Title: Percussion welding appts., esp. for electric contacts - where workpieces are immersed in water to reduce noise level
Inventor: HEIDER ERIC EWALD
IPC: B23K9/20
Filed: 1977-12-23
Abstract: One piece (a) being welded is mounted on the bottom end of an upper electrode (a1) driven downwards by a pneumatic cylinder until a limit switch energises an electromagnet to provide the impact. The second piece (b) is located on top of a second, stationary electrode (b1); and piece (b) has a small projection (bp) through which high electric current flows. During the explosion and evapn. of projection (bp) by the electric arc, the two pieces (a, b) are immersed in a water tank which is lifted by an air cylinder during the process. Electrode (b1) is pref. surrounded by a sealed bellows which permits the water tank to be driven vertically along this electrode (b1) to immerse pieces (a, b). After welding, the tank is lowered ready for welding the next pair of pieces (a, b). Used for welding an AgCdO contact (a) to a connecting piece or substrate. A pronounced redn. in noise is achieved, and fumes are collected in the water.

Title: Closed loop fuel control for IC engine - has oxygen sensor downstream of carburettor providing signal for adjusting fuel supply
Inventor: BARNARD DANIEL D
IPC: F02D41/14
Filed: 1978-01-10
Abstract: After the fuel is mixed with the air in the mixture control unit, the resultant mixture is distributed to the several cylinders of the engine by an intake manifold. Positioned in the intake manifold and responsive to the air-fuel mixture discharging from the mixture control unit is an air/fuel ratio sensor. The sensor generates an electrical signal corresponding to the actual air/fuel ratio of the mixture for applying the signal to the fuel control. This continuously maintains the actual air/fuel ratio in accordance with the desired air/fuel ratio, without any delay in the response time of the fuel management system due to the transport time of the fuel mixture or its resultant mixture to reach a sensor.

Title: Oil filter casing - with crosspiece and snap fit insert for easy element exchange
Inventor: BRUCKER WOLFGANG
IPC: B01D29/11
Filed: 1978-04-13
Abstract: An oil filter casing for the servo system of a motor vehicle has the filter element suspended from a crosspiece with an insert via a spring so that the latter can be compressed in case of excessive pressure build-up in the filter.

Title: Stereophonic playback with compensation for loudspeaker spacing - has frequency-selective mixing of left and right sound channels and phase inversion
Inventor: NISHIKAWA MASAO
IPC: H04S1/00
Filed: 1978-05-24
Abstract: The incoming signals (AL, AR) pass simultaneously to their respective control units (6, 7) and bandpass filters (8, 9). The former control the volume of lower and/or higher frequency components when necessary, and invert the phase of the complete signal. The filters (8, 9) attenuate the lower and higher frequencies and pass the remaining left and right signals to the right (11) and left (10) signal mixers respectively. The mixed signals are amplified (4, 5) and go to loudspeakers (1, 2) in the normal way. Stereophonic perception is improved in cases where the distance between the two loudspeakers is small.

Title: Mass flow controller automatic calibration factor correction - by comparing gas wt. lost with wt. from integrated flow using computer
Inventor: WILDEN ROLF ING GRAD
IPC: G01F25/00
Filed: 1979-08-10
Abstract: A flow measurement arrangement for gases and vapours uses generation of automatic correction values for the calibration factor of mass flow controllers used with different gases or vapours whose characteristics vary linearly or otherwise as they condense. The flow through the mass flow controller is integrated by a computer whilst the weight lost by the supplying gas container is measured by the computer. The total flow value is then converted to an equivalent wt. and compared with the measured wt. loss. A resulting difference within permissible tolerance limits is used to form a corrected calibration factor. If the difference exceeds a permitted tolerance threshold a fault is indicated. The computer also generates the flow regulation signal.
