Abstract: 751,604. Feeding sheets. FRENCH, L. J. B. R. Jan. 4, 1955 [Jan. 4, 1954], No. 158/54. Class 100 (1). [Also in Groups XV and XXX] Piles.-In book cover applying mechanism, the covers are piled on a table 32 mounted on a post 33 formed with rack teeth 34 engaged by a gear wheel 35 rigidly associated with a gear wheel 36 of larger diameter driven from a small diameter associated gear wheel 37 with which is associated a ratchet wheel 38, both on a shaft 41. The ratchet wheel 38 is operated by a pawl 39 carried by a link 40 suspended from shaft 41 and connected by a rod 42 with an eccentric 43 operated from the driving shaft 44 which is driven from a motor 6 (not shown) each time a cover is applied. A pawl 95 serves to prevent reversal of movement of the ratchet wheel 38 and the pawl 95 can be actuated by a push rod 96 to set the mechanism initially. The pawl 39 is held out of operative engagement with the ratchet wheel 38 by a shaped end 100 of a lever 98 fulcrumed at 99 and connected at its other end to the spindle 97 of a solenoid G, the solenoid G being energized by a microswitch F which engages the top cover 101 of the pile and operates when the level of the pile falls below a certain limit, not necessarily each time a cover is removed. Separating.-The top cover 101 is lifted at its leading edge by a series of suction cups 62 along a bar 61 mounted on an arm 63 pivoted at 64 to a slide 60 and spring pressed to the raised position shown. The cups 62 are connected with suitable mechanism for obtaining reduced air pressure through the medium of a sliding valve 90 moved in one direction to provide suction by a lever 65 and released when the cover has been moved by a bar 91. The lever 65 is pivoted at 66 and connected by a rod 67 to a bell crank lever 68 having a follower 69 engaging a cam face 70 on a disc 48 on the shaft 44, the lever 65 first pressing down the valve 90 and then the arm 63 to press the cups 62 into contact with the leading edge of the top cover 101. Forwarding.-The slide 60 with the arm 63 and bar 61 is moved forwardly to position a cover over a platform 74, by a lever 58 connected by a pin 59 and having a pin 56 and slot 57 connection with a lever 54 pivoted at 55. The lever 54 is operated from a cam groove 49 on the disc 48 by a follower 50 on a link 51 having pin 52 and slot 53 connection with the lever 54. The cover is released by the bar 91 engaging the valve 90 and moving it upwardly, the bar 91 being raised by a lever 92 pivoted at 93 and actuated by a cam 94 on the disc 48. The motor 6 (not shown) which operates the shaft 44, is started by a relay energized by switches operated by levers in the path of the book to be covered.

Title: Improved prepayment mechanism for electricity with an adjustable stepped gear arrangement for altering the price per unit
IPC: G07F15/08
Filed: 1940-01-03
Abstract: 537,668. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. Jan. 3, 1940, No. 171. Convention date, Sept. 10, 1939. [Class 27] In the type of price-charge mechanism for meters having a stepped gear wheel engaged by a toothed wheel which moves both axially and angularly to engage the different wheels in the stepped formation, the movable toothed wheel is carried by an axially and longitudinally moving setting lever co-operating with a fixed stepped supporting member or stop to ensure correct mesh of each set for engaging gears; the movement of the lever being controlled by a helical spring which resists the longitudinal movement by compression and the angular movement by torsion. Thus in Fig. 3 the stop blocks I, II prevent the levers 14, 14' moving both angularly and axially in one direction under the influence of the springs 61, Fig. 1. Correct engagement between the wheel 10 and any one of the stepped wheels 3 ... 9 is thus ensured. The two arms 10, 10<SP>1</SP> shown engaging the opposite sides of the stepped gear are for settings of the value of one penny and one eighth of a penny respectively. These two arms are coupled through gearing to the sun wheels 35, 36 respectively of a differential gear of which the planet wheel shaft is connected through gearing to the quantity mechanism. Specification 469,676 is referred to.

Abstract: 541,466. Making sliding-clasp fasteners. UNITED STATES RUBBER CO. Jan. 9, 1941, No. 308. Convention date, Jan. 20, 1940. Addition to 496,472. [Classes 83 (ii) and 83 (iv)] Angular bending; shearing; embossing.-In a machine for making interlocking members of sliding-clasp fasteners as in parent Specification the knife 15, Fig. 6, which cuts an element from the section strip 10, receives this in a recess 29 shaped to hold and transfer the element cut off to a position between the dies 191 and 38 which shape it. The strip is fed by rollers 11, Fig. 3, of which the lower is intermittently rotated by a ratchet operated from a cam on the main shaft 50. Reverse movement of the rollers is prevented by a friction brake. The strip is straightened by a spring-returned rod 130 intermittently pressed down by a lever 135 and cam 49. The knife is operated by a cam 46 and the dies 191, 38, which are adjustably carried by spring-returned slides 19, 18 by cams 47, 48. The recess 29 has an enlargement not occupied by the element 23, and a portion 34 of the die 19<SP>1</SP> is thus able to form the rounded end 36<SP>1</SP> of the element. Spring-pressed ejectors 41 release the element 23 from the die 191 when this retires and thus retain the element in the recess 29 by which it is then brought opposite an ejector 20, operated by the cam 49, and a shoot 22 as shown in Fig. 6. The knife is then returned to its lowest position and a further length of the strip is fed.

Title: Automatic temperature control for a glass molding process
IPC: C03B11/12
Filed: 1966-01-04
Abstract: <PICT:1107471/C1/1> A method of moulding an article wherein a charge of hot glass is placed in the cavity of a mould and a plunger is pressed into the cavity to form an article comprises, maintaining a predetermined difference between the mould and plunger temperatures so that, when the plunger is withdrawn from the mould cavity the moulded article stays with the hotter of the plunger and mould. Preferably the article is caused to stay with the mould.  A thermocouple placed in the mould senses the temperature of the mould and feeds its information into a function controller and thence into a mould controller.  In this latter there is a manually set point which indicates the desired mould temperature. Another thermocouple in the plunger sense the plunger temperature which information is fed into a plunger controller.  This latter also receives a signal from the function controller (see Fig. 1) dependent upon the signal from the mould thermocouple.  Thus when the mould controller receives a signal which shows a derivation from the set point it operates a valve to increase or decrease cooling air to the mould accordingly. Simultaneously a comparative signal is sent to the plunger controller which also operates a valve to increase or decrease cooling air to the plunger to thus maintain a predetermined temperature difference between the mould and the plunger.  The article thus pressed may be a dinner plate. Pyrometers may be used in place of thermocouples.

Title: System for ionizing gaseous fluid
IPC: F15D1/02
Filed: 1974-01-07
Abstract: 1449343 Boundary layer control; pistons H FIMML 7 Jan 1974 [5 Jan 1973] 664/74 Headings F2R and F2T Means for reducing surface resistance between a gas and a wall or for repelling the gas from the wall comprises the provision of a coating, e.g. barium oxide which when heated will emit electrons to ionize the gas, the wall being maintained at a negative electrical potential to repel the ionized gas. In an embodiment for reducing surface resistance in a jet tube 1 of a turbo-jet engine the inner wall of the tube has a coating 10 which is caused to emit electrons by the injection, from a nozzle or nozzles 2 of hot gas from the engine combustion chamber. Alternatively a backing heating coil may be embedded in the wall of the tube. The coating 10 is negatively charged to repel the ionized gas from its surface. In an embodiment for repelling gas, e.g. in the gap 19 between a piston 14 and cylinder 17 of an internal combustion engine a coating 10<SP>1</SP> is applied to the wall of the piston which when heated, e.g. by a heating coil embedded in the wall of the piston, will discharge electrons to ionize the gas. A ring 15 and the wall of the cylinder 17 are maintained at a negative electrical potential, thereby repelling the ionized gas to form a barrier against its flow past the piston.

Abstract: 656,377. Shaft couplings. BENDIX AVIATION CORPORATION. Jan. 10, 1949, No. 673. Convention date, Feb. 2, 1948. [Class 80(ii)] In a drive from an internal combustion engine or other prime mover to the armature 23 of a generator, of the kind in which the drive passes to an armature-supporting quill shaft 51 through a resilient pencil shaft 42 and a friction coupling 81, 82 in parallel, the coupling spring 96 is so arranged as not to bias any portion of a broken pencil shaft towards the engine. The shaft 42 is powered from the engine through a splined end 41 and at the remote end is slidably splined to the quill shaft 51. A compression spring 96 acts between an end cup 98 on the shaft 42 and a plate 97 rotatable on the quill 51, so as to bias the shaft 42 away from the engine and bring flat plates 81, 82 into driving contact through a friction element 83 on the plate 82. On breakage of the shaft 42, the spring-biassed portion thereof is pressed away from the engine-driven portion and the cupped plate 98 abuts a braking surface on a cap 100 secured to the generator housing to bring the rotor 26 to rest. The cap 100 serves through a bolt 104 to retain a cover cap 102 having an air spout 103.

Title: Specific gravity indicator
IPC: G01N9/34
Filed: 1945-01-09
Abstract: 615,518. Fluid-flow meters. FISCHER, K. Jan. 9, 1945, No. 731. Convention date, May 15, 1944. [Class 69 (i)] [Also in Group XX] In a flow-meter comprising a main flowconstricting member 47, Fig. 1, mounted within a downwardly tapering tube 20 and connected by a rod 50 to a weigh 49 mounted in a guide tube 34, a second flow-constricting member 51 is mounted freely on the rod 50. The main member 47 is of considerable negative buoyancy and accordingly insensitive to changes in specific gravity of the fluid while the member 51 is of only slight negative buoyancy and therefore sensitive to changes in the specific gravity; changes in specific gravity are thus indicated by relative differences of level of the two members. As shown the member 47 comprises a conical cup with a bevelled edge engaging longitudinal guidebeads in the tube 20, the member 51 also being conical. In a modification, the weight 49 is dispensed with, the tube 34 being narrower to guide the rod 50. In another modification, the rod 50 is replaced by a tube slidable on a central fixed rod, the guide-beads on the tube 20 then being dispensed with. In a further modification, the upper extension tube and rod- and-weight arrangement are omitted, the main flow-constricting member comprising a pair of conical cups 57, 58, Fig. 8, connected by a thin rod 59, and engaging longitudinal guide-beads as before. The second flow-constricting member is similarly constructed, but it also engages the guide-beads. On this account and also because of its slight negative buoyancy this member tends to move up considerably in response to slight increases in flow-rate. This tendency is counteracted by providing byepass openings 82, 83 in the conical surfaces 63, 64 respectively. It is stated that the forms of flow-constricting member described render the readings insensitive to changes in the viscosity of the liquid. In all embodiments, the position of the lower member may be taken as an indication of flow-rate independent of changes in the specific gravity. Specifications 579,779, 615,412 and 615,413 are referred to.
