Title: Arrangement for identifying the position of a movable body with ultrasound
Inventor: WUTTKE GERO
IPC: G01S15/87
Filed: 1987-06-30
Granted: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE            For identifying the position of a movable body comprising a reflector, a primary transducer and a secondary transducer are utilized which transmit ultrasonic pulses to the reflector and, in turn, detect the ultrasonic pulses reflected by the reflector.  A measuring device identifies a positional value assigned to the position of the reflector from the transit times of the ultrasonic pulses from both transducers. To this end, the measuring equipment has a primary control to which a calculator, a primary memory, a timer and a pilot control are coupled.  Furthermore, the measuring equipment has a receiver, a transmitter and a transfer device which alternately connects the ultrasonic transducers to the measuring equipment.

Title: Vacuum cleaner bag with oscillating tube
Inventor: GENOVESE VINCENT P
IPC: A47L9/14
Filed: 1987-09-28
Granted: 1992-10-06
Abstract: ABSTRACT      A  bag  is  shown  for  use  with  an  upright  vacuum cleaner of the type having a motor fan contained in a main housing for producing an air flow out an air duct of the housing.   The bag includes a flexible body having side  walls  formed  of  an  air  pervious  material which define a normally closed interior and a mouth opening. The mouth opening of the flexible body is secured to the air  duct of  the main housing  to produce an air  flow through the flexible body for exhaust to the atmosphere. An oscillator tube, formed of a flexible material, has an interior, an open end at one extent and an intake opening at the opposite extent.   The intake opening is arranged to communicate with the mouth opening of the bag body so that the air flow from the main housing passes through the  oscillator   tube   and   causes  oscillations,   the oscillations of the tube serving to vibrate the bag and prevent the  buildup of  dirt on  the bag interior  side walls.

Abstract: PHN 11.984                                                 09.04.1987 Abstract:          Multi-colour display unit comprising a control means for colour selection.     A multi-coloured display unit is described for characters having colour indicator signals. The characters can be displayed in a plurality of colours. Without information of the identify of the characters getting lost, the legibility structure is influenced by the spreading of the colours over the various parts of the text. Initially, such colours are preselected when compiling the text. However, for various implementations this spreading is sub-optimal. Consequently, a transforming device is comprised for realizing and implementing a different colour structure and hence improving the legibility structure depending on the application and the original structure of the colour.

Title: Printing machine cylinder with adjustable groove cover element
Inventor: FISCHER HERMANN
IPC: B41F27/12
Filed: 1988-02-18
Granted: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE.       To permit continuous adjustment of a groove cover element (15), the groove cover element is extended in the groove, formed with a through-bore (14) in which an eccentric cam (7) is located, which can be rotated by a spindle.  By rotating the spindle, the  cover element is raised from the groove, or lowered against a rubber blanket, printing plate or the like thereon.  The spindle can be locked in rotated position by a counter nut (Fig. 1) or can be free  to rock continuously during rotation of the cylinder by linking the spindle to an arm which rides  on a fixed cam.  The cam can be adjusted so that the position of the spindle, and hence of the groove cover element, will be flush with the cylinder just at the time when the cylinder rolls off against an adjacent cylinder (100).  Adjustment of the cam can be manual, for example via a worm gear drive, or electrically, for example by a stepping motor, so that automatic  speed-dependent positional adjustment of the cam is possible.

Abstract: ABSTRACT OF THE DISCLOSURE             Apparatus and methods for producing bows with conical ornamental elements from a roll of sheet material. The sheet material is conveyed through a rotary die which produces a continuous blank with pairs of opposing leaves. The blank is then conveyed between sets of cone-forming assemblies which transform the leaves into the required conical elements. The resulting strip with paired conical elements is advanced towards a rotary cutting element which separates bow components, each bow component having an elongate central part and a pair of opposing conical elements. Each bow component is pushed onto a pronged collecting element which is indexed about its longitudinal axis with each bow component collected. This produces a set of bow components extending radially in various directions. The set of bow components is then stripped from the collecting element and stapled onto a cardboard backing member.
