Patent DE-2428603-A1 (DE)
Title: Automatic refractometer for ophthalmic investigations - uses polarized infra-red light and quarter-wave phase-shift window
Inventor: MUNNERLYN CHARLES R
IPC: A61B3/103
Filed: 1974-06-14
Abstract: Invisible infra-red light which leaves the eye relaxed and fully dilated is polarized by a prism then given a pattern of transversely moving stripes by rotating drum with regularly alternating opaque and transparent segments. It is focussed by a polarizing prism and lenses on the retina of the eye. The quarter-wave phase-shift window produces a retinally-reflected beam polarized at 90 deg. to the incident beam. This reflected beam passes through the lenses and prism to reach a screen having stationary stripes spaced like those produced by the drum. The transversely moving striped pattern of the reflected beam produces alternate peaks and troughs in the intensity of the light transmitted by the lens to light--sensitive detector, whose output is analysed by a computer.

Title: Fraud-proof plate seal or disc - has printed plastic foil divided into individual areas
IPC: G09F3/00
Filed: 1974-06-20
Abstract: The plate seal or disc ensured against counterfeit is designed especially for vehicles. The carrier layer (6) forming a carrier foil and made especially of paper is extended beyond the contour of the disc by a tongue (8). This tongue is made in the same way as the rest of the disc, hence it contains foil (1), protective layer (4) and carrier layer. Between the disc and the tongue the protective layer and foil are broken, especially notched. A layer (10) mixed with a binding agent and made especially of aluminium powder can be applied to the foil. This layer is divided into individual areas and has the carrier layer on its top side.

Title: High energy ions detector is insulating sheet between conductors - with insulating effect temporaily broken by impacting ion
Inventor: SCHMIDT HUGO DIPL PHYS DR
IPC: H01J47/00
Filed: 1974-06-24
Abstract: A detector for high-energy ions in a gas filled chamber or vacuum comprises an extremely thin electrically insulating plastics sheet coated on both sides with an electrically conducting coating, at least one of these coatings being extremely thin; each of these coatings is connected to one pole of a direct current source (13), with a current meter in the circuit. The plastics sheet is pref. about 0.1 micron thick, and is esp. of collodium or formvar, the electrically conducting coatings (3, 7) being pref. 0.05-0.08 micron thick and of aluminium. The entire composite sheet may either be mounted upon a surrounding frame, or upon a supporting metal plate. The detector is used as a substitute for solid state counting devices, where the semi-conductor material is very expensive. The new arrangement is much more economic and in addition hardly retards the ions which strike it, so that their energy is reduced by only a small amount. The plastics sheet may be made by floating off a coating prepared on a glass plate onto a water surface, then stretching it onto a frame; after this, the aluminium coatings may be vapour deposited on both sides.

Title: Rotation governor for drive shaft of shutter door - has shaft bearings displacing centrifugally to engage tapered recess
Inventor: WIEFELS WILLI
IPC: E06B9/84
Filed: 1974-12-11
Abstract: The governor obviates slippage due to shaft torsion inherent in ratchet type mechanisms and controls the rate of shutter descent. Cylindrical shaft bearings (3) displace radially under centrifugal force to engage a tapered recess (11) in the shaft housing (9), the displacement taking place at a specific rotational velocity and preventing further velocity increase. The bearings align in radial slots (2) fashioned in a shaft borne cage (1), each slot step reducing (15) in depth at the slot trailing edge. The shaft housing, generally confining the cage, enlarges (11) in internal dia. over a segment to form a stop recess for displaced bearings, this recess having a gent tapered (12) leading wall.

Title: Pretzel strand shaping machine - with stacked belt conveyors and curved facing plates rolling dough in alternate directions
Inventor: KUMMER ALFRED
IPC: A21C3/06
Filed: 1975-01-18
Abstract: A pretzel strand shaping machine produces parallel pieces of dough with a thick middle portion and greatly reduced ends which can be slung by hand into the pretzel form. A set of five horizontal belt conveyors, arranged on top of each other, produces the pretzel strands in conjunction with stationary guide plates of successively changing shape by rolling them in alternate directions in an ascending sequence. The final strands are discharged where their internal stresses are zero. The strands are discharged parallel to each other to facilitate the subsequent manual handling. The machine is simple in design, inexpensive and takes up a minimum of space in a bakery. Excellent pretzels of up to 20 mm dia. in the middle and 5 mm dia. at the ends are produced by it.

Title: Light emitting diode supply circuit - produces alternating voltage whose peak value exceeds inverse voltage of light emitting diode
IPC: H05B44/00
Filed: 1975-02-13
Abstract: The supply system applies an alternating voltage to the light emitting diode (11) through a series impedance (14). This sereis impedance is of such value that a forward current of sufficient intensity for the diode luminescence flows through it. When an inverse voltage is applied the light emitting diode breaks down, but the current and heat dissipation are limited to safe values. The apparatus may be used in fault alarm systems is controlled by a switch (18). When the light emitting diode is in operation, the radiation is detected by a photocell (22) which operates an alarm signal.

Title: Digital exposure control with simplified resetting circuit - sending pulses simultaneously to counter frequency divider and AND circuit
Inventor: NUMATA SABURO
IPC: G03B7/093
Filed: 1976-05-07
Abstract: Depressing the shutter-release knob brings into operation the light-measuring circuit and a pulse generator whose pulses are frequency-divided to correspond with the aperture setting and film speed. The frequency-divided pulses are counted, the result converted to analogue form and compared with the measured brightness. When equality is found, the counting stops, and the absence of a 1 at the input to an OR circuit energises the shutter-hold-open magnet. The reset circuit now sends pulses simultaneously to the counter, frequency divider and the AND circuit that opens the shutter, when it receives a pulse from the frequency divider.
