Filed: 1969-12-12
Abstract: 1293770 Linkwork P R PHATAK 12 Dec 1969 60867/69 Heading F2K A mechanism for converting a rotary motion into a concentric and periodically varying or intermittent rotary motion comprises a four-bar linkage a, b, c, d which can rotate about an axis M, about which link a is pivotally mounted, and a cam Y which is engaged by a follower N on link c. A driving arm g is mounted for rotation about an axis M and is formed with a longitudinal slot which engages a pin P on the link b. Similarly, a driven arm h has a longitudinal slot which engages a pin R on link d. The camfollower N may be maintained in contact with the cam by centrifugal force. Alternatively, the cam-follower N may be resiliently urged towards the cam or may be located in a groove in the cam. In a modification, the axis of rotation M coincides with the axis of the pivot connecting links a and b. In the arrangement shown in Fig. 3, two sets of diametrically opposite symmetrical four-bar linkages are rigidly connected together and two cam-followers N engage a symmetrical cam Y. In a further modification, shown in Fig. 4, four sets of four-bar linkages are used. Additional periodic variations of the output may be obtained by gearing the cam means to the input or output means or to some external mechanism.

Abstract: 1329472 Making honeycomb panels and heat exchangers SOC NOUVELLE RADIAL 23 Dec 1970 [23 Dec 1969] 61025/70 Heading B3A [Also in Division F4] A heat exchanger unit, consisting of an expanded metal body 1 through which a tube 21 passes, is made by connecting together a number of flat strips to make a stack, drilling a hole through the stack, expanding the stack to cellular form (Fig. 1) so that the drilled hole now provides a series of aligned holes, making radial cuts around the holes, and forcing a tube into the holes. The flat strips are connected along selected transverse bands, and then secured together. The drilled hole has a diameter smaller than that of the tube and the aligned holes are enlarged (Fig. 4) by a tool (Fig. 5) which has radial cutting edges and is drawn through the holes. The heat exchange unit may be combined with other units in series or parallel (Fig. 1) or may be used as a space-heating radiator, a heat engine radiator, or in a refrigerator. The unit may be immersed in a metallizing or graphitizing bath during its assembly to improve its efficiency. The bath may contain a drying or non-drying linseed oil, stand oil, a binder such as a synthetic phenol resin, a glycerophthalic epikote resin, a silicone, a chlorinated or isomerized rubber, or a powder such as zinc, aluminium, copper or graphite. The parts of the heat exchanger itself may be formed from copper or aluminium or an alloy based on one of these metals.
Patent GB-719137-A (GB)
Abstract: 719,137. Cash registers. NATIONAL CASH REGISTER CO. July 14, 1952 [Aug. 10, 1951], No. 18846/51. Class 106 (1) In a cash register or similar accounting machine, wherein a record strip is severed into an issuing portion and a stub retained by the machine, a slidable member operating the severing mechanism is actuated by a cam driven by a dog which engages a lost-motion slot in the cam permitting rapid return of the slide under spring action. Strip feeding and impression mechanism.-The strip 70 is fed by rollers 54 and 55 over the type wheels 16 and through a guide 71 to the severing knives, beyond which lies an issuing outlet 135. During initial counterclockwise rotation of a main shaft 12, a rise 140 of a cam 18 therein pivots a bel'-crank 20 clockwise, and an arm 40 bearing a printing hammer 43 is rocked by the bell-crank to impress the strip upon the type wheels 16. Immediately thereafter, the toothed portion of a partially-toothed wheel 69 on the main shaft commences to drive a pinion 68 fast with the feed roller 55, so feeding the strip with the first print thereon towards the outlet 135. As the strip moves forward, the hammer 43 is again operated by means of a second rise 141 of the cam 18, this second print becoming located between two stationary cutting blades 80 when forward feed of the strip ceases. Severing mechanism; storing receipts.-The stationary blades 80 converge upwardly and to. wards the left of the machine. A cutting knife 90 with two cutting edges is inclined upwardly towards the left (see Fig. 5) and is mounted on a vertical spring-actuated slide 84 having a follower roll 100 engaging a cam 101 loose on a shaft 13 and adapted to be driven from the shaft through a dog 104 engaging a lost-motion slot 105 therein. Towards the end of the machine cycle, the lostmotion having been taken-up, the cam 101 depresses the slide 84 causing the knife 90, in conjunction with the stationary blades 80, to sever the strip 70 in two places straddling the second print so that this portion of the strip passes down a chute 130 and into a locked drawer 124. The leading portion of the strip bearing the first print can then be withdrawn from the out'et 135. The lost-motion drive to the cam 101 allows a spring 96 to return the slide 84 sharply, and a pin 132 thereon rocks the chute 130 about a pivot 131 to agitate it and ensure discharge of the severed portion of the strip. Suppression of printing. The printing hammer arm 40 is actuated by a pin-and-slot connected intermediate arm 35 having a pin 34 extending into a slot in the end of a further arm 26, Fig. 2, the slot normally also engaging a pin 25 on the bell-crank 20 so that the bell-crank is effective to actuate the hammer arm 40. Movement of a lever 33 to the non-print position slides the arm 26 clear of the pin 25 in the bell-crank which then rocks idly without actuating the hammer arm. The lever 33 is also adapted to retract the pressure roll 54 for the feed roller 55, and a pressure roll 64 adjacent the printing wheels, so that the strip is not fed when impressions are not required.
