Title: Measuring valves
IPC: G01F15/00
Filed: 1932-12-16
Abstract: 400,444. Fluid-actuated valves. CHACE, P. G. and KIENLE, J. A., 1600, Beard Avenue, Detroit, Michigan, U.S.A. Dec. 16, 1932, No. 35687. [Class 135.] A liquid meter having a rotor 69 on a vertical shaft 72, and provided with means to deliver a predetermined quantity of fluid before a valve, or valves, is, or are, shut by a tripping mechanism, is given a non-turbulent supply of liquid by means of walls 66 provided with inner and outer baffles 80, 81, compelling the liquid entering chamber 11 to descend upon the rotor in a vertical direction. The rotor has buckets 83 in a disc 69 which has a boss 74 secured by cross pins 77 to the shaft 72, and revolves on a bush 71. One of two inlet valves is shown in Fig. 3 and is actuated manually through a handle 37 provided with a tooth 39 on the handle spindle 38, which raises the valve body 18 to permit liquid to flow from an inlet 8 to an outlet 9 leading to the rotor chamber 11. To ease the valve on opening a cap 32 is raised slightly off a seating on a rubber disc 36 to permit liquid to pass through a passage 30 to a chamber 23 and thus give an upward pressure on the underside of the valve 18. This takes place before the upper portion 19 of the valve is raised to admit the main liquid supply. The dial 48, Fig. 1, is calibrated in gallons and is shaped to a point 49 at the zero reading to trip a bar 43 which is pivoted to the meter casing, when the desired quantity of liquid has passed through the meter. The end of this bar 43 is provided with an adjustable latch which co-operates with ratchet teeth 46 on a cam forming part of the operating handle 37. When the bar is tripped, the weight of the handle causes the valve to close. The dial 48 is connected to the meter shaft 72 by means of a friction clutch 57 allowing the disc to be turned to a set figure, and gear wheel 59 on a shaft 50, gears 54, 85, on a spindle 53 and further gears 88, 90 the latter meshing with a worm drive 91. Thetwo inlet pipes 4, 4a, may supply hot and cold liquids. The dial 48 is secured to its shaft by a U-shaped washer 56 in a groove 55. Packing rings 67, 68, the latter non-corrodible, are provided. A gland 73a prevents leakage of lubricating oil from a chamber 86, along the shaft 72. A detachable plate 87 prevents the ingress of dirt, and also permits easy inspection of internal parts. A thrust bearing 92 supports the rotor shaft. A felt washer 94 is saturated with lubricating oil.

Title: Frequency responsive speed control apparatus
IPC: B60T8/58
Filed: 1974-08-14
Abstract: 1483795 Measuring vehicle speed electrically GENERAL SIGNAL CORP 14 Aug 1974 [10 Sept 1973] 35845/74 Heading GIN(A) [Also in Division H3]  In vehicle speed monitoring apparatus comprising means 12 for generating a signal with a frequency dependent on speed an underspeed relay 6 is maintained energized only while the speed signal has a frequency less than a threshold value set by speed select 11-1 and this threshold value is less than the frequency of a check signal supplied by oscillator 10 which is slightly higher than a frequency corresponding to a predetermined speed of the vehicle, the relay driver 17 responding to the alternating application of the said speed and check signals to the filter 14 to hold the relay 6 energized. In the embodiment of Fig. 2 the speed or check signals amplified by amplifier 13 are fed to a monostable multi-vibrator, comprised by transistor Q2, - Q3, which delivers a positive pulse of predetermined duration to cause transistor Q4 to conduct for every zero crossing of the input signal. If the frequency is above the threshold value the rate of conduction of Q4 is such that capacitor 40 charges to a voltage at which complementary uni-junction transistor Q5 conducts. The resulting pulse is applied via squaring network 15 to integrator 16 where it inhibits conduction of transistor Q10. The condition of Q10 controls the operation of transistors Q11 and Q12 which in turn control the charging and discharging of a pair of capacitors 80 and 83, the alternate discharging of which maintain the relay 6 energized. When transistor Q10 conducts transistor Q 11 conducts and transistor Q12 cuts-off and supplies sufficient bias to cause transistor Q9 to conduct so closing switch 9 and connecting the output of the check oscillator, at a frequency selected by resistors 71-75, to the amplifier 13. This inhibits response of the amplifier 13 to the speed signal and if the check signal frequency is higher than the threshold value conduction of transistor Q10 is again inhibited. Thus under normal conditions repeated operation of transistors Q11 and Q12 is achieved and the relay 6 maintained energized. Pulses from amplifier 13 are also fed to a motion detector 7 which maintains a relay 8 energized while the vehicle is in motion thus providing a check on the axle generator 12.

Abstract: 987,710. Shearing. F. MOELLER, and K. NEUMANN, [trading as MOELLER & NEUMANN o.H.G.]. Sept. 24, 1962, No. 36217/62. Heading B3W. An edge trimming shear for plates has two moving cutters, means for imparting a relieving movement to at least one cutter, and further guiding and reciprocating drive means for moving said cutters in the direction of and in unison with, the plate feed during the cutting operation so as to perform a flying trimming cut, and for moving said cutters back to the starting position after the relieving movement of the cutters. A trimming shear comprises a lower part 2 in which is formed an arcuate guide track 2a in which runs a cutter support 4. A longitudinal cutter blade 6 with a curved cutting edge, and a cross-cutter 8 is mounted in the support 4. The underside of the support 4 has gear teeth which are engaged by a pinion 16 which is rotated by engagement with rack-teeth formed in bar 25a attached to the piston 25 of a double acting cylinder 24. The centre of curvature of the blade 6 coincides with the centre of curvature of the guide track 2a. An upper part 1 of the shear comprises a similar guide track 1a a cutter support 3, cutters 5 and 7 and a driving pinion 15. The upper part 1 is pivoted on a pin 17 and is rocked by a crank drive 18, 19. A plate 21 passes through the shear from right to left (Fig. 1) and is severed as it passes through the vertical plane 11 joining the centres of curvature 9 and 10. The cross-cutters 7 and 8 chop the trimmed-off strip into convenient lengths. The crank 18 is moved through 180 degrees to raise the upper cutter clear of the edge of the plate and the pinions 15 and 16 are reversed to return the cutters to their starting position. In a modification to permit continuous feeding of the plate 21 the cutters are arranged so that the shearing plane moves against the direction of movement of the plate 21 as the cutters operate. In this case (Fig. 4) the lower cutter 6a has a rectilinear movement and the upper cutter 5a has an arcuate movement but the centre of curvature 9a of the cutting edge of the blade 5a is at a greater vertical distance from the plate 21 than the centre of curvature 23 of the guide track 1b. The time taken for the cutters to return to the starting position is provided by the time taken for the end of the cut, i.e. that part made by the cross-cutters, to move to the point 11a in Fig. 4.

Title: Electromechanical filter assemblies
IPC: H03H9/05
Filed: 1975-09-04
Abstract: In the construction of circuit units which contain more than one electro-mechanical filter on a common base plate, the problem is that mechanical oscillation energy can pass from one filter, via the holding legs of the mechanical filter resonators and the base plate, to a second filter, and can affect the incoming or outgoing signals there. To avoid this, in the case of at least one filter, the base plate (1) consists of plastic, with trough-like depressions (8) for fixing the holding legs. Cast resin, which remains elastic after hardening, and has a greater mechanical damping factor than the base plate material, is poured into the depressions as a filler (9). Such electro-mechanical filters are particularly suitable for use in carrier frequency devices. <IMAGE>
