Title: Casein gel, and preparation method and application therefor
Inventor: FENG ZHANG
IPC: A23C9/12
Filed: 2023-06-28
Abstract: A preparation of protein gel, in particular casein gel, and a preparation method and application therefor. Raw materials of the casein gel include casein and/or casein sodium salt, sodium alginate, a calcium ion chelating agent and an acidiﬁcation sustained-release agent. Under the action of the calcium ion chelating agent slowly releasing calcium ions, the casein and/or casein sodium salt and the sodium alginate are mutually interpenetrated to form a dual 10 network structure, and at the same time, under the action of slow acidiﬁcation of a pH sustained-release agent, the casein and/or casein sodium salt and the sodium alginate are acidized to an isoelectric point of the casein, so as to cause a reaction system to form the casein gel of the present application. The casein gel is excellent in rheological characteristic, high in hardness, strong in water-holding capacity, and stable in structure.

Abstract: 1,180,744. Seaming non-metallic sheet material. BRITISH VISQUEEN Ltd. 31 May, 1967 [6 July, 1966], No. 30288/66. Heading B5K. A heat seal is formed between at least two layers 1, 1<SP>1</SP> of plastics film by pressing together the layers 1, 1<SP>1</SP> between two surfaces at least one of which is heated to a temperature sufficient to effect heat sealing and supplying by conduction additional but less intensive heat on at least one side of the sealing area so as to extend the area of temperature gradient between the heat sealing area and the cold area of the film layers 1, 1<SP>1</SP>. As shown, the layers 1, 1<SP>1</SP> are formed by the walls of a web of flattened tubular film. Heat sealing members 2, 2<SP>1</SP> have secured thereto annealing members 3, 3<SP>1</SP> of lower thermal conductivity than the members 2, 2<SP>1</SP> and comprising silicone rubber blocks which, when the members 2, 2<SP>1</SP> are spaced apart, stand proud of the heat sealing surfaces. A knife 4 is advanced when the members 2, 2<SP>1</SP> are closed to sever the layers 1, 1<SP>1</SP> to form individual bags each with the annealed side of the seam facing the interior of the bag. In another embodiment (not shown), the annealing members are made of rigid material and stand slightly proud of the sealing surfaces but are spring-loaded so as to enable the sealing members to be brought together during sealing. In a further embodiment, the surfaces of the annealing members may be level with the surfaces of the sealing members. The invention is also applicable to machines in which a single heated member works against a surface or in which the film layers are carried by steel bands between heated sealing members. The heat sealing member(s) are made of metal, e.g. mild steel, stainless steel or aluminium. Specified materials for the annealing member(s) are silicone rubber; laminates of paper and thermosetting resins, e.g. phenol formaldehyde resins; glass cloth/epoxy resin laminates; wood-filled or fibre-filled thermosetting resins; hard asbestos and glass-filled nylon. Specified films to be sealed are polythene, polypropylene and polyvinyl chloride films having a thickness of at least 0À006 inch.

Title: Cheese packing shop air-conditioning system - comprises pipes with lateral openings above cheeses on each plank
IPC: A01J25/16
Filed: 1980-03-24
Abstract: The air-conditioning system is for a cheese-packing shop with the cheeses lying on planks.

Title: Sampling appts. for coking plant - takes samples from slope down which coke emerges from coking chamber to catch it before degradation
IPC: G01N1/20
Filed: 1982-03-17
Abstract: When a sample of coke is taken to check the size, dryness, strength, etc. of the pellets, it is important to select samples from as near the coking chamber as possible, so that tests can be carried out before the material degrades, and can also tell the operator about the condition of the coking chamber. This sampling appts. extracts a large sample from the stream of coke as it emerges down a slope (30) from the coking chamber. The coke slides into a tray (32). When sufficient coke is in the tray, lifting motors (34) mounted on a crane gantry (33), lift the tray clear of the slope and carry it to a dividing mechanism. The latter (36) takes smaller samples of the coke in the tray, and the remainder of the tray contents are returned to the processing plant.

Patent NL-8801590-A (NL)
IPC: H04L12/28
Filed: 1988-06-22
Abstract: A network in which not only the transmission of control signals and information signals in transmission sections (1, 1a), but also the switching in switching devices (24) and the joining or the separation of the control signals and information signals take place in the optical domain. The control signals (c) and the information signals (d) in the optical domain are distinguishable from each other, and they are both coupled in and out in one and the same optical conductor (1, 1a). For distinguishing the control signal from the information signal the transmission modes (e.g. the wavelength or the polarization mode) thereof can be different. A distinction between the control signal and the information signal can also be effected by opposite directions of transmission; for controlling a switching device a control signal is then transmitted to the switching device via a glass fibre which at the same time serves for the transmission of information signals in an opposite direction.
Patent NL-9000077-A (NL)
IPC: H05B41/04
Filed: 1990-01-11
Abstract: The invention relates to a circuit arrangement for igniting a high-pressure discharge lamp (6), in which ignition voltages are generated by means of discharges from two capacitors (10, 14) through a primary winding (12) of a transformer. During this, the lamp (6) is connected to a secondary winding (4) of this transformer. According to the invention, one capacitor (14) is charged to a higher voltage than the other capacitor (10), the two capacitors being discharged alternately through breakdown elements (11, 15) associated with the capacitors (10, 14, respectively). An ignition pulse with a low peak value for igniting the lamp (6) in the cold state is then followed by an ignition pulse with a high peak value for igniting the lamp (6) if it should be in the hot state. <IMAGE>

Abstract: PCT No. PCT/EP94/03171 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Sep. 23, 1994 PCT Pub. No. WO95/09513 PCT Pub. Date Apr. 6, 1995Known methods for determining base station locations are based on human choice of that location which has the lowest degree of coverage (i.e. locally too little or no field strength present of neighboring base stations). The method according to the invention involves automated determination of base station locations by calculating, for each location, a number which is a function of a parameter associated with that location (telephone traffic, field strength, motor traffic) and of parameters belonging to adjoining locations, and by assigning a base station to the location having the most extreme number. Then the parameter associated with that location, and the parameters associated with adjoining locations are each adjusted on the basis of an adjustment function associated with the base station, and new numbers are calculated which are a function of the new, adjusted parameters, etc.
