Title: Motion transmitting device utilizing the johnsen-rahbek effect

Filed: 1971-11-16
Abstract: 1313820 Electrostatic mechanisms NATIONAL CASH REGISTER CO 16 Nov 1971 [23 Nov 1970] 53083/71 Heading H1P A motion transmitting device 10 utilizing the Johnson Rahbeck effect comprises drums A, B, C conventionally rotatable on axial shafts and coated with semi-conductor 1 and on the peripheries, which are rotated at constant velocities but differing peripheral speeds. A conducting band 20 surrounds portions of the peripheries of the drums and is tensioned by spring 22 at one end while the other is connected to operate, e.g. a print hammer lever 24. Slip rings 26, 28, 30 enable the drums to be energized from electronic circuitry 32; the band being normally grounded and slipping. A pulse of potential (Fig. 2, not shown) on drum A attracts the band to impart motion and displace the band from 36 to 40 (Fig. 3) and after a fixed time a pulse on drum B attracts the band to add to the existing velocity ; drum B being simultaneously de-energized, and the band is displaced from 40 to 44. Then after a fixed time a pulse on drum C replaces that on drum B and similarly adds velocity, and the band is displaced from 44 to 46, when it is at its terminal velocity, and drum C is de-energized. The device thus produces a smooth acceleration, and can be used in reverse sense for deceleration. Plural bands may be utilized on the same drums, and for selective acceleration the band ends are separately attached to tensioning spring returned to an insulant support, and a further electronic control circuit responsive to circuit 32 initially selects the band to be energized (Fig. 4, not shown).

Title: Improvements in or relating to circulating liquid pumps incorporating mixer valves

Filed: 1970-11-19
Abstract: 1300460 Central heating systems K SCHICHL 19 Nov 1970 [20 Nov 1969 25 March 1970] 54964/70 Heading F4U [Also in Divisions Fl and F2] In a circulating pump, e.g. for central heating systems, having the pump impeller 6, Fig. 2, and a rotary mixer valve 7 arranged coaxially in the same casing, the rotary valve is adjusted into a desired angular setting by mechanical or hydrodynamic coupling with the impeller drive. The impeller continuously delivers through connection HV to the heating system and is supplied, depending on the setting of the valve 7, either through connection (KV), Fig. 1 (not shown), with hot water from the boiler, or through connection (HR) with return water from the heating system, the connection KR being connected to the boiler return. The valve is held in the desired setting'by a spring latch 20 engaging one of four depressions (24), Fig. 3 (not shown), in the periphery of the valve. Actuation of an electromagnetic control system, incorporating an eccentric plate 17 and linkages 16, 19, disengages latch 20 and moves a shaft 13 axially to temporarily engage a rotating cone 10 on impeller drive shaft 3, with the valve to thereby angularly adjust the latter to a new setting. In another embodiment, Figs. 4 and 5, an impeller 104 is continuously supplied through connection 1 and delivers to a helical channel 107 which discharges the water through a longitudinal slot (not shown) in the cylindrical wall 105 of a surrounding rotary mixer valve having two dividing vanes 106. The flow from the slot is directed, as shown in Fig. 5, tangentially of wall 105 so that when electromagneticactuated latching means 112 is temporary released from the respective depression 115, the valve is hydrodynamically rotated clockwise through 90 degrees to a new setting. Thus the connection 1 can be communicated with either the connection IV as shown, or with the connection II. One of the connections may be permanently closed so that there are only three effective connections.

Abstract: 1280549 Packaging machines EMHART CORP 12 Nov 1969 [13 Dec 1968] 55299/69 Heading B8C In a packaging machine, a line of towelpaper rolls 14 is fed along a conveyer 12 and on to a table 40, and a detector 76 is operative, when the table is fully loaded, to cause the table 40 to be retracted from the conveyer 12 and to operate a clamp 58 which engages the leading roll on the conveyer 12 to halt the feed of the rolls. The rolls on the conveyer 12 are subject to a cumulative pressure which compresses them longitudinally of the line, and the rolls on the table relax on retraction thereof. The table 40 comprises two sets of parallel rails 42 which receive two rows of rolls from the conveyer 12, is supported by rollers 50 running on guide rods 48, and is reciprocated along the rods 48 by means of a crank 54 pivoted by a cylinder 52. The last roll feed to the table 40 is held in position by a clamp 62. On complete retraction, the table 40 engages a switch 80 to actuate a fluid motor 74 which raises two lift tables 68 to push the rolls into a collector 24. When the collector is full, a pusher (32, Fig. 1) operates to push the stack of rolls into a container.

Patent GB-575100-A (GB)
Abstract: 575,100. Calculating machines. AKTIEBOLAGET FACIT. Oct. 28, 1943, No. 17835. Convention date, Nov. 30, 1942. Addition to 551,311. [Class 106 (i)] The parent Specification relates to a calculating-machine having an actuator rotatable in two directions and is characterised by a chief control lever (201) manually settable to three positions, two for multiplication and one for division. The calculating-machine described in the parent Specification is characterised in that the revolutions counter actuator is automatically disabled when the chief control lever 201 (not shown) is set for division and the addition or subtraction keys are operated. As described in the parent Specification, with the chief control lever set for division, the gear 220 secured to the shaft 218 and used for actuating the revolutions counter (not shown) is moved to extreme left position to couple up with a gear 223. In known manner, the dividend is entered into the pin-wheel rotor 4 which is then tabulated to extreme left position. Depression of the addition key 203 rocks the lever 344 clockwise to pull a bar 554 downwards. A nose 557 on the bar 554 rocks a latch 558 clockwise against spring pressure to declutch the gear 561 carrying the latch 558 from a gear 564 and to engage an arm 558b of the latch with a part 566 of the frame.. At the same time, an extension 354 of the lever 344 engages and depresses the motor key 1 which rocks a contact lever 331, Fig. 4, clockwise to close contacts 334 and supply current to the motor. The lever 344 also rocks a pawl 569, embracing a fixed pin 351 clockwise and the lever 331 rocks an arm 505 counterclockwise in Fig. 4, to engage the top of the arm 569 to hold the key 203 depressed until the addition cycle has been completed and the lever 331 is restored in the manner described in the parent Specification, the rotor being cleared in known manner. Since the gear 561 is free of gear 564 and is held stationary, no drive takes place via gear 223 to the revolutions-counter actuator 220. When the key 203 returns, the nose 557 of the bar 554 releases the latch 558 which is now freed from the frame 566 and clutches the gears 561, 564 together. The divisor is then entered into the rotor and the division key 2 depressed when, since the bar 564 is not pulled down, full automatic division is effected, a drive being effected to the revolutions counter via gears 564, 561, 223, 221. If the multiplication key 1 is depressed, the bar 564 is not affected and the revolutions counter receives entries. With the chief control lever 201 set for multiplication, the gear 220 is coupled to the gear 222 and the revolutions counter receives an entry at every revolution of the rotor no matter what key is depressed. In a modification, a particular pre-setting key, coupled to the bar 564, is provided which, when depressed, enters the dividend into the results register without any actuation of the revolutions counter. Specification 413,205 is referred to.

Slide 4 has a bore 18 into which a reamer 42 may be inserted and adjusted. A pad 25 carries a point 26 or drill, and the pad is urged downwardly by two springs 27, Fig. 6, located in sleeves 34. A clamping plate 28 is secured by bolts 29 to a ring 32, which is screwed into an adjusting nut 36, so that plate 28 can clamp slide 4. Sleeves 34 are prevented from being pushed out of body 2 by discs 40, 43, Figs. 4, 5, which co-operate with flats 42, 44, Fig. 6. Disc 43 is rotatable about its axis, and has a torsion spring 45. In operation, a centring hole is first drilled by drill 35, pad 25 is prevented from retracting by disc 43, which is frictionally engaged with flat 44. When the drill breaks through, disc 43 moves away from flat 44, due to springs 27, and is rotated by by spring 45.
