Abstract: ABSTRACT OF THE DISCLOSURE         The gallery walking lining consists of arch segments connected in alternate pairs by means of tie rods disposed near to the floor.  Each arch segment is composed of two arch elements connected at a crown and terminating in supporting hydraulic cylinders.  In the arch segment there are slidably mounted roof-support elements connected to hydraulic cylinders.          Extending of the supporting hydraulic cylinders causes a preliminary spragging of the arch segment in the heading.  Final spragging is effected by means of the hydraulic cylinders which press the roof-support elements to the surface of the heading.  Displacing of the arch segment is performed after withdrawing it by suspending on a rail carried in adjacent spragged arch segments.  The displacing of the withdrawn arch segment on the rail is facilitated by means of runners.

Abstract: ABSTRACT OF THE DISCLOSURE              Triglyceride oils are bleached rapidly and efficiently in a continuous system wherein a stream of the oil is preheated to bleaching temperature and is introduced into a mixing zone in such manner as to provide a swirling motion, bleaching absorbent containing moisture is added to the surface of the swirling hot oil and water vapor or steam derived from the moisture in the absorbent forms a protective atmosphere above the surface of the oil to protect it from oxidation.  The oil-absorbent mixture is pumped continuously from the mixer to a bleaching zone consisting of one or more static mixers, which may be unobstructed pipe sections, under flow conditions pro-viding an average residence time of approximately one minute.  The flow regime in the bleaching zone may be laminar or turbulent.  Optionally, the oil-absorbent mixture may flow continuously from the mixing zone to a vacuum dryer where it is dearated and dried to optimum moisture content for bleaching prior to being pumped to the bleaching zone.  Total time through the system may be in the order of less than three minutes.  The advantages include simplicity of the operation, savings in time and ease of changing feedstocks.

Abstract: ABSTRACT OF THE DISCLOSURE     An acoustic code transmitter in the form of a hand held device provides remote control for a telephone answering machine by means of tone signals transmitted over a telephone liner.  A receiver in the answering machine is provided for recognizing the transmitted tone signals in order to cause reproduction of the messages which have previously been recorded on a storage tape in the answering machine, via the telephone line, to the caller.  The code transmitter has switching elements for the production of tone signals of unitary duration and frequency, and for the selective pro-duction of different sequences of these tone signals.  A first selectable sequence is a code signal for the repro-duction or erasure of the messages recorded in the answering machine; a second sequence is a command signal for the con-tinuation of the playback; and a third sequence is a control signal for the rewinding of the storage tape.  The receiver has switching elements for recognition of the received sequences of the tone signals, in order to correspondingly control the recording tape.  In addition there exists in the answering machine several signal generators, connectable to the telephone line, for the production and transmission of announcement signals which acknowledge the received code signal to the caller, which indicate the end of the playback interval and the end of the recorded messages, and which provide an erasure inquiry to the caller.  The system enables reliable and rapid remote inquiry to the answering machine, and may be made without great expense and without frequency equalization utilizing integrated electronic switching means.

Abstract: Abstract:            A miniature electronic timepiece whose analog-display time-indicating hands are driven by the rotor of a stepping motor actuated by low-frequency periodic timing pulses derived by frequency division from a high-frequency crystal-controlled time base.  The motor, in addition to a stator coil wound on a core, includes an auxiliary coil wound on the same core to define a transformer whose primary is the auxiliary coil and whose secondary is the stator coil.  To power the electronic watch, a voltage at a predetermined level is required, this being supplied by a converter formed by an electronic chopper interposed between the primary of the transformer and a d.c. source whose output is at a different voltage level.  Thus the d.c. voltage applied to the primary is periodically interrupted, the resultant a.c. voltage yielded by the secondary being rectified to provide the desired power voltage.
