Title: Apparatus for applying reinforcing slips provided with a glue coating to a web having transverse perforation lines
Inventor: MUNDUS FRIEDHELM
IPC: B31B50/86
Filed: 1990-02-19
Granted: 1995-06-06
Abstract: An apparatus is disclosed which serves to apply reinforcing slips provided with a glue coating to a web which has transverse perforation lines, preferably to a web that consists of bags, which are joined at the trans-verse perforation lines, comprising means for tearing from the web the sections or bags which are joined at the transverse perforation lines. A belt conveyor is provided, which consists of spaced apart endless conveyor belts, which are trained around receiving-end belt pulleys. A conveyor roller is disposed above said receiving-end reversing pulleys and urges the incoming web against the reversing pulleys. The conveying belts of the upper course are supported by a supporting roller, which is spaced behind the receiving-end reversing pulleys by a distance which is smaller than the spacing of the transverse perforation lines of the web. The supporting roller constitutes a backing roller for cooperating with a rotating segment, which has a cylindrical peripheral surface and serves to hold and transport the reinforcing slips. The radius and the surface speed of the peripheral surface of said segment are so selected in dependence on the length of the sections of the web that said segment urges each section of the web against the backing roller and causes a portion of each section of the web to be in rolling contact with the backing roller between two conveying belts. The surface speed of the segment and of the backing roller exceeds the conveying speed of the belt conveyor so that a slip is stuck on each section and each section is torn from the web.

Filed: 1990-04-27
Granted: 1999-11-02
Abstract: In the transmission of digital video data signals, for example, in a digital video tape recorder, a luminance signal and first and second chrominance signals, such as R-Y and B-Y, are individually sampled to provide respective digital luminance data signals and first and second digital chrominance data signals for forming a high-definition video picture. Time code data signals representing the corresponding frame including the sampled signals are provided as individual sets of identical signals.      The digital luminance data signals and the first and second digital chrominance data signals are divided into respective sets thereof which each consist of two successive data signals. The sets of time code data signals, digital luminance and first and second digital chrominance data signals are distributed into a plurality of transmission channels in such a manner that each set of digital luminance data signals is interleaved between sets of the first and second digital chrominance data signals, respectively, in each of the transmission channels and that each of the sets of time code data signals is likewise distributed into each of the channels. Further, one of the two successive data signals in each of the sets of digital luminance data signals, first and second digital chrominance data signals and time code data signals is inverted for obtaining the complement of the one of the two successive data signals in each set which has been inverted, thereby substantially minimizing any DC or low-frequency component in each of the transmission channels.

Title: Feature board with automatic adjustment to slot position
Inventor: MCNEILL ANDREW B
IPC: H01R9/00
Filed: 1990-06-01
Granted: 1993-08-24
Abstract: ABSTRACT      A plug-in feature board for  a  computer  system has special circuitry to permit the board to customize itself to the particular slot into which it is inserted.  Computers of the  type  intended  for  individual  use  or use  in  small networks  typically  provide  insertion  slots  including connectors  to  permit  feature  boards  to  be  added and connected to a bus of the computer for adding new function or capacity.  As the computing power of such systems has increased there have been increases in the size of portions of  the  connecting  bus  to  permit  improvements  in  data transfer performance.  In a given computer system there are often two or more bus connector configurations presented in respective slots.   By so converting electrical states at selected   connector   positions   as   to   provide   signal information for determining bus configuration for the slot, special logic provided on the board is enabled to determine the characteristics of the slot in which the board is placed and customizes the board to respond or limit response in accordance with the requirements for that configuration.  By so  adapting  to  the  slot  the  board  achieves  enhanced applicability   and   avoids   certain  system   disabling malfunctions which can occur when a board is plugged into a slot for which it is not configured.

Granted: 1999-01-05
Abstract: A device for dispensing flexible sheet material, such as paper toweling, from a roll has a feed mechanism including a crank- or lever-operated roller having a drive section and a pressure element engageable with toweling extending around a portion of the roller.  The pressure element is spring-biased toward the outer surface of the roller drive section and provides sufficient friction between the roller drive section and the toweling to cause it to be unwound from a roll and advanced for dispensing with out the need for an idler roller which can cause jamming.  In one embodiment, a transfer assembly is provided for sequentially dispensing toweling from a primary roll and a reserve roll, after all the toweling has been dispensed from the primary roll.  The transfer assembly is mounted for movement between a non-transfer position, where a sensing arm is biased into engagement with the outer surface of toweling on the primary roll to effectively sense the thickness of both the toweling on and the roll core of the primary roll and a pair of transfer legs on a transfer arm are spaced outwardly from the outer surface of the roller, and a transfer position, where the sensing arm engages the outer surface of the primary roll core and the transfer legs push toweling from the reserve roll against the outer surface of the roller and cause it to be fed between the dispensing surface of the pressure element and the roller drive section.

Title: Method and plant for measuring the solid volume of a load, such as a load of timber
Inventor: LINDBERG EBBE
IPC: G01F22/02
Filed: 1991-05-16
Granted: 2001-10-30
Abstract: A method for measuring the solid volume of a load of timber comprises the steps of introducing the load into a compartment which is hermetically sealable against the ambient atmosphere and located in a housing into which is gradually introduced a fill-out means intended to reduce the volume, and thus increase the pressure, of the gas in said compartment; determining, after at least a certain excess pressure has been established in said compartment, the product of gas volume and gas pressure as a first reference value; and measuring the solid volume of the load as the difference between said first reference value and a second reference value of the product of gas volume and gas pressure, determined under identical conditions, but with no load in said compartment. The load is introduced into the housing on a goods vehicle, more precisely through a hermetically sealable gate of the housing, and is left on said vehicle while the first reference value is being determined, whereupon the vehicle is removed from the housing through a hermetically sealable gate.

Title: Device for transferring individual sheets to the impression cylinder of a sheet-fed rotary printing machine
Inventor: GERMANN ALBRECHT JOSEF
IPC: B41F21/00
Filed: 1991-07-19
Granted: 2000-11-14
Abstract: The device has a transfer cylinder (2) with a drum (4) which is adjustable in the circumferential direction relative to its shaft (3) and which carries sheet grippers (8) with a front stop (8a) for the sheets (B). The diameter of the transfer drum (2) is equal to 1/N of the diameter of the plate cylinder which carries N printing plates. The shaft (3) of the transfer cylinder (2) rotates at a constant speed and executes N revolutions when the plate cylinder is executing one revolution. By means of a controllable setting device, the drum (4) is so displaced relative to the shaft (3) during each revolution that the front stop (8a), when its transfer position in which a sheet is transferred to the impression cylinder (D) is passed, assumes a position by which the exact register of this sheet in relation to the position of the printing plate printing it on the plate cylinder is set. This guarantees that the width of the front margin between the sheet front edge and print start is of the same size on all the printed sheets, without the need to adjust the printing plates exactly on the plate cylinder in a time-consuming way.
