Patent DE-2457253-A1 (DE)
Inventor: KAULE WALTER DIPL ING
IPC: G01B11/24
Filed: 1974-12-04
Abstract: 1488536 Measuring deflection by optical interference KRAUTKRAMER GmbH 24 Nov 1975 [4 Dec 1974] 48172/75 Heading G1A Apparatus for sensing the deflection of a workpiece surface 5 resulting from accoustic energy applied thereto comprises laser 1 whose beam 9 after reflection from surface 5 is split by beamsplitter 2 into portions 9a, 9b which positionally coincideon sensor 7, portion 9b being delayed due to the distance 11. Surface 5 is subjected to accoustic energy at 1 to 10 Hz. The strength of the signal from photo-cell 7 depends on the phase difference of 9a to 9b, which varies according to the deflection of surface 9 during the delay time. For the phase difference over the photo-cell of diameter d to be constant, the angle between portions 9a and 9b at the photo-cells <#/2/d. For this the distance from surface 5 to splitter 2 is at least 5S for a diameter of 1 cm, or a telescope lens system with an aperture at the common focal point is interposed between 5 and 2 or mirror 10 and 2. The delay path may be folded by a pair of facing mirrors. Length S may be modualted Piezoelectrically at a frequency f 1  higher than the accoustic frequency f 2 , so that the optimum path period occurs several times within the vibration period and the photo-cell output is at frequency f 1  modulated by f 2 . The broken lines of Fig. 6 show the light beam of a second interferometer used to maintain a constant length S. If the distance of the delay path S via mirrors 2a, 18a, 18b and 2b alters, illumination at photo-cell 19 alters, giving a signal via amplifier 20 and filter 21 to Piezo-electric element 24a  causing the motion of mirrors 24b to restore the illumination of photo-cell 19. Alternatively S may be kept constant by the Piezo-electric means moving mirror 18 relative to a fixed reference.

Title: Remotely operated coupling jaw - with blocking lever to lift and secure blocking bolt
Inventor: CRAMER GEORG
IPC: B60D1/02
Filed: 1974-12-13
Abstract: The coupling jaw is fitted with a vertically moving locking bolt which is secured in its down position by a pivotted locking lever and by a laterally moving, spring loaded bolt. The locking lever presses down onto a hollow in the head of the vertical bolt, and has a second arm which presses the lateral bolt backwards when the arm is raised, by operating a Bowden cable linked to the dashboard. This raises the vertical bolt and opens the jaw. The jaw is closed again by releasing the cable, with a spring loaded indicator arm pressing the bolt down. The indicator arm enables the driver to see if the jaw is open or closed without leaving the cab. It also serves as a manual lever if required.

Title: Door operated automatic seat belt - with ratchet retainer released by door sensor between door and frame
Inventor: BUFLER ERNST DIPL ING
IPC: B60R22/06
Filed: 1975-03-15
Abstract: The automatic fitting safety belt has a fitting secured on the car door (1) on a sliding support (5c) so that when the door is closed the belt is drawn down the guide to a locked position at the bottom rear corner of the door. The slider (4) is operated by a cable drive which is wound around an upper reel, against spring pressure at the other end of the guide. The reel is operated by a second cable drive (8) linked to the door frame so that when the door is opened the reel is wound in to pull the slider up the guide. A ratchet prevents the slider from running back down the guide when the belt is released. The slider is held in the up position until the door is completely closed when a ratchet release shaft (15) engages the door frame to release the ratchet.

Title: Semiconductor wafer heat treatment furnace - has horizontal rods in furnace tube with helical grooves conveying wafers on edge
Inventor: GUECKEL HELMUT DIPL PHYS
IPC: B65G33/06
Filed: 1975-12-22
Abstract: Semiconductor wafers requiring heat treatment are conveyed through a horizontal furnace tube continuously, standing on edge and parallel to each other. Two rods, made of the same material as the wafers, run along the bottom of the tube. They have spiral grooves to accept the wafers and transport them through the furnace when revolved in the same direction. A very uniform temp. distribution is obtd. Mechanical stresses, induced by temp. gradients, are eliminated. The revolving wafers ensure an even contact with the reactant gas. The rate of feed can be freely selected by combining the pitch of the thread with the speed.

Title: Fodder mixer with controlled feeds from constituent hoppers - through slits with slide valves to give correct outlet shape
Inventor: HOFFMANN HANS
IPC: B01F25/90
Filed: 1976-03-30
Abstract: A fodder mixes comprises a number of cells each discharging through a hopper botom and a cell-wheel or similar extractor to a common conveyor; the conveyor removes the materials from all the cells. Each cell has a discharge opening in the shape of an elongated slit; the width of the split permits av.-sized conglomerate of the material to pass through, and the open length of the slit is defined by one or two slide valves adjustable along the length of the slit. The arrangement provides an outlet opening of generally square or circular shape, in contrast with the prior art crescent shape. It enables a much less selective flow of material to leave the hopper and prevents large conglomerates from being retained in the hopper.

(I) can be used directly, without further solvents. (I) may be used which can form highly crosslinked end polymers during reaction in aq. medium. Use of (I) contg. -NCO end-gps., reacting with water with CO2 dissociation, leads to light, expanded articles.

Title: Transmission vibration damping system for tractor - has profiled sealing gasket fitted between engine and gear box
Inventor: MEINCKE KLAUS
IPC: B60K5/00
Filed: 1976-06-18
Abstract: The engine block and transmission unit of the tractor are joined by special flanges with profiled sealing gaskets (11) clamped between them. The gaskets prevent the transmission of vibrations in either direction to reduce the vibrations on the driving seat, which is directly mounted on the transmission block. The sealing gaskets are profiled with axial and transverse sections to accommodate axial and transverse vibrations. They enable the block construction system to be used. Separate parts of the transmission are similarly isolated from each other.

Title: Flash evaporator for e.g. seawater or industrial effluent - has tapering duct to flash nozzles and diverging evaporator duct in each stage
Inventor: SAARI RISTO DIPL ING
IPC: C02F1/06
Filed: 1976-06-23
Abstract: A flash evaporator comprises a series of evaporator stages, each discharging through one or more flash nozzles into the next stage, the direction of discharge being transverse to the general flow direction. The evaporator comprises two sets of ducts, one set of lateral ducts tapers in its cross-section in the direction of flow towards the end of each evaporator stage, while the other duct or set of ducts increases in cross-section in the same direction. The water discharged from the first set of ducts through the flash nozzles into the second duct and at the downstream of the second duct, the water returns to the first duct of the next stage. A condenser receives and condenses the vapour from the second, diverging set of ducts. Used for any flash evapn. e.g. evapn. of sea water or industrial effluent, where the viscosity may be high. The arrangement ensures that a heavy thick layer of water does not discharge over the weir or nozzle into the evapn. duct, but that a sufficient area is exposed to evapn. to achieve improved thermal efficiency.

Title: Optical angular position indicator - senses light reflection from sector shaped marking around circumference
Inventor: CLARK MALCOM D
IPC: G01D5/26
Filed: 1976-10-15
Abstract: The positional sensor is especially for a rotating element with a reflecting programme surface (16) extending round the circumference and with a decreasing width so that the width at a given distance from the start of the surface is a measure of angular rotation. Light is projected on to this sector and reflected light is received by a detector according to the position of the revolving shaft whose intensity depends on the width of the programme surface, and hence on the angular setting. The detector may activate a servo-control for setting to a predetermined position.
