Abstract: 1,028,590. Froth flotation apparatus; mixing and agitating apparatus. KLOCKNER-HUMBOLDTDEUTZ A.G. Feb. 5,1964 [Feb. 21,1963], No. 4872/64. Addition to 959, 920. Headings B1C and B2H. The swash plate impeller of the froth flotation chamber described in the parent Specification is modified by the provision of ribs on its underside as well as its upper side and by providing a supply of air to both sides of the plate. As seen best in Fig. 3 the plate rotates in a cage between plates 28 and 29 with an encircling array of baffle ribs 30 to break up air bubbles. The hub 23 on which the plate is mounted provides air channels between radial fins 24 so that air drawn down from the air supply pipe 34 is not only distributed over the top of the swash plate but is drawn also underneath the plate. The float fraction is collected in launders 40 from over weirs 35. The weirs are made of rubber supported by adjustable links 36-38. Two such impellers may be at work in a single chamber and three such chambers be arranged in series as divisions of a single trough. The underflow outlet may be controlled by a needle valve.

Title: Material process chamber seal - has a convex wall with inlet covered by a continuous flexible belting
IPC: F16J15/16
Filed: 1974-12-16
Abstract: An appts. is claimed to seal a process chamber, where web or sheet material is passed into a chamber where the pressure is different from ambient pressures or conditions, with one chamber wall given a curved convex profile and provided with a slit for the material to be processed to pass into the chamber.

IPC: H04N7/00
Filed: 1983-11-18
Abstract: Cable television network comprising a number of exchanges by means of which program signals received through a bus are transmitted through subscriber lines to subscriber stations connected to the respective exchanges. At least one of the program signals is a teletext program signal consisting of a cyclically repeating series of a number of coded information pages of arbitrary contents each having a page number code. The teletext signal is modulated into the frames of a standard television signal and the pages can be selectively displayed separately in a subscriber station, for which purpose each subscriber station comprises selection means for generating a page selection signal which is transmitted through the subscriber line to a circuit in the exchange by means of which the page corresponding to said page selection signal is selected out of the teletext program signal and is stored into a memory. Thereafter said page information is continuously modulated onto the frames of a standard television signal and transmitted to the subscriber station from which the page selection signal originated.

Title: Tennis ball
IPC: A63B37/06
Filed: 1992-07-27
Abstract: A pressure-free tennis ball is filled with a foam material. This prevents the ball being excessively depressed when hit hard, which gives rise to arm injury. The layer of felt can be applied to the foam material with or without a layer of rubber between them. The increased stability makes it possible to reduce the thickness of the rubber wall compared to that of the standard tennis ball.
Patent NL-9300205-A (NL)
IPC: G02B6/12
Filed: 1993-02-02
Abstract: An integrated optical, polarization-manipulating device, comprises a first waveguiding section (A) with a first guide (21), a second waveguiding section (E) with a second and a third optically decoupled and physically separated guide (26, 27) and an intermediary waveguiding section (C) for an adiabatic coupling between the first and the second sections (A, B). The intermediary section (C) comprises a polarization-sensitive asymmetric Y-branching device, provided with two mutually diverging intermediary guides (24, 25), a monomodal (24) and a bimodal (25), coupled to the guides (26, 27), respectively, of the second section. The guides (21, 27) form, with dummy guides (22, 28), respectively, polarization-insensitive asymmetric Y-junctions which function as mode converters between zeroth- and first-order guided modes. Bimodal coupling sections (B, D) provide for adiabatic couplings between asymmetric Y-junctions and the intermediary section (C). Advantages: the device can be provided on non-birefringent materials; is relatively simple to manufacture; and, in the case of the ridge-type guide structure, only one etching step is required. <IMAGE>
Patent NL-9400397-A (NL)
Inventor: HORST HANS VAN DER
IPC: B41F13/004
Filed: 1994-03-14
Abstract: The invention relates to an apparatus for printing onto a substrate printing plates manufactured from flexible material, comprising: a frame (2); a forme cylinder (15) mounted in the frame and adapted to receive the printing plate (16); a counter-pressure cylinder (27) mounted in the frame; guide means for carrying the substrate for printing between the forme cylinder (15) and the counter-pressure cylinder (27); drive means for driving the forme cylinder and the counter-pressure cylinder, wherein the drive means are adapted to drive the forme cylinder and the counter-pressure cylinder at a different peripheral speed. Assuming the situation where the forme cylinder is driven at the nominal speed and the flexible printing plate is intended for a forme cylinder with a smaller diameter, the flexible printing plate is fixed on the proof printing machine on a cylinder with a large diameter; stretching of the image of the flexible printing plate for printing is thus less than that taken into account in the manufacture of the flexible printing plate. In order to compensate this the counter-pressure cylinder is driven at a higher speed so that the substrate on which the proof must be made moves more rapidly, whereby the too small stretching of the image of the flexible printing plate for printing is compensated. <IMAGE>
