Title: Manufacture of ultramarine
IPC: C09C1/32
Filed: 1946-07-05
Abstract: Primary ultramarine is produced by forming the ultramarine mix into briquets and placing them in a refractory container in which they are fired.  The briquets, which preferably have a density of at least 1.2, may be made by pressing in a mould or, when a binder is used, on a roll press.  Water may be used as the binder, in which case the briquets must be dried immediately.  Other binders include oil such as kerosene and water-soluble materials, preferably mixed with water, such as glutrin and sodium silicate. Alternatively, the mix may form its own binder by heating to the melting point of sulphur.  The examples describe mixtures containing dried china clay, diatomite, soda ash, sulphur and rosin.  Specification 617,523 is referred to.

Filed: 1974-05-08
Abstract: 1474595 Sheet ordering apparatus DEAN RESEARCH CORP 8 May 1974 20240/74 Heading B8R Sheets moved along a table 10 by driven rollers 12 are directed to selected outlets 14 at the sites of the table by orienting groups of the rollers to displace the sheets laterally, Fig. 2. The rollers may be oriented by solenoid or pneumatic means which are controlled from a computer. Sensors 18 (photoelectric or pneumatic) sense the position of sheets on the table and feed the information to the computer. For handling a row of sheets 62, Fig. 8, leaving a belt conveyer 64 a lateral separation unit 60 may be provided. Rollers 66 of the unit are orientable in the manner of rollers 12 to separate the sheets laterally of the conveying direction before they reach the table 10. Detectors 70 sense the presence of a row so that orientation of the rollers 66 occurs at the right moment. To compensate for lateral shift of conveyer belt 64, sensors 74 detect the shift and feed information to the computer which then adjusts the orientation of rollers 66 to take account of the shift. The output stations may be provided with means to sense when they are full and the computer may be programmed to route sheets to alternative outlets. A faulty sheet sensor may be provided and such sheets may be routed to a reject station. The individual rollers 12 may be driven from shafts 24 via belts 46 and 48 and piston (or solenoid) activated rods 30 may move rods 56 to turn the roller supports 36 through the required angle.

Title: Improvements in or relating to machines for making glass bottles or other hollow glassware
IPC: C03B9/22
Filed: 1936-08-24
Abstract: 480,741. Glass manufacture. EVANS. W. E. (O'Neill European Machine Co. of Montreal) Aug. 24,1936, No. 20261 /37. Divided application. [Class 56] Relates to a machine for forming glassware in which the parison moulds are charged with molten glass by suction, and in which each mould rocks about an horizontal pivot when dipping to gather glass, as described in Specification 315,154, [Class 56]. According to the invention, the dipping-cam comprises a pivoted section which is operated automaticaJly by pneumatic piston to stop the machine, and to prevent the moulds from dipping, if any obstruction should increase the load on the driving- mechanism. The parison moulds P rotate about a central column 27. and each mould support is rocked about an horizontal pivot 83, to dip the mould into the glass G in a forehearth F, by a stationary cam 45 which engages a roller on an arm 84 on the mould support. The cam 45 includes a hinged section 177 which when raised, as shown in dotted lines. prevents the moulds from dipping into the glass. The section 177 is connected by a lever 180 with the piston rod of a pneumatic cylinder 187, which is connected by a pipe 189 and a valve 191 with a supply of compressed air. The valve 191 is operated by an electric solenoid E connected by leads 193 with a junction box 194. This box is provided with a starter switch 195 and is connected by leads 201 to the driving-motor 159, and by leads 196 with a limit switch 197. The motor drives the machine through a shaft 162 which includes a telescopic section 164, and a coiled spring 165 introduced between flanges 166. The spring closes two members 168 of a clutch which are provided with interengaging conical teeth. An arm 198 on the switch 197 engages the movable member of the clutch. In operation, if the rotation of the mould tables is resisted, the force of the motor causes the separation if the two clutch members 168, and this actuates the switch 197 which disconnects the starter switch 195, thereby stopping the motor 159. The valve 191 is opened, also, and admits air to the cylinder 187. The cam section 177 is thus moved upwards and prevents the moulds from dipping into the glass. A valve 192 operated by hand, and a pipe 190 byepassing the valve 191, enables the cam section 177 to be raised while the machine is running.

Title: Apparatus for playing games of skill
IPC: F41J5/052
Filed: 1923-08-11
Abstract: 221,927. Spear, A. E. Aug. 11, 1923. Outdoor games. - Apparatus for playing games of skill comprises a number of displaceable plates or targets hinged to a framework, and means adapted to register a score when any of the displaceable plates are struck by a ball delivered by a player. The apparatus consists of a framework 1 formed into compartments each containing a plate 2. The plates are hinged along their lower edges 3 to the framework and normally rest in an inclined position, as shown in Fig. 2, with their upper ends against stops 4. A ball is projected at the apparatus by a player, in some cases by being struck by a racket over a tennis net arranged at a suitable distance in front of the apparatus, and a plate 2, if struck with sufficient force, swings backwards and operates a bell-crank lever 20 to lift an indicating-plate 23 above the framework. The plates may be made of transparent material and an electric lamp 6 may be arranged behind each plate. A plate when struck may close contacts 15, 17, in the circuit of the lamp, thus causing it to light. The lamps are in circuit also with other lamps arranged on a separate scoring-board. If the plates are not struck with sufficient force, only the contacts 15 will be closed and the lamps will be lighted intermittently since the contacts are broken as the plates fall back to their normal position against the stops. The device is thus a measure of the strength as well as the accuracy with which the ball is delivered.
