Abstract: 1,271,205. Cooling shops; refrigerating. SULZER BROS. Ltd. 4 March, 1970 [5 March, 1969], No. 10501/70. Headings F4H and F4V. In a shop or a room in a shop including units 2, e.g. counters, tables, storage cabinets, display cabinets or cases, racks, cupboards and shelf units, an air cooling system supplies cooled air to outlets in the surfaces of the units, to create a cool air zone in the room up to at least head height. In the form shown, at least one air cooling device is located beneath each counter 2. Each device operates with a halogenated hydrocarbon or ammonia refrigerant and includes a fan which drives room air over a condenser and through pipes 4 to an upper zone of the room, and two fans which draw air over an evaporator and deliver the cooled air at low velocity to slots arranged around the edge of the counter. Thermostatically controlled valves adjust the proportions of a mixture of cooled and room air which is delivered to the slots. Water condensed by the evaporator is collected in a drip tray, passed over the condenser to evaporate some of the water, and re-collected. Warm air is extracted from the room through slots around lamps 7 and a ceiling duct 8 by a fan 9 and used to form an air curtain over a doorway 11. A heat exchanger 10 extracts heat from the duct 8, to heat an air preheater 15. Air drawn into duct 8 is replaced by fresh air drawn through a filter 19, fine filter 20 and preheater 15 and passed into the room at one or more points 21a, or through slots in the walls near the floor. In another embodiment, cooled air is supplied through floor ducts to each unit 2 from a central air conditioning plant including a mixing chamber for fresh air and air drawn from the duct 8, a filter, preheater 15, a cooler, a humidifier, a reheater and a fan. An air delivery duct provided along the edge of the counter may include a grille to ensure even air distribution. Slots may be provided between adjacent compartments of a counter, all fed from a single duct. Alternatively, outlets may be provided in the sides of racks or counters, and may be covered with perforated sheet material or woven material.

Title: Temperature-compensated hall generator circuits
IPC: G06K5/02
Filed: 1972-03-09
Abstract: 1322139 Proximity detectors SIEMENS AG 9 March 1972 [10 March 1971] 10903/72 Heading G1N [Also in Division H3] To compensate for the effect of temperature variation on the output voltage of a Hall generator HG which is connected to a threshold circuit SCH through an operational amplifier OP, the quiescent output voltage of the amplifier is determined by the impedance of the Hall plate. As shown a control current IS passes between points 1 and 2 of the plate, and an output voltage is developed between points 3 and 4 when a magnetic field produced, e. g., by a permanent magnet attached to a printer type carrier traverses the plate. The Hall output voltage is applied through a capacitor C1 to the operational amplifier where it is combined with the quiescent output voltage to operate the threshold circuit. The amplification for Hall voltage pulses is determined by the rates of the values of resistors R3 and R1, while in the quiescent state the D. C. voltage between points E1 and E2 is amplified, this voltage consisting of the difference if the voltage drop via resistor R4 and the voltage between points 1 and 3 of the Hall generator. The value of resistor R4 can be chosen to give a zero output of the operational amplifier at a specific temperature, with the quiescent output voltage going above or below the zero value for higher or lower actual temperature, respectively.

Title: Improvements in Power Operated Electric Switches.
IPC: H01H3/58
Filed: 1917-07-31
Abstract: 114,098. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). July 31, 1917. Oil switches; electric motor actuation. -Heavy - current, oil - immersed, and like switches are operated and maintained in the closed position by an electric' motor which drives, the switch through a combined one-way and friction clutch, the friction clutch serving to hold up the motor when the switch reaches its closed position against spring and gravity action which restore the switch to the open position if the circuit of the motor is broken or reversed.' The motor 15 drives, through the clutch, a pinion 16 meshing with a gear sector 17 which lifts and lowers a rod 11 connected with the operating- member 10 of the switch which is located within the oil chamber 12. The pinion 16 is loose on the motor shaft 15<a>, Fig. 3, which has fixed upon it a notched member 25. An annular member 28 is loosely mounted on the shaft and surrounds the member 25, and rollers 27 located in the inclined notches permit one-way rotation only between the members 25 and 28. The member 28 carries also a fixed friction-ring 30 and a yieldable friction-ring 31 between which a friction-disk 32 on the pinion 16 rotates. To close the switch, the motor is energized and drives the gear sector 17 until the contacts are firmly closed, at which point an.extension 21 of the sector engages with a spring abutment 22 and holds up the motor which, however, still tends to drive through the friction clutch. If the current to the motor is cut off or reversed, the spring abutment and the weight of the parts cause the switch to open, thereby driving the pinion in the reverse direction and driving the motor backwards through the friction clutch until a second spring abutment 23 is engaged by the sector at the fully open position of the switch, and the movement of the switch mechanism stopped, the motor being allowed to continue its movement under kinetic energy by reason of the one-way clutch. This over-running movement insures against rebound of the mechanism when the fully-' off ' position is reached. The one-way clutch may be dispensed with.
