Abstract: A method for the cooling of a heated, e.g. heat-sterilized, flow containing particles of foodstuff character. The flow is separated into a high-particle and a low-particle fraction which is cooled separately and is used later as a cooling medium for the cooling of the high-particle fraction. The method is intended in the first place to be used in so-called aseptic packaging according to which the heat-treated, cooled foodstuff product, e.g. fruit soup, vegetable soup, meat broth etc. is packed in sterilized packing containers, or in packing containers manufactured from sterilized packing material, under aseptic packing conditions.

Abstract: An apparatus having a signal conducting line (14) with first (22) and second (26) ends is provided. The signal conducting line (14) is configured to allow changes of impedance at space locations therealong. The signal conducting line (14) is supported by a substrate (12). A signal generator (24) is operably connected to the first end (22) of the signal conducting line (14), the signal generator (24) generating a measuring signal along the signal conducting line (14). The measuring signal has a predetermined characteristic, over a plurality of time intervals, when the measuring signal is undisturbed. When a disturbance is created in the measuring signal by, for example, the touching of the signal conducting line (14) by a fingertip, the characteristic of the measuring signal varies from a predetermined deviation. Processing circuitry (36, 40) is operably connected to the first end (22) of the signal conducting line (14) so that the time interval at which the measuring signal is disturbed can be determined. The processing circuit (36, 40) includes a correlating circuit, which correlating circuit corresponds the time interval with one of the spaced locations.

Abstract: In known heating/air-conditioning systems, the cold air emerging from the central nozzles can lead in particular in an air-conditioning and reheat mode to draught phenomena in the passenger compartment of the vehicle, in particular when the nozzle arrangement is unfavourable. It is proposed to divide up the airstream flowing into the head space into an essentially vertically upward flowing portion in a branch line (11) by means of so-called vertical outflow nozzles or top nozzles (19) and a predominantly horizontally outflowing portion (12) by means of so-called central nozzles (18). At the entrance to the branch line (11) there is a supplementary flap (20) which can be opened and closed in proportion to the opening angle of the bypass flap (8) at the heat exchanger (7). The supplementary flap (12) can be also connected to a water valve or actuated by adjustment motors which can be additionally influenced by a solar sensor (15). In place of a supplementary flap (12) in a branch line (12), a modified, essentially horizontal, automatic central nozzle with a pivot flap can also be provided which permits an essentially vertically upwardly directed expulsion of air into the passenger compartment of the vehicle. <IMAGE>

Abstract: Material, such as natural ground and precipitated calcium carbonate, when modified by surface-treatment with a cationic polymer, has been discovered to be highly effective as a filler material in the making of paper. Utilization of this type of filler material greatly improves the papermaking process by reducing the usage of wet end sizing agent, improving opacity, improving filler retention in the furnish, and causing better drainage on the papermachine, all of which result in the production of a high quality paper having excellent opacity and tensile strength characteristics. The nature of the polymer-modified filler material, the process for its preparation and the method of its use in papermaking are disclosed.

Abstract: A continuous sheet 27 of metal leaf advanced at a constant rate is moved at variable velocity through a rotary die stamper 6, 7 such that between stamps the metal leaf moves at a velocity which is slower than the velocity of a substrate web 28; but just prior to stamping the metal leaf is accelerated by contact between the metal leaf sheet and a raised die 5 rotating at the velocity of the substrate web so that when the stamp occurs the metal leaf sheet is travelling at a velocity substantially equal to the velocity of the substrate web. Varying the velocity of the metal leaf sheet has the effect of minimising the distance the metal leaf sheet travels between stamps which conserves consumption of the metal leaf sheet. Separate means for accelerating the leaf sheet prior to stamping and decelerating the leaf sheet after stamping may also be provided.

Abstract: A photoconversion device comprises a plurality of cells 1 each having a bipolar type sensor element T, the base of which is connected to a reset switch FET M and is also capacitively coupled to a control electrode. The device is read out by providing a positive pulse to the base of the sensor T through the control electrode, and is refreshed by a first operation in which the base is set to a preset level through the FET M and a second operation in which the base-emitter junction of the sensor T is forward biased. A control terminal 19 provides a high level reset voltage to a main electrode region of the FET M through an emitter follower arrangement 18 to turn the FET M on for the first reset operation without providing a negative pulse on the horizontal drive line 2 which is connected both to the gate of the FET M and the capacitively coupled control electrode. This permits a relatively high voltage read out signal to be provided on the horizontal drive line 2 without subjecting the line to an excessive total voltage swing.
