Abstract: 1,063,570. Friction clutch-brake combinations. MARINE ENGINEERING CO. (STOCKPORT) Ltd. Dec. 9, 1964 [Dec. 14, 1963], No. 49486/63. Headings F2C, F2E and F2L. A friction clutch-brake apparatus comprises a flywheel 16 on a shaft 10 driven by motor M, a ferrous disc 15 on a driven shaft 12 and a sleeve 20 slidably mounted by studs 22 in a housing 11, a flange 21 of sleeve 20 and the flywheel 16 carrying permanent magnets 25, 18 and friction linings 24, 19. As shown, the magnet 18 holds disc 15 against lining 19 to drive shaft 12 and pulley 13 but on movement of sleeve 20 by lever 26 to a position close to disc 15 as defined by a stop 29, the magnet 25 attracts disc 15 away from the flywheel and so brakes it and shaft 12, the lining 24 being thinner than lining 19 and the magnets being of equal strength. To reconnect drive the sleeve 20 is moved away from the flywheel and since movement of shaft 12 and its bearing block 30 is limited by housing wall 33, the flange 21 leaves disc 15 which is then attracted back to flywheel 16. In a further embodiment, Figs. 2, 3 (not shown), the disc on the driven shaft carries the friction linings and is moved by means of a peg on its bearing sleeve being moved in a helical slot in the fixed housing by a linkage controlled by a pedal; a permanent magnet on the flywheel holds the disc in the clutch position and a spring acting on the peg holds it in braked position. Threaded studs which prevent a braking member from rotating have nuts whereby the member can be adjusted axially.

Abstract: 1485168 Flying saws SCHUMAG SCHUMACHER METALLWERKE GmbH 25 Nov 1974 [4 April 1974] 50982/74 Heading B5L [Also in Division B3] A flying shear or saw comprises a tool slide, a drive arranged to impart to the slide a speed which, unless reduced by braking, exceeds the speed of the material to be cut, a member kept moving in the same direction and at the same speed as the material and an overrunning clutch between the slide and the member so as to prevent the slide from exceeding the speed of the material, while permitting the slide to lag behind the member. As shown, Fig. 1, a slide 2 is attached by a rope 19 to both sides of a piston 18 in a double-acting pneumatic cylinder 17. A chain 14, constantly driven in direction 52 at the speed of material 1 to be cut via gears 11, 12 and shaft 13, passes round a chain wheel 16 mounted on an overrunning clutch 25, Fig. 4, on the slide 2. The wheel 16 can rotate freely in the direction of arrow 54, on rotation in the opposite direction, the clutch engages. The shaft 13 may be the main shaft of the machine producing the material 1 and may also drive the parting tools. In use, compressed air is supplied at 28 to drive the slide, carrying a shear 23 or saw 22, along tracks 4 in the same direction as, but faster than, the material 1 and thus the chain 14. At the moment when the wheel 16 would reverse, the clutch 25 engages and holds the slide at the speed of the chain 14 until the piston stroke is reversed. The required stroke length of the slide is less for a shear than for a saw cut. The piston stroke is reversed when a contact registers the completion of a cut.

Abstract: 1528369 Signalling over power lines AMERICAN SCIENCE & ENG Inc 12 Dec 1975 [20 Feb 1975] 51056/75 Heading H4R In an arrangement for signalling over power lines a unidirectional voltage is derived from the power line by rectifiers 501 and 502, and drive signals applied in antiphase to transistors 504 and 505 at a carrier frequency modulated by digital data to be transmitted. Switching on of transistor 504 causes capacitor 510 to charge and slowly switch on transistors 511 and 512 so that capacitor 528 is able to charge from the supply line 526, charging current flowing through resistor 527 turning on triac 529. When the carrier signal turns transistor 504 off transistors 511 and 512 are turned off as capacitor 510 discharges. Turning on of transistor 505 by the carrier signal on terminal 136' transistor 515 is turned on to allow capacitor 519 to charge up turning transistor 520 on slowly to connect line 525 to the power supply line 24<SP>1</SP> capacitor 528 is therefore discharged and the discharge current in resistor 527 again makes triac 529 conduct. Switching off of transistor 505 by the carrier signal allows transistor 520 to be turned off slowly as capacitor 519 discharges. Diodes 514 and 522 are provided to clip reverse voltage spikes produced by the inductance of the power line and its transformer when the transistors 512 or 520 are turned off. The voltage transitions of line 525 are coupled to the power supply line via capacitor 109.

[Also in Division G2] An image 26 is generated in an image plane by first constructing an object 25 having controlled phase retarding areas and then illuminating the object by electromagnetic waves 24 which are selectively retarded by the object and produce in the image plane resultant interference in the pattern of the image 26, there being no diffraction into other than a predetermined order. The object 25 is a kinoform and is formed by calculating on a computer the phase distribution required to produce a desired 3-D image assuming a constant amplitude. This follows the steps of (a) specifying the desired amplitude T R [a,b], (b) multiplying a random phase factor exp. [i#(a,b)] on the image amplitude whereby T R =T - TR exp. [i#], (c) computing the backward propagation of the complex wave amplitude T from the image plane by means of a Fresnel transformation T*F = | h | exp.

[i#(x,y)]. The phase distributing object is preferably transmissive and of varying thickness. The phase factors preferably approximate a collection of discrete point apertures which may be 3-D with each aperture assigned a value of between 0 and 1, where 0 implies no light transmittance and 1 implies an open aperture and the values between represent relative transmittance. The illumination may be coherent light, ultrasonic waves or microwaves. Each area of object 25 contains the total information necessary to reconstruct the imaage.
