Title: Improvements in or relating to diaphragm pumps
IPC: F04B43/067
Filed: 1956-01-11
Abstract: 801,902. Diaphragm pumps. PLEUGER, F. W. [trading as PLEUGER & CO.]. Jan. 11, 1956 [Jan. 11, 1955], No. 1013/56. Class 102(1). [Also in Group XXVI] Pumping equipment comprises a pair of flexible diaphragms mounted in spaced relation between a pumping chamber and a driving means and having a pressure transfer chamber and a cylinder, filled with liquid, located between the diaphragms, the cylinder being in communication with the transfer chamber in which one diaphragm serves to seal the pumping chamber from the transfer chamber and the other diaphragm serves to seal the driving means from the cylinder. In the embodiment shown the pressure transfer chamber 15 and cylinder, formed as two concentric cylinders 16a and 16b, are sealed from the pumping chamber 12 and driving means 36, 37 by diaphragms 7 and 8a respectively. In operation the connecting rod 36 and drive shaft 37 reciprocate a two part crosshead 34, 34a which causes reciprocation of pistons 17a, 17b in cylinders 16a, 16b. As the piston 17a advances into the transfer chamber 15 the liquid in the chamber raises the diaphragm 7 and forces liquid out of the pumping chamber 12 past the usual non- return valve. As the piston 17a returns to the cylinder 16a the diaphragm 7 moves downwards and liquid is drawn into the pumping chamber. A recess 39 is provided at the bottom of cylinder 16a and liquid from the transfer chamber 15 which leaks past the piston rings 19a is returned to the transfer chamber 15 on the downward stroke of piston 17a through passageway 30a and non-return valve 31a. Liquid leaking past the piston rings 19b collects in recesses 29b and 29a and is forced past non- return valve 41 during the upward movement of the pistons by diaphragm 8a and joins the liquid collecting in recess 39. This leakage of liquid serves to lubricate the pistons 16a, 16b and crosshead member 34a. The lower crosshead member 34 may be lubricated either by grease provided in the bushing 35 or if the driving means in housing 11 operates under oil a lubrication recess 50 may be provided adjacent the lower face of the diaphragm 8a, and as the crosshead reciprocates the diaphragm 8a serves to pump the oil in the direction or the arrows 54, a non-return valve 51 being provided to prevent direct flow to the oil reservoir. A perforated plate 21 preferably provided with a resilient or elastic plastic coating 21a supports the diaphragm 7 when the pump is not in use or during the return stroke of the piston 17a. The diaphragm 7 and plate 21 may be set at an angle to the axis of the pump. In a modification the driving means may be a cam acting directly on the piston or on a ram in contact with the crosshead, the return stroke of the piston being effected by a compression spring in the transfer chamber. In a further modification the lower diaphragm is a complete circular member clamped at its outer end and lying between the ram and the lower piston, in this case the two concentric cylinders and pistons may be replaced by a single cylinder and piston, the piston being hollow.

Vehicle lamps, directing; anti-vibration devices. -Vehicle lamps are mounted in such a manner as to permit angular movement in all directions and to damp vibrations and oscillations liable to damage the lamp. For obtaining adjustment in a horizontal plane, a barrel b is carried in ballbearings e, e<1> on a rod a<1> fixed to the vehicle. The barrel is connected to the rod by a coiledspring c under tension disposed within the barrel, which spring serves as an antivibration device for the lamp and also tends to rotate the barrel relatively to the rod against a flexible control cable g passing round and attached to the base of the barrel and operated by a hand-lever on the dash. Fitting over and secured to the barrel b is a cap j which carries the lamp-supporting forks j<1>.

Abstract: 555,134. Measuring pressure. KLEMPERER, O. E. H. Feb. 3, 1942, No. 1406. [Class 37] [Also in Groups XIX and XL] A pressure gauge comprises an electric discharge device adapted to be immersed in the atmosphere of which the pressure is to be measured, said device including a cathode substantially surrounded an anode and means for causing electrons to travel in long paths between cathode and anode so that sufficient ionization takes place to produce a desired indicating current. The cathode C is a cylinder having end discs through central holes in which a rod A of tungsten wire passes, the wire having been dipped in thorium nitrate and warmed up gently to provide a thin radio-active coating of thorium oxide on the anode. The electrodes are set up in a bulb T communicating by a pipe V with the space in which is the gas to be measured. A solenoid M disposed coaxially with the cathode C provides the axial magnetic field. The cathode is earthed through a microammeter ÁA, while a voltmeter KV is provided for measuring the voltage between the anode and cathode. In a preferable indicating circuit, Fig. 5, the load resistance is in the cathode lead and comprises a high resistance N and a lower resistance R, the voltage across the latter being amplified in a variable valve V1. In a modification, the valve is connected to operate as a cathode follower valve and a voltameter across the device AC is adjusted until the milliammeter gives the particular indication corresponding to a particular current through the device AC. In a final form, the instrument MA is dispensed with and a visual indicator used of the kind described in Specification 481,790 and known as the " Magic Eye " the pattern on which closes at a particular value of the current through the gauge and the vacuum is determined by the voltage across AC when the pattern just closes. The voltage is derived from a potentiometer in connection with a main supply. Specifications 474,845, 481,790, [Group XL], and 493,274 are referred to.
