Abstract: ABSTRACT OF THE DISCLOSURE    A heat insulating panel for use in construction of building structures such as a built-up roof.  The heat insulating panel comprises first and second oppositely disposed surfaces with a core therebetween comprised of phenolic foam material. The first surface of the panel includes a thin layer of reflecting material over substantially the entire surface thereof to reduce the heat conveyed to the core due to sun radiation when the layer of reflecting material on the panel is exposed to sun radiation during construction of the building structure, This reduction in the heat conveyed to the core reduces curling or warping of the panel, before application of finishing materials, such as bituminous roofing material, over the panels.  There is also disclosed a method of constructing a building structure with such heat insulating panels.

Abstract: A B S T R A C T         An optical communication cable for the transmission of light comprises one or more than one optical cable element housed in a flexible tube of insulating material, the bore of the tube having regard to the cross-section of the or each element being such that at least one elongate space is formed between the element or elements and the tube.  The or each optical cable element comprises an extruded elongate body of insulating material having a bore in which is loosely housed at least one optical fibre having a diameter less than that of the bore.  The bore has a smooth continuous boundary wall and is of uniform transverse cross-section throughout its length.  To provide reinforcement for the element, two separate elongate reinforcing members are embedded in the extruded body throughout its length and are arranged on opposite sides of and parallel to the bore. The or each optical cable element may be loosely housed in the tube or it may be bonded to or integral with the wall of the tube.  As compared with optical communication cables hitherto proposed, the optical cable is simple and inexpensive and because limited movement of the optical fibre can take place within the optical cable element, there is substantially less risk of fracture of or damage to the optical fibre during manufacture and installation of the cable.

Abstract: TITLE:  SOUND INSULATING SUPPORT FOR PLUMBING PIPES     ABSTRACT    A sound insulating support member for isolating a plumbing pipe or other tubular member from a support surface includes an insert member formed of a material substantially incapable of transmitting sound vibrations and sized to be capable of encircling the pipe or tubu-lar member.  The insert member fits within a sleeve member which is formed of a semi resilient material capa-ble of maintaining its shape at rest but capable of being flexed when subjected to a force  Both the sleeve member and the insert member contain a slit.  The insert member is retained within the sleeve member such that the slit of the insert member is aligned with the slit of the sleeve member and when both the sleeve and the insert are open the pipe or tubular member can be in-serted through the slits and the sleeve and insert close around the pipe or tubular member to cradle the tubular member within the insert which in turn is fixedly held within the sleeve.  A support structure is attached to the sleeve which is capable of being fixedly attached to the support surface.  This holds the sleeve and the pipe or tubular member contained within the insert fixedly locked to the support surface yet sound isolates the pipe from the support surface.

Abstract: ABSTRACT OF THE DISCLOSURE       The improvements in longline fishing systems dis-closed herein include improvements in the art of baiting long-lines, improvements in a baiter and a bait cutting mechanism, improvements in a fish hook and improvements in a magazine for storing hooks during baiting and longline shooting.  The im-provement in the baiting method provides that the steps in the baiting include the locating of adjacent hooks of a longline in a side-by-side laterally spaced relationship and the retain-ing of the hooks in a gang in a fixed position with respect to one another and simultaneously hooking the gang of hooks into bait while the gang of hooks are retained in the fixed relation-ship.  The improvement in the fish hook includes the provision of a body having a shank portion at one end thereof upon which a spacer is mounted.  The spacer has at least one lateral pro-jection extending therefrom whereby a plurality of hooks can be arranged in a side-by-side relationship with their head portions spaced by engagement of the projections of adjacent spacer means.  The fish hook baiter comprises a hook support for supporting a gang of hooks in a side-by-side spaced relationship, a bait support for supporting bait during hooking and guide means interconnecting the bait support and the hook support to permit relative movement therebetween along a baiting path whereby bait supported on the bait support is applied to each of the hooks in the gang of hooks.  The fish hook storage magazine in which the hooks may be supported for baiting and shooting comprises a frame which has a slipway opening inwardly from one end thereof.     The slipway has upwardly and downwardly opening passages ex-tending longitudinally inwardly from the one end and opposite sides of the slipway are adapted to slidably mount a fish hook for movement along the slipway whereby a plurality of fish hooks may be mounted on the slipway in a side-by-side sliding relationship.

Abstract: A CIRCUIT FOR TRANSFERRING SIGNALS       Abstract of the Disclosure A time slot interchanger is disclosed for selecting and buffering digital signals between buses.  In one embodiment, a clock is used to generate time signals corresponding to time slots of the first bus.

The enable signal has a time identity with a first bus time slot and a physical identity with a particular second bus time slot.  The enable signal is used to gate into a second memory the time slot signal associated with the time identity at the storage location in the second memory corresponding with the particular time slot of the second bus associated with the enable signal. The signal samples are then sequentially removed from the second memory.  The arrangement is particularly useful in forming conferences in a distributed digital time division system.
