Title: Improvements in or relating to ink ribbon mechanism for typewriters and like machines
IPC: B41J35/22
Filed: 1932-11-10
Abstract: 409,762. Ink-ribbon mechanism. BALDWIN, R. E., 33, Knatchbull Road, Camberwell, London. Nov. 10, 1932, No. 29141. [Class 100 (iv).] In a duplicating arrangement for typewriters and like machines a plurality of ribbons or lengths of ribbon pass through slidable guides which can be retracted from the platen to separate the ribbons. In the arrangement shown in the Figure, the ribbon passes from one roll to another around a series of pulleys (not shown) which are mounted on plates 4, and which guide the ribbon in a series of bights across the face of the platen P. Each length of the ribbon passes through two guides 2<c>, 2<a> arranged near either end of the platen and mounted on slides 2d, 2f on the plates 4. The guides are moved to separate the lengths of ribbon, to permit insertion of sheets of paper, by finger-pieces 2<g>, 2<k>, and are provided with lugs 9<a>, 9<c>. The plates 4 are hinged to the carriage at 5, and the carriage is provided with a projection 8 which, when the plates 4 are in a lowered or printing position, engages the lugs 9<a>, 9<c> and prevents retraction of the ribbon. When the plates are raised however the guides may be retracted and the lugs 9<a>, 9<c> will then engage the top of the projection 8 and prevent the return of the plates 4 to lowered position until they have been restored. A paper-knife 10 is hinged to the carriage and serves to hold back some of the bights of ribbon to permit the introduction of the paper sheets. The pulleys themselves may be slidable or may be replaced by fork members. A plurality of ribbon spools may be used with or without the pulleys, or a plurality of ribbons may be fed from each spool.

Abstract: 873,041. Television pick-up tubes. ENGLISH ELECTRIC VALVE CO. Ltd. Feb. 11, 1960 [Aug. 27, 1959], No. 29312/59. Drawings to Specification. Class 39(1). In a television camera tube, e.g. of the image orthicon type, the signal storing target structure includes a very thin partially conducting membrane, e.g. of glass, formed with at least one stiffening web arranged to resist diaphragm-like vibration of the membrane. Preferably, a single rectangular stiffening web is provided, surrounding the useful picture area of the target, the height of the web being equal to the spacing, -e.g. 0.002 inches between the target and the adjacent control mesh or grid. The web may consist of a ridge formed in the membrane, or of a separate rectangular glass frame sealed to the membrane, Alternatively, the membrane may be dished so as to have an inner part in one plane and an outer part in an adjacent parallel plane, the stiffening web being constituted by the perpendicular wall joining the two parts.

Title: Rock splitting apparatus for mechanically breaking rock
IPC: E21C37/02
Filed: 1973-06-20
Abstract: 1411504 Rock splitting H DARDA 20 June 1973 [20 June 1972] 29351/73 Heading E1F In a rock splitting apparatus in which two members 14, 15 insertable into a bore hole are separable by a hydraulically driven wedge 15, the separable members are so mounted as to be capable of relative longitudinal movement to absorb any differential loading. As shown in Fig 1 portions 14b, 15b of the separable members are relatively movable against restoring springs 14e, 15e in an element 13 secured to the cylinder (not shown) of a hydraulic operating ram. A resilient rubber disc 17 serves to center the separable members which extend between bars 19 restrained from longitudinal displacement, see Fig 2. In the embodiment shown in Fig 4 an element 29, formed from two face to face discs, is rotatable about an axis perpendicular to the drawing, and has slots 29a which are engaged by shoulder portions 24b, 25b of the separable members 24, 25. Restoring springs 24e, 25e act on the shoulder portions and the bearing surfaces of the slots 29a have radii of curvature which increase on either side of the rest position shown. The separable members have a tongue and groove interengagement at their lower end, Fig 7. This arrangement is modified (Figs 9-12, not shown) by the provision of ball bearings engaged between bearing rings on the element 29 and complementary bearing races formed in the element 23; moreover the separable members are formed from relatively thin steel strips one of which engages between the forked ends of the other. In a further embodiment (Figs 13-17, not shown) the discs constituting the rotatable element are held together by bolts: of which two engage in slots in the separable members, and two are acted on by restoring springs. In all cases the sliding contact faces of the wedge and separable members are provided with welded-on hard metal layers for wear resistance.

Drilling.-A two-speed gear adapted for a hand bench drilling-machine comprises a driving flywheel a which is moved bodily to an eccentric position with respect to its driven spindle d in changing from normal to high-speed drive. A toothed pinion c fast on the spindle d carries clutch dogs g, which in the normal-speed position shown engage a dog projection f upon the face of the wheel a. The wheel a is secured to a stud e which is supported in a boring in the end of the spindle, d. To change speed, the wheel a and stud e are withdrawn bodily, and the stud is fitted into a hole i in the machine frame j. An internally-toothed wheel b upon the face of the wheel a is thus meshed with the pinion c, which can thus be driven faster.

Abstract: 648,073. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., BAGSHAW, C. M., and LANE, H. Nov. 17,. 1948, No. 29863. Addition to 598,216. [Class 17(i)] The machine of the parent Specification is modified to deal with relatively thick and resistant platform cover material by imparting to the grippers which apply tension thereto movement in a path which in its early part has a component heightwise away from the shoe bottom and then inwards of its edge. Later in its inward movement it moves toward the shoe bottom, and the return movement is generally the same as in the earlier machine. For this purpose, the carrier 32, through which the rear jaw 10 of the gripper is operated, is given a heightwise movement by engagement of a cam 41 having two inclined faces 43, 45 making an angle of about 30 degrees with the horizontal plane, mounted on the machine frame by a cam member 47 secured to the carrier 32 and having complementary faces 49, 51 arranged to co-operate with the faces 43, 45 respectively. The cam 41 may be depressed against a spring 65 (not shown) by an abutment 67 on a lever 242 on forward end of which presser feed foot 16 is mounted, to permit the gripper to be moved into, and maintained in, its fully lowered position during the return movement of the gripper rear jaw. Specification 613,392, [Group XXVI], is referred to.

Title: Improvements in or relating to the cleaning of uranium waste
Inventor: FLINT OLIVER
IPC: C23G1/10
Filed: 1950-12-06
Abstract: Uranium in the form of swarf, turnings or the like machining waste is cleaned by treatment with an aqueous solution containing a dicarboxylic acid and a ferric salt of a dicarboxylic acid.  The uranium is preferably initially compressed to form a compact which is then broken down for treatment.  If the metal is heavily coated with hydrocarbon oil it should be degreased prior to cleaning. The dicarboxylic acid may be oxalic acid, malonic acid, succinic acid or malic acid, and the ferric salt may be ferric oxalate. The solution may also contain a surface-active agent and an emulsifying agent. After cleaning, the uranium is washed, dried by means of a centrifuge, and then formed into desired shapes by compacting.
