Title: Process for tanning edible collagen casing
IPC: A22C13/00
Filed: 1974-01-07
Abstract: 1445033 Tubular collagen films TEE-PAK Inc 7 Jan 1974 [8 Jan 1973] 00663/74 Heading B5B [Also in Division C3] A collagen slurry is extruded into a tubular film, coagulated, tanned and dried. The tanning proceeds in two steps: (i) immersing the coagulated gel tube, which must be substantially free of ammonia or ammonium salts, in a first bath consisting of a substantially saturated aqueous solution of an alkali metal salt of a strong acid containing 0À01 to 5 wt. per cent, but sufficient, aldehyde to tan the tube. This bath has a pH of 3À0 or less and a temperature of 5 to 40 C. and the treated casing contains sufficient aldehyde and salt to maintain its strength, but no more than 10 p.p.m. free aldehyde; (ii) immersing the aldehyde-impregnated casing in a second bath at 5 to 40 C. consisting of a substantially saturated aqueous solution of an alkali metal salt of a strong acid, containing strong alkali to give a pH of at least 12, for a time sufficient to neutralize the acid in the casing and to fix the aldehyde. Preferred aldehydes are formaldehyde, glyoxal and glutaraldehyde.

Title: Improvements in or relating to the manufacture of cellulose esters
IPC: C08B3/28
Filed: 1935-01-10
Abstract: Cellulose esters are precipitated from solutions by means of organic non-solvents for the esters, and the solvents removed from the precipitated esters by distillation.  Part of the solvent may be removed by distillation before the precipitation of the cellulose ester.  Examples of suitable precipitants are amyl alcohol, amyl acetate, liquid hydrocarbons, ethylene glycol, and methyl alcohol. In an example, an esterification solution comprising cellulose acetate, acetic acid and sulphuric acid is treated with sodium acetate to neutralize the sulphuric acid, and heated in a vacuum to distil off part of the acetic acid.  The cellulose acetate is precipitated by means of amyl alcohol (or amyl acetate), and the mixture distilled to dryness.  In a further example, xylene is added in two stages to a solution of cellulose acetate in acetic acid to precipitate the ester, and the mixture is heated to dryness in vacuum.

The temperature sensor may comprise a set of deformable capsules immersed in an expansible fluid and operating a pilot valve which operates the valve 22. The heat exchanger 10 may be located outside the tank R and connected to it by pipes. The hydraulic motor 14 may be arranged at the hub of the blower.

Title: Apparatus and method for driving ink jet printer
Inventor: RICH LEONARD G
IPC: B41J2/07
Filed: 1993-07-08
Abstract: A circuit and related method are provided for driving an ink jet printer to achieve a consistent velocity of ejected ink drop despite differences in the time elapsing between successive drops. Timing pulses timing the ejection of drops each trigger the production of fundamental waveform. This waveform is then multiplied by a multiplying factor selected from a look-up table in response to the time elapsing between the timing pulse causing the generation of the waveform and the preceding timing pulse, and the modified waveform so produced is used to drive the printing head through a power ampilfier. The multiplying factor is one chosen by experiment as that required to produce the desired ink jet velocity. In a preferred embodiment both the fundamental waveform and the multiplying factor may each be obtained through the use of an associated PROM so that the waveform shape and multiplying factor versus dot frequency characteristic may be readily changed to suit the particular printer head in question.

Title: Thyristor fault detecting circuit of capacitor charging device
Inventor: KANAI TAKEO
IPC: G01R31/26
Filed: 1984-01-06
Abstract: PURPOSE:To prevent malfunction by preventing the decision that a thyrstor is faulty even if the terminal voltage across the thyristor is smaller than a set voltage detection value when the current flowing through a capacitor charging device is smaller than a set value. CONSTITUTION:A source voltage is controlled by reverse parallel thyristor type AC voltage regulating device 1 and applied to a transformer 2, whose secondary- side volage is rectified by a rectifier 3 to flow a charging current to a capacitor 5 through a load 4. At this time, a terminal voltage detecting circuit 2 for the thyristor 11 detects whether a voltage is applied to the thyristor 11 during a half cycle or not. A current transformer 22, on the other hand, detects the charging current flowing to the secondary-side capacitor 5 and a level detector 23 detects whether its output is larger than a set current detection value or not. Then, a thyristor fault deciding circuit 24 judges a fault when no voltage is applied to the thyristor 11 during a half cycle and the charging current flowing to the capacitor 5 is larger than the set value.
