Title: An apparatus and method for enclosing a letter in an envelope
IPC: B43M5/04
Filed: 1962-10-23
Abstract: 1,019,585. Enclosing letter sheets in envelopes. J. V. WORTHINGTON (EN MAIL CORPORATION). Oct. 23, 1962, No. 39987/62. Heading B8C. A method of enclosing a letter sheet in an envelope consists of folding the letter sheet, laying an envelope blank on the sheet and folding and securing it about the letter. The sheet may be folded about one or more enclosures and an address card may be placed on it prior to wrapping in the envelope if the latter is windowed. Letter sheets 7, in a magazine 60 having belts 61 at the base to urge the sheets forward, are individually lifted by suction heads 75 and fed forward by rollers 93, 94, past a drum 96 with ribs 97 to form crease-lines. Each sheet abuts a stop 109a which causes it to fold along one of the crease-lines (Fig. 1). Any desired enclosures are, at this stage, delivered by a conveyer comprising reciprocating dogs 110 operating through a support 52, into the, letter sheet. These enclosures are fed from magazines 3, 4 to the conveyer by a suction picker (Fig. 5, not shown) and a belt 51. The sheet with its inserts enters between plates 293 and 275 of a folding device (Figs. 7 and 11, not shown), and are then as shown in Fig. 20. The device rotates 180 degrees to fold the sheet about the inserts to form the unit shown in Fig. 21, and present a second pair of plates 293 and 276 to receive the next sheet. A conveyer dog 298 pushes the unit to beneath a presser 301 and it 'then moves to a position where, if desired, an address card 12 is now delivered on to it from a storage magazine 11 by a suction picker and a belt 51a.  The envelope blanks 14, into which the letter sheets &c. are to be enclosed are cut from a roll and have adhesive applied. If desired windows are formed in them and they are positioned faceupwards above the unit in the folding station 13 (Fig. 1). The unit 10 is fed by the. conveyer on to a two-part platform 156 (Fig. 25) which rises to carry it against the envelope blank resting on supports 153, and then up to a plate 173, which produces partial folding as in Fig. 26. Part 155 of the platform descends enabling a tucker 188 to operate on a side flap, the part 163 of the platform commences to descend and further sliding tuckers, Fig. 29 (not shown) fold in the opposed end flaps. Finally a pusher 205 ejects the envelope over a fixed folder, Fig. 18 (not shown) and between a belt and roller with consequent folding and securing of the top flap.

Leaf-spring 34 is adjustable along the handle 10 by screw clamp 38 and has two steps 40 and 42 for different sized containers. Bracket 25 is pivotally connected to plate 12 by balls 26 on arms 24 having a snap engagement with sockets 28. The wax on plate 12 flows through holes 70 to impregnate pad 72 which is secured to the plate by the engagement of its beaded or rolled edges in grooves 74. In an alternative method of attachment of pad 74 (Fig. 4, not shown), resilient wire holders are pivotally mounted on plate 12.

Filed: 1970-08-25
Abstract: 1307275 Automatic level control SOC ANON DES ATELIERS HOUGET DUESBERG BOSSON 25 Aug 1970 [25 Aug 1969] 40825/70 Heading G3R [Also in Division D1] A system for controlling the level of textile fibre in a chute supplying a hopper, comprises an electro-acoustic detector affected by the height of fibre in the chute so as to control an inclined elevator supplying the chute, there being an adjustable time delay unit to cause the level to fluctuate between two different levels. In Fig.1, textile material supplied to a feed box 1 is transported by a slow speed conveyer 2 towards a spiked elevator 3. A comb 4 removes and opens surplus material from the elevator and the remainder passes on to be transferred by a high speed spiked cylinder 5 to a hopper 6 feeding a chute 7. Cylinder 5 also produces a slight air-pressure on chute 7. Delivery wheels 13, 14 supply material from chute 7 to a conveyer 15 which supplies it to a following machine e.g. a carding engine. Rise in level of the fibres in the chute blocks the transmission of energy between an ultrasonic electro-acoustic transmitter and receiver on opposite sides of the chute at 18 so that a relay is operated to stop an electric motor driving elevator 3. Then, by virtue of a time delay associated with the relay, elevator 3 is re-started a predetermined time after the level falls. The time delay is adjusted to suit the rate of feed and obtain a desired difference between the levels at which the elevator is stopped and started. One side 12 of chute 7 is transparent to allow inspection and is adjustable in position to vary the volume with one side of hopper 6 pivotting at 10.

Isopropenoxy-silicon compounds are prepared by reacting chloro-silicon compounds with metallic sodium and acetone. The chloro-silicon compounds preferably contain, in addition to the Si-Cl bonds, monovalent or polyvalent hydrocarbon radicals bonded to Si, which radicals may be interrupted by oxygen atoms in ether linkages or may contain other substituents inert to the reaction. Preferred chloro-silicon compounds are silanes of the formula R n SiCl 4-n , in which R is a monovalent radical as defined above, and n is 0, 1. 2 or 3; chlorosiloxanes containing units R x SiCl y O 4-x-y/2  in which x is 0, 1, 2 or 3, y is 0, 1, 2, 3 and the sum of x and y is 1, 2 or 3, there being at least one chlorine atom per molecule; and silcarbanes of the formula Cl 3-m SiR m R<SP>1</SP>SiR x Cl 3-x , in which R<SP>1</SP> is is a divalent radical as defined above, x is 0, 1, 2 or 3 and m is 0, 1 or 2. R is preferably the methyl radical. The sodium is used in the form of a dispersion in a liquid inert medium, e.g. a hydrocarbon or an ether, and the reaction may be carried out in a similar solvent, and comprises introducing equivalent amounts of sodium and acetone, each diluted in the inert solvent, separately but simultaneously into the chlorosilane, also diluted by the solvent.

Title: Trap means for grasping a probe carried by a helicopter
IPC: B64F1/12
Filed: 1969-08-21
Abstract: 1275442 Trap device for an aircraft anchoring probe CANADA MINISTER OF NATIONAL DEFENCE 21 Aug 1969 [4 Sept 1968] 41729/69 Heading B7G [Also in Division E2] A trap device on a landing station or platform is designed to grasp a probe mounted on the underside of an aircraft capable of hovering, once the aircraft has been drawn down by a winch below the trap, by means of a cable secured by the probe, and thus to secure the aircraft against lateral motion. The trap, seen in perspective in Fig. 3, comprises a housing 31 formed by four members 31A-31D bolted together to form a rectangle, and two parallel beams 33A and 33B which may be moved towards one another across the housing. An hydraulic jack 71 controls the motion of the beam 33B by moving a chain 79 (Fig. 6) which turns a sprocket 81, which being bolted on the same shaft as sprocket 95 moves a chain 93 which bears a crosshead member 99, connected by cables 101, 103, 105 and 109 to the beam 33B. A similar assembly mounted on the opposite side of the housing controls the movement of beam 33A. A cable 5 from a winch (15, Fig. 1, not shown) below the platform is secured by the probe on the aircraft, and is then drawn in down until the probe lies between the beams 33A and 33B, whereupon the means for operating the beams is actuated, causing them to move towards one another. If the probe is not vertically above aperture 45 one beam will strike the probe and be arrested until the other beam meets the probe, when spring-loaded catches 165 on beam 33A will engage abutments 167 on beam 33B, locking the beams together and trapping between them shuttles 41, which are free to move in the same direction as the beams. The shuttles are then held in position by a means to be described, so that the aircraft is held against lateral motion perpendicular to the beams, and spring-loaded plungers 39 mounted on each beam prevent motion of the probe along the beams. The shuttles 41 are connected to chains 205 wound round sprockets 207 near the respective corners of the housing, and these sprockets are provided with releasable holding devices 215, shown in detail in Fig. 9. Each device comprises a flange 271 which rotates with the sprocket and is provided on its upper surface with a set of teeth 273. In an annular cavity above this is an annular member 289 having on its lower surface a complementary set of teeth 291. Four spring- loaded plungers 293 serve both to prevent rotation of member 289 and to force it downwardly so that the two sets of teeth mesh, thus locking the sprocket 207. The lock may be released by forcing hydraulic fluid through the pipe 301 into the space between flange 271 and member 289. Hydraulically operated means is provided (Figs. 7, 8, not shown) for releasing the catches 165 and this is associated with switches for indicating whether the beams are locked or released.
