Abstract: 1399022 Working at specified temperatures NORANDA MINES Ltd 31 May 1972 [20 Aug 1971] 824/75 Divided out of 1399021 Heading B3V [Also in Division C7] Quaternary Zn-Al alloys which have a eutectoid and are conditionable to exhibit superplasticity are so conditioned by a method which comprises, with associated prior heat treatment, hot working the alloys at a temperature between 205‹ C. and the eutectoid temperature (e.g. 275‹ C.). The hot working may be rolling with a reduction of 90 to 95%, or extrusion which may be followed by driving. The alloys are homogenized and quenched prior to hot working. In an example an alloy of 22% Al, 1À4% Cu, 0À05% Mg, balance Zn is soaked for 2 hours at 350‹ C., quenched in ice water, extruded at 250‹ C. and cold drawn by 31%. In a further example an alloy of 22% Al, 1À0 Cu, 0À05% Mg, balance Zn was similarly homogenized and quenched, then rolled at 250‹ C. with 90% reduction. The Specification further discloses a treatment including rolling at 350‹ C. or extruding at 250‹ C., homogenizing at 350‹ C. and quenching. The Zn alloys may include the following weight per cent:- Samples of the last alloy were rolled at 316‹C., homogenized at 316‹ C. and quenched. They were then rolled at various temperatures between 100‹ C. and 270‹ C. Specification 1,399,021 is referred to.

Abstract: 826,422. Panoramic kinematography. C-M EQUIPMENT CORPORATION. Jan. 9, 1957 [May 8, 1956], No. 916/57. Classes 97(1) and 98(1)  Films intended for projection to form a mosaic image have marginal portions of their frames vignetted across the regions of overlap where the same parts of the subject are recorded on two films. Thus three films 22, 23, 24, Fig. 5 are vignetted during printing at 16, 17, 19, 21 to give zones of density increasing outwardly. Three white cards are provided, one for each film, with groups of lines of graded thickness and spacing, as shown in Fig. 3, in one or both margins as required. The lines are blended together by air brush. The cards are then photographed to produce masking films. During printing the positive stock films are exposed first to the negative films and then to the masking films. Alternatively the vignetting areas may be printed on first in apparatus as shown in Fig. 6. An illuminated diffusion screen 33 is disposed behind the device 34 which is opaque in the centre but has marginal slits and is imaged by the lens 35 in the camera 29. After exposure the positive stock is printed from the negative.

Title: Heat development controller
Inventor: NAKAUCHI KENJI
IPC: G03D13/00
Filed: 1985-01-07
Abstract: PURPOSE:To hold the temperature of a heat development photosensitive material constant by providing a deviation detecting circuit for the deviation of the resistance value of the heat development photosensitive material from a specific resistance value and a control circuit for electric power supplied to a feed heating body according to the output of said circuit. CONSTITUTION:When the temperature of the feed heating body 1 is low and its resistance value Rt is smaller than a desired value, a phase control circuit 8 increases the firing angle of a triac 3 to increase the level of a current which flows through the feed heating body 1. When the temperature of the feed heating body 1 is high and its resistance value Rt is larger than the desired value, on the other hand, the firing angle of the triac 3 is decreased to decrease the current level. When an AC power source 2 is determined,a voltage V1 is constant, so when the resistance value Rt of the feed heating body 1 is held constant, a voltage V2 is also constant, and consequently the output voltage Vf of an operational amplifier 5 is held nearly as high as a reference voltage Vr.

Title: Electromagnetic flowmeter
Inventor: SUDOU TAKESHI
IPC: G01F1/60
Filed: 1979-01-10
Abstract: PURPOSE: To obtain a flow signal stable and highly accurate regardless of changes in the application conditions by employing DC excitation.  
     CONSTITUTION: An excitation coil 2 composing a detector 1 is excited by the DC power source 16. As a result, DC current flows through the excitation coil 2 from the DC power source 16. Applied to a measuring fluid 4, DC magnetic flux ϕ induces a detection signal E s  as a DC signal in proportion to the function between the magnetic flux density and the fluid speed. The signal E s  is applied to an amplifier 9 via a change-over switch i driven by a drive circuit 15, subjected to a sampling with a sampling hold circuit 10 and a smoothing with an equalization circuit 11 and then, outputted from an amplifier 12 as a desired signal I 0 . The DC excitation eliminates noise voltage otherwise caused by magnetic induction in the detector 1. Thus, there is no variation of the zero point due to changes in application conditions of the temperature, fluid pressure and the power supply voltage, thereby getting rid of eddy-current loss and hysteresis loss.

IPC: A23L29/10
Filed: 1995-01-06
Abstract: PURPOSE: To obtain the subject preparation composed of a sucrose fatty acid ester having a specific HLB, an enzyme-treated lecithin and an enzyme- hydrolyzed lecithin and capable of preserving a milk drink with an excellent stability and without separating oil for a long time at a high temperature. CONSTITUTION: This preparation is produced by compounding a sucrose fatty- acid ester having HLB of 15-16 (e.g. sucrose palmitic acid ester), an enzyme- treated lecithin and an enzyme-hydrolyzed lecithin. The enzyme treated lecithin is obtained by treating a soybean lecithin with phospholipase D to cleave an ester linkage between the phosphoric acid of the phospholipid and a nitrogen- containing base followed by the reaction of the lecithin with glycerin to lead to phosphatidylglycerol and accordingly to increase hydrophilicity. The enzyme- hydrolyzed lecithin is obtained by treating the soybean lecithin with an enzyme, phospholipase A2 , to hydrolyze the ester linkage at β-position and accordingly to increase the number of hydroxyl groups and hydrophilicity.  The obtained preparation can preserve a milk drink without separating oil even stored at a high temperature for a long time e.g. in a hot vender and can obtain a milk drink having an excellent emulsion stability for a long time only by adding it to milk drink.
