Title: Adjustable resilient-tipped writing instruments
IPC: B43K7/12
Filed: 1964-09-16
Abstract: 1,071,219. Retractable ball - point pens. PARKER PEN CO. Sept. 16, 1964 [Sept. 18, 1963], No. 37869/64. Heading B6P. In a retractable ball-point pen, the cartridge is mounted to yield resiliently in the projected writing position, and the degree of resiliency is capable of adjustment. The rear push-button actuated ball-point pen, Fig. 1, is of the type having the cartridge 17 fixed to a tubular cam member 25, both being capable of axial and rotational movement in unison and biased in the retracted position by a spring 22. A tubular detent member 26 is provided with internal, diametrically opposed detent ribs 31 and 32, which co-operate with diametrically opposed slots 36 and 37 in a plunger 35, Fig. 2. Additionally, a tubular detent adjustment member 27 is provided, which has radially inward projections which also co-operate with slots 36 and 37. The adjustment member 27 is threaded at 28 to the connector member 29 which joins the front and rear portions of the pen barrel. A spring 46 stronger than spring 22 and positioned between the adjustment member 27 and the detent member 26, biases the detent member 26 downwards against the rearward surface of the connector member 29, and through the ribs 31 and 32 biases the tubular cam member 25 and cartridge 17 downwards against the spring 22. This spring 46 therefore provides the resilient mounting of the ball-point cartridge within the pen body, and its degree of compression can be altered by rotating the pushbutton 39, which in turn rotates the plunger 35 and detent adjustment member 27, the latter being threaded on or off the connector member 29, thereby altering the relative axial distance between the adjustment member 27 and the detent member 26 which alters the compression in the spring 46. Depression of the push-button 39 against the bias of spring 38 brings the cam surfaces of the plunger 35 into co-operation with cam surfaces of the cam member 25, which has the effect of stepping the cam member 25 through 90 degrees to allow the detent ribs 31 and 32 of the detent member to take either of two positions; against the stop surfaces 59 and 61 of the cam member 25 when the cartridge is in projected position (Fig. 7), or against the bottom surfaces 54 and 55 (Fig. 5), when in the retracted position. In an alternative embodiment (Fig. 9), the detent member 26 and the adjustment member 27 are replaced by a single detent element (71). The element (71) is provided at its forward portion with a helical undulate cam surface, which is biased into engagement with a cam follower forming part of the connector element joining the front and rear portions of the barrel. The biasing force is achieved with a spring which provides the resilient mounting of the ball-point cartridge. Rotation of the push-button rotates the detent element which is displaced axially by the cam follower co-operating with the helical undulate cam surface. This alters the compression in the biasing spring and therefore the degree of resilience in the mounting of the ball-point cartridge.

Filed: 1969-07-28
Abstract: 1278282 Wire strippers IDEAL INDUSTRIES Inc 28 July 1969 37873/69 Heading B4W [Also in Division H2] The operation of a pair of handles 18, 20 of a wire stripper causes gripping and cutting blades 62, 78 respectively to slide towards fixed blades 58, 76, and also the opening and closing of a pair of pivoted levers 12, 14. The handles have arcuate slots 86, 88 enabling them to move about rollers 90, 92 fitted on pins 94, 96 extending into the levers and hence cause projections 102 which engage slots (106, 108) in the blades to slide the blades. When the rollers are at the limit of the slot travel, further compression of the handles causes the levers to open against the spring 110 and move the blades away from each other axially of the wire. The spring is wound about the lever pivot pin 36 with ends 114, 116 free to move within the handles. Thus the gripping and cutting of the insulation is followed by a lateral motion, separating the insulation from the wire. The movable blades have slots 74 enabling them to slide about fixing bolts 56 and spacers 70 of the respective levers. The cutting blade is formed with several openings of different diameters and to ensure the centralization of the wire within the blades, the gripping blades have a lateral divergence in the direction of the largest opening.

Title: Method of and apparatus for reading characters formed by a plurality of areas
IPC: G06V30/224
Filed: 1970-08-06
Abstract: 1308228 Character recognition CIBAGEIGYAG 6 Aug 1970 [7 Aug 1969] 38071/70 Heading G4R A character formed of areas of equal size, each positioned at a row-column intersection of a matrix, is read by scanning 3 rows to produce, for each row, a signal representing the total number of areas in the row, a 4-bit code being derived from these signals to represent the character, the fourth bit being utilized to indicate the occurrence of the maximum number of areas in a predetermined one of the three scanned rows. The character matrix has 5 rows and 4 columns with holes at selected intersections and is moved vertically past a horizontal slit illuminated via a diffuser, each row in turn producing an analogue voltage representing the number of holes from a photo-cell via an optical filter. Amplifiers with thresholds of 1, 2 and 4 (holes) receive these signals. The first of the 5 pulses from the 1 thresholder produces an enabling signal for the coder, and these 5 pulses are counted, the counts being decoded to enable appropriate ones of 4 flip-flops to respond to outputs of the 2 and 4 thresholders, the fourth flip-flop, if set, resetting the second, so that finally the flip-flops hold the 4-bit code in which the first, second and third bits represent the number of holes in the second, third and fourth rows of the character matrix, a 0 indicating 1 hole and a 1 indicating 2 or 4 holes, except that 4 holes in the third row produces a 0 in the second bit and a 1 in the fourth bit (the latter being otherwise 0).

Title: Method of making an inlay casting mould or a precision casting mould from a wax pattern
IPC: A61C13/00
Filed: 1957-12-16
Abstract: 843,412. Making moulds for dental &c. casting. ABE, E. Dec. 16, 1957, No.39099/57. Class 87(2). [Also in Group XXII] A mould is made, using a wax pattern, by a method in which a steel sprue tube 4 is heated and secured to the wax pattern 3 by inserting it therein and then investing the pattern with compound 22, e.g. a mixture of gypsum, silica and sodium chloride, in a casting ring 21 so that the end of the tube projects from the compound, the wax pattern then being heated from the outside at 580‹ to 720‹C to eliminate the wax. Deformation of the wax pattern, as by swelling about the bottom of a hot sprue wire, is avoided due to the entry of excess molten wax into the tube. The tube may, for example, be first inserted into wax which fills a tooth cavity, and is preferably of stainless steel and with a hole 7 surrounded by a wax ring 20. A double tube 8, 10, Fig. 5, may be used, or an outer tube and inner wire. Insulation compound 17, containing asbestos and mica, may be baked on the lower part of the outer tube 8. The tube and pattern 4, 3 are set up in a wax block 18 at the top of a conical base 19, which also supports the casting ring 21, and when the investment compound has set the casting ring is removed and gradually heated from the outside by an electric heater, gas flame or charcoal fire, the volatilized waxes and combustion products escaping through the sprue tube 4, or the outer tube 8. The wax ring 20 leaves a reservoir from which, when molten metal is cast, the mould cavity is maintained filled with metal to compensate for shrinkage.

Title: Methods and apparatus for regeneration of granular activated carbon
IPC: C01B31/08
Filed: 1961-11-09
Abstract: A process for regenerating granular activated carbon employing a multiple hearth furnace (see Division F4) comprises: progressively feeding the carbon granules from the top to the bottom of the furnace while applying heat from a number of heat sources to more than one hearth, supplying air at a number of points to more than one hearth, dissipating heat from the furnace at a rate substantially exceeding that effected by the nitrogen in the supplied air, and rapidly and repeatedly exposing the carbon granules to the hearth atmosphere. The heating, cooling, and air supply means are controlled to maintain a temperature gradient of about 900 DEG  F. at the top of the furnace to 1900 DEG  F. at the bottom. Burners providing the heat source may be required only for starting the process, which is predominantly exothermic when established. Carbon dioxide and water vapour in the furnace atmosphere react at the furnace temperatures with some of the carbon to form carbon monoxide and hydrogen which combine exothermically with oxygen in the supplied air to form carbon dioxide and water <PICT:0941635/C1/1> vapour, the heat produced being considerably in excess of the heat requirements of the first reaction.  Heat is dissipated by the nitrogen in the supplied air, and in addition cooler gases are recirculated from the top of the furnace to the lower hearths, some heat being dissipated in the recirculating ducts.  Heat may be dissipated also by spraying water into the recirculated gases, circulating water through pipes around the furnace walls.  A carbon burn-off rate of at least 0.3 lb. per hour per square foot of hearth area is achieved.  Repeated exposure of the carbon granules to the furnace atmosphere is achieved by rabble teeth. Specification 643,282 is referred to.
