Abstract: ABSTRACT                  HOSE MANUFACTURE   A method of manufacturing a hose comprising a layer of polymeric material having an embedded reinforcement structure.  The hose structure is formed on a mandrel and the polymeric material is cured by passing the assembly through a curing unit containing heating fluid at a pressure greater than 100 p.s.i.         The use of pressures greater than 100 p.s.i. ensures the hose components are securely bonded to one another and avoids the use of a conventional outer lead sheath which is expensive and the fitting and removal of which considerably increases the cycle time.         Preferred heating fluids are salts, such as a eutectic mixture of sodium and potassium nitrates, a mixture of sodium nitrate and sodium nitrate or Cassell TR 155.  At the vulcanisation temperatures of 170 - 200°C used the temperature of the heating fluids is substantially independent of pressure. Pressures up to 500 p.s.i. can be used to achieve the necessary bonding of the hose components.

Abstract: ABSTRACT           The present specification discloses a method of making a silicon photoelectric cell, particularly solar cell, in which an N-doped Si-layer covered at one of the surfaces thereof with a metal coating serving as an electrode is coated on the other surface with a close network of Si-pyramide for providing an antireflex coating.  For making silicon photo-electric cells, particularly solar cells, a great number of process steps have been required up to now, which in itself necessarily involves considerable manufacturing expenses.  The specification discloses a manufacturing process for solar cells which compared with hitherto existing processes is much less complicated, and which with considerable reduced efforts can provide reliable and highly efficient solar cells, or photo-electric cells, in a very simple manner.  This object is achieved by, after the application of aluminum and silicon onto the other surface of the Si-layer for providing the antireflex coating, subjecting the Si-layer to a heating process to lower the eutactic temperature of the aluminum-silicon in an inert atmosphere until Si-pyramids coated with a thin Al film are formed and subsequently partially removing the thin Al film to form a comb-shaped electrode on the Si-pyramids.  According to the process of the present invention the semiconductor surface is covered with microscopically small pyramids and therefore a highly efficient antireflex and correspondly good light absorption properties result.  Due to internal multi-reflections of the long-wave light between the back and front of the photoelectric cell, the semiconductor surface covered with the pyramid network correspondingly improves the efficiency of the cell.

Abstract: LOAD BREAK SWITCH                           ABSTRACT         A compact load break switch having at least one vacuum interrupter connected between two terminals carried by respective insulating bushings through a current exchange assembly.  The vacuum interrupter is disposed within one of the insulating bushings, and a current exchange insulating housing having portions which extend telescopically into both  insulating  bushings,  provides  adequate  creepage distance through air  from the vacuum interrupter and the current exchange assembly to a grounded housing for the load break switch.  Also, a current transformer is disposed about the insulating housing to provide remote indication of the flow of fault current through the current exchange assembly.          The switch operating mechanism includes:  a torsion spring which when fully charged, is capable of opening and closing the switch several times;  a motor driven spring charging mechanism,  for fully recharging the torsion spring after each switch operation; a solenoid actuated latch mechanism which may be remotely actuated to open or close the switch; a lockout mechanism for preventing closure of the switch when the torsion spring has insufficient stored energy to open  the  switch  thereafter  without  being  recharged; auxiliary switches for remote indication of the position of the load break switch; and manually-opened mechanisms for recharging the torsion spring and operating the load break switch.

Abstract: ABSTRACT OF THE DISCLOSURE An offshore pipeline installation comprises a wellhead base and a pipeline anchor connected together to form a unit which is lowered onto a seabed.  The anchor is pivotably posi-tionable relative to the wellhead base about a vertical axis of a pilot tube.  A pin pile is inserted through the tube and into the seabed to isolate the pipeline anchor from the wellhead and wellhead base in relation to forces generated in anchoring a pipeline to the pipeline anchor.  The anchor is selectively positionable for alignment with pipeline means to be laid, and may include a socket mounted for pivotal movement about one or more, axis.  The socket is operable to receive pipeline means laid away from the anchor.  The anchor may further include a ramp which is inclined relative to horizontal.  The ramp is positionable generally laterally relative to the lay path of the pipeline means so that pipeline means laid upon the ramp gravitates downwardly toward clamp means at the foot of the ramp.

Abstract: TELEPHONE INSTRUMENT CONNECTION BLOCK   WITH REMOTELY ACTUATED LINE TEST          Abstract of the Disclosure A remotely actuated line testing connection block with modular jack is disclosed for installation and use to connect directly to a subscriber's telephone instru-ment.  The block is connected to the incoming tip and ring wires of the line and to ground and provides tests which closely emulate those performed by a field repair-man.  When a test voltage of a first polarity from a cen-tral office is applied across one of the tip and ring wires and ground, a capacitor is charged.  Upon release of the test voltage, the capacitor actuates a first switch which shorts the tip and ring wires together and may also ground them if a ground test option is selected. The capacitor also activates a second switch which dis-connects the user's instrument.  The first switch re-leases after about half of a test interval with the second switch releasing at the end thereof to restore normal line connections.  In addition to, or in lieu of the first and second switches, the test block may include a test signal generator driven by a second capacitor charged from a test voltage of reversed polarity.

Abstract: Abstract of the Disclosure Fan-shaped beams, sweeping angularly, substantially flatwise, across a solid angle space having the beam emitter at its apex, are modulated for transmission of special information to a selected one of a plurality of identically equipped bodies in that space.  Whenever beam radiation reflected from a body is detected at the emitter, distance to the reflecting body is measured on the basis of radiation out-and-back time.  If the body is at a distance for which special information is valid, the beam is modulated with such information for as long as its reflection from that body is received.  A complete beam sweep cycle has a pre-determined duration.  As a basic condition for acceptance of special information, a body must receive such information on all beams during a predetermined time interval of at least that duration.  As a further condition, a beam may be modulated with a characterizing sign  whenever it intersects two bodies substantially simultaneously, and special information will be accepted at the body only if at least one beam lacks the characterizing sign.
