Title: Prepayment meter
IPC: G07F15/12
Filed: 1934-03-22
Abstract: 428,724. Prepayment meter mechanism. ELECTROMAT GENOSSENSCHAFT, 79, Bahnhofstrasse, Z³rich, Switzerland. March 22, 1934, No. 9052. Convention date, March 16. [Class 27] In a coin-freed metering mechanism allowing the delivery of a quantity of electricity for a measured time and particularly applicable to current consuming apparatus, such as radio apparatus, or to the devices described in Specifications 350,944 and 405,468, coins are inserted through a slot 2, Fig. 1, to a shoot 1, the slot 2 being adjustable at will by the operator to take coins of different denominations, such as shillings or half-crowns. The coin in its passage down the shoot 1 trips by weight a lever 31 to close a switch 36 in the feeder circuit for the radio or like apparatus for a predetermined time. The upper end of a lever 3 pivoted at 4 adjusts the size of the slot 2, the lower end having a projection 8 to adjust the size of the shoot 1 opposite the lever 31. The lever 3 controlled by a spring 5 is moved by an eccentric 6 connected to a handle 7 which can be adjusted by the operator to positions I or II. When the handle is in position I the size of the slot 2 is decreased and the projection 8 is moved into the shoot. When the lever 31, arranged on a spindle 29, is moved by a coin, it moves, by a pin 30, a lever 32 to withdraw a nose 45 on this lever out of the path of a pin 46 on a gear wheel 26 in a train of gearing connecting the sun wheel 15 of an epicyclic mechanism 14, 15, 16 to a retarding vane 28, a shaft 18 of this train carrying a notched disc 20. The nose 39 of a third lever on the spindle is moved, against the action of a spring 37, out of one of the five notches on the disc 20. The gearing 15-28 is rotated by a spring 17, previously wound, until the nose 39 engages the next notch, whereon the nose 45 again moves into the path of the pin 46 and stops the wheel mechanism. The wheel 26 makes one revolution when a shilling is used. When the handle 7 is moved to adjust the slot 2 to take a half-crown, its lower wedge-shaped end moves a disc 21 axially against the action of a spring 22 to cause four axial teeth 43 on this disc to fill four notches in the disc 20. A half-crown must now be inserted to free the mechanism, but the disc 20 makes one revolution before the nose 39 can re-engage a notch, so that the wheel 26 is freed for five revolutions. When the sun wheel 15 is rotated by the spring 17, the planet-wheel cage 16 is set forward and rotates a disc 34 having a pin 35 to close the switch 36. After the wheel 26 is locked, a Ferraris or other motor winds up the spring 17 and rotates the other sun wheel 14 to return the planet-wheel cage 16 and disc 34 to their initial position thereby opening the switch 36.

Title: Improvements in or relating to the distillation of oil-bearing minerals
IPC: C10G1/02
Filed: 1950-04-14
Abstract: 672,419. Distilling oil shale &c. STANDARD OIL DEVELOPMENT CO. April 14, 1950 [June 16, 1949], No. 9281/50. Class 55 (i). Oil shale, oil sands, tar sands, &c. are distilled as a fluidized bed in a retort 10 by the heat of solid residues returned through a line 12 from a combustion chamber 40 in which they are burnt as a fluidized mass at substantially higher temperature. In starting up, non-disintegrating solids such as sand, spent oil shale, clays, siliceous cracking catalysts &c. of particle size distribution suitable for fluidizing are built up as fluidized beds in both zones and circulated whilst being heated by an auxiliary heat supply until distillation temperature of about 900- 1200‹ F. is reached, whereupon feed of coarse raw shale from hopper 1 is commenced. The shale rapidly disintegrates during distillation to fluidizable particle size. As the amount of spent shale increases extraneous fuel gas supplied with air through a line 30 may be cut down and eventually discontinued, and excess material discarded through a line 54 in addition to the withdrawal of fines through a line 45. The initial combustion of fuel, which may also be supplied through a line 33, may also be effected in retort 10, or circulation may be started only after the combustion chamber charge has reached the required temperature. Heat may be supplied indirectly by hot flue gases or otherwise.

Abstract: 200,164. Guest, J. J. April 1, 1922. Testing, balance of rotary apparatus. - Static and dynamic balance of a rotor are effected simultaneously by providing the rotor with two flanges or planes for attachment of compen. sating masses and supporting the rotor on a frame adapted to rock about an axis in one of these planes while experiments are conducted to determine, the necessary compensating masses at the other plane. The rotor G has two flanges H, J and is supported. on brackets E, D wh;ch can slide paxallel to the axis of the rotor on a support A which is mounted on a knife, edge B in the plane of the flange H. The rotor is adapted to be driven through a flexible coupling K from a variable-speed balanced motor F. The amplitude and phase of the vibra- 'tion are determined by an optical lever device and an electrical method respectively. A mirror L is hinged to the frame A and is held against the adjusting screw N by a spring M. A beam of light from a slit P is thrown on the mirror and refieded to a focus on a scale Q. The range of movement of the image of the slot is read on the scale Q and gives the mass-radius of the correction. The. phase is obtained in the, following manner. A flange R on the. shaft is provided with an insulated rim bearing against a brush V and carrying a contact S facing a contact T on a flange adjustable by means of the handle U. When the contacts touch a spark passes at P. The contact T is adjusted until this spark is in the centre of the band cf light from the slit. For use when the period of rotation of the rotor is nearly the same as the natural period of oscillation of the table a frame D with differential gear is provided as shown. The wheel E drives a carrier f in which is a weight arranged on a nut, on a screw. The out of balance weight at J may be balanced during running by traversing the weight in the screw g by pawl j and star-wheel h. The phase is adjusted by moving the differential casing by worm gear.
