Title: Knife sharpener
IPC: B24D15/06
Filed: 1951-06-28
Abstract: 697,054. Knife sharpeners. HIBBARD, C. G. May 20, 1952 [June 28, 1951], No. 15395/51. Class 60. A knife sharpener has a steel 16 removably and rotatably supported in a frame 10. The base 11 of the frame has holes 19 for screws 20 securing it to a base block 21 which may in turn be secured to a bench, wall or other surface by screws passing through holes 22; alternatively, the frame 10 may be secured directly to a bench, wall or other surface. Reduced ends 15, 17 of the steel are received in a hole 14 and a slot 18 in the end brackets 12, 13 of the frame; the upper portion of one or both end brackets may be bent slightly away from the vertical in a direction away from the other end bracket to facilitate insertion of the steel. In a modification, Fig. 2, one end bracket 23 is twisted to form a loop in which the reduced end of steel is inserted and secured by tightening a screw 25. In a further modification, Fig. 3, each end bracket 32, 33 is twisted to form one jaw 35, a separate jaw 36 being secured thereto by screw 25. Alternatively, the jaws 36 may be riveted to the upper parts of the end brackets so as to form spring clips. The sharpening steel is rotated about its longitudinal axis when it becomes worn. The steel and the frame are preferably magnetised so that particles of metal removed from the blade during sharpening are retained upon the device; the steel serves as a keeper to the magnetised frame so as to reduce demagnetisation.

Title: Improvements in or relating to sterilising materials in flexible packages
IPC: B65B55/16
Filed: 1964-04-14
Abstract: 1,027,874. Sterilizing and vacuumpacking moisture-containing materials. CONTINENTAL CAN CO. Inc. April 14, 1964 [Aug. 30, 1963], No. 15428/64. Heading A2D. Moisture containing products of relatively high dielectric constant, such as foods, chemicals and pharmaceuticals are simultaneously sterilized and vacuumpacked by placing the product in an opencopper porch of a low dielectric constant polymer film material, such as polyethylene, polypropylene, and polyethylene terephthalate, sealing only portions of the top of the pouch so as to provide a passage way, subjecting the thus packaged product to the action of electromagnetic energy in the microwave range thereby rapidly heating the product to about 100 degrees C, the evolved steam escaping, together with air, through the unsealed portions of the top of the pouch, and thereafter immediately sealing the top of the pouch. In examples, stewed tomatoes and whole ripe raspberries were packaged. In Fig. 1, open top pouches 7 are dispensed from hopper 16 into supports 12 on conveyer belt 9, which are of low dielectric constant, the moisture containing product is dispensed into the pouch from hopper 19, the top of the pouch is closed by guides 23, 24 and partly heat sealed by rollers 26, 27, giving a seal 29 having passageways 30, as shown in Fig. 2. The package then passes through microwave oven 6, and the sealing is completed by guides 31 and rollers 32 and 33. The sealed package falls upside down on to conveyer 34 via guide 35, thereby ensuring that any bacteria remaining in the headspace 21 of the package are destroyed. Fig 4 shows an alternative heat seal, without any corners which can retain bacteria which escape the steam generated.

The chamber G is then filled to a level above the top oil the tube D, and pumping is discontinued. The tube D is then lowered to a set position, the overflow running through it to the underground tank. The delivery valves are then operated to deliver the measured quantity remaining in the chamber G.

Title: Improvements to precision machine tool with automatic control of its slides
IPC: G05B19/39
Filed: 1941-12-04
Abstract: 555,792. Drilling. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Dec. 4, 1941, No. 15658. Convention date, Dec. 28, 1940. [Class 83 (iii)] [Also in Group XL] The work table of a precision centre-punching machine which is driven at a high speed towards the desired position by a motor is slowed down before it reaches the desired position by mechanically or electrically controlled devices and is then stopped accurately by a photoelectrically controlled device. The tool, which is adjusted transversely over the work table, may be positioned by similar automatic means or by hand. The work table 31, Fig. 3, is moved by a feed screw 35 driven by a motor 41 through a gear box 13, shaft 14 and gearing 33, 34. A hand wheel 24 is provided for independent or preliminary adjustment of the work table. The gear box 13 includes a clutch 27, Fig. 2, having upper and lower positions for low and high speed respectively and an intermediate disengaged position, the member 27 being actuated by an armature 26 pivoted at 28 and operated by two electromagnets 11, 12 controlled by a relay 10. The preliminary slowing down is controlled by an index member 16 attached to the table adapted at the proper moment to trip a lever 18 to open a switch 19 connected to the relay 10. The final stopping is controlled by a photo-electric cell 9 connected to the relay device 10 and subjected to light from a lamp 40 through an optical system including groups of marks 2a on a scale 1 attached to the work table and a corresponding screen 8 adjustable by a micrometer screw 37. The control circuit of the cell is normally cut off by a switch (not shown) which is automatically operated to prepare the circuit for operation just before the work table reaches its desired position. The scale 1 also carries marks 3a for observation by a microscope 7, when making hand adjustments. In operation, the pointer 16 is set to a mark on the scale 15 just short of the desired position and the screen 8 is adjusted for the additional travel required. The motor is started to drive the work table at high speed towards the desired position. Just before that position is reached, the pointer 16 trips the lever 18 and opens the switch 19 whereupon the relay device 10 throws the clutch 27 to the slow driving position and the circuit of cell 9 is prepared for action by its switch. When the work table reaches the exact position desired, the image of the groups of marks 2a coincides with the corresponding groups of marks of the screen 8, and the sudden change of illumination on the cell 9 causes the relay device 10 to switch off both magnets 11, 12 whereupon the clutch member 27 takes its mid position and the work table stops. The photo-electric device is similar to that described in Specification 558,848, [Group XL].

Title: Process for forming metal phosphides and mixtures containing them
IPC: C22C32/00
Filed: 1926-06-25
Abstract: 276,112. Koehler, W. June 25, 1926. Metal phosphides are produced by mixing the component elements in finely-divided condition and subjecting the mixture to pressure with or without heating. When red phosphorus is used, the heat treatment is essential. According to an example, ground precipitated copper is mixed with finely-comminuted phosphorus and the mixture is subjected to pressure in a mould. The phosphorus may be finely comminuted by dissolving it in carbon bisulphide or other solvent, the latter being eliminated only after mixing with the metal. Specification 11415/10 is referred to.

A mercury switch 26 is carried in a framework 22 pivoted at 23 below its centre of gravity such that it is stable when tilted to either side of the vertical and is coupled to a Bourdon tube 16 by a member 18 which is pivoted at 20 to the switch carrier and at the other end to a link 17. Member 18 carries an adjustable pin 42 for co-operation with adjustable abutment rails 44 and 66 which determine the upper and lower pressures at which switch 26 is operated; between these limits member 18 pivots freely at 20 and does not affect switch 26. When pin 42 engages the appropriate rail 44 or 66 it acts as a fulcrum and pivot 20 is moved up or down, respectively, thus moving switch 26 through its vertical position to fall with a snap action on the other side. The rails 44 and 66 are carried on members pivoted at 48 and spring- loaded to urge cam followers 55 and 76 thereon against circular cams 56 and 78 respectively (only fragments being shown in Fig. 3). Cams 56 and 78 are mounted on an annular bushing at the centre of a dial plate (Fig. 1, not shown), and have pointers whereby they can be rotated to adjust the rails 44 and 66. The centre of the annular bushing forms a window through which switch 26 can be observed.
