Title: Dust sampling device for chimneys or ducts - has quick closure valve producing shock waves in sampling tube
Inventor: AUZAC GERARD D
IPC: G01N1/22
Filed: 1975-12-09
Abstract: Device comprises a sampling tube having a mouthpiece, at one end and a suction blower at the other end. The mouthpiece is equipped with a closure valve, which is closed at least once during each dust-removal period, the blower being kept in operation during this time. Pref. the valve is opened and closed at the start and end of a removal (sampling) period and, more specifically, may be closed and then reopened rapidly just before the final closure at the end of the period. As a variant, a cycle of repeated short closure and short opening may be carried out during or throughout the sampling period. Used in particular for monitoring discharges to atmosphere. The use of a rapidly closing and opening valve ensures that shock waves travel along the sampling tube, thus dislodging any dust which might adhere to the inner face of the tube, causing accumulation of dust and distortion to the results of the test.

Title: Constant current circuit for supplying telephone terminals - has high symmetry AC attenuation without complex symmetry restoring controls
IPC: H04M19/00
Filed: 1976-08-02
Abstract: The constant current circuit, for supplying telephone terminals from a central exchange, achieves high symmetry AC attenuation without using complex controls to maintain symmetry. A transistorised constant DC current source (T1) is connected into one wire (a) of the loop circuit and acts also as a constant AC current source. The second wire (b) contains a transistorised constant DC voltage source (T2) that also acts as a constant AC current source. The transistors are IGFETs. The advantage lies in the stability achieved by using only one constant DC current source - and thereby preventing asymmetry arising from any opposite regulation that might occur with two sources in series.

Title: Mechanical sorting of living cells - using photoelectric classification to control high speed, continuous sepn. based on physiological structure
Inventor: LENZ PETER
IPC: G01N15/14
Filed: 1976-11-19
Abstract: Liq. contg. unsorted cells is passed through a transparent channel having a rectangular cross-section sized to make the cells travel in single file. A beam of light is used to form n optical image of part of the channel contg. cells. A very narrow, transverse one of hte image is viewed photoelectrically, to detect variations in luminous intensity via the cells. Each cell is checked in a sereis of successive, transverse planes and the resultant signals relayed via a transducer to a programmed logic circuit which classifies the cell. The classified cell is then diverted to a corresponding outlet for a sorted group of cells. The transparent channel is pref. formed by slitting a thin, flexible, transparent sheet, stretching the sheet to pull apart the lips of hte slit to correct channel spacing, e.g. 10 mu m, and clamping the sheet between two transparent blocks, e.g. quartz, to hold the channel at that width. The process is used in microbiological laboratories for the sorting of living cells and gives high speed, continuous operation. Previous, ultrasonic sorting was limited to very generalised criteria whereas the new process takes detailed account of the physiological structure of a cell once classified, cells are sorted by simple mechanical diverters.

Title: Solar heating installation using a heat exchanger - to transfer the heat from a reservoir to an air heating system
IPC: F24D11/00
Filed: 1977-03-01
Abstract: The heat exchanger is for a solar heating installation which has a heat source, such as a solar trap, the heat from which is transmitted by a fluid heat carrier to the heat reservoir. The heat energy thus accumulated is used in a hot air system, the walls of the reservoir being constructed to allow thermal exchange across the walls and circulation of air around them. Vanes are placed between the reservoir and the outer chamber to ensure the circulation of the air from the fresh air inlet at the bottom to the warm air outlet at the top. The heat exchanger avoids the use of large cumbersome parts to use the heat energy. It provides a convenient and economical system for heating air and is itself economical to produce.

To vary thrust direction the lever is rotated, altering the radial distance (a) between knife edge and individual transmitter axes and thence the thrust resultant.
Patent FR-2349870-A1 (FR)
IPC: G04G13/02
Filed: 1977-04-29
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.
