At the pressing station a punch 208 moves down forcing the blank into a die, both punch and die retract to release the carton. A pre-folding device 210 having fixed and retractable pegs determines the order in which the walls and flanges are folded during formation of the carton. Subsequently, the formed cartons are ejected and moved into the bottom of a column stacking unit.

Title: Process for the preparation of methyl magnesium compounds from dimethyl sulphate
IPC: C07F3/02
Filed: 1957-11-28
Abstract: Dimethyl sulphate is reacted under substantially anhydrous conditions and at low temperature with magnesium in a solvent comprising tetrahydrofuran, tetrahydropyran or an alkyl derivative thereof, or a polyethylene glycol ether of formula R.(OCH2.CH2)vOR1 wherein R and R1 represent the same or different alkyl groups and n is an integer. Preferably R-R1 each contain not more than 4 carbon atoms and n is 2 or 3, e.g. diethylene glycol diethyl and dibutyl ethers.  The reaction is carried out under a nitrogen atmosphere and it may be activated by an iodine crystal.  Insoluble magnesium methyl sulphate is precipitated, usually not in large quantities. It may be eliminated by filtration or decantation.  The product solution may be used in Grignard reactions without isolating the products.  In the examples magnesium and dimethyl sulphate are reacted in (1) tetrahydrofuran, (2) tetrahydropyran and (3) diethylene glycol diethyl ether.

Title: Device for turning bed of granular-like material
Inventor: THOMPSON DOUGLAS LYALL
IPC: C12C1/15
Filed: 1965-08-31
Abstract: A device for turning a bed of granular material comprises a frame, an apron (14) with a scoop edge (18) and a spilling edge, and means for cycling the apron between a raised and a lowered position.  The scoop edge is mounted on arms (48) which slide in housings (50) on the underside of the apron and during raising of the apron the edge is extended to pick up the material which slides across the apron to be deposited on the other side of the device.  During lowering of the apron the edge (18) is retracted so that it will not contact and damage the material.  A panel (80) oscillates in conjunction with the apron to compact the material after it has been deposited from the apron.  A magnetic coupling means (70) controls the relative movements between the apron and the scoop edge.

Title: Improvements in or relating to electric motor control systems
IPC: B60L7/02
Filed: 1959-11-03
Abstract: 882,625. Control of several D.C. motors. BROOKHIRST IGRANIC Ltd. Nov. 3, 1959 [Nov. 3, 1958], No. 37249/59. Class 38 (3). A control system for a drive having at least three series-wound reversible motors includes dynamic braking means rendered effective when the motors are disconnected from the power supply, the braking means comprising means for energizing the series field winding of each motor by the current generated by one of the other motors in the same direction as the immediately preceding power energization of each such field winding regardless of whether the motors were operated in the forward or reverse direction. As shown, motors 1, 2 and 3 are connected in parallel across positive and negative supply lines L1, L2, the field F1 of motor 1 and the armatures A2, A3 of motors 2 and 3 each being connected in reversing bridge networks, the arrangement being such that with the motors disconnected from the supply armature A2 is in series with dynamic braking resistors DBR1, DBR2 and field F1, armature A1 is in series with resistors DBR3, DBR4, DBR5 and fields F2, F3, and armature A3 is in series with resistor DBR6. In operation, with the operating coil of a relay UV energized, contacts UV1 close to energize a relay DB and contacts UV2 close a point in the energizing circuit of contactors M, F and R. Relay DB opens contacts DB1 to DB6 to interrupt the dynamic braking loop circuits, closes contacts DB7 to energize contactor M and closes contacts DB8 to close a point in the energizing circuit of contactors F and R. Contactor M closes contacts M1, M2 and M3 in the power circuits of motors 1, 2 and 3. Closure of switch SW energizes either contactor F or contactor R which close contacts 1F1 to 3F2 or 1R1 to 3R2 in the reversing bridge networks so that the motors run in the forward or reverse directions as required. If voltage failure occurs, relay UV responds and contacts UV1 and UV2 open to de-energize contactors M, F and DB, thereby opening the reversing bridge contacts and the contacts M1, M2, M3 to disconnect power from the motors, and closing contacts DB1 to DB6 to establish the three dynamic braking loop circuits, the braking effect of one of the motors being reflected in the field excitations of the other motors to maintain braking on all three motors. In a modification (Fig. 2, not shown), armature A1 is connected in series with field F3 and resistors DBR3 and DBR4, and armature A3 is in series with resistor DBR5 and field F2, a rectifier bridge being employed to maintain unidirectional excitation of field F2 with reversal of counter EMF of motor 3. Spring- closed contacts may replace the rectifier bridge (Fig. 3, not shown), or the reversing contacts of motor 3 may be used for connecting armature A3 to field F2 for dynamic braking (Fig. 4, not shown).

[Class 39 (iii)] An electrically heated blanket, trellis, netting or panel has a heating element composed of two distinct constituent parts combined to form a linear conductor, one of the said parts being a heater of low melting point that fuses before a dangerous temperature is reached. The heater may be a wire of low melting point wound on-a flexible or rigid insulating support. Alternatively, the wire of low melting point may be disposed alongside, twisted with or wound on a fine wire of high melting point. The heating element may also be a conductively coated thread of insulating material. The blanket, trellis, netting or panel may comprise one or more of the above elements in a . sheath of material, fireproof or otherwise such as india-rubber or fabrics impregnated with india-rubber or not. Alternatively the heating element may be secured to a sheet support and, if desired, covered with a coating of insulating varnish or a fabric or both. The heating elements may be plaited, woven or knitted into a network. The Specification as open to inspection under Sect. 91 comprises also a narrow linear deposit of any configuration upon a non-conductive sheet of spun glass, india-rubber or other suitable material. This subject-matter does not appear in the Specification as accepted.

Abstract: 1369877 Take-up motions JOHNSON & JOHNSON 21 Sept 1971 37374/72 Divided out of 1369876 Headings D1E and D1K A loom for weaving elastic ribbons with non-elastic portions has a ratchet operated take-up motion which takes up the cloth at two different rates, one relatively high rate so that the cloth may subsequently contract to form the elastic portions and one relatively low rate to form crammed weft portions wherein the cloth cannot contract and consequently cannot stretch and thus forms a non-elastic portion. The take-up roll is normally driven by a ratchet wheel 36 having a slotted arm 32 oscillating the wheel 36 by way of pin 53 sliding in the slot, near the outer end of the slot, the pin 53 being moved by the oscillation of a rod 29 driven by the picking motion. When the high rate is desired a dobby mechanism causes the pins movement to be effective near the inner end of the slot to increase the stroke of the arm 32.

The arm 31 has a finger 30 which is engaged by a cam surface 32 on the machine frame so that, as the slide 11 is moved away from the work, the arm 31 is lifted and gives a partial rotation to the shaft 27 sufficient to move the grinding-wheel transversely an amount to compensate for its reduction of diameter due to wear and trimming. The grinding-wheel is trimmed, so that the periphery is a semi-circle in axial section, after operation on each work-piece, by a diamond &c. carried by an offset part of a holder 45, which is oscillated about an axis 47 by a rod 53 operated by an offset pin 52 on a disc 51 driven, through gearing, from a Pelton wheel or other motor 50, the operation of which is controlled by a valve. The holder 45 oscillates in an arm 43 pivoted at 41 on a frame 42 on the slide 11, and the arm is moved, to carry the diamond against the wheel 66 when this is retracted from the work, by a lever 40 operated, through a rod 39, by a bell-crank lever pivoted at 37 on the slids 11, the arm 35 of the lever engaging a pin 34 whereby the lever is rocked.
