Title: Lithium iodate crystals - with improved transparency - for electroacoustic conversion of laser beams
IPC: C01B11/22
Filed: 1970-05-27
Abstract: LilO3 crystals have absorption coefficient for light of wavelength 0.347 mu, with electric field vector perpendicular to c-axis of crystal, in image alpha = 1.2 to alpha = 0.05 cm-1, alpha being calculable from formula:- (in which d is crystal thickness, Io and I are incident and emergent light intensities and n is refractive index of the ordinary ray). This type of crystal is used as electroacoustic converter, esp. in appts for producing second harmonic of laser beam, in which it is oriented at fixed phase-matching angle to c-axis in direction of laser beam. Crystals with improved transparency are prepd. by slowly withdrawing crystal from pure LiIO3 soln. They give relatively good yields of energy conversion of laser radiation.

Title: Continuous strut bending machine - with endless chain mounted bending tools
IPC: B21F1/04
Filed: 1971-02-01
Abstract: In the bending of multiple struts from continuous lengths of material, the material is moved through a machine in which bending tools are swivel mounted on an endless chain and are positioned by guide elements. The endless chain moves in steps and the bending tools are applied simultaneously after each chain step, which is half the length of a strut profile, the feed material being moved syncrhonously. The tools act such that the workpiece is bent in one direction only in each working stroke. The machine permits the mfr. of long lengths of struts. The process ensures that no flexing of the strut takes place during forming of the struts, which are intended as grid supports for reinforced concrete structures.

Title: Methanol synthesis with improved reboiler heating
IPC: C07C29/151
Filed: 1971-04-07
Abstract: In a catalytic MeOH synthesis where a fluid hydrocarbon is steam reformed to give a high temp. synthesis gas stream (g.s.), this g.s. is cooled in a steam boiler to an intermediate temp. by a first heat exchange (h.e.) with water, and then cooled further to condense the water. The resulting g.s. is compressed and combined with a recycle g.s. to form a synthesis feed g.s. This is heated by a third h.e., passed to a catalytic MeOH-synthesis at elevated temp., and press. cooled by the third h.e. and further cooled by a fourth h.e. to condense the MeOH. The crude MeOH is separated at elevated press. The residual gas is divided into a purge g.s. and the recycle g.s. The MeOH is distilled under reduced press. in distillation columns fitted with lower reboilers. These reboilers are heated by cooling the intermediate temp. g.s. by passing through at least one, passing a liquid through the fourth h.e. which is heated and passed through a second reboiler, and recycling the cooled liquid.

Title: Double valve for coaxial pipes - has rotating operating disc with sealing plates and method of adjustment
Inventor: BACHL HERBERT PROF DR ING
IPC: F16K3/00
