Patent GB-107058-A (GB)
IPC: F16H43/02
Abstract: 107,058. Constantinesco, G., and Hadden, W. June 14, 1916. Percussive drills.-In a hydraulic transmission system of the kind described in Specifications 9029/13 and 12438/14, [both in Class 69 (ii), Hydraulic presses &c.], means are provided for cutting-off the supply of energy from an apparatus situated on a branch pipe from the main transmission pipe by the regulation of a leak on the branch line. In the apparatus shown in Fig. 1, the main transmission pipe is connected at a and the branch pipe at b. An oscillating piston c with a central opening is controlled by a spring d. A fixed spindle c has its upper part reduced in diameter at f. If the mean pressure in the branch line is caused to drop, the piston c is forced on to the spindle e and cuts off the branch pipe. The piston may be replaced by a flexible diaphragm, and in both cases a small leak is normally allowed past the spindle c. In a modification, Fig. 3, the main pipe is connected at a and the branch pipe at b, a differential piston k, l being interposed between the two. The piston slides over a rod m with a small clearance. If the leakage from the branch pipe is stopped by a valve, or if it is made excessive the mean pressure increases or decreases on the branch line side, and the piston is pressed to one end or other of its stroke, and its oscillations thus stopped. In a modification, the middle part of the rod m is of smaller diameter, and the apparatus may be used with tools such as rock drills in which considerable leakage is normally allowed. If the leak in the branch pipe is increased, the piston is forced upwards on to the increased diameter of the rod which cuts off the supply. If the leak from the branch pipe is stopped, the piston is forced downwards on to the increased diameter of the rod. Specifications 4349/15, [Class 69 (ii), Hydraulic presses &c.], and 4350/15 are referred to.

Abstract: 1504455 Cams; valves BRADLEY CORP 17 March 1976 [4 Aug 1975] 10821/76 Headings F2K and F2V A manually axially movable and rotatable generally cylindrical rod or spindle-like control cam 18, for a tubular diaphragm sleeve type fluid mixing and proportioning valve, has an end tapered surface region 21 which extends from a generally cylindrical portion 20 and is canted from the axis 24 thereof and formed as two inclined steps to form initial and end tapered surfaces 28, 26 respectively, the end tapered surface 26 tapering towards the cam axis 24 at a greater angle than the initial tapered surface 28. The two inclined steps 28, 26 are formed as part-conical surfaces and extend partially around the circumference at the tapered end region 21, the remaining part of this circumference being cylindrically formed at 25 and extending along an axis 23 canted at an angle # to the main cam axis 24, the transition zone between the inclined cylindrical zone 25 and the part-conical zones 28, 26 being of a concave form 27. The rod or spindle-like control cam 18 is used in a mixing valve having hot and cold water inlets 5 which communicate via passages 6, 7 and ports 9, 10 with a mixing chamber 8 within which is located an open ended plastics double sleeve 12, 15, the cam 18 engaging within the outer and inner sleeves 12, 15 the latter merely serving as a stiffening support for the outer sleeve 12 and being suitably cut-away to allow free operation by the cam 18 of valve sealing cushion portions 13, 14 on the outer sleeve 12. With the spindle-like cam 18 fully depressed (Fig. 1) the cylindrical portion 20 thereof prevents movement of the sleeve sealing portions 13, 14 away from the inlet ports 9, 10 and thus prevents flow. Raising of the spindle-cam 18 controls the volume (i.e. quantity) flow rate whilst rotation thereof varies the ratio (i.e. proportions) of the hot and cold water flow through the inlet ports 9, 10. The outlet 3 from the mixing chamber 8 leads to an annular recess defined by the valve body 2 and a rotatable sleeve which is formed with a discharge spout 11. Reference has been directed by the Comptroller to Specifications 1,273,063 and 4,117,547.

Filed: 1968-03-07
Abstract: 1,204,961. Medical dispenser/container. PRODUCTS RESEARCH & CHEMICAL CORP. 7 March, 1968 [7 March, 1967], No. 11231/68. Heading A5R. A container for two fluids in which the fluids can be mixed and ejected comprises a cartridge 12, e.g. of plastics material, having a nozzle 38 provided with a slide valve (see Fig. 8, not shown) at the forward end and an ejecting piston 34 at the rear. The operating knob 36 is attached to the end of a central tubular member 35 which contains one of the fluids and which is closed at the forward end by a sliding valve (see Figs. 5 and 6, not shown) which is opened by the hydrostatic pressure generated when the ram rod 62 is forced down inside the tubular member to force the fluid therein into the main container. This having been done, the rod is withdrawn and oscillated in the main container to allow the dasher 66 (see also Fig. 4, not shown) to mix the fluids. When mixing is complete, the rod is fully withdrawn and the snap ring 72 is forced into the groove 70 to lock the piston on to the forward end of the rod and pressure on the knob 36 ejects the mixed fluids when the locking clip 92 is removed. The device is designed for use with a suitable catheter to inject a rapidly setting resin into body cavities to prepare moulds of their internal configuration as is disclosed in Specification 1,204,962.

Title: Improvements in or relating to apparatus for geophysical exploration
IPC: G01V5/06
Filed: 1944-06-12
Abstract: 590,601. Observing radio active effects. CLEVELAND, F. J. (Wells Surveys, Inc.). June 12, 1944, No. 11241. [Class 97 (iii)] [Also in Groups XXXV, XXXVI and XXXVIII] In apparatus for geophysical exploration within a 'well - bore, wherein an ionisation chamber controls the magnitude of a minute direct current in response to the intensity of radiation impinging upon it, a voltage drop derived from this current is converted into a pulsating voltage, by continuously varying a capacity connected across the voltage drop, and then passed through an alternating current amplifier, the output from which actuates a meter to record the ionisation current. A null method of measuring the ionisation current may be used, in which case the amplifier output automatically varies the potential drop across a further resistor to balance that derived from the ionisation current. The ionisation chamber, which consists of a hermetically sealed compartment 5 containing spaced iron or other electrodes 6, 7 in an atmosphere' of inert gas such as nitrogen under a pressure of the order of twenty atmospheres, is mounted together with the amplifier in a casing 3 adapted to be lowered into a bore-hole by a cable 4. The electrodes are connected in series with a battery 8 and a high resistance 9. The potential drop across resistor 9 which is a measure of the ionisation current is applied through series connected high resistance 12 and condenser 13 to the input terminals of an A.C. amplifier 10. Connected across resistors 9, 12 is a condenser, one plate C1 of which is oscillated towards and away from the corresponding fixed plate C by an electromagnet 20 energized from an A.C. source 19, so that the voltage across the resistor 9 is applied to the amplifier 10 as a series of pulses. The amplifier output is fed by the cable 4, slip-rings 21 and brushes 22 to a further A.C. amplifier 23, the output from which actuates a recording A.C. voltmeter 24, the record paper of which is driven through a shaft 26 from a spool 27 contacting the cable 4 to correlate the recording with the depth of the measuring device. Alternatively, the recorder may be synchronized with the cable 4 by selsyn control. In a modification, an additional resistor, Fig. 2 (not shown), is interposed in the line 11 between the +ve battery connection to resistor 9 and the wire 18 connected to the condenser plate C1 and fed with a voltage to balance out the voltage drop across the resistor 9. This balancing voltage is derived from a recording potentiometer located at the surface and automatically adjusted by the A.C. amplifier output and' is a measure of the ionisation current. The condenser CC1 operates in air or other gas under pressure.
