Title: Pneumatic postal tube system - has carrier load measuring unit with microswitch to regulate driving air speed
Inventor: SCHRECK KURT
IPC: B65G51/16
Filed: 1977-03-17
Abstract: The pneumatic dispatch tube installation for transporting light and heavy carriers has in each tube line at least one holding unit with a load measuring unit whose output controls the air supply system. The heavier carriers are subjected to a higher air speed. The load meter comprises a microswitch (MS) embedded in the holding unit and encircled by a steel spring (SF) over which an elastic plate (AP) is placed. The plate is depressed by the head (BK) of a carrier and if the carrier is sufficiently heavy the microswitch is activated to regulate the air supply accordingly.

Title: Magnetic tape recording and playback appts. - has rotating head wheel for tape guided over cylinder along helix
Inventor: ZAHN HEINRICH
IPC: G11B15/61
Filed: 1977-03-21
Abstract: In the region of the recording and/or playback unit where the outer limiting face, rotating with a larger radius than the cylinder radius, of a magnetic head (6) secured to the head wheel (5) encounters the tape (1) wound round the cylinder (3) at the start of the scanning movement there are devices which lift the tape radially over the outer shell of the cylinder. They lift it so far that the direction of the starting tape is approximately a tangent to the arc described by the outer limiting face of the magnetic head. Where the tape scan ends the tape can be guided on the outer limiting face radius until the direction of the terminating tape is a tangent to the arc mentioned.

Title: Quadraphonic signal transmission system - produces four independent signals for reception by quadraphonic and four channel receivers
Inventor: JUHASZ GABOR
IPC: H04S3/02
Filed: 1977-03-28
Abstract: The quadraphonic signal transmission system has a coder to form four independent signals from the output of four microphones (or other signal sources). These signals are transmitted via a 2 or 4 channel path to a decoder. The signals can be received both by a quadraphonic receiver and by a receiver with four discrete channels. The four signals are formed according to: U=aLF+bRF, V=cLR+dRR, S=eLF+fRF, T=gLR+hRR, where a-h are real or imaginary constants. These signals are added to give X=U+V and Y=S+T.

Title: Moulding plastics articles with undercut grooves - by inserting deformable members in mould cavity and deforming members to groove dimensions prior to moulding
Inventor: MERGLER WALTER
IPC: B29C33/50
Filed: 1977-04-09
Abstract: Plastics articles are moulded with under-cut grooves by inserting, through the mould wall, the required number of inserts, each of which, prior to moulding of the article, has >=1 dimension smaller than the moulded grooves. The inserts are deformed (inflated) into a state in which they have the dimensions corresp. to the grooves for the purpose of moulding the grooves, and after moulding they are deformed to their original state for removal from the grooves and the mould. The process is for mounting fittings in the moulded articles, e.g. fan light fittings in window frames using epoxy resins.

Title: Fine chopped timber preparation plant for power station - has rotating drums with carbide cutters and sawdust is blown into furnace
Inventor: VOELSKOW PETER
IPC: B02C19/20
Filed: 1977-06-18
Abstract: The power generating plant uses wood and other natural growing plant material. The wood is finely chopped and dried. This wood is blown into the power plant from a metering bunker. The wood and natural material is utilised on large scale. The coarse chopping is carried out by a relatively slowly rotating drum (1) with carbide cutters. This drum is mounted on a chassis (2) and operates together with a timber cutting machine (3). The chopped material is floated or driven in a press container (4) to the thermal power station (10). After intermediate storage the material is dried further by pressing out of water. Flue gases are used for subsequent drying and material is stored. A fine chopping machine produces sawdust like granulate with another chopping drum (1). The fine material is burnt and the flue gas is cleaned by filters.

Title: Monochromator with linear wavelength scale - has diffraction grating rotating through angle of 20 degrees at uniform speed and connected to sine wave generator
Inventor: BRUINS HANS-JOACHIM
IPC: G01J3/18
Filed: 1977-06-22
Abstract: A grating monochromator has a rapidly rotating diffraction grating by means of which exactly reproducible spectra can be generated with a linear scale of wavelengths. The grating rotates through an angle of about 20 deg. with a uniform speed drive, and is connected to an electrical sine-wave generator which is used for the presentation of the linear scale spectrum. The sinusoidal generator may comprise a diaphragm system passing a light-beam over a photocell in such a ways as to generate a sinusoidal output current, or a mechanically driven sine potentiometer. The system avoids the errors inherent in a system in which the grating is given a sinusoidal drive, which may be subject to mechanical wear or inaccuracies, and have limitations in operating speeds.

Patent DE-2820692-A1 (DE)
Title: Sewage aeration system - with cylindrical element revolving on vertical shaft above bubble releasing ring
Inventor: MUSKAT JOSEF DR RER NAT
IPC: B01F27/94
Filed: 1978-05-11
Abstract: System is based on conducting ascending bubbles along a revolving vertical element which produces a thin laminar flow with a high radial velocity gradient. The laminar flow continue over the full height of the element. A revolving cylinder on a vertical shaft has a cone at the bottom which guides the air bubbles along its surface. Its top can be closed or open. The bubbles are produced in perforations of a ring to which compressed air is supplied through a pipe. The velocity gradient produces an inverse pressure gradient so that the bubbles adhere to the element as they rise to the surface. Their path is thereby lengthened and they are broken up into finer bubbles.

Title: Mine support shield hydraulic setting cylinder control - has pressure regulated valve hydraulically locking cylinder
Inventor: BECKMANN KLAUS PROF DR ING
IPC: E21D23/16
Filed: 1978-07-27
Abstract: The prop-supported cap is hinged to a fracture shield, with one or more hydraulic cylinders hinged in between, on the shield support frame used in underground mining. The control system for the setting cylinder is dependent on pit setting pressure, and incorporates a pressure-regulated control member which hydraulically locks the cylinder in the mineral-working position. This can comprise a hydraulically activated valve sited in a line linking the cylinder with the return, and with regulating piston connected to the prop pressure space or setting-pressure lead. This ensures that the frame takes up fracture shield loading without loss of stability, and that correct position is taken up, even with uneven roofs.
