Title: Sliding-clasp fastener and method of making the same
IPC: A44B19/04
Filed: 1937-01-13
Abstract: 472,518. Sliding - clasp fasteners. PRENTICE MANUFACTURING CO., G. E. Jan. 13, 1937, No. 1049. Convention date, Feb. 3, 1936. [Class 44] The fastener elements of a sliding-clasd fastener have affixing jaws which, prior to attachment to the stringer, are substantially parallel and separated by a recess having the same contour and dimensions as the head of the fastener. This allows the elements to be cut from a strip of suitable width without waste, as shown in Fig. 5. As shown, the parallel jaws 14, 15 are separated by an arcuate recess 17 identical in form with the head 24 in which a recess 25a is formed together with a projection 25 on the opposite face, Fig. 4. The shoulders 20, 21 are inclined at the same angles as the terminal faces 18, 19 of the jaws. The bottom of recess 17 is approximately midway along the length of the element. When applied to the stringer la, Fig. 6, the jaws 14, 15 are curved, with the faces 18, 19 bearing flat against opposite faces of the stringer. The maximum width of the element, defined by the points 26, 27, lies approximately in the central plane OP of the bead 3 on the edge of the stringer. The jaws 14, 15 being shorter than usual, give greater flexibility to the fastener. When the fasteners are interengaged, Fig. 13, channels are presented on opposite faces of the fastener, and the slider, comprising upper and lower plates 35, 36 connected by the usual wedge member, not shown, is crosssectionally shaped to conform with the fasteners. When used with bags or tobacco pouches &c. having substantially parallel walls, the elements may interengage at an angle, Fig. 20, the slider correspondingly comprising a flanged upper plate 38 and a narrower substantially flat lower plate 41. The fasteners may have covering strips of fabric &c. applied to one or both faces, the arrangement being of the kind in which the covering strips pass through the slider. In applying the strips, the fasteners are first interengaged and covering strips 30, 31, Figs. 8, 9, are secured to one or both faces of the fastening by adhesive, stitching, &c. The strips are then severed lengthwise by cutters 32, 33. The free edges 30a, 31a of the strips may be treated with a binding agent such as cellulosic cement to prevent fraying in use, but the strips may be of braided or other textile which does not readily fray. If desired, the covering strips may be left unsevered at one end of the fastening, if the stringers are not to be entirely detachable from one another. The slider depresses the edges 30a, 31a of the strips into the channels along the fastening.

Abstract: 1478802 Coffee mills S L L CAILLIOT and L G P ANDRE 13 Jan 1975 [14 Jan 1974 11 Oct 1974] 1312/75 Heading B2A A coffee mill comprises a vertical screw 1a Fig. 1 having a helical groove and co-operating with a preferably bilobate frusto-conical crushing chamber 2 whose section decreases towards a cylindrical bore 2d Fig. 7 which guides the lower part of the screw. Two diametrically-opposed slots 29 are arranged in the bore surface. At least one of these communicates with a duct to feed ground coffee to a discharge chute. The screw is adjustable to vary the grinding fineness by rotation of a knob 6. The pitch and the depth of the groove both decrease progressively towards the lower extremity of the screw. The crushing chamber is itself rotatable and includes a cam surface 2b Fig. 3 cooperating with a microswitch 14' in the motor circuit. When the screw is driven by the motor 9 and a centrifugal clutch 10-13 if there are coffee beans in the chamber the chamber rotates a little way and the microswitch remains energized. When the beans are all ground the empty chamber is urged back by a spring 15 which brings a roller 16 towards a stop 26 and the movement of the cam surface of the chamber deenergizes the microswitch and motor. When a receptacle 20 is full linkwork 23, 17 operates permitting the roller 16 to descend on a cam surface 17a of the linkwork and again the chamber rotates cutting off the motor. If a hard uncrushable object is in the chamber the chamber is rotated further and overcomes the resistance of springs 15, 19 and the roller 16 strikes a limit stop 25 Fig. 5. The roller pushes towards the bottom of the lever 17. The boss 2c of the cam ceases to push against the microswitch and the motor cuts off in the same way as happens when the receptacle is full. The apparatus can form part of a coffee-making machine.

Patent GB-722915-A (GB)
Title: Process for producing a hard and wear-resistant surface on ferrous bodies
IPC: C23C10/02
Filed: 1952-01-17
Abstract: Ferrous articles having an available carbon content of 0.4 per cent or more, depending on the depth of ferrous material below the surface, are coated with vanadium whilst maintaining the surface at high temperature, the deposited vanadium combining with the carbon of the ferrous material to form an integral surface layer containing vanadium carbide, the carbon content of the ferrous material being initially selected in relation to the depth thereof so that sufficient carbon is available for forming carbide with substantially all the vanadium deposited.  The vanadium may be deposited by chemical reduction or reaction at the surface, e.g. by hydrogen reduction of, or exchange reaction with, a vanadium halide, or by thermal decomposition of a halide or carbonyl. Prior to treatment, work-affected surfaces may be removed by anodic treatment or by immersion in 50 per cent hydrochloric acid at 85 DEG  C. for 2-10 minutes.  A stop coating of copper may be applied to those parts of the surface where vanadium deposition is not desired.  Carbon may be added to the article by a carburising process, a similar stop coating being applied to suppress carburisation where desired.  In depositing vanadium by decomposition of its chloride, selective induction heating may be employed.  The ferrous articles may be packed in (a) 50 per cent ceramic, balance ferro-vanadium; or (b) 20 per cent titanium oxide, balance ferro-vanadium, and placed in V-Ni-Fe alloy baskets which are heated in a retort at 900-1200 DEG  C. in a stream of hydrogen and hydrogen chloride, alternating with a stream of hydrogen.  Carburisation may be effected in a pack of 20 per cent barium carbonate bound to hardwood charcoal with oil, tar or molasses at 925 DEG  C.
