Title: Procedure for production of vehicle wheels
Inventor: BERG OTTO
IPC: B21K1/32
Filed: 1992-04-16
Abstract: Abstract A vehicle wheel made of light metal and consisting of a hub and a rim surface is produced by a process comprising the steps of producing a substantially disc-shaped crude billet  from an extruded bolt or a similar rounded solid metal body, heating of a crude billet to a hot rolling  temperature  and  subsequently orbitally rolling the crude billet so as to  obtain  a  rotationally  symmetric preformed material, splitting off of the outer portion of the preformed material, and afterwards forming a rim surface by spinning  the  outer,   split-off  rim portion.              As an   alternative,   the   preformed material  after  orbital  rolling  and before splitting can be compressed or cold forged in order to obtain a desired specified design  for the hub  of the wheel.

Title: Generalized viterbi algorithm with tail-biting
Inventor: CHENNAKESHU SANDEEP
IPC: H03M13/35
Filed: 1992-05-07
Abstract: RD-20,626 ABSTRACT           A method and apparatus for digital radio communication employs separation of a frame of data to be transmitted into key bits, critical bits and unprotected bits. The key bits are processed to provide parity bits. The parity bits, and key bits are convolutionally encoded using a tail-biting scheme and merged with unprotected bits, and then transmitted. At the receiver, the decoder splits the received data into convolutionally encoded bits and unprotected bits, and trellis decodes the convolutionally encoded bits into a number of possible paths through a trellis using a generalized Viterbi algorithm.  The tail-biting scheme reduces the number of bits that must be transmitted. Paths having errors in the key bits are rejected, and the path having the best metric without key bit errors is used in decoding the transmitted information. In the event that there is no such path, a previously selected path is substituted and decoded.

Title: Surgical method and apparatus for fusing adjacent bone structures
Inventor: RAY CHARLES D
IPC: A61B17/16
Filed: 1990-09-18
Abstract: A fusion cage (10) having an external thread (12) can be surgically inserted into a threaded bore extending laterally between the adjacent bony structures such as two vertebrae (94, 95) with the thread (12) penetrating into cancellous bone of each of the vertebrae (94, 95). The fusion cage (10) is easily screwed into place by hand without damage to the bony structures (94, 95). Cage (10) is then packed with a bone-growth-inducing substance such as cancellous bone. When a pair of such cages (10) are implanted between adjacent vertebrae (94, 95), patients have been able to sit without pain by the second or third day, much earlier than has been possible in prior spinal fusions except those involving steel plates and screws. Eventually, the ingrowth of bone through perforations (13) in the valley (14) of the thread (12) of the fusion cage (10) forms a permanent interconnection between the two bony structures (94, 95).
Patent CA-2074253-A1 (CA)
Title: Packaging method
Inventor: GARWOOD ANTHONY J M
IPC: B65B31/02
Filed: 1991-01-16
Abstract: A method of packaging goods such as red meats is disclosed. The goods (5) are packaged on a base (1) with an inner skin lid (11) which at least partially skin packs the goods (5) to the base (1) to hold the goods (5) to the base (1). An outer lid (7) is placed over the inner skin lid (11) and gas pressure is reduced therebetween causing the inner skin lid (11) to be urged relatively towards the undersurface of the outer lid (7). This, in turn, displaces unwanted gases between the inner lid (11) and the outer lid (7). The outer lid (7) is then sealed to the inner lid (11) and the base (1). The inner skin lid (11) is of a material which will allow a required gas such as 02 to penetrate the inner skin lid (11) when the outer lid (7) is opened, removed or ruptured to, in turn, allow the red meat, if discoloured, to bloom to a red colour. The method enables unwanted gases such as O2 to be substantially excluded from the packaging until the outer lid (7) is opened, removed or ruptured.

Abstract: Abstract of the Disclosure Anti-idiotypic antibodies that mimic tumor necrosis factor (TNF) activity.  The antibodies may be raised in one species (e.g. a rabbit) using a monoclonal anti-TNF antibody from another species (e.g. a mouse) as an immunogen.  Such anti-idiotypic antibodies were cytotoxic to TNF-sensitive cell lines.  The cytotoxic activity of the anti-idiotypic antibodies can be neutralized by antibodies that bind to TNF.  The anti-idiotypic antibodies may be useful themselves as TNF antagonists or as TNF agonists, and may also be the basis for a new group of TNF agonists or antagonists.

Title: Stabilized solid pharmaceutical preparation and method of producing the same
Inventor: MAKINO TADASHI
IPC: A61K31/135
Filed: 1993-04-16
Abstract: ABSTRACT     A solid pharmaceutical preparation contains 5 to 50% by weight of ibuprofen and 0.1 to 10% by weight of phenylpropanolamine or a pharmaceutically acceptable salt thereof which are stabilized.  The solid pharma-ceutical preparation can be produced by means of granu-lating with carriers at least one active ingredient, preferably both ingredients separately into the ibupro-fen group and the phenylpropanolamine group, and mixing the former with the latter to enhance the stability of the active ingredients.  Preferably, in the phenylpro-panolamine group, the amount of any reducing sugar is minimized to such an extent as to maintain the stabili-ty of the active ingredient.  The above pharmaceutical preparation is suitable for a cold remedy, which has a more excellent pharmacological activity based on ibu-profen, less decomposability of phenylpropanolamine and less change of external appearance of the preparation due to low compatibility between phenylpropanolamine and ibuprofen.  Therefore, the pharmaceutical prepara-tion has longer period of quality assurance.

Title: Nitrogen-free active ingredient component in fabric softener formulations
Inventor: BROCK MICHAEL
IPC: D06M13/342
Filed: 1993-05-12
Abstract: Abstract:            The invention relates to nitrogen-free active ingredient components in fabric softener formulations and to the use thereof.            The nitrogen-containing cationic fabric softener active ingredient components  used  hitherto  often  have  an unfavourable aquatic toxicity and are undesirable in view of the possibility of nitrosamine formation.   A novel, nitrogen-free fabric softener active ingredient component is therefore proposed. It comprises alkoxylated natural fats or oils and may be used on its own or in combination with  conventional  cationic  nitrogen-containing  active ingredient components with and without the addition of dispersants,   emulsifiers   and/or   solubilisers.     A synergistic increase in effect is obtained in some cases. A   nitrogen-free   or   low-nitrogen   fabric   softener formulation with a high softening potential, i.e. good antistatic and rewetting properties, may thus be prepared.

Patent CA-2097067-A1 (CA)
Title: Pneumatic hammer
Inventor: KLEMM GUNTER W
IPC: E21B1/32
Filed: 1992-10-23
Abstract: A pneumatic hammer is provided with an adjusting means (37) dependent on the supply pressure, which adjusts the stroke length of the working piston (16). Thereby, the same pneumatic hammer may be operated both at low and high supply pressures. With high supply pressures, either the early ending of the acceleration phase or the early start of the compression phase or the shortening of the working cylinder shortens the stroke length. Thereby, the pneumatic hammer performs impacts with a substantially constant single-impact energy, regardless of the supply pressure. High supply pressures increase the impact frequency. This results in a considerably improved efficiency at a high drilling capacity, a reduced wear and a reduced risk of ruptures of the components of the hammer.
