Title: Moving cards positively in information storage - by impulsed air jets inside rotating profiled drum
Inventor: ULITZSCH FRITZ DIPL ING
IPC: G06K13/08
Filed: 1974-11-07
Abstract: A device for transporting strip or card recording carriers for information storage has free access, the information carriers can be opt. cleared from a store and, by means of an internal drum, passed by a processing station and returned to the same store.

Title: Surface treatment of film strip - eg embossing smoothing
Inventor: THALLMAIER MANFRED DR
IPC: C14B1/56
Filed: 1974-11-30
Abstract: In the surface treatment of strip material by continuously pressing the moving strip against a rotatable treatment roll with a corresponding surface e.g. an embossing or a smoothing roll, the strip material runs over the surface of the treatment roll on which it ha an angle of wrap and produces the necessary pressure by the tension therein. Permits material of low elasticity and strength which is difficult to process with the usual embossing or smoothing rolls, to be surface treated without risk of creasing.

Title: Determining TDC position of IC engines - by measuring position of two other pistons half-way down bore
Inventor: GRIKSCHEIT HENRY WILLIAM
IPC: G01M15/06
Filed: 1975-03-26
Abstract: Determination of the top dead center is made on the basis of movement of pistons in other cylinders in the position at or near the mid-stroke of the piston when the movement of the piston for the same angle of crankshaft rotation is the largest and when such movement referred to the position of the piston in the selected cylinder enables marking position of the top dead center of the piston in such selected cylinder with much greater precision. Linear transformers are used to measure the position of two pistons having a 90 deg. relationship to the reference piston, and the outputs from the up and down moving pistons are summed at give a null point, indicating TDC of the reference piston.

Title: Hydraulic slide valve with two rate spring - weak springs control initial travel, strong spring controls end travel
Inventor: RICHTER RUDOLF
IPC: F16K11/07
Filed: 1975-04-16
Abstract: The hydraulic slide valve (1) has a slider (2) which has two weak control springs (14, 15) and a strong spring (11). When the slider (2) is moved downwards from the null point the spring carrier (12) and the spring carrier (10) move the slider so that the compression of the weak spring (15) is unaffected, but the lower weak spring (14) is compressed by the movement of the strong spring carrier (17). When this carrier (17) abuts on the surface (16) of the weak spring carrier (13) the strong spring (11) comes into play and controls any further movement of the slider (2). With upward movement of the slider (2), the weak spring (15) is compressed before the strong spring (11) comes into play.

Title: Digital filter with threshold RC circuit - feeds COSMOS gates whose output is same as input for inputs in pass band
Inventor: HAUBNER GEORG ING GRAD
IPC: H03H11/04
Filed: 1975-09-03
Abstract: The digital filter has the input pulses which may have been derived from a sinusoidal input signal applied to an RC circuit (1, 3) that measures the time duration of each pulse by responding at a given threshold. The RC circuit output is coupled to a COSMOS gate circuit (4-6) whose digital output signal (UA) is the same as the input signal (UE) provided the frequency lies in the passband. The RC circuit and threshold can be altered to change the passband whilst in use. Several such low pass digital filter circuits can be connected together to make bandpass, bandstop or high pass filters.
