IPC: F16P3/06
Filed: 1924-10-29
Abstract: 238,415. Broughton, J. Oct. 29, 1924. Guards, controlling.-In power presses and other machines having a reciprocating tool &c., a guard is pivoted to a sliding shutter or other member adapted to be moved in front of the working space and is automatically swung outwardly from the working space before completion of the descent of the plunger &c., so sweeping the operative's hand from the danger zone. A sliding shutter 2, supported at its upper or lower edge, or at each edge, by a guide rail 3, is moved by a link 14 and lever 11 operated, for instance, by a slotted plate on the press plunger, and has hinged to it a curved guard plate 1. The plate 1 lies substantially at right-angles to the shutter 2 when this member is retracted, but is swung outwardly, as shown in Fig. 3, during movement of the shutter by the cranked end 10 of the hinge pin 7, which is connected by a telescopic spring link 17 to a ball joint on the lever 11. The motion of the plate 1 is preferably completed before full travel of the shutter 2, the subsequent motion of which extends the link 17, as shown. In a modification, Fig. 6, the plate 1 is turned. against the action of a spring 26, by the contact with a fixed collar 28 on the rail 3 of a loose sleeve 27 connected to the crank 10 by a telescopic link 17. If the shutter 2 is arrested at the completion of the swing of the plate 1, the link 17 may be rigid. The shutter 2 may be replaced by a vertical rod. According to the Provisional Specification, the sleeve 27 is connected by a cranked link to the crank 10, which is an extension of one hinge-eye of the pivoted guard; the guard may sweep between the upper and lower press tools; and the sliding shutter &c. may be actuated by any moving part of the press.

Title: Process for the manufacture of biaxially stretched sealable polypropylene films
IPC: B29C35/08
Filed: 1965-06-18
Abstract: 1,040,388. Films. KALLE A.G. June 18, 1965 [June 20, 1964], No. 25970/65. Heading B5B. In a process for the manufacture of biaxially stretched sealable polypropylene film, an unstretched polypropylene film is heated to its softening point, quenched and exposed for two to fifteen seconds, at temperatures between 130‹ and 160‹ C., to an energetic radiation in a chlorine atmosphere, cooled or quenched and biaxially stretched. The heated film may be quenched with ice-water. Ultra violet radiation is preferred but alternatively there may be used gamma rays, electron beams or silent electric discharges (corona or glow discharges). The irradiation and application of the chlorine need not necessarily take place on the same side of the film. The softened polypropylene film is sufficiently permeable to radiation so that it is possible for example to contact one side of the film with chlorine, while irradiation is carried out on the other side of the film. Heating of chlorine and film to the reaction temperature can be performed separately or together in the reaction zone. Films so made are capable of being heat sealed in a temperature range in which no appreciable heat shrinkage occurs in the sealing area.

Title: Reader-Decoder For Tape-Operated Type Composing Machines
IPC: B41B27/00
Filed: 1966-06-10
Abstract: 1,154,421. Type - composing machines. HARRIS-INTERTYPE CORP. 10 June, 1966 [11 June, 1965; 9 Nov., 1965], No. 26066/66. Heading B6W. A tape reading and decoding control apparatus for type-composing machines comprises a reader 10, a decoder 15, tape drive means in the reader to move tape 12 stepwise through the reader, a tape drive speed control circuit including a connection for feeding stepping signals to control the drive means and advance the tape at a normal predetermined speed and a plurality of recognition circuits in the decoder responsive to certain predetermined code words, the tape drive speed control circuit including a control connection to the tape drive arranged automatically to delay the advancement of the tape to the reader relative to the normal rate in response to reading some of the predetermined code words and to accelerate the advancement of the tape in response to reading others of the predetermined code words. Decoder 15 provides a seven-line output to the " B " register where the decoded signal from tape 12 is first set up. The signal in the " B " register is transferred to the " A " register and then to solenoids 40 under the control of shift gates 30 and 35. Solenoids 40 actuate mechanical decoding strips 50. The drive means normally advances the tape stepwise through the reader in response to stepping signals supplied from the control circuit. These signals normally occur at a rate corresponding to the functioning of the machine, e.g. they may be supplied as pulses from photocell 62 which is actuated by light from lamp 60 shining through slit 66 in rotating disc 65 which disc is driven in time with the operating cycle of the machine (e.g. the matrix escapement mechanism). A high speed pulse generator supplies stepping pulses to the reader at a substantially greater rate than the normal timing pulses whenever a tape feed code word or an erase code signal is received in the decoder thus advancing such code signals through the reader at an accelerated rate. A pulse sink is arranged to receive stepping pulses selectively from the reading speed control circuit thus diverting a number of stepping signals (according to the delay required) from the tape drive causing a corresponding delay in the advancement of the reader to the next code word. The sink is actuated whenever code signals which cause operations requiring more than one operating cycle of the machine to complete, are received in the decoder. A reversing control on the tape reader may be provided and the recognition circuits may include a circuit arranged to stop the reader on a predetermined code word (e.g. an end of line code). During reverse reading the machine is not operated by the decoder.

Filed: 1930-09-01
Abstract: 366,510. Treating sewage ; filters ; filtering-media. MARS, J. C., 225, West 12th Street, New York, U.S.A. Sept. 1, 1930, No. 26081. Convention date, Oct. 22, 1929. [Classes 46 and 111.] Sewage sludge is deposited on a carrier consisting of pieces of refractory material, drying gases are passed over the deposited material and the dried matter is heated to effect thermal decomposition. The refractory material may be coke, screened ashes, broken brick, wood charcoal, or sandstone and the pieces should have a rough surface and be of such a size as to allow free flow through the interstices. It may be used again after the heat treatment. Sewage is passed successively through a series of coke filters 23, Fig. 3, and a similar filter 24 fitted with a coil 30 by means of which the liquid is subjected for sterilization to a highfrequency or other electric discharge. In each filter the sewage is passed downward behind a baffle 26, Fig. 1, and rises through the coke for discharge at the surface to the next filter. The coke is continuously supplied to the top of each bed and removed from the bottom by an endless band 11 arranged in a casing 12 behind the baffle 26. The upper end of the casing 12 turns downward and delivers the coke with the sludge admixed therewith below the surface of liquid in a tank 13, where the sludge is subjected to an anµrobic digestion. Comminuted garbage from a disintegrator 14 may be delivered to the tank with the coke and sludge. The solid matter is removed from the bottom of the tank by a conveyer 60, Fig. 2, in a casing 15, and liquid rises through filtering material 33 behind a baffle 47 and is discharged through an adjustable outlet 43. Gas and grease rising to the surface are collected in compartments formed by baffles 35 and pass outward through sealing troughs 39 to a compartment 37, which has outlets 41, 40 for the gas and grease respectively. Heating coils 51 are provided near the bottom of the tank. The solid matter is discharged by the conveyer 60 into a dehydrating device 16, Fig. 4, provided with downwardly inclined screens 52 and screws 57, which move the material to an outlet valve 53. Pipes 54, 55, 56 are provided respectively for the outlet of separated liquid, the supply of hot gas from a retort 17 for drying, and for the outlet of gas. The coke &c. passes through the valve 53 into a retort 17 and is subjected to distillation which drives off combustible gas and leaves a residue, part of which may be delivered through a screen 19 and by a conveyer 20 to the filters 23 and part by a conveyer 21 to a gas-producer or water gas generator 22.

Abstract: 1,146,642. Fluid filter. J. MULLER. 13 June, 1966 [11 June, 1965], No. 26152/66. Headings BID and BIT. A filter for gas or liquid comprises a series of hollow edge filter elements 6 arranged in a circle and a hollow arm 11 rotatable to engage their inlet ports in succession, thereby permitting reverse flow through successive elements 6 to discharge line 16, the arm 11 being rotated by a hydraulic or pneumatic motor 20 driven by the incoming fluid to be filtered. Fluid enters at 23, passes through motor 20, down a nozzle 24 and upwards through preliminary metal cloth filter 25 to elements 6, which are enclosed in separate jackets 8. Motor 20 rotates arm 11 in steps through gears 21 and Maltese cross 22, and in Fig. 1 reverse flow through the element 6 aligned with arm 11 is caused by the outlet pressure of the filtrate in chamber 9. In Figs. 3-8, not shown, hollow arms on a common shaft engage both ends of successive elements, and reverse flow fluid is forced through the element by movement of a piston in a central cylinder. The upper side of the cylinder is filled with filtered fluid as the piston falls, with the arms stopped between two elements, and this fluid is forced through the next element as arm movement opens a port exposing the lower side of the piston to unfiltered fluid. The double piston of Fig. 8 permits a reverse flow pressure exceeding the supply pressure to be generated.
