Abstract: 1,088,019. Mincing machines. MOULINEX S.A. May 17, 1966 [May 25, 1965], No. 21938/66. Heading A4C. In a mincing machine in which the drive shaft 18 passes through a hole in the bottom of the generally cylindrical working bowl 10 seated on the drive housing, the hub 22 carrying sharpened blades 24 and 26 is drivingly connected to the driving spindle by helical splines on the later surface of the spindle engaging with correspondingly shaped clearance grooves in the surface of a central bore of the hub, the spiral angle of said splines and grooves lying between 20 and 40 degrees and the pitch being such that one rotation of the spindle in its normal direction of rotation fully engages the splines in the grooves. A handle 40 is formed on the hub. In the embodiment described the active edges of the blades comprise two rectiliner sections 44 and 46 joined by a curved section 42, the outer section being more extensively angled rearwards than the inner section and the span of the blades is 9/10 of the diameter of the bowl. The inner wall of the bowl is vertically grooved in its bottom portion. A removable cover 12 has a cylindrical skirt 78 engaging in a cavity 74 in the drive -housing to operate safety switches, one of which, 66, is shown in Fig. 1. The groove 74 also houses springs 86, 88 and 90 urging the cover upwards so that its weight alone is not sufficient to operate the safety switches. The cover or the bowl may be shaped to form moulds for croquettes.

[Also in Group XX] Apparatus for measuring surface characteristics comprises a cylinder 39 on which the surface F to be investigated or a plastic impression thereof is draped. The crest of the surface is illuminated by a lamp 10 to project a magnified image of the surface profile on to the screen 18. Two adjacent slits in the screen 18 illuminate the photo-cells 19, 20, with light -from two adjacent portions of the surface profile, the photo-cells being connected to give an output e.m.f. proportional to the difference in shadow size at the two slits. The cylinder 39 is traversed across the light beam 14 by means of a screw 36 actuated by the motor M through a belt 34 and a gear train 35. The output of the photo-cells which is integrated by a computer and the total indicated by the voltmeter 24 thus represents the mean absolute successive difference or the mean square successive difference, along the profile, according to the computor circuit employed, and is a measure of the surface wrinkles. The invention is described with reference to the evaluation of "drip dry" fabrics and tensioning means, Figs. 4, 5 (not shown), are describedto compare the mean absolute successive difference with and without wrinkles.

Abstract: 228,454. Ringquist, J. M., and Head, Wrightson, & Co., Ltd. Aug. 13, 1924. Discharging.-A clay gun F for use in stopping the tapholes of blast furnaces is mounted on a track D on a jib arm C, and is positioned for operation by rotation of a sheave, which first swings the jib arm and then advances and depresses the gun. The arm C and a double sheave H, G are loosely mounted on a shaft A carried by brackets B<1> secured to the furnace column B. Around the sheave H passes a main operating-rope, while to the sheave G are secured the ends of two ropes J, K, which pass over pulleys L, L<1>, L<2> and axe secured respectively to the rear and front ends of the guncarriage E. Beneath the jib arm is a spring- pressed rod N, one end of which engages a stop E<2> and locks the carriage on the track D until the movement of the arm allows the opposite end to pass into a socket P<1> in a sleeve P fast on the shaft A. This locks the arm and releases the carriage, which travels forward on the track. On reversing the direction of rotation of the sheave H the carriage is withdrawn, and near the end of its movement on the track D it engages a bell-crank lever Q and withdraws the rod N from the socket P<1>.
