The conveyer is formed by stub-rolls. A glassbending lehr 190 and a tempering station 200 <PICT:0940210/C1/2> <PICT:0940210/C1/3> may be located beyond said spraying station 130 (Fig. 4). Glass laden moulds 100 heated in a furnace 124 pass into spraying station 130 where the glass sheet is sprayed from gun 132 which follows an arcuate path as a result of the cam means.  Then the moulds 100 pass into a bending furnace 190 and then a tempering station 200. The periods of time the moulds 100 are in the various stations are determined by electrical circuits actuated by elements responsive to the surface temperatures of the glass sheets.  When the treatment in a certain station is complete a circuit is set up which sets off the necessary steps for the continued passage of the moulds 100 through the apparatus.  The metal oxide coatings may contain tin, indium, cadmium, antimony, bismuth, iron, zinc, copper, vanadium, chromium, manganese, cobalt and nickel oxides.

Title: Process for preparing aldehydes, ketones and acids corresponding to the aldehydes from commercial crude olefines
IPC: C07C45/35
Filed: 1962-11-23
Abstract: Aldehydes, ketones and carboxylic acids are produced by oxidation of an olefinic hydrocarbon which contains acetylenic and dienic compounds as impurities by treating the mixture with hydrogen and a solid hydrogenation catalyst at elevated temperature and superatmospheric pressure to partially hydrogenate the impurities and then treating the resulting gaseous mixture with oxygen in a neutral to acid aqueous medium in the presence of a catalyst comprising a salt of palladium, iridium, ruthenium, rhodium or platinium and an inorganic salt of a metal capable of having several valency states. The two steps of the process may be carried out at the same temperature and pressure, e.g. 100-120 DEG  C. and 10 atm. gauge). The products are mainly aldehydes and ketones and the aldehydes may be further oxidized to give the corresponding carboxylic acids. Examples are given of the treatment of ethylene, propylene and butenes which contain dienes and acetylenic compounds as impurities.

Title: Spectrophotometer
IPC: G01J1/36
Filed: 1961-12-14
Abstract: 943,165. Vibratory electric motors. BECKMAN INSTRUMENTS Inc. Dec. 14, 1961 [Aug. 18, 1961], No. 44724/61. Heading H2A. [Also in Division G1] The invention relates to an electromagnetic device for vibrating an oscillating structure of a photo-electric spectrophotometer of the type described in Specification 753,890. A frame 32 of the structure (Fig. 2, not shown), has tabs 37, 38 securing a horizontal strip or armature 39 of silicon steel, the centre of which is encircled by a coil 44. Adjacent the ends of the strip 39 are two permanent magnets 47, 48 shaped and positioned as shown, and when an alternating current having a frequency equal to the natural frequency of the structure is fed to the coil 44 the strip oscillates between them in the horizontal plane causing the structure to oscillate. Adjustably mounted on the tab 38 is a vane 42 interposed between a lamp 53 and a photo-electric element 57. The lamp 53 is enclosed in a container (Fig. 3, not shown), having an aperture aligned with an aperture in an enclosure of the element 57 and the vane is mounted relative to the apertures so that a beam from the lamp 53 is blocked from the element 57 by the vane when the structure is in one of its extreme positions and becomes gradually unblocked as the structure moves to its other extreme position. A vane 41 similarly mounted, relative to a lamp 62 and a photo-resistive element 63 unblocks the beam from the lamp 62 to the element 63 only when the structure is at its second extreme position, i.e. the position where a large portion of the radiation from the lamp 53 falls on element 57. The signals from the photoresistive elements are fed to an electronic circuit (Fig. 5, not shown), which controls the current flowing through the coil 44. Initially, small fluctuations of the oscillating structure are sensed by the element 57 and amplified by the circuit causing the coil 44 to increase the amplitude of the oscillation. When the structure has reached a desired maximum amplitude of oscillation, the element 63 is exposed and the signal therefrom reduces the signal from the element 57 thus reducing the current in the coil. The arrangement ensures that the energy supplied by the coil is just enough to maintain the structure in oscillation.

Filed: 1973-09-28
Abstract: 1445375 Automatic voltage control HITACHI Ltd 28 Sept 1973 [29 Sept 1972] 45556/73 Heading G3R A circuit for controlling the voltage supplied by an A.C. generator includes a thyristor connected across the generator output coil and means for sensing both the load voltage delivered by the generator and the terminal voltage of a battery connected to the generator through a rectifier. As shown in Fig. 3, a battery 3 is charged over a rectifier 2 from a magneto armature coil 1 which also supplies a lamp 6 when a switch 7 is closed. In this condition, the voltage at the lamp is detected by a circuit 11-15 which turns on a transistor 10 to trigger a thyristor 8 and thus control the voltage supplied by the generator. At the same time, the current flowing through diode 11 turns on a transistor 19 to prevent current flowing through a diode 20 to the transistor 10. When the switch 7 is open, no current flows through diode 11, and transistor 19 is blocked, so that transistor 10 and thyristor 8, are now controlled in accordance with the voltage at the battery 3 sensed by voltage divider 21, 22 and Zener diode 23. The arrangement prevents over-energization of the lamp 6 and over-charging of the battery 3. In a modification, Fig. 5 (not shown), resistor 21 is connected to the anode of diode 2 to prevent charge leaking from the battery. Transistor 10 may be replaced by an additional thyristor, Fig. 8 (not shown).

Title: A process for reducing the free chlorine content of a brine
IPC: C07C17/12
Filed: 1965-10-28
Abstract: Free chlorine concentration is reduced in a brine containing it by contacting the brine with a fluid hydrocarbon at a temperature of 50-100 DEG  C.  A major proportion of the chlorinated hydrocarbon may thereafter be separated from the brine.  By the term brine an alkali metal chloride solution is intended.  A major proportion of the free chlorine in the brine may initially be removed by vacuum distillation and the brine, whose salt content may be relatively low, may be obtained from alkali metal chloride electrolysis by the mercury process.  The fluid hydrocarbon may be unsaturated aliphatic hydrocarbon such as ethylene, propylene or acetylene, a saturated aliphatic hydrocarbon such as methane, ethane, propane or butane, an aromatic hydrocarbon such as benzene, mixtures of hydrocarbons or residual gases containing hydrocarbons.
