Abstract: ABSTRACT OF THE DISCLOSURE           A telephone answering system is provided for responding to telephone messages received over a telephone line.          The system includes a first magnetic tape mechanism having a recorded announcement thereon which is transmitted over the telephone line during a time interval T1 in response to a telephone call, a switching means coupled to the first magnetic tape mechanism to be activated to a particular state for the duration of the T1 time interval, and a second magnetic tape mechanism for recording messages received over the telephone line during a second time interval T2 following the time interval T1.  A tone sensing circuit is included in the system, and is coupled to the telephone line for sensing a tone signal of a predetermined frequency received over the telephone line and for providing an output signal for response thereto.  A first control circuit is connected to the switching means and to the tone sensing circuit and responds to the output signal produced during the T1 time interval, and when the switching means is actuated to the particular state for causing the first magnetic tape mechanism to stop and for causing the second magnetic time mechanism to rewind to a reference position.  A pulse generator is coupled to the second magnetic tape mechanism for producing pulses during movement of the second magnetic tape mechanism.  A second control circuit is coupled to the pulse generator, and it responds to the termination of the pulses from the generator to cause the second magnetic tape mechanism to move forward and to transmit any messages recorded thereon over the telephone line.  Finally, a third control circuit is connected to the tone sensing circuit and responds to an output signal from that circuit corresponding to a second tone signal of said predetermined frequency received over the telephone line for stopping the motion of the second magnetic tape mechanism and for restarting the first magnetic tape mechanism so as to cause the first magnetic tape mechanism to complete the T1 time interval.

Abstract: METHOD FOR THE PRODUCTION OF            Abstract of the Disclosure Disclosed is an advantageous method for producing trans-4-aminomethyl cyclohexane-1-carboxylic acid by heating and isomerizing cis-4-aminomethyl cyclohexane-1-carboxylic acid hydrochloride or a mixture of cis-4-aminomethyl cyclo-hexane-1-carboxylic acid hydrochloride with trans-4-aminomethyl cyclohexane-1-carboxylic acid hydrochloride under the atmosphere of hydrogen chloride gas in the absence of a solvent. This method avoids a disadvantage of previous methods for producing this substance, namely that previously a combination of an isomerization step, to convert the cis compound to the trans compound, and a separation step for isolating the trans compound from the resulting cis/trans mixture, has been required.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved process  for preparing cycloalkanones and cycloalkanols from cycloalkylhydroperoxides.  Cycloalkyl-hydroperoxides are converted under the influence of a solid heterogeneous chromium oxide catalyst and the reaction mixture is stripped with a stripping gas which reduces the content of water which is formed in the reaction mixture during conver-sion.  As a result, the catalyst activity and selectivity is maintained.

Abstract: MAGNETIC BUBBLE DEVICES WITH CONTROLLED TEMPERATURE CHARACTERISTICS            Abstract of the Disclosure The temperature variation of the bubble collapse field of a class of garnet magnetic bubble layer materials is selected by control of octahedral site substitution during layer growth.  This permits the growth of layers, whose temperature dependence of critical magnetic properties more closely matches the temperature dependence of available bias magnet materials, resulting in extended operating temperature range and/or wider operating margins (with attendant improvement in manufacturing yield).  A preferred substitution species is lutetium, known as a dodecahedral site occupant, for which it has been determined that a significant and controllable octahedral occupancy can be produced by suitable choice of growth conditions.

Abstract: CASTING ASSEMBLY FOR STATOR COILS AND METHOD              ABSTRACT OF THE DISCLOSURE         The terminal portion of a winding end turn con-ductor which projects from the core member of a dynamoelec-tric machine is encapsulated in an epoxy pot ing compound by means of a casting assembly which comprises a detachable conformable pad, a plastic sleeve mold, and a portable vise.          The conformable pad is fitted about the terminal portion of the conductor to provide a temporary barrier to axial flow of the epoxy compound during casting.  The plastic sleeve is disposed around the terminal portion in a spaced relationship therewith and in an abutting relation with the pad to pro-vide a barrier to the radial flow of the epoxy compound during casting.  Clamping means such as a portable vise is fitted about the conformable pad and is tightened to esta-blish a compressive union at the interface of the conform-able pad and the terminal portion of the conductor to pre-vent leakage.  A pair of spring members hold the sleeve in abutting engagement with the surface of the conformable pad during the casting process.  In a preferred embodiment, a sealing compound is applied to the interface of the pad and the sleeve and also between the pad and the terminal portion of the conductor to prevent leakage.  After the epoxy com-pound has cured, the clamping means and detachable con-formable pad are removed from the assembly and can be reused to encapsulate other conductors.
