Abstract: 1,246,073. Dispensing containers. P. PETRIE. 17 March, 1970, No. 12771/70. Heading B8P. [Also in Division G3] A watch band calendar and dispenser comprises a stack of calendar sheet elements positioned in a container having a window in its top face and a slot at one end. A spring member pushes the stack upwardly to align the top most element with the slot. As shown in Fig. 1, each calendar element 25 displays dates for one month on at least its upper face, these dates being visible through the window 22 in the container cover 12. The spring member 11 has flat locating end portions and a cut-out central semi-cylindrical portion which has curled edges 19, 20 for engaging the bottom of the stack of elements. The box part 10 of the container-has a peripheral channel 14 into which a rib 23 on the cover may be pushed, and the joint may be secured by ultrasonic welding. In use, the top most element may be ejected through slot 24 by applying a thumb through the window 22. The dispenser may be reloaded by pushing elements in through the same slot. Ejected elements are secured to the watch band either by pushing the band through openings 28, 29 in the element, or by bending the element around the band, Figs. 5 and 6 (not shown).

Abstract: 496,635. Machines for grinding valve seats. SOC. PARISIENNE D'OUTILAGE ELECTRIQUE. April 29, 1938, No. 12840. Convention date, May 14, 1937. [Class 60] In a machine for trueing-up valve seats, a planetary movement is movable in a casing comprising handles for manipulating and guiding the machine and during the operation of the machine, the casing remains stationary and insensible to the reactions of the planetary movement. The machine comprises a grinder 9 mounted on a pinion 5 rotated through a pinion 21, on a hollow shaft 21a, by external power, the pinion 5 being rotatably mounted on an eccentric portion of a shaft 4 rotatable in bearings 2, 3 in the machine casing 1. A pinion 22, rigid with the pinion 21 meshes with a pinion 13 on a stationary shaft carried by a frame 10 loose on the eccentric part of the shaft 4 and a worm solid with the pinion 13 engages a worm-wheel 15 pinned to the shaft 4 which thus receives a slow rotary motion resulting in the grinder 9 executing a planetary motion about the axis of the shaft 4. To permit the necessary oscillatory movement of the frame 10, the frame is carried by an arm 10c extending through the shaft 21a and pivoted at 20 in one of the manipulating handles 17, 18 on the casing 1. The machine is centred on the valve seat by a shaft 27 inserted in the valve guide and passed up through the hollow shaft 4 to an extent determined by a micrometer screw 26.

Title: Improvements in gas meters
IPC: G01F3/22
Filed: 1922-05-10
Abstract: 206,867. Kugler, G. May 10, 1922. Closure members, hinged. -The fluctuation of pressure which arises on every reversal of the measuring member in a gas meter is equalized by suddenly moving the valve by means of a drop weight raised by the action of the measuring member into an intermediate position as well as into the end positions, in which intermediate position the inlet and outlet passages are connected with one another. The meter has one diaphragm or like member c controlling a single valve m by means of a lever d operated in known manner, the valve being mounted on a cross rod q carried by arms t rotatably mounted on an axis a. Attached to the arm l is a second cross rod o the ends of which project into slots p provided in the drop-weight member g, h. In operation, the lever d engages the member g, h by means of one or the other of two projections u carried thereon and causes it to move and operate the rod q to raise the valve from its seat n, as shown in Figs. 5, III, and 2. The drop weight then continues its movement under the influence of gravity to move the valve to its second position of rest. Alternatively, the valve may be so operated as to stand stationary in the intermediate position to overlap the outlet and both inlets in part.

Cards, wire, extracting teeth from.-In a machine for removing sections of teeth from cardclothing to provide clear spaces, the clothing A is passed, teeth downwards, through a frame 10 with side guiding-walls. The clothing passes under a plate 11, Fig. 3, and is gripped by a plate 12 carried by a support 18, Fig. 8, controlled by springs 19 and cams 17 on a shaft 13 operated by a handle 14. The shaft 13 also carries a cam 23 which raises a plate 24, mounted on a pivoted member 20, between the plates 11, 12, and forces the teeth B upwards through the clothing as far as the bend in the wires. The clothing is then released by a return movement of the handle 14, and is passed on automatically or by hand to a member 36 provided with ploughs 40 to engage the raised staples and adapted to be moved longitudinally by a handle to extract them. The clothing is gripped, as this is being done, between a resilient surface 45 on a spring-controlled wedge-shaped member 42, Fig. 4, and an upper plate 47. The return movement of the handle, which moves the member 36 through a rack and pinion) presses the rack against the extension 41 on the wedge-shaped member 42, and releases the card-clothing A. The member 36 is adjustably mounted in its carriage 30, both vertically by a screw 37 and as to its inclination bv screws 38. The card-clothing is positioned by an adjustable side guide whilst being acted on by the ploughs 40.

Abstract: 133,710. Hasler, Akt.-Ges. vorm. Telegraphenwerkstatte von G. Hasler. Oct. 10, 1918, [Convention date]. Time-distance recorders of the kind in which a clock-driven recording-point moves across a vehicle &c. driven strip, are provided with two recording-points, one of which records minutes by making a complete movement across the strip in an hour white the other traverses the strip once in twenty-four hours and is depressed to puncture it once per hour.

[Classes 83 (ii) and 83 (iv)] Brazing.-In joining parts of heat exchangers formed of tubular or plate-like elements composed of or provided at least at the joining surfaces with copper or a copper base alloy, a thin layer of metal or alloy melting below 350‹ C. and capable of forming an alloy with the copper &c., is interposed between the surfaces, the parts are assembled and heated in a non-oxidising or reducing atmosphere to a temperature which is below the melting point of the copper &c., but is sufficiently high to cause the layer to alloy with the copper &c. to form a bonding alloy with a melting point not lower than 500‹ C., and then allowing the assembly to cool whilst still in the said atmosphere. The base of a copper &c. coated element may consist of steel or ferrous alloy or other metal having a melting point not lower than the temperature used in forming the joints. The coating may be rolled on the base metal. The interposed metal or alloy may consist of tin, cadmium or their alloys, or alloys of lead, e.g. 50 per cent each of tin and lead, or 95 per cent lead and 5 per cent silver. It may also contain up to 3 per cent of copper. The layer may be 1/50 to 1/5 of the thickness of the elements adjacent the joining surfaces. The layer may be applied electrolytically, by hot dipping, by spraying, as a paste consisting of a comminuted metal in a medium such as a solution of nitrocellulose, or as a thin foil inserted between the surfaces. The atmosphere may comprise nitrogen or hydrogen, or a mixture thereof obtained by admixture, or from cracked ammonia. It may also comprise burnt coal gas which may be previously purified. In one method, the steel sheets may be electrolytically coated with copper then dipped in molten tin and then assembled and heated in an atmosphere of burnt coal gas to 800‹ C. for 10-20 minutes and then allowed to cool in such atmosphere. The parts of a heat exchanger which require liquid-tight joints and non-liquid-tight joints, may be coated adjacent the parts to be liquid-tight with silver instead of with the low melting point metal or alloy which is applied to the other parts. Heating is then effected as in the previous case to a temperature below the melting point of the surface metal, but sufficiently high to bond all the elements together. The silver coating may be effected by electrodeposition or rolling. When the two coatings are to be formed on a single element, the silver coated elements are clamped together and the edges sealed with molten wax or lacquer to prevent access of the electrolyte thereto when electrodepositing tin on the exposed surfaces.
