Title: Improvements in or relating to the process of and means for tapping fluid pressure mains without interrupting the flow
IPC: B23B41/08
Filed: 1927-09-05
Abstract: 277,036. Odriozola y Elezgaray, J. M., (Assignee of Odriozola y Sarria). Sept. 4, 1926, [Convention date]. Drilling-machines. - A device for tapping a fluid pressure main without interrupting the flow comprises a casing for attachment to the main, the casing having two compartments separated by a valve which are adapted to be connected alternately with the pressure in the main or the atmosphere, and a second valve being provided for equalizing the pressure on opposite sides of the first valve. The casing G is attached to the main by a chain Q tensioned by nuts, a joint being made by means of a rubber ring P and a fibre sleeve O. The upper part of the casing carries a spindle A having a flanged sleeve B pinned thereto against which bears the flanged end of a screwed feeding sleeve E acting through a ball bearing C. In operation, the casing is attached to the main and a combined drill and tap is inserted in the end of the spindle A. A hole in the main is then drilled and tapped, the fluid escaping from the main into the casing as far as a gland D, and the spindle is then withdrawn into the upper compartment of the casing. A sluice valve N is next closed by an arm M operated by a crank applied at M<1>, thus cutting off the pressure from the upper compartment and allowing the spindle to be removed and the drill replaced by a valve H. On the spindle being replaced in the casing a valve L is opened to allow pressure from the main to reach the upper compartment and thus equalize the pressure on both sides of the valve N, which may then be opened to allow the valve H to be screwed into the main by the spindle A. The valve H is inserted with its plug I closed by the screwed spindle F<1>, and on removal of the casing G a lead pipe A', Fig. 4, may be attached by a yoke C<1> and screw E<1> engaging a flared end on the pipe. Alternatively, the pipe may be secured by a flanged nut screwing on the valve body and engaging a flange on the sleeve B', the latter being welded to the pipe.

Title: Improvements in machines for photographic type setting
IPC: B41B17/08
Filed: 1946-08-13
Abstract: 625,047. Photographic type-composing. NEWMAN, H. G. Aug. 13, 1946, No. 24015. [Class 98 (i)] A photographic type-composing machine comprising a series of lamps arranged to direct beams of light through a corresponding series of lenses so that all the beams converge to produce, at a common point on a sensitized film which is traversed through the machine in the intervals between successive exposures, images of a series of printing characters, equal in number to and illuminated selectively by the lamps and lenses, and arranged on a master film or plate inserted between the lamps and their corresponding lenses so that as any one lamp is lit the corresponding character is projected for a standard period on to the sensitized film, is characterised in that a light-sensitive cell is arranged to receive through an aperture or transparent portion adjacent to each character on the master film, and proportionate in size to the width of the character, a corresponding amount of light during the exposure of the character, so as to supply current to charge a condenser controlling a magnetic clutch, which charge, when released at the end of the exposure, causes the sensitized film to move through the machine a distance proportionate to the width of the character. As shown, light from each of a series of lamps A is focused by a lens B to a common point C on a sensitized film D. The printing characters are arranged on a film or plate H. Each lamp is connected to a switch E operated to close the lamp circuit for a standard time by one of a set of keys G arranged like a typewriter keyboard. Adjacent to each character is an aperture of area proportional to the width of the character, and light from this aperture falls on to a photo-electric cell J, producing a current charging the condenser K. At the end of the standard time, the key E again operates and the condenser discharges through a circuit controlling a magnetic clutch L, whereby the film sprocket M is driven by a continuouslyrunning motor F for a time proportional to the width of the character previously recorded and moves the film a distance equal to the character width. Standard signals are recorded to effect interword spacing and to indicate the end of the line. The film passes to developing, washing and fixing tanks N, O, P and is subsequently dried. A common light source may be used with a shutter for each lens.

Abstract: 245,525. Westinghouse Brake & Saxby Signal Co., Ltd., (Union Switch & Signal Co.). Oct. 10, 1924. Vacuum tubes.-In a relay of the type described in Specification 223,589. comprising a thermo-sensitive substance heated by bombardment of electrons emitted from a suitable source, the action of the electrons is controlled bv means of a solenoid producing a magnetic field surrounding the tube. In the track signalling system shown, three thermo-sensitive devices D, E, F are provided, each comprising a heating filament 19, 20, 21 energized from the points 27, 28 of the secondary of transformer TB and two separated semi-cylindrical members, coaxial with the filament, formed of metallic electrodes enclosing material such as cupric oxide, or cuprous oxide having a high negative-temperature coefficient. Devices D, E include cylindrical grid members between the filament and the thermo-sensitive members. Device F is surrounded by a solenoid 13 connected across the track rails. Each of these devices is enclosed in an exhausted bulb or tube. The device F, when the coil is de-energized, becomes active. When the section ahead is unoccupied the coil 13 creates a magnetic field which prevents bombardment by electrons of the thermo-sensitive elements and these circuits are broken down. At the same time current is supplied from the divided transformer 14 to the devices D1, E, the grids of which are energized by opposite phases of current, and consequently one is active and the other inactive, according to the phase of current in the track rails Q.

Title: Remote control receiver for central remote control installations utilising audio-frequency signals superimposed on the mains network
IPC: H02J13/00
Filed: 1957-08-01
Abstract: 820,141. Electric selective signalling. LANDIS & GYR A.G. Aug. 1, 1957 [Sept. 27, 1956], No. 24469/57. Class 40 (1). A receiver for a remote control system of the kind using audio-frequency signals superimposed on the mains network Q has a synchronously-moving selector switch arm w, Fig. 2, a relay R energized by the incoming control pulses through a frequency-responsive circuit EK and, in series with the contact r of this relay, a controlled auxiliary contact h which makes after and breaks before the contact r so as to protect the latter against undue wear. The switch arm w is driven by a synchronous motor Sy which is started by a start pulse ST, Fig. 1. Subsequent pulses B in the cycle cause contact r to close while the arm w is in contact with corresponding studs S to energize relay coils K 3 , K 4 , &c. These coils are arranged in pairs and displace switches k 3 , k 4 , &c. to alternative positions. The auxiliary contact h, which may be much more robust than contact r, is driven by a cam from the synchronous motor Sy and closes for short periods th shown in line D 3 . The switch arm makes contact for periods t w  shown in line D 2 . The load current is therefore switched on and off by contact h, the length of life of contact r being increased accordingly. In the form of Fig. 5, the auxiliary contact h is replaced by contacts h 3 , h 4 , &c., in the circuit of each control coil K 3 , K 4  which are single-coil change-over relays. The contacts h 3 , h 4  transfer when the coils K 3 , K 4  are energized and make contact with the alternative stud, thereby interrupting the coil current. The current is therefore switched on by the relay contact r (which is the less damaging of the two operations) and is switched off by the relay contacts h 3 , h 4 , &c. Furthermore, on repetitive orders, occurring in subsequent cycles, there is now no circuit through the coils K 3 , K 4 , &c. so that no current passes when the contact r makes.
