Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to an improved valve gated injection molding system in which the heated nozzle has a nose portion which extends through a cylindrical opening in the cavity plate to the cavity.          The valve gate extends through the nose portion and is tapered so that the forward face of the nose portion can be machined to a predetermined length to provide a gate of a particular size.  This has the advantage of improving heat transfer to the gate area and reducing the accuracy required of the moldmaker in that both the valve pin and the matching seat in the gate are provided by the manufacturer.          Furthermore, each size of nozzle can be adapted for several different gate sizes which reduces manufacturing and inventory costs.

Abstract: ABSTRACT               Voltage is dropped across the variable resistance of a gas responsive sensor to obtain a control voltage which is compared to a ramp waveform reference to cause the comparator to apply pulses to an SCR which supplies corresponding charging pulses to the battery.  Another embodiment uses the sensor resistance variation to decrease the current on the base of a transistor which controls the current supplied to the battery.

Abstract: ABSTRACT OF THE DISCLOSURE       A setting tool is shown of the type adapted to be made  up  in  a  pipe  string  for  releasably  engaging a setting  sleeve  in  a well bore.   The  setting  tool  is designed to set a liner hanger using right hand as well as left hand rotation and is released from the setting sleeve  using  right  hand  rotation.   A  plurality  of retractable,  spring loaded torque fingers carried on a torque collar are used to transmit torque to the setting sleeve but are moved into a retracted position after the setting sleeve is released to avoid damage to the torque fingers.   A plurality of  splines  and  a  splined  ring within the torque collar are used to latch the tool in the running-in position to perform well bore operations, such as hanging a liner.  The splines and splined ring have  specially  mating  surfaces  which  form  a  key arrangement  to  facilitate  reinsertion  of  the  splines within the splined ring for subsequent operations as the tool is manipulated between the running-in and weight set down positions.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method for preparing metallic acid-esters useful as  catalysts, finishing agents or bonding agents, in which titanium, zirconium or hafnium are present as metal atoms.  The method is characterized in that halides of these metals are caused to react with organosilane-esters, to produce the corresponding metallic partial esters.  If alkyl-esters are used as organosilane esters, it is possible to obtain metallic-acid-partial-esters with three ester-groups.  If organosilanearyl-esters are used, complete esterification of the metal halides may even be achieved.          According to the invention, the metallic-acid-partial-esters are produced in very pure form and may be selectively separated in a very simple manner from the mixture obtained.          The metallic-acid-alkyl-esters that are so obtained, may be  very easily esterified, in a manner known per se, to produce the corresponding metallic-acid-tetraalkyl-ester in very pure form.

Abstract: Abstract:    An improved control system ensures more effective utilization of the frictional force between the wheels of rolling stock and the rails.  From a peripheral velocity vM of a driving wheel and a vehicle velocity v, the rate of change .DELTA.vs/.DELTA.t of the relative velocity vs with respect to time is obtained.  The rate of change .DELTA.f/.DELTA.t of the traction force f produced in the driving wheel at that time is obtained from a detected armature current of a motor driving the driving wheel.  The driving torque produced by the motor is so controlled as to decrease when the polarities of the rate of change of the relative velocity and that of the traction force are different from each other.
