Patent FI-20030936-A (FI)
Inventor: VEHMAS JUKKA
IPC: C03B29/08
Filed: 2003-06-24
Abstract: The method involves conveying glass (4) through a tempering furnace so that the glass is heated from above and below. An upper surface of the glass is heated by hot air jets formed by sucking air from inside the furnace and pressurizing the hot air and recycling it back to the upper surface of the glass. Air that is taken from outside the furnace is pressurized by a compressor and heated to blow a lower surface of the glass. An independent claim is also included for an apparatus for heating glass.
Patent FI-20035022-A (FI)
Inventor: REUNAMAEKI PAULI
IPC: C03B23/025
Filed: 2003-02-21
Abstract: The invention relates to a method and apparatus for bending and tempering or heat-strengthening a bidirecdonally curved glass panel. A heated glass panel is curved in a main bending direction parallel to the advancing direction and in a sagging direction transversely to the advancing direction. Curving in the sagging direction is performed by bending conveyor rolls, the bending of which is effected by turning lever elements bearing-mounted for free rotation on the ends of the conveyor rolls. Between the outer ends of the lever elements is a push rod, whose length is quickly variable by means of an actuator.

Granted: 1960-03-22
Abstract: Polymers of unsaturated aliphatic monomers containing a vinylidene group are made by polymerizing the monomers in the presence of a catalyst formed by mixing together a vanadium compound and an addition compound of an aluminium alkyl with a diisopropyl ether. The addition compound may be preformed or added to the mixture of the vanadium compound and aluminium alkyl. The catalyst may be absorbed on to an inert finely-divided filler material.  The vanadium compound may be vanadium trichloride or oxytrichloride.  The aluminium compound is preferably tri-ethyl tri-isopropyl, tri-isobutyl, or tri-octyl aluminium.  The inert filler may be silica, carbon black, or cryolite.  The polymerization is generally effected in a hydrocarbon medium. Specified monomers are butadiene, isoprene, ethylene, propylene, and butene-1.

Title: Vaccine for cattle
IPC: A61K39/155
Filed: 1967-09-15
Granted: 1971-11-29
Abstract: Process for preparing vaccines against shipping fever in cattle by inactivating virus- and bacteria cultures with an inactivating agent. To cultures of Myxovirus parainfluenza-3 or mixtures of this with Pasteurella multocida and/or Past. haemolytica, an aluminium ion-containing agent is added having an Al-content equivalent to 10-50 ml of a 1.3% Al2O3 dispersion in water/ 100 ml culture. The agent is added before- or after combination of the 3 organisms to form one or more mixtures. The mixtures must have an optical density of 5-10 times the optical density of tube 1 on the McFarland scale, whereby the Myxovirus parainfluenza-3 and Pasteurella organisms are inactivated before or after forming the final mixture by treatment with an inactivating agent, followed by neutralisation of any excess. A parenterally acceptable antiseptic in bacteriostatic- and fungistatic amounts is then added.
Patent GB-1054058-A (GB)
IPC: H03K17/26
Abstract: 1,054,058. Transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 25, 1962], No. 41244/63. Headings H3T and H4L. In equipment, such as a transponder, in which the arrival of incoming pulses in excess of a predetermined rate could cause the equipment to function incorrectly, incoming pulses are applied via an input transistor to a diodepump pulse-rate measuring circuit which when the mean pulse rate exceeds a predetermined value periodically triggers a monostable circuit which then delivers a pulse of predetermined duration to gate the input transistor off for the duration of said pulse, so that the overall mean repetition rate of the pulses appearing at the output of the input transistor is reduced to a value at which the equipment can function correctly. Incoming negative pulses are applied to the base of a transistor Q1, output pulses being taken from its emitter. Pulses are also applied from the emitter to a diode-pump circuit comprising diodes CR1, CR2 and capacitors C1, C2, the capacitor C2 being continuously discharged through a resistor R5, so that when the repetition rate of the pulses applied thereto exceeds a limiting value (e.g. 750 p.p.s.) the potential developed across the capacitor builds up to a sufficient value to cause the breakdown of unijunction transistor Q2 so developing a positive pulse across resistor R7. The limiting value of repetition rate may be adjusted by potentiometer R3. Resistor R6 in the base-two circuit of the unijunction transistor Q2 provides temperature compensation therefor. The pulse developed across resistor R7 triggers a monostable circuit comprising reciprocally-coupled transistors Q3, Q4 which delivers a positive pulse of 15 milliseconds duration from the collector of transistor Q4 to the base of a gating transistor Q5 which thereupon conducts to short-circuit the input to transistor Q1. The greater the repetition rate of the incoming pulses the shorter will be the time taken by capacitor C2 to build up a sufficient voltage to cause the unijunction transistor to break down, so that the frequency with which transistor Q5 short-circuits the input will increase as the input repetition rate increases and the means rate at which pulses are applied to the output line will not exceed a predetermined limiting value. .

Abstract: 1,239,213. Transistor amplifying circuits. PLESSEY CO. Ltd. 12 July, 1968 [12 July, 1967], No. 31982/67. Headings H3T. A differential amplifier is operatively associated with a plurality of static switching devices which are operated sequentially for drift correction purposes. In Fig. 2, during the correction period when contacts S1 are open and contacts S2 are closed, capacitor C charges up to a voltage of approximately V REF +Ve, where Ve is the off-set voltage existing at that time. During the active period, S2 open and S1 closed, the voltage at V z  equals A v  (VS1-VS2), where AV is the gain. Thus the variable offset voltage Ve has no effect. As offset drift rates are low and capacitor time constants are high, the amplifier can perform for a relatively long time before a correction period is required. Switches S1 and S2 can be of any required static type, Fig. 3, showing the circuit in integrated circuit form using MOST's.
