Title: Pyrometer
IPC: G01J5/28
Filed: 1967-09-14
Abstract: 1,197,090. Photo-electric temperature measurement. BECKMAN INSTRUMENTS Inc. Sept.14, 1967 [Sept.22, 1966], No.42017/67. Heading G1A. [Also in Division G3] A photo-electric pyrometer comprises a photoelectric detector on to which is directed radiation from an object under investigation, means measuring the detector output for indicating the temperature of the object and means sensing when the temperature of the object drops below a certain level to initiate heating of the object. Radiation from the hot object 10 enters the pyrometer through a lens 11 Fig.1, and reaches a beam splitter 12 which directs 10% of the radiation towards an eye-piece 15 and the other 90% through an aperture 16 a chopper 21 (which provides an A.C. detector output) and a filter 18 which passes infrared in the band 1À7 to 2À6 microns. The detector 19 located after the filter is a lead sulphide photo-resistor accurate in the range 200- 1500‹ F. with the described optical system. The detector is enclosed in a casing with a heater circuit comprising a thermistor (THI) Fig. 5 (not shown) and two transistors (91, 92) one being heat emissive to maintain it at a predetermined temperature and keep its sensitivity unaffected by outside influences. The detector output passes through a transistor pre-amplifier 52 Fig. 4, a range selector 53 provided with meter range selection, "calibrate" and "off" positions, the main amplifier 54 having five transistors and various gain controls, to the primary of a transformer, the secondary circuit of which includes a full wave rectifier, and a meter 55, indicating the temperature of the object. A recorder may also be operated. The detector signal is also used to control the connection of power to a heating element to heat the object under investigation if its temperature drops below a pre-set level. An A.C. or D.C. voltage is obtained from a resistor in the meter circuit and applied to a variable resistor (R60), Fig. 5 (not shown) by which the response level of the circuit is set. If the temperature and thus the detector output voltage goes below a certain level a transistor circuit (Q26 and Q25) causes a unijunction transistor (Q24) and thereby S.C.R. to fire, connecting the power supply to the heating element via a bridge rectifier circuit. The circuitry detailed in Fig. 5 (not shown) also includes the automatic voltage controlled supply circuits for the heater (for the detector) and amplifier circuits (Q17-19, and, Q20-Q22) and for a reference tungsten lamp (L) used, in association with a light guide, (Q12-16) in calibration of the pyrometer. Also included is the supply circuit for a solenoid (32) which controls the introduction of a shutter 20 into the radiation path to block off external radiation during calibration using the reference lamp (L).

Abstract: 1314606 Spreaders for lifting articles F G ULLRICH and Z E ULLRICH 3 Sept 1970 [16 June 1970] 42275/70 Heading B8H A spreader for use with a lifting device comprises a frame 10 on which lifting arms 29 are pivotally mounted on axles 27 and each connected at one end to lifting means (48), Fig. 1 (not shown), the arms 29 on one of the two longer sides of frame 10 (called the drive side) having an actuating lever 44, Fig. 5, which engages a ratchet 43 on a triangular shaped block 42, the blocks 42 being connected to similar blocks 42 on the opposing side of the frame by cross tubes 36. On operation of the lifting means (48) the application of load causes the arms 29 on the drive side to turn inwardly about their axles 27 thus causing levers 44 to pull on the ratchet 43 and turn it through onesixth partial rotation, the rotation being simultaneously transferred to the arms 29 on the other side of the frame through cross-shafts 28, 36, and the base of each block 42 bears against the respective arm 29 in locking engagement as shown in Fig. 5. In disengaging the load, the ratchets 43 and their respective blocks 42 rotate forward under gravity and spring means thus allowing the associated arms 29 to move outwardly away from the frame 10.

Abstract: 901,948. Hydraulic presses. HERION, E. Dec. 14, 1960 [Dec. 21, 1959], No. 42964/60. Class 69 (2). A safety control mechanism for controlling the operation of at least one fluid-pressure actuated apparatus, such as a press, comprises at least two individual valves 1, 11 which are connected in parallel and actuated simultaneously either mechanically or by solenoids 15, each valve being connected to only one fluid-pressure actuated apparatus by outlets 3 and having a movable valve member 4 adapted to engage a valve seat 5 to close a valve port connected to a pressure inlet 2, and each valve seat having a channel 6 connected to a pressurecomparison means 9 whereby in the event of faulty operation of one of the valve members, the pressure-comparison means automatically interrupts the pressure supply to the fluidpressure actuated apparatus. The channel 6 in each valve seat is connected by a by-pass 7 to the pressure inlet 2 and by a conduit 8 to the pressure-comparison means consisting of a piston 9 spring-urged to a central position in a cylinder. Faulty operation of one or other of the valve members results in a pressure differential at the valve seats moving the piston 9 to actuate a member 11 interrupting the supply to the fluidpressure actuated apparatus by operating a switch 16 in the circuits to the solenoids or by shutting off the pressure supply to the inlets 2. An adjustable throttle 13 may be disposed between the ends of the piston 9 to permit slight fluctuations of pressure to occur in the channels without operation of the member 11. The valves may be combined in a double valve or each valve may be of the three-way type having further valve seats 5<SP>1</SP> provided with channels 6<SP>1</SP> connected by by-pass passages 7<SP>1</SP> to the pressure inlets 2 and by conduits 8<SP>1</SP> and one-way valves to the ends of the same or a separate piston 9. Each valve member 4 has a projection 13 which acts to close the port between the inlet and outlet before the valve member engages the valve seat.
