Abstract: 921,571. Packaging. PAPER SACKS Ltd. March 6, 1961 [March 31, 1960], Class 94(1). [Also in Group XXX]. Articles in a single file on a conveyer belt 31 are acted upon so as to be discharged in three files each of four articles F 1 , F 2 , F 3 , (Fig. 2). The articles are carried by the conveyer 31 until the leading article engages a removable abutment 32 (top of Fig. 2). An abutment 33 operated by a cylinder 39, (Fig. 3), displaces the articles 1-4 laterally (2nd diagram, Fig. 2) and while the articles 5-8 proceed on to the stop 32 the articles 1-4 proceed until engaged by a fixed stop 43 (3rd diagram, Fig. 2). An abutment 34 then displaces the articles 9-12 and a bent over tail 34a of this abutment prevents further movement for the time being of the articles 13, 14,... so as to ensure a gap between the article 13 and the three groups of articles when they arrive in their final position (bottom of Fig. 2). The abutment 34 is returned to its original position and the abutment 32 is raised temporarily so that the groups 5-8 and 9-12 may proceed as shown in the (4th diagram of Fig. 2). The three groups of articles are then operated on by a member 44 which alternately pushes and pulls on alternate batches of articles. They are then engaged respectively by a ram plate 49 or 49<SP>1</SP> so that the batches are loaded into bags or sacks 51 held in openmouthed condition upon duckbills 52.

Title: An improved rapid acting valve for vacuum automatic braked vehicles
IPC: B60T13/46
Filed: 1924-05-08
Abstract: 216,118. Pinder, T. May 17, 1923, [Convention date]. Fluid-pressure.-An accelerating valve for automatic vacuum brakes, adapted for attachment to the train pipe or the bottom of the brake cylinder, comprises a casing A and a valve E which is actuated to admit air to the system by the movement of a. cylinder F in a fixed cylinder G, a band M on which is held between lugs N on the casing A, and lugs 0 on the cover B. A strap H attached to the base of the cylinder F passes through slots in the band M and normally rests on stops K on the cylinder G. When vacuum exists in the system, the spring J holds the cylinder F in the position shown, and the valve E is closed, but when air is admitted to apply the brakes, the pressure outside the cylinders rises more rapidly than in the space inside them, as the orifice R is small, and the cylinder F rises so that the strap H moves the valve E off its seat. The movement of the cylinder F continues until slots L in the two cylinders register, when the pressures inside and outside them equalise, and the cylinder F falls to allow the valve E to close by gravity.

Title: Improvements in or relating to rotary compressors
IPC: F04D29/28
Filed: 1947-04-29
Abstract: 628,052. Centrifugal compressors. DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and MOULT, E. S. April 29, 1947, No. 11500. Drawings to Specification. [Class 110(i)] Disc-supported bLades: guide blades.-In order to reduce the shock losses on impact of air or gas with the blades of a high-speed centrifugal compressor, the leading edge of each blade is wholly or partly cut back or inclined in the direction of air-flow to reduce the component of flow velocity, normal to the blade edge at the outer parts of the blade. The resulting blade edge may be curved, or formed of one or more straight lines, and may be arranged to give a constant Mach. number at all parts. Fixed guide vanes may be necessary to swirl the air approaching the impeller in order to make it enter the blades at the correct angle; they may be formed to give greater swirl at greater distances from the axis. The entry portion of each blade is in the form of a helix. The additional advantages of reduced centrifugal force and increased natural vibration frequency are obtained. Specification 578,190 is referred to.

Title: Improvements in or relating to apparatus for feeding and cutting paper webs
IPC: B26D1/62
Filed: 1948-04-27
Abstract: 651,146. Cutting-machines. AMBRUS, T. April 27, 1948, No. 11569. [Class 31 (i)] [Also in Group XVI] In an apparatus for feeding and cutting paper webs transversely into sheets having a rotary cutter device consisting of two shafts, one of which carries a roller having a blade let into a recess in the surface of the roller, and the other of which carries a mounting for a blade set at an angle to the axis of the shaft such that cooperation of the two blades produces a shearing cut which commences at one side of the web and proceeds to the other side, means are provided to alter the velocity ratio of the average rate of feed of the paper toward the cutter device and the speed of rotation of the cutter device, a looping device being provided in the feed to the cutter device, which is adjustable to ensure that notwithstanding the differences between the average rate of feed of the paper and the cutter speed, . the paper is travelling, at the moment of cutting, at the same speed as the cutter device. A paper web 11 is fed by feed rollers 12 and 13 to a rotary cutter device comprising blades 17 and 18 carried on rollers 19 and 20. The rollers 12 and 13 which feed the web at the average rate of feed are connected with the shafts of the rollers 19 and 20 by gearing (not shown), the velocity ratio of which may be varied. A pair of rollers 15, 16 which are only lightly pressed together, to permit the web to slip between them, are driven at the same peripheral velocity as the blades 17 and 18. A frame 25 mounted on a spindle 26 and driven in the clockwise direction at the same speed of rotation as the blades 17 and 18 comprises two side arms each supporting a slide block 29 adjustable along the arm by a hand wheel 31. The slide blocks 29 carry a looping roller 32 over which the web passes when the roller 32 is above the spindle 26. When the rollers 12 and 13 feed paper at nearly the same rate as the peripheral speed of the blades the slide blocks are adjusted inwardly. If the speed of the rollers 12, 13 is substantially decreased in order to vary the length of the sheets produced, then the slide blocks are adjusted an appropriate amount outwardly. When the frame 25 is in the lower part of its travel the web will be fed ,directly to the rollers 15 and 16 which will slip relatively to the web on account of its lower speed. When the roller 32 engages the web 11, the speed of the web will be either reduced or reversed, thus increasing the slip between the rollers 15 and 16 and the web due to the formation of a loop in the web. When the looping roller moves downwardly, web from the loop will be fed with reduced slip to the blades 17 and 18 by the rollers 15 and 16, such that at the moment of cutting the speed of the web is the same as that of the cutter device.

Abstract: 610,794. Protective cut-out arrangements. COMPAGNIE ELECTRO - MECANIQUE. April 16, 1946, No. 11735. Convention date, April 24, 1945. [Class 38 (v)] A line-section is prevented from being tripped out at both ends on external fault, by electronic tubes controlled from the remote section-end, a minimum of pilot wires being employed by interconnecting the grids and cathodes, respectively, of the two valves. Balanced or unbalanced symmetrical component filters 8, 81 at the section-ends are relatively-reversely connected to identical transformer sets, each comprising a saturable transformer 11, 11<1>, connected to the valve anode and trip relay 10, 10<1>, and an unsaturated transformer 13, 13<1> connected through a rectifier 14, 14<1>, which represses the positive half-waves, to the grid/ cathode circuit and to the pilot wires 15, 16. Due to the reverse connections of the filters, the anodes, on external fault, are positive alternatively and receive negative blocking bias over the pilot circuit from the remote transformer 13, 13<1>, so preventing tripping. With internal faults, the anodes are positive together when the rectifiers 14, 14<1> areoperative, and tripping occurs. With very short line-sections, or bus-bars, the pilot wires are dispensed with and both rectifiers 14, 14<1> feed the grid of a single valve 9, the anode of which is rectifier-connected to the transformers 11, 11<1> over a pair of trip coils, or, Fig. 3, a single trip coil 28 is connected to the junction of the rectifiers 25, 25<1> and has contacts for both or all, circuit-breakers connected to the bars.
