Title: Apparatus for repairing accidented bodies in motor vehicles
Inventor: TOMELLERI RAFFAELE
IPC: B21D1/14
Filed: 1989-11-29
Abstract: A B S T R A C T           The apparatus comprises a horizontally-extending base (2) mounted on wheels (3) and provided at one end (4) with anchoring means (5) locking it to a repair bench (6) and at the opposite end  (9) with a pair of double-acting hydraulic jacks (11, 12) hinged thereto and joined together at a junction point (P) which is raised relative to the base (2).  Connected to the junction point (P) is a third double-acting hydraulic jack (16, 33) which is intended to carry out a pulling or thrust action in order to straighten the deformed part (21) of the accidented body.  The junction point (P) defined by the intersection of the pair of jacks (11, 12) hinged to the second base end (9), can be shifted in space without discontinuity and can therefore take any appropriate position for a correct and quick straightening of the deformed body.

Title: Methods and apparatus for obtaining arterial blood samples
Inventor: LINEBACK PAUL I
IPC: A61B5/153
Filed: 1990-03-07
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus  and  methods  for  simultaneously  obtaining clinical  laboratory  and  arterial  blood  gas  samples  are disclosed.   The apparatus includes a flow-through plunger configured  for  being detachably secured  to  the tip of a standard  arterial  blood  gas  syringe.    The  flow-through plunger  has  a  conduit  through  the  center thereof  which permits blood to flow through the plunger into the arterial blood gas syringe.  The flow-through plunger preferably has a diameter larger than the diameter of the arterial blood gas syringe.   In this way,  the combination of flow-through plunger and arterial blood gas syringe function as a plunger assembly  for  a  larger  syringe,  preferably  a  clinical laboratory blood sample syringe.    Both a clinical laboratory blood sample and an arterial blood gas sample may be obtained by introducing arterial blood  into  the  clinical  laboratory  syringe  barrel  and passing the blood through the flow-through plunger into the arterial  blood  gas  syringe.     Arterial  blood  may  be introduced  into  the  clinical  laboratory  syringe  through either a direct hypodermic needle puncture into an artery or by  coupling  the  laboratory  syringe barrel  to an  ex-vivo arterial blood source.

Title: Chimneys for air rings used in the production of blown extruded plastic film
Inventor: PLANETA MIREK
IPC: B29C49/64
Filed: 1990-03-09
Abstract: ABSTRACT OF THE DISCLOSURE        A chimney member that is used with an air ring employed to cool a blown extruded tube of molten plastic material, and also to stabilise the moving tube, surrounds the tube as it emerges from the die to keep the cooling air in contact with the tube wall.  Too high air velocity results in instability of the bubble, resulting in non-uniform film, or even disruption of the bubble; the air volume and velocity must therefore be restricted.  The side wall of the chimney member is of inverted frusto-conical shape diverging outwards in the direction of bubble movement and spaced a minimum distance from the tube outer wall.  In one embodiment it is provided over substantially its entire area, preferably except for a narrow portion at its downstream edge, with a large plurality of uniformly distributed longitudinally and circumferentially spaced apertures, which permit the air in the passage between the chimney and tube to escape and reduce the venturi force it produces to a safe value.  In another embodiment the apertures take the form of longitudinally-spaced annular circumferential slots formed between annular wall portions and in a further embodiment they take the form of circumferentially spaced longitudinally extending slots.  The air velocity and volume can now be increased substantially without producing vibration, so that output is increased.

Abstract: Digital signal recording and reproducing apparatus for recording digital signals in successive tracks of given pitch on a record medium and for reproducing digital signals therefrom. A rotary head assembly including two pairs of head subassemblies angularly separated by approximately 180°, with each subassembly comprised of a pair of heads displaced from each other in a direction parallel to the track pitch, is driven at a predetermined rotation speed to record digital signals selectively supplied at respectively different original transmission rates which exhibit a predetermined ratio. The digital signals are timebase modified to have substantially the same data rate even though their original transmission rates differ from each other; and are coupled to the rotary head assembly. The record medium is driven during a recording mode at respectively different speeds determined by the original transmission rate of the selectively supplied digital signal, whereby the number of tracks recorded on the record medium during a unit time period T (where T is the time for the rotary head assembly to make a predetermined number of rotations) corresponds to the original transmission rate. The record medium is driven during a reproducing mode at the same speed as was used during recording, whereby during the time period T the rotary head assembly reproduces digital signals from twice the number of tracks that had been recorded during that same time period T.      The reproduced digital signals axe recovered substantially without defects at their original transmission rate by way of a memory.
