Title: Device for closing bag ends
IPC: B65B7/08
Filed: 1936-08-12
Abstract: 477,858. Closing filled bags. AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. Aug. 12, 1936, No. 22230. Convention date, Aug. 30, 1935. [Class 94 (i)] The machine closes bags by producing a transverse coiled fold in the material of the top of the bag. The top of the bag may be collapsed and folded in a direction opposite to that of the subsequent coiling by apparatus such as is described in Specification 477,859. After the top of the bag A has been initially creased, it is fed to the left, Fig. 2, beneath plates 35 which maintain the folds in their downward position ready for engagement by the twisting mechanism. The mechanism comprises a yoke 48, Fig. 4, slidable on bars 45, Fig. 6, arranged transversely to the travel of the bags. One leg 65 of the twisting mechanism is mounted on a shaft 63 having a loose pinion 62 engaging a gear train 66, 68 and with a segment 53 on the driving shaft 46. The other leg 73 is mounted on a shaft 69 on which the gear 68 is mounted. Upon the arrival of the bag, the cross-head and associated parts are moved by links 50, 52 into the engaging position, Fig. 4, the legs 65, 73 being spaced as shown in Fig. 9 so as to pass one each side of the flattened bag top. The sector 53 is rotated clockwise to the position shown in Fig. 10, carrying the leg 73 to a position of parallel juxtaposition with that of the leg 65. The rotation of the gear 68 is thus prevented, and the further rotation of the sector 53 to the position shown in Fig. 11 causes the gear train to rotate bodily in the direction of the arrow B and to double or coil the fold alreadv made by the first part of the operation, the legs rotating about one edge of the leg 65. The legs are now withdrawn transversely from the fold and the bag moved beneath bars 74, Fig. 2, moved by a cam 76 and arms 75, 77 so as to follow the bag and hold down the fold.

Title: Improvements in the control of hydraulic forging presses
IPC: B30B15/16
Filed: 1959-06-30
Abstract: 888,279. Hydraulic presses. SCHLOEMANN A.G. June 30, 1959 [July 1, 1958], No. 22369/59. Class 69 (2). [Also in Group XXII] An hydraulic forging press has a plurality of working cylinders 2, 3, 4, operable selectively to suit the pressing load required, the selection being performed automatically by measuring devices 175, 176 interposed in the pressure water pipes 168, 167 leading to the cylinders. The press can perform hand-controlled forging, automatic single or repetitive forging strokes for elongating a billet or smoothing of the billet by quick strokes. Supply of low-pressure water from pipe 155, for prefilling and retracting, and of high-pressure water from pipe 156 for the actual forging, is controlled by lift valves 144-149 actuated by cams 134 on a shaft 131; discharge of water to pipe 163 is controlled by lift valves 136-142 actuated by cams 133 on a shaft 129. Shafts 129, 131 are driven through gearing 126, 127, 128 by a motor 123 controlled through amplifier 121 and regulator 122 from actual and desired value rotary stroke-control units 115, 116 which receive signals through line 179. A hand-control lever 119 is also provided. The platen 1 first performs a filling stroke controlled automatically by an electronic switch 24, and using low-pressure water. The actual movement of the platen is detected through link 7 and gearing 8 by means 10 which transmits to the electronic switch 24 where it is compared continuously with a pre-set desired value and accordingly corrected. The filling stroke limit is set by potentiometer 19. Thereafter, a first pressing stage begins, using high-pressure water supplied to cylinders 2, 3 only, the stroke movement being controlled automatically by an electronic switch 25. If the pressure is insufficient, a measuring box 175 responsive to pressure or flow transmits a signal through line 178 which trips a pressure-responsive switch 72 for initiating a second pressing stage wherein high pressure water is supplied to cylinder 4 only. If the pressure is still insufficient a second measuring box 176 transmits a signal through line 177 and trips a pressureresponsive switch 73 for initiating a third pressing stage wherein high-pressure water is supplied to all cylinders 2, 3, 4. The limit of downward movement is pre-set by a potentiometer 20. The potentiometers 18, 19, 20 may be adjusted by servomotors during the operation of the press. Platen 1 is retracted by lowpressure water supplied to cylinders 5, 6, the stroke being controlled automatically by electronic switch 23 and the up-stroke limit being pre-set by potentiometer 18. For single strokes push-button switch 56 is actuated and for repetitive strokes, push-button switch 57 is used which brings into circuit a time relay 82.

IPC: F02B71/00
Filed: 1954-07-30
Abstract: 762,429. Free piston compressors. PETERSEN, H. July 30, 1954, No. 22378/54. Class 7 (2). In a combined free piston internal combustion engine and air compressor assembly having two axially parallel cylinder groups and opposed stepped pistons connected to opposite ends of two oppositely disposed rocking levers mounted between the cylinder axes one cylinder group is constructed as a two stroke engine with scavenging and charging pumps arranged symmetrically at the ends of the group the other cylinder group being constructed as a single stage or two stage compressor and the other cylinder group provides at least one swept volume for compressing the delivery air and at least one swept volume for storing return energy. In Fig. 1 the power cylinder is indicated at 13 and compressor chambers at 17, 18. Annular spaces 26, 27 form pneumatic accumulator spaces, while the inner space 23 forms a compressor. Shafts 10, 11 may be used for driving a fuel injection pump or a lubricating oil pump. In a modification the annular spaces are formed as compressor spaces and the inner spaces as accumulator spaces. In another modification Fig. 3 spaces 26b, 27b form during the first part of the stroke compression spaces and during the latter part of the stroke accumulator spaces. The air is further compressed in a compressor 23b after intercooling in a cooler 45. The inner swept volume may compress the delivery air in a first stage in the first part of the stroke and may store return energy in the second part of the stroke whilst the annular spaces further compress the delivery air in a second stage in such first part of the stroke. The swept volumes used for storing the return energy may be connected by means of slots arranged laterally in the cylinder walls to the atmosphere or to a chamber subjected to pressure.

Title: Method of producing metal oxides
IPC: C01B13/22
Filed: 1960-10-03
Abstract: A process for the production of a finely divided oxide of a Group 3 or 4 metal (particularly titanium, but Si, Zr, Sn, Al, Hf and Th are also mentioned) by the high-temperature oxidation of a volatile metal halide comprises <PICT:0969619/C1/1> introducing a stream of said volatile metal halide into a free oxygen-containing hot reaction space and simultaneously introducing into said reaction space, adjacent the point of entry of said metal halide stream and in a direction substantially tangential to the cross-sectional area of said metal halide stream, separate streams of a burning fuel and an auxiliary gas. The fuel may be CO, natural gas, a hydrocarbon fuel, a suspension of carbon particles or sulphur chloride, whilst the auxiliary gas may be air, Cl2, N2, CO2 or a noble gas.  The oxygen for the reaction may be supplied separately or admixed with either the halide stream or the burning fuel.  A suitable apparatus for the reaction is illustrated in Fig. 1.  Vertical reactor 2 consists of an elongated steel column having a cover 4 and a floor 6 and is lined with firebrick 8. Near the top the reactor is provided with a tangential port 10 which contains an internal burner 12 mounted on face plate 14, and which supplies burning fuel to the reactor.  Port 10 terminates at the inner surface 3 of the top part of the reactor, and diametrically opposite to port 10 is another tangential port 16 through which enters the auxiliary gas.  More than one auxiliary gas port may be provided.  The metal halide enters axially through port 22. The burning fuel and auxiliary gas spiral round the halide stream and are preferably out of phase one with the other.  Various additives may be added to the reaction space, e.g. metal chloride, white metal oxides, chlorine, water or aromatic organic compounds.

Abstract: 686,369. Thermionic valve gating circuits. SHORT BROS. & HARLAND, Ltd. Sept. 27, 1951, No. 22582/51. Class 40 (vi). [Also in Group XL (b)] Thermionic valve gating circuits 1, 3, 5 ... (2n-1) employed in a distributer (see Group XL (b)) each comprise two sections a, b, the first of which is normally conducting and cuts off the second over the cathode resistor R7. The input voltages from terminals I are applied to the suppressor grids and the output is applied to terminal O from across the common anode resistor R8. The gates are opened in succession by switching pulses generated by a chain of trigger stages 2, 4, 6 ... 2n. On receipt of a switching pulse, Fig. 3, the grid of the a section is driven negative allowing the b section to conduct at level A. The a section cuts off at level B. The effective part of the switching pulse is accordingly restricted to between levels A and B and avoids the curved portions of the pulse. The switching pulses do not have perfectly vertical sides and a variable resistance R10 is employed to control the current taken by the a sections and hence the level at which a switching pulse is effective. By this means it is possible to control the degree of over- or under-lapping between the operation of adjacent gates. A high value of cathode resistance R7 is employed to introduce feed-back to stabilize the anode current of the b section. The Specification discusses the choice of bias for the control and suppressor grids to sustain this condition. Specification 660,270 is referred to.

Title: Improvements in optical devices for the examination of axial directions and the like
Filed: 1933-08-14
Abstract: 424,004. Optical apparatus. ZEISS, C., [Firm of], Carl - Zeiss- Strasse, Jena, Germany. Aug. 14, 1933, No. 22610. Convention date, Aug. 20, 1932. [Class 97 (i)] Apparatus for testing the coincidence of two axial directions, or the evenness of a surface, &c. consists of two interconnected optical systems producing images of the same magnification for any object plane at rightangles to the principal axis of the combined system, the two images of the principal axis being parallel and in the same direction, the images of one or both of the axes at right angles to the principal axis and lying in the object plane extending in opposite directions, and the two images being coplanar for any object plane. Fig. 1 shows a system in which one of the images is completely inverted relatively to the other. One imageforming system consists of a block comprising two right-angled prisms 1, 2 with a semi-reflecting separating surface, and a similar block 3, 4, these blocks acting as a pair of parallel plates as regards transmitted light. The second system consists of the prisms 1, 4, acting as reflectors, together with reflecting prisms 5, 6 and lenses 7, 8 of equal focal lengths having a common focal point F2 so that they act as a reversing telescope of unit magnification. The front focus F1 of the lens 7 is imaged by the second system at the rear focus F'2 of the lens 8, and the arrangement is such that the image of F'2 formed by reflection at the separating surface of the prisms 3, 4 lies at the same point F<x>1 as the image of F1 formed by the first system. The principal axis Z-Z forms a sighting line. Figs. 3 to 5 shows a form consisting of reflectors only. Light incident in the direction O on a prism 15 is partly transmitted by the semi-reflecting surface 16, the transmitted light undergoing one reflection by a prism 17 and two reflections by a prism 18 so as to be incident on the semi-reflecting surface 20 of a prism 19, the light reflected by the surface 20 emerging in the direction O1 parallel to O. Light reflected by the surface 16 undergoes two reflections by a prism 21 and a single reflection by a prism 22 so as to be partly transmitted by the surface 20 in the direction O1. Fig. 14 shows a device 48 in accordance with the invention (as in Figs. 3 to 5) in conjunction with an objective forming a complete sighting system. The objective comprises a telescope of Galilean type having a converging system 46 and a diverging system 47, and the device 48 is situated between the two parts of the objective. The images are viewed by a microscope 51, 52 having a focusing device 54. The device can also be used for determining one co-ordinate of a slide displaceable according to two co-ordinates, i.e. for reading a scale marked on the slide and extending at right-angles to the sighting line provided by the system, the slide being displaceable in the direction of the scale and also along the direction of the sighting line.

Abstract: 1,076,917. Packaging-machines; endless conveyers. CONSOLIDATED CIGAR CORPORATION. May 20, 1966, No. 22617/66. Headings B8A and B8C. Apparatus for loading articles, e.g. cigers, into cases comprises a feed conveyer 21 feeding the cigars into a case T which is supported in a frame 48 pivotable about an axis 52 to allow the case to swing counterclockwise when a cigar is raised by stopping of those in front of it and the pressure of those behind, thus raising a sensing plate 90. The cigars fall down a shoot 26 on to a plate (40), Figs. 4 and 5 (not shown), which tilts under the weight of the cigar resulting in the arm (44) pushing the upper end of the cigars sideways to align the cigars transversely on the conveyer 21. The conveyer 21 feeds the cigars on to a bridge plate 24 where they are pushed into the case by the succeeding cigars. When a cigar rises as described above, the plate 90 pivots about an axis 92 until its free end 94 activates a switch S2 to energize a solenoid 80. This retracts a plunger 81 causing a pawl (72), Fig. 8 (not shown), to be withdrawn from the teeth (58) of the rack 56 pivotally connected to the frame 48. Simultaneously a pawl (67) is raised to limit the rack movement to one tooth. The raising of the pawl (67) opens a switch (S1) to de-energize the solenoid 80 so that the pawls (67), (72) return to their initial positions. This procedure is continued until the plate 90 returns to its normal position. The process is repeated until the case is horizontal and full whereon the frame 48 activates a switch to de-energize the belt 21.

Aug. 15, 1933, No. 22742. Convention date, Aug. 25, 1932. [Class 78 (ii).] Electric plant.-A lift control system oomprises a plurality of devices for controlling the circuits in the system, a switch common to all said devices, means responsive to cage position for causing an operation of the switch when the cage reaches each of a plurality of predetermined points in the shaft, means including circuit connections responsive to the operation of the switch at predetermined points for sequentially operating said devices, and means responsive to upward travel of the cage for causing a sequential operation to occur in one order, and means responsive to downward travel of the cage for causing the sequential operation to occur in another order. The shaft is divided into a number of zones Z1 .. Z4 corresponding to the floors, and the arrangement is such that one only of the selecting relays sl .. s4 is energized while the cage is in a particular zone ; the relay s1 being energized while the cage is in the zone Z1, and so on. The transfer from one relay to another when the cage arrives at the junction of adjacent zones is initiated by the action of magnetizable plates NI<1> situated at these points on the notching relay N1 on the cage C. The energization of the relays for the intermediate floors is controlled by the notching relay N1, impulse relay 10, closing relay 11, opening relay 12, and the directional switches 1, 2, but additional energizing circuits controlled by resetting relays 13, 14 are provided for the relays associated with the terminal floors. The relays 13, 14 are closed by limit switches DL, UL actuated by a cam 15 on the cage. The selecting relays associated with even numbered floors are energized in response to energization of relay 11, and the relays associated with odd numbered floors are energized in response to the de-energization of that relay. Only one selecting relay at a time is controlled by opening-relay 12, and consequently the pair of relays 11, 12 is effective to control the sequential energization and deenergization of any desired number of selecting relays. The closure of certain contact members by the actuation of the selecting relays causes the illumination of floor position indicating lamps.
