Title: Circular saw and worktable arrgt - simple method of automatically adjusting guard to suit position of saw
Inventor: SUSEMIHL ROLF
IPC: B27G19/08
Filed: 1974-09-05
Abstract: The motor driving the saw is attached to a board hinged on an axis (8) spaced from the saw, so that the amount which the saw projects above the table is set by swinging the board about that axis. To maintain the guard behind the saw blade, the plate swings about the axis of the saw with pins travelling in slots and another pin in the plate moves in a curved slot in the front cover plate of the machine, to follow a given path. A final turn in the slot in the front cover plate, away from the circular arc, draws the guard completely below the table when the saw is swung below the table, so that the work surface is then left clear.

Title: Triplicate system for display from symbol generators - gating circuit clocked to cyclically switch generator outputs to screens
Inventor: KISTER HORST
IPC: G06F11/00
Filed: 1974-10-03
Abstract: A triplicated display system for applications demanding high reliability, e.g. aircraft, avoids error and enables the facility unit to be readily identified. The system utilises three identical symbol generators each coupled to a gating circuit. The output of each gating circuit may be selectively coupled to any one of the three output display screens. The cyclic coupling of each symbol generator output with each of the display screens is effected by continuously clocking the gating circuits with a low frequency (0.5 Hz) signal. Any defective symbol generator output will produce a flickering display on all three screens and the generator may be readily located by switching each generator off in sequence.

Title: Mass flow meter for liquids and gases - uses temp. difference between two partial flows
Inventor: CHAWLA JOGINDAR MOHAN DR ING
IPC: G01F1/68
Filed: 1974-10-16
Abstract: The total flow (a) to be measured is divided between two given points (A, B) into two partial flows (G1, G2). The temp. of one of these (G1) is varied by several deg. K and heat exchange is then allowed between it and the other partial flow or the total flow. From two measurements in each case the wall and partial flow temps. of the first partial flow (G1) are determined, and the other partial flow is calculated taking into account the pressure drop between the given points which is necessarily the same for both partial flows. The division of the complete stream is such that the reduction in pressure for both divided streams is the same between the points (A and B).

Title: Continuous analysis evaluation for digital process computer - controlling charge mixing for cement kiln by fluorescence X-ray analysers
Inventor: KRUEGER AXEL
IPC: G05D11/02
Filed: 1975-06-02
Abstract: A continuous analysis evaluation system for the process computer control of the raw material mixing for the change to a rotary cement kiln takes continually samples from the feed. The energy pulses produced by X-ray fluorescence analyzers for the four principal elements Ca, Si, Fe, Al are processed to digital data. These data are fed to a process computer which controls by its output the discharge conveyors of the raw material bunkers. This eliminates errors and delays inherent in intermittent sampling. The instability caused by the zero drift which necessitaters frequent re-calibration is avoided. The system gives a reliable digital indication and process control.

Title: Hinge mechanism for bed stowed in wardrobe - has weight compensation spring and cam plate prevent hard impact when pivoting
IPC: E05F1/10
Filed: 1975-06-03
Abstract: The operating mechanism for a combined bed and wardrobe arrangement is used for swivelling the bed out of the wardrobe. The bed weight is fully compensated during the pivoting process and the bed is reliably and firmly held in the end position. Moreover, the bed does not reach the stowing position with sharp impact. A cam plate (12) is fitted into the force transmission path of the compensation spring (6). The effective radius of this cam plate varies together with the outwards rotation of the bed (2) so that the resultant force variation of the compensation spring (6) is equal to the force variation resulting from the outwards swing angle and bed weight. Springs (13) act in opposition to the weight compensation spring (6). These opposite springs become effective only when the bed has almost reached its end storing position.
