Title: Isolator for smoke detector
Inventor: HASAN OSMAN
IPC: H01R9/00
Filed: 2009-11-23
Abstract: An electrical isolator, for instance for a mains-powered smoke detector, includes a housing 114 containing a circuit board 102. The circuit board includes connectors for connection to a mains supply and to a smoke detector, and also an indicator lamp and a switch 108. When the switch is off the smoke detector is electrically isolated from electrical power and the indicator lamp is extinguished, and when the switch is on the indicator lamp is lit and power is provided to the smoke detector. The isolator also includes a light unit 128 attached to the housing with electrical connection to the mains supply and to a light bulb 126. The lighting unit and the circuit board are connected to the mains supply in parallel, so that when the switch is off the electrical connection of the lighting unit to the mains supply is unaffected. Thus if the smoke detector is defective, the switch can be turned off causing current to cease to flow to the smoke detector and the indicator lamp will extinguish, indicating that it is now safe to work on the smoke detector. The light bulb will remain on, creating an easier working environment.

Filed: 1932-04-07
Abstract: 383,532. Rolling. COLD METAL PROCESS CO., 1200, City Bank Building, Youngstown, Ohio, U.S.A. April 7, 1932, No. 10017. Convention date, May 4, 1931. [Class 83 (iv).] Coldrolling.-The ratio of the velocities of the material entering and leaving the pass of a rolling-mill is measured to indicate the degree of reduction produced, alteration in width being assumed to be negligible, any adjustment of the pass required thus being determined. Reels 3, 4, Fig. 1, are positively driven and are controlled by a lever 5 to pass the material through the rolls 9 alternately in each direction. The material passes over cooling sheaves 6, 12, wipers 7, and a guide 8. Backing-up rolls 10 are carried in bearings 11, the upper being carried in casings 13 balanced by springs 14, and adjusted by wedges 15 from handwheels 16, 17. Extensions 18, 20 of the shafts carrying the cooling sheaves, support fast and loose pulleys 19, 21 and 22, 32, the loose pulleys being driven by crossed belts 30, 33 respectively. Spiders 25 support rollers 26 which are urged into engagement with the inner faces of the pulleys by springs 34. Indicators 27 cooperating with scales 28 are connected to the spiders. The belts 30 or 33 are placed in grooves in the pulleys such that when the desired degree of elongation is produced, the pulleys 22, 19 or 21, 32 are driven with equal speeds but in opposite directions. The pass is therefore adjusted until the pointer 27 is brought to rest on the scale. Other devices may be employed to determine the elongation, such as an electric effect dependent on the absolute speed of the material. The speed of the rolls may be assumed to be proportional to that of the material leaving the mill. Specification 292,494, [Class 83 (iv), Metals, Working], is referred to.

Filed: 1942-07-21
Abstract: 556,726. Resistance coatings and deposits; casings and shields ; cooling, inductance measurements. SMITH, S. J. July 21, 1942, No. 10148. [Class 37] A resistor of low inductive reactance, particularly for use with alternating currents of very high radio frequency, comprises a disc of resistive material, a terminal at the centre of the disc, and a second terminal mounted round the periphery of the disc. A thin disc 1, Fig. 1, of resistive material is clamped around its periphery between two cup-shaped housings 2, 3 of brass, copper, &c., which are secured together by screws passing through holes 4; 5 and threaded into tapped holes 6. Tubular screens 7, 8 are screwed into the ends of the housings 2, 3. A conductor 9 makes contact with the centre of the disc 1 and passes through the screens 7, 8, from which it is insulated by insulating beads or otherwise. For resistors of low value the disc 1 may be of mica coated by sputtering or evaporation with a film of metal such as silver on one or both sides. The relatively large area of the disc and the good thermal conductivity to the housing promotes cooling. Fig. 2 shows a Q meter or circuit magnification meter in which the resistor is employed, The conductor 9 extends between a terminal 10 and through the resistor 11 and screen 12 to a source 13 of radio-frequency current. The housing of the resistor 11 is mounted on and grounded to a metal panel 14 by means of a bracket 15. A second terminal 16 is connected to the rotor of a variable condenser 17 and one terminal of a vacuum tube voltmeter 18, the stator of the condenser and the other terminal of the voltmeter being grounded to the panel 14. The inductance to be tested is connected between the terminals 10, 16. Radio frequency current of known value is passed through the resistor 11 from the source 13 and the potential difference set up across the resistor is applied in series with the inductance and the tuning condenser 17. The voltage set up across the condenser 17 at resonance is measured by the voltmeter 18, the Q factor of the inductance under test being the ratio of this voltage to the voltage injected into the circuit.

Title: Punching presses
IPC: B21D28/00
Filed: 1976-03-16
Abstract: 1485245 Punching HYDREL AG 16 March 1976 [17 March 1975] 10413/76 Heading B3W To prevent damage to a workpiece 38 and to the tools of a fluid operated punch press working unit, actuation of a switch 33 by a movable press table 9 during a working stroke before actuation of a switch 24 by a member 18 outside the press tables, due to the presence of a foreign body 32, stops the press table 9. One side 22 of the member 18 is acted on by the hydraulic pressure medium which actuates the table 9 and the other, 19, by compressed air at a constant but adjustable pressure. Instead of the piston 18 shown, the movable member may comprise a diaphragm. The tools comprise a punch 6 with ejector 7 and a die 8 with a perforating punch 12 and an hydraulic ejector 11. In operation of the press, compressed air is supplied via regulator 27 to chamber 19 at a higher pressure than the hydraulic fluid supplied via lines 36, 15 to raise the table 9, keeping a stop 23a on the member 18 in engagement with the switch 24. A cam 34 on the table 9 is set to actuate the switch 33 shortly before the die 8 engages the workpiece 38. The increase of pressure in lines 36, 15 on clamping of the workpiece between the die 8 and punch 6 causes the piston 18 to rise and thus actuate the switch 24. Were a foreign body 32 present, the piston 18 would be moved to actuate the switch 24, due to increased pressure, before the cam 34 tripped the switch 33 and the press table 9 would be moved away from the workpiece. Engagement of a pin 31 with the workpiece 38 at 30 due to too short a feed step has the same effect as the presence of a foreign body.
