Title: Process for producing black vinegar and black vinegar produced by the process
Inventor: OGASAWARA YASUSHI
IPC: C12J1/04
Filed: 2008-05-19
Abstract: It is intended to provide a process for producing black vinegar, which is rich in saccharides originating in rice and barley but free from sedimentation, and the black vinegar produced by this process. Namely, a process for producing black vinegar which contains from 8 to 50% by volume of saccharides originating in rice and/or barley characterized by comprising mixing a saccharification liquor of rice and/or barley with a fermentation liquor containing spirit followed by acetic acid fermentation, and regulating the oxalic acid concentration in the final black vinegar product to 36 ppm or below, preferably 30 ppm or below. To lower the content of oxalic acid in the black vinegar, it is effective to store under stirring the saccharification liquor of rice and/or barley or the fermented liquor after the completion of the acetic acid fermentation. It is also intended to provide black vinegar produced by the above processes which scarcely suffers from sedimentation of oxalic acid salts and is suitable for drinking.

Title: CMOS negative resistance circuits
Inventor: SWEE YONG KHIM
IPC: H03F3/347
Filed: 2008-05-29
Abstract: A three-transistor CMOS negative resistance circuit has a good frequency response and low current consumption. The drain current of Q3 is mirrored by Q2 and Q1 to the gate node of Q3 so that the current drawn by Q1 falls as the input voltage rises. The circuit may be used as an amplifier or oscillator, or to simulate a tunnel diode. The circuit may also be used to increase Q factor or resistance. The circuit, and its dual using transistors of inverted polarity, may be used to provide small-signal negative resistance in any current-voltage quadrant (figures 5,6,9 and 10). A large-signal negative resistance with a volt-ampere curve passing through the origin may be implemented (figure 15).

Title: Improvements in and relating to price change or rate change gearing for use in prepayment mechanism and the like
IPC: G07F15/08
Filed: 1946-04-01
Abstract: 627,894. Prepayment mechanism for meters. CROMPTON PARKINSON, Ltd., and WICKHAM, A. H. April 1, 1946, No. 10071. [Class 27] [Also in Group XXIV] Price-changing mechanism. In a pricechange gear comprising a stack of graded gears 7 alternatively engageable by a selector wheel 10, movement of the selector wheel longitudinally of the gears 7 is effected by rotation of a screwed control spindle 9, such rotation also reciprocating a guide which both rocks the selector wheel out of and into mesh with the successive gears 7 and adjusts the radial meshing position of the selector wheel at each step of the gear stack. The selector wheel 10 is mounted in a carrier 11 free to rock and slide on a square shaft 12 by which the wheel is driven through a pinion 19 also located between the two limbs of the carrier. An extension 20 of the carrier engages a part helical slot 21 in a segmental guide 15 extending between end plates 16 rockable about the square shaft 12. Slots 18 in these end plates embrace cams 17 at the ends of the screwed control spindle 9 which also carries a nut 23 connected to arms 22 embracing the carrier 11. When the spindle 9 is rotated, the nut 23 traverses the carrier 11 and selector wheel 10 longitudinally of the gears 7 and through one step for each revolution. At the same time the cams 17, through the segmental guide 15, rock the carrier to and fro, first to disengage the selector wheel and then to re-engage it with the next gear of the stack 7, the part helical slot 21 in the guide being dimensioned so as to ensure accurate meshing. An indicator dial 25 shows the setting of the gear, and is formed as a Geneva Wheel for stepwise movement by the control spindle 9 and to arrest the spindle at its limits of movement. Specifition 489,394 is referred to.
Patent GB-981112-A (GB)
Title: Improvements in or relating to pulse amplifying circuits
IPC: H03K5/01
Filed: 1962-03-16
Abstract: 981,112. Transistor pulse circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 16, 1962 [March 20, 1961], No. 10167/62. Heading H3T. A circuit for converting pulses of either polarity into pulses of constant polarity comprises a transistor biased below the bend of the collector characteristic and having a load in the collector circuit and an emitter resistor of high value compared to the base-emitter forward resistance. The collector load resistor 2 should preferably be equal in value to the emitter resistor 5. Transistor 1 is normally saturated so that negative-going pulses are transferred to the output terminal 4 without change in polarity. Positive-going pulses, however, drive the transistor out of saturation and are hence amplified and inverted. Diode 9 is normally non-conductive but is driven into conduction by positive-going pulses so that capacitor 10 is connected across the emitter resistor 5 thus preventing negative feedback and allowing the transistor to be cut off by a positive-going pulse of comparatively low amplitude. The amplitude of pulses at terminal 4 may be limited by a further transistor arranged to be either normally saturated or normally cut off.

Title: Improvements relating to kinematography

Filed: 1927-04-14
Abstract: 295,643. Bernardi, A., Burger, P. L., and Auto Natural Color Films, Ltd. April 14, 1927. Colour kinematography.-A kinematograph projection system using films of the kind in which each normal picture space is occupied by triple pictures arranged two side by side of half the usual depth and the third midway above or below the other two, utilizes a group of three rhomboidal prisms, or optically equivalent elements, by which the beams are spaced apart to enable projection lenses of normal size to be used. The photographs may be taken with an ordinary kinematograph camera having lenses triangularly placed and a gate divided into three spaces by webs forming a T-piece, but such small lenses are insufficient for projection purposes. The rays of light from the source a pass through a condenser c to the film gate, before which small angled prisms d are placed to compensate for the uneven distribution of the light. Beyond the gate and before the projection lenses g<2>, b<2> are placed prisms g<1>, r<1>, b<1>, with their entrance faces coplanar and arranged as shown in Fig. 4. To enable the exit faces of the prisms to be increased in size so as to cover the projection lenses and at the same time to ensure that the pictures are centrally arranged with reference to the prisms, the arrangement shown in Figs. 9 and 10 is provided in which the prism B is fitted into sloping recesses cut in the prisms R, G, the pictures ra, ga, ba being on the centre lines of the prisms. In a modification of this construction the inserted prism has its upper angular edge removed slightly to avoid crowding the exit beams into the adjacent corners of the prisms. The colour filters are mounted in the gate as described in Specification 295,662.

In a modification of the system the digital difference signal may be supplied to the binary counter 13, as shown by the dotted connection 17a so as to influence the digital difference signal obtained in the next cycle of operations.

IPC: C08G63/85
Filed: 1965-03-11
Abstract: In the manufacture of highly polymeric polyesters by polycondensing a glycol ester of an aromatic dicarboxylic acid, there is used as a polycondensation catalyst a titanium iodate compound, e.g. titanium di-iodate, titanium dihydroxide di-iodate or its hydrate, titanium tetraiodate or its hydrate, titanium dihydrogen hexaiodate or its hydrate, or the alkali metal or ammonium salts of titanium dihydrogen hexaiodate. If the initial glycol ester is made by an ester-interchange reaction, the titanium iodates may also be used as catalysts for this reaction possibly in admixture with known catalysts (e.g. zinc acetate). Specified polyesters are those of terephthalic or pyridine dicarboxylic acids and ethylene glycol or cyclohexanedimethanols. Examples describe the manufacture of polyethylene terephthalate by reacting dimethyl terephthalate and ethylene glycol.
