Abstract: 1,132,444. Welding by fusion. UNION CARBIDE CORP. 23 Nov., 1965 [24 Nov., 1964], No. 49632/65. Heading B3R. [Also in Division H1] In a laser welding operation the intensity of the laser beam focused on to the metal workpiece is defined by the equation 3<C<9, K = thermal conductivity of metal, T b  = boiling point of the metal, T 0  = original temperature of the metal, E = radiation absorptivity of the metal at the wavelength of the laser beam, a= thermal diffusivity of the metal, # = duration of the laser pulse and d = diameter of the focused laser spot. By controlling the intensity of the laser beam in accordance with the above equation holes are drilled in the metal which are allowed to fill in with molten metal before excess vaporization occurs thus resulting in a weld bead having an appreciably greater depth. The intensity of the laser beam is controlled by means of the optical pumping sources, Figs. 1, 2, 3 (not shown), Division H1, pumping the laser.

Abstract: 1,097,484. Textile treating apparatus. TEXMA MASCHINEN G.m.b.H., [trading as GEBR. SUCKER], Dec. 16, 1964 [Dec. 21, 1963], No. 51161/64. Heading D1L. A device for adjusting the bearing pressure of a squeezing device for material in web form dependent upon the adjusting movement of a web speed-control member is influenced by a pulse generator controlled by the adjusting movement of the speed-control member. In the embodiment of Fig. 1, material F passes through a dressing trough 2, the excess liquid being squeezed out between cylinders 3, 4; the material then passes through a drying chamber 5 and is drawn off by cylinders 6, 7, 8 and wound on a beam 9. Cylinders 4 and 7 are driven by a variable gearing 10 which is in turn driven by motor 12 or motor 13 which determines the creeping speed and normal speed, respectively, of the web material F. The adjustment of the transmission ratio of the gear 10 is effected by an adjusting spindle 14 driven by a motor 15 through clutch 16, the motor being controlled from a switchboard 17. The spindle 14 is connected to a cam disc 40 which controls a motor 39 for setting a cam cylinder 30 in motion; the rotation of the cylinder 30 operates a switch 32 which controls a motor 20 operating a spring 22 bearing on the cylinder 3. The cam cylinder 30 is provided with a cam disc at one end thereof to ensure only whole pulses are transmitted to the motor 20; the direction of rotation of the motor 20 is determined by rotation-direction switches 47, 48 which cooperate with the cam disc 40 and spindle 14. In a further embodiment, Fig. 7 (not shown), the cam cylinder (30) is replaced by a time relay (50). A further modification, Fig. 11 (not shown), replaces the cam disc (40) and cam cylinder (30) of the embodiment as shown in Fig. 1 by a Ferraris mechanism (65), Fig. 12 (not shown), which is set in motion when the motor (15) is switched on. Reference has been directed by the Comptroller to Specification 858,668.

Title: Door control apparatus
IPC: F25C5/00
Filed: 1976-12-10
Abstract: A device for controlling the opening and closing movement of a duct seal door of an automatic ice maker which requires a regulator for slowing down the closing of the door. The movement of the door about its rotational axis is transmitted via connecting linkages to the closure regulator which comprises a rotor positioned within a stator housing. The rotor's movement is coupled to the connecting linkages via a one-way clutch which decouples the rotor when the door is being opened, and causes positive coupling therebetween when the door is being closed. Disposed within the stator housing in a fixed-volume compartment is a viscous fluid, such as silicone gum. The rotor and stator include opposed rippled surfaces between which the viscous fluid is coactively disposed. The fluid acts as an impedance to the motion of the rotor, which motion occurs only upon the closing of the door, to thereby provide a controlled slow closure thereof.
