[Class 97 (i)] A stereogrammetric plotting apparatus for use with photographs taken with inclined axes comprises two pairs of rods each consisting of an image-space rod l<SP>2</SP>, l<SP>4</SP>, Fig. 1, and an objectspace rod l<SP>1</SP>, l<SP>3</SP> which pass through the centre of projection P through which also passes an auxiliary axle a-b rotatably carrying an axle e to which the rods l<SP>1</SP>, l<SP>2</SP> are pivoted and carrying a slide n connected by links q<SP>1</SP>, q<SP>2</SP> to the rods l<SP>1</SP>, l<SP>2</SP> so as to bisect the angle therebetween, the rods and slide rotating with the axle e about the axle a-b and the rods and axles rotating about an axis coinciding with the image-space rod l<SP>2</SP> which carries one of the photographs V<SP>1</SP>, V<SP>2</SP> viewed in the stereoscope T, so that the solid angles described by the rods l<SP>1</SP> and l<SP>2</SP> are equal, the angle between the rods being adjusted to the angle of convergence of the photographs. As shown in Fig. 3, the axle a-b has bearings g, h rotating in an azimuth piece i mounted in a ring k for rotation about the normal axis of the rod l<SP>2</SP>. A worm m adjusts the angle between the axle a-b and the plane of the piece i and hence adjusts the angle between the rods l<SP>1</SP>, l<SP>2</SP>. The axle e, Fig. 3, carries journals to which the rods l<SP>1</SP>, l<SP>2</SP> are pivoted. In plotting the rods are adjusted by rotation about the axle a-b and by rotation of the azimuth piece i to move different portions of the photographs V<SP>1</SP>, V<SP>2</SP>, connected to the arms l<SP>2</SP>, l<SP>4</SP> by universal joints, past the stereoscope T. Alternatively, the photographs may remain stationary and the end prisms of the stereoscope be moved by the rods.

Title: Improvements in or relating to methods of preparing new compositions of matter and the new compositions of matter resulting from said methods
IPC: C09F1/00
Filed: 1947-10-13
Abstract: Cyclopentadiene is thermally reacted with rosin, abietic acid, polymerized rosin or rosin esters.  The products are soluble in drying oils and the usual paint solvents or thinners and are useful for surface coatings.  The cyclopentadiene may be used as the monomer, or dimer, or as a cyclic Diels-Alder polymer, or fraction rich in these materials, e.g. certain cuts of crude solvent naphtha obtained in cracking hydrocarbons may be used. The reaction temperature employed is preferably between 400 DEG  and 650 DEG  F., the pressure being adequate to maintain the reactants in liquid phase.  Air and solvents may or may not be present in the reaction mixture.  If desired, cyclopentadiene or its Diels-Alder polymers may be heated for a short time and the rosin component then added and the reaction completed.  Products possessing high acid numbers may be reacted with glycerine, pentaerythritol or other polyhydroxy compounds.  In example (1) cyclopentadiene is heated for 3 hours at 525 DEG  F. with abietic acid.  The product is soluble in aromatic and naphtha solvents or in raw or bodied linseed oil.  In examples (2), (3) rosin replaces the abietic acid and naphtha is present as a solvent.  An atmosphere of nitrogen is used.  Example (4) is similar. In example (5) the cyclopentadiene is heated alone before the rosin is added.  Example (6) employs methyl abietate and examples (7), (8) polymerized rosin.

An automatic exchange system is arranged to provide two (or more) separately set-up connections between inlets and outlets. As described the invention is applied to cross-point (e.g. reed-relay) systems for setting up four-wire connections between incoming and outgoing junctions. In one embodiment, Fig. 1 (not shown), ordinary subscribers' lines are connected to both sides of a switching network and a single path, for local-local or local to junction calls, is used; but for calls between incoming and outgoing four-wire junctions two separate paths for the " go " and " return " paths are set up independently by a route selector operating on a one-at-a-time basis. In a second embodiment, Fig. 2 (not shown), local subscribers are connected to one side only of a switching network having on its other side interconnecting - link circuits and for local calls a two-wire connections are effected through the network from the link to the called subscriber and from the link to the calling subscriber. Four-wire connections between junctions may be established either by using a link and establishing two four-wire connections as described above between the link and the incoming junction and between the link-and the outgoing junction. In a further embodiment, Fig. 3 (not shown), in which connections have to be established between a register connectable to the incoming side of a network and a digit sender connected to -the outgoing side of the network, a four-wire connection is first established to the outgoing junction to which a sender is then connected. Then for the duration of outgoing digit sending only, a further four-wire connection is established through the network between register and digit sender. This enables eight wires to be available for signalling between register and digit sender.
