced by a control device to cause a power source to operate the thermo-electric cooler to remove heat from the heat pipe to the fin assembly. The vacuum within the dewar flask effectively limits the environmental heat passing to the heat pipe to radiant heat.

Patent DE-3013138-A1 (DE)
Inventor: MILZ ARTHUR
IPC: F04D29/42
Filed: 1980-04-03
Abstract: The disclosure relates to a rotary pump especially for corrosive liquids including an impeller rotating in a working chamber. A spirally wound duct leads from one surface of the working chamber to the outlet pipe of the pump. The upstream end of the duct obliquely enters the working chamber, whereby the end portion of the duct is laterally open towards the chamber and forms a channel in the wall of the chamber. The duct winds helically around the rotation axis of the impeller, having an inside wall at a progressively decreasing radial distance from said rotation axis and a progressively increasing pitch when viewed in the direction of the flow. A feature is the provision of the wound duct in the form of a helix as an open groove formed on the outer surface of a solid stator body and closed by an encompassing casing. A further feature is the provision of a relatively loose, elongated drive shaft from a motor to the pump impeller disposed within a guide tube and a circumferential clearance between the shaft and the tube for leakage flow of liquid being pumped to lubricate the shaft wherein a bypass port is provided in the guide tube for return of the leakage flow upstream of a restriction in the clearance. The restriction increases pressure in the clearance to dampen lateral oscillation of the shaft in the tube. No seals are used for the shaft thereby precluding the tendency of seals to stick during prolonged rest periods.

Title: Carrier frequency supervision for communications system - in which time delayed zero cross-over points are assessed by logic system
Inventor: PARRAS KARL-HEINZ DIPL ING
IPC: H04L1/20
Filed: 1980-06-07
Abstract: The checking system is applied to a communications channel using a frequency modulated carrier oscillation. The system operates on the carrier zero crossing points. These are used to generate a series of impulses, which are differentially time delayed in an impulse delay unit (1). Some of the outputs of this unit are applied to a pulse converter (2), and all are applied to a logic circuit (3). The pulse converter feeds the circuit with a number count which may be in the form of a logic high or low. The logic output is applied to a counter (4) whose output condition changes from one state to another depending upon the logic input. The change in state, for example from a high to a low, indicates loss of carrier wave. The supervision does not add greatly to the components required for the data transmission system.

Title: Air line lubricator - with oil drip between restrictor orifice and atomising spiral
Inventor: GRUETTER WALTER
IPC: B01F5/06
Filed: 1980-09-22
Abstract: An air line lubricator to introduce a lubricant into compressed air in a pipeline consists of a container with the lubricat ad the air suppl pipe hich passes through it eccentrically. A branch pipe, leading to a composed air consuer, is joined to the supply pipe through a restrictor orifice. A tube pressurises the lubricant and raises it through a dip pipe to a control head and into a chamfered pipe at the downstream side of the orifice. A spiral in the branch pipe intensifies the oil atomisation by a swirling flow. This greatly shortens the time between the start of the lubricator and its yield of air-oil mixture so that the waiting time before tools can be operated is reduced.
