Title: Improvements in hydraulically actuated raising and lowering apparatus
IPC: A61G15/02
Filed: 1938-11-10
Abstract: 522,421. Tables; chairs; easels. MAINA, J. Nov. 10, 1938, No. 32725. [Class 52 (iii)] [Also in Groups XXIX and XXV] Drawing tables, easels, dentists' chairs, surgical operating-tables &c. are mounted so as to be capable of vertical adjustment by means of a hydraulic-apparatus comprising a ram 4 capable of sliding in a cylinder 3 containing oil &c. and connected by a valve 7 to surrounding reservoir 2 containing oil and formed with airtight connection between itself and the cylinder 3 so that air under pressure can be pumped into the upper end of cylinder 2. The valve 7 is normally closed under spring action but by means of a pedal 8, or other device operable at a distance, the valve 7 may be opened to allow the ram to be raised to the desired position by the passage of the oil from the reservoir 2 under the action of the compressed air. The valve 7 is finally cut off, and the load on the ram 4 is then supported by the fluid beneath it. As applied to a draughtsman's table 6 carried by arms 28 on a shaft 26, the shaft 26 is mounted in a casing 27 carried by the ram 4, and the shaft 26 is angularly adjustable relatively to the casing by means of a pivot adjustment comprising a fixed gear 29, Fig. 3, with which engages an axially movable gear 30 secured to the shaft 26. The gears 29, 30 are normally held in engagement by balls 35 which are moved radially of the shaft 26 by a cam 36 on a sliding rod 32 which is moved axially by lever mechanism when it is required to adjust the table. This releases the locking action of the balls 35 and permits the table to be moved to the right in order to throw the gears 29, 30 out of engagement and thus permit of angular adjustment of the table.

Abstract: 1,187,953. Rotary compressors. HYDROVANE COMPRESSOR CO. Ltd. July 20, 1967 [July 21, 1966], No.32756/66. Heading F1F. A fuel-control device to regulate the speed of an I. C. engine for driving a rotary positivedisplacement compressor of the outwardly-sliding vane type includes a bellows 10 made of e. g. plastics material, and fixed to an immovable body 11 containing an axially-movable rod 15, which is attached at end end thereof to a disc 12 engaging with the bellows and is furnished with an annular disc or washer 30 that constitutes a piston, the latter being loosely lodged in a cylinder 17 that is charged with either a liquid or a paste through a passage 32, whereby movement of the disc 12 in response to changes in the pressure of gas within an inlet in the compressor (not shown) produces corresponding movement of the rod 15 against the retarding action of the piston. The pressure aforesaid is communicated to the interior of the bellows through a pipe-union 20 in a bore 21, containing a non-return valve-member 23, and a passage 24, the latter being in communication with a flow-restricting orifice 25 constituting a vent. The disc 12 abuts a compression spring 27 that effects inflation of the bellows through the orifice 25 when the pressure in said inlet rises and causes the valve-member 23 to move into its closing position. The rod 15 is connected by a lever (not shown) to a further rod that is coupled to a fuel-control member in the engine. Inflation of the bellows results in an increase in the rate of flow of fuel to the engine; and, to regulate the maximum speed of the engine, an adjustable stoprod 37 for the disc 12 is lodged in a boss 36 upon a cover 35 for the bellows. Axial movement of the rod 37 can be effected by rotating a screw 38 having an eccentric portion engaging with a circumferentially-orientated limb of an L-shaped groove 39 in the rod. Coarse adjustment of the rod can be performed when the rod is rotated to bring the axially-orientated limb of the groove into alignment with the said portion of the screw. The rod 37 may be replaced by a screw (45, Fig. 2, not shown), which has a circlip (47) thereon to restrict outward displacement thereof. The walls of the bellows are reinforced by rings 26.

Title: Method and apparatus for measuring residual rainfall
IPC: G01W1/14
Filed: 1974-10-11
Abstract: 1486412 Measuring rainfall BESTEL-DEAN Ltd 11 Oct 1974 [12 July 1973] 33279/73 Heading G1N(A) Apparatus for measuring rainfall comprises a  capacitor and means for supplying a predetermined change to the capacitor each time the increment of fallen rain equals a predetermined amount, a resistor across it, adjustable so that the rate of charge leakage through it is a function of the rate of rain dispersal, and means responsive to the resulting capacitor voltage indicating residual rainfall. The method is also claimed. Preferably the rain gauge comprises two buckets on a common pivot. When one bucket has a certain weight of rain it tips the arrangement to empty, to substitute the other bucket and operate a switch of a cricuit which causes a constant current generator to supply a predetermined amount of change which is adjustable to the capacitor, which is connected to high input impedance FET in an amplifier feeding an ammeter reading mm of rain, and a threshold detector, which causes a thyratrom to fire when the value exceeds that of a reference voltage, adjustable by a variable resistor, changing an output line from logic 1 to 0, which closes a relay setting off an alarm, or maintains it closed. A logic circuit on a second input to said relay only allows it to be operated immediately following the tipping of a bucket, and only when the voltage applied to the threshold detector falls below cut off level will the relay contacts open and reset the alarm. The above circuit can be for high intensity rain, with a second similar circuit for low intensity steady rain with the resistor across its capacitor adjusted to a different value, and operating a second alarm. The low intensity relay is inhibited by a logic circuit when the high intensity alarm is sounding. A plurality of such circuits having capacitors receiving charge increments may be used. Detailed diagrams and description of the circuit are given.
