Abstract: 435,295. Hydraulic transmission of power. DEHN, F. B., 103, Kingsway, London. -(Electric Household Utilities Corporation ; West Cermak Road, Chicago, U.S.A.) Oct. 13, 1934, No. 29384. [Class 69 (ii)] [See also Group VIII] The upper roller D, Fig. 1, of a wringer is journalled in a yoke 8 pivoted to a lever 73 which is fulcrumed at 76 and of which the other arm is connected to a hollow piston rod 70. The piston 50 works in a cylinder 10 and is raised, by fluid pressure derived from a rotary pump C driven by a vertical shaft 11, whenever a byepass 58 between the upper and lower portions of the cylinder is closed. The valve in the byepass comprises a rod 62 having two enlargements 61, Fig. 4, and slidable in a cylinder 63 intersecting and communicating with the byepass and having a push knob 66 at each end whereby the valve can be operated from either side of the wringer. The hollow piston rod 70 is apertured at 81, Fig. 1, and an adjustable spring-pressed ball 83 normally closes an axial passage 80 in the piston, but yields at a pressure predetermined by the spring 85 to relieve the pressure between the rollers as when articles of undue thickness are passed through the wringer. The lower roller E is driven in either direction by a reversible fluid pressure motor F of which the rotor 20, Fig. 2, is secured to the lower roller shaft, the supply of fluid pressure being derived from the same pump G that operates the roller pressure piston 50. The valve control for the motor comprises a rod 35 having enlargements 31-34 thereon and slidably mounted in a cylinder 30. The rod is operable by means of push knobs 27 positioned one on each side of the wringer. As shown, the supply of fluid pressure from the pump outlet 40 is cut off from the motor and is recirculated to the pump intake 14 through the ports 41-44. On moving the rod to the right, the ports 41 and 44 are closed and the fluid pressure passes to the motor through the pipe 24 and is returned through the pipe 23 and port 45 ; on moving the rod to the left the fluid pressure is passed to the motor through the pipe 23. The fluid is constantly withdrawn from the space above the piston 50 through the pipe 53 and is constantly returned to the space below the piston through the pipe 55.

Title: A device for separating imperfect cigarettes from a procession of cigarettes
IPC: A24C5/345
Filed: 1964-07-20
Abstract: 1,103,741. Cigarette making machines. MOLINS ORGANISATION Ltd. and G. F. W. POWELL. 25 June, 1965 [20 July, 1964], No. 29482/64. Heading A2C. A device for separating imperfect cigarettes from a series of cigarettes delivered to a fluted suction drum comprises means operative in response to the detection of imperfect cigarettes to cut off suction to the flutes containing the imperfect cigarettes at a position different to that at which suction is normally cut off so that the imperfect cigarettes are delivered at a different position to that at which normal cigarettes are delivered. The fluted drum 10 is provided at one end with a stationary valve body 16 and a stationary valve plate 17. The flutes are provided with suction holes 12 which communicate with the valve assembly 16, 17 through passages 14 and holes 29. Suction is applied through a pipe 15 under the control of a piston 23 slidable in the valve body 16 and which is operated from a normal position to that shown in Fig. 1 in response to the detection of imperfect cigarettes by a rod 31. For satisfactory cigarettes suction is applied to the holes 12 from the pipe 15 through holes 29, port 17A in the valve plate 17, a depression 18 in the valve plate 17, port 22A in the valve body 26 and recessed part 33 of the piston 23. As the drum rotates suction continues through port 21 and depression 20 in the valve plate, 17, port 22B in the valve body 16 and recessed part 34 of the piston 23. Thereafter suction continues through port 17B in the valve plate 17 which is in direct communication with pipe 15 through an oblique port 22C in valve body 16. Further rotation of the drum puts the holes 12 in communication with the atmosphere through a hole in the valve body, which is open to the atmosphere, and hole 19 and shallow port 17C in plate 17. The cigarettes are thus discharged from the drum on to a catcher band. When an imperfect cigarette is detected rod 31 operates piston 23 and moves it to the position shown in Fig. 1. Port 17A, which communicates with the holes 12, is thus put into communication with the atmosphere through depression 18, the recess 33 in the piston 23 and a hole 30 in the valve body 16 which is open to the atmosphere. The imperfect cigarette is thus allowed to fall away from the drum.

Title: A method for producing sterile, highly-active plasminogen
IPC: C12N9/68
Filed: 1957-09-20
Abstract: A method of producing sterile, highly active plasminogen substantially free of inhibitors comprises subjecting an aqueous solution of plasminogen having a pH of not less than 3 and not greater than 6.5 and an ionic strength not greater than 0.3 to a heat treatment which would normally cause the plasminogen to lose its specific activity.  The heat treatment specified is heating at about 60 DEG C. for about 10 hours.  Preferably the amount of plasminogen in solution is not more than 10% by weight.  After the heat treatment step the pH of the solution may be adjusted to between 6.5 and 8 while maintaining the ionic strength below 0.3 and the solution sterile filtered and lyophilized to yield a solid highly active plasminogen.  The process is particularly useful in treating plasminogen obtained from human blood, in that hepatatis virus, which often contaminates such a product, is destroyed.  A method by which the activity of plasminogen can be determined is described.

Title: Monophonic-Stereophonic Automatic Switching Circuit
Inventor: RECKLINGHAUSEN DANIEL R VON
IPC: H03D1/22
Filed: 1966-07-04
Abstract: 1,157,673. Stereophonic radio receivers. H. H. SCOTT Inc. 4 July, 1966, No. 29914/66. Heading H4L. Means are provided for switching a radio receiver automatically from monophonic to stereophonic reception on receiving the corresponding type of signal. As shown, the composite stereo signal derived from receiver 2 is amplified at 4 and supplied to filters 6, 8, 10, 12. Filter 6 selects noise signals above say 75 kc/s., filter 8 passes the composite stereo signal, filter 10 selects a monophonic signal and filter 12 selects the 19 kc/s. pilot signal. If a monophonic signal is being received, filter 8 will supply a signal to the conventional stereo demodulator 14 and monophonic signals will be supplied to diodes D 1 , D 2  which, are reverse-biased to be non-conductive by the voltage at the anode of valve 1<SP>1</SP> of a trigger circuit 1, 1<SP>1</SP>, both valves 1, 1<SP>1</SP> being conductive, so that these signals will not appear at the left and right output terminals. The monophonic signal passed by filter 10 is supplied to diodes D<SP>1</SP> 1 , D<SP>1</SP> 2  which are biased to conduct and pass the signals to the left and right outputs. On the reception of a stereophonic signal, the 19 kc/s. signal from filter 12 is supplied via amplifier 16 to synchronize the subcarrier regenerator 20 for the stereo demodulator and is also rectified at 22 to modify the bias on valve 1 relative to a reference 22<SP>1</SP>. This maintains valve 1 conducting but cuts off valve 1<SP>1</SP> to reverse the biasing of diodes D 1 , D 2  and D<SP>1</SP> 1 , D<SP>1</SP> 2  so that the left and right stereo signals are supplied via diodes D 1 , D 2  to the respective outputs. At the same time a neon device N indicates that the receiver has switched to stereophonic reception. The neon N may be directly operated by the output of amplifier 16. The inter-station noise output from filter 6 is amplified by valve 1 and rectified at 25 to cut off amplifier 16. This ensures that the receiver is switched for monophonic reception during tuning or when tuned to a weak stereophonic station.
