IPC: C23C4/18
Filed: 1952-03-17
Abstract: 750,215. Coating with metals. BRENNAN, R. M. March 17, 1952, No. 6845/52. Class 82(2). Metal strip is continuously produced by spraying metal onto a moving band so that an even layer is deposited. Metal, such as nickel, is sprayed from a nozzle 11 onto a stainless steel band 8 passing spirally round two drums 7 rotated by a variable-speed motor 1. The strip 9 so formed is coiled off onto a drum 10 also driven by the motor 1 through a slipping- clutch 3. The band passes through a scraping, cleaning, anodizing or lubricating chamber 13 before being presented to the nozzle 11. The drum shaft 12 may have a cooling passage. In a modification, the band is not continuous and the strip is built up on the three turns round a drum 32 as shown in Fig. 5. In a further modification, the band does not pass spirally round the drums but is of wide section and five sprays are used. The band may be composed of several adjacent narrow bands and the strip taken off as a full-width strip or as several narrow strips. Slitting tools may be provided to assist in taking off narrow strips. The thickness of strip may be controlled by banks of sprays or by varying the speed of the band. The sprays may be as described in Specification 735,695. The density and porosity of the strip may be controlled by controlling the atmospheric temperatures and constituency. Laminated metal may be produced and the strip may be subsequently rolled or heat treated. Different metals may be sprayed simultaneously to produce alloy strips. Stripping may be assisted by a parting knife. Specification 680,988 [Group XXII] also is referred to. Reference has been directed by the Comptroller to Specification 735,695.

Title: Improvements in or relating to latch mechanisms
IPC: E05B65/32
Filed: 1948-03-05
Abstract: 644,646. Locks. HOUDAILLE-HERSHEY CORPORATION. March 5, 1948, No. 6895. Convention date, April 25, 1947. [Class 44] Door latch mechanism, particularly for vehicle doors, comprises a keeper, a movably mounted bolt arranged to engage the keeper, and means for holding the bolt in any of a number of door holding positions, the said means including a manually controllable release member operatively disconnected from the remainder of the retaining means when the bolt is disengaged from the keeper, the release member being operable to release the retaining means when the bolt and keeper are engaged to latch the door. In the form shown, a two-armed rotary bolt A is mounted on a pin 12 in a housing 16 secured to plate 10 of the casing, and co-operates with a keeper 30, Fig. 3, having a channel the upper wall of which has a downward projection. The take-up mechanism for holding the door in a number of latched positions includes an arm 19, Figs. 1 and 2, pivoted at 20, and a take-up arm 22 pivoted at its lower end on a pin 23 on the latching arm 14 of the bolt A, and biassed by a spring 26 which tends to rotate it counter-clockwise as seen in Fig. 1. In the unlatched position, Fig. 1, a projection 28 on the take-up arm 22 engages a collar 29 on an inward extension of the pin 12 and prevents further rotation, but as the bolt A is rotated on entering the keeper, the arm 22 is lifted so that it is further rotated by the spring 26. A lug 33 at the upper end of the take up arm then slides up surfaces 32 of the arm 19 and finally engages serrations 34, holding the bolt against unlatching. The outside release mechanism includes a sliding plate 36 guided by stamped up parts 40, 41, of the plate 11, and by pin and slot engagement with the pin 20, spring biassed to the position of Fig. 1, and actuated by a push-button, or by a handle, engaging a flange 37. In normal position, a flange 39 on the plate 36 supports the nose 48 at the inner end of the arm 19, but on the plate being pressed inwardly, the nose 48 is released, and arm 19 drops, releasing the bolt for free rotation. Arm 19 is afterwards lifted by contact of a pin 49 on arm 22 with the curved under side of arm 19. Release from inside is effected by a release plate 53, Fig. 7, pivoted at 51 on plate 11 and actuated by a link 56 from a handle. The plate 53 has a lug 62 which makes contact with a flange 60, Fig. 1, on the sliding plate 36 and moves the latter on operation of the inside handle. Locking against operation from outside is effected by a locking plate 63, Fig. 6, which can be controlled by the spindle 68 of a key lock, and also by a push rod 69, a flange 66 on plate 63 being positioned to obstruct movement of the release plate 36, Fig. 1. The inside release plate 53 is arranged to move the locking plate 63 to unlocking position on operation to unlock.

Filed: 1965-02-18
Abstract: 1,095,134. Magnetic recording media. GENERAL ELECTRIC CO. Feb. 18, 1965 [March 26, 1964], No. 7017/65. Heading H1H. Magnetic particles of single domain size and comprising Fe/Co alloy cores coated with Fe/Co ferrimagnetic spinel oxide substantially as described in Specification 996,913, are used in the manufacture of magnetic recording media. The alloy particles are prepared by electrodeposition into mercury as described in Specification 815,919. After deposition the particles are heat-aged in the mercury from 1 to 70 hours at 200 to 300 C. This first removes dendritic branches and then increases coercivity. Round or acicular particles may be produced depending on the state of quiencence of the Hg surface on deposition. After ageing the particles are oxidized by moist air or by a chemical agent. Residual Hg is removed by vacuum distillation, or by flotation. The particles which contain 1-15% of oxygen, are dried, milled to break up agglomerates, dispersed in a binder, applied to a support, aligned by a magnetic field and dried to form a magnetic recording medium. The cobalt to iron ratio may lie between 10-90 and 80-20. The magnetic recording medium may be a tape, disc drum, or transfer tape.

Title: Improvements in and relating to the manufacture of bread
IPC: A21C5/00
Filed: 1941-06-04
Abstract: 549,854. Bread-making. HARBER, L. S., POINTON, J. E., and BAKER PERKINS, Ltd. June 4, 1941, No. 7079. [Class 87 (ii)] [Also in Group VI] In the manufacture of laminated bread, dough pieces are fed in parallel to a corresponding number of flattening rolls or bands to form plaques with the adjacent flattened faces disposed towards one another. In the machine shown in Figs. 1 and 2, dough pieces are fed from hoppers 47 between ground or ribbed rollers 1 and fixed elements 2 having a concave face 3 terminating in a neck-forming blade 5 so that each piece is shaped to form two lobes connected by a neck, the lobes being unsupported except at the neck. The pieces then pass between rotary discs 6 and a common supporting tray 7 to discs 8, or knives, which sever the necks. The lobes, aided by a rotary spindle 27, are delivered to pairs of adjustable rolls 19, which form them into plaques. A second set of rolls having less nip may be arranged beneath the rolls 19. The plaques are discharged through shoots, formed by converging partitions 29, 30 into the baking tin 31. The shafts 12, 13 of the rollers 1 and discs 6 are driven from the main shaft 14 by a chain 16 and sprockets and the rolls 19 by spiral gears 21, 22 from a shaft 23 driven by a chain 25 and sprockets. A cam shaft 41 carries a cam 46 operating the two-part pivoted hoppers 47 against return springs 57, a cam 40 controlling a lever 37 for raising the inner partitions 30 of the shoot against a return spring 36 out of the tin 31 after delivery of the plaques thereto to permit the tin to be moved by a chain conveyer 32 and a cam 42 controlling a pivoted stop 43 for the tins. The partitions 30 terminate in depending fingers or wires to prevent adhesion of the dough during withdrawal of the partitions. The plaques may be collected for simultaneous delivery into the tin by means of a pair of rotatable or oscillatable flaps comprising oiling means (60, 61, Fig. 6, not shown), constructed as described in Specification 546,429. The stop 43 for the tins may be dispensed with, the time of arrival of the tins being synchronized with the operation of the flaps or an intermittently-operated conveyer being employed. In modifications, the rolls are arranged in two parallel rows, horizontal or inclined, so that the plaques from one row alternate with those from the other row and the plaques are delivered through a vertically-partitioned shoot (70, 72a, Figs. 7 and 9, not shown) to the flaps or through a further vertically movable chute with vertical, parallel partitions directly to the tin. In the machine shown in Fig. 10, a single dough piece is delivered by a shoot 74 to a conveyer surface 75 supported by a table 76 and is elongated in passing under a triangular board 77 and then fed between rotary discs 78 and fixed blades 79 to form a row of pieces connected by short necks which are gradually reduced and finally severed. Specifications 400,619, [Group VI), 420,524, and 541,757 also are referred to.
