Abstract: 683,118. Burner apparatus; electric lamp bulbs. BRITISH THOMSON-HOUSTON CO., Ltd. July 5, 1951 [July 14, 1950], No. 15991/51. Classes 39(ii) and 75(i) Burner apparatus, e.g. for use in depositing light diffusing silica particles on the inner surface of incandescent light bulbs as described in Specification 653,323, includes brushing means for removing products of combustion from the outer surface of a burner nozzle and comprises a burner 3 mounted on a longitudinally movable spindle 10 for movement into and out of its operative position and having means, e.g. a collar 32 secured to the spindle 10 for engaging an arm 34 of a lever 31 to tilt the latter and bring rotary brushes 4, 5 carried thereby into contact with the end and adjacent side surface of the burner nozzle. The lever 31 is pivoted to a bracket 36 fastened to a platform 13 rotatable by a gear 27 driven by a chain (not shown), the platform 13 having secured thereto a holder 9 for a lamp bulb, whereby during operation the bulb 1 is rotated relatively to the burner 3 and at the same time the brushes 4, 5 are revolved around the burner and rotation imparted thereto by the engagement with a stationary gear 39 of a pinion 38 on a shaft 40 connected by a universal coupling 42 and gearing 43, 44 (not shown), to the brush carrying shaft. A cycle of operation commences when the bulb 1 is placed on the holder 9, the burner 3 being then raised by a rotating cam 17 which lifts a pivoted lever 18 connected to the shaft 10, and which is so formed that the rate of movement of the burner 3 is slower during the upper part of its motion where a greater area of bulb has to be coated. The cam 17 subsequently lowers the burner 3 to an intermediate position where the bulb 1 is removed, and on further retraction of the burner 3 the brushes 4, 5 are brought into action in the manner described.

Title: Washing machine
IPC: D06F33/63
Filed: 1965-04-14
Abstract: 1,098,418. Washing machines. LICENTIA PATENT-VERWALTUNGS, G.m.b.H. April 14, 1965 [April 14, 1964], No. 16033/65. Heading D1A. [Also in Division F4] A washing machine comprises circular cups or bowls 1, 2 supported on outer walls 4, 3 and defining a washing chamber between the upper bowl 2 and a diaphragm 8 secured .between the bowl flanges. The bowl 2 includes a cover part 13 which is removable for the insertion of the washing, water and a washing agent into the washing chamber. The upper bowl 2 has holes 16 therein and the diaphragm 8 is also preferably provided with holes 7 or that on pressure being developed by a pump 11 the washing liquid is circulated through the holes 7 and 16 and back to the pump past a heating coil 17. The delivery of the pump is such that the. diaphragm 8 rises under the pressure developed to a position 8' to compress the washing. The pump motor is then stopped, or the delivery short-circuited, so that the diaphragm with the washing falls. The cycle can then be repeated as required until the washing operation is completed. The liquid can then be drained and the cycle repeated with rinsing water. The various operations can be programme controlled. In a modification an additional impermeable diaphragm is provided which can be subjected, by the operation of suitable valves, to pump pressure when a final squeeze drying operation is required, to move upwards together with the perforated diaphragm to compress the washing without the washing liquid flowing through the latter diaphragm. In addition warm air derived from an air pump and a heater may be delivered between the diaphragms to pass through the washing. After passing through the washing the warm air may be passed through a condenser to extract the moisture. This air pump may also be employed for the lifting of the lower diaphragm during the washing operation. In a further arrangement steam generated by a heating coil is used to lift an imperforated diaphragm having hollow beads or ridges on its upper surface provided with holes through which washing liquid or warm air can be forced to flow into the washing chamber. Pressure switches can control the generation of steam so that after compressing the washing the diaphragm returns on condensation of the steam which may be assisted by water jets.

Abstract: 205,139. Lane, C., and Hamilton, B. T. June 10, 1922. Amusement apparatus. - Relates to amusement apparatus of the kind in which the movements of a moving floor or platform are communicated to one or more cars carried by the platform. The floor comprises a series of tables A, arranged to revolve in opposite directions as far as practicable and driven from shafts S from a motor M. These shafts carry rollers R on which the tables A rotate and also bevel pinions P engaging crown wheels D arranged concentric with but independent of the tables. The drive is thus communicated to the tables through the rollers R. In a modification the tables are driven by ropes or belts engaging pulleys secured to the underside of the tables, a jockey pulley being, provided to take up slack. The moving parts of the floor may be augmented by straight-running tracks mounted on suitable guides or rollers, and the revolving tables instead of presenting a flat surface may be formed conically or have such a contour that the complete floor present a series of hills and valleys or waves. A fence limits the outward movement of the cars on the platform. The cars are preferably circular in plan and are provided with spring or other buffers F' to prevent shock. Each car is mounted on castors C having freely turning forks C<1>, and means are provided, such as a brake to each castor or a pad to grip the floor, so that a pivot may be formed around which the car can revolve to give it an erratic motion. A brake is shown in Fig. 6. The brake-block C<3> is mounted on a lever C<12> carried by the revolving sleeve C<10> and operated by a vertical rod C' passing through the stem of the fork C<1>, which are prevented from turning in the sleeve C<10> by interengaging lugs on the fork-stem and the sleeve. A spring C<5> keeps the brake C<3> normally out of engagement. Journal and thrust blocks are fitted round the sleeve C<10>. An alternative method of making a connection with the floor is shown in Fig. 7 The brakes or pads are operated as shown in Fig. 4 by a hand lever H passing through a gate H<1> in the shape of a cross so that the movement of the lever may be forwards or backwards or to either side, so operating the corresponding pad. The lower end of the rod H is pivoted at its lower end to links H<4>, R<5> and to a rod H<2> mounted in a tubular bearing H'. By the parallel linkage formed, the link H<4> moves in accordance with the movement of the lever H and engages the inner ends of the rods H<6> which are mounted on links H' and operate the bellcrank levers C<4> connected to the operating spindles C<5>. of the brakes or pads.

Title: Improved means for protecting electric lines with impedance relays
IPC: H02H7/30
Filed: 1931-06-04
Abstract: 378,574. Protective cut-out arrangements, induction relays. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. June 4, 1931, No. 16305. Convention date, June 5, 1930. [Class 38 (v).] In the protection of electric lines by means of distant relays which operate in a time dependent on the resistance or reactance of the line between the relay and the fault, the induction disc 7 which under the influence of current and voltage coils 6, 8 takes up a position dependent on the resistance is provided with an adjustable stop which limits the furthermost position of the disc so that the greatest time of action is limited and adjustable. When, in the arrangement shown, the current in the driving magnet 8 drops below a certain value and at the same time the voltage remains sufficiently high the armatures 17, 18 complete a local circuit to energize a coil 15 and release a clockwork driven contact-arm 11. The time taken by this contact-arm to engage with the cooperating contact 10 on the disc 7 and trip the circuit-breaker 2 depends upon the position assumed by the contact 10 in accordance with the resistance &c. of the line. Even for a very high resistance, however, the time is limited by the adjustable stop 19 which determines the most distant position of the contact 10, and the time is constant for all values of resistance &c. above a critical value. The shortest time of operation may be varied by adjusting the initial position of the arm 11. The constant maximum time may be graded from one relay to another along the line. With lines fed from both ends additional relays with counterrunning time graduation may be used.

Abstract: 399,449. Turbidometers. KIDDE & CO., Inc., W., 140, Cedar Street, New York, U.S.A. Aug. 25, 1932, No. 16338/33. Convention date, Nov. 11, 1931. Divided application. [Class 97 (iii).] An installation for detecting suspended matter in fluids of the kind comprising a detecting device consisting of a light-sensitive element the circuit of which is completed upon the passage of suspended matter through the device and an alarm actuated thereby, includes means for maintaining the alarm continuously actuated either upon a continued or a momentary passage of suspended matter through the detecting device. The installation includes an audible alarm and a selective visual indicator. Several fluid conduits 10 are connected to a chamber 12 from which a pipe 13 leads to a suction fan 14. A member 29 adapted to be rotated in the chamber 12 by an electric motor 16 is formed with a duct 30. As the member 29 rotates, it successively connects the conduits 10 with a pipe 31 leading to a smoke-detecting device 32 from which a pipe 36 leads to the pipe 13. The device 32 comprises a lightsource 39 and a selenium cell 41. The exhaust of the fan 14 is passed to a chamber 38 enclosing the light source, for cooling purposes. The member 29 carries a skirt 35 with indicia showing which conduit 10 is connected with the duct 30. The motor 16 drives the member 29 through a clutch 17, 18. The member 18 is adapted to be disengaged by a lever 21 actuated by an electromagnet 25. When so disengaged, it engages a brake disc 28, preventing further rotation of the member 29. Fig. 5 shows the electric circuit of the installation. The voltage fluctuations caused in the circuit of the selenium cell are imposed on the grid of a thermionic tube 46, the plate circuit 47 of which includes a relay 48. The relay 48 comprises three circuit contacts 49, 50, 51. The contact 51 closes a circuit through the winding 48 and a battery 53, so that the relay continues to be energized even though the original energizing current in the plate circuit is only momentary. Contact 50 closes the circuit 55 of an alarm bell 56, and contact 49 closes the circuit 57 of the electromagnet 25. The latter then actuates the clutch 17, 18 to arrest the member 29, so that the conduit 10 through which smoke has passed can be determined by inspection of the skirt 35. The relay 48 can be de-energized by a hand switch 54.
