Title: Refractory lining system for high wear area of high temperature reaction vessel
Inventor: HUBBLE DAVID H
IPC: F27D1/12
Filed: 1996-10-21
Abstract: A refractory-lined high temperature reaction vessel comprises a refractory ring lining constructed of refractory brick, a cooler, and a heat transfer medium disposed between the refractory ring lining and the cooler.  The refractory brick comprises magnesia (MgO) and graphite.  The heat transfer medium contacts the refractory brick and a cooling surface of the cooler, and is composed of a material that accommodates relative movement between the refractory brick and the cooler.  The brick is manufactured such that the graphite has an orientation providing a high thermal conductivity in the lengthwise direction through the brick that is higher than the thermal conductivity in directions perpendicular to the lengthwise direction.          The graphite preferably is flake graphite, in the range of about 10 to 20 wt%, and has a size distribution selected to provide maximum brick density.  The reaction vessel may be used for performing a reaction process including the steps of forming a layer of slag on a melt in the vessel, the slag having a softening point temperature range, and forming a protective frozen layer of slag on the interior-facing surface of the refractory lining in at least a portion of a zone where the surface contacts the layer of slag, the protective frozen layer being maintained at or about the softening point of the slag.

Abstract: PCT No. PCT/FR96/00779 Sec. 371 Date Jan. 24, 1997 Sec. 102(e) Date Jan. 24, 1997 PCT Filed May 24, 1996 PCT Pub. No. WO96/37454 PCT Pub. Date Nov. 28, 1996The present invention concerns a process for the preparation of 3-carboxy-4-hydroxybenzaldehydes and derivatives thereof from phenolic compounds carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions. The invention also concerns the preparation of 4-hydroxybenzaldehydes from 3-carboxy-4-hydroxybenzaldehydes. More particularly, the invention concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, respectively known as "vanillin" and "ethylvanillin". The process for the preparation of 3-carboxy-4-hydroxybenzaldehyde is characterized in that the group in the 2 position in a phenolic compound carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions is selectively oxidized to a carboxy group, and optionally a hydroxymethyl group in the 4 position is selectively oxidized to a formyl group. A successive decarboxylation step for a 3-carboxy-4-hydroxybenzaldehyde produces a 4-hydroxybenzaldehyde.

Abstract: A hand-held utility knife (20) has two handle portions (22, 23) hinged together at the rear end (26) of the handle (21) by means of two lugs (36, 37) of one handle portion (22) projecting into two recesses or cavities (38, 39) of the other handle portion (23) and retained therein behind two lips (53a, 53b) except when almost closed together, when the two handle portions (22, 23) can be separated and reconnected. In order to prevent inadvertent separation of the two handle portions (22, 23) at their rear ends (24, 25) when the handle is closed and the clamping device (27) is screwed up tight, the lugs (36, 37) have abutment portions (61, 62) which engage abutments (65, 66) inside the two recesses or cavities (38, 39). The abutments (61, 62, 65, 66) are positioned on one side of the hinging axis (34) so that they move apart when the handle (21) is opened. Hence the abutments (61, 62, 65, 66) do not interfere with the hinging of the handle portions (22, 23) nor with their separation and reconnection.

Inventor: JONES LAMAR A
IPC: B66F9/14
Filed: 1997-03-24
Abstract: A storage and retrieval machine has a telescopically extendible shuttle assembly and having spring tensioned shuttle idler pulleys for the slave drive members, preferably chains, of the shuttle assembly. A spring, preferably a die spring, exerts a biasing force on each idler pulley which opposes forces imposed on the idler pulley by the corresponding slave chain. Pre-tensioning the idler pulley in this manner assures adequate tension on the slave chain to prevent or at least inhibit undulations in plate movement which otherwise could occur during telescopic extension and retraction of the shuttle assembly if the slave chain were inadequately tensioned.  Use of the spring loaded idler pulley also obviates the need to over-tension the slave chain and prevents or inhibits premature wear and failure of the idler pulley, pulley bearing, and/or chain.

Title: Call forwarding on busy or no answer when call waiting is active
Inventor: MALIK DALE W
IPC: H04M3/533
Filed: 1997-06-20
Abstract: A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.

Title: Hydroxylamine derivatives useful for enhancing the molecular chaperon production and the preparation thereof
Inventor: BIRO KATALIN
IPC: C12N5/0793
Filed: 1996-11-01
Abstract: A method of increasing expression of a molecular chaperon by a cell and/or enhancing the activity of a molecular chaperon in cells is provided. The method comprises treating a cell that is exposed to a physiological stress which induces expression of a molecular chaperon by the cell with an effective amount of a certain hydroxylamine derivative to increase the stress. Alternatively, a hydroxylamine derivative can be administrated to a cell before it is exposed to a physiological stress which induces expression of a molecular chaperon by the cell.  Preferably, the cell to which a hydroxylamine derivative is administered is a eukaryotic cell. The hydroxylamine derivative corresponds to the formulae (I) or (II). The invention also provides novel hydroxylamine derivatives falling within the scope of the formulae (I) and (II) as well as pharmaceutical and/or cosmetical compositions comprising the said compounds.
