Abstract: The invention relates to a method and a device for the cutting of end disks for the packing of paper rolls. The invention is characterized in that the diameter of each roll is measured in a measuring unit (1) in a production line, that the number of disk blanks (2<sub>1</sub>, 2<sub>4</sub>2) needed for the packing of one paper roll are fed from one or several disk blank magazines (20, 200-203) and placed on and fixed against a cutting table (13, 221), rotatable about a center axis, said table being a part of a cutting unit (10, 205), that a knife (128) of a knife unit (9, 223) in said cutting unit is set at a radial distance from the turning centre of the cutting table which corresponds very closely to half of said measured diameter, by translational means (8) for this purpose and on the basis of the values measured by the measuring unit, that disks (21 b, 245) are cut from the blanks by rotating the cutting table in relation to the stationary knife, and that the cut disks and the annular excess material are removed from the cutting table sepa- ately.
Patent NO-177726-C (NO)
Inventor: MCGUIRE BRIAN EDWARD
IPC: B29C55/30
Filed: 1989-05-08
Abstract: The method uses a support (1) incorporating a pipe clamp (2) at one end and an electrically heated swaging die at the other. The liner pipe, external diameter larger than the bore of the pipe to be lined, is made of plastics or other suitable material and drawn at ambient temperature through the swaging die and threaded through the pipe to be lined. The diameter of the liner pipe is reduced to and/or maintained at less than the inner diameter of the pipe to be lined by the tension applied by the drawing force.The drawing restrains the radial expansion of the outer surface of the liner pipe as it emerges from the swaging die.

Title: Display system with graphics cursor
Inventor: HAIGH DAVID CHRISTOPHER
IPC: G09G5/00
Filed: 1990-07-24
Granted: 1995-10-10
Abstract: A display system has cursor definition memory for storing data defining a graphics cursor, a cache for the temporary storage of a portion of the graphics cursor for display on a display device, the cache being such that its data rate is sufficient to support the display of the graphics cursor, and control logic for updating the cache from the cursor definition memory at a slower data rate. The cache need only be large enough to store a portion of the cursor at any one time as the graphics cursor is only displayed for a fraction,  for example one-tenth,  of a scan line and the cache can be updated during the portion of  the  scan  time  when  the  cursor  is  not  displayed. Through the use of a small cache operable at the required data rate, inexpensive memory which does not support the required data rate can be used for the cursor definition memory.

Title: Mixing kneader
Inventor: KUNZ ALFRED
IPC: B01F7/04
Filed: 1990-10-03
Granted: 1994-11-01
Abstract: In a mixing kneader for the mechanical and/or thermal treatment of products, there is a shaft (16) arranged in a housing (1), on which shaft disk segments (21) are provided distributed in the axial direction. In the kneading spaces (24) between the disk segments (21) there are fixed kneading counter-elements (27), which clean the disk segments (21) and shaft (16) and comprise a section (30), running close to the disk segments (21), and an arm (31), running close to the circumferential surface (37) of the shaft (16) . In order that the section and the arm can give way to excessive production encrustations on the shaft, a center line (N) of the section (30) close to the disk segments (21)is to run at an inclination, in the direction of rotation (Z) of the shaft (16),corresponding to a secant through to a tangent with respect to the shaft (16). Something similar also applies to the center line (O) of the arm (31) and to a leg (28) adjoining the section (30) at the other end from the arm (31). This has theeffect that the formation of product bridges is also avoided and the product conveyance and mixing action are improved. In addition, the mechanical stressing of the kneading element and the taking up of torque by the shaft are reduced.

Title: Roofing material carrier
Inventor: OLEKSIUK PETER
IPC: B62B5/04
Filed: 1991-03-13
Granted: 1994-12-06
Abstract: This device is for supporting roofing material such as  shingles,  shakes  and  the  like, upon the roof deck to facilitate the installation thereof.  It consists of a planar support plate for a bundle of shingles or the like, ahead of the roofer and upon the usually upwardly sloping roof deck.   It is supported by two sets of castor wheels on the underside of the deck so that it can be moved readily and easily, upwardly, sideways or at any angle therebetween.  A pair of deck engaging grippers extend rearwardly and downwardly from the  front  or  lower  edge of the plate,  to prevent downward movement of the assembly.   When engaging the deck surface, these  are  endpointed  to engage the deck.   When adjacent a wall  or when the capping is being installed,  these may be replaced  alternate  grippers  with  rubber  pads  which  are pivoted to the end sharpened gripper which then engage the already laid roof material without damaging same.

Title: Apparatus for feeding fish processing machines
Inventor: DECHOW ULRICH
IPC: A22C25/08
Filed: 1991-03-26
Granted: 1996-11-19
Abstract: An apparatus for the timed feeding of fish into fish pro-cessing machines  serves to supply such fish into a con-veyor pushing them along in a direction transversal to their longitudinal axis and being provided with receiv-ing troughs or entrainers.  In order to be able to ob-tain the high performance non-mechanical feeding re-quired in view of the high yield of modern processing machines while restricting as much as possible the physi-cal stress on the staff responsible therefor, or to in-crease the non-mechanical performance without increasing the stress, a feeding apparatus is provided above the conveyor of the processing machine which apparatus in-cludes a rotary entraining table or spider driven in synchronism with the conveyor.  The entraining elements rotate about a fixed supporting surface and are attached tangentially to a hub so that the fish supplied to the thus formed chambers are charged with a pushing force or component effective in an inward or outward direction depending on the direction of rotation, which component effects a precise positioning of the fish by engagement of the mouth portion with a stop  just before the trans-mitting to the conveyor occurs.

IPC: H03F3/26
Filed: 1991-02-11
Granted: 1995-12-05
Abstract: A receiver is described for optical signals which are amplitude modulated with broadband radio frequency signals. The re-ceiver includes an optical detector (20) which receives the incoming optical signal and generates a radio frequency electrical sig-nal which varies with the power level of the incoming optical signal. This electrical signal is applied to a pair of amplifiers (100, 200) which are connected in a push-pull relationship. In a preferred embodiment, a tuning network (500) is connected between the two amplifiers for optimizing the amplification of a selected band of radio frequencies.

Title: Spacing member
Inventor: SVENSSON THOMAS
IPC: A61C8/00
Filed: 1991-12-31
Granted: 2000-05-16
Abstract: The invention relates to a spacing member arranged between a securing element (fixture) implanted in the facial bone (the cranium) and an extraoral prosthesis, in particular a facial prosthesis. The spacing member comprises a base portion (1) intended to cooperate with the upper portion of the securing element, and an extension part (8, 8') which forms an attachment point for the prosthesis. The extension part (8, 8') is designed in such a way that it permits attachment of~the prosthesis in a direction (attachment direction] which forms essentially a right angle to the longitudinal direction of the extension part. The spacing member combines the two conflicting requirements which exist particularly in the case of an orbital prosthesis, namely secure anchoring in the bone (radial,attachment of the securing elements) and a more favourable attachment direction (axial) for the prosthetic work.
