Title: Improvements in or relating to apparatus for the production of multi-page products from single sheets
IPC: B65H45/30
Filed: 1946-08-16
Abstract: 617,218. Folding and pasting sheets. McGLENNON, Ltd., F.. and WICKS, W. E. Aug. 16, 1946, No. 24445. [Class 100(i)] In the production of books &c. by the multiple folding of sheets, a device for applying a line of paste &c. to a sheet along its final fold line is movable into and held in operative position in synchronism with the folding-device. Paste is applied by a grooved wheel 21 mounted on a lever 28 oscillated between the paper and a feeding wheel 18 revolving in a paste-tray 15, by a cam follower 31 engaging a cam 35 on a shaft 33. A further cam, follower and link 37, 38, 39 operate a folder blade 6, so that the paste is applied at the moment when the paper is being pressed through a slit 8 in the machine table towards gripper rollers 9, 10 and to tapes 11 feeding the sheets to a second folding- machine. The sheets, introduced sideways by grippers (not shown), and endless bands 5 are positioned by stops about the slots 8 with the paste line below the pasting-wheel centrally positioned over one half of the sheet. In sixteen-page booklets, additional pasting apparatus is used to paste the other side of the sheets. The supply of paste can be regulated by adjustment of a scraper 23 mounted on a vertically movable arm 24, and a clearance hole 40 is provided in the table to prevent the table becoming pasted in the absence of a sheet. In a modification, the synchronous action of the paste-wheel can be effected by replacing the cam mechanism 35, 31, 29 by an extension on the blade 6 which depresses the hub of the pasting- wheel into contact with the paper on its folding stroke.

Title: Improvements in and relating to the hydrogenation of coal
IPC: C10G1/00
Filed: 1927-09-17
Abstract: 306,564. Lander, G. H., Sinnatt, F. S., and King, J. G. Sept. 17, 1927. Grant of Patent refused. Hydrogenation, destructive. - Coal is treated prior to destructive hydrogenation to remove part of its content of fusain or durain. The proportion of fusain present in the coal is reduced by removing the finely divided portion of the coal, e.g. the coal is crushed to pass through an # inch mesh screen and that portion is retained for treatment which will not pass through a <1>/60 inch mesh. The fines may also be separated by air blowing, washing, froth flotation, &c. The content of durain is reduced by hand picking. In conjunction with the above treatment the caking properties of the coal may be modified in various known ways, e.g. by preliminary hydrogenation as described in Specification 301,720, by preheating in absence of air to 100-350‹ C. by heating in presence of air, oxygen, steam, hydrocarbons, or inert gases, under pressure to 800‹ C., by exposure to air or oxygen for long periods, or by oxidation in presence of reagents such as ozone, halogens, solutions of ferric chloride, potassium permanganate, hydrogen peroxide hypochlorites, bleaching powder, or nitric acid.

Filed: 1966-06-02
Abstract: 1,149,732. Standing wires and fibres. CENTRALNE BIURO KONTRUKCJI KABLOWYCH PRZEDSIEBIORSTWO PANSTWOWE. 2 June, 1966 [3 June, 1965], No. 24645/66. Heading D1T. Wires or fibres are stranded by passing them from delivery spools "C", over guide rollers 2, 3, 4 mounted in rotating double twisting frame 8, through traverse 5 and then winding the double twisted line onto the twister drum 6. The line is then unwound from drum 6 and passed over rollers 4, 3 and 2 where it is double twisted again, passed through traverse 9 and wound onto drum 10. The twist pitch of the wires during the first winding onto drum 6 depends on the state of filling up of this drum since it is driven at constant speed. However the drums 6 and 1 are constructed to have the same dimensions and are driven at the same constant rotational speed and thus the quadruply twisted line has a constant twist pitch along its entire length.

Title: Fluid flow control system
IPC: A61M5/168
Filed: 1975-06-11
Abstract: 1516111 Automatic control IVAC CORP 11 June 1975 [12 Aug 1974] 24944/75 Heading G3R The flow of drops of fluid for parenteral administration is automatically controlled by varying the width of pulses which regulate the flow in response to the detected drop rate, the pulses being at a high, preferably non-integral, multiple of the drop rate, and the control signals are in digital form. The desired flow is determined by selecting a pulse frequency on a generator 18. Each pulse operates a control device 15 (a clamp, a peristaltic pump or a pump driven by a stepping motor, in which case each pulse from 18 releases a burst of driving pulses). The duration of each pulse is automatically increased in steps by device 21 until a drop is detected (by photo-electric means), whereupon the duration is decreased by a fixed amount. The system stabilizes when the average pulse width per cycle, and hence the flow, is such that the drops occur at the fixed ratio to the set frequency. A circuit 23 sets an ultimate limit on pulse duration, to prevent continuous flow, and an alarm is given for any of the events shown at 14. Details of the circuits are given. Reference has been directed by the Comptroller to Specification 1361062.

Abstract: 458,997. Moving signs. TREGONING, C., 228, Agar Road, Carn Brea, Cornwall. Sept. 9, 1935, No. 25054. [Class 3 (i)] A display, advertising, amusement, or like device comprises a plurality of lamps, balls, &c. 1, each mounted at the extremity of a radial spoke 2, the spokes being of different lengths and being carried by two hubs 3, mounted one at each end of an axle 61. Means are provided for rotating the axle 61 both about its own longitudinal axis and about an axis at right angles thereto, or for giving either one only of these rotations, thus imparting to the lamps, &c. an involved and changing motion further complicated by switching on and off various lamps, when such are employed. The axle 61 is rotated about its longitudinal axis by bevel wheels 64, 65, the wheel 64, being carried by an inner vertical shaft 6 driven by a worm 19 rotated by a motor 15. The axle 61 is given its other rotation by a hollow shaft 5 surrounding the shaft 6, and supporting the whole of the axle 61 with its spokes and lamps, head casing 4, &c. The shaft 5 is rotated through a worm 20 by a separate motor 14. The motors 14, 15 are excited in any desired predetermined sequence or combination by a switch rotated step-bystep by a ratchet-wheel actuated by a pawl carried by a pivoted arm oscillated by a link 38 the other end of which is rotated by a pin 37 on a crank-disc 36 mounted on a spindle 32 turned by two pawl-and-ratchet wheel one-way drives 44, 46 and 45, 47. The pawls 44, 45 are carried respectively by pinions 39, 40 meshing with wheels 42, 43 on the shafts 6 and 5 respectively. The spindle 32 is thus being driven at any given moment by the shaft 5 or 6, which is rotating the faster in a positive direction at that moment. When lamps are employed, their current passes through two sets of brush-ring contacts, one 49, 51 on the shaft 5, and the other 56, 59 on the axle 61, and their switching on and off may be effected by any form of automatic switch, such as that employed for controlling the motors 14, 15. Ball bearings are employed throughout, and cover plates 63 for the hubs 3 and 9 for the angle-iron framed base 8 are provided, a stuffing-box 12 being fitted to prevent rain entering the base down the exterior of the shaft 5. The spokes 2 may be stayed by rods 69. When lamps are used the sockets may be protected by rubber sleeves, and when balls, &c. are fitted these may be of rubber, and be illuminated externally. Specification 151,759, [Class 3 (i)], is referred to.

Abstract: 599,989. Dehydrating food products and the like. STEVENS, A. H. (Dehydration, Inc.) Sept. 27, 1945, No. 25056. [Class 34 (ii)] [Also in Group VI] Material to be dried (e.g., sliced carrots) enters the drying apparatus 10 on a conveyer 13 and is preheated by exhaust gases in the exit chamber 16. The material is thereafter conveyed through the apparatus by endless belts 15, 30, 45, 60, 75, and 85. Hot air or gases travel concurrently with the material at each level, but in the reverse succession of levels so that the material entering with high moisture content is met by the hottest discharge gases and as the moisture is progressively removed the material passes through relatively cooler drier gas at each stage. By arranging for the material and gases to travel concurrently through each stage the lighter and more quickly dried particles are carried forward by the high velocity of the gases while the heavier particles continue on the conveyer. Nozzles 90, 96, on the last conveyer 85 direct a blast of drying gas through the conveyer to separate and mix the material before discharge through a door 98. Multiple blowers 26, 38, 52, 67, 82, 92, 96 direct the drying gas through the plenum chamber 10 which is heat insulated. Additional heat for drying is supplied by steam heating coils 23, 33, 48, 63, 78 above the conveyers and by electric heaters 24, 34, 49, 64 immediately beneath the conveyer belts. The drying gas is heated by steam coils 99, 100, 101. The fan intake ducts are situated above the conveyer in such a manner that the discharge end of each conveyer is in a quiet zone so that the material falls vertically from one conveyer to the next, the conveyers being staggered for this purpose. The creation of a quiet zone at the discharge end of each conveyer is assisted by bleeding part of the drying gas to the plenum chamber by the provision of apertures 41, 55, 70, 80.
