Title: Improvements in or relating to packaging material
Inventor: LANE WILLIAM CHARLES
IPC: B31F1/28
Filed: 1960-04-13
Abstract: 939,106. Corrugating paper; laminates and laminating. REED CORRUGATED CASES Ltd. March 30, 1961 [April 13, 1960], No. 13252/60. Classes 42 (2), 96 and 140. [Also in Group XVII] A corrugated packaging material comprises a backing sheet 1, e.g. kraft paper, adhesively secured to the crests of arcuate flutes 3 of a corrugated sheet 2 of paper formed with alternate arcuate flutes and wider, oppositely facing, flat crested flutes 4. The sheets 1, 2 are of uniform thickness and the side walls of the flutes 3, 4 are convergent towards the crests. Strips of reinforcing material, e.g. plastic film, regenerated cellulose, metal foil, may be secured to the material either transversely across the flat crests externally, or between the backing and corrugated sheets, either transversely of the flutes or along the channels formed by the flat flutes. Either the backing or corrugated sheets, or both, may be formed as a laminate incorporating a sheet of reinforcing material, e.g. a plastic film material or metal foil. The preferred width ratio between the flat flutes and the arcuate flute is 1.5 to 1, and the flat flute channels may be filled with a cushioning material, e.g. granulated cork. Two sheets of material, with differently sized flat flutes, if desired, may be joined to form a multi-wall material, Fig. 4, by securing together with adhesive the flat faces of their respective flat crested flutes. The machines (Figs. 7, 8 and 9, not shown), for forming the corrugated material and at the same time inserting or affixing the reinforcing strips, and for filling the flat flute channels with adhesive followed by cork granules are of conventional type, their corrugating rolls being shaped to the required form. In forming the laminated product, the plastic film, e.g. polyethylene, and paper sheet may be fed separately to the corrugators and fluted together.

Abstract: 749,313. Thermal switches; switches held set and freed mechanically. HOTPOINT ELECTRIC APPLIANCE CO., Ltd. May 6, 1954 [May 13,1953], No. 13306/53. Class 38(5) A switch for use in an iron, kettle, &c., comprises a pair of contact members, a thermal element acting on a displaceable element which controls the movable contact member, said displaceable element being spring-loaded in a direction transverse to that in which it is moved by the thermal element and transverse to the direction of movement of the part of the movable contact member engaged by the displaceable element. As shown, the latter is a resilient strip 22 carried by the free end of a bimetal strip 21 and having inclined faces 24 and 26 and an intermediate face 25. When the bimetal is cold, the face 25 rests on a roller 34, carried by a channel-shaped part 32 of the movable contact member 18 which is flexible about a part 30 and is biased towards fixed contact member 17, so as to stress the member 22. When the latter moves to the left on heating of the bimetal, the face 24 eventually meets the roller 34 and the contact member 18 is forced to the right to open the contacts by the cam action of face 24 and roller 34 due to the resilience of member 22. As the bimetal recools, the member 22 draws member 18 further to the right and the contacts need to be reclosed by a push-button 38. This acts on a spring 41 having an end 43 engageable with the face 26 of member 22 which can thereby be lifted to release member 18 and thus place parts 25, 34 in re-engagement. The contact members and the bimetal are carried by a stack secured to the casing 13 by a bolt 45 and nut 47 which is engaged by an earthing tag 48 connected to earthing contacts 51 adapted to engage earthing contacts on a socket connector.

Title: Improvements in or relating to boring or drilling tools
IPC: E21B10/44
Filed: 1937-05-10
Abstract: 494,976. Percussive drills. PHILLIPS, N., and CLOW, A. C. May 10, 1937, No. 13316. [Class 124] [Also in Group XXII] Boring or drilling tools are formed of case-hardened low carbon or mild steel and have the hardened skin removed from the operative end face or faces of the tool. In one form, the end of a mild steel rod 1, Fig. 1, is flattened and pointed, as shown, and a slot 4 is cut therein after which the drill is case-hardened. The cutting edges 5 are then ground to give cutting rake and to remove the hard skin so that the cutting edges may subsequently be sharpened with a file. The shank may be provided with square and circular sections 6, 7, Fig. 3, for gripping in any type of chuck. In another form the twist drill shown in Fig. 3 is produced from a mild steel strip 8, Fig. 4, which is provided with unsymmetrical V-grooves 9 in its opposite faces and further staggered grooves 12, 12<1> in the grooves 9. The strip is then given a quick-pitch twist 13, the end trimmed, the strip case-hardened and the cutting edges 14 ground as in Fig. 1. The central web 10 of the drill is of such thickness that the hard skin 11 extends completely therethrough and allows the web to break away at the operative end to give the effect of the slot 4 in Fig. 1. The grooves 9 may be symmetrical or may be replaced by a deeper groove in one face only, and the grooves may be formed by rolling &c. The edges 8<1> of the strip may be arranged at an angle other than a right-angle to the faces in order to provide acute angles on the leading edges, or the faces may be formed concave as shown in Fig. 6. The strip may be buttwelded to the shank, or the shank end of the strip may be left untwisted and built up by securing further strips to the faces. Twist drills may be produced by helically grooving a cylindrical rod and then producing a central groove or grooves to provide the thin web 10.

Title: Improvements in or relating to motion transmitting devices
IPC: G05G1/00
Filed: 1945-05-28
Abstract: 593,265. Variable-speed and worm gearing. BYFORD, M. S. May 28, 1945, No. 13341. [Classes 80 (i) and 80(ii)] [Also in Group XL] A worm drive mechanism suitable for tuning condensers and similar components in radio equipment in which a slow or fast rate may be transmitted from a driving to a driven shaft comprises a driving shaft 17 with a worm 14 mounted thereon engaging with a wormwheel 10 on the driven shaft 11. The worm is mounted upon the shaft 17 my means of a screw thread 16 and is driven thereby through a pin 20 engaging a projection 21 so that the shaft 17 has approximately one revolution of relative movement with respect to the worm which moves the worm axially as a rack to rotate the worm wheel at a slow speed. On the pin 20 engaging projection 21 the worm drives the wheel 10 in the normal manner at a faster speed. In a modification the slow drive may be provided over more than one revolution of the driving shaft by providing a pin and projection at each end of the worm. In a further modification the screw thread connection between the shaft and worm is dispensed with and a driving pin moves the worm axially against spring pressure for the slow drive by engaging a helical cam surface on the end of the worm. The worm wheel 10 is formed in two parts with a spring connection 27 and one end of the worm is formed as a split resilient sleeve 29 to take up backlash.

Title: Improvements in or relating to electric tumbler switches
IPC: H01H23/20
Filed: 1952-05-27
Abstract: 772,783. Tumbler switches. WARD & GOLDSTONE, Ltd., and COUYOUMDJIAN. A O May 27, 1953 [May 27. 1952], No. 13368/52. Class 38(5) A switch which may embody the  features of the switch disclosed in Specification 772,781 comprising a dolly 6 pivoted at 15 and floatingly carrying a bridging contact 5, is characterized in that the spring 12 (or. a s shown two superimposed springs) which engages the dolly end 10 to impart a snap-action is mounted on the base 8 such that it may move lengthwise to a limited extent with the dolly when the latter is operated. The construction ensures a perceptible "feel" in the switch operation. The base 8. Figs. 1, 3, has a trough 11 with narrower ledges 13 formed at the ends on which tongues 17 of the spring 12 rest. When the dolly is operated the Spring 12 moves with the dolly end 10 until it is arrested by end faces 18 of the trough 11, the end 10 then riding over the spring apex 14 to give a snap-action. Since the faces 18 are in line with the edge  of the ledge 13 there is no rubbing between the spring and the base 8. In a modification (Fig. 5, not shown) the ledges have the same width as the trough and are bisected by a vertical rib, and the ends of the spring are slotted to freely embrace the ribs, lengthwise movement of the spring thereby being limited by engagement between the bottom of a slot and its rib. In a further modification, Fig. 6, the end wall 22 of the ledge 13 limits movement of the spring 12 and the ledge is downwardly inclined to permit uninterrupted deflection of the spring.

Title: Long-playing sound record and means for producing the same
IPC: G11B3/00
Filed: 1927-10-31
Abstract: 310,790. Sykes, A. F. Oct. 31, 1927. Divided on 310,821. Feed mechanism; disc-records; turntables; recording devices, supporting; tools for recording.-Provision is made for varying the pitch, and also if desired the depth, of the sound grooves during recording to facilitate the production of long playing records of fine pitch by temporarily increasing the pitch when loud passages involving increased amplitude are being recorded. The recording device 4, Fig. 2, is pivoted in a hinged bracket 5 and traversed to swing across the turntable 3 by a link connection 9 with resilient attachment 40, Fig. 3, to a sliding carriage 36 having a part nut 38 engaging a traversing screw 27 driven by gearing and belt 35 from a motor in the traversing gear box 25. The operator can vary the pitch at any desired time by rocking a pivoted lever 22 adjustably connected by a Bowden wire connection 23 with the brake 46 of a governor 49, Fig. 5, controlling the motor driving the traversing gear. Movement of the lever 22 may also operate an adjustably connected link 18 to adjust the screw pivot 14 supporting the swing arm 5 carrying the recording device and thereby vary the depth of the sound groove simultaneously with the variation of pitch. Alternatively, the depth of cut may be varied by tilting the turntable, which for this purpose is mounted together with its driving motor 55, Fig. 8, in a pivoted frame 52 which can be tilted by an adjusting screw 58. The screw 58 may be connected by Bowden wire mechanism for operation simultaneously with the pitch adjustment. The mechanism described in this Specification is substantially identical with that described in Specification 303,759 applied to an electromagnetic recording device. Specifications 263,502 and 305,067 also are referred to.

Title: Sheet feeding apparatus for copy machine
IPC: G03D3/00
Filed: 1974-03-27
Abstract: 1470531 Machinery safety devices; rollers ADDRESSOGRAPH MULTIGRAPH CORP 27 March 1974 [11 April 1973] 13696/74 Headings F2J and F2U In a photocopying machine, in which an original sheet in contact with a sensitized copy sheet is fed into a roller assembly 24 comprising driven lower wheels 34 on a fixed axis and driven upper rollers 30 on a floating axis, each upper roller has a soft resilient periphery normally brushing against the original sheet surface, but these rollers can be deflected to a raised position in response to entry of a foreign object, and the operator can reduce the rotation speed of the rollers by means of manually-actuated switches 102, 104. By further actuation of manual switches the operator may restore normal speed or obtain reverse drive at low speed. In addition to the resilient periphery, each upper roller has wheels 31, 33 which may bear against lower wheels 34. The soft resilient roller covering may consist of a tufted brush of nylon bristles 62, secured to a polystyrene core. Alternatively it may comprise a sleeve of polyurethane foam over a tubular core, or a soft-surfaced belt may be used in place of a roller. The operator may insert his fingers against the soft covering in order to manipulate and align the original sheet with the copy sheet and by the fingers may partly raise the upper rollers when slippage is required. The operator may choose to carry out this task at a reduced speed or forward feed, selected by manual switch 102 or 104, and full forward speed may be restored simply by a subsequent actuation of either switch 102 or 104. Furthermore, the operator may choose at any time to arrest the drive and cause it to feed in reversed direction at reduced speed, by manual actuation of a push-button switch 108, and full forward speed may be restored simply by a subsequent actuation of switch 108. Since the soft roller is arranged to accept the intended intrusion of the operator's fingers for the foregoing purposes, there is a risk of injury to the operator if the fingers were entered to a further extent, and also a risk of damage if objects, e.g. rulers, were drawn into the machine. Protection against these risks is provided by two control means 64, Fig. 4, located one at each end of the upper roller shaft 32, each comprising a limit switch 80 which becomes actuated when a shaft bushing 66 reaches its furthest upward travel in a guide block 68. Actuation of switch 80 causes drive to be reversed at slow speed, until normal forward drive is restored by actuation of manual switch 108.
