Title: Improvements in and relating to apparatus for washing coal, ore or the like
IPC: B03B5/24
Filed: 1957-05-06
Abstract: 842,401. Washing granulated materials. COPPEE CO. (GREAT BRITAIN) Ltd., and SANSAM, W. May 2, 1958 [May 6, 1957], No. 14401/57. Class 82(2) In a pulsating type jig for washing coal or ore, the depth of the shale bed X-X formed on a perforated grid 2 in the wash box 1, is regulated by an extractor rotor 5 driven by electric motor 6, the operation of which is automatically controlled according to the pressure at the underside of the grid 2, the pressure variation being transmitted via conduit 8 and pipe 9 to a pressure responsive mechanism which rotates pointer 10 over dial 11 to either open or close an electric circuit to the motor via contacts A or B. -When the depth of shale has increased beyond a predetermined maximum, the resultant pressure increase in conduit 8 is sufficient to rotate the pointer 10 to engage contact A which then closes the electric circuit to motor 6 through a relay R (Fig. 2, not shown). Shale is thus extracted from grid 2 until the depth of bed is reduced to the required minimum value when the pressure will have been reduced sufficiently that contact B is engaged by pointer 10, the electric circuit is opened and the extractor rotor 5 is stopped. In place of automatic operation the extractor may also be manually controlled by incorporating another switch in the circuit. In another modification the shale extractor may be continuously operated through infinitely variable gearing at a speed automatically regulated according to the pressure at the underside of the bed, the depth of bed thus being kept constant.

Filed: 1975-04-09
Abstract: 1469209 Measuring liquid level electrically LIQUIDOMETER CORP 9 April 1975 [10 April 1974] 14637/75 Heading G1N A capacitive type liquid level indicator includes a plurality of discrete capacitors 40 formed by an upright electrically conductive probe 16 and an upright row of electrodes 18 arranged in a tank 10, the probe 16 being supplied with an A.C. from e.g. astable multi-vibrator 24 and the electrodes 18 each being connected via a rectifier 44 and filter circuit 46, 48 to a respective comparator 52. During the negative half cycles of the multi-vibrator's output each of the capacitors 40 charges through its respective diode and then during the next positive half cycle when the diodes 44 are reverse biased the capacitors 40 transfer their charge to the respective filter capacitor 48. Depending upon the resultant D.C. level on lines 50 applied to the non- inverting inputs 56 of the amplifiers 52 the latter will assume either a low or high digital output if the D.C. level is below or above respectively the reference voltage applied to the inverting inputs 54 of the amplifiers. The values of 46, 48 are chosen so that in the absence of a liquid between the plates of capacitors 40 the amplifiers 52 assume a low state. If the liquid reaches the lowermost capacitor 40 so that its capacitance increases the D.C. level increases on line 50 and the amplifier 52 output 58 assumes a high level and needle 74 of indicator 70 moves roughly one eighth of full scale if the resistors 66 are equal. As the level rises each of the capacitors 40 increase in capacitance in turn and  their associated amplifiers change state to move the needle 74 further towards full-scale deflection. Instead of being connected to a meter the outputs of the amplifiers 52 may each be connected to a respective LED which are activated in turn as the level rises. The capacitors 40 are enclosed in an earthed guard shield 20.
Patent GB-618445-A (GB)
Title: Improvements in processes for packaging surgical string material
IPC: A61B17/06
Filed: 1946-05-16
Abstract: A sterilized surgical suture package is prepared by immersing the suture material in a water-immiscible fluid within an open container, the fluid containing a lower-boiling liquid having a boiling point higher than that of water and being vapourizable below the sterilization temperature and a higher-boiling liquid having a boiling point higher than the sterilization temperature, heating it until a substantial portion of the lower-boiling liquid is vapourized, thereafter heating to sterilize the suture material immersed in the remaining liquid, removing the remaining liquid, adding a storing fluid to the container and sealing the container. The lower-boiling liquid may be toluene, xylene ethyl benzene or a water-immiscible ketone.  The higher-boiling liquid may be mesitylene, cymene, cumene, decane or a water immiscible ketone. A mixture already containing both the lower- and higher-boiling constituents, such as kerosene, may also be used.  With "non-boilable" suture, the storage fluid (e.g. alcohol with or without potassium mercuric iodide) contains a small proportion of water.  Water must be absent from the storage fluid for "boilable" sutures, cumene or xylene being a suitable fluid; and in this case the process is modified by effecting sterilization after the container is sealed.  The sterilizing operation for non-boilable sutures may be effected at a temperature of 320 DEG  F., in a basket having a hinged wire-mesh lid and containing a number of tubes within which coils of surgical suture material are disposed.  After sterilization, the fluid is drained off by inversion of the basket, the lid is opened, the storage fluid is added and the tubes are sealed.

Title: Improvements in and relating to circuit arrangements for supplying x-ray apparatus
IPC: H05G1/48
Filed: 1938-05-20
Abstract: 515,055. Control systems for X-ray tubes. GENERAL ELECTRIC CO., Ltd., and CALDWELL, J. T. May 20, 1938, No. 15096. [Class 38 (iv)] Relates to the control of the H.T. of an X-ray tube to keep it constant, notwithstanding necessary variations of current in the cathode, by interconnected resistance regulating controls. In order to avoid the use of a regulating switch capable of carrying the full current of the primary of the transformer supplying the tube, a smaller switch is employed in the secondary circuit of a transformer through which the tube is supplied. In Fig. 1, the primaries of transformers 8 and 5 which supply a hot cathode X- ray tube 7 with low tension and high tension respectively are fed from alternating current mains 2 through an auto-transformer 1. A variable resistance 9 in series in the primary circuit of transformer 8 serves to vary the filament current, while the high tension voltage on the tube may be adjusted by means of a selector switch 3. Adjustment of a variable resistance 12 is effected conjointly with the adjustment of variable resistance 9 and the resulting variation in the impedance of a compensating transformer 4, connected in the primary circuit of transformer 5, maintains the voltage applied to the tube constant with varying filament current at any one setting of selector switch 3. The variable tapping from the switch 3 is taken through one winding of a transformer 4 to supply the primary of the tube transformer 5. The secondary of transformer 4 is connected across the regulating resistance 12 controlled conjointly with the resistance 9. The transformer coupling enables a regulating switch of relatively low rating to be used.

Title: Improvements in fluid pressure pumps or motors
Inventor: FIRTH DONALD
IPC: F01B1/06

Abstract: 902,012. Reciprocating pumps. COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. May 4, 1960 [May 4, 1959; Nov. 25, 1959], Nos. 15117/59 and 39968/59. Class 102(1). [Also in Group XXIX] A fluid pressure pump or motor includes piston type inlet and outlet valves in which one or both valves includes a sleeve in which the valve piston slides and which has a port in its wall controlled by the valve piston and registering with a cylinder port and means for adjusting the position of the sleeve relative to the bore in which the sleeve is fitted to vary the timing for opening and closing the valve. As shown in Fig. 1, a hydraulic motor having a plurality of radial cylinders 7 reciprocably mounting pistons 5 whose rods 3 formed with slippers 2 engage an eccentric 1 is fitted with piston type inlet and outlet valves 13, 14 respectively. Each valve comprises a twolanded valve piston 25 and a loosely fitting push-rod 15 urged by a spring against a tappet 18 which engages a cam 16 secured to the eccentric. The valve 13 controls flow between an inlet passage 26 and a cylinder inlet port 11 and the valve 14 flow between a cylinder outlet port 12 and an exhaust passage 27. The outlet valve 14 is fitted with a sleeve 50 loaded by a spring, (not shown), and formed with a port 52 which can register with the outlet port 12. A cam 40 rotatable by a lever 41 adjusts the axial position of the sleeve relative to the cylinder block 8 so that in the case of the motor the outlet valve closes just prior to the motor piston reaching T.D.C. so that the residual oil left in the cylinder space 10 from the exhaust stroke is compressed to approximately the inlet pressure to reduce hammering and shock waves to produce smooth running of the motor. In the case of a pump, the opening of the inlet valve is delayed after T.D.C. to allow the residual oil trapped from the previous delivery stroke to expand until its pressure approximates to inlet pressure. In a modification, the sleeve 50 may be rotated, the bottom of the sleeve being formed externally with gear teeth engageable with teeth on a reciprocable control rack. In another embodiment, the sleeve port or ports 152, Fig. 3, is or are symmetrically disposed about an imaginary helical line 157 and the working edge 63 of the valve piston is also of helical form of the same pitch. The valve piston is prevented from rotating by the engagement of a pin 65 in a slot 64 and the sleeve is rotatably adjusted by means of the engagement between pinion teeth 54 and a cylindrical rack 55. A counterbore 66 in the valve piston houses a valve loading spring 35 and a bore 69 connected to the counterbore relieves excess pressure from above the valve piston.
