Title: Method and system for pneumatically transporting containers
IPC: B65G51/10
Filed: 1973-02-09
Abstract: 1423305 Pneumatic container transport INSTITUTUL PENTRU CREATIE STIINTIFICA SI TEHNICA 9 Feb 1973 [31 March 1972] 6485/73 Heading B8A A pneumatic container transport system comprises a plurality of successive tubular stages each having an operable closure at its downstream end, means to pump air from each stage and means to move each closure to an open position as a container approaches it. The system indicated in Fig. 1, comprises a series of tubes 11, each open to the atmosphere at the upstream end and sealed with an openable closure 5 at the downstream end. A container entering the tube seals the upstream end so that the suction produced by exhausters 4 at suction chamber 2 of each tube stage draws the container along the tube. At electromagnetic control block 8, the container completes an electromagnetic circuit to open the closure 5 via cables 24. As the container passes suction chamber 2, it blocks the suction and the container moves forward under its own inertia, compressing the air ahead of it until atmospheric pressure on both sides of closure 5 assists the opening of the closure. The container passes on into the next tube stage, having reached an initial speed, to be conveyed through this stage in the same way as through the previous stage. Closure 5 closes as soon as the container has passed due to the depression in the tube caused by exhauster 4 and due to spring force on cables 24. The tube stages are also provided with rollers at regular intervals along the bottom and sides of the tube to assist transport by reducing friction.
Patent GB-375435-A (GB)
Title: Improvements in apparatus for the display of advertisements or the like
IPC: G09F23/16
Filed: 1931-12-03
Abstract: 375,435. Changing - signs. HULSE, A., 13, Wallwork Street, Higher Openshaw, Manchester. Dec. 3, 1931, No. 6528. [Class 3 (i).] An endless spring-driven display band is controlled by the spring motor of a clock so as to move intermittently. The mechanism comprises a disc 21 furnished with equally-spaced circumferential pins 22 and rotated continuously by the clock spring 16. The pins 22 engage the heel of a plate 24d fixed to a rocking lever 24 pivoted at 23 and counterbalanced at 27. The other end of the lever 24 has a fixed pawl 24b engaging ratchet teeth 37a on a pinion 38 in the band-driving clockwork train 31, and a flat projection 25 which can come against two pins 42, 43 spaced radially and circumferentially apart on another pinion 41 in the clockwork train 31. In action, the lever 24 is raised against gravity by a pin 22 to free pin 42 thus allowing the train 31 to start. A tooth 37a engages the pawl 24b to lift the lever 24 sufficiently high to meet the pin 43 and stop the train 31. The pin 22 then clears the plate 24d and allows the lever 24 to drop from the pin 43 and the clockwork 31 to rotate till the pin 42 again abuts against the end 25, thus stopping the display band after it has moved the requisite amount to change the display. The band rollers may be adjustable to tension the band, or the band may be of elastic material.

Title: Improvements in or relating to valve systems
Inventor: THOMPSON HERBERT GEORGE GORDON
IPC: A62B13/00
Filed: 1954-03-05
Abstract: 834,799. Ventilators. MINISTER OF WORKS. June 6, 1955 [March 5, 1954], No. 6584/54. Class 137 [Also in Group XXIX] A chamber is isolated from the effects of extraneous impulsive waves occurring in an atmosphere 2 with which the chamber normally communicates through a duct 1, by a labyrinth 3a, 3b, 3c arranged to form part of the duct and through a valve 13, 16 associated with the duct 1, arranged so as to be directly responsive to pressure waves occurring in the atmosphere 2, the valve being operative to effect closure of the duct between the labyrinth and the chamber before the pressure wave can affect conditions within the chamber. Normally air passes through non-coincident holes 16a and 13a in a movable and fixed valve plates 16, 13 respectively, these holes being closed when sudden pressure at 8 forces a cap 9 to slide down on 3b and move valve plate 16 against a spring 17. An additional valve plate may be arranged to close on suction Fig. 3 (not shown). The labyrinth may serve a plurality of chambers each through a duct 21, a valve 30 and a further duct 22, Fig. 6, the valve 30 being actuated directly by atmospheric pressure wave at 27 before a pressure wave can reach the duct 21 through the labyrinth. A switch 37 may be actuated by movement of the rod 33 and electromagnets may be employed to hold the valve open or closed or to return it to the open position. When the apparatus is employed in the ventilation of an air raid shelter it stops the transmission of a blast wave, alternatively it may safeguard chambers from the effects of detonation waves of explosions in mines and power stations or may effect sealing in jet propulsion units in response to impulsive pressures.

Fig. 2 shows the glass cylinder 1, reflector 3, lamps 11, fan 7, and a band and roller arrangement 11<1>, 12, which permits insertion of printing material at 15 and withdrawal of it at 16.
Patent GB-287167-A (GB)
Title: Improvements in or relating to alternating-current electrical generators
IPC: H02K19/20
Filed: 1928-03-02
Abstract: 287,167. Lorenz Akt.-Ges., C. March 18, 1927, [Convention date]. Inductor-alternators; rotary converters.-In an alternating-current inductor generator operating on the homopolar principle, the pitch of the generating winding is equal to a fraction of half the pitch of the inductor teeth, and the coils of the winding are so connected in series that a frequency higher than that corresponding to the inductor tooth pitch is generated. The method of operation is explained with reference to Fig. 1 wherein the direction of the flux is represented by the dotted arrows, and the coils are assumed to be wound in consecutive pairs of stator slots n1.- n2, n3-n4, &c., and therefore the coil pitch equals one half of the tooth pitch of the inductor. To obtain currents of higher frequency, the stator slot pitch is decreased, i.e. for triple frequency a stator slot pitch of one third of half the rotor tooth pitch is adopted as shown in Fig. 2. Fig. 3 shows the invention applied to a machine generating currents of three different frequencies for telephone signalling purposes. The armature winding Wa of a continuous-current motor is connected to slip-rings s from which current having a frequency for example of 25 may be obtained. The pole shoes of the poles N, S are provided with a winding W150 giving a frequency of 150, and a second winding W450 giving a frequency of 450. The pitch of the winding W150 is equal to half the armature tooth pitch as in Fig. 1, and the pitch of winding W450 is equal to one third of half the armature tooth pitch. A greater, number of currents of different frequencies may be generated in a single machine. One or both slip rings may be dispensed with and the spindle or one of the commutator brushes may be used for taking off the low frequency current. One of the higher frequency windings may be located on one pole face and the other winding on the other pole-face and the winding arrangement N1-N2, N2-N3, N3-N4 &c. may be adopted, successive coils being oppositely wound.

Title: Apparatus for indicating the rate of flow of a fluid
IPC: G01F1/10
Filed: 1955-03-07
Abstract: 799,773. Electric fluid flowmeters. HOBSON, Ltd., H. M., and FELLOWS, H. Dec. 21, 1955 [March 7, 1955], No. 6680/55. Class 40 (1). The rate of flow of liquid in two conduits 12, 12A (Fig. 3) is determined individually by flowmeters 10, 10A, each comprising a vaned rotor 11 carrying a magnet 13 which produces a pulse in a solenoid 14 for each rotation of the rotor, each series of pulses being amplified at 15 and shaped at 16 to actuate a monostable flip-flop circuit at 17, so that the average anode current of the normally non-conducting valve of the flip-flop is a measure of the rate of flow, the two currents, one for each flowmeter 10, 10A, flowing through a common meter M which therefore indicates the total rate of flow. The shaped pulses from 16, 16A are also fed through a gating circuit 19 to a binary frequency dividing chain 21-21n to actuate a counter 18 which therefore indicates the total liquid flow. Speci. fications 752,496 and 798,507 are referred to.

[Also in Group XXII] A method of making and metallizing a fluid tight container of sheet steel comprises assembling half-shells 1 and 2, a base 5 and a valve body 4 with copper brazing rings 2<SP>1</SP>, 8 and 7 and passing the assembly through a tunnel furnace which has a reducing atmosphere and which has temperature zones to effect brazing, metallizing and annealing. The assembly is supported on a spindle 10 which carries it through the furnace. Fig 1 shows the relationship between furnace temperature (ordinates) and time (abscissae). The part B-C represents a time interval of one minute and a temperature of 1120‹C. this is followed by cooling to 850‹C. over a period of 17 minutes, soaking for 5 minutes (D-E) and then heating in three minutes (E-F) to 920‹C, which is the annealing temperature and maintaining this temperature for five minutes. The containers leave the furnace at a temperature of 300‹C. It is characteristic of the invention that the annealing temperature is reached after a period of rising temperature and not falling temperature. The metallizing compound which comprises powdered bronze 70-80%, powdered iron oxide 10-15% and a binder 5-10% is applied by known means and in this case becomes molten at the brazing temperature. Alternatively the metallizing compound may have a melting temperature less than the brazing temperature but higher than the annealing temperature.

Oil switches; switchboards. - In ironclad switchgear the connections between the oil switch contacts and the feeders, bus-bars &c. are in the form of removable plugs which are inserted individually through openings in the armouring to engage corresponding socket members. As applied to a three-phase truck type switch gear unit Fig. 1, the stationary member comprises three chambers 12, 13, 14, the lower of which serves as an entry for the feeder 26 and the other two as housings for alternative sets of bus-bars 24, 25. The cores of the cable 26 are connected to socket contacts 17 held in insulating tubes 11, each bus-bar being joined to a socket 15, 16 within tubes 9, 10 in the corresponding chamber. The movable truckmember carries an oil switch 1 with hood 2 through which pass corresponding insulating tubes 6, 7, 8. Within these tubes are annular contacts 34, 35 in connection with the oil switch contacts 27, 28 respectively. Removable plugs 29 are adapted to be inserted in the openings in the hood 2 to bridge socket contacts therein and so permit the feeder 26 to be connected by the switch 1 to one or other of the sets of bus-bars 24, 25. To prevent both sets of bus-bars being alive simultaneously hinged flaps 35 are provided to cover one or other sets of socket holes. Each plug has an insulating handle 30 enabling it to be withdrawn without first removing the truck. To prevent withdrawal of the plugs while the switch 1 is closed a plate 32 is held against them by a projection 33 on the switch operating shaft 34. The plug members may be modified to earth parts of the gear or to lead current from the bus-bars &c. to testing instruments. Where it is desired to break contact between the plug and socket members under an <*> insulating liquid, their axes may be suitably inclined so that the sockets form oil receptacles. It it is desired to change the bus-bars connection without interrupting the supply, the interlock between the plugs and switch is omitted, and a switch for temporarily interconnecting the two sets of bus-bars is provided.
