Inventor: SKAPPEL E
IPC: A01G25/16
Filed: 1980-02-18
Abstract: A main valve (1) is connected into a pressurized water pipe for an irrigation installation and has a valve body (4) formed as a differential piston and with a through bore (5), said body being operated in both directions by means of the water pressure, the piston (4) in one end position closing the water pipe and in its other end position keeping it open. The piston (4) is guided to said end positions by means of a control valve (7) arranged to open or close a duct (6) starting from the major cylinder bore, thereby to cause the water present to actuate the piston (4). The control valve (7) is in turn controlled by rainfall onto, and evaporation from an upwardly open bowl (8), and a drop means (9) active during irrigation. The bowl (8) is part of a tipping means with two tipped end positions, controlled by the quantity of water in the bowl (8). To achieve operation of the main valve (1) such that irrigation substantially takes place at night, and that the length of time between irrigation can be varied, the tipping means is supplemented by a closed air chamber (15) on the other side of the pivoting shaft (35), said chamber and bowl (8) having a common flat bottom (16) and mutual communication via a slit (17) at the bottom. By the volume change in the air enclosed in the air chamber (15), caused by the temperature difference between night and day, the quantity of water contained in the open bowl (8) and in the chamber (15) is displaced at night such that the tipping means tips over into a position opening the main valve (1).

Title: Improvements in or relating to electric stapling machine
IPC: B27F7/19
Filed: 1957-01-04
Abstract: 823,561. Stapling machines. SWING- LINE Inc. Jan. 4, 1957 [March 12, 1956], No. 450/57. Class 89(3) In an electric stapling machine having an arm SA, Fig. 3, 'comprising an open topped magazine M and a pivotally openable cap CP carrying a staple ejecting blade DB, Fig. 9, a vertically guided armature 32 of an electric solenoid SD is pivotally connected to the rear end of a lever MT which is disposed below the arm SA and solenoid SD, the lever MT being pivoted intermediate its ends and connected at its front end to a driving means 29 carried by the cap CP. The circuit of the solenoid SD is closed by a switch MC, Fig. 17, within the casing C, having an operating member CP<SP>1</SP> which is engaged by a spring loaded trigger T pivotally carried by the lever MT, the arrangement being such that by manually slightly depressing the cap CP to rock the rear end of the lever MT upwardly, the switch operating member CP<SP>1</SP> is moved to the position shown in Fig. 17A in which the switch contacts 98, 102 are closed. The solenoid is thereby energized to attract the armature 32 upwardly which rocks the lever MT downwardly at its front end causing the cap CP to be fully depressed to drive a staple. Near the end of the staple driving operation the trigger T releases the switch operating member CP<SP>1</SP>, Fig. 17C, causing the switch contacts to open. On completion of the staple driving operation, the arm SA returns to its original position and the trigger T is reset into the position shown in Fig. 17. The sensitivity of the switch to the initial manually actuated movement of the cap CP is controlled by means of a screw 115 which can be rotated to adjustably depress a resiliently supported insulated plate 40 on which the switch is mounted, thereby to determine the spacing between the switch MC and the trigger T. To permit the cap to swing about its pivot 18 away from the magazine M, the lever MT can be retracted to disconnect the lever from the driving means 29, by swinging the solenoid SD about a pivot 37 by means of an actuator 130, the pivot 57 of the lever MT being engaged by a slot 58 in the lever MT. The pivots 18, 37 are seated movement. Means 150, 151, Fig. 9, are provided to retain the cap CP in its open position. When the cap CP is again swung towards the magazine, the drawing means 29 automatically re-engages with the lever MT. The pivots 18, 37 are seated in bearings formed in the casing C and are secured by a keeper which also serves to secure the switch MC. A magazine cover CS carries a roller for the staple feed spring HS mounted in opposed slots 21 in the side walls of the cover CS, the ends 20 of the roller being releasably engageable in notches 23 to locate the cover CS in relation to the magazine.

Title: Barometric pressure transducer
Inventor: APPLETON NORMAN JOSEPH
IPC: G01L9/00
Filed: 1962-01-05
Abstract: 929,855. Measuring electrically. GENERAL PRECISION Inc. Jan. 5, 1962, No. 562/62. Class 40 (1). An atmospheric pressure transducer for use as shown, Fig. 2, in an altimeter, comprises a pair of identical vibrating elements, e.g. beryllium copper strings 13, 14 stretched between portions 12a, 12b of a preferably evacuated housing and opposite arms 17a, 17b of a lever 17 of the first class, the virtual fulcrum 18 of the lever being constituted by a tension spring 18a at the midpoint of the lever which loads the elements equally, and pistons 19, 20 which load the lever on opposed sides thereof in accordance with the pressure to be measured to form a pivotal couple about the virtual fulcrum. The strings 13, 14 vibrate in the fields of magnets 16, 16a at a frequency determined by the tensions of the strings, which are equal in the absence of pressure loading; the latter varies the tensions in the two strings differentially. The signals from the strings are fed to amplifiers 24, 25 (from which feedback circuits 26 are connected to the strings to maintain the vibrations) and are frequency multiplied at 27, 28, and combined in a mixer 29 whose output is filtered at 30 so that only a signal of the difference of the frequencies is passed to a comparison circuit 32 wherein it is compared with one of a number of reference frequencie 31a, selected by logical switching circuitry in a selector stage 31, the rough (lower) altitude thereby obtained being displayed on a dial 31b. The difference between the reference frequency and the test frequency is converted into a D.C. voltage in a discriminator 34 and fed to two torque coils 37 to offset the pressure loading to the extent that the transducer frequency equals the reference frequency; the output from the force balance system is taken from across an appropriate scaling resistor 38. In a modification, Fig. 3, one pair of pistons 19, 20 are permanently located relatively near the fulcrum 18 for use at low altitudes; and a second pair of pistons 39, 40 are located further from the fulcrum, for use at high altitudes; pistons 39, 40 may be unloaded from the lever by means 41. The vibrating elements may alternatively comprise devices as shown in Fig. 4, in which the frequency of vibration of a shaft 43, is varied by the change in tension of two strings 45a, 45b diametrically connected to a disc 44; Fig. 4a (not shown) depicts a modification of this device. The whole measurement of the frequency difference may be done in an analogue manneremploying acomplete force balance system; alternatively the whole measurement may be digital. The differential method of measurement provides compensation for variations of irrelevant variables, e.g. temperature, acceleration. A mathematical analysis of the invention, and the design characteristics of a preferred altimeter according to the invention, are contained in the Specification. Reference has been directed by the Comptroller to Specification 823,847.
