Patent DE-2405559-A1 (DE)
Title: Adjustment means for height of bed - allows bed end to move straight back into horizontal position without prior forward movement
Inventor: PETRI HEINRICH
IPC: A47C20/04
Filed: 1974-02-06
Abstract: Two supports are movably connected to the adjustable parts and at their lower ends engage in grooves of a track on corresponding guide elements which in addition are each provided with a further deeper track set at the side of the first track. The locking pin by means of which the support engages in the grooves passes through a bore of a free moving tilt member which is in the form of a parallelogram and slides on the deeper track. The distance between the bore and the lower face of the tilt member corresponds at least to the distance between the two tracks of hte guide element whilst the distance of the bore from the inclined side face of the tilt member is less than that between the two tracks. The top of bottom of the frame can thus be moved back directly into the horizontal position without first having to raise it forward to its highest position.

Title: Wheel spinning attachment for aircraft tyres - has integrally vulcanised wind catching blades on tyre walls or wheel disc
Inventor: HEINRICH MARTIN
IPC: B64C25/40
Filed: 1974-02-14
Abstract: The aircraft tyres have blades which cause the wheel to spin in the air stream when the wheels are lowered before landing. The rotating speed of the wheels is such that the wheel peripheral speed and the landing speed are approximately equal, which reduced the high wear of tyres subject to enormous loads when the stationary wheels meet the ground. A tyre is provided with vulcanised pockets on either side. The blades can be directly vulcanised after completion of the tyre on the tyre side wall or they can be moulded into the tyre during the production process. These pockets can also be moulded into the tyre tread part in which case the tread part is additionally thickened. Alternatively the blades can be also made from aluminium or another light alloy as an integral part of the wheel disc.

Title: Ultrasonic delay line production method - delay has propagation element with plane surface with input and output transducers
Inventor: KRUEGER HANS-JOACHIM
IPC: H03H9/36
Filed: 1974-02-16
Abstract: At first one single transducer element is applied to the surface, whose size is greater than that of the required input and output transducers together. Then this element is cut by a material removing tool into the input and output transducer. The cutting is so deep, that part of the substrate is also removed, leaving a groove whose width is equal to the spacing in time between the two transducers. The manufacturing process is simplified since only a single soldering stage is necessary to produce the transducers. Differences of conducting qualities of the transducers caused by material scatter is greatly reduced. The distancing between input and output transducers can be very accurately placed.

Title: Controller for machine elements dependent upon element position - incorporates two buffer surfaces, one with fluid switch
IPC: B23Q15/22
Filed: 1974-02-20
Abstract: The invention relates to a control arrangement for a movable machine element whereby a buffer surface on the element operates in conjunction with a surface of a fixed buffer to generate a signal. The buffer surfaces lie across the direction of movement of the element, pref. at right angles. The fixed buffer incorporates a control channel which opens towards the moving element and may carry an air nozzle which operates a fluid switch by pressure build up when closed by the buffer surface of the element. In an embodiment of the invention a transducer is connected to the pneumatic switch to generate an electrical signal which is then amplified to operate the control arrangement.
Patent DE-2413834-A1 (DE)
Title: Ceiling drill chip attachment - consists of semi-spherical elastically yielding transparent receptacle to catch chips
Inventor: HEINZEL GOTTHARD
IPC: B23Q11/00
Filed: 1974-03-22
Abstract: Chips dropping from the bore hole when drilling ceilings can be detrimental to safety. Attachment hitherto used, such as a piece of cardboard fixed to the chuck and rotating with it are unsatisfactory, as they tend to eject the chips in every direction due to centrifugal force. The present arrangement envisages a semi-spherical stationary catching device attached to the drill body by means of a cranked leg with an opening large enough to let the drill bit rotate freely. The receptacle is open at the plane end with reinforced rims to ensure positive sealing against the surface to be drilled. As the drill bit advances into the material, the semi-spherical receptacle deforms accordingly.

Title: Yarn dyeing testing process - uses connecting chamber for probe to pass through and bring back cut sample
Inventor: STUMPP ROLF
IPC: D06B23/12
Filed: 1974-05-03
Abstract: In process for the extn. of a yarn sample, from yarns being processed in a pressurised dyeing vessel passing round continuously at over 100 degrees C, the passage of the yarn round the interior of the chamber is stopped, and blanking disc is displaced to connect a chamber to the vessel. A shaft passing through a hollow tube inserts an extractor into the vessel for a length of yarn to be caught between two plates and cut, to be withdrawn into the chamber for removal when the disc has been replaced. The system allows tests to be made on the yarn during the dyeing process, in a short space of time, and without affecting the dyeing conditions or wasting the energy used in maintaining the dyeing vessel at the required temp. and pressure.

Title: Clothes drier with horizontal-axis rotary perforated drum - preventing air from circulating around drum, without causing creases
Inventor: GESCHKA HUGO WERNER
IPC: D06F34/26
Filed: 1974-06-18
Abstract: Automatic clothes drier comprises a horizontal-axis rotary perforated drum surrounded at a distance by a stationary casing, and a condenser for removing humidity from the drying air. To obtain a dual air current in the drum, two fans are mounted in the upper part of the casing with their air currents directed onto the drum so that their point of intersection lies within the drum. Between the drum and casing are two opposed intermediate walls which are open at the bottom end and lead to the fan at the top end, to obtain two separate air shafts. In the upper third of each air shaft is a sprinkler pipe for cooling water, so that two separate cooling water streams are effective in removing humidity from the drying air.

Title: Control of supply of electrical power to consumer - has input terminals for connection to A.C. source and output terminals for connection to consumer
IPC: G05F1/455
Filed: 1974-09-25
Abstract: The bidirectional current controller has a control electrode. Two signal generators produce two signals representing the rated and actual values of the command variable. A tripping pulse generator sends tripping pulses to the control electrode, which are derived from the difference between the signal values, so taht when the difference exceeds zero the tripping pulses make the current controller conduct in both directions, when the difference exceeds zero by a smaller amount they make it conduct in one direction only and when the difference is zero the current controller is made non-conductive.

Patent DE-2538325-A1 (DE)
Inventor: BALLAMY WILLIAM CHARLES
IPC: H01L21/764
Filed: 1975-08-28
Abstract: Described is a molecular beam technique for fabricating semiconductor devices from Group III(a)-V(a) compounds. To form planar isolated devices, an amorphous insulative layer is formed on selected portions of a monocrystalline substrate of the Group III(a)-V(a) material which is at least semi-insulating. The amorphous layer may be formed by deposition of an oxide (e.g., SiO2), anodization of an oxide (e.g., native oxides) or by conversion of a surface layer of the substrate (e.g., by grit blasting). When a molecular beam containing Group III(a) and Group V(a) elements is directed at the surface, which is preheated to a temperature in the range of 450 DEG  to 675 DEG  C, monocrystalline Group III(a)-V(a) material grows on the exposed substrate whereas polycrystalline Group III(a)-V(a) material is simultaneously formed on the amorphous layer. The polycrystalline and monocrystalline surfaces are substantially coplanar. The polycrystalline material has a resistivity high enough to provide electrical isolation between active devices formed in the monocrystalline material. Examples of such active devices, which are also described, include beam-leaded Schottky barrier mixer diodes which have reduced parasitic capacitance and sealed-junction Schottky barrier IMPATT diodes. To form devices in which isolation is not required, the same procedure is followed except that neither the amorphous layer nor the substrate need be made of high resistivity material.

Title: Frequency modulated data transmission - involves method for evaluation of suitability of translations for data transmission
Inventor: KEMPER JUERGEN DIPL ING
IPC: H04L1/20
Filed: 1975-08-28
Abstract: A text generator at the transmitting end controls a device which converts binary data into an f.m. signal, sent through the translations to be tested. At the receiving end they are passed through an amplifier limiter and demodulated. The text generator controls the modular on the transmitter, and a detector is provided at the receiving end before the amplifier-limiter. It delivers a voltage proportional to the envelope of the f.m. signal. A clock pulse generator delivers clock pulses spaced by the duration of the text generator signal elemement. A detector output signal is scanned by these pulses, so that a first scanned signal is produced. A second scanned signal is produced by scanning the demodulated data signal.
