Abstract: ABSTRACT OF THE DISCLOSURE    Glutarate-containing polyesterpolyols are produced by reaction of primary and/or secondary diols and/or polyols with dimethyl glutarate in the presence of a transesterifacation catalyst which does not have deleteri-ous effects on the behavior of such polyesterpolyols when they are employed in the subsequent preparation of poly-urethane compositions, nor on the properties of such derived polyurethane compositions.  The ratios of reac-tants are controlled so as to obtain essentially complete conversion to hydroxyl terminated compositions of pre-determined molecular weight and hydroxyl functionality. An important modification of the above polyesterpolyols is that in which they are subsequently used as polyol intermediates in the preparation of glutarate-containing co-polyesters.  These hydroxyl terminated glutarate polyesters and co-polyesters are used to produce a wide variety of polyurethane compositions which exhibit unexpected and extremely useful combinations of properties. The polyurethane compositions are useful us elastomers, foams, coatings,  adhesives, thermoplastics, plasticizers, etc.

Abstract: ABSTRACT              A luminescent screen consisting of one self-supporting monocrystalline body and having a luminescent surface layer. Such screens can be ex-posed to radiation of a larger energy than was usual so far in phosphos screens. In addition the resolving power is very large since no particles with limited dimensions are present. Such screens may be used as n moving or stationary very bright light source or for displaying very bright pictures suitable for projection on a projection screen.

Abstract: ANIMAL TRAP     ABSTRACT OF THE DISCLOSURE:       An animal trap having a pair of arcuate rod-like jaws that are biased to a closed position with a torsion coil spring.  One jaw is integral with a first rod attached to a base.  The other jaw is attached to a second rod pivotally mounted on the first rod with a sleeve.  The coil torsion spring is concentrically located about the sleeve and rod and has a first end engageable with the base and a second end engageable with the second jaw so as to bias the jaws to their closed position.  A trigger mechanism having a trip plate cooperating with a pivotal arm is used to releasably hold the jaws in their open position.  A member connected to the jaws engages the arm so that the biasing force of the spring will hold the trip plate in its set position.  When the trip plate is moved from its set position, the arm is released so that the spring will close the jaws.  In one form of the invention, the trap has two pairs of jaws that are concurrently biased to their closed positions with pairs of coil torsion springs.  A common trigger mechanism holds both pairs of jaws in their open positions.

Abstract: Compositions useful as surfactants in the emulsification of oils in aqueous media are obtained by blending two types of polyester which are the products of condensation of an alk(en)yl succinic anhydride with a polyalkylene glycol, the one type being derived from an anhydride in which the alk(en)yl group contains 40-500 carbon atoms, e.g. polyisobutenyl succinic anhydride, and the other type being derived from an anhydride in which the alk(en)yl group contains 8-18 carbon atoms, e.g. dodecenyl succinic anhydride.  The compositions are superior in effect to either type of polyester separately, in enabling emulsions of high stability to be produced with a low energy input.

Abstract: UNIVERSAL JOINT                  Abstract of the Disclosure A universal joint for power drive tools and the like.          The universal assembly includes a means for connection to a tool and a means for engaging the nut or a head of a fastening member, such as a bolt.  Articulation of the universal is accomplished by means of a quadrified ball in a square socket.  The head of the ball retains its spherical form, and the base of the socket is spherical in shape to accom-modate the ball head.  The four sides of the quadrified ball do not intersect thereby retaining the spherical configura-tion of the ball at the corners.  A unique ball spring preloads the socket.  The resulting combination is ideally suited for power drive tools wherein the forces generated are high, and the rotation is rapid.

Abstract: ABSTRACT        When a machine element having a large mass is given a reciprocating movement the recurring changes in speed as well as direction of movement bring about that very great driving forces must be supplied, which cause varying stresses on the driving unit. In case the movement path of the machine element is more or less vertical the force of gravity causes extra stresses on the machine element. These difficulties are overcome in accordance with the invention by the help of a spring system which on the one hand equalizes the effect of the force of gravity on the machine element, on the other hand compensates the arising mass forces by absorbing, storing and emitting energy following the move-ment of the machine element. Hereby the amount of applied driving force is reduced, so that shocks and vibrations occurring during the driving are effectively reduced.

Abstract: ABSTRACT:     Arrangement for checking the synchronisation of a data signal receiver. When frequency division is used as part of the clock signal regeneration process, a phase ambiguity may occur. To eliminate this am-biguity use is made of a monitoring device. A frequently used criterion is derived from the information which is contained in the zero-crossings of the data signal. A problem is presented by the signal distortion. In the present monitoring circuit the data signal is sampled twice in each symbol interval and a reliable criterion is obtained by integration of the amplitude differences of the samples.         Used in baseband data transmission, in the band from 0 Hz to twice the bit frequency.           Fig. 3.

Abstract: ABSTRACT A turret mounted series of photocomposing disc fonts wherein the turret has a series of disc hubs all having a different elevation in order that the disc members may be bunched together in overlapped relationship and hence occupy a minimum area within the photocomposing machine.  The turret is rotated to select a particular disc for insertion into an optical system, and is advanced or retracted along its own axis according to the elevation of the particular hub selected in order that the optical system of a photocomposing machine may remain stationary, and the particular disc member be brought to the proper focus position within the optical system.  The advance in the art is primarily in the placement of the discs in overlap relationship and then advancing or retracting the turret in order to accomplish proper positioning of the disc as opposed to the concept of the prior art in keeping all discs on one plane and then rotating the turret to bring each disc in turn into the optical system.
