Title: Shelved store feed installation - has battery driven truck with sensors for controlling truck speed on detection of obstacle in path
Inventor: KRUPS FRIEDHELM
IPC: B65G1/06
Filed: 1979-07-27
Abstract: The shelves form storage channels of adjacent and stacked racks for retaining loads with flat undersides. The installation contains at least one battery driven, controllable, flat transport truck, which can enter the shelf racks on rails. It has a lifting platform for load storage when raised in the upper position, and for inserting under the load when in the lower position. A travelling stacker retains the truck at the end of the shelf racks, while contactless sensors actuate the truck control. The speed can be reduced under the control of the sensors, on approaching an obstacle depending on the distance. The speed reduction is carried out in steps switched during approach by the sensors. The speed reduction may be infinitely variable. Certain sensors may provide braking during the truck approach.

Patent DE-3000378-A1 (DE)
Inventor: MAROLD THOMAS DIPL PHYS
IPC: H03M1/00
Filed: 1980-01-07
Abstract: Below the phototransistors (O, N1 to N7 and V1 to V7), there are openings in a mask (M), of which the opening (U) allocated to a photo- transistor (O) exists several times and is visible and acts as raster. The V receivers of a first group (N1; N2; N3; V1; V2; V3) provide for leading scanning and the N receivers provide for lagging scanning. These receivers are all offset by +/- 1/4 pitch constant +/- 16 pitch intervals (line widths) of the zero track compared with the reading index I. The offset is an integral multiple of the pitch constant of tracks 1 to 3 and does not produce any change in the analysis result. A second receiver group comprises phototransistors (N4 to N7 and V4 to V7). The offset here comprises +/- 4 pitch intervals of the finest track. The detector arrangement maintains the minimum permissible receiver spacing in the entire receiver array, taking into consideration the dimensions of the individual receivers. The dimensions of the illuminated array with the detector arrangement are not exceeded. The tolerance in the position in the position of the receivers and the associated electronics can be matched to one another and is reduced overall. <IMAGE>

Title: Template tracer for copying machine tool - is movable between limit switches allowing fast tracing by slow positioning against template
Inventor: DORMEHL ERICH
IPC: B23Q35/26
Filed: 1980-08-06
Abstract: The template follower assembly (2) is intended for a copying operation on a machine tool. It comprises a feeler (10) at the end of a rod (3) which is axially slidable in a carrier (1) to produce an electrical signal (limit switches 8,9). As the carrier (1) is moved at high speed towards the template, initial contact of the feeler produces a first signal (switch 8) causing the rod (3) to be withdrawn (stop 6 to stop 7) and the carrier to be switched to low speed. When the rod arrives in its working position (7), the second switch (9) activates the start of the copying operation.

Title: Correlating system for two speed related signals - passes signals to two registers whose stage outputs are multiplied and summed
Inventor: MASSEN ROBERT DR
IPC: G06F17/15
Filed: 1980-08-12
Abstract: The first signal (Sx(t)) is passed to the input of a first sampling circuit (14) comprising aD-flip-flop and the input of a second sampling circuit (15a) also comprising a D-flip-flop. The output of the second sampling circuit is connected to the input of a third sampling circuit (15b) also a D-flip-flop. A string of such D-flip-flops is formed to produce a register. The outputs of each flip-flop in the register are combined with the output of the first flip-flop in a multiplier (16a-16h). The resulting products are passed via a distributor (17) to corresp. cells in a summation memory (18) where they are added separately. The first signal is sampled at a rate whose frequency is a multiple of that at which the second signal is sampled.. This correlation techniques can be used for contactless speed measuring of moving objects and fluids in pipe leads. Noise signals can be supplied from two sensors spaced along the path. Correlation is achieved using few components.

Title: Microscope depth of focus increasing system - involves axial oscillation of specimen, illuminated by frequency interlocked stroboscopic light source
Inventor: STUEMER GERD
IPC: G02B21/06

Title: Device enabling authorised persons to switch on drives in mining operations
Inventor: ORMANNS SIEGFRIED
IPC: E21C35/04
Filed: 1981-01-15
Abstract: In addition to a manually operated switching element (1), a transmitting/receiving device (3) is arranged on a control panel (5), the transmitting section of which sends out a continuous high-frequency signal and the receiving section of which passes received signals in a frequency band deviating from the transmitted frequency. A transducer (4) which can be introduced into the field of oscillation of the transmitter converts the transmitted frequency into a frequency within the pass band of the receiver. If this frequency reaches the receiver, an unlocking device is activated which unlocks the switching element (1). This limits the operation of the switching element to the circle of authorised persons and particularly simplifies the operation for these persons. <IMAGE>
