Title: Improvements in or relating to grinding and polishing tools
Inventor: OSENBERG WERNER
IPC: B24D18/00
Filed: 1955-06-18
Abstract: 790,003. Moulding grinding and polishing tools. BISTERFELD, E., [trading as BISTERFELD & STOLTING]. June 18, 1955, No. 17678/55. Class 87(2). [Also in Group XXIII] A grinding or polishing tool is made by filling mould with abrasive grains, compacting the grains by vibration, subjecting the compacted grains to pressure to form a rigid skeleton and, while maintaining the grains under pressure, injecting thermoplastic or thermosetting material into the mould so as to partly or wholly fill the spaces in the skeleton. In Fig. 2 abrasive grains 1 are filled into a die 5 having a base plate 8 through which projects a spindle 9 that is to form part of the abrasive article, then the grains are vibrated and subsequently compressed by a ram 7, and then synthetic material is injected into the die through a passage 10 in the ram. During injection, pressure is maintained by the ram. Air escapes from the die through passages 11, 11<SP>1</SP> in the base. In Fig. 5 a perforated steel disc 14 is faced with abrasive grains, the injection taking place through two passages 10 in the ram and runners 10<SP>1</SP>. Fig. 6 shows the making of a tanged file the injection being end-on. The making of spheres and bevel wheels is described. Fig. 11 shows a wheel having zones of fine and coarse abrasive grains. Fig. 12 illustrates the making of a cylindrical tool 14 having abrasive strips 6<SP>1</SP>, 6<SP>11</SP> moulded. into grooves in the surface thereof and anchored therein by inserts 16<SP>1</SP>, 16<SP>11</SP>. Strips 4, Fig. 1d, may be dissolved or etched away after moulding has been completed (to leave recesses for grinding dust). In general : Air may be exhausted from the die. Porous grinding tools may be made by forcing gas or liquid through the die after injection of the synthetic material, the gas &c. washing out part of the material: or sucking out part of the material : or part of the material may be removed by centrifugal action : or surface porosity may be achieved by mixing granular ceramic material or glass with the abrasive material before it is filled into the die, this granular material falling out during use. Non-metallic fabrics may be embedded in the abrasive material. Spindles &c. to be embedded in the articles may be initially coated with a mixture of abrasive and synthetic material to assist adhesion : or may be roughened, contoured &c. for that purpose. The dies used may be " lost " moulds, made of porcelain, glass, wood or rubber, reinforced during moulding with a steel jacket. The dies may be coated with liquid paraffin release agent.

Title: Improvements in and relating to conductors for making electrical connection with mercury
IPC: H01H29/04
Filed: 1921-06-30
Abstract: 183,683. British Thomson - Houston Co., Ltd., (General Electric Co.). June 30, 1921. Mercury switches.-A low resistance connection is obtained with the mercury in electric switches, rectifiers, arc lamps &c. by means of an oxidizable refractory metal by tipping it with a metal the oxide of which is reducible at a lower temperature than the oxide of the refractory metal. Tungsten, molybdenum, &c. tipped with nickel, iron, &c. may be employed. Leading-in conductors for a mercury switch for example are constructed by drawing an arc between tungsten wire and a nickel wire in hydrogen and dropping a bead of nickel 11 on the end of the tungsten skin. This is then sealed into a glass flare 12. The flare is sealed into the glass container and the whole annealed. The entire bulb is next heated to about 300‹ C., at which temperature the nickel is subjected to the reducing action of hydrogen repeatedly introduced into the container. The nickel may in this state amalgamate with the mercury. After reduction, mercury is inserted under vacuum, and the bulb is filled with dry hydrogen at atmospheric pressure and sealed. The lead wires may be secured to the leading-in conductors by arc-welding to a nickel tip formed on the tungsten wire as described above.

Title: Improvements in methods of manufacturing sintered porous plastic plates or webs
IPC: B29C67/20
Filed: 1959-05-27
Abstract: 874,192. Moulding battery separators. JUNGFER, L., [trading as AKKUMULATORENFABRIK Dr L. JUNGFER.]. May 27, 1959 [May 28, 1958], No. 18122/59. Class 87(2). Sintered porous plastic plates, having longitudinal hollow ribs or other hollow profiles and suitable for use as battery separators, are produced by heating and pressing a plastic powder layer, for example of polystyrene, between a rigid press member having raised portions shaped according to the desired inner hollow profile and a resiliently yieldable press member so that the compaction is mainly effected adjacent said raised portions and the resultant ribs &c. are substantially non- porous. A layer of polystyrene 1 supported on glass wool fibres 2 is passed between an upper roller 8 of silicone rubber and a lower rigid roller 7 having spaced annular 7a so that the continuously issuing plate has hollow longitudinal ribs 1a substantially free form pores adjacent their apices. The powder is sintered during this pressing operation. In the embodiment of Figs. 1-3, (not shown) the plates are pressed between an upper resiliently yieldable die and a lower die with raised longitudinal ribs. Specification 807,385 is referred to.
Patent GB-776670-A (GB)
Title: Improvements in or relating to apparatus for the electronic counting of objects
Inventor: BURROWS DEREK RAYMOND
IPC: H03K21/00
Filed: 1954-06-21
Abstract: 776,670. Counting objects. CINEMATELEVISION, Ltd. June 21, 1955 [June 21, 1954], No. 18132/54. Class 40 (3). Apparatus for the electronic counting of objects comprises a storage target upon which a charge image of an area containing objects to be counted is arranged to be formed, means for scanning the charge image with an electron beam, means responsive to the incidence of the beam upon a part of said image corresponding to an object and arranged to effect a change in beam conditions such as to erase said part of said image and to record a count, and means operating upon the cessation of said response to re-commence the scan and restore the initial beam conditions. As shown in Fig. 1, an object containing area 1 is focused by lens 3 on the photo-cathode 4 of a television camera tube 5 of image-orthicon type and a charge image of the area is formed on a storage target 6 of double-sided type. This target is scanned by an electron beam from a gun 8 and the secondary electrons emitted when the beam encounters a part of the charge image corresponding to an object are collected upon an electrode 13. The resulting signal is applied to a device 14 which is connected so as to stop temporarily the scanning and to register one count upon counter 15. Device 14 also serves to defocus the scanning beam until the whole of the image of the object encountered has been erased from the target. Thereafter normal scanning is resumed until the charge image of another object is encountered. In another form, Fig. 2, an area 21 is scanned by a.device 23 to produce signals which are applied to a device 24 whereby the intensity of the electron beam in a storage tube 25 is controlled. The signals derived from device 23 are recorded on target 27 of tube 25 by applying them to the modulating electrode of the gun 26 in such polarity that those areas of target 27 corresponding to an object in the area 21 acquire a positive charge. The recording action is then stopped and the velocity with which the beam strikes the target is reduced so that when a positively charged area of the target is encountered a signal is produced at the target signal plate 32. This signal is applied to a device 33 which registers one count upon a counter 34 and arrests the scanning. Device 33 also defocuses the beam so as to erase the image encountered. Thereafter, normal scanning is resumed. In a modification of the spot defocus system the spot is caused to be deflected on to the unscanned area of the target, preferably so that its distance from its original position varies exponentially with time, while the defocusing action is such that the spot diameter increases linearly with time. Also, when the scanning spot encounters an image of an object it may be arranged that the spot follows the object's outline until the image thereof has been erased.

Title: Process for casting of metallurgical ingots of great length
IPC: B22D11/06
Filed: 1937-07-01
Abstract: 498,294. Casting-machines. COMPAGNIE DES FORGES DE CHATILLON, COMMENTRY, & NEUVES MAISONS, and THIBAUDIER, L. July 1, 1937, No. 18297. [Class 83 (i)] Metal pouring.-In continuous casting the metal is projected, as by a channel C, into a longitudinally moving mould in the direction of its movement and at a greater speed. The speed of the mould should bear a constant relation to the rate of feed of the metal or should gradually decrease in relation thereto. If the speed of the mould is constant the desired rate of flow may be obtained by keeping the level in the ladle substantially constant or gradually rising. If the feed of metal is not regulable the speed of the mould is varied by simple mechanical or electrical means in accordance with the observed appearance of the metal at d. In order to assist in obtaining the desired tranquil solidification, longitudinal movement of the metal relative to the mould may be assisted or retarded by a correspondingly directed current of air or other fluid. Partitions may be inserted in the mould at a point just before the metal feed is cut off and also where it is desired to form separate ingots of the same or of different thickness h &c. Specification 273,311, [Class 83 (i)], is referred to.

Title: Noise silencing type bar actuating arrangement for typewriters
IPC: B41J7/02
Filed: 1936-07-02
Abstract: 474,997. Typewriters. AKT.-GES. VORM. SEIDEL & NAUMANN, and BENZING, H. July 2, 1936, No. 18396. [Class 100 (iv)] Type - lever actions.-A noiseless type - lever action comprises type-levers positively moved into a " ready " position by the key-levers, in which position the key-levers are stopped, the type-levers continuing to move towards the printing position under momentum, independently of the key-levers and against the action of a spring, which does not exert a returning force on the keylevers. The type-lever 1, Fig. 2, is linked at 2a to an intermediate lever 3a, pivoted at 4 and operated by a link 10, a rocking lever 7 and the key-lever 6. To prevent the lever 7 being raised from the rolling surface 14 when the lever 1 moves faster than the lever 6, a pin 25 is provided on a tail 23 of the lever 3a and runs on a curved edge 26 of a tail 27 of the lever 6. The edge 26 is so shaped that the system of levers is locked together and there can be no noisy play in any position. The stroke of the key-lever 6 is limited by an adjustable stop in the form of an eccentric 28 secured to the tail 27. The eccentric 28 and pin 25 move in the same direction, though at different speeds so that there is no shock when the key-lever is arrested. The type-lever is connected to lever 3a through a sub-lever 31, pivoted to lever 3a and having a lost-motion connection therewith comprising a pin 32 and padded aperture 33. When lever 3a is checked further motion of the type-lever is retarded either by lever 31 pressing against a spring 35 on the lever 33, or by a spring 22a, which also operates the universal, bar and is coupled to lever 31 or 3a, or by both. In a portable typewriter action the key 44, Fig. 6, operates parallel levers 46, 47. A bell-crank lever 52 is pivoted to an arm 51 of the lever 47 and coupled thereto by pin 55 and slot 54. One arm of the lever 52 engages the resiliently mounted universal bar 57 and the other operates the type-lever 41 through a link 58. A spring 61 is stretched between the link 58 and typelever 41. The depression of the key 44 is arrested by the engagement of an adjustable eccentric stop 65 with the lever 47. The momentum movement of the type-lever 41 is then braked by the spring 61 and bar 57, acting on the independently moving lever 52. On the return movement of the levers the lever 46 is overtaken by a stop 63 before the typelever strikes its seating 64.
