Title: Improvements in or relating to thermal storage space heaters
Inventor: BOYD DOUGLAS
IPC: C07C5/367
Filed: 1963-05-18
Abstract: 1,097,820. Thermal storage space heaters. ANDREW CHALMERS & MITCHELL Ltd. Aug. 17, 1964 [May 18, 1963], No. 19865/63. Heading F4U. In a thermal storage heater in which heat storage blocks 1 are heated by electric heating elements, an air duct 2 is arranged in proximity to the heat storage blocks with its ends open to the exterior of the heater and in which is situated a shutter 5 for controlling the flow of air through said duct. The shutter 5 is biased by a spring to its open position and is closed by an electricallyoperated actuating mechanism in opposition to said spring. The electrically-operated means may be in the form of a solenoid coil 7 and a slidable armature 8 connected to a bell crank lever 9 which operates the shutter 5. The solenoid coil 7 is electrically in circuit with the heating elements so that the shutter is closed when the storage blocks are accumulating heat. A switch or time-switch may be used to control the period during which the storage blocks receive heat from the heating elements and a thermostat may be used to control the temperature of the storage blocks. An additional thermostat may be arranged in the space to be heated to open or close the shutter in accordance with the temperature in the said space.

Title: Process for separating hydrocarbons and water
IPC: C10G33/06
Filed: 1919-08-22
Abstract: 139,417. Brown, W. A., and White, F. G. Aug. 22, 1919. Purifying liquids; separating by gravity.-A mixture of water and oil or other hydrocarbons to be separated by gravity is heated to a temperature of 215-240‹ F. under a pressure sufficient to prevent the water from boiling, the lighter hydrocarbons being allowed to evaporate and escape through a relief valve. To assict in separation, a finely-divided solid, having no chemical action on the water or the oil, such as " creamy mud," may be introduced and allowed to settle. After heating as described, the pressure is increased without increasing the temperature of the body of the liquid, preferably by heating the upper layers. An apparatus suitable for carrying out the process is shown in the Figme. The mixture is placed in the vessel 10 and heated by steam admitted to coils 11, 11<a> by valves 14 controlled thermostatically or by pressure. The light hydrocarbon vapours escape through a relief valve 16 and are condensed in a. coil 16<b>. When the separation is complete the separated liquids are drawn off by a series of pipes 21.

Abstract: 207,550. Billo, O., (Assignee of Wetter, G.). Nov. 25, 1922, [Convention date]. Stencilling.-Relates to machines for printing on fabrics, paper &c. wherein is employed a stencil prepared from a textile fabric parts of which are rendered impermeable to ink. Fig. 1 shows one form of machine in which the stencil is employed, the stencil 5 being fixed in a frame 4 and laid on the sheet 3 to be printed, which, together with a supporting cloth 2, is carried on a table 1. Ink is supplied by a roller 6 inked by rollers 7 and adapted to be rolled over the stencil. In a modification, the roller 6 is supported in vertical guides and the pattern, sheet and supporting cloth are carried on a table traversable on rails beneath the roller. In a third form, Fig. 3, the stencil is in the form of an endless band 5 passing over guide-rollers 12 and over an inking-roller 6. The sheet 3 and supporting cloth 2 are passed between the roller 6 and an impression roller 11. For multi-colour printing, several printing-sets may be arranged around the roller 11. The Specification as open to inspection under Sect. 91 (3) (a) also describes the preparation of the stencil by coating parts of the fabric with an ink-impermeable medium such as oil, and by a photographic process. It is also stated that the roller 6, in the first two forms of machine described, may be replaced by a pressure plate, ink being supplied by an ink cloth laid over the stencil. This subject-matter does not appear in the Specification as accepted.

In the form shown the member f is a bell-crank lever pivoted at f<5> and heldin the locking position by a spring f<4>. A projection f<1> engages the cam-like edge of the shutter d. The pin g<1> engages an oblique surface f<3> and rocks the member f freeing the shutter which turns into the position shown under the action of the pins g<2>. When the plug is removed the projection f<1> bears on the edge of the shutter under the action of the spring f<4> and closes the shutter. This movement may be assisted by a spring operating on the shutter. In a modification the member f has a sliding motion, the projection f<1> moving in a straight line parallel to the line joining the sockets a, b.

Class 38(3) In a double-cage mine winding installation the speed of an induction motor is reduced as it approaches the end of a winding operation by disconnecting the motor from its normal supply and connecting it to one of lower frequency. This change-over may be effected by photo-electrically operated switches which are actuated by one of the cages at a predetermined distance from the stopping station at which there are the usual limit switches. A fully automatic push-button control system for the winder may be provided, manually operated switches for each direction of travel serving to connect the driving motor to the low frequency supply throughout the entire travel of the cages for the purpose of inspecting the cable. Rotor resistance is removed in stages under the control of timing relays during the starting operation of the winder motor, switching on the motor being allowed only if the starter is in a proper condition for operation. The winder cannot be started unless the low frequency supply mains have been energized. A mechanical brake is released by means of a relay which is actuated when one of the starting switches are closed, suitable interlocking preventing the simultaneous closure of two starting switches. As a modification of the fully automatic installation operating with push button control, the starting operation may be controlled by a master drum. The timing relays take over the control of the rotor resistance if the master drum is moved too quickly.
