Inventor: GUTMANN GOTTFRIED BRUNO DR MED
IPC: A61B6/08
Filed: 1978-07-31
Abstract: The method for making an X-ray examination of the whole of a patient's spine, compensates for any sideways curvature of the spine. The cassette holder which is mounted in front of the patient, is marked with a vertical line corresponding with the axis of symmetry of the patient. Mounted on the cassette holder is an inverted U-shaped frame (4) with its sides (5) clamped at a required height in side gides by screws. One the cross piece is mounted a slider (8) with a transparent strip suspended from it, with a hair line down it. On top of the slider are two arms (11) with a pivot pin (13) across them for a positioning rod (14) with a knob (16) one end and a soft indicator point (17) at the other end. The rod can be swung up and down and is used for alignment as the camera and cassette are moved downwards.

Title: Engine fuel injection system - having internal contact surfaces lined with fluid repellent plastic
Inventor: HOEPPEL RAINER
IPC: F02M33/04
Filed: 1978-08-16
Abstract: In a fuel injection system for IC engines, all surfaces which come into contact with the air/fuel mixt. are coated by a material such as ceramics or plastics. The preferred plastic material is PTFE. This is resistant to any attack by the fuel/air mixt. and ensures a faster and more uniform mixt. transport. The uniform distribution of the mixt. improves the output of the engine and reduces the amt. of toxic components in the engine exhaust gases.

Title: Curtain rail with reinforcement cavity - has filling of foamed plastics and reinforcement chips of wood or plastics
Inventor: MOELLER HUBERT
IPC: A47H1/04
Filed: 1978-08-29
Abstract: The reinforcement substance (4) fills the cavity extending through the length of the curtain rail and consists of a mixture of foamed plastics and small chips of non-foamed material, these chips pref. having a dia. of about 0.5 cm and a length of 6-6 mm. The chips can be made of wood, plastics or thermo-plastics whilst the foamed plastics material is pref. PVC mixtures. This composition (4) provides an exceptional reinforcement so that just one cavity (3a) need be filled in the rail. The mixture which can be prepared by mixing in the chips with the prepared plastics foam can be readily injected into the cavity.

Title: Liquefied gas tank safety valve - includes fusible plugs for blowoff in case of fire
Inventor: KOBER DRAGUTIN DIPL ING
IPC: F17C13/12
Filed: 1978-09-15
Abstract: The parent patent described a safety device for liquefied gas tanks, espe. for tankers, with a blow-off valve which is pressurised at one side by the tank pressure and on the other side by a pilot pressure so that a pressure rise in a tank above a set threshold operates the blow-off valve. Fusible plugs have now been added to the system so that any temperature rise causes the blow-off valve to respond even at lower tank pressures. This is a simple and effective way by which the safety regulations can be satisfied in case of a fire aboard.
Patent DE-2842326-A1 (DE)
Title: Pressure pulse metering pipette - having liquid reservoir with overflow to measuring tube which discharges fixed volume through restriction when pressure is applied
Inventor: FAEHNRICH VLADIMIR DIPL ING
IPC: B01L99/00
Filed: 1978-09-28
Abstract: Channel type pipette is for metering small quantities of liquid by a directly acting pneumatic impulse. The measuring tube is filled with liquid from a reservoir via an overflow line. A fixed pressure is then applied which corresponds to a change in level in the measurement tube. The measurement tube has a narrow outlet tube leading to U tube with an overflow on the other side. The liquid is dispensed by subjecting the measurement tube to the pressure change which causes the liquid to be displaced. For a constant pressure, a constant liquid amount is dispensed each time. Allows reproducible accuracies to be achieved which are much greater than with other devices of this type.

Title: Solenoid using short path measuring device - has moving core coil current sensing threshold switch driving flip=flop
Inventor: HOLZAPFEL JUERGEN
IPC: G01G7/04
Filed: 1979-02-16
Abstract: The apparatus converts different positions of an axle into electrical pulses varying proportionally with the axle position, mainly for weighing applications, using a moving core coil mechanism. Two coils and two cores are used with the cores having a fixed connection. The cores are placed in the magnetic field so that when one inductivity is increasing the other is decreasing. Diodes and zener diodes are used to short circuit the coil current after it has been switched off by transistion. The current rising via the different or equal inductances is used to switch a flip-flop via a threshold switch. The force applied by the measured weight is converted into a movement distance by a conventional mechanism and used to displace the cores.

Title: Drawer with self-closing contact wall covering top - has spring biased contact elements ensuring wall closes open area of drawer for dust exclusion
Inventor: ZIMMERMANN GOTTFRIED
IPC: A47B88/00
Filed: 1979-07-16
Abstract: To keep out dirt, insects etc. when the drawer is closed, the drawer is covered at the top by a contact wall. To avoid using extra force to raise a heavily laden drawer up against this contact wall, the contact wall is arranged to rise and fall. This is achieved by contact elements set between the contact wall and the drawer preferably in the former of rollers (5) which when the drawer is closed fit into recesses (6) in the contact wall (3). As the drawer is pushed in the rollers hold the drawer and contact wall at a distance from each other so that the sealing faces do not rub against each other. With the rollers in the recesses, the contact wall rests under the pressure of springs (4) on the top of the drawer frame.

Title: Heat exchanger precipitator device - has horizontal separating chamber axis with sliding particle-collecting chamber underneath
Inventor: SUZUKI TAKESHI
IPC: B01D45/12
Filed: 1979-08-31
Abstract: The separating chamber (1) of the precipitator has a cylindrical shape and a tapered solid particle-collecting chamber (2) is provided adjacent to the separating chamber. The cylindrical separating chamber has a horizontal axis (C). The face of the cylinder is connected to an inlet tube (3) entering the chamber tangentially, while the centre of the cylinder face connects to exhaust tube (5) with axis identical with axis (C). During the operation gas laden with solid particles flows at high velocity through tube (3) into the separating chamber. Within the chamber the flow is converted into a gyratory movement, travelling along the cylindrical surface of the chamber (1) in direction (F) and then along a gyratory path (G) towards the other end of the cylinder. The solid particles are separated from the gas flow by centrifugal force and drop downwards into the collecting chamber (2) while the gas flow relieved of the solid particle content leaves the precipitator via a tube (5).

Title: Liquid nitrogen prodn. process - feeds liquid oxygen into base of low pressure column for air decomposition
Inventor: BAUMGAERTNER KLAUS DIPL ING
IPC: F25J3/04
Filed: 1980-04-28
Abstract: The process produces liquid nitrogen using the refrigerating action resulting from evaporation of liquid oxygen. The liquid oxygen is fed externally into the base of a low pressure column of a two-column unit, for air decomposition, where it evaporates in a main condenser under the action of the condensing nitrogen in a medium-pressure column. The nitrogen is collected below the main condenser, and drawn off as the product. The gaseous nitrogen can be drawn off from the head of the medium-pressure column, expanded to produce output, and brought into heat-exchange contact with the air to be decomposed.
