Title: Improvements in folder for web-fed printing presses
IPC: B65H45/16
Filed: 1962-11-08
Abstract: 947,475. Paper-folding machines. FRED'K H. LEVY CO. Inc. Nov. 8, 1962 [Feb. 2, 1962], No. 42275/62. Heading B6H. In a mechanism for folding signatures cut from a printed web 13, Fig. 1, and comprising a oylinder 2 with at least one tucking blade 42, Fig. 4, co-operating with jaws 36 on a second cylinder 3, the blade 42 is attached to arms 26 frictionally secured to the shaft 7 of the cylinder 2 which arms carry at their outer end a roller 33 adapted to engage a cam member 35 mounted on the cylinder 3 symmetrically with respec t to the jaws 36, such engagement causing the arms 26 to be moved angularly relatively to the shaft 7, if necessary, to position the blade 42 accurately with respect to the jaws. Such movement of the arms 26 is required, if the cylinder 3 is displaced angularly in small increments relatively to the cylinder 2, as described later, to vary the position of a fold. As shown, the cylinder 2 has two tucking blades 42, each carried by a block 43 secured at each end to an arm 26. The two arms 26 at each end of the cylinder 2 are secured by screws 21<SP>1</SP> Fig. 4, to a split bronze-bushing 21 clamped by a bolt 32 around the cylinder shaft 7 with a running fit. A split hub member 22 having an asbestos brake lining 25 is also secured to the shaft 7 by bolts 23 at least one of which has a tension spring 24. On the hub 22 are two pairs of lugs 29 the distance between each pair of which can be adjusted by a bolt 30. Held between a pair of lugs is a square part of a bolt 27, a round part of which enters a hole in an arm 26. By slackening bolts 27, 30 the hub member 22 may be adjusted as wear of the asbestos lining 25 occurs, so that the lining has the requisite frictional engagement with the shaft 7. As shown, the cylinder 2 has anvils 15 co-operating with knives 14 on a cylinder 1 to cut the webs 13 into sheets, and has the usual impaling pins 16 to take the leading ends of the webs. The cylinder 3 has two sets of jaws 36 corresponding to the two blades 42 on the cylinder 1. A cylinder 4 which takes the folded sheets from the cylinder 3 is identical with cylinder 2 except that it has grippers 46 to engage the leading ends of the sheets instead of pins 16. The tucker blades on the cylinder 4 co-operate with jaws on a cylinder 5 identical with cylinder 3 to impart a further fold. The shaft 7 of the cylinder 2 is driven by helical gears 51, 52, Fig. 3, from the shaft 6 of cylinder 1, and the shafts 8, 9, 10 of the cylinders 3, 4, 5 are driven from the shaft 7 by helical gears 53, 77, 79, 85, 84. The gears 53, 84 are axially adjustable to vary the relative angular positions of cylinders 2, 3 and 4, 5 respectively so as to alter the positions of the fold. During such adjustment, the engagement of the rollers 33 with the cams 35 brings the blades 42 into alignment with their grippers 36. To adjust the gear 53, it is keyed to a sleeve 56 fixed to the shaft 7 and is attached to a bracket 60 movable axially by a hand wheel 76. A similar adjusting arrangement is provided for gear 84.

Title: Thermoplastic linear polyureas and a process for the preparation thereof
IPC: C08L75/02
Filed: 1960-12-16
Abstract: The invention comprises a thermoplastic, linear polyurea having a plurality of repeating units which have the general formula <FORM:0902134/IV(a)/1> wherein R, R1, R2, and R3 are hydrogen or monovalent hydrocarbon radicals and R4 is an unsubstituted or substituted divalent hydrocarbon radical, or an unsubstituted or substituted divalent hydrocarbon radical united by an oxygen atom. The polyurea is obtained by reacting the appropriate piperazine-1,4-dicarbonyl halide with a diamine of the formula NH2-R4-NH2, generally in the presence of an inorganic or organic base and of a diluent, examples of each being listed.  Alkyl, cycloalkyl and aromatic substituents for the piperazine are mentioned.  R4 may be alkylene, cycloalkylene or arylene and suitable substituents are alkoxy, aryloxy, halogen and unsaturated radicals.  In examples polyureas are prepared by reacting piperazine-1,4-dicarbonyl chloride in tetrahydrofuran and in the presence of a base with (1) hexamethylene diamine; (2) decamethylene diamine.  Similarly prepared products from diamines in which the group represented by R4 is ethylene, tri-, hepta- or nonamethylene or (CH2)3O(CH2)3 are also described.ALSO:Piperazine-1,4-dicarbonyl halides of the formula <FORM:0902134/IV (b)/1> wherein R, R1, R2 and R3 are hydrogen or monovalent hydrocarbon radicals and X and Y are halogen atoms are prepared by reacting a piperazine with a carbonyl halide such as carbonyl fluoride, bromide, chloride or iodide in the presence of a base.

Filed: 1973-09-17
Abstract: 1440253 Locks EMHART CORP 17 Sept 1973 [26 Sept 1972] 43470/73 Heading E2A A latch-bolt 20 is retracted by a followeroperated slider 44 sliding in plastics guides 57 against spring 86 when laterally projecting cams 80 are engaged by follower surfaces 92 cut from the hollow handle spindles 88, 89 (called 'rollbacks'), by rotation of handles 96, 97 in either direction. A locking arrangement 100, operable from inside the door, comprises an arm 121 lying a slot 28 in the casing and, when in the upward, locking position shown, also in a slot 91 in the handle spindle 89 to prevent its rotation. This arm is resiliently (124) secured to a strip 102 passing through slot (84) in the slider to a manually operable control knob 111 and biasing spring 118. Retraction of the latch bolt, even when locked thus from the inside, may be achieved by a barrel lock (not shown) in the open end of hollow spindle 89 operating an inner, auxiliary follower sleeve 126 also having cam surfaces acting on the slider cams 80. The slider is connected by a rod 74 and head 76 to a yoke 160 so as to be able to retract it. This yoke is connected to the bolt 20, with lost motion, by pin 156 acting in slot 158. If a picking tool 184 is inserted to retract the bolt when in its fastening position, this lost motion is taken up to cause a ramp depression 168 to displace a follower 178 down into notches 182 to block further retraction of the latch-bolt. An auxiliary bolt 142 is notched to allow passage of this follower when it is held in retracted position by keeper face 138, but prevents it blocking the normal latching operation.

Filed: 1959-12-24
Abstract: 879,843. Grounded aircraft trainers. ACF INDUSTRIES Inc. Dec. 24, 1959, No. 43843/59. Class 4. A grounded aircraft trainer comprises a circuit for simulating to a student the behaviour of a cockpit air heating system of the type using a turbine driven compressor comprising in combination an instrument 6 within the field of vision of a student to represent the speed of the simulated turbine, a reversible motor 2 connected to the instrument to drive the same, and a servo system connected to said motor and including a member 9 under the control of an instructor to energise said motor and bring about rotation thereof in accordance. with the sense and magnitude of motion of the said member. A reversible motor 2 has a shaft 3 to which is connected a synchro 4 to move the pointer of a turbine speed indicator 6, which is positioned in a simulated cockpit within the view of a trainee pilot. Shaft 3 operates a pair of limit switches 7, 8 and the wiper 12 of a potentiometer 16. A second potentiometer 25 is energised from a D.C. source through a pilot-controlled on-off switch 22 and an engine-operated relay 21, the wiper 9 of the potentiometer being adjusted by an instructor by means of control 5. When the trainee pilot closes switch 22 and starts the simulated engine, thereby closing switch 21, a signal of magnitude selected by the instructor is fed from potentiometer 25 to a polarised relay 46 to rock an arm 18, energised at 50, to close a contact 20 and energise a relay coil 24 thereby closing a switch 28 to energise motor 2 from a D.C. source over switch 7 and line 36 through a resistor 31, (which provides dynamic braking of the motor as will be described) the return circuit being through a resistor 32 and open switch 26 to earth. The motor 2 then runs to operate synchro 4 and wiper 12 to a point where the voltage picked off potentiometer 16 balances that picked off potentiometer 25 to reduce the differential voltage across coil 40 to zero so that arm 18 returns to its mid-position and a spring (not shown), returns switch 28 to its open position. The motor is dynamically braked through resistor 31 and motor rotation ceases abruptly. The instructor may set wiper 9 to the maximum speed position so that motor 2 will run until a cam on shaft 3 opens switch 7, thereby disconnecting the D.C. supply over line 36 to the motor and connecting it instead over line 37 to light a lamp 39 to warn the trainee. He should then open switch 22 to de-energise potentiometer 14 whereby the voltage derived from potentiometer 10 only is applied to relay 46 causing arm 18 to rock off contact 20 on to contact 19 to energise coil 23 and close switch 26 to connect motor 2 over resistor 40, line 38 and switch 8 to a D.C. source. This runs motor 2 in the opposite direction, at a slower speed due to resistor 40, to simulate the turbine slowing down, until a cam on shaft 3 opens switch 8.
