Title: Sputtering apparatus and method
Inventor: KUMAGAI HENRY YASUO
IPC: H01J37/34
Filed: 1969-05-30
Abstract: 1275428 Sputtering apparatus WESTERN ELECTRIC CO Inc 30 May 1969 [31 May 1968] 27428/69 Heading C7F A sputtering apparatus comprises a plurality of pairs of adjacent electrodes each made from or including the material to be sputtered, means for applying A.C. between adjacent electrodes to establish an oscillating field and provide an electron path between each pair of electrodes, means for supporting the substrate so as to be outside said electron path, a conductive screen, and means to apply a bias potential thereto, said screen being positioned to distort said field and increase the rate of coating of the substrate. In Fig. 1, substrates 32 move horizontally past elements 37a to 37f in an argon atmosphere, the elements being hollow for transmission of coolant therethrough, and alternate elements 37a, c and e, and 37b, d and f, respectively are connected in common to opposite terminals of an A. C. source so that whilst 3 elements act as cathodes and are sputtered the others act as anodes and attract electrons which would otherwise cause undesirable heating of the substrate. The cathode current and sputtering rate is increased by applying a + ve or -ve D.C. bias to a conducting plate 51 attached to chamber wall 24 by insulator 52. For sputtering alloys, alternate rods 37 may be of the different metals of the alloy, a D.C. bias being superimposed on one side of the A.C. source to cause one component of the alloy to sputter at a higher rate. Fig. 9 shows an alternative arrangement wherein substrate wire 59 is subjected to a magnetic field by pulsed D.C. source 68, the targets being parallel wires 61a to 61h as shown and 67 being the biased plate. Substrates mentioned are glass, Cu-Be, and Cu; coatings may be Al, Ta/Si, permalloy, SiO 2  (for which RF is used), and Al containing Ta or Ti which is sputtered from Al rods wound with a spiral of Ta or Ti, Fig. 4 (not shown).

Title: Variable ratio and/or reversing gearing
Inventor: EHRLICH JOSEF
IPC: B63H23/08
Filed: 1961-07-28
Abstract: 938,303. Positive clutches; change speed gearing; reversing gearing. DE HAVILLAND ENGINE CO. Ltd. July 16, 1962 [July 28, 1961; Aug. 29, 1961], Nos. 27506/61 and 31121/61. Class 80 (2). [Also in Group XXXIII] In a change-speed or reversing gearing selective engagement of either of two gears is effected by a double dog clutch axially slidable on a common shaft, having limited axial movement, to frictionally engage the gears, a spring-loaded connection preventing axial movement of the dog clutch member on the common shaft until a predetermined axial force is applied. In a reversing gear for an outboard motor unit, a bevel gear 10 drives two bevel gears 6, 7 freely rotatable on a propeller shaft 2 having limited axial freedom, the two gears 6, 7 being formed on their facing sides with dog clutch teeth 16A, 16B and conical friction clutch surfaces 17A, 17B. Rigid with the shaft 2 are two corresponding friction clutch surfaces 19A, 19B respectively engageable with the gear surfaces on axial movement of the shaft. A double dog clutch member 12 is drivingly connected to the shaft 2 and is axially restrained to the shaft by a spring-loaded ball 13. A selector fork 20 moves the clutch member 12 axially towards one or other of the gears, initially moving the shaft 2 to engage the appropriate friction clutch, until the axial force is sufficient to overcome the ball detent 13 and allow synchronous engagement of the relevant dog clutch. The invention may also be applied to changespeed gearing in which spur gears engaged by further spur gears on a countershaft replace the bevel reverse gears.

Title: Proof Press
IPC: B41F3/20
Filed: 1968-06-14
Abstract: 1,190,896. Printing apparatus. SCHNEIDER & CO., A.G. 14 June, 1968 [16 June, 1967], No. 28303/68. Heading B6C. In a cylinder proofing press linked vertical movement into and out of their operating positions of inking apparatus and an impression cylinder is brought about by interaction of a vertically movable slide, mounted in a carriage bearing the inking apparatus and impression cylinder, with elements at the ends of a table over which the carriage moves. Table I has side rails 3, 4 and an upper surface on which a printing plate may be mounted. The side rails 3, 4 support racks 45, on which pinions 44 run, and have lateral grooves in which run carriage-supporting wheels 7. A vertical slide 16 in a side plate 6 of the carriage is movable when a roller 20 on it abuts on an inclined surface 21 at an end of the table 1. The slide 16 is connected to movable blocks 11 in both side plates 5, 6 of the carriage, and causes the impression cylinder 9 to be raised or lowered. It is also connected to the inking apparatus 8, and causes it to be raised and lowered. In use the carriage is moved over a plate on table 1, and the inking apparatus inks it. At the end of the table 1 roller 20 contacts an inclined surface, the inking apparatus rises and the impression cylinder 9 descends. On a return stroke a sheet of paper laid on the plate is printed on. Overdead-centre mechanisms in the linkages to the inking apparatus and impression cylinder hold them in their extreme positions until they are moved again by slide 16. The pinions 44 may be electrically driven to move the carriage. One of the inclined surfaces at the ends of the table 1 is upwards-facing and the other downwards-facing. One of them may be pivot-mounted, and movable to an inoperative position, and microswitches operated by a shoe 49 on the carriage may be made to stop or reverse the direction of movement of the carriage either at or before the full extent of its travel, as determined by the operator. Several inking strokes may be followed by stopping of the machine and raising of the inking apparatus in preparation for a printing stroke.

Title: Improvements relating to electro-magnetically actuated devices for controlling electric circuits
IPC: H02J7/22
Filed: 1935-10-15
Abstract: 464,336. Electromagnetic switches and interrupters. LUCAS, Ltd., J., and LAIRD, J. A. Oct. 15, 1935, Nos. 28418 and 33462. [Class 38 (v)] In order to compensate for displacement of the contacts of an electromagnetic device such as a voltage regulator, cut-out &c. due to wear, temperature or other condition the relatively fixed contact is carried by a member adapted to be actuated by a spring and held stationary under electromagnetic action when the device is energized, the arrangement being such that when the electromagnetic action is interrupted the spring can move the said member in the direction for bringing its contact or contacts to the desired position relatively to the other contact or contacts. As shown in Fig. 1, the relatively fixed contact e of a voltage regulator is normally held against the movable contact c carried on the spring-mounted armature b by a spring i acting on a slidable bracket f of magnetic material by which the contact e is carried. This member is arranged to form a part of the magnetic circuit of the operating electromagnet o so that when the latter is energized the attraction of the member to the adjacent magnetic member g holds this member in position against the pull of the spring i. Thus as the armature is attracted the contact c can be drawn away from the contact e. On de-energization of the operating magnet, however, the contacts are held together by the spring i and any displacement of the fixed contact which otherwise would have occurred due to wear, variation of temperature or other condition is effectively compensated for. The retractive force acting on the armature may be adjusted by adjustment of a screw n bearing on a blade spring m attached to the armature. In a modified arrangement described the attraction of the armature of an automatic cut-out combined with the regulator holds the member carrying the relatively fixed contact of the cutout against the spring i during the movements of the regulator armature, Figs. 3 and 4 (not shown).

A needle thread-wiping device for a sewing machine comprises a guide tube having a predetermined lengthwise configuration, an elongated resilient thread-wiping finger shiftably supported in said guide tube and having a portion movable to project from said guide tube, said thread-wiping finger having a normal lengthwise configuration differing from the lengthwise configuration of said tube, and a thread-engaging means on said portion of said thread-wiping finger. A plate 23, secured by bolts 21 to the rear face of a sewing machine upper arm 12, has secured thereto by bolts 24 a solenoid 25, and fulcrums on a stud 31 a bell crank lever 29, one arm 28 of which is pivoted at 27 to the armature 26 of solenoid 25. A block 51, clamped to the lower bearing bush (50) for the presser bar 18, has secured thereto by means of a screw 57 a block 56 co-operating with block 51 to clamp in position a pair of vertical guide tubes 60L, 60R. Slidable within the latter are respective rods L5L, (L5R) which are secured at their upper ends to a block 71 and at their lower ends to respective spring blades 62L, 62R formed at their free ends with respective points 63L, 63R and hooks 64L, 64R. Block 71 is pivoted at 37 to the other arm 35 of bell crank lever 29, and a spring 38 acts on arm 35 to bias block 71 upwardly for positioning the ends of the blades 62L, 62R within the tubes 61L, 61R. When the needles 16, 17 are raised at the end of a stitching operation, solenoid 25 is energised, whereby block 71 descends and the ends of the blades 62L, 62R are projected from the tubes 60L, 60R and are guided by the curved ends of the latter to traverse the paths of the needles 16, 17 and to engage the needle threads with the hook portions 64L, 64R. When solenoid 25 is de-energised, hook portions 64L, 64R again retract within the tubes 60L, 60R carrying the needle threads therewith. The device may be combined with the thread-severing means described in Specification 1,179,964, in which the machine initially stops with the needles lowered, then re-starts to raise the needles, when the thread-severing means operate, the thread-wiping means being arranged to operate slightly in advance of the threadsevering means.

Abstract: 733,201. Packaging ice cream. LYONS & CO., Ltd., J., and BOON, H. A. Nov. 16, 1953 [Nov. 14, 1952], No. 28780/52. Class 94 (1). A portion of ice cream is provided with a peripheral wrapper 2, Fig. 2, the edges of which stand slightly proud of the exposed ice cream surfaces whereby when several such portions are packaged and cold stored side-by-side without intervening separators, adhesion between the adjacent exposed ice cream surfaces is prevented. The wrapper may be formed with a flap 3 to facilitate its removal. The portions are prepared by enclosing a block 1 of ice cream, Fig. 1, in a container or tubular wrapper 2 having a seam with an overlapping flap 3, the ice cream being extruded into the wrapper and then frozen hard. The block is then cut into wrapped portions by pressing it against a frame comprising a series of reciprocating fine toothed saws or serrated knives 4, the teeth of which have no set, and the portions are disposed side-by-side in an outer wrapper or container. As the ice cream is made with a substantial air content, it is compacted by the saws or knives; the wrapper is also compressed, but due to its resilience it springs back after the cutting operation and stands slightly proud of the ice cream surfaces. The thickness of the wrapper is so chosen that this result occurs, the minimum thickness in the case of a cardboard wrapper being of the order of .015 inch.
