Title: Laboratory membrane filter - with membrane hose over annulus between cylindrical end pieces
Inventor: WALCH AXEL DR
IPC: B01D61/28
Filed: 1977-11-30
Abstract: A membrane filter, for use in the blood dialysis on a laboratory scale, consists of two cylindrical parts which are joined by a central rod. The annulus, created thereby, is covered by a membrane. Bores in the central rod lead to tail pieces for the fluid to be filtered. This is not a throwaway filter like the collodion sleeves, and can be used repeatedly. The annulus can be adjusted to vary the volume of the fluid to be filtered. Typically the cylindrical end parts are joined by a central rod either solidly, or adjustably by sliding one of the parts on the rod with O-rings. A membrane hose may cover the annulus secured by O-rings.

Title: Sewing machine fabric edge guide - has air jets to give braking action to manipulated fine fabrics without distortion
Inventor: KLEINSCHMIDT JOHANN OTTO DIPL
IPC: D05B35/10
Filed: 1977-12-27
Abstract: Thefabric edge guide mechanism for a sewing machine has jets in the braking zone between two plates. They provide an air stream to brake the fabric by pressing it against one of the two plates on either side of the material. The jets deliver an air flow which presses against the fabric, so that it is held against a plate opposite the jets. There are sensors in the edge guide to control the pressure and/or the volume of air delivered by the jets. The system ensures that the fabric is accurately positioned, allowing manipulation of very fine materials without distortion, so that the seaming is clean and fault-free.

Title: Roller skate with heel operated brake - has long wheelbase with rear wheels behind heel to ensure stability
Inventor: FUSS OTMAR
IPC: A63C17/02
Filed: 1978-01-09
Abstract: A roller skate (1) has two front wheels (2) and two rear wheels (2a). The front wheels are mounted on an arm (20) supported between two rubber pads (21) (23) from the front plate (19). An elastic plate in two sections (24) and (8) fastens the front plate (19) to the rear frame (6) which carries the rear wheels (2a). The rear wheels (2a) are arranged to lie beyond the heel support (5) in order to increase the stability of the skate. By pressure down on his heel the skater pushes down the button (14) attached to a lever on the spindle (15) which actuates the brake (10). This control of speed makes the skate safer for children to use but is also suitable for adults of any age.
Patent DE-2802019-A1 (DE)
Title: Signal generator marking TDC of IC engine piston - has projection on crankshaft which induces pulse in pick=up coil
Inventor: BLUM RUDOLF DIPL ING
IPC: F02P17/04
Filed: 1978-01-18
Abstract: The signal generator has a mark in the form of projection or a slot, rotating with the crankshaft, which induces in a d.c. carrying pick-up coil an a.c. signal with a positive and a negative half-wave. This signal is fed into an amplifier and pulse shaper, whose output signal is the signal marking the piston position, esp. t.d.c. A transformer (8) secondary windings (9, 11) are connected to a full-wave rectifier which delivers two d.c. pulses at each passage of the mark (3) before the pick-up coil (2). It is the input signal of an evaluation device which suppresses the first of the two pulses, and derives the marking signal from the leading flank of the second pulse.

Title: Rotating generator with superconducting shutter - moving between magnetic-field source and sensor coil to generate pulses
Inventor: SCHUR PAUL ELLIOT
IPC: H02K21/38
Filed: 1978-03-30
Abstract: The generator has its magnetic field generated by a device held by a first part of a holder. A sensor held by the second part of the holder responds to the magnetic field to produce an electrical signal proportional to changes in the field. A shutter moves across between the sensor and field-generating device to produce these changes in the magnetic field, thereby causing a signal to appear at the sensor's output. The sensor comprises a coil. The shutter is made of a superconducting material that is impermeable to the magnetic field in the region of absolute zero. The shutter is maintained at a temp. near absolute zero.

Title: contact-free measurement of surface tension and viscosity - propagates ultrasonic wave along surface using phase velocity and attenuation
Inventor: LIERKE ERNST-GUENTER DIPL PHYS
IPC: G01N13/02
Filed: 1978-08-24
Abstract: The contact-free measuring system determines the surface tension and the viscosity of a liquid or a smelt. It is achieved by generating surface waves on a specimen of the liq. to be measured. The amplitude of the waves is measured in order to determine the wave parameter. The surface tension is determined from the dispersion equation of the phase velocity of the wave. The viscosity is determined from the attenuation characteristics of the surface waves. The amplitude is determined by measuring the impedance.

Title: Sheet depositing system for printing press - uses air set to distort sheet into shape convex toward stack before setting down
Inventor: MOEBIUS KLAUS-DIETER DIPL ING
IPC: B65H29/04
Filed: 1978-08-29
Abstract: The system deposits sheets in the fly sheet deliverer of a printing press. On initial braking of the positively-guided sheets trailing edge, the sheet is subjected a linear air jet controlled by a timer, extending over its entire width and acting downwards on it. This distorts it at right angles to the travel direction into a shape convex towards the sheet stack. As the sheet nears the stack, it is released by the chain grips, and a further air jet, also acting from above but in the travel direction, moves in a line from the centre outwards. This distorts the sheet into a shape convex towards the stack but in the lengthwise direction, as it is set down on the latter.
