Title: Range finder for SLR camera - has inclined transparent plate with reflecting parts for partial images
Inventor: ROTH JOHANN
IPC: G03B13/18
Filed: 1973-12-04
Abstract: A transparent plate is set at an angle in the viewfinder light path in the SLR camera. Part of the bottom surface and part of the top surface are silvered so that two partial images are obtained. If the incident rays from the two partial images are parallel then the resulting images are overlapped and the camera is in focus. Any slight out of focus condition is magnified by the refraction in the block to produce two images in the viewfinder. The system is simple to operate and the user simply alters the focus and distance controls on the camera to produce coincident images.

Title: Photoelectric code emitter for movements in two co-ordinates - with optical components between light source and receivers uses polarising beam splitter
Inventor: HOCK FROMUND DIPL PHYS
IPC: G01B11/00
Filed: 1974-07-25
Abstract: The pickup performance of an emitter is extended to the coded measurement in two mutually independent longitudinal or angular co-ordinates of a moving object, instead of being restricted to one degree of freedom, as hitherto. Between a light source and photo electric receivers with their associated code plates, optical components are interposed. These include a polarising dividing cube on which light from the source falls from a collector lens and is then passed through index plates to mirrors and a ray combiner. Light passes then to a divider and is directed through a telescope objective to and from a prism divider which moves with the object. A polarising dividing cube between the divider and the code plates separates signals into their co-ordinate directions.

Title: Voltage controlled square wave shifter - uses integrating and comparison tettechnique toto give frequency independent characteristic
Inventor: FRANCKE ERWIN
IPC: H03K7/04
Filed: 1975-10-10
Abstract: A voltage controlled square wave phase shifting network uses an integrating and comparison techniques which can be developed to a frequency independent form of the network. In the basic network the alternating input voltage is squared in a suitable comparator (14) and the output is integrated (16) to produce a symmetrical sawtooth waveform. A chopper (11) is used to produce a square wave of the same frequency from the control voltage input (Ust) and the integrated waveform is compared (12) with the chopped waveform to produce the required voltage dependent phase shifted output. The network can be developed using a control amplifier (17) in a feedback loop around the integrator (16) to make the network operation independent of the input frequency.

Title: Landing point indicator for ski jumps - uses buried transceiver loop with inductive coupling by tuned circuit on ski (SW 1.8.77)
Inventor: SCHMALL KARL HEINZ
IPC: G01S11/12
Filed: 1976-02-23
Abstract: The landing-point indicator for ski jumps consists of a detector strip (1b) laid underneath the snow between the limits of the landing area. A number of parallel pick-up wires at 10 cm intervals are laid across the landing strip (3) and are connected to resonant circuits. Each receiver circuit is scanned in turn at high speed by an interrogator connected to an indicator. A continuous transmitter loop (2) with a serpentine pattern is arranged alongside the receiver wires so that each wire is bounded by anti-phase legs of the transmitter wire. Thus, no signal, from a high-frequency generator connected to the loop, is detected by the pick-up wires. The jumper's ski is fitted with a simple, passive resonant circuit (12) comprising a coil and capacitor which is closed by a pressure switch at the moment of landing. The circuit thus bridges the landing strip transmitter loop and the nearest receiver wire by induction and energises the indicator.
