Title: Apparatus for gluing down the trailing end of a web roll of paper or the like
IPC: B65H19/29
Filed: 1975-02-18
Abstract: 1495445 Attaching web ends to rolls F PERINI 18 Feb 1975 [10 Sept 1974] 6825/75 Heading B8R A device for attaching the trailing ends of web rolls comprises a conveyer 1 supplying the rolls B1 to an inclined plane 5 into which the rolls are displaced by a pivotal arm 3, the rolls moving along the plane 5 formed by a pair of suction boxes 6, 7 cause their trailing ends to unwind. The unwound trailing ends are held flat by the action of the boxes 6, 7 and a blast of air delivered from a nozzle 38. When the unwound web rolls B3 have approached a pair of rotary members formed by an endless tape conveyer 10 and a main roller 9, which rotates faster than the conveyer 10, the rolls are rewound again under tension. The passage of the trailing ends between the boxes 6, 7 and across a space 26 is sensed by photoelectric detector means 32, 34. The latter cause a rotary brush roller 16, 18 to apply a predetermined length of spaced adhesive lines to the web rolls to cause the rewound trailing ends to be attached to the web rolls B3, which are then discharged on to a table 22. The photo-electric means 32, 34, and the conveyer 10 as well as the brush roller 16, 18 are adjustable to cope with rolls of different diameter. The brush roller may be replaced by a spray nozzle assembly located above the box 7, which is replaced by an adhesive catch tray.

Abstract: 815,943. Railway track crossings. ACIERIES DE PARIS ET D'OUTREAU. March 1, 1957 [March 15, 1956], No. 6832/57. Class 104 (1). A rail track frog crossing formed by a single unitary casting of hollow rectangular tubular form over the greater part of its length comprises a transverse upper wall integrally joined by two vertical side walls to lower base wall or sole which sole seats upon the track sleepers the top wall being shaped to provide the running and guard rails. The sole plate 4 has a series of apertures 7 along its length to facilitate the removal of the moulding cores. A series of ribs spaced along the length of the crossing 1 and inside the hollow section are all curved in the same direction. The rolling surfaces are convergent and inclined inwardly at 2 and inclined outwardly at 3. Raised edge portions on the top surface of the crossing, considered progressively from the right-hand side of Fig. 1, first form guard rails 10 and then converge to the crossing throat adjacent the frog point 9 and thereafter diverge away from one another to form running rails 2 leading out of the frog-crossing. The thickness of the metal in the various sections are the same along the length of the crossing and the side walls taper slightly from the rolling surface to the sole plate 4. The frog-crossing may be used in single frog-crossings such as railway track turnouts and also double-frog-crossings such as are used in conjunction with single frogs in diamond crossings.

Filed: 1947-03-11
Abstract: 640,512. Clothes driers. LOVELL MANUFACTURING CO. March 11, 1947, No. 6808. Convention date, March 6, 1946. '[Class 34(ii)] A tumbler drier with an electric radiant heater is provided with control means for turning the heater on at the start and automatically turning it off at the end of the drying cycle, and a thermostat responsive to the casing temperature for maintaining the circuit to the driving motor closed after the heater is shut off until the casing has cooled. In the construction shown the drier comprises a perforated drum 3 driven by a motor 4, and having a heater element 7 and suction fan 8. The drying cycle is started by a pushbutton 14 closing contacts which energize the heating element 7. When the casing has warmed up the thermostat 21 closes the circuit to the motor. As the clothes dry the temperature drop of the drying air across the drum decreases and at the required stage a thermostat 23 moves the push button to the open position thus breaking the circuit to the heater. The motor continues to rotate the drum until the temperature drops when the thermostat 21 opens. In a modification the rotation of the drum and blower motor are started simultaneously with the heater. A safety thermostat 17 is provided to break the heater circuit if circulation of air past the heater element is interrupted. Specification 605,574 is referred to.

Abstract: 453,501. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and DITCHAM, W. T., Almont, Baddow Road, Chelmsford. March 11, 1935, No. 7570. [Class 40 (v)] A valve modulating circuit comprises a wave amplifier 1 and a signal amplifier 2 connected in series across a divided H.T. supply 22, 23, and an impedance 26 is interposed between the junction of the supply sources and the junction of the valves. High-frequency chokes 5, 24 are interposed in each supply lead to the wave amplifier 1. The signal is applied to the grid of the amplifier 2 through a transformer 12 and condenser 13, and the negative grid bias of this valve is reduced as the signal strength increases by rectification of the signal in a full-wave rectifier 19 of which the load resistance 17 is in the grid circuit of the valve 2. In this way power consumption in the valve 2 is reduced when the signal is of low intensity. As the valve 2 operates on a straight part of its characteristic, the mean carrier amplitude does not vary with the signal strength.

Abstract: 1470401 Stackers H JUNGHEINRICH & CO MASCHINENFABRIK 20 Feb 1974 [21 Feb 1973] 7708/74 Heading A4T A mobile stacker 1 for stacking loads on high level shelves comprises a mast 5 by which a lifting carriage 6 is movable, the upper portion of the mast 5 being bendable as shown an arm 7 mounted on the carriage 6 for lateral displacement, a load carrier 9 mounted for pivotal movement about an axis 8 relative to the arm 7, the stacker further comprising means for determining the position of the lifting carriage relative to a nominal position of the stacker 1 in which the latter is aligned with a vertical stack of shelves, in order that the stacker 1 can be moved to compensate for the bending of the mast's upper portion so that the load carrier 9 can be aligned with a particular shelf. The said means comprises a first element 51 connected by an arm so the upper portion of the mast, the element 51 being a transmitter of optical, acoustic or radio signals, and a second element in the form of a series of elements 52, 53 ..., so that a signal beam 54 is transmitted from the transmitter 51 to the series of elements. When there is no bending of the mast upper portion the signal beam 54 is transmitted to the element 52 and when there is maximum bending of the mast upper portion, shown as 5", the beam 54 is transmitted to the element at the other end of the series. If the element 51 transmits optical signals the elements 52, 53 ... can be reflectors thereby providing a visual indication to the driver of the stacker as to the amount the stacker 1 must be moved in order to compensate for the bending of the mast. Advantageously, the second element is so responsive to the signal beam 54 as to cause a control signal to be applied via control means to the drive means of the stacker in order to move the latter in dependence on the extent that the mast bends. This control means could comprise a counter arranged to count the number of elements intervening between an element of the series which is illuminated or irradiated by the signal 54 and an element at one end of the series.
