Abstract: 1,231,369. Soot blowers. DIAMOND POWER SPECIALITY CORP. 15 April, 1970 [16 June, 1969], No. 17996/70. Heading F2N. In a retractable soot blower, a supply hose or conductor 34 to a drive motor 32, which is mounted with the blower tube 24 on a movable carriage 16, is helically wound between a fixed support 40 and a movable support 50 mounted with the motor, and is carried in a guide tube or trough 36 fixed to a frame 20. The tube 36, as shown, is of circular cross-section, closed at both ends, and has a longitudinal slot 48 in its base along which the support 50 slides. The trough, Fig. 4 (not shown), is of arcuate crosssection and has a series of holes longitudinally spaced in its base for removal of foreign matter, the movable support being above the trough. The tube or trough is made of, or lined with, a low friction plastics material. The conductor 34 supplies an electric, pneumatic or hydraulic motor 32 which, through gearing, extends or retracts the blower tube 24 whilst simultaneously imparting a rotary motion so that cleaning fluid issues from the blower tube's nozzles in a helical pattern for effective cleaning. The cleaning fluid supply to the tube 24 is fed through a control valve, Fig. 1 (not shown) actuated by the carriage travel so that the fluid only enters tube 24 when its nozzles are inside the heat exchanger or boiler.

Abstract: 1,232,080. Boots &c. PRIME MFG. CO. 10 Oct., 1968. No. 48144/68. Heading A3B. A machine for applying rib stripping R to the entire margin of an insole S includes a rotary insole support 12, feed feet 23, 24, a guide block 40 for the stripping R, a knife severing the stripping at the end of the operation and a feeler 60 which is moved by the end of the stripping first attached to the insole (Fig. 3) to actuate the knife. When the feeler 60 is moved it operates a micro-switch 65 (Fig. 3) which actuates a solenoid 32 (Fig. 1) which rotates a cam 30 (Fig. 8). The cam 30 has a surface 35 which contacts a roll 37 (Fig. 3) on the arm 44 which supports the guide block 40 to raise the guide block 40 and lift the stripping R away from the insole as shown in Fig. 3. Rotation of the cam 30 also shifts a rack 48 which, through cam slot 50 and roll 57, moves a support 26 against the stripping R, the rib engaging a slot 27 in the support as shown in Fig. 8. At the same time a crank arm 55 on the cam 30 shifts a knife blade 59 to sever the stripping R.

A centrifugal or, as shown, an axial-flow fan F driven by an electric motor M discharges air through flow straightening vanes 11 and a circular grille 17 which can be rotated by the motor through a reduction gear-box G and a clutch. The clutch comprises three leaf-springs 22 which when located as shown in notches in a ring 16 fixed to shaft O, cause the grille to be rotated. The clutch merely slips if the grille is restrained against rotation. Disengagement of the clutch is achieved by axially moving the grille towards the motor so that the ends 23 of the leaf-springs ride up over an adjacent part of the motor casing. The grille may comprise three groups of parallel louvres 20 with the louvres of the respective groups arranged at 0, 15 and 30 degrees to the direction of the airflow leaving the vanes 11. The grille, vanes 11, fan casing 1 and inlet cage 5 are all of plastics material.

Abstract: 1,257,970. Digital calculating machines. BELL PUNCH CO. Ltd. 17 Feb., 1970 [17 Feb., 1969], No. 8578/69. -Heading G4A. A digital electric calculating machine as described in Specification 1,242,121 is modified so that the decimal point of the quotient of a division operation is calculated and displayed. The dividend is in the accumulator register 38, the divisor in register 24; division is by repeated subtraction and the quotient is stored in register 38. The decimal point of the quotient is calculated by storing the decimal point of the dividend in counter 56 and adding to it the complement of the decimal point of the divisor from register 24 and the result is displayed on a visual display 14. The visual display.-This display 14 comprises 10 decade-number tubes 16 and ten corresponding decimal point neon bulbs 17 so that the highest significant digit is in the left-hand tube. A decade counter buffer 20 converts a train of pulses from registers 24, 38 or counter 56 into the BCD equivalent which passes, via staticizer 18, to the display. The decimal point is displayed on the appropriate bulb 17, the lefthand bulb being the zero decimal point. The timing is controlled by the timer circuit 12. The arithmetic apparatus.-Two four-stage shift registers 24, 38 controlled by clock pulses perform addition, subtraction, multiplication or division. The decimal counter 56, which is a four-bi-stable, ten state, ripple through counter, holds a digit corresponding to the decimal point -of the dividend stored in the register 38. Numbers are entered and functions chosen through a keyboard (not shown). Operation.-The divisor in register 24 is repeatedly subtracted from the dividend until the answer is negative when one addition is made, and the quotient is stored in register 38. Then the decimal point of the quotient is calculated as described using gates 360 and 580 (not shown). If 'the sum is greater than ten the counter 56 will count through ten and give the correct result. Then the quotient and decimal point are shifted through buffers 20 to their correct display positions.
