Title: Mechanical pencil
IPC: B43K21/08
Filed: 1922-02-09
Abstract: 196,130. Fischer, H. L. Feb. 9, 1922. Pencil-holders.. erasers. - In a pencil-holder of the type in which the propelling- mechanism is formed of separable sections, the parts of the mechanism are held together against relative longitudinal movement by a spring sleeve carried by one of the sections. The propelling - mechanism comprises a screw-threaded member 15, a slotted tube 16 and a lead-carrier 28 formed with a socket 32 for the rear end of the lead and springs ends 29, 30 to force the teeth 31 into engagement with the screw-threads of the member 15. The member 15 is spaced from the barrel 10 to form a receptacle for spare leads by collars 17, 18 secured respectively to the front and rear ends, the collar 18 screwing into the rear end of the barrel. The rear end of the slotted tube 16 is fixed in an operating-head 22 which is formed with an extension, a part 25 of which is knurled to serve as a finger-piece and the other part is recessed to contain a divided spring sleeve 26 accommodated, when the parts are assembled, in a cylindrical recess in the collar 18. The head 22 is provided with an eraser 39 covered by a cap 40 having an oval - shaped shank fitting on the head with greater friction than that exerted between the parts 26, 18, so that, when the cap is pulled outwardly, the tube 16 is drawn out. The forward end of the slot in the tube 16 is closed by lugs to prevent the disengagement of the lead-carrier 28 from the slot, so that, in order to remove the tube 16 from the member 15, it must be rotated to disengage the teeth 31 from the screw-threads. To uncover the eraser, the knurled part 25 of the head 22 is held and the cap 40 pulled off. A bead 42 on the shank of the cap engages a shoulder on the head to prevent jamming. The collar 17 at the forward end of the member 15 is formed with a conical inner surface 45 so that, after the tube 16 has ben removed and the pencil inverted, any broken pieces of lead may be readily discharged from the point section through the member 15.

IPC: B08B9/32
Filed: 1925-02-12
Abstract: 230,428. Andersson, A. March 5, 1924, [Convention date]. Bottles, washing.-In machines wherein the bottles are supported in an inverted position on a horizontal intermittently-revolving table for treatment by jets of washing and rinsing fluids, the jetting conduits are detachably fastened to the outside of the casing of the machine so as to be readily removable. The table 2 carries holders 4 for the bottles 3 and rotates about a fixed vertical shaft 1 so that the bottles pass over lower conduits 6 having nozzles 7. Each conduit passes through a hole in the casing 5 and has a flange, 8 secured to the outside of the casing by thumb-screws 9, so that by disconnecting the pipe-joint 11 connecting the conduit 6 with the main supply pipe and removing the thumbscrews 9 the conduit may be removed without interfering with the working of the rest of the machine. The upper conduit boxes, though not so shown, may be made readily removable like the lower ones.

Title: Cutting device
IPC: C14B5/00
Filed: 1963-02-01
Abstract: 969,431. Cutting apparatus. C. P. MEEK. Feb. 1, 1963, No. 4194/63. Heading B4B. A cutting device 1, for preparing a skin section for grafting, comprises a supporting member 5 having mounted on it a lamina 63 of e.g. cork, a lid 41 overlying the lamina 63 and having formed in it ribs 51 defining spaced longitudinal slots, and a cutter assembly 97 mounted above the mounting block for movement in the direction of and extending through the slots for contact with material clamped by the ribs between the lid and lamina 63. The lid 41 is hingedly connected at 43 to the supporting member. In operation, a section of a split width skin graft 65 is positioned on the lamina 63, and the lid 41 is closed and locked. The cutter blade frame 67 is moved by its handle 79 along the guide channels 77 across the supporting member 5 so that the rotating blades 97, which are protected by L-shaped guard members 109 and driven via a connector 105 and flexible connection 107, cut the central area of the skin 65 into strips. The frame 67 is then withdrawn and the lamina 63 turned through 90 degrees and a further cutting movement is made so that the skin is cut into a number of minute cubes which are removed and put into a liquid suspension.

Abstract: 1,015,802. Discharge lamps; securing end caps to envelopes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 20, 1963 [Feb. 1, 1963], No. 4311/63. Addition to 889,941. Headings H1D and H1J. The method of manufacturing a tubular discharge lamp disclosed in the parent Specification is modified-to permit the maintenance of the tubular envelope and the end caps at an elevated temperature during evacuation-by the use of glass end-caps having a coefficient of expansion substantially equal to that of the envelope, and by the inclusion in the apparatus of electric heaters for heating the end caps and the adjacent envelope portions; the further modification of assembling one of the two end caps in a conventional manner is also referred to. Closure blocks 25 are removed from the ends of stainless steel heater tube 15, and the phosphorcoated, open-ended glass tube envelope 1 introduced therein and the coating baked free of binder by passing a current of air through tube 15 and a heating current between contacts 21. Tube 15 is then closed by blocks 25, each of which supports a glass end-cap for the envelope within a ceramic ring mounted on an axially movable rod 29. Tube 15 is evacuated while maintained at a high temperature by the passage of current between terminals 21; cathode heaters or wires 9, which are supported by their contact pins which pass through their respective end caps, are degassed by passing a current therethrough; evacuation is stopped and a mercury dope through tube 41, and an inert gas, is introduced; the end-caps are raised to a higher temperature by annular electric heaters mounted in rings 33 and spaced from the cap peripheries; and rods 29 are forced inwards to seal the end-caps to the tube 1. Tube 15 may be large enough to permit batch production, or continuous production may be obtained by employing the method of the present Specification with apparatus similar to that disclosed in the parent Patent.

Title: Improvements relating to artificial teeth
IPC: A61C13/08
Filed: 1945-02-22
Abstract: Relates to methods of moulding artificial teeth (see Group V) in which there is united to a "dentine" body of relatively opaque material an outer layer of translucent material corresponding to the enamel layers of the natural tooth. Reference is made to the use of porcelain, stained glass and plastics, e.g., acrylic resins.  The "enamel" layer may be 2-3 parts clear acrylic resin mixed with 1 part of the shaded resin used for the "dentine" body.
