Title: Improvements relating to pressure fluid intensifier devices
Inventor: CHARLTON ROY
IPC: F15B3/00
Filed: 1961-07-05
Abstract: 938,771. Hydraulic intensifiers. HORDERN. MASON & EDWARDS Ltd. July 5, 1962 [July 5, 1961], No. 24207/61. Class 69 (2). A pressure intensifier comprises an input chamber 16 for connection to a primary source of fluid, such as air, under pressure, an output chamber 24 for containing a secondary fluid, such as liquid, in which pressure at a higher value than that of the primary fluid is to be established, and a movable thrust-transmitting member 21 intervening between the chambers and having a rigid component 22 forming part of the boundary wall of the output chamber, the component being sealed with respect to the adjoining parts of the boundary wall 29 of the chamber by an elastically-deformable sealing member 27 extending peripherally of the rigid component and joined or connected to this component and to the adjoining part of the boundary wall of the output chamber in a fluidtight manner. The wall 29 is integral with a dome-shaped casing 10 between which and a support 12 is clamped the peripheries of a plate 14 and flexible diaphragm 15. The plate 14 serves as a backing plate to the diaphragm and is formed with a recess 16 constituting part of the input chamber which is connectible by a pipe 17 to a source of air under pressure. Disposed on the opposite side of the diaphragm 15 is a disc 19 welded to a flange 20 of a thrust-rod 21, the end of which is received within the cupshaped component 22; the disc, rod and component constitute the thrust transmitting member. The sealing member 27, which may be of rubber or similar material is bonded to the component 22 and to a liner 28 or the wall 29 and permits movement of the thrust-transmitting member as a result of air pressure in the chamber 16 to intensify the pressure of the liquid in the chamber 24. The dimensions of the sealing member 27 are such that the stresses set up in the sealing member during movement of the thrust-transmitting member are predominantly shear stresses. An annular member 25 of rubber or similar material is received tightly within the bore of the wall 29 and on a portion of the rod 21 bounded by a flange 26 and serves to guide the rod 21. An indicator 50 may be moved manually against a spring 46 until it abuts the disc 19 to determine the position of the thrusttransmitting member. When the disc 19 has moved to its extreme right-hand position, it engages and moves a rod to open a valve and connect a source of pneumatic pressure to a pressure-responsive switch which may control apparatus, such as an hydraulic press, and indicates that the limit of the stroke of the intensifier has been reached. In an alternative embodiment, the diaphragm is replaced by a resilient member joined or connected to the side wall of the input chamber and to the periphery of a rigid control component in a similar manner to the member 27.

Abstract: 1348718 Fluid pressure-relieving devices BUEHLER A G Gebr 19 April 1971 [20 March 1970 7 Sept 1970] 24536/71 Heading F1D A pressure-relieving device, Fig. 2, comprises a cover 20' having a peripheral resilient ring 11 which is grooved to receive the inner periphery of an orifice in a housing containing a pressurized chamber. The side of cover 20' remote from the chamber is connected by straps 21, 25, pivoted at 22, to the housing 1'. If excess pressure builds up in the chamber the force on cover 20' forces the resilient ring 11 out of engagement with the orifice. In a further embodiment, Fig. 5, a cover 103 is hingedly connected at 106 to the housing, and when the orifice 102 is closed by the cover 103 and spring loaded detent 113 attached to cover 103 engages a recessed bracket 131 on the housing. A further rod 150 is pivoted at 142 to the housing and slidably projects through a sleeve 146 attached to cover 103. When the cover 103 is blown open the sleeve 146 abuts against spring means 155, 157 which thus reduce the speed of the cover 103 to zero. Further embodiments similar to that of Fig. 2 are shown in Figs. 1. 3 and 4, (not shown), and Figs. 6 and 7, (not shown) illustrate embodiments employing the principles of Fig. 5.

Abstract: 1,066,476. Read-only memories. HITACHI SEISAKUSHO KABUSHIKI KAISHA. June 12, 1964 [June 12, 1963], No. 24569/64. Heading G4A. A semi-permanent memory device consists of a word drive line 1 and a digit line 3 on either side of an electroconductive film 2 and separated from it by insulating films 5, 6. If a high-frequency current is applied to the drive line 1 a high-frequency magnetic field is set up, the strength of which diminishes rapidly within the film (Fig 2(a), not shown), and a small voltage is induced in the digit line 3. If a permanent magnet 4 is now placed above the digit line 3 the lines of force will be affected (Fig 2(b), not shown) and a larger voltage will be induced in the digit line 3. The drive lines and digit lines may be formed in a two-dimensional array on substrates by etching or by vapour deposition. The permanent magnets may be in the form of films on a non-magnetic film and may be formed by coating or vapour deposition, appropriate magnets being removed by a perforator (Fig. 5(ii), not shown). Alternatively all the magnets may be demagnetized and then only the required ones remagnetized. Then, to change the stored information, it is only necessary to remove one film and replace it by another appropriately magnetized.

Abstract: 1317845 Measuring pressure electrically; measuring resistance BAILEY METER CO 19 April 1971 [26 March 1970] 24603/71 Headings G1N and G1U A pressure transducer comprises an n-type silicon diaphragm 10 into which are diffused a Piezo-resistor Rp of a p-type semi-conductor material and a resistor R T  also of p-type material but disposed in such a way on the diaphragm as to be insensitive to pressure, the resistors are in a two-element "bridge" 12 feeding an output voltage via temperature compensation circuit 26 and acting with differential amplifier 18 to control a D.C. amplifier 20, voltage to current converter 22 and feedback circuit 24 whereby current is fed back to the differential amplifier or to the D. C. amplifier which causes a reduction of the "bridge" output voltage while a current proportional to that fed back is supplied over a conductor 14 or 14<SP>1</SP> to a load resistor 34 and indicator recorder 36 to measure the pressure applied to the diaphragm. The conductors 14, 14<SP>1</SP> are also used to supply power to the transducer circuits at a station A remote from the indicator and energization station B. In the embodiment of Fig. 2 the increase in voltage e o due to pressure change causes increased current in conductors 14, 14<SP>1</SP> and increased bias voltage across resistor 100 whereby feedback transistor 98 increases its conduction accordingly to regulate the current flow through R T , by means of connection 25 to transistor 64, to bring the voltage difference across terminals 12b, 12c substantially to zero whilst maintaining the current in conductors 14, 14<SP>1</SP> at the increased value proportional to the applied pressure. To compensate for unequal positive temperature coefficients of resistance of resistors R p , R T  a Zener diode 70 is connected to the base of transistor 62 and, for the same purpose, a thermistor 184 is connected across resistor 100. In an alternative embodiment, Fig.3, feedback current is applied to the emitter of transistor 138 of the differential amplifier to re-balance the voltages between the collector terminals of transistors 138, 140 whilst sustaining the output current signal in conductors 14, 14<SP>1</SP>. Temperature compensation is provided by a third and pressure insensitive resistor R tc  diffused into the diaphragm and having a positive temperature coefficient of resistance K tc  which is arranged to be equal in magnitude to that, K r , of the Piezo resistor, which latter is negative, to achieve stability. In addition an external resistor R x  is connected in series with whichever of R P  and R T  has the larger temperature coefficent, R x  being substantially temperature insensitive and of magnitude according to the expression or where K p , K T  are temperature coefficients of R p , R T . A diode-connected transistor 186 provides "tracking" of the base-emitter voltage of transistor 130 to provide additional temperature compensation.
