Title: Paper perforator
IPC: B26F1/36
Filed: 1977-10-11
Abstract: The letter perforator has a base plate (1) with side cheeks (4, 4') which are bent vertically upwards. The pressure plate (6) is pivotably mounted in bearings (5, 5') of the side cheeks. A cross member (2, 22) is bent upwards from the base plate (1) and contains the die recesses (3, 3'). The side cheeks (4, 4') overlap, with projecting parts in which the bearings (5, 5') are arranged, the part (22) of the cross member (2, 22) which contains the die recesses (3, 3'). Furthermore, the perforating stamps are formed by hollow cylindrical pins (9, 9') which are pressed out of the pressure plate (6). This design makes it possible to produce the letter perforator in such a way that the latter can be stamped out of two relatively thin steel sheets, is of low height and has sufficient dimensional rigidity despite being produced in a simple manner. <IMAGE>

Title: Improvements in or relating to the manufacture of tipped cigarettes
IPC: A24C5/58
Filed: 1962-11-09
Abstract: 1,047,015. Cigarette-making machines. D. T. N. WILLIAMSON and MOLINS ORGANISATION Ltd. Nov. 8, 1963 [Nov. 9, 1962], No. 42457/62. Heading A2C. A. method of feeding tipping material in the manufacture of tipped cigarettes comprises the steps of feeding lengthwise a web of tipping material, cutting the web transversely of its length to sever desired lengths therefrom, and receiving and conveying the severed lengths on a conveyer to which they are held by electrostaticattraction. As shown a web W of cork tipping is drawn from a bobbin 1 over a. guide 3 between a drive roller 6 and a co-operating roller 5. The web is cut transversely by a fixed knife 9 and a co-operating rotary knife 7. A spring biased arm holds the web away from the knife 9 except during cutting when the arm is pivoted anticlockwise about a pivot 12 by a cam 14 rotatable with the kiife 7. The lower end of the web W is held between a drive roller 15 and co-operating rollers 16, 17 mounted on a spring-biased arm 19. During cutting the peripheral speed of the rollers 6 and 15 are equal but at other times the roller 6 is driven at a slower speed so that cut lengths L are separated. A conveyer comprising an endless band 23 of insulating material receives the cut lengths L. The band passes around rollers 24, 25 the roller 24 being driven so that the band 23 moves at the same speed as the peripheral speed of the roller 15. The band 23 runs over the surface of a block 26 which contains an upper central metal portion 35 of a width equal to that of the lengths L. The portion 35 is insulated from the remainder of the block by insulating material 36. The roller 24 is alos provided with a peripheral metal ring 37 electrically connected to portion 35 by a metal plate 39. The ring 37 is insulated from the remainder of the roller by insulating material 38. A positive potential of between 5,000 and 10,000 volts is applied to the portion 35 and ring 37 while two rollers 27 and 34 spaced slightly from the conveying surface of the band 23 are earthed. The lengths L are thus held on the, band 23 by electrostatic action. The lengths are gummed by an adhesive applier 28 and used to unite groups A consisting of double length mouthpiece filter portions flanked by two cigarette lengths which are fed on a conveyer 33. The conveyer 33 is spaced from the lower run of the band 23 by a distance approximately equal to the diameter of a group and travels at a slower speed than the band 23 so that the lengths L are rolled around the groups A.

Title: Equipment for the extraction and purification of the filling gases from coke ovens
Inventor: SCHULTE FRITZ
IPC: C10B27/04
Filed: 1961-11-29
Abstract: <PICT:0962125/C4-C5/1> In the operation of filling or discharging coke-ovens, a process for disposing of dust and/or tar laden gases thereby displaced comprises passing the gases through a zone in which they are intimately mixed with a liquid on the surfaces of a rapidly moving element and immediately separated from the liquid and allowed to escape.  Preferably, the gases are passed through a wet spinning element, e.g. a wire brush supplied with liquid.  The washing liquid may be water.  As shown, the apparatus may be applied to a multiple chamber coke-oven, the said apparatus being mounted on the platform used for the coke handling equipment.  A charging car 1 is arranged to travel on rails 2 and 3 along the roof 4 of the coke-oven and on this platform a combined gas extraction and purification apparatus in the form of a cyclonic brush-type gas washer 6 is provided.  The impeller wheel of the washer 6, which is provided with a circular brush, extracts the dusts and gases through a flexible pipe 7 connected with an opening 4b in the roof 4 of the coke-oven. The sludge from the washer is drained through pipe 11.

Abstract: 1,142,694. Bearings. FOUNDRY EQUIPMENT Ltd., and K. C. TECKIENBOROUGH. 9 Oct., 1967 [26 Sept., 1966], No. 42918/66. Heading F2A. A rectilinear-motion bearing is provided with pressurized-air between the relatively movable parts, has one of said parts moved by means of pressurized-air, and has the movable part guided along a predetermined path. In an embodiment a frame having sides 11 is supported by guideways 10 and carries a pattern and/or a moulding box (not shown). Each side 11 is provided with a bore 12 which connects with bores 35 in sides 36 of the frame; and is provided with a longitudinally extending rebate 13, the latter being connected to the bore 12 by means of ports 30. One of the bores 12 is connected, by means of two ports 16, to a double-acting jack 14, the cylinder 15 of which is integral with a side 11 of the frame. The cylinder 15 contains a piston formed by a gland 18 and a piston-rod formed by a tube 17. The cylinder 15 comprises ports 19 and 20 and the piston-rod comprises ports 17a and 17b, the latter being slidingly supported by glands 21 and 22 mounted at the ends of the cylinder 15. The tube 17 is attached to the stationary part at 28, 28 so as to allow a vertical displacement of the jack 14 when pressurized air is supplied between the frame and the guideways 10. The frame is guided by means of the tube 17 and also by means of members 25 and 26 which also serve to reduce the escape of pressurized air. In use pressurized air is passed through the tube 17 and through an aperture 23 therein to either the part 19 or the part 20 of the cylinder 15, according to the direction of movement required and is passed through non-return valves 37 into the rebates 13, via the bores 12 and the ports 30. Thus the pressurized air serves to actuate the movement of the cylinder 15 and consequently the frame, and also serves to raise the frame away from the guides 10.

Abstract: 1440209 Moulds AKITA KK 17 Sept 1973 [22 Sept 1972] 43461/73 Heading B3F A method of preparing separable mould parts for casting metal comprises forming a lip 8, Fig. 3, around the rim of a mould cavity in one part, the lip projecting so that it is deformed to provide a seal around the cavity when the parts are secured together, thus preventing the escape of metal and the formation of flash. The pattern 2, Fig. 2, for forming the cavity is covered with a plastics sheet 5 sucked into engagement therewith by vacuum connections 4. Sand 6 is then placed around the pattern and the mould made by vacuum formation as in Specification 17902/72. When the pattern is withdrawn the projecting lip 8 remains. A modified double-sided pattern, Fig. 5, has a vacuum connection 55 and produces lips 60, Fig. 8, which act as seals. The grooves in the pattern to form the lips are 0À5 mm. deep and 1-2 mm. wide.
