Title: Inking device for printing machines
IPC: B41K3/56
Filed: 1946-04-30
Abstract: 618,963. Typewriters &c. BRAUN, Inc., P. N. April 30, 1946, No. 13036. Convention date, July 13, 1945. [Class 100(iv)] Inking-apparatus.-The type-carriers of a printing-machine, shown as settable type-wheels 1 in a laundry-marking machine comprising a platen 6 carried by a rocking arm 8, are inked by a pad 14 normally in contact with a supply pad 11 and adapted to be moved by a reciprocating member 20 actuated from the arm 8 to ink the line of types in printing position and to return to normal position while the platen 6 is moving toward but short of the printing position, a normally-operative latch 17 being provided which is adapted to be released by a knock-off device before the platen reaches the printing position, and a spring 32 for returning the member 20 when the latch is released. The pad 14 is carried by an arm 15 rocked about a pivot shaft 36 by means of a pin 37 carried by a cam 21 pivoted at 34 to the member 20 which is slidable vertically. During the first part of the upward movement of the arm 8 which has a hub 9 turning about a shaft 10, an arm 16 mounted on the hub turns clockwise and pulls down the latch 17 which carries a stud 24 passing through a bracket 18 fixed to the member 20 whereby the latter descends causing the pad 14 to travel from the position shown in Fig. 3 to that of Fig. 11; a spring 26 between the bracket 18 and nuts 27 on the stud determines the pressure of the pad 14 on the types. A pin 31 on the arm 16 subsequently releases the latch 17 whereupon the pad 14 returns to normal position. The pad 14 is maintained horizontal by a rod 29 fixed to the pad carrier and passing through a swivel 30. The pad 11 consists of a wick dipping in a container 12. The pads, member 20, latch 17 and rod 29 form a detachable unit carried by a bracket 41.

Title: Improvements in and relating to electric primary cells
IPC: H01M6/24
Filed: 1923-05-18
Abstract: 220,094. Darimont, L. May 18, 1923. Addition to 180,120. Cells; diaphragms; gas exits; connections; electrodes; arrangement; charges in packages.-In order to precipitate a semi-permeable membrane within a diaphragm, in a cell of the kind described in the parent Specification, barium chloride and sodium bichromate, or barium carbonate and chromic acid, may be added respectively to the exciting and depolarizing solutions. When chromic acid is employed, it is advisable to add also a little barium chloride to the exciting liquid. The above materials, or those described in the parent Specification, may be packed in solid form. For instance, iron perchloride may be mixed first' with sodium chloride and then with hydrochloric acid, which is absorbed. The whole is placed in an acid-proof vessel, and chromic acid, enclosed in paraffined paper or other resistant material, is added; the vessel is then sealed. One or more carbons 2, 2<a>, Fig. 1, may be placed outside the porous pot, which contains a zinc electrode of the form shown in Fig. 2, or of similar shape providing gaps 10, connection being made at a point 9<a> least attacked during use. A sealing layer 6 is produced between the porous pot and cell, by nearly filling the cell with sand or the like and covering with molten wax, pitch, or the like, after which the sand is poured out through a funnel 8 previously inserted. This funnel, which is roughened or bound with wire to ensure adhesion of the sealing material thereto, is afterwards fitted with a split or perforated stopper. The upper parts of the carbons and porous pot are impregnated with paraffin or the like. Varying electromotive force may be obtained by providing a cell with several soluble electrodes of different metals, such as aluminium, zinc, and tin, capable of alternative use. These may form curved plates ranged around. a porous pot. Instead of earthenware, the porous pot may be of retort carbon, and serve also as electrode, being impregnated with a semi-permeable substance and having its upper portion waterproof.

Title: Improvements relating to x-ray apparatus
Inventor: STAVA ROBERT JOSEPH
IPC: G21K1/02
Filed: 1956-05-02
Abstract: 802,754. X-ray apparatus. PICKER XRAY CORPORATION WAITE MANUFACTURING DIVISION, Inc. May 2, 1956, No. 13549/56. Class 98(1) In X-ray apparatus having a grid mounted for movement with respect to an X- ray tube, an electric synchronous motor is connected to the source of A.C. supply for the X-ray tube, and mechanism driven by the motor for reciprocating the grid during X-ray exposure includes a gridengaging cam co-acting with the grid to provide a grid speed that is non-synchronous with respect to the frequency of the supply throughout the grid movement. As shown in Fig. 3, a frame 20 is slidable along rails 16, 17 mounted longitudinally below an X-ray table. The side walls 14, 18 of the frame have bottom flanges 23 slidably supporting a plate 30 carrying an X-ray cassette 35 in clips 36. The table has a slot along its side, through which the plate 30 may be pulled out to change the cassette. A Bucky grid 40 is supported above the plate 30 in a frame 41, Fig. 5, which is supported at one side by rollers 42 engaging flanges on the wall 18 of frame 20, and at the other side by brackets 43 sliding on rods 45, 46 mounted in brackets on the wall 14 of frame 20. The grid is movable to and fro by means of a heartshaped cam 52, Fig. 6, driven through gearing from an electric synchronous motor 60 and engaging rollers 51 on a bar 50 connected to one of the brackets 43. The grid - reciprocating mechanism is mounted on wall 14 of frame 20 and enclosed by a removable housing 70. If the exposures are long enough to include several strokes of the grid, the phase of grid movement at which the exposure is initiated does not matter and all that is needed is a switch for the motor 60 and an exposure-controlling switch, or a common switch for both. When the apparatus is to be used for shorter exposures, a pair of cams are mounted on the shaft of cam 52, and these cams operate switches connected in an electric circuit in such a way that an exposure cannot be made at the time when the grid is reversing. The X- ray tube is connected to the same source of alternating current as the motor, and the gearing between the motor and the cam is preferably so designed that the grid moves through a distance covering ten of its slats during thirteen cycles of the alternating current, though other relationships which avoid grid shadow are permissible. Any change in the alternating current frequency affects the motor speed, so that the relation of the grid speed to the current cycle remains constant.

Abstract: 434,708. Speed and distance indicators. PAULIG, O., 9, Hansastrasse, Lubeck, Germany. May 9,1935, No. 13677. [Class 106 (iii)] Speed and distance indicators for use on vehicles including ships comprise friction wheel gearing operated by two pendulums which interact on one another so that one pendulum b is set according to the acceleration while the other c is set in the vertical position. The pendulum b consists of a cylindrical sector pivoted within a fixed cylinder a and supporting the spindle d of the second pendulum comprising a hollow cylinder c. Within the cylinder c is a clockwork-driven disc f driving a disc g which drives a friction wheel k mounted on a carriage h slidable in the cylinder c, the wheel k driving a counter m. A friction wheel o driven by the disc f has a toothed spindle n operating a rack on the carriage h. The spindle n and another spindle r carrying a balance weight s are axially displaced by cams p, q carried by the cylinder b, the cams being designed to stop the rotation of the cylinder c and to effect a displacement of the wheel o from the centre of the disef in linear relationship to the acceleration. The speed may be read on a drum provided on the wheel o or by divisions on the carriage h, while the drum l and counter m give the distance travelled. A second apparatus arranged perpendicular to the first may be used for simultaneous measurement from a second plane of reference. To minimize friction on the cams p, q, the ends of the spindles n, r may be fitted with small rollers. Contact between the parts n, p, q, r may be ensured by magnetizing them.
