Abstract: ABSTRACT         The present invention relates to the preparation of titanium disulfide and more particularly to the production of stoichiometric titanium sulfide having a high degree of crystalline perfection and a controlled particle size by directly reacting metallic titanium and elemental sulfur. Particulate titanium is heated to a reaction temperature of between about 475°C and about 600°C, and the heated titanium is contacted with an atmosphere having a sulfur partial pressure substantially equal to the equilibrium sulfur partial pressure over titanium disulfide at the reaction temperature to form titanium disulfide, the titanium and sulfur being in substantially stoichiometric amounts.  The heated titanium is held at the reaction temperature to homogenize the titanium disulfide.  The stoichiometric titanium disulfide so produced is particularly useful as a cathode material in electrochemical cells, since crystal imperfections which would reduce the effectiveness of the titanium sulfide as a cathode material are minimized.

Abstract: ABSTRACT           Disclosed is a rotary sliding gate valve for metallurgical containers, in particular steel ladles, having a stationary part which includes a re-fractory bottom plate adjacent which is a rotatable part including a ring mount mounted on the stationary part and a refractory sliding plate resting against the bottom plate.  The rotatable part of the valve includes a housing partially defined by a rigid cover removably mounted on the ring mount.  A pressure plate which receives the sliding plate is located inside the housing. The pressure plate is in direct rotary engagement with the ring mount and is supported on the housing, preferably on the cover, by spring members.  The contact pressure of the sliding plate against the bottom plate is therefore independent of the rotary movement, the force being applied directly to the sliding plate.  In order to change plates it is merely necessary to remove the housing cover, the rotary drive means remaining permanently engaged on the ring mount.

Abstract: A COMBINATION CREEPER GEAR AND CONTROL SYSTEM FOR A TRANSMISSION              Abstract of the Disclosure This invention relates to a combination creeper gear and control system for a transmission having a range selector gear followed by a change speed gear.  The combination comprises an engine-driven drive shaft connected through a creeper gear mech-anism to an input shaft which extends into the transmission.  The creeper mechanism comprises a drive gear mounted on the drive shaft, a driven gear mounted on the input shaft and a lay shaft aligned parallel to both the drive shaft and the input shaft.          The lay shaft has a compound gear mounted on it which includes a first and a second gear.  The first gear meshes with the drive gear and the second gear meshes with the driven gear.  The combi-nation further includes a synchronizer located between the drive gear and driven gear which is selectively engageable between a direct mode and a creep mode.  In the direct mode, the drive shaft is directly connected to the input shaft, while in the creep mode, the drive shaft is connected to the input shaft by way of the compound gear.  In order to activate the creeper mechanism, a selector control means is attached which consists of a first and a second shift rod and a locking pin movably posi-tioned between the two shift rods.  The first shift rod is associated with the creeper gear mechanism while the second shift rod is associated with the range selector gear within the trans mission.  The locking pin controls the movement of the first and second shift rods such that the creep mode cannot be selected when the range selector gear selects a higher speed range, but which can be selected in either a low-speed forward range or a reverse range of said range selector gear.

Abstract: ABSTRACT OF THE DISCLOSURE           An electric kettle having an electrical immersion heater and a set of switch contacts.  The immersion heater comprises a metal sheathed element permanently mounted on a metal head so as to produce a hot spot on the head and a dry overload responsive actuating mechanism is provided responsive to overheating of the hot spot to open the switch contacts.  The dry overload mechanism is disposed between the mounting and the head so that a bimetal device incorporated in the mechanism abuts the hot spot, such bimetal device having a first movable member which extends to a first of the switch contacts.  A steam responsive actuating mechanism is also provided and actuates a second movable member which extends to a second of the switch contacts.  By providing a respective movable contact for each of the dry overload responsive actuating mechanism and the steam responsive actuating mechanism, each mechanism can b designed or modified without compromise or restriction imposed by the design of the other.  Such design also prevents the buildup of cummulative manufacturing tolerances in one actuating mechanism being compounded or affected by the tolerances in the other mechanism and removes the need for two respective switches and the alternative disadvantages and limitions inherent in arranging both actuating mechanisms to operate one movable contact either directly or through the on/off mechanism of a switch.

Abstract: PP39?     TITLE SELECTOR VALVE FOR ANESTHESIA MACHINE                                      ABSTRACT A selector valve for providing a choice of one of two vaporizers for use in administering an anesthetic to a patient is disclosed in connection with a manifold for receiving the vaporizers. The selector valve has three positions, wherein the user can utilize one of two vaporizers or place the valve in an off position when neither vaporizer is in the circuit providing a flow of gas to the patient. One of the features comprises a positive position means where the selector valve cannot inadvertently be placed in any position intermediate any  two of the three positions so that only one of the three defined positions may be selected.  Also, in the off position, leakage is prevented into the gas stream to the patient of anesthetic vapors from either of the vaporizers mounted to the manifold by closing both the inlet to and the out-let from both such vaporizers.  Further, in the event one vapor-izer is selected for use, the remaining vaporizer also has its inlet and outlet closed such that no inadvertent leakage of anes-thetic vapor from the "off" vaporizer can reach the path of gas proceeding through the "on" vaporizer and selector valve to the patient. The means of connection and sealing means within the se lector valve further are designed to insure that any seal leakage due to wear will cause the leaking anesthetic vapors to vent to atmosphere and not leak into one of the other active gas paths to the patient.

Abstract: ABSTRACT       A  digital  time  base  for  producing  sample  clock pulses  is  provided  with  a  control  circuit  to  permit coherent  switching  from one  sample  rate  to another. A plurality of predetermined sampling rates and number of samples  to  be  acquired  at  each  rate are  stored  in  a memory.  The predetermined  sampling  rates provide  count moduli to a counter which divides the frequency of a base clock in accordance therewith to produce the actual sam-ple  clock pulses.  A  counter  is provided  to  count  the sample  clock  pulses,  and  when  the  desired  number  of pulses are generated, a next succeeding sampling rate and number of  samples to be acquired are accessed from the memory. The rate  switching to change the count modulus takes place between last sample clock pulse generated for a particular  sampling rate and the next succeeding base clock pulse so that such switching is coherent.
