Title: Apparatus for classifying sheet material
IPC: B21D43/22
Filed: 1947-07-31
Abstract: 651,843. Conveyers. AETNA-STANDARD ENGINEERING CO. July 31, 1947, No. 20813. Convention date, Jan. 21, 1939. [Class 78 (i)] [Also in Group XVII Apparatus for classifying thin sheets of ferrous material at high speed comprises a substantially horizontal belt for conveying the sheets at high speed and an electromagnet disposed beneath the upper reach of the belt for holding the sheets down on the belt thereby preventing planing through the air. A strip of tin plate passes through a motor-driven edge trimmer, dust removing felt pads, a continuous gauging device, a roller level, pinch rolls and adjustable rotary shear. The sheets S then pass on to a conveyer belt 30 driven by a motor 31 running at a higher speed than the shear past a deflector 32 pivotally mounted on a shaft 33 and raised and lowered by a solenoid 34 controlled by the gauging device. The sheets pass to belts 35 driven at a slower speed by a motor 36, then on to belts 37 with further reduction of speed by the motor 38, thence to belts 39 at a slightly lower level and driven at a still slower speed by a motor 43, so that the sheets overlap. The sheets pass between concave and convex rolls 40 and 41, which are spring-urged into contact and one is driven. The sheets then pass over a driven roll 42 and are discharged in a pile on to the elevating platform 44, being guided by adjustable side members 47, a member 46 and an end stop 45. If a sheet of incorrect thickness passes the gauging device, the gauge, which comprises two small rollers, the distance between which varies and controls an electric supply to the solenoid controlling the deflector, which is raised and deflects the sheets downwardly past three guiding rollers on to a lower series of belts which operate in the same manner as the upper series. Magnets M and M<1> are disposed beneath the belts at the ends and intermediately are adjustably mounted. The coils for the magnets M and M<1> at the ends of the belts are incorporated in recesses in the brackets supporting the end pulleys. The magnets intermediate the ends are movably mounted on rods connecting the end pulley brackets. A slidable member is mounted on these rods at one end, and connected to a fixed frame member, so that by sliding the member along the rod the belt pivots about the pulley shaft at the other end, the shaft and bracket member being concentrically mounted, and the height of the belt is adjusted. The belt can be tensioned by moving the brackets along the rods by means of a nut. The motor mechanism and belts are mounted on a girder extending along one side of the apparatus. The speeds of the belts may be independently or simultaneously adjusted by a Ward-Leonard control system.

Title: Improvements in or relating to door- or gate-operative mechanisms
IPC: B66B13/24
Filed: 1948-08-09
Abstract: 644,961. Door-operating appliances. EXPRESS LIFT CO., Ltd., and KRUGER, S. Aug. 9, 1948, No. 20975. [Class 65(i)] In a power-operated door-actuating mechanism including two members coupled by a spring-loaded member which allows the members to be disconnected for manual opening of the doors in emergency, the spring-loading is arranged to be strong during normal operation but weak when the door is closed, so that the disconnection is made easy in the latter case without reducing the effectiveness of the coupling for power operation; the members are preferably parts of a telescopic link. In the embodiment shown, two sliding doors of a lift, supported by carriages 12, are operated from a motor-driven shaft 2 by cranks 1 and connections 5, 7, 8, 10 pivoted to the cranks and the carriages; .the members 5, 7, 8, 10 normally form a rigid unit, the parts 5, 7 being permanently rigid, parts 8, 10 being adjustably fixed together, and part 8 being slidable within the part 7 but locked thereto by a detent 14 engaging a notch in the part 8. The detent 14 is slidable, against a strong spring 18, in a lever 19 pivoted on the part 5, the other end of the lever being attached to a collar 20 slidable, against a weak spring 21, on a shouldered rod 23 engaging a lever 24 pivoted to the member 5 at 25 and carrying a roller 26; when the doors are closed, as shown, there is sufficient space between the collar 20 and the shoulder of the rod 23 to allow the detent 14 to be disengaged by moving the lever 19, but as the mechanism operates to open the doors the ends of the cranks 1, formed as a cam, engages the roller 26 and moves the lever 24 to close the space between the collar 20 and the shoulder, so that the lever 19 cannot be moved and the detent can only be released against the strong spring 18. A detent 17 engages a notch in the part 8 to prevent complete separation of the parts 7, 8 when the detent 24 is disengaged. Specifications 572,189 and 579,228 are referred to.

Abstract: 1307657 Roughened polyolefin films NISSHIN BOSEKI KK 19 April 1971 [2 Feb 1970] 21044/71 Heading B5B [Also in Division B2]  A polyolefin film, e.g. of h.d. or l.d. polyethylene or isotactic polypropylene, is passed through a bath of a heated inert liquid followed by a bath of a liquid having swelling or solvent action on the film and which is at a temperature not exceeding that of the inert liquid, whereby the surface is modified, e.g. roughened, and is more ready to accept printing, writing and adhesives. The second liquid may contain a synthetic polymer, e.g. nylon, polystyrene, PVC or a polycarbonate, which forms a thin coating on the film, giving surface properties as above. The treating liquid is preferably less dense than and immiscible with the inert liquid whereby it is floated thereon, and the film passed directly between the two liquids. The inert liquid may be, e.g. mercury, Wood's metal or saturated FeCl 3  solution, and the treating liquid, e.g. tetra- or trichloroethylene or ethylene chloride. Other liquids are listed. The treated film readily accepts coatings, e.g. of butadienestyrene latex containing kaolin clay or PVAcetate latex containing CaCO 3 .

Title: Vending machine for books and other articles
IPC: G07F11/16
Filed: 1945-08-17
Abstract: 597,377. Coin-freed article-delivery apparatus. WITT, H. F., and HALL, R. D. Aug. 17, 1945, No. 21054. [Class 27] Articles such as books are displayed on a shelf traversed by an ejector which is first brought opposite the article required, and then operated to tip it into a delivery chute. The apparatus shown has a series of superposed shelves 9 each with an ejector 13 in the form of a helical spring secured to a carrier 12 slidable along a rockable actuating bar 11 extending lengthwise of the shelf. The carriers 12 are interconnected by a vertical rod 18 connected through chain and sprocket mechanism 16, 17, 29 with a selector handle. The actuating bars 11 are connected through cranks 38 with corresponding push rods 37 and a cam 34 is movable along a motor-driven shaft 35, to engage it with any one of the rods, by turning a second selector handle 32. In operation, the first selector handle is turned to bring the ejectors into line with the article required, whilst the second handle is adjusted to engage cam 34 with the push-rod 37 corresponding to the shelf carrying the article. A coin is then inserted which closes the motor circuit so that the cam 34 rocks the appropriate actuating bar 11 and ejector 13 to tip the article into a delivery chute 14. A cam 46 on the shaft 35 detaches the first selector handle, whilst the motor is running, in order to prevent the ejector being traversed. At the completion of one revolution of shaft 35, a cam 42 actuates a push-rod 43 to discharge the coin and break the motor circuit. The mechanism as above described may be arranged on each of two or more faces of a box-like casing.

Title: Cooled Vane Structure for High Temperature Turbines
Inventor: KERCHER DAVID MAX
IPC: F01D5/18
Filed: 1967-05-05
Abstract: 1,188,401. Turbine and like blades. GENERAL ELECTRIC CO. May 5, 1967, No.21135/67. Heading FiT. A cooled turbine or like vane has a plurality of radially extending, axially spaced passageways formed in the body of the vane, one being provided adjacent the leading edge 37 and one adjacent the trailing edge 38, the remainder being intermediate the leading and trailing edges and inter-connected to form two serpentine passages 42, 43, 44 and 45, 46 each having a heat transfer fluid inlet 64, 65, a plurality of radially spaced openings 57, 58 interconnecting the first serpentine passage with the leading edge passageway 40 and the second serpentine passage with the trailing edge passageway 41, and a plurality of outlet passages 70, 72, interconnecting the leading edge passageway 40 with outlet openings in the leading edge region of the vane and the trailing edge passageway 41 with outlet openings in the trailing edge region of the vane. The invention is described with reference to a gas turbine rotor blade but is equally applicable to the vanes of gas turbine nozzle diaphragms and to vanes used in other high temperature turbomachines, such as high pressure compressors. The vane body 33 is aerofoil-shaped and the passageways 40 to 46 are radial holes extending inwardly from the radially outer end 50 of the vane body to the base portion. And end wall plate 52 is located in a recess 51 at the outer end 50 to close, except for bleed openings 53, the outer ends of the passageways 40 to 46. The openings 57 inter-connecting the radial passageways 40, 44 are sized to throttle flow of cooling fluid so as to enhance convection cooling at the leading edge region. Rows of radially spaced passages 70a, 70b inter-connect the leading edge passageway 40 and the convex and concave side wall surfaces 35, 36 respectively, two further rows of such passages 70c inter-connecting the passageway 40 and the leading edge 37. The axes of the passages 70a, 70b form an acute angle, preferably less than 30 degrees, with the surfaces 35, 36 so that the cooling fluid is discharged axially downstream and the axes of the passages 70c form an angle of approximately 30 degrees with the leading edge 37 so that the cooling fluid is discharged radially outward along the leading edge 37. The convection cooling at the leading edge region is supplemented by boundary layer cooling since the angular orientation of the passages 70 causes the discharged cooling fluid to be trapped in the boundary layer, thus insulating the vane body 33 from the hot combustion-products. The cooling fluid is relatively cool compressed air bled from an annular chamber which surrounds the combustion space of the gas turbine.

Title: Improvements in or relating to remote control systems
IPC: H02J13/00
Filed: 1928-07-25
Abstract: 296,664. Associated Telephone & Telegraph Co., (Assignees of Hershey, H. E.). Sept. 3, 1927, [Convention date]. Selective distant control systems; tell-tale apparatus.-Relates to a remote control system in wihich a plurality of switching devices are selected, supervised and controlled from a remote station. Fig. 1 shows the control station and Fig. 2 the controlled station. Supervisory arrangement. Supervision is effecting by closing switch 7 and selecting by impulse transmitter 10 a contact on a stepping switch having a number of banks and a motor magnet 109. Switch 7 energizes an impulse relay 104 and thus a slow release relay 105. Selector 10 impulses relay 104 which controls a series slow release relay 107 and the motor magnet 109. Relay 107 energizes relay 108 which opens the control circuit at springs 131, 132, throughout the train of impulses at the conclusion of which relay 104 re-energizes deenergizing relays 107, 108 and motor magnet 109. The energization of relay 105 causes relay 106 to operate and extend the supervisory and control circuits through its contacts 127, 128. The wipers 133 - - 136 close a circuit for an ammeter 12 to battery 114 which is deflected in direction to indicate whether the circuit breaker is open or closed and in amount to indicate that the correct circuit-breaker has been selected by means of a resistance 153 associated with the circuit breaker. Other circuit breakers are associated with corresponding resistances 154 - - 156 adapted to cause differing deflections on the ammeter 12. Corrections for variation of battery voltage are made by resistance 14 while the resistance 15 is utilised to allow for the differing resistances of different lines. Operation of circuit breakers. To open the selected breaker springs 2, 3 are closed and spring 1 opened of the key K operating polarised relay 140 from battery 20 to operate the selected auxiliary relay 172. The circuit breaker is closed by the operation of springs 4 - - 6 of the key K causing operation of relay 140 in the opposite direction to operate the selected auxiliary relay 174. Restoration of the key K in each case causes an indication to be given on the ammeter 12 which may be recorded by a peg in holes 28. The opening of contact 7 causes restoration to normal by de-energization of relays 104, 105. This completes the circuit of the release magnet 110 which restores wipers 133 - - 136 to normal. Tell-tale arrangement. In the event of movement of a circuit breaker as by an overload the circuit of the relay 103 is momentarily opened and this relay is de-energized and actuates relay 101 which closes the circuit of a ringer 9 energized from transformer T, Closure of the operating switch 7 operates relay 102 by current from battery 113 and re-energizes relay 103 which locks itself. The circuit breaker in question can be ascertained by dialling the digit a number of times to ascertain the position of each circuit breaker successively.
