Abstract: 821,049. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Dec. 1, 1955 [Dec. 1, 1954], No. 34429/55. Class 138(1). The driving drum of a cable-operated windscreen wiper includes a cable supporting member movable outwardly relatively to the drum so as to increase the tension in a cable wrapped on the drum, a resilient member urging the supporting member outwardly and means for locking the supporting member relatively to the drum. As shown in Figs. 2 and 4, the drum 10 is in the form of a pulley 11 having four peripheral cable receiving grooves and is mounted a shift 9 driven by a conventional motor so as to operate a pair of wipers by cables 22, 23. The drum 11 is provided in one end with a pair of chordal slots 12, 13 to respectively receive cable supporting members 16, 17 in the form of plates having claws 18, 19. The members 16, 17 are urged outwardly of the periphery of the drum by springs 20, 21 housed in circular bores 14, 15, Fig. 3, which intersect the slots 12, 13. The cable 22 is anchored at 221 to the claw 18 and passes around the drum and then out tangentially to one wiper rockshaft from which it returns to the drum and is anchored to a fixed claw 25 on the drum. Similarly the cable 23 is anchored at 23<SP>1</SP> to the claw 19 from which it passes round the drum to the other wiper rockshaft and returns to the drum where it is anchored to another fixed claw 24 on the drum. The members 16, 17 are locked in position by a pressure plate 27 dampable by a wing nut 26. The plate has an inturned end 28 and a tongue 29 which engages a slot in the drum. When the nut 26 is loosened the springs 20, 21 tension the cables 22, 23 by moving the claws 18, 19 outwardly of the drum. The nut is then tightened to prevent the cables when operating, from moving the members 16, 17 inwardly of the drum against their springs. When the nut 26 is loosened outward movement of the members 16, 17 is limited by shoulders 30, 31 therein, engaging the end 28 of the plate 27. A single large spring in an enlarged chamber overlying the members 16, 17 may be used instead of the two springs 20, 21. Moreover the claws 18, 19 may be reversely arranged and the cable anchors 221, 231 may be fixed to the drum periphery and adjacent cable portions may then be slidable through the claws 18, 19. Furthermore the slots 12, 13 may be radial and the members 16, 17 may be pivoted to the periphery of the drum so as to be swung outwardly by springs.

Title: An improved method of drying material and a conveyor mechanism used in connection with same
IPC: C11D13/26
Filed: 1934-11-30
Abstract: 448,123. Drying extruded material. SWIFT & CO., Union Stock Yards, Chicago, U.S.A.-(Assignees of Walter, C. T.) Nov. 30, 1934, No. 34502. Convention date, Dec. 21, 1933. [Class 34 (ii)] [See also Groups V, XXIV, and XXX] A method of laying out extruded material to be dried consists in laying out simultaneously a transverse series of string-like lengths of the material, each in a zigzag path on a moving conveyer substantially lengthwise thereof. In the construction shown in Figs. 1 and 3, a carriage 1, adapted to be reciprocated on racks 3, is provided with extrusion dies 12 which receive soap in plastic form pumped through pipes connected by unversal joints and communicating with a source of supply of soap. The carriage is connected by a link 31 and a swivel joint 32 to an endless chain 28 which is driven by an electric motor, and travels at a faster rate than that of an endless conveyer 10. Spring buffers 29, 30 absorb the energy of the carriage during its reversal of direction. The rails 3 are given lateral movement on rails 8 by means of cams 39, 40, which are driven by a motor 36 and are connected to rigid members 41, 42. The soap extruded from the dies 12 falls on the conveyer 10 in zigzag strings or tubes 26, as shown in' Fig. 2. The link 31 as shown in Fig. 9 comprises two enclosed coil springs 102, 105 bearing against collars between which is a slidable piston 100, the spring 102 resisting tension and the spring 105 resisting compression. In the construction shown in Fig. 4, the rail assembly for the carriage 1 has no independent lateral movement, but is inclined slightly in the direction of motion of the conveyer belt so that the strings of soap are laid on the conveyer 10 in the form shown in Fig. 5. An extrusion die is shown in Fig. 7. Plastic soap enters under pressure through a pipe 53 and passes to an outlet 63 through a conical passage 64 formed by a detachable plate 56 and a spindle 45. The spindle is driven by gearing in a chamber 71 containing oil 75, which is prevented by a shield 85 from entering a hole 65 extending the length of the spindle. Air under pressure enters the chamber 71 through a pipe 76 and as it passes out through the hole 65 assists in the extrusion of soap in tubular form.

Abstract: 1515856 Cutting webs MITA INDUSTRIAL CO Ltd 22 Aug 1975 [23 Aug 1974] 34980/75 Heading B8R To prevent jamming of a cutter 11, Fig. 8 in a copying machine, the end of a copy paper web is retracted from the cutting position after a cutting operation. The web is fed from a reel by intermittently driven rollers 8, 8<SP>1</SP> past a rotary blade 9 and fixed blade 10 to rollers 19, 19<SP>1</SP> which feed sheets to processing stations. In Fig. 8, when rollers 8, 8<SP>1</SP> are idling just before the cutting operation, the tension in the web driven by rollers 19, 19<SP>1</SP> lifts a plate 65 resting on the web surface. After cutting, the tension disappears, the plate 65 drops and the cut web end is retracted. In an alternative form, Fig. 4, a solenoid 48 pivots a gear segment 47 into reverse driving engagement with a spur gear 45 associated with roller 8 thus retracting the web. At the initiation of a machine cycle, roller 8 feeds the web until its leading edge actuates a switch (S1), Fig. 2 (not shown). An original document (a) is placed on a reciprocable frame (3) and the document and web fed forwards. When a projection (38) on the frame (3) is sensed by a switch (S3), the cutter is operated.

Abstract: 1,123,537. Magnetic storage matrices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 31 July, 1967 [3 Aug., 1966], No. 35008/67. Heading H3B. A 3-dimensional word organized magnetic data store comprises a plurality of stacked plates G having storage elements C formed therein, storage elements belonging to the same word being coupled by printed circuit word conductors K extending through the storage elements to a common magnetic switching element S arranged on the same plate G, together with a plurality of storage and switching elements of other words, the switching elements being arranged in a matrix of rows and columns with row conductors X for the switching elements being formed as printed circuit conductors on the plates and column conductors Y being formed as coils surrounding the switching elements of a column. The switching elements are biased to saturation in a given direction by means of an additional coil (not shown) embracing all the switching elements, by means of a permanent magnet or by supplying the X or Y conductors with D.C. Each storage element C is threaded by a sense-control conductor Z. To read a word, half-select currents are supplied to selected conductors X, Y so that the selected switching element is driven away from its initial saturated state. A current pulse is thereby induced in the corresponding word conductor K sufficient to drive all storage elements in the selected word to the "0" state, generating output pulses in the Z-conductors. When the X, Y currents are terminated the selected switching element returns to its initial state due to the bias field, generating a reverse pulse in the word conductor tending to write a "1" in all storage elements of the word. An inhibit pulse is applied simultaneously to those Z-conductors corresponding to storage elements in which a "0" is to be written. A modified switching element is described in which a longi. tudinal slot is formed in each element, windings K and X extending helically up one side of the element and with opposite winding sense down the other side. The turns of the two windings are interleaved.

Abstract: 476,208. Depositing metals by electric discharge; high vacua. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Dec. 24, 1936, No. 35369. Convention date, Dec. 28, 1935. [Class 41] . [Also in Group XXVIII] In the method of metallizing articles by cathode disintegration by a glow discharge at a pressure below 0À2 mm. a magnetic field, which may be of strength about 300 gauss, is provided whereby the electrons are caused to follow a path between cathode and anode which is materially longer than the direct path along the electric lines of force; by this means the current for a given gas pressure is increased and the ignition voltage reduced. The arrangement is also of use when the discharge is employed for the purpose of reducing the gas pressure in a vessel. The angle between the magnetic and electric fields is preferably greater than 45‹ and is preferably about 90‹ in at least one part of the discharge space. In an arrangement for coating a cylinder 12, Fig. 3, the cathode 4 consists of an axially arranged rod of the coating metal, e.g. tungsten or silver, passing normally through anode plates 5, 6. A magnetic field parallel to the cathode imposes a circular component on the electron movement. In the apparatus shown in Fig. 5, the anode consists of a cylinder 8 to be coated and the cathode of end plates 9, 10 which may be of different metals of which a mixture is to be deposited. The magnetic field is axial. The cylinder 8 may be shorter than shown or may be replaced by an annular wire. For reduction of gas pressure an arrangement comprising a cylindrical anode and an axial rod-shaped cathode may be employed with an axial magnetic field.
